[0002] A submerged arc furnace, also known as an electric arc furnace or a resistance furnace, is mainly used for smelting raw materials such as ores, carbonaceous reducing agents, and solvents. It is widely used in the production of ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and silicomanganese alloys, playing an important role in the metallurgical industry as an important industrial raw material. At the same time, it is also a key device for the production of chemical raw materials such as calcium carbide.

[0003] When some existing traditional small submerged arc furnaces are in use, the feeding is generally carried out through the opening on the top furnace plate. However, the opening of the furnace plate is generally small. If there is a large amount of material to be added, the feeding will be time-consuming and not convenient enough. At the same time, for some existing small traditional submerged arc furnaces, the discharging is generally carried out by opening a discharging pipe on the lower outer wall of the furnace body for discharging. However, during discharging, some materials are likely to remain at the bottom of the furnace and are also likely to remain inside the discharging pipe, which is not very practical. Therefore, an automatic lifting and heat preservation device for the cover of a submerged arc furnace is proposed to solve the above problems. Content of the Utility Model

[0029] Referring to Figures 1-3 , an embodiment provided by the present utility model: A submerged arc furnace cover automatic lifting and heat preservation device includes a housing 1, inside which a heating ring and an electrode ring are arranged for heating. An outer part of the housing 1 is fixedly connected with a mounting ring 11 for cooperating with the connection with the driving assembly 6. A cover 2 is arranged on an upper part of the housing 1 for cooperating with charging and discharging. A smoke exhaust pipe 3 penetrates and is movably connected to a middle part of the cover 2 for discharging flue gas during processing. First cylinders 5 are arranged on both left and right sides of the cover 2 for automatically lifting the cover 2. A base 4 is arranged below the first cylinders 5 for cooperating with connecting various components. A driving assembly 6 is arranged on a top of the base 4 for pushing the housing 1 to assist in discharging materials.

[0030] Furthermore, connecting frames 21 are fixedly connected to both left and right sides of the cover 2 for cooperating with the connection between the cover 2 and the first cylinders 5, and the first cylinders 5 are fixedly connected thereto. A furnace plate 22 is movably connected to a front side of the cover 2 for cooperating with charging. A mounting seat 41 is fixedly connected to a middle part of a top surface of the base 4 for cooperating with the installation of the first cylinders 5, and a bottom of the first cylinders 5 is fixedly connected thereto.

[0031] As Figure 4As shown in the figure, the pushing component 6 includes a cross bar 61 for connecting various components. The cross bar 61 is fixedly connected to the base 4. At the rear part of the top surface of the cross bar 61, a vertical rod 62 is fixedly connected for cooperating with the connection of the support rod 66. On the front and rear sides of the lower part of the vertical rod 62, reinforcing plates 63 are fixedly connected between the vertical rod 62 and the cross bar 61 respectively, for strengthening the connection between the cross bar 61 and the vertical rod 62 and improving the supporting force of the vertical rod 62. At the upper part of the front side of the vertical rod 62, a connecting plate 64 is fixedly connected for cooperating with the connection of the support rod 66. The pushing component 6 further includes a mounting block 68, one end of the support rod 66 is connected thereto, and the mounting block 68 is fixedly connected to the mounting ring 11. Between the upper and lower parts of the mounting block 68 and the two connecting plates 64, support rods 66 are respectively movably connected. The number of the support rods 66 is two. A second cylinder 65 is jointly arranged between the lower support rod 66 and the front reinforcing plate 63 for cooperating with the support rod 66 to push the housing 1 to tilt and assist in discharging materials. At both the upper and lower ends of the second cylinder 65, connecting pieces 651 are fixedly connected for the connection between the second cylinder 65, the support rod 66 and the reinforcing plate 63.

[0032] Working principle: When in use, when it is necessary to put materials into the housing 1, the first cylinder 5 is started. The first cylinder 5 will then push the connecting frame 21 upward. The cover 2 connected to the connecting frame 21 will be driven to move upward along the exhaust pipe 3. Then, through the opening between the cover 2 and the housing 1, materials are added into the housing 1. After the materials are added, the cover 2 is controlled by the first cylinder 5 to move downward to cover tightly. Then, the heating ring in the housing 1 is started to melt the materials. After melting, when it is necessary to take out the materials, the first cylinder 5 is started again to open the cover 2 upward again. Then, the pushing component 6 is started. The second cylinder 65 will then push the connecting block 661 connected through the connecting piece 651, drive the support rod 66 connected to the connecting block 661, and thus drive the mounting ring 11 to move through the mounting block 68. At the same time, the other support rod 66 connected to the mounting block 68 will be driven accordingly. The mounting ring 11 will drive the housing 1 to lift and tilt forward to assist the complete discharge of the materials inside. After the materials are discharged, the housing 1 is controlled by the second cylinder 65 to reset, and then the cover 2 is lowered and covered by the first cylinder 5.
