Description

The utility model relates to devices for filtering milk and can be used on farms and in the dairy industry.

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 of the sump freely connected to the receiver. 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 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.

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

The closest known technical solution is 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 internal

a filter element mounted with an annular gap relative to the housing, characterized in that it is provided with a fixing adapter for mounting the filter element in the housing and a removal adapter for changing the filter element, the fixing adapter for mounting the filter element in the housing is made in the form of a first sleeve mounted on said a 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 de 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 screw thread for connection with a cover having an internal screw thread and external processes for unscrewing, and the filter element is made in 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 radially suspended diffuser channels. / RU 53585, U1, 05.27.2006 /.

Disadvantages: the inlet pipe is perpendicular to the tangent circumference of the housing, which leads to the fact that the milk flow is directed frontally to the surface of the filter element and 10-15% of the total surface is used, the pore size of the filter element is not dependent on the filtered liquid, the filter does not equipped with a gasket, which can lead to a deterioration in the quality of filtration due to overflow of unfiltered milk, the lower guide in the form of a solid cylinder, which leads to the fact that after filtration into the body e is milk.

EFFECT: increased efficiency of milk purification, decreased bacterial contamination of milk, reduced milk losses during filtration.

The technical result is achieved by using a milk filter consisting of a housing with six rods in the upper part for fixing the lid, a lid 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 the mating parts, the inlet pipe, which is tangential to the body, the outlet pipe, the upper guide in the form of 4 bent and welded to the cover rods of stainless steel and arranged relative 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 screws for fixing the cover.

Statics.

Case 1 is made of stainless steel, approved in the food industry. At the top there are six threaded rods for fixing the cover.

Cover 2 serves to install and replace the filter element. There are six holes in the lid for the passage of rods fixing the lid.

Filter element 3, made by air blowing from food grade polypropylene. The density of the filter element is variable, while the pore size is 30-50 microns, which makes it possible to increase the grade of milk by 1-2 grades after filtration, depending on the initial contamination, and also to reduce the bacterial contamination of milk. The fat content of milk at a given pore size does not decrease, and somatic cells and mechanical impurities are retained. The capacity of the filter element is up to 70,000 liters.

Gaskets 4 made of food rubber, are used to eliminate gaps between the mating parts.

The inlet pipe 5 is welded tangentially to the body. This allows you to create a centrifugal force inside the housing when milk is received. Heavy mechanical impurities beat off to the walls of the body, remain at the bottom and walls of the body. In addition, the location of the inlet pipe tangentially to the housing contributes to the uniform use of the filter element. This design of the inlet pipe improves the quality of milk purification in comparison with the prototype.

The outlet pipe 6 is located in the lower part of the housing.

The upper guide 7 is 4 stainless steel bent and welded to the lid of the bar. To each other, they are at an angle of 90 °.

The lower guide 8 is 4 stainless steel bent and welded to the bottom of the body of the bar. To each other, they are at an angle of 90 °. This design allows you to completely drain the milk from the filter housing.

The cover is equipped with a handle 9 for ease of removal from the housing.

Nuts 10 are used to seal the fastening of the cover to the housing.

Dynamics.

A filter element 3 is installed in the housing 1. Between the lid 2 and the housing 1, the lid 2 and the filter element 3, gaskets are installed 4. The housing 1 is closed by a lid 2, which is tightly attracted by the nuts 10. Milk enters under pressure 5 into the inlet pipe, while in the housing The filter generates a centrifugal force, which deposits heavy mechanical impurities on the walls and bottom of the vessel. Milk passes through the filter element 3 from the outer cavity into the inner one. Due to the variable density of the filter element, mechanical impurities are distributed throughout the thickness

filter element from large sizes on the outer surface to smaller ones on the inside. From the internal cavity, through the pipe, milk in purified form is discharged into the receiving pipe.

A filter of this design can be used in large milk processing complexes, for example, at collection points and dairy plants.

When filtering smaller volumes of milk, a milk filter with a modified lid and guide design can be used. These changes are due to the smaller size of the filter itself.

The milk filter consists of a housing with a thread in the upper part for fixing the lid, a lid with a threaded connection in the upper part, a filter element with a variable density and pore size of 30-50 μm, food rubber gaskets to eliminate gaps between the mating parts, an inlet pipe located along a tangent to the body, the outlet pipe, the upper guide in the form of an equal-sided trapezoid, the lower guide, in the form of a stainless steel bar bent and welded to the bottom of the body.

Dynamics.

A filter element 3 is installed in the housing 1. A gasket 4 is installed between the cover 2 and the housing 1. The housing 1 is closed by a cover 2, which is screwed in thread. Milk flows under pressure into the inlet pipe 5, while a centrifugal force arises in the filter housing, which deposits heavy mechanical impurities on the walls and bottom of the vessel. Milk passes through the filter element 3 from the outer cavity into the inner one. Due to the variable density of the filter element, mechanical impurities are distributed over the entire thickness of the filter element from large sizes on the outer surface to smaller ones on the inside. From the internal cavity, through the pipe 6, the milk in purified form is discharged into the receiving pipe.

The filter of this design can be used directly in dairy farms.
