Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, specifically to a device for recycling and reusing packaging material waste. Background Technology

[0002] Before packaging waste enters the crushing process, any residual liquid must be effectively treated to prevent liquid contamination of the crushing equipment, material adhesion, or bacterial growth, and to reduce the burden on subsequent cleaning processes. Methods such as tipping, centrifugal drying, or negative pressure suction are typically used to collect residual beverages, oil, chemical solvents, and other liquids from bottles, cans, boxes, and other packaging containers into a leak-proof storage tank, achieving solid-liquid separation.

[0003] In the prior art, patent CN115674501B discloses a composite processing technology and system for waste plastic bottles, including conveying and orienting the waste plastic bottles, stretching, feeding, and cutting the bottle body into strips, separating the plastic strips from the waste material through a screening device, and washing and drying the plastic strips. This type of solution can improve the recycling purity of waste plastic bottles to a certain extent and improve the problems of high sorting difficulty and complex cleaning process in traditional crushing and sorting. However, the aforementioned existing technologies mainly focus on the material separation, cutting, screening, and washing processes of waste plastic bottles. Their emphasis is on separating different material parts such as the bottle body, cap, and neck ring, without addressing the issue of residual waste liquid discharge before the packaging material waste enters the cutting, crushing, or washing processes. For packaging containers that are still in a closed, semi-closed, or basically intact state, if they are directly flattened, cut into strips, or crushed, the residual liquid inside the container often leaks out disorderly during the pressure or cutting process. The liquid easily adheres to the blades, rollers, conveyor belts, and the inner walls of the equipment, not only affecting the continuous operational stability of the equipment but also increasing the frequency of equipment cleaning and the pressure on subsequent wastewater treatment.

[0004] Meanwhile, existing methods such as tipping, centrifugal drying, or ordinary negative pressure suction are also difficult to apply to packaging containers that have not been pre-perforated. For packaging waste of different forms, such as plastic bottles, cardboard boxes, aluminum cans, or composite flexible packaging bags, if the container walls have not been broken, simple tipping or centrifugation is insufficient to fully drain the internal liquid; if the liquid is first squeezed and crushed to make it flow out, the crushing location is uncontrollable, and the waste liquid is prone to splashing everywhere or flowing along the gaps in the equipment, making it difficult to collect in a timely, centralized, and targeted manner, and still causing equipment pollution and environmental problems at the recycling site.

[0005] Furthermore, in existing processing equipment, puncture, conveying, suction, and drainage typically rely on separate mechanisms or external power units, resulting in insufficient structural coordination and low energy utilization. When packaging waste continuously enters the processing channel, if the suction action cannot be synchronized with the puncture and pressurized conveying, the waste liquid cannot be removed in a timely manner and may still be carried into the subsequent crushing process along with the packaging material. Therefore, existing technologies still need further improvement to achieve precise puncture, stable pressurized conveying, synchronous negative pressure suction, and centralized drainage of closed or semi-closed packaging containers before the packaging waste enters the crushing or deep processing stages. This would improve waste liquid pretreatment efficiency and reduce pollution to the crushing equipment and the subsequent cleaning burden.

[0006] In view of the above-mentioned problems, the present invention provides a device for recycling and reusing packaging material waste. Summary of the Invention

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 A packaging material waste recycling and reuse treatment device includes a longitudinally spaced piercing mechanism 1 and a pressure bearing mechanism 2; a piercing channel 7 is provided between the piercing mechanism 1 and the pressure bearing mechanism 2 for piercing the packaging material; a set of power mechanisms are connected to the same end of the piercing mechanism 1 and the pressure bearing mechanism 2, and the operation of the power mechanisms drives the piercing mechanism 1 and the pressure bearing mechanism 2 to rotate, piercing and pressing the packaging material passing through the piercing channel 7. The piercing mechanism 1 pierces the packaging material waste, and the pressure bearing mechanism 2 pressurizes and transfers the packaging material waste. At the same time, the waste liquid generated by the two is adsorbed and collected, realizing rapid and efficient waste liquid pretreatment. Moreover, the piercing treatment of packaging material waste is more conducive to subsequent rapid crushing and crushing. Specifically, the power mechanism includes a set of main servo motors 3, and the ends of the piercing mechanism 1 and the pressure bearing mechanism 2 are respectively connected to a transmission main shaft 8 and a transmission auxiliary shaft 9; both the transmission main shaft 8 and the transmission auxiliary shaft 9 are equipped with pulleys 4, and the two pulleys 4 are rotatably connected by a transmission belt 5. The end of the transmission main shaft 8 away from the piercing mechanism 1 is connected to the main servo motor 3 through a coupling, thereby realizing the transmission mode of driving the piercing mechanism 1 and the pressure bearing mechanism 2 to run synchronously through a single set of motors; Preferably, a support sleeve 6 is fitted on both the transmission main shaft 8 and the transmission auxiliary shaft 9 for limiting and fixing them. The position of the support sleeve 6 can be selected based on the actual application scenario. Details and selection will not be elaborated here.

