Description

Technical Field

[0001] This invention relates to the field of filtration technology, and in particular to a tea clarification and filtration device for tea beverage production. Background Technology

[0002] In the industrial production of tea beverages, tea extraction requires clarification and filtration to remove tea residue, particles, and some large molecules, ensuring the clarity and stability of the final product. Commonly used filtration equipment includes plate and frame filters, membrane filtration systems, and disc centrifuges. These devices typically consist of a filter chamber, filter media, inlet and outlet pipes, and a drive pump. The tea liquor passes through the filter media under pressure or centrifugal force, while solid impurities are retained, and the clarified liquid is discharged from the outlet. However, in actual production, not all tea beverage products require the same level of filtration. Some products require high-precision clarification, while others need to retain a certain degree of turbidity and flavor compounds. For example, the requirements for filtration precision vary greatly depending on whether it's a fresh tea or a blended tea beverage, or even when processing different formulas on the same production line at different times. However, once most existing filtration equipment is installed and debugged, the filter media is fixed inside the equipment. As long as the tea soup enters the equipment, it will inevitably be filtered. To switch to the non-filtering mode, the entire production line must be stopped, the filter components must be manually disassembled, or the pipeline must be reconnected to the bypass circuit. The whole process takes a long time, and frequent disassembly and assembly can easily damage the sealing of the filter media, increasing the cost of consumables. Summary of the Invention

[0003] If the equipment itself lacks the ability to quickly switch between filtered and non-filtered states, it will limit the flexible scheduling capabilities of the production line and affect overall efficiency. If a filtration device could be designed that allows operators to switch between filtration states directly according to product needs without disassembling the machine or stopping production, the flexibility and convenience of tea beverage production would be greatly improved.

[0004] To address the aforementioned technical problems, this invention discloses a tea infusion clarification and filtration device for tea beverage production, comprising a material cylinder, a discharge pipe mounted on one side of the material cylinder, and further comprising:

[0005] The extraction component is located inside the material barrel, and its position can be adjusted by raising and lowering.

[0006] A filter assembly, disposed within the discharge pipe, comprises:

[0007] A long filter tube is rotatably installed inside the discharge pipe;

[0008] The short filter tube is rotatably connected to the long filter tube via a connecting ring.

[0009] The lever is hinged to the short filter tube and connected to the short filter tube by a torsion spring. In its natural state, the lever is perpendicular to the axis of the short filter tube.

[0010] A filter screen is slidably installed inside a long filter tube. An elastic component inside the long filter tube causes the filter screen to adhere to a connecting ring. The tail of a lever abuts against the filter screen. When the lever is not perpendicular to the axis of the short filter tube, it causes the filter screen to move away from the connecting ring. This technical solution allows for more convenient control by adjusting the position of the short filter tube to select whether or not to filter. When the short filter tube is completely inside the feed cylinder, and the lever is perpendicular to its axis, the filter screen adheres to the connecting ring for filtration. When the lever is inside the discharge pipe, the filter screen is away from the connecting ring, and filtration is not possible.

[0011] Furthermore, the elastic component includes a retaining ring, which is fixedly installed inside the long filter tube, and a large spring is fixedly mounted on the retaining ring, which is fixedly connected to the filter screen.

[0012] Furthermore, a connecting shaft is slidably mounted on the end face of the long filter tube, and a small spring is fixedly mounted between the connecting shaft and the long filter tube. The short filter tube has a semi-circular hole, and the end of the connecting shaft is inserted into the semi-circular hole.

[0013] Furthermore, the filter screen has a notch on its circumference. When the filter screen is in contact with the connecting ring, the notch is completely blocked by the side of the connecting ring. A cleaning rod is hinged to the lever, and a torsion spring is installed between the lever and the cleaning rod.

[0014] Furthermore, a wide groove is provided at the connection between the discharge pipe and the material cylinder. The diameter of the wide groove is larger than the inner diameter of the discharge pipe. Multiple stop bars are provided within the wide groove. The lever abuts against the wide groove. When the long filter pipe drives the short filter pipe and the lever to rotate, the lever is locked to one side of the stop bar. Through this technical solution, and with the cooperation of the connecting shaft, the rotation of the long filter pipe can drive the rotation of the short filter pipe. However, if the lever is locked, only the long filter pipe and the filter screen rotate, without driving the short filter pipe. At this time, the lever and the cleaning rod also remain stationary. The cleaning rod adheres to the filter screen, enabling the cleaning of the side of the filter screen.

