And it is related to the area of permutable bulk materials with gas and can be used for the dosed mixing and psdachi and sludge fuel into a laboratory-type combustion chamber.

The aim of the invention is to provide control of the concentration of the pneumatic mixture.

Figure 1 presents the device, General view, section; in Fig. 2, view A in Fig. 1} in Fig. 3 is a section B-B in Fig. 1, in Fig. 4 is a schematic diagram with an air supply line.

The device for dispensing contains an airtight cylindrical tank 1, in which a piston 2 is installed, receiving uniform movement from the actuator 3 with adjustable speed. In the upper part of the tank 1 there is a mixing chamber 4 and a rotor-ripper in the form of a disk 5 on the shaft 6, On the bottom The face of the disk 5 has radial grooves 7 open on the side of the piston 2, the grooves 7 communicate with an adjustable line 8 for supplying compressed air through an axial vertical channel 9 passing inside the shaft 6 of the rotor-ripper, and for the sake of The nozzles 10 connected to the channel 9, Line 8 of the compressed air supply is a section of the compressed air line 11 equipped with control valves 12 and gauges 13. The line 11 of the compressed air also leaves the mixing chamber 4 and the space under the piston of the tank 1, The last of these lines serves to equalize the pressure in the tank 1 on both sides of the piston 2 in order to avoid leaks. The grooves 7 are oblong.

channels, for example, U-shaped cross-section, located mainly along the radii of disk 5 (it is also possible to arrange them along circular arcs). The ends of the channels opposite to the nozzles 10 are located along the peripheral circumference of the disk 5 and communicate with the nozzle 14 of the outlet of the pneumatic mixture from the tank 1

through the annular space at the top of the chamber 4 mix.

To effect the rotation of the ripper disc 5, an independent drive 15 is provided in the device.

direct current, connected to the rotor shaft 6.

The device works as follows.

The piston 2 is retracted to the extreme initial position opposite to the disk 5. After dismounting the mixing chamber 4, the container 1 is filled with powder, for example, coal dust, then

using the clamp 16 and the gasket 17, the container 1 and the chamber 4 are collected and sealed. The actuator 15 rotates the rotor ripper, the air supply valves 12 are opened, pressure is equalized on the supply lines 13, then the actuator 3 moves the piston 2, the mass of the powder per unit of time is controlled by this actuator, and the valves 12 independently of the material consumption the amount of air is regulated, i.e. the percentage of powder in the air. The rotation of the disk 5 provides for the turbulization of the pneumatic mixture.

uniform mixing of air with the powder. The mixture is led out through the slots 7 and injected, for example, into the model of the combustion chamber where it is burned.
