Description

Technical Field

[0001] This invention belongs to the field of furnace cooling, specifically relating to a temperature control device for graphite anode materials. Background Technology

[0002] Currently, during the production process of graphite anode materials, it is usually necessary to perform temperature control on powdered or granular materials, and after heating, the furnace body and the furnace charge inside the furnace need to be cooled.

[0003] Patent publication number CN217929807U relates to a temperature control device for graphite anode materials, including a temperature control box. Support legs are located at the bottom of the temperature control box, specifically at its four corners. An installation groove is provided inside the temperature control box. A gear-driven cooling mechanism is located on the upper side of the temperature control box, and a sintering box is located below the cooling mechanism. Heating is achieved through a heater. A second motor drives a stirrer to rotate, stirring the anode material and increasing its heating area. A first motor drives a drive wheel, which meshes with a bevel gear, thereby rotating a threaded rod. This causes a drainer to move horizontally within a sliding groove. A retractable corrugated pipe above the drainer moves horizontally with it, distributing water through a nozzle to cool the sintering box. A temperature sensor is installed inside the sintering box to monitor the internal temperature, allowing the user to adjust the temperature accordingly.

[0004] In the existing technology, fine graphite particles can easily flow back into the exhaust pipe and adhere to and accumulate on the surface of the inner furnace body to form an insulating layer, which reduces the cooling efficiency of the inner furnace body. In addition, the accumulation of blocky negative electrode material on the right side of the air inlet pipe will cause the ventilation cross-sectional area to be too small and the air volume to drop significantly, thereby reducing the circulation efficiency. At the same time, condensation water forms on the top of the preheating box and drips onto the surface of the negative electrode material, causing the negative electrode material to become damp and affecting the preheating uniformity. Summary of the Invention

[0005] The purpose of this application is to provide a temperature control device for graphite anode materials, which aims to solve the problem of preventing fine graphite particles from easily flowing back into the exhaust pipe and adhering and accumulating on the surface of the inner furnace body to form an insulating layer, thereby reducing the cooling efficiency of the inner furnace body.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This application provides a temperature control device for graphite anode materials, including an outer furnace body and a temperature control component. An inner furnace body is disposed inside the outer furnace body. A discharge hole is opened at the bottom of the inner furnace body, and a preheating box is disposed at the top of the outer furnace body. A feed pipe is disposed between the preheating box and the inner furnace body. The temperature control component includes a cooling device, an exhaust pipe, an air inlet pipe, a feed hole, a rotating rod, a rotating frame, a sealing plate, a shielding cylinder, a square hole, a limiting frame, and a limiting spring. The cooling device is fixedly installed on the left side of the circumferential surface of the outer furnace body. The exhaust pipe is disposed between the outer furnace body and the preheating box. The air inlet pipe is disposed between the preheating box and the cooling device. The feed hole is opened at the top of the preheating box. The rotating rod is rotatably installed at the bottom of the inner wall of the preheating box. The rotating frame is fixedly installed on the circumferential surface of the rotating rod. The sealing plate is fixedly installed at the top of the rotating frame. The shielding cylinder is slidably installed on the inner wall of the exhaust pipe. The square hole is opened on the circumferential surface of the shielding cylinder. The limiting frame is fixedly installed on the left side of the shielding cylinder. The limiting spring is disposed between the limiting frame and the preheating box. In this way, the square hole is exposed on the outside of the exhaust pipe, thus releasing the seal on the exhaust pipe. After the seal on the exhaust pipe is released, the hot air inside the exhaust pipe can enter the preheating box to preheat the negative electrode material.

[0007] In some embodiments, an electric valve is provided between the feed pipe and the preheating box, filter plates are provided inside both the air inlet pipe and the exhaust pipe, and the sealing plate is in contact with the top of the inner wall of the preheating box; In this way, the rotating frame can no longer rotate counterclockwise, causing the sealing plate to stop at the bottom of the feed hole, thus blocking and sealing the feed hole.

[0008] In some embodiments, the diameter of the sealing plate is larger than the diameter of the feed hole. This ensures the stability of the seal between the sealing plate and the feed hole. The shielding cylinder is used to shield the exhaust pipe. The limiting frame is used to limit the rotation frame and the sealing plate. The shielding cylinder moves to the left under the pressure of hot air. The leftward movement of the shielding cylinder causes the square hole to protrude outside the exhaust pipe, thereby releasing the seal on the exhaust pipe. A valve is provided between the outer furnace body and the exhaust pipe.

