Abstract

FIELD: agriculture. SUBSTANCE: washing apparatus has tank 1, milk pipeline 3 with milk claw 4, vacuum pipeline 3 with pulsator 6 positioned between vacuum pumps and milk claw 4 and provided with inlet branch pipe 7 and outlet branch pipe 8, washing liquid cutoff device positioned in it for defining constant vacuum chamber and variable vacuum chamber. Washing liquid cutoff device has spring-loaded piston 9. Branch pipes 7 and 8 are periodically communicated and disconnected one from another by piston 9 to provide periodical suction of washing liquid from tank 1. As a result, pulsed motion is transmitted to washing liquid, that flows through milk tracts of milking unit. Washing liquid flow pulsation frequency and volume of liquid sucked during one cycle are adjusted by screw. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 2 dwg

Description

 The invention relates to agriculture, and specifically to equipment for washing milking installations. It can be used in devices for the preparation of electroactivated solutions as a regulator of the exposure of electrolysis.

A known system for washing a milking unit, consisting of a milk line, a vacuum unit with a vacuum wire, an air separator (milk collector), a device for pumping liquid, a cooler, a washing device and milking machines [1]
The system allows you to flush all parts of the milking unit in contact with milk. However, it does not provide for pulsation of the washing liquid in the milk ducts, which reduces the washing efficiency.

 There is also known an installation for washing and disinfecting milking equipment [2] including a bathtub, a defoamer, a pulse amplifier with a pulsator, a collector tube, a vacuum wire and milk-wire, which provides circulating washing and disinfection of the milking equipment, in which the pulse amplifier also ensures flow pulsation when switching the tanks washing liquid. To drive the pulse amplifier in this installation, a pulsator [4] is used containing a housing, a membrane, a valve, a regulating device, and four chambers.

 However, this installation is not designed to flush all parts of milking units with milk pipelines. In addition, the separate design of the pulsator and the pulse amplifier complicates and increases the cost of the design of the washing device.

 In addition, there is a known installation for washing milking equipment [3] adopted as a prototype, including a bath with washing liquid, a vacuum pipe, a pulsator with inlet and outlet nozzles and a washing fluid flow interrupt located therein. The specified installation is intended for washing only milking machines (without milk line, milk collector, cooler) with a pulsating flow of washing liquid.

 However, it does not provide for adjustment of flow pulsation parameters, which does not allow to optimize the washing process.

 In FIG. 1 schematically shows a milking machine in a washing mode; in FIG. 2 pulsator with a chopper.

 A device for washing milking installations contains a bath for washing liquid 1, a collector pipe 2, milk line 3 with a milk collector (air separator) 4, a vacuum wire 5 and a pulsator 6 with inlet 7 and 8 outlet pipes and a flow breaker placed in it, installed in its cut made in the form of a spring-loaded piston 9, which rests on a spring 10 installed in the pulsator housing 11 and separates the constant vacuum chamber 12 from the variable vacuum chamber 13. The membrane 14 separates the chamber 13 from the constant vacuum chamber 15 pulse atora. The valve 16 is supported by a valve 16 located in a variable vacuum chamber 17. The constant vacuum chambers 12 and 15 communicate with each other through a pipe 7 and a channel 18, and the variable vacuum chamber 13 and 17 through a channel 20 adjustable by a screw 19.

 Through the pipe 8, the pulsator is in communication with the milk collector 4, and a vacuum wire 5 is connected to the pipe 7. Through the hole 21 with the valve 16 open, the camera 17 is connected to the atmosphere, through the hole 22 it periodically communicates with the camera 15. Through the milking machine 23, the milk pipe 3 is connected to the collector pipe 2. Its second end is connected to the milk collector 4.

 The device operates as follows.

 Before the installation is turned on, all the pulsator chambers have atmospheric pressure, the membrane 14 is horizontal, the valve 15 is open, the piston 9 under the action of the spring 10 occupies the upper position, providing communication between the nozzles 7 and 8.

 After turning on the installation, the pressure in the chambers 12 and 15 decreases sharply and the piston 9, overcoming the resistance of the spring 10, lowers, separating the pipe 7 and 8.

 At the same time, when the pressure in the chamber 15 decreases and its previous value in the chamber 13 is maintained, the membrane 14 rises, and the valve 16 closes the hole 21 and opens the hole 22. This provides a quick decrease in pressure in the chamber 17 and gradual, given the adjustable cross section of the channel 20 in the chamber 13.

 When a vacuum occurs in the chamber 13 under the action of the spring 10, the piston 9 rises, providing a message between the nozzles 7 and 8. Through the nozzle 8 and the milk collector 4, the vacuum is transferred to the milk duct 3, and the milking machine 23 to the collector pipe 2, ensuring the suction of the washing liquid from the bathtub into milk line, milk collector and flushing of the indicated elements of the milking unit.

 At the same time, by equalizing the pressure in the chambers 13 and 15, the membrane lowers, and the valve 16 opens the hole 21 and closes 22. Through the hole 2, atmospheric air fills the chamber 17, then gradually enters the chamber 13 through the channel 20. In this case, conditions are created for repeating the cycle.

 Periodic communication and uncoupling by the piston 9 of the nozzles 7 and 8 creates the conditions for periodic suction of the washing liquid from the bath and ensures the pulsating nature of its movement along the milk-conducting tracts of the milking unit. In this case, the pulsating vacuum in the system does not cause water hammer, as it can be with a sharp interruption of the fluid flow in the prototype. The pulsation frequency of the flow and the volume of fluid sucked in 1 cycle is regulated by the screw 19 of the pulsator.
