Wastewater treatment device and process for ink and paint production

Abstract

The present invention relates to the technical field of wastewater treatment equipment, and discloses a wastewater treatment device and process for ink and paint production, comprising a base, wherein an inner wall of a through hole of the base is fixedly connected to a water inlet pipe, and an outer wall of the water inlet pipe is rotatably connected to a treatment pipe. As the treatment pipe rotates, a accommodating square pipe filled with sewage and flocs will reach the top of the treatment pipe, and a rotating plate will completely block the accommodating square pipe. The accommodating square pipe, the sliding square pipe, the U-shaped slide plate and the fixed plate will form a closed space, so that the internal sewage and flocs are in a relatively stable state. When the sliding square pipe reaches the top, the roller will drive the sliding square pipe to slide downward along the inner wall of the accommodating square pipe, so that a gap is formed between the U-shaped slide plate and the sliding square pipe. At this time, the sliding square pipe moves downward, but the total amount of internal sewage remains unchanged. Part of the sewage will carry the flocs and be discharged outward through the gap between the U-shaped slide plate and the sliding square pipe, thereby removing most of the flocs in the sewage.

Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment equipment, in particular to a wastewater treatment device and process for ink and coating production. Background Art

[0002] In the production process of water-based ink printing technology, the ink needs to be replaced and the printing equipment needs to be cleaned, which will produce a certain amount of ink wastewater. The conventional treatment process is as follows: first add a decolorizer for decolorization, then add polyaluminum chloride to allow the impurities in the water to flocculate, and finally add cationic polyacrylamide. After the agent and sewage are fully mixed, the inside will condense into flocs.

[0003] However, the flocculent materials are loose. When conventional filters are used for separation, the filters with larger holes will break the floccules and affect the separation effect. The filters with smaller holes will be clogged. Even if scrapers are used, the inner diameter of the holes will still be clogged. To solve the above problems, the following solutions are proposed. Summary of the Invention

Before use, the base is installed in the desired position, and then, it is ensured that the water inlet pipe and the external water pipe are in a connected state. The staff can connect multiple devices end to end according to the floc content contained in the sewage to extend the processing time.

[0008] Preferably, the filter assembly also includes a support frame fixedly connected to the outer wall of the accommodating square tube, the end of the support frame away from the accommodating square tube is fixedly connected to the outer wall of the fixed plate, and a roller is rotatably connected to the side wall of the sliding square tube. The filter assembly also includes four springs one fixedly connected to the outer wall of the support frame, the other end of the four springs one is fixedly connected to the outer wall of the sliding square tube, and a special-shaped ring one is fixedly connected to the top of the base. When the sewage containing flocs enters the interior of the treatment pipe through the water inlet pipe, first ensure that the horizontal position of the sewage is not higher than the center point of the treatment pipe, and then turn on the power of the motor. The motor drives the gear ring and the treatment pipe to rotate clockwise through the driving gear, and the rotating treatment pipe will drive the six accommodating square tubes to rotate at the same time.

[0009] Preferably, the outer wall of the special-shaped ring is rotatably connected to the outer walls of the six rollers, the inner wall of the accommodating square tube is fixedly connected with a discharge assembly, and the side wall of the sliding square tube is fixedly connected with a collection assembly. Figure 9 When the position F is in the middle, the rolling column is affected by the change of the outer wall of the second special-shaped ring, causing the rotating plate to rotate, showing as Figure 7 In the middle G state, the sewage inside the treatment pipe passes through the gap between the rotating plate and the accommodating square pipe and enters the accommodating square pipe, the sliding square pipe and the U-shaped slide plate; and as the treatment pipe rotates, the accommodating square pipe filled with sewage and flocs will reach the top of the treatment pipe. At this time, due to the pressure generated by the sewage flowing outward through the gap between the rotating plate and the accommodating square pipe and the dead weight of the rotating plate, the rotating plate will completely block the accommodating square pipe, presenting the following Figure 7 In the middle F state, the accommodating square tube, the sliding square tube, the U-shaped slide plate and the fixed plate will form a closed space, so that the internal sewage and flocs are in a relatively stable state. When the sliding square tube reaches the top, the roller will enter the flat position of the special-shaped ring. At this time, the roller will drive the sliding square tube to slide downward along the inner wall of the accommodating square tube, so that a gap is formed between the U-shaped slide plate and the sliding square tube, showing as follows Figure 6 The sliding square tube moves downward, but the total amount of sewage inside remains unchanged. When the sliding square tube moves downward, part of the sewage will carry flocs and be discharged outward through the gap between the U-shaped slide plate and the sliding square tube. Through the application of the above components, most of the flocs can be removed while avoiding the problem of filter clogging, which requires frequent replacement and cleaning.

