Description

one

The invention relates to the industry of building materials, namely, devices for the preparation of gypsum mixtures.

Closest to the present invention is a continuous mixer for preparing gypsum mixes, comprising a cylindrical body with loading and unloading nozzles, in which a drive hollow shaft with a distribution plate is located, the end part of which is perforated and has fingers fixed to the hollow shaft on it. one.

A disadvantage of the known stirrer is the low quality of the mixture due to the uneven distribution of ashes.

The purpose of the invention is to improve the quality of the mixture by ensuring uniform distribution of the foam.

This goal is achieved by the fact that the continuous mixer for the preparation of gypsum mixes, comprising a cylindrical body with loading and unloading nozzles, in which a drive hollow shaft with a distribution plate is located, the end part of which is perforated and has radial brackets fixed to it

with parallel fingers to the hollow shaft, made with radial ribs on the inner surface of the camera in communication with the hollow shaft and located g on the end of the perforated shaft between the distribution plate and the brackets with the fingers, the latter are hollow and connected to the camera through channels made in the brackets.

FIG. 1 shows the proposed mixer, cut; in fig. 2 - section A-A of FIG. one.

The continuous mixer for the preparation of gypsum mixes contains a cylindrical body 1 with loading 2 and discharge 3 nozzles in which a drive hollow shaft 4 with a distributor plate 5 is located. The end part 6 of the shaft 4 is perforated and fixed to the radial arms 7 parallel to the hollow shaft 4 fingers 8.

The hanger is made with a radial ribs 9 having a chamber 10 on the inside surface, communicating with a hollow shaft 4 and located on the end perforated shaft part between the distributor plate 5 and the brackets 7 with fingers 8, which have channels 11 and are connected to the camera by means of 7 channels 12.

The shaft 4 is driven by the drive 13.

The mixer works as follows

The drive 13 is driven into rotation by the hollow shaft 4 with the distributor plate 5 and the brackets 1. Gypsum is fed to the loading nozzle 2, and water with the foaming agent flows through the hollow shaft 4 into the chamber 10 at the same time. With intensive mixing of water with a foaming agent in the chamber 10, foam is formed, which through the perforations of part 6 and simultaneously through channels 11 and 12 due to excessive fluid pressure inside the cavity of the shaft 4 and chamber 10 and the action of centrifugal forces that occur during rotation of the shaft housing 1 is evenly distributed in the gypsum mass. The finished gypsum mixture is continuously removed through the discharge nozzle 3.

The proposed mixer can significantly improve the quality of the mixture due to uniform distribution of the foam.
