Description

Apparatus for washing aggregate for use in a recycling system of waste materials}

The present invention relates to a construction waste regeneration treatment system for classifying and regenerating soil powder, stone powder and aggregate from construction waste. More specifically, it is possible to wash soil powder, cement powder, etc. by washing recyclable aggregate in construction waste shredded to an appropriate size. The present invention relates to an aggregate cleaning device for a construction waste regeneration treatment system, which is capable of reliably separating and removing unnecessary waste such as waste wood, plastic waste, or cloth mixed with them.

Various concrete structures, such as bridges and apartments, which are created in the process of urbanization and industrialization, are inevitable due to deterioration and deterioration over time, and many construction wastes are inevitable. It is occurring. Moreover, in recent years, the amount of construction wastes is increasing as the reconstruction and redevelopment for the improvement of the residential environment is actively promoted in large cities.

Most of these construction wastes were landfilled, but construction wastes contain soil, concrete, metal, glass, and various kinds of wastes. This follows. In particular, while aggregate demand, which is a limited resource, is rapidly increasing due to the increase in new construction, it can be consumed unilaterally, leading to lack of aggregates, and further promoting environmental destruction by quarrying and mining. It became.

Accordingly, in order to protect the natural environment and to efficiently use shortage resources, there are active measures to deal with construction waste. Recently, most construction waste is being recycled.

Figure 1 schematically shows a general process of the construction waste recycling treatment system for this. First, the construction waste is put into a hopper (S1), and then the soil is removed by transferring to a scalping screen by a conveyor (S2). After the soil is removed, the construction waste is first crushed to a suitable size by a jaw crusher (S3), and then the rebar is removed by an electromagnet separator while being transferred to a vibration feeder (S4). Subsequently, only the aggregate having a predetermined particle size (about 25 mm or less) is screened by the vibrating screen (S5), and then various wastes mixed in the waste aggregate agglomerate are first separated by a specific gravity separation method using a blower (S6).

Next, put the first crushed aggregate lump in the water tank to wash (S7) the cement powder and foreign matters contained in or mixed with it, and dehydrated (S8) by vibrating screen, etc., and then to a smaller size by a cone crusher. Second crushing (S9). Subsequently, after removing the reinforcing bars from the aggregates crushed secondary by the electromagnet separator (S10), only aggregates having a predetermined particle size or less are selected again (S11). Then, the waste mixed in the secondary crushed aggregate is secondarily separated by a blower (S12), and then the aggregate lump is crushed to a smaller size by a cone crusher to be recycled to aggregates having a required particle size or less.

On the other hand, for the quality of recycled aggregates obtained from construction wastes through such a regeneration process, it is more important to remove foreign substances such as soil and cement powder, and to remove unnecessary wastes such as waste wood and waste cloth. It is important.

To this end, a washing process is given during a series of regeneration treatments, and conventional washing apparatuses include, for example, Korean Patent Publication No. 2002-0000186 and Utility Model Registration No. 0301994.

Republic of Korea Patent Publication No. 2002-0000186, a plurality of water injection nozzles installed in the water tank to spray the water of a certain pressure to form a water flow to clean the aggregate and at the same time to float the waste separated from the aggregate on the water surface; It is equipped with a screw to induce continuous water flow in one direction to discharge the suspended substances to the outside of the tank, and force the waste to be discharged and the aggregate is inclined in the opposite direction of the waste in a belt conveyor It is intended to be transported.

However, such a washing device has a problem that some of the waste that is mixed into the waste aggregate is not immediately floated on the surface of the rubbish, submerged deeply and moved to the exit of the belt conveyor, then floats to the surface and is transported to the subsequent process along the waste aggregate.

In other words, the belt conveyor is inclined so that only the outlet end is exposed to the outside of the tank and most of it is submerged in the wash water in the tank. Waste materials transferred from the previous process are put into the needle means of the belt conveyor. They are relatively deep into the tank along the heavy waste aggregate and are moved to the exit of the belt conveyor in the submerged state by the flow of water spray nozzles and floated to the surface. .

In addition, by injecting high-pressure water to form a water flow (water flow) in the water tank (floating) to lift the garbage, there is also a problem that small aggregates conveyed by the belt conveyor is pushed back by the spray water is difficult to discharge to the subsequent process.

