Installation form of mixing devices
Mixing equipment can be classified from a variety of different angles, such as the process uses points, points or points according to the mixing device installation type agitator structure type, etc.. Points, from the stirring device mounting type can be divided into the center of vertical container (1) mixing (2) eccentric mixing (3) mixing the end of the tilting mixing (4) (5) horizontal container and mixing (6) next- mixing six, and next into the mixing which can be divided into a fixed angle of the next into the mixing and the mixing angle variable of the next-in two.
Selection of vertical container center mixing design. This mixing device is installed in the center line of the vertical cylinder device, the drive to belt drive and gear drive, with normal motor directly connected or directly connected with the reducer.
Operation of the mill, blender drive grinding ball movement, which crushed material particles to reach the grinding effect.
Mixing equipment has a long history and wide application, but not enough scientific research on the mixing operation. The mixing operation may seem simple, but in reality is extremely complex, involving factors. Blender choice of the form, from a process point of view as well as the mechanical point of view, so far studied enough.
The past, a lot of literature on the power consumption of the mixing device, and gives the formula for calculating the number of cases, but due to differences in media operating conditions of different physical and chemical properties of the container shape and internal facilities different as well as a variety of stirrer the nature of the difference, it is very difficult to correctly determine the appropriate mixing power and select the drive motor. The method is often used in the simulations, the design of new mixing equipment, existing equipment data, rather, not to small, resulting in a lot of waste. Some units of the domestic production of mixing equipment, power can be seen from the results of the test, the power consumption is difficult to calculate accurately, motor selection is too large, resulting in very low loading rate unreasonable phenomenon.
Mixing equipment, in addition to the power problems, the mixing of the fluid mechanics research is important. This has done a lot of work, but should be expanded and in-depth. To stir the liquid, the stirrer function of not only cause of the whole movement of the liquid, but also closely related to the turbulence, the degree of turbulence and the stirrer so that the liquid spinning vortex phenomenon in liquid. These vortices are often hit each other and break down, so that the liquid under intense stirring. Can be seen in the mixing operation for the study of fluid mechanics theory is extremely important.
The various existing blender to blender, unless in case of a special task that requires special design, especially the commonly used type of box, flat paddle,coal preparation equipment propulsion and turbine has enough applications. And corresponding standard these agitator has a deep understanding of the existing agitator performance should be more attention to in order to enable them to be able to fully play a role in use. Turbine agitator is widely used, because this blender is a great industrial adaptability, almost all mixing tasks,coal mining equipment and often encountered in particular the chemical industry kinds of viscosity of the material.
