Description
Technical Field
The patent relates to a stifled central batcher is prevented to adjustable speed high efficiency.
Background
The raw coal bunker is an important component of a coal-fired power plant boiler pulverizing system, the cross section of the raw coal bunker is circular or square, the longitudinal section of the raw coal bunker is conical or hyperbolic, and the raw coal bunker has a large upper opening and a small lower opening. The raw coal particles flow downward by their own weight. The raw coal at the lower part needs to bear the weight of the raw coal piled at the upper part, and the cross section of the bin body is gradually reduced along the flowing direction, so that the raw coal at the lower part of the bin body is more compact, and the fluidity is greatly reduced. Particularly, when raw coal is wet or is mixed with fuels with higher viscosity such as biomass, coal slime and the like, the materials are easy to generate the phenomena of wall adhesion, arch lapping, caking and the like, and block a feeding passage to cause coal breakage, thereby seriously influencing the safe and stable operation of the boiler.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art, and providing a speed-adjustable high-efficiency anti-blocking central feeder.
A speed-adjustable efficient anti-blocking central feeder comprises a storage bin, a chassis and a speed reducer; a conical cavity is arranged in the bin, the cross section of the conical cavity is gradually reduced from top to bottom, a guide cone is further arranged at the center of the bin, and the cross section of the guide cone is gradually increased from top to bottom; the outer wall of the chassis is provided with a gear ring, the upper part of the chassis is sleeved with an outlet at the bottom of the storage bin, the lower part of the chassis is connected with the blanking pipe through a thrust bearing, the central axes of the thrust bearing and the blanking pipe are coincident, a plurality of pairs of scraping arms are fixed on the chassis, and the scraping arms are positioned on the side wall between the chassis and the flow guide cone; the output end of the speed reducer is meshed with the gear ring on the outer wall of the chassis through a gear set, and the input end of the speed reducer is connected with the motor.
Preferably, the bin, the lower bearing ring of the thrust bearing, the speed reducer and the motor are all connected with the outer support frame.
Preferably, the diversion cone is connected with the storage bin through an inner supporting arm and a maintenance channel.
Preferably, the diversion cone coincides with the central axis of the storage bin.