[0010] Preferably, the discharge assembly includes a fixed plate 1 fixedly connected to the side wall of the accommodating square tube, a hydraulic telescopic rod 1 is fixedly connected to the side wall of the fixed plate 1, and an L-shaped plate is fixedly connected to the end of the hydraulic telescopic rod 1 away from the fixed plate 1.

[0012] Preferably, the discharge component also includes a transmission tube connected to a side wall of the hydraulic telescopic rod, and the end of the transmission tube away from the hydraulic telescopic rod one is connected to the hydraulic telescopic rod two, and the side wall of the hydraulic telescopic rod two is fixedly connected to the inner wall of the accommodating square tube, and the characteristic of the above-mentioned special-shaped ring one controlling the sliding of the sliding square tube through the roller is utilized, and a discharge component is provided inside the equipment, wherein, after the accommodating square tube completes discharging at the highest position, as the processing tube rotates, the roller is gradually reset under the push of the spring one, and the rolling column will enter the protruding position of the special-shaped ring two again, so that the rolling column drives the hydraulic telescopic rod one to extend through the L-shaped plate along the protruding position of the special-shaped ring two, and the extended hydraulic telescopic rod one will extract the liquid inside the hydraulic telescopic rod two through the transmission tube, so that the hydraulic telescopic rod two contracts, and the contracted hydraulic telescopic rod two forces the rotating plate to rotate, so that the rotating plate moves from Figure 7 The state F in the middle changes to the state G. At this time, the gap between the rotating plate and the accommodating square tube will force the sewage to fall downward through the gap and re-collect inside the sewage in the treatment pipe. At this time, the falling sewage will impact the sewage inside the treatment pipe, causing the sewage inside the treatment pipe to carry more flocs and flow to the position G, thereby improving the collection efficiency of the equipment.

[0014] Preferably, the collecting assembly includes a fixed bracket fixedly connected to the side wall of the sliding square tube, a collecting box fixedly connected to the inner wall of the fixed bracket, a counterweight slider slidably connected to the inner wall of the collecting box, and a accommodating box fixedly connected to the top of the base. Taking advantage of the fact that the position of the accommodating square tube changes with the change of the installation groove, a collecting assembly is provided inside the equipment. When the accommodating square tube reaches the highest position and pours out the sewage, the sewage will be poured into the collecting box. At this time, the collecting box will collect the sewage sprayed out, and as the position of the accommodating square tube changes, the sewage inside the collecting box will gradually tilt and pour downward, and finally enter the accommodating box to realize the overall collection of the sewage. In addition, due to the change in the position of the collecting box, when the collecting box reaches the lowest part, the counterweight slider will slide downward along the inner wall of the collecting box, presenting a Figure 10 The counterweight slider is in the middle H state, and during the sliding process, it will scrape the inner wall of the collection box to remove the impurities remaining inside the collection box.

[0015] A process for using a wastewater treatment device for ink and coating production includes the following steps:

[0016] S1: Advance preparation: Workers can connect multiple devices end to end based on the floc content in the sewage to extend the processing time;

[0017] S2: Connect the water pipe: Before use, install the base in the desired position, and then ensure that the water inlet pipe and the external water pipe are connected;

