Description

Technical Field

[0001] This application relates to the charging technology of graphitization furnaces, and particularly to an auxiliary charging structure for graphitization furnaces. Background Art

[0002] In the production process of anode materials, it is necessary to load the powder to be graphitized into a graphite crucible, then place the crucible into an Acheson graphitization furnace (hereinafter referred to as the graphitization furnace), and then fill the gaps between the crucibles with resistance material, so that the electrodes provided on the furnace wall of the graphitization furnace are connected in series with the resistance material and the graphite crucible to form a circuit. After being energized and heated, the powder is graphitized under high-temperature conditions.

[0003] Currently, the resistance material is usually packed in a ton bag. When charging the graphitization furnace, after the graphite crucible is placed into the graphitization furnace, the ton bag containing the resistance material is lifted by a crane to the upper part of the graphitization furnace, and then the staff opens the discharge port at the bottom of the ton bag, and the resistance material in the ton bag directly falls into the graphitization furnace for the filling work.

[0004] However, the resistance material is in the form of fine particles. When the resistance material directly falls from the ton bag into the graphitization furnace, a large amount of dust will be generated, and during the falling process of the resistance material, these dusts are not treated, resulting in the dust floating around and polluting the working environment.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following clearly and completely describes the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present application also belong to the scope protected by the present application.

[0032] As Figures 1 - 5 shown:

[0033] An auxiliary charging structure for a graphitization furnace provided by an embodiment of the present application includes a lifting seat 1 whose upper part is connected to the overhead crane hook 6, and a first hook 2 is provided at the lower part of the lifting seat 1.

[0034] A dust suction device 3 capable of collecting dust is provided on the lifting seat 1, and the dust suction device 3 is connected with two symmetrically distributed dust suction covers 4 capable of moving up and down.

[0035] Among them, after the overhead crane hook 6 hoists the ton bag 5, the dust suction cover 4 can move to the lower side of the ton bag 5.

[0036] During use, first hang the lifting seat 1 on the overhead crane hook 6, then hang the first hook 2 on the ton bag 5, hoist the ton bag 5 by the overhead crane and transport it above the graphitization furnace, then move the two dust suction covers 4 to the lower side of the ton bag 5, and start the dust suction device 3. The dust suction device 3 sucks the air in the two dust suction covers 4 to generate negative pressure in the dust suction covers 4. Then open the discharge port at the bottom of the ton bag 5, and the resistance material in the ton bag 5 falls into the graphitization furnace for the filling work. At the same time, the two dust suction covers 4 can suck the dust generated during filling into the dust suction device 3 and be collected by the dust suction device 3.

[0037] The auxiliary charging structure for the graphitization furnace provided by this embodiment, by including a lifting seat 1 whose upper part is connected to the overhead crane hook 6, a first hook 2 is provided at the lower part of the lifting seat 1, a dust suction device 3 capable of collecting dust is provided on the lifting seat 1, the dust suction device 3 is connected with two symmetrically distributed dust suction covers 4 capable of moving up and down, and after the overhead crane hook 6 hoists the ton bag 5, the dust suction cover 4 can move to the lower side of the ton bag 5, so that when filling the resistance material into the graphitization furnace, the dust suction covers 4 on both sides of the ton bag 5 can simultaneously suck the dust generated when the resistance material falls at two positions, thereby avoiding the dust from spreading everywhere and improving the working environment quality of the staff.

[0038] Moreover, since the dust suction device 3 is provided on the lifting seat 1 and the dust suction device 3 is connected to the dust suction cover 4, when the overhead crane drives the ton bag 5 to move and fill the resistance material into the graphitization furnace through the lifting seat 1 and the first hook 2, the two dust suction covers 4 can move synchronously with the ton bag 5. Therefore, when the ton bag 5 moves for discharging, the dust suction work can be ensured to proceed normally.

[0039] In some embodiments of the present application, the dust suction device 3 includes a box body 301, a suction fan 302 is installed at the upper end of the box body 301, a horizontally distributed filter screen 303 is installed inside the box body 301, and a dust suction pipe 304 horizontally penetrating the box body 301 and hermetically rotatably connected to the box body 301 is provided below the filter screen 303.

[0040] Specifically, the dust suction pipe 304 is rotatably connected to the box wall of the box body 301 through a sealed bearing. The two ends of the dust suction pipe 304 are centrosymmetric about the center of the box body 301, and the two ends of the dust suction pipe 304 are of a closed structure.

