Description

The invention relates to the field of accounting, primary processing and storage of milk at livestock farms and milk collection points and can be used in agriculture in systems of accounting, transportation and storage of milk and other liquid products, including when dispensed to consumers at farmer dairy plants and farms processing milk.

Known milk meters for milk pipelines of livestock farms, see, for example, a group milk counter, and.with. USSR No. 351507, comprising a housing with a prefabricated chamber, a float, dosing and counting devices, an electric drive. The disadvantage of this device is poor washability, requiring manual disassembly, design complexity, high material consumption, high capital and operating costs.

Of the known devices for metering milk in the milk pipelines of livestock farms, the closest in technical essence to the proposed device is an electromagnetic meter - a flow meter used to record milk in milk pipelines (see, for example, Kremlevsky PP Flowmeters and counters of the amount of substances. Publishing House Polytechnic, St. Petersburg, 2004, p.302 ... 336), consisting of a receiving pipe, a flow transducer with a pipe made of non-magnetic material connected to the milk collector of the milking unit, a magnet with poles , Electrodes arranged perpendicular to the motion of milk, as well as a computing device.

The disadvantage of this device is its limited use on farms due to the need to equip them with large tanks when working in milk pipelines with random modes of milk intake, including in vacuum milk pipelines, where the milk follows in the form of a milk-air mixture and the guaranteed filling of the cross section of the flow converter pipe is not ensured, without which the normal operation of the device is impossible.

The objective of the invention is to reduce capital and operating costs, ensuring that random milk flows are accounted for, including in vacuum milk pipelines and guaranteed filling with milk of the entire cross section of the flow converter pipe.

As a result of the use of the proposed invention, capital and operating costs are reduced, and random milk flows are recorded, including in vacuum milk pipelines and guaranteed milk filling of the entire cross section of the flow converter pipe.

The above technical result is achieved by the fact that in the proposed device for metering milk in milk pipelines of livestock farms containing a receiving pipe, a flow transducer with a pipe of non-magnetic material connected to a vacuum milk collector of the milking unit, an electromagnet with poles, electrodes mounted perpendicular to the movement of the milk flow, and also a computing device, between the receiving nozzle and the flow transducer a flow transducer is installed, consisting of a receiving ka ery, the upper part of which is connected by a vacuum pipe to the evacuated milk collector of the milking unit, and a float valve is installed in the lower part of the receiving chamber, blocking the inlet of the pipe of the flow transducer mounted on the outer surface of the bottom of the receiving chamber, and the pipe of the flow transducer is connected by a bend made with a vacuum nozzle at the upper edge of the flow transducer and further with a vacuum milk collector, milking vacuum and milk pumps oh installation.

To simplify the design, increase reliability and ensure self-alignment of the float valve float, it is made spherical, and the bottom of the receiving chamber is conical, and in the lower part of the conical bottom there is an inlet of the flow converter pipe blocked by the float valve.

The invention is illustrated in figures 1 and 2. Figure 1 shows a General diagram of a device for metering milk in milk pipelines of livestock farms, figure 2 shows a section aa of the proposed device.

A device for accounting milk in the milk pipelines of livestock farms contains a receiving pipe 1, a flow transducer 2 with a pipe 3 made of non-magnetic material connected to a vacuum collector 4 of the milking unit, an electromagnet with poles 5, electrodes 6 mounted perpendicular to the movement of the milk flow, computing device 7, and between the inlet pipe 1 and the flow transducer 2 is installed a flow transducer 8, consisting of a receiving chamber 9, the upper part of which is connected by a vacuum pipe 10 with a vacuum a milk collector 4 of the milking unit, and a float valve 11 is installed in the lower part of the receiving chamber 9, blocking the inlet of the pipe 3 of the flow transducer installed on the outside of the bottom of the receiving chamber 9, the pipe 3 of which is connected by a bend 12 with a vacuum pipe 10 at the level of the upper edge of the flow transducer 2 and further with evacuated milk collector 4, vacuum and milk milk pumps of the milking unit (not shown in the diagram).

A device for accounting for milk in the milk pipelines of livestock farms works as follows.

Through the vacuum milk lines, the milk-air mixture from the milking machines from the group of cows enters the receiving pipe 1, and then into the receiving chamber 9 of the flow converter 8 and, being separated from the air, accumulates in it. The float of the float valve 11 pops up and the hole formed by the end of the pipe 3 of the flow transducer 2 opens. The air entering with the milk-air mixture is separated and follows the vacuum pipe 10 into the milk collector 4 to the vacuum pump of the milking unit (not shown in the diagram). The flow of milk, which is an electrically conductive liquid, fills the pipe 3, made of non-magnetic material, and follows between the poles 5 of the electromagnet of the flow transducer 2. As a result of the interaction of the milk flow with the magnetic field on the electrodes 6 of the flow transducer 2, a potential difference proportional to the volumetric flow of milk is formed. In the computing device 7, this signal is integrated over time and a signal is generated that is proportional to the amount of milk passed through the measuring cross section of the device. If the flow rate exceeds the feed stream and the receiving chamber 9 is empty, the float valve 11 float is lowered and closes the hole formed by the end of the pipe 3 of the flow transducer 2, and the milk flow through this pipeline stops. The count in the computing device is paused. With new arrivals of the milk-air mixture, the process repeats. If milk follows a random flow, including when it flows by gravity, the float valve 11 opens and the operation of the milk metering device resumes. This ensures the filling of the cross section of the pipe 3 of the flow Converter 2.

The implementation of the float valve 11 in the form of a spherical float, overlapping the inlet at the bottom of the conical bottom of the receiving chamber 9, ensures the effective operation of the device for metering milk in milk pipelines in a mode of variable intensity of milk flows.

Computing device 7 introduces correction factors that take into account edge effects caused by the inhomogeneity of the magnetic field generated by the poles 5 of the electromagnet; shunt action of the pipe 3; the influence of the frequency and relative duration of the pulses arriving at the computing device 7 from the electrodes 6 of the flow transducer 2. The measured volume of milk is generated by a universal pump (not shown in the diagram) from the evacuated milk collector 4 to the consumer.

For guaranteed filling of the pipe 3 of the flow transducer 2, the pipe 12 is made with a bend and connected to the vacuum pipe 10 at the level of the upper edge of the flow transducer.

The proposed device for recording milk in the milk pipelines of livestock farms can work in milk pipelines with random feed flows, including vacuum milk pipelines, where the milk is in the form of a two-phase gas-liquid mixture. The possibilities of using it on farms are expanding significantly, there is no need to use large-capacity storage tanks for milk storage and guaranteed filling of the measuring section of the converter pipe 3, which reduces capital and operating costs, maintains milk quality and reduces losses.