[0018] S3: Turn on the power: When the sewage containing flocs enters the treatment pipe through the water inlet pipe, first ensure that the horizontal position of the sewage is not higher than the center point of the treatment pipe, and then turn on the power of the motor.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention utilizes the characteristic that flocs float on the water surface, and a treatment mechanism and a filter assembly are provided inside the device. Before use, the base is installed in the desired position, and then the water inlet pipe and the external water pipe are ensured to be connected. The staff can connect multiple devices end to end according to the floc content contained in the sewage, thereby extending the processing time. When the sewage containing flocs enters the treatment pipe through the water inlet pipe, the horizontal position of the sewage is first ensured to be no higher than the center point of the treatment pipe, and then the power supply of the motor is turned on. The motor drives the gear ring and the treatment pipe to rotate clockwise through the driving gear, and the rotating treatment pipe will drive the six accommodating square pipes to rotate simultaneously. When the accommodating square pipe is in Figure 9 When the position F is in the middle, the rolling column is affected by the change of the outer wall of the second special-shaped ring, causing the rotating plate to rotate, showing as Figure 7 In the middle G state, the sewage inside the treatment pipe passes through the gap between the rotating plate and the accommodating square pipe and enters the accommodating square pipe, the sliding square pipe and the U-shaped slide plate; and as the treatment pipe rotates, the accommodating square pipe filled with sewage and flocs will reach the top of the treatment pipe. At this time, due to the pressure generated by the sewage flowing outward through the gap between the rotating plate and the accommodating square pipe and the dead weight of the rotating plate, the rotating plate will completely block the accommodating square pipe, presenting the following Figure 7 In the middle F state, the accommodating square tube, the sliding square tube, the U-shaped slide plate and the fixed plate will form a closed space, so that the internal sewage and flocs are in a relatively stable state. When the sliding square tube reaches the top, the roller will enter the flat position of the special-shaped ring. At this time, the roller will drive the sliding square tube to slide downward along the inner wall of the accommodating square tube, so that a gap is formed between the U-shaped slide plate and the sliding square tube, showing as follows Figure 6 The sliding square tube moves downward, but the total amount of sewage inside remains unchanged. When the sliding square tube moves downward, part of the sewage will carry flocs and be discharged outward through the gap between the U-shaped slide plate and the sliding square tube. Through the application of the above components, most of the flocs can be removed while avoiding the problem of filter clogging, which requires frequent replacement and cleaning.

[0021] (2) The present invention utilizes the characteristic that the special-shaped ring 1 controls the sliding of the sliding square tube through the roller, and a discharge assembly is provided inside the equipment, wherein after the square tube is discharged at the highest position, as the processing tube rotates, the roller is gradually reset under the push of the spring 1, and the rolling column will enter the protruding position of the special-shaped ring 2 again, so that the rolling column drives the hydraulic telescopic rod 1 to extend along the protruding position of the special-shaped ring 2 through the L-shaped plate, and the extended hydraulic telescopic rod 1 will extract the liquid inside the hydraulic telescopic rod 2 through the transmission pipe, so that the hydraulic telescopic rod 2 will contract, and the contracted hydraulic telescopic rod 2 forces the rotating plate to rotate, so that the rotating plate moves from Figure 7 The state F in the middle changes to the state G. At this time, the gap between the rotating plate and the accommodating square tube will force the sewage to fall downward through the gap and re-collect inside the sewage in the treatment pipe. At this time, the falling sewage will impact the sewage inside the treatment pipe, causing the sewage inside the treatment pipe to carry more flocs and flow to the position G, thereby improving the collection efficiency of the equipment.

[0022] (3) The present invention utilizes the characteristics that the rotating plate and the fixed plate are extended by the influence of the special-shaped ring 1 and the special-shaped ring 2, such as Figure 9 When the accommodating square tube reaches position F, the special-shaped ring 1 is open and the fixed plate is in a closed state. When the accommodating square tube reaches position A, the special-shaped ring 1 is completely closed, and a gap will be formed between the fixed plate and the sliding square tube. When the accommodating square tube reaches position B, the gap between the fixed plate and the sliding square tube has not been completely closed, and the special-shaped ring 1 is also in an open state, so that the sewage inside the accommodating square tube is re-mixed with the sewage inside the treatment tube. When the other positions are used, the special-shaped ring 1 and the fixed plate are in a closed state. Through the application of the above components, the orderliness of the equipment in treating sewage is guaranteed when it is in use.

[0023] (4) The present invention utilizes the characteristic that the position of the above-mentioned accommodating square tube changes with the change of the installation slot, and a collection component is provided inside the device. When the accommodating square tube reaches the highest position and pours out the sewage, the sewage will be poured into the collection box. At this time, the collection box will collect the sewage sprayed out, and as the position of the accommodating square tube changes, the sewage inside the collection box will gradually tilt and pour downward, and finally enter the interior of the accommodating box, realizing the overall collection of the sewage; in addition, due to the change in the position of the collection box, when the collection box reaches the lowest part, the counterweight slider will slide downward along the inner wall of the collection box, presenting the following Figure 10 The counterweight slider is in the middle H state, and during the sliding process, it will scrape the inner wall of the collection box to remove the impurities remaining inside the collection box.

