Technical Field

[0001] The utility model relates to the technical field of electromagnetic stirring, in particular to an electromagnetic stirring device for a vacuum furnace. Background Art

[0002] A vacuum furnace uses a vacuum system to discharge part of the material in the furnace cavity, thereby achieving a vacuum state in the furnace cavity. In order to facilitate the removal of impurities in the material and ensure the purity of the material, a vacuum furnace electromagnetic stirring device is required.

[0003] According to an electromagnetic stirring device disclosed on the patent website (authorization announcement number: CN 207371455 U), "an electromagnetic stirring device is described, including: a stirring tank, a liquid inlet pipeline, a liquid discharge pipeline, an air inlet pipeline, and an air outlet pipeline penetrating the stirring tank and communicating with the interior of the stirring tank, an electromagnetic stirring motor is arranged below the stirring tank, and a stirring rod driven by the electromagnetic stirring motor to stir the liquid entering through the liquid inlet pipeline is placed at the bottom of the stirring tank. The electromagnetic stirring device of the utility model can be used for stirring liquids under high pressure or vacuum environment. Compared with the existing method of stirring by driving the stirring blades through the rotating shaft, the electromagnetic stirring device of the utility model does not require an external motor or a starting motor, thereby reducing noise and energy consumption during use; and avoids the sealing problem of the rotating shaft hole, so it is more suitable for stirring volatile liquids or volatile liquids under high pressure or vacuum conditions, and reduces the frequency of component replacement."

[0004] In view of the above description, the applicant believes that the following problems exist:

However, in actual use, as the internal materials are stirred, some materials may be thrown onto the inner wall of the stirring tank and are difficult to clean, making it impossible to use other materials, and the stirring rod cannot be taken out for cleaning. Over time, the wall thickness of the stirring rod will increase, which will deteriorate the electromagnetic induction and the stirring effect. Therefore, it is necessary to improve an electromagnetic stirring device for a vacuum furnace to solve the above problems. Utility Model Content

[0027] Example 1:

[0028] See also Figure 1-4 The utility model provides a technical solution: an electromagnetic stirring device for a vacuum furnace, comprising a base 1, a vacuum furnace body 2 and a vacuum tube 3.

[0031] Furthermore, the magnetic stirrer 616 is movably installed at the bottom of the inner wall of the vacuum furnace body 2, and the semiconductor material disk 615 is arranged on the outside of the mounting column 612. The magnetic poles of the first magnetic column 613 and the second magnetic column 614 close to the magnetic stirrer 616 are opposite, so that the position conversion of the first magnetic column 613 and the second magnetic column 614 drives the magnetic stirrer 616 to move.

[0032] Furthermore, the sealing assembly 62 includes a protrusion 621, which is fixedly mounted on the outside of the vacuum furnace body 2. A rotating rack 622 is rotatably mounted inside the protrusion 621. A mounting plate 623 is fixedly mounted on the end of the rotating rack 622 away from the protrusion 621. A sealing cover 624 is fixedly mounted on the bottom of the mounting plate 623. A sealing strip 625 is fixedly mounted on the top of the vacuum furnace body 2. A functional block A626 is fixedly mounted on the outside of the vacuum furnace body 2. A limiting groove 627 is provided at the bottom of the functional block A626.

A limiting column 6211 is fixedly mounted on the end of the spring 6210 away from the rotating ring 629, so that the sealing cover 624 is locked in position to seal the inside of the vacuum furnace body 2.

[0033] Furthermore, the limiting column 6211 is movably installed inside the rotating ring 629, the functional block B628 and the functional block A626, the limiting column 6211 is clamped inside the limiting groove 627, the end of the vacuum tube 3 away from the external equipment is fixedly installed with the sealing cover 624, and the sealing strip 625 is arranged inside the sealing cover 624, which has a better sealing effect.

[0034] Embodiment 2:

[0035] See also Figure 5 , and combined with Example 1, it is further obtained that the auxiliary positioning mechanism 7 includes a motor B71, which is fixedly installed on the left side of the base 1, and a bidirectional threaded rod 72 is fixedly installed on the output end of the motor B71. Two sliders 73 are installed on the external threads of the bidirectional threaded rod 72, and a moving frame 74 is fixedly installed on the top of the two sliders 73. An arc-shaped clamping block 75 is fixedly installed on the end of the moving frame 74 close to the vacuum furnace body 2, and a plug column 76 is fixedly installed on the inner side of the arc-shaped clamping block 75, which is inserted into the inside of the socket to further strengthen the fixation of the vacuum furnace body 2.

[0036] Furthermore, a socket is opened at the corresponding position of the vacuum furnace body 2 and the plug 76, and the plug 76 is inserted into the socket, the slider 73 is slidably installed inside the base 1, and the arc-shaped clamp 75 is set outside the vacuum furnace body 2 to clamp the vacuum furnace body 2.

[0037] When the cam 72 is in the working state, the two movable frames 74 are moved by the motor 71, and the two movable frames 74 are moved by the two arc clamping blocks 75, which are clamped on the outside of the vacuum furnace body 2 to clamp the vacuum furnace body 2. At the same time, the plug post 76 is inserted into the inside of the plug hole, which further strengthens the fixation of the vacuum furnace body 2. When the vacuum furnace body 2 is stirred, the vacuum furnace body 2 will not shake, thereby protecting the vacuum furnace body 2. The magnetic stirring bar 616 is adsorbed on the bottom of the inner wall of the vacuum furnace body 2 under the action of the first magnetic column 613 and the second magnetic column 614. The raw materials are placed in the vacuum furnace body 2, and the rotating frame 622 is rotated so that the mounting plate 623 drives the sealing cover 624 to cover the top of the vacuum furnace body 2. The limit column 6211 is pressed down to slide in the functional block B628 until the bottom of the limit column 6211 passes through the bottom of the functional block A626. At this time, the spring 6210 is compressed and the rotating frame 622 is rotated. The limit column 6211 is moved 90 degrees so that the bottom of the limit column 6211 corresponds to the position of the limit groove 627. The limit column 6211 is released, and the spring 6210 rebounds to drive the limit column 6211 to rise, so that the bottom of the limit column 6211 is clamped inside the limit groove 627, so that the sealing cover 624 is locked in position to seal the inside of the vacuum furnace body 2. At the same time, the sealing strip 625 is clamped inside the sealing cover 624, and the sealing effect is better. The external equipment is started, so that the internal gas of the vacuum furnace body 2 is extracted through the vacuum tube 3, so that the interior of the vacuum furnace body 2 is in a vacuum state. The motor A611 is started to drive the mounting column 612 to rotate, and the position of the first magnetic column 613 and the second magnetic column 614 are switched. Under the action of the semiconductor material disk 615, the magnetic stirring bar 616 is driven to move, so that the magnetic stirring bar 616 vacuum stirs the raw materials inside the vacuum furnace body 2. There is no gap between the stirring shaft, and the vacuum stirring effect is better.
