Description

Technical Field

[0001] The present invention relates to the technical field of manure treatment, and in particular to a pretreatment separation device for livestock manure and a pretreatment method thereof. Background Art

[0002] Aquaculture wastewater mainly refers to wastewater generated within the scope of the breeding farm, namely, farm manure when flushing livestock / poultry houses, residual feed and medicine mixed water, and domestic sewage generated by employees in the breeding farm. Aquaculture wastewater has pollution characteristics such as high suspended matter, high concentration of organic matter and ammonia nitrogen, strong odor and rich in certain heavy metals. It also has the characteristics of complex water quality, scattered discharge points, and difficulty in collection and treatment.

[0003] When pre-treating and separating manure and sewage, the manure and sewage may surge upward after being squeezed. If there is no top pressure constraint, the liquid in the manure and sewage cannot be fully squeezed out, which will cause some of the liquid that could have been separated to remain in the solid, resulting in incomplete solid-liquid separation. To address the above problems, the following solutions are proposed. Summary of the invention

When the separation is completed, the driving motor is started to drive the bidirectional threaded rod to rotate in the opposite direction, so as to drive the two extrusion plates away from each other. When the two extrusion plates move away from each other, the sealing plate 1 is driven to slide in the movable groove 2 through the connecting rod, so that the sealing plate 1 blocks the air inlet groove, and when the two extrusion plates move away from each other, the extrusion plate drives the sealing plate 2 to slide in the movable groove 3 through the circular rod, so that the sealing plate 2 blocks the drainage groove.

[0009] Preferably, the anti-blocking mechanism also includes a plurality of fixed rods fixedly connected to the inner wall of the shell body, the plurality of fixed rods all penetrate the corresponding extrusion plates and are slidably connected to the corresponding extrusion plates, the outer walls of the plurality of fixed rods are rotatably connected with strip blocks, the side walls of the extrusion plates are fixedly connected with two guide rails, the outer walls of the two guide rails are slidably connected with scrapers, the side walls of the scrapers are rotatably connected with the strip blocks, after the feces and sewage in the through hole are blown out, the blown feces and sewage may remain on the side walls of the extrusion plates, before the two extrusion plates move away from each other, the scrapers are located at the bottom of the guide rails, and as the two extrusion plates move closer to each other, the scrapers are affected by the strip blocks The limitation of will drive the scraper to move upward along the outer wall of the guide rail, and the scraper can scrape off the feces and dirt remaining on the side wall of the extrusion plate after moving upward. If the residual feces and dirt are not cleaned up, they may be mixed into the feces and dirt to be processed again in the subsequent separation operation, affecting the accuracy and efficiency of solid-liquid separation. Cleaning the residual feces and dirt can ensure the consistency and reliability of each separation process and ensure the stability of the separation effect. By timely cleaning the residual feces and dirt on the side wall of the extrusion plate, these residual materials can be prevented from being mixed into the feces and dirt again in the subsequent separation operation, thereby ensuring that the liquid and solid can be separated more accurately in the solid-liquid separation process and improving the separation efficiency.

[0010] Preferably, the cleaning mechanism also includes a mounting plate fixedly connected to the bottom of the supporting plate, a return spring fixedly connected to the side wall of the special-shaped plate, an end of the return spring away from the special-shaped plate is fixedly connected to the mounting plate, the inner wall of the shell is fixedly connected to the fixing plate, the side wall of the fixing plate is slidably connected to a sliding rod, the sliding rod penetrates the fixing plate and is slidably connected to the fixing plate, the left end of the sliding rod is fixedly connected to a circular plate, the side of the circular plate and the fixing plate close to each other is fixedly connected to a storage spring, the end of the sliding rod away from the circular plate is fixedly connected to a striking rod, and the outer wall of the striking rod is fixedly connected to a striking block, which is restricted by the inclined surface of the special-shaped plate. As the two special-shaped plates move to the middle position, the inclined surface of the special-shaped plate contacts the striking block, forcing the special-shaped plate to rotate with the rotating rod as the midpoint. At this time, the return spring is subjected to an extrusion force. When the special-shaped plate passes through the striking block, the inclined surface of the special-shaped plate no longer contacts the striking block. At this time, the return spring is squeezed The force disappears, driving the special-shaped plates to complete reset. After the two extrusion plates complete the extrusion and separation of the feces and sewage, the two extrusion plates move away from each other. When the extrusion plate moves outward, it drives the two special-shaped plates to move outward. At this time, the two special-shaped plates pull the impact block and the impact rod to move outward. When the impact rod moves outward, an extrusion force is applied to the force storage spring. As the extrusion plate continues to move outward, it can drive the two special-shaped plates to contact the V-shaped stopper. The two special-shaped plates are blocked by the V-shaped stopper, forcing the special-shaped plates to rotate with the rotating rod as the midpoint. After the special-shaped plate rotates, it no longer pulls the impact block. At the same time, the extrusion force on the force storage spring disappears, thereby driving the impact block to hit the extrusion plate. After the extrusion plate is hit, the impact force on the extrusion plate is transmitted to the scraper. The feces and sewage adsorbed on the extrusion plate and the scraper are cleaned up through the impact force generated by the collision, thereby achieving comprehensive cleaning of feces and sewage residues and reducing the possibility of feces and sewage residues.

