The invention relates to devices for mixing viscous liquid and powder components and can be used for chemical engineering, construction.

The purpose of the invention is to intensify the mixing process.

Figure 1 shows the mixer, a general view; figure 2 - view And figure 1.

The mixer consists of a conical body 1 with a perforated conical glass 2, in the wall of which holes are made, and from the outside there is a cavity 3 communicating through the grooves 4 with the inner surface of the body 1, the cylindrical body 5, the lips 6, on which the concentric branch pipes 7 are mounted, forming annular cavities, in which powder is fed along arrow P, and liquid — along fluid arrow and which have slits for entering components into the mixer, a rotating shaft 8, on which two blades 9 are attached, not connected to a conical spiral w and having a working surface tilt in one direction from the latter, the blade 10 having Naklo opposite to the spiral bevel 11 fixed to them, conical screw blade 12 and the cylindrical, shnekrvye blade 13, the throttle 14 reshetki-.

The mixer works as follows.

Liquid (in the direction of arrow G) and powder (in the direction of arrow P) components with continuous dispensers are fed into the cavities between the concentricly arranged pipes 7, from which the liquid components are squeezed out in the form of tubular cavities, between which powdered components

You are in an appropriate weight ratio to each other.

This method of introducing components eliminates dusting in the mixer, simplifies their further mixing and protects the shaft seal from the ingress of powdered components and its rapid wear.

The blade 9 drowns the components on the surface of the loaded mixture, which in the housing 1 circulates along the axis of the mixer, as a result of interaction with oppositely directed inclined surfaces of the conical helix 11 and the blades 10.

Further, the mass, falling into conical screw blades, is finally mixed by throttling (c. By intense shearing of layers) through the wall of cone 2 with the formation of reverse and circulating flows along the axis of the screw. Worm blades 13 through the throttle grid 14, which creates a load auger, pump the finished mass to the consumer.