[0026] It should be noted that the width and height of the puncture channel 7 can be set according to the type, size, and deformation of the packaging material waste to be treated. For example, when the object to be treated is a plastic bottle, aluminum can, cardboard box, or flexible packaging bag, the distance between the puncture mechanism 1 and the pressure bearing mechanism 2 can be adjusted to effectively contact and puncture the packaging material waste.

[0027] Furthermore, the puncture mechanism 1 includes a puncture unit and a waste liquid adsorption unit I; the puncture unit rotates to puncture and break the packaging material waste in the puncture channel 7, allowing the waste liquid inside to be discharged, and then the waste liquid adsorption unit I automatically adsorbs and collects the waste liquid; at the same time, the waste liquid adsorption unit I is connected to the power mechanism through a differential transmission assembly, that is, under the action of the differential transmission assembly, the kinetic energy of the waste liquid adsorption unit I comes from the rotational kinetic energy given to the puncture mechanism 1 by the power mechanism. While driving the puncture mechanism 1 to rotate, the power mechanism converts and utilizes part of the rotational kinetic energy to drive the waste liquid adsorption unit I to adsorb and collect the waste liquid; The pressure-bearing mechanism 2 includes a pressure-bearing unit and a waste liquid adsorption unit II. The pressure-bearing unit rotates to support and transfer the packaging material waste in the puncture channel 7. At the same time, some of the waste liquid generated by the puncture unit is transferred to the pressure-bearing unit, where it is automatically adsorbed and collected by the waste liquid adsorption unit II. The waste liquid adsorption unit II is also connected to the power mechanism through a differential transmission assembly. That is, while driving the pressure-bearing mechanism 2 to rotate, the power mechanism converts and utilizes some of the rotational kinetic energy to drive the waste liquid adsorption unit II to adsorb and collect the waste liquid.

[0028] In embodiments of the present invention, such as Figures 1-6 As shown, the puncture unit includes a puncture roller 100 connected to the drive shaft 8. One end of the puncture roller 100 facing the drive shaft 8 is coaxially fixedly connected to a drain rod 106. The drain rod 106 extends into the drive shaft 8. The drive shaft 8 has a hollow structure inside. A rotary joint drainer 120 is provided on the outside of the connection between the drive shaft 8 and the drain rod 106. Waste liquid is discharged through the rotary joint drainer 120. The inner end of the drain rod 106 extends into the puncture roller 100 and is connected to the waste liquid adsorption unit I. A support collar 10 is fitted on the outside of the other end of the puncture roller 100. The support collar 10 cooperates with the support rod 6 to control the stable rotation of the puncture roller 100. Specifically, a ring of puncture needle bases 101 is fixedly wrapped around the outer wall of the puncture roller 100. The puncture needle bases 101 are provided with multiple rings of puncture needle groups evenly arranged along the axial direction. Each ring of puncture needle groups consists of multiple puncture needles 102 distributed at equal intervals along the ring. That is, when the puncture needle groups rotate with the puncture roller 100, they squeeze and puncture the packaging material waste in the puncture channel 7 to create holes. The puncture needle 102 is designed with a conical structure to facilitate precise puncture of packaging material waste. Multiple suction grooves 103 are evenly spaced along the annular upper side of the root of the puncture needle 102. Multiple suction holes 104 are formed inside the suction grooves 103. The inner sides of the suction holes 104 are connected to a suction transfer tube 105. The inner end of the suction transfer tube 105 extends towards the inside of the puncture roller 100 and is connected to the waste liquid adsorption unit I via an inner suction tube 107. That is, through the puncture contact between the puncture needle 102 and the packaging material waste, and with the help of the suction holes 104, the waste liquid around the suction holes 104 is quickly adsorbed and transferred to the suction transfer tube 105 under the adsorption force of the waste liquid adsorption unit I, and then enters the waste liquid adsorption unit I through the inner suction tube 107.