[0011] A pretreatment method of a livestock manure pretreatment separation device comprises the following steps: S1: When the feces and sewage need to be pre-processed and separated, the valve of the discharge pipe is first closed, and then the drive motor is started. The drive motor drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod rotates to drive the two extrusion plates to move closer to each other; S2: When the two extrusion plates move away from each other, the sealing plate 1 drives the sealing plate 1 to slide in the movable groove 2 through the connecting rod, so that the sealing plate 1 blocks the air inlet groove; S3: As the two extrusion plates approach each other, the scraper is restricted by the strip block, which drives the scraper to move upward along the outer wall of the guide rail. After the scraper moves upward, it can scrape off the feces and dirt remaining on the side wall of the extrusion plate; S4: The impact block impacts the extrusion plate. After the extrusion plate is impacted, the impact force received by the extrusion plate is transmitted to the scraper. The impact force generated by the impact cleans up the feces and dirt adsorbed on the extrusion plate and the scraper.

[0012] The present invention has the following beneficial effects: When the present invention needs to pre-treat and separate the feces and sewage, first close the valve of the discharge pipe, and then start the driving motor, which drives the two-way threaded rod to rotate. After the two-way threaded rod rotates, it drives the two extrusion plates to approach each other. When the two extrusion plates approach each other, they are limited by the limiting block, which can ensure the stability of the two-way threaded rod when driving the two extrusion plates to approach each other. When the two extrusion plates approach each other and completely pass through the drainage trough, the two-way threaded rod stops rotating. At this time, the feces and sewage to be processed are transported to between the two extrusion plates through the feed pipe. After the feces and sewage are transported, the two-way threaded rod rotates again to drive the two extrusion plates to continue to approach each other. As the two extrusion plates continue to approach each other, the two extrusion plates transported to the two extrusion plates can be The manure and sewage are squeezed between the two squeezing plates. By squeezing the manure and sewage, the liquid in the manure and sewage flows out through a number of through holes, while the solid in the manure and sewage remains between the two squeezing plates. When the two squeezing plates are close to each other to squeeze the manure and sewage, the manure and sewage are squeezed to move upward. At this time, the squeezing plate drives the fixed block to move in the direction of the feed pipe, forcing the slide plate to slide in the movable groove one, and then squeezes the gas in the movable groove one to expand the telescopic tube, driving the arc-shaped slide block one and the arc-shaped slide block two to move downward, applying downward pressure on the top of the manure and sewage, and combining with the squeezing of the two sides of the manure and sewage by the squeezing plate, the liquid in the manure and sewage can be separated from the manure and sewage more effectively, thereby improving the separation effect and providing better conditions for subsequent manure and sewage treatment links.

[0013] When the separation is completed, the present invention starts the driving motor to drive the bidirectional threaded rod to rotate in the opposite direction, so as to drive the two extrusion plates to move away from each other. When the two extrusion plates move away from each other, the sealing plate one drives the sliding plate two in the movable groove two through the connecting rod, so that the sealing plate one blocks the air inlet groove. When the two extrusion plates move away from each other, the extrusion plate drives the sealing plate two to slide in the movable groove three through the circular rod, so that the sealing plate two blocks the drainage groove. By blocking the air inlet groove and the drainage groove, when the two extrusion plates move away from each other, the gas between the shell and the extrusion plates can be squeezed, and the squeezed gas can be blown to a plurality of through holes. When the arc-shaped slider one and the arc-shaped slider two squeeze the feces and dirt downward, the feces and dirt will block a plurality of through holes. The squeezed gas is blown to the through holes, and the feces and dirt that block the through holes when the arc-shaped slider one and the arc-shaped slider two squeeze the feces and dirt downward can be blown out, so as to effectively keep the through holes unobstructed, ensure that the liquid can flow out smoothly through the through holes in the next feces and dirt separation process, and timely clean the feces and dirt that block the through holes, so as to ensure that each separation process can achieve a better solid-liquid separation effect, and ensure the stability of the separation effect.

