Description

Technical Field

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

[0002] Graphite is widely used in battery negative electrode materials, nuclear graphite in the nuclear industry, high temperature resistant graphite and stealth materials for military use, anti-corrosion materials, conductive materials, metallurgical industry, petrochemical industry, etc. It is a very important industrial material. At present, the main equipment used for the production of graphitized powder at home and abroad include Acheson graphitization furnace, tandem graphitization furnace and electrode direct heating graphitization furnace.

[0003] A Chinese patent with publication number CN116835582A discloses a graphitization purification system, including a high-temperature graphitization continuous heating bin and a finished product conveying mechanism installed at the bottom of the high-temperature graphitization continuous heating bin, a dispersion plate is rotatably connected between the to-be-processed delivery mechanism and the high-temperature graphitization continuous heating bin, an annular distributor is installed on the to-be-processed delivery mechanism, and a plurality of quantitative feeding holes are opened on the dispersion plate.

[0004] It is found in the above technical scheme that although the graphite powder is fed in batches through an annular distributor to avoid extrusion and blockage of the graphite powder in the bottom feeding hole, the graphite powder will sinter during the high-temperature purification process, and the size of the sintered graphite powder will increase, which will make the sintered graphite powder fall into the bottom feeding hole and still be prone to extrusion and blockage. In addition, when the graphite powder is freely fed, if the graphite powder falls to the heating zone and is unevenly distributed, the gaps in the graphite powder after high-temperature sintering will be smaller, making the porosity of the graphite powder smaller, thereby affecting the subsequent absorption rate and conductivity of the graphite powder and other related issues.

[0025] 2. The present invention cooperates with components such as a limit ring and an electric control push rod. When the electric control push rod controls the surface of the second disc to contact and collide with the bottom of the limit ring, vibration will be generated, which will cause the graphite powder on the second disc to bounce up, thereby achieving the change of the position where the graphite powder is accumulated. At the same time, when the electric control push rod controls the second disc to continue to squeeze the limit ring, the second disc will be deformed, so that the second disc passes through the limit ring and contacts and collides with the bottom of the dispersion plate at the upper end of the processing tube. At the same time, the second disc continues to be controlled to squeeze the bottom of the dispersion plate, so that the graphite powder will split when it is hit and squeezed, thereby achieving the effect of squeezing and crushing the graphite powder.

[0037] The present invention provides Figures 1 to 9 A graphitization purification device shown includes a feed assembly 1, a processing assembly 2 and a discharge assembly 3. The feed assembly 1 is provided at the upper end of the processing assembly 2, and the discharge assembly 3 is provided at one end of the processing assembly 2 away from the feed assembly 1.

[0038] The feed assembly 1 includes a feed pipe 101, a protective plate 102 is provided at the bottom end of the feed pipe 101, the bottom surface of the protective plate 102 is arranged at the top end of the insulation tube 201, and one end of the feed pipe 101 close to the insulation tube 201 is connected to the inside of the furnace body 204 through the protective plate 102.

[0039] A fixing frame 103 is provided on one side of the inner wall of the protection plate 102, and a driving motor 104 is provided on the inner side of the fixing frame 103, a transmission rod 105 is provided on the output end of the driving motor 104, and a scraper 107 is provided on the end of the transmission rod 105 away from the driving motor 104, a filter plate 108 is provided on the bottom surface of the scraper 107, and a silo 106 is provided on the lower surface of the filter plate 108, and the outer side of the silo 106 is arranged inside the furnace body 204, and the bottom end of the silo 106 is connected to the processing pipe 207. The top ends of the two plates are interconnected. When in use, the graphite powder enters the upper end of the furnace body 204 through the feed pipe 101, and then cooperates with the transmission of the drive motor 104 to control the bottom of the scraper 107 to contact with the surface of the filter plate 108 and rotate on its surface, so that the graphite powder particles will move in the direction of rotation of the scraper 107. When the graphite powder moves to the filter holes on the filter plate 108, it will directly enter the processing tube 207 inside the furnace body 204 for heating processing.

