Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5This utility model provides the following technical solution: A novel circulating water pump with high-efficiency filtration, comprising: a circulating water pump body 1, an inlet 2 on one side of the circulating water pump body 1, a sealing ring 3 fitted onto the open end of the inlet 2, a first bolt 4 threaded through the side wall of the sealing ring 3 and connected to a connecting pipe 5, the inner wall of the connecting pipe 5 fitted onto the other side of the sealing ring 3, the other side surface of the connecting pipe 5 connected to a filter pipe 6, a rod 7 longitudinally inserted into the inner wall of the filter pipe 6, an elastic filter plate 8 connected to the other side surface of the rod 7, and a filter screen box 9 connected to the other side surface of the elastic filter plate 8. The surface abuts against the inner wall of the filter tube 6. The top of the filter tube 6 is provided with a maintenance box 10. The top of the maintenance box 10 is fitted with a sealing frame 11. The top of the sealing frame 11 is fitted with a cover plate 12. The top of the cover plate 12 is longitudinally connected with a third bolt 13. The bottom of the third bolt 13 is threaded through the sealing frame 11 and connected to the top of the maintenance box 10. In this design, the circulating water pump body 1 and the inlet 2 constitute the circulating water pump body. A large number of related components are set in the circulating water pump body. Since they are existing technologies and the core content of this technical solution is not related to them, they will not be described in detail in this technical solution.

[0023] The main model of the circulating water pump in this solution is: NBG100-80;

[0024] In operation: The circulating water pump body creates a certain negative pressure within the pump body through rotating mechanical parts (such as an impeller), thereby extracting fluid. After the fluid is drawn into the pump body, the rotation of the impeller pushes the fluid towards the outlet through centrifugal force. The propelled fluid leaves the pump body through the outlet and enters the inlet of the system pipeline or equipment, thus circulating within the system.

[0025] Preferably, the inlet 2, the sealing ring 3, the first bolt 4, and the connecting pipe 5 form a threaded connection structure.

[0026] In practical use, the sealing ring 3 is fitted onto the open end of the water inlet 2 on one side of the circulating water pump body 1 and connected to the connecting pipe 5 using the first bolt 4.

[0027] Preferably, a set of sealing rings 3 and connecting pipes 5 are provided on both sides of the filter tube 6.

[0028] In practical use, the inlet 2 on one side of the circulating water pump body 1 is fitted with a sealing ring 3 and connected to the connecting pipe 5 by the first bolt 4. Thus, the inlet 2 of the circulating water pump body 1 is connected to the filter pipe 6. At the same time, the sealing ring 3 and the connecting pipe 5 on the other side of the filter pipe 6 are connected to the water inlet system pipe, so that the incoming water flows into the filter pipe 6.

[0029] Preferably, the inner wall of the filter tube 6 has protrusions on both sides, and the top of the protrusions has a slot opened vertically. The shape and size of the insertion rod 7 are adapted to the groove on the top of the protrusion on the inner wall of the filter tube 6.

[0030] In practical use, the insert rods 7 are fixedly inserted into the protrusions on both sides of the filter tube 6, so that the elastic filter plate 8 and the filter screen box 9 are fixed inside the filter tube 6.

[0031] Preferably, the elastic filter plate 8 is a disc shape that matches the shape and size of the inner wall of the filter tube 6, and the filter screen box 9 is provided with elastic filter plates 8 on both sides, and a conical through groove is opened on the side wall of the elastic filter plate 8 at the inlet end of the filter screen box 9.

[0032] In practical use, the insert rod 7, which is inserted into the protrusion on the inner wall of the filter tube 6, can be moved upwards. At the same time, the elastic filter plate 8, which is sleeved in the filter tube 6, can be rolled and bent, so as to facilitate the removal of the filter screen box 9 to clean and replace the impurities collected inside.

[0033] Preferably, the maintenance box 10, the sealing frame 11, the cover plate 12 and the third bolt 13 form a threaded connection structure, and the shape and size of the top opening of the maintenance box 10 are adapted to the filter screen box 9.

[0034] In practical use, the third bolt 13 fixed between the inspection box 10 and the cover plate 12 can be unscrewed. After removing the sealing frame 11 and the cover plate 12, the filter screen box 9 placed in the filter tube 6 can be taken out through the inspection box 10 and cleaned.

[0035] Working principle: Before the circulating water pump body 1 is installed and put into operation, the inlet 2 on one side of the circulating water pump body 1 is fitted with a sealing ring 3 and connected to the connecting pipe 5 by the first bolt 4. Thus, the inlet 2 of the circulating water pump body 1 is connected to the filter pipe 6. At the same time, the sealing ring 3 and the connecting pipe 5 on the other side of the filter pipe 6 are connected to the water inlet system pipe, so that the incoming water flows into the filter pipe 6. The fixed insert rods 7 are inserted into the protrusions on both sides of the filter pipe 6, so that the elastic filter plate 8 and the filter screen box 9 are fixed in the filter pipe 6. When the water flows through the inlet end of the elastic filter plate 8, the impurities inside are flushed with the inverted cone. The water enters the filter box 9 through the inlet and is filtered and intercepted. Then, the water flows through the elastic filter plate 8 on the other side of the filter box 9 and directly into the connecting pipe 5 on the other side of the filter pipe 6. Then, it enters the connected inlet 2 and circulates in the circulating water pump body 1. After long-term operation, the third bolt 13 fixed between the maintenance box 10 and the cover plate 12 can be unscrewed. After removing the sealing frame 11 and the cover plate 12, the insert rod 7 inserted into the protrusion on the inner wall of the filter pipe 6 can be moved upward. At the same time, the elastic filter plate 8 sleeved in the filter pipe 6 can be rolled and bent, so as to facilitate the removal of the filter box 9 for cleaning and replacement of the impurities collected inside.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
