Sewage primary filtering device

Abstract

The invention belongs to the technical field of riverway cleaning equipment, and particularly relates to a sewage primary filtering device. The sewage primary filtering device comprises a water discharging device, a filtering device and a spraying device, wherein the water discharging device comprises a plurality of sewage discharging pipes; all sewage discharging pipes are connected in series through a plurality of interception tee joints; the tail end of the last interception tee joint is connected with a downward bent bending pipe; the spraying device comprises a water collecting box; a water discharging pipe is inserted and connected into the lower right corner of the water collecting box; a water pump is connected onto the water discharging pipe; the filtering device comprises a mud discharging device, a water collecting plate and a sludge pool; the mud discharging device comprises a filtering box; the filtering box is positioned right under the sewage discharging pipes; the watercollecting plate is suspended right under the filtering box; the sludge pool is positioned at the lower left side of the water collecting plate; the water collecting box is positioned at the right lower side of the water collecting plate. The sewage primary filtering device can solve the problems that in the existing conventional mud-water separation process, the terminal filtering process is relatively slow; the filtering effect is relatively poor; the terminal filtering burden is relatively heavy.

Description

technical field [0001] The invention belongs to the technical field of river channel cleaning equipment, and in particular relates to a sewage preliminary filtering device. Background technique [0002] At present, in the river cleaning construction, after the silt at the bottom of the river is sucked up, the sewage in the discharge pipe is a mud-water mixture. When this part of the mud-water mixture is processed, the mud and water need to be separated to facilitate post-processing and discharge. The muddy water filter device is used at the end to separate the muddy water. Before entering the muddy water filter device, due to the large amount of mud in the muddy water mixture, the terminal filtration process is relatively slow and the filtering effect is poor. Therefore, how to pretreat the muddy water to reduce the burden of terminal filtration is an urgent problem to be solved. Contents of the invention [0003] In view of this, the present invention aims to propose a s...
