Problems solved by technology

[0004] However, in the actual transportation of ultrafine powder, the wall sticking phenomenon still inevitably occurs, especially in the long-distance transportation, the material loss is more obvious, although it is far less than the traditional mechanical transportation, it still cannot be ignored

Abstract

The invention relates to a horizontal long-distance superfine powder pneumatic conveying device which is connected with previous-level feeding equipment and used for long-distance conveying of superfine power and toxic or corrosive materials. The horizontal long-distance superfine powder pneumatic conveying device comprises an air source machine, a working cabin, a material conveying pipe and a controller with a CPU (central processing unit), wherein the air source machine consists of an air storage tank, an air compressor and a fan, a material inlet is communicated with the working cabin andcontrolled by a first valve, one end of the material conveying pipe is communicated with the working cabin and controlled by a second control valve, the other end of the material conveying pipe is communicated with a separator, n segmental control valves are uniformly distributed on a horizontal section of the material conveying pipe, an air pipe with three branches is arranged on the air storagetank and is respectively communicated with the working cabin and a rotary sweeping and conveying device, the working cabin is communicated with the air storage tank and is controlled by a fourth valve, the rotary sweeping and conveying device is communicated with the air storage tank and controlled by a fifth valve, material is fed into the separator and discharged from a material outlet and the material outlet is controlled by a third valve. The horizontal long-distance superfine powder pneumatic conveying device is in a segmental suction type pneumatic conveying mode, the material is pressed segment by segment, and the conveying loss of the material is less than 20g.

Description

technical field [0001] The invention relates to a pneumatic conveying device, in particular to a horizontal long-distance ultrafine powder pneumatic conveying device, which uses a sealed conveying pipeline and is suitable for long-distance conveying of ultrafine powder, toxic or corrosive materials. Background technique [0002] At present, the ultra-fine powder conveying devices used by most domestic enterprises are mostly mechanical conveying devices such as belt type or screw type. However, the belt conveying device has poor sealing performance, and the material is easy to fly when conveying ultrafine powder, which will cause serious dust pollution, and it is impossible to convey toxic or corrosive ultrafine powder, and the cost is also high. Multiple units are required to be used in combination; the sealing performance of the screw conveying device is better than that of the belt type, but during the transportation process, there is friction between the material and the ...
