Description

Technical Field

[0001] The present invention relates to the technical field of graphite processing, and in particular to a purification device and method and application thereof in graphite processing. Background Art

[0002] Graphite purification is the process of introducing halogen gas, such as chlorine or halogenated hydrocarbons, into the graphite material at ultra-high temperature to react with it, converting the valuable metals in the graphite into chlorides and complexes in the gas or condensed phase with lower melting and boiling points. These chlorides and complexes are eventually separated from other components and escape. This allows the purity of the purified graphite to reach over 99.9%, thus meeting the demand for high-purity graphite in the domestic semiconductor, photovoltaic single crystal, new energy and other fields.

[0003] Chinese invention patent application number 202210368418.2 proposes a calcining device for graphite processing, including a calcining box, the top of which is respectively provided with a feed hopper and an outer shell, a motor is provided inside the outer shell, the output shaft of the motor is fixedly connected to a driving wheel, the driving wheel is connected to a driven wheel through a belt drive, the bottom of the driving wheel and the driven wheel are both fixedly connected to a rotating rod, the other end of the rotating rod is rotatably connected to the inner wall of the calcining box, a plurality of stirring rods are fixedly connected to the surface of the rotating rod, and a discharge channel is provided at the bottom of the left side of the calcining box; the present invention can stir and tumble the graphite during the calcination process to make the heating more uniform, and can also purify the flue gas generated by calcination, solving the problem that the current calcining device cannot calcine graphite evenly and cannot purify the generated flue gas.

[0004] However, in this existing technology, only basic stirring of the graphite can be performed, and the bottom graphite and the top graphite cannot be repeatedly replaced, and the graphite in the stirring center cannot be exchanged with the graphite outside, resulting in uneven heating of the graphite; during the calcination process, gas needs to be introduced to react with impurities in the graphite particles to generate compounds. In this technical solution, it is difficult for the gas to fully contact the graphite particles, resulting in slow separation of impurities in the graphite, affecting the calcination and purification of the graphite; during the stirring process, the graphite will collide with each other to produce graphite powder, which floats and mixes with the impurities, making the subsequent separation of the impurities more cumbersome and the graphite recovery troublesome.

[0024] Technical effects and advantages of the present invention:

[0025] 1. In the present invention, by providing a traction component and a flip plate, the traction component drives the flip plate to rotate in a circle, flipping the graphite particles at the bottom layer, causing the graphite particles at the top and bottom layers to tumble alternately, so that the graphite particles are evenly heated; at the same time, the gaps between the graphite particles are enlarged, facilitating better mixing of the graphite particles and the gas; and large graphite blocks formed by mutual adhesion can be squeezed and crushed; by providing a filter component, the graphite powder generated by the flipping and collision of the graphite particles is filtered and separated from the gas, thereby preventing the loss of graphite.

[0026] 2. In the present invention, a traction component is provided to drive the flip plate to perform circular motion, thereby driving the graphite particles at the bottom layer to continuously flip to the top layer, so that the graphite particles are continuously flipped in the longitudinal direction to ensure uniform heating; at the same time, the graphite particles can fully contact with the gas during the flipping and falling process, thereby accelerating the reaction of impurities; while the flip plate drives the graphite particles to rotate, the resistance generated by the graphite particles causes the flip plate to drive the prying components to move closer to each other, which can generate extrusion force on the agglomerated graphite particles and disperse them; thereby accelerating the purification efficiency of the graphite.

[0027] 3. In the present invention, a toggle plate is provided to disperse and evenly distribute the conical accumulation formed after the graphite particles are fed, thereby accelerating the uniform dispersion of the graphite particles in the lateral direction, and facilitating the subsequent uniform heating of the graphite particles. In addition, when the graphite particles are discharged, the toggle plate is used to assist in the discharge, and at the same time, by detecting whether the torsion spring is compressed, it is determined whether the current rotating plate is rotating, thereby detecting whether there are graphite particles at the current position of the toggle plate, and then determining whether the graphite is evenly dispersed or whether the graphite has been discharged.

[0028] 4. In the present invention, by setting a filter plate, when the gasified impurities inside the inner cylinder are extracted at the exhaust port, the graphite powder floating in the gasified impurities is filtered and separated, so as to prevent the subsequent impurity separation steps from being cumbersome. The ventilation volume of the filter plate is detected by setting a reset spring, and the suction force is adjusted so that the reset spring is repeatedly compressed and reset, driving the movable plate to collide with the limit plate, thereby shaking off the graphite powder on the filter plate and ensuring the ventilation volume of the filter plate.

[0029] 5. In the present invention, the height of the current graphite particle landing point is determined by the reset spring in conjunction with the traction spring, and the speed of the circumferential rotation of the flip plate is adjusted by the motor, so that the landing point is adjusted to within the standard landing point range, ensuring that the graphite particles can fully contact with the gas, so that the impurities in the graphite particles can be quickly separated, avoiding serious collisions when the graphite particles fall, resulting in an increase in graphite powder, preventing the graphite particles from being crushed and cracked, and ensuring the quality of the graphite particles.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] In order to solve the problems of uneven heating of graphite, difficulty in sufficient contact between graphite and gas resulting in difficulty in separating impurities, and floating graphite powder mixed with impurities, making subsequent separation of impurities more complicated and graphite recovery troublesome, Example 1 is proposed.

