Multi-filling device for oxygen in domestic sewage based on self-gravity action

Abstract

The invention relates to the technical field of sewage treatment, and discloses a multi-filling device for oxygen in domestic sewage based on self-gravity action. The multi-filling device comprises aframe, wherein breather pipes are movably hinged to the left end and the right end of the interior of the frame, and uniformly distributed fixing plates are fixedly mounted in the frame. According tothe filling device, the driving device drives the screw rod to rotate, the screw rod drives the rotating wheel to rotate, the sliding plates are driven to slide on the guide rail rods under the actionof the guide rods, and the connecting holes and the movable connecting rods are matched, so that when the sliding plates get close to each other, the movable connecting rods can be matched to extrudethe filter screen, the pore diameters of the filter screens is reduced, on the contrary, when the sliding plates get away from each other, the pore diameters of the filter screens is increased, and when sewage passes through the three filter plates in sequence, the pore diameters of the filter screens are increased, and the pore diameters of the filter screens are different in the moving processof the sliding plate due to the inclined design of the breather pipes of the three filter plates so as to achieve the effects of multi-distribution filtration and filter screen blockage prevention.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-filling device for oxygen in domestic sewage based on its own gravity. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, etc. Domestic sewage contains many impurities. If it is directly put into the sewage treatment plant for treatment, Otherwise, the treatment device may be blocked, and the control effect on the concentration of dissolved oxygen in the sewage is poor, and the oxygen and sewage cannot be fully mixed. [0003] At present, before the domestic sewage is treated, the sewage needs to be filtered first, and the filtration is inseparable from the use of the filter screen. If the filter hole is too large, it will cause the solid waste to be treated uncleanly. If the filter hole is small, the fi...
