Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a sewage treatment sand removal device. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. Now, with the rapid development of the modern economy, people have higher and higher requirements for the quality of water bodies. Urban sewage usually contains a lot of sediment. Therefore, it is generally necessary to settle and separate the sand and gravel in the sewage before sewage treatment.

[0003] Announcement No.: CN218774442U, discloses a sewage treatment and sand removal device. When the filtered water falls into the sealed sand removal box for sedimentation, after sedimentation, the water is drained through the drain pipe, and the sediment is discharged through the sand discharge pipe. By holding the L-shaped rod with hand, the filter box can be taken out to deal with the remaining sand and gravel; when it is necessary to speed up the discharge speed of the sediment, the sealing plate and all valves are closed, and gas is injected into the sealed sand removal box through the air pump and the exhaust pipe to make the internal air pressure different from the external air pressure, and then by opening the valve on the sand discharge pipe, the discharge speed of the sediment is accelerated by atmospheric pressure. This is not only simple to operate and convenient for collecting sand and gravel, but also can enhance the filtration efficiency of sand and gravel and avoid affecting the filtration effect.

[0004] In the above patent, although the sewage can be desanded, the sand and gravel after filtering are not easy to clean during the sewage desanding process, and it is more labor-intensive to collect and clean them, and the operation is inconvenient, which affects the efficiency and quality of sewage desanding. Therefore, it is necessary to provide a sewage treatment desanding device. Utility Model Content

[0030] like Figure 1 and Figure 1 As shown, the box unit 100 includes a treatment box 101, a universal wheel 102 fixedly connected to the bottom of the treatment box 101, a sewage inlet pipe 103 fixedly connected to the front end surface of the top of the treatment box 101, and a drainage pipe 104 fixedly connected to one side of the bottom of the treatment box 101. The treatment box 101 injects sewage into the interior through the sewage inlet pipe 103 for sand removal treatment, and the treated sewage is discharged through the drainage pipe 104.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the frame unit 200 includes a gantry 201 fixedly connected to the top of the treatment box 101, and a slide groove 202 opened on the inner wall surface relative to the gantry 201. By arranging the gantry 201 on the top of the treatment box 101, it is convenient to adjust the overall lifting of the sand filter unit 300, thereby facilitating the sand removal operation of the sewage and the collection and cleaning of sand and gravel.

[0032] like Figure 1 — Figure 3As shown, the sand filter unit 300 includes a fixed frame 301 arranged between the inner walls of the gantry 201, a sand filter net 302 fixedly connected between the inner walls of the fixed frame 301, fixed slots 303 opened on the tops of both sides of the fixed frame 301, and through holes 304 opened on the inner wall surfaces relative to the fixed frame 301. By setting the fixed frame 301 adapted to the internal dimensions of the treatment box 101, a seamless connection can be formed to ensure that sand and gravel in the sewage will not leak and that the sand is removed cleanly. The fixed slots 303 are set to facilitate the positioning and insertion of the fixed plug plate 506, thereby facilitating the card-mounting and fixing.

[0033] like Figure 1 — Figure 3 As shown, the clamping unit 400 includes a fixing frame 401 fixedly connected to the inner wall surface relative to the sand filter unit 300, and a movable clamping column 403 movably arranged inside the fixing frame 401 for clamping and fixing the sand filter unit 300.

[0034] Working principle: When it is necessary to perform sewage sand removal, the fixed slot 303 at the top of the fixed frame 301 is aligned with the fixed plug plate 506 and then the movable clamping column 403 is pulled by the pull earring 404. The pulling of the movable clamping column 403 drives the limit plate 405 to compress the reset spring 406. After the fixed plug plate 506 is fully inserted into the fixed slot 303, the restraint of the pull earring 404 is released, and the reset spring 406 loses its force and recovers elastically, so that the movable clamping column 403 passes through the through hole 304 and enters the fixed plug plate 506. 6, the fixing frame 301 is fixed to the inside of the positioning slot 507 on one side, so as to complete the clamping and fixing of the fixing frame 301, so as to carry out the sand removal operation of the sewage. When the sand and gravel need to be cleaned after the sand removal of the sewage is completed, the movable clamping column 403 is pulled out of the positioning slot 507 by pulling the earring 404, so that the fixing frame 301 loses its limiting effect, and then the fixing frame 301 is removed to clean the sand and gravel on the sand filter net 302. This structure can quickly process sand and gravel, saves manpower and time, is convenient and quick to operate, and the sand and gravel are processed cleanly and thoroughly, thereby improving the quality of sand removal from sewage.
