Abstract
The utility model relates to a kind of type waste sludge incinerator kiln hood structure, it is characterized in that: this kiln hood structure is made up of kiln hood backplate and kiln cylinder body, kiln cylinder body internal circumference has groove, kiln hood backplate is provided with convex key, convex key and groove cooperatively interact, leave space between convex key and bottom portion of groove, described kiln cylinder body and kiln hood backplate are bolted.It is more reasonable that the utility model has structure, processing more for convenience, production cost is lower, and be easier to the advantages such as maintenance, kiln hood backplate and the Embedded structure of kiln cylinder body, make refractory material in cylinder not fragile, kiln hood backplate not easily deforms, thus extends the service life of refractory material, backplate and kiln cylinder body.
Description
Technical field
The utility model relates to a kind of kiln hood structure, and especially a kind of type waste sludge incinerator kiln hood structure, is mainly applicable to the harmless treatment of municipal sludge.
Background technology
Incinerating kiln kiln hood domestic is at present all the structural design adopting cement equipment rotary kiln, kiln hood is made up of cold wind shroud and kiln hood backplate, due to cold wind shroud complex structure, manufacturing cost is high, and operationally to be equipped with cooling blower, operation and maintenance cost is higher, and the simultaneously distortion of cold wind shroud, play have also badly influenced normal production.Between kiln hood backplate and kiln cylinder body, general mode only with bolts is carried out in addition, and at high temperature backplate bolt easily deforms and makes Joint failure, causes refractory material in cylinder drop and hot spot occurs, kiln body gross distortion.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides the type waste sludge incinerator kiln hood structure that a kind of reasonable in design, production cost are lower, processing technology is simpler, be easier to maintenance.
The utility model takes technical scheme as follows: a kind of type waste sludge incinerator kiln hood structure, be made up of kiln hood backplate and kiln cylinder body, kiln cylinder body internal circumference has groove, kiln hood backplate is provided with convex key, convex key and groove cooperatively interact, leave space between convex key and bottom portion of groove, described kiln cylinder body and kiln hood backplate are bolted.Because convex key set on kiln hood backplate is embedded in kiln cylinder body internal circumference, at high temperature the occurred thermal expansion stress of the refractory material of inner barrel is born by convex key and recessinterengaging means, prevent simple bolt connecting mode to lose efficacy because high temperature deformation causes connecting, and then make the refractory damage of inner barrel.Therefore effectively extend the service life of refractory material and kiln hood backplate in kiln cylinder body, it also avoid the damage to kiln cylinder body simultaneously.
As preferably, groove the right and left of described kiln cylinder body is symmetrically arranged with multiple screw.Be connected with kiln hood backplate by bolt at screw place, make whole kiln hood structure comparatively firmly and be easy to dismounting and maintenance.
As preferably, described kiln cylinder body adopts high temperature resistant steel plate to make.Kiln cylinder body is at high temperature not easily deformed.
The utility model compared with prior art, there is structure more reasonable, processing more for convenience, production cost is lower, and be easier to the advantages such as maintenance, kiln hood backplate and the Embedded structure of kiln cylinder body, make kiln hood backplate not easily deform, thus extend the service life of refractory material in kiln hood backplate, kiln cylinder body and kiln cylinder body.
Accompanying drawing explanation
Fig. 1 is the profile of kiln hood structure in the utility model embodiment.
Fig. 2 is the profile of the partial enlargement at A place in Fig. 1.
Fig. 3 be in the utility model embodiment kiln cylinder body groove by the expanded view of cylinder internal diameter.
In figure: 1-kiln hood backplate, 2-kiln cylinder body, the convex key of 3-, 4-groove, 5-screw, 6-bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail.
See Fig. 1 to Fig. 3, the present embodiment is made up of kiln hood backplate 1 and kiln cylinder body 2, kiln hood backplate 1 is provided with convex key 3, kiln cylinder body 2 internal circumference has the groove 4 matched with convex key 3, convex key 3 is embedded in groove 4, space is left between bottom convex key 3 and groove 4, what the Axial Thermal stress making kiln hood backplate 1 at high temperature occurred coordinated by convex key 3 and groove 4 bears, the connected mode because of simple bolt 6 is avoided Joint failure to occur when high temperature, effectively extend the service life of refractory material in kiln hood backplate 1 and kiln cylinder body 2, it also avoid simultaneously to kiln cylinder body 2 damage.
Groove 4 the right and left of kiln cylinder body 2 is symmetrically arranged with screw 5, and left and right respectively has two, to play the connection function to kiln cylinder body 2 and kiln hood backplate 1.Kiln cylinder body 2 is connected by bolt 6 at screw 5 place with kiln hood backplate 1, makes detachable maintaining convenient; Kiln cylinder body 2 adopts high temperature resistant steel plate to make, and kiln cylinder body 2 is at high temperature not easily deformed.
By foregoing description, those skilled in the art can implement.
Above embodiment has made comparatively detailed description to the utility model, but these descriptions are not to restriction of the present utility model, and namely the utility model is not limited to concrete structure and the description of above-described embodiment.All according to the equivalence done of structure, shape and feature described in the utility model design or simple change, be included in the protection domain of the utility model patent.
