[0002] Lithium-ion batteries have become the darling of the energy storage and conversion device market due to their portability and high utilization rate. At present, graphitization furnaces are often used to prepare negative electrode materials for lithium-ion batteries. In the graphitization power transmission process, the air holes on the graphitization furnace will produce harmful mixed gases such as carbon monoxide and sulfur dioxide after ignition, making the exhaust gas concentration at the work site around the furnace room high, which is harmful to the physical and mental health of the workers. Therefore, a smoke hood is usually used to collect and treat the smoke on the top of the graphitization furnace.

[0003] In the related art, due to the high furnace height of the graphitization furnace, the smoke hood installed on the top of the furnace has the problems of small smoke suction force and poor air suction effect, resulting in poor smoke exhaust effect; at the same time, the smoke that cannot be discharged in time will gather in the smoke hood to form high-pressure smoke. The high air pressure will cause the high-pressure smoke to leak and escape from the contact surface between the smoke hood and the top of the graphitization furnace, polluting the working environment and endangering the physical and mental health of the workers.

[0029] See also Figures 1 to 3 The embodiment of the present application provides a smoke collecting assembly for a graphitization furnace, which includes: a cover body 100, provided with a gas supply window 101 and a connector 102; a smoke pipe assembly 200, connected to the connector 102; an adjusting member 300, slidably arranged on the cover body 100 corresponding to the gas supply window 101, and the adjusting member 300 can be opened to expose or closed to block the gas supply window 101, so as to connect or separate the internal space of the cover body 100 and the external environment; and a sealing member 400, which is arranged at the opening of the cover body 100, and the cover body 100 is connected to the furnace body 10 of the graphitization furnace through the sealing member 400.

[0030] In this embodiment, the smoke collecting assembly is connected to the smoke pipe assembly 200 at the connector 102 of the cover body 100, so that the smoke overflowing from the furnace body 10 can be collected by the cover body 100 and then discharged through the smoke pipe assembly 200, so as to facilitate the collection and centralized treatment of the smoke generated in the furnace body 10, and avoid the toxic smoke directly entering the surrounding environment, which seriously affects the physical and mental health of the operators. In addition, the cover body 100 is set above the furnace body 10 through the seal 400 to enhance the sealing of the connection between the cover body 100 and the furnace body 10. In this way, on the one hand, it can prevent the smoke from escaping from the gap between the two to cause pollution, and improve the air quality around the graphitization furnace; on the other hand, the seal 400 can form a closed chamber between the cover body 100 and the furnace body 10. At this time, only a small fan suction force is needed to achieve rapid suction of the smoke, avoid the accumulation of smoke in the cover body 100, and the smoke exhaust effect is excellent. In addition, an adjusting member 300 is provided at the air supply window 101 on the cover body 100, so that the air supply window 101 can be opened and closed through the adjusting member 300, thereby realizing the connection and isolation between the internal space of the cover body 100 and the external environment, providing sufficient combustion oxygen to the flame in the cover body 100 while ensuring that the interior of the cover body 100 is in a slightly negative pressure to facilitate the suction and discharge of smoke.

