Boiler Blast Machines

Boiler blast machines are used for preparing the insides of water heaters for subsequent enamelling (wet or powder enamelling).

Depending on the handling system we offer semi-automatic and fully-automatic systems:

Without a transportation system water heaters are loaded/unloaded manually. According to the desired throughput 1, 2 or 3 boilers are processed at the same time. The shown machine features 3 combined blasting and cleaning stations:

In most cases this equipment is used in combination with a P+F conveyor system, occasionally also with a circular conveyor. According to specifications either 1, 2 or 4 boilers are processed simultaneously. The shown machine features 4 ea. blasting and cleaning (= air purging & rapping) stations and is loaded by a Power+Free conveyor:

Positioning of boilers is done pairwise by means of suspension frames:

After positioning blast nozzles and air purging nozzles resp. move from below into the boilers. In the cleaning station boilers are additionally rapped pneumatically:

By default boilers are rotated during the blasting process. Optionally the lances can be rotated, e.g. if boiler rotation is not possible due to lateral extensions of the water heaters. Lance rotation alsois needed with so-called twin boilers.