[0041] Example 1:

[0042] like Figures 1 to 8 As shown, the present invention provides a purification device, including a barrel assembly 1, a power assembly 2 is provided at one end of the barrel assembly 1, traction assemblies 3 are symmetrically provided at both ends of the interior of the barrel assembly 1, a flip plate 4 is provided on the traction assembly 3, and toggle assemblies 5 are evenly provided on both sides of the flip plate 4, a ventilation assembly 6 is provided on the central axis of the barrel assembly 1, a feed port 7 and an exhaust port 10 are provided at the top of the barrel assembly 1, a filter assembly 9 is provided in the exhaust port 10, and a discharge port 8 is provided at the bottom of the barrel assembly 1.

[0043] By setting up the traction component 3 and the flip plate 4, the traction component 3 drives the flip plate 4 to rotate in a circle, flipping the graphite particles at the bottom layer, so that the graphite particles at the top and bottom layers roll alternately, so that the graphite particles are evenly heated; at the same time, the gaps between the graphite particles are enlarged, which facilitates better mixing of the graphite particles and the gas; and the large pieces of graphite formed by mutual adhesion can be squeezed and crushed; by setting up the filtering component 9, the graphite powder generated by the flipping and collision of the graphite particles is filtered and separated from the gas, preventing the subsequent impurity separation steps from being cumbersome and affecting the graphite processing process.

[0044] During the heating process after the graphite particles are put into the inner cylinder 102, the graphite particles accumulate together, resulting in uneven heating of the graphite particles on the top layer and the graphite particles on the bottom layer. At the same time, the water vapor generated by the heated graphite particles on the bottom layer cannot be dissipated, resulting in the formation of agglomerates. In addition, the gaps between the graphite particles on the bottom layer are very small, resulting in insufficient contact between the gas and the graphite particles, thereby extending the purification time and reducing the purification efficiency.

[0045] In order to solve the above technical problems, in this embodiment, Figure 3As shown, by setting a traction component 3 to drive the flip plate 4 to rotate in a circle, the graphite particles at the bottom layer are flipped to the upper layer to ensure uniform heating and uniform contact with the gas. The traction component 3 includes a traction ring 301, and limit blocks 302 are fixedly provided at equal distances on the traction ring 301. A flip plate 4 is slidingly provided between the limit blocks 302, and a traction spring 303 is fixedly provided on one side of the flip plate 4; one end of the traction spring 303 is fixedly provided on the limit block 302, and the other end is fixedly provided on the flip plate 4. When the graphite particles fall between the flip plates 4 and continue to rotate to a higher position with the flip plate 4, the weight of the graphite particles will cause the flip plate 4 to slide downward along the traction ring 301, and the traction spring 303 will be compressed. When the graphite particles fall from between the flip plates 4, the elastic force of the traction spring 303 itself causes the flip plate 4 to quickly return to its position for the next flip. A turntable 304 is fixedly provided at one end of the limit block 302. An annular groove 306 is provided on the circumference of the turntable 304. A transmission cylinder 305 is provided on the central axis of the turntable 304. The power component 2 drives the turntable 304 to rotate through the transmission cylinder 305, thereby driving the flip plate 4 to rotate along the circumference.

[0046] When in use, the power assembly 2 drives the transmission cylinder 305 to rotate, and the transmission cylinder 305 drives the turntable 304 to rotate along the convex ring 106 on the inner cylinder 102, thereby driving the limit block 302 and the traction ring 301 to rotate, and then driving the flip plate 4 on the traction ring 301 to perform circular motion with the central axis of the turntable 304 as the center.

[0047] like Figure 3 As shown, when the turntable 304 rotates clockwise, the flip plate 4 rotates clockwise to the bottom layer of the graphite particles, and the graphite particles will fall between the flip plates 4. At the same time, the graphite particles generate resistance to the circular motion of the flip plate 4. Under the action of the resistance, the flip plate 4 will move in the counterclockwise direction, thereby driving the toggle components 5 to approach each other, squeezing and crushing the agglomerated graphite particles between the flip plates 4, and dispersing them.

[0048] As the flip plate 4 continues to rotate clockwise, the graphite particles on the bottom layer fall between the flip plates 4 and continue to rotate upward with the flip plate 4. When the flip plate 4 rotates to the dropping point in turn, the graphite particles above it are parabolic and fall to the bottom of the inner cylinder 102 in turn, thereby flipping the graphite particles on the bottom layer to the top layer, and flipping the graphite particles on the top layer to the bottom layer. As the flip plate 4 rotates, the graphite particles on the top and bottom layers continue to flip, thereby achieving uniform heating of the graphite particles in the longitudinal direction.

