Description

A new type of sewage treatment circulation device

Technical Field

The utility model relates to the field of sewage treatment, in particular to a novel sewage treatment circulation device.

Background Art

Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a 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, catering, etc., and is increasingly entering the daily lives of ordinary people.

The Chinese patent with publication number CN219149374U discloses a circulating filtration sewage treatment device, including a sewage treatment box and a screw conveying pump. The sewage treatment box is provided with a treatment inlet pipe, and a liquid inlet hole is opened on the top inner wall of the sewage treatment box. The liquid inlet hole is connected with the treatment inlet pipe. A sewage filter plate is fixedly installed on the inner wall of the sewage treatment box. The circulating filtration sewage treatment device pours the sewage to be treated and filtered from the treatment inlet pipe. After pouring, the sewage will be filtered from the upper position of the sewage filter plate under the inclination of the guide plate. The unfiltered sewage will pass through the waste liquid reflux hole and enter the reflux collection box. The filtered aqueous solution will enter the collection bucket on the filter collection component. The sewage falling into the reflux collection box will be liquid spirally conveyed by the screw conveying pump and flow into the treatment inlet pipe again for circulating filtration treatment, so that the sewage can be effectively filtered.

In the above-mentioned prior art, in short, an inclined filter plate is arranged in the filtering device, and the sewage falls from the top of the filter plate for filtration. Since the impurities in the sewage are easy to clog the filter mesh holes, the sewage that cannot be filtered flows from the opening arranged on the outer wall of the filtering device to the reflux collection box, and is pumped to the upper side of the filter plate again by the screw conveying pump, thereby completing the circulation treatment of the sewage. However, in the process of the sewage returning to the collection box, due to the lack of obstruction of the flow of impurities, after the filter mesh holes are blocked, excessive impurities will also enter the collection box along the opening. Among them, large-size impurities will also interfere with the operation of the screw conveying pump and affect the smoothness of the pipeline. In the collection box without a shield, the odor of the sewage will also drift outward. For this reason, we have proposed a new type of sewage treatment circulation device.

Utility Model Content

The purpose of the utility model is to provide a novel sewage treatment circulation device to solve the problems raised in the above background technology.

To achieve the above-mentioned purpose, a novel sewage treatment circulation device comprises a sewage treatment tank, a water inlet is provided on the top of the sewage treatment tank, an inclined guide plate is fixedly connected to the interior of the sewage treatment tank at the lower side of the water inlet, a filter plate is inserted into the interior of the sewage treatment tank at the lower side of the guide plate, and the filter plate is stepped, a closed reflux box is fixedly connected to the outer wall of the sewage treatment tank, a pump is arranged inside the reflux box, a reflux pipe is installed at one end of the pump, and the other end of the reflux pipe extends to the upper side of the guide plate.

A return pipe 7 is installed at one end of the pump 6, and the other end of the return pipe 7 extends to the upper side of the guide plate 3.

Specifically, the filter plate 4 includes two baffles 8, and a plurality of straight plates 9 are fixedly connected to the inner sides of the two baffles 8 near the lower ends, and vertical plates 10 are fixedly connected between the plurality of straight plates 9, and filter holes are provided on the surfaces of the straight plates 9 and the vertical plates 10; the baffles 8 are used to prevent the overflow of sewage on the surfaces of the straight plates 9 and the vertical plates 10, and the stepped straight plates 9 and the vertical plates 10 can not only filter the sewage, but also separate and intercept the impurities flowing on their surfaces in sections.

On the basis of the above-mentioned scheme, both sides of the outer wall of the sewage treatment tank 1 are rotatably connected with rotating plates 11, and the two rotating plates 11 are respectively located on both sides of the filter plate 4. When the rotating plates 11 are erected, they can prevent the filter plate 4 from moving horizontally. When the filter plate 4 needs to be taken out for cleaning, the rotating plates 11 are rotated so that there is no horizontal overlap between the rotating plates 11 and the filter plate 4, and the filter plate 4 can be pushed out of the sewage treatment tank 1.

A hopper 12 is provided at the lower side of the filter plate 4 inside the sewage treatment box 1 to collect the filtered sewage, and a water storage chamber is provided at the lower side of the hopper 12 inside the sewage treatment box 1 to store the sewage.
