The structure of one-piece tunnel kiln.

Between a heat tunnel kiln is mainly composed of feeding mechanism, driving mechanism, rotary tube axial support device, heat-resistant metal rotary kiln body, front and rear wheel, heating, before and after stent, percussion device, heating element, cooling device, exhaust, discharging mouth, kiln body Angle adjusting mechanism, electrical control system, etc.

The one-piece tunnel kiln, the rotary tube is made up of heating tube and cooling pipe flange and got behind key block one, two paragraphs by cooling pipe length is 1/2-3/5 of the heating tube, commonly thickness is about 1/3-1/2 of heating tube, heating tube is made of 1 cr25ni20si, cooling pipe material is 1 cr18ni9ti. One-piece structure tunnel kiln due to heating tube and cooling pipe couplet body, so the structure is compact, only need a retarding mechanism drive, its manufacturing and operation cost are low, and the whole area is small, that is the main advantage of it.
