Description

Technical Field

[0001] This utility model relates to the technical field of tobacco production equipment, and in particular to a grinding wheel cleaning device for a tobacco cutting machine. Background Technology

[0002] In the tobacco production process, a shredder is needed to cut the processed tobacco leaves or stems into shreds of a certain width that meet the requirements of the tobacco processing technology. The shredder's grinding system uses a grinding wheel to grind the blades as a whole. Compared to the segmented grinding of a rotary cutter, this reduces chipping and improves the quality of the shredded material. After the grinding wheel has been grinding the blades for a period of time, dirt will accumulate on it. To keep the grinding wheel sharp, it needs to be cleaned regularly to ensure the grinding effect on the blades and keep them sharp. In theory, during this process, the cleaning water will wash the tobacco oil, dirt, and grinding powder from the surface of the grinding wheel into the grinding wheel cleaning chamber and drain it away through the drain outlet. However, in actual production, it was found that the grinding dust and soot removed during cleaning could not be discharged from the drain in time. Mixed with tobacco fragments or shreds, these easily entangled at the drain, forming large clumps of dirt. This buildup and blockage of the drain prevented the timely drainage of the grinding wheel cleaning water, causing it to overflow from the cleaning chamber into the tobacco cutting chamber, contaminating the tobacco and producing water-stained soot, leading to serious production quality accidents. To solve this problem, some equipment adopted solutions such as enlarging the drain outlet and drainage pipes. However, some dirt still adhered to the drain outlet each time, forming deposits. After prolonged use, dirt accumulation and blockage still occurred at the drain outlet, and the blockage problem could not be completely resolved. Utility Model Content

[0003] The purpose of this invention is to provide a grinding wheel cleaning device for a shredder, which can backwash the drain outlet, effectively prevent the drain outlet from becoming blocked, and ensure smooth drainage.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A grinding wheel cleaning device for a shredder is provided, comprising a cleaning chamber and a drainage mechanism. The grinding wheel is placed in the cleaning chamber, and a cleaning nozzle is provided in the cleaning chamber, the cleaning nozzle being positioned towards the grinding wheel. A drain outlet is provided at the bottom of the cleaning chamber.

[0006] The drainage mechanism includes a drainage pipe and a backflushing pipe. One end of the drainage pipe is connected to the drain outlet. The backflushing pipe includes a main pipe, a first pipe, and a second pipe. One end of the main pipe is provided with a jet nozzle connected to the drainage pipe. The other end of the main pipe is connected to the first pipe and the second pipe, respectively. The end of the first pipe away from the main pipe is connected to an external clean water supply device to output high-pressure water flow to the jet nozzle. The end of the second pipe away from the main pipe is connected to an external compressed air device to output high-pressure airflow to the jet nozzle. Both the high-pressure water flow and the high-pressure airflow flow along the drainage pipe toward the drain outlet.

[0007] In one embodiment, the drainage pipe includes a first drainage pipe, an anti-clogging bend, and a second drainage pipe connected in sequence away from the drain outlet. The first drainage pipe is connected to the drain outlet, and the backflushing pipe is connected to the first drainage pipe. The anti-clogging bend includes a first bend and a second bend connected to each other. The first bend is located on the side adjacent to the drain outlet, and the horizontal height of the second bend is higher than that of the first bend. The end of the second drainage pipe away from the anti-clogging bend is provided with an outlet.

[0008] In one embodiment, the second drain pipe is provided with a drain solenoid valve for controlling the opening and closing of the second drain pipe.

[0009] In one embodiment, the first pipe is provided with a first solenoid valve for controlling the opening and closing of the first pipe, and the second pipe is provided with a second solenoid valve for controlling the opening and closing of the second pipe.

[0010] In one embodiment, a flow sensor is provided on the drainage pipe, and the flow sensor is electrically or signal-connected to the first solenoid valve and the second solenoid valve, respectively.

[0011] In one embodiment, the cleaning nozzle includes a steam nozzle and a water-air nozzle. The steam nozzle is connected to an external steam output device to spray high-temperature steam toward the grinding wheel, and the water-air nozzle is connected to an external clean water and compressed air output device to spray clean water or compressed gas toward the grinding wheel.

