Description

Technical Field

[0001] This application relates to the field of slag removal technology, and in particular to a spiral slag removal device that is easy to clean. Background Technology

[0002] Slag removal devices are used to remove impurities from liquids or semi-solids, and are commonly used in industrial production, food processing, sewage treatment, papermaking, and other fields.

[0003] Currently, wastewater generated in kitchens needs to be separated by an oil-water separator before it can be discharged. Before entering the oil-water separator, the wastewater needs to be treated with a sludge removal device. Referring to the authorized Chinese patent CN214936485U, the sludge removal device includes a housing, inside which a sludge removal filter is installed. A screw propeller is rotatably mounted between the sludge removal filter and the housing. Kitchen wastewater enters the sludge removal filter inside the housing through an inlet pipe. The rotation of the screw propeller moves the kitchen waste, causing the wastewater within the kitchen waste to drip off the sludge removal filter, thus completing the separation of kitchen waste and wastewater.

[0004] Because kitchen waste contains a lot of grease, when the screw propeller moves the kitchen waste, the grease in the kitchen waste easily adheres to the slag removal filter screen. After a large amount of grease adheres, the filter pores in the slag removal filter screen are easily blocked by kitchen waste, which leads to poor sewage separation effect in kitchen waste. Summary of the Invention

[0005] To improve the problem of poor wastewater separation in kitchen waste, this application provides a spiral slag removal device that is easy to clean.

[0006] The spiral slag removal device that is easy to clean provided in this application adopts the following technical solution:

[0007] A spiral slag removal device for easy cleaning includes a housing, a rotating shaft rotatably mounted inside the housing, spiral blades mounted on the rotating shaft, a slag removal filter cylinder covered by the spiral blades inside the housing, a feed pipe connected to one end of the slag removal filter cylinder on the housing, a discharge pipe connected to the other end of the slag removal filter cylinder on the housing, a discharge pipe at the bottom of the housing, spiral brushes mounted on the spiral blades abutting against the inner wall of the slag removal filter cylinder, and a first cleaning mechanism on the outer side of the slag removal filter cylinder. The first cleaning mechanism includes a first cleaning frame, a transmission assembly, and a first brush strip. The first cleaning frame is rotatably mounted on the slag removal filter cylinder, the first brush strip is located inside the first cleaning frame and abuts against the outer wall of the slag removal filter cylinder, and the transmission assembly is mounted on the rotating shaft and drives the first cleaning frame to rotate with the rotating shaft.

[0008] By adopting the above technical solution, kitchen wastewater enters the slag removal filter cylinder through the feed pipe. The rotating shaft drives the spiral blades to rotate, and the spiral blades move the kitchen waste inside the slag removal filter cylinder. During the movement, the wastewater in the kitchen waste flows out from the filter holes of the slag removal filter cylinder and is discharged from the discharge pipe. The kitchen waste is then discharged from the slag discharge pipe. When the spiral blades rotate, they drive the spiral brush to rotate, which cleans the inner wall of the slag removal filter cylinder. At the same time, the rotating shaft drives the first cleaning frame to rotate on the slag removal filter cylinder through the transmission assembly. The first cleaning frame drives the first brush strip to move and clean the outer wall of the slag removal filter cylinder. This makes it difficult for grease in the kitchen waste to adhere to the inner and outer walls of the slag removal filter cylinder, thus making the slag removal filter cylinder less prone to clogging by kitchen waste and improving the separation effect of wastewater in kitchen waste.

[0009] Preferably, the transmission assembly includes a drive gear, a first transmission gear, a transmission rod, a second transmission gear, and a driven gear ring. The drive gear is fixedly mounted on the rotating shaft, and the driven gear ring is fixedly mounted on the first cleaning frame. The first transmission gear meshes with the drive gear, the second transmission gear meshes with the driven gear ring, and the transmission rod connects the first transmission gear and the second transmission gear.

[0010] By adopting the above technical solution, when the rotating shaft rotates, it drives the first transmission gear to rotate through the drive gear. The first transmission gear drives the second transmission gear to rotate through the transmission rod. The second transmission gear then drives the first cleaning frame to rotate through the driven gear ring, thereby enabling the first brush strip to clean the outer wall of the slag removal filter cartridge.

