In order to preferably understand technical solution of the present invention, below by specific embodiment, and combine attached Figure is described in detail:
Referring to Fig. 1, charging system includes upper feed compartment general assembly 1, vacuum insulation on a kind of vaccum sensitive stove of the invention Valve gear 2 and electric control box.Wherein, upper feed compartment general assembly 1 is connected by hermetically sealed flange 3 with vacuum isolation valve device 2 It is logical.The discharge port of vacuum isolation valve device 2 is connected on the melting cavity 4 of vaccum sensitive stove.
Fig. 2 and Fig. 3 are please referred to, upper feed compartment general assembly 1 includes feed compartment ontology 91, motor room 92.
Charging lifting device is equipped in motor room 92, charging lifting device is by 10 groups of driving device of hook gear 13 and charging At the suspension hook of hook gear 13 is by the driving axis connection of elevator belt and reel and charging driving device 10, and feed driving device 10 drive drive shaft by hydraulic motor and retarder, and the shaft end of drive shaft is connected with an encoder 15, encoder 15 Connect with electric control box signal, to control revolving speed and stroke, rope amount is put in accurate control.The driving for the driving device 10 that feeds The telescopic sampler 19 driven by charging driving device 10 is also connected on axis, when sampler 19 is transferred When, the decentralization indoor material of melting can be sampled.It is additionally provided with thermocouple 18 in motor room, the temperature in system is carried out Monitoring.
The charging bucket 14 connecting with charging lifting device is equipped in feed compartment ontology 91, which can be in hook gear It is moved up and down under 13 drive.The front end face of feed compartment ontology is equipped with the openable feed opening entered and left for the charging bucket, adds Material mouth is closed by door-plate 11, and door-plate 11 and feed opening carry out hingedly, sealing being equipped between door-plate 11 and feed opening using hinge Circle.The quadrangle of door-plate 11 is locked using U-shaped folder 16, to guarantee the overall sealing performance of feed compartment ontology 91.On door-plate 11 Equipped with vacuum meter.The side of door-plate 11 is equipped with a shaft, and a swinging arm device 12 can be connect around what door-plate 11 rotated with shaft; When door-plate 11 is opened, which rotates in feed opening, when door-plate 11 is closed, the swinging arm device 12 rotation to institute The side for stating door-plate is resetted.The bottom of feed compartment ontology 91 offer for charging bucket 14 enter and leave discharge port, flange 3 with go out Material mouth connection.
When carrying out charging operation, confirmation vacuum isolation valve device 2 is in close state, and door-plate 11 is opened, by material to be added It is fitted into charging bucket 14, and charging bucket 14 is placed on the pallet of swinging arm device 12 (141 position).Push swinging arm device 12 Pallet is screwed in the inside of feed compartment ontology 9 by handle.Start lifting driving device 10, control hook gear 13 drops to properly Charging bucket 14 is caught on suspension hook in position.Control lifting driving device 10 lifts charging bucket 14, pushes the hand of swinging arm device 12 Handle screws out pallet to outside feed compartment ontology 9.Feed compartment door 11 is closed, and locks door-plate 11 with U-shaped folder 16.Room door to be fed After 11 lockings, vacuum pump is opened, 9 internal cavity of feed compartment ontology is evacuated to by specified range according to vacuum meter 17.
Vacuum isolation valve device 2 is the vacuum buffer chamber of system, and top passes through flange 3 and upper feed compartment general assembly 1, Bottom is equipped with the discharge port that opening and closing control is carried out by valve mechanism, which is connected to the melting cavity 4 of vaccum sensitive stove On.Vacuum isolation valve device 2 is equipped with vacuum orifice 26.
Please refer to Fig. 4.The valve mechanism of vacuum isolation valve device 2 includes valve body ontology 20, rotating hydraulic cylinder 21, compresses liquid Cylinder pressure 22, valve plate 23, valve plate swing arm 24, rotary shaft 25 and cooling water channel 27.
Wherein valve body ontology 20 is made of left and right two parts, and centre is flanged joint, rubber sealing.Valve plate 23 passes through reset Spring is connected in valve plate swing arm 24, and valve plate swing arm 24 is fixed using flat key and rotary shaft 25, and rotary shaft 25 is hydraulic by turning round Cylinder 21 drives, and rotating hydraulic cylinder 21 is connect with electric control box.Valve plate 23, which has, opens and closes 2 positions.The two sides of valve plate 23 Equipped with the compression hydraulic cylinder 22 for having position detecting element is respectively equipped with, position detecting element is connect with electric control box.
When 9 internal cavity of feed compartment ontology is in non-vacuum, valve plate 23 is compacted hydraulic cylinder 22 and is tightly pressed against valve On the sealing ring of 20 closed position discharge port of body ontology, vacuum environment in melting cavity is kept.It is finished when material to be added loads, door Plate 11 is closed, and after U-shaped folder 16 is locked, vacuum pump is opened, needed for being evacuated to 9 internal cavity of feed compartment ontology by vacuum orifice 26 The vacuum state wanted, 23 top and the bottom cavity of valve plate is all in vacuum environment at this time.Then, it is controlled by electric control box and compresses liquid Cylinder pressure 22 returns to released position, and under spring force, valve plate 23 is raised, and is separated from discharging mouth sealing ring.It turns round at this time Hydraulic cylinder 21 acts, and valve plate 23 is driven to be turned back to open position (in figure at dotted line).14 bottom turnover panel of charging bucket is unclamped, completes to add Material movement.Finally, by rotating hydraulic cylinder 21 and compressing the effect of hydraulic cylinder 22 again, it is in close state valve plate 23 again.By The discharge port that material enters melting chamber is covered in valve plate 23, the temperature at this is influenced by melting chamber, therefore in valve plate It is disposed with cooling-water duct 27 on 23, is connected to around the water route in rotary shaft 25, then is formed into a loop with external cooling water, to drive Dynamic structure is cooled down.
On a kind of vaccum sensitive stove of the invention in charging system, by being provided with dedicated isolation above melting cavity The charging mechanism of valve is saved in the case where not blowing out by working continuously so that working chamber continuously keeps vacuum state Charging, waits the time to be cooled.Shorten smelting cycle, improves utilization rate of equipment and installations.Continuous production is while increasing efficiency Increase the yield of alloy.Upper feed compartment is mainly used to ball adding shape and block-like big density material, and the most charges of single are reachable 5T;And thermometric sampling and material alloying can be carried out inside it, stable, absolutely not the phenomenon that putty, occurs, and it is small to be able to satisfy 24 When non-stop-machine production need.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention, And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above Change, modification will all be fallen within the scope of claims of the present invention.
