Description

Technical Field

[0001] This invention relates to the field of waste sorting and treatment, and more specifically, to a household waste sorting device. Background Technology

[0002] Household waste can generally be divided into four categories: recyclable waste, kitchen waste, hazardous waste, and other waste. This division is to align with the basic operation of waste disposal facilities. Many existing residential communities and parks have corresponding waste sorting and recycling stations to help community members sort their household waste. These stations can effectively improve the urban and rural environment and promote resource recycling. Many existing waste sorting and recycling stations typically have a row of trash cans, with different cans corresponding to the four main categories of household waste. Users simply place their waste into the appropriate bins to sort their household waste. However, most household waste, especially kitchen waste, contains wastewater and smelly food. When these are put into the trash cans, the wastewater can easily spill out, which not only breeds bacteria but also emits odors, placing a huge burden on the waste collection staff.

[0003] Chinese patent application publication number CN115027838A discloses a household waste sorting and processing device. Through the support plates on both sides of the inner wall of the device box and the filter screen on its outer surface, the wastewater contained in the waste in the disposal chamber can be filtered and stored at the bottom of the device box. A corresponding sewage pipe is set on the right wall of the bottom of the device box, which can discharge the wastewater stored at the bottom of the device box through the sewage pipe, effectively preventing wastewater from spilling out when workers collect the waste.

[0004] Existing patents offer solutions to the above problems, but their method of filtering sewage through a filter before discharge is not effective in removing the sewage contained in the garbage. The sewage adsorbed inside the garbage cannot be effectively discharged and will still spill out during subsequent transfer and processing. In addition, the sewage remaining at the bottom will still emit an odor without purification treatment, which will still place a huge burden on the garbage recycling workers.

[0005] Therefore, a household waste sorting device is proposed. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a household waste sorting device to solve the problems that the sewage adsorbed inside the waste cannot be effectively discharged and the sewage remaining at the bottom cannot be purified.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A household waste sorting device includes a waste bin body, and a corresponding delivery frame is fixedly installed on the upper part of the waste bin body; The inside of the trash can is equipped with a servo extrusion mechanism, the middle of the trash can is equipped with a servo discharge mechanism, and a U-shaped lifting frame is fixedly installed at the bottom of the trash can. A wastewater reprocessing mechanism is inserted and installed inside the U-shaped lifting frame. The servo extrusion mechanism includes an upper extrusion mechanism and a lower extrusion frame located at the output end, which are positioned close to each other to further extrude household waste and fully discharge the wastewater contained within it. The wastewater reprocessing mechanism includes an outwardly folding partition that can be flipped open and a physical adsorption mechanism installed at its bottom, which is used to further filter debris and impurities in the wastewater and to separate the wastewater that can emit odors. At the same time, the porous medium in the physical adsorption mechanism is used to adsorb odor molecules.

[0009] Furthermore, the servo extrusion mechanism includes a horizontal plate frame fixedly installed at the front and rear ends of the middle of the inside of the trash can body. A reinforcing frame that fits against the inner wall of the trash can body is fixedly installed on the left side of the horizontal plate frame. Limiting rods are fixedly installed at the upper and lower ends of the left side of the horizontal plate frame. Threaded rods are movably installed at the upper and lower ends of the right side of the horizontal plate frame. The limiting rods and threaded rods at the upper and lower ends of the horizontal plate frame are integral structures. The threaded rods at the upper and lower ends of the horizontal plate frame have the same opening interval but opposite thread directions. An upper extrusion mechanism and a lower extrusion frame are slidably installed at the same position at the upper and lower ends of the horizontal plate frame through the limiting rods. The structure of the lower extrusion frame is the same as that of the upper extrusion mechanism. A synchronous drive mechanism corresponding to the bottom of the threaded rod is installed on the right side of the bottom of the trash can body.

