Tubular bag type fluidized bed device for bulk powder material tank truck

Abstract

The invention relates to a material conveying device, in particular to a tubular bag type fluidized bed device for a bulk powder material tank truck, which overcomes the shortcomings of the conventional large-chute type fluidized bed device. The tubular bag type fluidized bed device comprises a chute type fluidized bed consisting of tilting fluidized bed surfaces, wherein a master air chamber is arranged below the tilting fluidized bed surfaces; each tilting fluidized bed surface comprises a fluidized bed plane, a fluidized bed slope and a lateral bevel board which are laid by fluidized bed components; the fluidized bed component comprises a hollow tube bag type air chamber which is formed by connecting an air permeation layer and an enclosed later and provided with a corrugated lining plate; and one end of the hollow tube bag type air chamber of each fluidized bed component is provided with a blast pipe communicated with the master air chamber and the other end of the hollow tube bag type air chamber is sealed by a trim strip. The fluidized bed device fully utilizes the tank space, reduces the center of gravity for car loaded, increases the load, reduces the tank capacity, increases the effective load volume; increases the fluidization area, facilitates the fluidization of the bulk materials, increases the unloading speed, and has the characteristics of convenience and safety of operation, good working condition and the like.

Description

technical field [0001] The invention relates to a material transportation device, in particular to a pipe bag type fluidized bed device for a bulk powder cargo tanker. Background technique [0002] Bulk cement truck and other powder material transport vehicles are also called tank trucks. It packs bulk cement and other powder materials in special tanks on the transport vehicles. After transporting them to the unloading site, inject compressed air into the air chamber in the special tank. Through the gas distribution plate and fluidized bed components in the special tank, the powdery materials such as bulk cement form a suspended gas-solid phase mixture in the special tank, and rely on the pressure difference inside and outside the special tank to transport the material along the pipeline to the required place. [0003] At present, in the transportation of bulk powder materials in my country's railways, the tank cars used mainly include U61W, GF18T and GF18K, etc. These cars ...
