Description

Garbage winnowing treatment system

Technical field

The invention relates to the technical field of environmental protection equipment, and in particular to a garbage winnowing and processing system.

Background technique

Most construction waste, decoration waste, and domestic waste are disposed of in simple landfills, and these wastes are not available anywhere. Since there is no strong legal protection system for the front-end classification of garbage, the composition of garbage is relatively complex, including materials with different proportions and ingredients, most of which are recyclable. For example, scrap metal can be recycled and reused in manufacturing. Steel, concrete, bricks and tiles can be used as recycled sand and gravel, and light materials such as plastics, paper, and fiber fabrics can be used as combustibles to incinerate to generate electricity instead of natural energy. The sorting of light materials in mixed waste is achieved by a wind separator.

The air separator has gradually become the basic equipment for the sorting process of kitchen waste, construction waste and other fields of light and heavy materials. For example, CN212237647U discloses a construction waste treatment system. The working process is as follows: a loader sends construction waste into a jaw crusher for crushing, then the construction waste is screened and classified, and then metal impurities are selected through magnetic separation equipment. Afterwards, it is processed by a box-type air separator and turned into coarse aggregate, which is then secondary crushed by an impact crusher. The size of the aggregate is then classified by two screening equipment, and the folding plate air separator removes impurities and becomes coarse aggregate. Refined recycled aggregate is usually used for filling slope blocks.

For the above air separation system, the folding plate air separation machine performs final impurity removal to obtain recycled aggregates. The folding plate air separation machine usually consists of an air separation box, a fan and a cyclone separator. In the air separation box, Under the action of gravity, heavy materials are discharged through the discharge port of the air separation box, while light materials enter the cyclone separator with the wind and are discharged.

The above-mentioned air separation system falls rapidly in the air separation box, which easily causes light materials and heavy materials to be discharged through the outlet of the air separation box together. Therefore, the recycled aggregate obtained by the above-mentioned sorting system also contains a large amount of light materials. As a result, the recycled aggregate cannot play a very good role when used.

Contents of the invention

The invention provides a garbage air separation processing system that improves separation efficiency.

The technical solutions to solve the above problems are as follows:

The garbage air separation processing system includes a decentralized air separator, a crusher, and a folding plate air sorting machine. The decentralized air sorting machine is connected to the crusher, and the folding plate air sorting machine is connected to the decentralized air sorting machine or crusher. The winnowing machine includes a winnowing box, a first fan and a separator. The winnowing box is connected to the first blower and the separator respectively. The upper part of the winnowing box is provided with a material inlet, and the lower part of the winnowing box is provided with a discharge port. The air selection box is provided with a first buffering and dispersing component and a second buffering and dispersing component connected to the winnowing box. The first buffering and dispersing component and the second buffering and dispersing component are arranged at intervals. Between the first buffering and dispersing component and the second buffering and dispersing component, A first channel is formed between the dispersed components;

The first buffering and dispersing component includes a plurality of first buffering and dispersing plates that buffer and disperse the material. These first buffering and dispersing plates are connected in sequence to form a first wave peak and a first wave trough. The second buffering and dispersing component includes a plurality of first buffering and dispersing boards that buffer and disperse the material. Second buffering and dispersing plates are used to buffer and disperse. These second buffering and dispersing plates are connected in sequence to form a second wave peak and a second wave trough.

In the present invention, since a plurality of first buffering and dispersing plates are connected in sequence and form a first wave peak and a first wave trough, a plurality of second buffering and dispersing plates are connected in sequence and form a second wave peak and a second wave trough, so that the first buffering and dispersing plates are connected in sequence and form a second wave peak and a second wave trough. The components form a rolling structure, and the second buffering and dispersing component forms a rolling structure. When the material enters the air separation box, the material falls on the rolling first buffering and dispersing component and is transferred to the rolling third after impact. The second buffering and dispersing component collides with the second buffering and dispersing component, and then transfers from the second buffering and dispersing component to the first buffering and dispersing component and collides with each other. Such repeated collisions disperse the material and reduce the falling speed of the material, thus improving the stability of the light material and the first buffering and dispersing component. The separation efficiency of recycled aggregate greatly reduces the light materials contained in the recycled aggregate. When the recycled aggregate is applied to the filling of slope blocks, it can play a better role.

