Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of overhaul slag storage, and more specifically relates to an overhaul slag storage device for an aluminum electrolytic cell. Background Art
[0002] Aluminum cell overhaul slag is a solid waste residue generated during regular maintenance and material replacement of aluminum cells. This residue contains highly corrosive and toxic substances, such as soluble fluorides and cyanides. Its storage can severely impact groundwater and soil. Currently, during overhaul maintenance, aluminum cell slag is typically stored in iron or plastic drums to prevent environmental damage caused by its exposure to the elements. However, traditional plastic drums are thin and lightweight, with poor impact resistance, making them susceptible to deformation and damage. Transporting the slag can easily lead to bumps and collisions, causing slag leaks. If stored in iron drums, the slag is highly corrosive. Furthermore, to prevent spillage of slag nearing capacity, traditional storage drums often leave some excess space inside the drums, reducing their storage capacity. Summary of the Invention
[0003] In order to solve the above technical problems, the utility model provides an aluminum electrolytic cell overhaul slag storage device to solve the problems of poor storage capacity of traditional aluminum electrolytic cell overhaul slag storage barrels and the barrel body being easily bumped, corroded and damaged, resulting in overhaul slag pollution and leakage.

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0022] like Figures 1-6 As shown, the utility model provides a slag storage device for overhauling an aluminum electrolytic cell, comprising a hand-held turret 2; a bidirectional threaded rod 5 is welded to the bottom end of the hand-held turret 2, and the bottom end of the bidirectional threaded rod 5 is rotatably connected to a base 4; it also includes a vertical rod 9; the bottom end of the vertical rod 9 is welded to the base 4, and the top end of the vertical rod 9 is welded to an outer barrel 3; the outer side surface of the outer barrel 3 is slidably connected to a baffle shell 6, the inner side surface of the outer barrel 3 is bonded to an inner barrel 8, the outer side surface of the outer barrel 3 is provided with a convex plate near the top position with a through hole, and the bidirectional threaded rod 5 is rotatably connected in the through hole of the convex plate of the outer barrel 3; the outer barrel 3 is welded to the center position of the upper side surface of the base 4, the top end of the outer barrel 3 is hinged to a flip cover 1, the upper side surface of the flip cover 1 is welded to a connecting rod 10, the rear end of the connecting rod 10 is hinged to a push-pull rod 11, and the bottom end of the push-pull rod 11 is hinged to a lifting frame 7.
[0023] In the disclosed embodiment, the baffle shell 6 is a cylindrical structure that penetrates from top to bottom. A convex plate is provided on the outer side surface of the baffle shell 6. A threaded through hole with a vertical penetration rate is provided at the center position of the upper side surface of the convex plate. The outer side surface of the bidirectional threaded rod 5 is engaged with the threaded through hole of the convex plate of the baffle shell 6 with positive threads. The positive threads of the bidirectional threaded rod 5 drive the convex plate of the baffle shell 6 to move upward or downward, allowing the baffle shell 6 to extend one end distance from the top of the outer barrel 3, thereby preventing the overhaul slag of the aluminum electrolytic cell from overflowing and leaking when the inner barrel 8 is filled with the slag.
[0024] In the disclosed embodiment, the outer barrel 3 is a barrel structure with an open upper side. The outer barrel 3 is made of high-strength steel. The inner barrel 8 is embedded in the inner side of the outer barrel 3 so that the outer barrel 3 wraps and protects the inner barrel 8. The outer side of the outer barrel 3 is provided with a rectangular through groove structure that passes through the front and back. The convex plate of the baffle shell 6 is inserted into the rectangular through groove of the outer barrel 3. The left side and the right side of the convex plate of the baffle shell 6 are fitted on the groove wall of the rectangular through groove of the outer barrel 3, so that the rectangular through groove of the outer barrel 3 supports the convex plate of the baffle shell 6, allowing the baffle shell 6 to move vertically and stably.
