Ash Discharge Valve

Manual insert valve is also called spiral gate valve, it is to control the discharge of materials. Often supporting electric feeder, rotary ash unloading valve and other use, mainly to facilitate the electric feeder, star unloader maintenance can be controlled when the material is closed in the silo does not leak out, it is compact, simple operation, long service life, not prone to failure.

Ash Discharge Valve Working Principle

Star unloader, also known as electric ash unloading valve, rotary ash discharge valve, impeller discharge valve, rotary feeder, etc. This product is mainly the main equipment for bag filter conveying, ash discharge and other equipment unloading, suitable for powder materials, granular materials, widely used for environmental protection, mining, metallurgy, chemical industry, food, chemical and other industrial sectors.
Unloader is divided into three categories: common type, pressure resistant type and high temperature resistant type. Unloaders can be driven at a uniform speed to discharge materials continuously according to the controlled rate, or driven at a variable speed to use the unloader as a feeder.
Product features.
(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 the structure is compact, beautiful and novel, small volume and light weight.
(2) The unloader runs reliably and smoothly, with low noise, low failure and long life, and the gear housing parts are made of ductile iron and bearing steel. Good performance and high wear resistance.
(3) The bearing, gear box, away from the valve body, to avoid the influence of high temperature dust, good sealing performance of the front and rear end cover, to prevent dust leakage, prolong the service life of the transmission parts, lubrication system.
(4) The unloader has strong overload capacity, impact resistance, small inertia torque, suitable for frequent start/stop and forward/reverse rotation.
(5) Users need special specifications, motor, sprocket drive and other unloaders, can be made. According to the user needs to configure special special motor, such as explosion-proof, frequency control, speed control, marine motor, etc., to meet the special requirements of users. 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, etc.

Ash Discharge Valve Applications

Ash discharge valves are used in industrial applications to control the flow of ash or other abrasive materials from hoppers, bins, or silos. Here are some common applications of ash discharge valves:

• Coal-fired power plants: In coal-fired power plants, ash discharge valves are used to control the flow of ash from the bottom of the furnace or boiler. This prevents ash buildup and helps maintain efficient operation of the plant.
• Cement plants: Ash discharge valves are used in cement plants to control the flow of cement kiln dust (CKD) from the kiln. CKD is a byproduct of the cement-making process and can be used as a supplementary cementitious material in concrete.
• Waste incineration: Ash discharge valves are used in waste incineration plants to control the flow of ash from the incinerator. This helps prevent ash buildup and ensures that the plant operates efficiently.
• Steel mills: Ash discharge valves are used in steel mills to control the flow of slag from the furnace. Slag is a byproduct of the steel-making process and can be used as a construction material.
• Chemical plants: Ash discharge valves are used in chemical plants to control the flow of abrasive materials such as catalysts, minerals, and powders. This helps prevent blockages and ensures that the plant operates smoothly.
