Filtering device capable of quickly treating sewage blockage

Abstract

The inventin discloses a filtering device capable of quickly treating sewage blockage. The filtering device comprises a bottom plate and a support hinged to one side of the bottom plate; a through pipe is fixedly arranged at the upper end of the support; a feeding port is formed in the upper end of the through pipe, a discharging port is formed in one side of the through pipe, and a supporting disc is connected to the bottom of the through pipe; a plurality of first filtering pieces are movably connected between the upper side of the supporting disc and the outer surface of the through pipe, second filtering pieces are movably connected to the bottom of the supporting disc, the upper portions of the second filtering pieces extend into the through pipe from bottom to top, and after the support rotates relative to the bottom plate, the second filtering pieces can be taken down relative to the supporting disc. According to the filtering device capable of quickly treating sewage blockage,a path of water flow direction from bottom to top is adopted, impurities in sewage difficultly block the second filter screen due to the influence of self gravity, and impurity particles can make contact with the filter screen continuously to be filtered under the upward acting force of sewage flow, and meanwhile, the staying time in the inner pipe is long, so that filtering separation can be fully achieved, and the filtering quality is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a filtering device capable of quickly treating sewage clogging. Background technique [0002] In the process of sewage treatment, the filtration of sewage is an important link. Generally, the filtration of sewage is carried out using a filter screen. The sewage flows through the filter material, and the solid impurities in the water are filtered and separated by the filter material to remove part of the solid impurities in the water. However, the speed of sewage flowing downward under the action of gravity is relatively fast, and the sewage with impurities passing through the filter screen will cause certain damage to the filter screen, and the time for passing through the filter material is too short, making the filtration insufficient. [0003] In order to solve the above problems, this case was born. Contents of the invention [0004] (1) Solved technic...
