Description
Technical Field
[0001] The invention relates to the technical field of graphitization furnaces, and in particular to a graphitization device for preparing porous graphite. Background Art
[0002] A graphitization furnace is required in the preparation process of porous graphite. The working principle of the graphitization furnace is mainly based on the principle of resistance heating. High temperature is generated by resistance heating, induction heating, etc., and the temperature in the furnace is raised to the temperature range required for graphitization of carbon materials, thereby graphitizing the raw materials and preparing graphite.
[0003] When the graphite furnace is graphitizing the raw materials at high temperature, such as during the heating stage of the graphitization furnace, dusty gases are released, mainly graphite dust and other volatile organic compounds. These waste gases do not meet the emission standards and cannot be directly discharged into the air. The waste gases need to undergo a series of treatments until they meet the emission standards before they can be discharged into the environment. In order to treat these waste gases, the methods used include electrostatic capture, dry suction and incineration. The specific treatment process may include using suitable fans and filters to extract the generated dusty waste gases and filter them.
[0004] Since there are some impurities in the exhaust gas, some impurities will stick to the pipeline during the transmission process, which is difficult to handle. In the long run, the space inside the pipeline will become smaller, affecting the subsequent exhaust gas filtration. In addition, the traditional pipeline cleaning is more cumbersome and not simple enough, which puts a heavy burden on the staff, and the cleaning process will also affect the normal use of the graphitization furnace.
[0005] Therefore, the traditional graphitization furnace can be improved so that it can avoid the above-mentioned problems. Summary of the invention
[0006] The purpose of the present invention is to solve the above-mentioned problems and to provide a graphitization device for preparing porous graphite.
[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A graphitization device for preparing porous graphite, comprising: A furnace body, wherein a fixed pipe is fixed on the furnace body, and the fixed pipe is connected to a connecting pipe, and a filter screen is arranged in the connecting pipe; Side hole, the filter screen is provided with a side hole, and the bottom of the filter screen is abutted with a transfer tube, a push rod is fixed on the transfer tube, and the push rod passes through the side hole and the through hole provided on the connecting tube, and the push rod is connected with a screw sleeve through a thread; A vertical rod, a vertical hole is opened on the connecting pipe, and the vertical hole is slidably connected to the protruding part of the top of the vertical rod, a scraper is fixed on the vertical rod and is slidably connected to the inner wall of the connecting pipe, and a driving member is provided on the connecting pipe to drive the vertical rod and the scraper to rotate, so that the scraper cleans the impurities adhered to the inner wall of the connecting pipe.

[0009] Preferably, the adjusting member includes a circular groove on the vertical rod, and the circular groove is adapted to the corresponding groove on the stop block, a screw hole is provided on the stop block, and a screw groove corresponding to the screw hole is provided on the connecting pipe, and the screw hole and the screw groove are connected to a screw rod through a thread.
[0010] Preferably, the matching part includes a rotating block rotatably connected to the filter screen, and a polygonal groove is provided on the rotating block, a polygonal block matching the polygonal groove is fixed at the bottom of the vertical rod, an inclined rod is fixed at the bottom of the rotating block, and a fixed ball is fixed on the inclined rod, a sliding groove is provided in the transfer tube, and a side rod is fixed in the sliding groove, the side rod is slidably connected to the slider, and the slider is also slidably connected to the sliding groove, a spring is sleeved on the side rod, the spring pushes the slider to move downward, and a knocking ball matching the fixed ball is fixed on the slider.
[0011] Preferably, the rotation of the vertical rod drives the scraper and the rotating block to rotate, and the inclined rod and the fixed ball rotate, and the fixed ball collides with the knocking ball, causing the knocking ball to move upward and compress the spring until the knocking ball knocks on the filter screen, thereby freeing the filter screen and avoiding clogging of the filter screen.
[0012] Preferably, high temperature resistant sealing rings are provided on the upper and lower surfaces of the filter screen that are in contact with the connecting pipe and the transfer pipe.
[0013] Preferably, a ball bearing is provided on the portion where the circular groove contacts the corresponding groove.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present application is started by a motor, which causes the rotating rod to rotate, thereby driving the vertical rod to rotate. The scraper cleans the impurities adhered to the inner wall of the connecting pipe as the vertical rod rotates. When the vertical rod rotates, the rotating block will also rotate together, thereby driving the inclined rod and the fixed ball to rotate together. The fixed ball will abut against the knocking ball during rotation, thereby pushing the knocking ball upward and compressing the spring until the knocking ball hits the filter, causing the filter to vibrate, thereby preventing the filter from being blocked by impurities.
