Description

one

The invention relates to the storage of bulk materials and can be used in the building materials industry and other sectors of the national household.

A known hopper for bulk material, comprising a housing with a bottom inclined toward the discharge opening and a gate lj rotatable around a horizontal axis.

The disadvantage of this bunker is that it does not ensure uniform distribution of the layer of granular material across the grain size distribution over the width of the chute and its uniform unloading.

The purpose of the invention is uniform material unloading.

The goal is achieved by the fact that the hopper for bulk material, comprising a housing with a bottom inclined toward the discharge opening and a gate rotatable around a horizontal axis, is provided with a divider having a D-shaped working surface in contact with the back along the material movement and associated with the latter and bottom cone-shaped

 surface facing the discharge opening. In addition to Togo, deflectors on the bottom of the bunker are attached to the side walls of the dissector.

In Fig.1 schematically depicts a bunker, front view; in Fig.2, view A in Fig.1.

The bunker consists of a body 1 formed by side walls 2, a rear wall 3 and a bottom 4, on which a divider 5 is fixed, having an L-shaped working surface 6 in contact with the material moving backwards and a cone-shaped surface 7 contacting with the bottom. facing the discharge opening. On the bottom 4 there are fixed deflecting peaks 9 adjacent to the side walls of the dissector 5.

The hopper has a bolt 10 with dynamometric springs 11, the force of which is adjusted by bolts 12 mounted in brackets 13.

The bolt to is fixed in the brackets 14 fixed to the housing 1. The housing 1 has a front wall 1

The bunker works as follows. The material is fed into the bunker at the center of the splitter, thus forming a continuous flow of material at 5 cone-shaped surface 7 and side surfaces 6. Partially changing the flow in the direction due to the action of the visors 9, the fine material is averaged with large, accumulated

10 against the walls 2 by the action of repose, and rushes towards heat. Under the action of the gravity of the bolt 7 and the torque springs 8, the material is held and aligned with an equal layer and flows through the slit of the bolt 10 across the entire width and with an equal layer through the thickness.

The principle of operation is as follows.

20 Rolling along the cone-shaped surface 7, the material is distributed over the width of the base of the surface 7 with an equal layer in thickness and particle size distribution;

 on the bottom 4 bunkers. According to the surface planes 6, the material is divided into two equal parts by volume and particle size distribution and rolls onto the bottom 4 of the silo. At the same time near

30 of the walls 3, partial crumbling of the material is formed, which is inclined at an angle of repose. To obtain a uniform layer of material on the particle size distribution

35, the fine material, when sliding on the bottom 4, is retained by the visors 9 and guided towards the side walls 2 for averaging the coarse material. Further movement of the material on the bottom 4 is carried out under the force of gravity of the pieces of material that, due to sliding friction, occurs due to the installation angle of the bottom 4, taking into account

45 sysyvstv material of interacting bodies.

The proposed bunker design will allow to increase the productivity of the process equipment (screen) by 20-30%, depending on the type of screen. This is due to the fact that with the current method of loading the screen using trays, the material is fed to the screen by a narrow layer in the center of the screen, forming a multi-layer embankment. Then the material under the action of vibration and slope

the sieve spreads, leaving the corners of the sieve unused. Placement over the entire width of the screen begins at a considerable distance from the loading point. And this leads to the fact that with a thin bed of rattling material, the selection begins at a distance of 30% of the length of the screen from the loading point, and with a thicker bed, the selection begins at a distance of 40-50% of the length of the screen. This leads to a large loss of the working surface of the screen and, consequently, to

View

decrease in productivity and screening efficiency. With a high degree of uniform use of the entire working surface of the screen by loading, uniform wear of the screens is achieved, which eliminates the additional cost of repairing the screens. And with a constant productivity of use of the loading device (bunker) it allows the use of a smaller screen size, which provides additional savings in equipment and electricity costs.
