Description

The invention relates to agriculture, in particular to the washing of milking machines.

A device for washing and disinfecting milking equipment is known, including a bath, an evacuator, a pulsator with a pulsator, a collector tube, a vacuum wire and a milk conduit providing circulation washing and disinfection of milking equipment, in which the pulsoar amplifier when switching cans provides pulsation of the washing liquid [1] .

The disadvantages of the known installation for washing and disinfecting the dolina are: the impossibility of washing all parts of the milking units with milk lines, the separate execution of the pulsator and pulsous booster complicates and increases the cost of the design of the washing device.

Also known installation for washing the milking equipment adopted for the prototype, including a bath with washing liquid, vacuum pipe, pulsator with inlet and outlet nozzles and located in it a flow interrupter of washing liquid. This installation is intended for washing only the milking machines (without milk pipe, milk collector, cooler) with a pulsating flow of washing liquid [2].

The disadvantage of this technical solution is that it does not provide for the adjustment of the parameters of flow pulsation, which does not allow to optimize the washing process.

The next technical solution is a device for circulating washing of milk lines of milking machines, containing a milk line with cranes for connecting milking machines, an air separator, a washing device, a centrifugal pump for pumping liquid from the air separator, which is connected to a vacuum pump through a branch pipe. The flushing device is connected to the end of the milk line, remote from the air separator, with a hose having an opening for air suction [3].

The main disadvantage of this device is the inability to ensure the supply of air volume necessary to create a cork mode of flow of the washing liquid in the milk lines, which prevents the creation of optimal conditions for maximum washing effect.

The prototype is a device for washing milking lines of milking machines, containing a tank, a liquid line connected with it, a gas line to provide liquid supply and a gas-liquid flow, a gas-liquid flow line, a gas supply pulsator installed in the gas line, a pulsator and the atmospheric air interrupter, connected in series with the gas supply pulsator [4].

The disadvantages of the prototype are: low quality of washing of milk lines with increased diameter of modern milking machines due to the lack of turbulent movement of the washing liquid, as well as violation of the cork mode of the washing liquid through the milk line.

The objective of the invention is to eliminate these disadvantages.

The technical result is an increase in the efficiency of washing the milk lines of an increased diameter of modern milking machines, by ensuring the creation of a turbulent flow regime of washing liquid.

This technical result is achieved by the fact that in the device for washing the milk lines of milking machines, containing a tank, a liquid line connected to it, a gas line to provide liquid supply and formation of a gas-liquid flow, a line of gas-liquid flow diversion according to the invention is equipped with rigidly fixed hollow nozzles placed on its outer surface along a helical line through each angle of rotation of 90 ° and set at an angle of 30 ° to the direction The flow of washing fluid flows along the longitudinal axis of the fluid line, with one end of each hollow nozzle installed in a hole made on the surface of the milk supply line, and the other end connected to the inlet of the supply air channel with a tap, each hollow nozzle made in the form of a truncated cone whose diameter from the side of the air channel is larger than the diameter located in the area of the opening on the surface of the milk line.

A device for washing milk lines of milking machines is illustrated by the diagrams:

FIG. 1 - scheme of washing milking lines of milking machines;

FIG. 2 is a cross-sectional diagram of a milk pipe with a nozzle;

FIG. 3 is a diagram of a longitudinal section of a milk pipeline with a nozzle;

FIG. 4 shows the layout of the nozzles on the surface of the milk line.

A device for washing milking lines of milking machines comprises a tank 1 (FIG. 1), a liquid line connected with it, a gas line for providing liquid supply and formation of a gas-liquid flow, a line for diverting a gas-liquid flow. The liquid line includes a milk pipe 2 connected to the tank 1, and a flushing pipe 3, onto which milking machines 4 are installed. The flushing pipe 3 is connected to a washing tub 5. The gas-liquid flow branch line 6 connects the tank 1 with a volumetric pump 7, drain pipe 8, which is located above the washing tub 5. The gas pipeline includes a vacuum wire 9 connected to a vacuum pump 10, a vacuum balloon 11 and a vacuum gauge 12.

In addition, the liquid line of the milk pipe 2 is equipped with rigidly fixed hollow nozzles 13 (FIGS. 2, 3 and 4) placed on its outer surface along a helix through each 90 ° rotation angle and set at an angle of 30 ° to the direction of flow of the washing fluid through the longitudinal axis of the fluid line. Moreover, one end of each hollow nozzle 13 is installed in the hole 14, made on the surface of the main line of the milk pipeline, and the other end is connected through pipe 15 of the supply air channel 16, with a crane 17. Each hollow nozzle 13 is made in the form of a truncated cone 18, the diameter D of which from the side of the air channel 16 is larger than the diameter d located in the zone of the hole 14 on the surface of the milk line main.

A device for washing the milk lines of milking machines works as follows.

When air is sucked out by a vacuum pump 10, a vacuum is created in the system (Fig. 1), under the action of which the washing liquid from the washing tank 5 is sucked into the flushing pipe 3 and further, passing through the milking units 4 and the milk line 2, enters the tank 1. From tank 1 the liquid is pumped through pipe 6 by a volumetric pump 7 into the wash tub 5.

During the flushing process, a tap opens to supply air to the milk duct through the air duct. Air through the air channel through the nozzles and nozzles is fed into the milk conduit. Due to the performance of the nozzles in the form of a truncated cone, the velocity of the supplied air in the zone of each hole increases and, due to their location along a helical line on the surface of the milk conduit, creates a turbulent flow of washing liquid. Also installation of the nozzles at an angle of 30 ° to the direction of flow of the washing liquid along the longitudinal axis of the fluid line allows the acceleration of the moving flow of washing liquid and generally performs the given process qualitatively.

Thus, the proposed device for washing the milk lines of milking machines allows to increase the efficiency of washing by providing a turbulent flow of washing liquid and gas.
