Description

Technical Field

[0001] This invention relates to the technical field of solid-liquid separation equipment for processing waste, specifically to a solid-liquid separation device and separation method for processing waste. Background Technology

[0002] Processing waste refers to substances generated during various processing and production processes that no longer have their original use value and are discarded or planned to be discarded. Its specific meaning and scope vary depending on the processing industry and the type of raw materials. Common types include food processing waste, agricultural product processing waste, industrial processing waste, and metal processing scraps.

[0003] An existing solid-liquid separation device for processing waste cannot squeeze the waste during the separation process to ensure complete separation. Furthermore, manual cleaning of the filter screen is usually required during the separation process, and the device cannot be automatically cleaned during the separation process, which reduces the machine's efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a solid-liquid separation device and method for processing waste, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a solid-liquid separation device and method for processing waste, comprising a separation shell, a support plate fixedly connected to the lower surface of the separation shell, a support frame fixedly connected to the bottom of the separation shell, a feeding separation device provided on the surface of the separation shell, a cleaning and discharge device provided inside the separation shell, and a compression separation device provided inside the separation shell. The feeding and separating device includes a water outlet pipe, the end of which is fixedly connected to the inner wall of the separating shell, and a valve is provided on the surface of the water outlet pipe. A sludge pump is fixedly connected to the inner wall of the support plate, and a hose is fixedly connected to the output end of the sludge pump. A feeding pipe is fixedly connected to the output end of the sludge pump. An inclined bucket is fixedly connected to the inner wall of the separating shell, and a separating cylinder is rotatably connected to the inner wall of the inclined bucket. A motor is fixedly connected to the inner wall of the support frame, and a rotating rod is fixedly connected to the output end of the motor. A rotating frame is fixedly connected to the end of the rotating rod. Filter holes are provided on the surface of the separating cylinder.

[0006] Furthermore, the water outlet pipe penetrates the separation shell and extends into the interior of the separation shell, the sludge pump is located above the support plate, and the feed pipe penetrates the separation shell and extends into the interior of the separation shell.

[0007] Furthermore, the rotating frame is located below the inclined bucket, the inner wall of the rotating frame is fixedly connected to the bottom of the separation cylinder, the number of filter holes is several, and the separation cylinder is located close to the inclined bucket and the rotating frame.

[0008] Furthermore, the cleaning and discharge device includes a support rod, the end of which is fixedly connected to the inner wall of the separation shell, a scraper fixedly connected to the end of the support rod away from the separation shell, a push plate fixedly connected to the surface of the rotating rod, a gear fixedly connected to the surface of the rotating rod, an internal gear meshing with the surface of the gear, a rotating bracket fixedly connected to the surface of the internal gear, a slot being opened in the inner wall of the rotating bracket, and a cleaning brush fixedly connected to the top of the rotating bracket.

[0009] Furthermore, the surface of the scraper is in contact with the inner wall surface of the separation cylinder, the surface of the cleaning brush is adapted to the surface of the separation cylinder, and the surface of the cleaning brush is in contact with the inner wall surface of the separation shell.

[0010] Furthermore, the bottom of the push plate contacts the bottom of the inner wall of the separation housing, the end of the internal gear is rotatably connected to the inner wall of the slot, the gear is located above the push plate, and the internal gear is located close to the gear and the rotating bracket.

[0011] Furthermore, the extrusion separation device includes a rotating gear, the inner wall of which is fixedly connected to the surface of a rotating rod, a rack meshing with the surface of the rotating gear, a force-applying rod fixedly connected to the end of the rack, an extrusion inclined plate hinged to the surface of the force-applying rod, a hinged pressure plate hinged to the end of the extrusion inclined plate away from the force-applying rod, a long thin rod fixedly connected to the bottom of the hinged pressure plate, an extrusion filter plate fixedly connected to the end of the long thin rod, a lifting groove provided on the inner wall of the scraper, a lifting support block slidably connected to the inner wall of the lifting groove, an inclined plate hinged to the surface of the extrusion filter plate, a shovel plate hinged to the end of the inclined plate away from the extrusion filter plate, a telescopic round rod fixedly connected to the surface of the shovel plate, and a fixed telescopic rod fixedly connected to the inner wall of the lifting groove.

