Description

The utility model relates to devices for filtering milk and can be used on farms and in the dairy industry. More specifically, the filter is intended for filtering milk at dairy plants and dairy farms.

Known milk filter containing a milk receiver with located at different levels of the inlet and outlet pipe and equipped with a coarse filter located between the pipes. The lower part of the receiver housing has a conical shape and is equipped with a conical plug with a rod resting on the bottom, freely attached to the receiver of the sedimentation tank. The receiver by means of an outlet pipe is connected to a fine-cleaning housing having a cylindrical chamber with a longitudinal side slit and an outlet pipe. Inside the housing there is a filter element mounted on the outer surface of the squirrel wheel having ribs on the inner surface. The lower part of the squirrel wheel is made in the form of a piston with a tail, the side surface of which is provided with a helical surface with a large angle of elevation. A nut is mounted on the shank. In the lower part of the housing there is a support sleeve with guide holes. The squirrel wheel and nut are spring-loaded, respectively, by springs. The bottom of the housing has a drain (patent RU 2115306).

Disadvantages: the complexity of the design and manufacture, separate elements for coarse and fine filtration.

A device for filtering food liquids, mainly milk, containing a vertical cylindrical body having an inlet pipe in the lateral cylindrical surface, the lower end of which is made in the form of a disk with a central hole, under which the outlet pipe is placed, and the upper end is closed by a lid, and an internal filter element installed with an annular gap relative to the housing, characterized in that it is equipped with a fixing adapter for mounting the filter element in the housing and removing hell pter to change the filter element, and the fixing adapter for mounting the filter element in the housing is made in the form of a first sleeve mounted on the said disk above its hole with the possibility of landing fastening on it one end of the filter element, and the removal adapter for changing the filter element is made in the form of a second sleeve fixed in the center of the inner surface of the cover with the possibility of landing fastening on it the second end of the filter element, while the upper end of the housing is provided with an external th screw thread for connection with a cover having an internal screw thread and external processes for unscrewing, and the filter element is made in the form of a tubular cartridge made of food-grade polymer material, for example, food-grade polypropylene, with pore sizes radially decreasing from the periphery to the center, forming radial diffuser channels (patent RU 53585U).

The disadvantage of this solution is the cumbersome design and many details. The closest analogue is a milk filter (patent RU 72150U), which contains a housing with six rods in the upper part for fixing the cover, a cover with six holes for passing its fixing rods, a filter element with a variable density and pore size of 30-50 microns, three gaskets made of food rubber to eliminate gaps between mating parts, an inlet pipe located tangentially to the body, a discharge pipe, an upper guide in the form of 4 bent and welded stainless steel rods to the cover, arranged positions with respect to each other at an angle of 90 °, the lower guide 4 as a bent and welded to the arranged relative to each other the bottom housing of stainless steel bars at 90 °, six nuts for fixing the cover. To filter smaller volumes of milk, a filter can be used, characterized in that the casing has a thread in the upper part, the lid has a thread on the inside, is equipped with a food-grade rubber gasket installed between the filtering element, the casing and the lid, the upper guide is made in the form of an isosceles trapezoid, and lower guide in the form of a stainless steel bar bent and welded to the bottom of the body. The disadvantage of this solution is the cumbersome design and many details.

Effect: simplify the design of the filter.

The claimed technical result is achieved due to the fact that the milk filter, consisting of a housing, a refillable filter cartridge, characterized in that the filter is made with the possibility of mounting directly on the pipeline by attaching to it with connecting nuts, and the filter cartridge is fixed with a housing connector nut.

In addition, the filter cartridge is made of woven mesh made of food-grade stainless steel.

Brief Description of the Drawings

In FIG. the design device of the milk filter is shown (a - direct-flow milk filter, 6 - angular milk filter), where 1 - Housing, 2 - Cartridge, 3 - Connecting nut, 4 - Housing connector nut.

Utility Model Implementation

The milk filter can be implemented in two types: direct-flow (see Fig. (A)) and angular designs (see Fig. (B)). To clean highly contaminated milk, it is advisable to use an angle filter, since it makes it possible to mechanically wash the cartridge without disassembling the pipelines. The actual filter capacity is determined by the quality of the original product. The filter can be made of stainless steel, for example, of stainless steel grade 12X18H10T according to GOST 5632-72 or similar stainless steel grades that meet the requirements of GN 2.3.3.972.

The filter, according to Fig., Consists of a housing 1, a refillable cartridge 2, connecting nuts 3, a nut of the housing connector 4.

Cartridge 2 can be made of woven mesh made of food grade stainless steel. The filter fineness is determined by the mesh size of the filter mesh, and the throughput is the mesh area.

The principle of operation of the filter is as follows: milk is pumped into the filter housing 1 to the refillable cartridge 2, on which particles of contaminants settle, then the milk leaves the filter purified.

The direction of the filter flow is from the outside to the inside, and the cartridge is flushed with a reverse flow of clean tap water after mechanical removal of the visible fraction of contaminants from its surface.

To replace the cartridge 2, unscrew the nut of the housing 4 connector and remove the cartridge. The filter is mounted directly on the pipeline. The pipeline is connected to the filter using connecting nuts 3.

The filter is sanitized by countercurrent of the washing liquid or by mechanical cleaning of the mesh of the cartridge removed from the filter housing, which can significantly simplify the filter processing process and simplify its design.

Simplification of the design of the filter is achieved due to the fact that all elements inside the filter housing, except for the filter element, are excluded from the filter.
