Preferably, be filled with pebbles between said ground and the said hot application slag case.
Can find out from technique scheme; Outer wall and concrete partition that the utility model embodiment provides the connection of hot application slag case system to support all with hot application slag case pass through bolt; Cause the phenomenon that weld seam bursts with regard to having avoided because saturation steam bulging force and chemical reaction produce the effect of huge bulging force like this, thereby prolonged the life-span of hot application slag case system effectively.
Description of drawings
The structural representation of the hot application slag case system that Fig. 1 is provided for the utility model embodiment.
Embodiment
The purpose of the utility model provides a kind of hot application slag case system, to prolong the life-span of hot application slag case system.
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, all other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belong to the protection domain of the utility model.
Please refer to Fig. 1, the structural representation of the hot application slag case system that Fig. 1 is provided for the utility model embodiment.
The hot application slag case system that the utility model provides comprises the hot application slag case 1 that connects support 2, concrete partition 4 and be positioned over ground; Wherein hot application slag case 1 normally is welded by heat-resisting steel sheet and plate; Can certainly adopt other material, can under hot environment, work as long as guarantee hot application slag case 1; Connect to support 2 and all pass through bolt with the outer wall and the concrete partition 4 of hot application slag case 1.Since adopt in the hot application slag case system that provided of the utility model embodiment bolt connect respectively with hot application slag case 1 with is connected support 2 be connected support 2 and concrete partition 4 is fixed; Therefore this causes the phenomenon that weld seam bursts with regard to having been avoided because saturation steam bulging force and chemical reaction produce the effect of huge bulging force, thereby has prolonged the life-span of hot application slag case system effectively.
In order to make that bolt is easy to connect between connection support 2 and the concrete partition 4; The connecting hole that connects along thickness direction can be set on concrete partition 4; Bolt passes connecting hole, and an end is fixed with being connected support 2, and the other end backing plate 5 outer with being stuck in connecting hole fixed.Normal conditions; Those skilled in the art can make backing plate 5 fasten connecting hole fully; So make connect support 2 with concrete partition 4 between is connected stablely, reliably, can certainly be that backing plate 5 not exclusively fastens connecting hole, need only and can realize identical technique effect.
In addition, those skilled in the art select for use joist steel to support 2 as connecting usually, the preferred I25a that uses in the present embodiment, and two flange plates that will connect support 2 like this are fixing with concrete partition 4 with hot application slag case 1 respectively.
In order to improve the thermal shock resistance of hot application slag system, build refractory brick 3 by laying bricks or stones in the preferred gap between the outer side wall of concrete partition 4 and hot application slag case 1 among the utility model embodiment, can certainly fill other lagging material.
Because the area of the steel plate of hot application slag case 1 sidewall makes that than conference the distortion of hot application slag case 1 is comparatively serious; Thereby make that the life-span of hot application slag case system is lower; Therefore in order further to prolong the life-span of hot application slag case system; Those skilled in the art can hot application slag case 1 height be set to less value, preferably be set to 500mm among the utility model embodiment.Also can be on the basis of the foregoing description that the sidewall thickness setting of hot application slag case 1 is thicker; The wall thickness increase also can slow down the distortion of hot application slag case 1 effectively; Improve the life-span of hot application slag case system, the sidewall thickness of preferred hot application slag case 1 is set to be 50mm among the utility model embodiment.Certainly the height that also is not limited to hot application slag case 1 is set to 500mm, and wall thickness is set to 50mm, as long as can slow down 1 distortion of hot application slag case.
Smooth and easy in order to make that water coolant refluxes, the gradient of bottom interior surface that can hot application slag case 1 is set to 0.03.Water coolant just can flow out comparatively smoothly like this, occurs the accident of setting off firecrackers thereby slowed down high temperature hot application slag because of ponding, has improved hot application slag processing security.
In addition, can also at least two water vents be set in the bottom of hot application slag case 1, with respect to water vent in the prior art, the quantity that increases water vent can be so that water coolant refluxes more smooth and easy; 50 water vents preferably are set among the utility model embodiment; Can also drainage channel be set on water vent, make cooling-water flowing, mediation district and filtration unit can also be set on drainage channel, prevent that drainage channel from stopping up, and prevents that also water coolant from effluxing contaminate environment to preposition.
Usually those skilled in the art can also tamp the ground of hot application slag case 1 bottom, because the ground of hot application slag case 1 bottom is compacting ground, and the pre-buried steel billet in bottom on compacting ground.Thereby damage the ground of hot application slag case 1 bottom when in hot application slag treating processes, avoiding installing slagging-off, and then make the water coolant water exhaust system remain state comparatively smoothly.In the utility model embodiment, the steel billet that section is 150mm * 150mm preferably is set, can certainly adopt the steel billet of other model, as long as can reach identical technique effect.Certainly in the utility model embodiment, can also between the ground of hot application slag case 1 bottom and hot application slag case, fill pebbles.
To the above-mentioned explanation of the disclosed embodiments, be that this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
