The unloader consists of a shell, an impeller and a driving device. Its working principle is that the motor reducer drives the impeller to rotate uniformly to achieve the purpose of uniform feeding. After being energized, the impeller rotates in the casing, leaving a space between the casing and the impeller. If the impeller collides with the casing, then the empty space, too small gap will cause the impeller to rotate at a constant speed. If the gap is too large, the material will leak out when it is not rotating, and the material will enter the gap between the shell and the impeller, and then the shaft rotates to generate wind pressure, which blows the main shaft to both ends along the material, forming at both ends of the bearing Material running.

The main reasons for unloader leakage are as follows:

1. The gap between the walls of the impeller discharger is too large, and the material is easy to leak during the unloading process. Therefore, a rubber pad can be placed on the impeller to solve the problem of material leakage. The discharger wall will always discharge against the housing. Wear and tear constitutes leakage.

2. The unloader is a very important part of the ash discharge process of various dust removal equipment. It ensures the effect of sealed warehouse and continuous or continuous ash discharge. Obviously, the soot column of the corresponding height is stored in the ash hopper of the high-negative electrostatic precipitator. Good sealing effect. The machine has a series of advantages such as compact structure, beautiful appearance, convenient use, stable operation and low noise.

3. Since the unloader bearing and gearbox are separated from the housing by a certain distance, the conventional unloader has been greatly improved in terms of high temperature resistance and smoothness. The structure of the star unloader is usually rare. It consists of a rotor impeller with blades, a shell, a seal, a reducer and an electric motor.

When the material in the upper silo falls due to its own weight and fills the space between the blades, the material will be discharged from the upper part as the blades rotate. This is how the unloader works. The uninstall program can be uninstalled continuously. The operation is simple, and the produced star unloader has a long service life.