Detailed ways

The light and heavy materials involved in the following content refer to light materials and heavy materials with larger weight. Heavy materials with larger weight refer to heavy materials that fall into the material accumulation component after being separated from the light materials during air selection. .

As shown in Figure 1, the garbage air separation processing system of the present invention includes a decentralized air classifier, a crusher, and a folding plate air classifier. The decentralized air classifier is connected to the crusher, and the folding plate air classifier is connected to the dispersed air classifier. The separator or crusher is connected. In this embodiment, the folding plate air separator is connected to the crusher. Preferably, in this embodiment, a jaw crusher is provided upstream of the folding plate air separator.

The loader sends the construction waste into the jaw crusher for crushing, and then the construction waste is screened and classified. After the metal impurities are selected by the magnetic separation equipment, they are processed by the decentralized air separator and turned into coarse aggregate. Then the crusher performs secondary crushing, and then the size of the aggregate is classified through the screening equipment. The folding plate air separator removes impurities and becomes refined recycled aggregate. The recycled aggregate is usually used for slope blocks. filling.

As shown in Figures 1 to 12, the dispersion type air separator of the present invention includes a dispersion type feed hopper A, a casing B, a belt transmission mechanism C, a separation component D, a blowing device E, a first adjustment mechanism F, and a scraping component G. , return air device H, material accumulation component K, each part and the relationship between each part are explained in detail below:

As shown in Figures 1 to 5, the dispersed feed hopper A is installed on the top of the housing B, and the output end of the material conveying mechanism other than the dispersed air separator is located on the top of the housing B, or above the housing B, so , the feed of the dispersive air separator of the present invention is located at the top of the whole machine.

As shown in Figures 1 to 5, the dispersed feed hopper A causes the materials to fall on the belt conveyor C in a dispersed manner. The output end of the dispersed feed hopper A is located above the belt conveyor C. The structure and working mechanism of the dispersed feed hopper A are described in detail below:

As shown in Figures 1 to 5, the decentralized feed hopper A includes a feed hopper body 1 and a material receiving mechanism. The feed hopper body 1 is provided with a feed port 3, which is used for material input before air separation. In this embodiment, preferably, the feed hopper body 1 further includes a cover body 1a located on one side of the feed port 3 for covering dust, and the cover body 1a is provided with a dust suction component 2.

As shown in Figures 1 to 5, the bottom of the feed hopper body 1 is usually a belt conveyor C that receives materials. When the materials are output from the dispersion type air separator of the present invention, they directly fall on the belt conveyor C. Since the garbage usually It will contain dust, so the shielding effect of the cover 1a can prevent the dust from flying around, and then the dust is drawn away by the dust suction part 2 due to the air induction effect produced by the dust suction part 2.

As shown in Figures 1 to 5, the material receiving mechanism includes a material receiving component 4 and one or more material dispersing components 9 for dispersing materials. The material receiving component 4 has a material receiving surface d that guides the movement of materials. At least a part of the material receiving component 4 Located in the feed port 3, the material receiving part 4 cooperates with the feed hopper body 1. The angle formed between the material receiving surface d of the material receiving part 4 and the axial direction of the feed port 3 is less than 90°. Therefore, the material receiving part 4 The surface d is arranged in an inclined state, so that when material falls on the material receiving surface d, the material slides from top to bottom along the material receiving surface d. Since the material is scattered in all directions after collision with the material receiving part 4, the inclined material receiving part 4 is conducive to dispersing the material.

As shown in Figures 1 to 5, the material dispersing part 9 is arranged on the material receiving surface d of the material receiving part 4. For the material falling on the material receiving surface d, due to the existence of the material dispersing part 9, the moving material is forced to It is dispersed along the material dispersing part 9 to prevent the materials from falling concentratedly on a certain position on the belt conveyor C. Since the air-separated materials fall dispersedly on the belt conveyor C, on the one hand, it is convenient for dust removal, and on the other hand, it is convenient for dust removal on the belt conveyor C. There is no accumulation of materials on C, which improves the uniformity of lateral distribution of materials and the success rate of air selection.