[0014] After the present invention blows out the feces and sewage in the through hole, the blown feces and sewage may remain on the side walls of the extrusion plate. Before the two extrusion plates move away from each other, the scraper is located at the bottom of the guide rail. As the two extrusion plates approach each other, the scraper is restricted by the strip block, which drives the scraper to move upward along the outer wall of the guide rail. After the scraper moves upward, the feces and sewage remaining on the side walls of the extrusion plate can be scraped off. If the residual feces and sewage are not cleaned up, they may be mixed into the feces and sewage to be processed again in the subsequent separation operation, affecting the accuracy and efficiency of solid-liquid separation. Cleaning the residual feces and sewage can ensure the consistency and reliability of each separation process and ensure the stability of the separation effect. By timely cleaning the residual feces and sewage on the side walls of the extrusion plate, it is possible to prevent these residual substances from being mixed into the feces and sewage again in the subsequent separation operation, thereby ensuring that the liquid and solid can be separated more accurately in the solid-liquid separation process and improving the separation efficiency.

[0015] After the scraper of the present invention scrapes off the residual feces and sewage, the feces and sewage may be adsorbed on the scraper. When the two extrusion plates approach each other, the extrusion plate drives the sealing plate one to move to the middle position through the connecting rod, and then the sealing plate one drives the two special-shaped plates to move to the middle position through the supporting plate. Restricted by the inclined surfaces of the special-shaped plates, as the two special-shaped plates move to the middle position, the inclined surfaces of the special-shaped plates contact the impact blocks, forcing the special-shaped plates to rotate with the rotating rod as the midpoint. At this time, the reset spring is subjected to an extrusion force. When the special-shaped plates pass through the impact blocks, the inclined surfaces of the special-shaped plates no longer contact the impact blocks. At this time, the extrusion force exerted on the reset spring disappears, driving the special-shaped plates to complete the reset. After the two extrusion plates complete the extrusion and separation of the feces and sewage, the two extrusion plates move away from each other. The extrusion plates move outward. When the extrusion plate moves, it drives the two special-shaped plates to move outward. At this time, the two special-shaped plates pull the impact block and the impact rod to move outward. When the impact rod moves outward, an extrusion force is applied to the force storage spring. As the extrusion plate continues to move outward, it can drive the two special-shaped plates to contact the V-shaped block. The two special-shaped plates are blocked by the V-shaped block, forcing the special-shaped plates to rotate with the rotating rod as the midpoint. After the special-shaped plates rotate, they no longer pull the impact block. At the same time, the extrusion force on the force storage spring disappears, thereby driving the impact block to hit the extrusion plate. After the extrusion plate is hit, the impact force on the extrusion plate is transmitted to the scraper. The impact force generated by the impact cleans up the feces and dirt adsorbed on the extrusion plate and the scraper, thereby achieving comprehensive cleaning of feces and dirt residues and reducing the possibility of feces and dirt residues.

Restricted by the inclined surface of the special-shaped plate 303, as the two special-shaped plates 303 move to the middle position, the inclined surface of the special-shaped plate 303 contacts the impact block 311, forcing the special-shaped plate 303 to rotate with the rotating rod 302 as the midpoint. At this time, the return spring 305 is subjected to an extrusion force. When the special-shaped plate 303 passes through the impact block 311, the inclined surface of the special-shaped plate 303 no longer contacts the impact block 311. When the two extrusion plates 108 are pressed and separated, the two extrusion plates 108 move away from each other. When the extrusion plates 108 move outward, the two extrusion plates 303 move outward. At this time, the two extrusion plates 303 pull the impact block 311 and the impact rod 310 to move outward. When the impact rod 310 moves outward, an extrusion force is applied to the force storage spring 309. As the extrusion plates 108 continue to move outward, the two extrusion plates 303 can be driven to contact the V-shaped stopper 33. The V-shaped stopper 33 blocks the special-shaped plate 303, forcing it to rotate with the rotating rod 302 as the midpoint. After the special-shaped plate 303 rotates, it no longer pulls the impact block 311. At the same time, the extrusion force exerted on the force storage spring 309 also disappears, thereby driving the impact block 311 to impact the extrusion plate 108. After the extrusion plate 108 is impacted, the impact force exerted on the extrusion plate 108 is transmitted to the scraper 213. The impact force generated by the impact cleans up the feces and dirt adsorbed on the extrusion plate 108 and the scraper 213, thereby achieving comprehensive cleaning of the feces and dirt residues and reducing the possibility of feces and dirt residues.

