At present, the graphitization of negative electrode materials is generally carried out in Acheson furnaces or Acheson's improved furnaces or some box furnaces. Generally, it needs to go through the processes of feeding, graphitization treatment, cooling, and discharging. The graphitization treatment requires the raw material to be treated at a temperature of more than 2800° to change the physical properties of the raw material into graphite negative electrode material.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 3, a waste discharge mechanism of a graphitization furnace, comprising a furnace body 1, wherein the top of the furnace body 1 is connected to an exhaust pipe 2, the top of the exhaust pipe 2 is connected to a purification pipe 3, a filter screen plate 7 is provided at the upper end inside the exhaust pipe 2, the filter screen plate 7 is fixedly connected to the inner wall of the exhaust pipe 2, a fan-shaped block 14 is provided above the filter screen plate 7 and inside the purification pipe 3, a rotating rod 13 is penetrated inside the fan-shaped block 14, the rotating rod 13 is fixedly connected to the fan-shaped block 14, one end of the rotating rod 13 penetrates one of the side walls of the purification pipe 3 and is rotatably connected to the side wall, the fan-shaped block 14 is connected to a back-blowing mechanism 4, when the rotating rod 13 drives the fan-shaped block 14 to rotate, the back-blowing mechanism 4 is used to blow the powdered material at the bottom of the filter screen plate 7 into the furnace body 1, the The purification pipe 3 is provided with relatively distributed baffles 8, and vents 11 are provided inside the baffles 8. An arc-shaped mesh tube 9 is fixed between the baffles 8. The side walls of the baffles 8 and the side walls of the arc-shaped mesh tube 9 are slidably connected to the inner wall of the purification pipe 3. One of the baffles 8 is fixedly connected to the end of the rotating rod 13. A debris discharge port is provided below the arc-shaped mesh tube 9 and at the bottom of the purification pipe 3. A water tank 10 runs through the debris discharge port, and the top of the water tank 10 is adapted to the outer wall of the arc-shaped mesh tube 9. A fixing mechanism 5 is provided inside the debris discharge port, and the fixing mechanism 5 is used to fix the water tank 10. The water tank 10 is connected to a purification mechanism 6, and the purification mechanism 6 is used to purify the exhaust gas inside the arc-shaped mesh tube 9. An exhaust port 12 is provided on a side wall of the purification pipe 3 away from the rotating rod 13.

[0032] In this embodiment, the exhaust mechanism connects the exhaust pipe 2 with the furnace body 1, and the exhaust gas generated by the furnace body 1 enters the purification pipe 3 through the exhaust pipe 2, wherein a filter screen 7 is installed at the upper end of the exhaust pipe 2, and the filter screen 7 can filter the exhaust gas, and the exhaust gas directly passes through the filter screen 7 to enter the purification pipe 3, and the powdered materials entrained in the exhaust gas are filtered at the bottom of the filter screen 7, which can effectively prevent the powdered materials in the furnace body 1 from being discharged to the outside of the furnace body 1 along with the exhaust gas during use, thereby saving costs. After the exhaust gas enters the purification pipe 3, it will pass through the vent 11 inside one of the baffles 8 and enter the inner side of the arc-shaped mesh cylinder 9 At this time, the reaction solution in the water storage tank 10 is extracted into the arc-shaped mesh tube 9 through the purification mechanism 6, and harmful substances in the exhaust gas are removed by the reaction solution. For example, the exhaust gas discharged from the furnace body 1 contains sulfur dioxide, which can be removed by an alkaline solution at this time. The purified gas passes through the vent 11 inside the other baffle 8 into the purification pipe 3, and is finally discharged from the exhaust port 12 on the side wall of the purification pipe 3. The setting of the purification mechanism 6 can purify the exhaust gas discharged from the furnace body 1, thereby avoiding the influence of harmful substances discharged to the outside of the furnace body 1 on the external environment. The solid impurities such as salts generated by the reaction of the purification mechanism 6 with the exhaust gas will accumulate inside the arc-shaped mesh tube 9, and the arc-shaped The mesh tube 9 can filter solid impurities, thereby preventing the solid impurities generated by the reaction from entering the reaction solution inside the water tank 10 again, ensuring the reaction effect of the reaction solution and the exhaust gas. When there are too many solid impurities inside the arc-shaped mesh tube 9, the rotating rod 13 is rotated. The rotating rod 13 drives one of the baffles 8 to rotate on the one hand, and then drives the arc-shaped mesh tube 9 to rotate, thereby rotating the opening at the top of the arc-shaped mesh tube 9 to the bottom, and the solid impurities inside the arc-shaped mesh tube 9 fall from the inside of the arc-shaped mesh tube 9 and pass through the impurity discharge port at the bottom of the purification pipe 3 and fall into the water tank 10. At the same time, the fixing mechanism 5 no longer fixes the water tank 10, and the upper end of the water tank 10 moves to the outside of the impurity discharge port. At this time The staff can replace the reaction solution inside the water tank 10 and clean the solid impurities inside the water tank 10, which is convenient for the staff to clean the solid impurities inside the arc-shaped mesh tube 9, and can effectively prevent the solid impurities from accumulating inside the arc-shaped mesh tube 9. In addition, the rotating rod 13 also drives the fan-shaped block 14 to rotate while rotating. The fan-shaped block 14 drives the back-blowing mechanism 4 to operate while rotating. The back-blowing mechanism 4 blows air to the filter screen plate 7 from top to bottom, thereby blowing the powdered material at the bottom of the filter screen plate 7 into the furnace body 1, which can effectively prevent the poor ventilation caused by the accumulation of powdered material on the surface of the filter screen plate 7, and can also ensure the reuse of the powdered material, thereby solving the cost problem.

