Description

Technical Field

[0001] This utility model relates to the field of heat preservation furnaces, and in particular to a mobile slag removal and refining equipment. Background Technology

[0002] Currently, cleaning the slag on the surface of molten aluminum in the holding furnace requires a dedicated slag-removing station, staffed by specialized personnel using slag rakes. This manual slag removal is in a harsh working environment, with workers exposed to high temperatures, heat radiation, and dust for extended periods, resulting in high labor intensity. In the event of a furnace explosion, molten aluminum splashes, posing even greater danger to operators. Consequently, more and more people are refusing this work, leading to recruitment difficulties, high staff turnover, and continuously increasing labor costs. Furthermore, manual slag removal is inefficient, and the quality is greatly affected by human factors, resulting in inconsistent product quality, scrap, and economic losses. Therefore, considering the environmental factors of slag removal operations, developing suitable automated equipment to replace manual slag removal is a pressing problem that needs to be solved in this industry.

[0003] The prior art, published under CN 109702182 A, discloses a fully automatic slag remover. This slag remover is equipped with a slag removal robotic arm, on which a slag remover hand and an automatic refining mechanism are mounted. However, the slag remover hand and the automatic refining mechanism are located at the same end of the slag removal robotic arm, causing interference between the slag removal and refining operations, resulting in poor performance. In order to facilitate operation, the prior art makes the slag remover hand and the automatic refining mechanism detachable and replaceable, allowing for alternating use between the slag removal and refining operations. This operation is relatively complex and inefficient. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a mobile slag removal and refining equipment that is easy to operate and does not interfere with the slag removal and refining operations.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a mobile slag removal and refining equipment, including a traveling trolley, a lifting platform is provided above the traveling trolley, a lifting drive is connected between the lifting platform and the traveling trolley, a mechanical beam is rotatably installed at the top of the lifting platform, an automatic slag removal mechanism and an automatic refining mechanism are respectively provided at both ends of the mechanical beam, the end of the automatic slag removal mechanism is rotatably installed at one end of the mechanical beam, and the end of the automatic refining mechanism is rotatably installed at the other end of the mechanical beam.

[0006] As a preferred technical solution, the mechanical crossbeam is provided with a rotating module one, a rotating module two, and a rotating module three. The mechanical crossbeam is rotatably connected to the lifting platform through the rotating module one, the automatic slag removal mechanism is rotatably connected to the mechanical crossbeam through the rotating module two, and the automatic refining mechanism is rotatably connected to the mechanical crossbeam through the rotating module three.

[0007] As a preferred technical solution, the automatic slag removal mechanism includes a slag removal beam frame, the rear end of which is rotatably mounted on the end of the mechanical crossbeam, and the front end of which is provided with a slag removal rake.

[0008] As a preferred technical solution, the front end of the slag removal beam is provided with a rotating frame, the rotating frame is connected to the slag removal beam by rotating left and right, and the slag removal rake is connected to the rotating frame by rotating up and down.

[0009] As a preferred technical solution, the automatic refining mechanism includes a refining mounting base, on which a refining tube is mounted. One end of the refining tube extends outward and the front end is bent downward, and the other end of the refining tube is connected to a refining tank.

[0010] As a preferred technical solution, the traveling trolley is a track trolley.

[0011] As a preferred technical solution, a camera device is also included.

[0012] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. The automatic slag removal mechanism and the automatic refining mechanism are located on both sides of the mechanical crossbeam, ensuring that the slag removal operation and the refining operation are independent and do not interfere with each other. The equipment can operate continuously without changing the operating head. The equipment has good flexibility, is easy to use, and has high operating efficiency.

[0014] 2. Both the automatic slag removal mechanism and the automatic refining mechanism can rotate independently relative to the mechanical beam, and the mechanical beam itself can also rotate, ensuring that the automatic slag removal mechanism and the automatic refining mechanism have multiple degrees of rotational freedom during slag removal operations, enabling large-area and multi-angle operations in a wide and deep furnace.

