Description

Technical Field

[0001] This utility model relates to the field of cyclone pump technology, specifically an anti-clogging counter-rotating axial flow pump. Background Technology

[0002] Axial flow pumps are pumps that use the force exerted by the blades of a rotating impeller on the liquid to transport it along the axial direction. They come in several types, including vertical, horizontal, inclined, and through-flow pumps. Axial flow pumps are commonly used in paddy field irrigation, urban sewage treatment, and water conservancy projects. During operation, the filter plate at the bottom flared inlet of an axial flow pump often becomes clogged with debris such as leaves, weeds, and waste paper, reducing its efficiency.

[0003] According to Chinese Patent CN 222823447 U, an anti-clogging axial flow pump is disclosed, including an axial flow pump and a wall. The outer wall of the axial flow pump is provided with an installation plate connected to the wall. An installation box is provided on the outer side of the bottom of the axial flow pump. In this solution, an electric telescopic rod pushes a baffle to move and block the filter plate, thereby removing the debris attached to the bottom of the filter plate. The baffle corresponding to the non-clogging filter plate moves and no longer blocks the filter plate, thus ensuring that one filter plate can be used normally, thereby avoiding clogging of the axial flow pump.

[0004] However, in the above solution, the push plate cannot continuously clean the surface of the filter plate, resulting in an unstable flow rate of the filter plate. Furthermore, the cover plate is fixed to the mounting plate by bolts, making it inconvenient to remove the filter plate from the mounting box for cleaning and replacement. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging counter-rotating axial flow pump to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging counter-rotating axial flow pump, comprising a pump body, a housing provided on the outer side of the pump body, a fixed plate fixedly connected to the outer side of the pump body, a filter cylinder fixedly connected to the bottom of the pump body, a cover plate provided on the fixed plate, the cover plate fixedly connected to the top end of a connecting rod, the bottom end of the connecting rod fixedly connected to a filter plate, the filter cylinder rotatably connected to the outer side of a rotating shaft, a fan blade fixedly connected to the outer side of the rotating shaft, the upper surface of the fixed plate rotatably connected to the connecting shaft, and a clamping plate fixedly connected to the top end of the connecting shaft.

[0007] Preferably, a circular through hole for placing the filter cartridge is provided on the upper surface of the housing, and the housing is bolted to the fixing plate for fixation.

[0008] Preferably, a clearance hole is provided on the upper surface of the fixing plate, the outer diameter of the filter plate and the baffle are both smaller than the clearance hole, and the cover plate is attached to the upper surface of the card plate.

[0009] Preferably, the bottom surface of the card plate is provided with a magnetic absorbing sheet, and the card plate is attracted to the upper surface of the cover plate through the magnetic absorbing sheet.

[0010] Preferably, the bottom surface of the filter cylinder has a placement hole, which is engaged with the filter plate; the upper surface of the filter cylinder has a mating hole; the outer side of the connecting rod is fixedly connected to the baffle; the baffle is adapted to the mating hole; and a sealing ring is provided on the baffle.

[0011] Preferably, the bottom end of the rotating shaft is fixedly connected to the scraper, and the scraper is in contact with the bottom surface of the filter plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model filters impurities in water through a filter screen, preventing weeds, dead branches and leaves in the water from causing blockage in the cyclone pump. The rotation of the impeller inside the pump body causes water to flow, which in turn drives the fan blades and the rotating shaft to rotate, so that the scraper cleans the bottom surface of the filter plate, preventing impurities from adhering to the bottom surface of the filter plate and affecting the fluid flow rate, thus ensuring a stable water pumping effect.

[0014] 2. This utility model also features a magnetic suction plate on the bottom surface of the card plate. By rotating the connecting shaft, the card plate can be separated from the cover plate surface, and the filter plate can be pulled out of the filter cylinder through the handle on the cover plate surface. This facilitates cleaning of the filter plate, ensures the filtration effect of the filter plate, and further reduces the clogging of the cyclone pump. The structure is simple and the operation is convenient. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides a technical solution: an anti-clogging counter-rotating axial flow pump, including a pump body 1, a housing 2 disposed on the outer side of the pump body 1, and a fixing plate 3 welded and fixed to the outer side of the pump body 1. A circular through hole is formed on the upper surface of the housing 2 for placing a filter cartridge 4, allowing the filter cartridge 4 to pass through the circular through hole and be placed inside the housing. The inside of the housing is filled with the fluid being transported. The housing 2 is bolted and fixed to the fixing plate 3. A sealing gasket is provided at the connection between the housing 2 and the fixing plate 3 to improve the sealing performance of the connection and reduce vibration during pump body 1 operation.