[0040] The discharge component 3 includes a discharge pipe 301, one end of which is provided with a micro motor 302, and the output end of the micro motor 302 is provided with a conveying rod 303, the surface of the conveying rod 303 is provided with an auger blade, and the outer edge of the auger blade is tightly fitted with the inner wall of the discharge pipe 301. When in use, after the graphite powder purification work is completed, the graphite powder will enter the discharge pipe 209 through the filter bin 208, and then open the first one-way valve to allow the graphite powder to enter the discharge component 3, and control the conveying rod 303 to rotate by turning on the micro motor 302. Since the surface of the conveying rod 303 is provided with an auger blade, the graphite powder can be discharged to the outside during the rotation of the auger blade.

[0041] The processing assembly 2 includes a furnace body 204, a fixed plate 216 is arranged inside the furnace body 204, a heating tube 206 is arranged on the surface of the fixed plate 216, a heat collecting sleeve is arranged on one side of the heating tube 206, and the number of the heating tubes 206 is five, and each heating tube 206 is arranged in a circular array on the surface of the fixed plate 216. When in use, the surface of the processing tube 207 is heated by turning on a plurality of heating tubes 206, so that the processing tube 207 can be quickly at a high temperature, and because the plurality of heating tubes 206 are arranged in a circular array on the outer surface of the processing tube 207, it is convenient for the stone The toner is heated evenly. At the same time, during the heat release process of the heating tube 206, the heat released by the heating tube 206 can be concentrated on the surface of the processing tube 207 through the heat collection sleeve, which is not easy to diffuse outward, which not only improves the heating efficiency of the graphite, but also prevents the rapid loss of heat. The surface of the furnace body 204 is provided with a heat insulation tube 201, and the bottom of the inner wall of the furnace body 204 is provided with a filter chamber 208. The interior of the filter chamber 208 is provided with an electric control push rod 210. The surface of the electric control push rod 210 close to the first disk 212 is provided with a driving block 211. The driving block 21 1 is located at the center of the processing tube 207. A density detector is arranged on the outside of the processing tube 207. The outside of the density detector is covered with a heat-insulating film. When the electric push rod 210 contracts, the driving block 211 is first controlled to move downward with the electric push rod 210, so that the bottom of the driving block 211 contacts the surface of the filter chamber 208 and applies pressure to the surface of the filter chamber 208, so that the filter chamber 208 is deformed. At the moment when the filter chamber 208 is deformed, part of the internal gas is discharged outward through the surface mesh, thereby squeezing the blocked stone. The toner is blown, and when the electric control push rod 210 controls the driving block 211 to move upward and controls one side of the driving block 211 not to contact the surface of the filter bin 208, the filter bin 208 will quickly reset, thereby bouncing off the graphite powder on its surface, thereby achieving an anti-clogging effect. A first disc 212 is provided at the output end of the electric control push rod 210, a compression tube is provided on one side of the first disc 212, and a second disc 213 is provided at one end of the compression tube away from the first disc 212, and an electromagnet 215 is provided on the side of the first disc 212 close to the second disc 213.

[0042] A processing tube 207 is provided inside the furnace body 204, and a discharge tube 209 is provided at the bottom of the furnace body 204. The end of the discharge tube 209 away from the furnace body 204 is arranged on the surface of the discharge tube 301, and the bottom end of the discharge tube 209 is connected with the discharge tube 301. By setting the discharge tube 301, the purified graphite powder can smoothly pass through the filter bin 208 into the inside of the discharge tube 301, and then the micro motor 302 drives the conveying rod 303 to discharge the graphite powder in the discharge tube 301 to the outside, completing the conveying function of the graphite powder. A dispersion plate 205 is provided at the top, and a limiting ring 214 is provided on one side of the inner wall of the processing tube 207. The diameter of the limiting ring 214 is smaller than the second disc 213. The second disc 213 and the first disc 212 are both slidably arranged inside the processing tube 207. An exhaust pipe 202 is provided on the surface of the processing tube 207. The exhaust pipe 202 passes through the furnace body 204 and the insulation tube 201 in sequence. The end of the exhaust pipe 202 away from the insulation tube 201 is connected to the processing tube 207. There are multiple exhaust pipes 202, and the symmetrical part of each exhaust pipe 202 is on the surface of the processing tube 207.