[0015] Furthermore, a stirring rod is rotatably mounted at the bottom of the material cylinder. The lever is completely perpendicular to the axis of the short filter tube, and when it rotates, it drives the stirring rod to rotate. Through the above technical solution, the rotation of the stirring rod can stir the slurry in the material cylinder, ensuring uniform discharge. Moreover, it is controlled by the filter assembly, requiring no additional power source, resulting in a high degree of automation, simplicity, stability, and cost savings.

[0016] Furthermore, it also includes a separation component, which includes a centrifuge barrel fixedly installed inside a long filter tube. The centrifuge barrel has a smaller inner diameter at the end closer to the filter component and a larger inner diameter at the end farther away from the filter component. The centrifuge barrel is equipped with multiple long plates inside.

[0017] Furthermore, an outer cylinder is fixedly installed at the end of the centrifuge with a larger inner diameter. A second discharge pipe is provided on the lower side of the outer cylinder. An inner cylinder is fixedly installed inside the outer cylinder, and a first discharge pipe is provided on the lower side of the inner cylinder. The diameter of the inner cylinder is smaller than that of the outer cylinder. Through the above technical solution, when the centrifuge rotates, the solids can adhere more closely to the inner wall of the centrifuge. The solids, adhering to the inner wall, enter the outer cylinder, while the liquid enters the inner cylinder from the middle to complete the separation. The long plate drives the slurry inside the centrifuge to rotate at a faster speed, making it easier to achieve solid-liquid separation.

[0018] Furthermore, the extraction assembly includes a central tube, which is slidably installed inside the material cylinder. A long tube is fixedly installed on the lower side of the central tube, a vertical tube is fixedly installed on the lower side of the long tube, a short tube is fixedly installed on the lower side of the vertical tube, and an extraction box is fixedly installed at one end of the short tube. An iron mesh is provided on the extraction box, and tea leaves are placed inside the extraction box.

[0019] Furthermore, an inner pipe is connected to one side of the short pipe, and water flows out tangentially along the inner circumference of the extraction tank. An annular pipe is connected to the central pipe, and a top-layer pipe is connected to the annular pipe. A spray nozzle is installed on the lower side of the top-layer pipe. Through the above technical solution, the tea leaves inside the extraction tank are rinsed at different angles, and as the liquid level in the barrel rises, the extraction tank also rises, ensuring that the hot water can vigorously brew the tea leaves, ultimately achieving complete immersion and heating, thus improving the extraction efficiency.

[0020] The beneficial effects of this invention compared to the prior art are:

[0021] (1) Through the technical solution of the present invention, filtration or non-filtration can be selected by controlling the position of the short filter tube, which makes the control more convenient. The short filter tube is completely located inside the material cylinder, the lever is perpendicular to the axis of the short filter tube, and the filter screen is attached to the connecting ring for filtration. When the lever is located inside the discharge pipe, the filter screen is far away from the connecting ring, and filtration is not possible. At the same time, this switching method can be achieved by simply changing the axial position of the short filter tube without disassembling any parts. The operation response is rapid, and the boundary between the two states of filtration and non-filtration is clear, avoiding misoperation. In the filtration state, the filter screen is tightly attached to the connecting ring, which effectively prevents the slurry from leaking directly without filtration and ensures the reliability of the filtration effect. In the non-filtration state, the filter screen is completely detached from the connecting ring, and the channel is unobstructed, which is conducive to the rapid discharge of impurities during large-flow discharge or cleaning, further improving the applicability and maintenance convenience of the equipment.

[0022] (2) Through the technical solution of the present invention, the long filter tube can rotate and drive the short filter tube to rotate when the connecting shaft is engaged. However, if the lever is stuck, the long filter tube and the filter screen will rotate without driving the short filter tube. At this time, the lever and the cleaning rod will also not move. The cleaning rod will be in contact with the filter screen and can clean the side of the filter screen. This overload protection relative rotation structure can not only avoid damage to parts caused by forced drive when the lever is stuck, thus extending the service life of the short filter tube and the lever, but also keep the cleaning rod and the filter screen in relative motion. During the rotation of the filter screen, the slurry deposits attached to the side are continuously scraped off, effectively reducing the frequency of filter screen clogging and maintaining stable filtration throughput. At the same time, since the lever is stationary and the position of the cleaning rod is fixed, the entire side of the filter screen can be cleaned evenly, avoiding local residue, reducing the number of times the machine needs to be stopped for cleaning, and increasing the continuous operation time.