[0049] When the graphite particles are driven to the dropping point and dropped downward, the graphite particles disperse and fall, so that the gas input by the ventilation component 6 can fully contact and react with the graphite particles, so that the impurities in the graphite particles contact with the gas to form compounds, and gasify and overflow at high temperature, ensuring that the impurities in the graphite particles can fully contact and react with the gas to form compounds, accelerate the overflow of impurities, and accelerate the purification process.

[0050] By setting up a traction component 3 to drive the flip plate 4 to perform circular motion, the graphite particles on the bottom layer are continuously flipped to the top layer, so that the graphite particles are continuously flipped in the longitudinal direction to ensure uniform heating; at the same time, the graphite particles can fully contact with the gas during the flipping and falling process, thereby accelerating the reaction of impurities; while the flip plate 4 drives the graphite particles to rotate, the resistance generated by the graphite particles causes the flip plate 4 to drive the prying components 5 to approach each other, which can generate extrusion pressure on the agglomerated graphite particles and disperse them; thereby accelerating the purification efficiency of the graphite.

[0051] After the graphite particles are put into the inner cylinder 102, the graphite particles form a cone-shaped accumulation. With the subsequent rotation of the flip plate 4, the graphite particles will gradually disperse in the horizontal direction. However, the dispersion process is relatively slow, which is not conducive to the rapid dispersion and uniform heating of the graphite particles. Moreover, after the subsequent purification is completed, it is more difficult to discharge the material.

[0052] In order to solve the above technical problems, in this embodiment, Figure 4-Figure 5 As shown, by setting a toggle plate 501 on both sides of the flip plate 4, the graphite particles are toggled after being put into the inner cylinder 102, so that the graphite particles are quickly and evenly distributed in the horizontal direction, ensuring heating efficiency, and can also be quickly discharged during subsequent discharge. The toggle assembly 5 includes toggle plates 501 evenly set on both sides of the flip plate 4. The toggle plates 501 are rotatably set on the side of the flip plate 4. The toggle plates 501 are set with rectangular holes. The side of the rectangular hole away from the rotating gear 503 is provided with a blocking plate 509. The blocking plates 509 in the rectangular holes on both sides of the flip plate 4 are set in opposite directions, as shown in FIG. Figure 4As shown, the blocking plate 509 on the left side of the flip plate 4 is set on the side close to the traction ring 301, and the blocking plate 509 on the right side of the flip plate 4 is set on the side away from the traction ring 301. A rotating plate 502 is rotatably set in the rectangular hole, and a torsion spring is set at the rotation connection between the rotating plate 502 and the rectangular hole. A rotating gear 503 is set on the top of the toggle plate 501, and a transmission bar 505 is slidingly set on the top of the flip plate 4. There are two transmission bars 505 set in parallel, namely the left transmission bar 505 and the right transmission bar 505. A rack 504 is evenly set on the side of the transmission bar 505 facing the rotating gear 503, and the rack 504 is meshed with the rotating gear 503. When the movable bar 505 moves back and forth, the rack 504 can drive the rotating gear 503 to rotate repeatedly, thereby driving the toggle plate 501 to swing. A accommodating space is provided inside the flip plate 4. There are two accommodating spaces, which respectively control the reciprocating movement of the left transmission bar 505 and the right transmission bar 505. A cylinder 507 is fixedly provided in the accommodating space, and a moving column 506 is fixedly provided at the output end of the cylinder 507. A slide groove 508 is provided at one end of the accommodating space. The moving column 506 is engaged with the slide groove 508 and slides inside the slide groove 508. The top of the moving column 506 is fixedly connected to the transmission bar 505. The extension and contraction of the cylinder 507 can drive the transmission bar 505 to move back and forth.

[0053] During use, by controlling the extension and retraction of the output end of the cylinder 507, the movable column 506 is driven to slide along the slide groove 508, and the movable column 506 drives the transmission bar 505 to slide back and forth. The transmission bar 505 drives the rotating gear 503 to rotate through the rack 504, thereby driving the toggle plate 501 to realize a reciprocating swinging movement.

[0054] Before adding graphite particles, the output end of the right cylinder 507 is controlled to extend to the farthest distance, and the right toggle plate 501 is driven by the right transmission bar 505 to rotate toward the discharge port 8 until it is in contact with the flip plate 4.

[0055] Open the upper cover 103, put the graphite particles into the inner cylinder 102 from the feed port 7, close the upper cover 103, and control the left transmission bar 505 to move back and forth, driving the toggle plate 501 on the left side of the flip plate 4 to swing back and forth, thereby driving the graphite particles on the bottom layer to move toward the discharge port 8. Figure 4 As shown, when the toggle plate 501 on the left side rotates toward the discharge port 8, the blocking plate 509 restricts the rotating plate 502 from rotating, so that the toggle plate 501 temporarily maintains the state of a solid plate, pushing the graphite particles toward the discharge port 8. When the toggle plate 501 on the left side rotates toward the feed port 7, the rotating plate 502 rotates due to the resistance of the graphite particles, so that the rectangular hole of the toggle plate 501 opens and temporarily becomes a hollow plate state, so that the graphite particles can pass through the rectangular hole, preventing the graphite particles from being toggled back to their original position.

