Description
Technical field
The utility model relates to a kind of fast turn on the gas bleeding device that surges of vapourizing furnace.
Background technology
What current domestic metallurgical vapourizing furnace diffused act as after plant pressure surpasses the upper limit, and can automatically open, relief pressure guarantees safety.But when factory's damping down changes air port, the general vapourizing furnace bypass that uses is diffused, and with regulating tuyere negative pressure, reaches the object that safety changes air port.But this sealing effectiveness diffusing safely by-pass valve is poor, and gas leak rate reaches 3%, under the gas leak of vapourizing furnace height top pressure, high temperature and high dust-laden is washed away, the life-span of bypass diffusion valve is shorter, and valve leak becomes the bottleneck of restriction plant produced and safety.
Summary of the invention
The purpose of this utility model is the fast turn on the gas bleeding device that surges providing a kind of vapourizing furnace, can combine with bypass diffusion valve and jointly use, make up the defect that it can not seal, stop gas leakage, prevent the generation of coal gas accident, ensure safety in production, surge simultaneously and diffuse hole also there is resistant to elevated temperatures function.
The purpose of this utility model is achieved in that a kind of fast turn on the gas bleeding device that surges of vapourizing furnace, comprise hole seat and port lid, seat lower end, hole affixed a cone joint, on the seat lower end inner wall of hole by one piece of annulus shrouding interval affixed a cylinder, cylinder and hole seat coaxial line, cylinder inner wall is arranged flame retardant coating, on the sidewall of seat lower end one, hole, horizontal tangential arranges an air inlet port, in annular space between cylinder and hole seat inwall, spiral guiding plate is set from down to up, seat another sidewall in hole arranges armed lever seat, the articulated armed lever in armed lever seat top, armed lever one end and port lid end face hinged, the cylinder rod top that the armed lever the other end and one vertically arrange is hinged, under port lid, between end flanges and seat top, hole flange, one_to_one corresponding arranges threaded hole and joint bolt uniformly at intervals respectively, sealing-ring is set between flange face, the apical position of described cylinder is higher than the position of sealing-ring.
As further improvement of the utility model, in the top of each joint bolt described, strip hole is vertically set respectively, in each strip hole, is interspersed with swash plate wedge respectively.
The utility model is installed on the diffusion mouth end of vapourizing furnace bypass diffusion valve, and according to service routine, after factory stops, open before safe bypass diffuses, first opening surges diffuses aperture apparatus.After the multiple wind of factory, close after safe bypass diffuses, then close to surge and diffuse aperture apparatus.Utility model works environment is high-pressure high-temperature environment, in seat bottom, hole, threaded hole through hole is set and inwall tangent, threaded hole screws in screw thread short circuit and passes into cooling gas, cooling gas is derived by the top of threaded hole top spiral guiding plate spiral to inwall, plays Homogeneous cooling and surges and diffuse the object of aperture apparatus.Inwall exceeds edge on port lid flange simultaneously, after cooling gas rises, can extend its practical life by cooling forming pad simultaneously.Pouring into a mould resistance to material at inwall has resistant to elevated temperatures function equally simultaneously.The utility model is combined with bypass diffusion valve and is jointly used, and makes up the defect that it can not seal, stops the leakage of coal gas, prevent the generation of coal gas accident, ensure safety in production, make the production of metallurgical furnace more stable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view
Fig. 2 is the partial enlargement structural representation in the utility model Fig. 1.
Embodiment
A kind of fast turn on the gas bleeding device that surges of vapourizing furnace, as Fig. 1, shown in Fig. 2, comprise hole seat 1 and port lid 6, hole seat 1 lower end affixed a cone joint 13, on hole seat 1 lower end inner wall by one piece of annulus shrouding 15 interval affixed a cylinder, cylinder and hole seat coaxial line, cylinder inner wall is arranged flame retardant coating 14, on the sidewall of hole seat 1 lower end one, horizontal tangential arranges an air inlet port 16, in annular space between cylinder and hole seat inwall, spiral guiding plate 17 is set from down to up, seat another sidewall in hole arranges armed lever seat 11, the articulated armed lever 7 in armed lever seat 11 top, armed lever 7 one end and port lid 6 end face hinged, cylinder rod 20 top that the armed lever the other end and one vertically arrange is hinged, under port lid, between end flanges and seat top, hole flange 4, one_to_one corresponding arranges threaded hole and joint bolt 2 uniformly at intervals respectively, sealing-ring 9 is set between flange face, the apical position of described cylinder 18 is higher than the position of sealing-ring 9.
As further improvement of the utility model, as shown in Figure 1 and Figure 2, in the top of each joint bolt 2 described, strip hole 19 is vertically set respectively, in each strip hole 19, is interspersed with swash plate wedge 5 respectively.
