In Production of Ceramics, a large amount of tunnel caves that use are fired, the sintering temperature of tunnel cave is between 950 ℃-1050 ℃, therefore the insulation construction of tunnel cave is not only related to thermal loss, the consume fuel of tunnel cave, also can affect the normal operation of kiln and operate artificial safety, thering are great economical, societal benefits.Existing tunnel furnace heat-insulation layer comprises ceiling board, fire brick layer, rock wool layer and pearl rock stratum, and while keeping 1,000 temperature after testing in kiln body, outer surface still has the temperature of 70-90 ℃, and not only heat insulation effect is poor, also has certain potential safety hazard.
For addressing the above problem, Granted publication number discloses a kind of tunnel furnace heat-insulation layer for CN202133267U, comprise ceiling board, fire brick layer, rock wool layer and pearl rock stratum, it is characterized in that, also comprise the broken quarrel layer of alumina silicate fibre layer and aerated-block, described ceiling board, fire brick layer, alumina silicate fibre layer, rock wool layer, the broken quarrel layer of aerated-block and the once order laminating from bottom to top of pearl rock stratum.In addition, application publication number is that CN103743433A discloses movable heat-preservation type tunnel kiln, comprise tunnel cave body, its feature in: the described furnace wall that will carry is provided with composite plate, this composite plate is fixed by lining and the inside panel and the outer wall that separate form, composite plate surrounding evenly seals, and forms cavity, and inside panel is fixed with refractory insulating layer by tunnel cave body inboard.Above-mentioned two kinds of tunnel cave insulation constructions all have certain effect, but more than stove chamber inner combustion to 1200 ℃ during high temperature heat insulation effect undesirable, the temperature of hearth outer wall is high, need further improvement.
Utility model content
For overcoming deficiency of the prior art, the utility model provides a kind of good seal performance, the stable thermal-insulating type tunnel kiln of kiln car.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of thermal-insulating type tunnel kiln, comprise kiln main body and Yao Ding, its feature in: described kiln main body comprises kiln skeleton and burner hearth insulation construction, this kiln skeleton and kiln push up combined formation burner hearth, and this burner hearth insulation construction comprises thermal insulation board, asbestos mat, high temperature mullite, intermediate layer, floating bead brick, intermediate layer, high temperature polycrystalline fibre and the iron plate of outwards being arranged successively by inboard wall of burner hearth.
Further, intermediate layer comprises thermal insulation board and the asbestos mat of outwards being arranged successively by inboard wall of burner hearth.
Further, kiln top is provided with kiln top heat preservation mechanism.
Further, kiln top heat preservation mechanism, includes iron sheet, asbestos mat and light fire brick from outside to inside successively.
Further, also comprise waste-heat recovery device, described kiln main body comprises preheating section, high temperature section, quench zone, cooling section, and this waste-heat recovery device is arranged at kiln top above and is communicated with preheating section, quench zone, cooling section respectively.
From above-mentioned to description of the present utility model, compared with prior art, the thermal-insulating type tunnel kiln that the utility model provides, simple in structure, easy construction, low cost of manufacture, adopted the kiln body of unique texture and insulation construction to improve burner hearth heat insulation effect, after testing, during kiln stove chamber inner combustion to 1400 ℃, the temperature of the outer surface of kiln main body only has 30-35 ℃, can reduce heat and run off, saved the energy, improve the security performance of kiln.