Before use, the base 1 is installed in the desired position, and then, it is ensured that the water inlet pipe 11 is connected to the external water pipe. The staff can connect multiple devices end to end according to the floc content contained in the sewage to extend the processing time.

[0044] The filter assembly 3 also includes a support frame 35 fixedly connected to the outer wall of the accommodating square tube 31, and one end of the support frame 35 away from the accommodating square tube 31 is fixedly connected to the outer wall of the fixed plate 34, and a roller 36 is rotatably connected to the side wall of the sliding square tube 32. The filter assembly 3 also includes four springs 37 fixedly connected to the outer wall of the support frame 35, and the other ends of the four springs 37 are fixedly connected to the outer wall of the sliding square tube 32. A special-shaped ring 38 is fixedly connected to the top of the base 1. When the sewage containing flocs enters the treatment pipe 12 through the water inlet pipe 11, first ensure that the horizontal position of the sewage is not higher than the center point of the treatment pipe 12, and then turn on the power of the motor 22. The motor 22 drives the gear ring 24 and the treatment pipe 12 to rotate clockwise through the driving gear 23, and the rotating treatment pipe 12 will drive the six accommodating square tubes 31 to rotate at the same time.

[0045] The outer wall of the special-shaped ring 38 is rotatably connected to the outer wall of the six rollers 36. The inner wall of the accommodating square tube 31 is fixedly connected with the discharge component 4. The side wall of the sliding square tube 32 is fixedly connected with the collection component 5. When the accommodating square tube 31 is in Figure 9 When the position F is in the middle, the rolling column 44 is affected by the change of the outer wall of the special-shaped ring 49, causing the rotating plate 48 to rotate, showing as Figure 7 In the middle G state, the sewage inside the treatment pipe 12 passes through the gap between the rotating plate 48 and the accommodating square pipe 31 and enters the accommodating square pipe 31, the sliding square pipe 32 and the U-shaped slide plate 33; and as the treatment pipe 12 rotates, the accommodating square pipe 31 filled with sewage and flocs will reach the top of the treatment pipe 12. At this time, due to the pressure generated by the sewage flowing outward through the gap between the rotating plate 48 and the accommodating square pipe 31 and the deadweight of the rotating plate 48, the rotating plate 48 will completely block the accommodating square pipe 31, presenting as shown in the figure. Figure 7 In the state of middle F, the accommodating square tube 31, the sliding square tube 32, the U-shaped slide 33 and the fixed plate 34 will form a closed space, so that the internal sewage and flocs are in a relatively stable state. When the sliding square tube 32 reaches the top, the roller 36 will enter the gentle position of the special-shaped ring 1 38. At this time, the roller 36 will drive the sliding square tube 32 to slide downward along the inner wall of the accommodating square tube 31, so that a gap is formed between the U-shaped slide 33 and the sliding square tube 32, showing as follows Figure 6In this state, the sliding square tube 32 moves downward, but the total amount of sewage inside remains unchanged. When the sliding square tube 32 moves downward, part of the sewage will carry flocs and be discharged outward through the gap between the U-shaped slide plate 33 and the sliding square tube 32. Through the application of the above components, while removing most of the flocs, the problem of filter screen clogging and the need for frequent replacement and cleaning can be avoided.

[0046] For example 2, please refer to Figure 4 - Figure 12 The present invention is a wastewater treatment device for ink and paint production. On the basis of embodiment 1, the discharge component 4 includes a fixed plate 41 fixedly connected to the side wall of the accommodating square tube 31, a hydraulic telescopic rod 42 is fixedly connected to the side wall of the fixed plate 41, and an L-shaped plate 43 is fixedly connected to the end of the hydraulic telescopic rod 42 away from the fixed plate 41.

[0047] The discharge assembly 4 also includes a second spring 45 fixedly connected to the side wall of the L-shaped plate 43, and a rolling column 44 is rotatably connected to the side wall of the L-shaped plate 43.