[0012] In one embodiment, the drainage mechanism further includes a water collection tank, which includes a tank body and a cover plate, forming a water collection cavity between the tank body and the cover plate. The cover plate is disposed on the top of the tank body to seal the water collection cavity. The cover plate is provided with a water collection port, which includes a water receiving end disposed opposite the outlet of the drainage pipe and a water collecting end communicating with the water collection cavity. Wastewater discharged from the drainage port flows along the drainage pipe and flows out from the outlet to the water collection port.

[0013] In one embodiment, the water collection chamber is further provided with a sedimentation tank, the top of the sedimentation tank is provided with an overflow port, the overflow port is connected to the water collection end, the overflow port and the cover plate are spaced apart to form an overflow gap, the overflow port is connected to the water collection chamber through the overflow gap, and the side of the water collection tank adjacent to the cover plate is provided with a drain pipe connected to the water collection chamber.

[0014] In one embodiment, the bottom of the water collection tank is provided with a drain pipe, one end of the drain pipe away from the sedimentation tank extends into the water collection tank, and the drain pipe is provided with a drain valve for controlling the opening and closing of the drain pipe.

[0015] In one embodiment, the drain pipe includes a drain outlet communicating with the water collection chamber. The drain outlet is located at the bottom of the water collection tank. The bottom of the water collection tank is also provided with a drain ramp. The drain ramp gradually increases in horizontal height from one end adjacent to the drain outlet along the other end away from the drain outlet.

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a grinding wheel cleaning device for a shredder. It outputs high-pressure airflow and high-pressure water flow to the drain outlet via a backflushing pipe, flushing away dirt and grime. This effectively disperses accumulated dirt at the drain outlet, allowing it to fall into the drain pipe and be smoothly discharged, preventing dirt buildup and blockage. Specifically, the high-pressure water flow has high inertia, directly transmitting kinetic energy to impact blockages. For viscous, soft blockages such as grinding dust and soot, the impact and dissolving effect of the high-pressure water flow are highly effective, breaking down, diluting, and carrying away these blockages. The high-pressure airflow, through compression, generates an "air hammer" effect, forming shock waves that effectively loosen stubborn blockages (such as partially hardened grease). Furthermore, for lightweight and easily entangled blockages such as tobacco and fibers, the high-pressure airflow generates an oscillation and airlift effect. The airflow forms bubbles in the water, and the expansion and collapse of these bubbles create violent disturbances that "shake off" the entangled blockages, preventing them from accumulating at the drain outlet and causing blockages. This invention effectively removes various types of blockages by using a combination of two backflushing media, achieving high cleaning efficiency. Simultaneously, the use of two backflushing media provides double protection; if one medium (e.g., the air source) temporarily fails in actual operation, the other (the water source) can still work independently, maintaining basic anti-clogging functionality and improving system reliability.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figures 1 to 4As shown, a shredder grinding wheel cleaning device of this embodiment includes a body 100, a cleaning chamber 110 is provided inside the body 100, a grinding wheel 200 is placed inside the cleaning chamber 110, a cleaning nozzle 120 is provided inside the cleaning chamber 110, the cleaning nozzle 120 is arranged facing the grinding wheel 200, and a drain outlet 130 is provided at the bottom of the cleaning chamber 110. It also includes a drainage mechanism 300, which includes a drainage pipe 310 and a backflushing pipe 320. One end of the drainage pipe 310 is connected to the drain outlet 130. The backflushing pipe 320 includes a main pipe 321, a first pipe 322 and a second pipe 323. One end of the main pipe 321 is provided with a jet nozzle 324 connected to the drainage pipe 310. The other end of the main pipe 321 is connected to the first pipe 322 and the second pipe 323 respectively. The end of the first pipe 322 away from the main pipe 321 is connected to an external clean water supply device (not shown) to output high-pressure water flow to the jet nozzle 324. The end of the second pipe 323 away from the main pipe 321 is connected to an external compressed air device (not shown) to output high-pressure airflow to the jet nozzle 324. Both the high-pressure water flow and the high-pressure airflow flow along the drainage pipe 310 toward the drain outlet 130.

