[0002] Sewage treatment tank is a device used to treat and purify domestic sewage or industrial wastewater. Its basic working principle includes multiple steps such as sedimentation, filtration, chemical reaction and biodegradation. The treated water is discharged through the drain outlet, which usually meets certain emission standards and can reduce pollution to the environment. Sewage treatment tanks are widely used in urban sewage treatment, industrial wastewater treatment and other fields, and are important facilities for protecting the environment.

[0003] The filtering structure in the sewage treatment tank can effectively filter impurities in the sewage, but it still has certain problems: the impurities filtered out need to be cleaned manually with the help of tools, and the cleaning process is cumbersome and time-consuming. During this process, the smell in the filter box will escape into the air in large quantities, and large amounts of inhalation will cause damage to the respiratory system of the staff; therefore, in view of the above situation, there is an urgent need to develop a sewage treatment tank for sewage treatment to overcome the shortcomings in current practical applications and meet current needs.

[0028] Preferably, the filter assembly 50 is provided with two filter buckets 501 distributed up and down, and two transmission parts 502 connected to the side of a single filter bucket 501 are installed. Specifically, the bottom of the filter bucket 501 is hollowed out, which can filter particulate matter in sewage. When the filter bucket 501 is in a filtering state, one end of it equipped with a sliding shaft 5011 is slightly higher than the other end. When the filter bucket 501 is driven to an inclined state by the driving cylinder 504 in conjunction with the parallelogram connecting rod structure 503 and the transmission part 502, one end of it equipped with a sliding shaft 5011 is lower than the other end. At this time, the filtered impurities will slide down, be received by the discharge trough 505, and be discharged to the outside of the box body 10, thereby achieving the effect of quickly cleaning and filtering impurities.

[0029] Preferably, two sliding shafts 5011 are fixedly provided on the side of the filter bucket 501 .

[0030] Preferably, a slide groove 5021 is provided at one end of the transmission member 502, and the slide groove 5021 is adapted to the slide shaft 5011. A positioning shaft 5022 is fixedly provided in the middle section of the side wall of the transmission member 502, and a rotating shaft 5023 is fixedly provided at the lower position of the side wall of the transmission member 502. A rotating seat 5024 is fixedly provided on the inner wall of the box body 10, and the end of the rotating shaft 5023 is rotatably connected to the rotating seat 5024. Specifically, the transmission member 502 is provided to have a transmission effect, which is used to drive the filter bucket 501 to rotate around the hinged position to achieve an inclined slag discharge effect.

[0031] Preferably, the parallelogram linkage structure 503 includes a linkage a5031, a linkage b5032 and a hinge seat 5033. Two linkages a5031 and two linkages b5032 are provided. Adjacent linkages a5031 and b5032 are hinged to each other. The hinge seat 5033 is fixed on the inner wall of the box 10. The middle section of the linkage b5032 is rotatably connected to the hinge seat 5033. Specifically, the parallelogram linkage structure 503 can cooperate with the transmission member 502 to drive at the same time.

[0032] Preferably, the discharge chute 505 is fixedly connected to the transmission member 502 along its axial direction. Specifically, the provided discharge chute 505 can receive the filtered impurities that slide down from the filter bucket 501 and discharge them to the outside of the box body 10 .

[0033] Preferably, the connecting rod a5031 and the connecting rod b5032 are located at a hinged position inside the box body 10 and are rotatably connected to the positioning shaft 5022, and the connecting rod a5031 and the connecting rod b5032 are located at a hinged position outside the box body 10 and are hinged to the bottom end of the driving cylinder 504.

[0034] Working principle: connect the water inlet pipe of the box 10 with the sewage to be filtered, and the sewage is discharged into the filter bucket 501 in the box 10. The water filtered by the filter bucket 501 naturally falls to the bottom of the box 10 and is discharged through the drain pipe at the lower position of the outer wall of the box 10. The impurities in the sewage are filtered out in the filter bucket 501. The staff regularly removes the filtered impurities. When the impurities are removed, first open the flip plate 30, and then push the garbage truck to the bottom of the slag discharge port 20, and then start the drive cylinder 504. The drive cylinder 504 drives the parallelogram connecting rod structure 503 to rotate around the hinge seat 5033, thereby driving the connecting rod b5032 and the transmission member 502 to rotate. When the transmission member 502 rotates, it will drive the discharge chute 505 fixed thereto synchronously. The filter hopper 501 is rotated and driven by the sliding groove 5021 at the end to cooperate with the sliding shaft 5011 to rotate around the hinged position, thereby driving the end of the filter hopper 501 near the slag discharge port 20 to tilt downward. At the same time, the discharge chute 505 will also be in an inclined state and will be against the end of the filter hopper 501. The residue filtered out of the filter hopper 501 will slide down and slide through the discharge chute 505 into the garbage truck outside, thereby automatically discharging the filtered residue. It should be noted here that an inlet pipe and a drain pipe are respectively installed on both sides of the box body 10. The inlet pipe is passed through the upper part of the side wall, and one end of the water inlet pipe located in the box body 10 extends to the top of the filter hopper 501, so that sewage can be introduced into the filter hopper 501. The drain pipe is located at the lower part of the side wall of the box body 10.