[0009] In some embodiments, the device further includes a feeding assembly and a moisture-proof assembly. The feeding assembly is used to accelerate the feeding speed of the negative electrode material, and the moisture-proof assembly is used to reduce the mixing of condensate into the interior of the negative electrode material. The feeding assembly includes a feeding plate, a screen frame, a screen plate, an arc panel, and a screen spring. The feeding plate is fixedly installed on the circumferential surface of the rotating rod. The screen frame is fixedly installed on the inner wall of the preheating box. The screen plate is slidably installed on the inner wall of the screen frame. The arc panel is fixedly installed on the right side of the screen plate. The screen spring is disposed between the screen frame and the screen plate. In this way, the rotating rod will drive the pusher plate to rotate, and the rotation of the pusher plate will flip the negative electrode material at the bottom of the preheating box.

[0010] In some embodiments, the end of the pusher plate away from the rotating rod is set as an inclined surface. Setting the end of the pusher plate away from the rotating rod as an inclined surface can reduce the frictional force when the pusher plate contacts the arc panel. The screen frame contacts the air inlet pipe. Both the screen frame and the screen plate are provided with screen holes. The screen plate moves to the right and resets under the elastic force of the screen hole spring. The reciprocating horizontal movement of the screen plate pushes the blocky negative electrode material on the right side of the air inlet pipe.

[0011] In some embodiments, the moisture-proof assembly includes a wiping frame, a connector, a placement plate, a placement hole, a sponge block, a placement groove, and a rubber sheet. The wiping frame is fixedly installed on the front side of the rotating frame, the connector is disposed between the wiping frame and the rotating frame, the placement plate is fixedly installed on the inner wall of the wiping frame, the placement hole is opened on the top of the placement plate, the sponge block is disposed on the top of the placement plate, the placement groove is opened on the top of the inner wall of the preheating box, and the rubber sheet is fixedly installed on the top of the inner wall of the placement groove. In this way, the rotation of the placement plate will cause the sponge block to rotate, and the rotating sponge block will continue to contact the top of the inner wall of the preheating box, wiping away the condensate on the top of the inner wall of the preheating box.

[0012] In some embodiments, the top of the wiping frame is provided with an anti-collision groove, which is used to prevent the wiping frame from interfering with the movement of the rubber plate. The sponge block contacts the top of the inner wall of the preheating box. The sponge block deforms and squeezes out the condensate it has absorbed. The condensate squeezed out by the sponge block flows into the bottom of the inner wall of the wiping frame through the placement hole under its own gravity.

[0013] In some embodiments, the rubber plate is elastic, which can prevent the rubber plate from interfering with the sealing plate. The sponge block is used to wipe away condensate, and the rubber plate is used to squeeze the sponge block. The maintenance personnel will regularly disassemble the top cover and the box to clean and maintain the inside of the preheating box. The wiping frame is fixedly connected to the rotating frame through a connector.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, the hot air inside the exhaust pipe can enter the preheating box to preheat the negative electrode material. The hot air is recovered and enters the preheating box to preheat the waste heat of the negative electrode material, which can realize the recycling of heat energy, thereby reducing energy consumption and improving circulation efficiency. The sealing plate stops at the bottom of the feed hole to block and seal the feed hole. The movement of the blocking cylinder synchronously drives the limiting frame to limit the rotation frame, so that the sealing plate automatically stops and seals the feed hole, thereby ensuring that the preheating process is fully enclosed and avoids heat loss. The square hole is exposed on the outside of the exhaust pipe to release the seal on the exhaust pipe. By releasing the seal on the exhaust pipe only during preheating, the backflow of negative electrode material into the exhaust pipe can be reduced, thereby preventing fine graphite particles from flowing back into the exhaust pipe and adhering and accumulating on the surface of the inner furnace body to form an isolation layer, thereby improving the cooling efficiency of the inner furnace body.

[0016] 2. In this invention, the rotating pusher plate flips the negative electrode material at the bottom of the preheating box. The flipping of the negative electrode material by the pusher plate can prevent the negative electrode material from piling up at the top of the feed pipe. The pusher plate rotates synchronously with the rotating rod, continuously flipping the negative electrode material at the bottom of the preheating box, which can prevent the negative electrode material from piling up at the top of the feed pipe and prevent material jamming or blockage.

[0017] 3. In this invention, the reciprocating horizontal movement of the perforated plate pushes the blocky negative electrode material on the right side of the air inlet pipe, thereby preventing the blocky negative electrode material from accumulating on the right side of the air inlet pipe. Through the cooperation of the pusher plate and the arc plate, the perforated plate is driven to move left and right to disperse the blocky negative electrode material, preventing it from accumulating and blocking the right side of the air inlet pipe, thereby preventing the ventilation cross-sectional area from being too small.