[0056] In the process of the left toggle plate 501 leveling the material toward the discharge port, the right toggle plate 501 is intermittently controlled to rotate toward the feed port 7, and the torsion spring is detected in real time to determine whether compression occurs, thereby determining whether the left rotating plate 502 rotates, and then detecting whether the graphite particles have been evenly distributed. The specific process is: the output end of the right cylinder 507 is controlled to retract a distance, which is set to the detection distance, and the right toggle plate 501 is driven by the right transmission bar 505 to rotate a certain angle away from the flip plate 4; at this time, if there are graphite particles at the current position, the graphite particles will generate resistance to the right rotating plate 502, causing the right rotating plate 502 to rotate and the right torsion spring to be compressed, indicating that there are graphite particles at the current position; if there are no graphite particles at the current position, when the right toggle plate 501 rotates, no graphite particles generate resistance to the right rotating plate 502, and no compression of the torsion spring occurs. The output end of the right cylinder 507 is controlled to repeatedly extend and retract the detection distance until the last right-side shifting plate 501 on the end of the flip plate 4 near the discharge port 8 rotates, causing the rotating plate 502 in its rectangular hole to rotate and the torsion spring to compress, indicating that the current graphite particles have been shifted horizontally to cover the bottom of the inner cylinder 102. At this time, the shifting of the left shifting plate 501 is stopped, and the detection of the right shifting plate 501 is stopped. The expansion and contraction of the two cylinders 507 are controlled to adjust to the initial expansion and contraction. At this time, the shifting plates 501 on the left and right sides are parallel to each other. The heating plate 105 is then turned on to start heating, and the power assembly 2 is started to drive the flip plate 4 to perform subsequent actions such as flipping.

[0057] During the discharge phase, the flip plate 4 continues to flip the graphite particles. The left-side shifting plate 501 is controlled to swing back and forth, driving the graphite particles toward the discharge port 8. The output end of the right-side cylinder 507 is repeatedly extended and retracted, with the retraction frequency synchronized with the rotational speed. Specifically, when the flip plate 4 rotates to the bottom of the inner cylinder 102, the output end of the right-side cylinder 507 is controlled to retract to detect the presence of graphite particles. When the flip plate 4 rotates above the drop point, the output end of the right-side cylinder 507 is controlled to extend to complete the detection. This detection process repeats as the flip plate 4 rotates until the torsion spring in the rectangular hole of the last right-side shifting plate 501 on the flip plate 4 near the discharge port 8 is not compressed, indicating that the rotating plate 502 is not rotating and the graphite particles have been completely removed from the discharge port. The flip plate 4 stops rotating, and the cylinder 507 stops extending and retracting, completing the purification process.

[0058] By setting up the toggle plate 501, the conical accumulation formed after the graphite particles are fed is dispersed and evenly distributed, thereby accelerating the uniform dispersion of the graphite particles in the lateral direction, and facilitating the subsequent uniform heating of the graphite particles. In addition, when the graphite particles are discharged, the toggle plate 501 assists in the discharge, and at the same time, by detecting whether the torsion spring is compressed, it is determined whether the current rotating plate 502 is rotating, thereby detecting whether there are graphite particles at the current position of the toggle plate 501, and then determining whether the graphite is evenly dispersed or whether the graphite has been discharged.

[0059] During the tumbling of the graphite particles, the collision between the graphite particles will produce graphite powder. As the ventilation component 6 continues to introduce gas, the airflow brought by the gas causes the graphite powder to fly inside the inner tube 102 and mix with the vaporized impurities. If filtration and separation are not performed, the extracted vaporized impurities will be mixed with graphite powder, which will make the subsequent impurity separation process cumbersome.

[0060] In order to solve the above technical problems, Figure 6 As shown, in this embodiment, the graphite powder is filtered by setting a filter component 9, and the filter component 9 includes a filter plate 901, and a movable plate 902 is set at the four corners of the filter plate 901. The movable plate 902 is slidably set on the inner wall of the exhaust port 10, and the filter plate 901 can drive the movable plate 902 to slide along the inner wall of the exhaust port 10. A return spring 903 is fixedly set on the top of the movable plate 902. Under the support of the elastic force of the return spring 903, the movable plate 902 and the limit plate 905 can fit tightly; a fixed plate 904 is fixedly set on the inner side of the exhaust port 10, and the fixed plate 904 is set corresponding to the movable plate 902. One end of the return spring 903 is fixedly set on the movable plate 902, and the other end is fixedly set on the fixed plate 904. A limit plate 905 is fixedly set at the bottom of the exhaust port 10, and the limit plate 905 is set corresponding to the movable plate 902.

