Technical Field
[0001] This utility model relates to the field of centrifugal pump technology, specifically a washable centrifugal pump. Background Technology
[0002] A centrifugal pump is a device that uses the centrifugal force generated by the rotation of an impeller to transport liquids. It mainly uses the centrifugal force generated by the rotating impeller to draw in and discharge liquids, thereby realizing the transport of liquids. In order to facilitate the cleaning of centrifugal pumps, a cleanable centrifugal pump is needed.
[0003] In traditional centrifugal pumps, the pump is usually mounted directly on top of a base. The outer surface of the traditional centrifugal pump is easily corroded by the external environment. Therefore, a protective shell is added to the outer surface of the centrifugal pump. However, the protective shell is mostly fixed with screws, which can easily cause the outer surface of the screws to rust. This makes it difficult to easily disassemble the protective shell, thus affecting the cleaning efficiency of the centrifugal pump. Utility Model Content

[0023] In a preferred embodiment, a spring 8 is fixedly connected to the side of the inner wall of the cylinder 7. A circular plate 9 is fixedly connected to the end of the spring 8 away from the inner wall of the cylinder 7. The outer edge of the circular plate 9 is slidably sleeved with the inner wall of the cylinder 7. Through the cooperation of the spring 8 and the circular plate 9, the spring 8 pushes the circular plate 9 in the inner wall of the cylinder 7, and then the circular plate 9 pushes the outer edge of the docking plate 12 to be stably limited to the inner wall of the docking groove 10.
[0024] In a preferred embodiment, a docking plate 12 is slidably connected to the inner wall of the docking groove 10, and the shape and size of the outer edge of the docking plate 12 are adapted to the shape and size of the inner wall of the first slide 5 and the second slide 6. An adjusting rod 13 is fixedly mounted on the side of the docking plate 12. Through the cooperation between the docking plate 12 and the docking groove 10, the outer edge of the docking plate 12 passes through the inner wall of the first slide 5 and the inner wall of the second slide 6 to the inner cavity of the cylinder 7. Then, by rotating the docking plate 12, the outer edge of the docking plate 12 is assisted to dock with the inner wall of the docking groove 10.
[0025] In a preferred embodiment, a threaded ring 14 is fixedly sleeved on the outer edge of the adjusting rod 13 away from the docking plate 12. A sleeve 15 is threadedly connected to the outer edge of the threaded ring 14. An annular groove 11 is provided on the side of the heat dissipation frame 2 4, and the shape and size of the inner wall of the annular groove 11 are adapted to the shape and size of the outer edge of the sleeve 15. Through the cooperation of the threaded ring 14 and the sleeve 15, the sleeve 15 is rotated by the threaded outer edge of the threaded ring 14, which helps the outer edge of the sleeve 15 to dock with the inner wall of the annular groove 11. Then, by using the limiting of the docking plate 12 and the docking groove 10, as well as the limiting of the sleeve 15 and the annular groove 11, the stable docking and limiting of the heat dissipation frame 1 3 and the heat dissipation frame 2 4 are assisted.

[0028] Working principle: When the device is in use, heat dissipation frame 3 and heat dissipation frame 4 are connected, and the adjacent sides of auxiliary sealing gasket 21 and sealing gasket 22 are fitted together. Then, the adjusting rod 13 drives the outer edge of the connecting plate 12 through the inner wall of slide groove 5 and slide groove 6 into the inner cavity of cylinder 7. Then, the adjusting rod 13 is rotated, thereby driving the outer edge of the connecting plate 12 to rotate in the inner cavity of cylinder 7.
