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。
Air flow stirring is to use the gas bubble to stir the liquid through the liquid layer, or make the bubble group rise in a dense state, and promote the convective circulation of the liquid through the so-called rising effect. Compared with mechanical stirring, the stirring of liquid only by the action of bubbles is relatively weak, and it is difficult to use high viscosity liquid more than thousands of MPA · s. However, air flow stirring has no moving parts, so it is more convenient to deal with corrosive liquid and stirring of reaction liquid under high temperature and high pressure. In industrial production, the mixing operation starts from the chemical industry and is widely used as a part of the process, focusing on food, fiber, papermaking, petroleum, water treatment, etc. The mixing operation is divided into mechanical mixing and air flow mixing.
Do not use welding tools on perforated branches, as this will damage the lining. Electric welding (gas welding) tools shall not be used for the perforated branch pipe of the mixer, because electric welding will damage the plastic lining of the mixer, and the branch pipe must be connected with special pipe fittings; Electric welding (gas welding) tools shall not be used for the perforated branch pipe of the mixer, because electric welding will damage the plastic lining of the mixer, and the branch pipe must be connected with special pipe fittings.
Put a wooden wedge between the supporting wheel and the raceway to control the rotation of the mixing drum. Be sure to pay attention to it; Turn off the engine, remove a high-pressure oil pipe of the hydraulic motor, the mixing drum can rotate freely, control the rotation of the mixing drum, turn the maintenance hole to the lower part, and then open the maintenance hole to clean out the commercial concrete in the drum. At this time, it must be noted that after the product concrete is discharged, the commercial concrete cement mixer truck shall be restored to its original state.
