After injecting the production water of liquid fertilizer into the inside of the filter cylinder 103 through the water inlet pipe 120, start the high-speed motor 122 to drive the filter cylinder 103 to rotate inside the tank body 101, so as to perform active centrifugal filtration treatment under the cooperation of the filter cylinder 103, the first filter layer 104 and the second filter layer 105. When water discharge is required, the water pump 124 can be started to perform efficient suction water discharge through the suction port 121, and the filtered water is discharged from the inside of the tank body 101 through the water outlet 123.

The electromagnet 112 is adapted to the iron plate 125. Since the collection box 113 is installed at the inner bottom of the filter cylinder 103, the impurities generated after filtration accumulate inside the collection box 113.

After the electromagnet 112 is powered on, under the magnetic action, the electromagnet 112 is firmly connected to the iron plate 125. Start the winding and unwinding assembly, wind up the winding and unwinding rope 111, so as to take out the collection box 113 from the inner bottom of the filter cylinder 103, which is convenient for cleaning the impurities in the collection box 113 and avoiding affecting the subsequent use of the filtration equipment.

The output gear 115 is meshed with the transmission tooth part 126. Start the driving motor 114 to drive the output gear 115 to rotate. Since the output gear 115 is meshed with the transmission tooth part 126, the rotating disk 108 is driven to rotate at the end of the mounting seat 107.

[0028] Meanwhile, the motor 116 is installed at the bottom of the connecting arm 110. The output end of the motor 116 is provided with the gear reduction box 117. The output end of the gear reduction box 117 is provided with the first winding and unwinding wheel 118. The winding and unwinding rope 111 is arranged on the first winding and unwinding wheel 118. Start the motor 116, and drive the first winding and unwinding wheel 118 to rotate by using the gear reduction box 117, so as to complete the winding and unwinding of the winding and unwinding rope 111.

A cable 128 is arranged on the second winding and unwinding wheel 119. The cable 128 is used to supply power to the electromagnet 112. Through the arrangement of the second winding and unwinding wheel 119, the winding and unwinding of the cable 128 is completed.

[0030] When using the filter for liquid fertilizer production in this embodiment, after injecting the water for liquid fertilizer production into the interior of the filter cylinder 103 through the water inlet pipe 120, start the high-speed motor 122 to drive the filter cylinder 103 to rotate inside the tank body 101. Thus, under the cooperation of the filter cylinder 103, the first filter layer 104 and the second filter layer 105, active centrifugal filtration treatment is carried out. When water needs to be discharged, the water pump 124 can be started, and efficient suction and discharge of water is carried out through the suction port 121. The filtered water is discharged from the interior of the tank body 101 through the water outlet 123. And since the collection frame 113 is installed at the inner bottom of the filter cylinder 103, the impurities generated after filtration accumulate inside the collection frame 113. When it is necessary to clean the impurities in the filter cylinder 103, open the cover plate 102, start the rotating assembly to drive the rotating disk 108 to rotate on the upper surface of the mounting seat 107, drive the connecting arm 110 to rotate through the support arm 109, so that the winding and unwinding assembly rotates to the upper end at the center of the tank body 101. Then start the winding and unwinding assembly, lower the winding and unwinding rope 111, so that the electromagnet 112 descends to the inner bottom of the filter cylinder 103. After the electromagnet 112 is powered on, under the magnetic action, the electromagnet 112 is firmly connected to the iron plate 125. Start the winding and unwinding assembly to wind up the winding and unwinding rope 111, so as to take out the collection frame 113 from the inner bottom of the filter cylinder 103, which is convenient for cleaning the impurities in the collection frame 113 and avoiding affecting the subsequent use of the filtering equipment.
