Abstract

This invention relates to pneumatic conveying of bulk materials. The purpose of the invention is to expand the operational capabilities by providing transportation of materials from two sides in the absence of mechanical impact on the material. The device contains a material-conduit 1, an air duct 2 installed inside it with oval holes 3 located along a helical line having opposite winding with respect to the axis of the discharge pipe 9. Above the air duct 2, there is a plate with guide ribs and filter barriers. The plate is spring-loaded vertically and, together with partitions, is shaken by the impact of a cam 10 made on the air duct 2. 2 Cp. f-ly, 3 ill. o (o

The invention relates to the pneumatic conveying of bulk materials, namely, a device for the pneumatic conveying of bulk materials.

The purpose of the invention is the expansion of operational capabilities by ensuring the transportation of materials from two sides in the absence of mechanical impact on the material.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. one.

The device contains a material pipe 1 with an aspiration pipe, an air pipe 2 with oval holes 3 located along a helical line with an inclination at an angle of 3-5 ° in the direction of transport, a plate 4 with guide ribs 5 and horizontal filter barriers 6 suspended from the body pipe 1 with springs 7.

The air duct 2 is connected to a source of compressed gas (for example, air) and rotates in the suspended supports 8. In the bottom of the material duct 1 there is a discharge nipple 9. The air duct 2 is equipped with a protrusion (fist) 10 rigidly fixed on it that carries hiv filtering partitions 6 and returns the product to the zone of transportation.

The device works as follows.

The product enters the material line 1 through loading nozzles (not shown). Compressed air is supplied into the cavity of the rotating air line 2, which, through the inclined holes 4 (along arrow a), rotates the material lying on the bottom of the material line I. Since the holes are located in a helical line (right or left direction), the material moves along the arrows "a, using the guide ribs 5 located on the plate 4 with an inclination in the direction of transport, direct the compressed air to Additional impact and movement of the material to the discharge pipe 9. The direction of rotation of the air duct 2 and the direction of the screw

lines for placing holes and the location of loading and unloading windows, it is possible to change the direction of transportation of the material. Located on plate 4

The filter partitions 6 suspended on the springs 7 prevent dust from entering the aspiration system, and when the air duct 2 and the cam 10 rotate, the plate 4 is shaken with the filter partitions 6 and self-cleaning from adhering dust of the transported material. The arrangement of the holes at an angle of 3-5 ° allows air to act on the material and in the "dead zones located under the suspended sub-supports.