[0061] When in use, the exhaust port 10 is connected to an external suction machine. During the heating and purification process of the graphite particles, the ventilation component 6 continuously introduces gas, and the graphite particles continuously flip and come into contact with the gas, so that the internal impurities react with the gas to form compounds. The compounds are vaporized at high temperature and are extracted from the exhaust port 10 by the external suction machine. The vaporized impurities are extracted with the suction machine, and the graphite powder is retained inside the inner cylinder 102 by the filter plate 901.

[0062] When too much graphite powder adheres to the filter plate 901, it will affect the gas flow rate. When the gas extraction speed slows down or even cannot be extracted, the ventilation component 6 continues to introduce gas, which will cause the internal pressure of the inner tube 102 to increase. The inner wall of the inner tube 102 is compressed, resulting in more serious consequences. Therefore, it is necessary to always maintain the gas flow rate of the filter plate 901.

[0063] In the initial stage, the movable plate 902 and the limit plate 905 are in a fit and maintained state, the compression amount of the return spring 903 is the initial compression amount, and the suction force exerted on the filter plate 901 is equal to the elastic force exerted on the return spring 903 or the suction force is less than the elastic force of the return spring 903.

[0064] When the compression of return spring 903 increases, it indicates that there is an excessive amount of graphite powder adhering to filter plate 901, resulting in a decrease in the amount of gas passing through filter plate 901. Consequently, at the same suction force as in the initial stage, the suction force on filter plate 901 becomes greater than the spring force, causing movable plate 902 to slide upward along the inner wall of exhaust port 10. This causes return spring 903 to be compressed a second time, increasing the amount of compression. At this point, the external suction mechanism is controlled to regularly increase and decrease the suction force, causing the suction force on filter plate 901 to repeatedly increase and decrease, from greater than the spring force to less than the spring force. Return spring 903 is compressed three times before returning to its original position. During this reset, movable plate 902 collides with stop plate 905, generating a vibration force that shakes off the graphite powder adhering to filter plate 901, thereby clearing the graphite powder from filter plate 901 and ensuring a high gas flow rate through filter plate 901.

[0065] By setting the filter plate 901, when the gasified impurities inside the inner cylinder 102 are extracted at the exhaust port 10, the graphite powder floating in the gasified impurities is filtered and separated, so as to prevent the subsequent impurity separation steps from being cumbersome. By setting the reset spring 903, the ventilation volume of the filter plate 901 is detected. By adjusting the suction force, the reset spring 903 is repeatedly compressed and reset, driving the movable plate 902 to collide with the limit plate 905, thereby shaking off the graphite powder on the filter plate 901 and ensuring the ventilation volume of the filter plate 901.

[0066] like Figure 8 As shown, the ventilation component 6 includes a straight-through pipe 603 uniformly arranged inside the cylinder component 1, and diverter pipes 602 are symmetrically arranged at both ends of the straight-through pipe 603. An input pipe 601 and an auxiliary shaft 605 are fixedly arranged on the side of the diverter pipe 602 away from the straight-through pipe 603. The parts of the input pipe 601 and the auxiliary shaft 605 extending out of the support frame 107 are fixed with external fixing components to ensure the overall stability of the ventilation component 6. The input pipe 601, the diverter pipe 602 and the straight-through pipe 603 are internally connected, and the input pipe 601 and the auxiliary shaft 605 extend out of the cylinder component 1 at one end away from the diverter pipe 602. The straight-through pipe 603 is uniformly provided with air outlets 604, and a one-way valve is provided in the air outlet 604 to ensure one-way output of gas. The transmission cylinder 305 is rotatably arranged on the outside of the input pipe 601 and the auxiliary shaft 605.

[0067] In this embodiment, one end of the input pipe 601 extending out of the inner cylinder 102 is fixedly connected to an external air supply pump. The air supply pump inputs the gas from the input pipe 601 into the diversion pipe 602 and the straight pipe 603, and then outputs it from the outlet 604, so as to fully contact the graphite particles.

[0068] like Figure 7-Figure 8 As shown, the barrel assembly 1 includes an outer barrel 101 and an inner barrel 102. The inner side of the outer barrel 101 and the outer side of the inner barrel 102 are separated. A heating plate 105 is fixedly provided on the outer side of the inner barrel 102. The heating plate 105 is separated from the inner side of the outer barrel 101. A cooling component can be set in this space to cool the inner barrel 102 after subsequent purification. Fixed ring plates 104 are provided at both ends of the outer barrel 101. The fixed ring plates 104 are arranged inside the outer barrel 101. The inner barrel 102 and the heating plate 105 are fixed on the fixed ring plates 104. The feed port 7 and the discharge port 8 are respectively arranged at the top and bottom of the inner barrel 102. The feed port 7 and the discharge port 8 are respectively provided with an upper cover 103 and a lower cover 104. 8; Both ends of the inner cylinder 102 are provided with convex rings 106, which are engaged with the annular groove 306. When the turntable 304 rotates, the annular groove 306 and the convex ring 106 rotate relative to each other, and the outer side of the transmission cylinder 305 is provided with a support frame 107; the power assembly 2 includes a driven wheel 204 fixedly arranged on the outer side of the transmission cylinder 305, and a transmission belt 203 is wound around the circumference of the driven wheel 204. The end of the transmission belt 203 away from the driven wheel 204 passes around the driving wheel 202, and a motor 201 is fixedly provided on one side of the driving wheel 202. The motor 201 is fixedly provided on the support frame 107 through a fixing frame 206, and a protective shell 205 is provided on the outer side of the driving wheel 202 and the driven wheel 204.

