Description

FIG. g

The invention relates to pneumatic transport and can be used in the chemical, food, pharmaceutical and other industries.

The purpose of the invention is to increase reliability ;: work.

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

The device comprises a hopper 1 with an outlet 2, a blade rotor 3 mounted in supports 4, and a guide 5. The blades 6 of the rotor 3 are made in accordance with the profile of the lower part of the horizontal section of pipeline 6 and have a width equal to the diameter of the outlet 2 combs of rods 8, offset from each other. The forward plate 5 of the guide 5 is arranged with a gap 9 relative to the wall of the horizontal section of the pipeline 7, and the rear 10 has a rotor blade profile and is perforated.

The device works as follows.

The material from the bunker is supplied through the outlet 2 to the horizontal section of the pipeline 7. The air flowing around the guide 5 interacts with the blades of the rotor 3. Since, due to the presence of the guide 5, the air only acts on the blades located above the axis of rotation, this leads to intensive rotation of it in the supports 4. Non-agglomerated particles of the material are picked up by the flow and transported along the horizontal section of the pipeline 7. The rods 8 are displaced one against the other, which eliminates the entry of particles wet material on the rear wall 10 of the guide 5.

The axis of rotation of the vane rotor 3 is in the same vertical plane with the rear edge of the outlet 2. With

This arrangement of the axis of rotation causes the particles interacting with the rods 8 to be accelerated upwards and in the direction of flow. The height of the blades 6 is equal to the diameter of the outlet, which provides dehydration of the agglomerate leaving the outlet.

Claims (1)

Invention Formula 0 A device for inserting bulk materials into a horizontal pneumatic conveying pipeline that contains a hopper with an outlet and is fixed to the bottom parts of the pipeline under the bunker, the device for loosening the material, characterized in that, in order to increase the reliability of operation, the device for loosening the material is made in the form of a vane rotor, the shaft of which is located horizontally in a vertical plane passing through the rear air mixture to the edge of the outlet, and the blades of the working surface correspond to the shape of the surface of the pipeline 5 and in its middle part, overlapped in terms of the outlet, are made in the form of combs, the rods of which are displaced along the axis of the rotor shaft relative to each other and are made with a length equal to the diameter of the outlet of the bunker, 0 this device is equipped with a guideway installed in front of the rotor downstream, consisting of two curved plates connected to form an apex angle at the level of the rotor shaft, one of which, rear downstream, is fixed 5 in the pipeline with its free edge and perforated with a profile that repeats the profile of the rotor, and the other is installed with its free edge with a gap relative to the pipeline.
