Device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this is practical
The limitation of novel protected range.
The utility model provides the vacuum degassing device before a kind of casting, including cabinet 1, the left and right sides of the cabinet 1
It is respectively equipped with import 2 and outlet 3, the import 2 and outlet 3 are equipped with valve, and the top of the cabinet 1 is connected with extension cartonning
The vacuum line 4 of body 1, the vacuum line 4 are connected with vacuum pump, are equipped with divider wall 5, institute along the vertical direction in the cabinet 1
State and be equipped with the gap flowed through for melt between divider wall 5 and the inner top surface of cabinet 1, the divider wall 5 by the space in cabinet 1 every point
For the right chamber 7 close to the left chamber 6 of import 2 and close to outlet 3, the top surface inclination setting of the divider wall 5 and close to left chamber
The side of room 6 is higher than the other side, and the divider wall 5 is H, the isolation close to the difference in height of 6 side of left chamber and the import 2
Difference in height of the wall 5 close to 7 side of right chamber and the outlet 3 is greater than H.
By using above-mentioned technical proposal, the utility model is equipped with divider wall 5, isolation between left chamber 6 and right chamber 7
The top surface inclination of wall 5 is arranged, and when vacuumizing, melt enters right chamber 7, stream after flowing through inclined 5 top surface of divider wall from left chamber 6
It will form large area film when divider wall 5, be conducive to sufficiently contact with vacuum environment, degassing effect can be promoted, and whole
Structure is relatively easy, and operation and maintenance maintenance cost reduce fifty percent or more compared with prior art；
Divider wall 5 close to 7 side of right chamber and outlet 3 difference in height be greater than H(divider wall 5 close to 6 side of left chamber with into
The difference in height of mouth 2 is H), to guarantee that the difference in height in right chamber 7 between liquid level and outlet 3 can be greater than H, in this way in right chamber 7
After liquid level is higher than outlet 3, the valve at outlet 3 can be opened, melt is flowed out, keeps the balance of vacuum degassing device, entered
Working condition；
H can also be adjusted by control vacuum degree reach control melt to control the captured area of 5 two sides of divider wall
The effect of flow velocity.