[0012] Furthermore, the end of the lifting support block away from the lifting groove is fixedly connected to the top of the extrusion filter plate, the bottom of the shovel plate is in contact with the bottom of the inner wall of the separation shell, the end of the telescopic rod away from the shovel plate is fixedly connected to the surface of the scraper, and the end of the fixed telescopic rod away from the lifting groove is fixedly connected to the bottom of the lifting support block.

[0013] Furthermore, a separation method for a solid-liquid separation device for processing waste includes the following steps: S1: When the motor is turned on, the output end will drive the rotating rod to rotate. When the rotating rod rotates, it will drive the rotating frame to rotate, thereby driving the separation cylinder to rotate inside the inclined bucket. This allows the waste entering the separation cylinder to initially achieve solid-liquid separation through rotation. S2: When the rotating rod rotates, it will drive the push plate to rotate. The push plate will accelerate the discharge of the separated liquid and prevent it from accumulating inside the machine and affecting the separation work. At the same time, when the rotating rod rotates, it will drive the gear to rotate, thereby driving the internal gear to rotate in the opposite direction. S3: When the internal gear rotates, it will drive the cleaning brush to rotate along with the rotating bracket, so that the cleaning brush can clean the inner wall surface of the separator shell. When the separator cylinder rotates, the scraper will scrape and clean the inner wall of the separator cylinder to avoid the filter holes from being blocked and affecting the normal operation of the machine. S4: The rotating gear will drive the rack to move through meshing. When the rack moves, it will squeeze the squeezing inclined plate through the squeezing force rod, causing the hinged pressure plate to move up and down. In turn, the squeezing long thin rod will drive the squeezing filter plate to move up and down. At this time, the squeezing filter plate will drive the lifting support block to move up and down inside the lifting groove.

[0014] The present invention has the following beneficial effects: When the sludge pump of this invention is turned on, the output end will draw the waste to be processed through a hose, and then discharge it into the interior of the separation shell through the feeding pipe for solid-liquid separation. When the motor is turned on, the output end will drive the rotating rod to rotate. When the rotating rod rotates, it will drive the rotating frame to rotate, thereby driving the separation cylinder to rotate inside the inclined bucket. The waste entering the separation cylinder will initially achieve solid-liquid separation through rotation, improving the separation efficiency of the machine. At the same time, the separated liquid will be discharged into the bottom of the separation shell through the filter hole. At this time, the valve will be opened to discharge the liquid through the outlet pipe.

[0015] When the rotating rod of this invention rotates, it drives the push plate to rotate as well. The push plate accelerates the discharge of the separated liquid, preventing it from accumulating inside the machine and affecting the separation process. At the same time, the rotation of the rotating rod drives the gear to rotate, which in turn drives the internal gear to rotate. When the internal gear rotates, it drives the cleaning brush to rotate along with the rotating bracket. This allows the cleaning brush to clean the inner wall surface of the separation shell, preventing small amounts of debris from accumulating inside the machine and causing blockages that could affect the separation process. Meanwhile, the scraper scrapes and cleans the inner wall of the separation cylinder as it rotates, preventing the filter holes from becoming clogged and affecting the normal operation of the machine. The groove makes the position of the internal gear and the rotating bracket more stable when they rotate.

[0016] When the rotating rod of this invention rotates, it drives the rotating gear to rotate. At this time, the rotating gear drives the rack to move through meshing. When the rack moves, it squeezes the squeezing inclined plate through the squeezing force rod, causing the hinged pressure plate to move up and down. In turn, the squeezing long thin rod drives the squeezing filter plate to move up and down. At this time, the squeezing filter plate drives the lifting support block to move up and down inside the lifting groove. The squeezing filter plate squeezes the waste inside the separation cylinder, improving the machine's solid-liquid separation of waste. At the same time, the lifting support block stabilizes the movement of the squeezing filter plate, preventing deviation from affecting the machine's operation. When the squeezing filter plate moves up and down, it pushes the shovel plate to move back and forth through the squeezing inclined plate, causing the shovel plate to gather the solid waste at the bottom of the separation cylinder, thus facilitating the squeezing filter plate to squeeze the waste. This allows the machine to fully perform solid-liquid separation of waste. The telescopic round rod and the fixed telescopic rod make the position of the shovel plate and the lifting support block more stable when they move.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 - Figure 11 As shown, the present invention is a solid-liquid separation device and separation method for processing waste, including a separation shell 1, a support plate 2 fixedly connected to the lower surface of the separation shell 1, a support frame 3 fixedly connected to the bottom of the separation shell 1, a feeding separation device 4 provided on the surface of the separation shell 1, a cleaning and discharge device 5 provided inside the separation shell 1, and a squeezing separation device 6 provided inside the separation shell 1.

