Description

Technical Field

[0001] This invention relates to the field of magnetic pump technology, and more specifically to a corrosion-resistant dry-run magnetic vane pump. Background Technology

[0002] Dry-run magnetic pumps are a new type of magnetic pump that integrates magnetic drive technology and vane pump structural features. They are corrosion-resistant and can operate for extended periods without liquid. Thanks to their unique working principle and advantages, they play an important role in many working conditions. Because they use magnetic drive to achieve contactless power transmission, they avoid the liquid leakage problems caused by seal wear in traditional mechanical seal pumps. They are particularly suitable for conveying liquids with special properties such as corrosiveness, toxicity, flammability, explosiveness, and containing particulate impurities.

[0003] The filters in existing magnetic pumps are generally installed as a single unit. When transporting liquids containing particulate impurities, after a period of use, the particulate impurities will clog the filter in large quantities, resulting in a reduction in water intake. This requires staff to disassemble the filter for replacement and cleaning, which is not only cumbersome and increases labor intensity, but also reduces the efficiency of equipment operation.

[0004] Therefore, the present invention provides a corrosion-resistant dry-running magnetic vane pump to solve the above-mentioned problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a corrosion-resistant dry-running magnetic vane pump, which effectively solves the problem that after a period of use, the filter in the existing magnetic pump will be heavily clogged by particulate impurities, resulting in a reduction in water intake.

Because the curved plate continuously cleans the outside of the hemispherical filter screen, it will not cause a reduction in water volume.

[0018] 3.

Detailed Implementation

[0022] The following reference Figures 1 to 12The various embodiments of the present invention will be described in detail. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] A corrosion-resistant, dry-running magnetic vane pump, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, the system includes a support cover 1. The front end of the support cover 1 has a hollow cavity structure. An outer magnetic rotor 2 is rotatably mounted inside the cavity of the support cover 1. The front ends of the outer magnetic rotor 2 and the isolation sleeve 3 are respectively provided with hollow structures. The isolation sleeve 3 is installed inside the front end of the outer magnetic rotor 2. The isolation sleeve 3 adopts the existing installation method. An inner magnetic rotor 4 is rotatably mounted inside the isolation sleeve 3. A pump housing 5 is installed at the front end of the support cover 1. The pump housing 5 has a hollow cavity structure that runs from front to back. A sealing cover 6 is fixedly installed at the rear end of the pump housing 5. The sealing cover 6 has a shaft hole. A rotor shaft 7 is coaxially fixedly mounted on the shaft of the inner magnetic rotor 4. One end of the rotor shaft 7 rotates... The rotor shaft 7 is rotatably installed in the shaft hole, and a sealing ring is installed between the shaft hole and the rotor shaft 7. A water outlet flange 8 is fixedly installed at the top of the pump casing 5, communicating with the interior of the pump casing 5. A water inlet pipe 9 is fixedly installed at the left end of the pump casing 5, communicating with the interior of the pump casing 5. A cleaning assembly is provided at the left end of the water inlet pipe 9, which can filter impurities in the liquid. A water inlet flange 10 is installed at the left end of the cleaning assembly, communicating with the cleaning assembly. A rotor wheel 11 is rotatably installed inside the pump casing 5, positioned above the eccentricity of the pump casing 5. The rotor shaft 7 and the rotor wheel 11 are coaxially and fixedly connected, as detailed below. Figure 3 As shown, multiple internal cavities 12 are evenly provided on the circumferential end of the rotor wheel 11. Here, there are six internal cavities 12. A push rod 13 is fixedly installed on the inner wall of each internal cavity 12. A sliding plate 14 is slidably sleeved on each push rod 13. The sliding plate 14 can be close to or away from the center of the rotor wheel 11. A bearing cover 15 is installed at the front end of the pump housing 5. A positioning key is fixedly installed on the outer side of the front side of the rotor shaft 7. A central hole is provided at the center of the rotor wheel 11. A keyway is provided on the inner wall of the central hole. During the installation of the magnetic vane pump, the operator holds the outer magnetic rotor 2 and installs it inside the bracket cover 1. The isolation sleeve 3 is installed inside the outer magnetic rotor 2, and the inner magnetic rotor 4 is installed inside the isolation sleeve 3. One end of the rotor shaft 7 is inserted into the shaft hole of the sealing cover 6. Bolts are then used to fix the front end of the bracket cover 1 to the sealing cover 6. Next, the vane 14 is fitted onto the corresponding push rod 13, and the vane 14 slides in contact with the inner cavity 12. The rotor shaft 7 is inserted into the center hole, and the positioning key is installed in the keyway, thus realizing the connection between the rotor wheel 11 and the rotor shaft 7. The fixed connection between them improves the stability of the rotor wheel 11. Since the rotor wheel 11 is set above the eccentric part of the pump casing 5, the cavity of the pump casing 5 below the rotor wheel 11 is larger. Then, the bearing cover 15 is fixedly connected to the front end of the pump casing 5 with bolts. Since the bearing cover 15 has a positioning hole inside, the front end of the rotor shaft 7 is rotatably connected in the positioning shaft hole of the bearing cover 15. Then, the reducer is connected to the motor shaft. The reducer is coaxially fixedly connected to the external magnetic rotor 2 through a coupling, thus completing the installation of the magnetic vane pump. The magnetic vane pump in this application can also be replaced by a magnetic pump in the prior art, such as the magnetic pump of the BAYSTER BTGM series. The bracket cover 1, pump housing 5, sealing cover 6, rotor shaft 7, outlet flange 8, inlet pipe 9, rotor wheel 11, bearing cover 15, bolts and other components are made of existing materials, such as 316SS stainless steel, which has a corrosion-resistant effect. The vane 14 is made of existing materials, such as PTFE. The isolation sleeve 3 is made of existing materials, such as one layer of PEEK material and the other layer of PTFE material. During use, the motor, reducer, bracket cover 1, and pump casing 5 are fixedly installed in their respective positions. The power is turned on, and the controller starts the motor to rotate. The reducer drives the outer magnetic rotor 2 to rotate through the coupling. The magnetic field penetrates the air gap and the isolation sleeve 3, driving the inner magnetic rotor 4 to rotate. The rotor shaft 7 drives the rotor wheel 11 to rotate. During the rapid rotation of the rotor wheel 11, due to the centrifugal force, one end of each vane 14 will slide against the inner wall of the pump casing 5, thereby increasing the cavity between the two vanes 14 at the inlet pipe 9 port to increase liquid suction and decreasing the cavity between the two vanes 14 at the outlet flange 8 port to decrease liquid discharge, so that the liquid is continuously discharged outward. Since the magnetic vane pump completely abandons the traditional mechanical seal and transmits torque through the magnetic field penetrating the isolation sleeve 3, it achieves zero leakage in media transportation, completely solving the shaft seal leakage problem of traditional pumps. In addition, the cleaning component can filter impurities in the liquid, improving the cleanliness of the liquid.

