simultaneously, the first movable piston 36 moves to suck the clean water remained in the third piston cylinder 16 into the first piston cylinder 14, the second movable piston 49 moves upwards until the clean water cannot move, and meanwhile, the clean water in the backwash water tank 5 is sucked into the first piston cylinder 14 through the second liquid inlet pipe 38 so as to be used for backwash next time;
thus, the first movable piston 36 moves reciprocally, so that liquid can be filtered, and the filtering membrane 33 in the filtering cylinder 13 at the other side can be backwashed and cleaned for a plurality of times;
The reduction box 17 can drive a big gear to reduce speed or a worm gear to reduce speed, the reduction box 17 reduces speed to drive a short shaft 18 and a driving wheel 19 to rotate, under the drive of a belt 20, a vertical rod 21 and a first gear 22 are driven to rotate, when the liquid is filtered and a filtering membrane 33 is backwashed, the first gear 22 is not meshed with the second gear 23, when the first movable piston 36 moves and two rubber plugs 52 are not contacted with the filtering membrane 13, the first gear 22 is meshed with the second gear 23 at the moment (the result obtained by selecting the proper reduction box 17, the first gear 22 and the second gear 23 through multiple tests), and the first gear 22 rotates to drive the second gear 23 to rotate, thereby realizing the rotation of a supporting column 11, and the rotation angle is 180 DEG, and thereafter, the first gear 22 is not meshed with the second gear 23;
The support column 11 rotates to drive the mounting block 27, the shaft rod 12, the support ring 29 and the filter cartridge 13 to rotate, as shown in fig. 5, after the transmission gear 26 on the shaft rod 12 on the right side is separated from the arc rack plate 25, under the action of the torsion spring 28, the transmission gear 26 on the shaft rod 12 on the left side is meshed with the arc rack plate 25, so that the shaft rod 12 drives the filter cartridge 13 to rotate 180 degrees, and the positions of the filter cartridge 13 for filtering liquid and the filter cartridge 13 after backwashing the filter membrane 33 are exchanged, so that the filter membrane 33 for long-time use can be cleaned;
Because the rubber plug 52 moves downwards to be inserted into the filter cartridge 13 and presses the conical rubber sheet 32 to move downwards to be concave, as shown in fig. 6, in the process of rotating the filter cartridge 13 by 180 degrees, residual liquid in the filter cartridge 13 is blocked by the conical rubber sheet 32, so that the residual liquid can not drop into the box 1 to pollute equipment in the box 1, when the filtering membrane 33 in the filter cartridge 13 is washed, the conical rubber sheet 32 can be reset to be convex under the impact of clear water, as shown by the conical rubber sheet 32 at the lower right end of fig. 5, the residual liquid can be washed, and the conical rubber sheet 32 can not remain clear water;
So reciprocating can filter liquid, can clear up filtration membrane 33 simultaneously, can not lead to filtration membrane 33 to block up, can more effective filtration to liquid.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
