Technology and specification:①Sprocket for cast steel material, the casting surface roughness should be selected according to the requirements of GB 6060.1, after casting it must be clean and trim flash, burr, remove poured riser, adhering sand, scale and inner cavity residue, etc,Poured riser cutting residual quantity should comply with the rules；②Tempering heat treatment, the first step, and tempering hardness HB260 ~ 320；The second step for chain nest quenching, quenching hardness HRc45 ~ 55, quenching hardness layer depth of no less than 3 mm.Sprocket manufacture should comply with GB/T 24503-2009；③After manufacturing it shall be the completion of the chain and sprocket meshing experiment, ensure both completely mesh, the chain can not have clip,jump the whole assembly is completed, check whether the chain wheel and drive shaft rotation is flexible, rust removing, polishing processing inspection qualified products, ensure the surface finish, paint layer surface without tumor when painting.
System Composition of the Bottom Ash Conveyor:
The dry slag conveying system is made up of boiler bottom slag discharge device, steel band conveyor, crushing and conveying device, slag storage hopper, slag unloading device for slag silo, hydraulic system, and electric and control system.
Steel band conveyor is the kay equipment of the dry slag conveying system, installing at the outlet of the boiler bottom slag discharge device. The conveyor is made up of steel band, chain scraper (cleaning chain), and the casing. The steel band consists of high temperature resistant conveying belt, supporting roller, under roller, side limit roller, driving mechanism, and tension mechanism. The scraper cleaning chain consists of chain, scraper, under roller, driving mechanism, and tension mechanism. There are one adjustable air inlet at both side of the casing, and two air inlet holes at the top of the casing, which can adjust the air according to the generated slag quantity. There are one access doors at both ends of the conveyor used for short time maintenance of the steel band and cleaning chain. The hydraulic tension mode is used for the conveyor belt and the chain scraper, the pressure supply is shared with the hydraulic crusher, and the accumulator tank is available. The function of the steel band conveyor is to continuously receive and sent out high temperature boiler bottom ash, and make the ash have further burning and cooling during the conveying. The conveying speed can be adjusted in accordance with the bottom ash quantity.