Utility Model Registration No. 0301994 injects high-pressure air from the wash water to the top to infuse light wastes from the waste material injected into the tank onto the water and blows out the injured waste out of the tank. It is supposed to be exhausted. At this time, foreign matter such as soil powder separated from the waste material sinks to the bottom of the tank and is discharged by the conveying screw, and the aggregate falls to the conveyor and is discharged along with the subsequent process.

However, this technique is relatively wide between the submerged end of the conveyor and the side wall of the tank, so that the aggregate is separated from the inclined conveyor and is easily discharged along the transfer screw with sludge such as soil powder, and the transfer screw may be damaged by the relatively large aggregate. There are also many.

In order to solve this problem, the submerged end of the conveyor may be configured to be close to the side wall of the tank, but in this case, the high pressure air sprayed in the water is blocked by the conveyor, which makes it difficult to lift the garbage. Can't. Of course, in this case, the high-pressure air may be injected from both sides of the tank, but this is also difficult to expect the easy floating effect of the garbage.

The present invention was devised to solve the above-mentioned conventional problems. The waste vinyl or waste wood mixed with the construction wastes is removed at the same time as it reliably removes foreign substances such as soil and cement powder contained in the recyclable aggregate in construction wastes. It is an object of the present invention to provide an aggregate washing apparatus of a construction waste regeneration treatment system capable of reliably separating and removing waste such as from aggregate.

Another object of the present invention is to aggregate the waste in the construction waste recycling system, which can easily float the waste on the water surface while restraining the floating injured garbage in the tank with the aggregate deeply submerged in the wash water to move to the exit of the conveyor. It is to provide a cleaning device.

Another object of the present invention is to prevent the aggregates introduced into the tank from falling off the conveyor and falling to the bottom of the tank, as well as being pushed along the stream of small aggregates being transported on the conveyor to discharge the floating garbage on the water surface. It is to provide an aggregate cleaning device of a construction waste recycling system that can effectively prevent the phenomenon.

According to one preferred feature of the present invention, the swinging unit is a rocking bed equipped with a soft mat having a predetermined elasticity in the frame of the frame is hinged to the side wall of the tank, and installed on the top of the tank and the rotating shaft A drive motor having an eccentric shaft and a link connecting the other end of the frame and the eccentric shaft of the motor so that the swinging bed is inclined properly in the opposite direction to the conveyor.

According to another preferred feature of the present invention, a plurality of flow path holes are formed in the soft mat of the swinging unit, and further comprising a floating water injection unit for spraying water at a high pressure toward the flow path hole under the soft mat. This makes the float floating more easily and at the same time improves the cleaning power of the aggregate.

According to another preferred feature of the present invention, by attaching the hook and the rubber plate alternately to the tip of each blade of the scraper, it is easy to discharge the floating floating on the water surface of the wash water.

Accordingly, the present invention can effectively clean the foreign matter such as soil powder on the aggregate while being able to reliably separate unnecessary waste such as waste vinyl mixed in the construction waste shred to the appropriate size from the recyclable aggregate.

In addition, as the waste put into the tank together with the aggregate is submerged deeply in the wash water, the movement of the waste to the exit of the conveyor is suppressed to the maximum, and the waste easily floats on the surface, and the aggregate is released from the conveyor or transported on the conveyor. It is also effectively prevented from being pushed in the moving direction of the garbage.

Therefore, the present invention has a great effect on improving the reliability and cleaning efficiency of the construction waste recycling system aggregate washing apparatus.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

2 to 4, the aggregate washing apparatus of the construction waste recycling treatment system according to the present invention is a water tank (10) filled with washing water, a conveyor 20 for transporting the washed aggregate (A) out of the water tank, 10) the oscillating unit 30, which bounces the injected aggregate A into the conveyor 20 and forms a vortex in the washing water, and drives the floating garbage W floating on the surface of the washing water to one side of the water tank 10. At the bottom of the scraper 50 and the bottom of the tank 10 for discharging the float floating blower 40 and the waste float W collected on one side of the tank 10 by the blower 40 out of the tank 10. It is configured to include a sludge discharge water injection unit 60 for discharging the sludge (S) such as precipitated soil powder out of the water tank (10).

