Layered filter device and method for sludge treatment

Abstract

The invention discloses a layered filter device and method for sludge treatment. The device comprises a tank body, footings, a motor base and a pump base, wherein the bottom legs are arranged at the bottom surface of the tank body, a liquid outlet tube is arranged beside the footings, an electromagnetic valve is arranged outside the middle of the liquid outlet tube, and a flow sensor is arranged on the side surface in the liquid outlet tube. The layered filter device has the beneficial effects that a servo motor drives a mixing roller to rotate so as to accelerate sludge filtering progress; the flow sensor can acquire discharge capacity of the filtered water in real time and a display screen displays the discharge capacity in real time, so that a user can observe and perform statistics analysis conveniently; the sludge filtering progress in the tank body can be known in real time through an infrared camera and can be shown on the display screen in real time, so that the user can control the sludge filtering progress accurately; a hydraulic pump drives a scraper to move transversely so as to push out filtered sludge through a drainage pipe, so that an automatic drainage function isrealized, and the device can be promoted and used more extensively.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a layered filter device and method for sludge treatment. Background technique [0002] Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. The higher the degree of wastewater treatment, the more sludge residues are generated that need to be disposed of. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complicated and costly part of the operation of the sewage treatment system. When treating sludge, it is often necessary to use filter devices to remove the water in the sludge Filter out to reduce the water content of the sludge and facilitate subsequent treatment. [0003] However, under traditional circumstances, the layered filtrat...

Problems solved by technology

[0003] However, under traditional circumstances, the layered filtration device cannot count the discharge of filtered water in real time, and at the same time cannot check the progress of sludge filtration in real time, so that it is impossible to accurately grasp the progress of sludge filtration, and it is prone to incomplete filtration. At the same time, it is impossible to realize Automatic sewage
