In order to solve the problems of the technologies described above by the following technical solutions: a kind of high temp sintering resistance furnace, comprise the burner hearth with heat-insulation layer, lower furnace portion is provided with kiln furnitures by base support in the burner hearth, be provided with the whirligig of hot air circulating system in the stove and carrying workpiece in burner hearth.
Hot air circulating system comprises the gas channel that is comprised of inboard wall of burner hearth and furnace lining in the described stove, and the high-temperature heating resistance wire is housed in the gas channel; Furnace lining and both sides, burner hearth bottom intersection are provided with air inlet, and the furnace lining top is provided with air outlet; Heat-resisting circulating fan also is installed in the roof of the furnace lateral surface by motor support frame, and the output shaft of heat-resisting circulating fan passes roof of the furnace and enters in the burner hearth and with fan blade and be connected, and fan blade is positioned at above the air outlet.
Furnace lining employing sintered silicon carbon sheet material or high temperature resistant cast steel, heat-resistance stainless steel sheet material.
Heat-resisting circulating fan adopts water or wind to force cooling.
The whirligig of described carrying workpiece comprises the electric rotating machine that is fixed on the burner hearth bottom outside by fixed support; The output shaft of electric rotating machine passes burner hearth bottom and furnace lining, and the output shaft upper end is connected with the rotary support base; The rotary support base is arranged in the furnace lining, and kiln furnitures are arranged on the rotary support base.
The utility model has guaranteed that well high temperature burns till the uniformity of different parts temperature in the resistance furnace, after particularly loading large batch of workpiece, by forced convertion and kiln furnitures rotation, eliminated the hot working effect deviation in traditional kiln, while is effectively regulated and improves the interior firing atmosphere of stove, has improved the quality of burning till of workpiece; Temperature homogeneity is good, can take full advantage of furnace volume, increases substantially the output of single stove, has reduced the energy resource consumption of single products, has very high economic benefit and practical value.
Description of drawings
Fig. 1 is the structural representation that high temperature burns till chamber type electric resistance furnace in the background technology.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, a kind of high temp sintering resistance furnace comprises the burner hearth 3 with heat-insulation layer, and burner hearth 3 bottoms are supported by base 7, is provided with the whirligig of hot air circulating system and carrying workpiece in the stove in burner hearth 3.
Hot air circulating system comprises the gas channel 9 that is comprised of inboard wall of burner hearth 15 and furnace lining 16 in the stove, and high-temperature heating resistance wire 2 is housed in the gas channel 9; Furnace lining 16 is provided with air inlet 19 with both sides, intersection, burner hearth 3 bottom, and furnace lining 16 tops are provided with air outlet 8; Heat-resisting circulating fan 10 also is installed in the roof of the furnace lateral surface by motor support frame 11, and heat-resisting circulating fan 10 adopts water or wind to force cooling; The output shaft of heat-resisting circulating fan 10 passes roof of the furnace and enters in the burner hearth and is connected with fan blade 12, and fan blade 12 is positioned at above the air outlet 8, and fan blade 12 makes the inner generation of burner hearth air flow.