[0025] In the embodiment of the present disclosure, the lifting frame 7 is a ring structure that passes through from top to bottom. The inner diameter of the ring structure of the lifting frame 7 is the same as the outer diameter of the outer barrel 3. The outer barrel 3 is embedded in the inner side of the ring structure of the lifting frame 7. The upper side surface of the lifting frame 7 is provided with four groups of through holes. The four groups of vertical rods 9 are respectively inserted into the four groups of through holes of the lifting frame 7. The outer side surface of the lifting frame 7 is provided with two groups of convex plates. The two groups of convex plates of the lifting frame 7 are symmetrically distributed front and back. The upper side surface of the front convex plate of the lifting frame 7 is provided with a threaded through hole that passes through from top to bottom. The reverse threaded end of the outer side surface of the two-way threaded rod 5 is engaged and connected to the threaded through hole of the convex plate of the lifting frame 7. The upper side surface of the rear convex plate of the lifting frame 7 is hinged with a push-pull rod 11. During the rotation of the two-way threaded rod 5, the lifting frame 7 is driven to move vertically upward or downward along the vertical rod 9, so that the lifting frame 7 pulls the flip cover 1 welded to the connecting rod 10 through the push-pull rod 11 to perform the flip opening and closing operation of the top opening of the outer barrel 3.
[0026] In the disclosed embodiment, the inner barrel 8 is made of polyethylene plastic, and aluminum electrolytic cell overhaul slag is stored in the inner barrel 8. The good corrosion resistance of polyethylene plastic is utilized to separate the highly corrosive aluminum electrolytic cell overhaul slag from the steel outer barrel 3, thereby preventing the aluminum electrolytic cell overhaul slag from overlooking the outer barrel 3.
[0027] In the disclosed embodiment, a rubber gasket is provided on the lower side of the flip cover 1. When the flip cover 1 and the outer barrel 3 are closed, the rubber gasket of the flip cover 1 fits against the outer edge of the barrel mouth of the outer barrel 3, so that the flip cover 1 cooperates with the outer barrel 3 to seal and close the aluminum electrolytic cell overhaul slag in the inner barrel 8, thereby preventing fine aluminum electrolytic cell overhaul slag from leaking into the external environment through the closed gap between the flip cover 1 and the outer barrel 3.
[0028] The specific usage and function of this embodiment are as follows:
[0029] When the utility model is performing the slag storage work of the aluminum electrolytic cell overhaul, the hand-held rotating frame 2 is manually rotated, and the hand-held rotating frame 2 drives the bidirectional threaded rod 5 to rotate. Since the threaded through-holes of the convex plate on the outer side of the retaining shell 6 are engaged and connected to the positive threaded end of the bidirectional threaded rod 5, the bidirectional threaded rod 5 drives the retaining shell 6 to move vertically upward along the rectangular through-slot of the outer barrel 3. At this time, the retaining shell 6 is higher than the barrel mouth position of the inner barrel 8, and the retaining shell 6 surrounds the outer side of the barrel mouth of the inner barrel 8, preventing the overhaul slag of the aluminum electrolytic cell from overflowing and spilling from the barrel mouth of the inner barrel 8. Since the threaded through-holes of the convex plate on the outer side of the lifting frame 7 are engaged and connected to the reverse threaded end of the bidirectional threaded rod 5, the bidirectional threaded rod 5 drives the lifting frame 7 to move downward along the vertical rod 9, and the lifting frame 7 pulls the push-pull rod 1 1 moves downward synchronously, the push-pull rod 11 pulls the flip cover 1 welded to the connecting rod 10 to perform synchronous flipping and opening work when the baffle shell 6 is raised, and then the aluminum electrolytic cell overhaul slag is poured into the plastic inner barrel 8. After the inner barrel 8 is filled, the hand-held turntable 2 is manually rotated in the opposite direction, and the hand-held turntable 2 drives the two-way threaded rod 5 to rotate. The positive thread end of the two-way threaded rod 5 drives the baffle shell 6 to move downward, and the baffle shell 6 retracts to the inside of the outer barrel 3. The reverse thread end of the two-way threaded rod 5 drives the lifting frame 7 to move upward, and the lifting frame 7 drives the hinged connecting rod 10 to flip through the push-pull rod 11. The connecting rod 10 drives the flip cover 1 to flip and close the barrel mouth of the outer barrel 3, completing the aluminum electrolytic cell overhaul slag storage work.
[0030] All of the above components are mounted, connected, or configured using common mechanical methods, such as welding, threaded connections, and screw connections. The specific structures, models, and coefficients of all components are proprietary technologies, and any method that can achieve a beneficial effect may be employed. The handheld swivel mounts 2 are commonly available on the market and require only connection according to the included instruction manual, so further description is omitted here.
