Electric feeder

Overview of electric feeder:

Electric feeder is also called feeder, star-shaped unloader, suitable for dry powder or fine granular non-sticky dry materials. Such as raw meal powder cement, dry slag coal powder, fly ash and so on. It is used for air-locking and uniform feeding when conveying dry powdery and granular materials. It can feed the conveying pipe uniformly and continuously. In the separation and dust collection section of the system, it can also be used as a unloader. It is installed in the lower part of the ash hopper or ash warehouse such as the electric precipitator, economizer, air preheater and so on. This product can work continuously below 200 ℃, with novel structure, good sealing and convenient maintenance.

Introduction Electric feeder is also called star-shaped ash valve, star-shaped unloader, rotary unloader. It consists of valve body, transmission shaft, vane and reducer. The reduction motor drives the drive shaft and impeller to rotate, so as to achieve the purpose of ash unloading. It has the characteristics of good blade abrasion resistance, high air-locking performance, complete discharging, stable connection and compact structure. The electric feeder uses elastic rotors, which has better sealing performance and ensures uniform feeding. The electric feeder is used to continuously and uniformly feed dry powdery materials or small granular materials in the upper silo to the next equipment. It is a kind of quantitative feeding equipment.
Scope of use: The scope of use of the electric feeder: The electric feeder is the main equipment for dust removal, air supply and other equipment feeding. The electric feeder is suitable for powdery materials and granular materials. Widely used in environmental protection, metallurgy, chemical, food, food and other industrial sectors.
Advantages (1) By adopting the principle of planetary rotation, the input and output shafts are on the same axis, and have the uniqueness of being directly integrated with the motor, so the structure is compact, beautiful, novel, small in size and light in weight.
(2) Superior sealing performance, uniform and stable feeding, stable unloading operation, low noise, few failures, long service life and high wear resistance.
(3) Bearings, gearboxes, away from the valve body, to avoid the influence of high temperature dust, the front and rear end covers have good sealing performance, prevent dust from leaking out, and prolong the service life of motor parts and lubrication systems.
(4) Strong overload capacity, low impact inertia force, suitable for frequent starting and reverse rotation.
(5) According to the user's needs, special special motors, such as explosion-proof, frequency-adjusting, speed-adjusting, marine motors, etc., are provided to meet the user's special requirements. Material can also be processed according to user needs, such as high temperature resistance, corrosion resistance, stainless steel, flexible blades, explosion-proof impellers, etc.
