Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid crucible technology, and in particular to an aluminum liquid crucible that facilitates the cleaning of scum. Background Technology

[0002] Aluminum molten metal crucibles are the core containers for melting and holding molten aluminum. They are mostly made of high-temperature resistant materials such as graphite, clay-corundum, or silicon carbide, and can withstand temperatures above 660℃ for molten aluminum. They possess characteristics of resistance to aluminum molten metal corrosion and uniform heat conduction, reducing aluminum oxidation and impurity contamination, ensuring melt purity, and are widely used in casting, aluminum alloy processing, and other fields. Impurities and scum will form on the surface of the molten aluminum in the crucible, which need to be removed to avoid affecting the quality of the molten aluminum.

[0003] The aluminum molten crucible with a surface slag removal structure is disclosed in CN223064339U. In this application, the aluminum molten crucible with a surface slag removal structure includes a base plate. Multiple rectangular support plates are fixedly connected to the upper end of the base plate. A mounting plate is fixedly connected to the upper end of each rectangular support plate. An annular plate is provided at the lower end of the mounting plate, and a telescopic rod is slidably connected inside the annular plate.

[0004] The above-mentioned device achieves a detachable design through the threaded connection structure of the scum adhesion disc, but it has the following shortcomings in actual use: when the scum adhesion disc adsorbs scum, its overall weight increases, which makes it more difficult for workers to disassemble the threaded disc. In addition, during the threaded disassembly process, the attached scum is easily detached by the rotational force, which in turn has an adverse effect on the working environment. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing scum adsorption structure uses a threaded connection, which makes disassembly difficult due to the increased weight after adsorbing scum, and the scum is easily dislodged by rotational force during the threaded disassembly process, thus polluting the working environment. Therefore, this invention proposes an aluminum liquid crucible that facilitates scum cleaning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An aluminum molten crucible for easy scum cleaning includes a support platform and a support frame. An aluminum molten crucible body is mounted on the upper surface of the support platform, and an aluminum molten crucible cover is mounted on the outer surface of the aluminum molten crucible body. A scum adsorption plate is positioned directly above the aluminum molten crucible body. A steering mechanism is positioned below the support frame. An electric push rod is installed inside the support frame, and an insertion block is installed at the bottom end of the electric push rod. A conversion connecting platform is mounted on the upper surface of the scum adsorption plate, and an installation ring is mounted on the upper surface of the conversion connecting platform. A carrier block is fixedly connected to the inner wall of the installation ring, and two limiting mechanisms are provided inside the carrier block.

[0008] Preferably, the steering mechanism includes a motor housing, inside which a drive motor is installed, and the output end of the drive motor is fixedly connected to a platform, the top of which is fixedly connected to a support frame.

[0009] Preferably, the inner wall of the motor housing is provided with a set of ventilation holes.

[0010] Preferably, the carrier block has an insertion groove inside, and the inner wall of the insertion groove is slidably connected to the insertion block.

[0011] Preferably, the limiting mechanism includes a tongue plate and a connecting groove. The connecting groove is laterally opened inside the insertion block and the carrier block. The outer surface of the tongue plate is slidably connected to the connecting groove. The bottom edges on the left and right sides of the insertion block are provided with arc-shaped chamfers.

[0012] Preferably, a pull rod is fixedly connected to the outer surface of the tongue plate, and the outer surface of the pull rod is slidably connected to the carrier block.

[0013] Preferably, a spring is fitted on the outer surface of the pull rod, and the two ends of the spring are fixedly connected to the load block and the pull rod.

[0014] Compared with the prior art, this utility model provides an aluminum molten crucible that facilitates slag cleaning, and has the following beneficial effects:

[0015] 1. This utility model replaces the threaded connection by using a limiting mechanism in conjunction with the insertion block and the carrier block. After the scum adsorption plate adsorbs the scum, pulling the lever can release the limiting mechanism, reducing the difficulty of disassembly. Moreover, there is no rotation during the loading and unloading process, which reduces the scum falling off and solves the problems of laborious operation and impact on the factory environment of existing devices.

[0016] 2. This utility model uses a steering mechanism that drives the platform and support frame to rotate via a drive motor, combined with an electric push rod to drive the insertion block to rise and fall. This allows for flexible adjustment of the horizontal position and height of the scum adsorption plate, achieving precise alignment with the aluminum liquid crucible body and improving the ease of operation for scum cleaning.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 An aluminum liquid crucible that facilitates slag cleaning includes a support platform 1 and a support frame 8. An aluminum liquid crucible body 2 is mounted on the upper surface of the support platform 1, and an aluminum liquid crucible cover 3 is mounted on the outer surface of the aluminum liquid crucible body 2. The support platform 1 provides stable support for the overall structure, and the aluminum liquid crucible cover 3 is designed to prevent external impurities from entering the aluminum liquid crucible body 2 as needed during aluminum molten metal melting or settling.

[0025] A slag adsorption plate 20 is set directly above the aluminum liquid crucible body 2. An electric push rod 9 is installed inside the support frame 8. An insertion block 10 is installed at the bottom of the electric push rod 9. The electric push rod 9 can adjust the lifting stroke of the slag adsorption plate 20 to adapt to different aluminum liquid levels.

