[0025] See also Figures 1 to 5 The present utility model provides a technical solution: a chemical pump for chemical production, comprising: a pump body 1, a liquid inlet pipe 2, and a liquid outlet pipe 3. The end of the liquid inlet pipe 2 away from the pump body 1 is provided with a mounting groove 9, the interior of which is provided with a mounting ring 8. One end of the mounting ring 8 is connected to a fixing frame 5, the interior of which is provided with a filter screen 4. A connecting flange 19 is fixedly sleeved on the outer wall of the end of the liquid inlet pipe 2 away from the pump body 1, which can connect the liquid inlet pipe 2 to the liquid delivery pipe. The outer wall of the fixing frame 5 is provided with a sealing groove 13, the inner wall of which is fixedly connected to a rubber ring 12, which can strengthen the tightness of the connection between the fixing frame 5 and the inner wall of the liquid inlet pipe 2.

[0026] A first connecting rod 10 and a second connecting rod 11 are connected between the fixed frame 5 and the mounting ring 8. A limiting block 6 is installed at one end of the first connecting rod 10, and a limiting groove 7 is provided on the inner wall of the liquid inlet pipe 2 near the limiting block 6. Four first connecting rods 10 are evenly arranged and fixedly installed between the mounting ring 8 and the fixed frame 5. The cross-sections of the four first connecting rods 10 are all semicircular, and one end of the four first connecting rods 10 is fixedly connected to the adjacent limiting blocks 6. The four limiting blocks 6 are all slidably installed in the adjacent limiting grooves 7, and one end of the four limiting grooves 7 is connected to the mounting groove 9, which can limit the first connecting rod 10.
