Description

To even out the release of grain along the length and width of the shaft, the frame of the exhaust mechanisms are divided into separate paired sections, equipped with eccentrics.

FIG. 1 shows the described dryer, a general view; in fig. 2 - view of the dryer from the loading side (without a hopper) - section A-A in FIG. one; in fig. 3 is a section along BB in FIG. in fig. 4 exhaust trays with eccentric devices and distribution chamber of the second compartment, cross section; in fig. 5 is a view along the stream B in FIG. 4, on the coupled section of the exhaust valve.

The dryer consists of trailer 1, on which two shafts are installed, equipped with boxes, respectively, recycle 2 and drying 3, between which there is a distribution chamber 4, divided by transverse partitions 5 into three compartments, two upper G and 7 of which are connected to the source of heat carrier - furnace 8, and the bottom 9 - to the atmospheric air.

A two-section bunker 10 for raw grain and bucket conveyors 11 with receiving and dispensing baimas are attached to the shafts, and a furnace 8 with which the fan 12 of the first upper compartment b is assembled on the opposite side of the dryer, the fan 13 of the second upper compartment 7, the nozzle 14 sec a blower fan 15. A fan 12 is connected via a pipe 16 to a compartment 6 of a distribution chamber 4, the upper wall 17 of which is set obliquely in the direction of the heat transfer medium. The fan 13 is connected to the compartment 7 of the distribution chamber 4, inside of which there are tapering directions 18, with upper and lower slots, tapering in the course of the coolant movement to exit the coolant to the ducts.

The discharge valve consists of moving carriages 19, reciprocating movement, and exhaust trays 20, made in the form of separate paired sections with autonomous adjustment of the output. For this purpose, lot 1-ki 20 contain eccentric devices 21, which allow the height adjustment between the planes of the carriages 19 and the trays 20.

A box with longitudinal augers 22, which are connected to the discharge auger 23, is located under the inlet carriage 19. The auger 23 has nozzles 24 and 25 for connection to the receiving shoes of the conveyors 11 and a nozzle 26 for outputting the grain.

From the dispensing shoe of the conveyor 11, the shaft 3, a recirculation gravity pipe 27 is installed, connected to the inlet pipe 2 of the conveyor shaft 2.

To return the excess grain from mines 2 and 3 to the hopper 10, additional nozzles are installed.

Describes the dryer works as follows.

Both mines are filled with grain with some excess, ensuring that it is discharged through pipeline 27 from mine 3 to

O nipple 24. Passing through the recirculation shaft 2 and compartments 6 and 7 in the shaft 3, the grain is cooled in compartment 9 and released from the dryer. The same amount of raw grain is fed to the hopper 10.

5 of mine 2. The raw grain is mixed in the nozzle 24 with recirculating gas coming from mine 3. In mine 2, the gate is set to the maximum possible transport performance of Q 11, and in mine 3 the output is adjusted depending on the humidity of the dried grain. The dryer is controlled only by feeding raw and releasing dry and cooled grain from the shaft 3.

In order to control the uniformity of heating and drying of grain over the cross section of mines 2 and 3, use the eccentric devices 21 to change the gaps between the trays 20 and the carriages 19.

In this way, this dryer provides for an autosalatic regulation of the ratio of raw and recycled grains.
