Description

Technical Field

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

[0002] Wastewater treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] For example, the Chinese patent with publication number CN218774442U proposes a sewage treatment and sand removal device. The patent sets a sealing plate. By opening the sealing plate and pouring sewage into the filter box, the filter cloth and the filter plate cooperate with each other to facilitate the sand removal and filtration of the sewage. 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. The filter box can be taken out by holding the L-shaped rod to deal with the remaining sand and gravel. When it is necessary to speed up the discharge of the sediment, the sealing plate and all valves are closed, and the air pump and the exhaust pipe are used to discharge the sediment. Gas is injected into the sealed sand removal box to make the internal air pressure different from the external air pressure, and then the valve on the sand discharge pipe is opened to accelerate the discharge speed of the sediment through 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. However, in this solution, the sand and gravel are filtered by the filter cloth and filter plate, and then the sand and gravel in the filtered water are precipitated. However, when cleaning the sewage, the sand and gravel need to be discharged and cleaned manually, and some operation steps need to be performed to clean it up, which may be troublesome, occupying the time of users and wasting manpower, and there are certain limitations.
