Specific embodiment
Technical solution of the present invention is described in detail in the following with reference to the drawings and specific embodiments, to be further understood that
The purpose of the present invention, scheme and effect, but it is not intended as the limitation of scope of the appended claims of the present invention.
As shown in Figure 1 to Figure 3, the preferred embodiment for disclosing the deslagging device of vacuum gas atomization plant of the present invention, by
Schema is it is found that the deslagging device of vacuum gas atomization plant of the present invention includes a body of rod 10 and a disk body 20.
The body of rod 10 captures portion 11 and a group connecting part 12 comprising one, which is set to this and captures the bottom end in portion 11,
In, it includes the undertaking wing 13 with connecting hole 14 that this, which captures portion 11, which convexedly stretches in the group connecting part 12, the connection
The undertaking wing 13 is run through in hole 14.
The disk body 20 be set to the body of rod 10 on, the disk body 20 include one with it is multiple except cinder hole 22 remove slag pan 21, it is described
Except slag pan 21 is set to the group connecting part 12, those except cinder hole 22 be set to being alternatively arranged should except slag pan 21 and through should except slag pan 21,
The cinder hole 22 that removes is in the from bottom to top tapered hole of size, wherein the shape of the disk body 20 is disk, which runs through
This removes the center of slag pan 21, described to remove slag pan 21, the disk body 20 around this is arranged in for the center of circle with the group connecting part 12 except cinder hole 22
Comprising multiple stirring parts 23, those stirring parts 23 are that the center of circle is circumferentially set to the bottom for removing slag pan 21 with the group connecting part 12, should
Neighbouring a little stirring parts 23 should include a barricade 24 except the edge of slag pan 21, the disk body 20, which is located on this except slag pan 21
Top and it is neighbouring should be except the edge of slag pan 21, in this present embodiment, sharp claw-like is presented in the bottom end of the stirring parts 23.
As shown in Figures 2 to 4, a preferred embodiment of the deslagging device of vacuum gas atomization plant of the present invention is disclosed, it is existing
There is one to capture device 30, it includes a shell 31, a lifters 32 and a revolving part 33 that this, which captures device 30, which is set to
The inside of the shell 31, the revolving part 33 are rotatably disposed within the bottom of the lifters 32, this is captured portion 11 and pacified by staff
Loaded on the revolving part 33,13 groups of the undertaking wing sets the revolving part 33, as shown in Figures 4 and 5, for melting operation to be carried out,
This is captured into device 30 and is installed on a vacuum gas atomization plant 40, so that the enclosure interior for capturing device 30 is connected to the vacuum
The inside of gas atomization equipment 40, so that the inside of the shell 31 is presented very as the inside of the vacuum gas atomization plant 40
Dummy status, then preparation work is completed ready, can carry out melting operation.
Among the above, as shown in Figures 5 to 7, the operation aspect of the deslagging device of vacuum gas atomization plant of the present invention is disclosed,
Staff controls the lifters 32, so that the body of rod 10 protrudes into the inside of the vacuum gas atomization plant 40, and protrudes into this
The alloy solution 50 that vacuum gas atomization plant is contained, the impurity in metal and alloy form the surface of alloy solution 50
One impurity layer 51, staff can operate the lifters 32, make the revolving part 33 that this be driven to capture portion 11 and move down, so that should
Except the bottom of slag pan 21 contacts the impurity layer 51 and should remove the impurity layer that slag pan 21 pushes by this except slag pan 21 can be continued to decline
51 can remove the top of slag pan 21 except cinder hole 22 is extruded into this by those, and concentrate on the top for removing slag pan 21, which can
To prevent this from will not flow to the top for removing slag pan 21 except the alloy solution 50 around slag pan 21, because it should remove on slag pan 21 described in
Except cinder hole 22 is in from bottom to top the tapered hole of size, the surface tension of the impurity layer 51 overcome the gravity of the impurity layer 51, make
The top for removing slag pan 21 can be stayed in without, except cinder hole 22 is toward flowing down, staff, which then operates, to be somebody's turn to do from those by obtaining the impurity layer 51
Lifters 32 rise, so that the impurity layer 51 removes the upward band of slag pan 21 by this, then achievable slagging-off operation keeps subsequent production gold
Belong to the quality of powder.
Among the above, if the case where alloy solution 50 need to unevenly stir, staff can operate the lifters 32 decline
So that those stirring parts 23 is touched metallic solution 50, and operate the revolving part 33, so that can to stir alloy molten for those stirring parts 23
Liquid 50 increases the practicability of the deslagging device of vacuum gas atomization plant of the present invention.
In conclusion the deslagging device of vacuum gas atomization plant of the present invention removes cinder hole 22 by described, slag pan 21 should be removed
It pushes so that the impurity layer 51 of alloy solution 50 is squeezed by the cinder hole 22 that removes to the top being somebody's turn to do except slag pan 21, and is removed because described
Cinder hole 22 is in from bottom to top the tapered hole of size, the surface tension of the impurity layer 51 of alloy solution 50 overcome the impurity layer 51
Gravity then should will not up be promoted from described except cinder hole 22 is toward the top for flowing down and staying in this except slag pan 21 except slag pan 21
Slagging-off operation is completed, metal powder quality is kept.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
It knows those skilled in the art and makes various corresponding changes and modifications, but these corresponding changes and change in accordance with the present invention
Shape all should fall within the scope of protection of the appended claims of the present invention.