[0024] like Figure 2 , Figure 3 , Figure 5 , Figure 9 , Figure 11As shown, the cleaning assembly includes an outer shell 16. The left end of the water inlet pipe 9 is fixedly connected to the outer shell 16. The inner diameter of the outer shell 16 is larger than the inner diameter of the water inlet pipe 9. A tapered pipe 17 is fixedly connected to the left end of the outer shell 16. The inner diameter of the tapered pipe 17 is smaller than the inner diameter of the outer shell 16. A water inlet flange 10 is fixedly connected to the left end of the tapered pipe 17. The inner diameter of the cavity of the water inlet flange 10 is smaller than the inner diameter of the tapered pipe 17, and the inner diameter of the cavity of the water inlet flange 10 is the same as the inner diameter of the water inlet pipe 9. The tapered pipe 17... An impurity ring 18 is fixedly installed on the inner wall. An impurity groove is opened at the left end of the impurity ring 18. Multiple first impurity holes are evenly opened on the impurity groove. A hemispherical shell filter screen 19 is fixedly installed at the left end of the impurity ring 18. The impurity groove is located on the outer edge of the hemispherical shell filter screen 19. The hemispherical shell filter screen 19 protrudes to the left. Multiple second impurity holes are evenly opened on the hemispherical shell filter screen 19. The inner diameter of the second impurity holes is the same as the inner diameter of the first impurity holes. A cross 20 is fixedly installed at the right end of the impurity ring 18.