[0011] Preferably, the first cleaning frame includes two first rotating rings and multiple first connecting rods. The two first rotating rings are rotatably sleeved on the slag removal filter cylinder. The drive gear is fixedly sleeved on one of the first rotating rings. The two ends of the first connecting rods are respectively fixedly connected to the two first rotating rings. The multiple first connecting rods are arranged at intervals along the circumference of the first rotating rings. The first brush strip is fixedly arranged on the side wall of the first connecting rod near the slag removal filter cylinder. A first water passage area is formed between two adjacent first connecting rods for sewage to drip into the tank.

[0012] By adopting the above technical solution, the driven gear ring drives the first rotating ring to rotate, and the first rotating ring drives multiple first connecting rods to move, thereby driving multiple first brush strips to move and clean the outer wall of the slag removal filter cartridge. During the cleaning process of the first cleaning frame, the sewage dripping from the slag removal filter cartridge drips into the box body through the first water passage area, so that the sewage will not accumulate in the first cleaning frame.

[0013] Preferably, a heating lamp is provided on the inner wall of the chamber, and the heating lamp is directed towards the slag removal filter cartridge.

[0014] By adopting the above technical solution, the heating lamp heats the grease inside the grease removal filter cartridge, thereby making it less likely for the grease to adhere to the filter cartridge.

[0015] Preferably, the rotating shaft is provided with multiple nozzles, a water supply channel communicating with the multiple nozzles is opened inside the rotating shaft, and a water supply pipe communicating with the water supply channel is passed through the housing.

[0016] By adopting the above technical solution, after the kitchen waste is screened, the water supply pipe injects water into the nozzle through the water supply channel, and the nozzle sprays water towards the inner wall of the slag removal filter cartridge, which facilitates the cleaning of the inner wall of the slag removal filter cartridge.

[0017] Preferably, the box body is provided with a partition, which divides the inner cavity of the box body into a first chamber and a second chamber. The slag removal filter cartridge is located in the first chamber. The two ends of the slag removal filter cartridge are fixedly connected to the inner wall of the box body and the partition, respectively. The inner cavity of the slag removal filter cartridge is connected to the second chamber, and the second chamber is located above the slag discharge pipe.

[0018] By adopting the above technical solution, the sewage discharged from the slag removal filter cartridge drips into the first chamber, and the kitchen waste in the slag removal filter cartridge is transported to the second chamber and falls from the second chamber into the slag discharge pipe. The partition separates the inside of the box, so that the kitchen waste and sewage can be separated when discharged.

[0019] Preferably, the slag removal filter cartridge is provided with a top-opening slag removal filter box below the feed pipe, and the slag removal filter box is connected to the slag removal filter cartridge.

[0020] By adopting the above technical solution, kitchen wastewater first flows into the slag removal filter box from the feed pipe, and then flows into the slag removal filter cartridge from the slag removal filter box. The slag removal filter box is used to initially store kitchen waste, thereby reducing the situation where kitchen waste clogs the slag removal filter cartridge due to a large amount of kitchen wastewater flowing in in a short period of time.

[0021] Preferably, a second cleaning mechanism is provided on the outside of the slag removal filter cylinder and below the slag removal filter box. The second cleaning mechanism includes a second cleaning frame, a driving component, and a second brush bar. The second cleaning frame is reciprocated and positioned below the slag removal filter cylinder. The second brush bar is positioned inside the second cleaning frame and abuts against the outer wall of the slag removal filter cylinder. The driving component is positioned on the housing and the first cleaning frame and drives the second cleaning frame to reciprocate.

[0022] By adopting the above technical solution, when the first cleaning frame rotates and drives the first brush strip to clean the outer wall of the slag removal filter cylinder, the first cleaning frame drives the second cleaning frame to swing back and forth below the slag removal filter cylinder through the drive component. The second cleaning frame drives the second brush strip to move and clean the outer wall of the slag removal filter cylinder located below the slag removal filter box, thereby making the cleaning of the outer wall of the slag removal filter cylinder more comprehensive.

[0023] Preferably, the second cleaning frame includes two second rotating rings and multiple second connecting rods. The two second rotating rings are respectively rotatably sleeved on both sides of the slag removal filter cylinder located in the slag removal filter box. The two driving ends of the driving assembly are respectively connected to the second rotating rings and the second connecting rods. The two ends of the second connecting rods are respectively fixedly connected to the two second rotating rings. The multiple second connecting rods are arranged at intervals along the circumference of the second rotating rings in the lower half of the first rotating ring. The second brush strip is fixedly arranged on the side wall of the second connecting rod near the slag removal filter cylinder, and a second water passage area is formed between two adjacent second connecting rods for sewage to drip into the box.

