Abstract
The utility model relates to smelting equipment, in particular to a smelting furnace explosion-proof device. The smelting furnace explosion-proof device comprises a pipeline with corners. One end of the pipeline is communicated with a furnace chamber channel, and the other end of the pipeline is communicated with a smoke-removing channel. An explosion-proof opening is placed on the pipeline. An explosion-proof cover is placed outside the explosion-proof opening. The smelting furnace explosion-proof device is characterized in that the explosion-proof opening is provided with a mouth portion. The explosion-proof cover is hinged on the rim of the mouth portion. A tension spring is placed inside the explosion-proof cover, and is fixedly connected on the rim of the mouth portion. The smelting furnace explosion-proof device overcomes the defects that normal operations in the furnace are affected because the explosion-proof cover can not be timely closed.
Description
Technical field
The utility model relates to smelting equipment, is specifically related to a kind of explosion-protection equipment of smelting furnace.
Background technology
Normally in the pipeline upper shed, opening part arranges Explosion-proof cap to the explosion-protection equipment of smelting furnace, and when the stove internal gas pressure was too high, Explosion-proof cap was washed open 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, and must manual operation just can complete, and opens in case operating personnel can not in time find Explosion-proof cap, in time Explosion-proof cap is closed, with the normal operation that has a strong impact in heating furnace.
The utility model content
But the technical problems to be solved in the utility model is the explosion-protection equipment of the smelting furnace of autoshutdown after Explosion-proof cap is opened.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of smelting furnace explosion-protection equipment, comprise the pipeline with turning, one end of described pipeline communicates with the furnace chamber passage, and the other end communicates with discharge flue, is provided with venting on this pipeline, venting is provided with Explosion-proof cap outward, it is characterized in that, venting has oral area, and Explosion-proof cap is articulated in the edge of oral area, the Explosion-proof cap inboard is provided with extension spring, and this extension spring is fixedly connected on described oral area edge.
The beneficial effects of the utility model: because the oral area edge of Explosion-proof cap and venting is hinged, the Explosion-proof cap inboard is provided with extension spring, extension spring has the effect of restoring force to the inside all the time to Explosion-proof cap, therefore, in the normal situation of smelting furnace internal pressure, Explosion-proof cap will cover venting, when the smelting furnace internal pressure is excessive, Explosion-proof cap will be rushed to open, play explosion-proof effect, after Explosion-proof cap is rushed to open, due to the effect of the restoring force of extension spring, Explosion-proof cap will cover automatically, and having overcome because Explosion-proof cap can not in time cover affects the normal drawback of moving in stove.
Further, be provided with a circle sealing ring at described oral area.When sealing ring is closed at Explosion-proof cap, effectively prevent the Leakage Gas in heating furnace, strengthen the security of heating furnace.
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:
Smelting furnace explosion-protection equipment as shown in Figure 1, comprise the pipeline 1 with turning, one end of described pipeline 1 communicates with furnace chamber passage 2, and the other end communicates with discharge flue 3, is provided with venting 4 on this pipeline 1, venting 4 has oral area, this oral area place is provided with a circle sealing ring 6, and venting 4 is outer is provided with Explosion-proof cap 5, and Explosion-proof cap 5 is articulated in the edge of oral area by hinge 8, Explosion-proof cap 5 inboards are provided with extension spring 7, and this extension spring 7 is fixedly connected on described oral area edge.
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.
Claims (2)
