Abstract

This invention relates to the gravity transport of bulk materials, in particular overloads of bulk materials through pivot tubes. The aim of the invention is to reduce the energy consumption for aspiration of the transfer device and the equipment loaded by it. This goal is achieved by the fact that in the lower part of the loading nozzle of the reloading device an aspiration opening is made, and it is enclosed in an annular sealed chamber with an aspiration suction. In addition to the loading and unloading nozzles installed partitions with a length of 3-4 their diameters. 2 hp f-ly. 1 il.

Description

The invention relates to the gravitational transport of bulk materials and can be used in the grain-processing metallurgical, construction and other industries of the national economy.

A loading device for an elevator is known, which includes a loading table with openings, shut off valves, a swivel tube, a loading hopper, a pipe for air suction, a shaft, a guide with recesses, a flange with ribs, and figured levers with rollers.

The known design of the transfer device, including discharge pipes, an annular chamber with partitions and suction suction.

However, through a reboot device, it is aspirated as equipment loaded by it, which is not working at that time, but United with it, creating a large influx of parasitic air, causing an increase in energy consumption.

The presence of baffles in the annular valve creates a system of channels with high hydraulic resistance for the passage of aspiration air, and this increases energy consumption.

The purpose of the invention is to reduce the energy consumption for aspiration of the transfer device and the equipment loaded by it by eliminating the aspiration installations servicing this equipment and their aspiration through the transfer device.

This goal is achieved by the fact that the reloading device is equipped with a second loading device attached to the lower end.

A circular lid placed at the level of the bottom wall of the annular chamber, made with a hole along the diameter of the filling nipple, in the cavity of the Evolutionary portion of which a vertical partition is installed, the upper end of which is fixed to the nipple and the lower end is located at the level of the second annular cover, far from the axis rotation of the pipe wall of the latter in the area between the first and second lids aspiration hole is made, with each discharge pipe equipped with its own vertical partition, erhny end of which is placed at the discharge end of the nozzle, with no sovmesche- the lower end of vertical partition boot tube and placing it in a single plane when setting the latter on the corresponding discharge pipe.

The drawing shows the device, the overall appearance.

The transshipment device consists of a distribution table 1, to which are fixed along the rotation trajectory of the loading nozzle 2 using axis 3, the support collar 4 and the drive wheel 5, discharge pipes 6, the upper part of which coincides with the plane of the table 1 and forms in it 7 inlets, which are sealed to prevent air suction from inoperative equipment using an annular cover 8 fixed to the bottom of the loading nozzle 2. Two cylinders 9 and 10 are rigidly fixed to the distribution table, the upper part of which groove 11 is made so that another ring cover 12 is movably installed therein, so that between the covers 8 and 12 and the cylinders 9 and 10 there is formed a sealed annular chamber 13, to which is attached an aspiration suction 14. At the bottom of the boot A nozzle 2 enclosed in the chamber 13 has an aspiration hole 15 through which the equipment 16 is dedusted by the distribution flow.

To prevent the grain from being sucked into the suction in the loading 2 and discharge pipes b, solid partitions 17 and 18 are installed parallel to the rotation path of the pipe 2, the length of the partition 18 is equal to 3-4 diameters of the loading outlet, and the partition 17 is limited by the inclined inside surface of the discharge 2. 12 to the surface of the distribution table 1 on the inner surfaces of the cylinders 9, 10, support rings 19 are rigidly mounted under the cover 12, forming a guide channel for moving the cover 8.

The device works as follows.

Boot nozzle 2 is provided in

rotation is mechanically or electrically driven and is set to the required position in accordance with the required route of movement of the cargo and

0 processing technology.

After installation of the nozzle 2 so that its inlet opening coincides with the inlet of one of the unloading nozzles, bulk material flows through the nozzle 2 and through the unloading nozzle 6

5 is loaded into the equipment 16. The dusty air generated in the equipment 16 is aspirated by the aspiration unit 20 through the discharge port 6, the opening 15 in the charging port 2 and the annular channel 13 to the suction outlet 14.

Claims (3)

Thus, the proposed design allows to aspirate only the equipment that is loaded with a reloading device, which allows to avoid parasitic air flow and significantly reduce the energy consumption of the dedusting system of the rotary tubes. Claims 1. Device for handling bulk solids 0 material, containing a housing with circumferential discharge nozzles, communicated with the air ducts of the aspiration system and an annular chamber enclosing along the perimeter body, mounted above it with the possibility of rotation around the vertical axis of the loading nozzle with inclined and vertical sections and attached to it at the top wall level camera ring cover 0 with an opening through which the lower end of the loading nozzle is passed, characterized in that, in order to reduce energy consumption, it is provided with a loading nozzle attached to the lower end of the loading nozzle 5 and a second annular lid placed at the level of the lower wall of the annular chamber, made with a hole in diameter of the inlet nozzle, in the cavity of the vertical portion of which an aperture partition is placed fixed with the upper end on the nozzle and the lower end is placed at the level of the second annular lid, far from the rotation of the nozzle to the wall of the latter in the area between the first and second lids is aspirated hole, while the discharge nozzles each is equipped with its own vertical partition, the upper ends of which are placed at the level of the lower end of the loading nozzle with the possibility of combining the ends of the partitions of the unloading and loading nozzle when the latter is installed above the corresponding unloading nozzle. 2. The device according to claim 1, characterized by the fact that in each discharge pipe the partition is installed in diameter and has a length of at least three and no more than four diameters. 3. The device according to claim 1, characterized in that the aspiration hole is made with an area equal to the cross-sectional area of the loading nozzle. V7 20
