FIELD: process engineering.

SUBSTANCE: invention relates to crushing devices and can be used in cereal-processing industry, food industry, etc._. Proposed roll crusher comprises crushing chamber accommodating crushing rolls, loading hopper, feeder communicated with crushing chamber via chute. Crusher feeder represents scraper conveyor with rubberised scrapers. Note that conveyor case incorporates two fine- and wide-meshed sieves to separate cereals to be crushed. Fractions produced in crushing come into collectors arranged on crusher and, further on, to recycling, while cleaned cereals to be crushed are fed via collector and feed hopper for crushing.

Description

The invention relates to devices for grinding material, in particular to roller machines used in grain processing, food and other industries.

Known flattening unit APF-5 (flatting unit for grain) [1], consisting of a roller mill (grain conditioner), comprising a housing in which rollers for flattening are installed rotatably, as well as a hopper with a metering mechanism, a loading scraper conveyor, a screw feeder, unloading scraper conveyor mounted on a frame with a movement mechanism.

The disadvantage of the conditioning unit is that the grain material fed to the roller mill using a scraper conveyor using a screw feeder is not cleaned of impurities contained in it, which reduces the quality of the produced animal feed - rolled grain.

It is closest in technical and technological essence to the proposed invention and therefore it is taken as a prototype roll conditioner for grain [2], containing a loading hopper, a chamber inside which are mounted parallel rotating rollers for grinding (conditioning) of grain, loading device - feeding auger (screw conveyor ), the upper part of the body (pipe) which is made in the form of a cylindrical sieve for separation of large impurities from the grain material received for grinding, connected to the chamber for pl scheniya grain by nutrient hopper (estrus).

The disadvantages of this roller mill conditioner for grain are: unstable supply of grain to be crushed into the conditioning zone due to clogging of the holes of the cylindrical sieve of the feeding screw conveyor with grain impurities caused by the use of the screw as a cleaning and feeding mechanism, which reduces the productivity of conditioning; the design of the roller conditioner for grain does not imply the isolation and disposal of the small impurities contained in the grain material received for grinding, which leads to a decrease in the quality of the finished animal feed - rolled grain.

The objective of the invention is to develop a roller conditioner for grain, providing due to the design of the feeding device, the stability of the supply of grain to be crushed (flattening) into the conditioning zone, which will increase the throughput of the conditioner, as well as providing the separation of large and small impurities from the crushing (conditioning) ) grain material, thereby improving the quality of the resulting finished animal feed - rolled grain.

The problem is solved by means of a roller conditioner for grain, including a chamber for conditioning, inside which are mounted parallel rotating rollers for grinding (conditioning) of grain, a feed hopper, a feeding device connected to the chamber for conditioning of grain by means of a feed hopper (estrus), characterized in that the feeding device is a scraper conveyor with rubberized scrapers in the housing, in the lower wall of the housing for separation of the grain material received for grinding (conditioning) after Two sieves are carefully mounted, respectively, with small and large openings, while the fractions of small and large wastes obtained during separation are fed to the receivers installed on the conditioner and discharged through them, and the cleaned grain to be minced (rolled up) is fed to the receiver and the feed hopper flattening.

Rubberized conveyor scrapers that move the grain material received for grinding (flattening) along the bottom wall of the conveyor body and sieves for separation simultaneously clean the sieves of grain particles and impurities stuck in the holes of the sieves, which ensures the continuity of the separation and feeding of grain for flattening. Grain material transported by conveyor scrapers along the sowing sieve (sieve with small holes) is cleaned of fine impurities on it and fed to the spike sieve (sieve with large holes), where grain to be crushed (flattened) passes through the holes of this sieve and enters the nutrient conditioner hopper for subsequent grinding (conditioning), and large impurities remain on the sieve and then are removed from it by rubberized scrapers for disposal.

Therefore, the present invention — a roller mill conditioner for grain — solves the set tasks: it ensures, due to the design of the feeding device, the stability of the feed of grain to be crushed (flattening) into the conditioning zone, which leads to an increase in the capacity of the conditioner, and also provides the separation of large and small impurities, contained in the grain material received for grinding (flattening), thereby improving the quality of the finished animal feed - flattened grain.

The drawing shows a roller conditioner for grain.

Roller conditioner for grain consists of a chamber for conditioning 1, inside of which are mounted parallel rotating rollers 2 for grinding (conditioning) of grain, a feed hopper 3 with an adjustment flap 4, a feeding device, which is a scraper conveyor 5 with rubber scrapers 6 in the housing 7, connected with a chamber for crushing grain 1 by means of a feed hopper (estrus) 8, while the lower wall 9 of the conveyor body, along which the grain material received for grinding (crushing) moves, consists of three interconnected sections: an all-metal plate (section AB), a sieve with small holes (sowing sieve) (section BC) and a sieve with large holes (spike sieve) (section CD). Under the sieves BC and CD, as well as under the upper edge of the lower wall 9 of the conveyor body 7, fractions receivers 10, 11, 12 are mounted.

Roller conditioner for grain works as follows.

For example, grain material 13, which came, for example, from the field after harvesting to grinding (flattening), is loaded into the hopper 3, from where it is fed through the shutter 4 to the feeding device — the scraper conveyor 5. Then the grain material is transported by rubber scrapers 6 along the lower wall 9 of the conveyor body 7 ( section AB) and enters the sowing sieve (aircraft section). As material 13 passes through the sieve, the small impurities contained in it are sifted through the openings of this sieve, get into the receiver 10 of small waste and sent through it for disposal, and the rest of the grain material is transported by scrapers 6 to the spike sieve CD. The grain to be crushed is sifted on this sieve through its openings, enters the receiver 11 of the grain to be crushed and through it into the feed hopper 8, from where it enters the chamber 1 for grinding (crushing) with rollers 2. Large impurities remain on the sieve CD, they are moved by rubberized scrapers 6 to point D of the lower wall 9 of the conveyor body, then, under the action of gravity, they enter the receiver of large impurities 12 and are sent through it for disposal.

The invention consists in the following. The rubberized scrapers 6 of the conveyor 5 moving the grain material 13 received for grinding (flattening) along the bottom wall 9 of the conveyor body, including sieves for separation of aircraft and CD, at the same time clean the sieve data from grain particles and impurities stuck in the holes of the sieves, thereby ensuring the continuity of the process separation and, therefore, the supply of grain for grinding (flattening), which increases the throughput of the conditioner. The grain material arriving for grinding (flattening), transported via sowing and spike sieves (sections of the BC and CD of the lower wall 9 of the conveyor body), is cleaned of small and large impurities contained in it, and the cleaned impurities to be crushed get into the feed hopper of the conditioner ( to flattening) grain, when flattened which receive a high-quality ready-made feed for animals - rolled flattened grain.

Thus, the use of the proposed roller roller conditioner for grain, in comparison with the prototype, solves the tasks set for it: it ensures, due to the design of the feeding device, the stability of the feed of grain to be crushed (flattening) into the conditioning zone, which leads to an increase in throughput of the conditioner, as well as provides the separation of large and small impurities from the grain material received for grinding (flattening), thereby improving the quality of the resulting finished animal feed - flattened of grain.