[0025] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 11 As shown, a drain pipe 21 is fixedly connected to the inlet flange 10. A top pipe 22 is fixedly connected to the top of the outer shell 16. A water turbine box 23 is fixedly connected to the top of the top pipe 22. A drive water turbine 24 is rotatably mounted on the inner top of the water turbine box 23. The drive water turbine 24 is a water turbine of the prior art, meaning that water can drive the drive water turbine 24 to rotate. A left isolation plate 25 is fixedly and sealed on the inner wall of the left end of the outer shell 16. A cavity is provided between the left isolation plate 25 and the right side of the tapered pipe 17. An isolation ring 26 is fixedly installed between the left end of the left isolation plate 25 and the right end of the tapered pipe 17. The inner diameter of the isolation ring 26 is larger than the outer diameter of the tapered pipe 17, and the outer diameter of the isolation ring 26 is smaller than the outer diameter of the left isolation plate 25. A bevel gear set 27 is installed on the cross 20. The bevel gear set 27 includes two cones. A gear and an L-shaped block are fixedly installed at the middle of the right end of the cross 20. Two bevel gears are rotatably installed on the L-shaped block and mesh with each other. A water turbine shaft 28 is coaxially fixedly installed at the lower end of the drive water turbine 24. A positioning hole is opened at the top of the isolation ring 26. The lower end of the water turbine shaft 28 extends through the top tube 22 and the positioning hole into the cavity between the left isolation plate 25 and the conical tube 17. The inner diameter of the top tube 22 is larger than the inner diameter of the water turbine shaft 28 to facilitate the flow of water. An insert shaft 29 is rotatably installed through the center end of the hemispherical filter screen 19. The right end of the insert shaft 29 is coaxially fixedly connected to one of the bevel gears. A curved plate 30 is fixedly installed at the left end of the insert shaft 29. The curved plate 30 slides in contact with the outside of the hemispherical filter screen 19. The curved plate 30 has an arc-shaped strip structure.

[0026] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 As shown, a middle isolation plate 31 located to the right of the left isolation plate 25 is fixedly installed on the inner wall of the outer shell 16. A left water inlet hole 32 that runs through the left and right sides is opened at the upper end of the middle isolation plate 31. A left drain pipe 33 is fixedly connected to the upper end of the left isolation plate 25. The right end of the left drain pipe 33 is fixedly installed on the middle isolation plate 31 and communicates with the left water inlet hole 32. A right isolation plate 34 located to the right of the middle isolation plate 31 is fixedly installed on the inner wall of the outer shell 16. A right water inlet hole 35 is opened at the upper end of the right isolation plate 34. The left water inlet hole 32 is concentrically arranged with the left water inlet hole 32. A dirt removal component is provided between the right isolation plate 34 and the middle isolation plate 31. A bent pipe 36 is fixedly installed at the right end of the right isolation plate 34. The right end of the bent pipe 36 is fixedly installed on the left end of the water inlet pipe 9. The right water inlet hole 35, the water inlet pipe 9, and the bent pipe 36 are interconnected.

