Description

(5) SEPARATOR FOR SEPARATION OF POWDER-SHAPED

MATERIALS

one

The invention relates to devices for the separation of a mixture of powdered materials and may find application in the chemical, energy and other industries.

A separator is known that includes coaxially mounted housings with a radial hand-cutting device located on the lid of the outer casing, as well as an outlet branch pipe adapted for axial displacement for adjusting raceways | one .

The disadvantage is the low quality of separation and a decrease in its efficiency when moving the outlet nozzle relative to the optimal, average position. Raising the outlet nozzle causes large particles to contaminate the finished product, and lowering increases the content of fine dust in return.

N. most similar in technical essence and the achieved result

We offer a separator comprising coaxial cylindrical-conical bodies with lids, rotating blades mounted between the bodies, placed around the entire perimeter of the body, loading and unloading devices 2 J.

However, the device has a low separation efficiency due to the lack of possibility of change in

10 wide range of size of the finished dust produced by them. In this apparatus, the regulation of the size of the dust is carried out only by changing the angle of rotation of the blade apparatus.

ts

The purpose of the invention is to increase the separation efficiency by adjusting the particle size of the dust.

The goal is achieved by the fact that the separator is equipped with rods,

20 mounted on the lid of the inner casing and a fixture for moving the pull g located on the lid of the outer casing. The drawing shows a diagram of the device. The separator includes an outer casing 1 with a lid 2 and an inner casing 3 mounted coaxially with it with a lid k, which is attached by means of 5 with the help of tool 6, for their movement in a vertical direction, to the lid 2 and oGpaa vc: with an inner cone, an annular slot 7 Adaptation 6 for adjusting the values of r 5 can be performed, for example, in the form of a screw pair. The caps 2 and form a separation zone 8. An axial twisting device of a blade 9 of which can simultaneously rotate around its axes 10 is installed between the cylindrical parts of the bodies, using a rotary mechanism 11. In the lower part of the body 1 are located the inlet 12 for supplying the initial material to be divided and the leak 13 for removing the primary separator. To the top cover 2 is attached an outlet for removal of gases together with the finished dust, and in the lower part of the inner case 3 - chute 15 for removal of the secondary separator. The separator works as follows. The material to be separated with a gas flow through the inlet 12 goes into the space between the housings 1 and 3, where under the action of gravity and inertia the largest particles are separated and enter the chute 13. Leaving the dust with the gas flow is carried into the spatula, twists The blades 9 and enters the separation zone 8 formed by the covers 2 and t, where under the action of the center, the beating forces are separated. Small particles together with the gas are carried to the nozzle, and the large ones are partially thrown to the inner wall of the outer case, subjected to repeated separation, and partially fall into the annular gap 7 formed by cover C and case 3, and then into the drain 15. By moving the cover k in height with the help of tg 5 and adjusting 4 of the standard 6, the coarse adjustment of the fineness of the finished dust is carried out, the approach of the cover k to the cover 2 causes the dust to coarsen, and vice versa, by rotating the blades 9 around the axes 10 by a common turning mechanism 11 the ducks flow in the separation zone and fine adjustment of the size of the finished dust, the proposed device allows you to change the height of the separator zone between the covers, and hence the speed of the dust-gas mixture in the radial direction and the fineness of the dust produced by the separator, i.e. make a rough adjustment of the separator. Fine tuning to the desired mode is done with a blade apparatus by changing its angle of rotation in the range (from the vertical direction), ensuring the most effective separation. Claims Separator for separating powdered materials, including coaxially arranged cylindrical bodies with lids, turn-i blades placed between the cases, placed around the entire perimeter of the case, loading and unloading devices, characterized in that, in order to increase the separation efficiency by adjusting the size dust, the separator is equipped with rods mounted on the lid of the inner case and a device for moving the rods located on the lid of the outer enclosures.