[0033] See also Figure 4 and Figure 5The back-blowing mechanism 4 includes a plurality of arc-shaped grooves 43 arranged inside the fan-shaped block 14 and distributed at equal intervals, one end of the arc-shaped groove 43 penetrates one of the side walls of the fan-shaped block 14, and a baffle 44 is slidably connected inside the arc-shaped groove 43, and the baffle 44 is fixedly connected to a first elastic member 45, and the other end of the first elastic member 45 is fixedly connected to the inner wall of the arc-shaped groove 43, and the side walls of the arc-shaped groove 43 are connected with air outlet holes 46, and one end of the air outlet hole 46 away from the arc-shaped groove 43 penetrates the arc-shaped side wall of the fan-shaped block 14, wherein an extrusion component is provided inside the purification pipeline 3, and when the rotating rod 13 drives the fan-shaped block 14 to rotate, the extrusion component is used to squeeze the baffle 44;

[0034] When the solid impurities inside the arc-shaped mesh cylinder 9 are cleaned, the rotating rod 13 is rotated. While the rotating rod 13 is rotating, the baffle 8 is driven to rotate on the one hand, and the fan-shaped block 14 is driven to rotate on the other hand. While the fan-shaped block 14 is rotating, the extrusion component inside the purification pipe 3 will squeeze the baffle 44 inside the arc-shaped groove 43. As the extrusion component squeezes the baffle 44, the baffle 44 squeezes the gas inside the arc-shaped groove 43, and the gas inside the arc-shaped groove 43 is discharged from the air outlet 46. As the fan-shaped block 14 rotates, the gas discharged from the air outlet 46 will pass through the surface of the filter screen plate 7, thereby blowing the powdery material at the bottom of the filter screen plate 7 into the furnace body 1, thereby preventing the powdery material from accumulating at the bottom of the filter screen plate 7. When the impurities inside the filtering arc-shaped mesh cylinder 9 are cleaned, the rotating rod 13 is rotated in the opposite direction. At this time, the squeezing degree of the baffle 44 by the extrusion component is reduced, and the baffle 44 automatically resets under the action of the first elastic member 45, wherein the first elastic member 45 can be a spring.

[0035] See also Figure 4 The extrusion assembly includes a connecting plate 41 fixedly connected to the inner wall of the purification pipe 3, and a plurality of arc-shaped rods 42 are fixed to the outside of the connecting plate 41, which are equidistantly distributed and correspond to the arc-shaped grooves 43 one by one. When the rotating rod 13 drives the fan-shaped block 14 to rotate, the arc-shaped rod 42 can extend into the arc-shaped groove 43 and squeeze the block 44;

[0036] When the solid impurities inside the arc-shaped mesh cylinder 9 are cleaned, the rotating rod 13 rotates and drives the fan-shaped block 14 to rotate. When the fan-shaped block 14 rotates to a certain extent, the arc-shaped rod 42 fixed on the outside of the connecting plate 41 will extend into the arc-shaped groove 43. As the fan-shaped block 14 continues to rotate, the arc-shaped rod 42 will continue to squeeze the baffle 44 inside the arc-shaped groove 43. The baffle 44 continuously squeezes the gas inside the arc-shaped groove 43, so that the gas discharged from the air outlet 46 can pass through the surface of the filter screen plate 7, thereby back-blowing the filter screen plate 7, wherein the outer diameter of the arc-shaped rod 42 is adapted to the inner diameter of the arc-shaped groove 43, so that the arc-shaped rod 42 can block one end of the arc-shaped groove 43 that passes through the fan-shaped block 14 during the process of squeezing the baffle 44, thereby avoiding the phenomenon that the gas discharged from the air outlet 46 enters the arc-shaped groove 43 due to the suction force generated inside the arc-shaped groove 43, and further improving the back-blowing effect on the filter screen plate 7.

