Melt transportation apparatus and melt transportation method
A melt transportation apparatus according to an embodiment of the present invention comprises: a container having an internal space in which melt can be accommodated and an opening through which the melt can be input/output; a cover part which has a cover member capable of closing the opening and which is positioned at the top of the container so as to be movable forward/backward with respect to the opening; and a support part having a rotary body, which can move forward/backward with respect to the cover part at the bottom of the cover part so that the support part can be in contact with the cover part. Therefore, according to embodiments of the present invention, the opening of the container can be easily opened/closed in a limited space. In addition, when the opening is opened/closed by moving the cover part, sagging or tilting of the cover part can be prevented. Thus, the cover part can be easily moved and exposure of at least a portion of the opening to the outside can be prevented. Therefore, a decrease in the temperature of the melt inside the container can be prevented or suppressed.
1 . A molten material transport apparatus comprising:
a container having an internal space in which the molten material is accommodated and an opening through which the molten material enters and exits;
a cover unit having a cover member configured to close the opening and to be moved forward and backward with respect to the opening;
a support unit having a rotating body disposed below the cover unit and moved forward and backward with respect to the cover unit to contact the cover unit; and
a forward and backward driving unit coupled to a lower portion of the cover unit at one side of the container to move the cover unit forward and backward,
wherein the support unit is disposed between the forward and backward driving unit and the container and inclined upward so that a distance to the opening gradually decreases in a direction toward the rotating body.
2 . The molten material transport apparatus of claim 1 , wherein the support unit comprises:
a support having one end facing the cover unit, which is connected to the rotating body, and being inclined upward so that a distance to the opening gradually decreases in a direction toward the one end; and
a support driving source connected to the other end of the support to move the support forward and backward with respect to the cover unit.
3 . The molten material transport apparatus of claim 1 , further comprising a support height adjustment unit connected with the support unit to lift and lower the support unit.
4 . The molten material transport apparatus of claim 3 , further comprising:
a lifting and lowering driving unit connected to a lower portion of the forward and backward driving unit to lift and lower the forward and backward driving unit; and
first and second housings connected to both ends in a longitudinal direction of the container, respectively,
wherein the forward and backward driving unit and the lifting and lowering driving unit are disposed on an upper portion of the first housing, and
the support unit and the support height adjustment unit are disposed on a side portion of the first housing.
5 . The molten material transport apparatus of claim 4 , further comprising a power supply unit disposed on the first housing to provide power to each of the forward and backward driving unit, the lifting and lowering driving unit, the support unit, and the support height adjustment unit,
wherein the power supply unit comprises a battery.
6 . The molten material transport apparatus of claim 4 , further comprising a control unit configured to control an operation of each of the forward and backward driving unit, the lifting and lowering driving unit, the support unit, and the support height adjustment unit by wirelessly receiving a command signal input from the outside.
7 . The molten material transport apparatus of claim 4 , further comprising:
a control unit disposed on the first housing to control an operation of each of the forward and backward driving unit, the lifting and lowering driving unit, the support unit, and the support height adjustment unit; and
an operation button disposed on the first housing to transmit a command signal to the control unit.
8 . The molten material transport apparatus of claim 4 , further comprising an operation handle disposed on the first housing to control an operation of each of the forward and backward driving unit, the lifting and lowering driving unit, the support unit, and the support height adjustment unit.
9 . A method for transporting a molten material, the method comprising:
transporting a molten material transport apparatus in which the molten material is accommodated in a container; and
opening and closing an opening of the container, wherein the opening and closing of the opening comprises:
moving a cover unit forward or backward with respect to the opening; and
primarily supporting the cover unit that is moved forward or backward at a lower side of the cover unit wherein the opening and closing of the opening comprises:
lifting or lowering the cover unit after the moving of the cover unit forward or backward; and
secondarily supporting the cover unit that is lifted or lowered at the lower side of the cover unit,
wherein the primarily supporting and secondarily supporting comprise allowing a rotating body disposed below the cover unit to contact the cover unit, and
the primarily supporting comprises allowing the rotating body to rotate by a force of the cover unit that is moved forward or backward.
10 . The method of claim 9 , wherein the allowing of the rotating body to contact the cover unit comprises moving the rotating body forward or backward with respect to the cover unit, and
the moving of the rotating body forward or backward with respect to the cover unit comprises moving the rotating body forward or backward in an inclined manner so that a distance spaced apart from the opening gradually decreases as a height of the rotating body increases.
11 . The method of claim 9 , wherein the allowing of the rotating body to contact the cover unit comprises allowing the rotating body to contact an area except for an area facing the opening when a portion of the cover unit faces the opening to close the opening.
12 . The method of claim 9 , wherein each of the moving of the rotating body forward or backward, the primarily supporting and secondarily supporting, and the lifting and lowering is operated by using power.
13 . The method of claim 9 , wherein each of the moving of the rotating body forward or backward, the primarily supporting and secondarily supporting, and the lifting and lowering comprises generating a command signal through a remote controller provided separately from the molten material transport apparatus and connected wirelessly to the cover unit and the rotating body.
