A sewage purification device

Abstract

A sewage purification device for removing impurities in sewage, belonging to the technical field of environmental protection equipment manufacturing, comprising a frame body, the frame body is provided with a water storage container with an upward opening, and the water storage container is provided with an upward opening and one side surface is The filter box of the filter screen, the inner bottom wall of the filter box is provided with a vertical solid impurity pushing device, and the water storage container is provided with a horizontal solid impurity pushing device matched with the vertical solid impurity pushing device at the opening of the filter box. The side wall of the water container is provided with an air plate corresponding to the filter screen, and the side wall of the water container is provided with a clean water outlet, a sloping plate, a drug injection pipe with an on-off valve, an emptying valve, and a water storage container in sequence below the filter box. There is a stirring device under the filter box inside the container, which solves the problem that no solid impurities are integrated with the flocculation and sedimentation, and the solid impurities on the filter screen cannot be automatically removed, and the solid impurities are easily stuck in the filter holes of the filter screen during the sewage filtration process.

Description

technical field [0001] The utility model relates to a sewage purification device, which is used for removing impurities in sewage, and belongs to the technical field of environmental protection equipment manufacturing. Background technique [0002] In the process of sewage treatment, many procedures are required. First, the solid impurities in the sewage should be removed, and then a flocculant should be added to precipitate other harmful substances in the sewage, and finally clear water is obtained. However, in the prior art, these two procedures They are all separated, so that the sewage needs to flow into the solid impurity removal device during the use process, and then the flocculation and sedimentation are carried out, which increases the investment of equipment and the cost is high. Secondly, in the process of solid impurity removal, usually the sewage It flows through the filter screen, and then the solid impurities in the sewage remain on the filter screen. The work...

Problems solved by technology

[0003] The purpose of the present invention is to aim at the shortcoming of prior art, adopt the mode that water storage container and rectangular filter box cooperate filter screen, wind plate, slant plate, injection pipe, design a kind of solid impurity on the filter screen that can be automatically removed, and It is a sewage purification device that can effectively prevent solid impurities from being stuck in the filter holes, and solves the problem that there is no solid impurity integrated with flocculation and sedimentation, and the solid impurities on the filter cannot be automatically removed and the solid impurities are easy to get stuck in the filter during the sewage filtration process. filter hole problem
