SU718124A1 - Bulk filter - Google Patents

Description

The invention relates to the field of filtration, namely to bulk filters intended for the purification of liquids containing floating sludge n colloidal additives, in particular, copper electrolytes, and can be applied in the chemical, hydrometallurgical and other industries.

A bulk filter for cleaning is known, a fluid comprising a housing with a lid, a drainage base with a filter charge placed thereon, and nozzles for supplying a drainage liquid 1.

. The disadvantage of the filter is that the top layer of the filter charge is very quickly clogged with colloidal inclusions, which causes the filter performance to drop sharply with time and the filtration process cycle is very short.

This disadvantage is partially eliminated in the filter equipped with a paddle device 2.

However, in the known filter, the paddle device loosens a very thick layer

filter load, which leads to deeper penetration of colloidal inclusions into the filter layer and worsens the conditions of its regeneration.

The aim of the invention is to increase the filter capacity.

This goal is achieved by the fact that, in the filter we offer, the paddle device is equipped with chains fixed at one end on the crossbar, at a distance of 1 1 each.

The filter consists of a housing / with lower and upper lids 2. In the filter filter, there is a drainage bottom 3 with filtering load 4.

The trunk mechanism is driven by a rotational drive 10. For D1 (the hydraulic fluid to be filtered is installed branch pipes // and 12, and for the supply of wash water and removal of the suspension - branch pipes 13 and 14.

The filtered solution is passed through a pipe // through a filtering layer and discharged through pipe 12. During the filtration process, the accumulated gaps in the upper filtrating layer and colloidal additives by chain strokes 6 are reworked 1c, eliminating blockage of filter pores.