[0032] In this embodiment, the external clean water supply equipment and the external compressed air equipment are water pumps, air pumps and other equipment used in the prior art. Operators can select the corresponding equipment according to the actual operation situation, which will not be described in detail here.

[0033] In this embodiment, high-pressure airflow and high-pressure waterflow are output to drain outlet 130 through backflushing pipe 320 to flush away dirt at drain outlet 130. This effectively disperses the dirt accumulated at drain outlet 130, allowing it to fall into drain pipe 310 and be smoothly discharged through drain pipe 310, preventing dirt from accumulating at drain outlet 130 and causing blockage, thus effectively solving the problem of sewage discharge blockage. Specifically, the high-pressure waterflow has high inertia and can directly transfer kinetic energy to directly impact blockages. For viscous and soft blockages such as sharpening dust and soot, the impact force and dissolving effect of the high-pressure waterflow are very effective, effectively breaking up, diluting, and carrying away these blockages. As for the high-pressure airflow, by compressing it, a "hammer" effect can be generated, forming a shock wave, which has a good loosening effect on stubborn blockages (such as partially hardened grease). Furthermore, for lightweight and easily tangled blockages such as tobacco and fibers, the high-pressure airflow can generate an oscillation effect and an airlift effect. The airflow forms bubbles in the water, and the expansion and collapse of the bubbles will generate violent disturbances, "shaking away" the tangled blockages and preventing them from accumulating at the drain outlet 130 and causing blockages.

[0034] This embodiment utilizes a combination of two backflushing media to effectively remove various types of blockages, achieving high unblocking efficiency. Furthermore, the use of two backflushing media provides double protection; if one media (e.g., an air source) temporarily fails in actual operation, the other (water source) can still operate independently, maintaining basic anti-blocking functionality and improving system reliability. In practical operation, the pressure range of the high-pressure water flow is set to 4-6 MPa, and the pressure range of the high-pressure air flow can be set to 1.5-8 MPa or 15-30 MPa. Specific pressure settings are not limited in this embodiment and can be set according to the equipment and pipe specifications used in actual production. Sufficient water and air pressure should be selected while avoiding damage to equipment and pipes; such designs fall within the protection scope of this utility model.

[0035] In one embodiment, the drainage pipe 310 includes a first drainage pipe 311, an anti-clogging bend 312, and a second drainage pipe 313 connected sequentially along the drain outlet 130. The first drainage pipe 311 is connected to the drain outlet 130, and a backflushing pipe 320 is connected to the first drainage pipe 311. The anti-clogging bend 312 includes a first bend 3121 and a second bend 3122 connected to each other. The first bend 3121 is located on the side adjacent to the drain outlet 130, and the horizontal height of the second bend 3122 is higher than that of the first bend 3121. The end of the second drainage pipe 313 away from the anti-clogging bend 312 has an outlet 315. This design makes it difficult for dirt to accumulate at the anti-clogging bend 312 during drainage, because the special structure of the anti-clogging bend 312 causes a certain swirling effect when the water flows through, which helps to carry away the dirt smoothly.

[0036] Specifically, the design of the anti-clogging bend 312 creates a U-shaped loop in the vertical pipe. When water flows through it, it cannot flow directly as in a straight pipe, but must flow upwards and then downwards. After each use, some water will not be able to flow past the highest point of the second bend 3122. This water will remain permanently at the bottom of the first bend 3121, forming a "water seal". The water seal of the anti-clogging bend 312 can buffer the slight fluctuations in air pressure in the drainage pipe 310 to a certain extent, preventing the sediment deep in the drainage pipe 310 from being stirred up and pushed to the outlet due to sudden pressure changes, thus preventing blockage. At the same time, it can also prevent the backflow of odors.

