Abstract

FIELD: agriculture.

SUBSTANCE: milk separator cleaner is characterized by that in the upper part of the rotor, between the upper bottom and bottom used for fastening of concentric inserts, the chamber is formed, where the non-motile disk with radial canals is located. Concentric inserts from ends are equipped with bilaterial ring protuberances, one of which is faced inside of the concentric insert, while the other - out. On the surface of each concentric insert the space for the collecting of mechanical pollutions is formed.

EFFECT: increase of a degree of cleaning of milk from mechanical contaminations with a density differing from milk density, and with low friction coefficient with reference to surfaces of concentric inserts.

Description

The invention relates to agricultural production and can be used to clean milk from mechanical impurities in the lines of its primary processing and processing.

Known bulkless hermetic milk purifier CM 595R of the Danish company "Titan" (Lipatov N.N. Separation in the dairy industry. M: Food industry, 1971, 400 S., S. 24-26), containing a hollow drum with distribution tubes installed in it for feeding milk into it and a pressure disk of its output after centrifugal cleaning from mechanical impurities.

Its disadvantage is the poor cleaning of milk from small particles of contaminants and the inability to isolate light impurities from it, particles with a specific density less than milk.

Closest to the claimed solution is a multi-chamber clarifying separator with a discharge of the centrate under pressure (Sokolov V.I. Modern industrial centrifuges. Second ed. - Moscow: Mashinostroenie, 1967 - 524 pp., 466-467), the upper part of the rotor of this separator, between the upper bottom and the bottom, which serves for mounting concentric inserts, a chamber is formed in which a fixed disk with radial channels is located.

Its disadvantages are the different speed and duration of the deposition of pollution particles due to the increase in the distance from the center of rotation of the rotor and equal gaps between concentric inserts, as well as the entrainment of already settled contaminants from the surface of concentric inserts.

The objective of the invention is to increase the degree of purification of milk from mechanical impurities with a density different from the density of milk, and having a low coefficient of friction on the surface of concentric inserts.

The problem is solved in that in the milk separator-cleaner in the upper part of the rotor, between the upper bottom and the bottom, which serves to mount the concentric inserts, a chamber is formed in which there is a fixed disk having radial channels, concentric inserts from the ends are equipped with bilateral ring protrusions, one of which is directed into the interior of the concentric insert, the other outward with the formation on the surface of each concentric insert of a mud space to collect mechanical impurities. Concentric inserts are installed with each other in increments gradually decreasing to the periphery of the rotor, and are interconnected by blades in the upper and lower parts of the insert in a single block of rotor inserts. The blades connecting the concentric inserts into a single unit are installed at an acute angle to the axis of rotation of the rotor.

The invention is illustrated by drawings: in Fig. 1 is a diagram of a drum of a separator-milk cleaner, in Fig. 2 is an insert with annular protrusions, in Fig. 3 is a section of annular inserts with vanes in Fig. 1, Fig. 4 is a section of a blade in a concentric insert.

The milk separator-cleaner (Fig. 1) contains a housing 1 and a rotor 2 installed in it, containing a bottom 3, a dispenser for the supplied milk 4, concentric inserts 5 installed in the rotor with a step gradually decreasing to the periphery of the rotor 2 and interconnected into a single unit the upper 6 and lower 7 blades, the rotor cover 8, in the cavity 9 of which the pressure disk 10 of purified milk is fixedly mounted, the shank 11 of which is in the form of a tube connected to the milk feed pipe 12 and has a pipe 13 for discharge under pressure boiled milk from a milk separator.

The rotor 2 is mounted on the shaft 14 of the drive mechanism of the milk-separator separator, and the milk supply pipe 12 is connected to a milk receiving funnel 15. Between the bottom 3 and the cover of the rotor 8 is installed a sealing rubber ring 16.

Each concentric insert 5 (figure 2) of the rotor 2 is equipped with double-sided annular protrusions 17 and 18, respectively, in the upper and lower parts of the insert, with one of the protrusions 19 and 20 directed into the inside of the concentric insert, and the other 21 and 22 outward to form it on the surfaces of each concentric insert of mud spaces 23 and 24 to collect light and heavy particles of contaminants, respectively.

The connection of the concentric inserts 5 into a single unit (Fig. 3) is carried out by blades 6 and 7, which are installed at an acute angle (Fig. 4) to the axis of rotation of the rotor 2 to support milk when it is fed into the cavity between the concentric inserts 5 before cleaning and into the pressure disk 10 after cleaning it.

The separator-milk purifier operates as follows: from the receiving funnel 15 of the milk being cleaned, through the supply pipe 12, it enters the milk dispenser 4 installed in the rotor 2 and then on the bottom 3, where it enters the working area of each concentric insert 5. Under the action of centrifugal forces, the flow of milk, rising between the walls of the concentric inserts 5 under the additional pressure of the lower blades 7, installed at an acute angle to the axis of rotation in the direction of rotation of the rotor 2, is subjected to the action of a centrifugal field. Under its action, particles of milk contaminants are deposited on the walls of concentric inserts 5: on the outside of the lungs and on the inside of heavy impurities, respectively, forming a layer of dirt in the spaces 23 and 24 between the annular protrusions 19 and 21, 20 and 22, and purified milk from concentric inserts 5 enters the upper blades 6 of the block of concentric inserts 5 and under the action of centrifugal force the milk flow is fed into the cavity 9 of the stationary pressure disk 10 and then through the gap between its shank and the supply pipe 12 under pressure In the outlet pipe 13 of the purified milk.

The duration of continuous operation of the separator-cleaner is determined by the amount of dirt on the surfaces of the concentric inserts and the degree of contamination of milk, after which the milk cleaning process is interrupted, the separator-cleaner rotor is disassembled for cleaning from contamination and washing. Further, after assembly, its operation of the separator-cleaner is resumed in the sequence described above.
