SU97201A1 - Device for automatic control of the ratio of two mixable liquids - Google Patents

Description

The known devices for automatic control of the ratio of two mixable liquids, for example, molasses and water, using a float suspended from the balance beam as a sensor, do not provide accurate dispersing of liquids.

In the proposed device, this disadvantage is eliminated due to the suspension of a hollow cylinder in the second arm of the balance arm that changes the balance when the balance arm rotates, for one of the fluids, and for better mixing with the second fluid The latter is designed as an annular injection device surrounding the central inlet of the first liquid.

The drawing shows schematically the described device.

The mixing chamber of the device is made in the form of a vessel (cylindrical), closed with a glass bell 2. The liquids to be mixed are fed to the upper part.

The inlet for one of the liquids (for example, molasses) is made in the form of a glass 3 with openings 4.

This fluid through pipes 5 enters the cup 3 and is poured through the holes 4 towards the second fluid (for example, water), which is supplied by an annular spray device 6 surrounding the central inlet of the first fluid.

The resulting mixture of liquids flows into the lower part of the device, where it is stirred by the stirrer 7, flows down the plates 5 with the caps 9 and enters the tank 10, from which it flows through the overflow holes 11 to the outlet part 12 of the tank 10 and goes to the production pipe 13. At the same time, a part of the scatter entering the tank 10 is retracted into the device (branch) 14 for checking the density with the help of a hydrometer 15.

In the tank 10, the float 16 is immersed, 18 weights suspended from the beam are immersed on the rod 17.

A gate in the form of a hollow cylinder 19 is suspended to the second shoulder of the balance arm 18, which changes when the balance arm swings, caused by a change in the backing density, the area of the openings 4 of the cup 3 and thereby reducing or increasing the amount of the first liquid supplied to the backing pad (for example, molasses). Consequently, the first liquid (e.g., molasses) and the second liquid (e.g. water) are continuously supplied to the mixing chamber and continuously supplied with an adjustable flow rate.

Subject and d on and e and

Prib (-p for automatic control of the ratio of two mixable liquids (for example, molasses and water) using a float suspended from the balance arm as a sensor, characterized in that, in order to more accurately scatter fluids, the gate in the second balance arm arm is suspended in the form of a hollow cylinder that changes when the balance arm rocker swings, the area of the inlet openings, for one of the fluids, is applied, and for better displacement with the second fluid, the latter is supplied as an annular injection a nodding device surrounding the central inlet of the first fluid.
