(54) GRANULATOR

I

BACKGROUND OF THE INVENTION The invention relates to technical means for the production of granulated feeds in animal husbandry.

Granulators are known, the pressing unit of which is an annular matrix with rollers 1.

Their disadvantage is the low efficiency of granule production and low productivity.

Also known granule torus-briquetti. Machine, including a flat matrix with through channels and tapered rollers 2.

A disadvantage of the known device is low productivity when granulating lightweight materials, such as dry stalk feed, since the rollers can capture a thin layer of compressible feed.

The purpose of the invention is to increase the productivity of the granulator.

The goal is achieved by the fact that the granulator is equipped with a scraper, which is located above the matrix, and a mechanism for ejecting the granules, made in the form of particles, each of which has a brush with a spring and is installed in the pressing channel of the matrix, and a horizontal cylinder, located under the matrix and interacting with by means of rods, with the cylinder being placed between the point of contact of the roller with the die and the scraper.

5In addition, the granulator is equipped with a knife,

which is installed above the matrix between the place of its contact with the roller and the cylinder. Such a design provides for the capture and pressing of a thick layer of feed in one revolution of the die.

O In FIG. 1 schematically shows the proposed granulator, side view; in fig. 2 the same, top view; in fig. 3 shows a diagram of the pressing channel.

The granulator includes a frame 1 on which a flat matrix 2 is hinged.

15 with pressing channels in which the parts of the granule ejection mechanism are located: pistons 3 and rods 4. A taper roller 6 is in contact with the die above the die on the crankshaft 5.

20 The angle between the axes of the die and the roller, as well as between the planes of their rotation, is smaller than the angle of internal friction of the compression material. The matrix is driven into rotation by means of a drive mounted on the frame, including an electric motor 7, a gearbox 8, a mechanism 9 for adjusting the gap between the matrix and the roller and the pressure roller 10. In the space between the matrix and the roller there is a feed funnel 11 and a distributor 12. A matrix 13 is placed above the matrix a receiver 14 scraps and a discharge scraper 15 with a receiver 16 finished pellets. Below the die are the details of the ejection mechanism of the granules in the form of a horizontal cylinder 17 and shield 18, which interact with the rod 4, the cylinder 17 being located between the point of contact of the matrix with the roller and the scraper, and the knife between this place and the cylinder. The porsches 3 can be sub-springs with respect to the matrix 2 by means of, for example, springs 19.

Works granulator as follows.

The matrix 2 rotates from the actuator 7-8 and due to friction forces the roller 6 entrains in rotational motion. The material to be pressed enters the granulator through the feed hopper 11, the distributor 12 is distributed along the width of the pressing part of the matrix, captured by the rotating rollers and the matrix and as a result during rotation, the distance between the die and the rollers is compressed and pressed into the die channels. Full pressing occurs at the points of its own gap between the rollers and the iodine roller with a roller 10. This gap is regulated by the mechanism 9 press the roller. Springs 19 serve to increase the uniformity of pressing of granules in ycjiOBHHx, when different amounts of material can get into different channels. They provide compression of the material with different channels filled. After the material is compressed during further rotation of the matrix, the upper parts of the granules protruding above the matrix plane are cut off by the knife 13 and dropped into the trimmer receiver 14, from where they are fed for re-granulation, and the granules are pushed out of the channels with plasma 3, the rods of which hit the cylinder 17 and raise the pistons

flush with the top plane of the matrix. In the process of further rotation of the die, the pistons are maintained in a raised position by the flap 18 until the discharge scraper 15 drops the pellets into

the receiver 16. After the collapse of the rods from the string 18, the pistons are lowered into the channels and

REPEATED.

The proposed design of the granulator makes it possible to increase the productivity and reduce the energy intensity of the process of pressing the feed.
