Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a foreign matter filtration device for water pumps. Background Technology

[0002] A water pump is a machine used to transport or pressurize liquids. It is mainly used to transport water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. When transporting liquids containing impurities, water pumps use filtration devices to filter the impurities in the liquid before it enters the pump, ensuring the normal operation of the pump. However, modern filtration devices, after intercepting and filtering impurities in the liquid, make it difficult for operators to quickly process the impurities accumulated in the filtration device, leading to clogging of the filtration device and affecting the normal operation of the water pump. Utility Model Content

[0003] This utility model discloses a foreign matter filtering device for water pumps, which solves the problem of inconvenience for workers to handle impurities accumulated in the filtering device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A foreign matter filtration device for a water pump includes a first mounting pipe, an inlet end of which is connected to a folded pipe, a fixed pipe fixed to the other end of the folded pipe, a first fixing ring fixed to the other end of the fixed pipe, a second mounting pipe located on the side of the first fixing ring away from the fixed pipe, and a second fixing ring fixed to the drain end of the second mounting pipe by bolts. A first filter cylinder with an open water-facing end is detachably connected inside the fixed pipe, and a second filter cylinder with an arc-shaped water-facing surface is threadedly connected to the open end of the first filter cylinder. The diameter of the filter holes on the second filter cylinder is larger than the diameter of the filter holes on the first filter cylinder, and a connecting ring with an outer ring surface in contact with the inner wall of the fixed pipe is fixed on the outer wall of the first filter cylinder.

[0005] Compared with the prior art, the present invention has the following beneficial effects: The drain end of the first mounting pipe is connected to the inlet end of the water pump. The first and second fixing rings are then fixed together with bolts. When water enters the fixed pipe through the second mounting pipe, the second filter cartridge filters larger impurities. The second filter cartridge has an arc-shaped water-facing surface to prevent impurities from adhering to it. When water passes through the filter holes on the second filter cartridge and enters the first filter cartridge, smaller impurities are collected there. To clean the impurities in the first filter cartridge, the first and second fixing rings are separated, the folded tube is compressed to move the fixed tube away from the second mounting pipe, and the second filter cartridge is removed from the first filter cartridge. The folded tube is then bent so that the inlet end of the fixed tube faces downwards, facilitating the removal of impurities accumulated in the fixed pipe and the first filter cartridge. This invention allows for quick separation of the first and second fixing rings and removal of accumulated impurities, simplifying the operation, improving cleaning efficiency, and ensuring the normal operation of the water pump.

[0008] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0009] like Figure 1 and Figure 2As shown, this utility model provides a foreign matter filtration device for a water pump, including a first mounting pipe 1, a folded pipe 2 connected to the water inlet end of the first mounting pipe 1, a fixed pipe 21 fixed to the other end of the folded pipe 2, a first fixing ring 22 fixed to the other end of the fixed pipe 21, a second mounting pipe 3 provided on the side of the first fixing ring 22 away from the fixed pipe 21, a second fixing ring 31 fixed to the drain end of the second mounting pipe 3 by bolts and connected to the first fixing ring 22; a first filter cylinder 4 with an open water-facing end is detachably connected inside the fixed pipe 21, a second filter cylinder 41 with an arc-shaped water-facing surface is threaded to the open end of the first filter cylinder 4, the diameter of the filter holes on the second filter cylinder 41 is larger than the diameter of the filter holes on the first filter cylinder 4, and a connecting ring 5 with an outer ring surface in contact with the inner wall of the fixed pipe 21 is fixed on the outer wall of the first filter cylinder 4. The drain end of the first mounting pipe 1 is connected to the inlet end of the water pump. The open end of the first filter cylinder 4 is located inside the second mounting pipe 3. The first fixing ring 22 and the second fixing ring 31 are fixed together with bolts. When water enters the fixing pipe 21 through the second mounting pipe 3, the second filter cylinder 41 first filters out larger impurities. The water-facing surface of the second filter cylinder 41 is arc-shaped to prevent impurities from adhering to the water-facing surface of the second filter cylinder 41. The impurities move with the water flow to the gap between the outer wall of the first filter cylinder 4 and the inner wall of the second mounting pipe 3. 5 can block impurities; when water passes through the filter holes on the second filter cylinder 41 and enters the first filter cylinder 4, smaller impurities in the water are collected in the first filter cylinder 4. When it is necessary to clean the impurities in the first filter cylinder 4, the first fixing ring 22 and the second fixing ring 31 are separated, the folded tube 2 is compressed so that the fixing tube 21 is away from the second mounting tube 3, then the second filter cylinder 41 is removed from the first filter cylinder 4, and the folded tube 2 is bent so that the water inlet end of the fixing tube 21 is facing down, so that the impurities accumulated in the fixing tube 21 and the first filter cylinder 4 can be poured out.