[0031] Specifically, the smoke collecting assembly is configured as a composite component including at least a cover body 100, a smoke pipe assembly 200, an adjusting member 300 and a sealing member 400. The cover body 100 may be a box-shaped steel structure with an opening, which may be connected to the top opening of the furnace body 10 by means of fasteners such as screws / bolts or structures such as snaps, so as to form a smoke collection area on the top of the furnace body 10, so as to collect and centrally process the smoke generated by the furnace body 10; an air supply window 101 and a connector 102 are provided on the cover body 100, and the air supply window 101 connects the internal space of the cover body 100 with the external environment to provide oxygen to the flame in the cover body 100; the connector 102 may be a cylindrical connecting pipe, which may be welded to the cover body 100 and connected to the internal space of the cover body 100 to discharge smoke. The smoke pipe assembly 200 can be a plastic pipe or a metal pipe, one end of which can be inserted into the connector 102, or can be connected to the connector 102 by welding. The other end of the smoke pipe assembly 200 can be connected to a smoke collecting tank or a smoke collecting box. In this way, the smoke in the cover body 100 can be led out and collected through the smoke pipe assembly 200, so as to achieve centralized treatment of the smoke and prevent toxic gases from entering the air and endangering human health. The adjustment member 300 can be a plate-shaped member, which is movably arranged on the cover body 100. The operator can adjust the position of the adjustment member 300 according to actual needs to adjust the opening and closing degree of the air supply window 101, so that the inside of the cover body 100 is in a slightly negative pressure during the smoke exhaust operation, which is convenient for the suction and discharge of smoke; at the same time, it can also ensure that the oxygen entering from the air supply window 101 can meet the combustion of the flame in the cover body 100. The seal 400 may be a heat-insulating soft gasket, which is arranged on the periphery of the opening of the cover body 100. When the cover body 100 is assembled on the furnace body 10, the other side of the seal 400 presses against the top opening of the furnace body 10 to achieve sealing at the connection between the cover body 100 and the furnace body 10. In this way, a closed chamber can be formed between the furnace body 10 and the cover body 100, and the smoke can be effectively discharged only by a smaller fan suction force, which solves the problem that the smoke cannot be effectively discharged due to too small suction force at the rear of the smoke hood, and saves energy and reduces emissions.

[0032] In one example, an upper groove is provided above the seal 400, and the open end of the cover 100 can be inserted into the upper groove to achieve a tight connection between the seal 400 and the cover 100. A lower groove is provided below the seal 400, and the top open end of the furnace body 10 is inserted into the lower groove to achieve a tight connection between the seal 400 and the furnace body 10. Of course, in other embodiments, the seal 400 can also be connected between the cover 100 and the furnace body 10 by adhesive or the like.

[0033] In one example, a sealing ring is provided on the periphery of the adjusting member 300 so that when the adjusting member 300 is closed, the cover body 100 can form a relatively closed space, further enhancing the sealing performance of the cover body 100, improving the suction effect of the fan, and improving the smoke exhaust effect.

[0034] In a possible implementation manner, a sliding groove (not shown in the figure) is provided on the cover body 100 , and the sliding groove is located at the periphery of the air replenishing window 101 , and the adjusting member 300 is slidably connected to the cover body 100 via the sliding groove.

[0035] In this embodiment, the specific connection mode of the cover body 100 and the adjusting member 300 is optimized. Specifically, in order to simplify the structure, a sliding groove is provided at the periphery of the air replenishment window 101, and the adjusting member 300 is slidably embedded in the sliding groove, and is movably connected with the cover body 100 through the sliding groove to achieve the adjustment of the opening and closing degree of the air replenishment window 101. For example, the sliding groove can be provided on the cover body 100 on the upper and lower sides of the air replenishment window 101, and at this time, a receiving groove for receiving the adjusting member 300 is provided on the left or right side of the air replenishment window 101, so as to achieve the left and right sliding of the adjusting member 300 and the left and right opening and closing of the air replenishment window 101; or, the sliding groove is provided on the cover body 100 on the left and right sides of the air replenishment window 101, and at this time, a receiving groove for receiving the adjusting member 300 is provided on the upper or lower side of the air replenishment window 101, so as to achieve the up and down sliding of the adjusting member 300 and the up and down opening and closing of the air replenishment window 101.

[0036] Of course, in other embodiments, the sliding groove can also be provided on the outer wall of the cover body 100, in which case a sliding protrusion is provided on the inner side of the adjusting member 300, and the sliding protrusion is embedded in the sliding groove, so that the sliding connection between the adjusting member 300 and the cover body 100 is realized through the sliding cooperation between the sliding protrusion and the sliding groove. The specific connection method between the adjusting member 300 and the cover body 100 is not limited here, as long as the adjusting member 300 is slidably connected to the cover body 100.

[0037] In a possible embodiment, the cover body 100 includes two first side panels 110 arranged opposite to each other, two second side panels 120 arranged opposite to each other and a top panel 130, the first side panels 110 and the second side panels 120 are flat panels, the top panel 130 is a curved panel, and the two first side panels 110, the two second side panels 120 and the top panel 130 enclose a U-shaped cover body 100.

