Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, and more specifically, to a solid-liquid separation device. Background Technology

[0002] Solid-liquid separation units, as key equipment in chemical production processes, play a vital role in improving production efficiency, product quality, and environmental protection. Particularly in the production of lithium carbonate, solid-liquid separation units are the core component ensuring the efficient extraction, separation, and purification of lithium carbonate from brine. They are irreplaceable in promoting the development of the lithium battery industry and meeting the demand for high-quality lithium carbonate in new energy vehicles and energy storage.

[0003] Traditional solid-liquid separation devices mainly include filtration, sedimentation, and centrifugal types, which are widely used in the solid-liquid separation of lithium carbonate. However, in traditional centrifugal solid-liquid separation devices, especially centrifugal separators, lithium carbonate solid particles tend to adhere to the inner wall of the separation tank when processing lithium carbonate solid-liquid mixtures. This can lead to clogging of filter holes or separation gaps, severely affecting the fluidity of the liquid and separation efficiency. Therefore, a cleaning component is needed to clean the inner wall. However, existing cleaning components cannot fit tightly against the inner wall of the separation tank. Especially after long-term cleaning, when components such as brushes wear down, the cleaning device cannot effectively clean the inner wall, resulting in poor cleaning effect, increased probability of clogging, and reduced separation efficiency. Utility Model Content

[0004] The main objective of this invention is to provide a solid-liquid separation device that can solve the problem that in existing solid-liquid separation devices, after prolonged cleaning, the cleaning components such as brushes wear down, making it impossible to effectively clean the inner wall, resulting in poor cleaning effect, increased probability of clogging, and reduced separation efficiency.

[0005] To achieve the above objectives, according to one aspect of the present invention, a solid-liquid separation device is provided, comprising a housing, a separation chamber, and a cleaning assembly. The separation chamber is rotatably disposed within the housing, and the cleaning assembly is disposed within the separation chamber. The cleaning assembly includes a cleaning brush and a pushing assembly, the pushing assembly being capable of adjusting the distance between the cleaning brush and the separation chamber.

[0006] Furthermore, the solid-liquid separation device also includes a connecting part, which is located inside the top plate of the housing and extends into the separation chamber. The cleaning component is located on the part of the connecting part that extends into the separation chamber.

[0007] Furthermore, the solid-liquid separation device also includes a fixing rod, with the first end of the fixing rod disposed on the connecting part and the second end of the fixing rod extending towards the bottom of the separation tank, and the cleaning component disposed on the fixing rod.

[0008] Furthermore, the solid-liquid separation device also includes a support section, which is located at the bottom of the separation tank, and the second end of the fixing rod is connected to the support section.

[0009] Furthermore, the cleaning assembly includes a fixing part and a mounting bracket. The fixing part is mounted on a fixing rod, and the mounting bracket is mounted on the fixing part and extends radially outward along the separation box. The cleaning brush and the pushing assembly are both mounted on the mounting bracket, and the pushing assembly is driven to connect with the cleaning brush.

[0010] Furthermore, multiple cleaning components are arranged in a circular array with the fixed rod at intervals.

[0011] Furthermore, the mounting bracket is provided with a mounting groove, and a first guide member is provided in the mounting groove. The pushing component includes a moving block and an elastic member. The moving block is provided at the end of the cleaning brush, and a mounting hole is provided on the moving block. The mounting hole is fitted onto the first guide member, and the elastic member is fitted onto the first guide member and is provided on the side of the moving block facing the fixed part.

[0012] Furthermore, the pushing component also includes a connecting plate and a second guide member. The connecting plate is connected to the mounting brackets at both ends of the fixing part. The connecting plate is provided with a guide hole, and the second guide member passes through the guide hole. One end of the second guide member is set on the cleaning brush.

[0013] Furthermore, the solid-liquid separation device also includes a first drive unit, which is mounted on the housing and is drivenly connected to the separation tank.

[0014] Furthermore, the first drive unit is installed on the top plate of the housing, and the first output shaft of the first drive unit extends into the housing through the top plate. A drive gear is provided at one end of the first output shaft that extends into the housing. A driven gear ring is sleeved on the outer periphery of the separation box, and the drive gear is drivenly connected to the driven gear ring.

[0015] Furthermore, the solid-liquid separation device also includes a discharge assembly, which is installed on the bottom plate of the box. The discharge assembly includes a discharge pipe, which is connected to the separation box through a connecting pipe. The discharge pipe passes through the side wall of the box, and a second discharge port is provided at the end of the discharge pipe that extends out of the box.