[0024] By adopting the above technical solution, the first cleaning frame drives the second rotating ring to rotate through one drive end of the drive component. The second rotating ring drives multiple second connecting rods to move in one direction. The second drive end of the drive component then drives the second connecting rods to move in another direction, realizing the reciprocating swing of the second cleaning frame. This enables multiple second brush strips to move and clean the outer wall of the slag removal filter cartridge. During the rotation and cleaning process of the second cleaning frame, the sewage dripping from the slag removal filter cartridge drips into the box through the second water passage area, thus preventing sewage from accumulating in the second cleaning frame.

[0025] Preferably, the drive assembly includes an elastic band, a stop block, a lever, a limiting block, and an elastic reset member. The stop block is disposed on a second rotating ring near the first cleaning frame. The lever is rotatably disposed at one end of the first cleaning frame near the second cleaning frame, with its end resting on the stop block. The two ends of the elastic reset member are respectively connected to the side wall of the lever and the first cleaning frame. The limiting block is disposed on the first cleaning frame and used to limit the lever. When the first cleaning frame moves, the elastic reset member pulls the lever, and the lever... The stop block drives the second cleaning frame to rotate. When the second cleaning frame rotates and abuts against the slag removal filter box, the lever rotates and disengages from the stop block. The elastic reset component pulls the lever to rotate and abut against the limit block to reset. One end of the elastic band is connected to the second connecting rod, and the other end is connected to the inner wall of the box. When the lever drives the first cleaning frame to move, the elastic band stretches. When the lever disengages from the overlap state, the elastic band contracts and drives the second cleaning frame to move in the same direction. After the first cleaning frame rotates one revolution, the lever again drives the second cleaning frame to move through the stop block.

[0026] By adopting the above technical solution, the lever and the stop block are used to overlap, so that when the first cleaning frame rotates, it can drive the second cleaning frame to rotate together. The elastic reset component is used to allow the lever and the stop block to disengage and the lever to rotate back to its original position, so that the lever can overlap the stop block again. When the elastic band causes the lever and the stop block to disengage, the second cleaning frame can move in the opposite direction, so that the second cleaning frame can swing back and forth.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By employing a spiral brush and a first cleaning mechanism, the spiral blades rotate, driving the spiral brush to rotate. The spiral brush cleans the inner wall of the slag removal filter cylinder. The rotating shaft drives the first cleaning frame to rotate on the slag removal filter cylinder through the transmission assembly. The first cleaning frame drives the first brush strip to move and clean the outer wall of the slag removal filter cylinder. This makes it difficult for grease in kitchen waste to adhere to the inner and outer walls of the slag removal filter cylinder, thus making the slag removal filter cylinder less prone to clogging by kitchen waste and improving the effect of separating wastewater from kitchen waste.

[0029] 2. By adopting a second cleaning mechanism, the first cleaning frame drives the second cleaning frame to swing back and forth below the slag removal filter cartridge through the drive component. The second cleaning frame drives the second brush strip to move and clean the outer wall of the slag removal filter cartridge located below the slag removal filter box, thereby making the cleaning of the outer wall of the slag removal filter cartridge more comprehensive.

[0030] 3. By using partitions to separate the interior of the container, kitchen waste and sewage can be separated during discharge. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application discloses a spiral slag removal device that is easy to clean.

[0041] Reference Figure 1 and 2 A spiral slag removal device that is easy to clean includes a housing 1. A partition 14 is fixedly installed in the vertical direction inside the housing 1, dividing the inside of the housing 1 into a first chamber 15 and a second chamber 16. A slag removal filter cylinder 6 is fixedly installed in the first chamber 15 of the housing 1. The axis of the slag removal filter cylinder 6 makes an angle of 30° with the horizontal plane. The lower end of the slag removal filter cylinder 6 is fixedly connected to the inner wall of the housing 1, and the higher end is fixedly connected to the partition 14. The higher end of the inner cavity of the slag removal filter cylinder 6 communicates with the second chamber 16.