[0029] Waste liquid adsorption unit I includes a main drain pipe 122 located in the middle of the piercing roller 100. Each suction inner tube 107 is connected to the main drain pipe 122 at its end. The main drain pipe 122 is provided with an inlet 116 at the position corresponding to the suction inner tube 107. An inwardly opening sealing plate 117 is elastically provided inside the inlet 116 and swings toward the inside of the main drain pipe 122. When the inwardly opening sealing plate 117 is in a free state, it seals the inlet 116. When it is subjected to an adsorption force toward the inside of the main drain pipe 122, it swings inward. At this time, the inlet 116 opens, and then an adsorption force is generated inside the suction inner tube 107. One end of the main drain pipe 122 is connected to the drain cylinder rod 106, and a drain port 118 is provided between the two. An outwardly opening sealing plate 119 is elastically provided on the inner side of the drain port 118 and swings toward the inside of the drain cylinder rod 106. When the outwardly opening sealing plate 119 is in a free state, it controls the drain port 118 to be sealed. When it is under pressure, it swings toward the inside of the drain cylinder rod 106. At this time, the outwardly opening sealing plate 119 opens and transfers the waste liquid in the main drain pipe 122 toward the drain cylinder rod 106. The other end of the main drain pipe 122 is rotatably connected to a pumping assembly. The driving end of the pumping assembly is connected to a differential transmission assembly. The differential transmission assembly follows the rotation of the piercing roller 100, thereby driving the pumping assembly to run. This cycle controls the change in air pressure inside the main drain pipe 122, thereby controlling the opening and closing of the inner opening sealing plate 117 and the outer opening sealing plate 119.

[0030] In one example of the present invention, such as Figure 1 , Figures 7-8As shown, the pressure-bearing unit includes a pressure-bearing roller 200. Both ends of the pressure-bearing roller 200 are connected to end cylinders 204. A drain cylinder rod 208 is provided at the center of the side of the end cylinder 204 facing the transmission auxiliary shaft 9. The outer end of the drain cylinder rod 208 extends into the interior of the transmission auxiliary shaft 9. The inner end of the drain cylinder rod 208 is connected to the waste liquid adsorption unit II. The interior of the transmission auxiliary shaft 9 is set as a cavity structure. A rotary joint type drainer 120 is provided on the outside of the connection between the transmission auxiliary shaft 9 and the drain cylinder rod 208. The liquid in the drain cylinder rod 208 is discharged to the outside through the rotary joint type drainer 120. The other end of the pressure-bearing roller 200 is also supported for rotation by a support collar 10. The outer circumferential wall of the pressure roller 200 contacts the packaging material waste in the puncture channel 7, supporting and transferring it. Simultaneously, an elastic pressure-bearing layer is provided on the outer circumferential wall of the pressure roller 200. This layer, covering the outer circumferential wall of the pressure roller 200, forms a buffer contact when supporting the packaging material waste under pressure, and improves the conveying stability of the packaging material waste in the puncture channel 7. The elastic pressure-bearing layer is preferably made of wear-resistant rubber, silicone, polyurethane elastomer, or nitrile rubber. The elastic pressure-bearing layer is fixed to the outer circumferential wall of the pressure roller 200 by vulcanization bonding, interference fit, screw plate fixing, or detachable clamps.

