Description
Technical field
It the utility model is related to drying plant technical field, more particularly to a kind of cartridge heater heat-proof device of hot-blast stove.
Background technology
Drying chamber is widely used device in coating equipment.The part of core is hot-blast stove in drying chamber, the heat of drying
Air is all derived from secondary.Due to carrying out the burning of the gases such as natural gas, heat exchanger in heat exchanger of the burner in hot-blast stove
The insulation at place needs emphasis to consider with heat-insulated.Because hot-blast stove wallboard is all monoblock type, the ground of heat and heat transfer is easily leaked
Side is just at the position that burner connects with burning bucket, but existing insulation and heat-insulated effect are poor, and connecting portion holds
It is easy to crack.
Utility model content
The purpose of this utility model is to provide a kind of cartridge heater heat-proof device of hot-blast stove, solve it is of the prior art every
Heat and heat insulation effect are poor, and the technical problem that passage of flame easily ftractures.
A kind of cartridge heater heat-proof device of hot-blast stove, including burner, burning cylinder, passage of flame and hot-blast stove heat insulation wall
Plate, the end set combustor nozzle of the burner, the burning cylinder are connected with the passage of flame, the burner
Burner is arranged on inside passage of flame, and the passage of flame is hollow core structures, and passage of flame is internally provided with high temperature resistant filling
Layer, the passage of flame are located in hot-blast stove heat insulation wall intralamellar part.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement：
Further, the passage of flame includes direct tube section and round platform section, the combustor nozzle and the direct tube section phase
Coordinate, the round platform section is located on the outside of the combustor nozzle, and the beneficial effect using this step is by round platform section, can be avoided
Flame directly scorches to passage, can so prevent passage from ftractureing.
Further, gap is left between the outer wall of the inwall of the direct tube section and the combustor nozzle, using this step
Beneficial effect be prevent directly contact cause passage to ftracture.
Further, the outer diameter of the round platform section is less than inner diameter.
Further, it also includes shrouding, and the seal plate welding is in the end of direct tube section.
The beneficial effects of the utility model：
The utility model is a kind of cartridge heater heat-proof device of hot-blast stove, plays heat-blocking action；Flame of the present utility model
Passage has round platform section, can so avoid flame from directly scorching, so as to increase the service life；The utility model utilizes high temperature resistant
Packed layer, effect of heat insulation can be improved, so as to prevent hot-blast stove heat insulation wall plate temperature too high；The utility model is simple in construction, every
Thermal effect, and service life is grown.
Brief description of the drawings
, below will be right in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
The required accompanying drawing used is briefly described in embodiment or description of the prior art, it should be apparent that, describe below
In accompanying drawing be some embodiments of the present utility model, for those of ordinary skill in the art, do not paying creativeness
On the premise of work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of the cartridge heater heat-proof device of hot-blast stove described in the utility model specific embodiment 1
Figure；
Reference：
1- burners；2- burning cylinders；3- passage of flames；4- hot-blast stoves are incubated wallboard；5- combustor nozzles；6- high temperature resistants
Packed layer；7- direct tube sections；8- round platform sections；9- shroudings.
Embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described
Embodiment is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, sheet
The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality
Novel protected scope.
Embodiment 1
As shown in figure 1, a kind of cartridge heater heat-proof device of hot-blast stove provided by the utility model, including burner 1, combustion
Burn cylinder 2, passage of flame 3 and hot-blast stove insulation wallboard 4, the end set combustor nozzle 5 of the burner 1, the burning
Cylinder 2 is connected with the passage of flame 3, and the combustor nozzle 5 is arranged on inside passage of flame 3, and the passage of flame 3 is
Hollow core structures, and passage of flame is internally provided with high temperature resistant packed layer 6, existing passage of flame generally all to be solid, so holds
Easy heat conduction, heat-insulated effect is not had；The passage of flame 3 is located in inside hot-blast stove insulation wallboard 4.
Wherein, the passage of flame 3 includes direct tube section 7 and round platform section 8, the combustor nozzle 5 and the phase of direct tube section 7
Coordinate, the round platform section 8, by round platform section 8, can avoid flame from directly entering to passage positioned at the outside of combustor nozzle 5
Row scorches, and can so prevent passage from ftractureing.
Wherein, gap, combustor nozzle 5 are left between the inwall of the direct tube section 7 and the outer wall of the combustor nozzle 5
When in use, temperature is very high, if passage of flame directly contacts, it is easy to because temperature is too high, causes passage to ftracture.
Wherein, the outer diameter of the round platform section 8 is less than inner diameter, and the left side diameter of round platform section is less than right side diameter,
The diameter of so round platform section becomes larger, and so as to effectively prevent flame from directly scorching vias inner walls, makes so as to extend
Use the life-span.
Wherein, it also includes shrouding 9, and the shrouding 9 is welded on the end of direct tube section 7, now fills high temperature resistant packed layer 6
To passage of flame 3, then sealed again with shrouding 9, so as to improve stability.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
