(1) Heating is a common phenomenon during the mixing process of heating or cooling materials.
1. The mixing process of some materials can be realized in a certain temperature environment, in order to meet the blendability of the material, and the mixing uniformity can be improved.
2. Some of the mixture materials themselves contain a certain amount of water. In the mixing process, the water can be dried by a simple method such as increasing the temperature to achieve a simple mixing and drying function.
For the mechanical powder mixing equipment, the heating or cooling of the mixing vessel shell ensures that the mixing vessel is at a constant temperature during the mixing process, which is the main method for the mixer to keep warm, and the traditional name is the jacket.
According to different temperature requirements, the common heating methods are: 1 heat transfer oil is added to the jacket, the heating wire is directly heated by the heat transfer oil, 2 circulating oil is heated, 3 steam circulation is heated, in order to improve the energy utilization efficiency, the heating jacket needs to be further heated. The layer is insulated to prevent heat from escaping into the air. In order to meet the heating requirements of the mixing process, the equipment generally requires an auxiliary boiler or other energy equipment. In order to eliminate steam or other emissions from heating during mixing, the system also needs to be equipped with a set of air intake and dust removal systems.
(2) If the vacuum or pressurized material may be oxidized during the mixing process or other processes that cannot be completed in the air state, it is necessary to evacuate the mixing equipment container, and if necessary, to be filled with inert gas protection, etc. .
For example, in the mixing process of the explosive, it is necessary to completely remove the oxygen element in the mixing container, and then fill the container with argon gas or other inert gas to prevent the heat from being generated by the friction during the mixing process.
(3) In order to satisfy the mixing of a small amount of liquid in the powder mixing process, and to increase the mixing uniformity of the liquid and the powder, it is necessary to contact the powder with the powder in an atomized state.
For example, when we mix the gray surface, if the water and the gray surface are co-loaded into the container and then mechanically mixed, it is difficult to mix evenly; if the water is mechanically moved, the water is in contact with the gray surface in a mist, and the mixture is evenly mixed. Degrees and mixing time will be greatly improved.
(4) If there are fibers or other difficult-to-disperse materials in the fly-boiler equipment mixture, high-speed dispersion is required during the mixing process, and the mixing equipment needs to design and manufacture a high-speed rotating flying knife shaft.
Second, the choice of auxiliary equipment Mixer is the core of the mixing process. In order to improve the mixing speed and the automated process of mixing, the mixer also needs to be equipped with other auxiliary equipment to meet the mixing process as a whole. The working mode of the conventional mechanical mixing equipment is the gap operation. The materials of the single batch need to be prepared first → add the mixer → evenly mix → discharge (1) the feeding equipment is needed to increase the time of the gap mixing operation. Each prepared mixture is quickly added to the mixer. In order to prepare the materials that need to be mixed each time, manual ingredients or automatic ingredients can be designed.
(2) Discharge equipment Mixing machine discharge According to different forms, different processes have different ways. But no matter what form, the mixed materials need to be placed in the silo or other next-step process equipment.