[0042] Reference Figure 2 and 3 A slag removal filter box 17 is fixedly installed on the top of the lower end of the slag removal filter cartridge 6. The top of the slag removal filter box 17 is open, and its bottom is connected to the slag removal filter cartridge 6. A feed pipe 7 is installed through the top of the housing 1 above the slag removal filter box 17. The top end of the feed pipe 7 is connected to the kitchen drainage pipe, and the bottom end extends into the open end of the slag removal filter box 17. Kitchen wastewater first enters the slag removal filter box 17 through the feed pipe 7, and then enters the slag removal filter cartridge 6 from the slag removal filter box 17.

[0043] Reference Figure 1 and 2A rotating shaft 2 is rotatably mounted inside the housing 1. The rotating shaft 2 is coaxially mounted inside the slag removal filter cartridge 6, with its higher end passing through the second chamber 16 and exiting the housing 1. A reducer 22 is fixedly mounted on the housing 1. A motor 23 is installed at the input end of the reducer 22, and the output end of the reducer 22 is fixedly connected to the end of the rotating shaft 2 that extends into the housing 1. The motor 23 drives the rotating shaft 2 to rotate inside the slag removal filter cartridge 6 via the reducer 22.

[0044] Reference Figure 2 and 3 A spiral blade 3 is fixedly installed on the rotating shaft 2. The rotating shaft 2 drives the spiral blade 3 to rotate, and the spiral blade 3 drives the kitchen waste in the slag removal filter cylinder 6 to move upward. During the movement, the sewage in the kitchen waste drips from the filter holes of the slag removal filter cylinder 6 into the first chamber 15. A discharge pipe 8 connected to the first chamber 15 is installed at the bottom of the box body 1. The sewage in the first chamber 15 is discharged from the box body 1 through the discharge pipe 8.

[0045] The housing 1 is located at the bottom of the second chamber 16 and is equipped with a slag discharge pipe 9 that communicates with the second chamber 16. The spiral blades 3 drive the kitchen waste in the slag removal filter cylinder 6 to move upwards. The kitchen waste falls from the top of the slag removal filter cylinder 6 into the second chamber 16, then from the second chamber 16 into the slag discharge pipe 9, and finally is discharged from the slag discharge pipe 9. At the same time, the partition 14 blocks the falling kitchen waste, preventing it from falling into the first chamber 15.

[0046] Three heating lamps 18 are fixedly installed on both inner side walls along the width direction of the housing 1, with the heating lamps 18 pointing towards the slag removal filter cartridge 6. The heating lamps 18 heat the slag removal filter cartridge 6, thereby heating the grease inside the slag removal filter cartridge 6, making it less likely for the grease to adhere to the slag removal filter cartridge 6.

[0047] Reference Figure 3 and 4 A spiral brush 10 is fixedly installed on the side wall of the spiral blade 3 near the lower end of the slag removal filter cylinder 6, with the end of the spiral brush 10 abutting against the inner side wall of the slag removal filter cylinder 6. In this application, the spiral brush 10 can be a spiral wire brush. When the spiral blade 3 moves the kitchen waste inside the slag removal filter cylinder 6, the spiral blade 3 simultaneously drives the spiral brush 10 to rotate. The spiral brush 10 cleans the inner side wall of the slag removal filter cylinder 6, making it difficult for oil stains in the kitchen waste to adhere to the inner wall of the slag removal filter cylinder 6, thereby making it less likely for kitchen waste to clog the filter holes of the slag removal filter cylinder 6 and improving the effect of wastewater separation in the kitchen waste.

[0048] Multiple nozzles 19 are fixedly installed at intervals along the circumference and axial direction on the outer surface of the rotating shaft 2. A water supply channel 20 is opened inside the rotating shaft 2, and the water supply channel 20 is connected to each nozzle 19. A water supply pipe 21 connected to the water supply channel 20 is installed at the bottom end of the rotating shaft 2 through a rotary joint. After the kitchen waste is screened, the water supply pipe 21 injects water into the nozzles 19 through the water supply channel 20. The nozzles 19 spray water toward the inner wall of the slag removal filter cylinder 6, thereby facilitating the spiral brush 10 to clean the inner wall of the slag removal filter cylinder 6.

[0049] Reference Figure 2 and 5 The upper half of the slag removal filter cylinder 6 is rotatably fitted with a first cleaning mechanism 4, while the lower half of the slag removal filter cylinder 6, located below the slag removal filter box 17, is reciprocally mounted with a second cleaning mechanism 5. The first cleaning mechanism 4 cleans the outer wall of the upper half of the slag removal filter cylinder 6, and the second cleaning mechanism 5 cleans the outer wall of the bottom of the lower half of the slag removal filter cylinder 6. This prevents oil stains from adhering to the outer wall of the slag removal filter cylinder 6, thus preventing food waste from clogging the filter holes and further improving the wastewater separation effect.

