Abstract
The invention provides a double-chamber continuous-pressurization molten aluminum electrical heating and holding furnace which is formed by integrally welding iron plates, wherein a furnace body consists of a working chamber (1) and a standing chamber (4); the working chamber (1) and the standing chamber (4) are connected by virtue of a stopper (12) and a stopper base (11). The double-chamber continuous-pressurization molten aluminum electrical heating and holding furnace is characterized in that one end of the stopper (12) is connected with a cylinder I (9) and a cylinder II (10); the cylinder I (9) drives the stopper (12) to move up and down; the cylinder II (10) drives the stopper (12) to rotate for 90 degrees, so that the stopper base (11) is blocked by the stopper (12), and an adhesion surface is completely sealed. In a process of supplying molten aluminum to a low-pressure casting machine by the working chamber, a gap at the communication part of the two chambers is always blocked, so that an operation of adding molten aluminum into the standing chamber is not influenced; before the gap is reopened to add molten aluminum into the working chamber, the time for standing the molten aluminum in the standing chamber is sufficient, so that the purity of molten aluminum flowing into the working chamber is ensured.
Description
Technical field
The present invention relates to two rooms continuous pressure aluminium liquid electrical heating holding furnace used when aluminium liquid produced by a kind of air injection machine.
Background technology
To air injection machine matching used aluminium liquid electrical heating holding furnace, shell is formed by iron plate integral solder, and attach heat-insulation layer and working lining successively from outside to inside, heat-insulation layer is high temperature insulating material, and working lining is containing Al
2o
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 problem, the object of the present invention is to provide a kind of two rooms continuous pressure aluminium liquid electrical heating holding furnace, that furnace chamber is divided into operating room and rest chamber, operating room provides aluminium liquid to use to air injection machine, rest chamber stores a certain amount of aluminium liquid and carries out leaving standstill filtration, when the aluminium liquid of operating room uses, by the breach of operating room and 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.
Technical scheme of the present invention is achieved in the following ways: two rooms continuous pressure aluminium liquid electrical heating holding furnace, formed by iron plate integral solder, be made up of operating room and rest chamber in body of heater, stalk and immersion heating tube I is provided with in described operating room, degasification rod and immersion heating tube II is provided with in moist closet, operating room and rest chamber be coupled through stopper and stopper seat realizes, it is characterized in that: one end of described stopper is connected with cylinder I and cylinder II, cylinder I drives stopper to move up and down, cylinder II drives stopper half-twist, make stopper block stopper seat and ensure that binding face seals completely.
What described stopper stretched out the top connection of liquid level one end is cylinder I, and what be connected with stopper vertical direction is cylinder II.
An aluminium liquid liquid level sensor 3 is had, for detecting the height of aluminium liquid in described operating room.
The present invention, there is provided aluminium liquid in the process of air injection machine in operating room, between two Room, the breach of UNICOM is blocked all the time, do not affect the interpolation aluminium liquid to rest chamber, refinery by de-gassing work is carried out to the aluminium liquid in rest chamber, before reopening breach and adding aluminium liquid to operating room, has time enough to leave standstill the aluminium liquid in rest chamber, make the oxide impurity in aluminium liquid be deposited to bottom rest chamber, ensure the clarity flowing into aluminium liquid in operating room.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Known by Fig. 1, two rooms continuous pressure aluminium liquid electrical heating holding furnace, is formed by iron plate integral solder, body of heater Nei You operating room 1 and rest chamber 4, stalk 2 and immersion heating tube I 7 is provided with in described operating room 1, be provided with degasification rod 5 and immersion heating tube II 6 in moist closet 4, the breach between UNICOM two Room, drive stopper 12 clogging by cylinder I 9, ensure that air injection machine is in compression casting, the supply to rest chamber aluminium liquid can be carried out, when the supply of aluminium liquid, pressurized control is not had an impact; Stopper 12 is driven by cylinder I 9 and moves up and down, when stopper seat 11 blocked by stopper 12, in order to the binding face preventing oxide impurity to be stuck in stopper 12 and stopper seat II, stopper 12 half-twist is driven again by cylinder II 10, oxide impurity is rolled, ensures that binding face seals completely.There is an aluminium liquid liquid level sensor 3 in operating room 1, when aluminium liquid being detected, illustrating that aluminium liquid liquid level has arrived the highest spacing, need to stop adding aluminium liquid.
The course of work:
1, cylinder I 9 drives stopper 12 downward, and stopper 12 and stopper seat 11 are fitted, and block the breach between two Room;
2, cylinder II 10 drives stopper 12 to rotate, and what stopper 12 and stopper seat 11 were fitted is tighter;
3, aluminium liquid is added in rest chamber 4, and degasification rod starts nitrogen injection, removes the hydrogen in aluminium liquid;
4, the aluminium liquid in rest chamber 4 starts to leave standstill, precipitated oxides impurity;
5, cylinder I 9 drives stopper 12 upwards, and the breach that stopper 12 leaves between stopper seat 11, two Room is opened;
6, the aluminium liquid in rest chamber 4, under self gravitation effect, flow into operating room 1 by the breach between two Room;
7, aluminium liquid level detection is to aluminium liquid;
8, cylinder I 9 drives stopper 12 downward, and stopper 12 and stopper seat 11 are fitted, and block the breach between two Room;
9, cylinder II 10 drives stopper 12 to rotate, and what stopper 12 and stopper seat 11 were fitted is tighter;
10, operating room 1 is injected into compressed air, and compressing aluminium liquid is entered in the mold cavity of air injection machine by stalk.
