Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, specifically a submersible pump with dual filtration function. Background Technology

[0002] Submersible pumps are water lifting devices that directly connect a motor and a water pump and operate submerged in liquid. They lift liquid energy through the centrifugal force of the impeller and are widely used in groundwater extraction, farmland irrigation, industrial drainage and other fields.

[0003] In order to prevent debris from entering the interior of the submersible pump during use, a filter screen is usually installed at the water inlet of the existing submersible pump. This filter screen is used to block debris from entering and has a good protective effect. However, this filtration method is a single-layer filter, so its filtration effect is not significant and it is not convenient to clean the filter screen.

[0004] Therefore, this invention provides a submersible pump with dual filtration function to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a submersible pump with dual filtration function, including a submersible pump body 1. The lower end of the submersible pump body 1 has a water inlet 2, through which water flows into the interior of the submersible pump body 1 to ensure the normal operation of the submersible pump. The lower end of the submersible pump body 1 is spirally connected to a filter tube 3, and the lower end of the filter tube 3 has multiple arc-shaped grooves. While facilitating the flow of water into the interior of the submersible pump body 1, it can also prevent larger debris in the water from entering the interior of the submersible pump body 1, thus providing a good protective effect. When there is a certain amount of debris inside the filter tube 3, it is only necessary to rotate the filter tube 3 based on the submersible pump body 1 to remove the filter tube 3 from the submersible pump body 1 for cleaning, which is very convenient.

[0027] A closed ring 7 is fixedly connected inside the filter tube 3. An inner rotating ring 8 is rotatably connected to the inner wall of the closed ring 7. A filter screen 9 is installed inside the inner rotating ring 8. The filter screen 9 can filter out smaller impurities and debris in the water, preventing smaller debris from entering the submersible pump body 1. Through double filtration, the filtration effect is improved, and a further protective effect is achieved.

[0028] The filter tube 3 is internally connected to an outer rotating ring 6. The upper end of the outer rotating ring 6 is fixedly connected to a U-shaped frame 13. A rotating column 4 is passed through and fixedly connected to the U-shaped frame 13. The upper end of the rotating column 4 is fixedly connected to a drive fan blade 5. When water flows into the submersible pump body 1, it will drive the drive fan blade 5 to rotate. When the drive fan blade 5 rotates, it can drive the rotating column 4 below to rotate synchronously. At this time, the outer rotating ring 6 can be driven to rotate based on the filter tube 3 through the U-shaped frame 13, and the rotation direction of the outer rotating ring 6 is consistent with the water flow direction.

[0029] Multiple first teeth 10 are fixedly connected to the inner wall of the outer rotating ring 6, and multiple second teeth 11 are fixedly connected to the outer wall of the inner rotating ring 8. A drive gear 12 is rotatably connected to the upper end of the closed ring 7. The drive gear 12 can rotate based on the closed ring 7 itself. The drive gear 12 is located between the outer rotating ring 6 and the inner rotating ring 8, and is in a meshing state with the first teeth 10 and the second teeth 11. When the outer rotating ring 6 rotates under the action of water flow, it can drive the first teeth 10 on its inner wall to rotate, which can drive the drive gear 12 meshing with it to rotate. When the drive gear 12 rotates, it can drive the inner rotating ring 8 to rotate through the second teeth 11. The rotation direction of the inner rotating ring 8 is opposite to the water flow direction. The filter screen 9 follows the rotation of the inner rotating ring 8, which can improve the filtration effect of impurities.

[0030] A connecting ring 14 is fixedly connected to the outer wall of the rotating column 4, and a scraper 15 is fixedly connected to the outer wall of the connecting ring 14. Both the connecting ring 14 and the scraper 15 are located outside the filter tube 3. The scraper 15 is in full contact with the lower end surface of the filter tube 3. When the rotating column 4 rotates under the action of the driving fan blade 5, the scraper 15 can be driven to rotate synchronously through the connecting ring 14. The rotation of the scraper 15 can clean the lower end surface of the filter tube 3, preventing large debris in the water from adhering to the lower end surface of the filter tube 3 and causing blockage at the inlet 2, thus ensuring the normal use of the submersible pump.

[0031] The working principle of this utility model is as follows: During the use of the submersible pump, water flow can enter the interior of the submersible pump body 1 through the filter pipe 3 and the inlet 2, ensuring the normal operation of the submersible pump. When the water flows through, it will drive the drive fan blade 5 to rotate, thereby driving the rotating column 4 to rotate synchronously. When the rotating column 4 rotates, it can drive the outer rotating ring 6 to rotate through the U-shaped frame 13. At this time, it can drive the drive gear 12 to rotate through the first tooth 10. When the drive gear 12 rotates, it can drive the inner rotating ring 8 on the closed ring 7 to rotate through the second tooth 11. The filter screen 9 on the inner rotating ring 8 rotates with it, and its rotation direction is opposite to the water flow direction. The rotatable filter screen 9 can filter impurities more significantly, improving the filtration effect of the submersible pump body 1. When the rotating column 4 rotates, it will also drive the connecting ring 14 and the scraper 15 to rotate synchronously. When the scraper 15 rotates, it can clean the lower surface of the filter pipe 3, preventing large impurities from clogging the filter pipe 3 and ensuring the normal use of the submersible pump.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