[0037] In another embodiment, see Figure 5 The radius of the sector-shaped stopper 14 is smaller than the radius of the purification pipe 3, and the edge position of the arc surface of the sector-shaped stopper 14 is fixed with a symmetrically distributed arc-shaped stopper 15, and the arc surface of the arc-shaped stopper 15 is slidably connected to the inner wall of the purification pipe 3;

[0038] In this embodiment, the radius of the sector-shaped block 14 is set to be smaller than the radius of the purification pipe 3, so that the outer wall of the sector-shaped block 14 does not contact the inner wall of the purification pipe 3 when it rotates, thereby ensuring that the gas inside the arc groove 43 can be smoothly discharged from the air outlet 46.

[0039] See also Figure 3 , Figure 6 and Figure 8 The fixing mechanism 5 includes grooves arranged on the inner wall of the impurity discharge port and symmetrically distributed, and blocks 52 are slidably connected inside the grooves. The side wall of the water storage tank 10 is provided with grooves 51 which are symmetrically distributed and adapted to the blocks 52. One end of the block 52 is located inside the groove 51, and the other end is fixed with a second elastic member 53. The end of the second elastic member 53 away from the block 52 is fixedly connected to the inner wall of the groove, wherein the block 52 is connected to a traction assembly, and the traction assembly is used to pull the block 52 to the outside of the groove 51;

[0040] When purifying the exhaust gas discharged from the furnace body 1, the top of the water tank 10 is connected to the inside of the impurity discharge port. In order to facilitate the access of the water tank 10, the bottom of the block 52 close to the end of the water tank 10 has an inclined surface, which makes the water tank 10 squeeze the inclined surface of the block 52 during the access process. When the top of the water tank 10 fits with the bottom of the arc-shaped mesh tube 9, the block 52 is aligned with the slot 51, and the block 52 automatically enters the slot 51 under the action of the second elastic member 53. The second elastic member 53 can be a spring, which supports the water tank 10 through the plane on the top of the block 52. The stability of the water tank 10 can be effectively improved. When the reaction solution inside the water tank 10 needs to be replaced, the baffle plate 8 is driven to rotate by the rotating rod 13. While the baffle plate 8 rotates, it drives the arc-shaped mesh tube 9 to rotate, thereby pouring the solid impurities inside the arc-shaped mesh tube 9 into the water tank 10. On the other hand, the block 52 is pulled to the outside of the slot 51 by the traction component. Without the limit of the block 52, the water tank 10 can be drawn out from the impurity discharge port, which is convenient for the staff to replace the reaction solution inside the water tank 10 and clean the solid impurities inside the arc-shaped mesh tube 9.

[0041] See also Figure 8 The traction assembly includes a slide bar 58 that passes through the bottom of the purification pipe 3, a connecting block 55 is fixedly connected to the bottom of the slide bar 58, a traction rope 54 is fixed to the top of the connecting block 55, a guide groove is provided on a side wall of the groove away from the block 52, the guide groove passes through the bottom of the purification pipe 3, the traction rope 54 passes through the inside of the guide groove and is fixedly connected to the block 52, wherein a pushing component is provided inside the purification pipe 3, and the pushing component is used to push the slide bar 58 downward;

[0042] When the reaction solution inside the water tank 10 needs to be replaced, the baffle 8 is driven to rotate by the rotating rod 13. While the baffle rotates, the sliding rod 58 is pushed downward by the pushing component. The sliding rod 58 drives the connecting block 55 to move downward. Under the guidance of the guide groove, the connecting block 55 moves downward and pulls the clamping block 52 through the traction rope 54, thereby pulling the clamping block 52 to the outside of the clamping slot 51, making it convenient for the staff to pull the water tank 10 out of the discharge port.