[0023] (3) Through the technical solution of the present invention, the rotation of the stirring rod can stir the slurry in the barrel, ensuring uniform discharge. It is controlled by the filter assembly, without the need for an additional power source, has a high degree of automation, and is simple, stable, and cost-effective. In addition, the linkage design between the stirring rod and the filter assembly allows the stirring action and the filtration switching action to be carried out in tandem, without the need to set separate control steps, thus simplifying the operation process. Since no external power components are required, electrical fault points and energy loss are also reduced, making the equipment operation more reliable. At the same time, the overall structure is compact, occupies little space, reduces the difficulty of manufacturing and assembly, and facilitates daily maintenance and parts replacement. Long-term use can effectively reduce operation and maintenance costs.

[0024] (4) Through the technical solution of the present invention, when the centrifuge barrel rotates, the solids can adhere more closely to the inner wall of the centrifuge barrel. The solids adhere to the inner wall and enter the outer cylinder, while the liquid enters the inner cylinder from the middle to complete the separation. The long plate drives the slurry in the centrifuge barrel to rotate faster, making it easier to achieve solid-liquid separation. Moreover, while the long plate drives the slurry to accelerate, it can generate a strong radial pushing effect on the slurry, causing the solid particles to migrate quickly to the inner wall of the centrifuge barrel, shortening the separation time and increasing the throughput per unit time. The solid layer attached to the inner wall of the centrifuge barrel can be smoothly discharged to the outer cylinder under the action of continuous rotation and gravity, avoiding excessive accumulation of solids in the barrel and ensuring the continuity of the separation process. The liquid flows smoothly into the inner cylinder from the middle area, with a short flow path and no interference from solids, effectively improving the clarity of the separated liquid and significantly enhancing the overall separation efficiency.

[0025] (5) Through the technical solution of the present invention, the tea leaves inside the extraction box are rinsed at different angles, and the extraction box rises as the liquid level in the barrel rises, ensuring that the hot water can vigorously steep the tea leaves and eventually fully soak and heat up, thus improving the extraction efficiency. At the same time, the design of the extraction box automatically rising with the liquid level allows the rinsing angle and height to dynamically adapt to changes in liquid level, ensuring that the tea leaves are subjected to sufficient and varied water flow impact at different extraction stages, promoting the rapid dissolution of effective components inside the tea leaves; during the process of the liquid level rising, the extraction box gradually floats up, and the hot water continuously tumbles the tea leaves from multiple angles, avoiding the deposition and caking of the tea leaves and improving the uniformity of extraction; when fully soaked, the tea leaves are in full contact with the hot water, and the heat transfer is more uniform, reducing the phenomenon of local overheating or insufficient extraction, thereby obtaining a higher concentration of extract in the same time, significantly improving the extraction quality and raw material utilization rate.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] like Figures 1-10As shown, a tea clarification and filtration device for tea beverage production includes a material cylinder 6, a cover plate 7 fixed to the material cylinder 6 by bolts, a pipe receiving assembly 2 mounted on the cover plate 7, and a discharge pipe 8 mounted on one side of the material cylinder 6. This embodiment also includes an extraction assembly 1 disposed within the material cylinder 6 and a filtration assembly 5 disposed within the discharge pipe 8. The extraction assembly 1 is capable of moving up and down, and is controlled by the pipe receiving assembly 2. The extraction assembly 1 contains tea leaves and is raised to different heights according to the water level in the material cylinder 6. Specifically, the extraction assembly 1 includes a central tube 108, which is slidably installed within the material cylinder 6, specifically at the center of the cover plate 7. The lower side of the central tube 108 is fixed. There are four long tubes 105, arranged in a cross shape. Each long tube 105 has a vertical tube 103 fixedly attached to its lower side, and a short tube 102 fixedly attached to its lower side. One end of all the short tubes 102 is fixed to the extraction box 101. The extraction box 101 has an opening at the top and is equipped with an iron mesh 110. Tea leaves are placed inside the extraction box 101. A central rod 111 is fixedly attached to the center of the extraction box 101 and is fixedly connected to the iron mesh 110. In this embodiment, water flows from the central tube 108 through the long tubes 105, the vertical tubes 103, and the short tubes 102 and finally enters the extraction box 101. However, the angle of the water entering the extraction box 101 must be constrained.