[0010] Furthermore, the synchronous drive mechanism includes a first gear sleeve fixedly installed at the bottom of the threaded rod, a gear track sleeve meshing with the outer side of the first gear sleeve, and anti-detachment clamping discs corresponding to the limiting position of the gear track sleeve fixedly installed at the bottom of the first gear sleeve. The synchronous drive mechanism also includes an L-shaped side plate fixedly installed at the middle position of the right side of the bottom of the garbage can body, a first servo motor fixedly installed on the left side of the L-shaped side plate, a second gear sleeve fixedly installed at the output end of the upper surface of the first servo motor, the second gear sleeve meshing with the inner wall of the gear track sleeve, and baffles fixedly installed on both sides of the upper surface of the first servo motor.

[0011] The baffle is used to clamp the gear track sleeve in the middle, so that the gear track sleeve is closely fitted with the second gear sleeve head.

[0012] Furthermore, the upper extrusion mechanism includes a U-shaped frame slidably mounted on the outside of the limiting support rod. Both ends of the right side of the U-shaped frame are provided with threaded openings that mesh with the threaded rod. Both sides of the inner wall of the U-shaped frame are provided with first guide rail slots. The rear left side of the U-shaped frame is provided with a reserved sleeve corresponding to and communicating with the first guide rail slot. A second servo motor is fixedly mounted on the upper side of the reserved sleeve. A third gear sleeve is fixedly mounted on the bottom output end of the second servo motor. A side frame is slidably inserted into the interior of the first guide rail slot. A corresponding filter sleeve is provided on the inner wall of the side frame. A corresponding first locking block is fixedly mounted on the front side of the side frame. A toothed plate is fixedly mounted on the rear side of the side frame, meshing with the third gear sleeve. Second external openings are provided at the upper and lower ends of the left side of the garbage bin, corresponding to the endpoints of the threaded rod. Temporary collection cavity boxes are fixedly mounted on the outer surfaces of the second external openings. The inner cavity dimensions of the temporary collection cavity boxes are the same as those of the side frame.

[0013] The third gear sleeve is always engaged with the toothed plate. When the side frame is conveyed into the interior of the temporary receiving cavity box, the outer side of the toothed plate is still engaged with the third gear sleeve, that is, the side frame does not completely enter the interior of the temporary receiving cavity box.

[0014] Furthermore, an inner frame is fixedly installed on the inner wall of the side frame, and screws are fixedly installed at the four corners of the upper surface of the inner frame. The filter sleeve is fitted onto the upper surface of the inner frame through the screws. A reserved round opening corresponding to the screw is provided at the four corners of the filter sleeve, and a nut sleeve is rotatably installed on the upper side of the screw.

[0015] Furthermore, the servo discharging mechanism includes an extension frame fixedly installed at the middle position of the right side of the trash can body. A telescopic motor is fixedly installed on the inner wall of the extension frame. The output end of the telescopic motor passes through the trash can body and extends into it, and a mouth-shaped frame is fixedly installed thereon. A telescopic sealing cloth cover is fixedly installed on the upper and lower sides of the mouth-shaped frame. A fitting frame is fixedly installed on the outer side of the telescopic sealing cloth cover. The fitting frame is made of magnetic material. The telescopic sealing cloth covers at the upper and lower ends of the mouth-shaped frame are respectively adsorbed onto the inner wall of the upper extrusion mechanism and the lower extrusion frame through the fitting frame. A first external opening corresponding to the mouth-shaped frame is provided at the middle position of the left side of the trash can body. A second locking block is fixedly installed at the front and rear positions of the right side of the mouth-shaped frame. The servo discharging mechanism also includes a second guide rail groove provided on the inner wall of the horizontal plate frame. The second locking block is slidably installed inside the second guide rail groove. Collection bag hanging plates for setting collection bags are fixedly installed at both ends of the outer side of the first external opening.

[0016] Furthermore, the wastewater retreatment mechanism includes a receiving box inserted and installed inside the U-shaped lifting frame. An outward-folding partition is movably installed on the left side of the inner wall of the receiving box. Multiple inclined baffles are arranged and fixedly installed on the upper surface of the outward-folding partition. Multiple holes are arranged on the surface of each inclined baffle. Partitions are fixedly installed at both ends of the right inner wall of the receiving box. The outward-folding partition rests against the upper surface of the partition and is inclined downward.

