Abstract

SUMMARY OF THE INVENTION: A filter charge for coarse cleaning is located in a filter housing, sandwiched between perforated baffles that divide the housing into a lower distribution chamber and an upper settling chamber. In the load placed glasses, the edges of which are located in the settling chamber. The glasses are equipped with filters for fine cleaning. 1 s.p.f., 2 ill.

Description

The invention relates to filtering and can be used in the food industry and in particular in its wine industry.

The purpose of the invention is to improve the quality of cleaning liquids and the filter life by providing two-stage pre-filtering before the fine filter elements, which will improve the quality of cleaning and increase the filter life by at least 3 times.

In Fig.1 shows a filter for cleaning liquids in section, in Fig.2 node I.

The filter for cleaning liquids comprises a housing 1 with a cover 2, an upper 3 and a lower 4 perforated partitions, between which a load 5 of granular material is placed, dividing the housing 1 into the lower distribution chamber 6 and the upper settling chamber 7. In the load 5 placed glasses 8, the edges 9 of which are located in the settling chamber 7. Filtering elements of fine cleaning 10 are installed in the glasses 8 and are made in the form of porous plates 11 with a central

hole 12, in which there is a pipe 13 with openings 14 for removing the filter and peripherally connected frames 15 with holes 16 for passing the cleaned liquid into the odd gaps 17 and internal frames 18 with holes 19 for removing the filter from the even gaps 10 between the plates eleven.

A nozzle 21 for supplying a liquid to be cleaned, a nozzle 22 of the filtrate outlet and a nozzle from the outlet of the washing liquid are located on the housing 1. On the cover 2 there is a flushing fluid supply pipe 24 and an air outlet pipe 25.

The filter works as follows.

The cleaned liquid through the pipe 21 is fed into the distribution chamber 6, and then into the granular charge. The passage through the loading liquid is cleaned of suspended particles and protective colloids and enters the upper settling chamber 7, where particles passing through the partition 3 are deposited in front of the edges 9 of the glasses 8. Next, the liquid enters the fine filter elements 10 installed in

glasses 8. The passage through the Porous plates 11, the liquid finally clarifies and through the holes 14 it enters the cavity of the pipe 13 to drain the filtrate and is discharged through the pipe 22 into the finished product pipe.

During regeneration, the septum 3 is raised, washing liquid is supplied through the pipe 24, which is then discharged through the pipe 22.

Claims (2)

SUMMARY OF THE INVENTION 1. A filter for cleaning liquids, comprising a housing with a cover and inlet and outlet nozzles, a granular filter charge for pre-cleaning and filter elements for fine cleaning, characterized in that, in order to increase the resource and quality of cleaning liquids, it is provided horizontal perforated partitions between which the load is located, dividing the housing into the lower distribution and upper settling chambers, and placed in the loading cups, the edges of which are located in the settling chamber, and filter elements are installed in the cups. 2. The filter according to claim 1, characterized in that the filter elements are made in the form of porous plates with a central hole, in which there is a pipe with holes for draining the filtrate, connected at the periphery by frames with holes for passage of the liquid to be cleaned into even gaps and internal frames with holes for draining the filtrate from the odd gaps between the plates. 24 25 2 FIG. 2
