capacity at various transport speeds of the material. The device comprises a frame 1 installed in the final section. Pneumatic transfer pipeline 3, disk 5 with shaft b fixed on it, on which bearings 9 have a housing 9 fitted with blades 10 rotated relative to the axis of the pipeline 3 at an angle of 30-60 °. Flow from the pipeline 3, the flow of the mixture gets on the blade and causes them to rotate. In this case, individual particles of the bulk material are dropped by the blades to the periphery of the filled

capacity. The drop distance is adjusted by changing the distance of the blades from the end of the pipeline 3 by setting the blades at different angles and by changing their number. The invention allows to achieve a uniform loading of the container with an intensive saturation of the material with air. In cases when the containers are filled with freshly baked flour using the proposed device, the process of ripening flour takes three days instead of the established standard - five days. 3 il.

The invention relates to the transshipment of bulk materials and can be used in the food, chemical, mining and other industries, as well as for filling containers with baking flour in flour mills when feeding flour through pneumotransport pipelines directly into bulk storage silos to obtain a flattened layer surface. flour throughout the cross section of the tank and its aeration.

The purpose of the invention is to improve the performance characteristics by uniformly filling the containers at various transport speeds of the material.

Figure 1 shows the proposed device, a General view; FIG. 2 is a view along arrow A in FIG. one; on fig.Z - section bb in fig. one.

The device for handling bulk material includes a frame 1, a compression sleeve 2, a pipe 3, an overlap of 4 loadable containers, a disk 5 with a shaft 6 and a bearing 7, between which a spacer sleeve 8, a housing 9 with a fairing and blades 10 are placed, forming a spreader and fixed in housing 9 mounting sleeves 11.

The frame 1 spreader is made of four metal rods, the ends of which are attached to the crimping cuff 2, placed on the final section of the pneumotransport pipeline 3, located in the ceiling 4 loaded capacity. The other ends of the frame bars are fixed in a disk 5 with a central hole in which shaft 6 is mounted. Dust-proof spherical bearings 7 are mounted on the shaft 7. Spacing sleeve 8 is placed on the shaft. The shaft spreader is mounted on the shaft by means of a fairing, on the base of which there are threaded radial holes for mounting the blades of the 10 spreader.

A device for handling bulk material works as follows.

A mixture of air mixture flowing out of the pneumatic conveying pipe, for example a mixture of air and baking wheat or rye flour, is directed to the blade,

The end sections of the pipe are separated by a distance of 300 mm and rotated relative to the plane of the impeller at an angle of 45 °. Under the action of the air flow blades on the blades, constituent forces are directed

normal flow and driving them into rotation. The rotating blades break up the flow of bulk material into them into individual particles, which also initially receive rotational motion in the plane of rotation, and then, under the action of centrifugal force, are thrown to the periphery. With the help of a crimping cuff, with which the spreader is reinforced in the final section of the pneumatic conveying pipeline, the distance between the mouth of the pipeline and the plane of rotation of the blades 10 can be changed. Depending on the distance in the range of 0-400 mm, the distance of the material particles from the spreader axis changes. The greater the distance between the end of the pipeline and the plane of the blades, the smaller the distance. The distance to drop material particles to the periphery also depends on the number of blades, which

fastened to the body by threading.

Pressure flow of the mixture

from the pneumatronport pipeline

provides continuous spreader action.

With the use of a spreader, an active contact of each particle occurs.

flour with air, which has a beneficial effect on the maturation process of freshly baked flour and, in turn, increases the turnover of containers.

In addition, the containers are loaded with reduced power consumption due to the absence of an electric drive, meets the fire and explosion safety regulations and ensures full utilization of the capacity of the tank.

With an increase in the turnover of flour in silos, the danger of caking is prevented. which contributes to the smooth and uniform flow of flour when cars are released into tanks, ensuring timely loading of vehicles.
