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。在工業生產中，攪拌操作時從化學工業開始的，圍繞食品、纖維、造紙、石油、水處理等，作為工 藝過程的一部分而被廣泛應用。攪拌操作分為機械攪拌與氣流攪拌。
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 special pipe fittings must be used for groove connection of branch pipe; 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 special pipe fittings must be used for groove connection of branch pipe.
In order to control the rotation of the mixing drum, a wedge should be placed between the roller and the raceway; Turn off the engine and loosen a high-pressure oil pipe of the hydraulic motor. The mixing drum can rotate freely. Control the rotation of the mixing drum to turn the maintenance hole to the lower part. Then open the maintenance hole and clean up the commercial concrete in the drum. 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.