The water tank 10 is configured to have one long rectangular shape, and the bottom 11 is configured to be inclined at an appropriate angle along the longitudinal direction. Preferably, the bottom 11 of the water tank 10 has an appropriate angle inward from each side wall of the water tank 10 so as to easily collect and discharge sludge S such as soil powder or cement powder removed from construction waste. It has a substantially gutter-shaped cross section consisting of two inclined portions 11a inclined downward and a relatively narrow flat portion 11b connecting the lower ends of these inclined portions 11a.

And a sludge discharge port for discharging the sludge (S) precipitated in the tank bottom 11 to the outside of the water tank 10 in the lower side of the side wall of the water tank 10 located on the lower side of the inclined bottom 11 of the water tank ( 12) is provided, the overflow groove 13 for discharging the floating waste (W) is formed to an appropriate depth.

Preferably, the overflow groove 13 of the side wall of the water tank 10 is provided with a overflow guide 14 having a substantially inverted V-shaped cross section for guiding the waste float W floating on the washing surface to be easily discharged to the outside. do.

Conveyor 20 is installed inclined along the bottom 11 in the interior of the water tank 10, most of which is immersed in the wash water, only the outlet end is exposed to the outside from one end of the water tank (10). The submerged portion of the conveyor 20 maintains a constant distance from the side wall of the water tank 10, both sides of the conveyor 20 to prevent the separation of the aggregate (A) and the aggregate (A) to be stable along the conveyor 20 Aggregate guides 21 for guiding to be transported are respectively located.

The swinging unit 30 is installed between the submerged stage of the conveyor 20 and the overflow guide 14 of the water tank 10. The swinging unit 30 includes a swinging bed 31 having one end positioned at the side of the conveyor 20 by hinge coupling on both sidewalls of the water tank 10, and a driving motor 34 for driving the swinging bed 31. And a link 35 connecting the rotary shaft of the drive motor 34 to the other end of the swinging bed 31.

As shown in FIG. 5, the swinging bed 31 is configured by mounting a soft mat 33 inside the frame 32 of the approximately frame type, preferably in a direction opposite to the inclination direction of the conveyor 20. It is inclined by the proper angle. This is to prevent the aggregates (A) of the construction waste introduced into the water tank 10 to be unnecessarily broken upon contact with the swinging bed 31 and to be easily bounced toward the conveyor 20.

Accordingly, it is preferable that the soft mat 33 be provided with appropriate elasticity and possess necessary strength, for example, made of hard rubber or urethane.

The free end of the swinging bed 31 is interposed between it and the overflow guide 14 of the tank 10 so as to prevent the garbage or aggregate A from leaking to the bottom of the tank 10 through a gap between them. The shield plate 37 is provided.

With such a configuration alone, the swirling bed 31 may form an appropriate vortex in the washing water to easily float the light-weight garbage mixed in the aggregate A. Preferably, a plurality of flow path holes are formed in the soft mat 33. 33a) to increase the flow of water by forming a stream of water upwards.

That is, the swinging bed 31 repeatedly performs a lever movement with respect to one end thereof, and when the swinging bed 31 descends, the washing water passes through each of the flow path holes 33a of the soft mat 33 and upwards. As the water flow is formed, the float floating water (W) is more easily floated on the water surface.

The flow path hole 33a of the soft mat 33 has a conical cross section whose diameter gradually decreases toward the upper surface for easy water flow generation.

On the other hand, more preferably, high-pressure water is sprayed upward toward the flow path hole 33a of the soft mat 33 in the inside of the water tank 10 to the lower side of the swing bed 31 so as to expedite the waste float W. It is further provided with a floating water injection unit 70 for inducing injury. The floating water injection unit 70 includes, for example, an injection pipe 71 having a plurality of nozzles 72 at regular intervals and connected to an external pressure pump (not shown). A plurality of injection pipes 71 are provided and arranged side by side at a predetermined interval.

The drive motor 34 is provided with an eccentric shaft 36 having a predetermined amount of eccentricity C on the rotation axis thereof so as to be rotatably connected to the upper end of the link 35 so as to repeatedly move the swinging bed 31. Preferably, the drive motor 34 is configured to be driven by an inverter (inverter) to adjust the number of revolutions to a predetermined range, for example, 0 ~ 60㎐ by adjusting the number of revolutions so that the garbage.

