This kind of tunnel kiln crown structure, its characteristic in: the kiln crown structure is divided and is formed by kiln crown girder steel part, hanging part branch, heat retaining unit. Kiln crown heat retaining unit divides by being provided with diamond dust, heat resisting steel card slot, fire -resistant insulation material in to outward. The utility model provides a telescopic tunnel kiln crown structure, sealed effectual, the heat is difficult to run off, can freely stretch out and draw back along with the change of temperature, can not receive heat preservation refractory material's deformation and suffers the damage, has also simple structure simultaneously, construction convenience's advantage.
Description
Technical field
The utility model belongs to building field, and particularly one has telescopic tunnel cave roof construction.
Background technology
Tunnel cave is the Thermal Equipment that modern continous way is burnt till, and is widely used in the baked for producing of the products such as refractory material.Tunnel cave is a long linear tunnel, and fixing wall and vault are arranged at its both sides and top, and the track that bottom is laid runs kiln car.Calcination equipment is located at the both sides, middle part of tunnel cave, constitute fixing high temperate zone---clinkering zone, the high-temperature flue gas that burning produces is under the effect of the front end induced-draft fan of tunnel cave, flow along tunnel cave to kiln hood direction, the goods in kiln are immersed in preheating step by step simultaneously, and this band constitutes the preheating zone of tunnel cave.Blast cold wind at the kiln tail of tunnel cave, the goods of latter a section in cooling tunnel kiln, the cold wind blasted flows through goods and after being heated, then extracts out and send into the thermal source of drier as dried, and this section constitutes the salband of tunnel cave.
The most frequently used in the material on current flat suspending ceiling tunnel kiln top is do skeleton with shaped steel (or beams of concrete material), forms with light-weight refractory fragment of brick, prefabricated heat resistance concrete boatswain chair assembling (or heat resistance concrete is cast-in-place).Wherein mostly flat furred ceiling refractory brick blocks is the material compositions such as magnesia, aluminium silicon, calcium, belongs to crystal complex, and long term high temperature process crystal formation changes, volume contraction.Simultaneously fragment of brick is heated and can expands, and produces very large thermal stress, causes cracking of building body, crowded bad; Variations in temperature is fast in addition, local contraction non-homogeneous expansion is even, dilatation joint that must be reasonable in design during construction, if gap is too small, easily there is partial collapse in later stage kiln top, if gap is excessive, easily causes the loss of heat, and bring irreversible pyrolytic damage to steel body mechanism, reduce the service life on kiln top.And other refractory material to there is sealing effectiveness equally bad, the shortcoming that heat easily runs off.
Iron sheet used at present as hanging the device of flame-proof thermal insulation material, shortcoming be subject to refractory material variations in temperature and there is easy distortion, easily cracking, easily squeeze bad, and heat insulating ability is bad, and structure is tight not.
Utility model content
For the deficiencies in the prior art, the utility model provides one to have telescopic tunnel cave roof construction, and this structure can bear high temperature action for a long time, has not yielding, not easy to crack, not easily crowded bad, and good heat preservation performance, the advantage that air-tightness is good.
The technical scheme realizing the utility model object is:
One has telescopic Novel tunnel furnace roof construction, comprise kiln top girder steel part, hanging part and insulating sections, kiln top girder steel part crossbearer is on Yao Qiang, and kiln top girder steel part is connected with insulating sections by hanging part, and insulating sections is suspended in below kiln top.
Kiln top girder steel part is made up of shaped steel, as the force structure on kiln top, power is passed to the supporting constructions such as kiln wall.
Hanging portion subpackage enclosing wire rope and elevator, steel wire rope top connects kiln top girder steel part, and bottom connects kiln top insulating sections by elevator, and the gravity of kiln top insulating sections is evenly passed to kiln top girder steel part.
Insulating sections comprises left heat resisting steel board slot, middle heat resisting steel board slot, right heat resisting steel board slot, the husky groove of the first appearance, the second appearance husky groove, diamond dust and flame-proof thermal insulation material, left heat resisting steel board slot and right heat resisting steel board slot are fixed on the kiln wall of both sides, middle heat resisting steel board slot is connected with left heat resisting steel board slot and right heat resisting steel board slot respectively, contacts and does not carry out hinged.Be reserved with the husky groove of the first appearance between left heat resisting steel board slot and middle heat resisting steel board slot, right heat resisting steel board slot and middle heat resisting steel board slot are reserved with the husky groove of the second appearance.First holds husky groove, and second holds the diamond dust be filled with a sealing in husky groove, and flame-proof thermal insulation material is connected to below left heat resisting steel board slot, middle heat resisting steel board slot and right heat resisting steel board slot by steel wire rope, forms a kind of sealing kiln roof construction that can stretch along with temperature.
Beneficial effect
The utility model provides one to have telescopic tunnel cave roof construction, the distortion that this structure solves existing flat suspending ceiling tunnel kiln kiln top temperature change and causes, poor air-tightness, the technical problem that heat easily runs off, the flat suspending ceiling tunnel kiln that the variations in temperature and causing being specially adapted to bear high temperature and low temperature is expanded with heat and contract with cold, and it is lightweight to meet tunnel cave top, vertebration and the characteristic of good heat preservation performance, compared with current kiln roof construction, telescopic tunnel cave roof construction provided by the utility model, good sealing effect, heat not easily runs off, can along with the change free-extension of temperature, the distortion of heat insulating refractory material can not be subject to and be damaged, have also that structure is simple simultaneously, the advantage of easy construction.