A valve 21 is installed on the surface of the water outlet pipe 20. A sludge pump 22 is fixedly connected to the inner wall of the support plate 2. When the sludge pump 22 is turned on, its output end draws the waste to be processed through a hose 23, thereby discharging it into the interior of the separating shell 1 through a feeding pipe 24 for solid-liquid separation. The output end of the sludge pump 22 is fixedly connected to both the hose 23 and the feeding pipe 24. An inclined bucket 25 is fixedly connected to the inner wall of the outer shell 1. A separation cylinder 26 is rotatably connected to the inner wall of the inclined bucket 25. A motor 27 is fixedly connected to the inner wall of the support frame 3. When the motor 27 is turned on, its output end will drive the rotating rod 28 to rotate. The output end of the motor 27 is fixedly connected to the rotating rod 28. When the rotating rod 28 rotates, it will drive the rotating frame 29 to rotate, thereby driving the separation cylinder 26 to rotate inside the inclined bucket 25. The end of the rotating rod 28 is fixedly connected to the rotating frame 29. Filter holes 30 are opened on the surface of the separation cylinder 26.

[0023] The water outlet pipe 20 penetrates the separation shell 1 and extends into the interior of the separation shell 1. The sludge pump 22 is located above the support plate 2. The feed pipe 24 penetrates the separation shell 1 and extends into the interior of the separation shell 1.

[0024] The rotating frame 29 is located below the inclined bucket 25. The inner wall of the rotating frame 29 is fixedly connected to the bottom of the separation cylinder 26. There are several filter holes 30. The separation cylinder 26 is located close to the inclined bucket 25 and the rotating frame 29.

[0025] The cleaning and discharge device 5 includes a support rod 40, the end of which is fixedly connected to the inner wall of the separation housing 1. A scraper 41 is fixedly connected to the end of the support rod 40 away from the separation housing 1. A pusher 42 is fixedly connected to the surface of the rotating rod 28. The pusher 42 will accelerate the discharge of the separated liquid and prevent it from accumulating inside the machine and affecting the separation work. A gear 44 is fixedly connected to the surface of the rotating rod 28. When the gear 44 rotates, it will drive the internal gear 45 to rotate in the opposite direction. The internal gear 45 is meshed with the surface of the gear 44. When the internal gear 45 rotates, it will drive the cleaning brush 43 to rotate together through the rotating bracket 46. Thus, the cleaning brush 43 cleans the surface of the separation cylinder 26 and the inner wall surface of the separation housing 1. The rotating bracket 46 is fixedly connected to the surface of the internal gear 45. A slot 47 is opened on the inner wall of the rotating bracket 29. The slot 47 makes the position of the internal gear 45 more stable when the rotating bracket 46 rotates. The cleaning brush 43 is fixedly connected to the top of the rotating bracket 46.

[0026] The surface of the scraper 41 is in contact with the inner wall surface of the separation cylinder 26, the surface of the cleaning brush 43 is adapted to the surface of the separation cylinder 26, and the surface of the cleaning brush 43 is in contact with the inner wall surface of the separation housing 1.

[0027] The bottom of the push plate 42 contacts the bottom of the inner wall of the separation housing 1, the end of the internal gear 45 is rotatably connected to the inner wall of the slot 47, the gear 44 is located above the push plate 42, and the internal gear 45 is located at a position close to each other between the gear 44 and the rotating bracket 46.

