Boosting type dense-phase conveying system

Abstract

The invention discloses a boosting type dense-phase conveying system which comprises a boosting material guide pipe, a pulse material column separation cabin, an adjustable guide mechanism and a pulse air knife generator, the adjustable guide mechanism and the pulse air knife generator are located in the boosting material guide pipe and the pulse material column separation cabin, and a pneumatic boosting mechanism is arranged on the outer side of the boosting material guide pipe. One end of the boosting material guide pipe is fixedly connected with the end part of the pulse material column separation cabin, the other end of the boosting material guide pipe and the other end of the pulse material column separation cabin are respectively provided with an inlet electric control valve and a material plug electric control valve, and the input end of the pneumatic boosting mechanism is fixedly connected with a boosting air pump mechanism. According to the material plug forming device, a novel boosting structure is additionally arranged, dense-phase conveying airflow is intervened and accelerated through boosting valve pipe structures evenly distributed on the surface of the boosting material guide pipe, dense-phase conveying is accelerated and boosted through boosting gas introduced from the outside, and the material plug forming speed and the dense-phase conveying efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of dense phase conveying, in particular to a booster dense phase conveying system. Background technique [0002] Since the pneumatic conveying technology of solid materials in the pipeline began to be industrialized in the first half of the 19th century, it has been widely used in petroleum, chemical, pharmaceutical, grain, food, The transportation of powdery and granular materials exists in many industries such as electric power, building materials, metallurgy, and mining. During the transportation process, there are problems of mutual pollution of materials to the environment and the environment to materials. On the one hand, some materials are corrosive, irritating, etc. characteristics, conveying in an open state is harmful to the human body and polluting the environment, that is, the material pollutes the environment; on the other hand, some materials are easily oxidized and hygroscopic, and are transpo...

Problems solved by technology

[0004] The existing dense-phase conveying system generally adopts the connection mode of 3 tanks in series of atmospheric pressure silo, variable pressure silo and high pressure silo. The powder flows in the high-pressure silo. In the middle of the material flow, due to the consumption of the pipeline structure, the flow rate of the airflow is reduced, and the conveying efficiency is reduced. It is easy to
