Description

one

The present invention relates to devices for transporting various bulk materials and pre-mixing these materials.

Devices are known for transporting bulk materials, including a chamber equipped with a loading gate, a material line, an air line for supplying compressed air, and a device for venting air into the atmosphere.

However, these devices do not pre-mix several components of the bulk material.

The proposed device for transporting bulk material is provided with a chamber, in the upper part of which at least one conical screen is mounted, and the material pipeline with a recirculation pipe is connected to the chamber.

The drawing shows a general view of a device for transporting bulk material.

The proposed device for transporting bulk material is made in the form of a cylindrical chamber 7, the internal cavity of which is divided into compartments by two truncated conical screens 2. In the lower part of the chamber, an air duct 3 is installed, a conduit 4 with a recirculation pipe 5.

In the upper part of the chamber 1, a loading valve 6 is installed with air filters 7 and 8 communicating with the atmosphere.

The upper and middle compartments are interconnected by a tube 9.

A device for transporting bulk material works as follows.

The bulk material components are loaded into the chamber through the loading shutter 6. After the filling of the material has been filled, the shutter is closed. The conical screens 2 n of the loaded material inside the chamber form air cavities which, through the air tube 9 and the filters 7 and 8, communicate with the atmosphere. Before transportation, mixing of the bulk material components takes place. The mixing takes place when the material components are moved from the lower part of the chamber / along the recirculation pipe 5 to the upper part of the chamber and the further movement of i along the tapered screens 2 downwards.

In the upper part of the chamber, connected to the atmosphere through the filter 7, barometric pressure is created, and in the lower part of the chamber an aerosol pressure is created. The movement of the air mixture into the recirculation pipe 5 occurs if a pressure difference is created between the upper part of the chamber and its lower part, and if the resistance of the air passing through the bed of filled material in the chamber is greater than when passing through the recirculation pipe 5.

When the material components are mixed through the airway 3, air is supplied to the lower part of the chamber, valve 10 at the recirculation pipe 5 and valve 11 are simultaneously open for communication with the atmosphere, and valve 12 at the material wiring is closed.

The resulting aerosol rushes through the material line 4 with the recirculation pipe 5 into the upper compartments of the chamber. At the same time, the various components are mixed and then moved down, and the air is released through the filters 7 and 5 into the atmosphere.

After the materials are mixed, the valves 10, 11 are closed and the valve 12 of the material pipe 4 opens. The pressure in the chamber is equalized and conditions are created to move the slurry along the material line 4 to the place of discharge.

Subject of invention

A device for transporting bulk material comprising a chamber equipped with a loading gate, a material line and air lines for supplying and discharging compressed air, characterized in that, in order to provide a preliminary displacement of several bulk material components, at least one conical screen is simulated, over which a recycle pipe is installed, is connected to the material pipe.
