A sewage filter device

Abstract

The invention relates to a sewage filter residue device, which effectively solves the problem that the filter screen is not cleaned in time and needs electric power; Conveyor belt of the box; resettable pins are installed on the box, and the pins block the partition, so that the filter does not rotate under the impact of the water flow; the inside of the cylinder is penetrated by a pipe fixed in the front and rear direction, and the pipe is fixed with a shunt The bottom of the distribution pipe is provided with a water collection tank that can move up and down and reset upward; the water collection tank is provided with a siphon tube, the bottom of the water collection tank is fixed with a vertical rack, and the bottom of the water collection tank is fixed with a rotating shaft. The rack meshes with the gears, and the water collecting tank descends, which can drive the conveyor belt to rotate; the water collecting tank rises, and the pin can be reciprocated to move once, so that the filter can be rotated once; the invention improves the speed and quality of sewage filtration, and simplifies operation, saving power.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage filter residue device. Background technique [0002] When filtering sewage, it is necessary to use a filter screen to remove a large amount of suspended matter in the sewage, but when filtering, debris will accumulate on the screen, thereby oppressing and blocking the filter screen, and the water output of the filter screen will be reduced. Filtration efficiency will be reduced. [0003] Most of the existing ones use inclined chain conveyor belts to filter and discharge debris, but this kind of filtering effect is limited; small particles cannot be filtered and pass directly through the chain; large-volume debris cannot be taken away in time, A large number of debris will gather on the front side of the filter device; at the same time, there are various other filter devices, because the filter screen cannot be replaced in time, which will affect the filtering effect; at ...
