Description

Disk dspergators relate to devices for the finest grinding of materials, obtaining various suspensions and emulsions and other similar operations.

The working part of a conventional disk (; a new disnerger consists of two flat disks (rotor and stator), on the surface of which concentric protrusions are arranged, solid or cut by radial channels.

The discs are mounted with a small gap relative to each other; skipping the coarse mixture through this gap {5dedet to grinding, abrasion and mixing of the material. In order to increase the efficiency of the cutting action of the protrusions of the rotor and the stator, it is proposed to perform the angles of inclination of these protrusions in opposite directions, then when the rotor rotates, the edges of the protrusions will perform a cutting action like scissors. FIG. Figure 1 shows a cross-section of the working discs, moreover, a refers to the protrusions of the stator, and b-the rotor.

In addition, in order to improve the intake of the mixture into the central part of the gap, it is proposed to supply the discs with not one but several wide inlet sections

shown in FIG. 2). At the same time, the exit portions (and radial channels) deepen as they approach; center, which promotes the advancement of the material to the central part of the disks.

Shown in FIG. The 3 section of the disk represents a co6oii combined version of the dispersant, in which the protrusions of the disk are of the usual triangular type, but the entrance sections of the radial channels are made with a non-gradual recess as they approach the central part of the disk.

Claims (3)

1. Disk disperser, rotor i; the stator of which have working surfaces made in the form of concentric depressions and 5 protrusions intersected by radial curvilinear channels, which is distinguished by the fact that. In order to improve disnergy 1, the working surfaces of the rotor and stator have projections made at an angle to the main plane of the discs, with the inclination of the protrusions of the rotor and the protrusions of the stator opposite, and the shape of the cross-section looks like fig. one. 2. A disperser according to claim 1 with several input sections on the top of the disks according to FIG. 2 3. Dispersant according to claims 1 and 2 (or of the already known type with triangular MP protrusions) with radial channels made inclined to the main plane of the disks, respectively, FIG. 3 FIG. 2
