A milk measuring device and its working method

Abstract

The invention discloses a milk liquid metering device and its working method, which comprises a mounting frame, a gas-liquid separation storage structure, an electromagnetic pneumatic control structure, a negative pressure vacuum pipeline, and the gas-liquid separation storage structure and the electromagnetic pneumatic control structure are installed in the installation Inside the rack, the gas-liquid separation storage structure is located above the electromagnetic and pneumatic control structure, and the negative pressure vacuum pipeline includes at least two lines and is respectively installed on the gas-liquid separation storage structure and the electromagnetic and pneumatic control structure. The gas-liquid separation storage structure includes an upper shell with a liquid inlet, a milk storage bin, and a lower shell with a liquid outlet from top to bottom. The electromagnetic pneumatic control structure includes a solenoid valve, a solenoid valve inner core, a solenoid valve upper cover, a solenoid valve lower cover, and a solenoid valve internal kit. The present invention adopts the method of quantitative measurement, has high measurement accuracy, ensures the stability of long-term measurement, can also judge the quality of milk, and effectively eliminates the measurement error caused by vacuum in the milk pipeline.

Description

technical field [0001] The invention relates to a metering device, in particular to a milk metering device and its working method. Background technique [0002] At present, there are many types of liquid metering equipment, such as electromagnetic flowmeters, target flowmeters, differential pressure flowmeters, positive displacement flowmeters, float flowmeters, turbine flowmeters, vortex flowmeters in fluid oscillation flowmeters, and Flowmeters, ultrasonic flowmeters, and various flowmeters have different working principles. However, in practical applications, these flowmeters require the test liquid flow to be uniform and the liquid to fill the measurement section. But in non-manually milked farms, especially in modern farms, since milking is realized under the condition of negative pressure in the pipeline, this causes a mixture of air and milk to flow in the pipeline at the same time, and will produce Lots of foam. Therefore, it is difficult for the above-mentioned fl...

Problems solved by technology

But in non-manually milked farms, especially in modern farms, since milking is realized under the condition of negative pressure in the pipeline, this causes a mixture of air and milk to flow in the pipeline at the same time, and will produce lots of foam

Therefore, it is difficult for the above-mentioned flowmeters to accurately measure the milk production of cows.

At present, there are some devices and equipment for automatically measuring milk flow, but none of them can solve the foam interference in the milk production process, resulting in inaccurate measurement, or passivation or Oxidation and other chemical reactions form an insulating layer on the electrode surface, resulting in loss of reliability and accuracy of measurement