[0043] An air inlet pipe 203 is provided on the surface of the processing tube 207 close to the exhaust pipe 202, and the air inlet pipe 203 passes through the furnace body 204 and the insulation tube 201 in sequence. The end of the air inlet pipe 203 away from the insulation tube 201 is connected to the processing tube 207. When in use, when the graphite powder is heated to 2000°C, the impurities inside it will be gasified, and the gasified impurities will be discharged to the outside through multiple exhaust pipes 202 in the furnace body 204, thereby improving the purity of the graphite powder, and controlling the first disc 212 and the second disc 213 to contact and collide with one side of the limit ring 214 through the electric control push rod 210, thereby vibrating the graphite powder located on the second disc 213, thereby changing the position of the graphite powder at this time, so that it is evenly distributed inside the processing tube 207, to prevent the gap on the surface of the graphite powder from being too small due to uneven distribution after the graphite powder is sintered.

[0044] A graphitization purification system comprises a purification device and a purification control component, wherein the purification control component comprises a controller, a heater and a vacuum system, wherein the controller is arranged on the surface of a furnace body 204, the heater is arranged on the lower surface of the inner wall of the furnace body 204, and the vacuum system is arranged at the bottom end of a processing tube 207. With the cooperation of the controller and the heater, the heating tube 206 can be started to release heat to the surface of the processing tube 207, so that the graphite powder in the heating tube 206 is heated evenly. At the same time, before heating, the air inside the furnace body 204 is extracted through the vacuum system to prevent the graphite powder from contacting with oxygen during high temperature and causing oxidation, and then the protective gas is injected into the furnace body 204 through the vacuum system to protect the surface of the graphite powder and prevent the graphite powder from excessively expanding after being heated, thereby causing changes in its internal structure.

[0045] In summary, during use, the graphite powder is transported to the protective plate 102 through the feed pipe 101 in the feed assembly 1. When the graphite powder enters the protective plate 102, it will first fall into the surface of the filter plate 108. At this time, the drive motor 104 is turned on to control the rotating shaft to make a circular motion. At the same time, the rotating shaft will control the scraper 107 to make a circular motion. When the scraper 107 is moving, the bottom of the scraper 107 is in contact with the surface of the filter plate 108, so that the graphite powder on the filter plate 108 can be pushed during the rotation of the scraper 107. At the same time, when the particle size of the graphite powder is large, it will be stuck in the bottom of the scraper 107 during the rotation of the scraper 107, so that the scraper 107 squeezes the surface of the graphite powder to avoid the graphite powder being stuck in the sieve holes on the surface of the filter plate 108, resulting in graphite powder extrusion and blockage.

[0046] When the graphite powder is driven by the scraper 107, it will move on the filter plate 108 and enter the interior of the processing tube 207 through the sieve holes on the filter plate 108. Then, the heating tube 206 in the processing assembly 2 is controlled to heat the surface of the processing tube 207, so that the graphite powder in the processing tube 207 is rapidly heated. When the graphite powder is heated to above 2000°C, the impurities inside it will be gasified, and the gasified gas will be discharged to the outside through the exhaust pipe 202 on one side of the furnace body 204. When the graphite powder is purified, the electric control push rod 210 is controlled to push downward, so that part of the graphite powder on the second disc 213 will directly fall and enter the filter bin 208, and at this time, the electromagnet 215 on the inner side of the first disc 212 is controlled to press the second disc 213. 213, and the first disc 212 and the second disc 213 are moved closer to each other by the magnetic attraction, and the compression tube is deformed, and the gas inside the compression tube is discharged outward, thereby spraying the graphite powder on the second disc 213 outward, so that the graphite powder can completely fall into the filter bin 208. At the same time, after the first disc 212 and the second disc 213 overlap with each other, a small vibration is generated, and the graphite powder on the second disc 213 can be shaken off to the surface of the filter bin 208, and then enter the discharge pipe 209 through the filter bin 208. At this time, the one-way valve in the discharge pipe 209 is opened, so that the graphite powder in the discharge pipe can enter the discharge pipe 301, and the micro motor 302 controls the conveying rod 303 to convey the graphite powder to the outside.

