The material with low moisture content of about 60% can be obtained by secondary extrusion and dehydration. In this way, not only the energy consumption of the dehydration process is large, but also the production efficiency of the primary and secondary solid-liquid separators is not easy to match. It is necessary to continuously adjust the operating speed of the two-stage equipment by the operator or use the automatic detection system for automatic coordination, but in any case, this Both increase the cost of equipment and the probability of equipment failure in the production process.

Embodiment 1: This embodiment is described with reference to FIG. 1 to FIG. 5 . The screw-propelled high-pressure solid-liquid separator described in this embodiment includes a feed port 1, an overflow port 2, a buffer chamber 3, a blocking baffle 8, an adjusting screw 10, a screen 11, a liquid collecting tank 12, and a driving device , the screw extrusion push rod 15, the protective cover 16, the liquid discharge port 18, the screen reinforcement frame 20, the front end clamping structure 22 and a number of replaceable articulated bushings 13; the protective cover 16 is longitudinally installed with a screw extrusion Propulsion rod 15, a screen 11 is installed on the outer periphery of the screw extrusion rod 15, and the screen 11 is fixedly connected with the protective cover 16 through the screen reinforcement frame 20. The screw extrusion push rod 15 rotates, and the other end is provided with a discharge port. The front end of the discharge port is fixed with a blocking baffle 8 through the adjustment screw 10. The screw extrusion push rod 15 is divided into two discontinuous sections. , respectively the primary extrusion section and the secondary extrusion section, a buffer chamber 3 is installed above the left side of the protective cover 16 , and a feed port 1 and an overflow port 2 are installed on the buffer chamber 3 . A leak hole is provided at the bottom of the cover 16 , a liquid collecting tank 12 is installed under the protective cover 16 , and a liquid discharge port 18 is provided under the liquid collecting tank 12 ; There are several replaceable articulated bushings 13, the secondary extrusion section of the screw extrusion push rod 15 and several replaceable articulated bushings 13 can be removed from the through shaft 21 and changed positions, the screw extrusion The front end through shaft 21 of the push rod 15 protrudes from the protective cover 16 and a front end clamping structure 22 is installed at the end to fasten the secondary extrusion section of the screw extrusion push rod 15 and several replaceable articulated bushings 13 . Where there is a spiral extrusion rod 15, a screen 11 is set close to the outside of the blade, and the extruded waste liquid enters the liquid collecting tank 12 through the screen 11 and is discharged through the liquid discharge port 18.

The protective cover 16 is longitudinally divided into a feeding zone 4, a preliminary extrusion zone 5, a spacing zone 6, a secondary extrusion zone 7 and a discharge zone 9. The preliminary extrusion section of the screw extrusion push rod 15 It is located in the primary extrusion zone 5, and the secondary extrusion section is located in the secondary extrusion zone 7.

The outer diameter of the screw extruding rod 15 is 350-450 mm, the diameter of the through shaft 21 (that is, the outer diameter of the screw) is 150-250 mm, the propulsion blade is a single helix, and the rising angle of the screw extruding rod 15 is 150-250 mm. 5 to 16 degrees.

The length of the primary extrusion section and the secondary extrusion section of the screw extrusion push rod 15 is 500-900 mm, and the length of the discharge area 9 is 200-400 mm.

The front-end clamping structure 22 includes a fixing plate and several screws, and the fixing plate is fixed on the end of the through shaft by several screws.

The gist of the present invention is to divide the helical blades on the helical extrusion push rod 15 into two discontinuous structures, namely the primary extrusion section and the secondary extrusion section. In the secondary extrusion zone 7, the helical blade pitch of the primary extrusion section is relatively large, and the helical blade pitch of the secondary extrusion section is relatively small. The accumulation process can make the material with high moisture content get preliminary solid-liquid separation.

When the material is advanced to the secondary extrusion zone 7, because the pitch of the helical blades of the secondary extrusion section is smaller, the material advancing speed is slower, so that the material is disconnected between the primary extrusion and the secondary extrusion blade. The distance between them is further compressed, so that we can expect to obtain materials with a moisture content of about 70%, which basically achieves the function of a solid-liquid separator.

After the one-step extrusion, the volume-compressed material enters the secondary extrusion zone 7. Since the propulsion speed of the spiral blades in the secondary extrusion section is small, but the thrust is large, the extrusion force can be further applied to the material. After the material is pushed to the discharge area 9, due to the action of the blocking baffle 8 at the front end of the discharge port 9, the extrusion force on the material is further increased, and the moisture in the material is further passed through the screen of the discharge area 9. discharge.

However, it is very critical how much the broken length of the primary and secondary helical blades (ie the spacer 6) can just make the moisture content of the final material reach the desired level. Therefore, in this case, a variable blade spacing bushing is designed on the screw extrusion push rod 15, and several sections of replaceable articulated bushings 13 with the same inner diameter as the screw blades of different lengths are sleeved on the through shaft 21. The relative position of the joint shaft sleeve 13 and the two sections of the helical blades can be replaced to change the distance of the interval area 6 until a material with a satisfactory moisture content is obtained, and the final moisture content of the material is controlled between 50% and 60%.