[0027] like Figure 4 , Figure 5 As shown, a one-way valve 37 is provided at the bottom of the isolation ring 26. The number of one-way valves 37 can be set as needed. A water storage chamber 38 is provided between the outer side of the isolation ring 26 and the inner wall of the outer shell 16. A left miscellaneous chamber 39 is provided between the left isolation plate 25 and the middle isolation plate 31. The left drain pipe 33 is provided in the left miscellaneous chamber 39. A right miscellaneous chamber 40 is provided on the right side of the middle isolation plate 31. A curved pipe 36 is provided in the right miscellaneous chamber 40. Install the liquid pipe on the inlet flange 10, turn on the power, and the controller starts the motor to rotate. The reducer drives the outer magnetic rotor 2 to rotate through the coupling. The magnetic field penetrates the air gap and the isolation sleeve 3 to drive the inner magnetic rotor 4 to rotate. The rotor shaft 7 drives the rotor wheel 11 to rotate rapidly. Each sliding vane 14 slides tightly against the inner wall of the pump casing 5 under the action of centrifugal force. A sealed chamber is formed between every two sliding vanes 14. As the rotor wheel 11 rotates, the capacity of the chamber changes continuously. The liquid enters the interior of the inlet flange 10 and the conical tube 17 through the liquid pipe. Due to the continuous entry of the liquid, the liquid enters the cavity between the left isolation plate 25 and the conical tube 17 through the second impurity hole on the hemispherical shell filter screen 19. Next, some liquid will enter the interior of the drainage pipe 21. Due to the inclined top of the drainage pipe 21, the liquid is sprayed obliquely onto the blades of the drive water wheel 24, thereby driving the drive water wheel 24 to rotate rapidly. Then, the liquid falls into the interior of the top pipe 22 through the internal cavity of the drive water wheel 24. Finally, the liquid flows into the interior of the water storage chamber 38. As the liquid increases, the liquid drives the one-way valve 37 to open and enters the cavity between the left isolation plate 25 and the tapered pipe 17 through the one-way valve 37. Then, the liquid enters the interior of the curved pipe 36 through the left drain pipe 33 and the impurity removal component, and then enters the cavity between each pair of sliding vanes 14 through the water inlet pipe 9. As the cavity between each pair of sliding vanes 14 gradually decreases, the sucked liquid is gradually discharged to the outside through the outlet flange 8 port. As liquid is continuously drawn in, the protruding left end of the hemispherical filter screen 19 increases the contact area between impurities and the hemispherical filter screen 19. Impurities larger than the second impurity hole are blocked on the outer left side of the hemispherical filter screen 19. The bevel gear set 27 rotates rapidly with the insertion shaft 29, and the bending plate 30 moves along the outside of the hemispherical filter screen 19. During the rotation, the bending plate 30 can move the impurities adhering to the outside of the hemispherical filter screen 19. At the same time, the liquid can push the impurities along the arc surface of the hemispherical filter screen 19 into the impurity ring 18. Since the impurity tank is provided with the first impurity hole, the liquid inside the impurity tank continues to flow to the right through the first impurity hole, and the impurities can also be temporarily stored in the impurity tank. The impurity tank can filter larger impurities in the liquid, effectively remove iron filings, impurities and other magnetic particles in the liquid, reduce failures caused by wear of internal pump components, and extend the service life of the pump. Since the bending plate 30 is set to continuously clean the outside of the hemispherical filter screen 19, it will not cause a reduction in water volume. When it is necessary to clean the impurity tank, turn off the power, disconnect the pipe, simply turn the port of the inlet flange 10 downwards, insert the cleaning tool into the inside of the inlet flange 10, and clean the impurity tank. The impurities will be discharged downwards along the inlet flange 10. In this way, the hemispherical filter screen 19 can be cleaned without disassembling the magnetic pump, which greatly improves work efficiency and reduces the labor intensity of personnel.

[0028] like Figure 4 , Figure 8 As shown, the impurity removal assembly includes a filter cylinder 41, which is arranged to be open from left to right. A switching shaft 42 is coaxially rotatably connected to the outer wall between the middle isolation plate 31 and the right isolation plate 34. Two control boxes are fixedly installed on the switching shaft 42. A positioning ring 43 is fixedly installed at the other end of each control box. A filter cylinder 41 is fixedly installed on the inner wall of each positioning ring 43. During the rotation of each filter cylinder 41, it can coincide with the left water inlet 32 ​​and the right water inlet 35.

[0029] like Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, an impurity cylinder 44 is fixedly installed on the bottom of the outer shell 16. A conveying auger 45 is rotatably installed inside the impurity cylinder 44. A drive block is fixedly installed on the left end of the conveying auger 45. A discharge port is opened at the lower left side of the impurity cylinder 44. A sealing plug is installed on the discharge port. A discharge port 46 communicating with the left impurity cavity 39 is opened on the left side of the impurity cylinder 44. A discharge port 46 communicating with the right impurity cavity 40 is opened on the right side of the impurity cylinder 44. Impurities inside the left impurity chamber 39 and the right impurity chamber 40 enter the impurity cylinder 44 through the discharge port 46. By opening the sealing plug and rotating the drive block to drive the conveying auger 45, the impurities inside the impurity cylinder 44 can be conveyed to the left and discharged to the outside through the discharge port. This allows for quick discharge of impurities and eliminates the need to disassemble the magnetic pump, reducing maintenance costs.