[0043] See also Figure 6 and Figure 8 The pushing component includes a push plate 56 fixedly connected to the top of a push rod 59, a third elastic member 57 is fixed to the bottom of the push plate 56, and the lower end of the third elastic member 57 is fixedly connected to the bottom of the purification pipe 3, and a push rod 59 capable of squeezing the push plate 56 is fixed on the outer wall of the baffle 8;

[0044] When the reaction solution in the water storage tank 10 needs to be replaced, the baffle plate 8 is driven to rotate by the rotating rod 13. When the baffle plate 8 rotates, the push rod 59 on the side wall of the baffle plate 8 will make a circular motion. When the baffle plate 8 rotates to a certain extent, the push rod 59 on the side wall of the baffle plate 8 will contact the push plate 56. As the baffle plate 8 continues to rotate, the push rod 59 will squeeze the push plate 56, so that the push rod 59 drives the connecting block 55 to move downward through the sliding rod 58, and then the card block 52 is pulled to the outside of the card slot 51 through the traction rope 54. When the reaction solution in the water storage tank 10 is replaced, the rotating rod 13 drives the baffle plate 8 to rotate in the opposite direction, and the push rod 59 no longer squeezes the push plate 56. The push plate 56 automatically resets under the action of the third elastic member 57. The third elastic member 57 can be a spring. The push rod 59 drives the connecting block 55 to automatically reset through the sliding rod 58. The connecting block 55 no longer pulls the card block 52 through the traction rope 54, so that the card block 52 can enter the card slot 51 again.

[0045] See also Figure 2 and Figure 6 The purification mechanism 6 includes brackets 68 arranged on both sides of the water tank 10 and symmetrically distributed, one of the brackets 68 is fixed with a connecting column 610, and the other end of the connecting column 610 is rotatably connected to the water tank 10, and a hollow tube 69 is penetrated inside the other bracket 68, and the hollow tube 69 penetrates the side wall of the water tank 10 and is connected to the water tank 10. A water pump 64 is fixed on the inner wall of the purification pipeline 3, and the water pump 64 is connected to a water inlet pipe 65 and a water outlet pipe 63, and the water inlet pipe 65 is connected to the hollow tube 69. The water outlet pipe 63 penetrates one of the baffles 8 and extends to the inside of the arc-shaped net tube 9, and a branch pipe 62 is fixed to one end of the water outlet pipe 63 located inside the arc-shaped net tube 9, and a nozzle 61 is fixed to the top of the branch pipe 62;

[0046] When treating the exhaust gas, start the water pump 64. Under the action of the water pump 64, the reaction solution inside the water tank 10 enters the water inlet pipe 65 through the hollow tube 69, then enters the branch pipe 62 through the outlet pipe 63, and is finally sprayed out from the nozzle 61 to react with the harmful substances in the exhaust gas. The branch pipe 62, the outlet pipe 63 and the hollow tube 69 can all be stainless steel pipes, the water inlet pipe 65 can be a hose, and the connection column 610 and the hollow tube 69 are rotatably connected to the water tank 10 so that the water tank 10 can be flipped downward after moving to the outside of the impurity discharge port, which is convenient for the staff to pour out the solid impurities and reaction solution inside the water tank 10.

[0047] See also Figure 6 The top of the bracket 68 is fixed with a fourth elastic member 67 and a guide rod 66. The upper end of the fourth elastic member 67 is fixedly connected to the outer bottom of the purification pipe 3. The guide rod 66 penetrates the bottom of the purification pipe 3 and is slidably connected to the bottom of the purification pipe 3.

[0048] The bracket 68 is limited by the guide rod 66 and buffered by the fourth elastic member 67, which can effectively improve the stability of the water storage tank 10 during installation and disassembly, wherein the fourth elastic member 67 can be a spring.

[0049] See also Figure 7 A positioning plate 16 is fixed to the outside of the rotating rod 13, and a positioning pin 17 is passed through the inside of the positioning plate 16, wherein a positioning groove 19 adapted to the positioning pin 17 is provided on the outer wall of the purification pipe 3, and one end of the positioning pin 17 is connected to the positioning plate 16 through a fifth elastic member, and the other end of the positioning pin 17 is located inside the positioning groove 19;

[0050] When removing harmful substances from the exhaust gas, the end of the positioning pin 17 is located inside the positioning groove 19 on the outer wall of the purification pipe 3 under the action of the fifth elastic member 18. The fifth elastic member 18 can be a spring. The positioning groove 19 fixes the rotating rod 13 through the positioning pin 17 and the positioning plate 16, effectively improving the stability of the rotating rod 13, thereby ensuring the stability of the fan-shaped block 14, the baffle 8 and the arc-shaped mesh tube 9. When the rotating rod 13 needs to be rotated, the positioning pin 17 can be pulled out from the positioning groove 19.

