Description
Technical field
The utility model belongs to vacuum melting technology field, is related to a kind of secondary charging device of vacuum melting furnace.
Background technology
Vacuum melting furnace secondary charging equipment is under vacuum or protective atmosphere, by induction heating mode by metal or conjunction
The alloy material matched or secondary material, are then hung in above crucible by gold fusing in advance, and lower section earthenware is fallen into when charging is needed
In crucible.Passage is transferred to above crucible by also useful passage charging, the used time, and secondary material is fallen into crucible along conduit.It is existing
The second batch filing provision of vacuum induction melting furnace mainly has；Rotary 4 valve or 6 valve dividing plate feeding devices and straight-through upper charging
Device.Rotating barrier feeding chamber can only add than larger particulate material, and fault rate is more, and material can mix rotating barrier sometimes, cause
Turn motionless, and material can cause molten metal splashing when falling into crucible, feeding chamber can also be left sometimes；Passage be able to will also turn
It is dynamic, vacuum chamber space is so increased, passage will be shifted and many dynamic sealings, add leak source probability.Straight-through upper charging dress
It is to put a small bin again above vacuum chamber to put, material is hung over above crucible in advance, it is necessary to when fall into again in crucible, it is this to have
Be use and crucible in fusing metal liquid same material lametta lift, be a little above hang a funnel, here lid
Tied with fine rule, the used time drops to funnel above fusing metal liquid, and after line blows, the material in funnel falls into crucible
Complete charging.It is described above all to achieve the goal in a manual manner, and repeatedly charging is restricted, and increases vacuum chamber empty
Between, reliability is not strong, leak source increase, destroys vacuum, and fault rate is high, so directly affects the quality of product, then adds enterprise
The cost of industry.
The content of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide the two of a kind of vacuum melting furnace
Secondary feeding device.
In order to realize foregoing invention purpose, the utility model uses technical scheme as described below：
A kind of secondary charging device of vacuum melting furnace, including vacuum melting furnace melting bin, charging bin, charging
Storehouse, vacuum valve, vavuum pump and elevating mechanism, the melting bin upper port are provided with vacuum valve, and the lower port of charging bin connects
It is connected on vacuum valve, feeding chamber is provided with feeding chamber room, the lower end of the elevating mechanism is stretched into feeding chamber room and with adding
Feed bin is fixedly connected, and the vavuum pump is used to vacuumize feeding chamber chamber interior by the tracheae set thereon.
Further, the elevating mechanism includes drive gear and rack, rack and drive gear by tooth engaged transmission,
The lower end of rack is stretched into feeding chamber room and is fixedly connected with feeding chamber.
Due to using above-mentioned technical proposal, the utility model has following superiority：
The utility model is novel, reasonable in design, can not destroy the vacuum of main molten refining bin, realize continuous two
Secondary charging operation, easy to operate, safety, can effectively shorten the charging activity duration.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1st, feed bin；2nd, melting bin；3rd, feeding chamber；4th, vacuum valve；5th, elevating mechanism；6th, vavuum pump.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the technical solution of the utility model.
As shown in figure 1, a kind of secondary charging device of vacuum melting furnace, includes melting bin 2, the charging of vacuum melting furnace
Bin 1, feeding chamber 3, vacuum valve 4, vavuum pump 6 and elevating mechanism 5, the upper port of melting bin 2 are provided with vacuum valve 4, plus
The lower port of feed bin room 1 is connected on vacuum valve 4, and feeding chamber 3, the lower end of the elevating mechanism 5 are provided with charging bin 1
Stretch into charging bin 1 and be fixedly connected with feeding chamber 3, the vavuum pump 6 is used for feeding chamber by the tracheae set thereon
Vacuumized inside room 1.
The elevating mechanism 5 includes drive gear and rack, and rack and drive gear are by tooth engaged transmission, under rack
End is stretched into feeding chamber room and is fixedly connected with feeding chamber.
Specific charging process of the present utility model is：
1st, the material needed for first feeding chamber is added；
2nd, charging bin is attached on vacuum valve again；
3rd, vavuum pump is opened to being vacuumized in feeding chamber room, is evacuated to identical with melting bin vacuum or more low vacuum
Degree；
4th, it is filled with protective gas into feeding chamber room again；
5th, vacuum valve is opened when charging is needed afterwards；
6th, feeding chamber is down to above the crucible in melting bin by elevating mechanism, and then feeding chamber can be automatically opened up, material
Fall into crucible；
7th, elevating mechanism is again by feeding chamber lifting to charging bin position；
8th, vacuum valve is closed, the operation that once feeds is completed.
If working continuously, the vent valve for opening charging bin carries out broken sky, and then will feed bin call away to, will feed
Storehouse, which falls to be again loaded into after material, is back to charging bin, and repeat step 2 to 8 can be achieved repeatedly to feed or work continuously.
The utility model is to add material under not destroying vacuum state into the crucible of vacuum melting room, molten in vacuum
It is on sweetening process, very high to the vacuum level requirements of working chamber, it is ensured that vacuum will not influence the quality of product, in melting vacuum
Secondary charging is realized in room in the case of not breaking sky, is substantially shorter duty cycle, improves production efficiency, and reduction enterprise is produced into
This.
