Description

The utility model relates to the field of media separation, namely to removable cartridge filters for purifying liquids for food and technical purposes from mechanical contaminants, protein sediment, suspension, and fine impurities.

A known filter unit contains a cylindrical housing with an inlet pipe, the sides of the housing are hermetically sealed with removable covers, one of which is equipped with an outlet pipe and a filter for ultra-fine liquid purification (RU Patent No. 2619639 dated May 17, 2017), which ensures filtration of the liquid from mechanical impurities and suspended matter. . At the same time, it does not provide purification of the liquid from fine impurities, the high content of which leads to a decrease in the quality of the liquid, namely turbidity, a reduction in shelf life in food liquids, and in technical liquids - equipment breakdown.

The technical problem is to eliminate the noted shortcomings and improve the quality of liquids.

The technical result consists in a significant reduction of not only mechanical impurities, viscous components, suspension, but also fine impurities.

The technical problem is eliminated by structuring the filter unit for purifying liquids for food and technical purposes:

a cylindrical body with an inlet pipe, the sides of the body are hermetically sealed with removable covers, one of which is equipped with an outlet pipe;

an external polypropylene filter with a thickness of 1 cm and a cell of 5 microns, retaining mechanical contaminants from 5 microns;

-middle layer, which is represented by a bulk sorbing layer 1.5 cm thick, characterized by dynamic absorption capacity, responsible for lightening, and in some cases, discoloration of drinks and oil refining;

an internal polypropylene filter with a thickness of 1 cm and a cell of 1 micron, eliminating protein sediment, suspensions, fine impurities and sorbent residues. For tightness, the filter elements of the block are equipped with silicone plugs on both sides.

The drawing shows a cross section of the filter block.

The filter block contains a cylindrical housing 1 with an inlet pipe 2. On the sides, the housing 1 is hermetically sealed with removable covers 3 and 4. The cover 3 is equipped with an outlet pipe 5. Inside, the filter block contains an external polypropylene filter 6 with a thickness of 1 cm and a cell of 5 μm, a layer of bulk sorbent material 7 1.5 cm thick and an inner layer 8, which is a polypropylene filter 1 cm thick and a cell of 1 µm. The filter elements of the block are equipped with silicone plugs 9 and 10 on both sides.

The inventive filter unit combines three levels of purification in one housing.

At the 1st level of filtration (polypropylene filter), fine cleaning from mechanical impurities occurs.

At the 2nd level of filtration (layer of bulk sorbent material), chemical absorption of liquids occurs, characterized by dynamic absorption capacity, which is responsible for clarification, and in some cases, discoloration of drinks and oil refining.

At the 3rd level of filtration (polypropylene filter), protein sediment, suspended matter, fine impurities and sorbent residues are removed.

The gap between the housing and the outer filter element is 0.5-0.7 cm, which ensures the most complete supply of liquid along the entire perimeter of the filter surfaces.

Polypropylene filter elements are made in white color, the contamination of which during use serves as a visual indicator that allows you to assess the amount of mechanical impurities, sediment, and suspension.

Bulk sorbent material is selected from those known from the prior art, depending on the type of liquid and the tasks facing the filter user.

Replacement and installation of new filter elements is carried out through a removable cover, which significantly reduces the time for changing filter elements. When changing, the entire filter unit is discarded.
