Description

(54) TAKE A HANDLING OF THE BULK MATERIAL

I

This invention relates to the transport and dedusting of bulk materials.

The shelter of bulk material transfer points is well known, which contains a tank and an outer box with sealing aprons, in which the inner box with a partition is located.

A disadvantage of the known device is the presence of a large gap area between the small partition and the material transported on the tape, which leads to the low cost effectiveness of the said shelters due to the need to remove a large amount of air from the shelter when using aspirases. In addition, the bulk material after loosening to the tape is in a loosened state and, when it leaves the shelter, is dusting due to the vibration of the tape from moving along roller supports and the mobility of the surrounding air.

The aim of the invention is to prevent the dusting of the material.

This is achieved by the fact that the partition in the lower part is equipped with an under-roller, 9 in the upper - with counterweights.

FIG. 1 shows the proposed shelter for bulk material transfer sites; in fig. 2 is the same, view from A-A in FIG. 1.

To the chute 1 and to the frame of the conveyor 2 is attached an external box 3 with an aspiration funnel.

On the duct 3, the aprons 4 are fastened (rubber seals 5 around the perimeter. Inside the outer duct 3 to the chute 1 n), and the inner duct 6 has 6 with 6aMnacoN 7 and a seal 8 along the lower perimeter. From the side opposite to estrus 1, in lateral creimax. The inner box 6 is fixed under the vigorous rigid partition 9, on the underside of which the roller 1O is fixed with the possibility of free rotation and displacement along the height in the inner box 6 when in contact with the slide with conveyor belt or material on it.

To the partition 9 are attached counterweights 11.

The process is performed by the slaad.

With a conveyor belt 2 without material, the roller 10 adjoins the conveyor belt 2, and the partition 9 closes the cross section of the inner box 6, which is aerodynamically connected with chute 1, which prevents excessive leakage of air through the chute 1 into the outer duct 3. At 11adeg the material and the air ejected from it from the chute 1 to the conveyor belt 2, the roller 10 and the partition 9, lift, pass the material. - and separate the air flow from it.

The pressure generated by the ejected air in the inner box 6 and permits; 4iejfue iodine with an external duct 3, created by a non-injector, through the leaks of the inner cyro 6, partially select the ejected outer duct 3, which is unn. by the fan, and partly according to the BGSA 7, it returns to the heat 1 for the new IOiJHOii ejection

four

The roller 10, under its own weight and counterweights, rolls the bulk material, which helps to reduce dust emission from the surface of the material behind the cover 5 when the tape vibrates on roller bearings and from the tape movement and air flow of the surrounding air.

Subject invention

The shelter of bulk material transfer points containing the chute and the outer box with sealing aprons, in which the inner box with a partition is located, is characterized in that, in order to prevent dusting of the material, the partition in the lower part is equipped with a movable roller, and in the upper part with counterweights.