[0018] 4. In this invention, the rotating sponge block continues to contact the top of the inner wall of the preheating box and wipes away the condensate on the top of the inner wall of the preheating box. By wiping the sponge block in sync with the rotation, the sponge block can continuously absorb the condensate on the top of the preheating box, thereby preventing the condensate from dripping and causing the negative electrode material to become damp.

[0019] 5. In this invention, the sponge block can squeeze out the condensate it has absorbed and continue to wipe and absorb the condensate on the top of the preheating box. The sponge block rotates and squeezes the rubber plate to achieve automatic dehydration. It can repeatedly absorb water and maintain a long-term high-efficiency water absorption state. In addition, the top cover of the preheating box and the wiping frame are removable, which facilitates regular maintenance and emptying of accumulated water. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1 - Figure 8As shown, one embodiment of the present invention is: a temperature control device for graphite anode materials, including an outer furnace body 1 and a temperature control component. An inner furnace body 2 is disposed inside the outer furnace body 1. A discharge hole 3 is opened at the bottom of the inner furnace body 2. A preheating box 4 is disposed at the top of the outer furnace body 1. A feed pipe 5 is disposed between the preheating box 4 and the inner furnace body 2. The temperature control component includes a cooling device 6, an exhaust pipe 7, an air inlet pipe 8, a feed hole 9, a rotating rod 10, a rotating frame 11, a sealing plate 12, a shielding cylinder 13, a square hole 14, a limiting frame 15, and a limiting spring 16. The cooling device 6 is fixedly installed on the left side of the circumferential surface of the outer furnace body 1. The exhaust pipe 7 is disposed between the outer furnace body 1 and the preheating box 4. The air inlet pipe 8 is disposed between the preheating box 4 and the cooling device 6. The feed hole 9 is opened at the top of the preheating box 4. Rod 10 is rotatably installed on the bottom of the inner wall of the preheating box 4. Rotating frame 11 is fixedly installed on the circumferential surface of rotating rod 10. Sealing plate 12 is fixedly installed on the top of rotating frame 11. Baffle cylinder 13 is slidably installed on the inner wall of exhaust pipe 7. Square hole 14 is opened on the circumferential surface of baffle cylinder 13. Limiting frame 15 is fixedly installed on the left side of baffle cylinder 13. Limiting spring 16 is set between limiting frame 15 and preheating box 4. Cooling gas is continuously injected into the bottom of inner furnace body 2 and outer furnace body 1 through cooling equipment 6, so that the gas pressure at the bottom of inner furnace body 2 and outer furnace body 1 continues to increase. The pressure inside exhaust pipe 7 increases, which can push baffle cylinder 13 to move to the left. The hot gas is recovered and enters preheating box 4 to preheat the waste heat of negative electrode material, which can realize the recycling of heat energy, thereby reducing energy consumption and improving recycling efficiency.

[0033] An electric valve is installed between the feed pipe 5 and the preheating box 4. Filter plates are installed inside both the air inlet pipe 8 and the exhaust pipe 7. The sealing plate 12 contacts the top of the inner wall of the preheating box 4. The rotating frame 11 cannot continue to rotate counterclockwise, causing the sealing plate 12 to stop at the bottom of the feed hole 9. The sealing plate 12 stops at the bottom of the feed hole 9, thus blocking and sealing the feed hole 9. The movement of the blocking cylinder 13 synchronously drives the limiting frame 15 to limit the rotating frame 11, so that the sealing plate 12 automatically stops and seals the feed hole 9, thereby ensuring that the preheating process is fully enclosed and avoids heat loss. When the limiting frame 15 locks the rotating frame 11, the motor stalls and triggers an overload automatic stop.

[0034] The diameter of the sealing plate 12 is larger than the diameter of the feed hole 9. The larger diameter of the sealing plate 12 than the feed hole 9 ensures the stability of the seal of the feed hole 9. The shielding cylinder 13 is used to shield the exhaust pipe 7. The limiting frame 15 is used to limit the rotation frame 11 and the sealing plate 12. The shielding cylinder 13 moves to the left under the pressure of hot air. The leftward movement of the shielding cylinder 13 will cause the square hole 14 to protrude outside the exhaust pipe 7. The square hole 14 protruding outside the exhaust pipe 7 will release the seal on the exhaust pipe 7. Releasing the seal on the exhaust pipe 7 only during preheating can reduce the backflow of negative electrode material into the exhaust pipe 7, thereby preventing fine graphite particles from backflowing into the exhaust pipe 7 and adhering and accumulating on the surface of the inner furnace body 2 to form an isolation layer, thereby improving the cooling efficiency of the inner furnace body 2. A valve is provided between the outer furnace body 1 and the exhaust pipe 7.

