Description
Technical field
The present invention relates to a kind of casting transloading equipment, and in particular to a kind of safe transit steel ladle.
Background technology
The existing steel ladle that flue gas material is produced using the filling burning in steel ladle interlayer, the problem for existing is that casting is existing
Field script environment is just more severe, and the operating personnel that the flue gas for producing that burns may only have work high above the ground just can see, and existing
The shop floor worker of field cannot in time know the generation of security incident.
The content of the invention
It is an object of the invention to provide the shop floor worker energy very first time finds the steel ladle of security incident.
The present invention provides base case：A kind of safe transit steel ladle, it is characterised in that including steel ladle body, steel
Water bag body has the molten steel transhipment chamber of epimere opening, and steel ladle originally includes in vivo early warning mechanism, early warning cavity and the pneumatic whistle,
The early warning cavity is located under molten steel transhipment chamber on early warning mechanism, the early warning mechanism include depositing gas passage, inlet suction port,
Air outlet adapter, air gauge and alarm valve, it is described to deposit filled with gases at high pressure in gas passage, it is described to deposit gas channel connection air inlet connecting
Gas passage is deposited in head and air outlet adapter, air gauge connection, the alarm valve include being the valve head of ceramic material, valve rod and
Valve element, valve rod upper end connection valve head, lower connection valve element, the valve head is deposited in gas passage early warning cavity positioned at described, the valve head
With floating chamber, the valve rod is vertically slidable to be connected on steel ladle body, the pneumatic whistle and deposit gas it is logical between be provided with early warning air flue,
The valve element blocks the early warning air flue；The early warning whistle includes the vibration cavity of connection early warning air flue and is arranged in vibration cavity
Vibrating body.
Molten steel injection molten steel transhipment is transported in chamber, and early warning mechanism provides early warning for the leakage for molten steel.Gas passes through air inlet
Joint injection is deposited in gas passage, and gas is discharged by air outlet adapter.Air gauge determines the air pressure deposited in gas passage.Early warning cavity is
The unlatching of early warning valve provides space.There is floating chamber, floating chamber enables the early warning valve of ceramic material to float in molten steel in valve head.Valve
Bar enables early warning valve to slide up and down, and valve element closes under normal circumstances early warning air flue.The pneumatic whistle can send chimes of doom in ventilation,
Gas blows vibrating body, and vibrating body back and forth collides concurrent sound in vibration cavity.
Operation principle：Using front quantitative gas is injected to depositing by inlet suction port in gas passage.Under normal circumstances, inject
After molten steel, when gases are heated, they expand, deposits air pressure in gas passage and rises, but leads to when the side wall that molten steel destroys molten steel transhipment chamber makes to deposit gas
When road is destroyed, gas is revealed by breakage, and air pressure then can diminish, and will so know that steel ladle is destroyed.When molten steel handle
When the lower wall in molten steel transhipment chamber is destroyed, molten steel can then inject early warning cavity, and molten steel is entered after early warning cavity, in the floating valve of molten steel
Head rises, and alarm valve floats, and removes on valve element and opens early warning air flue, and gas enters the pneumatic whistle by early warning air flue, makes vibrating body exist
Vibration cavity internal vibration sounding.
Beneficial effect：1st, this programme has two sets of warning systems, fully ensures that the security during steel ladle use.
When the 2nd, being reported to the police using the pneumatic whistle, the pneumatic whistle for playing a role is relatively easy with the structure of alarm valve, in the ring of high temperature
Also operation can be stablized under border, workman can know the generation of security incident the very first time.
When the 3rd, reporting to the police using air gauge, comparatively fine crack can be sensed, can guarantee that the accuracy of detection.
Scheme two：Based on scheme it is preferred, deposit filling inert gas in gas passage.
Beneficial effect：Inert gas is difficult to be reacted with high-temperature molten steel, it is ensured that will not gas burst when there is accident
With the problem of destruction molten steel property.
Scheme three：For the preferred of scheme two, the early warning mechanism is also including thermometer.Beneficial effect：At identical temperature, one
It is certain to determine mass gas air pressure, and when record is not revealed, the air pressure under uniform temperature can be less than in the event of air pressure is revealed
The value.
Scheme four：For the preferred of scheme three, the gas passage of depositing is covered with steel ladle body in netted.Beneficial effect：Deposit gas
Passage is the netted situation for being covered with steel ladle body, more fully detecting steel ladle body.
Scheme five：For the preferred of scheme four, the vibrating body is spherical, and the pneumatic whistle is steel matter.Beneficial effect：Steel
Material it is elastic good, the spherical elastic vibrating kinetoplast vibration frequency of steel matter is fast, and the sound for sending is bigger.