[0028] The extrusion separation device 6 includes a rotating gear 50, which drives a rack 51 to move through meshing. The inner wall of the rotating gear 50 is fixedly connected to the surface of the rotating rod 28. The rack 51 is meshed with the surface of the rotating gear 50. When the rack 51 moves, it extrudes the extrusion inclined plate 60 through the extrusion force rod 52, causing the hinged pressure plate 61 to move up and down. This, in turn, drives the extrusion filter plate 53 to move up and down through the extrusion elongated thin rod 62. The end of the rack 51 is fixedly connected to the force rod 52, and the surface of the force rod 52 is hingedly connected to the extrusion inclined plate 60. The end of the extrusion inclined plate 60 away from the force rod 52 is hingedly connected to the hinged pressure plate 61. The bottom of the hinged pressure plate 61 is fixedly connected to the elongated thin rod 62, and the end of the elongated thin rod 62 is fixedly connected to the extrusion filter plate 53. The extrusion filter plate 53 then drives the lifting support block 55 to rise. The internal movement of the lowering groove 54 causes the squeezing filter plate 53 to squeeze the waste inside the separation cylinder 26. The inner wall of the scraper 41 is provided with a lifting groove 54, and a lifting support block 55 is slidably connected to the inner wall of the lifting groove 54. The lifting support block 55 makes the movement of the squeezing filter plate 53 stable and avoids deviation that affects the operation of the machine. The surface of the squeezing filter plate 53 is hinged to an inclined plate 56, which pushes the shovel plate 57 to move back and forth, so that the shovel plate 57 gathers the solid waste at the bottom of the separation cylinder 26. The end of the inclined plate 56 away from the squeezing filter plate 53 is hinged to the shovel plate 57. The surface of the shovel plate 57 is fixedly connected to a telescopic round rod 58. The telescopic round rod 58 and the fixed telescopic rod 59 make the position of the shovel plate 57 and the lifting support block 55 more stable when they move. The inner wall of the lifting groove 54 is fixedly connected to a fixed telescopic rod 59.

[0029] The end of the lifting support block 55 away from the lifting groove 54 is fixedly connected to the top of the extrusion filter plate 53, the bottom of the shovel plate 57 is in contact with the bottom of the inner wall of the separation shell 1, the end of the telescopic rod 58 away from the shovel plate 57 is fixedly connected to the surface of the scraper 41, and the end of the fixed telescopic rod 59 away from the lifting groove 54 is fixedly connected to the bottom of the lifting support block 55.

[0030] Furthermore, a separation method for a solid-liquid separation device for processing waste includes the following steps: S1: When the motor 27 is turned on, the output end will drive the rotating rod 28 to rotate. When the rotating rod 28 rotates, it will drive the rotating frame 29 to rotate, thereby driving the separation cylinder 26 to rotate inside the inclined bucket 25, so that the waste entering the separation cylinder 26 can initially achieve solid-liquid separation through rotation. S2: When the rotating rod 28 rotates, it will drive the push plate 42 to rotate. The push plate 42 will accelerate the discharge of the separated liquid and avoid accumulation inside the machine, which will affect the separation work. At the same time, when the rotating rod 28 rotates, it will drive the gear 44 to rotate, which will drive the internal gear 45 to rotate in the opposite direction. S3: When the internal gear 45 rotates, it will drive the cleaning brush 43 to rotate together through the rotating bracket 46, so that the cleaning brush 43 will clean the inner wall surface of the separation shell 1. When the separation cylinder 26 rotates, the scraper 41 will scrape and clean the inner wall of the separation cylinder 26 to avoid the filter hole 30 from being blocked and affecting the normal operation of the machine. S4: The rotating gear 50 will drive the rack 51 to move through meshing. When the rack 51 moves, it will squeeze the squeezing inclined plate 60 through the squeezing force rod 52, causing the hinged pressure plate 61 to move up and down. In turn, the squeezing filter plate 53 will move up and down through the squeezing long thin rod 62. At this time, the squeezing filter plate 53 will drive the lifting support block 55 to move up and down inside the lifting groove 54.

