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

1. Introduction

The unloader is used to install in the negative pressure work of the unloader discharge port, the upper part of the acceptance of the unloader discharged materials, relying on the rotating impeller plays a role in conveying materials, but also assume the role of sealing, to prevent the pneumatic conveying process from the discharge port inhalation of air, the unloader's normal discharge as a special unloading equipment, in the cleaning and cleaning work plays a great role. So we need to summarize some of its characteristics, so you can better do a comprehensive understanding of the unloader and maintenance, play its ability.

(1) The unloader is often used in the pneumatic output system, for the pressure output system or negative pressure output system, the unloader can be uniform, continuous material supply to the delivery pipe. To pneumatic output pipe gas, solid is relatively stable, so that the pneumatic conveying can work normally, at the same time, but also will be able to unloader on the lower part of the air pressure isolation and play a role in locking gas. Therefore, the unloader is an important part commonly used in pneumatic conveying system.

(2) Then the material of the upper silo falls by its own weight and fills in the gap between the blades, it is discharged in the lower part with the rotation of the blades. Therefore, the discharger can quantitatively and continuously discharge materials.

(3) The unloader can be used in the collection of materials in the system, as the unloader of the silo. The unloader is currently the domestic into the unloading device, often used in the dust removal system as one of the important equipment in the dust removal system. It is especially suitable for dust, small particles of material, by the environmental protection, metallurgy, chemical industry, food, cement, road construction, drying equipment and other industrial projects in the industry of choice.

(4) Temperature-resistant type, the temperature of the material it conveys can reach 280°C. The bearings at both ends are isolated from the impeller, which can prevent the ultra-fine powder from contacting with the bearings. High-temperature type unloader conveys materials at temperatures up to 500°C and adopts chain wheel connection. There is a certain distance between the reducer and the unloader shell.

2. 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.