[0035] In this embodiment, the blocky negative electrode material is fed into the inner furnace body 2 through the preheating box 4 and the feeding pipe 5. The solenoid valve is operated to seal the inner furnace body 2. A heating device is installed at the bottom of the inner furnace body 2. A motor is installed at the top of the preheating box 4, and the motor is equipped with an overload self-stop device. The output end of the motor is fixedly connected to the rotating rod 10. When feeding, the motor will drive the rotating rod 10 to rotate counterclockwise. The rotation of the rotating rod 10 will drive the rotating frame 11 to rotate. The rotation of the rotating frame 11 will drive the sealing plate 12 to rotate continuously. The continuous rotation of the sealing plate 12 will intermittently block the feeding hole 9. When the negative electrode material is to be processed, the heating device is started to heat the negative electrode material inside the inner furnace body 2. After the negative electrode material is processed. The cooling device 6 is activated to fill the jacket between the outer furnace body 1 and the inner furnace body 2 with cold air, thereby cooling the inner furnace body 2. The cold air cools the inner furnace body 2 and carries away the heat of the inner furnace body 2, converting it into hot air. The hot air enters the exhaust pipe 7 and squeezes the shielding cylinder 13. The shielding cylinder 13 moves to the left due to the pressure of the hot air. The leftward movement of the shielding cylinder 13 causes the square hole 14 to protrude from the outside of the exhaust pipe 7, thereby releasing the seal on the exhaust pipe 7. After the seal on the exhaust pipe 7 is released, the hot air inside the exhaust pipe 7 can enter the preheating box 4 to preheat the negative electrode material. At the same time, the hot air inside the preheating box 4 can enter the cooling device 6 through the air inlet pipe 8 to complete the circulating cooling. Furthermore, the leftward movement of the shielding cylinder 13 will drive the limiting frame 15 to move to the left. The leftward movement of the limiting frame 15 will pull the limiting spring 16. The limiting spring 16 deforms and stores force due to the pull of the limiting frame 15. At the same time, the limiting frame 15 moves to the left and comes into contact with the rotating frame 11, limiting the rotating frame 11. The rotating frame 11 is limited by the limiting frame 15, preventing it from continuing to rotate counterclockwise. The inability of the rotating frame 11 to continue rotating counterclockwise causes the sealing plate 12 to stop at the bottom of the feed hole 9. The sealing plate 12 stops at the bottom of the feed hole 9, thus blocking and sealing the feed hole 9, so that the negative electrode material inside the preheating box 4 is in a sealed state during preheating.

[0036] Please see Figure 1 - Figure 8 Based on the above embodiments, another embodiment of the present invention further includes a pushing component and a moisture-proof component. The pushing component is used to accelerate the feeding speed of the negative electrode material, and the moisture-proof component is used to reduce the mixing of condensate into the interior of the negative electrode material. The pushing component includes a pushing plate 171, a screen frame 172, a screen plate 173, an arc panel 174, and a screen spring 175. The pushing plate 171 is fixedly installed on the circumferential surface of the rotating rod 10, the screen frame 172 is fixedly installed on the inner wall of the preheating box 4, the screen plate 173 is slidably installed on the inner wall of the screen frame 172, the arc panel 174 is fixedly installed on the right side of the screen plate 173, and the screen spring 175 is disposed between the screen frame 172 and the screen plate 173. The pushing plate 171 rotates synchronously with the rotating rod 10, continuously turning over the negative electrode material at the bottom of the preheating box 4, which can prevent the negative electrode material from accumulating on the top of the feed pipe 5 and prevent feeding jamming or blockage.

[0037] The end of the pusher plate 171 away from the rotating rod 10 is set as an inclined surface. Setting the end of the pusher plate 171 away from the rotating rod 10 as an inclined surface can reduce the friction when the pusher plate 171 contacts the arc panel 174. The screen frame 172 contacts the air inlet pipe 8. The screen frame 172 and the screen plate 173 are both provided with screen holes. The screen plate 173 moves to the right and resets under the elastic force of the screen spring 175. The reciprocating horizontal movement of the screen plate 173 pushes the blocky negative electrode material on the right side of the air inlet pipe 8. Through the cooperation of the pusher plate 171 and the arc panel 174, the screen plate 173 is driven to move left and right back and forth to push away the blocky negative electrode material, so as to avoid its accumulation and blockage of the right side of the air inlet pipe 8, thereby preventing the ventilation cross-sectional area from being too small.

