Interior pipe is gripped by the clamping part of strut member, and roller is against on the inwall of outer tube, thus completes the fixing of interior pipe, installing/dismounting is all very convenient, when interior pipe or outer tube damage, only need to be changed one of them, during dismounting, also another one can not be damaged, thus advantage of lower cost is changed, after adopting above-mentioned installation structure, compared to existing technology, without the need to being welded and fixed, decrease the distortion amount of inner and outer tubes welding.
Having arc on roller described in the utility model, this arc mates with outer tube wall. Roller, by its arc, can be fitted with outer tube wall more, and its support effect is better.
Strut member described in the utility model comprise each other symmetrically arranged upper slice and bottom sheet, described upper slice comprise the holding tank in spill and be separately positioned on the installation arm of holding tank both sides, between the installation arm that described roller is arranged on slice and the installation arm of bottom sheet, the holding tank of described upper slice holding tank and bottom sheet forms described clamping part. The interior pipe of the applicable different tube diameters of holding tank, it is applied widely.
The utility model also comprises standing bolt, and described standing bolt passes the installation arm of upper slice installation arm, roller and bottom sheet successively and fixed by roller.
The utility model is compared with prior art, have the following advantages and effect: structure is simple, reasonable in design, interior pipe is gripped by the clamping part of strut member, and roller is against on the inwall of outer tube, thus completing the fixing of interior pipe, installing/dismounting is all very convenient, when interior pipe or outer tube damage, only need to change one of them, during dismounting, also can not damage another one, thus change advantage of lower cost, after adopting above-mentioned installation structure, compared to existing technology, it is not necessary to be welded and fixed, the distortion amount of inner and outer tubes welding is decreased.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, it is briefly described to the accompanying drawing used required in embodiment or description of the prior art below, obviously, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the combustion gas twin wall emitter lateral structure peculiar to vessel in the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
Embodiment 1
See Fig. 1, the combustion gas twin wall emitter lateral structure peculiar to vessel of the present embodiment comprises interior pipe 1, outer tube 2 and the strut member 3 for being fixed in outer tube 2 by interior pipe 1.
Strut member 3 in the present embodiment comprises the clamping part 31 being clamped in interior pipe 1 outer wall and the two groups of support portions 32 being positioned at clamping part 31 both sides, and support portion 32 is provided with roller 33, and roller 33 is against on the inwall of outer tube 2 and can roll along outer tube 2 inwall. Interior pipe 1 axially can be moved freely along outer tube 2 by roller 33, is convenient to install or change.
Interior pipe 1 is gripped by the clamping part 31 of strut member 3, and roller 33 is against on the inwall of outer tube 2, thus completes the fixing of interior pipe 1, installing/dismounting is all very convenient, when interior pipe 1 or outer tube 2 damage, only need to be changed one of them, during dismounting, also another one can not be damaged, thus advantage of lower cost is changed, after adopting above-mentioned installation structure, compared to existing technology, without the need to being welded and fixed, decrease the distortion amount of inner and outer tubes welding.
Having arc 331 on roller 33 in the present embodiment, this arc 331 mates with outer tube 2 inwall. Roller 33, by its arc 331, can be fitted with outer tube 2 inwall more, and its support effect is better.
