A sludge removal system

Abstract

The invention discloses a mud discharge system, which belongs to the technical field of sedimentation tanks. Including the driving mechanism and the mud discharge mechanism, the mud discharge mechanism includes a bottom plate, a back plate, a side plate, a partition and a mud discharge pipe, the bottom plate is connected to the back plate, and there are two side plates on both sides of the bottom plate and the back plate There is a partition in between, the partition is fixed on the bottom and back, the partition and the side are triangular prisms, there are mud scrapers on the sides of the bottom and side, there are mud guards on the top of the back, and a mud discharge pipe Through the partition, there is a vertical pipe on the mud discharge pipe, the mud discharge hose is connected to the vertical pipe, and the mud discharge hose is connected to the mud discharge pipe. There are pulleys on the side of the side plate, and a pulley on the lower part of the side of the back plate. The driving mechanism includes: Fixed pulley, stay rope and sleeve. There are fixed pulley and sleeve on the side wall of the sedimentation tank. Two stay ropes are respectively fixed to the mud discharge mechanism. The stay rope passes through the fixed pulley and sleeve and is placed on the top of the sedimentation tank. The invention occupies less space in the mud accumulation area, reduces the number of mud discharge operations, and improves the hydraulic mud discharge conditions of perforation.

Description

technical field [0001] The invention relates to a mud discharge system of an inclined plate sedimentation tank, in particular to a mud discharge system suitable for an inclined plate sedimentation test device. Background technique [0002] There is a very shallow sedimentation tank between every two parallel inclined plates in the inclined plate sedimentation tank. Make the treated water and the settled sludge move and separate in the shallow sedimentation layer. The inclined plate sedimentation tank uses the principle of "shallow sedimentation" to shorten the sedimentation distance of particles, thereby shortening the sedimentation time, and increasing the sedimentation area of ​​the sedimentation tank, thereby improving the treatment efficiency and reducing the floor space, so it is widely used. Because of its simple structure and convenient operation, the perforated mud discharge pipe is often used as the mud discharge system of the inclined plate sedimentation tank. Ho...

Problems solved by technology

However, in the mud accumulation area of ​​the sedimentation tank, there is an inclined platform surrounded by a V-shaped mud accumulation tank, which occupies a large amount of space in the mud accumulation area, reduces the space for storing mud in the mud accumulation area, and increases the number of mud discharges; in addition , the perforated mud discharge pipe is provided with a large number of mud discharge holes along the direction of the mud accumulation tank, so that the hydraulic conditions between the mud discharge holes are greatly different, resulting in the blockage of the mud discharge holes, and the mud accumulation in some areas of the mud accumulation area cannot be smoothly For discharge, the inclined plate needs to be disassembled, and the mud accumulation cannot be removed by cleaning
