Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump with a filtering structure. Background Technique

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspension emulsions, and liquid metals, etc. According to different working principles, it can be divided into types such as positive displacement water pumps and vane pumps. A positive displacement pump uses the change in the volume of its working chamber to transfer energy; however, since the water inlet of the water pump is directly connected to the water pipe, during the pumping process, impurities in the water are likely to block the water inlet of the water pump, which will further affect the water absorption flow rate of the water pump, and even cause damage to the water pump, making the water pump unable to continue working and affecting the efficiency of the water pump's water lifting work.

[0003] When the existing water pump filtering structure is in use, after impurities are filtered by the filter mesh plate, they will continuously adhere to the filter mesh plate, causing blockage to the filter mesh plate, thereby affecting the flow rate of water and the normal use of the water pump. For this reason, we propose a water pump with a filtering structure. Content of the Utility Model

A plug block is tightly inserted into the chip discharge port. A cover plate is fixedly installed at the bottom end of the plug block. The cover plate is clamped in the cover groove. The cover plate is fixedly installed in the cover groove through bolt two.

[0007] Preferably, a pull ring is fixedly installed at the bottom end of the cover plate. By setting the pull ring, it is convenient for personnel to pull the cover plate downward through the pull ring, thus facilitating the operation of personnel.

[0008] Preferably, the shape of the annular guide plate is "ㄥ", and a funnel shape is formed between the annular guide plate and the annular guide table, which can enable impurities to pass through the gap between the annular guide plate and the annular guide table and be stored between the annular guide plate and the edge of the arched filter screen plate, and it is not easy to run out from the gap again.

[0009] Preferably, the number of the clamping blocks, the clamping grooves and the first bolts is four.

[0010] Preferably, the material of the blocking block is corrosion-resistant rubber, the cover plate is adapted to the cover groove, and the number of the second bolts is two.

In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] As Figures 1-5 shown, the present utility model provides a technical solution: a water pump with a filtering structure, including a water pump 1, a suction pipe 2 is connected in communication with the input end of the water pump 1, a discharge pipe 3 is connected in communication with the output end of the water pump 1, the suction pipe 2 is fixedly connected with a filter pipe 4 through bolts, and a filter mechanism 5 is arranged inside the filter pipe 4;

[0025] The filtering mechanism 5 includes an arched filter screen plate 501, a first bolt 509 and a second bolt 510. The arched filter screen plate 501 is snapped into the filter pipe 4. A clamping block 508 is fixedly installed on the outer wall of the arched filter screen plate 501. A clamping groove 511 is formed in the inner wall of the filter pipe 4. The clamping block 508 is clamped in the clamping groove 511. The clamping block 508 is fixedly installed on the inner wall of the clamping groove 511 through the first bolt 509. An annular guide plate 502 is fixedly installed on the inner wall of the filter pipe 4. An annular guide platform 503 is fixedly installed on the outer wall of the arched filter screen plate 501. A cover groove 507 is formed at the bottom end of the outer wall of the filter pipe 4. A chip discharge port 505 is formed at the top end of the inner wall of the cover groove 507. A plug block 504 is closely inserted into the chip discharge port 505. A cover plate 506 is fixedly installed at the bottom end of the plug block 504. The cover plate 506 is clamped in the cover groove 507. The cover plate 506 is fixedly installed in the cover groove 507 through the second bolt 510.

[0026] Specifically in the above technical solution, when the water pump 1 with a filtering structure is in use, the filter pipe 4 is connected to one end of the water suction pipe 2 through bolts. The water pump 1 is started. When the water flow passes through the filter pipe 4, the impurities in the water flow will remain on one side of the arched filter screen plate 501 under the filtration of the arched filter screen plate 501. Due to the shape of the arched filter screen plate 501, the impurities will move towards the edge of the arched filter screen plate 501 under the impact of the water flow, and finally the impurities will pass through the gap between the annular guide plate 502 and the annular guide platform 503 and be stored between the annular guide plate 502 and the edge of the arched filter screen plate 501, and it is not easy to run out from the gap again. When the water pump 1 stops running, the second bolt 510 can be unscrewed, and then the cover plate 506 is pulled downward, so that the cover plate 506 drives the plug block 504 to disengage from the chip discharge port 505, opening the chip discharge port 505. At this time, the impurities between the annular guide plate 502 and the edge of the arched filter screen plate 501 will be discharged through the chip discharge port 505 to clean the impurities and ensure the normal use effect of the filter pipe 4. Through the combined cooperation of the arched filter screen plate 501, the annular guide plate 502 and the annular guide platform 503, it is possible to prevent impurities from continuously adhering to the arched filter screen plate 501 and causing blockage of the arched filter screen plate 501, solving the problem that in the existing filtering structure of the water pump 1, after the impurities are filtered by the filter screen plate, they will continuously adhere to the filter screen plate, causing blockage of the filter screen plate, thereby affecting the flow rate of the water flow and the normal use of the water pump 1; by providing the chip discharge port 505, the plug block 504 and the cover plate 506, it is convenient for personnel to clean the impurities in the filter pipe 4 in time, ensuring the normal use effect of the filter pipe 4, with a simple structure and strong practicability.

[0027] Further, a pull ring 6 is fixedly installed at the bottom end of the cover plate 506;

[0028] Among them, by providing the pull ring 6, it is convenient for personnel to pull the cover plate 506 downward through the pull ring 6, thus facilitating the operation of personnel.

[0029] Further, the shape of the annular guide plate 502 is "ㄥ", and a funnel shape is formed between the annular guide plate 502 and the annular guide table 503, which can allow impurities to pass through the gap between the annular guide plate 502 and the annular guide table 503 and be stored between the annular guide plate 502 and the edge of the arched filter screen plate 501, and it is not easy to run out from the gap again.

[0030] Further, the number of the clamping blocks 508, the clamping grooves 511, and the first bolts 509 is four.

[0031] Further, the material of the plug block 504 is corrosion-resistant rubber, the cover plate 506 is adapted to the cover groove 507, and the number of the second bolts 510 is two;

[0032] Among them, by using corrosion-resistant rubber for the material of the plug block 504, the sealing performance between the plug block 504 and the chip discharge port 505 can be improved.

[0033] Further, the clamping blocks 508 are adapted to the clamping grooves 511;

[0034] Among them, by providing the clamping blocks 508, the arched filter screen plate 501 can be installed in a limited position.
