Description

one

Known sieving, containing the frame, the oscillator, located under each other inclined sieves connected by vertical channels with a distribution device, and the discharge device is.

In order to increase productivity, the proposed distribution device is designed as a tank with a perforated bottom, under which are vertical channels formed by partitions, the number and width of which corresponds to the number and width of the inclined screens.

FIG. 1 shows the proposed screening plan; in fig. 2 - the same, side view; in fig. 3 - distribution device in a perspective view.

The seeding includes a carriage of the bodies / and 2 and according to: with the beams 3 and 4, a frame with a oscillator made in the form of a vertical shaft 5 with unbalances 6. Each body is a full metal container in which H1 inclines are mounted one above another sieves 7 mounted on wooden frames 8. Under sieves 7 there are mounted sieves 9 with large cells for placing rubber balls 10. The loading edges of the sieves are staggered relative to each other in the direction of the vertical channels.

The distribution device // made in the form of a tank with a perforated bottom 12, under which are located the vertical channels 14 formed by partitions 13, the number and width of which corresponds to

the number and width of the inclined sieves. The holes in the perforated bottom 12 are arranged in parallel rows, the number of which corresponds to the number of vertical channels 14. The unloading device for removing the upper and lower products is made in the form of funnels 15 and 16 located in the lower part of the bodies 1 and 2. The seeding is suspended to the building ceiling on the ropes 17

Original product such as rough

the asbestos concentrate is fed to the distribution device 11, where it is sifted through the rows of holes in the perforated bottom 12 under the influence of vibrations, is evenly distributed along the vertical channels 14 and then goes to the sieve 7 across their entire width. When the top product leaves the screen, it enters the top inclined plane of the chute 18, from where it enters the vertical discharge channel formed by the walls 19 and is removed through the funnel 15. The bottom product, moving along the inclined solid bottom 20, is divided into two flow, enters the vertical discharge channels with stems 19 and 21, and

0 is removed through the funnels 16.

Parallel loading of screening screens ensures a uniform height of the product layer over their entire area, and, consequently, high sifting efficiency. Due to this, it is possible to increase the size of sieves.

Subject invention

Sieving, containing frame, oscillator, sloped under each other

sieves connected by vertical channels (, mi with a distribution device, and a discharge device, characterized in that, in order to increase productivity, the distribution device is designed as a tank with a perforated bottom, under which vertical channels formed by partitions are located; the number and width of the inclined sieves.
