The lower end of the lever 22 is fixedly connected to the eccentric wheel 23, and the eccentric wheel 23 is driven to rotate by the rotating motor 24.

[0038] Furthermore, the present invention can convert the driving force of the driving motor 31 into a linear reciprocating motion of the adjustment seat 20 by setting an eccentric wheel 23, a lever 22 and a rectangular slot 21 for use together, so that the forward wheel 26 and the reverse wheel 27 can be alternately engaged with the reference wheel 25, and the driving shaft 29 and the driven shaft 30 are connected by two sets of docking wheels 28, so that the driving shaft 29 and the driven shaft 30 have opposite directions, so that the reference wheel 25 drives the driving screw 19 to rotate forward and reverse, and under the cooperation of the piston rod 12, the transverse rack 13, the center wheel 14, the center shaft 15, the driven wheel 16, the driven rack 17 and the nut seat 18, the rotational motion of the driving screw 19 can be converted into the synchronous reverse piston motion of the No. 1 piston plate 8 and the No. 2 piston plate 9, thereby achieving a dual-channel filtration and concentration effect.

[0039] like Figure 9-11As shown, the adjusting seat 20 is limitedly slidably installed in the post-processing tank 3, and a sliding groove for accommodating the driving screw 19 is provided on one side of the adjusting seat 20, and the other side of the adjusting seat 20 acts on the first valve plate 6 and the second valve plate 7 through a linkage assembly. The linkage assembly includes a rotating shaft 32, a cylindrical cam 33 and a cylindrical pin 34, and the rotating ends of the first valve plate 6 and the second valve plate 7 are fixedly plugged with a rotating shaft 32, and each set of rotating shafts 32 is coaxially fixedly connected with a set of cylindrical cams 33, and the two sets of cylindrical cams 33 are provided with a quarter-turn spiral groove with opposite directions, one end of the cylindrical pin 34 is plugged into the spiral groove, and the other end of the cylindrical pin 34 is fixedly connected to the adjusting seat 20.

[0040] Furthermore, by setting a cylindrical pin 34 for use with a quarter-turn spiral groove on the cylindrical cam 33, the linear reciprocating motion of the adjusting seat 20 can be converted into a synchronous reverse 90° flipping motion of the first valve plate 6 and the second valve plate 7, and the mechanical linkage is strong, so that the first mud discharge pipe 302 and the second mud discharge pipe 303 can be adaptively opened or closed according to the movement state of the No. 1 piston plate 8 and the No. 2 piston plate 9, thereby facilitating the continuous collection and treatment of the second filter sludge.

The upper end of each group of longitudinal movement seats 46 is fixedly connected with a contact bar 47, and the lower end of each group of longitudinal movement seats 46 is fixedly connected with a second return spring 48. The side of the contact bar 47 close to the transverse rack 13 is arranged in an arc shape. The first sealing plate 10 and the second sealing plate 11 are both limitedly rotatably installed on a group of longitudinal movement seats 46, and the ends of the first sealing plate 10 and the second sealing plate 11 are coaxially fixedly connected with a group of lateral wheels 35. The lateral wheels 35 are meshingly connected with the pushing rack 36, and the pushing rack 36 is connected to the translation seat 37.

[0042] Furthermore, by setting the upper end of the interference bar 47 into an arc shape, the horizontal movement of the transverse rack 13 can be converted into a linear downward movement of the longitudinal movement seat 46, and through the design of the lateral wheel 35, the pushing rack 36, the translation seat 37, the base 3701, the inner moving seat 40, the main push rod 42, the longitudinal push plate 43 and the first return spring 45, the interference force exerted on the T-shaped contact block 44 can be converted into a horizontal movement of the translation seat 37 and the inner moving seat 40, thereby realizing the downward movement of the first sealing plate 10 and the second sealing plate 11 and then a 90° rotational movement, so that the first sealing plate 10 and the second sealing plate 11 can open or close the leakage hole 304 well.

[0045] When the present invention is in use: first, the sludge treated by the pool body 1 enters the three-way cavity 301 through the primary filter mud discharge pipe 2. At this time, the rotating motor 24 is turned on to drive the eccentric wheel 23 to rotate. The lever 22 on the eccentric wheel 23 acts on the rectangular slot 21, so that the adjustment seat 20 is subjected to force and moves horizontally. When the adjustment seat 20 moves toward the direction of the second valve plate 7, the cylindrical pin 34 thereon acts on the spiral groove, so that the second valve plate 7 flips downward and blocks the upper end of the second mud discharge pipe 303, and the first valve plate 6 flips upward and opens the lower end of the first mud discharge pipe 302. The forward wheel 26 inside the adjustment seat 20 is meshed and connected with the reference wheel 25, so that the driving screw 19 performs a forward rotation movement, and under the rotational action of the inner and outer spirals, the nut seat 18 drives the driven rack 17 toward the direction of the adjustment seat 20. The driven rack 17 acts on the driven wheel 16, so that the central wheel 14 coaxially connected with the driven wheel 16 also rotates synchronously and acts on the two sets of transverse racks 13. The transverse racks 13 act on the piston rod 12, so that the No. 2 piston plate 9 retracts inward and the No. 1 piston plate 8 extends outward. In this process, the transverse rack 13 close to the side of the No. 2 piston plate 9 moves away from the interference strip 47, and the transverse rack 13 close to the side of the No. 1 piston plate 8 squeezes the interference strip 47, so that the second blocking plate 11 first turns upward 90° and then moves upward in a straight line to block the leakage hole 304 close to the side of the No. 2 piston plate 9, while the first blocking plate 10 first moves downward and then turns downward 90° to open the leakage hole 304 close to the side of the No. 1 piston plate 8; at this time, the sludge in the three-way cavity 301 is concentrated on this side of the No. 2 piston plate 9; When the adjusting seat 20 moves toward the first valve plate 6, the cylindrical pin 34 thereon acts on the spiral groove again, so that the second valve plate 7 flips upward and opens the upper end of the second mud discharge pipe 303, and the first valve plate 6 flips downward and closes the lower end of the first mud discharge pipe 302. The reverse wheel 27 inside the adjusting seat 20 is meshed and connected with the reference wheel 25, so that the driving screw 19 rotates in the opposite direction, and under the rotational action of the inner and outer spirals, the nut seat 18 drives the driven rack 17 to move in the direction away from the adjusting seat 20. The driven rack 17 acts on the driven wheel 16 again, so that the center wheel 14 coaxially connected to the driven wheel 16 also rotates synchronously and acts on the two sets of transverse racks 13. The strip 13 acts on the piston rod 12, causing the No. 1 piston plate 8 to retract inward and the No. 2 piston plate 9 to extend outward. During this process, the first sealing plate 10 first flips upward 90° and then moves upward in a straight line to block the leakage hole 304 near the side of the No. 1 piston plate 8, while the second sealing plate 11 first moves downward and then flips downward 90° to open the leakage hole 304 near the side of the No. 2 piston plate 9; at this time, the sludge in the three-way chamber 301 is concentrated on this side of the No. 1 piston plate 8, and the sludge originally on the side of the No. 2 piston plate 9, during the process of being pushed, its moisture enters the second liquid storage chamber 306 through the leakage hole 304, and the filtered mud is pushed into the second mud discharge pipe 303 for centralized collection.
