Description
Technical field
The utility model relates to smelting equipment, is specifically related to a kind of explosion-protection equipment of heating furnace.
Background technology
Existing explosion-protection equipment is generally that opening part arranges Explosion-proof cap in the pipeline upper shed, and abnormal when too high at the stove internal gas pressure, Explosion-proof cap is washed open by gas and played a protective role, and after the stove internal gas pressure was normal, manual operation made Explosion-proof cap return to closed condition.But this explosion-protection equipment can not automatically reset and cut out after Explosion-proof cap is opened, must manual operation just can close, open in case operating personnel can not in time find Explosion-proof cap, in time Explosion-proof cap be closed, normal operation with having a strong impact in heating furnace makes troubles to production.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of heating furnace explosion-protection equipment that automatically resets and close.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of heating furnace explosion-protection equipment, comprise the pipeline with turning, one end of described pipeline communicates with the furnace chamber passage, the other end communicates with discharge flue, be provided with venting on this pipeline, the venting place is provided with the Explosion-proof cap that can fill in venting, it is characterized in that, is provided with the resetting structure that can make Explosion-proof cap automatically fill in venting in the outside of described Explosion-proof cap.
The beneficial effects of the utility model: the utility model due in the arranged outside of Explosion-proof cap automatic reset structure, after Explosion-proof cap is opened because the heating furnace internal pressure is excessive, without manual operation, Explosion-proof cap just will automatically reset and close, can not affect the normal operation in heating furnace, bring facility to safety in production.
Further, described resetting structure is extension spring, first connecting rod and the second connecting rod that is arranged on the Explosion-proof cap outside, and extension spring is connected with first connecting rod, and first connecting rod and second connecting rod are hinged, second connecting rod is fixedly connected on pipeline, also is provided with another extension spring between first connecting rod and second connecting rod.This resetting structure is simple, and homing action is rapid, and is safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
as shown in Figure 1, the heating furnace explosion-protection equipment, comprise the pipeline 1 with turning, one end of pipeline 1 communicates with furnace chamber passage 2, the other end communicates with discharge flue 3, be provided with venting 4 on this pipeline 1, venting 4 has oral area, the place is provided with a circle sealing ring 6 at oral area, venting 4 places are provided with the Explosion-proof cap 5 that can fill in venting, be provided with the resetting structure that can make Explosion-proof cap 5 automatically fill in venting 4 in the outside of described Explosion-proof cap 5, as a kind of optimal way, described resetting structure is the extension spring 9 that is arranged on the Explosion-proof cap outside, first connecting rod 8 and second connecting rod 7, extension spring 9 is connected with first connecting rod 8, first connecting rod 8 is hinged with second connecting rod 7, second connecting rod 7 is fixedly connected on pipeline 1, wherein, also be provided with another extension spring 10 between first connecting rod 8 and second connecting rod 7.
Above-described is only preferred embodiment of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