[0031] When in use, the sludge pump 22 is turned on, and the output end draws the waste to be processed through the hose 23, which is then discharged into the interior of the separation shell 1 through the feed pipe 24 for solid-liquid separation. When the motor 27 is turned on, the output end drives the rotating rod 28 to rotate. When the rotating rod 28 rotates, it drives the rotating frame 29 to rotate, which in turn drives the separation cylinder 26 to rotate inside the inclined bucket 25. This rotation allows the waste entering the separation cylinder 26 to initially achieve solid-liquid separation, improving the machine's separation efficiency. At the same time, the separated liquid is discharged into the bottom of the separation shell 1 through the filter hole 30. At this time, the valve 21 is opened to allow the liquid to flow out. The liquid is discharged through the outlet pipe 20. When the rotating rod 28 rotates, it drives the push plate 42 to rotate, which accelerates the discharge of the separated liquid and prevents it from accumulating inside the machine and affecting the separation process. At the same time, when the rotating rod 28 rotates, it drives the gear 44 to rotate, which in turn drives the internal gear 45 to rotate. When the internal gear 45 rotates, it drives the cleaning brush 43 to rotate through the rotating bracket 46, so that the cleaning brush 43 cleans the inner wall surface of the separation shell 1, preventing small amounts of debris from accumulating inside the machine and causing blockages that affect the separation process. Meanwhile, the scraper 41 scrapes the inner wall of the separation cylinder 26 as it rotates. The wall is scraped and cleaned to prevent the filter holes 30 from becoming clogged and affecting the normal operation of the machine. The slot 47 makes the position of the internal gear 45 and the rotating bracket 46 more stable when they rotate. When the rotating rod 28 rotates, it will drive the rotating gear 50 to rotate. At this time, the rotating gear 50 will drive the rack 51 to move through meshing. When the rack 51 moves, it will squeeze the squeezing inclined plate 60 through the squeezing force rod 52, causing the hinged pressure plate 61 to move up and down. In turn, it will drive the squeezing filter plate 53 to move up and down through the squeezing long thin rod 62. At this time, the squeezing filter plate 53 will drive the lifting support block 55 to move up and down inside the lifting groove 54. The squeezing filter plate 53 will... The waste inside the separation cylinder 26 is squeezed to improve the machine's ability to separate solids and liquids. At the same time, the lifting support block 55 stabilizes the movement of the squeezing filter plate 53, preventing it from shifting and affecting the machine's operation. When the squeezing filter plate 53 moves up and down, it pushes the shovel plate 57 to move back and forth through the squeezing inclined plate 56, causing the shovel plate 57 to gather the solid waste at the bottom of the separation cylinder 26. This facilitates the squeezing of the waste by the squeezing filter plate 53, allowing the machine to fully separate solids and liquids. The telescopic round rod 58 and the fixed telescopic rod 59 make the position of the shovel plate 57 and the lifting support block 55 more stable when they move.

When the rotating rod (28) rotates, it will drive the rotating frame (29) to rotate, thereby driving the separation cylinder (26) to rotate inside the inclined bucket (25), so that the waste entering the separation cylinder (26) can initially achieve solid-liquid separation through rotation. S2: When the rotating rod (28) rotates, it will drive the push plate (42) to rotate. The push plate (42) will make the separated liquid discharge faster and avoid accumulation inside the machine, which will affect the separation work. At the same time, when the rotating rod (28) rotates, it will drive the gear (44) to rotate, thereby driving the internal gear (45) to rotate in the opposite direction. S3: When the internal gear (45) rotates, it will drive the cleaning brush (43) to rotate together through the rotating bracket (46), so that the cleaning brush (43) will clean the inner wall surface of the separation shell (1). When the separation cylinder (26) rotates, the scraper (41) will scrape and clean the inner wall of the separation cylinder (26) to avoid the filter hole (30) from being blocked and affecting the normal operation of the machine. S4: The rotating gear (50) will drive the rack (51) to move through meshing. When the rack (51) moves, it will squeeze the squeezing inclined plate (60) through the squeezing force rod (52), causing the hinged pressure plate (61) to move up and down. This will drive the squeezing filter plate (53) to move up and down through the squeezing long thin rod (62). At this time, the squeezing filter plate (53) will drive the lifting support block (55) to move up and down inside the lifting groove (54).