[0030] like Figure 2 , Figure 4 , Figure 6 As shown, a sprocket assembly 47 is installed on the left end of the middle isolation plate 31. The sprocket assembly 47 includes a first sprocket, a second sprocket, and a chain. The first sprocket is coaxially and rotatably installed on the left end of the middle isolation plate 31. The first sprocket is coaxially and fixedly connected to the switching shaft 42. The second sprocket is rotatably installed on the left side of the middle isolation plate 31. The second sprocket is located in front of the first sprocket. A chain connects the first sprocket and the second sprocket. An adjusting wheel 48 is coaxially and fixedly installed on the left end of the second sprocket. An external hole is opened on the outer shell 16. The adjusting wheel 48 is rotatably installed inside the external hole. The left and right end faces of the adjusting wheel 48 are provided with scales. The adjusting wheel 48 is exposed to the outside. By having the operator rotate the adjusting wheel 48 half a turn and observe the scale, one of the filter cylinders 41 can be perfectly aligned with the left water inlet 32 ​​and the right water inlet 35, thus improving the rotation accuracy of the filter cylinder 41.

[0031] like Figure 6 , Figure 8 , Figure 10As shown, the lower end of the middle isolation plate 31 has a left impurity removal port 49 that runs through both sides. The left water inlet 32 ​​and the left impurity removal port 49 are arranged symmetrically from top to bottom. The lower end of the right isolation plate 34 has a right impurity removal port 50 that runs through both sides.

A first telescopic rod 52 is fixed to each positioning block. The number of first telescopic rods 52 is set as needed. The telescopic end of the left first telescopic rod 52 faces left, and the telescopic end of the right first telescopic rod 52 faces right. The telescopic end and the fixed end of the first telescopic rod 52 will not detach during telescopic sliding. The telescopic ends of the multiple first telescopic rods 52 on the left side are jointly fixed. A left sliding ring is fixedly installed, and a filter screen 53 is fixedly installed on the left sliding ring. A right sliding ring is fixedly installed between the telescopic ends of multiple first telescopic rods 52 on the right side, and a filter screen 53 is fixedly installed on the right sliding ring. The inner diameter of the mesh on the left filter screen 53 is smaller than the inner diameter of the second impurity hole, and the inner diameter of the mesh on the right filter screen 53 is smaller than the inner diameter of the mesh on the left filter screen 53, thereby achieving a multi-stage filtration effect. A suitable existing elastic rubber ring is coaxially fixedly installed on the outer end face of each filter cylinder 41. A compression ring 55 is fixedly installed on the other end face of each elastic rubber ring. The interior of the elastic rubber ring is a hollow structure, and multiple top pressure springs 54 are set inside the elastic rubber ring. One end of the top pressure spring 54 is fixedly connected to the right side wall of the elastic rubber ring, and the other end is fixedly connected to the left end wall of the elastic rubber ring. The number of top pressure springs 54 is set as needed. The other edge of each compression ring 55 is chamfered. When the adjustment wheel 48 is driven by the personnel to rotate, the elastic rubber ring and the top pressure spring 54 can be easily compressed. Under normal conditions, one of the filter cylinders 41 coincides with the left water inlet 32 ​​and the right water inlet 35, and the other filter cylinder 41 coincides with the left impurity removal port 49 and the right impurity removal port 50. Each top pressure spring 54 and elastic rubber ring is in a compressed state, and the compression ring 55 is in contact with the guide ring 51. Liquid enters the left filter screen 53 through the left drain pipe 33. Impurities larger than the diameter of the filter screen 53 will be blocked on the left side of the filter screen 53. Impurities smaller than the mesh diameter will enter the right filter screen 53 with the water flow. At this time, impurities larger than the diameter of the filter screen 53 will be blocked on the left side of the right filter screen 53. The filtered water enters the interior of the curved pipe 36 through the right filter screen 53 for subsequent discharge. Through multi-stage filtration, impurities and particles in the liquid can be fully filtered out, keeping the liquid clean and protecting the normal operation of the magnetic pump.

