Description

(5A) CONSUMABLE BUNKER FOR MATERIALS CONVENIENTLY CONTAINED The invention relates to consumable bins for storing and unloading hard-flowing materials prone. for caking and arching, and intended for use in the food, chemical, construction and other sectors of the national household. The feed bin for materials prone to arching is known, comprising a housing with a system of nozzles that are placed on the conical part of the housing, and the nozzles are connected with a source of compressed air JV. The disadvantage of such a device is the low efficiency of the co-collapse due to its limited area of operation. Also known is a feed bin for materials prone to arching, comprising a housing within which there is a rotating material flow booster made in the form of a hollow shaft with nozzles attached to it, connected to a source of compressed; air, at this; ohm, the hopper shaft is connected to a gearbox and an electric motor G2 3. The disadvantage of such a feed bin is that the rotation of the shaft requires the use of an additional mechanical drive, which complicates and increases the cost of the device, rior increases energy costs. The aim of the invention is to accelerate the process of de-abrasion and simplify the design of the device. To achieve this goal, in a known feed bin for materials prone to arching, comprising a housing, inside is a rotating material flow booster, made in the form of a hollow shaft with nozzles attached to it, connected to a compressed air source, each nozzle nozzle made of arcuate elastic material and

it is equipped with a swirler installed in it. The swirl is made in the form of a spiral.

FIG. 1 (iz6 | eazhen feed bunker, general view; fig.2 - view a in fig.1; figa3 - a section of the nozzle t fragment).

The feed bin comprises a housing. 1, rotating material booster 2. The booster 2 is made in the form of a hollow shaft k mounted on bearing supports 3 with arcuate nozzles 5 fixed on it in the radial direction and fitted with a swirler 6, for example, in the form of a wire helix over its entire length.

Nozzles 5 nozzles can be made with an elastic deformation capability along the entire longitudinal axis and are made of an elastic material, such as reinforced rubber.

The input part of the axis of the nozzle nozzles 5 is close to the tangential circle and provides the reactive torque to the shaft from the compressed air source.

The shaft t is connected to the source 7 of compressed air.

The device works as follows.

Air from the compressed air source 7 is supplied to the hollow shaft, from where it enters the nozzle nozzles 5, is twisted into them by a swirler 6 in the form of a wire helix, and is pulled out into the material, causing it to turn and torque to the shaft k, which starts rotate with the nozzles in the direction opposite to the outflow of air from the cogel.

The increase in torque to the shaft is provided by increasing the air pressure at the nozzle outlet by estimating a partial conversion of the kinetic energy of the vortex flow into static pressure. This causes an increase in the speed of rotation of the shaft and the intensity of the tedding. In addition, the vortex movement of the air escaping from the nozzle also contributes to the intensification of material loosening.

In the case of the implementation of nozzles 5, with the possibility of elastic

deformations along their longitudinal axis, i.e. flexible, with walls made, for example, of reinforced rubber, the latter, when rotated, will partly

rectified, which increases the range of the Enhancer. In this case, in the absence of arching, the nozzle-nozzles 5 rotate with a minimum radius and speed due to the high resistance of the material, and when a dome hangs above the material stimulator, the shaft rotates and the nozzle 5 increases as a result of a sharp drop in the resistance The centrifugal and elastic forces are spread all the way from the arch and destroy it with jets of turbulent air and blows of the nozzles' mass against the arch.

In the supply bin as a drive, shaft C, a source of 7 compressed air is used, at the same time compressed air creates effective loosening of the material.

The constructive implementation of the nozzle-nozzle arcuate of an elastic material and the use of a swirler accelerates the process of collapsing difficult-flowing material in the feed hopper.
