Abstract
The utility model relates to a sealed explosion-proof door for furnaces. An impact-proof tank is welded on a press cover; the press cover, an explosion-proof film and an asbestos shim plate are fixed on a door frame plate by bolts and nuts; the heat-insulating material is formed by four blocks, and the heat-insulating material is fixed by two sash bars; the explosion-proof film is rectangular, and the scratch of the explosion-proof film is in a shape like the Chinese character ' wang '; the seam of the thermal insulating material is consistent with the scratch of the explosion-proof disc; the edges of the inner sides of the press cover and the impact-proof tank are tangential with the outer edge of the scratch of the explosion-proof film. The explosion-proof film is impacted to open by the pressure in the stove and the impact-proof tank can contain debris when explosion happens, and the pressure in the stove is not influenced to be exhausted in time. The heat-insulating material, the explosion-proof film, etc., are replaced by assembling and disassembling the bolts and the nuts.
Description
The utility model relates to a kind of heating furnace with sealing explosion vent apparatus, belongs to the corollary apparatus of full-sealing energy-saving type heating furnace.
The explosion proof door structure that present heating furnace device generally uses mainly is to seal by inclined-plane gravity as shown in Figure 1, and explosion-proof door closure is connected with a screw rod with doorframe, can wash explosion-proof door closure open after stressed effect in the stove, reaches the purpose of pressure release.Because the radiation chamber negative pressure is very big, it is very serious that this apparatus structure leaks, and is incubated also relatively poor.At the problems referred to above, people have proposed some and have improved, and Fig. 2 is the circular explosion proof door that has rupture pressure disc, because without inclined-plane gravity sealing and increased rupture pressure disc, asbestos dividing plate, and with the fixing explosion proof door of bolt and nut, and have the erosion control case, sealing or reasonable, when being subjected to furnace pressure, wash explosion proof door open by heat insulating block, but because rupture pressure disc is rounded, cut is " ten " font (shown in Fig. 2 a), occur the dead angle during explosion easily, explosion is under some influence.In addition, this kind explosion proof door is owing to structural reason, and flexibly thermal insulation materials such as the good refractory fibre of heat-proof quality are placed in inconvenience, have to soon and the asbestos dividing plate is heat insulation by insulation, heat-proof quality is poor, owing to rupture pressure disc is generally all made by aluminium sheet, be easy to overtemperature, service life is shorter.
The purpose of this utility model is that a kind of improved heating furnace sealing explosion vent apparatus will be provided, this explosion vent apparatus good sealing effect, and explosion does not have the dead angle, and is heat insulation good, and it is convenient to change, long service life.
The purpose of this utility model is achieved in that the erosion control case is welded on the gland, with bolt and nut rupture pressure disc, asbestos backing plate, gland are fixed, heat-barrier material is made up of four blocks of flexible materials and is fixed with two mouldings that are welded on the Door frame board, rupture pressure disc is rectangular, its cut is " king " font, the seam of heat-barrier material and rupture pressure disc cut coincide, the outward flange of the inside edge of gland and erosion control case and rupture pressure disc cut is tangent, by furnace pressure rupture pressure disc is washed open during explosion, the erosion control case is enough to hold the fragment of explosion, can not influence the timely drainage of furnace pressure.When ressembling, as long as with four blocks of heat-barrier materials, rupture pressure disc successively installs and gets final product.
The utility model explosion vent apparatus is because use rupture pressure disc, and with bolt and nut explosion proof door fixed, so good sealing effect does not leak basically; Because rupture pressure disc is a rectangle, the rupture pressure disc cut is " king " font, so explosion does not have the dead angle, can all open again; Also, change conveniently so install because heat-barrier material is fixed by two mouldings; This kind explosion proof door structure to heat-barrier material without limits, the good flexible material of available heat-proof quality, thereby the service life of having improved rupture pressure disc greatly.In addition, the explosion vent apparatus of this structure not only can be used for the malleation stove and also can be used for the negative pressure stove, can be according to different burst pressures, and temperature in the different stoves is selected different models.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1, be prior art explosion vent apparatus front view, wherein, the explosion-proof door closure of 1-, 2-connecting screw rod.
Fig. 1 a is Fig. 1 explosion vent apparatus side sectional view.
Fig. 2 is the circular explosion vent apparatus side sectional view of prior art band rupture pressure disc, 3-rupture pressure disc wherein, 4-asbestos dividing plate, 5-heat-barrier material, 6-gland, 7-erosion control case, 8-impingement baffle.
Fig. 2 a is Fig. 2 rupture pressure disc front view, 9-cut wherein, 10-blast area.
Fig. 3 is according to the explosion vent apparatus side sectional view that the utility model proposes, 11-moulding wherein, 12-Door frame board, 13-spilled water hole, 14,15-bolt, nut, 16-reinforcement, 17-furnace wall.
Fig. 3 a is Fig. 3 rupture disk device part section front view.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
The utility model device is mainly by an erosion control case (7), gland (6), and rupture pressure disc (3), asbestos backing plate (4), heat-barrier material (5), moulding (11), Door frame board (12), spiral shell inspection nut (14,15) and reinforcement (16) are formed.
Erosion control case (7) is welded on the gland (6), gland (6), rupture pressure disc (3) and asbestos backing plate (4) are fixed on the Door frame board (12) with bolt and nut (14,15), and strengthen this structure with reinforcement (16), heat-barrier material (5) is formed by four, and fixing with slip-off preventing with two mouldings (11) that are welded on the Door frame board (12).Rupture pressure disc (3) is rectangular, its cut is " king " font, the seam of four blocks of heat-barrier materials (5) and rupture pressure disc cut (9) coincide, the outward flange of the inside edge of erosion control case (7) and gland (6) and rupture pressure disc cut (9) is tangent, furnace pressure is washed rupture pressure disc (3) open during explosion, the fragment of erosion control case (7) when being enough to hold explosion can not influence the timely drainage of stove internal gas pressure.When ressembling, the bolt and nut (14,15) of dismantling earlier, take away the rupture pressure disc (3) after gland (6) and erosion control case (7), the explosion, take down heat-barrier material, then as long as with preprepared four blocks of heat-barrier materials (5), rupture pressure discs (3) etc. are successively good and sound, and shimming is twisted good bolt and nut (14,15) and got final product.When changing heat-barrier material,, use two mouldings as long as damaging not serious just can the continuation.
