The degassing component is fixedly installed on the furnace and cannot be removed from the furnace, so a single degassing component can only degas the aluminum liquid in a single furnace. There are generally multiple furnaces in an aluminum product factory, and accordingly, multiple degassing components need to be equipped, which is costly. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an aluminum liquid degassing device, wherein a single degassing component of the device can degas aluminum liquids in multiple melting furnaces.

[0004] The inventor has tried to make the following improvements privately: design a dedicated mobile electric lifting device for the degassing component, the degassing component is fixedly mounted on the electric lifting device, the operator operates the electric lifting device to lift the degassing device and transfer it to the furnace for degassing, after the degassing is completed, the operator operates the electric lifting device again to lift the degassing device again and transfer it to another furnace for degassing, so as to achieve the degassing of aluminum liquid in multiple furnaces with a single degassing component. After practice, the inventor found that since the degassing component is fixed together with the electric lifting device, when the degassing component is degassing on the furnace, the electric lifting component needs to stay near the furnace, the temperature near the furnace is high, and the electric lifting component is prone to failure when it is in a high temperature environment for a long time. The inventor continued to make improvements, canceled the dedicated mobile electric lifting device, and changed it to open a fork groove on the degassing component, and then used a forklift to transfer the degassing component. The forklift is inserted into the fork groove to lift the degassing component first and then transfer the degassing component. After the transfer is completed, it does not need to stay near the furnace, and can first exit the fork groove and then move to other places for operation.

[0005] In order to solve the above technical problems, the utility model provides an aluminum liquid degassing device, including a furnace for accommodating aluminum liquid, a degassing component is provided on the furnace, the degassing component has a degassing rod extending into the furnace for degassing the aluminum liquid, the degassing component is clamped together with the furnace up and down, and a fork groove is provided on it. The device includes a forklift that can be inserted into the fork groove to lift the degassing component and remove it from the furnace, and also includes a support frame for supporting an idle degassing component, a accommodating groove is provided on the inner side of the support frame to accommodate the degassing rod of the degassing component, and a receiving tray is placed at the bottom of the accommodating groove to receive the aluminum liquid dripping from the degassing rod.

[0018] The present invention is further described in detail below in conjunction with specific implementation methods.

[0019] Aluminum liquid degassing device Figure 1 , including a degassing assembly 2 and a support frame 3. The support frame 3 is cylindrical and has an upward receiving groove 31 on its inner side. The degassing assembly 2 is usually in an idle state, placed on the support frame 3 and supported by the support frame 3. The degassing assembly 2 has a degassing rod 21 extending into the receiving groove 31, and the degassing rod 21 is aligned with the center portion 312 of the bottom wall 311 of the receiving groove 31. The degassing assembly 2 has two left and right fork grooves 22. The aluminum liquid degassing device includes a forklift 4, see Figure 2 , the forklift 4 can be inserted into the fork slot 22 to lift the degassing assembly 2 and remove it from the support frame 3. Figure 3 The aluminum liquid degassing device includes a furnace 1, and the top edge of the furnace 1 is provided with two pairs of left and right slots 15. Correspondingly, the degassing component 2 extends downward with two pairs of left and right blocks 25 (only three blocks are shown in the figure due to the viewing angle), as shown in FIG. Figure 1 The left and right pairs of blocks 25 are aligned with the outer peripheral side of the support frame 3.