[0051] Working principle: When the exhaust mechanism is in use, the exhaust gas generated by the furnace body 1 enters the interior of the purification pipe 3 through the exhaust pipe 2, wherein a filter screen 7 is installed at the upper end of the exhaust pipe 2, and the filter screen 7 can filter the exhaust gas, and the exhaust gas directly passes through the filter screen 7 to enter the interior of the purification pipe 3, while the powdery materials entrained in the exhaust gas are filtered at the bottom of the filter screen 7, which can effectively prevent the powdery materials in the furnace body 1 from being discharged to the outside of the furnace body 1 along with the exhaust gas during the use of the furnace body 1, thereby saving costs. After the exhaust gas enters the interior of the purification pipe 3, it will pass through the vent 11 inside one of the baffles 8 and enter the inner side of the arc-shaped mesh cylinder 9. At this time, under the action of the water pump 64, the reaction solution in the water storage tank 10 enters through the hollow tube 69 Enters into the water inlet pipe 65, and then enters into the branch pipe 62 through the water outlet pipe 63. The reaction solution is sprayed out from the nozzle 61 and reacts with harmful substances in the exhaust gas. The harmful substances in the exhaust gas are removed by the reaction solution. The purified gas passes through the vent 11 inside the other baffle 8 into the purification pipe 3, and is finally discharged from the exhaust port 12 on the side wall of the purification pipe 3. It can effectively avoid the harmful substances in the exhaust gas from being discharged to the outside of the furnace body 1 and affecting the external environment. The solid impurities such as salts generated by the reaction will accumulate inside the arc-shaped mesh tube 9. The arc-shaped mesh tube 9 can filter the solid impurities, thereby preventing the solid impurities generated by the reaction from entering the reaction solution inside the water storage tank 10 again, thereby ensuring the reaction effect of the reaction solution and the exhaust gas.

[0052] When there are too many solid impurities in the arc-shaped net cylinder 9, the rotating rod 13 is rotated, and the rotating rod 13 drives one of the baffles 8 to rotate. On the one hand, the baffle 8 drives the arc-shaped net cylinder 9 to rotate. When the opening at the top of the arc-shaped net cylinder 9 rotates to the bottom, the solid impurities in the arc-shaped net cylinder 9 fall from the inside of the arc-shaped net cylinder 9 and pass through the impurity discharge port at the bottom of the purification pipeline 3 and fall into the water storage tank 10. On the other hand, the baffle 8 drives the push rod 59 on its side wall to do a circular motion. When the baffle 8 rotates to a certain extent, the push rod 59 on the side wall of the baffle 8 The push rod 59 will contact the push plate 56. As the baffle plate 8 continues to rotate, the push rod 59 will squeeze the push plate 56, so that the push rod 59 drives the connecting block 55 to move downward through the sliding rod 58. The connecting block 55 pulls the clamping block 52 through the traction rope 54, so that the clamping block 52 is pulled to the outside of the clamping groove 51. Without the limit of the clamping block 52, the water storage tank 10 can be drawn out from the impurity discharge port, which is convenient for the staff to replace the reaction solution in the water storage tank 10 and clean the solid impurities in the arc-shaped mesh cylinder 9.

[0053] In addition, the rotation of the rotating rod 13 also drives the fan-shaped block 14 to rotate. When the fan-shaped block 14 rotates to a certain extent, the arc rod 42 fixed on the outside of the connecting plate 41 will extend into the arc groove 43. As the fan-shaped block 14 continues to rotate, the arc rod 42 will continue to squeeze the baffle 44 inside the arc groove 43. The baffle 44 continuously squeezes the gas inside the arc groove 43, and the gas inside the arc groove 43 is discharged from the air outlet 46. As the fan-shaped block 14 rotates, the gas discharged from the air outlet 46 will pass through the surface of the filter screen plate 7, thereby blowing the powdered material at the bottom of the filter screen plate 7 into the interior of the furnace body 1, thereby avoiding the accumulation of powdered material at the bottom of the filter screen plate 7, which can effectively avoid the phenomenon of poor ventilation caused by the accumulation of powdered material on the surface of the filter screen plate 7, and can also ensure the reuse of the powdered material, thereby solving the cost problem.
