Pneumatic stirring and mixing device

Abstract

The invention discloses a pneumatic stirring and mixing device, which belongs to the technical field of stirring and mixing equipment. A convex waist-shaped cylindrical mixing inner cavity is formed in the device, compressed air is sprayed out through air spray heads which are connected with the tail ends of the two air conveying pipes and are tangent to the inner wall of the mixing inner cavity;two jet heads are opposite in direction, therefore, a medium in the mixing inner cavity is driven to rotate in a vortex shape; the tail ends of a first gas conveying pipe and a second gas conveying pipe are fixedly connected to a mounting disc; the mounting disc and the two gas conveying pipes can be driven to rotate clockwise for a certain angle by clockwise rotating and meshing the sector gear above the mounting disc; an air spraying head on the air conveying pipe moves to different liquid level heights to drive all media to rotate; and when the sector gear below rotates and is in contact engagement with the gear, the mounting disc and the two gas conveying pipes can be driven to rotate anticlockwise and circulate in a reciprocating manner, so that the gas conveying pipes and the gas spraying heads swing up and down periodically to stir a medium, the manufacturing cost and the energy consumption are reduced, and meanwhile, the expected stirring effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of stirring and mixing equipment, and in particular relates to a pneumatic stirring and mixing device. Background technique [0002] Pneumatic mixers are mainly used in petroleum, chemical, paint, paint, ink, resin, medical, food, daily chemical and other flammable and explosive, dust, heavy load, cosmetics, flavors and fragrances, shoe factories, leather factories, wood products factories, Handicrafts, papermaking, adhesives, tire manufacturing, water treatment and other places. [0003] At present, many solution stirring devices use electric devices, such as submersible mixers, paddle mixers or underwater flowmakers, but these devices need to be connected to electricity, and they are all electric. The stirring blades are driven by the electric drive motor to stir the liquid. , the rotary electric agitator can only make the solution produce a single vortex flow state in the center of the solution tank, and...
