The first limiting seat 8 and the second limiting seat 9 are both semi-circular ring seats, which can limit the first limiting ring 14 and the second limiting ring 16.

[0022] The working process of the corrosion-resistant ceramic pump described in Example 1 is as follows:

[0023] Before use, fix the base 1 of the device in a suitable position and connect the power supply. The device is equipped with an external controller, which is electrically connected to the drive motor 4. The operating status of the drive motor 4 can be adjusted by manually operating the external controller. The pump body 2, drive motor 4, pump shaft 5, and impeller 6 of the device are all existing components, and all of the above are existing technologies. When using the device, connect the outlet of the pump body 2 to the liquid storage device through a pipe. Start the drive motor 4 through the external controller. The drive motor 4, which is fixed by the motor housing 3, can drive the pump shaft 5 and impeller 6 inside the pump body 2 to rotate synchronously. Through the impeller 6, the pump body 2 can draw in liquid from the inlet and discharge liquid from the outlet. Liquid delivery is completed by discharging the liquid. A transmission block 10 is fixedly connected to the front side of the pump shaft 5. The first transmission shaft 11 is inserted into the transmission block 10. The pump shaft 5 can drive the first transmission shaft 11 and the second rotating shaft 12 to rotate. The rotation direction of the pump shaft 5 and the second rotating shaft 12 are opposite to the tightening direction to prevent the second rotating shaft 12 from dislodging. The first transmission shaft 11 and the second rotating shaft 12 can drive the first soft brush 13 and the second soft brush 15 to rotate. The first limiting seat 8 and the second limiting seat 9 can limit the first limiting ring 14 and the second limiting ring 16. The first limiting ring 14 and the second limiting ring 16 can control the rotation of the first soft brush 13 and the second soft brush 15. The soft brush 15 rotates stably, preventing the first drive shaft 11 and the second rotating shaft 12 from moving forward and ensuring their stable rotation. The rotating impeller 6 generates a backward suction force inside the pump body 2, further ensuring the stability of the first drive shaft 11 and the second rotating shaft 12. The first limit seat 8 and the second limit seat 9 can limit the limit block 18, preventing the filter plate 17 from rotating. This allows the first soft brush 13 and the second soft brush 15 to rotate relative to the filter plate 17, filtering the liquid through the filter plate 17. The first soft brush 13 and the second soft brush 15 clean the filter plate 17. The filtered liquid enters the pump body 2 through the mounting shell 7. If the filter plate 1... If the filter plate 17 is damaged, the first limiting seat 8 and the second limiting seat 9 can be removed, and the second rotating shaft 12 and the first transmission shaft 11 can be separated to remove and replace the filter plate 17. This device can limit the first soft brush 13, the second soft brush 15 and the filter plate 17 through the first limiting seat 8 and the second limiting seat 9. The filter plate 17 filters impurities in the liquid. The first transmission shaft 11 and the second rotating shaft 12 drive the first soft brush 13 and the second soft brush 15 to rotate, and the first soft brush 13 and the second soft brush 15 clean the filter plate 17. This device can avoid blockage and jamming inside the pump body 2 and prevent the pump body 2 from being damaged due to blockage or jamming.