[0041] A through-hole group 3041 located inside the box body 301 is formed in the dust suction pipe 304, so that the dust suction pipe communicates with the box body. Specifically, the through-hole group 3041 is composed of a plurality of long holes distributed in a ring shape. The dust suction pipe 304 is connected with a driving mechanism 306 that can drive it to rotate and lock. Both ends of the dust suction pipe 304 are connected to the dust suction hood 4 through rubber hoses 305. Specifically, one end of the rubber hose 305 is communicated with and fixedly connected to the dust suction pipe 304 in a sealed manner, and the other end of the rubber hose 305 is connected to the dust suction hood 4. The rubber hose 305 is wound around the dust suction pipe 304.

[0042] During use, the driving mechanism 306 drives the dust suction pipe 304 to rotate. After the dust suction pipe 304 rotates, the rubber hose 305 is wound or released. After the dust suction pipe 304 winds the rubber hose 305, the rubber hose 305 drives the dust suction hood 4 to move upward. After the dust suction pipe 304 releases the rubber hose 305, the suction hood moves downward according to its own gravity, so as to adjust the position of the dust suction hood 4.

[0043] During dust suction, the exhaust fan 302 is started. After the exhaust fan 302 works, a negative pressure is generated inside the dust suction hood 4. The dust suction hood 4 sucks dust. The dust enters the dust suction hood 4 and flows upward along the rubber hose 305 and the dust suction pipe 304 into the box body 301. The filter screen 303 intercepts the dust, and the dust finally settles at the bottom of the box body 301.

[0044] In order to facilitate the dust suction pipe 304 to wind the rubber hose 305. In some embodiments of the present application, two limiting plates 307 are fixed to both ends of the dust suction pipe 304, and the rubber hose 305 is wound between the two limiting plates 307.

[0045] In some embodiments of the present application, the filter screen 303 includes a net plate 3031. A filter cloth 3032 adapted to it is fixed to the lower end of the net plate 3031, and the edge of the net plate 3031 is hermetically connected to the inner wall of the box body 301.

[0046] In this embodiment, by providing the filter cloth 3032, the filtering effect of dust can be improved.

[0047] In some embodiments of the present application, the lifting seat 1 includes two symmetrically distributed side plates 101. An annular plate 102 is hermetically fixed between the two side plates 101, and the upper and lower parts of the side plates 101 extend out of the annular plate 102.

[0048] A connecting column 103 for connecting with the overhead crane hook 6 is fixed between the upper parts of the two side plates 101. Specifically, in order to improve the stability of the connection between the connecting column 103 and the side plate 101, the connecting column 103 penetrates through the side plate 101 and is fixedly welded to the side plate 101. A first hook 2 is connected between the lower parts of the two side plates 101. A box body 301 is formed between the annular plate 102 and the two side plates 101.

[0049] In this embodiment, by providing two side plates 101, a box body 301 is provided between the two side plates 101, and both the connecting column 103 and the first hook 2 are directly connected to the two side plates 101. Not only is the stability relatively high when lifting the ton bag 5, but after the box body 301 is located between the two side plates 101, it has the effects of a compact structure and small occupied space.

[0050] During use, the connecting column 103 is hung on the overhead crane hook 6, and the connection work between the lifting seat 1 and the overhead crane hook 6 can be achieved.

[0051] In order to further improve the stability of the lifting seat 1. In some embodiments of the present application, a plurality of reinforcing bars 104 are fixed between the upper parts of the two side plates 101 and between the lower parts of the two side plates 101.

[0052] In order to facilitate the cleaning of the dust collected in the box body 301. In some embodiments of the present application, the lower end of the box body 301 is composed of a horizontal section and an inclined section. A dust discharge hopper 308 is hermetically fixed to the horizontal section. A sealing cover 309 is detachably fixed to the lower end of the dust discharge hopper 308. The dust in the box body 301 can be cleaned by removing the sealing cover 309.

[0053] In some embodiments of the present application, the driving mechanism 306 includes a self-locking motor 3061. The self-locking motor 3061 is fixed on one of the side plates 101, and the self-locking motor 3061 is connected to the dust suction pipe 304 through a chain drive mechanism 3062.

[0054] In this embodiment, by providing the self-locking motor 3061, after the height position of the dust suction hood 4 is adjusted, since the output shaft of the self-locking motor 3061 is locked, and the output shaft of the self-locking motor 3061 is connected to the dust suction pipe 304 through the chain drive mechanism 3062, therefore, after the output shaft of the self-locking motor 3061 is locked, the dust suction pipe 304 will not rotate randomly, and thus the locking effect of the dust suction pipe 304 is achieved.

[0055] The self-locking motor 3061 in this embodiment adopts the self-locking motor 3061 in the prior art and will not be described in detail.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
