A device for forced convection and uniform mixing of liquid and gas media. The type, size and speed of mixer have influence on the distribution of mixing power between the whole activity and turbulence fluctuation. Generally speaking, the power distribution of Turbo mixer is beneficial to turbulence fluctuation, while the propeller mixer is beneficial to overall activity. For the same type of mixer, under the condition of the same power consumption, for the mixer with large diameter and low rotation speed, the power is mainly consumed in the overall activity, which is conducive to the macro mixing. For the mixer with small diameter and high rotating speed, the power is mainly consumed in turbulence fluctuation, which is beneficial to micro mixing. The expansion of the mixer is a complex problem related to the process. Up to now, it can only be expanded by experience. According to the obtained expansion criteria, it can be extrapolated to the industrial scale.
Mixer is used for mixing equipment. It is usually used to mix materials. In order to improve the use efficiency of the equipment, what should be paid attention to when placing materials?
1. It should be careful when adding materials. It should try to avoid heating materials in empty tanks or cold materials in hot tanks. Too large temperature difference impact has some impact on the function of enamel. Together, it should be ensured that hard solid objects will not be transferred into the kettle. As for large hard materials that do not need to participate, they should be added after damage.
2. During operation, it should be noted that when the temperature of the equipment is raised through the jacket, it is necessary to slowly increase the pressure and temperature. The pressure of 0.1mp shall be applied in advance, and after a quarter of an hour, the steam shall be applied slowly to reach the operating pressure.
3. During operation, pay attention to the sealing conditions of mixer flange, adapter plate, manhole and stuffing box, and take measures in case of leakage.
4. When discharging, it should be noted that if the mixer is blocked, it can not be shoveled with metal tools, but can be quietly poked open with bamboo or plastic rods or wood rods. When the response is over and the cooling is required, the cold water should be put into the jacket after the temperature naturally drops to some extent.
Therefore, when the mixer is discharging, it is necessary to pay attention to observe the use of the machine, add materials according to the condition, and check the accessories.