[0069] In this embodiment, the motor 201 is controlled to start, driving the driving wheel 202 to rotate, and the driving wheel 202 drives the driven wheel 204 to rotate through the transmission belt 203, thereby driving the transmission cylinder 305 and the turntable 304 to rotate, and further driving the flip plate 4 to rotate in a circle.

[0070] The working principle of the present invention is as follows: First, the material is fed and mixed, and heating is started. Before the graphite particles are added, the output end of the right cylinder 507 is controlled to extend to the maximum distance, and the right transmission bar 505 is used to drive the right toggle plate 501 to rotate toward the discharge port 8 until it is in contact with the flip plate 4. The upper cover 103 is opened, and after the graphite particles are added from the feed port 7 into the inner cylinder 102, the upper cover 103 is closed, and the left transmission bar 505 is controlled to move back and forth, driving the toggle plate 501 located on the left side of the flip plate 4 to swing back and forth, thereby driving the graphite particles on the bottom layer to move toward the discharge port 8. While the left toggle plate 501 is mixing the material toward the discharge port, the right toggle plate 501 is intermittently controlled to rotate toward the feed port 7, and the torsion spring is detected in real time to determine whether it is compressed, thereby determining whether the left rotating plate 502 is rotating, and further detecting whether the graphite particles have been mixed. The specific process is as follows: the output end of the right cylinder 507 is controlled to retract a certain distance, which is set as the detection distance. The right transmission bar 505 drives the right toggle plate 501 to rotate a certain angle away from the flip plate 4. At this time, if the right torsion spring is compressed, it means that there are graphite particles at the current position. The graphite particles produce resistance to the right rotating plate 502, causing the right rotating plate 502 to rotate, thereby compressing the torsion spring. If the right torsion spring is not compressed, it means that there are no graphite particles at the current position. When the right toggle plate 501 rotates, there are no graphite particles to resist the right rotating plate 502, and the torsion spring is not compressed. The output end of the right cylinder 507 is controlled to repeatedly extend and retract the detection distance until the last right toggle plate 501 on the flip plate 4 near the discharge port 8 rotates. The torsion spring is compressed, indicating that the rotating plate 502 in its rectangular hole has rotated. The current graphite particles have been moved horizontally to cover the bottom of the inner cylinder 102. At this time, stop the material shifting of the left toggle plate 501, stop the detection of the right toggle plate 501, control the expansion and contraction of the two cylinders 507 to adjust to the initial expansion and contraction, at this time, the left and right toggle plates 501 are parallel to each other, and then turn on the heating plate 105 to start heating.

[0071] Secondly, the graphite is turned over and gas is introduced. When the graphite is heated to the required production temperature, the motor 201 is started to drive the driving wheel 202 to rotate. The driving wheel 202 drives the driven wheel 204 to rotate through the transmission belt 203, thereby driving the transmission cylinder 305 to rotate. The transmission cylinder 305 drives the turntable 304 to rotate along the convex ring 106 on the inner cylinder 102, thereby driving the limit block 302 and the traction ring 301 to rotate, and then drives the flip plate 4 on the traction ring 301 to do a circular motion with the central axis of the turntable 304 as the center. Figure 3For example, when the turntable 304 rotates clockwise, the flip plate 4 rotates clockwise to the bottom layer of graphite particles, and the graphite particles will fall between the flip plates 4. At the same time, the graphite particles generate resistance to the circular motion of the flip plate 4. Under the action of the resistance, the flip plate 4 will move in the counterclockwise direction, thereby driving the toggle components 5 to approach each other, squeezing and crushing the agglomerated graphite particles between the flip plates 4, and dispersing them. As the flip plate 4 continues to rotate clockwise, the graphite particles on the bottom layer fall between the flip plates 4 and continue to rotate upward as the flip plate 4 rotates. When the flip plate 4 rotates to the drop point in turn, the graphite particles above it form a parabola and fall to the bottom of the inner cylinder 102 in turn, thereby flipping the graphite particles on the bottom layer to the top layer and flipping the graphite particles on the top layer to the bottom layer. As the flip plate 4 rotates, the graphite particles on the top and bottom layers continue to flip, achieving uniform heating of the graphite particles in the longitudinal direction. The external air supply pump is started synchronously with the motor 201. The air supply pump inputs gas from the input pipe 601 into the diversion pipe 602 and the straight pipe 603, and then outputs it from the outlet 604. When the graphite particles are driven to the landing point and thrown downward, the graphite particles disperse and fall, so that the gas input from the outlet 604 fully contacts and reacts with the graphite particles, so that the impurities in the graphite particles contact with the gas to form compounds, and then gasify and overflow at high temperature.

