3be not stained with aluminium material, enable to be stored in 650 DEG C of interior aluminium liquid and be well incubated.When air injection machine needs aluminum liquid filling type, system, to injecting compressed air in holding furnace, makes aluminium liquid inject the mold cavity of air injection machine by stalk.In this cavity filling process, the heat in holding furnace can run off, then need the electric heater for heating in holding furnace, makes the aluminium liquid in holding furnace maintain about 650 DEG C.Weak point: after the aluminium liquid 1, in holding furnace exhausts, needs again to add aluminium liquid in holding furnace, and within this time period again adding aluminium liquid, air injection machine is halted state always, can not produce by continuous print, causes waste of time.2, outside aluminium liquid is poured in holding furnace, and aluminium liquid does not effectively leave standstill and filters, and include a lot of oxide impurity, air injection machine directly utilizes the aluminium liquid cast article in holding furnace, easily produces defective product.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of three Room continuous pressure aluminium liquid electrical heating holding furnaces, Fen Liangge operating room and a rest chamber, Liang Ge operating room provides aluminium liquid to use to two air injection machines respectively, rest chamber stores a certain amount of aluminium liquid and carries out leaving standstill filtration, when Liang Ge operating room aluminium liquid separately uses, respectively by operating room separately with the breach of rest chamber UNICOM, aluminium liquid in rest chamber utilizes the gravity of self to flow to operating room, well ensure that operating room provides aluminium liquid to air injection machine continuously, air injection machine is enable to realize continuous seepage.
Technical scheme of the present invention is achieved in the following ways: three Room continuous pressure aluminium liquid electrical heating holding furnaces, comprise Liang Ge operating room and a rest chamber, stalk and immersion heating tube is provided with in described operating room I and operating room II, degasification rod and immersion heating tube is provided with in rest chamber, two side lower parts of rest chamber have breach, the upper end of breach is provided with stopper and stopper seat, it is characterized in that: the connection of described rest chamber and two operating rooms is realized by the pressing of stopper and stopper seat, the breach connected between rest chamber and Liang Ge operating room is drive stopper to block the stopper be located on breach downwards by cylinder II respectively, stopper half-twist is driven to block breach by cylinder I again, oxide impurity is rolled, ensure that binding face seals completely.
Described cylinder II drives stopper downward, stopper and the laminating of stopper seat, blocks the breach between rest chamber and operating room I or operating room II.
Described cylinder I drives stopper half-twist, and the oxide impurity of indentation, there is rolled, and ensures that binding face seals completely.
An aluminium liquid liquid level sensor is had, for spending most when detecting aluminium liquid liquid level in described operating room I and operating room II.
Described operating room I and operating room II can work simultaneously, also can not simultaneously work.
The present invention, adopts immersion heating technique, and the most effective directly heat conduction, to aluminium liquid, saves the energy; The oxide generated reduces, and guarantees the cleannes of aluminium liquid.When Liang Ge operating room aluminium liquid separately uses, respectively by operating room separately with the breach of rest chamber UNICOM, aluminium liquid in rest chamber utilizes the gravity of self to flow to operating room, well ensure that operating room provides aluminium liquid to air injection machine continuously, enable air injection machine realize continuous seepage.The situation that three Room holding furnaces are put side by side for two low-pressure machine, saves more space and the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the I enlarged drawing of stopper and breach.
Detailed description of the invention
Known by Fig. 1, three Room continuous pressure aluminium liquid electrical heating holding furnaces, three Room holding furnace shells are formed by iron plate integral solder, comprise Liang Ge operating room and a rest chamber 6, stalk 2 and immersion heating tube 9 is provided with in described operating room I 1 and operating room II8, degasification rod 7 and immersion heating tube 9 is provided with in rest chamber 6, two side lower parts of rest chamber 6 have breach 12, the upper end of breach 12 is provided with stopper 10 and stopper seat 11 by stopper seat 11, described rest chamber 6 and the connection of two operating rooms are realized by stopper 10 pressing, breach 12 between UNICOM's rest chamber 6 and Liang Ge operating room is that cylinder II 5 drives stopper 10 to block the stopper 11 be located on breach 12 downwards respectively, stopper 10 half-twist is driven to block breach 13 by cylinder I 4 again, oxide impurity is rolled, ensure that binding face seals completely.
Being known by Fig. 2, is stopper and breach schematic diagram.Cylinder II 5 drives stopper 10 downward, and stopper 10 and stopper seat 11 are fitted, and blocks the breach between rest chamber 6 and operating room I 1 or operating room II8; Cylinder I 4 drives stopper 10 half-twist, and the oxide impurity at breach 12 place is rolled, and ensures that binding face seals completely.An aluminium liquid liquid level sensor 3 is had, for spending most when detecting aluminium liquid liquid level in described operating room I 1 and operating room II8.
Three described Room holding furnace shells are formed by iron plate integral solder, there are heat-insulation layer and working lining successively from outside to inside, according to the coefficient of heat transfer of heat-insulation layer and working lining, calculate the thickness of heat-insulation layer and working lining, ensure that the skin temperature of holding furnace is below 60 DEG C of safe temperatures.
