Description

Technical Field

[0001] The utility model relates to the technical field of graphitization devices, in particular to a dust-proof device for the top of a graphitization box furnace. Background Art

[0002] The anode material is the core component of new energy power batteries. With the booming development of the new energy industry, the production capacity of anode materials has increased by leaps and bounds. Graphitization is the most important link in the production of anode materials, which is a process of high-temperature modification of anode raw materials at 3000°C. At present, most of the market uses Acheson graphitization furnaces, internal heat series-connected graphitization furnaces and box-type graphitization furnaces to complete graphitization production.

[0003] The top of the existing graphitization furnace is generally sealed with felt. However, during operation, the graphitization furnace will generate high temperature. After high temperature, fluff often enters the raw materials, which is not conducive to the high-quality production of graphite materials for battery anodes, and the fluff fiber content is unstable; in addition, since the tooling and labor protection supplies used by workers also contain fluff fibers, if carelessly, the production raw materials will be mixed with fluff during the operation process.

Two receiving bins are fixedly connected to both sides of the top of the furnace body. Two groups of meshing driving gears and driven gears are arranged in each of the two receiving bins. One end of each of the four driving gears is fixedly connected to a rotating rod. The four rotating rods respectively penetrate through both sides of the two receiving bins.

[0009] As a further improvement of the present utility model, sliders are fixedly connected to both sides of the dust-proof layer, and two vertical chutes for the two sliders to slide are fixedly connected to the top of the furnace body.

[0010] As a further improvement of the present utility model, clamping columns are fixedly connected to the bottom ends of the two sliders, and two clamping grooves for the two clamping columns to be clamped are formed in the top of the furnace body.

[0028] The present utility model provides as shown in the appendix Figures 1-10As shown in the figure, a dust-proof device for the top of a graphitization box furnace includes a furnace body 1 and a cover 2. The furnace body 1 is hermetically connected to the cover 2. A dust-proof layer 3 is slidably connected to the top of the furnace body 1. Four limiting components 4 are fixedly connected to the top of the furnace body 1, and the four limiting components 4 are respectively located at the four corners of the dust-proof layer 3. Two accommodating bins 5 are fixedly connected to both sides of the top of the furnace body 1. Two sets of meshing driving gears 6 and driven gears 7 are arranged inside the two accommodating bins 5. One end of each of the four driving gears 6 is fixedly connected to a rotating rod 8. The four rotating rods 8 respectively penetrate through both sides of the two accommodating bins 5. The four driven gears 7 are fixedly connected to the inner wall of the accommodating bin 5 through a rotating shaft cylinder 17. Four limiting columns 9 are respectively threadedly connected to the four driven gears 7. The four limiting columns 9 respectively penetrate through the accommodating bin 5 and extend to the four limiting components 4 and the dust-proof layer 3.

[0029] As Figure 2 , 5 , as shown in Figures 6 and 7, the limiting component 4 includes a rotating seat 4.1 fixedly connected to the furnace body 1. A limiting plate 4.2 is rotatably connected to the rotating seat 4.1 through a rotating shaft. The limiting plate 4.2 is provided with a through hole for the limiting column 9 to pass through. The dust-proof layer 3 is provided with a limiting groove 4.3 for the limiting plate 4.2 to be clamped. A clamping hole 10 for the limiting column 9 to be clamped is provided on one inner wall of the limiting groove 4.3. The provided limiting component 4, limiting column 9 and clamping hole 10 provide a firm fixing effect for the dust-proof layer 3.

[0030] As Figure 7 shown in the figure, a connecting member 11 is fixedly connected to one end of the rotating rod 8. It is convenient for the user to drive the driving gear 6, which is convenient and stable.

[0031] As Figure 2 , 3 shown in the figure, sliding blocks 12 are fixedly connected to both sides of the dust-proof layer 3. Two vertical sliding grooves 13 for the two sliding blocks 12 to slide are fixedly connected to the top of the furnace body 1. The provided sliding blocks 12 and vertical sliding grooves 13 provide a good guiding effect for separating the dust-proof layer 3 from the furnace body 1. Clamping columns 14 are fixedly connected to the bottom ends of the two sliding blocks 12. Two clamping grooves 15 for the two clamping columns 14 to be clamped are provided on the top of the furnace body 1. The provided clamping columns 14 and clamping grooves 15 facilitate the firm connection between the dust-proof layer 3 and the furnace body 1 and increase the firmness between the two.

[0033] As Figure 8 shown in the figure, the rotating shaft cylinder 17 is rotatably connected to the driven gear 7 through a bearing 18. The driven gear 7 is connected to the accommodating bin 5 through the rotating shaft cylinder 17. The provided bearing 18 can make the limiting column 9 connected by thread inside the driven gear 7 move horizontally when the driven gear 7 rotates.

[0034] Working principle: When the present utility model is specifically implemented, first, the staff replaces items such as work tools, gloves, boots, etc. that may generate fluff fibers in the working environment, reducing the entry of fluff fibers from the staff into the furnace body 1. Place the pre-prepared production raw materials into the furnace body 1, slide the dust-proof layer 3 into the two vertical chutes 13 through the two sliders 12 on both sides, and engage the clamping post 14 with the clamping slot 15. Rotate the limiting plate 4.2 to engage it with the limiting slot 4.3. Rotate the adapter 11 inward (i.e., in the direction of the dust-proof layer 3) in sequence, drive the four driving gears 6 to rotate inward through the four rotating rods 8 in sequence, and make the four driven gears 7 meshing with the four driving gears 6 rotate accordingly. Since the limiting post 9 is threadedly connected to the driven gear 7, and the driven gear 7 is rotationally connected to the rotating shaft cylinder 17 through the bearing 18, the driven gear 7 drives the limiting post 9 to move forward, pass through the accommodation chamber 5 and the limiting slot 4.3, and make the limiting post 9 engage with the clamping hole 10. Finally, the dust-proof layer 3 is reliably connected to the furnace body 1, and the worker can perform subsequent operations.
