Description

The invention relates to equipment for oil and fat industry and can be used in the processing of sunflower seeds.

The purpose of the invention is to improve the quality of processing by equipping the device with air ducts installed along the inner wall of the rotating sieve and connected to the cyclone and the fan, allowing to separate the husks and oil dust from the Ruschanka, as well as to prevent clogging of the sieve.

Ya FIG. 1 shows the device, a general view in section; in fig. 2 is a section A-A in FIG. one; FIG. 3 is a section BB in FIG. one.

The device for breaking oilseeds consists of vertically. of the cylindrical body 1 with the deck 2 coaxially mounted therein.

In case 1 a vertical drive shaft 3 is reinforced, on which one is reinforced under one another with the possibility of

rotation cylindrical screen 4 and working disks 5 in which radial guide channels 6 are made.

A distributing device 7 is located above the working disks 5, and a device for collecting oil dust is mounted in the lower part of the body, which includes a cylindrical sieve 4 with ducts 8 connected with chutes 9 for removing husk.

In the lower part of the body, the chute 10 is placed to drain the cleared Rushanka. Along the generatrix of the inner surface of the cylindrical screen 4, diametrically opposed fixed ducts 11 are placed in pairs, connected to the cyclone 12 and the fan 13.

The box 8 is located along the generatrix of the outer surface of the cylindrical screen 4 also in pairs and diametrically opposite. In addition, each box 8 and duct t1 is located

wives with displacement relative to each other in such a way that their bore sections do not overshoot.

Along the inner surface of the cylindrical screen 4, cleaners t4 can be installed, and the casing 1 can be equipped with an annular gap 15, covered by a shield 16 and located at the level of the upper end of the cylindrical screen 4.

The size of the flow area of the annular slit 15 can be adjusted by moving the shield 16.

The device works as follows.

The oil-containing material is fed in an uninterrupted flow to the distributor 7, from where it enters the mixture into the guide channels 6 of the discs 5. Under the action of centrifugal force, the material flies out of the channels 6 and hits the deck 2.

The ramming due to the acquired speed and the directed air flow created by the rotating disks 5 moves in a spiral along the wall of the housing 1i, as a result of which the riverbank separates according to the density of its particles. which contributes to a better separation of husk and oil dust. At the same time, the flap 16 prevents the release of the riverbank. The cylindrical screen 4 rotates in the same direction as the working disks 5, which ensures the directed movement of the air flow in the housing 1. The oil dust and husk are entrained by the warm air that penetrates the screen 4 due to the vacuum generated by the fan 4 in the screen 4. air flow should not exceed the critical speed of husk husk and oil dust (4.0 m / s). The oil dust passes through the holes of the sieve 4 and is discharged into the cyclone 12 through the air ducts 11, and the husk is held

on the surface of the screen 4 and moves with it to the boxes 8 to remove the husk, where under the action of centrifugal force and in connection with the absence of air leaks, the husks are thrown into the boxes 8 and diverted through the chutes 9 dp of the husks. The cleared ruschanka is diverted by chutes 10.

The cleaners 14 clean the inside surface of the sieve 4 from adhering particles and release particles stuck in the holes. An adjustable annular slot 15 allows the incandescent layer of the incoming stream to be inflamed with a jet of drawn air.

The flap 16 prevents the release of the riverbank from the housing 1.