[0031] Waste liquid adsorption unit II includes a main discharge channel 205 located at the axis of the pressure roller 200. One end of the main discharge channel 205 is connected to the discharge cylinder rod 208, and the other end is also rotatably connected to a pump assembly. One side of the pump assembly is also connected to a differential transmission assembly. Multiple evenly distributed liquid absorption channels 201 are arranged in a ring on the outer wall of the pressure roller 200. The liquid absorption channels 201 are parallel to the axis of the pressure roller 200. Liquid absorption holes 203 are evenly opened inside the liquid absorption channels 201. Adjacent liquid absorption channels 201 are connected by connecting channels 202. The design of the liquid absorption channels 201 and connecting channels 202 facilitates the collection of waste liquid generated after puncturing packaging material waste, which is then absorbed through the liquid absorption holes 203. The inner side of the liquid absorption holes 203 in each liquid absorption channel 201 is connected to a transfer transmission pipe 207 set on the inner wall of the pressure roller 200. The transfer transmission pipe 207 is connected to the interior of the main drainage channel 205 through an auxiliary adsorption pipe 206, that is, each liquid absorption hole 203 is connected to the main drainage channel 205. The auxiliary adsorption tube 206 is connected to the main drainage channel 205 by an inlet 209. Inside the inlet 209 is an inner-opening sealing plate 210 that is elastic and swings towards the inside of the main drainage channel 205. When the inner-opening sealing plate 210 is in a free state, the inlet 209 is closed. When it is subjected to inward adsorption force, it opens, thereby transferring the waste liquid around the suction hole 203 to the main drainage channel 205. The main drainage channel 205 is connected to the drainage cylinder rod 208 by a drainage port 211. Inside the drainage port 211 is an outer-opening sealing plate 212 that is elastic and swings towards the inside of the drainage cylinder rod 208. When the outer-opening sealing plate 212 is in a free state, the drainage port 211 is closed. When the main drainage channel 205 is subjected to pressure, the drainage port 211 opens, thereby discharging the waste liquid in the main drainage channel 205 through the drainage cylinder rod 208.

[0032] Among them, the pump assembly and differential transmission assembly in waste liquid adsorption unit I and waste liquid adsorption unit II are the same as those in waste liquid adsorption unit I. This section describes the pump assembly and differential transmission assembly in Waste Liquid Adsorption Unit I; for example... Figure 1 , Figure 3 , Figure 6 As shown, specifically, the pump assembly includes a piston cylinder 108 connected to the end of the main drain pipe 122. A piston 109 is movably disposed inside the piston cylinder 108. An external fixing plate 131 is connected to the top side of the piston cylinder 108 via a fixing rod 110. The main drain pipe 122 and the piston cylinder 108 are connected via a rotary sealing joint. The rotating end of the rotary sealing joint is connected to the main drain pipe 122, and the fixed end is connected to the piston cylinder 108. A U-shaped connecting rod 115 is connected to the middle of one side of the piston 109 via a connecting rod. The opening side of the U-shaped connecting rod 115... A ball nut 114 is connected, and a ball screw 113 is threadedly connected to the middle of the ball nut 114. One end of the ball screw 113 is connected to the differential transmission assembly. The ball nut 114 is provided with a guide device to limit its rotation. Under the action of the differential transmission assembly, the ball screw 113 is driven to rotate, which in turn drives the ball nut 114 to move back and forth along the ball screw 113. Then, under the connection of the U-shaped connecting rod 115, the piston 109 is controlled to move back and forth inside the piston cylinder 108, thereby adjusting the pressure change inside the main drain pipe 122. Furthermore, the main drainage channel 205 is also connected to the corresponding piston cylinder 108 through a rotary sealing joint. The rotating end of the rotary sealing joint is connected to the main drainage channel 205, and the fixed end is connected to the corresponding piston cylinder 108. It should be noted that the inner diameters of the first drain cylinder rod 106 and the second drain cylinder rod 208 are not less than the inner diameters of the main drain pipe 122 and the main drain channel 205, in order to reduce the resistance to waste liquid discharge; the inner diameters of the suction inner tube 107 and the auxiliary adsorption tube 206 are smaller than the inner diameters of the main drain pipe 122 and the main drain channel 205, so as to increase the suction flow rate during the negative pressure stage.

