Description

one

The invention relates to a device for producing granules on any basis, for example, from viscous masses, building materials, fertilizers, etc.

A granulation device is known, consisting of a rotating vessel with molding holes through which the product to be granulated is forced through a press roll, and a separating device in the form of one or more, serving to separate the product leaving the molding holes from the outer wall of the vessel. Each pressing roller of the sled can be deflected from the bottom of the vessel and pressed against it by the action of a rotating device connected to it. The axes of the vessel and the roll intersect at any angle 1.

The disadvantage of this construction is the need for a complex swivel device, which is caused by the adhesion of the granulated material to the press roll.

The closest to the technical essence of the invention is a granulator consisting of a flat matrix and a pressing roller, inside which there is a cam with blades fixed with the possibility of their radial movement along guide grooves made in the wall of the roll 2.

The disadvantage of this design is its complexity, unreliability in operation, sticking of the material on the rolls.

The aim of the invention is to reduce sticking of the material to the rolls, increasing reliability.

This goal is achieved by the fact that each blade is made of an elastic material, attached at one end to a roll, the grooves or holes are made on the outer surface of which.

FIG. 1 shows the device in plan; FIG. 2 shows section A-A in FIG. one; in fig. 3 shows a roll with a recess; in fig. 4 shows an embodiment of a roll with holes.

The granulator includes a perforated matrix 1 mounted on a conical wheel 2 supported on a roller arm 3.

In bearings 4 a shaft 5 is installed, on which the rolls 6 with elastic blades 7 are fixed. On the outer surface of the rolls 6 there are recesses 8 (see Fig. 3) or holes 9 (see Fig. 4).

The granulator works as follows;

When the shaft 5 is rotated with the bevel gear 10 and the roller 6 with the wiping blades 7, the bevel gear 2 with the die 1 rotates.

The rotation from the engine is transmitted to the cone wheel 2, and through gears 10 to two other rolls 6.

The cleaning blade 7 captures the material being granulated, compacts it and squeezes out of the space formed by the matrix 1 and the roller 6 and the cleaning blade 7 that are in contact with it, and then the material to be granulated seizes the next cleaning blade 7 and, after contacting the matrix 1, squeezes the next batch and t dd

The number of wiping blades 7 is determined by the performance and speed of rotation of the matrix 1.

The width of the wiper blades 7 is determined constructively depending on the elastic properties of the material of the blades.

One or several rollers 6 with wiping blades 7 and a corresponding number of bunkers feeding the wiping material can be installed on the matrix 1, which will increase the productivity of the whole product.

An important advantage of the proposed granulator is the elimination of sticking of the granulated material on the drum, improving reliability and ynponi; construction of the whole structure.