[0072] Next, the gas is filtered and the filter plate is cleaned. An external suction machine continuously extracts the gas from inner cylinder 102 through exhaust port 10. The vaporized impurities are extracted by the suction force, while the graphite powder is retained within inner cylinder 102 by filter plate 901. Initially, movable plate 902 and retaining plate 905 remain in contact, and return spring 903 is compressed to its initial value. The suction force acting on filter plate 901 is equal to or less than the elastic force of return spring 903. When the compression of return spring 903 increases, this indicates that excessive graphite powder is attached to filter plate 901, resulting in a decrease in gas flow through filter plate 901. Consequently, the suction force acting on filter plate 901 becomes greater than the elastic force, driving movable plate 902 upward along the inner wall of exhaust port 10. This causes return spring 903 to undergo a secondary compression, increasing the compression. At this time, the external suction machine is controlled to regularly increase and decrease the suction force repeatedly, so that the suction force on the filter plate 901 increases and decreases repeatedly, and the suction force changes from being greater than the elastic force to being less than the elastic force. The reset spring 903 is repeatedly compressed three times and then reset. During the reset, the moving plate 902 collides with the limit plate 905, thereby generating a vibration force to shake off the graphite powder on the filter plate 901, thereby completing the cleaning of the graphite powder attached to the filter plate 901 and ensuring the gas flow rate of the filter plate 901.

[0073] Finally, the purification is completed and the graphite is discharged. The inner cylinder 102 is first cooled by the cooling component. When the temperature inside the inner cylinder 102 drops to a certain temperature, the material is discharged. The flip plate 4 continuously flips the graphite particles, and the toggle plate 501 on the left is controlled to swing back and forth, thereby driving the entire graphite particles to move toward the discharge port 8 for discharge. The output end of the cylinder 507 on the right is controlled to repeatedly extend and retract the detection distance. At this time, the retraction frequency is synchronized with the rotation speed. Specifically, when the flip plate 4 rotates as a whole to the bottom of the inner cylinder 102, the output end of the right cylinder 507 is controlled to retract to a detection distance to detect the presence of graphite particles. When the flip plate 4 rotates as a whole and exceeds the drop point, the output end of the right cylinder 507 is controlled to extend to a detection distance, completing one detection step. As the flip plate 4 rotates, the detection steps are repeated until the torsion spring in the rectangular hole of the last right-hand paddle 501 on the end of the flip plate 4 near the discharge port 8 is not compressed when the paddle 501 rotates, indicating that the rotating plate 502 has not rotated and the current graphite particles have been completely pushed out of the discharge port. The rotation of the flip plate 4 and the extension and retraction of the cylinder 507 are stopped, and the purification process ends.

[0074] Based on the technical solution of the above-mentioned embodiment 1, according to actual production needs, the shape, particle size and density of the produced graphite particles are different. The quality of the graphite particles with different shapes, particle sizes and densities is inconsistent, resulting in differences in the positions of the landing points during their circular motion. If the landing point is too high, the graphite particles will collide more severely when falling, and the amount of graphite powder produced will increase, and may even cause the graphite particles to shatter and crack. If the landing point is too low, the graphite particles will not be able to fully contact the gas, affecting the reaction rate of the impurities and thus affecting the purification efficiency. Therefore, the following embodiment 2 is proposed to solve the above-mentioned technical problems.

[0075] Example 2:

[0076] By real-time detecting the duration of the change in ventilation volume of the filter plate 901 and the deformation time of the traction spring 303, the height of the current graphite particle landing point can be judged, and the speed of the circular motion of the flip plate 4 can be adjusted by the power component 2 or the height of the landing point can be adjusted by cooperating with the toggle component 5 to ensure that the height of the landing point is maintained within a certain range.

[0077] Different rotational speeds are used for graphite particles of varying quality to ensure their drop point remains within a standard drop point range. At different rotational speeds, the time it takes to reach the drop point from the bottom of the inner cylinder 102 is also within a standard range. The rotational speed of the flip plate 4 is adaptively adjusted for each purified graphite particle, and the drop time is adjusted accordingly. Therefore, if the quality of the purified particles differs from that of the previously purified graphite particles, the rotational speed needs to be adjusted.

