Description

Technical Field

[0001] This utility model relates to the technical field of aluminum liquid refining equipment, specifically a lightweight slag remover. Background Technology

[0002] The transformation and improvement of the smelting and casting workshop is of paramount importance for lean management in the electrolytic aluminum industry and also represents potential for the automation and intelligent upgrading of aluminum plants. For a long time, slag removal and charging tasks in the domestic electrolytic aluminum industry have primarily been performed by forklifts. The risks of this operation are as follows: First, safety: forklifts are special vehicles; unauthorized modifications, poor protective measures, and the constant movement in front of the furnace pose significant safety hazards. Second, occupational health issues: the furnace area produces a large amount of smoke and dust during slag removal, and the high temperatures pose serious risks to operators. Third, forklift operation can easily damage the furnace walls and access doors. Fourth, the forklift's slag removal is not smooth enough; the slag removal arm wobbles, resulting in poor slag removal and loss of molten aluminum.

[0003] Currently, the market commonly uses manually operated slag loaders, forklift-modified slag loaders, and separate manually operated refining slag loaders. Both manual slag loaders and refining slag loaders require manual operation close to the furnace opening, posing significant safety hazards. They also have low slag removal efficiency, long working hours, and are unsuitable for mass production. Especially during refining, workers need to wear heat-resistant clothing while working in front of the furnace, where the high temperatures pose a significant safety risk. Utility Model Content

[0004] To address the problems of the modified muck loader being difficult to mass-produce and still requiring manual operation, this utility model provides a lightweight muck loader.

[0005] The technical solution of this utility model is as follows:

[0006] A lightweight muck loader includes a mobile trolley, the mobile trolley is provided with a connecting frame, and the connecting frame is liftable. The connecting frame is rotatably connected to a tilting frame, and the tilting frame is rotatably connected to a guide rail. The plane of rotation of the tilting frame relative to the connecting frame is perpendicular to the plane of rotation of the tilting frame relative to the guide rail.

[0007] The guide rail is equipped with a working frame that can move along the length direction. The working frame includes a hollow rod and a refining tube installed inside the hollow rod. The two ends of the refining tube extend outward relative to the hollow rod and one end is inclined downward. The hollow rod is equipped with a detachable slag rake at the end near the inclined end of the refining tube.

[0008] The work frame is equipped with a refining tube for refining and a slag rake for slag removal. The refining and slag removal operations do not require manual operation and can be adjusted in both horizontal and vertical directions as needed. It can also be raised and lowered to adapt to furnace openings of different heights.

[0009] The hollow rod is fixed to the slag rake by having two vertical slots symmetrically arranged at the inclined end of the hollow rod near the refining tube. The slag rake is inserted and fixed into the slots. The slot design prevents the slag rake from rotating.

[0010] The specific structure of the above-mentioned slag rake is as follows: the slag rake includes a slag rake body, a U-shaped opening is provided on the top of the slag rake body, and the U-shaped opening corresponds to the slot and a locking pin is provided at the opening end.

[0011] The refining tube is fixed by means that a plurality of clamping bolts are provided through the hollow rod at the end near the inclined end of the refining tube to abut against the refining tube.

[0012] To allow the hollow rod to move normally, the guide rail is provided with a guide limit seat on the side near the inclined end of the refining tube. The hollow rod passes through the guide limit seat, and the guide limit seat is provided with a support lifting wheel below the hollow rod.

[0013] The hollow rod is driven by having one end of it away from the guide limit seat mounted on a movable seat, which is movable relative to the guide rail.

[0014] To prevent the hollow rod from deforming, a tension rib is provided on the upper part of the hollow rod along its length, and the tension rib is arched.

[0015] As a preferred embodiment, the horizontal plane of the inclined end of the refining tube is lower than the horizontal plane of the lower end of the slag rake. This ensures that the refining tube can extend into the molten aluminum.

[0016] The specific configuration of the aforementioned slag rake is such that the extension direction of the rake claws is perpendicular to the length direction of the working frame.

[0017] In order to collect aluminum slag, the slag rake is arched and symmetrically arranged about the working frame.

[0018] The beneficial effects of this utility model are as follows: This utility model is a lightweight slag remover, which differs from existing manual or forklift-assisted slag removal methods. This device has an extra-long working frame, and the guide rail on which the work is located can tilt up and down and rotate at the inner angle. Through the extension and retraction of the working frame relative to the guide rail, it can complete the tasks of stirring, slag removal, and refining. At the same time, the moving trolley can also move laterally in front of the furnace to complete the operation of the entire furnace. It can also be adapted to different furnace opening heights. Furthermore, the slag remover rake of the above-mentioned slag remover is easy to disassemble and replace, as is the refining tube. After reaching the end of its service life in high-temperature environments, no changes to other structures are required; these two components can be replaced separately. Attached Figure Description