[0023] A clearance hole is provided on the upper surface of the fixing plate 3. The outer diameters of both the filter plate 7 and the baffle 12 are smaller than the clearance hole, which facilitates the separation of the filter plate 7 and the baffle 12 from the clearance hole, enabling easy disassembly of the filter plate 7. The upper surface of the fixing plate 3 is fitted to the cover plate 5, and a sealing gasket is provided on the bottom surface of the cover plate 5 to improve the sealing performance at the connection.

[0024] The upper surface of the fixed plate 3 is rotatably connected to the connecting shaft 13. A damping pad is provided at the connection between the fixed plate 3 and the connecting shaft 13 to prevent the connecting shaft 13 from rotating due to vibration of the pump body 1. At the same time, the top of the connecting shaft 13 is fixedly connected to the clamping plate 14. The cover plate 5 is attached to the upper surface of the clamping plate 14. A magnetic suction plate is provided on the bottom surface of the clamping plate 14. The clamping plate 14 is attracted to the upper surface of the cover plate 5 through the magnetic suction plate, preventing the cover plate 5 and the filter plate 7 from shaking up and down, which would cause a gap between the connecting rod 6 and the placement hole 8, allowing impurities to enter. The cover plate 5 is made of magnetic metal, so the rotation of the clamping plate 14 will not be hindered by the magnetic force of the magnetic suction plate. The upper surface of the cover plate 5 is welded and fixed to the handle. By pulling the handle, the filter plate 7 can be pulled out from the inside of the filter cylinder 4, realizing convenient replacement of the connecting rod 6.

[0025] The bottom of the pump body 1 is fixedly connected to the filter cylinder 4, the bottom of the connecting rod 6 is fixedly connected to the filter plate 7, and the cover plate 5 is fixedly connected to the top of the connecting rod 6.

[0026] A placement hole 8 is provided on the bottom surface of the filter cylinder 4, which engages with the filter plate 7. The filter plate 7 is evenly distributed on the bottom surface of the filter cylinder 4, thereby expanding the fluid inlet and facilitating the filter plate 7 to block impurities. The filter cylinder 4 is rotatably connected to the outside of the rotating shaft 9 via a sealed bearing. The outside of the rotating shaft 9 is fixedly connected to the fan blade 10. The flow of fluid will drive the rotation of the rotating shaft 9 and the fan blade 10, thereby causing the scraper 11 to rotate and clean the bottom surface of the filter plate 7, preventing the filter plate 7 from reducing its filtration effect due to impurities.

[0027] A mating hole is formed on the upper surface of the filter cartridge 4. The outer side of the connecting rod 6 is fixedly connected to the baffle 12. The baffle 12 is adapted to the mating hole. The baffle 12 blocks the mating hole to prevent liquid from flowing out from the gap of the baffle 12 after the fluid enters the filter cartridge 4, which would affect the pumping efficiency. A sealing ring is provided on the baffle 12 to further enhance the sealing effect of the baffle 12.

[0028] The bottom end of the rotating shaft 9 is fixedly connected to the scraper 11, and the scraper 11 is in contact with the bottom surface of the filter plate 7.

[0029] Working principle: During use, the fixing plate 3 is connected and fixed to the surface of the housing 2 with bolts, thereby fixing the pump body 1. The rotation of the impeller inside the pump body 1 drives the fluid to enter the pump body 1 from the bottom of the filter cylinder 4 for pumping. The filter plate 7 filters impurities in the fluid to prevent blockage inside the pump body 1. When the fluid flows through the filter cylinder 4, it drives the rotating shaft 9 and the fan blade 10 to rotate, which in turn causes the scraper 11 to rotate, thereby scraping and cleaning the impurities attached to the bottom surface of the filter plate 7, preventing the accumulation of impurities from reducing the filtration efficiency.

[0030] When the filter plate 7 needs cleaning after a long period of filtration, rotate the connecting shaft 13 to disengage the clamping plate 14 from the surface of the cover plate 5. Then, use the handle on the upper surface of the cover plate 5 to pull the filter plate 7 out of the filter cylinder 4 to clean it. This reduces the difficulty of disassembling, replacing, and cleaning the filter plate 7 and improves the actual use effect.
