Rigid impeller feeder is used in the chemical industry due to the physical and chemical properties of its materials, so we need to pay attention to the precautions when selecting it:
1. Working environment
That is, how it works, or what environment it works in and what role it plays in the environment.
For example, its purpose at work is to unload materials evenly or in the environment, in addition to evenly discharging materials, it also has the important task of locking air.
2. Physical and chemical properties of the material
That is, whether the material is harmful to the equipment, that is, whether the material is corrosive and whether the material is abrasive to the equipment.
Chemical feeders use a relatively tightly sealed rotor, which is widely used in suction-type and pressure-type air flow conveying systems and negative pressure conveying equipment. It can ensure that the air flow pressure in the conveying pipe does not leak. Able to transport and collect materials safely, chemical rigid impeller feeders are generally used to transport some sticky, high-temperature and corrosive materials.
Because the advantage of stainless steel is corrosion resistance, it is not easy for materials to deteriorate and be corroded. Stainless steel is very smooth, not easy to stick, has high corrosion resistance and high density, so the sealing performance is better than that of ordinary unloaders. , the impeller is elastic, and it is relatively simple and convenient in cleaning dust. It has a wide range of uses. It can ensure that the air flow pressure in the conveying pipe does not leak, and can safely convey and collect straw materials and some toxic powdery materials.