[0017] Furthermore, the physical adsorption mechanism includes an inclined pad fixedly installed at the bottom of the outward-folding partition. A slot is fixedly installed at the bottom of the inclined pad, and an insert plate is inserted into the slot. A third servo motor is fixedly installed at the bottom of the insert plate, and a three-way sleeve is fixedly installed at the output end of the third servo motor.

[0018] Furthermore, U-shaped sockets are fixedly installed on the bottom of each of the three sides of the three-way sleeve frame, and corresponding perforated cavity inserts are inserted into the interior of each U-shaped socket. A reset spring sleeve is fixedly installed on the upper part of each perforated cavity insert. Positioning sleeves corresponding to the reset spring sleeves are provided on the upper part of each of the three sides of the three-way sleeve frame. Handles for easy handling are provided on the outer side of each perforated cavity insert.

[0019] Furthermore, the left side of the receiving box is transparent, and the outer surface of the right side of the receiving box and the inner wall of the U-shaped lifting frame are both provided with corresponding magnetic coatings. Handles are fixedly installed at both ends of the right side of the receiving box.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The servo squeezing mechanism inside the garbage bin can servo squeeze the domestic waste inside. The lower squeezing frame and the upper squeezing mechanism, which move synchronously at the upper and lower ends, can fully and thoroughly squeeze out the sewage inside under the filtering effect of the filter sleeve plate. The sewage is collected and treated centrally by the wastewater reprocessing mechanism set at the bottom of the U-shaped lifting frame. This effectively solves the problem that the sewage adsorbed inside the garbage cannot be effectively discharged and the sewage left at the bottom cannot be purified in the existing technology.

[0021] (2) By cooperating with the servo discharge mechanism installed on the outside of the garbage can, the household waste that has been squeezed by the lower squeezing frame and the upper squeezing mechanism can be pushed out from the first external opening along the motor extension direction of the motor extension motor, so that the garbage can be removed in time, effectively preventing it from rotting, deteriorating and turning into water and smelling bad inside the garbage can, further reducing the workload, eliminating the need for manual transfer and collection, saving the workload of garbage sorting staff, and effectively avoiding the possibility of cross-infection from contact with bacteria during the work process.

[0022] (3) By setting up a temporary collection cavity box with a corresponding lower squeezing frame and upper squeezing mechanism on the outside of the garbage can, the filter sleeve used for squeezing and dehydration can be moved to the outside during normal use without affecting the normal garbage disposal. Furthermore, the filter sleeve can be directly disassembled from the inside of the inner frame by loosening the nut sleeve, which further reduces the daily workload of garbage sorting staff and is more practical.

[0023] (4) The wastewater re-treatment mechanism installed at the bottom of the U-shaped lifting frame can stably guide the wastewater to the bottom of the receiving box through the inclined outward-folding partition. While collecting the odorous water in real time, the outward-folding partition can also be used to separate the garbage can from top to bottom, effectively isolating the odor at the bottom. At the same time, the outward-folding partition can be used to quickly disinfect and clean the bottom of the garbage can, further reducing the daily workload of garbage sorting staff.

[0024] (5) The inclined baffles installed on the surface by the outward-folding baffle can also filter the debris and impurities squeezed out of the sewage while the outward-folding baffles divert sewage, so as to prevent the garbage such as irregular metal from being carried away by the wastewater. There is no need for manual treatment of the garbage in the sewage, which further improves the separation efficiency of wastewater and solid garbage and further reduces the daily workload of garbage sorting staff.

[0025] (6) Through the physical adsorption mechanism installed at the bottom of the outward-folding partition, the corresponding porous medium can be placed inside the perforated cavity box to adsorb the odor molecules in the wastewater at the bottom. This effectively solves the problem that the sewage retained at the bottom in the existing technology cannot be purified. At the same time, the stirring effect of the third servo motor can further improve the efficiency of sewage purification and improve the working environment of the garbage sorting work area. In addition, the porous medium adsorption end can be quickly disassembled and assembled using the reset spring sleeve, which further reduces the daily workload of garbage sorting workers.

