SU125733A1 - Automatic device for overflowing excess liquid from vacuum cartridges of draft machines - Google Patents

Description

Devices are known for overflowing excess liquid from vacuum filling machines of filling machines, made in the form of a vertical tank connected in the upper part of the pipe-lines with a vacuum pump and vacuum cartridges. The described device in comparison with the known ones provides higher performance. This is achieved by the fact that the horizontal partition of the tank is divided into two chambers, upper and lower, communicating with each other with the help of a lever valve, Evaimoeduyushuyush, with a float installed in the lower chamber.

A drain valve is located at the bottom of the lower chamber, and in the upper chamber there is an air pipe with a ball valve.

The device (see drawing) contains a vertical tank /, in the upper part of which there is a pipeline 2 for connecting with a vacuum pump (not shown) and a pipeline 3 for connecting with vacuum cartridges (not shown).

The tank / is divided inside by a horizontal partition 4 into two chambers 5 and b. The upper chamber 5 is equipped with an air tube 7 with a ball valve 8, and the lower chamber 6 has a float 9. The float 9 communicates with the ball valve 8 through the pusher 10 and through the lever // with the valve 12, which closes the opening 13 in the horizontal partition 4.. At the bottom of the lower chamber is a non-return valve 14.

Leaving the vacuum cartridges E left from the spill, with the help of the vacuum pump created by the vacuum pump through the pipeline 3, it is poured into the tank 1: first into the upper chamber 5, then further through the open hole 13 into the lower chamber 6. At the same time the float 9 and valve 12 are in the initial lower position; air tube 7 is blocked by a ball valve 8; the drain valve 14 is also closed and is held with a vacuum suction.

№ 125733

The fluid flowing through the pipeline 3 into the lower chamber 6 tends to lift the float 9, but the latter is held up by the pusher 10, resting abutment. With its upper end into the ball valve 8.

As soon as the float 9 turns out to be a submerged EI liquid at% of its volume, it acquires a lifting force and releases the ball valve from its socket with the help of a pusher, due to which atmospheric air and air through the air tube 7 gains access to the tank 1.

Lift up, the float acts on the lever valve / 2, which closes the opening 13, which informs the upper and lower chambers of the tank 1.

The atmospheric air entering the reservoir 1 through the air tube 7 presses on the fluid accumulated in the lower chamber 6 and displaces it through the drain valve 14 into the tank to return excess liquid (not shown).

As soon as the bottom is released from the liquid, the float in it under the action of its weight drops down, the lever valve 12 is not behind it, and the hole 13 in the horizontal partition 4 opens. Together with the float 9, the pusher 10 is lowered down and the ball valve closes the air tube, blocking the access of atmospheric air to the reservoir 1.

Subject invention

Automatic overflow device; liquids from vacuum cartridges of filling machines, made in the form of a vertical tank, connected in the upper part of the pipeline with a vacuum pump and rakoum-cartridges, characterized in that, in order to increase productivity, the tank is divided by a horizontal partition into two chambers, an upper and a lower one, communicating with each other by means of a lever valve that interacts with a float installed in the lower chamber, at the bottom of which the drain valve is located, and in the upper chamber there is an air pipe with a ball valve.
