[0012] Beneficial effects

[0013] The present utility model provides an intelligent diaphragm pump. Compared with the prior art, it has the following beneficial effects:

[0014] 1. For this intelligent diaphragm pump, by setting an interception mechanism, the filter screen intercepts and filters impurities in the materials pumped by the diaphragm pump body, and then the materials enter the inside of the diaphragm pump body. The flow velocity sensor senses the flow velocity of the materials.

The outer side wall of the rotating plate 15 is rotatably connected to the inner side wall of the fixed shell 12. The filter screen 17 is fixed inside the rotating plate 15. The left end of the water inlet pipe 1 is fixedly connected to the right side of the fixed shell 12. The right end of the rotating plate motor 16 is fixedly connected to the left side of the fixed shell 12. The output shaft of the rotating plate motor 16 passes through the fixed shell 12 and is fixedly connected to the left side of the rotating plate 15. The filter screen 17 intercepts and filters impurities in the material pumped by the diaphragm pump body 6, and then the material enters the inside of the diaphragm pump body 6. The flow velocity sensor 11 senses the flow velocity of the material. If the lower filter screen 17 is blocked and the flow velocity of the material decreases, the PLC starts the rotating plate motor 19, and the rotating plate motor 19 drives the rotating plate 18 to rotate, so that the upper and lower filter screens 17 are exchanged, and thus the filter screen 17 is automatically replaced.

[0023] Further, the upper right of the diaphragm pump body 6 is fixedly connected to the left side of the circular shell 14. The inner side wall of the circular shell 14 is connected to the outer side wall of the circular plate 18.

The circular plate motor 16 drives the circular plate 15 to rotate, causing the water outlet 20 to rotate downward. This allows the material to enter the water guide pipe 13 and then enter the fixed shell 12, passing through the clogged filter screen 17 and impacting the filter screen 17. The material passes through the turbine fan 24, causing the turbine fan 24 to rotate. The turbine fan 24 drives the rotating rod 23 and the fixing strip 22 to rotate.

This can clean the clogged filter screen 17, and the impurities are discharged from the slag discharge pipe 3. After cleaning for a period of time, the PLC 10 starts the circular plate motor 19 to rotate the circular plate 18 back to its original position.

[0024] During operation, the filter screen 17 intercepts and filters the impurities in the material pumped by the diaphragm pump body 6, and then the material enters the inside of the diaphragm pump body 6. The flow rate sensor 11 senses the material flow rate. If the lower filter screen 17 is clogged, resulting in a decrease in the material flow rate, the PLC starts the rotating plate motor 19. The rotating plate motor 19 drives the rotating plate 18 to rotate, swapping the upper and lower filter screens 17, thus automatically replacing the filter screen 17. After the flow rate sensor 11 senses a decrease in the material flow rate, the PLC 10 starts the circular plate motor 16. The circular plate motor 16 drives the circular plate 15 to rotate, causing the water outlet 20 to rotate downward. This allows the material to enter the water guide pipe 13 and then enter the fixed shell 12, passing through the clogged filter screen 17 and impacting the filter screen 17. The material passes through the turbine fan 24, causing the turbine fan 24 to rotate. The turbine fan 24 drives the rotating rod 23 and the fixing strip 22 to rotate. The fixing strip 22 drives the brush wire 21 to rotate, and the brush wire 21 cleans the clogged filter screen 17. This can clean the clogged filter screen 17, and the impurities are discharged from the slag discharge pipe 3. After cleaning for a period of time, the PLC 10 starts the circular plate motor 19 to rotate the circular plate 18 back to its original position.