[0016] Furthermore, the discharge assembly also includes a second drive unit and a discharge unit. The second drive unit is disposed on the discharge pipe, and the discharge unit is disposed inside the discharge pipe and is drivenly connected to the second drive unit.

[0017] Furthermore, the second output shaft of the second drive unit passes through the end of the discharge pipe and extends along the axial direction of the discharge pipe. The discharge unit includes auger blades, which are fixedly connected to the second output shaft. The auger blades push the material toward the second discharge port.

[0018] The main function of the housing in this invention is to provide a closed working environment, housing the solid-liquid separation components such as the separation tank and cleaning assembly, while simultaneously collecting the separated liquid. The separation tank is used to achieve solid-liquid separation. When the separation tank rotates, water in the material is flung out through the filter holes on the side wall of the separation tank, while the material is blocked, thus achieving solid-liquid separation. The cleaning assembly is mainly used inside the separation tank to clean residual material on the inner wall, preventing these particles from clogging the separation holes or corroding the tank. The cleaning brush can directly contact the inner wall of the separation tank or maintain a sufficiently small gap to sweep away residual or adhered material, achieving a cleaning effect. The pushing assembly adjusts the distance between the cleaning brush and the separation tank, ensuring that the cleaning brush can always clean the inner wall of the separation tank. Even if the cleaning brush wears down after prolonged use, the pushing assembly can adjust the position of the cleaning brush, moving it closer to the inner wall until it reaches a position where it can continue cleaning the inner wall of the separation tank, thus ensuring the cleaning effect. By setting up a push component, the cleaning brush can always be in a position to sweep and clean the inner wall of the separation box. Even after the brush bristles wear down due to long-term cleaning, the push component can still keep the cleaning brush in the cleaning position, thereby ensuring the cleaning effect and avoiding problems such as clogging and reduced separation efficiency.

[0029] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] See also Figures 1 to 7 As shown, this utility model provides a solid-liquid separation device, which includes a housing 1, a separation box 3, and a cleaning component 4. The separation box 3 is rotatably disposed inside the housing 1, and the cleaning component 4 is disposed inside the separation box 3. The cleaning component 4 includes a cleaning brush 41 and a pushing component, which can adjust the distance between the cleaning brush 41 and the separation box 3.

[0031] In the above technical solution, the main function of the housing 1 is to provide a closed working environment to house the solid-liquid separation components, such as the separation tank 3 and the cleaning assembly 4, while collecting the separated liquid. The separation tank 3 is used to achieve solid-liquid separation. When the separation tank 3 rotates, water in the material is thrown out through the filter holes on the side wall of the separation tank 3, while the material is blocked, thereby achieving the effect of solid-liquid separation. The cleaning assembly 4 is mainly used inside the separation tank 3 to clean the material remaining on the inner wall of the separation tank 3, preventing these particles from clogging the separation holes or corroding the housing. Among them, the cleaning brush 41 can directly contact the inner wall of the separation tank 3 or maintain a sufficiently small gap with the inner wall, thereby sweeping off the material remaining or adhering to the inner wall, achieving the cleaning effect. The function of the pushing component is to adjust the distance between the cleaning brush 41 and the separation box 3, ensuring that the cleaning brush 41 can always clean the inner wall of the separation box 3. Even if the cleaning brush 41 wears down after prolonged use, the pushing component can adjust the position of the cleaning brush 41, moving it closer to the inner wall until it reaches a position where it can continue cleaning the inner wall of the separation box 3, thus ensuring cleaning effectiveness. By setting up the pushing component, the cleaning brush 41 can always be in a position where it can sweep and clean the inner wall of the separation box 3. Even after the bristles of the cleaning brush 41 wear down due to prolonged cleaning, the pushing component can still push the cleaning brush 41 to remain in the cleaning position, thus ensuring cleaning effectiveness and avoiding problems such as clogging and reduced separation efficiency.

[0032] In one embodiment of the present invention, the solid-liquid separation device further includes a connecting part 5, which is disposed inside the top plate 11 of the housing 1. The connecting part 5 extends into the separation box 3, and the cleaning component 4 is disposed on the part of the connecting part 5 that extends into the separation box 3.

