Mainly used for the furnace front limestone powder feeding system of circulating fluidized bed boilers in thermal power plants. It uniformly feeds limestone powder from the limestone silo, and also has metering and frequency conversion functions to adjust the feeding amount of limestone.
Purpose of Pneumatic Unloading Valve:
Mainly used for the furnace front limestone powder feeding system of circulating fluidized bed boilers in thermal power plants. It uniformly feeds limestone powder from the limestone silo, and also has metering and frequency conversion functions to adjust the feeding amount of limestone. This product adopts an airtight seal for shaft sealing, which ensures good sealing performance, easy operation and maintenance, and reliable operation.
Working principle and characteristics of pneumatic unloading valve:
This product is driven by an electric motor through a reducer to rotate a rotor with blades inside the housing. The material falls from the upper ash hopper to between the blades and is discharged from the lower end along with the blades, achieving uniform and smooth feeding of the material.
The feature of this product is that it adopts an airtight sealing form at the shaft. During operation, the pressure inside the sealing chamber is always greater than the pressure inside the material chamber, thus ensuring a tight seal at the shaft; The reducer adopts a helical gear hard tooth surface reducer, which has a more compact, reasonable structure, smaller volume, and higher transmission efficiency and load-bearing capacity. It can also be installed horizontally, making the entire product structure more compact and smaller in size. The blade adopts an adjustable structural form, which allows the gap between the blade and the shell to be adjusted (the gap is not greater than 0.15mm). At the same time, due to the low blade speed and good wear resistance, the service life of the valve is extended.