[0048] The discharge assembly 4 also includes a transmission pipe 46 connected to the side wall of the hydraulic telescopic rod 1 42, and the end of the transmission pipe 46 away from the hydraulic telescopic rod 1 42 is connected to the hydraulic telescopic rod 2 47, and the side wall of the hydraulic telescopic rod 2 47 is fixedly connected to the inner wall of the accommodating square tube 31. The above-mentioned special-shaped ring 1 38 controls the sliding of the sliding square tube 32 through the roller 36, and a discharge assembly 4 is provided inside the equipment. After the accommodating square tube 31 completes the discharge at the highest position, as the processing tube 12 rotates, the roller 36 is gradually reset under the push of the spring 1 37, and the rolling column 44 will enter the protruding position of the special-shaped ring 2 49 again, so that the rolling column 44 drives the hydraulic telescopic rod 1 42 to extend along the protruding position of the special-shaped ring 2 49 through the L-shaped plate 43. The extended hydraulic telescopic rod 1 42 will extract the liquid inside the hydraulic telescopic rod 2 47 through the transmission pipe 46, so that the hydraulic telescopic rod 2 47 is contracted. The contracted hydraulic telescopic rod 2 47 forces the rotating plate 48 to rotate, so that the rotating plate 48 is moved from Figure 7 The state F changes to the state G, and at this time the gap between the rotating plate 48 and the accommodating square tube 31 will force the sewage to fall downward through the gap and re-collect inside the sewage in the treatment pipe 12. At this time, the falling sewage will impact the sewage inside the treatment pipe 12, causing the sewage inside the treatment pipe 12 to carry more flocs and flow to the position G, thereby improving the collection efficiency of the equipment.

Taking advantage of the fact that the position of the above-mentioned accommodating square tube 31 changes with the change of the mounting groove 21, a collecting assembly 5 is provided inside the equipment. When the accommodating square tube 31 reaches the highest position to pour out the sewage, the sewage will be poured into the collecting box 52. At this time, the collecting box 52 will collect the sewage sprayed out, and as the position of the accommodating square tube 31 changes, the sewage inside the collecting box 52 will gradually tilt and pour downward, and finally enter the accommodating box 54, realizing the overall collection of the sewage; in addition, due to the change in the position of the collecting box 52, when the collecting box 52 reaches the lowest part, the counterweight slider 53 will slide downward along the inner wall of the collecting box 52, presenting a Figure 10 The counterweight slider 53 is in the H state, and during the downward movement, it will scrape the inner wall of the collection box 52 to remove the impurities remaining inside the collection box 52.

[0051] The use process of the wastewater treatment device for ink and coating production includes the following steps:

[0052] S1: Advance preparation: Workers can connect multiple devices end to end based on the floc content in the sewage to extend the processing time;

[0053] S2: Connecting the water pipe: Before use, install the base 1 in the desired position, and then ensure that the water inlet pipe 11 is connected to the external water pipe;

[0054] S3: Turn on the power: When the sewage containing flocs enters the treatment pipe 12 through the water inlet pipe 11, first ensure that the horizontal position of the sewage is not higher than the center point of the treatment pipe 12, and then turn on the power of the motor 22.

[0055] A specific application of this embodiment is: before use, the base 1 is installed in the desired position, and then, it is ensured that the water inlet pipe 11 is connected to the external water pipe, and the staff can connect multiple devices end to end according to the floc content contained in the sewage to extend the processing time; when the sewage containing flocs enters the treatment pipe 12 through the water inlet pipe 11, first ensure that the horizontal position of the sewage is not higher than the center point of the treatment pipe 12, and then turn on the power of the motor 22, and the motor 22 drives the gear ring 24 and the treatment pipe 12 to rotate clockwise through the driving gear 23, and the rotating treatment pipe 12 will drive the six accommodating square tubes 31 to rotate at the same time. When the accommodating square tube 31 is in Figure 9 When the position F is in the middle, the rolling column 44 is affected by the change of the outer wall of the special-shaped ring 49, causing the rotating plate 48 to rotate, showing as Figure 7 In the middle G state, the sewage inside the treatment pipe 12 passes through the gap between the rotating plate 48 and the accommodating square pipe 31 and enters the accommodating square pipe 31, the sliding square pipe 32 and the U-shaped slide plate 33; and as the treatment pipe 12 rotates, the accommodating square pipe 31 filled with sewage and flocs will reach the top of the treatment pipe 12. At this time, due to the pressure generated by the sewage flowing outward through the gap between the rotating plate 48 and the accommodating square pipe 31 and the deadweight of the rotating plate 48, the rotating plate 48 will completely block the accommodating square pipe 31, presenting as shown in the figure. Figure 7 In the state of middle F, the accommodating square tube 31, the sliding square tube 32, the U-shaped slide 33 and the fixed plate 34 will form a closed space, so that the internal sewage and flocs are in a relatively stable state. When the sliding square tube 32 reaches the top, the roller 36 will enter the gentle position of the special-shaped ring 1 38. At this time, the roller 36 will drive the sliding square tube 32 to slide downward along the inner wall of the accommodating square tube 31, so that a gap is formed between the U-shaped slide 33 and the sliding square tube 32, showing as follows Figure 6 In this state, the sliding square tube 32 moves downward, but the total amount of sewage inside remains unchanged. When the sliding square tube 32 moves downward, part of the sewage will carry flocs and be discharged outward through the gap between the U-shaped slide plate 33 and the sliding square tube 32. Through the application of the above components, while removing most of the flocs, the problem of filter screen clogging and the need for frequent replacement and cleaning can be avoided.

