Described urceolus is provided with air inlet and the air outlet that connects, and wherein cold air is discharged from air outlet and made combustion air supply shaft furnace from the space preheating of air inlet entering intraformational bed and outside sandwich.
The outer wall of described burner hearth lower flange place, stainless steel inner core also is provided with a semi arch loop expansion pipe, and the two ends of telescopic joint are fixing with lower flange and the welding of stainless steel inner core respectively, and the top of telescopic joint is provided with heat-insulation layer.
Advantage of the utility model and beneficial effect:
1, the utility model adopts crashproof formula design, and the heavy wall heat-resistance stainless steel is made inwall, and improve service life greatly, and can not pollute aluminium water because of peeling off of refractory material.
2, be welded with heat conduction muscle sheet on the utility model inwall stainless steel; Whole body of heater is divided into intraformational bed, outside sandwich, heat-insulation layer, and the advanced internal layer of the cold air of high pressure positive blower arrives outer again, can take heat out of; Make combustion air and participate in burning; Effectively utilize this part heat energy, according to Theoretical Calculation, but 100 ℃ of effective energy-saving of the every raising of combustion air are more than 5%.
3, the utility model shaft furnace lower flange is designed with semicircle arcuation telescopic joint, can effectively solve the problem of thermal deformation, and increases heat-insulation layer, makes the commissure keep stationary temperature; Improve the service life of body of heater so greatly, make design more reasonable.