[0050] Reference Figure 5 and 6 Specifically, the first cleaning mechanism 4 includes a first cleaning frame 41, a transmission assembly 42, and six first brush strips 43. The first cleaning frame 41 is rotatably mounted on the slag removal filter cylinder 6, and the six first brush strips 43 are fixedly installed inside the first cleaning frame 41 and abut against the outer wall of the slag removal filter cylinder 6. The transmission assembly 42 is mounted on the rotating shaft 2 and drives the first cleaning frame 41 to rotate together with the rotating shaft 2. In this application, the first brush strips 43 can be selected as wire brush strips.

[0051] The first cleaning frame 41 includes two first rotating rings 411 and six first connecting rods 412. The two first rotating rings 411 are rotatably mounted on the filter cake sleeve via bearings. The two ends of the first connecting rods 412 are fixedly connected to the side walls of the two first rotating rings 411 that are close to each other. The first connecting rods 412 are installed along the axial direction of the rotating shaft 2. The six first connecting rods 412 are installed at equal intervals along the circumference of the first rotating rings 411. A first water passage zone 11 for sewage dripping is formed between each two adjacent first connecting rods 412. The six first brush strips 43 are fixedly installed on the side walls of the six first connecting rods 412 that are close to the filter cake 6.

[0052] Reference Figure 2 , 56. The transmission assembly 42 includes a drive gear 421, a first transmission gear 422, a transmission rod 423, a second transmission gear 424, and a driven gear ring 425. The drive gear 421 is fixedly mounted on one end of the bearing located within the second chamber 16, and the driven gear ring 425 is fixedly sleeved on the outer wall of the first rotating ring 411 near the end of the drive gear 421. A fixing rod 13 is fixedly mounted on the top wall of the inner cavity of the housing 1. The transmission rod 423 is rotatably mounted on the bottom end of the fixing rod 13 via a bearing, and the transmission rod 423 passes through the partition 14. The first transmission gear 422 and the second transmission gear 424 are respectively fixedly mounted on both ends of the transmission rod 423, and the first transmission gear 422 meshes with the drive gear 421, while the second transmission gear 424 meshes with the driven gear ring 425.

[0053] The rotating shaft 2 drives the first transmission gear 422 to rotate via the drive gear 421. The first transmission gear 422 drives the second transmission gear 424 to rotate via the transmission rod 423. The second transmission gear 424 drives the first rotating ring 411 to rotate via the driven gear ring 425. The first rotating ring 411 then drives the first brush strip 43 to move via the first connecting rod 412. This allows the first cleaning mechanism 4 to rotate together with the rotating shaft 2. The first brush strip 43 works in conjunction with the spiral brush 10 to clean the inner and outer walls of the slag removal filter cartridge 6 simultaneously, making the oil stains on the slag removal filter cartridge 6 more thoroughly cleaned.

[0054] Reference Figure 5 and 6 Specifically, the second cleaning mechanism 5 includes a second cleaning frame 51, a drive assembly 52, and three second brush strips 53. The second cleaning frame 51 is reciprocated and oscillates on the slag removal filter cylinder 6 and is located below the slag removal filter box 17. The three second brush strips 53 are fixedly installed inside the second cleaning frame 51 and abut against the outer wall of the slag removal filter cylinder 6. The drive assembly 52 is installed on the first rotating ring 411 and the inner wall of the housing 1 and drives the second cleaning frame 51 to reciprocate on the slag removal filter cylinder 6. In this application, the second brush strips 53 can be selected as wire brush strips.

[0055] The second cleaning frame 51 includes two second rotating rings 511 and three second connecting rods 512. The two second rotating rings 511 are rotatably sleeved on the filter cake sleeve via bearings and located on both sides of the filter cake 6. The two ends of the second connecting rods 512 are fixedly connected to the side walls of the two second rotating rings 511 that are close to each other. The second connecting rods 512 are installed along the axial direction of the rotating shaft 2. The three second connecting rods 512 are installed at equal intervals along the circumference of the second rotating rings 511 in the lower half of the second conversion. A second water passage zone 12 for sewage dripping is formed between each two adjacent second connecting rods 512, and the three second brush strips 53 are fixedly installed on the side walls of the three second connecting rods 512 that are close to the filter cake 6.

