Technical Field

[0001] The utility model relates to the technology of lifting a furnace cover, in particular to a furnace cover lifting mechanism for aluminum material processing. Background Technique

[0002] With the increasing demand for product light weight, aluminum metal has received more and more attention. When the existing aluminum materials are recycled and reused, they need to be put into a melting furnace for melting, and a furnace cover lifting mechanism is required when the melting furnace is in use.

[0003] In order to simplify the structure, some existing biomass aluminum melting furnaces are designed to be open during melting for easy feeding and observation. However, the open design will cause the temperature to drop too fast and is not conducive to the heat preservation of aluminum materials. After setting a furnace cover, it will affect the feeding operation, and the furnace cover also needs to be operated to open and close. If manually operated, it will increase the use risk and reduce the use safety. Therefore, we propose a furnace cover lifting mechanism for aluminum material processing to solve the problems encountered above. Content of the Utility Model

[0022] Next, the technical solutions of the present utility model will be described clearly and completely in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 As shown, a furnace cover lifting mechanism for aluminum material processing includes a connecting arm 1. The connecting arm 1 is connected to the outer wall of the furnace body. The upper end of the connecting arm 1 is fixedly connected with a top plate 2. The connecting arm 1 is used to facilitate the overall connection of the device with the furnace body. The top plate 2 is used to fix part of the lifting component structure at the top. The front and rear sides of the top and bottom of the connecting arm 1 are respectively fixedly connected with side plates 3; a lifting component, the lifting component includes a tooth plate 4 slidably connected to the front side of the rear side plate 3 among the two side plates 3. One side of the connecting arm 1 is rotatably connected with a worm 5. A connecting shaft 6 is rotatably connected between the two side plates 3. The outer left side of the worm 5 is fixedly connected with a first gear 7. The outer rear side of the connecting shaft 6 is fixedly connected with a worm gear 8. The worm gear 8 is engaged with the worm 5. The design of the engagement of the worm gear 8 and the worm 5 enables the power to be transmitted unidirectionally only, avoiding the problem that when the first gear 7 is not engaged with the tooth plate 4, the furnace top cover rotates and resets without being affected by the pulling force of the first furnace cover wire 10. The outer front side of the connecting shaft 6 is fixedly connected with a first wire roller 9. A first furnace cover wire 10 is wound around the outer side of the first wire roller 9. The middle of the top of the top plate 2 is rotatably connected with an intermediate rod 11 through a connecting piece. The outer side of one end of the intermediate rod 11 is fixedly connected with a second gear 12. The front and rear sides of the top of the top plate 2 are respectively rotatably connected with outer edge rods 13 through connecting pieces. The outer sides of both ends of the outer edge rod 13 are respectively fixedly connected with second wire rollers 14. Second furnace cover wires 15 are wound around the outer sides of the second wire rollers 14. The outer edge rod 13 and the intermediate rod 11 are connected through a transmission structure.

[0024] The transmission structure includes two sprockets 16 respectively fixedly connected to the outer sides of the outer edge rod 13 and the intermediate rod 11. The same chain belt 17 is arranged between the outer sides of the two sprockets 16. The transmission of power through the two groups of sprockets 16 and the chain belt 17 enables the tooth plate 4 to drive the two outer edge rods 13 to rotate simultaneously when engaged with the second gear 12, facilitating the operation by a single power component.

[0025] A cross plate 18 is fixedly connected to one side between two side plates 3. One end of the worm 5 is rotatably connected to the cross plate 18. The cross plate 18 is used to support the worm 5 to improve the fixing stability.

[0026] The furnace cover includes an annular body and a furnace top cover that rotates inside the annular body. One end of the first furnace cover wire 10 is connected to the top of the furnace top cover. One end of the second furnace cover wire 15 can be connected to the four corners of the top of the annular body. The two groups of wires are respectively connected to the furnace top cover and the annular body, which can facilitate the rotation and opening of the furnace top cover and the overall rising movement of the annular body and the furnace top cover, facilitating driving and control.

[0027] A square groove is provided at the top of the connecting arm 1. The connecting arm 1 is of a U-shaped structure. The square groove is used for the tooth plate 4 to pass through when it rises to avoid interference.

[0028] A support sleeve is further provided on the lower side of the furnace body outer wall. A hydraulic cylinder 19 is fixedly connected to the inner side of the support sleeve. The output end of the hydraulic cylinder 19 is fixedly connected to the bottom end of the tooth plate 4. The hydraulic cylinder 19 is used to provide power, and the support sleeve is used to connect and fix the hydraulic cylinder 19 and the furnace body.

[0029] When the present utility model is specifically implemented: when it is necessary to feed aluminum materials for processing, the hydraulic cylinder 19 is controlled to work through the controller. By driving the tooth plate 4 to move upward, its upper tooth shape meshes with the first gear 7 to drive the worm 5 to rotate. The worm 5 meshes with the worm gear 8 to drive the connecting shaft 6 to rotate. The first wire roller 9 on it winds and unwinds the wire to make the furnace top cover rotate and open around a fixed axis to a certain angle. At this time, aluminum materials can be put into the furnace. When the aluminum material processing is completed and no feeding is required, the output end of the hydraulic cylinder 19 can be controlled to move in the reverse direction, and the furnace top cover is driven to rotate and close in the reverse direction through the above transmission. When it is necessary to open the annular body and the entire furnace top cover, on the basis of the rotation and opening of the furnace top cover, the output end of the hydraulic cylinder 19 can be controlled by the controller to continue to drive the tooth plate 4 to move upward, so that its upper tooth shape no longer meshes with the first gear 7, but instead moves to a position meshing with the second gear 12. At this time, the rotating second gear 12 drives the intermediate rod 11 to rotate, and drives the two outer edge rods 13 to rotate through the transmission of the two groups of chain wheels 16 and the chain belt 17, and makes the four second wire rollers 14 on them rotate. By winding the second furnace cover wire 15 to the outside thereof, the annular body and the furnace top cover are driven to rise as a whole, so that the top of the aluminum smelting furnace is completely opened.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made.