[0015] 2. In the present application, since multiple sliders and knocking balls are provided in the transfer tube, the fixed ball will contact the knocking balls at different positions in turn during rotation, causing the knocking balls at different positions to move up and collide with the filter. Therefore, different positions of the filter will vibrate, so that all parts of the filter can be prevented from being blocked. The knocking ball can better play the anti-blocking effect on the filter. After the knocking ball knocks the filter, it will move down and return to its original position under the elastic force of the spring, waiting for the next collision with the fixed ball. An elastic gasket is also provided on the part where the knocking ball contacts the filter. Therefore, when the knocking ball collides with the filter, it will not cause damage to the filter.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] See also Figure 1-Figure 5 , the present invention provides a technical solution: A graphitization device for preparing porous graphite, comprising: A furnace body 1, a fixed pipe 2 is fixed on the furnace body 1, and the fixed pipe 2 is connected to a connecting pipe 3, a filter screen 27 is arranged in the connecting pipe 3, and during the high-temperature graphitization process of the furnace body 1, the waste gas generated will pass through the fixed pipe 2 to reach the connecting pipe 3, and will be filtered by the filter screen 27 before being processed in the next step; The filter screen 27 is provided with a side hole 28, and the bottom of the filter screen 27 is abutted with the transfer tube 23, a push rod 24 is fixed on the transfer tube 23, and the push rod 24 passes through the side hole 28 and the through hole 25 provided on the connecting tube 3, and the push rod 24 is connected with the screw sleeve 26 by threading; the upper and lower surfaces of the filter screen 27 are provided with high temperature resistant sealing rings on the parts in contact with the connecting tube 3 and the transfer tube 23, so after the filter screen 27 abuts against the connecting tube 3 and the transfer tube 23, the exhaust gas leakage can be effectively avoided, so the filter screen 27 can stably exert the filtering effect; The vertical rod 5 and the connecting pipe 3 are provided with a vertical hole 4, and the vertical hole 4 is slidably connected to the protruding part of the top of the vertical rod 5. The vertical rod 5 is fixed with a scraper 7 that is slidably connected to the inner wall of the connecting pipe 3. The connecting pipe 3 is provided with a driving member that drives the vertical rod 5 and the scraper 7 to rotate, so that the scraper 7 cleans the impurities adhered to the inner wall of the connecting pipe 3. Since the connection between the vertical rod 5, the scraper 7 and the connecting pipe 3 adopts a detachable design, when impurities in the exhaust gas adhere to the scraper 7, the staff can regularly clean the scraper 7. The connecting pipe 3 is provided with an observation window, which can directly check the condition of the scraper 7 inside the connecting pipe 3, so that the staff can judge whether the scraper 7 needs to be cleaned.
[0019] Specifically, Figure 2 As shown, the driving member includes a bottom hole 1 21 and a bottom hole 22 opened on the connecting pipe 3, the bottom hole 1 21 is slidably connected to the clamping rod 19 fixed on the bracket 15, and the bottom hole 22 is threadedly connected to the rotating rod 20 rotatably connected to the bracket 15, a motor 16 is installed on the bracket 15, and the motor 16 drives the rotating rod 17 to rotate, a block 18 is fixed on the rotating rod 17, and a top groove 8 and a square groove 9 engaged with the rotating rod 17 and the block 18 are opened on the top of the vertical rod 5, the vertical rod 5 controls the vertical height with the cooperation of the adjusting member, and the vertical rod 5 also cooperates with the matching member to prevent the filter screen 27 from being blocked when the scraper 7 cleans the inner wall of the connecting pipe 3.
[0020] After the motor 16 is started, it can drive the rotating rod 17 to rotate, thereby driving the vertical rod 5 to rotate. The scraper 7 cleans the impurities adhered to the inner wall of the connecting pipe 3 as the vertical rod 5 rotates. The impurities scraped from the inner wall of the connecting pipe 3 will fall on the filter screen 27 and accumulate on the filter screen 27. Therefore, the filter screen 27 needs to be cleaned regularly to avoid excessive accumulation of impurities on the filter screen 27 affecting the filtering efficiency. Since the connection method between the filter screen 27 and the connecting pipe 3 and the transfer pipe 23 is relatively simple, the staff can quickly and easily disassemble the filter screen 27 and clean it.
[0021] Specifically, Figure 4 As shown, the adjusting member includes a circular groove 6 provided on the vertical rod 5, and the circular groove 6 is adapted to the corresponding groove 11 provided on the stop block 10, a screw hole 12 is provided on the stop block 10, and a screw groove 13 corresponding to the screw hole 12 is provided on the connecting pipe 3, and the screw hole 12 and the screw groove 13 are connected to the screw rod 14 through a thread. Ball bearings are provided on the contact portion between the circular groove 6 and the corresponding groove 11, so when the vertical rod 5 rotates, there will be no large friction between the vertical rod 5 and the stop block 10. The vertical rod 5 can rotate more smoothly with the rotating rod 17, so the vertical rod 5 and the scraper 7 can simply and effectively scrape off the impurities on the inner wall of the connecting pipe 3. The burden of the staff in cleaning the connecting pipe 3 is effectively reduced.