[0015] 3. The automatic slag removal mechanism and the automatic refining mechanism are located on both sides of the mechanical crossbeam. They are applicable not only to holding furnaces with one furnace opening but also to holding furnaces with two furnace openings. The slag removal and refining operations on the left and right sides are carried out alternately by rotating modules. Slag removal and refining operations can be completed at both furnace openings, and operations can also be carried out between two holding furnaces. The equipment has good versatility.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0023] Example 1:

[0024] like Figure 1 and Figure 2 As shown, the mobile slag removal and refining equipment includes a traveling trolley 100, a lifting platform 200 above the traveling trolley 100, a lifting drive component 300 connecting the lifting platform 200 and the traveling trolley 100, a mechanical beam 400 rotatably mounted on the top of the lifting platform 200, an automatic slag removal mechanism 500 and an automatic refining mechanism 600 respectively at both ends of the mechanical beam 400, the end of the automatic slag removal mechanism 500 being rotatably mounted on one end of the mechanical beam 400, and the end of the automatic refining mechanism 600 being rotatably mounted on the other end of the mechanical beam 400.

[0025] In this embodiment, the traveling trolley 100 is a track trolley. A track 101 is laid on the floor of the workshop or factory. The track 101 is located in front of the furnace opening 701 of the holding furnace 700 and is set along the depth direction of the holding furnace 700, so that the traveling trolley 100 can travel along the track 101 and adjust the distance between the equipment and the holding furnace 700. The wheels of the track trolley can be driven by hub motors, which is existing technology and will not be described in detail here.

[0026] The mechanical beam 400 is equipped with a rotating module 1 401, a rotating module 2 402, and a rotating module 3 403. The mechanical beam 400 is rotatably connected to the lifting platform 200 via rotating module 1 401. The automatic slag removal mechanism 500 is rotatably connected to the mechanical beam 400 via rotating module 2 402. The automatic refining mechanism 600 is rotatably connected to the mechanical beam 400 via rotating module 3 403. Rotating modules 1 401, 2 402, and 3 403 are all existing technologies and will not be described in detail here. Rotating module 2 is located between the two ends of the mechanical beam 400, and is not limited to the middle position.

[0027] The lifting drive component 300 is an electric cylinder, with its two ends connected to the lifting platform 200 and the traveling trolley 100, respectively. The extension and retraction of the electric cylinder achieves the overall raising and lowering of the lifting platform 200, thereby raising and lowering the mechanical beam 400 and its mounted automatic slag removal mechanism 500 and automatic refining mechanism 600. Alternatively, a hydraulic cylinder can be used to replace the electric cylinder.

[0028] To improve the lifting stability of the lifting platform 200, a guide sleeve 301 is provided on the top surface of the traveling trolley 100, and a guide post 302 is provided at the bottom end of the lifting platform 200. The guide post 302 is inserted into the guide sleeve 301 and can slide up and down along the guide sleeve 301 for guidance and positioning.

[0029] The automatic slag removal mechanism 500 includes a slag removal beam 501, with a slag removal mounting base 502 fixed to its rear end. A rotating module 402 is installed at the end of the mechanical beam 400, and the slag removal mounting base 502 is fixed to the rotating output end of the rotating module 402. The rotating module 402 can drive the rotation of the slag removal beam 501. A slag removal rake 503 is provided at the front end of the slag removal beam 501, which is used to remove slag from the surface of the molten aluminum. In this embodiment, the internal width of the holding furnace 700 is approximately 5.9m, the depth is approximately 4m, and the opening of the holding furnace 700 is approximately 0.57m × 1.4m. Therefore, the slag removal beam 501 needs to be a long cantilever beam to ensure that the slag removal rake 503 can fully extend into the interior of the holding furnace 700. To ensure the stability of the cantilever end of the slag removal beam 501, a reinforcing rod is also added.

[0030] The front end of the slag-removing beam 501 is equipped with a rotating frame, which is rotatably connected to the slag-removing beam 501. The slag-removing rake 503 is rotatably connected to the rotating frame. The rotating frame can swing left and right relative to the slag-removing beam 501 via a rotating assembly, which can be a rotary motor or a worm gear, to drive the rotating frame and cause the slag-removing rake 503 to swing left and right relative to the slag-removing beam 501, adapting to position adjustments within the furnace. The slag-removing rake 503 can swing up and down relative to the rotating frame via a lifting assembly, which can be a wire rope or a telescopic cylinder, to drive the slag-removing rake 503 to swing up and down relative to the slag-removing beam 501, adapting to height adjustments.

