A kind of air pressure type solution mixer

Abstract

The present invention relates to a pneumatic solution agitator, comprising a reciprocating piston assembly and a mixing barrel, the mixing barrel is provided with an air guide chamber, a stirring chamber and an air pressure chamber; the reciprocating piston assembly includes a reciprocating assembly and a piston mechanism, the piston The gas in the mechanism shrinks and expands under the drive of the reciprocating component. The piston mechanism includes an exhaust port that doubles as the suction port. The exhaust port communicates with the air guide chamber; It is a semi-closed cavity, the opening end of the mixing chamber communicates with the air guide chamber through a one-way valve A, and the conduction direction of the one-way valve A is from the stirring chamber to the air guide chamber; the opening end of the air pressure chamber passes through the one-way valve B communicates with the air guide chamber, and the conduction direction of the one-way valve B is from the air guide chamber to the air pressure chamber; the outer wall of the mixing chamber and the inner wall of the air pressure chamber are connected through a number of release holes; the whole stirring mechanism is fully sealed, Compared with the shaft-type driving mechanism, the pressure-bearing performance is better, and the piston size is increased to reduce noise.

Description

Technical field [0001] The invention relates to an air pressure solution stirrer, belonging to the field of pharmaceutical stirring equipment. Background technique [0002] Traditional pharmaceutical mixing equipment generally uses a mechanically driven mixing stick or mixing impeller to stir and mix the pharmaceutical industry. This mechanical equipment has a relatively primitive structure and has the following problems: [0003] 1. The dead angle of the equipment is relatively large, and some granular materials may accumulate in the corner of the equipment and cannot be fully stirred; [0004] 2. Because of the limited pressure-bearing performance of the joint of the rotating mechanism, this type of equipment cannot be suitable for some working conditions that require mixing under special pressure and gas environment; [0005] 3. Generally, stirring rods and stirring blades are driven by electric motors or diesel engines, and the equipment is noisy and vibrates; [0006] 4. The stirr...
