Description

Technical Field

[0001] The utility model belongs to the technical field of rainwater pollutant separation, and in particular relates to rainwater pollutant separation equipment. Background Art

[0002] When it rains in the city, rainwater pollutants often carry a lot of garbage and debris. If these solid debris are directly discharged into the sewer without treatment, it is easy to cause blockage. Therefore, it is necessary to use rainwater pollutant separation equipment to filter out these solids.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the technology: the current rainwater pollutant separation equipment often only has one grille plate, and the grille plate can only perform basic filtration and filter out some larger solids, while some objects such as plastic sheets, branches, soil, pebbles, etc. cannot be filtered out, so blockage may still occur.

[0004] To this end, we proposed a rainwater pollutant separation device to solve the above problems. Utility Model Content

A push plate that fits the filter screen is also arranged above the filter screen in the inner cavity of the separation dish, and one end of the push plate is threadedly sleeved on the screw, and the other end thereof is slidably sleeved on the sliding rod.

[0009] As a preferred embodiment, a top cover plate is integrally welded above the separation dish, wherein a grille plate is placed on the top cover plate; the grille plate can intercept larger objects brought by the flow of rainwater, thereby preventing excessively large solid debris from entering the separation dish.

[0010] As a preferred embodiment, a cover is provided on the outside of the servo motor, wherein the cover is welded to the mounting base; the cover can protect the servo motor, and heat dissipation holes for dissipating the servo motor are provided at the bottom of the cover, so that the servo motor can dissipate heat without getting water in, and the servo motor needs to be powered by external power facilities.
