Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a solid waste filtering device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse. Wastewater 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.

[0003] According to the search, Chinese patent literature, announcement number: CN220294281U, discloses a solid waste filtering device for sewage treatment. This solution first lifts the top cover, then pours sewage into the rotating drum, and then starts the motor. When the output shaft of the motor rotates, it will drive the rotating drum to rotate at high speed. The centrifugal force generated by the high-speed rotation of the rotating drum will throw the water of the solid waste in the sewage out through a plurality of rectangular holes, and the water and sewage thrown out from the rectangular holes will be discharged through a plurality of water outlet holes. The water and sewage discharged from the plurality of water outlet holes will be filtered and discharged through the filter plate. While the rotating drum is rotating, it will also drive the first scraper to rotate in a circle and the second scraper to rotate. The circular rotation of the first scraper will scrape off the stains on the inner wall of the bottom of the installation cylinder and discharge them through the water outlet holes, while the second scraper will scrape off the stains on the inner wall of the installation cylinder and discharge them through the water outlet holes when it rotates. When the top cover is covered, the connecting rod will always move downward due to the tension of the tension spring, and the tension spring will always The downward movement will push the pressure plate to always press the solid waste in the sewage in the rotating drum, so as to achieve the effect of squeezing out the water in the solid waste in the sewage, lifting the moving rod will drive the receiving plate to rise, and the rising of the receiving plate will drive the dehydrated solid waste in the rotating drum to rise, and then the solid waste can be taken out of the rotating drum, and an annular block is provided on the outer wall of the rotating drum to seal the gap between the rotating drum and the inner wall of the mounting drum to prevent the solid waste from leaking from the water outlet hole, and the filter plate is a detachable structure, and the filter plate is connected to multiple legs through a slot to facilitate disassembly and cleaning, sewage can be poured into multiple rotating drums, and when the motor is started, the rotating drum can be driven to rotate and the water in the solid waste in the sewage in the rotating drum can be thrown out for solid-liquid separation, and the filter plate has a filtering effect on water and sewage, and the pressure plate can squeeze out the solid waste water in the sewage in the rotating drum through the tension of the tension spring, and the first scraper and the second scraper are provided on the rotating drum to clean the stains in the mounting drum. However, the solid waste filtration device for sewage treatment still has defects during use. The device has low sewage efficiency, a large workload, and does not perform secondary treatment on the sewage, which may cause some solid waste to remain in the water. Utility Model Content