[0033] In the above technical solution, the main function of the connecting part 5 is to provide a base for the cleaning component 4 to be installed and fixed, connecting the cleaning component 4 to the top plate 11 of the housing 1, and ensuring that the cleaning component 4 can extend into the separation box 3 so that the cleaning component 4 is in a position that can effectively clean the inner wall of the separation box 3. The cleaning component 4 is set on the part of the connecting part 5 that extends into the separation box 3, and its main function is to clean the solid particles attached to the inner wall of the separation box 3 during the operation of the separation box 3 or during the working interval, so as to prevent these particles from clogging the separation holes or corroding the material of the separation box 3.

[0034] In one embodiment of the present invention, the solid-liquid separation device further includes a fixing rod 44, the first end of which is disposed on the connecting part 5, the second end of which extends toward the bottom of the separation box 3, and the cleaning component 4 is disposed on the fixing rod 44.

[0035] In the above technical solution, the fixing rod 44 provides a base for supporting and fixing the cleaning component 4. The second end of the fixing rod 44 extends towards the bottom of the separation box 3, ensuring that the cleaning brush 41 can penetrate to a sufficient depth in the separation box 3 along the axial direction of the fixing rod 44, thereby covering the inner wall of the separation box 3 as comprehensively as possible and improving the cleaning effect on the inner wall of the separation box 3. The main function of the connecting part 5 is to allow the fixing rod 44 to be indirectly fixed to the box 1 through the connecting part 5, providing a reliable installation base for the fixing rod 44. At the same time, it allows the fixing rod 44 to move or be fixed independently of the separation box 3, avoiding the problem that the separation box 3 drives the fixing rod 44 to rotate at the same frequency, causing the cleaning component 4 on the fixing rod 44 to be unable to effectively clean the separation box 3.

[0036] In one embodiment of the present invention, the solid-liquid separation device further includes a support part 6, which is disposed at the bottom of the separation box 3, and the second end of the fixing rod 44 is connected to the support part 6.

[0037] In the above technical solution, the support part 6 is used to provide additional support for the fixed rod 44 and the cleaning component 4 on it, reducing the possibility of the cleaning component 4 falling or deviating from the cleaning position, thereby improving the stability and reliability of the cleaning component 4.

[0038] In one embodiment of the present invention, the cleaning component 4 includes a fixing part 42 and a mounting bracket 43. The fixing part 42 is disposed on the fixing rod 44, and the mounting bracket 43 is disposed on the fixing part 42 and extends outward along the radial direction of the separation box 3. The cleaning brush 41 and the pushing component are both disposed on the mounting bracket 43, and the pushing component is drivenly connected to the cleaning brush 41.

[0039] In the above technical solution, the fixing part 42 is directly mounted on the fixing rod 44. Its function is to provide a stable mounting point for the mounting bracket 43, ensuring the fixation and reliability of the entire cleaning assembly 4 inside the separation box 3. The mounting bracket 43 is mounted on the fixing part 42 and extends radially outward along the separation box 3. Its main function is to support the cleaning brush 41 and the pushing assembly, while ensuring that they can effectively contact the inner wall of the separation box 3. The cleaning brush 41 is mainly used to directly clean and remove solid particles or residues attached to the inner wall of the separation box 3. The pushing assembly is driven and connected to the cleaning brush 41. Its main function is to push the cleaning brush 41 toward the inner wall of the separation box 3 by mechanical force, ensuring that the cleaning brush 41 can still remain in the cleaning position even after the bristles wear down due to long-term cleaning, thereby ensuring the cleaning effect and avoiding problems such as clogging and reduced separation efficiency.

[0040] In one embodiment of this utility model, multiple cleaning components 4 are arranged in a circular array with the fixed rod 44 as the center.

[0041] In the above technical solution, arranging multiple cleaning components 4 in a circumferential array ensures that the inner wall surface of the separation box 3 can be thoroughly cleaned by the cleaning brush 41, improving cleaning efficiency and effectiveness. The spacing between the cleaning components 4 ensures that each component operates independently without interference, allowing them to perform cleaning tasks effectively. This design also provides sufficient space for the replacement and maintenance of the cleaning brush 41; even if some cleaning components 4 malfunction, others can still function normally, further reducing the risk of blockage in the separation box 3 and improving the reliability of the cleaning components 4.

[0042] In one embodiment of this utility model, the mounting bracket 43 is provided with a mounting groove 45, and a first guide member 46 is provided in the mounting groove 45. The pushing component includes a moving block 471 and an elastic member 472. The moving block 471 is provided at the end of the cleaning brush 41, and a mounting hole is provided on the moving block 471. The mounting hole is fitted onto the first guide member 46, and the elastic member 472 is fitted onto the first guide member 46 and is provided on the side of the moving block 471 facing the fixed part 42.