[0032] like Figure 3 , Figure 8 , Figure 10 , Figure 12 As shown, a cross plate 56 is fixedly installed on each filter screen 53. A left connecting rod 57 is rotatably installed on the right end face of the left cross plate 56, and a right connecting rod 58 is rotatably installed on the left end face of the right cross plate 56. The other end of the left connecting rod 57 is rotatably connected to the rotating block 59, and the other end of the right connecting rod 58 is rotatably connected to the rotating block 59. The number of left connecting rods 57 and right connecting rods 58 can be set as needed. An electrically operated second telescopic rod 60 is fixedly installed inside each control box. Corresponding rod holes are opened on the positioning ring 43 and the filter cylinder 41 on the same side. The telescopic end of the second telescopic rod 60 is installed in the corresponding two rod holes and extends into the interior of the filter cylinder 41. A sealing ring is fixedly installed on the inner wall of each rod hole. The sealing ring is fitted on the telescopic end of the second telescopic rod 60 to prevent liquid leakage into the interior of the control box. The control box contains a controller and a battery. The controller is controlled by an external remote control. The second telescopic rod 60 is connected to the controller via a wire, and the controller is connected to the battery via a wire. The outer end of the outer shell 16 is provided with a charging port and a power switch. The charging port and power switch are connected to the battery via a wire. In actual production, the wires can be arranged reasonably as needed, and the wires will not affect the operation of any component. The electric second telescopic rod 60 can also replace the existing suitable telescopic rod. The telescopic end of the second telescopic rod 60 is fixedly connected to the rotating block 59. A U-shaped vertical rod is fixedly installed on the left end of each left impurity removal port 49. The vertical rod is set on the left end of the middle isolation plate 31. A U-shaped vertical rod is fixedly installed on the right end of the right impurity removal port 50. The vertical rod is set on the right end of the right isolation plate 34. A top impact rod 61 is fixedly installed on the right end of the left vertical rod. The top impact rod 61 is located on the left side of the middle isolation plate 31. A top impact rod 61 is fixedly installed on the left end of the right vertical rod. The top impact rod 61 is located on the right side of the right isolation plate 34. When impurities accumulate on the upper filter screen 53, affecting the liquid output, the power is switched off. The adjusting wheel 48 rotates, causing the sprocket assembly 47 and switching shaft 42 to rotate. The upper filter cartridge 41 moves out from between its corresponding two guide rings 51, and the lower filter cartridge 41 moves out from between its corresponding two guide rings 51. Once each filter cartridge 41 is completely out from between its corresponding two guide rings 51, the elastic rubber ring and the pressure spring 54 cause the left squeeze ring 55 to contact the middle isolation plate 31, and the right squeeze ring 55 to contact the right isolation plate 34. Due to the continuous rotation of the adjusting wheel 48, the clogged filter cartridge 41 moves downwards, and... Furthermore, the chamfer of the squeezing ring 55 contacts and slides against the inclined surface of the guide ring 51, and the elastic rubber ring and the top pressure spring 54 are gradually compressed. The unblocked filter cylinder 41 moves upward, and the chamfer of the squeezing ring 55 contacts and slides against the inclined surface of the guide ring 51. The elastic rubber ring and the top pressure spring 54 are gradually compressed. By observing the scale on the adjusting wheel 48, the unblocked filter cylinder 41 is aligned with the left water inlet 32 ​​and the right water inlet 35, and the blocked filter cylinder 41 is aligned with the left impurity removal port 49 and the right impurity removal port 50. Due to the elastic force of the elastic rubber ring and the top pressure spring 54, each squeezing ring 55 is in close contact with the guide ring 51 to prevent liquid leakage. Next, turn on the power switch. The controller starts the second telescopic rod 60 below to extend downwards quickly. The rotating block 59 moves with the corresponding left connecting rod 57 and right connecting rod 58. The two filter screens 53 move away from each other quickly. Each first telescopic rod 52 extends. The middle of the cross plate 56 on the left side hits the corresponding top rod 61. At this time, the left sliding ring is flush with the left side of the middle isolation plate 31. The middle of the cross plate 56 on the right side hits the corresponding top rod 61. At this time, the right sliding ring is flush with the left side of the middle isolation plate 31. The impurities on the filter screen 53 on the left side fall into the lower discharge port 46. The impurities on the filter screen 53 on the right side fall into the lower discharge port 46. Through the continuous extension and retraction of the second telescopic rod 60, the impurities on each filter screen 53 can be shaken off. The impurities are quickly discharged through the conveying auger 45. After the impurities are cleaned, the second telescopic rod 60 and each component return to their initial state. This magnetic vane pump can clean impurities without disassembling the filter, reducing mechanical friction and wear, extending the service life of the seals and filter. Furthermore, the impact of the cross plate 56 against the top rod 61 can shake impurities off the filter screen 53, making the flow channel of the magnetic pump smoother, reducing resistance, and thus extending the service life of the equipment.
