Abstract

The milk meter is most clearly described as an appliance, which measures the flow of milk in the milk pipeline of the milking unit. The appliance consists of a vertically placed container, separated by a partition into a reception camera and a measuring camera. Both cameras are connected with a borehole in the partition. In the reception camera, a float is made with a hollow stem, in which a borehole is made in the top part, while on the bottom part a sealing gland is mounted to close the borehole in the partition. When the measuring camera is filled with milk, the float lifts, and is connected with the atmosphere by the borehole in the hollow stem of the float. Simultaneously, the sealing gland closes the borehole in the partition, while the top of the float stem activates the counting mechanism for the counting of milk portions. After the suction of milk from the measuring camera, the pressure in both cameras equalizes, the float with the sealing gland descends, a new portion of milk flows into the measuring camera, and the cycle is repeated.<IMAGE>

Description

Milk counter

The invention relates to the apparatus construction industry and is intended for measuring the quantity of liquid products, in particular milk.

A device for measuring the amount of milk containing a measuring chamber and a float is known.

The known device does not provide the required measurement accuracy [ij.

The closest technical solution to the present invention is a milk meter, which consists of receiving and measuring chambers interconnected with a float and a shut-off valve mounted on a single stem.

The receiving and measuring chambers are connected to an auxiliary pipe for air overflow fsj.

The known device does not provide the required measurement accuracy15.

The object of the invention is to increase the accuracy of measurement and to simplify the construction.

This is achieved by having the shaft on which the float and the shut-off valve are hollow with an open bottom end and a hole in the top of the wall which is periodically discharged from the receiving chamber during operation.

The drawing shows the proposed device.

The milk meter consists of a receptacle I closed from above with a lid 2 having a conduit 5 for connection to the milk conduit loop 4 and a conduit 5 for connection to the conduit 6 of the milk conduit 6. At the bottom of the conduit I is a threaded conduit? · A tube 8 connected to a milk duct drain 6. The interior of the vessel I is divided by a septum 9 having a bore 10 in the receiving chamber II and the measuring chamber 12. In the receiving chamber II and the measuring chamber 12. A float 15 is arranged in the receiving chamber II. the stem 14 is connected to the shut-off valve 15, the shutter closes the bore 10 during operation, the lower end of the stem 14 is open and the upper is inserted into the bore 2 of the lid and closed from above by a lock 16 acting on the counting mechanism 17 the wall has a bore 18 located ai away from the top plane of the shut-off valve up to its seating position, with the float lowered, to the bulkhead 9. The float centering switch has a plurality of guide tabs 19 on the sides of the pivot 15.

The milk meter works as follows.

Through the milk pipe 4, the milk-air mixture enters the receiving chamber II, from which the milk flows through the bore 10 into the measuring chamber 12 and the air is drawn into the milk pipe 6. When the measuring chamber 12 is filled, the milk level continues to rise until the float 13 as the milk level rises, moving the stem 14 with the seal 15 · At the moment of approaching the seat 15, the bore 14 of the stem 14 passes through the plane 2 of the lid, resulting in atmospheric air passing through this bore and the hollow shaft into the measuring chamber 12 press the shut-off valve 15 firmly against his buttocks.

As a result of the increased pressure, the milk from the metering chamber 12 passes through the outlet conduit 7 and the conduit 8 into the discharge duct 6 of the milk duct. At the same time, the upper end of the stem 14 presses the After the milk has been withdrawn from the measuring chamber 12, the pressure in both chambers is equalized, the float sealed in the milk weight receiving chamber, which acts on the seal 15, lowers, the bore IS exits the atmosphere and the cycle is repeated. When connecting the shaft to the pneumatic actuator, the last one, when the pressure increases, acts on the counting mechanism by counting portions.