[0043] In the above technical solution, the mounting groove 45 is disposed on the mounting bracket 43 to accommodate and fix the first guide member 46. The first guide member 46 is a guide structure for the movement of the moving block 471 and the cleaning brush 41, guiding and limiting the moving block 471 to ensure that the cleaning brush 41 can only move radially along the separation box 3. The moving block 471 is located at the end of the cleaning brush 41 and is fitted onto the first guide member 46 through the mounting hole on the moving block 471, allowing the moving block 471 to slide along the first guide member 46, thereby driving the cleaning brush 41 to move. The cooperation between the moving block 471 and the elastic member 472 realizes the automatic adjustment of the distance between the cleaning brush 41 and the inner wall of the separation box 3, ensuring the continuity and stability of the contact between the cleaning brush 41 and the inner wall of the separation box 3. When the cleaning brush 41 contacts the inner wall of the separation box 3, the elastic member 472 applies a thrust towards the inner wall to the cleaning brush 41, so that the cleaning brush 41 can apply a certain pressure on the inner wall, thereby performing effective cleaning. As the cleaning brush 41 wears down, the elastic element 472 can push the cleaning brush 41 to move towards the inner wall of the separation box 3, thereby achieving the effect of automatically compensating for changes in the length of the cleaning brush 41, and thus keeping the cleaning brush 41 in the cleaning position to ensure cleaning effect and efficiency.

[0044] In one embodiment of the present invention, the pushing component further includes a connecting plate 473 and a second guide member 474. The connecting plate 473 is connected to the mounting brackets 43 at both ends of the fixing part 42. The connecting plate 473 is provided with a guide hole, and the second guide member 474 passes through the guide hole. One end of the second guide member 474 is disposed on the cleaning brush 41.

[0045] In the above technical solution, the main function of the connecting plate 473 is to connect the mounting brackets 43 at both ends of the fixing part 42 to form a more stable overall structure, while providing a foundation for the installation and guidance of the second guide member 474. The connecting plate 473 is provided with guide holes, which provide a guiding path for the second guide member 474. The cooperation between the second guide member 474 and the guide holes ensures more accurate movement of the cleaning brush 41, while reducing the probability of the cleaning brush 41 becoming misaligned or stuck due to asynchronous pushing of the elastic members 472 at both ends of the cleaning brush 41.

[0046] In one embodiment of the present invention, the solid-liquid separation device further includes a first driving unit 7, which is disposed on the housing 1 and is drivenly connected to the separation tank 3.

[0047] In the above technical solution, the first drive unit 7 is typically a power source such as an electric motor or hydraulic motor, and its main function is to provide power for the rotation of the separation box 3. The first drive unit 7 can directly or indirectly transmit power to the separation box 3, causing the separation box 3 to rotate at high speed and generate a strong centrifugal force, which throws the water-containing material in the separation box 3 onto the inner wall of the separation box 3. The filter holes on the side wall of the separation box 3 can block the material, while allowing the liquid to be discharged from the separation box 3 through the filter holes, thereby achieving the effect of solid-liquid separation.

[0048] In one embodiment of the present invention, the first drive unit 7 is disposed on the top plate 11 of the housing 1, the first output shaft 71 of the first drive unit 7 passes through the top plate 11 and extends into the housing 1, and a drive gear 72 is disposed at one end of the first output shaft 71 extending into the housing 1, and a driven gear ring 73 is sleeved on the outer periphery of the separation box 3, and the drive gear 72 and the driven gear ring 73 are drivenly connected.

[0049] In the above technical solution, the first drive unit 7 provides power for the rotation of the separation box 3. The first output shaft 71 is the transmission shaft between the first drive unit 7 and the drive gear 72, directly transmitting the power output by the motor to the drive gear 72. The drive gear 72 is fixed to one end of the first output shaft 71 that extends into the box body 1, and its main function is to mesh with the driven gear ring 73 on the separation box 3, transmitting power to the separation box 3. The driven gear ring 73 is sleeved on the outer periphery of the separation box 3, drivingly connected to the drive gear 72, and receiving the power transmitted from the drive gear 72. Through gear transmission, smooth power transmission can be achieved, and the rotation speed of the separation box 3 can be adjusted as needed to adapt to different solid-liquid separation requirements.