As shown in Figures 1 to 5, in this embodiment, the width of the material dispersing part 9 gradually increases from one end to the other end, and the middle part of the material dispersing part 9 bulges, so that the surfaces on both sides of the middle part of the material dispersing part 9 become The preferred structure of the radial dispersion surface and material dispersion component 9 is a cone shape. The dispersing component 9 of this structure is conducive to better dispersion of materials.

As shown in Figures 1 to 5, in order to better guide the materials and reduce the impact force on the belt conveying mechanism C when the materials fall onto the belt conveying mechanism C, the present invention also includes the method of dispersing the materials dispersed by the material receiving mechanism The skirt 8 is used for buffering and guiding. One end of the skirt 8 is fixed to the hopper body 1. The other end of the skirt 8 is the discharging end. The discharging direction of the material receiving part 4 is opposite to the discharging direction of the skirt 8. .

As shown in Figures 1 to 5, the surface of the skirt 8 is also an inclined surface, and the angle formed between it and the axial direction of the feed port 3 is also less than 90°. A part of the skirt 8 is located in the feed port 3 , so that when the skirt 8 receives the materials output from the material receiving mechanism, the skirt 8 has a buffering effect on these materials.

As shown in Figures 1 to 5, the other part of the skirt 8 extends to the outside of the inlet 3, thereby shortening the distance between the discharge end of the skirt 8 and the belt conveyor C, thereby reducing the impact of the material on the belt conveyor. C forms the impact force. The part outside the extension of the skirt 8 and the feed opening 3 is in the shape of an enclosure, and the enclosure also has a shielding effect on dust.

As shown in Figures 1 to 5, the present invention also includes an adjustment mechanism for adjusting the inclination angle of the material receiving component 4. The material receiving component 4 is movably connected to the feed hopper body 1 through the adjustment mechanism. By adjusting the inclination angle of the material receiving part 4 through the adjustment mechanism, it can be suitable for air separation of different materials or different air separation speeds.

As shown in Figures 1 to 5, in this embodiment, the adjustment mechanism includes a support component 13, a sliding shaft 16, and a driver that drives the sliding shaft 16 to move. The support component 13 is connected to the feed hopper body 1, and the material receiving component 4 is connected to the support. Component 13 cooperates; the sliding shaft 16 is connected to the material receiving part 4, the side wall of the feed hopper body 1 is provided with a sliding cavity a, and both ends of the sliding shaft 16 cooperate with the sliding cavity a; the driver is connected to the sliding shaft 16.

As shown in Figures 1 to 5, in this embodiment, the material receiving component 4 is preferably a plate-shaped component, and the support component 13 is preferably a shaft component. Both ends of the support component 13 are respectively fixed to the feed hopper body 1. The sliding shaft 16 and at least part of the driver are located in the cover 1a. The material receiving part 4 is provided with a rotating plate seat 15.

As shown in Figures 1 to 5, the sliding cavity a is opened on the side wall of the cover body 1a. The sliding cavity a preferably adopts a strip hole. The sliding shaft 16 has a clearance fit with the sliding cavity a. When the sliding shaft 16 moves along the sliding cavity a, When the material receiving part 4 moves, the sliding shaft 16 drives one end of the material receiving part 4 to move, and because the material receiving part 4 is supported by the supporting part 13, when the material receiving part 4 moves, its inclination angle is adjusted.

As shown in FIGS. 1 to 5 , the material receiving component 4 is provided with an axle blocking arch 14 that limits the movement range of the supporting component 13 , and the supporting component 13 passes through the axle blocking arch 14 . The shaft-blocking arch 14 is composed of an arch portion and blocking portions connected to both ends of the arch portion. After the blocking portion is fixedly connected to the material-receiving component 4, a clearance hole is formed between the shaft-blocking arch 14 and the material-receiving component 4. The supporting component 13 passes through the relief hole, and the diameter of the support member 13 is smaller than the height of the relief hole. Therefore, when the material receiving member 4 moves, if the blocking part on the shaft arch 14 and the support member 13 butt against each other, the material receiving member 13 will 4 cannot continue to move, therefore, the moving range of the material receiving component 4 is the distance between the two blocking parts.

