SU369870A1 - ADAPTATION TO LIQUID VACUUMABLE - Google Patents

Description

one

The invention relates to the field of agricultural engineering.

Adaptations to liquid evacuated containers are known to prevent liquid and foam from entering the device that creates a vacuum in them.

However, these devices do not effectively separate the foam from the evacuated air, which leads to the ingress of foam into the device that creates a vacuum in them, corrosion of the devices, reduction of their service life, as well as incomplete filling of the tank.

In the proposed device, in contrast to the known, the container is provided with a chamber recessed therein with an outlet branch pipe and a foam reflex shield placed therein, communicating with the reservoir through an additional pipeline, the bottom of the chamber serves as a float cover.

The drawing shows the described device, side view.

It consists of a pipe /, exhaust air, with a safety valve 2, a chamber 3 with a float cover 4 and foam deflector shield 5, an additional pipe 6 with a safety valve 7 and an emphasis 8 of the float cover.

A device that creates a vacuum (not shown in the drawing), such as a pump, is connected to the tank to fill it with liquid. Air from the tank is discharged.

on the pipe. Under the action of the vacuum, the liquid fills the container. Before the liquid reaches the float cover 4, air is vented through chamber 3 and the additional pipe 6. When closing

With the float cover fluid, air is vented only through an additional pipeline. Formed foam with air through an additional pipeline enters the chamber 3, where the foam

is separated from the air due to a sharp change in its direction (upward movement) and contact with the walls of the chamber. The settling of the foam in the chamber contributes to blowing its incoming air. Through the hole

foam shield and safety valve air enters the discharge pipe / and the pump without foam. The filling of the container is terminated as a result of the action of the F-1 valve on the safety valve 2, which ensures that the container is completely filled.

When emptying the float tank

 lowered all the way to 8 and out of the chamber

resulting fluid and foam entering there.

Claims (2)

1. Adaptation to liquid evacuated containers to prevent foam from entering the device that creates a vacuum in them, including a safety valve installed on the air outlet pipe, characterized in that, in order to more effectively separate the foam from the evacuated air, the tank is equipped with it has a chamber with an outlet branch pipe and a foam deflector shield placed in it, which communicates with the container through an additional pipeline, with the bottom of the chamber serving as a floating cover. 2. The device according to claim 1, characterized in that the additional pipeline is equipped with a safety valve.
