Design Rotary Airlock Valve Cement Grain Star Unloader Ash Coal Mine Rigid Impeller Feeder

1. Introduction

Star unloader is also known as star unloading valve, electric lock valve, star unloader, rotary feeder, lock valve, usually the structure of the star unloader is composed of a rotor impeller with several blades, shell, seals, and reducer, motor, etc. According to the conditions of the work will be divided into three categories of ordinary, pressure-resistant, high-temperature-resistant, commonly used in the pneumatic output system, for the pressure output system or negative pressure output system, the star unloader can be evenly and continuously to the feeding tube to ensure that the gas and solids in the pneumatic output tube is more stable, so that the pneumatic conveying can work properly. For the pressure output system or negative pressure output system, the star unloader can supply materials to the feeding tube evenly and continuously to ensure that the gas and solids in the pneumatic output tube are relatively stable, so that the pneumatic conveying can work normally, and at the same time, it can isolate the upper and lower air pressure of the unloader and play a role in locking the air. Therefore, star unloader is an important part commonly used in pneumatic conveying system.

The unloading device is divided into three parts, motor, cycloid reducer and the rotary ash unloading valve.
(1) By adopting the principle of planetary rotation, the input and output shafts are on the same axis, and there is the uniqueness of being directly connected with the motor, thus the structure is compact, the modeling is beautiful and novel, the volume is small and the weight is light.
(2) Excellent sealing performance, uniform and stable feeding, smooth discharging, low noise, less failure, long service life, high wear resistance.
(3) Bearings, gear box, away from the valve body, to avoid the influence of high temperature dust, before and after the end cover sealing performance is good, to prevent dust leakage, to extend the service life of the motorized parts, lubrication system.
(4) Strong overload capacity, impact resistance and small inertia force, suitable for frequent starting and inverse rotation.
(5) According to the user needs to configure special special motors, such as explosion-proof, frequency control, speed control, marine motors, etc., in order to meet the user's special requirements. In the material can also be according to user needs for special processing, such as high temperature resistance, corrosion resistance, stainless steel, flexible blade, explosion-proof impeller.