[0078] When the interval between the two deformations of the reset spring 903 is significantly shortened, and at the same time, the reset time of the traction spring 303 is significantly lengthened, it can be judged that the current rotation speed of the flip plate 4 is too fast, the graphite particle landing point is too high, and the falling time is too long. The high falling point causes the graphite particles to fall to a higher height, thereby causing the collision force between the graphite particles and the graphite particles on the bottom layer of the inner cylinder 102 to increase when they fall, resulting in an increase in the graphite powder generated by the collision. The increase in graphite powder accelerates the clogging speed of the filter plate 901, thereby shortening the time between the two compression changes of the reset spring 903; when the graphite particles fall to a higher height, the graphite particles stay on the flip plate 4 for a longer time, thereby lengthening the reset time of the traction spring 303. The reset time of the traction spring 303 represents the falling time. At this time, by slowing down the rotation speed of the motor 201, the circumferential rotation speed of the flip plate 4 gradually slows down until the interval between the two deformations of the reset spring 903 tends to be normal. At the same time, the reset time of the traction spring 303 is shortened, that is, the dropping time returns to the standard time range, which means that the dropping point of the graphite particles is within the standard dropping point range at this time, and the rotation speed of the flip plate 4 matches the current graphite particles.

[0079] When the interval between the two deformations of the reset spring 903 becomes significantly longer, and at the same time, the reset time of the traction spring 303 becomes significantly shorter, it can be judged that the current rotation speed of the flip plate 4 is slow, and the graphite particles begin to leak before reaching the throwing point range, and the throwing time is short. The graphite particles begin to leak to the bottom of the inner cylinder 102 before reaching the throwing point range, resulting in the graphite particles being unable to be dispersed and thrown, thereby causing the collision force of the graphite particles with the bottom graphite particles of the inner cylinder 102 to become smaller when falling, and the collision produces very little graphite powder or no graphite powder. The less graphite powder slows down the clogging speed of the filter plate 901, thereby causing the time length of the two compression changes of the reset spring 903 to become longer; when the falling height of the graphite particles becomes lower, the time the graphite particles exist on the flip plate 4 becomes shorter, thereby shortening the reset time of the traction spring 303, and the reset time of the traction spring 303 represents the throwing time. At this time, by accelerating the rotation speed of the motor 201, the circumferential rotation speed of the flip plate 4 gradually becomes faster until the interval between the two deformations of the reset spring 903 tends to be normal. At the same time, the reset time of the traction spring 303 becomes longer, that is, the dropping time returns to the standard time range, which means that the dropping point of the graphite particles is now within the standard dropping point range, and the rotation speed of the flip plate 4 matches the current graphite particles.

[0080] When the traction spring 303 maintains the compression amount without resetting, it can be determined that the current rotation speed of the flip plate 4 far exceeds the rotation speed corresponding to the current graphite particles, causing the graphite particles to become a turnover state, and cannot be thrown off as the flip plate 4 rotates synchronously. At this time, the output ends of the two cylinders 507 are controlled to repeatedly expand and contract, driving the toggle plates 501 on the left and right sides to swing back and forth, to toggle the graphite particles, breaking the turnover state of the graphite particles, causing the graphite particles to collide with each other and begin to fall. At the same time, the rotation speed of the motor 201 is quickly reduced, so that the circumferential rotation speed of the flip plate 4 gradually slows down, allowing the graphite particles to be thrown off, and then the throwing point is adjusted according to the above two methods.

[0081] The height of the current graphite particle landing point is determined by the reset spring 903 in cooperation with the traction spring 303, and the speed of the circumferential rotation of the flip plate 4 is adjusted by the motor 201, so that the landing point is adjusted to the standard landing point range, ensuring that the graphite particles can fully contact with the gas, so that the impurities in the graphite particles can be quickly separated, avoiding serious collisions when the graphite particles fall, resulting in an increase in graphite powder, preventing the graphite particles from being crushed and cracked, and ensuring the quality of the graphite particles.

[0082] Example 3:

[0083] The present invention also discloses a purification method of the purification device, comprising the following steps:

[0084] Step 1: Feed and heat. Open the upper cover 103, put graphite particles into the inner cylinder 102 from the feed port 7, then close the upper cover 103, start the heating plate 105 to heat the inner cylinder 102 until it reaches the production temperature.

[0085] Step 2: Turn the graphite. Start the motor 201 and drive the turntable 304 to rotate through the transmission cylinder 305, thereby driving the flip plate 4 to flip the graphite particles, flipping the graphite particles on the bottom layer to the top layer, and flipping the graphite particles on the top layer to the bottom layer, and rolling the graphite particles in a cycle to ensure uniform heating.

[0086] Step 3: Gas mixing: Start the ventilation assembly 6 to introduce gas into the inner cylinder 102 to mix with the tumbling graphite particles, so that the impurities in the graphite particles are gasified and separated from the graphite.

[0087] Step 4: Filter the graphite. The gas carrying the gasified impurities is discharged from the exhaust port 10 , and the powdered graphite is intercepted by the filter assembly 9 in the inner cylinder 102 .

[0088] Step 5: Discharge the graphite. After the heating and purification is completed, stop the gas supply from the ventilation component 6, extract the gas inside the inner cylinder 102 through the exhaust port 10, and discharge the graphite particles from the discharge port 8 after cooling.