As shown in Figures 1 to 5, the driver includes a pull rod 17, a screw shaft 19, and a support sleeve 22. One end of the pull rod 17 is connected to the sliding shaft 16, and the other end of the pull rod 17 is provided with a nut 18; one end of the screw shaft 19 is provided with threads, and the screw The thread at one end of the shaft 19 is threadedly connected to the nut 18 on the pull rod 17; the other end of the pull rod 17 is provided with an inner cavity b, and the inner cavity b is a stepped hole. The nut 18 is located in the large diameter hole of the inner cavity b, and the screw shaft The other end of 19 is provided with a guide post c, which has a clearance fit with the small diameter hole of the inner cavity b.

As shown in Figures 1 to 5, the support sleeve 22 is fixed to the feed hopper body 1. The screw shaft 19 passes through the support sleeve 22. A sliding sleeve 25 is provided in the support sleeve 22. The screw shaft 19 passes through the sliding sleeve 25. The screw shaft 19 is There are limit components located at both ends of the support sleeve 22 , and the limit components cooperate with the ends of the support sleeve 21 . Since both ends of the screw shaft 19 are limited by the limiting components and cannot move axially, the screw shaft 19 and the pull rod 17 form a screw mechanism. When the screw shaft 19 rotates, the pull rod 17 moves linearly, and the pull rod 17 passes through the sliding shaft 16 The material receiving part 4 is driven to move.

As shown in Figures 1 to 5, the limiting assembly includes a limiting protrusion disposed on the peripheral surface of the screw shaft 19. The limiting protrusion is located on one side of the support sleeve 21. The limiting protrusion is integrally formed with the screw shaft 19. . The limiting assembly also includes a round nut 21 and a semicircular plate 24 located on the other side of the support sleeve 21. The screw shaft 19 passes through the round nut 21 and the semicircular plate 24. The round nut 21 and the semicircular plate 24 can be fixed with the support sleeve 21, or they can Fixed with the feed hopper body 1. A handwheel 23 is also fixed at the end of the screw shaft 19. The handwheel 23 rotates the screw shaft 19 to adjust the inclination of the material receiving part 4, so that the inclination of the material receiving part 4 is adjusted to 40-50°.

As shown in Figures 1 to 5, the adjustment mechanism also includes axial limiting components 10 provided at both ends of the sliding shaft 16, and a positioning component 11 that cooperates with the limiting component 10 to limit the sliding of the sliding shaft 16. The positioning component 11 is connected with the feed material. The bucket body 1 is fixed, and the positioning component 11 is located outside the sliding cavity a.

As shown in Figures 1 to 5, the sliding shaft 16 can be prevented from leaving the sliding cavity a by the axial limiting member 10. The limiting member 10 is Y-shaped, and the limiting member 10 and the sliding shaft 16 are connected through threads. The positioning component 11 is preferably a strip-shaped component. When the limiting component 10 and the positioning component 11 abut, the sliding shaft 16 will be restricted by the positioning component 11 .

The working process of dispersed feeding hopper A is as follows:

As shown in Figures 1 to 5, the front material enters the feed port 3 and collides with the material receiving part 4 due to inertia and gravity. The material is dispersed during the collision, and the material flow center section is thick due to the characteristics of the belt conveyor. The part is forcibly dispersed by the material receiving surface d of the material dispersing component 9, and after deceleration, evenly falls on the main plate surface e of the skirt 8, collides with the main plate surface e again and is dispersed, passes through the skirt 8 and then falls on the belt conveyor mechanism C It collides with the belt conveyor C for the third time and is dispersed, and then enters the next process. Therefore, through the action of the material receiving part 4 and the main plate surface e of the skirt 8, materials are prevented from falling directly onto the belt conveying mechanism C and forming accumulation.

The dust formed by the falling and collision of materials collects in the collection chamber f of the cover body 1a, and is discharged out of the bucket by the dust suction part 2.

According to the material composition, feeding speed, and flow rate, the handwheel 23 can be turned to drive the screw shaft 19 to rotate. Since the screw shaft 19 and the pull rod 17 form a screw mechanism, when the screw shaft 19 rotates, the pull rod moves linearly, thereby causing the sliding The shaft 16 moves in the sliding cavity a, so the angle between the entire material receiving component 4 and the skirt 8 changes. The threads on the screw shaft 19 and the tie rod 17 are both trapezoidal threads. Therefore, through the self-locking effect of the trapezoidal screw pair, the rotation of the handle 22 is stopped, and the material receiving part 4 maintains a constant position. This achieves random adjustment on demand and adapts to production. need.