[0047] It is worth noting that the initial position of the second disc 213 is the bottom position of the processing tube 207. When the second disc 213 is at the initial position, the bottom end of the processing tube 207 is not interconnected with the bottom end of the furnace body 204. When the graphite powder purification is completed, the electric control push rod 210 is controlled to drive the second disc 213 to leave the processing tube 207. At this time, the bottom end of the processing tube 207 is interconnected with the bottom of the furnace body 204, and the graphite powder inside can directly fall into the surface of the filter bin 208.

[0048] It is worth noting that: by setting a density sensor on the outside of the processing tube 207, the distribution state of the graphite powder inside the processing tube 207 can be reflected by the density value. At the same time, when the graphite powder is heated and sintered, the size of the surface gap of the sintered graphite powder is also required to be detected by a density detector and reflected by the density value.

[0049] When the density detector detects that the density of the graphite powder inside the processing tube 207 is higher than the preset value, it means that the graphite powder falling into the processing tube 207 has a small particle size and is evenly distributed, so that the density of the graphite powder in the processing tube 207 is high. At this time, when the graphite powder is sintered, the gap on the surface of the graphite powder is too small, so the following adjustments are made:

[0050] First, the electric control push rod 210 is controlled to push upward, and the second disc 213 is controlled to slide upward on the inner wall of the processing tube 207. Since the inner wall of the processing tube 207 is provided with a plurality of protrusions, the second disc 213 will vibrate when sliding in the processing tube 207. At this time, the graphite powder on the surface of the second disc 213 will be in a jumping state. However, when the surface of the second disc 213 contacts the bottom of the limiting ring 214 and hits the bottom of the limiting ring 214, an impact force is generated, so that the graphite powder is bounced up, so that the accumulation form of the graphite powder is changed. Change, at this time, the graphite powder inside the processing tube 207 is still detected by the density detector. If it is still detected that the density value of the graphite powder is high at this time, the electric control push rod 210 is controlled to retract downward to the bottom end of the processing tube 207, and then the second disc 213 is continued to be controlled to slide upward along the inner wall of the processing tube 207 again, and hit the limit ring 214, and the graphite powder on its surface is bounced up, thereby changing its stacking form, thereby changing the way the graphite powder is stacked, and avoiding the situation where the density of the graphite powder is too high, resulting in a small surface gap after subsequent sintering.

[0051] When the density detector detects that the density of the graphite powder inside the processing tube 207 is lower than the preset value, it means that the particle size of the graphite powder falling into the processing tube 207 is large, and the distance between adjacent graphite powders is too large, so that the density of the graphite powder in the processing tube 207 is low. At this time, when the graphite powder is sintered, the gap on the surface of the graphite powder will be too large, thereby reducing its strength and wear resistance, so the following adjustments are made:

