Description

Technical Field

[0001] The present application belongs to the technical field of environmental protection engineering, and specifically relates to a sewage filtering device used in environmental protection engineering. Background Art

[0002] Environmental protection engineering is a comprehensive engineering field that aims to protect and improve environmental quality and reduce pollution and damage to the atmosphere, water, soil and biodiversity. Sewage filtration treatment is involved in environmental protection engineering. Sewage filtration is the removal of impurities, particulate matter, organic matter and other pollutants in sewage through different technical means.

[0003] For example, the utility model patent with announcement number CN217449288U discloses a sewage filtering device for environmental protection engineering, which includes a treatment cylinder, and the side walls of the treatment cylinder are respectively provided with a water inlet and a water outlet distributed in an upper and lower manner. A filter box is provided on the inner side wall of the treatment cylinder between the water inlet and the water outlet, and the upper and lower end surfaces of the filter box divide the inner cavity of the treatment cylinder into an extrusion cavity and a water outlet cavity. An extrusion mechanism is provided in the treatment cylinder and above the water inlet. The extrusion mechanism includes an extrusion plate coaxially arranged with the treatment cylinder and capable of reciprocating up and down along the side wall of the treatment cylinder. The extrusion plate includes a ventilation plate and a gasket. The gasket is arranged on the lower end surface of the ventilation plate and the middle part of the gasket is fixed to the middle part of the ventilation plate. When the ventilation plate moves upward, a gap is formed between the upper end surface of the gasket and the lower end surface of the ventilation plate. When the ventilation plate moves downward, the upper end surface of the gasket fits with the lower end surface of the ventilation plate. Through the structure of the utility model, sewage can be quickly filtered, thereby realizing sewage treatment.

[0004] The device drives the rotating rod and the stirring blades to rotate through a motor to move the sludge and debris above the filter box, thereby avoiding the sludge and debris from clogging the drainage holes on the filter box as much as possible. Since sewage not only contains particulate matter but also contains certain debris, the debris blocked above the filter box of the device is not easy to discharge. When more debris accumulates above the filter box, it is easy to clog the drainage holes and affect the sewage treatment efficiency. Therefore, a sewage filtering device for environmental protection projects is provided. Utility Model Content

[0031] The implementation principle of an embodiment of a sewage filtering device used in an environmental protection project of the present application is as follows: the user first connects the liquid inlet pipe 4 with the external sewage, so that the external sewage enters the interior of the filter cylinder 2 through the liquid inlet pipe 4. When the sewage enters the interior of the filter cylinder 2, it will fall onto the upper conical filter plate 5. At this time, the sewage can be filtered by the set conical filter plate 5, so that the debris larger than the inner diameter of the drainage hole 6 remains on the conical filter plate 5. At this time, the user starts the motor 7, and the motor 7 drives the rotating shaft 8 and the scraper rod 10 to rotate. When the scraper rod 10 rotates, it drives the debris and particulate matter on the conical filter plate 5 to rotate and move. When the moving debris and particulate matter pass through the discharge pipe 14, they will be washed away by the continuously entering sewage water flow. The liquid flows downward through the discharge pipe 14 into the interior of the aggregate box 11 and falls on the filter plate 12. At this time, the filter plate 12 is set to facilitate re-filtering of debris and particulate matter so that the debris and particulate matter remain on the filter plate 12 and the liquid returns to the interior of the filter cartridge 2 through the L-shaped conduit 15. When personnel observe through the transparent glass 26 that there are a lot of debris and particulate matter inside the aggregate box 11, the sealing plate 13 can be opened to clean the debris inside the aggregate box 11. The device has a simple structure and is easy to operate. By discharging debris and particulate matter from the conical filter plate 5, the drainage hole 6 can be effectively prevented from being blocked. At the same time, personnel open the aggregate box 11 to facilitate cleaning of debris and particulate matter, thereby improving convenience.
