Rotational fluidized bed powder mixing machine

Abstract

The invention discloses a rotational fluidized bed powder mixing machine which comprises a material mixing cabin body, a material inlet, a material outlet, a bag type dust collector and a sampling hole, wherein a static mixer is mounted inside the material mixing cabin body; rotational flow nozzles are mounted at the bottom of the material mixing cabin body; and the rotational flow nozzles are connected with an air flow distributor. When the machine is used, continuous air flow is fed into the material mixing cabin body through the rotational flow nozzles, then a rotational fluidized bed layeris formed, granular materials are driven to turn over up and down, powder granular materials can be relatively intensely mixed in the lifting and dropping process through the static mixer inside thematerial mixing cabin body, and a very good mixing effect is achieved within a short time. The rotational fluidized bed powder mixing machine is relatively simple in structural mode and simple and convenient to operate and maintain, and the mixing quality of different batches of powder granular materials can be ensured with relatively low air consumption within a relatively short mixing time.

Description

Technical field: [0001] The invention relates to a powder particle material mixing device, in particular to a rotary fluidized bed powder mixing device. Background technique: [0002] For different batches of powder particles, mechanical stirring or fluid drive can be used, so that two or more powder particles can be uniformly distributed in each position, thus ensuring the high quality of the product. Because there are no parts that need to be rotated inside the airflow powder mixing equipment, compared with the commonly used mechanical stirring powder mixing equipment, it has a series of advantages of less complicated structure and relatively less maintenance and repair. At the same time, because the airflow is used to drive the powder for mixing, there are no stirring parts like stirring paddles, which avoids the wear and tear of mechanical powder mixing equipment due to the high-speed rotation of the paddles and the possible coating peeling off of the paddles due to high...

Problems solved by technology

Although airflow mixing equipment can make up for some shortcomings of mechanical mixing equipment, compared with mechanical mixing equipment, the current research and analysis on airflow mixing equipment is far less detailed than mechanical mixing equipment, and its structure is far less than mechanical mixing equipment. The structure of the equipment is diverse, and these problems need to be solved in order to obtain an airflow powder mixing equipment with a higher mixing effect
