The air cylinder 602 is fixedly installed inside the top end of the support frame 601 by bolts.

The piston 604 is installed in the air cylinder 602 by sliding movement. The lifting cylinder 605 is installed at the bottom end of the air cylinder 602 by insertion movement. The top end of the lifting cylinder 605 is fixedly installed in the middle of the bottom end of the piston 604 by bolts; by driving the liquid pushing plate 303 to move in the direction close to the partition 2, the air in the sealed airbag 304 is squeezed into the air cylinder 602 through the air pipe 603, so that the piston 604 moves downward in the air cylinder 602, and the lifting cylinder 605 is driven to descend through the piston 604;

[0038] The lifting mechanism 6 includes a lifting frame 606, a support rod 607, a return spring 608 and a rack 609.

[0039] Working principle: When the present invention is in use, the waste liquid discharged through the equipment housing 1 falls into the bottom end of the equipment housing 1 between the partition plate 2 and the ramp plate 302, and flows into the drain and exhaust pipe 301 by the waste liquid's own gravity, and is discharged through the drain and exhaust pipe 301, and exhausts air through the drain and exhaust pipe 301 at the same time. After starting the dual-axis motor 405, the second gear 407 is driven to rotate through the transmission shaft 406, and the first gear 403 is driven to rotate through the second gear 407. When the first gear 403 rotates, the slider 402 is driven to slide back and forth in the limit frame 401 through the reciprocating plate 404, and the push rod 305 is driven to reciprocate through the slider 402. The push rod 305 is driven to move back and forth, and the push rod 305 drives the liquid push plate 303 to continuously push the waste liquid on the bottom end of the equipment housing 1 into the drain and exhaust pipe 301, thereby accelerating the discharge speed of the waste liquid discharged by its own weight;

[0040] When the push plate 303 moves toward the direction close to the partition 2, the air in the sealed airbag 304 is squeezed into the air cylinder 602 through the air pipe 603, so that the piston 604 moves downward in the air cylinder 602, and the piston 604 drives the lifting cylinder 605 to descend, and the lifting cylinder 605 drives the lifting frame 606 to descend, so that the rack 609 follows the lifting frame 606 to descend, and in this process, the lifting frame 606 is kept stable by the support rod 607, and the return spring 608 is compressed, and the rack 609 is moved downward. When 09 descends, the fourth gear 507 is driven to rotate, so that the upper horizontal shaft 502 rotates with the fourth gear 507. When the upper horizontal shaft 502 rotates, the third gear 505 on the upper horizontal shaft 502 is driven to rotate, and the third gear 505 on the lower horizontal shaft 503 is driven to rotate through the chain 506, so that the lower horizontal shaft 503 and the upper horizontal shaft 502 rotate at the same time, so that the drainage wheels 504 on the upper horizontal shaft 502 and the lower horizontal shaft 503 rotate at the same time in the same direction, so as to drive the waste liquid in the pressure-carrying drainage pipe 501 to be discharged quickly;

[0041] When the push plate 303 moves in the opposite direction away from the partition 2, the air in the air cylinder 602 is drawn into the sealed air bag 304 through the air pipe 603, and the elastic force of the reset spring 608 drives the lifting frame 606 to rise, so that the rack 609 rises with the lifting frame 606. At this time, the rack 609 drives the fourth gear 507 to reverse, so that the discharge wheel 504 reverses and still accelerates the discharge of waste liquid in the pressure-carrying discharge pipe 501, thereby improving the waste liquid discharge efficiency and avoiding damage to the equipment caused by the backflow of waste liquid in the pipeline.