[0027] The pretreatment method of the pretreatment separation device comprises the following steps: S1: When the feces and sewage need to be pre-processed and separated, the valve of the discharge pipe 104 is first closed, and then the drive motor 106 is started, and the drive motor 106 drives the bidirectional threaded rod 109 to rotate, and the bidirectional threaded rod 109 rotates to drive the two extrusion plates 108 to move closer to each other; S2: When the two extrusion plates 108 move away from each other, the sealing plate 1 203 is driven to slide in the movable groove 2 202 through the connecting rod 204, so that the sealing plate 1 203 blocks the air inlet groove 201; S3: As the two extrusion plates 108 approach each other, the scraper 213 is restricted by the strip block 211, which drives the scraper 213 to move upward along the outer wall of the guide rail 212. After the scraper 213 moves upward, it can scrape off the feces and dirt remaining on the side wall of the extrusion plate 108; S4: The impact block 311 impacts the extrusion plate 108. After the extrusion plate 108 is impacted, the impact force exerted on the extrusion plate 108 is transmitted to the scraper 213. The excrement and dirt adsorbed on the extrusion plate 108 and the scraper 213 are cleaned away by the impact force generated by the impact.

[0028] A specific application of this embodiment is: When it is necessary to pre-treat and separate the feces and sewage, first close the valve of the discharge pipe 104, then start the drive motor 106, and the drive motor 106 drives the two-way threaded rod 109 to rotate. After the two-way threaded rod 109 rotates, it drives the two extrusion plates 108 to approach each other. When the two extrusion plates 108 approach each other, they are limited by the limit block 107, which can ensure the stability of the two-way threaded rod 109 when driving the two extrusion plates 108 to approach each other. When the two extrusion plates 108 approach each other and completely pass through the drainage trough 205, the two-way threaded rod 109 stops rotating. At this time, the feces and sewage to be processed are transported to between the two extrusion plates 108 through the feed pipe 111. After the feces and sewage are transported, the two-way threaded rod 109 rotates again to drive the two extrusion plates 108 to continue to approach each other. As the two extrusion plates 108 continue to approach each other, they can The feces and sewage transported between the two squeezing plates 108 are squeezed. By squeezing the feces and sewage, the liquid in the feces and sewage flows out through the plurality of through holes 110, while the solids in the feces and sewage remain between the two squeezing plates 108. When the two squeezing plates 108 are close to each other to squeeze the feces and sewage, the feces and sewage are squeezed and move upward. At this time, the squeezing plate 108 drives the fixed block 113 to move in the direction of the feeding pipe 111, forcing the slide plate 115 to slide in the movable groove 114, thereby squeezing the gas in the movable groove 114 to expand the telescopic tube 119, driving the arc slider 116 and the arc slider 2 117 to move downward, applying downward pressure on the top of the feces and sewage, and combining with the squeezing of the two sides of the feces and sewage by the squeezing plate 108, the liquid in the feces and sewage can be separated from the feces and sewage more effectively, thereby improving the separation effect and providing better conditions for the subsequent feces and sewage treatment links.

