Description
Technical field
The utility model is related to vacuum drying oven protector, refers specifically to a kind of vacuum drying oven crucible bleed-out emergency set.
Background technology
Vacuum drying oven is to heat fusing metal under vacuum, then the liquid metal of fusing is poured into formation gold in a mold
Belong to the smelting equipment of ingot casting, due to being chronically in the environment of superhigh temperature, the side wall of crucible can be gradually thinning for crucible in vacuum drying oven,
The phenomenon that bleed-out occurs is easy to, once there is bleed-out phenomenon, serious infringement will be caused to vacuum drying oven, when situation is serious also
Vacuum drying oven explosion can occur, security incident is caused.Existing bleed-out counter-measure mainly has measurement control methods, thermocouple alarm
Method, and electrical parameter control methods.Measurement control methods are that the wall thickness of crucible should be checked after tapping every time, when wall thickness is reduced to
When to a certain degree, stop using, but measurement crucible size change can not find that molten steel penetrates into the dangerous spot of crackle, therefore be not
Very reliable method.Thermocouple warning method starts report when being and running into the molten steel for spilling using the thermocouple for being arranged in vacuum drying oven bottom
Alert program, makes operating system close vavuum pump, and is filled with a large amount of gases, removes vacuum bell, and the molten steel for spilling is poured out, but
In vacuum furnace bottom arrangement bleed-out alarm thermocouple, that is often taken after bleed-out generation prevents arranging for the further expansion of accident
Apply, without prevention and emergency function.Electrical parameter control methods are that electric current, resistance, the power between heat are smelted by observed and recorded
Situation of change predicts the bleed-out problem of crucible, but this Forecasting Methodology is inaccurate, when new furnace lining baking and sintering, sand material
The decomposition of boric acid can cause two intereelectrode short-circuits with volatilization under middle moisture evaporation and high temperature, can cause to report phenomenon by mistake.
The content of the invention
The purpose of this utility model is exactly to overcome the shortcomings of existing for prior art, there is provided a kind of simple structure, is had safely
The vacuum drying oven crucible bleed-out emergency set of effect.
To achieve the above object, the vacuum drying oven crucible bleed-out emergency set designed by the utility model, including vacuum drying oven with
And the crucible in vacuum drying oven is arranged on, the bottom of vacuum drying oven is provided with blind hole, wherein, special-shaped funnel is provided with below crucible, abnormity
Funnel includes the charging aperture of upper end and the discharging opening of lower end, and diversion cavity is formed between charging aperture and discharging opening；Charging aperture and crucible
Bottom correspondence, discharging opening is downwardly extending delivery line, and delivery line is sheathed in blind hole, and aluminium sheet is provided with the opening of delivery line
Plug, aluminium sheet plug lower section is provided with ingot mould.
Further, the left side wall of the diversion cavity is the vertical plane perpendicular to vacuum drying oven bottom surface, left side wall and discharging
Mouthful connected by changeover portion, changeover portion is fitted in vacuum drying oven bottom surface and vertical with left side wall；The right side wall of diversion cavity be with very
Empty stove bottom surface inclined-plane at an acute angle, vacuum drying oven bottom surface is provided with the bearing of support right side wall.
Further, the right side wall is corresponding with the bottom surface of crucible.
The beneficial effects of the utility model are：
1, the utility model sets special-shaped funnel below crucible, once crucible occurs breakage, is spilt from crucible bottom
Molten steel is guided to outside vacuum drying oven by special-shaped funnel, and destruction of the bleed-out to vacuum furnace body is avoided to the full extent.
2, the delivery line of special-shaped funnel is sheathed in the blind hole of vacuum drying oven, take full advantage of blind hole structure on vacuum drying oven without
The other processing of body of heater need to be reduced cost and be avoided to vacuum drying oven structural damage.
3, special-shaped funnel left side side wall is straight with vacuum drying oven dolly, and vacuum drying oven bottom surface is provided with the bearing of support right side wall,
This structure is conducive to special-shaped funnel to be stably placed on vacuum drying oven.And right sidewall forms acute angle bevel with vacuum drying oven bottom,
Be conducive to dropping down onto delivery line under the molten steel for spilling.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Each part numbers are as follows in figure：Vacuum drying oven 1, crucible 2, special-shaped funnel 3, charging aperture 4, discharging opening 5, delivery line 6, lead
Stream chamber 7, aluminium sheet plug 8, ingot mould 9, left side wall 10, changeover portion 11, right side wall 12, bearing 13, blind hole 14.
Specific embodiment
To more fully understand the utility model, utility model is carried out specifically below with reference to accompanying drawing and instantiation
It is bright.
Such as Fig. 1, vacuum drying oven crucible bleed-out emergency set, including vacuum drying oven 1 and the crucible 2 that is arranged in vacuum drying oven 1, very
The bottom of empty stove 1 is provided with blind hole 14, wherein, the lower section of crucible 2 is provided with special-shaped funnel 3, and special-shaped funnel 3 includes the charging aperture of upper end
4, the discharging opening 5 of lower end forms diversion cavity 7 between charging aperture 4 and discharging opening 5；Charging aperture 4 is corresponding with the bottom of crucible 2, described
Discharging opening 5 is downwardly extending delivery line 6, and the delivery line 6 is sheathed in blind hole 14, and aluminium sheet is provided with the opening of delivery line 6