[0056] Reference Figure 6 and 7The drive assembly 52 includes a stop block 522, a lever 523, a limit block 524, an elastic reset member 525, and two elastic bands 521. One end of the two elastic bands 521 is fixedly connected to both ends of the second connecting rod 512, and the other end of the two elastic bands 521 is fixedly connected to the inner side wall of the housing 1. The elastic bands 521 can drive the second cleaning frame 51 to rotate through the second pull rod, thereby cleaning the outer wall of the slag removal filter cylinder 6 in one direction.

[0057] The lever 523 is rotatably mounted on the side wall of the first rotating ring 411 near the second cleaning frame 51. One end of the elastic reset member 525 is fixedly connected to the side of the lever 523 away from the first rotating ring 411, and the other end is fixedly connected to the first rotating ring 411. The limiting block 524 has a triangular cross-section and is fixedly mounted on the side wall of the first rotating ring 411 near the lever 523, and the elastic reset member 525 pulls the lever 523 to abut against the limiting block 524. In this application, the elastic reset member 525 can be a spring. The use of the elastic reset member 525 and the limiting block 524 ensures that the lever 523 is always perpendicular to the end face of the first rotating ring 411, and when the external pushing force is greater than the elastic force of the elastic reset member 525, the lever 523 can rotate away from the limiting block 524.

[0058] The stop block 522 is fixedly installed on the outer wall of the second rotating ring 511 near the first cleaning frame 41. When the lever 523 is perpendicular to the end face of the first rotating ring 411, the end of the lever 523 abuts against the stop block 522. When the rotating shaft 2 drives the first cleaning frame 41 to rotate, the first rotating ring 411 can push the second rotating ring 511 to rotate together with the first rotating ring 411 through the lever 523 and the stop block 522. The second rotating ring 511 drives the second brush strip 53 to move through the second connecting rod 512, thereby cleaning the outer wall of the slag removal filter cylinder 6 in another direction.

[0059] The elastic force of the elastic reset component 525 is much greater than that of the elastic band 521. When the first rotating ring 411 drives the second rotating ring 511 to rotate via the lever 523 and the stop block 522, the second rotating ring 511 stretches the elastic band 521 via the second pull rod. After the second cleaning frame 51 rotates and abuts against the slag removal filter box 17, the second rotating ring 511 can no longer rotate. As the first rotating ring 411 continues to rotate, the lever 523 rotates and contacts the stop block 522. At this time, the elastic band contracts and pulls the second cleaning frame 51 to rotate in the opposite direction. The elastic reset component 525 pulls the lever 523 to rotate and abut against the limit block 524 to reset. After the first rotating ring 411 rotates one revolution, the lever 523 drives the first cleaning frame 41 to rotate again via the stop block 522, thus realizing the reciprocating swing of the first cleaning frame 41.

[0060] The implementation principle of this application embodiment is as follows: kitchen wastewater first enters the slag removal filter box 17 through the feed pipe 7, and then enters the slag removal filter cylinder 6 from the slag removal filter box 17. The motor 23 can drive the rotating shaft 2 to rotate in the slag removal filter cylinder 6 through the reducer 22. The rotating shaft 2 drives the kitchen waste to move through the spiral blade 3. The sewage in the kitchen waste drips from the filter hole of the slag removal filter cylinder 6 into the first chamber 15 and is discharged from the discharge pipe 8. The kitchen waste falls from the top of the slag removal filter cylinder 6 into the second chamber 16 and is discharged from the slag discharge pipe 9. When the spiral blade 3 moves the kitchen waste inside the slag removal filter cylinder 6, the spiral blade 3 simultaneously drives the spiral brush 10 to rotate. The spiral brush 10 cleans the inner wall of the slag removal filter cylinder 6. At the same time, the rotating shaft 2 drives the first cleaning frame 41 to rotate together through the transmission assembly 42, so that the first brush strip 43 cleans the outer wall of the slag removal filter cylinder 6. The first cleaning frame 41 drives the second cleaning frame 51 to swing back and forth through the drive assembly 52, so that the first brush strip 43 cleans the outer wall of the slag removal filter cylinder 6. As a result, the oil stains in the kitchen waste are less likely to adhere to the inner wall of the slag removal filter cylinder 6, and the kitchen waste is less likely to clog the filter holes of the slag removal filter cylinder 6, thus improving the effect of wastewater separation in the kitchen waste.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