The operating principle of adjusting the spacing of the spacer 6 is as follows: the helical blades located in the secondary extrusion area 7 are disconnected from the helical blades located in the primary extrusion area 5, they are simultaneously sleeved on a through shaft 21, and at the same time a number of short can be The replacement articulated shaft sleeve 13 is also sleeved on the through shaft 21, the helical blade of the secondary extrusion area 7 can be removed from the through shaft 21, and then the replaceable articulated shaft sleeve 13 between the interval areas 6 can be increased or decreased. This changes the pitch of the spacers 6 . The replaceable hinged sleeve 13 removed from the spacer 6 is fixed at the front end (discharge port end) of the helical blade through the front-end clamping structure 22, so that the blade sleeved on the through shaft 21 and the replaceable hinged The sum of the connecting shaft sleeves 13 has not changed; when the spacing of the spacer area 6 is to be increased, the replaceable joint shaft sleeve 13 at the front end of the blade in the secondary extrusion area 7 is removed together, and then the front end can be replaced. The shaft sleeve 13 is sleeved on the through shaft 21 first, and then the secondary extrusion section of the helical blade 15 is sleeved, so that the distance of the interval 6 is increased, and the helical blade 15 sleeved on the through shaft 21 at this time and can be The total number and length of the replacement union bushings 13 remain unchanged.

The screen reinforcement frame 20 includes an upper screen reinforcement structure and a lower screen reinforcement structure. The upper screen reinforcement structure and the lower screen reinforcement structure have the same structure and are semi-cylindrical structures. The upper screen reinforcement structure is installed. A cylindrical structure is formed above the lower screen reinforcement structure; the screen 11 is divided into upper and lower halves, which are respectively installed on the inner surfaces of the upper screen reinforcement structure and the lower screen reinforcement structure, and the upper screen reinforcement structure includes several reinforcement Ring rib 201, several reinforcement longitudinal ribs 202, two end flanges 203, two longitudinal flanges 204 and reinforcement orifice plate 205, the screen 11 is installed on the inner surface of the upper screen reinforcement structure, the screen 11 A reinforcing orifice plate 205 is installed on the outer periphery, and many small holes are distributed on the screen 11 and the reinforcing orifice plate 205. The outer periphery of the reinforcing orifice plate 205 is longitudinally installed with a number of reinforcement longitudinal ribs 202, and transversely installed with a number of reinforcement ring ribs 201 , End flanges 203 are installed at both ends of several of the reinforcing longitudinal ribs 202, and longitudinal flanges 204 are installed at both ends of several of the reinforcing ring ribs 201. The upper screen reinforcement structure and the lower screen reinforcement structure pass through the longitudinal direction. The flange 204 is fixedly connected.

The reinforcing orifice plate 205 is in close contact with the outer surface of the screen mesh 11 . The aperture of the small holes on the screen mesh 11 is 2.5-3.5mm, the mesh wall thickness is 2-4mm, and the hole spacing is 4-7mm. The thickness of the reinforcing orifice plate 205 is 5-15 mm. The diameter of the small holes on the reinforcing orifice plate 205 is 25-30mm, and the hole spacing is 35-40mm.

The water extruded by the screw extruding rod 15 exerts high pressure on the material and is discharged through the screen, and the screen is also subjected to the pressure exerted by the screw extruding rod 15 through the material while the water is discharged. The structure does not have enough strength and rigidity to resist this kind of pressure, on the one hand, it cannot play the role of separating moisture well, and on the other hand, it cannot work well for a long time because of the total damage. In order to solve the problem that the screen structure in the prior art does not have sufficient strength and rigidity to resist pressure, the present invention designs a screen reinforcement frame 20 applied to the high-pressure solid-liquid separation equipment.

The screen reinforcement frame applied to the high-pressure solid-liquid separation equipment is a cylindrical structure, and the outer reinforcement cylindrical structure with densely clothed large holes is close to the secondary screen 11, and several strips are closely arranged on the outside. Longitudinal annular rib. For convenience of disassembly and maintenance, the secondary screen is divided into two semi-cylindrical secondary screens 11 in the circumferential direction, and the outer reinforced cylindrical structure is equally divided into two reinforced orifice plates 205 .

The specific operation process and working principle of the screw-propelled high-pressure solid-liquid separator of the present invention are as follows:

The drive motor 18 drives the reducer 17 to rotate, and the reducer 17 drives the screw extrusion push rod 15 to rotate. The manure mixed material enters the buffer chamber 3 from the feed port 1, and the excess material returns to the manure tank from the overflow port 2 to buffer. The material in the chamber 3 enters the feeding area 4 and then pushes forward to the primary extrusion area 5 through the screw extrusion push rod 15. After the initial pressure, the material is pushed to the interval area 6. When the material is advanced to the secondary extrusion area 7 , because the pitch of the helical blades of the secondary extrusion section is smaller, the speed of material advancement is slower, so that the material is further compressed in the interval area 6 to obtain a material with a moisture content of about 70%, and the material passes through the secondary extrusion area 7. It is pushed into the bladeless discharge area 9 with a larger extrusion force, and is extruded after reaching the discharge port 10 under the action of the shaft end blocking baffle 8. After the secondary extrusion, the moisture content of the material decreases to 50 to 55%. In the whole extrusion process, the organic finely crushed materials with a moisture content greater than 80% can be squeezed and dehydrated by one device to reduce the moisture content to 50-55%, the extrusion process is smooth, and the energy consumption is low.

The specific embodiments described above further describe the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above descriptions are only specific embodiments of the present invention, and are not intended to limit the present invention, and may also be a reasonable combination of the features recorded in the above-mentioned various embodiments, all within the spirit and principle of the present invention, Any modification, equivalent replacement, improvement, etc. made should be included within the protection scope of the present invention.