[0029] When the separation is completed, the valve 104 is opened, and the solids in the feces are discharged from 104. Then the driving motor 106 is started to drive the bidirectional threaded rod 109 to rotate in the opposite direction, so as to drive the two extrusion plates 108 to move away from each other. When the two extrusion plates 108 move away from each other, the sealing plate 1 203 is driven to slide in the movable groove 202 through the connecting rod 204, so that the sealing plate 1 203 blocks the air inlet groove 201. When the two extrusion plates 108 move away from each other, the extrusion plate 108 drives the sealing plate 207 to slide in the movable groove 3 206 through the circular rod 208, so that the sealing plate 207 blocks the drainage groove 205. By blocking the air inlet groove 201 and the drainage groove 205, when the two extrusion plates 108 move away from each other, the sealing plate 207 is driven to slide in the movable groove 3 206 through the circular rod 208, so that the sealing plate 207 blocks the drainage groove 205. When far away, the gas between the shell 101 and the extrusion plate 108 can be squeezed, and the squeezed gas can be blown to several through holes 110. When the arc-shaped slider 116 and the arc-shaped slider 2 117 squeeze the feces and dirt downward, the feces and dirt will block several through holes 110. The squeezed gas is blown to the through holes 110, and the feces and dirt that block the through holes 110 when the arc-shaped slider 116 and the arc-shaped slider 2 117 squeeze the feces and dirt downward can be blown out, thereby effectively keeping the through holes 110 unobstructed, ensuring that the liquid can flow out through the through holes 110 smoothly during the next feces and dirt separation process, and promptly cleaning the feces and dirt that block the through holes 110, ensuring that each separation process can achieve a better solid-liquid separation effect, and ensuring the stability of the separation effect.

[0030] After the excrement in the through hole 110 is blown out, the blown excrement may remain on the side wall of the extrusion plate 108. Before the two extrusion plates 108 move away from each other, the scraper 213 is located at the bottom of the guide rail 212. As the two extrusion plates 108 approach each other, the scraper 213 is restricted by the strip block 211, which will drive the scraper 213 to move upward along the outer wall of the guide rail 212. After the scraper 213 moves upward, the excrement remaining on the side wall of the extrusion plate 108 can be scraped off. If the residual excrement is not cleaned, it may be mixed into the excrement to be processed again in the subsequent separation operation, affecting the accuracy and efficiency of solid-liquid separation. Cleaning the residual excrement can ensure the consistency and reliability of each separation process and ensure the stability of the separation effect. By timely cleaning the residual excrement on the side wall of the extrusion plate, it can be avoided that these residual materials are mixed into the excrement again in the subsequent separation operation, thereby ensuring that the liquid and solid can be separated more accurately during the solid-liquid separation process and improving the separation efficiency.

[0031] After the scraper 213 scrapes off the residual feces and dirt, the feces and dirt may be adsorbed on the scraper 213. When the two extrusion plates 108 approach each other, the extrusion plate 108 drives the sealing plate 203 to move to the middle position through the connecting rod 204, and then the sealing plate 203 drives the two special-shaped plates 303 to move to the middle position through the supporting plate 301. Restricted by the inclined surface of the special-shaped plate 303, as the two special-shaped plates 303 move to the middle position, the inclined surface of the special-shaped plate 303 contacts the impact block 311, forcing the special-shaped plate 303 to rotate with the rotating rod 302 as the midpoint. At this time, the reset spring 305 is subjected to an extrusion force. When the special-shaped plate 303 passes through the impact block 311, the inclined surface of the special-shaped plate 303 no longer contacts the impact block 311. At this time, the extrusion force exerted on the reset spring 305 disappears, driving the special-shaped plate 303 to complete the reset. After the two extrusion plates 108 complete the extrusion and separation of the feces and dirt, the two extrusion plates 108 move away from each other. The extrusion plates 108 move toward When the cam 310 is in the state of being moved outward, the two shaped plates 303 are driven to move outward. At this time, the two shaped plates 303 pull the impact block 311 and the impact rod 310 to move outward. When the impact rod 310 moves outward, an extrusion force is applied to the force storage spring 309. As the extrusion plate 108 continues to move outward, the two shaped plates 303 can be driven to contact the V-shaped stopper 33. The two shaped plates 303 are blocked by the V-shaped stopper 33, forcing the shaped plates 303 to rotate with the rotating rod 302 as the midpoint. After the shaped plates 303 rotate, they no longer pull the impact block 311. At the same time, the extrusion force exerted on the force storage spring 309 disappears, thereby driving the impact block 311 to impact the extrusion plate 108. After the extrusion plate 108 is impacted, the impact force exerted on the extrusion plate 108 is transmitted to the scraper 213. The impact force generated by the impact is used to clean up the feces and dirt adsorbed on the extrusion plate 108 and the scraper 213, thereby achieving comprehensive cleaning of the feces and dirt residues and reducing the possibility of feces and dirt residues.
