Embodiment Construction

[0011] Such as figure 1 According to different working conditions, the gas with appropriate temperature and pressure is selected from the outside through the vent pipe (1), passes through the one-way vent valve (3), and enters the set distributed air holes and drive on the hollow stirring blade (4). Vent discharge, distribution The gas discharged from the vent directly acts on the liquid to distribute and stir, and the vent gas is driven to generate a rotational driving force. When the gas pushes the stirring blade (4) to rotate, the ejected gas is evenly distributed in the liquid , the rotating stirring paddles (4) push the liquid to stir to play the role of mechanical stirring, making full use of the positive and negative kinetic energy of the air pressure, which can effectively save energy.

Abstract

The invention relates to a mixing stirrer with a paddle with airflow driven by air pressure, which is structurally distinguished from other stirrers. Gas is blown from the outside by an air inlet pipe welded on a kettle body, enters a hollow stirring paddle connected to the air inlet pipe by a one-way valve and finally, is discharged by air holes on a paddle. The gas can act on fluid directly; and moreover, reverse thrust can be generated to drive the stirrer to work so as to achieve double stirring (the structural drawing is shown in the accompanying drawing of the abstract of a specification). The mixing stirrer with the paddle with the gas driven by the air pressure is designed aiming at the energy consumption, the production cost and the stirring effect in the stirring process. The mixing stirrer with the paddle with the airflow driven by the air pressure has the characteristics of making up some defects of other stirrers, simplifying the structure of equipment and lowering the manufacturing cost, so that the installation of the stirrer is diversified. The occurrence of leakage and pollution when the reactions of oxidation, hydrogenation and the like are carried out in the processes of petrochemical engineering, organic synthesis and food processing can be better avoided.

Description

Technical field: [0001] Stirring has been widely used in petrochemical, biological, food, pharmaceutical and other industries. It consists of paddles, stirring shafts, driving devices and sealing devices. Stirring has two or more media forms such as liquid-liquid, liquid-solid, gas-liquid, etc. The purpose of stirring is to dissolve, disperse, ferment, crystallize, react, etc. the stirring liquid. At present, the mixing equipment in our country is developing rapidly, various new high-efficiency agitators emerge in endlessly, and new agitators and mixing methods are widely used. Background technique: [0002] Mechanical stirring is a mechanical device that uses the stirring shaft to drive the rotation of the paddle to input mechanical energy to the fluid in the kettle. The widely used six-blade disc turbine and other agitators can effectively complete all stirring operations. Its advantage is that it has a large shear force, which can make the fluid micro-groups dispersed v...