[0026] A conversion connection platform 19 is installed on the upper surface of the scum adsorption plate 20. An installation ring 18 is installed on the upper surface of the conversion connection platform 19. A carrier block 11 is fixedly connected to the inner wall of the installation ring 18. Two limiting mechanisms are provided inside the carrier block 11. The conversion connection platform 19 cooperates with the installation ring 18 to facilitate the assembly of the scum adsorption plate 20.

[0027] The inner wall of the carrier block 11 is provided with an insertion groove 13. The inner wall of the insertion groove 13 is slidably connected to the insertion block 10. The insertion groove 13 limits the movement trajectory of the insertion block 10 and ensures the coaxiality of the connection structure.

[0028] The limiting mechanism includes a tongue plate 16 and a connecting groove 12. The connecting groove 12 is laterally opened inside the insertion block 10 and the carrier block 11. The outer surface of the tongue plate 16 is slidably connected to the connecting groove 12. The connecting groove 12 provides a sliding path for the tongue plate 16 to ensure that the limiting action is accurate and in place. The lengths of the edges of the connecting grooves 12 opened in the insertion block 10 and the carrier block 11 are exactly the same.

[0029] The bottom edges of the left and right sides of the insertion block 10 are provided with arc-shaped chamfers 14. The arc-shaped chamfers 14 reduce the frictional resistance during insertion, making it easier for the insertion block 10 to quickly connect with the carrier block 11. In addition, the arc-shaped chamfers 14 can push the tongue plate 16 to move.

[0030] A pull rod 15 is fixedly connected to the outer surface of the tongue plate 16. The outer surface of the pull rod 15 is slidably connected to the carrier block 11. A spring 17 is sleeved on the outer surface of the pull rod 15. The two ends of the spring 17 are fixedly connected to the carrier block 11 and the pull rod 15. Figure 4 In the natural state, when the carrier block 11 is connected to the insertion block 10, the arc chamfer 14 pushes the tongue plate 16 to move, causing the spring 17 to stretch. When the two connecting slots 12 are aligned, the spring 17 elastically resets, allowing the tongue plate 16 to be re-inserted into the connecting slot 12 opened in the insertion block 10 to achieve the limit.

[0031] A steering mechanism is provided below the support frame 8. The steering mechanism includes a motor box 4, and a drive motor 6 is installed inside the motor box 4. The drive motor 6 provides power for the steering action, realizes the horizontal position adjustment of the scum adsorption plate 20, and avoids interference with the flip-top lid 3 of the aluminum liquid crucible.

[0032] The output end of the drive motor 6 is fixedly connected to the platform 7, and the top of the platform 7 is fixedly connected to the support frame 8. A set of ventilation holes 5 are opened on the inner side wall of the motor box 4. The ventilation holes 5 promote air circulation and prevent the drive motor 6 from being affected by heat accumulation.

[0033] Working principle: When it is necessary to clean the scum on the surface of molten aluminum, the drive motor 6 is started and powered on. Its output end drives the platform 7 to rotate, which in turn causes the support frame 8, which is fixedly connected to the platform 7, to rotate synchronously. This moves the scum adsorption plate 20 to directly above the molten aluminum crucible body 2. The electric push rod 9 inside the support frame 8 is activated, and its piston rod extends downward, causing the insertion block 10, the platform block 11, and the scum adsorption plate 20 to descend as a whole. When the scum adsorption plate 20 contacts the scum on the surface of the molten aluminum, it uses its surface properties to adsorb the scum. Subsequently, the piston rod of the electric push rod 9 retracts, causing the scum adsorption plate 20 to rise to the height above the molten aluminum crucible body 2.

[0034] After the scum adsorption is complete, the drive motor 6 starts running again, driving the support frame 8 to rotate via the platform 7, moving the scum adsorption plate 20 with adsorbed scum to the designated cleaning platform. The operator pulls the pull rod 15 outward, causing the tongue plate 16 to slide along the connecting groove 12 and stretch the spring 17, so that the tongue plate 16 completely retracts from the insertion block 10, releasing the lock on the insertion block 10. At this time, the scum adsorption plate 20 can be separated from the insertion block 10 along with the conversion connecting platform 19, the mounting ring 18, and the platform 11, facilitating quick removal of the scum adsorption plate 20 for cleaning.

[0035] After the scum is cleaned, the insertion slot 13 of the carrier block 11 is aligned with the insertion block 10 and inserted. During the insertion process, the arc-shaped chamfer 14 guides the insertion block 10 to smoothly enter the insertion slot 13. During the process, the arc-shaped chamfer 14 squeezes the tongue plate 16 to move, and the spring 17 is compressed. When the connecting slot 12 opened in the insertion block 10 is parallel and corresponds to the tongue plate 16, the spring 17 returns to its deformation and pushes the tongue plate 16 to re-insert into the connecting slot 12 in the insertion block 10, thus completing the installation and fixing of the scum adsorption plate 20.
