Boiler accessory machining treatment method

Abstract

The invention provides a boiler accessory machining treatment method. Auxiliary treatment equipment is used in the method. The auxiliary treatment equipment comprises a bottom plate, a fixing plate, clamping mechanisms, an operation frame, polishing mechanisms, and locking mechanisms. The operation frame is mounted on the bottom plate; the polishing mechanisms are mounted on the operation frame; the locking mechanisms are symmetrically mounted on the left and right sides of the upper end of the operation frame; the fixing plate is mounted on the locking mechanisms; and the clamping mechanismsare mounted inside the fixing plate. According to the boiler accessory machining treatment method, large-batch precision polishing treatment can be conducted while the ventilation aperture of a boilerhood is completed, so that tedious operation of one-piece polishing is completely avoided, the pass rate of products is increased, and meanwhile the productivity can be greatly improved.

Description

technical field [0001] The invention relates to the field of boiler fitting processing, and specifically proposes a processing method for boiler fittings. Background technique [0002] The boiler air cap is the air distribution device of the boiler and one of the important accessories of the boiler. The small air cap apertures are evenly arranged on the boiler air cap, which plays a key role in the safe and economical operation of the boiler. The working principle of the boiler air cap is blown out by the air cap. The wind blows up the coal or combustibles to form a boiling combustion. When the wind cap is used again, there are usually hundreds of them, and they are arranged at intervals at the bottom of the furnace. Its application range is usually power station boiler burner nozzles, machinery, mines, Metallurgy, chemical industry, military industry, transportation, cement production equipment, etc. [0003] Existing boiler hoods are generally processed by casting. The ve...

AI Technical Summary

Problems solved by technology

[0003] Existing boiler hoods are generally processed by casting. The ventilation holes on the boiler hood are very small, so the ventilation holes are often blocked after casting, which is very dangerous when used. However, the ventilation holes are usually processed by Manually use iron rods with the same hole diameter to grind, and the efficiency of grinding the boiler hood one by one is low, the process is cumbersome, and affects production efficiency, so there is still room for improvement