[0020] See Figure 3 When the aluminum liquid needs to be degassed, the operator first allows the aluminum liquid to flow into the melting furnace 1, uses the melting furnace 1 to contain the aluminum liquid, and then operates the forklift 4 to perform the following actions: Figure 2 , first insert the fork groove 22 of the degassing assembly 2, then lift the degassing assembly 2 until the degassing rod 21 of the degassing assembly 2 leaves the receiving groove 31 of the support frame 3, and then transfer the degassing assembly 2 from the support frame 3 to the top of the furnace 1, see Figure 3 , align the two pairs of blocks 25 of the degassing component 2 with the two pairs of slots 15 of the furnace 1, and then slowly lower the degassing component 2, in this way, place the degassing component 2 on the top edge of the furnace 1. In the process of the forklift 4 lowering the degassing component 2: the degassing rod 21 of the degassing component 2 extends into the furnace 1; the two pairs of blocks 25 of the degassing component 2 are inserted into the two pairs of slots 15 of the furnace 1, and the degassing component 2 and the furnace 1 are connected together in this way. The degassing component 2 is provided with a driving motor 26 to drive and connect the degassing rod 21, and is also provided with a charging unit (not shown in the figure). The driving motor 26 and the charging unit are both existing technologies. The operator starts the driving motor 26 to drive the degassing rod 21 to rotate and stir the aluminum liquid in the furnace 1, and starts the charging unit to charge nitrogen into the furnace 1 to remove the hydrogen in the aluminum liquid. In this way, the degassing component 2 degases the aluminum liquid. See Figure 4 During the degassing process, the forklift 4 does not need to stay near the furnace 1. The operator operates the forklift 4 to first exit the fork slot 22 and then move to other places to perform operations. Figure 3, the operator operates the forklift 4 to insert into the fork slot 22 of the degassing assembly 2, lift the degassing assembly 2 and remove the degassing assembly 2 from the furnace 1. If there is another furnace 1 that needs to be degassed, the operator operates the forklift 4 to move the degassing assembly 2 to the other furnace 1, and use the degassing assembly 2 to degas the aluminum liquid in the other furnace 1. In this way, a single degassing assembly 2 is used to degas the aluminum liquid in multiple furnaces 1. After completing the transfer, the forklift 4 does not need to stay near the furnace 1, but can exit the fork slot 22 first and then move to other places to operate. If there is no furnace 1 that needs to be degassed, see Figure 2 , then the operator operates the forklift 4 to transfer the idle degassing component 2 to the top of the support frame 3 and then slowly puts down the degassing component 2, uses the support frame 3 to support the idle degassing component 2 and uses the receiving groove 31 of the support frame 3 to accommodate the degassing rod 21 of the degassing component 2. In this process: the operator uses the left and right pairs of blocks 25 of the degassing component 2 as positioning blocks, and moves the forklift 4 to align the left and right pairs of blocks 25 of the degassing component 2 with the outer peripheral sides of the support frame 3 respectively. In this state, the degassing rod 21 of the degassing component 2 extends into the receiving groove 31 of the support frame 3 and is aligned with the center portion 312 of the bottom wall 311 of the receiving groove 3, as shown in FIG. Figure 1 .

[0021] See Figure 1 and Figure 5 An operation port 36 is provided on the side wall of the receiving groove 31, and a placement groove 313 is provided at the center portion 312 of the bottom wall 311 of the receiving groove 31. A receiving plate 314 is placed at the placement groove 313, and the bottom of the receiving plate 314 is embedded in the placement groove 313, and is upwardly aligned with the degassing rod 21 of the degassing component 2. After degassing, the idle degassing component 2 has residual aluminum liquid on its degassing rod 21. When it is placed on the support frame 3, the residual aluminum liquid on the degassing rod 21 drips down and falls on the receiving plate 314 at the bottom 311 of the receiving groove 31, and is received by the receiving plate 314. After the operator waits for the aluminum liquid on the degassing rod 21 and the receiving tray 314 to solidify into aluminum blocks, the operator uses a tool to extend from the operating port 36 into the receiving tank 31 to knock off the solidified aluminum blocks on the degassing rod 21, allowing these aluminum blocks to fall down onto the receiving tray 314, and then takes out the receiving tray 314, recycles the aluminum blocks on the receiving tray 314, and then replaces the receiving tray 314 on the bottom wall 311 of the receiving tank 31. Since a placement groove 313 is provided at the center portion 312 of the bottom wall 311 of the receiving tank 31, when placing the receiving tray 314, the operator only needs to align the bottom of the receiving tray 314 and embed it into the placement groove 313, and then the receiving tray 314 can be placed on the center portion 312 of the bottom wall 311 of the receiving tank 31. The operation is convenient and there is no need to manually adjust the position of the receiving tray 314. Figure 6 A frame shifting slot 30 is provided at the bottom of the support frame 3. The operator operates the forklift 4 to insert into the frame shifting slot 30 of the support frame 3 and then lifts the support frame 3, so as to move the support frame 3 to a suitable position.

[0022] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