[0029] Please see Figures 1 to 8 A household waste sorting device includes a waste bin 1, and a corresponding delivery frame 2 is fixedly installed on the upper part of the waste bin 1; The inside of the trash can body 1 is equipped with a servo extrusion mechanism 3, the middle position of the trash can body 1 is equipped with a servo discharge mechanism 4, the bottom of the trash can body 1 is fixedly equipped with a U-shaped lifting frame 5, and a wastewater reprocessing mechanism 6 is inserted and installed inside the U-shaped lifting frame 5. The servo extrusion mechanism 3 includes an upper extrusion mechanism 37 and a lower extrusion frame 36 located at the output end, which are positioned close to each other to further extrude household waste and fully discharge the wastewater contained within it. The wastewater reprocessing mechanism 6 includes an outwardly folding partition 62 that can be flipped open and a physical adsorption mechanism 7 installed at its bottom, which is used to further filter debris and impurities in the wastewater and to separate the wastewater that can emit odors.

[0030] like Figure 1 , Figure 3 As shown, the servo extrusion mechanism 3 includes a horizontal plate frame 31 fixedly installed at the front and rear ends of the middle of the inside of the trash can body 1. A reinforcing frame 32 that fits against the inner wall of the trash can body 1 is fixedly installed on the left side of the horizontal plate frame 31. Limiting support rods 33 are fixedly installed at the upper and lower ends of the left side of the horizontal plate frame 31. Threaded rods 34 are movably installed at the upper and lower ends of the right side of the horizontal plate frame 31. The limiting support rods 33 and threaded rods 34 at the upper and lower ends of the horizontal plate frame 31 are integral structures. The threaded rods 34 at the upper and lower ends of the horizontal plate frame 31 have the same opening spacing but opposite thread directions. An upper extrusion mechanism 37 and a lower extrusion frame 36 are slidably installed at the same position at the upper and lower ends of the horizontal plate frame 31 through the limiting support rods 33. The structure of the lower extrusion frame 36 is the same as that of the upper extrusion mechanism 37. A synchronous drive mechanism 35 corresponding to the bottom of the threaded rod 34 is installed on the right side of the bottom of the trash can body 1.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the synchronous drive mechanism 35 includes a first gear sleeve 351 fixedly installed at the bottom of the threaded rod 34. A gear track sleeve 353 is meshed on the outer side of the first gear sleeve 351. Anti-detachment chucks 352 corresponding to the limiting position of the gear track sleeve 353 are fixedly installed at the bottom of the first gear sleeve 351. The synchronous drive mechanism 35 also includes an L-shaped side plate 354 fixedly installed at the middle position of the right side of the bottom of the garbage can body 1. A first servo motor 355 is fixedly installed on the left side of the L-shaped side plate 354. A second gear sleeve 357 is fixedly installed at the output end of the upper surface of the first servo motor 355. The second gear sleeve 357 meshes with the inner wall of the gear track sleeve 353. Baffles 356 are fixedly installed on both sides of the upper surface of the first servo motor 355.

[0032] The baffle 356 is used to clamp the gear track sleeve 353 in the middle, so that the gear track sleeve 353 is closely fitted with the second gear sleeve head 357.

[0033] like Figure 3 , Figure 5 As shown, the upper extrusion mechanism 37 includes a U-shaped frame 371 slidably mounted on the outside of the limiting support rod 33. Both ends of the right side of the U-shaped frame 371 are provided with threaded openings that mesh with the threaded rod 34. The inner walls of the U-shaped frame 371 are provided with first guide rail slots 375 on both sides. The rear left side of the U-shaped frame 371 is provided with a reserved sleeve 372 corresponding to and communicating with the first guide rail slots 375. A second servo motor 373 is fixedly mounted on the upper side of the reserved sleeve 372. A third gear sleeve 374 is fixedly mounted on the bottom output end of the second servo motor 373. The first guide rail slot 375... An internal sliding insert is installed with a side frame 376. The inner wall of the side frame 376 is provided with a corresponding filter sleeve 3711. A corresponding first locking block 377 is fixedly installed on the front side of the side frame 376. A toothed plate 378 is fixedly installed on the rear side of the side frame 376. The toothed plate 378 meshes with the third gear sleeve 374. A second external opening 10 is provided at the upper and lower ends of the left side of the trash can body 1 at the end positions of the threaded rod 34. A temporary collection cavity box 12 is fixedly installed on the outer surface of the second external opening 10. The inner cavity size of the temporary collection cavity box 12 is the same as that of the side frame 376.

