Description

Movable sludge balance tank safety stirring device Technical Field The utility model relates to the field of tail water treatment, in particular to a movable type safe stirring device for a sludge balance tank. Background In the production process flow of tail water treatment of a modern water factory, how to keep the sludge concentration of a sludge balance tank uniform and reduce sludge accumulation of the sludge balance tank is an important ring in the tail water flow, and the method is related to the high efficiency of the operation of the sludge balance tank, the rationality of the chemical proportioning and the operation stability of a dehydrator. In the actual production of most water plants at present, the sludge balance tank is easy to generate the phenomenon of accumulated sludge at the corners of the tank body due to the single operation mode of the tank body and the like, frequent cleaning is needed, the operation efficiency of the sludge balance tank is greatly reduced, meanwhile, the sludge concentration in the balance tank is not uniform enough due to the reasons of accumulated sludge, the operation mode of the agitator and the like, the problem of subsequent processes is also easy to occur, and the phenomenon is frequently found in small-size sludge tanks. In the current practical production process, some water plants are provided with push-flow type stirrers in the same sludge pond to solve the problem, although the problems of sludge accumulation and uniformity of sludge concentration are relieved to a certain extent, the maintenance cost and the difficulty are increased, and the push-flow stirrers are required to be installed at the position of the bottom of the pond wall, and meanwhile, auxiliary facilities such as a cable groove, a maintenance well and the like and building structures outside the pond are required to be reserved, so that the push-flow stirrer is not suitable for a small-size sludge pond.