[0045] In this embodiment, to constrain the flow direction of water entering the extraction tank 101, an inner pipe 109 is provided. The inner pipe 109 is connected to one side of the short pipe 102, and water flows out tangentially along the inner circumferential surface of the extraction tank 101. Simultaneous water flow allows the water inside the extraction tank 101 to rotate, carrying the tea leaves and rinsing them. To further facilitate this, a water flow from another direction is added. Specifically, a ring-shaped pipe 502 is connected to the central pipe 108, and a top-layer pipe 106 is connected to the ring-shaped pipe 107. A spray nozzle is installed on the lower side of the top-layer pipe 106. Water also flows vertically downwards through the spray nozzle, directly passing through the iron mesh 110 and entering the extraction tank 101, impacting the tea leaves. This rinsing of the tea leaves inside the extraction tank 101 is achieved at different angles. Furthermore, as the liquid level in the feed cylinder 6 rises, the extraction tank 101 also rises, ensuring that the hot water vigorously steeps the tea leaves, ultimately achieving complete immersion and heating, thus improving extraction efficiency.

[0046] In this embodiment, the tube receiving assembly 2 includes a gearbox 203, which is fixedly mounted on the cover plate 7. The first end of the gearbox 203 is connected to a motor 204, which is also fixedly mounted on the cover plate 7. The motor 204 serves as the power source input. The other end of the gearbox 203 is equipped with roller 1 201 and roller 2 202, which clamp the central tube 108 and drive the central tube 108 to rise and fall, thereby driving the entire extraction assembly 1 to rise and fall. In other embodiments, gear rack, pinion screw and nut or similar solutions can also be used to achieve the lifting and falling. This is a simple technology and will not be described in detail.

[0047] In this embodiment, the filter assembly 5 includes a long filter tube 501, a short filter tube 503, and a lever 505. The long filter tube 501 is rotatably installed inside the discharge pipe 8. Specifically, the long filter tube 501 is rotated by a rotating assembly 4. The short filter tube 503 is rotatably connected to the long filter tube 501 by a connecting ring 502. That is, the long filter tube 501 and the short filter tube 503 are axially fixed and can only rotate relative to each other. The lever 505 is hinged to the short filter tube 503 and is connected to the short filter tube 503 by a torsion spring 504. In its natural state, the lever 505 is perpendicular to the axis of the short filter tube 503. The natural state refers to the situation where no external force is applied and the torsion spring 504 does not store force.

[0048] In this embodiment, the filter screen 507 is slidably installed inside the long filter tube 501. An elastic component inside the long filter tube 501 drives the filter screen 507 to adhere to the connecting ring 502. The tail of the lever 505 abuts against the filter screen 507. When the lever 505 is not perpendicular to the axis of the short filter tube 503, it drives the filter screen 507 away from the connecting ring 502. Through the above technical solution, filtering or not filtering can be selected by controlling the position of the short filter tube 503, making control more convenient. When the short filter tube 503 is completely located inside the material cylinder 6, and the lever 505 is perpendicular to the axis of the short filter tube 503, the filter screen 507 adheres to the connecting ring 502 for filtering. When the lever 505 is located inside the discharge pipe 8, the filter screen 507 is away from the connecting ring 502, and filtering is not possible.

