气流搅拌是利用气体鼓泡通过液体层，对液体产生搅拌作用，或使气泡群一密集状态上升借所谓上升 作用促进液体产生对流循环。与机械搅拌相比，仅气泡的作用对液体 进行的搅拌时比较弱的，对于几千毫帕·秒以上的高粘度液体是难于 使用的。但气流搅拌无运动部件，所以在处理腐蚀性液体，高温高压 条件下的反应液体的搅拌时比较便利的。在工业生产中，搅拌操作时从化学工业开始的，围绕食品、纤维、造纸、石油、水处理等，作为工 艺过程的一部分而被广泛应用。搅拌操作分为机械搅拌与气流搅拌。
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.