[0010] like Figure 1 and Figure 2As shown, a connecting rod 42 located inside the first filter cylinder 4 is fixed to the inner side of the second filter cylinder 41. A third filter cylinder 43 is fixed to the other end of the connecting rod 42. The end of the third filter cylinder 43 away from the connecting rod 42 is open and has a ring 44 fixed thereon. The outer ring surface of the ring 44 is in contact with the inner wall of the first filter cylinder 4. A through hole with the same diameter as the filter hole on the first filter cylinder 4 is formed on the ring 44. The diameter of the filter hole on the third filter cylinder 43 is larger than the diameter of the filter hole on the first filter cylinder 4 but smaller than the diameter of the filter hole on the second filter cylinder 41. The third filter cylinder 43 is funnel-shaped and the water-facing side is arc-shaped. When smaller impurities enter the first filter cylinder 4 with the water, the third filter cylinder 43 can also block medium-sized impurities. The water-facing surface of the third filter cylinder 43 is arc-shaped, which can prevent impurities from accumulating on the water-facing surface of the third filter cylinder 43, allowing the impurities to move to the gap between the outer wall of the third filter cylinder 43 and the inner wall of the first filter cylinder 4, ensuring that the water can pass smoothly through the filter holes on the water-facing surface of the third filter cylinder 43. At the same time, the funnel-shaped design of the third filter cylinder 43 can effectively increase the storage space for impurities, so as to better collect the impurities in the gap between the outer wall of the third filter cylinder 43 and the inner wall of the first filter cylinder 4. The space between the end of the first filter cylinder 4 away from the open end and the ring 44 can filter and collect smaller impurities in the water.

[0011] like Figure 1 and Figure 2 As shown, a fixing beam 6 is fixed to the inner wall of the fixing tube 21, and a screw 61 is fixed to the fixing beam 6. A screw hole adapted to the screw 61 is provided on the first filter cylinder 4. A cover 7 that covers the folded tube 2 is fixed to the first fixing ring 22. A sealing ring 23 is fixed to the side of the first fixing ring 22 near the second mounting tube 3, and an annular groove adapted to the sealing ring 23 is provided on the second fixing ring 31. After separating the first filter cylinder 4 from the screw 61, the first filter cylinder 4 can be removed from the fixing tube 21 for inspection and maintenance; the cover 7 can cover the folded tube 2, effectively protecting it; the sealing ring 23, in conjunction with the annular groove, can increase the tightness of the connection between the first fixing ring 22 and the second fixing ring 31.

[0012] like Figure 1 As shown, a filter plate 8 is fixed inside the first mounting tube 1, close to the folded tube 2. The diameter of the filter holes on the filter plate 8 is smaller than the diameter of the filter holes on the first filter cylinder 4. The filter plate 8 can block finer impurities in the water. After the first filter cylinder 4 is removed from the fixed tube 21, the folded tube 2 can be bent to pour out the impurities blocked by the filter plate 8.

[0013] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