The float blower 40 is provided with a plurality and is arranged at regular intervals on the support plate 41 installed to cross the upper end of the water tank 10, and is installed as far as possible toward the exit end of the conveyor 20. This is to reliably prevent the fear that the garbage floating (W) is submerged to rise toward the outlet of the conveyor 20 to be discharged along the aggregate (A).

As shown in FIG. 6, the scraper 50 is rotatably installed in the overflow groove 13 of the water tank 10 by having a plurality of blades 52 radially around the rotation shaft 51. The scraper 50 is connected to an external power by a chain or the like, or directly connected to a motor (not shown) to be driven to rotate in a predetermined direction.

At the tip of each blade 52 of the scraper 50, a hook 53 and a rubber plate 54 are alternately attached to easily dispose of the garbage floating W collected on one side of the tank 10 out of the tank 10. do. The hook 53 has a width at which its tip can be rotated without interference by the overflow guide 14, while the rubber plate 54 is set to a width at which the tip can contact the overflow guide 14. As shown in FIG.

This means that although the hook 53 pulls the garbage float W out of the water tank 10, in the case of the small garbage float W, it may not be discharged by the clearance gap between the hook 53 and the overflow guide 14. This is for removing the remaining small garbage floats W reliably by rolling up the rubber plate 54 in contact with the overflow guide 14.

The sludge discharge water injection unit 60 is installed in the plane portion 11b of the gutter type tank bottom 11 at a predetermined interval along the inclined direction and includes a plurality of nozzles in two rows for injecting high pressure water toward the downward slope. Is done. These nozzles are piped to a pump (not shown) to spray sludge effluent.

At this time, the sludge discharge water may be continuously sprayed, but in this case, the sludge discharge port 12 of the water tank 10 must be opened at all times, so that the washing water is not excessively drained and wastewater is unnecessarily waste compared to the amount of sludge settled. Of course, the pump must also continue to run, which is undesirable.

Accordingly, an automatic valve 15 is installed at the sludge discharge port 12 of the water tank 10 to open and close the sludge discharge port 12 at predetermined time intervals, and the sludge discharge water injection unit 60 is interlocked with the automatic valve 15. It works intermittently.

On the other hand, near both ends of the water tank 10, the first for transporting the washed aggregate (A) discharged by the conveyor 20 and the waste suspended solids (W) discharged by the scraper 50, respectively, and transported to the subsequent process And second vibration dewatering screens 80 and 90 are respectively installed.

Next, the operation of the construction waste recycling system aggregate washing apparatus according to the present invention having such a structural feature will be described.

First, the construction waste in the state where the waste is first removed by the blower after being crushed to an appropriate size in the entire process of the construction waste recycling treatment system is transported by the conveyor 20 is introduced into the water tank (10). Then, the heavy aggregates (A) of the input construction waste sinks in the wash water and falls onto the swinging bed (31) of the swinging unit (30). Thus, the aggregates (A) settled above the swinging bed (31) lever up and down It is bounced by the swinging bed 31 which moves, and is blown onto the adjacent conveyor 20.

At this time, the swinging bed 31 is made of a soft mat 33, such as urethane having an appropriate elasticity, the upper surface is inclined toward the conveyor 20, so that unnecessary damage of the aggregate (A) during the impact is effectively prevented, of course, the aggregate (A) Are bounced off the conveyor 20 very easily and mounted on the conveyor 20.

In addition, the swinging bed 31 hits the aggregates A, and thus the aggregates A fly through the resistance of the water in the wash water, as well as the vortex in the wash water due to the lever movement of the swinging bed 31, so that the aggregates are aggregated. Foreign substances such as soil powder and cement powder which are buried in (A) are surely removed from the aggregate (A).

As such, the aggregates A mounted on the conveyor 20 move out of the water tank 10 along the conveyor 20 in a state in which foreign substances are removed, and are introduced into the first vibration dewatering screen 80, where the dehydration treatment is performed. It is then transferred to subsequent processes.

On the other hand, light waste suspended solids (W) such as waste vinyl or waste plastic mixed into the aggregate (A) and introduced into the water tank (10) are suspended directly on the water surface by buoyancy of the washing water according to its specific gravity or washed water along the aggregate (A). After submerged in the water surface, the floating floating water (W) submerged in the wash water in this way is also easily floated on the water surface by the vortex generated by the swinging unit (30).