[0052] The electric control push rod 210 controls the second disc 213 to slide in the processing tube 207, and makes the surface of the second disc 213 contact and collide with the bottom of the limiting ring 214. During this process, the graphite powder on the second disc 213 will bounce upwards. At the same time, the electric control push rod 210 continues to control the second disc 213 to squeeze the limiting ring 214, so that the second disc 213 will be slightly deformed. Under the control of the electric control push rod 210, the deformed second disc 213 will pass through the limiting ring 214 and enter the upper end position of the processing tube 207. At the same time, when the second disc 213 After passing through the limiting ring 214, the first disc 212 follows and enters the upper end of the processing tube 207. At this time, the second disc 213 is controlled to slide upward along the inner wall of the processing tube 207, so that the surface of the second disc 213 contacts the bottom of the dispersion plate 205, and the graphite powder on the second disc 213 is squeezed with the bottom surface of the dispersion plate 205. After the graphite powder is squeezed, it will split, so as to achieve the effect of reducing the volume of the graphite powder. When the extrusion of the graphite powder is completed, the electric control push rod 210 is controlled to slide downward. When the bottom of the second disc 213 contacts the limiting ring 205, the graphite powder on the second disc 213 is squeezed. When the second disc 213 contacts the first disc 212, the second disc 213 will continue to deform at the edge of the second disc 213 under the pressure of the electric control push rod 210. After the deformed second disc 213 passes through the limit ring 214, the electromagnet 215 inside the first disc 212 is controlled to generate a magnetic attraction force on the second disc 213, so that the distance between the first disc 212 and the second disc 213 is shortened. In this process, the gas in the compression tube is squeezed by the first disc 212 and the second disc 213, and is discharged outward through the one-way air valve on the surface of the second disc 213. At this time, the discharged gas will push the second disc 213 The graphite powder on the surface is blown upwards, and at this time, the electric control push rod 210 continues to control the second disk 213 that overlaps with the first disk 212 to impact the limit ring 214 and vibrate the graphite powder, so that the graphite powder is blown outwards in coordination with the gas during the bouncing process, so that the graphite powder with smaller particle size will float in the air for a short time, and the graphite powder with larger particle size will first fall onto the surface of the second disk 213, and then the graphite powder with smaller particle size will gradually settle and fill in the gaps in the adjacent graphite powder, thereby improving the density of the graphite powder and achieving the effect of enhancing the strength and wear resistance of the graphite powder after sintering.

[0053] It is worth noting that: after the graphite powder is purified and falls onto the surface of the filter chamber 208 to form an extrusion blockage, the first disc 212 can be controlled to shrink downward by the electric push rod 210, so that the second disc 213 and the first disc 212 are moved out of the processing tube 207. At the same time, during the shrinkage process, the bottom of the driving block 211 is in contact with the filter chamber 208 to form an extrusion. When the surface of the filter chamber 208 is squeezed, it will be concave and deformed downward, and the gas in the filter chamber 208 will be ejected outward due to the squeezing. Part of the blocked graphite powder can be blown upward, and at the same time, the bottom of the driving block 211 is controlled to move upward by the electric control push rod 210, so that the bottom of the driving block 211 is no longer in contact with the surface of the filter bin 208. At this time, the filter bin 208 will quickly reset due to its own elasticity, and the graphite powder on its surface will be bounced upward during the reset process, so that the graphite powder will fall back into and pass through the filter bin 208 into the exhaust pipe 209, so that the filter bin 208 can be cleared by the cooperation of the filter bin 208 and the driving block 211.

[0054] The present invention also provides a method for using the graphitization purification system, and the specific steps of the method are as follows:

[0055] S1. First, turn on the controller to transport the graphite powder to be purified to the upper end of the processing component 2 through the feeding component 1, and at the same time control the feeding component 1 to break up the graphite powder and put the graphite powder into the bottom of the processing component 2;

[0056] S2, secondly, the heater is started by the controller, and the heater controls the processing component 2 to heat up, so that the graphite powder inside is evenly heated. However, the melting point of the impurities in the graphite powder is lower than that of the graphite powder, which will cause the impurities to be gasified and discharged to the outside through the exhaust pipe 202, thereby completing the purification process of the graphite powder;

[0057] S3. Finally, the purified graphite powder will enter the discharging component 3 through the bottom of the processing component 2, and then the controller drives the discharging component 3 to discharge the purified graphite powder to the outside.

[0058] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