[0037] Furthermore, such as Figure 4As shown, a cleaning port 3123 is provided at the first bend 3121, and sealed with a cap 3124. The cap 3124 can be opened periodically to clean the first bend 3121, preventing dirt accumulation and blockage. The cap 3124 can be connected to the cleaning port 3123 via a threaded connection, or a sealing ring (not shown) can be provided at the edge where the cap 3124 abuts against the cleaning port 3123. This ensures effective sealing of the cleaning port 3123 by the cap 3124 and facilitates easy installation and removal of the cap 3124. In practical applications, the bending angle and length of the anti-clogging bend 312 can be adjusted according to the specific usage environment and drainage requirements. S-shaped or N-shaped structures are commonly used to achieve optimal anti-clogging and drainage effects. Furthermore, the outlet 315 on the second drain pipe 313 can be configured in various forms, such as circular or square, to meet the interface requirements of different drainage systems.

[0038] In one embodiment, the second drain pipe 313 is equipped with a drain solenoid valve 3131 for controlling the opening and closing of the second drain pipe 313. The drain solenoid valve 3131 allows the operator to flexibly control the drainage status of the second drain pipe 313 according to actual needs. When drainage is required, the drain solenoid valve 3131 is opened, and sewage can be smoothly discharged through the second drain pipe 313. When drainage is not required or when the drain pipe 310 needs to be inspected or maintained, the drain solenoid valve 3131 is closed to prevent sewage from continuing to flow, providing convenience for subsequent operations. Furthermore, the drain solenoid valve 3131 can be electrically controlled and connected to the control system of the entire cleaning device to achieve automated control, further improving the convenience of operation and the intelligence level of the device.

[0039] In one embodiment, a first solenoid valve 3221 is provided on the first pipe 322 to control the opening and closing of the first pipe 322, and a second solenoid valve 3231 is provided on the second pipe 323 to control the opening and closing of the second pipe 323. The arrangement of the first solenoid valve 3221 and the second solenoid valve 3231 allows the operator to independently control the output of high-pressure water flow and high-pressure airflow. When the cleaning device starts working, one or both of the first solenoid valve 3221 and the second solenoid valve 3231 can be opened simultaneously, depending on the type and degree of blockage at the drain outlet 130. For example, for soft blockages such as grinding dust, the first solenoid valve 3221 can be opened first, using the impact force and dissolving effect of the high-pressure water flow to clean it. For stubborn blockages such as partially hardened grease, the second solenoid valve 3231 can be opened first, using the "air hammer" effect generated by the high-pressure airflow to loosen it. This flexible control method greatly improves the adaptability and blockage clearing efficiency of the cleaning device. Furthermore, the first solenoid valve 3221 and the second solenoid valve 3231 can also be electrically controlled and connected to the control system of the cleaning device to achieve automated operation, reduce manual intervention, and improve the overall intelligence level of the device.

[0040] In one embodiment, a flow sensor 314 is installed on the drainage pipe 310. The flow sensor 314 is electrically or signal-connected to the first solenoid valve 3221 and the second solenoid valve 3231, respectively. The flow sensor 314 can monitor the water flow in the drainage pipe 310 in real time. When an abnormal change in flow is detected, such as a significant decrease in flow, it is likely that a blockage has occurred at the drain outlet 130. At this time, the flow sensor 314 will quickly transmit a signal to the first solenoid valve 3221 and the second solenoid valve 3231. According to a preset program, if it is determined that the situation is suitable for water flow cleaning, the first solenoid valve 3221 will open in time, and the high-pressure water will be sprayed towards the drain outlet 130 through the backwash pipe 320 to impact and dissolve the blockage. If it is determined that airflow cleaning is required, the second solenoid valve 3231 will open, and the high-pressure airflow will generate an "air hammer" effect to treat the blockage. By linking the flow sensor 314 with the solenoid valve, the problem of blockage at the drain outlet 130 can be addressed more promptly and accurately, further improving the anti-blocking and unblocking capabilities of the cleaning device and ensuring that the entire shredder grinding wheel cleaning device can operate stably and efficiently.

