Description

The utility model relates to devices for preparing highly dispersed and homogeneous suspensions that can be used in construction, oil production, food, chemical and other industries.

A turbo-reflector mill is known, containing a loading pipe, a housing, disk-shaped working bodies installed in it, having impact elements (author's certificate No. 351580 SU Turbo-reflector mill). The disadvantage of such a device is significant wear of the impact elements and low efficiency during fine grinding.

The prototype of the claimed utility model is a grinding device containing a loading pipe, a housing, two disk-shaped working bodies installed in it, one of which is rotatable, having rectangular impact elements on surfaces facing each other, and an outlet pipe located below ( RF patent for invention No. 2169617). The disadvantage of such a device is its low efficiency during fine grinding; it does not allow obtaining suspensions of high dispersity and homogeneity.

The purpose of the utility model is to increase the efficiency of mixing crushed solid material with liquid, obtaining a highly dispersed and homogeneous suspension.

The technical result is achieved by the fact that in a device for preparing a suspension containing a loading pipe, a housing, two disk-shaped working bodies installed in it, one of which is rotatable, having rectangular impact elements on surfaces facing each other, located at the bottom outlet pipe, the housing is connected by an outlet pipe to a chamber on the inner surface of which fender bars are fixedly fixed, and in the chamber a rotor with fender bars is mounted horizontally on a vertical shaft, and the chamber is equipped with a pipe for supplying liquid to the center of the rotor and a discharge hole for removing the finished suspension.

The utility model is illustrated by drawings, where in Fig. 1 shows a general view of the device for preparing the suspension; in fig. 2 - view of the body according to A-A.

The device for preparing the suspension contains a loading pipe 1, a housing 2 with an outlet pipe 3 located below. The housing is connected by a cylindrical outlet pipe with a flared end to a chamber 4. Baffle strips 5 are fixedly fixed on the inner surface of the chamber. In the chamber, a rotor is mounted horizontally on a vertical shaft 6 7 with bumper bars 8. The chamber is equipped with a pipe 9 for supplying liquid to the center of the rotor and a discharge hole 10 for removing the finished suspension (Fig. 1).

Two disk-shaped working bodies 11 and 12 are installed vertically in the housing, one of which is rotatable on a shaft 13. The working bodies have rectangular-shaped impact elements 14 on their surfaces facing each other (Fig. 2).

All parts of the device are made of wear-resistant and corrosion-resistant material (for example, steel).

The device for preparing the suspension operates as follows.

Through the loading pipe 1, solid material is supplied to the housing 2. The material falls between two disk-shaped working bodies 11 and 12, one of which rotates on the shaft 13. In this case, the material is subjected to mechanical action of rectangular impact elements 14, mounted on the surfaces of the working bodies facing each other (Fig. 2). The crushed material from the housing is directed through the outlet pipe 3 into the chamber 4, on the inner surface of which the fender bars 5 are fixedly fixed. When the rotor 7 with the fender bars 8, installed horizontally in the chamber on the vertical shaft 6, rotates, additional grinding of the solid material occurs, which is mixed with liquid supplied through pipe 9 to the center of the rotor. In this case, a suspension of high dispersion and homogeneity is obtained, which is removed from the chamber through the discharge opening 10 (Fig. 1).

Such a device is not difficult to manufacture and operate and provides a highly dispersed and homogeneous suspension.
