Description

FILTER CLOTH WASHING DEVICE OF BELT PRESS}

The present invention relates to a filter cloth washing apparatus for a belt press, and more particularly, a brush rotatably installed in a washing box containing washing water is installed at a lower part of the filter cloth, and the lower part is locked in the washing water and the upper part is not locked. In addition, the filter cloth pressure roller installed with the lower part submerged in the wash water is installed to be in close contact with the upper part of the filter cloth from the upper part, and saves water and energy by intermittently replacing only the washing water in the washing box without using a high-pressure pump and nozzle. Sludge and chemical components attached to the surface of the conveyed filter cloth can not only wash the filter cloth by the brush, but also to prevent the noise and odor caused by the nozzle injection of high-pressure wash water, will be.

In general, the sludge separated from the waste water is introduced into the sludge agitation tank together with the polymer flocculant and reacted to form a suitable floc for dewatering. Then, the sludge is transported to the dehydration part evenly distributed on the sludge transporting lower filter bag through the quick chute of the dehydrator. Let's do it.

Thereafter, the upper filter cloth is covered from a certain section, and the sludge is wound around the roller of the pressurization step by the tension of the upper and lower filter cloth to discharge the treated separation water contained in the sludge, and the dehydrated cake is discharged to the rear end of the apparatus.

Sludge remains in the form of small particles in the mesh-shaped eye neck of the upper and lower filter cloths in the above-described treatment process, and the upper and lower filter cloth cleaning devices are installed at predetermined positions on the running path of the upper and lower filter cloths.
