[0003] The prior art (publication number: CN 219220737 U) discloses a horizontal centrifugal pump, which relates to the technical field of centrifugal pumps, and comprises a base, a centrifugal pump body is fixedly provided on the top of the base, a cylinder sleeve is fixedly provided on the top of the base, a spring is fixedly connected to the top of the inner cavity of the cylinder sleeve, a rubber damping rubber block is provided in the inner cavity of the spring, a slider is fixedly connected to the other end of the spring, a connecting column is fixedly provided on the top of the slider, and a universal wheel is fixedly provided on the bottom of the connecting column.

[0004] Although the above patent can move the centrifugal pump through the universal wheel, so as to facilitate the staff to carry the centrifugal pump and reduce the burden on the staff, it has the following disadvantages. When in use, if the liquid contains impurities, the impurities are easy to rub against the inner wall and internal parts of the pump body, thereby causing damage to the inside of the pump body and the parts inside the pump body, reducing the stability of the centrifugal pump, shortening its service life, and increasing the cost of use. Further improvement is needed. For this reason, we propose a centrifugal pump with high operating stability. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. Impurities in the liquid can be filtered by setting the filter component. When in use, the liquid enters the filter box through the water pipe, the liquid enters the hollow cylinder through the sieve hole, and then enters the impeller assembly through the connecting pipe. The setting of the sieve hole can prevent impurities in the liquid from entering the hollow cylinder, avoiding the impurities from rubbing against the inner wall and internal parts of the impeller assembly to cause damage to the inside of the impeller assembly and internal parts, improving the stability of the centrifugal pump when running at high speed, increasing its service life, and reducing the cost of later maintenance;

No manual cleaning is required, which reduces the operating steps of the workers. At the same time, the second motor is controlled to drive the hollow cylinder to rotate, so that the high-pressure nozzle cleans other surfaces of the hollow cylinder to improve the cleaning effect.

[0026] In order to improve the stability of the centrifugal pump when it runs at high speed, increase its service life, and reduce the cost of subsequent maintenance, the impurities in the liquid are filtered through the filter component 12. The specific structure is as follows: the filter component 12 includes a hollow cylinder 121, and the hollow cylinder 121 is arranged on the left inner wall of the filter box 7. The left end of the hollow cylinder 121 is in active contact with the left inner wall of the filter box 7. A plurality of sieve holes 122 are provided on the outer surface of the hollow cylinder 121. A guide ring 123 is fixedly sleeved on the right part of the outer cylindrical surface of the hollow cylinder 121. The right end of the hollow cylinder 121 is movably penetrated to the right side of the baffle 13. The setting of the sieve holes 122 can prevent impurities in the liquid from entering the hollow cylinder 121, thereby preventing the impurities from rubbing against the inner wall and internal parts of the impeller assembly 3, causing damage to the inside and internal parts of the impeller assembly 3.

[0027] The guide ring 123 is movably sleeved in the baffle 13 , and is used to support the hollow cylinder 121 to rotate in the baffle 13 .

[0028] After the filter component 12 has been used for a certain period of time, more impurities will adhere to its surface, affecting the normal flow of the liquid. The surface of the filter component 12 can be cleaned by the cleaning component 11, ensuring that the liquid can pass through the inside of the sieve hole 122 normally, ensuring the normal operation of the centrifugal pump, and no manual cleaning is required, which reduces the operating steps of the workers.

The setting of the sieve hole 122 can prevent impurities in the liquid from entering the hollow cylinder 121. After the filter component 12 has filtered for a certain period of time, the valve pipe 10 is opened, and the pump body 111 is controlled to transport water to the hollow block 112, and then the water is sprayed through the high-pressure nozzle 113 to the surface of the hollow cylinder 121, and the impurities attached to the surface are washed off and discharged through the valve pipe 10, so as to ensure that the liquid can normally pass through the inside of the sieve hole 122, and ensure the normal operation of the centrifugal pump. At the same time, the second motor 9 is controlled to drive the hollow cylinder 121 to rotate, so that the high-pressure nozzle 113 cleans other surfaces of the hollow cylinder 121.
