Abstract
The utility model discloses a self -bleeding explosion -proof equipment of high temperature non -pressure carborundum fritting furnace, the device are located horizontal high temperature furnace stove outer covering outside or vertical high temperature furnace head outside, its characterized in that: the lower extreme is taken over through internal intercommunication of welding and high temperature furnace to explosion -proof valve, pass through the flange intercommunication with long -pending trachea lower extreme on explosion -proof valve is taken over, it is middle sealed with first sealing washer with the lower flange to go up the flange, and flange joint department is fixed with a fasteners, long -pending trachea upper end is connected with dull and stereotyped through the flange, and is sealed with the second sealing washer between flange and the flat board, and the flange has compression spring's the 2nd fasteners fixed with dull and stereotyped junction with the overcoat. When malleation pressure was greater than 0.4MPa in the high temperature furnace, explosion -proof valve flat board will be by jack -up, gaseously discharged rapidly through long -pending trachea, for furnace body exhaust pressure release to play the blast proof effect of high temperature furnace, the security is higher.
Description
Technical field
The utility model relates to explosion-protection equipment, particularly relates to the automatic vent explosion-protection equipment of a kind of pyrocarbon SiClx sintering furnace with no pressure.
Background technology
Carborundum, Graphene, graphite film, battery positive/negative material are obtained in corresponding high temperature furnace, its required reaction temperature up to 1800-3100 degree Celsius, and produce under being in the inert gas of pressure-fired 0.1-0.4MPa and there is potential safety hazard.Existing explosion-protection equipment has two kinds: a kind of is the explosion-proof rubber adopted, and its principle utilizes the air pressure in body of heater to be crushed by rubber slab, and shortcoming is that explosion-proof pressure size is uncontrollable, the life-span is short, needs often to overhaul; Another adjusts gas flow by instrumentation, shortcoming be electrical instrumentation be easy on intermediate frequency high temperature furnace produce interference you break down, also there is retardance, there is very large security risk.
Utility model content
For overcoming the deficiency of the problems referred to above, the utility model provides a kind of automatic vent explosion-protection equipment of high temperature pressure-free carborundum sintering furnace.
For achieving the above object, the utility model adopts following technical scheme: a kind of automatic vent explosion-protection equipment of high temperature pressure-free carborundum sintering furnace, this device is positioned at horizontal-type high temperature stove furnace shell outside or vertical high-temperature stove end socket outside, it is characterized in that: described explosion-protection equipment comprises explosion-proof valve adapter, gas-accumulating tube, flat board, the first sealing ring, the second sealing ring, Compress Spring, the first fastening connection piece, the second fastening connection piece, explosion-proof valve adapter lower end is communicated with high-temperature furnace body inside by welding; Explosion-proof valve adapter upper end is communicated with by flange with gas-accumulating tube lower end, and seal with the first sealing ring in the middle of upper flange and lower flange, flange connections the first fastening connection piece is fixed; Gas-accumulating tube upper end is connected with flat board by flange, and with the second sealing ring sealing between flange and flat board, flange and dull and stereotyped junction overcoat have the second fastening connection piece of Compress Spring to fix.
Preferred: described first fastening connection piece is bolt.
Preferred: described second fastening connection piece is bolt.
The utility model beneficial effect is: when in high temperature furnace, positive pressure pressure is greater than 0.4MPa, and explosion-proof valve flat board will by jack-up, and gas is discharged rapidly by gas-accumulating tube, is body of heater exhaust pressure relief, thus plays the explosion-proof effect of high temperature furnace, and security is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model product.
Fig. 2 is the top view of the utility model product.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model and detailed description of the invention thereof are described in further detail.
Fig. 1 is a preferred embodiment of the present utility model.As shown in the figure: a kind of automatic vent explosion-protection equipment of high temperature pressure-free carborundum sintering furnace, this device is positioned at horizontal-type high temperature stove furnace shell outside or vertical high-temperature stove end socket outside, described explosion-protection equipment comprises explosion-proof valve adapter 1, gas-accumulating tube 2, dull and stereotyped 8, first sealing ring 5, second sealing ring 9, Compress Spring 10, first fastening connection piece 6, second fastening connection piece 11, and explosion-proof valve adapter 1 lower end is communicated with namely identical with the pressure in body of heater by welding with high-temperature furnace body inside.Explosion-proof valve adapter 1 upper end is communicated with by flange with gas-accumulating tube 2 lower end, seals in the middle of upper flange 4 and lower flange 3 with the first sealing ring 5, and flange connections the first fastening connection piece 6 is fixed, thus ensures gas-accumulating tube 2 and communicate in body of heater and external seal.Gas-accumulating tube 2 upper end is connected with dull and stereotyped 8 by flange 7, seals between flange 7 and dull and stereotyped 8 with the second sealing ring 9, and flange 7 and dull and stereotyped 8 junction overcoats have the second fastening connection piece 11 of Compress Spring 10 to fix.
Preferably, above-mentioned first fastening connection piece 6 and the second fastening connection piece 11 are bolt.
When in high temperature furnace, positive pressure pressure is greater than 0.4MPa, gas-accumulating tube 2 is equal with the pressure that communicates in body of heater, dull and stereotyped 8 will by jack-up, Compress Spring 10 is compressed, gas is discharged by the outward opening of gas-accumulating tube 2 upper end with flat board 8, be body of heater exhaust pressure relief rapidly, thus the effect that the step-down serving high temperature furnace is explosion-proof.
Automatic vent explosion-protection equipment described in the utility model specifically may be used on horizontal-type high temperature silicon carbide furnace, vertical high-temperature graphitizing furnace, horizontal-type high temperature carbide furnace.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