[0049] In this embodiment, the elastic component includes a retaining ring 509, which is fixedly installed inside the long filter tube 501. A large spring 508 is fixedly mounted on the retaining ring 509 and is fixedly connected to the filter screen 507. A connecting shaft 510 is slidably mounted on the end face of the long filter tube 501. A small spring 511 is fixedly mounted between the connecting shaft 510 and the long filter tube 501. A semi-circular hole is provided on the short filter tube 503, and the end of the connecting shaft 510 is inserted into the semi-circular hole. When the short filter tube 503 and the lever 505 are not subjected to much resistance, the long filter tube 501 can drive the short filter tube 503 to rotate. If it is subjected to greater resistance, the connecting shaft 510 is compressed through the semi-circular hole, causing the long filter tube 501 and the short filter tube 503 to move relative to each other. That is, the short filter tube 503 does not rotate while the long filter tube 501 rotates. The filter screen 507 has a notch on its circumference. When the filter screen 507 is in contact with the connecting ring 502, the notch is completely blocked by the side of the connecting ring 502. The cleaning rod 506 is hinged to the lever 505, and a torsion spring 512 is installed between the lever 505 and the cleaning rod 506. During filtration, the particles in the slurry are needed, but larger particles and tea leaves must be kept out. Therefore, the material in the mixing drum 6 needs to be thoroughly stirred, while large residues are filtered out through the filter screen 507. If it is fruit tea or tea containing fruit pulp or pieces, then filtration is not possible. To ensure a certain amount of particles, the filter screen 507 is moved away from the connecting ring 502, allowing larger particles such as fruit pulp and pieces to pass through the edge notch of the filter screen 507. In short, this method is suitable for situations where stirring and filtration are not required.

[0050] In this embodiment, a wide groove 9 is provided at the connection between the discharge pipe 8 and the material cylinder 6. The diameter of the wide groove 9 is larger than the inner diameter of the discharge pipe 8. Multiple baffles 10 are provided in the wide groove 9. The lever 505 abuts against the wide groove 9. When the long filter pipe 501 drives the short filter pipe 503 and the lever 505 to rotate, the lever 505 is stuck on one side of the baffle 10. When lever 505 abuts against wide slot 9, it is in the state of cleaning filter screen 507. At this time, the rotation of long filter tube 501 will tend to drive short filter tube 503. However, lever 505 on short filter tube 503 is blocked by stop bar 10 and cannot move. Lever 505 and cleaning rod 506 do not move. Only long filter tube 501 drives filter screen 507 to rotate. At this time, cleaning rod 506 will adhere to the side of filter screen 507 for cleaning. This can be adjusted by torsion spring 512. Through the above technical solution and the cooperation of connecting shaft 510, when long filter tube 501 rotates, it can drive short filter tube 503 to rotate. However, if lever 505 is blocked, long filter tube 501 and filter screen 507 rotate, but short filter tube 503 is not driven. At this time, lever 505 and cleaning rod 506 do not move. Cleaning rod 506 adheres to filter screen 507 and can clean the side of filter screen 507.

[0051] In this embodiment, a stirring rod 11 is rotatably mounted at the bottom of the material cylinder 6. When the lever 505 is completely perpendicular to the axis of the short filter tube 503 and rotates, it drives the stirring rod 11 to rotate. In order to allow the four levers 505 to drive the stirring rod 11, the spacing of the stirring rods 11 is designed so that each lever 505 can actuate one tooth of the stirring rod 11. Therefore, the levers 505 are completely inside the material cylinder 6. When the short filter tube 503 drives the levers 505 to rotate, it also drives the stirring rod 11 to rotate and stir the slurry in the material cylinder 6. The rotation of the stirring rod 11 can stir the slurry in the material cylinder 6, ensuring uniform discharge. And it is controlled by the filter assembly 5, without the need for an additional power source, with a high degree of automation, and is simple, stable and cost-effective.

[0052] In this embodiment, a separation component 3 is also included. The separation component 3 includes a centrifuge tank 301, which is fixedly installed inside a long filter tube 501. The inner diameter of the centrifuge tank 301 is smaller at the end closer to the filter component 5 and larger at the end farther away from the filter component 5. Multiple long plates 302 are provided inside the centrifuge tank 301. An outer cylinder 304 is fixedly installed at the end of the centrifuge tank 301 with a larger inner diameter. A second discharge pipe 306 is provided on the lower side of the outer cylinder 304. An inner cylinder 303 is fixedly installed inside the outer cylinder 304 and is fixed by a connecting rod 307. A first discharge pipe 305 is provided on the lower side of the inner cylinder 303. The diameter of the inner cylinder 303 is smaller than the diameter of the outer cylinder 304. When the centrifuge tank 301 rotates, the solids can adhere more closely to the inner wall of the centrifuge tank 301. The solids, adhering to the inner wall, enter the outer cylinder 304, while the liquid enters the inner cylinder 303 from the middle to complete the separation. The long plates 302 drive the slurry inside the centrifuge tank 301 to rotate faster, making it easier to achieve solid-liquid separation.