[0038] The moisture-proof component includes a wiping frame 181, a connector 182, a placement plate 183, a placement hole 184, a sponge block 185, a placement groove 186, and a rubber plate 187. The wiping frame 181 is fixedly installed on the front side of the rotating frame 11. The connector 182 is located between the wiping frame 181 and the rotating frame 11. The placement plate 183 is fixedly installed on the inner wall of the wiping frame 181. The placement hole 184 is opened on the top of the placement plate 183. The sponge block 185 is located on the top of the placement plate 183. The placement groove 186 is opened on the top of the inner wall of the preheating box 4. The rubber plate 187 is fixedly installed on the top of the inner wall of the placement groove 186. By wiping synchronously with the sponge block 185, condensate on the top of the preheating box 4 can be continuously absorbed, thereby preventing condensate from dripping and causing the negative electrode material to become damp.

[0039] The top of the wiping frame 181 is provided with an anti-collision groove to prevent the wiping frame 181 from interfering with the movement of the rubber plate 187. The sponge block 185 contacts the top of the inner wall of the preheating box 4. The sponge block 185 deforms and squeezes out the condensate it has absorbed. The condensate squeezed out by the sponge block 185 flows into the bottom of the inner wall of the wiping frame 181 through the placement hole 184 under its own gravity. The sponge block 185 rotates and squeezes the rubber plate 187 to achieve automatic dehydration. It can repeatedly absorb water and maintain a long-term high-efficiency water absorption state.

[0040] The rubber plate 187 is elastic, which can prevent the rubber plate 187 from interfering with the sealing plate 12. The sponge block 185 is used to wipe the condensate. The rubber plate 187 is used to squeeze the sponge block 185. The sponge block 185 comes into contact with the rubber plate 187 during the movement and squeezes it. The maintenance personnel will regularly disassemble the top cover and the box to clean and maintain the inside of the preheating box 4. The wiping frame 181 is fixedly connected to the rotating frame 11 through the connector 182. The top cover of the preheating box 4 and the wiping frame 181 are detachable, which can facilitate regular maintenance and emptying of accumulated water.

[0041] In this embodiment, when the rotating rod 10 rotates, it will drive the pusher plate 171 to rotate. The rotation of the pusher plate 171 will turn over the negative electrode material at the bottom of the preheating box 4. The turning of the negative electrode material by the pusher plate 171 can prevent the negative electrode material from piling up at the top of the feed pipe 5 and causing the material to be stuck. In addition, the rotation of the pusher plate 171 will contact the arc surface of the arc panel 174 and squeeze the arc panel 174. The arc panel 174 will move to the left due to the squeezing of the pusher plate 171. The leftward movement of the arc panel 174 will drive the screen plate 173 to move to the left. The leftward movement of the screen plate 173 will squeeze the screen spring 175. The screen spring 175 will deform and store force due to the squeezing of the screen plate 173. As the pusher plate 171 continues to rotate, it will disengage from the arc panel 174. After the arc panel 174 disengages from the pusher plate 171, the screen plate 173 moves to the right and resets under the elastic force of the screen spring 175. The screen plate 173 moves horizontally back and forth to push the blocky negative electrode material on the right side of the air inlet pipe 8, thereby preventing the blocky negative electrode material from accumulating on the right side of the air inlet pipe 8 and causing the air inlet pipe 8 to enter slowly.

[0042] The counterclockwise rotation of the rotating frame 11 will cause the wiping frame 181 to rotate, the rotation of the wiping frame 181 will cause the placement plate 183 to rotate, the rotation of the placement plate 183 will cause the sponge block 185 to rotate, the rotation of the sponge block 185 will continue to contact the top of the inner wall of the preheating box 4 and wipe the condensate on the top of the inner wall of the preheating box 4. At the same time, the rotation of the sponge block 185 will contact the rubber plate 187 and squeeze the rubber plate 187. The sponge block 185 deforms under the reaction force of the squeezed rubber plate 187, and the deformation of the sponge block 185 squeezes out the condensate it has absorbed. The condensate squeezed out by the sponge block 185 flows into the bottom of the inner wall of the wiping frame 181 through the placement hole 184 under its own gravity. The sponge block 185 can continue to wipe and absorb the condensate on the top of the preheating box 4 after squeezing out the condensate it has absorbed. The preheating box 4 consists of a top cover and a box body. The top cover and the box body are fixedly connected by bolts and nuts. The maintenance personnel will regularly disassemble the top cover and the box body to clean and maintain the inside of the preheating box 4. The wiping frame 181 is fixedly connected to the rotating frame 11 through the connector 182. When the top cover and the box body are disassembled, the wiping frame 181 can be separated from the rotating frame 11 and the condensate collected at the bottom of the wiping frame 181 can be emptied.
