Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a mobile integrated rural domestic sewage pretreatment device. Background Art

[0002] Due to the strong dispersion of urban and rural populations, the current model of household pretreatment plus effective collection after pretreatment for centralized treatment and then discharge in compliance with standards is often used to treat rural domestic sewage. The role of pretreatment is to intercept solids in domestic sewage, making it easier for the remaining sewage to flow into the centralized treatment link and reducing the load and difficulty of centralized treatment.

[0003] However, household pretreatment has some problems related to dredging. The solids trapped in the pretreatment process need to be cleaned regularly. If they are not cleaned in time, it is easy to cause blockage of the pretreatment equipment and pipelines, reducing the treatment efficiency of the pretreatment equipment. In addition, when blockage occurs, the solids in the sewage are not separated thoroughly, and manual cleaning is also very difficult. Therefore, the labor intensity of the cleaning staff is greatly increased. When blockage occurs, there is also the influence of rancid gases, which is not conducive to people's health and the surrounding environment. This increases the labor expenditure of environmental protection work in the village.

[0004] In order to solve the above problems, a Chinese patent (publication number: CN219002155U) discloses a mobile integrated rural domestic sewage pretreatment device, including a pretreatment device body and a waste box, the pretreatment device body includes a shell, a discharge port is provided on the side wall of the shell, and the waste box is connected to the outside of the discharge port of the shell. An inclined leak plate is installed in the shell, and a slide groove is provided on the inner wall of the shell on both sides of the leak plate. A slide plate is slidably connected in the slide groove, the slide plate is threadedly connected to a threaded rod, and the threaded rod is connected to a drive motor.

[0005] Although the above technical solution scrapes and cleans the solid garbage on the drain plate by setting a scraper, thereby avoiding the blockage of the main body of the pretreatment equipment, and achieving the purpose of automatically cleaning the solid matter of the main body of the pretreatment equipment, effectively avoiding the blockage of the main body of the pretreatment equipment, and improving the processing efficiency of the pretreatment equipment. However, the inventor found in the process of implementing the above technical solution that after the scraper cleans the solid matter to the waste box from top to bottom, if any solid matter falls between the scraper and the highest point on the way back to the highest point, it will be scraped to the highest point by the scraper, and then the solid matter near the highest point will accumulate more and more, eventually affecting the normal operation of the device. Utility Model Content

[0008] The working principle of this technical solution is as follows: when in use, first pour sewage, dirt, etc. into the shell through the opening on the top of the shell. The sewage, etc. will pass through the filter plate, while the solid matter will remain on the filter plate. Then, start the control component to drive the cleaning component to reciprocate on the top surface of the filter plate. When the scraper in the cleaning component moves toward the collecting component, it will scrape the solid matter into the collecting component.