The first screw rod 56 is threadedly connected to the threaded hole on the first connecting seat 57. The two locking components pass through the first connecting seat 57 and the first assembly hole 32 and then cooperate with the third hole 55 .

As shown in Figures 1, 7 to 9, since one end of the swing arm 52 is hinged with the mounting base 46, when the first driving component drives the other end of the swing arm 52 to rise or fall, the swing arm 52 will form a rotational motion. The height of the blowing nozzle 51 installed on the swing arm 52 is changed, and on the other hand, the angle of the airflow output of the blowing nozzle 51 relative to the material distributing roller 47 is changed. Through the above adjustment, when the distance between the blowing nozzle 51 and the separation component D changes through the first adjustment mechanism, through the adjustment of the second adjustment mechanism and the first driving component, the flow direction of the output airflow of the blowing device E is consistent with the separation component The circumference of D is tangent to ensure the efficiency of winnowing.

As shown in Figures 1, 10 and 11, in the present invention, the position of the belt conveyor C is adjusted by the first adjustment mechanism F so that the material output from the belt conveyor C collides with the separation assembly D. In this embodiment, the material and The collision of the separation component D is the fourth time, which can also cause dispersion. The first adjusting mechanism F is connected to the housing B and the belt conveyor C respectively. The flow direction of the output airflow of the blowing device E is tangent to the peripheral surface of the separation component D. When the material output from the belt conveyor C collides with the separation component D, the light The material moves along the circumferential direction of the separation component D due to the push of the air flow and the rotation of the separation component D. The heavy material after collision performs free fall motion under the action of its own gravity.

As shown in Figure 1, Figure 10 and Figure 11, the material is dispersed through the dispersion hopper A and then falls onto the belt conveyor C. It is transported to the separation component D through the belt conveyor C. The separation of light and heavy materials needs to be completed at the separation component D. . In the present invention, after the position of the output end of the belt conveying mechanism C is adjusted by the first adjusting mechanism F, the material output from the belt conveying mechanism C collides with the distributing roller 47 in the separation assembly D. This relationship brings The advantages are as follows:

(1), the distance between the output end of the belt conveying mechanism C and the material dividing roller 47 is controlled as needed. After the material collides with the material dividing roller 47, the distance between the material and the material dividing roller 47 is very close, and some materials have even been attached to the material. The surface of the distributing roller 47 is covered, and the flow direction of the output airflow of the blowing device E is tangent to the circumferential surface of the separation component D. Under the combined force of the air flow and the distributing roller 47, the light material moves with the distributing roller 47. Therefore, this collision relationship not only relies on the air flow blown out by the blower to separate light materials and heavy materials, but the combined force of the air flow and the distributing roller 47 takes away the light materials, thereby improving the separation effect. . The invention is particularly suitable for air separation of construction waste. The advantages of the invention are: improving the success rate of air separation and sorting of materials and ensuring the overall working speed of the production line. Expand the adaptability to different materials and reduce the impact of dust particles on the normal operation of the equipment.

(2) After the material collides, the potential energy of the heavy material is reduced. Therefore, when the heavy material falls freely downward, the initial speed of the heavy material is reduced, which reduces the risk of smashing other parts.

(3), since the position of the output end of the belt conveyor C can be adjusted, and the material output from the belt conveyor C will collide with the material distribution roller 47, this avoids the material output from the belt conveyor C falling directly on the The blower nozzle 51 is put on and the blower nozzle 51 is damaged.

In the present invention, after the first adjusting mechanism F adjusts the belt conveying mechanism C, the position where the material output from the belt conveying mechanism C collides with the separation assembly D is the middle and upper part of the separation assembly D, that is, the preferred collision position is at the separation assembly D. After the collision occurs at the middle and upper part of the material roller 47, due to the centrifugal force of the material distribution roller 47 and the force of the air flow, the light materials are more likely to move with the material distribution roller 47, thereby making the air separation effect better.

As shown in Figures 1, 10 and 11, the first adjustment mechanism F includes a lifting bracket 60, a first driving mechanism 61, and a second driving mechanism 62.