[0041] In one embodiment, the cleaning nozzle 120 includes a steam nozzle 121 and a water-air nozzle 122. The steam nozzle 121 is connected to an external steam output device to spray high-temperature steam toward the grinding wheel 200, and the water-air nozzle 122 is connected to an external clean water and compressed air output device to spray clean water or compressed air toward the grinding wheel 200. Specifically, the high-temperature steam sprayed by the steam nozzle 121 can quickly soften stubborn dirt on the surface of the grinding wheel 200, especially for some oily or sticky impurities, which can be softened and removed by the high-temperature steam, facilitating subsequent cleaning. Furthermore, by softening the dirt on the surface of the grinding wheel 200 at high temperature, hard dirt can be further prevented from accumulating at the drain outlet 130 and causing blockage, thus improving the overall anti-clogging effect of the device.

[0042] In addition, during the cleaning process, after the dirt on the surface of the grinding wheel 200 is softened under high temperature steam, the dirt on the surface of the grinding wheel 200 can be cleaned by spraying clean water with the water nozzle 122. This can easily remove the dirt from the surface of the grinding wheel 200. Then, the water nozzle 122 can be switched to the blowing mode to blow away the remaining water on the surface of the grinding wheel 200, keeping the grinding wheel 200 dry and preventing the grinding wheel 200 from carrying moisture onto the blades and wetting the tobacco.

[0043] Furthermore, in other embodiments, the water-air nozzle 122 can flexibly switch between spraying clean water or compressed gas according to actual needs. When it is necessary to initially rinse the surface of the grinding wheel 200 to remove floating dust and impurities, clean water can be sprayed to wash away the dirt using the impact force of the water flow; while when it is necessary to perform deep cleaning of the grinding wheel 200 or clean some hard-to-reach corners, compressed gas can be sprayed to disperse the dirt using the blowing effect of the gas. This combination design of the steam nozzle 121 and the water-air nozzle 122 allows the cleaning nozzle 120 to adapt to different types and degrees of dirt cleaning needs, greatly improving the flexibility and cleaning effect of the cleaning device. At the same time, in actual operation, the setting of the steam nozzle 121 and the water-air nozzle 122 also increases the applicability of the cleaning device. Whether it is a newly installed grinding wheel 200 or an old grinding wheel 200 that has been used for a long time, the ideal cleaning effect can be achieved by adjusting the spray pattern and intensity of the nozzle.

[0044] In one embodiment, such as Figures 4 to 7As shown, the drainage mechanism 300 also includes a water collection tank 330, which includes a tank body 331 and a cover plate 332. A water collection cavity 333 is formed between the tank body 331 and the cover plate 332. The cover plate 332 is located on the top of the tank body 331 to seal the water collection cavity 333. The cover plate 332 is provided with a water collection port 3321. The water collection port 3321 includes a water receiving end provided with the water outlet 315 facing the drainage pipe 310 and a water collecting end communicating with the water collection cavity 333. The sewage discharged from the drain outlet 130 flows along the drainage pipe 310 and flows out from the water outlet 315 into the water collection port 3321. Specifically, the water inlet 3321 is positioned directly opposite the outlet 315. The water inlet 3321 is funnel-shaped, wider at the top and narrower at the bottom, with the opening of the inlet larger than the outlet 315. This allows for precise collection of wastewater flowing from the outlet 315 of the drainage pipe 310, preventing splashing and ensuring smooth flow into the collection chamber 333 for collection. The collection tank 330 effectively collects wastewater generated during the cleaning process, preventing it from flowing everywhere and polluting the surrounding environment. The cover 332 is equipped with a first handle 3322, allowing operators to easily open or close the cover 332 onto the top of the collection tank 330.

[0045] In one embodiment, a sedimentation tank 334 is also provided inside the water collection chamber 333. The top of the sedimentation tank 334 has an overflow outlet 3341, which communicates with the water collection end. An overflow gap 335 is formed between the overflow outlet 3341 and the cover plate 332, and the overflow outlet 3341 communicates with the water collection chamber 333 through the overflow gap 335. The sedimentation tank 334 allows wastewater to undergo preliminary sedimentation before entering the water collection chamber 333. Larger particles and dirt in the wastewater gradually settle to the bottom of the sedimentation tank 334, while relatively clear water flows into the water collection chamber 333 through the overflow outlet 3341 and the overflow gap 335. This not only reduces the impurity content of the wastewater in the water collection chamber 333, lowering the difficulty of subsequent treatment, but also effectively prevents sediment from clogging the water collection outlet 3321 and the drainage pipe 310.