[0034] The third gear sleeve 374 is always engaged with the toothed plate 378. When the side frame 376 is transported into the interior of the temporary receiving cavity box 12, the outer side of the toothed plate 378 is still engaged with the third gear sleeve 374, that is, the side frame 376 does not completely enter the interior of the temporary receiving cavity box 12.

[0035] like Figure 5 As shown, an inner frame 379 is fixedly installed on the inner wall of the side frame 376. Screws 3710 are fixedly installed at the four corners of the upper surface of the inner frame 379. The filter sleeve 3711 is sleeved on the upper surface of the inner frame 379 through the screws 3710. The four corners of the filter sleeve 3711 are provided with reserved round openings 3712 corresponding to the screws 3710. Nut sleeves 3713 are rotatably installed on the upper side of the screws 3710.

[0036] like Figure 1 , Figure 2 , Figure 6As shown, the servo discharging mechanism 4 includes an extension frame 41 fixedly installed at the middle position on the right side of the trash can body 1. A telescopic motor 42 is fixedly installed on the inner wall of the extension frame 41. The output end of the telescopic motor 42 passes through the trash can body 1 and extends into it, and a mouth-shaped frame 43 is fixedly installed thereon. A retractable sealing cloth cover 46 is fixedly installed on both the upper and lower sides of the mouth-shaped frame 43. A fitting frame 47 is fixedly installed on the outer side of the retractable sealing cloth cover 46. The fitting frame 47 is made of magnetic material. The retractable sealing cloth cover 46 at the upper and lower ends of the mouth-shaped frame 43 is connected to the retractable sealing cloth cover 46. The fitted frame 47 is respectively adsorbed onto the inner wall of the upper squeezing mechanism 37 and the lower squeezing frame 36. A first external opening 9 corresponding to the orifice frame 43 is provided at the middle position on the left side of the trash can body 1. A second locking block 44 is fixedly installed at the front and rear positions on the right side of the orifice frame 43. The servo discharge mechanism 4 also includes a second guide rail groove 45 provided on the inner wall of the horizontal plate frame 31. The second locking block 44 is slidably installed inside the second guide rail groove 45. Collection bag hanging plates 11 for setting collection bags are fixedly installed at both ends of the outer side of the first external opening 9.

