Abstract
The utility model discloses a rotary kiln kiln wall structure, including inboard electrical heating layer, the metal casing in the outside, electrical heating layer central authorities set up the electric heating furnace pole, set up the blast air electric fan between electrical heating layer and the metal casing, the inboard of metal casing sets up the flame retardant coating. Set up the screen cloth between electrical heating layer and the blast air electric fan, the screen cloth is stainless wire net, and the flame retardant coating is the refractory ceramic layer. The thickness of flame retardant coating is 8cm at least. The flame retardant coating lays the inboard at the metal casing. The utility model discloses not only can can also increase the outer surface texture's of rotary kiln stability so that the inside heat of rotary kiln scatters more uniformly, the difficult casing that takes place is out of shape.
Description
Technical field
The utility model relates to a kind of novel rotary kiln wall construction, more particularly, relates to a kind of rotary kiln wall construction.
Background technology
Rotary kiln compares common manufacturing and processing equipment in molybdic acid goods, and its work characteristics is exactly that warm-up time is long, temperature height, and the requirement of continuous operation is higher. Traditional rotary kiln does not have external reinforcement structure, under long-time high bake, the high temperature deformation of housing extremely easily occurs, once housing has gap that the control to in-furnace temperature will be caused uneven, affects the judgement to reaction in furnace. And my company is in order to address this problem, first corresponding filtering net is set between the blast fan and heating layer of the even wind in inside, secondly lay a certain amount of refractory layer in the inner side of metal housing.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant, through repeatedly putting into practice improvement, devises a kind of rotary kiln wall construction, not only can so that the heat of rotary kiln inside more evenly scatters, the stable of rotary kiln outer surface structure can also be increased, housing distortion not easily occurs.
Technical scheme: in order to realize foregoing invention object, the technical scheme that the utility model adopts is: a kind of rotary kiln wall construction, comprise the electric heating layer of inner side, the metal housing in outside, described electric heating layer central authorities arrange electrical heater bar, arranging air blast electric fan between described electric heating layer and metal housing, the inner side of described metal housing arranges flame retardant coating. Arranging screen cloth between described electric heating layer and air blast electric fan, described screen cloth is Stainless Steel Cloth, and flame retardant coating is refractory layer.
Further, the thickness of described flame retardant coating is at least 8cm.
Again further, described flame retardant coating is laid in the inner side of metal housing.
Useful effect: compared with prior art, its useful effect is the utility model:
The utility model not only can so that the heat of rotary kiln inside more evenly scatters, moreover it is possible to increase the stable of rotary kiln outer surface structure, housing distortion not easily occurs.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of rotary kiln wall construction of the utility model.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of rotary kiln wall construction, comprises the electric heating layer 1 of inner side, the metal housing 6 in outside, and described electric heating layer 1 central authorities arrange electrical heater bar 2, arranging air blast electric fan 4 between described electric heating layer 1 and metal housing 6, the inner side of described metal housing 6 arranges flame retardant coating 5. Arranging screen cloth 3 between described electric heating layer 1 and air blast electric fan 4, described screen cloth 3 is Stainless Steel Cloth, and flame retardant coating 5 is refractory layer.
The thickness of described flame retardant coating 5 is at least 8cm.
Described flame retardant coating 5 is laid in the inner side of metal housing 6.
The above is only preferred implementation of the present utility model; it is noted that, for those skilled in the art; under the prerequisite not departing from the utility model principle; can also making some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
