The invention relates to devices for the simultaneous preparation of gypsum mixtures with different densities.

The purpose of the invention is the expansion of technological capabilities by simultaneously preparing mixtures of different densities.

The drawing shows a schematic of a mixer.

The mixer includes a housing divided by a horizontal diaphragm) with a hole 2, into the upper and lower chambers 3 and 4 with water supply lines 5 and foaming liquid 6 o. The upper chamber 3 has loading and unloading devices 7 and 8, and the lower chamber 4 - unloading device 9. In the case there is a hollow shaft 10c with a distribution plate 11, the end part I of which is perforated and has a partition 12 at the level of the diaphragm, and on the outer surface of the shaft 10 are fixed radial arms 13c with fingers 14 "

The mixer works as follows.

The mixture of gypsum into the carrier with aggregate and additives is introduced through the loading device 7 onto the distribution plate 11 and is evenly dispersed throughout the volume of the upper chamber 3. Water is simultaneously fed through the conduit 5 through the perforations of the drive hollow shaft 10. Under the action of the radial arms 13 with the fingers 14, the components are mixed and part of the mixture obtained through the discharging device 8 enters the post formation of the products, and the other part — che

Cutting the opening 2 in the diaphragm I is directed to the lower chamber 4, where a foaming fluid is simultaneously supplied from the pipeline 6 through the perforation of the hollow shaft 10. Under the intense effect of the radial arms f3 with the fingers 14, foaming liquid is produced with simultaneous mixing and penetration of the gypsum concrete mixes. The prepared mesh or porous mixture is also fed to the post forming for the preparation of building products with different density in thickness.

Claims (1)

Invention Formula A mixer comprising a cylindrical body with a diaphragm with an opening dividing it into the upper and lower chambers, the bottom, loading and unloading devices, water supply pipelines and foaming liquid located in the body and having fingers perforated hollow shaft with a partition inside it, characterized by that, in order to expand technological capabilities by simultaneously preparing a mixture of different density, it is equipped with an additional discharge device located on the diaphragm The partition is located in the shaft at the level of the diaphragm, the diameter of the upper chamber 1.4-1.6 times the diameter of the lower chamber, while the axes of the loading device and the holes in the diaphragm are located on one side of the shaft, and the axes of the unloading devices are on the housing wall on the same side of the shaft