[0053] Both the separation component 3 and the filter component 5 need to rotate during operation. Specifically, they are driven by a rotating component 4. The rotating component 4 includes a fixed plate 401, a small motor 403 fixedly mounted on the lower side of the fixed plate 401, a drive gear 402 fixedly mounted on the shaft of the small motor 403, a keyway on the long filter tube 501, and a driven gear 404 connected to the long filter tube 501 via a spline. The driven gear 404 is rotatably mounted on the fixed plate 401 and meshes with the drive gear 402. The small motor 403 drives the drive gear. When gear 402 rotates, the driving gear 402 drives the driven gear 404 to rotate, and the long filter tube 501 can also slide within the driven gear 404. A guide rod 406 and a lead screw 407 are fixedly mounted on the fixed plate 401. A movable plate 405 is slidably mounted on the guide rod 406. A nut 408 is rotatably mounted on the movable plate 405. The nut 408 cooperates with the lead screw 407 to control the position of the movable plate 405. The movable plate 405 is rotatably connected to the long filter tube 501 and is axially fixed. That is, when the movable plate 405 moves, it will move the long filter tube 501.

[0054] Working principle: First, place tea leaves or other raw materials into the extraction box 101, then fix the iron mesh 110. Next, place the entire extraction assembly 1 into the material cylinder 6. Secure the upper part of the central tube 108 between roller 1 201 and roller 2 202. Pour water into the central tube 108. The water flows through the long tube 105 into the vertical tube 103, then through the vertical tube 103 into the short tube 102, and through the short tube 102 into the inner tube 109. The water then tangentially impacts the tea leaves inside the extraction box 101 along the extraction box 101. A sealing head 104 is fixedly installed on the upper part of the pipe 103 to seal it and prevent water leakage. Water also enters the top pipe 106 through the annular pipe 107, and then impacts downward from the nozzle, impacting the tea leaves inside the extraction box 101. As the water level increases, the water will flow out of the extraction box 101 and into the material cylinder 6. Then the water level in the material cylinder 6 rises, and the central pipe 108 is also pulled upward through the pipe take-up assembly 2 to prevent the entire extraction box 101 from being submerged in water and reduce the impact force. After continuous heating and cooling, the extraction is completed, and then it is taken out through the discharge pipe 8.

[0055] Move the movable plate 405 to bring the filter assembly 5 closer to the fixed plate 401, then slide the movable plate 405 onto the guide rod 406, using the nut 408 to control its position and fix it. Assuming that stirring and filtration are needed inside the material cylinder 6, fully extend the lever 505 into the material cylinder 6. At this point, driven by the torsion spring 504, the lever 505 is perpendicular to the axis of the short filter tube 503. The lever 505 then engages with the stirring rod 11, starting the small motor 403. The small motor 403 drives the drive gear 402, which in turn drives the driven gear 404 to rotate. The driven gear 404 then drives the long filter tube 50... 1. Rotation: The long filter tube 501 drives the short filter tube 503, which in turn drives the lever 505 to rotate. The lever 505 drives the stirring rod 11 to rotate, stirring the slurry in the material cylinder 6. The slurry then enters the short filter tube 503, passes through the filter screen 507, and enters the long filter tube 501. It then enters the centrifuge tank 301. Since the long filter tube 501 continues to rotate, it drives the long filter tube 501 and the connecting ring 502. At this position, high-speed centrifugation and solid-liquid separation are completed. The solid enters the outer cylinder 304 and flows out from the second discharge pipe 306, while the liquid enters the inner cylinder 303 and flows out from the first discharge pipe 305, thus completing the filtration and separation.

[0056] If stirring and filtration are not required, then let the lever 505 remain inside the discharge pipe 8. At this time, the lever 505 is forced to a position nearly parallel to the axis of the short filter tube 503. Then, the tail of the lever 505 will abut against the filter screen 507, allowing a gap to flow between the filter screen 507 and the connecting ring 502. The slurry will flow out from the gap in the filter screen 507 without filtration. If it is necessary to clean the side of the filter screen 507, let the lever 505 remain inside the wide groove 9. Then, the long filter tube 501 rotates, driving the short filter tube 503. The short filter tube 503 drives the lever 505, and the lever 505 is stuck on the side of the stop bar 10. After that, the short filter tube 503 will no longer rotate, and the cleaning rod 506 will adhere to the filter screen 507. The rotation of the filter screen 507 will perform cleaning.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