[0056] Utilizing the characteristic that the above-mentioned special-shaped ring 1 38 controls the sliding of the sliding square tube 32 through the roller 36, a discharge assembly 4 is provided inside the equipment, wherein, after the accommodating square tube 31 completes the discharge at the highest position, as the processing tube 12 rotates, the roller 36 is gradually reset under the push of the spring 1 37, and the rolling column 44 will enter the protruding position of the special-shaped ring 2 49 again, so that the rolling column 44 drives the hydraulic telescopic rod 1 42 to extend along the protruding position of the special-shaped ring 2 49 through the L-shaped plate 43, and the extended hydraulic telescopic rod 1 42 will extract the liquid inside the hydraulic telescopic rod 2 47 through the transmission pipe 46, so that the hydraulic telescopic rod 2 47 will contract, and the contracted hydraulic telescopic rod 2 47 forces the rotating plate 48 to rotate, so that the rotating plate 48 moves from Figure 7 The state F changes to the state G, and at this time the gap between the rotating plate 48 and the accommodating square tube 31 will force the sewage to fall downward through the gap and re-collect inside the sewage in the treatment pipe 12. At this time, the falling sewage will impact the sewage inside the treatment pipe 12, causing the sewage inside the treatment pipe 12 to carry more flocs and flow to the position G, thereby improving the collection efficiency of the equipment.

[0057] By utilizing the characteristics that the rotating plate 48 and the fixed plate 34 are extended by the influence of the special-shaped ring 1 38 and the special-shaped ring 2 49, as shown in FIG. Figure 9 When the accommodating square tube 31 reaches position F, the special-shaped ring 1 38 is open and the fixed plate 34 is in a closed state. When the accommodating square tube 31 reaches position A, the special-shaped ring 1 38 is completely closed, and a gap is formed between the fixed plate 34 and the sliding square tube 32. When the accommodating square tube 31 reaches position B, the gap between the fixed plate 34 and the sliding square tube 32 is not completely closed, and the special-shaped ring 1 38 is also in an open state, so that the sewage inside the accommodating square tube 31 is re-mixed with the sewage inside the treatment tube 12. When the other three positions are used, the special-shaped ring 1 38 and the fixed plate 34 are both in a closed state. Through the application of the above components, the orderliness of the equipment in treating sewage is guaranteed when it is in use.

[0058] Taking advantage of the fact that the position of the above-mentioned accommodating square tube 31 changes with the change of the installation groove 21, a collecting component 5 is provided inside the equipment. When the accommodating square tube 31 reaches the highest position and pours out the sewage, the sewage will be poured into the collection box 52. At this time, the collection box 52 will collect the sewage sprayed out, and as the position of the accommodating square tube 31 changes, the sewage inside the collection box 52 will gradually tilt and pour downward, and finally enter the interior of the accommodating box 54, realizing the overall collection of the sewage; in addition, due to the change in the position of the collection box 52, when the collection box 52 reaches the lowest part, the counterweight slider 53 will slide downward along the inner wall of the collection box 52, presenting the following Figure 10 The counterweight slider 53 is in the H state, and during the downward movement, it will scrape the inner wall of the collection box 52 to remove the impurities remaining inside the collection box 52.
