Description

Cleaning system for filter cloth of plate-and-frame filter press

Technical Field

The utility model relates to a plate and frame filter-pressing technical field specifically is a cleaning system of plate and frame filter press filter cloth.

Background

Plate-frame filter pressing is a common method for deep dehydration of sludge, solid particles in fluid collide with the wall of a filter cloth hole in the filtering process, the particles are captured and retained by the filter cloth, and are separated from the fluid, so that the aim of solid-liquid separation is achieved, a large amount of calcium, magnesium, iron and aluminum modifying agents are required to be added in the deep dehydration process of the sludge, partial tiny flocs formed by the agents and the sludge are easy to accumulate in pores among filter cloth yarns and gaps among fibers under the action of strong pressure, and meanwhile, because the added coagulant agents exist in hydroxide form during the modifying and flocculating period of the sludge, partial calcium hydroxide substances are easy to react with carbon dioxide in the air to further generate carbonate substances in the contact process with the air, so that the firmness of combination of accumulated substances among filter cloth pores and the filter cloth is enhanced.

After the filter cloth is used for a period of time, grey-white dirt is attached to the surface of the filter cloth, the phenomenon of hardening and hardening occurs, and meanwhile, the dirt is further increased along with the prolonging of the service time, and the dirt is also accumulated in gaps of a water filtering channel of the diaphragm plate. And the washing or back-washing effect is poor, which seriously affects the filtering efficiency of the filter cloth and the normal work of the plate-and-frame filter press. At this time, the filter cloth needs to be removed and cleaned after the filter plate is disassembled. In the stage, the filter cloth is generally soaked in a cleaning pool, stirred by a stirrer, taken out, washed by a high-pressure water gun and finally dried. However, a large amount of filter cloth is generally soaked in the cleaning tank, and the filter cloth layers are laminated together, so that the soaking and cleaning effect is poor, and partial impurities remained after passing through the soaking tank are still difficult to be washed and removed by a high-pressure water gun, thereby affecting the cleaning effect of the filter cloth.