[0038] In this embodiment, the specific configuration of the cover body 100 is optimized. Specifically, the cover body 100 is configured as a composite component including at least two first side panels 110, two second side panels 120 arranged opposite to each other, and a top panel 130. The first side panels 110 and the second side panels 120 can be flat steel plates, and the top panel 130 can be a curved steel plate. The first side panels 110, the second side panels 120, and the top panel 130 can be formed by welding, or can be integrally formed by mold casting. The top panel 130 is recessed in the direction away from the furnace body 10 to increase the distance between the top of the cover body 100 and the insulation material 11 in the furnace body 10, so as to avoid the insulation material 11 on the top of the furnace body 10 directly contacting the top panel 130 after being heated and becoming high, thereby improving the safety of the operation; at the same time, the arc-shaped top panel 130 can form a higher space inside the cover body 100, so that the cover body 100 can be applied to insulation materials 11 of different heights, thereby improving the scope of application of the smoke collection assembly.

[0039] In one example, the first side plate 110 is a rectangular long plate, the second side plate 120 is an arc-shaped flat plate, and the top plate 130 is an arc-shaped curved plate. The first side plate 110 is connected to the long side of the top plate 130, and the second side plate 120 is arranged on the short side of the top plate 130. The connection between the second side plate 120 and the top plate 130 is a curved edge, and its curvature is the same as the arc curvature on the top plate 130. In this way, the processing difficulty of the top plate 130 is reduced, and the production cost is reduced.

[0040] In a possible implementation manner, the connector 102 is disposed on the top plate 130 , and the air supply window 101 is disposed on the first side plate 110 or the second side plate 120 .

[0041] In this embodiment, due to the rule that hot smoke will rise upward, the connector 102 is arranged on the top plate 130, which can improve the smoke exhaust effect and prevent smoke from accumulating on the top of the cover body 100. The air supply window 101 is arranged on the side of the first side plate 110 or the second side plate 120 close to the furnace body 10, and the air supply window 101 can be used to provide sufficient oxygen to the flame in the furnace body 10. At the same time, the air supply window 101 can also be used to cooperate with the cover body 100, the smoke exhaust component and the sealing member 400 to form a slight negative pressure in the internal space of the cover body 100, so that the smoke can be discharged from the cover body 100 under a relatively small fan power, thereby ensuring the smoke exhaust effect.

[0042] In a possible implementation, the smoke pipe assembly 200 includes a main smoke pipe 210 and a connecting smoke pipe 220 , and the main smoke pipe 210 is connected to the connector 102 via the connecting smoke pipe 220 .

[0043] In this embodiment, the specific configuration of the smoke tube assembly 200 is optimized. Specifically, the smoke tube assembly 200 is configured as a combined component including at least a main smoke tube 210 and a connecting smoke tube 220. The main smoke tube 210 can be a cylindrical tube body with a larger size, which can be connected with multiple connecting smoke tubes 220 to collect the smoke generated by multiple graphitization furnaces at the same time. The connecting smoke tube 220 can be a bent cylindrical tube body with a smaller size, and its two ends are respectively connected with the main smoke tube 210 and the connector 102, so as to send the smoke gathered in the cover body 100 into the internal channel of the main smoke tube 210 through the connector 102 and the internal channel of the connecting smoke tube 220, so as to discharge the smoke in the cover body 100.

[0044] In a possible implementation, the connecting smoke pipe 220 includes a first tube body 221, a second tube body 222 and a third tube body 223 which are connected in sequence, the third tube body 223 extends in the same direction as the first tube body 221, the first tube body 221 is water-sealedly connected to the main smoke pipe 210, and the third tube body 223 is water-sealedly connected to the connector 102.

