Description

[0001] The proposed invention relates to the field of agriculture, to devices for washing milking systems, using the application of localized cleaning methods of an individual nature for each milking cup, or the milking machine as a whole.

[0002] Milk characteristics are determined by the sanitary and hygienic equipment used for milking and primary processing. Cleaning and disinfecting milking equipment is a key factor in obtaining a high-quality product. Milking machines are the most challenging component when cleaning milking equipment due to the presence of polymeric materials (teat liners, milk hoses), which are difficult to disinfect.

[0003] On the other hand, used cleaning solution is discharged into the sewer system without any treatment. Agricultural and industrial enterprises often discharge this wastewater, which contains chemical and biological impurities exceeding maximum permissible levels, into the environment, thereby causing significant harm to the environment. Therefore, the implementation of modern wastewater treatment methods will reduce the anthropogenic impact on the environment.

[0004] A known method for cleaning milking machines, minimizing the costs of performing the technological process [a.s. SU No. 1586632], reducing resource-saving costs, in which a device for cleaning the teat tubes of the subcups, comprising a base with a clamp and a recess for the teat tubes, inside which guides are installed for supplying cleaning liquid to their inner walls, made with radial protrusions on the outer surface, characterized in that, in order to improve the quality of cleaning by increasing the intensity of the mechanical action on the inner walls of the teat tubes, the guides are installed eccentrically relative to the longitudinal axes of the recesses and the teat tubes placed therein. The disadvantages of this cleaning method are high energy costs, the duration of the technological process of circulation cleaning, significant costs for cleaning concentrates, and, as a result, an increased environmental load.

[0005] A device is known for washing milking machines with activation of washing heads using collector nozzles [utility model, patent RU No. 180325], which requires stable costs for maintaining a vacuum mode, consisting of activated collector nozzles with the ability to regulate the pulsation frequency by means of a membrane pneumatic pulsator.

[0006] The closest technical solution to the proposed invention is a device for disinfecting milking machines [RU Patent No. 2786161, used as a prototype]. The device comprises a platform with an internal cavity for supplying cleaning fluid, with eccentrically mounted, rotatable collector nozzles in the form of cones with a mechanically active surface. Jet sprayers for supplying cleaning fluid and a drive mechanism for the collector nozzles are mounted on the platform. The device is additionally equipped with a centrifugal pump, ensuring bidirectional distribution of the cleaning fluid flow, and a single-acting valve mechanism, located on the inlet pipe of the milking machine collector, with an electronic pulsator, determining the pulsating supply of cleaning fluid to the teat cups.

[0007] The disadvantage of this device, which determines the technical change in the washing scheme, is the duration of washing in the entire milking system, without taking into account the washing of individual milking units and cups.

[0008] Analysis of known similar solutions showed that an important technological problem in this process is the need to reduce time by means of accelerated, high-quality cleaning of milking machines and reducing the significant environmental impact of wastewater discharge.

[0009] The technical result of the invention is a reduction in the time and cost of cleaning the milking unit due to an accelerated and localized option for individual cleaning of milking machines, as well as a reduction in the environmental impact.

[0010] The proposed hydrodynamic device for washing milking cups allows solving the stated problem, including a platform with an internal cavity for feeding a washing liquid with collector nozzles in the form of cones with a mechanically active bristled surface, eccentrically mounted on it with the possibility of rotation, on which jet sprayers for feeding the washing liquid and a mechanism for driving the collector nozzles are mounted, while the device is equipped with a centrifugal pump, providing a bidirectional distribution of the flow of washing liquid, and a valve mechanism on the supply pipe of the milking machine collector with an electronic pulsator, determining the pulsating supply of washing liquid into the milking cups, in which each milking cup is equipped with an individual modular cartridge of osmotic action.

[0011] The invention is explained by a drawing (Fig. 1), which shows a generalized diagram of the device.

[0012] The hydrodynamic device for cleaning milking cups includes a collector platform 1 with an internal cavity 2 for draining cleaning liquid, connected by a pipe 3 to the cleaning solution circulation system. On the surface of the platform 1 there are four conical attachments 4 for connecting milking cups 15 with a fixing device 5 (clamps) for their hermetically sealed fastening, having a mechanically active surface 6 (bristled surface) and jet flow distributors 7. The conical attachments are located eccentrically relative to the base of the milking cups of the milking machine placed for cleaning.

[0013] The collector platform 1 with attachments 4 is positioned similarly to the teats on an animal's udder. The milking cups 15, connected without disassembling the milking machine, and the collector 8 are simultaneously washed in a pulsating mode controlled by the frequency electronic pulsator 12 and the valve mechanism 10.

[0014] Distribution of washing liquid flows to four washing heads (four milking cups) occurs through tee 9 and manifold-distributor 16. The supply of washing solution is carried out by centrifugal pump 11. Each milking cup 15 is equipped with an individual modular cartridge of osmotic action 13 with a filter element with a semi-permeable membrane 14.

[0015] The milking cups 15, located on the washing attachments 4, are subjected to the hydromechanical action of the eccentric rotation of the washing heads. The osmotic cleaning system is provided by individual modular cartridges 13 for each cup 15.

[0016] The hydromechanical device for washing milking cups works as follows.

[0017] When washing a portable or stationary milking machine, including one that is part of robotic equipment (a milking robot), the milking actuator - the teat cups - are secured on platform 1 and connected to conical attachments 4 with fixation by clamps 5. The washing liquid is supplied under excess pressure using a centrifugal hydraulic pump 11, the flow distribution is ensured by a tee 9 and a manifold-distributor 16.

[0018] The cleaning process continues until the osmotic and hydrostatic pressures in the modular cartridge are balanced. The cleaning time of the milking units is determined by changes in system pressure; the equilibrium pressure determines the need to replace cleaning cartridges 13. Replacing a clogged cartridge involves blocking the connection system for that cartridge without disconnecting the excess pressure supply system or the cleaning fluid supply to other cartridges.

[0019] The modular cartridge system of osmotic action allows to speed up and simplify the flushing process, as well as reduce the environmental impact of wastewater discharge.

[0020] Thus, the proposed technical solution with localized cleaning of milking units (milking unit cups) using a pulsating mode of action ensures an accelerated process due to the presence of an individual modular cartridge of osmotic action for each cup and improves the quality of cleaning, reducing the cost of cleaning solution consumption and the environmental impact.
