The lower pulsator supports. The pressure plate and the pulsator disk are evenly covered with water distribution holes to play a role in distributing water. During backwashing, the backwash water enters the tank from the bottom and flows out of the tank. After the tank is filled with clean water, the inlet and outlet valves are closed. At the same time, the pressure plate lifts up the fiber ball filter, and the lower motor rotates, driving the large wave wheel to alternately rotate forward and backward. The static water in the tank can be quickly and positively reversed, so that the fiber ball filter is subjected to relatively large hydraulic oscillations. This process is repeated several times until the filter material is washed. During filtration, the filtrate goes high and low, the pulsator stops rotating, the pressure plate presses down the fiber ball, and the degree of compression is controlled by the encoder in advance. A trap can also be designed on the tank wall to collect loose fibers. According to how much the fiber is scattered, the addition and replacement of the fiber ball filler are determined. The filter realizes fully automated control and adjustment of filtration, backwashing, and compression. The number of rotations and angles of the upper rotary shaft are controlled by an encoder and a control system. The injection molding technician apprentices to control the stroke of the platen. All controls Both are implemented on one control panel.

Backwashing makes full use of hydraulic vibration and backwashing is complete. The use of a large pulsator can achieve rapid swirling in water. Therefore, its rotation speed is not high and the reversal is easy and rapid. The pulsator blades are smoother and the damage to the fiber ball is minimal. Due to the intermittent use of backwashing water during the backwash process, water is saved more than the original backwash method. This has great environmental and economic significance in the scarce water resources of the northern regions.