[0027] like Figure 1-3 The illustrated lightweight slag remover includes a mobile trolley 1, which can move on the ground to drive the equipment to operate at different positions. The mobile trolley 1 is equipped with a connecting frame 2, which is mounted on a gantry. The connecting frame 2 is fixed to the gantry by a lifting electric cylinder. Therefore, by driving the lifting electric cylinder, the connecting frame 2 can be raised and lowered within a certain height range. For aluminum molten furnaces of different specifications, it can adaptively adjust according to the actual furnace opening height. The connecting frame 2 is then rotatably connected to a tilting frame 3. The connecting frame 2 is equipped with a rotating platform that connects to the tilting frame 3. Therefore, while having a lifting function, it can also rotate in the horizontal plane using the rotating platform to adjust the angle. Finally, the tilting frame 3 is rotatably connected to the guide rail 4. It should be noted that the rotation plane of the tilting frame 3 relative to the connecting frame 2 is perpendicular to the rotation plane of the tilting frame 3 relative to the guide rail 4. That is to say, the tilting frame 3 is connected to the guide rail 4 through a telescopic electric cylinder or a pneumatic cylinder, and can rotate in the vertical plane. Through the above design, it is possible to adjust the height while also rotating in both the horizontal and vertical directions, thus adapting to various working conditions.

[0028] It should be noted that the guide rail 4 is equipped with a working frame 7 that can move along the length direction. That is to say, the working frame 7 can move within the range of the guide rail 4 and extend into the aluminum liquid furnace to perform operations. Moreover, the working frame 7 includes a hollow rod 71 and a refining tube 72 installed inside the hollow rod 71. This socketed design ensures that the refining tube 72 will not bend even when it is long. Furthermore, both ends of the refining tube 72 extend outward relative to the hollow rod 71, with one end inclined downward and the other end not bent. When the bent section is damaged, it can be pulled out from the hollow rod 71 and a new refining tube 72 can be replaced. The hollow rod 71 is equipped with a detachable slag rake 8 at the end near the inclined end of the refining tube 72 to facilitate slag removal operations.

[0029] And such as Figure 3 As shown, the horizontal plane of the inclined end of the refining tube 72 is lower than the horizontal plane of the lower end of the slag rake 8. This ensures that the refining tube 72 can extend into the molten aluminum.

[0030] It is important to note that, such as Figure 4 As shown, the refining tube 72 is fixed by having multiple clamping bolts 75 inserted through the hollow rod 71 at its inclined end near the refining tube 72. By tightening the clamping bolts 75, displacement of the refining tube 72 within the hollow rod 71 can be prevented, thus avoiding free rotation and affecting normal refining operations. After loosening the clamping bolts 75, the refining tube 72 can be pulled out from the hollow rod 71.

[0031] The above structure enables the operation frame 7 to be equipped with a refining tube 72 for refining and a slag rake 8 for slag removal. The refining and slag removal operations can be carried out by simply driving the operation frame 7. The two operations do not interfere with each other. It can be seen that the refining and slag removal operations do not need to be completed manually. The horizontal and vertical angles can be adjusted according to the needs. It can also be raised and lowered to adapt to furnace openings of different heights.

[0032] In a preferred embodiment, the hollow rod 71 is fixed to the slag rake 8 by symmetrically providing two vertical slots 74 at the end of the hollow rod 71 near the inclined end of the refining tube 72. The slag rake 8 is inserted and fixed into the slots 74. The design of the slots 74 can prevent the slag rake 8 from rotating relative to the hollow rod 71, and can also position the installation position of the slag rake 8. For adaptability, multiple slots 74 can be provided. The specific structure of the slag rake 8 is as follows: the slag rake 8 includes a rake body 81, and a U-shaped opening is provided on the top of the rake body 81. The U-shaped opening corresponds to the slot 74, and a locking pin 82 is provided at the opening end. In use, the locking pin 82 is removed, and then the U-shaped opening is inserted into the slot 744 to re-fix the locking pin 82. Figure 4 The above-mentioned fixed state can be achieved as shown.

[0033] like Figure 4 As shown, the slag rake 8 is specifically configured such that the extension direction of the rake claws is perpendicular to the length direction of the working frame 7, forming a slag-removing plane. Multiple rake claws are spaced apart along the length direction to prevent the slag from being pushed away. For collecting aluminum slag, the slag rake 8 is arched and symmetrically arranged about the working frame 7. This allows for the collection of slag, preventing it from detaching from the sides of the slag rake 8.

[0034] Finally, as Figure 1 As shown, for the normal movement of the hollow rod 71, the guide rail 4 is provided with a guide limiting seat 6 on the side near the inclined end of the refining tube 72. The hollow rod 71 passes through the guide limiting seat 6, and the guide limiting seat 6 is provided with a support lifting wheel below the hollow rod 71. This supports the hollow rod 71 while reducing the resistance to its movement. The hollow rod 71 is driven by having one end away from the guide limiting seat 6 mounted on a movable seat 5, which is movable relative to the guide rail 4. The movable seat 5 can be driven by a chain drive; the relevant structure will not be described in detail.

[0035] If the hollow rod 71 is also quite long, in order to prevent its deformation from causing the refining tube 72 to also deform, a tension rib 73 is provided on the upper part of the hollow rod 71 along the length direction, and the tension rib 73 is arched.