[0033] The differential transmission assembly includes a gear ring 112 fixed to the inner wall of the puncture roller 100. A drive gear 124 is located at the center of the gear ring 112. One side of the drive gear 124 is connected to a ball screw 113 via a drive rod 111. The drive gear 124 and the gear ring 112 are meshed and connected via a transition gear 123. A positioning rod 125 is connected to the center of the other side of the drive gear 124. A limiting rotating block 126 is installed at the end of the positioning rod 125. One side of the limiting rotating block 126 is indirectly limited and rotatedly connected to an external fixing plate 131. A support rod 132 is connected to the outside of the external fixing plate 131. The bottom of the support rod 132 is supported by a bracket 133. The external fixing plate 131 and the puncture roller 100 are independently distributed, that is, the position of the puncture roller 100 corresponding to the position of the external fixing plate 131 is set as an opening. A connecting base rod 128 is installed at the position of rod 125. A limiting rotation hole 127 is provided in the connecting base rod 128 at the position corresponding to the limiting rotation block 126. The limiting rotation block 126 is placed in the limiting rotation hole 127 for limiting rotation. At the same time, a gear shaft 129 is connected to the side of the transition gear 123 facing the inner wall of the outer fixing plate 131. A rotation slot 130 is provided on the inner wall of the outer fixing plate 131 corresponding to the end of the gear shaft 129. When the transition gear 123 rotates, the gear shaft 129 rotates inside the rotation slot 130, thus maintaining the rotational stability of the transition gear 123. That is, the rotation of the piercing roller 100 drives the gear ring 112 to rotate, and then the meshing of the transition gear 123 drives the drive gear 124 to rotate, thereby driving the ball screw 113 to rotate, realizing the back-and-forth movement drive of the ball nut 114, thereby controlling the air pressure change in the piston cylinder 108. In a preferred embodiment of the present invention, the ball screw 113 is configured as a reciprocating ball screw, and the outer periphery of the ball screw 113 is provided with a reciprocating helical groove. The inner side of the ball nut 114 is provided with balls or guide pins that cooperate with the reciprocating helical groove, so that when the ball screw 113 rotates continuously in one direction, the ball nut 114 can automatically reciprocate along the axial direction of the ball screw 113. The two ends of the ball screw 113 are rotatably supported on the external fixed plate 131 or the connecting base rod 128 by deep groove ball bearings, angular contact bearings or needle roller bearings to ensure the stable rotation of the ball screw 113.

[0034] The guiding device includes a guide slider and a guide rail. The guide rail is fixed to the outside of the external fixing plate 131 or the piston cylinder 108 and is arranged parallel to the axis of the ball screw 113. The guide slider is fixedly connected to the ball nut 114 and slidably disposed within the guide rail. Alternatively, the guiding device includes a guide rod and a guide sleeve. The guide rod is fixed to the external fixing plate 131, and the guide sleeve is fixed to the ball nut 114 and slidably disposed outside the guide rod. The guide rail or guide rod is used to restrict the ball nut 114 from rotating synchronously with the ball screw 113, so that the ball nut 114 can only move along the axial direction of the ball screw 113. The guide rail is preferably a linear guide rail.

[0035] In a preferred embodiment of the present invention, the internal structures of the second suction hole 203 and the first suction hole 104 are configured with a one-way anti-clogging structure.

The elastic valve is located inside the filter screen and is preferably made of silicone, fluororubber, or polyurethane, with a thickness preferably between 0.2 mm and 1.0 mm. The elastic valve opens inward under negative pressure and automatically closes under reverse pressure or without negative pressure. The limiting ring is located inside the elastic valve and limits its maximum opening angle, preferably between 20° and 70°. The combination of the filter screen and the elastic valve prevents clogging of the first suction hole 104 and the second suction hole 203, and prevents backflow of waste liquid from the main drain pipe 122 or the main drain channel 205.

[0036] As a preferred embodiment of the present invention, an annular clearance is reserved between the external fixing plate 131 and the opening edge of the piercing roller 100, and an annular sealing ring or a labyrinth-type protective cover is provided at the opening to avoid interference between the piercing roller 100 and the external fixing plate 131 when the roller rotates, and to prevent waste liquid from entering the differential transmission assembly. The annular clearance is preferably 2mm-10mm, and more preferably 3mm-6mm. An annular sealing ring, a flexible liquid-retaining ring, or a labyrinth-type protective cover is provided at the opening. The annular sealing ring is preferably made of nitrile rubber or fluororubber, and the labyrinth-type protective cover is preferably made of stainless steel sheet or engineering plastic. This is used to prevent waste liquid and packaging debris from entering the differential transmission component, and at the same time to avoid interference between the piercing roller 100 and the external fixed plate 131 when the roller rotates.

[0037] As a preferred embodiment of the present invention, the rotary sealing joint is preferably a single-channel gas-liquid dual-purpose rotary joint, and its sealing element is preferably made of fluororubber, nitrile rubber or polytetrafluoroethylene.

