[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 5 It can be seen that a biological extraction filtering device includes two filters 1 arranged in reverse parallel, a filter screen 2 is arranged in the filter 1, the filter screen 2 is arranged at a position close to the end of the filter 1, the filter screen 2 divides the filter 1 into a filter chamber 3 and a liquid outlet chamber 4, a piston 5 is slidably arranged in the filter chamber 3, a liquid inlet 6 is arranged at the end of the filter chamber 3, the liquid inlet 6 of the two filters 1 is connected to the same liquid inlet pipe 12, the liquid inlet pipe 12 is connected to the material box, a liquid discharge port 7 is arranged in the middle of the filter chamber 3, the liquid discharge ports 7 of the two filters 1 are connected to the waste liquid tank 14, the liquid outlet chamber 4 is connected to the liquid outlet pipe 8 and the liquid storage pipe 9, the liquid outlet pipes 8 of the two filters 1 are connected to the liquid storage tank 13, the piston 5 is controlled by a connecting rod 10 penetrating the end of the filter 1, and the connecting rod 10 in the two filters 1 is connected to the same double-headed hydraulic cylinder 1 1, the double-headed hydraulic cylinder 11 controls two filters 1 at the same time. Since the two filters 1 are set in opposite directions, the two filters 1 are in opposite working states when controlled by the double-headed hydraulic cylinder 11. When one filter 1 is filtering, its piston 5 moves toward the direction close to the filter screen 2, so that the essence is filtered by the filter screen 2. The piston 5 of the other filter 1 is away from the filter screen 2, and the essence stored in the liquid storage tube 9 can flow in the reverse direction to backwash the filter screen 2 and wash away the impurities attached to the filter screen 2. When the piston 5 passes through the drain port 7, the essence containing impurities is discharged from the drain port 7 and collected in the waste liquid tank 14. When the piston 5 moves to the end of the filter 1, the essence in the material box is injected into the filter 1 through the liquid inlet 6, and the drain port 7 is closed at this time.

[0020] When the piston 5 is away from the filter screen 2 , the liquid outlet pipe 8 is in a closed state, and the essence liquid stored in the liquid storage pipe 9 passes through the filter screen 2 in the reverse direction under the action of negative pressure to backwash the filter screen 2 .

[0021] During the reciprocating motion of the double-headed hydraulic cylinder 11, the connecting rod 10 and the filter 1 are alternately filtered and backwashed on the filter screen 2, thereby reducing the amount of attachments on the filter screen 2 and improving the filtering efficiency of the filter screen 2, thereby reducing the downtime for maintenance and further improving the filtering efficiency.

[0022] A control valve 15 is provided at the liquid inlet 6, and the liquid inlet 6 is opened at an appropriate time to allow the essence to enter the filter chamber 3. A solenoid valve 16 is provided in the liquid discharge port 7 and the liquid outlet pipe 8, and the liquid discharge port 7 is opened when the piston 5 moves in the reverse direction, so that the essence containing impurities is discharged from the liquid discharge port 7. At this time, the liquid outlet pipe 8 is closed, and the essence in the liquid storage pipe 9 can flow in the reverse direction under the action of negative pressure to realize backwashing of the filter screen 2.

[0023] A one-way valve 17 is provided at the outer end of the liquid storage tube 9, and the flow direction is one-way flow from the outside to the inside of the liquid storage tube 9. During filtration, the filtered essence enters the liquid storage tube 9 for storage. When the piston 5 moves in the reverse direction to form a negative pressure in the filter chamber 3, due to the presence of the one-way valve 17, the essence there will flow in the reverse direction, backwashing the filter screen 2, and reversely flushing the attachments on the filtering side of the filter screen 2, and flowing out from the discharge port 7 with the essence.

[0024] Compared with the prior art, the utility model has the following beneficial effects: a portion of the filtered essence is retained and can be used for backwashing the filter screen without burdening the filter screen, reducing the amount of attachments on the filter screen and improving the filtering efficiency.
