Description

Technical Field

[0001] This utility model relates to the field of axial flow pump technology, specifically to an axial flow pump that facilitates impeller cleaning. Background Technology

[0002] Axial flow pumps are pumps that use the force generated by the blades of a rotating impeller to transport liquid along the axial direction. There are several types, including vertical, horizontal, inclined, and through-flow pumps. Axial flow pumps are common household items. They can use the rotation of the impeller to bring water from a low place to a high place, making them convenient for people to use.

[0003] In existing axial flow pumps, the impeller surface tends to accumulate a large amount of water impurities after long-term use, which affects the impeller's performance. However, it is inconvenient to disassemble the impeller for cleaning in existing axial flow pumps, and the impeller's performance deteriorates more significantly with prolonged use, affecting the working efficiency of the axial flow pump. To address the above problems, the inventors propose an axial flow pump with an impeller that is easy to clean. Utility Model Content

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.

[0019] Example: Figure 1-3 As shown, this utility model provides a technical solution: an axial flow pump that facilitates impeller cleaning, comprising a pump body 1, a pump motor 11 fixedly mounted at one end of the pump body 1, a drive end of the pump motor 11 fixedly connected to a shaft 12, an impeller body 13 connected to one end of the shaft 12, symmetrically distributed horizontal blocks 14 fixedly mounted at one end of the impeller body 13, a vertical block 15 slidably inserted into one end of the horizontal block 14, a movably inserted end of the vertical block 15 into the inner side of the shaft 12, a connecting block 16 fixedly connected to one end of the vertical block 15, and a lead screw 17 rotatably mounted at one end of the horizontal block 14. One end of the screw is threaded onto the outside of the lead screw 17. One end of the cross block 14 is fixedly installed with a guide rod 18. One end of the guide rod 18 is fixedly connected with a limit ring 19. One end of the connecting block 16 is slidably sleeved on the outside of the guide rod 18. The outer side of the shaft 12 is threaded with symmetrically distributed first bolts 20. One end of the first bolt 20 is threadedly connected to the vertical block 15. One end of the pump body 1 has an annular groove 21. A sealing plate 22 is slidably installed on the inner side of the annular groove 21. One end of the sealing plate 22 is threaded with a second bolt 23. One end of the second bolt 23 is threadedly connected to the pump body 1.

[0020] By adopting the above technical solution, the part of the pump body 1 that comes into contact with water is made of enamel material to achieve the purpose of corrosion prevention.

[0021] A filter screen 24 is movably mounted on one end of the pump body 1. A symmetrically distributed fixing block 25 is fixedly installed on the inner side of the pump body 1. A connecting post 26 is fixedly installed on one end of the fixing block 25. A spring 27 is fixedly sleeved on the outer side of the connecting post 26. One end of the spring 27 is fixedly connected to the filter screen 24. A handle 28 is fixedly installed on one end of the filter screen 24.

[0022] By adopting the above technical solution, the filter screen 24 can be easily pulled out of the pump body 1 by pulling the handle 28. The spring 27 cooperates with the filter screen 24 to be in a stretched state. After cleaning the pulled-out filter screen 24, it can be released. The filter screen 24 is reset back into the pump body 1 by the action of the spring 27 and the connecting column 26. The structure is ingenious and easy to use.

[0023] A limiting plate 29 is fixedly installed at the top of the vertical block 15, and one end of the limiting plate 29 is attached to the horizontal block 14.

[0024] By adopting the above technical solution, the vertical block 15 is limited by setting the limiting plate 29.

[0025] The outer side of the lead screw 17 is fixedly fitted with symmetrically distributed limiting rings 30, and the opposite end of the limiting ring 30 is in contact with the cross block 14.

[0026] By adopting the above technical solution, the lead screw 17 is limited by setting a limit ring 30.

[0027] A T-shaped block 31 is fixedly installed at the top of the lead screw 17.

[0028] By adopting the above technical solution, the T-shaped block 31 is set to facilitate the rotation of the adjusting screw 17.

[0029] The outer fixing clip of the annular groove 21 is provided with a leak-proof seal 32, one end of which is attached to the sealing plate 22.

[0030] By adopting the above technical solution, water leakage is prevented and the sealing performance is improved by setting the anti-leakage seal 32 and the gap between the sealing plate 22 and the annular groove 21.

[0031] Working principle: First, when it is necessary to clean the impeller body 13, manually remove the second bolt 23, then slide the sealing plate 22 into the annular groove 21 for storage, then remove the first bolt 20, and then rotate the T-block 31. The rotation of the T-block 31 drives the lead screw 17 to rotate. The limiting ring 30 limits the rotation of the lead screw 17. The rotation of the lead screw 17 drives the connecting block 16 to move. The connecting block 16 slides on the guide rod 18 to guide itself, thereby the connecting block 16 drives the vertical block 15 to move. The vertical block 15 slides on the horizontal block 14 and is pulled out from the shaft 12. Then pull the handle 28 to pull out the filter screen 24 and remove the disassembled filter screen. The impeller body 13 can be removed for cleaning, thus achieving disassembly of the impeller body 13 and facilitating cleaning, ensuring that the performance of the impeller body 13 is not affected or reduced. The filtration of water flow by the filter screen 24 also reduces the degree of contamination of the impeller body 13. By pulling the handle 28, the filter screen 24 can be easily pulled out from the pump body 1. The spring 27 cooperates with the filter screen 24 to be in a stretched state. After cleaning the pulled-out filter screen 24, it can be released. The filter screen 24 is reset back into the pump body 1 by the action of the spring 27 and the connecting column 26. The structure is ingenious and easy to use.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
