Description

The invention is related to the mining industry, namely, to devices for averaging the quality of ores of explosive grades and coal of various ash grades and can be used in the development of minerals by open or underground mining in land complexes of mining enterprises.

A device for averaging the quality of ores and coals, which includes a receiving tank and a discharge body, is known.

However, the device does not provide sufficient averaging quality, has low productivity and complexity.

 The closest to the invention to the technical essence and the achieved result is a device for averaging the quality of solid bulk materials, including a receiving tank consisting of a storage unit and a loading unit, and a discharge body f 2 ..

A disadvantage of this device is that the efficiency of the process of averaging solid bulk materials in the process of gravitational transfer is low due to single mixing.

The purpose of the invention is to increase the homogeneity of the mixture of different-quality solid bulk materials by repeatedly1 about mixing them during gravity transport.

This goal is achieved by the fact that the device, which includes a receiving tank consisting of a storage device and a boot node, and a discharge

10, the body is equipped with a mixer, made in the form of inverted truncated pyramids, mounted one above the other and placed between the two-fold dividers, with the bottom

15, the truncated pyramid is connected to the unloading unit, and the hopper is provided with a shield mounted vertically in it with the possibility of movement in the horizontal and vertical plane of the bone.

In addition, the longitudinal axis of the accumulator, the dissector and the discharge body are located in the same vertical plane.

FIG. i shows the proposed device, a general view, in section,

in fig. 2 shows a shield in the storage unit. FIG. 3 - drive with ver30

tix board inside view from above.

The device contains a receiving tank 1, the state of 1 of the accumulator 2 and the load-3. In the accumulator 2 there is a shield 4: which is fixed on the drums 6 by means of horizontal cables 5. The drums 6 are mounted on shafts 7 mounted on bearings 8. Spacing beams 9, connecting shafts 1, with vertical cables 10 are connected to the ba | Abans 11, sitting on the shaft 12, which is fixed horizontally, in the middle of the drive 2. The loading unit 3 consists of a slab 13, in which boot hatches (not shown) are made above the opposite ends of accumulator 2. The mixer consists of inverted truncated pyramids 14 and double-slope spreaders 15. Lower inverted truncated 14 soy pyramid, dinene with discharge body 16 ..

The device works as follows.

Solid bulk materials of different qualities (for example, ore, coal) are fed to storage device 2 via loading unit 3 by means of mountain transport, for example, by autotrucks 17, which; they call in on the slab 13 and unload alternately in the loading hatches. After unloading the dump truck 17, the drums b are turned on, setting up a shield 4, mounted vertically on drive 2 by means of horizontal cables 5. During the movement, SHIELD 4 transforms a bulk pile of solid bulk material into layer 18, evenly distributed over the area of drives 2, the storage device 2 solid bulk material includes drums 11, whereby the position of the shield 4 is adjusted in height in the vertical plane, since the amount of winding of the drums 11 corresponds to the length of the layer 18 solid Wow loose bulk material. After the accumulator 2 is filled with bulk material and the average grade of solid bulk material is spun, the bottom 19 of accumulator 2 and a different-quality layer laminate mass rushes into the mixer, and, displacing during the gravitational transport, the flow of solid bulk material At first, the double-sloped divider 15 passes, and then, hitting the steaks with inverted yc € Jchen feasts; 1f1 14, goes to the lower slider 15. Passing the mixer, solid loose material, accumulator with the bottom perever | mentioned truncated pyramid moIenta 14 to discharge into the vehicle ,, for example a railway carriage 20 (the direction of movement of particulate TBE |) dogo material through the mixer is indicated by arrows.

After the accumulator 2 is unloaded, its bottom closes and the averaging process starts again.

Compared with the known device, the proposed has the following advantages.

. Installing the shield in the accumulator, with the possibility of moving in the horizontal plane, allows the initial averaging of the solid bulk material in layers.

The use of a mixer in the device, made in the form of inverted truncated pyramids, placed under each other and placed between the two-fold dividers, allows mixing in the process of averaging the quality of solid bulk material during gravitational transportation.

The arrangement of the accumulator, the dissector and the discharge body, so that their longitudinal axes are in the same vertical plane, ensures uniform mixing of the entire flow of solid granular material at the moment of passage of the mixer.

The connection of the discharging device of the device with the lower inverted truncated pyramid of the mixer allows to reduce the vertical dimensions of the device while at the same time allowing accumulation of a large volume of bulk material.
