Description

The invention relates to feeders for providing an even supply of raw bulk materials from bunkers and can be used in boiler installations for the supply of high-moisture coal, lignite and milled peat.

There are known feeders for feeding raw bulk materials, for example, high-moisture coal with clay inclusions, containing a receiving pipe of a rectangular cross-section and a scraper feeder with a web mounted under it, having two working branches (lower and upper), tensioned by means of drive sprockets and tension commercials.

In these feeders, it is not possible to adjust the angle of inclination of the working branch depending on the angle of the natural slope of the feed material, which makes it difficult to obtain a uniform feed of the material when its properties change.

To adjust the iodo angle of the lower working branch depending on the properties (angle of repose) of the supplied material, the tension rollers are made interchangeable with the possibility of movement in a vertical plane.

By using replaceable rollers of different diameters and moving them in a vertical plane, you can change the angle of elevation of the lower working branch.

The feeder includes a housing 1 with a receiving wire 2 with rectangular section and output 3. The housing is equipped with a scraper dispenser with canvas 4, tables 5 and 6, corresponding to the upper and lower ones, ppNBO .iHbiMii with asterisks 7 and tensioned rollers 8. Under terminal 3 is installed a conveyor (not shown in the drawing) for the shifted material to the place of punching. The scraper dispenser blade has two working branches, the upper one with a table 5 inclined in the direction of movement of materials, and the lower one completed with a rise in the direction of movement of material. In 1, above the upper working branch of the blade 4, a regulator of 9 layers is installed at the pipe 2.

The feeder works as follows.

The raw fuel comes from the bunker through the nozzles 2 onto the inclined BepxHnii table 5. Next, the fuel is moved by scrapers of the upper working branch but from goal 5 and transferred to the lower CTOJ 6 of the dispenser, then the lower worker; One branch pops up on the table and is dumped through the block 3 to a tranporter, transferring MeHj .aiouu-iii fuel to the consumer.

When the angle of repose of the supplied fuel is changed, the angle of the lower working position is changed: Vegvi is frightened to replace, rollers 8 with rollers of a different diameter and move them vertically to the slope. Moreover, the greater the angle ecrecTBenjioro slope material,

the greater the angle of branch elevation can be taken.

The feeder bobs bo; 1 xi (15 x 1500 x 4000 mm) is the same cross section of the nozzle 2 and the movement of the blade 4 of the pre-metering dispenser along the narrow branch of the nozzle (1500 mm), which provides the pauiioMepHbiii with the material coming out of the hopper along its entire section.

Subject invention

Feeder for iodachy bulk solids, such as high moisture humid

fuels with fuzzy inclusions, contain 1, I11 receiving pipe and a scraper dispenser installed under it with a web having | ) 1CIA1 two working branches, tensioned by means of drive sprockets and tension ro „iHKOB. This is due to the fact that, in order to adjust the angle of elevation of the lower working branch depending on the properties of the supplied material, the rollers are interchangeable with the possibility of changing in a vertical plane.