[0050] In one embodiment of the present invention, the solid-liquid separation device further includes a discharge assembly 9, which is disposed on the bottom plate 13 of the housing 1. The discharge assembly 9 includes a discharge pipe 93, which is connected to the separation box 3 through a connecting pipe 94. The discharge pipe 93 passes through the side wall 12 of the housing 1, and a second discharge port 97 is provided at one end of the discharge pipe 93 extending out of the housing 1.

[0051] In the above technical solution, the main function of the discharge pipe 93 is to collect and transport the solid material separated from the separation box 3. The connecting pipe 94 is the connecting bridge between the discharge pipe 93 and the separation box 3. One end of the connecting pipe 94 is connected to the first discharge port 31, and the other end is connected to the discharge pipe 93. The solid material separated from the separation box 3 is guided to the discharge pipe 93 through the connecting pipe 94. The second discharge port 97 is located at the end of the discharge pipe 93 that extends out of the box 1, ensuring that the solid material can be transported outside the solid-liquid separation device.

[0052] In one embodiment of the present invention, the discharge assembly 9 further includes a second driving part 91 and a discharge part 92. The second driving part 91 is disposed on the discharge pipe 93, and the discharge part 92 is disposed inside the discharge pipe 93 and is drivenly connected to the second driving part 91.

[0053] In the above technical solution, the second drive unit 91 is typically a drive motor, used to drive the discharge unit 92 to move, thereby achieving the effect of discharging solid material from the discharge pipe 93. The discharge unit 92 is typically a screw conveyor or other form of conveying mechanism. The discharge unit 92 is located inside the discharge pipe 93, and the second drive unit 91 drives the discharge unit 92 to rotate or move within the discharge pipe 93, thereby propelling the separated lithium carbonate solid particles forward and causing the material to be quickly discharged from the discharge pipe 93.

[0054] In one embodiment of the present invention, the second output shaft 95 of the second drive unit 91 passes through the end of the discharge pipe 93 and extends along the axial direction of the discharge pipe 93. The discharge unit 92 includes auger blades, which are fixedly connected to the second output shaft 95. The auger blades push the material toward the second discharge port 97.

[0055] In the above technical solution, the discharge section 92 includes auger blades, which are spiral-shaped conveying devices that can push solid materials from the second inlet 96 of the discharge pipe 93 to the second outlet 97. When the auger blades rotate, they gradually advance the separated solid particles forward through the spiral structure until they reach the second outlet 97 of the discharge pipe 93, thereby achieving continuous and stable discharge of solid particles.

[0056] In one embodiment of the present invention, the solid-liquid separation device further includes a drain pipe 8, which passes through the lower part of the side wall 12 of the housing 1 and is connected to the housing 1.

[0057] In the above technical solution, the main function of the drain pipe 8 is to discharge the waste liquid generated during the solid-liquid separation process. Since liquid or waste liquid usually accumulates at the bottom of the tank 1 under the action of gravity, placing the drain pipe 8 at the bottom can reduce the liquid residue in the tank 1 and improve the discharge efficiency.

[0058] In one embodiment of the present invention, the solid-liquid separation device further includes a slide rail 15, which is disposed on the inner side of the top plate. The top edge of the separation box 3 matches the slide groove in the slide rail 15, so that the top of the separation box 3 is slidably disposed in the slide rail 15.

[0059] In the above technical solution, the slide rail 15 is mainly used to provide guidance and support for the separation box 3, to ensure the stable operation of the separation box 3 during the rotation separation process, to reduce the vibration and noise generated during the rotation of the separation box 3, thereby improving the stability and reliability of the rotation of the separation box 3.

[0060] In one embodiment of this utility model, a first feed inlet 14 is provided at the center of the top plate 11. The first feed inlet 14 is the main channel for materials to enter the separation box 3. It is designed to be located at the center of the top plate 11, which can ensure that the materials can fall directly into the center of the separation box 3 when they enter. As a result, when the separation box 3 rotates and separates, the materials are more evenly distributed, which is conducive to improving the effect of centrifugal force, accelerating the solid-liquid separation speed, reducing separation time, and improving production efficiency.

[0061] In one embodiment of this utility model, the connecting part 5 is fixedly connected to the top plate 11, one end of the fixing rod 44 is fixedly connected to the connecting part 5, and the other end is fixedly connected to the support part 6, with the support part 6 suspended above the bottom plate 13.

