Abstract
The invention discloses an electric kiln, which comprises a kiln body, a kiln hearth and a kiln hearth port, wherein a kiln door is arranged on the kiln body positioned on one side of the kiln hearth port; the kiln wall of each side of the kiln body has a structure consisting of outer, middle and inner layers; each outer layer is a metal shell; each middle layer is a heat-insulating layer; each inner layer is a heating layer. The electric kiln has the characteristics of convenience, high flexibility, high mobility, easiness and convenience in operation, low pollution and low cost, and is suitable for the field of firing of corundum aeration heads.
Description
?
Technical field
The present invention relates to aeration head and fire processing technique field, refer in particular to a kind of electrical kiln.
Background technology
Pushed bat kiln, claims again pusher furnace or push-plate type tunnel cave, is a kind of continous way heat-agglomerating equipment, according to the technological requirement of sintered products, arranges required warm area and power, and thermal technology's part of component devices, meets the demand of product to heat.Sintered products is directly or indirectly placed in the push pedal of high temperature resistant, wear-resisting wiping, is moved being placed on product in push pedal according to the technological requirement of product by propulsion system, in burner hearth, complete the sintering process of product.
Pushed bat kiln belongs to minitunnel kiln one class, utilizes coal heating flame to be called coal-burning pushed bat kiln in designed combustion chamber, pushed bat kiln both sides; Along with the enhancing of environmental consciousness, utilize the pushed bat kiln of coal-fired heating to change steam stove into many, use natural gas or coal gas to carry out combustion heating.It is higher that combustion of natural gas need to be equipped with special natural gas combustion nozzle cost, and be often subject to the restriction of source of the gas supply, be many mainly with gas-fired greatly, be generally equipped with the burning of Mini producer gas generator supply stove, pushed bat kiln is generally equipped with two to six of coal gas burners and splits pushed bat kiln both sides or a side.
Tunnel cave is generally a long linear tunnel, and fixing wall and vault are arranged at its both sides and top, on the track that lay bottom, is moving kiln car.Combustion apparatus is located at the both sides, middle part of tunnel cave, form fixing high temperate zone--clinkering zone, the high-temperature flue gas that burning produces is under the effect of tunnel cave front end chimney or air-introduced machine, flow along tunnel to kiln hood direction, preheating enters the goods in kiln step by step simultaneously, and this section formed the preheating zone of tunnel cave.Kiln tail at tunnel cave blasts cold wind, the goods of latter a section in cooling tunnel kiln, and flow through goods and after heated of the cold wind blasting, then extract out and send into the thermal source of drier as dried, this section just formed the salband of tunnel cave.
The heating flame of tunnel cave is mainly heavy oil, light diesel fuel, and natural gas and coal gas, original direct combustion coal mode is not multiplex.Oils burning is equipped with oil storage tank and burner noz(zle).Because of the higher use of oils cost more be still natural gas and coal gas, natural gas is to have special natural gas combustion nozzle to carry out spray combustion natural gas transport to kiln by natural gas line.Gas-fired is except having single-minded gas pipeline transportation service to stove, tunnel cave user mostly carries out the production of coal gas from having gas generator, the coal gas being produced by gas generator is delivered to tunnel cave combustion chamber through piping, carries out spray combustion by coal gas burner.
In sum, prior art exists problem and shortcoming:
1, pushed bat kiln, tunnel cave adopt coal gas or combustion of natural gas, cause production cost higher, and waste resource is larger, seriously polluted, not environmental protection.
2, existing pushed bat kiln, tunnel cave adopt coal gas or combustion of natural gas, and its shortcoming is that the temperature difference is large, easily encircles kiln, causes homogeneity of product poor (having ripe), workman's manipulation strength large (operation continuously).
3, the manufacturing cost of pushed bat kiln, tunnel cave self is also large.
Summary of the invention
The present invention for the problem that solves prior art and exist provide a kind of convenience, flexible property strong, easy and simple to handle, pollute little, cost is low fires the electrical kiln that aeration head is used.
For solving above technical problem, a kind of electrical kiln of the present invention, comprises kiln body, kiln thorax and kiln thorax mouth, and the kiln body that is positioned at kiln thorax mouth one side is provided with wicket; That the kiln wall of described each side of kiln body all has is outer, in, interior three-decker, skin is metal shell, middle level is insulating, internal layer is zone of heating.
Further improve, it is that 3mm adds the iron plate of brushing antiseptic and rustproof paint that described metal shell adopts thickness.
Further improve, it is 80mm alumina bubble brick that described insulating adopts thickness.
Further improve again, in described zone of heating, be provided with heating wire.
Compared with prior art, beneficial effect of the present invention:
1, flexible property is strong, and fecund to be burnt, and few product is few to be burnt.
2, automatically control, easy to operate.
3, zone of heating adopts heating wire, and temperature is even, good product consistency, and quality is guaranteed.
4, pollute littlely, the feature of environmental protection is good, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of kiln wall of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, 2, a kind of electrical kiln of the present invention, comprises kiln body 1, kiln thorax 2 and kiln thorax mouth 3, and the kiln body 1 that is positioned at kiln thorax mouth 3 one sides is provided with wicket 4; That the kiln wall 5 of described kiln body 1 each side all has is outer, in, interior three-decker, skin is metal shell 6, middle level is insulating 7, internal layer is zone of heating 8.
It is that 3mm adds the iron plate of brushing antiseptic and rustproof paint that metal shell 6 described above adopts thickness; It is 80mm alumina bubble brick that insulating 7 adopts thickness; In zone of heating 8, be provided with heating wire 9.
Above-mentioned is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improvement and adjustment also should be considered as protection scope of the present invention.
