[0037] The circulating filtration assembly 3 includes an input pipe 31, a high - pressure over - current pipe 32, and a filtrate recovery pipe 33. The liquid in the liquid storage tank 2 enters the high - pressure over - current pipe 32 through the input pipe 31, and after being filtered by the high - pressure over - current pipe 32, it enters the filtrate recovery pipe 33 and is re - input into the liquid storage tank 2. The input pipe 31 is provided with a liquid injection control valve 311 and a drain valve 312. The end of the drain valve 312 is provided with a drain pipe 313, and the end of the drain pipe 313 leads into the liquid storage tank 2; a pressure indicator 314 is also provided on the input pipe 31.

The slotted plate 321 is provided with filtering holes of a specified aperture for filtering particles in the liquid. Particles smaller than the aperture can pass through the slotted plate 321, while particles with a larger aperture are intercepted by the slotted plate 321. The incoming liquid can pass through the slotted plate 321, and the particulate matter will be retained above the slotted plate 321. At the bottom of the high-pressure overcurrent pipe 32, a support ring 324 and a sealing cover 325 are provided.

The liquid suction pipe 431 is connected to the bottom of the liquid storage tank 2, and the output pipe 432 is connected to the input pipe 31. The pump body 43 can pump the liquid in the liquid storage tank 2, then pressurize it, and input the pressurized liquid into the high-pressure overcurrent pipe 32 through the input pipe 432.

[0042] An adjusting handwheel 421 for adjusting the transmission ratio of the gearbox 42 is provided on the gearbox 42. The adjusting handwheel 421 can adjust the rotation speed of the pump body through the gearbox 42, thereby adjusting the liquid infusion speed and the liquid infusion pressure.
