Working Principle and Characteristics of the Unloader

 1. The working principle of the unloader

 

Unloaders are divided into three categories: ordinary type, pressure-resistant type, and high-temperature type. The unloader can be driven at a uniform speed to continuously discharge materials at a controlled rate, or driven at an indefinite speed, using the unloader as a feeder.

 

(1) Common type of unloader:

 

It can be used for normal materials below 150 degrees and normal temperature, and it can continuously and evenly feed the material into the conveying pipe. In the system and the separation dust collection part, it can also function as a unloader.

 

(2)Pressure-resistant unloader:

 

It uses a closed rotor, which can be widely used in suction and pressure-feed air conveying systems and negative pressure conveying equipment. The rotating unloader can ensure that the air pressure in the conveying pipe does not leak and can safely convey and collect materials, and it can withstand pressure and also has those functions of ordinary ones.

 

The characteristics of the unloader

 

(1) The unloader adopts the principle of planetary rotation, the input and output are on the same axis, and it has the uniqueness of being directly connected with the motor, so it has a compact structure, beautiful appearance, small size, and light weight.

 

(2) The unloader is reliable and stable in operation, low in noise, low in failure, and long in life. The teeth are made of ductile iron and bearing steel. Moreover, it has good performance and high wear resistance.

 

(3) Bearings, gear boxes, keep away from the valve body, avoid the influence of high temperature and dust, the front and rear covers have good sealing performance, prevent dust from leaking, and extend the service life of motor parts and lubrication systems.

 

(4) The unloader has strong overload capacity and small impact resistance moment of inertia, which is suitable for frequent starting and reverse rotation.

 

(5) If users need special specifications, unloaders such as motors and sprocket drives can be manufactured.