[0046] In practical applications, the size and shape of the sedimentation tank 334 can be designed according to actual needs to ensure sufficient sedimentation space and good sedimentation effect. Simultaneously, the sedimentation tank 334 is detachably connected to the water collection tank 330. Specifically, the water collection tank 330 is equipped with a mounting bracket 339, on which the sedimentation tank 334 is placed or detachably mounted via screws or other fasteners. This allows operators to periodically remove and clean the sedimentation tank 334, discharging the settled dirt and ensuring the normal use of the sedimentation tank 334 and the stable operation of the water collection device. For example... Figure 7As shown, the sedimentation tank 334 is equipped with a second handle 3342, which allows the operator to hold the second handle 3342 to take out the sedimentation tank 334 or put it into the water collection tank 330.

[0047] Furthermore, the water collection tank 330 has a drain pipe 336 connected to the water collection chamber 333 on the side adjacent to the cover plate 332. When the sewage collected in the water collection chamber 333 reaches a certain amount, it can be discharged to a designated sewage treatment area for further treatment through the drain pipe 336. In addition, in actual operation, to facilitate observation of the sewage level in the water collection chamber 333, a level observation window (not shown) or a level sensor (not shown) can be installed on the water collection tank 330. The level observation window can be made of transparent material, allowing operators to directly view the sewage level in the water collection chamber 333. The level sensor can monitor the liquid level in the water collection chamber 333 in real time and transmit the signal to the control system of the cleaning device. When the liquid level reaches the set upper limit, the control system can issue an alarm to remind the operator to drain the sewage in time to prevent sewage overflow.

[0048] In one embodiment, such as Figure 5 and Figure 6 As shown, a drain pipe 337 is located at the bottom of the water collection tank 330. The end of the drain pipe 337 furthest from the sedimentation tank 334 extends into the water collection tank 330. A drain valve 3371 is installed on the drain pipe 337 to control its opening and closing. The drain valve 3371 allows operators to flexibly control the discharge of wastewater from the water collection tank 330 according to actual needs. When wastewater collected in the water collection chamber 333 needs to be discharged, the drain valve 3371 is opened, allowing the wastewater to be smoothly discharged through the drain pipe 337 to the designated wastewater treatment area for further purification. When drainage is not required or the water collection tank 330 is undergoing other operations, the drain valve 3371 is closed, effectively preventing further wastewater flow and preventing leakage that could pollute the environment. Furthermore, the drain valve 3371 can also be electrically controlled and connected to the control system of the entire cleaning device for automated operation. By setting a timed drainage program or based on feedback signals from a liquid level sensor, the control system can automatically control the opening and closing of the drain valve 3371, further improving operational convenience and the device's intelligence. Furthermore, the diameter and length of the drain pipe 337 can be customized according to actual drainage needs to ensure drainage efficiency meets usage requirements.

[0049] In one embodiment, such as Figure 6As shown, the drain pipe 337 includes a drain outlet 3372 connected to the water collection chamber 333. The drain outlet 3372 is located at the bottom of the water collection tank 330. A drain ramp 338 is also provided at the bottom of the water collection tank 330. The drain ramp 338 gradually increases in horizontal height from one end adjacent to the drain outlet 3372 to the other end away from the drain outlet 3372. This design allows sewage and sediment in the water collection tank 330 to naturally converge towards the drain outlet 3372 under the influence of gravity, facilitating the smooth discharge of sewage and the centralized cleaning of sediment. The drain ramp 338 not only improves sewage discharge efficiency but also reduces sewage residue at the bottom of the water collection tank 330, further ensuring the cleanliness of the water collection tank 330.
