Booster Dense Phase Conveying System

Abstract

The invention discloses a booster dense-phase conveying system, comprising: a booster material guide pipe, a pulse material plug compartment, an adjustable guiding mechanism and a pulse air knife generator located inside the booster material guide tube and the pulse material plug compartment The outside of the booster guide tube is provided with a pneumatic booster mechanism, one end of the booster guide tube is fixedly connected to the end of the pulse plug compartment, and the other end of the booster guide tube and the pulse plug compartment are both There are respectively imported electric control valves and material plug electric control valves, and the input end of the pneumatic booster mechanism is fixedly connected with a booster air pump mechanism. In the present invention, by adding a new type of booster structure, the booster valve tube structure evenly distributed on the surface of the booster guide tube is used to intervene in the dense-phase conveying airflow, and the conveying airflow is accelerated, and the booster gas is injected through the outside. Dense-phase conveying is used for acceleration and boosting, which improves the speed of plug forming and the efficiency of dense-phase conveying.

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 cause blockage, and the powder in the material plug forming cavity cannot be pushed by the high-pressure gas. Dense material plug structure, under the action of dense phase static pressure difference, a large number of cavities mixed in the material plug will lead to the disintegration of the material plug, which will affect the stability of the entire dense phase transportation, so there are certain defects