[0062] In the above technical solution, the connecting part 5 and the supporting part 6 support and fix the fixing rod 44 and the cleaning component 4 on it. At this time, the cleaning component 4 is stationary while the separation box 3 rotates, so that the cleaning brush 41 on the cleaning component 4 can generate relative movement with the inner wall of the separation box 3 during the rotation of the separation box 3, thereby cleaning the inner wall of the separation box 3, avoiding the adhesion of lithium carbonate solid particles to the inner wall of the separation box 3, effectively preventing pore blockage and corrosion, ensuring the solid-liquid separation effect of the equipment, and improving the service life.

[0063] In one embodiment of the present invention, the connecting part 5 is fixedly connected to the top plate 11, and a driving device is provided on the connecting part 5. The driving device is drivenly connected to the fixing rod 44. One end of the fixing rod 44 is rotatably connected to the connecting part 5, and the other end is fixedly connected to the support part 6. The support part 6 is suspended above the bottom plate 13.

[0064] In the above technical solution, the driving device is used to drive the fixed rod 44 to rotate relative to the separation box 3 in the same direction but with different angular velocities, or in opposite directions. The connecting part 5 and the supporting part 6 support the fixed rod 44 and the cleaning assembly 4 on it. One end of the fixed rod 44 is rotatably connected to the connecting part 5, ensuring that the fixed rod 44 and the cleaning assembly 4 on it can rotate relative to the connecting part 5. The rotation of the fixed rod 44 and the cleaning assembly 4 on it relative to the separation box 3 allows the cleaning brush 41 on the cleaning assembly 4 to move further towards the inner wall of the separation box 3 under the action of centrifugal force, so that the cleaning brush 41 can abut against the inner wall with greater force, thereby improving the cleaning effect and efficiency. When the fixed rod 44 and the separation box 3 rotate in the same direction, in order to avoid the cleaning component 4 on the fixed rod 44 being unable to clean the inner wall due to the relative stationary position of the cleaning component 4 and the separation box 3, the rotation speed of the drive device is set to ensure that the rotational angular velocities of the fixed rod 44 and the separation box 3 are different. This ensures that the cleaning component 4 on the fixed rod 44 and the separation box 3 have relative motion, so that the cleaning component can clean the inner wall of the separation box 3 normally.

[0065] In one embodiment of the present invention, the solid-liquid separation device further includes a fixing plate 2, and the housing 1 is disposed on the fixing plate 2.

[0066] In the above technical solution, the fixing plate 2 serves as the supporting foundation for the housing 1, and its main purpose is to improve the stability of the entire solid-liquid separation device. Industrial production environments are often complex, such as uneven ground and equipment vibration. The design of the fixing plate 2 can effectively disperse and mitigate the impact of these external factors on the housing 1, ensuring the stability of the housing 1 during high-speed operation and avoiding a decrease in separation efficiency or equipment damage caused by vibration.

[0067] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The main function of the housing 1 is to provide a closed working environment to accommodate the solid-liquid separation components such as the separation tank 3 and the cleaning component 4, while collecting the separated liquid. The separation tank 3 is used to achieve solid-liquid separation. When the separation tank 3 rotates, the water in the material is thrown out through the filter holes on the side wall of the separation tank 3, while the material is blocked, thereby achieving the effect of solid-liquid separation. The cleaning component 4 is mainly used inside the separation tank 3 to clean the material remaining on the inner wall of the separation tank 3, preventing these particles from clogging the separation holes or corroding the housing. Among them, the cleaning brush 41 can directly contact the inner wall of the separation tank 3 or maintain a sufficiently small gap with the inner wall, thereby sweeping off the material remaining or adhering to the inner wall, achieving the cleaning effect. The function of the pushing component is to adjust the distance between the cleaning brush 41 and the separation box 3, ensuring that the cleaning brush 41 can always clean the inner wall of the separation box 3. Even if the cleaning brush 41 wears down after prolonged use, the pushing component can adjust the position of the cleaning brush 41, moving it closer to the inner wall until it reaches a position where it can continue cleaning the inner wall of the separation box 3, thus ensuring cleaning effectiveness. By setting up the pushing component, the cleaning brush 41 can always be in a position where it can sweep and clean the inner wall of the separation box 3. Even after the bristles of the cleaning brush 41 wear down due to prolonged cleaning, the pushing component can still push the cleaning brush 41 to remain in the cleaning position, thus ensuring cleaning effectiveness and avoiding problems such as clogging and reduced separation efficiency.
