In order to eliminate the swirling phenomenon of the liquid in the stirred vessel and make the stirred liquid churn up and down to achieve uniform mixing, it is usually necessary to add a baffle in the stirred vessel. Generally, the width of the baffle is about 1 / 12 ~ 1 / 10 of the inner diameter of the vessel, and the accessories in the equipment, such as thermometer, heat transfer coil or various supports, can also play a role of baffle, but often can not reach the "full baffle condition". Generally, the power consumption will increase with the increase of baffle width, but when it reaches a certain value, the power consumption will not increase again. The working condition at this time is called "full baffle condition".
In the concrete mixing tank, the fluid can flow to the mixer in all directions, and the length of the fluid stroke is different. When it is necessary to control the speed and direction of the return flow, the guide tube can be used to determine a first-class condition. The draft tube is a cylinder with upper and lower openings, which is installed in the container and plays a guiding role in mixing. It can not only improve the mixing degree of the fluid in the container, strengthen the direct shear effect of the agitator on the fluid, but also create a certain circulation flow, so that the fluid in the container can pass through the strong mixing area in the draft tube and improve the mixing efficiency. After installing the draft tube, the circulation path is limited and the chance of fluid short circuit is reduced. The draft tube is mainly used for the diversion of propelling, screw and turbine agitators.
The function of the transmission device is to make the mixing shaft rotate at the required speed and ensure the mixing shaft to obtain the required torque. In most mixing equipment, there is only one mixing shaft, and the agitator rotates in one direction at a constant speed. However, there are also some special mixing equipment, in order to obtain better mixing effect, two mixing shafts can be used in one mixing equipment, and the complex movement of the mixer can be carried out, such as reciprocating, reciprocating, planetary and so on.
Let's talk about the procedure. When unloading, you should keep an eye on it. Don't try to save trouble and let it go. Many discharging unions operate the discharging lever while the driver is away. Besides, they can keep an eye on it to ensure normal operation without causing damage to the tank, reducer and supporting wheel. Keep a good relationship with the stocklayer, foreman and workers around. After all, acquaintances are easy to handle affairs. Don't forget to ask the person in charge to sign when you leave at last. This is very important. If you don't sign, it means that you have done nothing.
