氣流攪拌是利用氣體鼓泡通過液 體層，對液體產生攪拌作用，或使氣泡群一密集狀態上升借所謂上升 作用促進液體產生對流循環。與機械攪拌相比，僅氣泡的作用對液體 進行的攪拌時比較弱的，對于幾千毫帕·秒以上的高粘度液體是難于 使用的。但氣流攪拌無運動部件，所以在處理腐蝕性液體，高溫高壓 條件下的反應液體的攪拌時比較便利的。
Gas stirring is the use of gas bubbles through the liquid layer, to produce stirring effect on the liquid, or make the bubble group a dense state rise, by the so-called rising effect to promote the liquid convection circulation. Compared with mechanical stirring, the effect of bubbles on liquid stirring is weaker, and it is difficult to use for high viscosity liquid with several thousand MPa · s. However, there are no moving parts in the air flow stirring, so it is more convenient to deal with corrosive liquid and reaction liquid under high temperature and high pressure.
In industrial production, mixing operation starts from the chemical industry, and is widely used as a part of the process around food, fiber, paper, oil, water treatment, etc. Mixing operation is divided into mechanical mixing and air mixing.
Do not use welding tools on branches with holes as this will damage the lining. Electric welding (gas welding) tools shall not be used for perforating branch pipe of mixer, because electric welding will damage the plastic lining of mixer, and the connection of branch pipe must be beveled with special pipe fittings; electric welding (gas welding) tools shall not be used for perforating branch pipe of mixer, because electric welding will damage the plastic lining of mixer, and the connection of branch pipe must be beveled with special pipe fittings.
In order to control the rotation of the mixing cylinder, we must pay attention to putting a wedge between the supporting wheel and the raceway; turn off the engine, remove a high-pressure oil pipe of the hydraulic motor, and the mixing cylinder can rotate freely. Control the rotation of the mixing cylinder to make the maintenance hole turn to the lower part, and then open the maintenance hole to clean up the commercial concrete in the cylinder. At this time, it must be noted that after the discharge of product concrete, the commercial concrete cement mixer truck shall be restored to its original state.