[0022] Specifically, Figure 4 As shown, the matching parts include a rotating block 29 rotatably connected to the filter 27, and a polygonal groove 30 is provided on the rotating block 29, a polygonal block 31 adapted to the polygonal groove 30 is fixed to the bottom of the vertical rod 5, an inclined rod 32 is fixed to the bottom of the rotating block 29, and a fixed ball 33 is fixed to the inclined rod 32, a slide groove 34 is provided in the transfer tube 23, and a side rod 35 is fixed in the slide groove 34, the side rod 35 is slidably connected to the slider 36, and the slider 36 is also slidably connected to the slide groove 34, a spring 37 is sleeved on the side rod 35, the spring 37 pushes the slider 36 to move downward, and a knocking ball 38 adapted to the fixed ball 33 is fixed to the slider 36.
[0023] The rotation of the vertical rod 5 drives the scraper 7 and the rotating block 29 to rotate, and the inclined rod 32 and the fixed ball 33 rotate, and the fixed ball 33 collides with the knocking ball 38, so that the knocking ball 38 moves upward and compresses the spring 37 until the knocking ball 38 knocks on the filter screen 27, so that the filter screen 27 is prevented from being blocked.
[0024] In summary, the assembly process provided in this embodiment is as follows: The top of the vertical rod 5 is extended out of the connecting tube 3 through the vertical hole 4, and then the corresponding groove 11 of the stop block 10 is fitted with the circular groove 6 on the vertical rod 5, and the screw hole 12 on the stop block 10 is aligned with the screw groove 13 on the connecting tube 3. The screw 14 is connected with the screw hole 12 and the screw groove 13 by threads, and the position of the vertical rod 5 is fixed.
[0025] Align the clamping rod 19 at one end of the bracket 15 with the bottom hole 1 21 , and connect the rotating rod 20 at the other end with the bottom hole 22 through threads until the clamping rod 19 is engaged with the bottom hole 1 21 , and the top groove 8 and the square groove 9 opened on the vertical rod 5 are engaged with the rotating rod 17 and the block 18 .
[0026] Put the side hole 28 on the filter screen 27 on the top rod 24 on the transfer tube 23 until the filter screen 27 abuts against the transfer tube 23. Adjust the position of the polygonal groove 30 on the rotating block 29 so that the polygonal groove 30 is aligned with the polygonal block 31 at the bottom of the vertical rod 5. Then the transfer tube 23 and the filter screen 27 can be connected to the connecting tube 3, that is, the top rod 24 passes through the through hole 25 on the connecting tube 3 until the filter screen 27 abuts against the connecting tube 3, and the polygonal block 31 is locked with the polygonal groove 30. Use the screw sleeve 26 to be threadedly connected to the top rod 24, so that the connecting tube 3, the filter screen 27 and the transfer tube 23 can be fixed as a whole.
[0027] The operation process is as follows: as the furnace body 1 continues to operate, the exhaust gas generated will pass through the fixed pipe 2 and reach the connecting pipe 3. Then the motor 16 starts, causing the rotating rod 17 to rotate, thereby driving the vertical rod 5 to rotate. The scraper 7 cleans the impurities adhering to the inner wall of the connecting pipe 3 as the vertical rod 5 rotates.
[0028] At the same time, the vertical rod 5 is rotating, and the rotating block 29 will also rotate with it, thereby driving the inclined rod 32 and the fixed ball 33 to rotate together. The fixed ball 33 will abut against the knocking ball 38 during rotation, thereby pushing the knocking ball 38 to move up and compressing the spring 37. Until the knocking ball 38 hits the filter 27, the filter 27 vibrates, thereby preventing the filter 27 from being blocked by impurities. Since a plurality of sliders 36 and knocking balls 38 are provided in the transfer tube 3, the fixed ball 33 will contact the knocking balls 38 at different positions in turn during rotation, thereby causing the knocking balls 38 at different positions to move up and collide with the filter 27. Therefore, different positions of the filter 27 will vibrate, so that all parts of the filter 27 can prevent blockage.
[0029] Since the exhaust gas passes through the fixed pipe 2 from the furnace body 1 to the connecting pipe 23 , impurities on the exhaust gas will also adhere to the scraper 7 , so the vertical rod 5 and the scraper 7 are designed to be detachable, and the scraper 7 can be removed from the connecting pipe 3 later.
[0030] The filter screen 27 is also detachably designed together with the connecting pipe 3 and the transfer pipe 23, so that it is convenient to clean the impurities accumulated on the filter screen 27 later.
[0031] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