[0037] By adopting the above technical solution, the problem that sewage adsorbed inside the garbage cannot be effectively discharged in the existing technology is solved. First, the rotation of the second gear sleeve 357 at the output end of the first servo motor 355 in the synchronous drive mechanism 35 drives the gear track sleeve 353 on the inner wall of the baffle 356 to rotate synchronously. The synchronously rotating gear track sleeve 353 can drive the first gear sleeves 351 on both sides to rotate synchronously. The synchronously rotating first gear sleeves 351 can drive the threaded rod 34 to rotate synchronously, so that the upper extrusion mechanism 37 and the lower extrusion frame 36 at the upper and lower ends of the horizontal plate frame 31 can be synchronously extended outward along the limiting support rod 33, so that the upper extrusion mechanism 37 and the lower extrusion frame 36 move to the outermost position, thereby making them Aligning the second external openings 10 at the top and bottom of the trash can 1 respectively, and then through the rotation of the third gear sleeve 374 at the bottom output end of the second servo motor 373, the toothed plate 378 on the upper outer side of the trash can 1 moves along the first guide rail slot 375, causing the side frame 376 to enter the interior of the temporary collection cavity box 12 through the second external opening 10. This opens the upper delivery frame opening 2 of the trash can 1, while the lower squeezing frame 36 at the bottom does not enter the interior of the temporary collection cavity box 12. At this time, the corresponding trash cans can be put into the interior of the delivery frame opening 2. In actual use, a corresponding number of trash cans 1 can be set for classified collection and recycling. When the amount of trash collected inside the trash can 1 reaches a certain amount, the staff only needs to collect the trash. A corresponding collection bag can be set on the outside of the bag hanging plate 11. Through the reverse rotation of the third gear sleeve 374 at the bottom output end of the second servo motor 373, the side frame 376 can be returned to the inside of the U-shaped frame 371 along the first guide rail slot 375. When the side frame 376 is completely retracted into the U-shaped frame 371, the gear track sleeve 353 can be controlled to drive the threaded rod 34 to rotate in the reverse direction through the reverse drive of the first servo motor 355 in the synchronous drive mechanism 35. This causes the upper extrusion mechanism 37 and the lower extrusion frame 36 at the upper and lower ends to move closer to the middle along the limit support rod 33, and to be extruded by the filter sleeve 3711. During the extrusion process, the wastewater generated by the waste can be discharged along the surface of the filter sleeve 3711. The circular opening is squeezed outwards, while the upper squeezing mechanism 37 and lower squeezing frame 36, which are close together at the top and bottom, can no longer squeeze further. This causes the internal waste to be squeezed into a cube of the same size as the orifice frame 43. At this point, servo discharge mechanism 4 can be used again for servo discharge. Specifically, the extension of the output end of the motor extension motor 42 is increased to push the orifice frame 43 outwards from the first external opening 9. Since the retractable sealing cloth cover 46 set on the upper and lower sides of the orifice frame 43 is attached to the inner wall of the upper squeezing mechanism 37 and lower squeezing frame 36 through the fitting frame 47, it does not affect the follow-out process during the push-out. The pushed-out waste can fall into the collection bag on the outside of the collection bag hanging plate 11 for external dehydration and collection.The detached garbage-shaped frame 43, retracted by the output of the telescopic motor 42, can re-enter the garbage bin 1 through the first external opening 9. During this process, the outer fitting frame 47 of the telescopic sealing cover 46 can again adhere to the inner wall of the upper squeezing mechanism 37 and the lower squeezing frame 36. After the detached frame 43 retracts, the lower squeezing frame 36 and the upper squeezing mechanism 37 are moved to the outermost position again by the synchronous drive mechanism 35, simultaneously bringing the unfolded telescopic sealing cover 46 back on. The upper squeezing mechanism 37 is then retracted into the temporary collection cavity box 12 by the second servo motor 373, and can then be reused for garbage collection. This repeated process effectively reduces the workload of garbage sorting workers and avoids the possibility of cross-infection from bacterial contact during the work process. It also effectively solves the problem in existing technologies where wastewater adsorbed inside the garbage cannot be effectively discharged.

[0038] like Figure 1 , Figure 7 , Figure 8 As shown, the wastewater reprocessing mechanism 6 includes a receiving box 61 inserted and installed inside the U-shaped lifting frame 5. An outward-folding partition 62 is movably installed on the left side of the inner wall of the receiving box 61. Multiple inclined baffles 64 are arranged and fixedly installed on the upper surface of the outward-folding partition 62. Multiple holes 65 are arranged on the surface of each inclined baffle 64. Partitions 63 are fixedly installed at both ends of the right inner wall of the receiving box 61. The outward-folding partition 62 leans against the upper surface of the partition 63 and is in a downward-sloping state.

[0039] like Figure 8 As shown, the physical adsorption mechanism 7 includes an inclined pad 71 fixedly installed at the bottom of the outward-folding partition 62. A slot 72 is fixedly installed at the bottom of the inclined pad 71. An insert plate 73 is inserted into the slot 72. A third servo motor 74 is fixedly installed at the bottom of the insert plate 73. A three-way sleeve 75 is fixedly installed at the output end of the third servo motor 74.

