Description

The invention relates to the preparation and dosing of dyes and chemicals.

The aim of the invention is to grow the field of application by obtaining the possibility of simultaneous dosing, and mixing several liquids directly in the metering device itself.

The drawing shows a schematic diagram of a dose mixer, an option for three components — the main and two additional components.

The mixer dosing unit contains the main 1 and additional 2 and 3 constant level supply tanks, in which the main 4 and the additional 5 and 6 airlift siphons, the receiving-funnel 7 and the three-way valve 8 are installed. Chiki - 9 - 11 with gauges 12 - 14,. . pneumatic valves 15–17, time relay 18, pulsator 19, power amplifier 20-power, mixture composition analyzer 21 and controllers 22- 24 pressure.

Dosing mixer works as follows.

Before starting work, the setting units 9-11 adjust the pressure of the compressed air supplied to the upper airlifters of the airlifting siphons, thereby adjusting their performance and the composition of the resulting mixture. The time relay 1 is turned on, the output signal t of which closes the three-way valve 8, switching the message through it from the funnel / atmosphere to connecting it to the pneumatic outlet 15. In addition, the same signal turns on the impulser 19 which gives a short-term signal to start the Airlifto Siphon 4, coming in its nozzle through the power amplifier 20, and also closes the normally open valves 15-17, sealing the upper bends of the airfoil to improve the conditions for their start-up. Erliftophon 4 starts working, while in its upper part, t . in the funnel 7, a vacuum is created, due to which fluids from the supply tanks 2 and 3 through the airlifting pumps 5 and 6 into the funnel 7 are flooded. The launch field of the airlifting pumps is switched off, pneumatic valves 15 to 17 are opened, compressed air from the sensors 9-11 is opened enters the upper knee of the airlifsiphon.

During operation, the productivity of airlift siphons depends on the geometrical parameters of airlift siphons, the level of liquid in supply tanks and the pressure of compressed air supplied to the upper knees of airlift siphons, since all these parameters are constant: -1Y, then the performance of airlift siphons is constant, therefore the ratio of components The mixtures at the outlet of the airlifting system 4 are also constant.

The mixing of liquids occurs in the funnel 7 and the outer tube of the air lift 4, i.e. directly in the dispenser. After a predetermined time has elapsed, relay 18 is turned off, the three-way valve 8 is opened, together with the upper knee of the airlifting siphon 4 through the funnel 7 with the atmosphere, the vacuum in the upper knee of the siphon 4 siphon disappears, the siphon collapses, and the dosing stops.

P, and based on this principle of operation, we can construct a closed system for automatic regulation or stagnation of the composition of the mixture. The mixture coming from erlifosiphon 4 enters the analyzer 21 of the mixture composition (for example, an automatic concentrator), which, depending on the concentration of components contained in the solution, changes the setpoint by the regulator 22.23 or 24 pressure, this pressure enters the upper knees 2-4 airlifters, changing their performance to the required value.

A batcher-mixer is economical, since the start and stop of additional airlifting agents does not require additional sources of energy, but only due to the movement of the liquid, mainly erliftosiphono,
