Sludge discharge device for sewage treatment and use method

Abstract

The invention discloses a sludge discharge device for sewage treatment and a use method. The sludge discharge device comprises a cabin cylinder, power cabins are welded at two ends of the cabin cylinder, driving motors are mounted in the power cabins, the driving motors extend to the outside of the power cabins and are provided with paddles, protective covers are mounted on the outer surfaces of the power cabins, a sludge pump is installed at one end in the cabin cylinder, the input end of the sludge pump is provided with the output end of a first electric control valve, and the input end of the first electric control valve communicates with an input pipe. Sludge discharge treatment is performed in a submersible sludge suction manner, and compared with the prior art, a sludge bucket and a sludge discharge pipe do not need to be matched for each horizontal-flow sedimentation tank, so that the workload is greatly reduced, after sludge discharge is completed, only each sludge discharge device needs to be fished, and treated sludge solids are directly taken out from the interior of a cabin body after being fished, and can be directly transported and subjected to subsequent treatment. Meanwhile, the sludge discharge device does not need to be placed in water for a long time and can be regularly maintained, so that the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge discharge device for sewage treatment and a use method thereof. Background technique [0002] The advection sedimentation tank consists of three parts: the inlet and outlet, the water flow part and the sludge bucket. The plane of the pool body is rectangular, and the inlet and outlet are respectively set at both ends of the pool. The inlet generally adopts the submerged water inlet hole, and the water flows into the pool body through the evenly distributed water inlet holes from the inlet channel. There is a baffle behind the water inlet hole to make the water flow Evenly distributed across the entire width of the pool; overflow weirs are often used at the outlet to ensure that the clarified water after sedimentation can flow into the outlet channel evenly along the width of the pool. A scum tank and a baffle are arranged in front of the weir to intercept the s...

Problems solved by technology

[0003] However, the advection sedimentation tank is used for mud discharge. In the prior art, mud hoppers and mud discharge pipes are used to discharge mud. As a result, each mud hopper needs to be equipped with a separate mud discharge pipe for mud discharge. The workload of mud discharge is large, and the use of Mechanical mud discharge also leads to long-term immersion of machinery equipment and driving parts in water, causing rust problems in equipment parts
