Problems solved by technology

[0003] The high-pressure washing nozzles of the filter cloth of the existing rotary disc filter are all fixed, with high water pressure and high filter cloth washing efficiency, but each nozzle can only wash the solid materials in its own specific area and cannot be moved
In actual production, if the flushing water contains large particles of impurities, individual nozzles will be blocked, and when the angle of the nozzles deviates, the water pressure will weaken at the joint between the two nozzles. The above two situations will cause some Incomplete flushing of the filter cloth in the area will cause the mesh of the filter cloth in this area to gradually become dead, the filtration efficiency of the filter cloth will decrease, and the active ingredients taken away from the solid material will increase.

Abstract

The invention discloses a movable type filter cloth cleaning device of a rotary disc filter. The device mainly comprises a movable apparatus which is provided with several nozzles, wherein the nozzles are connected to a nozzle main water pipe by flexible pipes; the movable apparatus is placed on a guide rail which is fixed above a filter rotary disc, and the length of the guide rail is longer than radius of filter disc sector of the filter; reciprocating motion of the nozzles is driven by free movement of the movable apparatus on the guide rail, so that completely covering type cleaning of a piece of filter cloth is realized; a pipeline for adding sulfuric acid is connected to the nozzle main water pipe, a stop valve is used for controlling adding opportunity and addition of sulfuric acid, so that cleaning efficiency of the filter cloth is further improved; frequencies of production halts and filter cloth cleaning are reduced, service life of the filter cloth is prolonged, production capacity of the apparatus is improved, and working strength of laborer is reduced.

Description

technical field [0001] The invention belongs to the technical field of industrial filtration, in particular to a mobile filter cloth cleaning device for a turntable filter. Background technique [0002] The working principle of the rotary disc filter is mainly to use vacuum equipment to form a negative pressure inside the filter, and transport the solid-liquid mixture generated by physical, chemical or physical chemical reactions to the filter disc of the filter, and pass through the polypropylene material with a specific mesh number. After the filter cloth is separated from solid and liquid, the filtrate is recovered through the infusion pipe, and the solid material is transferred to the unloading area with the turntable; in order to prevent the filter cloth from being scratched, the material with a thickness ≥ 2mm is usually unloaded by the screw device first, and then the thickness is removed. Materials < 2mm are flushed and removed by high-pressure nozzles. [0003] ...
