SU1255184A1 - Mixer for pulverulent and high-viscous liquid components of continuous action - Google Patents

Description

2. The mixer according to claim 1, of which is that the supply pipe of the powder component is equipped with a vibrating screen.

3. A mixer according to claim 1, such as the fact that the screw is hollow with a screw thread

This invention relates to the continuous mixing of components in the chemical industry: highly viscous liquids with powders.

The purpose of the invention is to improve the quality of mixing.

Figure 1 shows the mixer, a cross-section along the loading zone; figure 2 - section aa on fng. on fig.Z - section bb in figure 2.

The mixer consists of a horizontal body 1, a screw 2, a rotating roll 3, knives 4 and 5, the first of which is mounted close to the roll under the screw, and the second with an adjustable clearance t,; fixed pipe 6, mated with the pipe. 7 unloading, blades 8 with grooves 9 fixed at the end of the screw, and fingers 10 fixed to the pipe 6. Roller 3 is installed parallel to the screw under pipe G1 for feeding powdered components, which is equipped with a vibrating screen 12. Pipe 13 for supplying high-viscosity fluid is located under the roller.

1Vneck 2 is hollow with screw thread 14 inside. The pipe 6 is placed in the cavity of the screw, and its fingers iO interact with the slots of the blades 8. The screw 2 and the roller 3 have separate

inside and provided with paddles with grooves fixed on the end of the drain and a fixed pipe placed in the screw cavity and adjoined to the mixture discharge pipe, while the pipe is provided with fingers interacting with the paddle blades.

adjustable drives (not shown) and rotate one towards the other. Case 1 has a shirt 15 heating. The mixer works as follows.

The viscous liquid components are metered through the feed nozzle 13 and emerge from under the knife 5 in the form of a layer t deposited on a rotating roll with a thickness t and a width of L. Powder components are dispensed through a vibrating screen 12 and are adhered to the rotating roll with a thickness t width L. Percentage

components in the unit area of the layer corresponds to the formulation of the mixed composition. A layer of viscous liquid and powdery components applied to the roller 3 by means of a rotating roller is transported to the knife 4, which removes it and guides it to the turns of the screw 2.

Due to the fact that the productivity of the outer screw threading of the screw is greater than the inner one, a reverse axial flow of the components to be mixed is created in the outer turns of the screw, and in the section between these streams the layers shift as the mixture moves radially. The mixed components are injected into the pipeline through the discharge port 7.
