RU2539951C2 - Milking unit with double-circuit washing system - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to devices for milking cows. The milking unit comprises milking machines, a milk-receiver, a milk pipeline. In the milk pipeline there are terminal devices designed for supplying and stopping of the mechanical cleaners in them. The milking unit additionally comprises a washing machine and a milk pump. The circuit of washing the milk pipelines with mechanical cleaners is separated from the circuit of washing of the milking machines with the washing fluid.

EFFECT: increased efficiency of washing the milking unit.

Description

The invention relates to agriculture, in particular to installations for milking cows.

To maintain the required sanitary and hygienic condition of modern milking machines, they are equipped with milk line washing systems with an injection air inlet, intensifying the speed of the washing liquid [1]. The disadvantages of existing types of plants are the quick cooling of the flushing fluid during circulation flushing, the high cost of detergents and energy.

The closest technical solution (prototype) to the present invention is a milking unit, consisting of milking machines, vacuum wires, looped milk pipelines with milk-vacuum cranes, couplings and milk piping arches; dispensers for group metering of milk; a milk receiver with level sensors controlled by liquid flow distributors and a milk pump with a control unit; a vacuum unit with a vacuum cylinder, vacuum gauge and vacuum regulator; washing devices with a supply collector, washing heads, milking machine holders, a washing pipe with taps, a washing machine with a tank, hot, cold water and circulation valves, a washing concentrate dispenser [2]. The flushing liquid moves as follows: flushing machine → flushing device → milking machines → milk pipelines → controlled liquid flow distributors → milk dispensers → milk collector → milk pump → filter → tank of the washing machine. The disadvantage of such a washing system is the large length of the movement of the washing liquid, especially in linear units, when the length of the milk line is more than 200 meters.

The purpose of the invention is to reduce the washing time, the amount of water and detergents, electricity due to the separation of the washing circuit of milking machines and looped milk pipelines, cleaned mainly mechanically using a minimum amount of washing liquid.

The milking unit comprises a washing machine 1, milking machines 2, a milk pump 3, a milk receiver 4, a milk pipe 6, in which there are end devices 5 for supplying and stopping mechanical cleaners in them.

The proposed installation (see Fig. 1) is characterized in that the milk line is washed separately from the milking circuit with a small amount of water, detergents and the use of mechanical cleaners.

This goal is achieved by the fact that the proposed scheme provides for two washing circuits: milking machines and milk pipelines washed simultaneously, while the milking circuit is washed with washing liquid, and the loop of milk pipelines is cleaned with a mechanical movable device with a minimum consumption of washing liquid.

The technical and economic effect is achieved by reducing the duration of washing, the amount of water, detergents, energy costs for the circulation of the washing solution and improving the quality of milk.