The second driving mechanism 62 drives the lifting bracket 60 to move to move the belt transmission mechanism C.

As shown in Figures 1, 10 and 11, when the first driving mechanism 61 works, the first driving mechanism 61 drives the belt conveying mechanism C to rise or fall, thereby changing the height of the output end of the belt conveying mechanism C. When the second driving mechanism 62 works, the second driving mechanism 62 drives the belt conveying mechanism C to move horizontally (the belt conveying mechanism C slides with the inner bracket 31 of the housing B), thereby changing the output end of the belt conveying mechanism C and the separation assembly D. The distance between the distributing rollers 47 in . When both the first driving mechanism 61 and the second driving mechanism 62 adjust the belt conveying mechanism C, the height, horizontal position and discharging angle of the output end of the belt conveying mechanism C can be changed. Therefore, through the action of the above-mentioned first adjusting mechanism F, it can be ensured that the material output from the belt conveying mechanism C collides with the material distribution roller 47, thereby achieving the purpose of improving the air separation efficiency.

The scales 64 are respectively installed on the second connecting frame 60b and the second driving mechanism 62. When the screw mechanism works, the second connecting frame 60b is driven to face each other. When the first connecting frame 60a rises or falls, the scale 64 rises or falls along with the second connecting frame 60b, so that the lifting size can be judged. When the second driving mechanism 62 drives the belt transmission mechanism C to move horizontally, the horizontal movement can be judged. Size, through calculation can determine whether the adjustment position is appropriate, providing a basis for precise adjustment.

In the present invention, the second driving mechanism 62 also adopts a screw mechanism. The screw mechanism in the present invention can be manual or electric. The linear drive mechanism can also use linear drive components such as cylinders and hydraulic cylinders.

Therefore, the particulate matter contained in the airflow is blocked by the baffle 81c. The particulate matter is blocked by the baffle 81c and enters the discharge valve assembly 81d, so that part of the particulate matter returns to the settling chamber 34 for settling, thereby reducing the particulate matter entering the blowing device E.

As shown in Figures 1 and 15 to 19, the second return air component 82 includes a second return air duct 82a connected to the first return air component 81 and an inspection door 82c.

S2, after the adjustment is completed, the material enters the feed port 3 of the dispersed feed hopper A, and collides with the material receiving part 4 due to inertia and gravity. The thick part formed by the characteristics of the belt conveyor in the center section of the material flow passes through the material. The receiving surface d of the dispersing part 9 is forcibly dispersed, and after deceleration, it evenly falls on the main plate surface e of the skirt 8, passes through the skirt 8, and then falls on the belt conveyor mechanism C.

S3, the material output from the belt conveyor C collides with the separation component D. After the collision, the light material moves along the circumferential direction of the separation component D due to the push of the air flow and the rotation of the separation component D. The heavy material after the collision The material falls freely under the action of its own gravity and enters the first accumulation platform 91 or the second accumulation platform 92 of the accumulation assembly K. The material falling from the first accumulation platform 91 or the second accumulation platform 92 falls from The opening of the enclosure 90 drops onto the conveyor mechanism located below the opening. It is transported to the crusher through the conveying mechanism. After being crushed by the crusher, it is transported to the first feeding port 111a. After the material is evenly distributed by the material unloader, the material enters the folding plate air separator and is air separated by the folding plate air separator. Then obtain recycled aggregate.

S4, the material distribution roller 47 rotates toward the settling chamber 34, thereby driving the light materials into the settling chamber 34 for settling; the materials settled into the belt transmission mechanism 42 are sent away by the belt transmission mechanism 42.

S5, the airflow enters the blowing device E through the return air input component 80, the first return air component 81, the second return air component 82, and the return air output component 83 in sequence.

In step S2, according to the material composition, feeding speed, and flow rate, the handwheel 23 is turned to drive the screw shaft 19 to rotate. Since the screw shaft 19 and the pull rod 17 form a screw mechanism, when the screw shaft 19 rotates, the pull rod moves linearly. Then the sliding shaft 16 moves in the sliding cavity a, so the angle between the entire material receiving part 4 and the skirt 8 changes, thereby adjusting the dispersion force of the material and the output speed of the material from the dispersion type feed hopper A.
