Abstract
The utility model discloses a channel push plate kiln furnace for extraction and production of ZrO. The channel push plate kiln furnace for the extraction and production of ZrO comprises a channel kiln furnace body; the channel kiln furnace body adopts a metal steel plate as a shell and is sequentially provided with an inner layer, a middle later and an outer layer from inside to outside; the inner layer is of a Al2O3 hollow brick layer; the middle layer is a mullite polycrystalline fiber layer; the outer layer is a calcium silicate board; multiple movable push plates arrayed straightly are arranged in the furnace body; a push-in section, a preheating section, a heating section, a heat preservation section, a cooling section and an output section are sequentially arranged in the furnace body from front to back; the push-in section is provided with a pusher and the output section is provided with a push-out machine. The channel push plate kiln furnace for the extraction and production of ZrO can bear higher sintering temperature, and a thermal insulation layer is light in weight and less in heat adsorption, so the energy consumption of the kiln furnace is reduced; the furnace body adopts the pusher, the movable push plates and the push-out machine to form a conveying mechanism, so the continuous drying and sintering for the ZrO are realized.
Description
Technical field
The utility model relates to a kind of tunnel like ejection plate kiln of producing for zirconium white extraction, belongs to zirconium white extraction and produces purification techniques field.
Background technology
Pure zirconium white is a kind of crystal of white, there is high rigidity, high strength, high tenacity, the physical and chemical performance that high wear resistance and chemical resistance etc. are good, obtains application widely in pottery, refractory materials, machinery, electronics, optics, opticfiber communication, clock and watch ornaments, aerospace, biology, chemistry etc. various fields.But the zirconium white in reality often contains a certain amount of iron contamination, color is grey or faint yellow, the zirconium white performance generation considerable change that contains impurity, has limited the application of pure zirconia at high-temperature field, also needs the zirconium white to containing iron contamination to carry out purification by liquid extraction in practice.
In ripe zirconium white extracting production process, having an operation is will heat and dry cake processed containing the zirconia solid of certain moisture, at present, this operation mainly will complete in tunnel like ejection plate kiln, just refer now to, the structure of the tunnel like ejection plate kiln of producing for zirconium white extraction in industry is generally such: body of heater innermost layer refractory brick is the poly-light brick of corundum-mullite, then be from inside to outside followed successively by the poly-light brick of mullite, high alumina gathers light brick, alumina silicate fiber felt, but because temperature in the tunnel like ejection plate kiln of producing for zirconium white extraction is higher, body of heater internal layer is that near the temperature of Si-Mo rod is higher near resistance heating element, in actual use, the kiln body of heater radiation temperature that often meeting can not be born Si-Mo rod due to internal layer corundum-mullite, in use for some time, just start the kiln that collapses, in addition, because thermofin is that alumina silicate fiber felt density is high, weight is large, heat absorption is many, cause the energy consumption of the tunnel like ejection plate kiln of producing for zirconium white extraction high, energy dissipation is large.
Utility model content
The purpose of this utility model is to provide a kind of tunnel like ejection plate kiln of producing for zirconium white extraction, the radiation temperature that can not bear Si-Mo rod to overcome the kiln of prior art, thermofin density is high, weight large, heat absorption is many, energy consumption is high, the defect that energy dissipation is large.
To achieve these goals, the technical solution of the utility model is:
A kind of tunnel like ejection plate kiln of producing for zirconium white extraction, comprise tunnel-kiln type body of heater, this body of heater adopts metal foil to make shell, in shell, be disposed with from inside to outside internal layer, middle layer and skin, described internal layer is aluminum oxide hollow brick layer, described middle layer is mullite polycrystalline fibre layer, and described skin is Calucium Silicate powder flaggy; In described body of heater, be provided with a plurality of portable push pedals that are rods arranged in horizontal line, described body of heater is followed successively by the section of pushing, preheating section, heating zone, holding-zone, cooling section and deferent segment from front to back, the section of pushing arranges pusher, deferent segment arranges kickoff mechanism, so design, can realize zirconic continuous drying sintering.
As the improvement to technique scheme, described body of heater is arranged with support.
The beneficial effects of the utility model are: the tunnel like ejection plate kiln body of heater internal layer of producing for zirconium white extraction of the present utility model is more heat-resisting aluminum oxide hollow brick layer, middle layer is that heat-insulating property is better, weight is lighter, the less mullite polycrystalline fibre layer of heat absorption, compared to the prior art, the tunnel like ejection plate kiln of producing for zirconium white extraction of the present utility model can bear higher firing temperature, thermofin is lightweight, heat absorption is few, thereby reduces kiln energy consumption; Body of heater adopts pusher, portable push pedal, kickoff mechanism to form transfer mechanism, can realize zirconic continuous drying sintering.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the layer structure enlarged diagram of body of heater of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.
As illustrated in fig. 1 and 2, the tunnel like ejection plate kiln of producing for zirconium white extraction of the present utility model, comprise tunnel-kiln type body of heater, this body of heater adopts metal foil to make shell 11,11 li, shell is disposed with internal layer 8, middle layer 10 and outer 9 from inside to outside, described internal layer 8 is aluminum oxide hollow brick layer, and described middle layer 10 is mullite polycrystalline fibre layer, and described outer 9 is Calucium Silicate powder flaggy; In described body of heater, be provided with a plurality of portable push pedals that are rods arranged in horizontal line, described body of heater is followed successively by the section of pushing 2, preheating section 3, heating zone 4, holding-zone 5, cooling section 6 and deferent segment 7 from front to back, and the section of pushing 2 arranges pusher 1, and deferent segment 7 arranges kickoff mechanism 12.
Described body of heater is arranged with support 13.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
