Technical Field

[0001] The invention relates to the technical field of vacuum melting, and in particular to a vacuum melting device. Background Art

[0002] With the continuous development of materials science, the requirements for material processing will become higher and higher. The vacuum melting furnace can process metals with higher purity or other more difficult to melt metals in an oxygen-free or vacuum state.

[0003] However, under the existing technology, during the smelting process, the melting pot needs to be placed in a vacuum furnace. After the smelting is completed, the melting pot needs to be manually taken out from the opening on the upper side of the furnace using pliers. During the taking-out process, the melting pot is prone to spillage due to its heavy weight and liquid inside, causing production accidents. In addition, the existing vacuum melting equipment does not have the ability to filter the metal solution, and a large amount of impurities will remain in the metal solution, making it impossible to improve the purity of the metal solution.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0027] Under the existing technology, a melting pot is placed inside the furnace. The metal material in the melting pot is liquid after being melted. If the melting pot is manually clamped out with pliers, the shaking of the hand will be transmitted to the melting pot during the movement, causing the internal metal liquid to overturn, thereby increasing the processing risk.

[0028] In order to solve the above problems, Figures 1 to 6 As shown, the present invention provides a vacuum melting equipment, which includes a support cabinet 1, a furnace 2 is installed on the support cabinet 1, a control box 3 is installed on one side of the support cabinet 1, a vacuum pump 4 is installed inside the control box 3, the vacuum pump 4 is connected to the inside of the furnace 2 through a pump pipe 401, the air inside the furnace 2 is extracted to prevent the metal from being oxidized during the melting process, a motor 5 is installed at the bottom of the furnace 2, the motor 5 drives a screw 501 to rotate through a gear assembly, the axis of the screw 501 is parallel to the height direction of the furnace 2, a sleeve frame 502 is installed on the screw 501, the sleeve frame 502 is meshed with the screw 501 through a thread, when the screw 501 rotates, the sleeve frame 502 will move along the axis of the screw 501, the sleeve frame 502 moves along the axis of the screw 501, and a melting pot 7 is placed on the sleeve frame 502.

[0029] Before melting, the solid metal is first placed in the melting pot 7, and then the melting pot 7 is placed on the sleeve frame 502, and the sleeve frame 502 is clamped on the outer wall of the melting pot 7. Then the motor 5 is started, and the sleeve frame 502 is driven to move downward by the self-rotation of the screw 501, so that the melting pot 7 is placed in the heating coil at the bottom, and the heating coil heats and melts the metal inside the melting pot 7. After the melting is completed, the screw 501 rotates in the opposite direction, and the sleeve frame 502 will move upward and return to the furnace mouth of the melting furnace 2, thereby reducing the distance required for manual clamping with pliers, avoiding burns, and improving the safety of processing.

[0030] A first bevel gear 506 is installed on the motor 5, and the rotation axis of the first bevel gear 506 is perpendicular to the screw 501. The first bevel gear 506 meshes with the second bevel gear 503. The second bevel gear 503 is installed at one end of the rotating rod 504. The other end of the rotating rod 504 is installed with a third bevel gear 505, and the third bevel gear 505 meshes with the bottom of the screw 501.

[0031] The rotational power of the screw 501 of the present invention is provided by the motor 5, which drives the screw 501 to rotate through the first bevel gear 506, the second bevel gear 503, the rotating rod 504 and the third bevel gear 505 in sequence. The bevel gear connection can leave enough space for the melting pot 7 and the heating coil inside the furnace 2.

[0032] A high frequency machine is installed in the support cabinet 1 of the present invention, and a heating coil is installed at the bottom of the melting furnace 2. The high frequency machine is electrically connected to the heating coil, and the heating coil is U-shaped. The melting pot 7 is placed inside the heating coil, and the melting pot 7 is efficiently heated so that the metal in the melting pot 7 can be melted quickly. At the same time, a control panel is arranged on the support cabinet 1, and the control panel is electrically connected to the high frequency machine. The control panel can control the start and stop of the high frequency machine. A revolving door is installed on the outside of the support cabinet 1. After the revolving door is opened, the high frequency machine and other components inside can be directly repaired. At the same time, the control panel is installed on the revolving door, which is also convenient for checking the connection lines.

[0033] A sealing cover 201 is installed on the upper side of the furnace 2, and a rotating device 6 is installed on the upper side of the sealing cover 201. A motor 601 is installed in the rotating device 6. The output end of the motor 601 is connected to a rotating disk 602. An eccentric rod 603 is installed on the lower side of the rotating disk 602. The lower end of the eccentric rod 603 extends into the melting pot 7. A stirring part is installed at the bottom end of the eccentric rod 603. During the metal melting process, the eccentric rod 603 extends into the metal liquid for stirring to maintain the uniformity of the metal liquid. The sealing cover 201 is rotatably installed on the top of the furnace 2 through a hinge, which is convenient for workers to open and close.

[0034] A pressure gauge 203 is installed on the upper side of the sealing cover 201, and the pressure gauge 203 is connected to the detection device 202. The detection device 202 is penetrated on the upper side of the furnace 2, and the detection device 202 extends into the furnace 2, so that the internal pressure of the furnace 2 can be detected by the detection device 202 during the operation of the furnace 2, and then the pressure gauge 203 can display the pressure inside the furnace 2, and the status of the furnace 2 is monitored in time. The detection device 202 and the pressure gauge 203 used in the present invention are both prior arts, and the pressure gauge 203 detecting the pressure inside the furnace 2 through the detection device 202 is a conventional technical means, which will not be elaborated here.

[0035] A filter screen 701 is inserted on the inner wall of one side of the top of the melting pot 7. When pouring the molten metal, the molten metal is poured from the side of the filter screen 701 so that the impurities in the molten metal can be filtered by the filter screen 701. The purity of the molten metal in the melting pot 7 is improved.

[0036] A raised portion is formed on the outer side of the top of the melting pot 7, and an installation cavity is formed in the raised portion. A connecting plate 702 is rotatably installed in the installation cavity, and a movable rod 703 is rotatably installed at one end of the connecting plate 702. The other end of the connecting plate 702 is crimped on the upper side of the filter screen 701. A spring 704 is fixed to the bottom of the installation cavity, and the movable rod 703 is connected to the spring 704.

[0037] The spring 704 is installed in the raised part. When the movable rod 703 is pulled out to the lower side, the spring 704 is compressed, the connecting rod rotates, and the connecting rod is separated from the filter 701, so that the staff can pull out the filter 701 and replace the filter 701. If the movable rod 703 is released, the spring 704 returns to its original state, pushing the movable rod 703 back into the installation cavity, and the rotating rod rotates so that the rotating rod is pressed onto the filter 701.
