Positive-pressure pneumatic conveying system for particle dust

Abstract

The invention discloses a positive-pressure pneumatic conveying system for particle dust. The positive-pressure pneumatic conveying system comprises a device body, the device body comprises an air blower, a mixing device is arranged on one side of the air blower, the mixing device comprises a mixing box, the side wall of the mixing box is connected with the output end of the air blower in a penetrating mode, the top of the mixing box is connected with a feeding box, and the inner wall of the feeding box is slidably connected with a feeding plate; a driving assembly is arranged on one side of the feeding plate, a cyclone separator is arranged on one side of the mixing box, a pipeline device is arranged between the cyclone separator and the mixing box, the bottom of the cyclone separator is connected with a material bin, the pipeline device comprises two straight pipes, the two straight pipes are connected with the mixing box and the cyclone separator respectively, and two connecting assemblies are arranged on each straight pipe; and two bent pipes are arranged among the four connecting assemblies, and a sliding assembly and a sealing assembly are arranged on the side wall of each straight pipe and located between the two connecting assemblies. According to the conveying system, the air mixing ratio of materials in a conveying pipeline can be controlled, the bent pipes are convenient to maintain and replace, and the conveying system can still continue to work when the bent pipes are replaced.

Description

technical field [0001] The invention relates to the technical field of dust transportation, in particular to a positive pressure pneumatic transportation system for granular dust. Background technique [0002] Granular dust can be transported by air force, which uses the energy of air flow to transport granular materials along the direction of air flow in a closed pipeline. [0003] According to the pneumatic conveying system for mixed dust in the iron and steel industry provided by the patent literature with the application number CN201620993646.9, it can be known that the product includes a fan, a pressure transmitter, a pneumatic conveying pump and an ash storage bin. The device, the pneumatic conveying pump and the ash storage bin are connected through a wear-resistant conveying pipeline, and a venturi tube is arranged on the wear-resistant conveying pipeline between the pneumatic conveying pump and the ash storage bin. The structure of the product is firm and wear-resi...