[0038] The rotary joint type drainer 120 includes a fixed end, a rotating end, and a sealing assembly. The fixed end is connected to an external waste liquid collection pipeline, and the rotating end is connected to the main drive shaft 8 or the auxiliary drive shaft 9 respectively. Both the main drive shaft 8 and the auxiliary drive shaft 9 are hollow structures. The first drain cylinder rod 106 is connected to the inside of the main drive shaft 8, and the second drain cylinder rod 208 is connected to the inside of the auxiliary drive shaft 9. When the piercing roller 100 and the pressure roller 200 rotate, the waste liquid is discharged through the main drain pipe 122, the first drain cylinder rod 106, the main drive shaft 8, and the rotary joint type drainer 120, or through the main drain channel 205, the second drain cylinder rod 208, the auxiliary drive shaft 9, and the rotary joint type drainer 120. The fixed end of the rotary joint type drainer 120 is connected to a waste liquid collection tank, a seepage-proof storage tank, or a filter sedimentation tank via a hose; Furthermore, the rotary joint drainer 120 is located on the side of the transmission main shaft 8 near the puncture roller 100, or it is connected to the inside of the transmission main shaft 8 through a radial drain port opened on the side wall of the transmission main shaft 8, and the rotary joint drainer 120 is arranged in a staggered manner with the main servo motor 3 and the coupling.

[0039] In a preferred embodiment of the present invention, the power of the main servo motor 3 is preferably 0.75kW-3kW, and the output speed is preferably controlled at 20r / min-120r / min after deceleration; The transmission main shaft 8 and the transmission auxiliary shaft 9 are preferably connected by a cross transmission belt, a synchronous belt, a reversing wheel, or a gear reversing assembly, so that the piercing roller 100 and the pressure roller 200 form a feeding motion in the same direction at the piercing channel 7, thereby avoiding reverse pulling or jamming of packaging material waste in the piercing channel 7.

[0040] The pulley 4 is preferably a synchronous pulley, and the transmission belt 5 is preferably a polyurethane synchronous belt, a rubber synchronous belt, or an oil-resistant V-belt.

[0041] The working principle of this invention is as follows: Step 1, the main servo motor 3 starts and drives the transmission main shaft 8 to rotate. The transmission main shaft 8 drives the piercing roller 100 to rotate. At the same time, the transmission main shaft 8 drives the transmission auxiliary shaft 9 to rotate through the pulley 4 and the transmission belt 5. The transmission auxiliary shaft 9 drives the pressure roller 200 to rotate, so that the piercing roller 100 and the pressure roller 200 form a feeding motion at the piercing channel 7. Step 2: After the packaging material waste enters the puncture channel 7, the puncture needle 102 on the puncture needle base 101 rotates with the puncture roller 100 and squeezes and punctures the packaging material waste. The pressure roller 200 supports and transfers the packaging material waste through the elastic pressure layer on its circumferential outer wall. Step 3: The waste liquid inside the packaging material waste flows out through the hole. Part of the waste liquid enters the main drain pipe 122 through the first suction hole 104, the suction transfer pipe 105 and the inner suction pipe 107 in the suction hole groove 103. The other part of the waste liquid enters the main drain channel 205 through the suction channel groove 201, the second suction hole 203, the transfer transfer pipe 207 and the auxiliary adsorption pipe 206 on the outer wall of the pressure roller 200. Step 4: When the piercing roller 100 or the pressure roller 200 rotates, the gear ring 112 rotates synchronously and drives the drive gear 124 to rotate through the transition gear 123. The drive gear 124 drives the ball screw 113 to rotate through the drive rod 111. The ball nut 114 moves back and forth along the axial direction of the ball screw 113 under the restriction of the guide device, and drives the piston 109 to move back and forth in the piston cylinder 108 through the U-shaped connecting rod 115. Step 5: When piston 109 creates negative pressure in main drain pipe 122 and main drain channel 205, inner-opening sealing plate 117 and inner-opening sealing plate 210 open, and waste liquid is drawn into main drain pipe 122 and main drain channel 205. When piston 109 creates positive pressure in main drain pipe 122 and main drain channel 205, outer-opening sealing plate 119 and outer-opening sealing plate 212 open, and waste liquid is discharged through drain cylinder rod 106, drive shaft 8 and rotary joint drain 120, or through drain cylinder rod 208, drive auxiliary shaft 9 and rotary joint drain 120, and finally enters the external waste liquid collection pipeline.
