(54) AUTOMATIC MIXING AND DOSING DEVICE FOR POWDERED DYES

 G.

The invention relates to mixing and dispensing devices and can be used in chemical stations of the dyeing and finishing production of light industry.

A device for obtaining dispersions or solutions from powdered materials is known, which contains a rotating device with a rotor equipped with rows of teeth and with a stator, a loading hopper and a screw 1. A device for metering powders is known. Co-shaped materials containing a relay and a feeder with two sector flaps and a ripper 2.

Closest to the proposed invention is a 5 cue automatic mixing-dosing device for powdered dyes, containing a tube with spray nozzles placed in it, a tank with a stirrer and a container with a powdered dye 3.JQ

However, such devices do not provide automatic unloading of certain doses of powder from the container and mixing it in a predetermined ratio with the liquid.

The purpose of the invention is to automate the processes of loading doses of powdered dye and mixing them with a liquid.

This is achieved by the fact that the device additionally contains an airgaslift and an air separator connected to the pipe, a tare weight sensor, an automatic scale, a pressure regulator, a pyazmozadchik, a pressure gauge, a pneumatic booster, a pneumotumbler, a shut-off pneumatic valve installed at the entrance to the pipe, while the output of the sensor is the container is connected to a three-way electric-valve, the output of which is connected through a pneumatic sensor with a manometer and a pneumotumulator, the output of the pyvmotombulator is connected via a gas pressure regulator to the gas inlet outlet and through a pneumatic valve silica gel with shut-off pneumatic valve.

The drawing is a schematic diagram of an automatic mixing and dosing device.

The device contains a pipe (mixer) 1, ergazlift 2, air separator 3, spray nozzles 4, shut-off pneumatic valve 5, pneumatic booster 6, pressure gauge 7, pressure regulator 8, pneumotumbler 9, air deflector 10, three-way electropneumatic valve 11, sensor 12

Price of packaging, automatic scales 13, tpru 14 with an irrigated dye and a tank with a mesh; 1Loy 15.

The device works in the following way. Compressed air through an open three-way electropneumatic valve 11 enters the input of the nevazozatchik 10, where the pressure gauge 7 is installed according to the pressure gauge 7, Depending on the parameters of the Pressure regulator 8, the setting of which depends on the height of the container and the specific density of the powder. The installation turns on the pneumohummer 9, through which the set pressure is supplied to the pneumatic booster 6 and further to the shut-off pneumatic valve 5, which opens and supplies liquid to the spray nozzles 4. At the same time, the set pressure goes through the pneumotumbler 9 to the pressure regulator 8, where it decreases depending on the setting, it enters the entrance of an ergazlift 2 immersed 20 in a container 14 with a powdery dye, which is mounted on an automatic scale 13. The air entering the zirgaslift 2 picks up the particles and a powdery colorant and brings them into the tube (mixer) 1, 25 where they oroshayuts spray liquid and mixing with the pulp-like mass in them settle in a tank containing a stirrer 15, wherein, stirring uniformly to, are dissolved. The air enters the atmosphere through the air separator 3. After 30 unloading of the specified powder weight, the device is turned off by a signal from the sensor 12 of the automatic balance 13, which is fed to a three-way electric pneumatic valve 11, which, when closed, stops feeding the compressed air 35 and discharges it from the system.

Using the device will allow it to be used for automatic unloading of certain

pre-) powdered criss-1: 1 with one-time mixing it with liquids, which will reduce the gland claws by unloading the powder and generally by cooking; dyes, as well as improved working conditions and safety techniques.

Formula of the Invention An automatic mixing and dispensing device for porous dyes containing a tube with spray nozzles disintegrated in it, a tank with a megnalka and a container with a powdery dye, which is similar to the fact that, in order to automate the process of unloading of the doses of powdery dye, and to make the dressing of unloading of the charge of dyeing and combining dye unloading, in order to automate the unloading process of unloading of the charge of dyeing, and to mix the unloading of unloading, in order to automate the discharge of the unloading process for the discharge of the unloading of the powder for the discharge of the discharge of the powder, and in the case of the unloading of unloading of the charge for the dye unloading, and for combining the unloading of the powder, and using the unloading process , the device additionally contains an earth screen and air separator connected to the pipe, a tare weight sensor, automatic scales, a pressure regulator, a pneumatic sensor, a pressure gauge, an amplifier, a pneumatic the motorized rotary valve, pneumatic valve installed at the inlet to the pipe, while the output of the tare weight sensor is connected to a three-way electric pneumatic valve, the output of which is connected through a pneumatic sensor with a pressure gauge and pneumotumbler; pneumatic valve.