[0040] like Figure 8 As shown, U-shaped sockets 76 are fixedly installed on the bottom of three sides of the three-way sleeve frame 75. Corresponding perforated cavity boxes 78 are inserted into the interior of each U-shaped socket 76. A reset spring sleeve head 79 is fixedly installed on the upper part of each perforated cavity box 78. Positioning sleeves 77 corresponding to the reset spring sleeve heads 79 are provided on the upper part of three sides of the three-way sleeve frame 75. Handles for easy handling are provided on the outer side of each perforated cavity box 78.

[0041] like Figure 7As shown, the left side of the receiving box 61 is transparent, and the outer surface of the right side of the receiving box 61 and the inner wall of the U-shaped lifting frame 5 are both provided with corresponding magnetic coatings. Both ends of the right side of the receiving box 61 are fixedly installed with handles 8.

[0042] By adopting the above technical solution, the problem that the sewage remaining at the bottom of the existing technology cannot be purified is solved. First, the sewage squeezed and removed by the lower squeezing frame 36 and the upper squeezing mechanism 37 falls into the inside of the receiving box 61. The sewage entering the receiving box 61 is first guided by the outward-folding partition 62 and enters the bottom of the receiving box 61 stably. At the same time, the multiple inclined baffles 64 set on the upper surface of the outward-folding partition 62 can filter out debris and impurities in the sewage, which can prevent irregular metal and other garbage from being carried away by the wastewater. There is no need for manual treatment of garbage in the sewage, which further improves the separation efficiency of wastewater and fixed garbage and further reduces the daily workload of garbage sorting workers. The sewage entering the bottom of the receiving box 61 can drive the perforated cavity boxes 78 on the three sides to move in the sewage under the action of the rotation of the three-way sleeve frame 75 at the output end of the third servo motor 74. The device is stirred and rotated, using an adsorption medium inside to adsorb odorous impurities in the wastewater. Under the isolation effect of the outward-folding partition 62, the wastewater is further purified by physical adsorption, improving the working environment of the waste sorting area. At the same time, the perforated cavity insert 78 can be quickly disassembled and assembled from the U-shaped insert 76 of the three-way frame 75 by the cooperation of the return spring sleeve 79 and the positioning sleeve 77, further reducing the daily workload of waste sorting staff. In addition, the receiving box 61 can be opened by simply rotating it upward around the outward-folding partition 62 to clean its interior and the physical adsorption mechanism 7. When cleaning the physical adsorption mechanism 7, it can be disassembled as a whole by the insertion relationship between the insert plate 73 and the slot 72, which is more convenient and efficient, and effectively solves the problem that the wastewater left at the bottom cannot be purified in the existing technology.

[0043] Working principle: First, the first servo motor 355 in the synchronous drive mechanism 35 moves the upper extrusion mechanism 37 and the lower extrusion frame 36 along the limiting support rod 33 to the outermost side of the threaded rod 34, so that the side frame 376 of the upper extrusion mechanism 37 is aligned with the second external opening 10. Then, under the rotation of the third gear sleeve 374 at the output end of the second servo motor 373, the side frame 376 is transferred to the inside of the temporary receiving cavity box 12, and the delivery box opening 2 is opened for garbage disposal. After a certain amount of garbage has been disposed of, the side frame 376 is returned to the inside of the U-shaped frame 371 by the reverse drive of the second servo motor 373. Then, the synchronous drive mechanism... Under the reverse drive of 35, the upper extrusion mechanism 37 and the lower extrusion frame 36 at the upper and lower ends move closer to the middle along the limiting support rod 33 to extrude and dehydrate the internal waste. After dehydration, the waste is pushed out through the first external opening 9 and collected into the collection bag outside the collection bag hanging plate 11 by the extension of the motor extension motor 42 of the servo discharge mechanism 4. The extruded sewage enters the interior of the receiving box 61 through the outward-turning partition 62. After being filtered by the inclined baffle 64, it is then adsorbed by the perforated cavity insert box 78 of the physical adsorption mechanism 7, and stirred and adsorbed to purify the sewage. Finally, it is cleaned by transferring the receiving box 61.
