Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in detail:
As shown in figure 1, the distillatory insulation smelting furnace of continuous vacuum of the present utility model, lives including heat-preservation bottom, first
Dynamic insulated wall, the second moving thermal insulation wall, crucible, induction coil, containment vessel and controller switching equipment.
The first slide rail and the second slide rail being parallel to each other is provided with heat-preservation bottom.Slide rail is rail, is fixed on insulation bottom
Plate upper surface, with plane-parallel.Heat-preservation bottom is cement bottom plate, is equipped with refractory brick.
First moving thermal insulation wall has the two sides being mutually connected vertically, and forms right angle metope.Two sides the first moving thermal insulation wall bottom
End is respectively arranged with the first chute and the second chute.First chute is arranged at one end of the first moving thermal insulation wall, and the second chute sets
It is placed in the other end of the first movable wall.First chute is opened up along the length direction of a wherein face wall of the first moving thermal insulation wall, the
Two chutes are opened up along the thickness direction of another face wall of the first moving thermal insulation wall, and the length of the first chute is more than the length of the second chute
Degree.First chute is slidably connected with the first slide rail, and the second chute is slidably connected with the second slide rail.First moving thermal insulation wall can be right
Crucible heat insulation, reduces heat losses, and can provide security isolation effect to crucible.As the first moving thermal insulation wall is right angle
Wall, good stability are difficult to topple over.As the first moving thermal insulation wall can slide along the first slide rail and the second slide rail and then mobile
Crucible is left in position, and the convenient induction coil on crucible is keeped in repair.
Second movable wall is corresponding with the first movable wall.Second moving thermal insulation wall has the two sides being mutually connected vertically, and is straight
Angle metope.Two sides the second moving thermal insulation wall bottom is respectively arranged with the 3rd chute and the 4th chute, and the 3rd chute is arranged at second
One end of moving thermal insulation wall, the 4th chute are arranged at the other end of the second moving thermal insulation wall.3rd chute is along the second moving thermal insulation
The thickness direction of a wherein face wall of wall is opened up, and the 4th chute is opened along the length direction of another face wall of the second moving thermal insulation wall
If the length of the 3rd chute is less than the length of the 4th chute.3rd chute is slidably connected with the first slide rail, the 4th chute and second
Slide rail is slidably connected.Second moving thermal insulation wall can be reduced heat losses, and can provide safety to crucible to crucible heat insulation
Buffer action.As the second moving thermal insulation wall is right angle wall, good stability is difficult to topple over.As the second moving thermal insulation wall can be with
Slide along the first slide rail and the second slide rail, and then crucible is left in shift position, the convenient induction coil on crucible is keeped in repair.
First moving thermal insulation wall and the mutual split of the second moving thermal insulation wall form enclosure wall.Moving thermal insulation wall be refractory brickwork simultaneously
Painted by cement.Enclosure wall can both be separated into the first moving thermal insulation wall and the second moving thermal insulation wall, can merge formation four again
Face enclosure wall, cooling are convenient, easy to maintenance, again can be to crucible heat insulation and insulation blocking.
Crucible is arranged in the heat-preservation bottom between enclosure wall.Crucible is used for loading solid alloy and holds thawing alloy, no
Only solid alloy can be melted, and can be to melting alloy insulation.Molten metal in crucible is transported to by material pump device
In the distillation tray of vacuum distillation furnace.
Induction coil is looped around crucible lateral wall from top to bottom successively.Electromagnetic induction is produced after induction coil indirect current,
The electronics of the alloy in crucible can be driven to flow to form eddy current, and then melt alloy heat generating.And crucible is for nonmetallic,
Produce without eddy current, so will not melt.
Containment vessel is covered in outside induction coil.Containment vessel is non-metal case, such as glass, pottery, plank etc..Containment vessel can be with
Protection induction coil is without damage, e.g., the molten alloy in crucible can be prevented to be dropped on coil, and hard thing can be prevented to clash into
Induction coil etc..
Controller switching equipment electrically connects induction coil.Distribution is arranged mainly includes switch and transformator etc., for controlling the line of induction
The energization of circle and the suitable electric current of configuration.
As shown in figure 1, the lateral wall of crucible is gradually inwardly rolled tiltedly from the top to the bottom.As lateral wall inwardly rolls
Tiltedly, can further reduce motlten metal to be dropped on induction coil, and then prevent to damage induction coil, reduce short-circuit and disconnected
Electricity, improves safety and stability.
As shown in figure 1, crucible top lateral wall is surrounded with protective cover directed downwardly, protective cover bottom arranges fluted.
Stretch in groove at the top of containment vessel.Protective cover can play the protective action of similar eaves, further reduce motlten metal drippage
On induction coil, and then protect induction coil without damage.Its further groove can reduce motlten metal along protective cover to dirty
Dynamic, and then induction coil is protected, while the containment vessel of induction coil can be stretched in groove, reduce motlten metal and flow into sensing
Between coil and protection, make the motlten metal of drippage flow along containment vessel outer wall, and then protect induction coil.
As shown in figure 1, being respectively arranged with roller at the top of the first slide rail and the second slide rail.Pulley can improve the slip of slide rail
Performance, reduces the resistance that enclosure wall slides on slide rail, and then is moved easily enclosure wall, and then convenient maintenance.
As shown in figure 1, being additionally provided with hot plate between crucible bottom and heat-preservation bottom, the height of hot plate is slided higher than first
The height of rail and the height of the second slide rail.Due to having gap between enclosure wall bottom and slide rail, there is certain gas leakage, high by arranging
In the hot plate of the height of slide rail, crucible bottom is socketed in hot plate, insulation effect is further provided for crucible bottom.