That is, since the swinging bed 31 of the swinging unit 30 moves up and down, the vortices are generated in the washing water in the up and down direction, and the floating float W submerged along the aggregate A is easily injured. In particular, since the aggregate A and the waste float W cannot be deeply submerged in the water tank 10 by the swinging bed 31, the waste float W is submerged and moved toward the exit end of the conveyor 20. Rarely occurs.

In addition, a plurality of flow path holes 33a are formed in the soft mat 33 of the swinging bed 31, so that water flow is generated upward by each flow path hole 33a during the lever movement. High pressure water is injected upward from the nozzles 72 of the floating water injection unit 70 installed in the lower part, and the water sprayed in this way swings the bed through each of the flow path holes 33a of the soft mat 33. A strong water stream in the form of a jet is formed at the upper part of 31 so as to quickly float the garbage float W upwards.

Therefore, the phenomenon that the floating waste W (submerged in the wash water) is moved toward the outlet of the conveyor 20 is effectively suppressed.

And, the floating waste W (floating) on the water surface is installed on one upper end of the water tank (10) by the plurality of float transport blowers 40 for blowing air on the water surface grooves 13 of the water tank (10) Move toward) and gather.

At this time, the wind discharged from the float transporting blower 40 causes a gentle flow on the water surface to push the floating waste floating material (W), since the strong water flow is not generated by high-pressure water injection as in the conventional conveyor The phenomenon in which the small aggregate (A) being transported on (20) is pushed out by the water flow for discharging the garbage float (W) is also effectively prevented.

The garbage float W moved near the overflow groove 13 of the water tank 10 by the float transport blower 40 is along the overflow guide 14 by the scraper 50 rotated in the overflow flow groove 13. The second vibration dewatering screen 90 is discharged. At this time, since the scraper 50 alternately attaches the hook 53 and the rubber plate 54 to the blade 52, the scraper 50 is discharged very easily and reliably.

That is, as the scraper 50 rotates, the hook 53 lifts and discharges the floating garbage W floating on the water surface, and then the rubber plate 54 contacts the overflow guide 14 and scrapes the small garbage float. It is possible to reliably discharge to (W).

On the other hand, the foreign matter separated from the aggregate (A) and the garbage floating (W) is sinked to the bottom 11 of the tank 10, the bottom 11 of the tank of the present invention is composed of both sides of the inclined portion (11a). Since the sludge S is easily collected. As such, the sludge S accumulated on the flat portion 11b of the tank bottom 11 is pushed downward by the sludge discharge water injection unit 60 installed on the tank bottom 11 to intermittently spray high pressure water. It is discharged to the outside through the sludge discharge port 12 of the water tank (10).

That is, the sludge discharge port 12 has an automatic valve 15 attached to open and close the sludge discharge port 12 at predetermined time intervals, and the sludge discharge water injection unit 60 does not operate while the automatic valve 15 is closed. Sludge (S) is accumulated on the bottom 11 of the water tank 10, when the automatic valve 15 is opened after a certain time passes the sludge discharge water injection unit 60 is activated to spray the high pressure water down the slope. As a result, the sludge S is slid along the inclined surface of the tank bottom 11 to be discharged to the outside through the sludge outlet 12.

In addition, the washing apparatus of the present invention is blocked between the side wall of the water tank 10 and the conveyor 20 by the swinging bed 31, the injected aggregate (A) is separated from the conveyor 20 to the bottom of the water tank 10 ( There is little fear that it will not go away.

As described above, according to the aggregate washing apparatus of the construction waste recycling system according to the present invention, it is possible to reliably separate unnecessary waste such as waste vinyl mixed with construction waste shredded to an appropriate size from the aggregate that can be recycled. Effectively cleans foreign substances such as soil powder.

In addition, as the waste put into the tank together with the aggregate is submerged deeply in the wash water, the movement of the waste to the exit of the conveyor is suppressed to the maximum, and the waste easily floats on the surface, and the aggregate is released from the conveyor or transported on the conveyor. It is also effectively prevented from being pushed in the moving direction of the garbage.

Therefore, the present invention has a very excellent effect of greatly improving the reliability and cleaning efficiency of the construction waste recycling treatment system aggregate washing apparatus.