[0031] The automatic refining mechanism 600 includes a refining mounting base 601. A rotating module 3 403 is mounted on the end of the mechanical beam 400. The refining mounting base 601 is fixed to the rotating output end of the rotating module 3 403. The rotating module 3 403 can drive the rotation of the mechanical beam 400. A refining tube 602 is mounted on the refining mounting base 601. One end of the refining tube 602 extends outward and the front end is bent downward. The other end of the refining tube 602 is connected to a refining tank. The refining tank can be set on the refining mounting base 601 and is equipped with a refining pump inside to control the automatic discharge of the refining liquid.

[0032] In this embodiment, an automatic controller is provided, which can control the automatic walking, lifting, and rotation adjustment of the equipment to achieve automatic slag removal and automatic refining.

[0033] This equipment also includes a photographic device 800, which can be located at the rear end of the automatic refining mechanism, on the mechanical crossbeam, or on the automatic slag removal mechanism. The device is used to take pictures of the furnace interior before and after slag removal, facilitating the assessment of the slag removal process. A picture taken before slag removal is provided to the operator for reference in controlling the operation of the automatic slag removal mechanism, and a picture taken after slag removal is provided to the operator for reference regarding the slag removal effect.

[0034] The working principle of this embodiment is as follows:

[0035] Before the slag removal operation, the mechanical beam 400 is first rotated by the rotating module 401, so that the automatic slag removal mechanism 500 is positioned on one side of the furnace opening 701 to be removed. Then, the height of the slag removal beam 501 and the slag removal rake 503 on it are adjusted by the lifting drive component 300, and the angle of the slag removal beam 501 is adjusted so that the slag removal beam 501 and the slag removal rake 503 are aligned with the furnace opening 701 of the holding furnace 700. Then, the traveling trolley 100 moves along the track 101, driving the slag removal rake 503 to extend into the furnace and protrude above the slag layer. See the attached diagram for the desired state. Figure 3 Then the slag rake 503 is lowered to a suitable height and inserted into a suitable slag layer. Finally, the traveling trolley 100 moves away from the holding furnace 700. During this process, the height and angle of the slag rake 503 are continuously adjusted so that the slag rake 503 can push all the floating slag rakes to the slag pan on the ground at the furnace opening 701, thus completing one slag removal operation.

[0036] After the slag removal operation is completed, the slag removal beam 501 and slag removal rake 503 are removed from the furnace. Then, the rotating module 401 rotates the mechanical beam 400, causing the automatic refining mechanism 600 to rotate to the furnace opening 701 for refining. Before the refining operation, the height of the refining beam 501 and refining tube 602 is adjusted by the lifting drive 300 so that the refining tube 602 corresponds to the furnace opening 701. Then, the traveling trolley 100 moves along the track 101, driving the refining tube 602 into the furnace. The height is adjusted by the lifting drive 300 to the depth of insertion below the surface of the molten aluminum. Then, the refining operation begins. During the refining operation, the angle of the refining tube 602 is continuously adjusted so that the refining tube 602 travels back and forth along a Z-shaped route multiple times, so that the refining area in the furnace reaches the maximum area. After refining is completed, the equipment is reset, furnace opening 701 is closed, and the process is allowed to stand for 40 minutes before the slag is removed and the refining is repeated 2-3 times until the requirements are met.

[0037] In this embodiment, the track 101 can be positioned directly opposite the furnace opening 701. By adjusting the angles of the mechanical beam 400, the automatic slag removal mechanism 500, and the automatic refining mechanism 600, it can be ensured that the automatic slag removal mechanism 500 and the automatic refining mechanism 600 operate within the same furnace opening 701.

[0038] Example 2:

[0039] See Figure 4 At this time, the track 101 is located between the two holding furnaces and between the two furnace openings 701 of the holding furnace. The automatic slag removal mechanism 500 and the automatic refining mechanism 600 on the left and right sides correspond to the positions of the two furnace openings 701 respectively. Through the rotating module 401, the automatic slag removal mechanism 500 and the automatic refining mechanism 600 can rotate alternately between the two furnace openings 701 and can extend into the two furnace openings 701 to remove slag and refine it respectively. In addition, the traveling trolley 100 can also perform back-and-forth operations between the two holding furnaces. Therefore, this equipment can meet the operation requirements of two holding furnaces and four furnace openings 701, and the equipment has a wider range of applications.
