Specific embodiment
By the technology contents that the present invention will be described in detail, construction feature, reached purpose and efficacy, hereby enumerates embodiment below
And attached drawing is cooperated to be explained in detail.
In the description of the present invention, it is to be understood that, term " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of description of the present invention and simplification of the description, rather than the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as protecting the present invention
The limitation of range.
The present invention provides the vacuum degassing device before a kind of casting, including cabinet 1, the left and right sides difference of the cabinet 1
Equipped with import 2 and outlet 3, the import 2 and outlet 3 are equipped with valve, and the top of the cabinet 1, which is connected with, extends into cabinet 1
Vacuum line 4, the vacuum line 4 is connected with vacuum pump, is equipped with divider wall 5 in the cabinet 1 along the vertical direction, it is described every
From being equipped with the gap flowed through for melt between wall 5 and the inner top surface of cabinet 1, the divider wall 5 leans in the space in cabinet 1 every being divided into
The top surface inclination of the right chamber 7 of the left chamber 6 of nearly import 2 and close outlet 3, the divider wall 5 is arranged and close to left chamber 6
Side is higher than the other side, and the divider wall 5 is H close to the difference in height of 6 side of left chamber and the import 2, and the divider wall 5 leans on
The difference in height of nearly 7 side of right chamber and the outlet 3 is greater than H.
By using above-mentioned technical proposal, the present invention is equipped with divider wall 5, divider wall 5 between left chamber 6 and right chamber 7
Top surface inclination setting, when vacuumizing, melt from left chamber 6 flow through inclined 5 top surface of divider wall after enter right chamber 7, flow through
It will form large area film when divider wall 5, be conducive to sufficiently contact with vacuum environment, degassing effect, and whole knot can be promoted
Structure is relatively easy, and operation and maintenance maintenance cost reduce fifty percent or more compared with prior art；
Divider wall 5 is greater than H(divider wall 5 close to 6 side of left chamber and import 2 close to the difference in height of 7 side of right chamber and outlet 3
Difference in height be H), H, the liquid in this way in right chamber 7 can be greater than with the difference in height guaranteed between liquid level in right chamber 7 and outlet 3
After position is higher than outlet 3, the valve at outlet 3 can be opened, melt is flowed out, keeps the balance of vacuum degassing device, into work
Make state；
H can also be adjusted by control vacuum degree reach control melt flow to control the captured area of 5 two sides of divider wall
Effect.
Preferably, the top surface of the divider wall 5 is additionally provided with several diversion trenches.
By using above-mentioned technical proposal, is conducive to promote stability when melt flows through divider wall 5, prevent excessive
Sinuous flow.
Preferably, the height of the import 2 is higher than the height of outlet 3.
By using above-mentioned technical proposal, the directed flow of melt under vacuum environment is advantageously ensured that, prevent adverse current.
Alternatively, the import 2 and outlet 3 are contour, the import 2 is connected with the connecting tube 8 of L shape.
By using above-mentioned technical proposal, after certain special occasions, the high settings such as import 2 and outlet 3,2 company of need of import
Adapter tube 8 in succession, to guarantee that liquid level is higher than 3 liquid levels of outlet in connecting tube 8.
Preferably, the difference in height of the upper end of the connecting tube 8 and divider wall 5 close to 6 side of left chamber is not more than H.
By using above-mentioned technical proposal, it is ensured that after installing connecting tube 8, in right chamber 7 between liquid level and outlet 3
Difference in height can be greater than H, after liquid level is higher than outlet 3 in this way in right chamber 7, can open the valve at outlet 3, make melt flow
Out, the balance for keeping vacuum degassing device, into working condition.
Preferably, the vacuum line 4 is equipped with vacuum meter.
By using above-mentioned technical proposal, vacuum meter is used to monitor in real time the vacuum degree of cabinet 1, thus accurately control stream
Speed.
Working principle of the present invention is as follows: it is first shut off the valve of outlet 3, vacuum pump is opened and negative pressure is taken out to entire cabinet 1,
Under the action of external pressure, 1 inner melt liquid level opposite outer of cabinet can be increased, molten when liquid level is slightly higher crosses divider wall 5
Body starts to flow to right chamber 7 from left chamber 6, and the negative pressure for maintaining at this time can be maintained the speed of flowing, when molten in right chamber 7
Body blocks the valve of opening outlet 3 behind outlet 3 completely, and melt continues to flow to right chamber 7 from left chamber 6 at this time, when in right chamber 7
After outer liquid level difference is greater than H, melt is begun to flow out, balance of plant, start-up operation state；
Because melt passes through the inclined top surface of divider wall 5 during flowing to right chamber 7 from left chamber 6, can be formed
Large area film reaches good degassing effect so that melt is fully contacted with vacuum environment.
In conclusion only the preferred embodiments of the invention, is not limited the scope of protection of the present invention with this, it is all according to the present invention
Equivalent changes and modifications made by the scope of the patents and description are all within the scope of the invention patent covers.