[0045] In this embodiment, the specific configuration of the connecting smoke pipe 220 is optimized. Specifically, the connecting smoke pipe 220 is configured as a composite component including at least a first tube body 221, a second tube body 222 and a third tube body 223. The first tube body 221 and the second tube body 222 can be connected by a two-way elbow, and the second tube body 222 and the third tube body 223 can also be connected by the two-way elbow. The sizes of the first tube body 221, the second tube body 222 and the third tube body 223 are comparable, and the first tube body 221 and the third tube body 223 are arranged on the same side of the second tube body 222 to form an inverted approximately U-shaped bent pipe. The free end of the first tube body 221 is plugged into the joint on the main smoke pipe 210 and forms a water seal with the joint to improve the sealing performance of the connection between the first tube body 221 and the main smoke pipe 210; the free end of the third tube body 223 is plugged into the connector 102 and forms a water seal with the connector 102 to improve the sealing performance of the connection between the third tube body 223 and the cover body 100. In this way, the sealing between the cover body 100 and the smoke pipe assembly 200 can be improved through the water seal connection, which is conducive to forming a slight negative pressure inside the cover body 100 during smoke exhaust and improving the smoke exhaust effect.

[0046] In a possible implementation manner, a pressure relief member 500 is further included, and the pressure relief member 500 is disposed on the cover body 100 .

[0047] In this embodiment, the specific configuration of the smoke collecting assembly is further optimized. Specifically, the smoke collecting assembly is configured as a composite component including at least a cover body 100, a smoke pipe assembly 200, an adjusting member 300, a sealing member 400 and a pressure relief member 500. The pressure relief member 500 may be a pressure bursting disc, which may be arranged on the top of the cover body 100. When abnormal furnace spraying or material leakage occurs in the furnace body 10, the internal gas with excessive pressure in the cover may be depressurized to avoid the danger of explosion caused by pressure bidding, thereby improving the operation safety of the graphitization furnace.

[0048] In one example, at least two pressure relief members 500 may be provided, and the two pressure relief members 500 are respectively connected to the housing 100 and can operate independently, so that the pressure relief speed can be increased at least in terms of quantity, and the pressure relief efficiency can be improved.

[0049] In a possible implementation manner, a heat insulating member 600 is further included, and the heat insulating member 600 covers the inner side of the cover body 100 .

[0050] In this embodiment, the specific configuration of the smoke collecting assembly is further optimized. Specifically, the smoke collecting assembly is configured as a composite component including at least a cover body 100, a smoke pipe assembly 200, an adjusting member 300, a sealing member 400 and a heat insulating member 600. The heat insulating member 600 may be a ceramic fiberboard, which may be connected to the inner wall of the cover body 100 by bonding or the like. The appearance of the heat insulating member 600 is similar to that of the cover body 100 so as to be well accommodated by the cover body 100. The heat insulating member 600 has the function of heat insulation and heat preservation, which can ensure that the cover body 100 does not deform during long-term use, thereby extending the service life of the cover body 100.

[0051] In a possible embodiment, the thickness of the heat insulating member 600 is greater than the wall thickness of the cover 100; and / or, the sum of the thickness of the heat insulating member 600 and the wall thickness of the cover 100 is less than or equal to the wall thickness of the furnace body 10. In this way, the thickness of the heat insulating member 600 can be increased to increase the heat insulation effect of the cover 100, so that the cover 100 can still be used normally when the flame temperature in the furnace is high, and the cover 100 is ensured not to be deformed at a lower temperature, thereby extending the service life of the cover 100. At the same time, setting the overall thickness of the heat insulating member 600 and the cover 100 less than or equal to the wall thickness of the furnace body 10 can prevent the heat insulating member 600 from protruding from the inner wall of the furnace body 10 in the radial direction, avoid the formation of a negative angle at the connection between the furnace body 10 and the cover 100 / heat insulating member 600, and avoid the accumulation of smoke there and the generation of vortices, which affects the flow direction and collection of smoke.

[0052] In addition, if Figures 1 to 3The present application also provides a graphitization furnace, comprising a furnace body 10 and the above-mentioned smoke collecting assembly, wherein the cover body 100 of the smoke collecting assembly is connected to the top of the furnace body 10 through a seal 400.
