Description

Technical Field

[0001] The present invention relates to the technical field of graphitization furnaces, and in particular to a graphitization device for preparing porous graphite. Background Art

[0002] During the preparation of porous graphite, a graphitization furnace is required. The working principle of the graphitization furnace is mainly based on the principle of resistance heating. High temperature is generated through resistance heating, induction heating, etc., and the temperature inside the furnace is raised to the temperature range required for graphitizing carbon materials, so that the raw materials are graphitized, and then graphite is prepared.

[0003] Since the graphitization furnace releases dust-containing gases during the high-temperature graphitization treatment of raw materials, such as during the heating stage of the graphitization furnace, which mainly contain graphite dust and other volatile organic compounds, these waste gases do not meet the emission standards and thus cannot be directly discharged into the air. The waste gases need to undergo a series of treatments until they meet the emission standards before being discharged into the environment. To treat these waste gases, methods such as electrocapture, dry absorption, and incineration are adopted. The specific treatment process may include using a suitable fan and filter to draw away the generated dust waste gas and perform filtration treatment.

[0004] Since there are some impurities mixed in the waste gases, during the process of pipeline transmission, some impurities will adhere to the pipeline and are difficult to handle. Over time, this will cause the internal space of the pipeline to become smaller, affecting the subsequent waste gas filtration. Moreover, the traditional pipeline cleaning is rather cumbersome, not simple enough, imposing a large 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 to avoid the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a graphitization device for preparing porous graphite in order to solve the above problems.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A graphitization device for preparing porous graphite, comprising:

[0009] A furnace body, a fixed pipe is fixed on the furnace body, and the fixed pipe is connected to a connecting pipe, and a filter screen is provided in the connecting pipe;

[0010] Side holes, side holes are opened on the filter screen, and a transfer pipe is abutted against the bottom of the filter screen. A top rod is fixed on the transfer pipe, and the top rod penetrates through the side holes and the through holes opened on the connecting pipe. The top rod is threadedly connected with a screw sleeve;

[0011] A vertical rod, a vertical hole is provided on the connecting pipe, and the protruding part at the top of the vertical rod is slidably connected to the vertical hole. A scraping plate slidably connected to the inner wall of the connecting pipe is fixed on the vertical rod. A driving member is provided on the connecting pipe to drive the vertical rod and the scraping plate to rotate, so that the scraping plate cleans the impurities adhered to the inner wall of the connecting pipe.

[0012] Preferably, the driving member includes a first bottom hole and a second bottom hole provided on the connecting pipe. The first bottom hole is slidably connected to a clamping rod fixed on the bracket, and the second bottom hole is threadedly connected to a rotating rod rotatably connected to the bracket. A motor is installed on the bracket, and the motor drives the rotating rod to rotate. A square block is fixed on the rotating rod, and a top groove and a square groove adapted to the rotating rod and the square block are provided at the top of the vertical rod. The vertical rod controls the vertical height under the cooperation of an adjusting member, and the vertical rod also cooperates with a cooperating member to prevent the filter screen from being blocked when the scraping plate cleans the inner wall of the connecting pipe.

[0013] Preferably, the adjusting member includes a circular groove provided on the vertical rod, and the circular groove is adapted to a corresponding groove provided on the abutting block. A threaded hole is provided on the abutting block, and a threaded groove corresponding to the threaded hole is provided on the connecting pipe. The threaded hole and the threaded groove are threadedly connected with a screw rod.

[0014] Preferably, the cooperating member includes a rotating block rotatably connected to the filter screen, and a polygonal groove is provided on the rotating block. A polygonal block adapted to 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 adapter pipe, and a side rod is fixed in the sliding groove. The side rod is slidably connected to a slider, and the slider is also slidably connected to the sliding groove. A spring is sleeved on the side rod, and the spring pushes the slider to move downward. A knocking ball adapted to the fixed ball is fixed on the slider.

[0015] Preferably, when the vertical rod rotates to drive the scraping plate and the rotating block to rotate, 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, so as to avoid blocking of the filter screen.

[0016] Preferably, high-temperature resistant sealing rings are provided on the parts of the upper and lower surfaces of the filter screen that contact the connecting pipe and the adapter pipe.

[0017] Preferably, balls are provided on the parts where the circular groove contacts the corresponding groove.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are:

[0019] 1. The present application starts the motor, causing the rotating rod to rotate, thereby driving the vertical rod to rotate. The scraper rotates with the vertical rod and cleans the impurities adhering to the inner wall of the connecting pipe. During the rotation of the vertical rod, the rotating block also rotates accordingly, driving the inclined rod and the fixed ball to rotate together. During the rotation of the fixed ball, it contacts the knocking ball, pushing the knocking ball upward and compressing the spring until the knocking ball strikes the filter screen, causing the filter screen to vibrate, thereby preventing the filter screen from being blocked by impurities.

[0020] 2. Since there are multiple sliders and knocking balls in the adapter pipe in the present application, during the rotation of the fixed ball, it will sequentially contact the knocking balls at different positions, resulting in the upward movement and collision with the filter screen of the knocking balls at different positions. Therefore, different positions of the filter screen will vibrate, enabling all parts of the filter screen to prevent blockage. The knocking balls can better play the role of preventing blockage of the filter screen. After the knocking balls strike the filter net, they will move downward under the elastic force of the spring and return to their original positions, waiting to collide with the fixed ball next time. An elastic gasket is also provided on the part of the knocking ball that contacts the filter screen. Therefore, when the knocking ball collides with the filter screen, it will not cause damage to the filter screen. Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0030] A graphitization device for preparing porous graphite, comprising:

[0031] 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 provided in the connecting pipe 3. During the high-temperature graphitization process of the furnace body 1, the waste gas generated will pass through the fixed pipe 2 and reach the inside of the connecting pipe 3, and after being filtered by the filter screen 27, it will be processed in the next step;

[0032] Side holes 28 are provided on the filter screen 27. A rotary joint pipe 23 is abutted against the bottom of the filter screen 27. A top rod 24 is fixed on the rotary joint pipe 23, and the top rod 24 penetrates through the side holes 28 and the through holes 25 provided on the connecting pipe 3. The top rod 24 is threadedly connected with a screw sleeve 26; High-temperature resistant sealing rings are provided on the upper and lower surfaces of the filter screen 27 in contact with the connecting pipe 3 and the rotary joint pipe 23. Therefore, after the filter screen 27 abuts against the connecting pipe 3 and the rotary joint pipe 23, the leakage of waste gas can be effectively avoided, so the filter screen 27 can stably play the filtering effect;

[0033] The vertical rod 5, the connecting pipe 3 is provided with a vertical hole 4, and the vertical hole 4 is slidably connected to the protruding part at the top of the vertical rod 5. A scraping plate 7 slidably connected to the inner wall of the connecting pipe 3 is fixed on the vertical rod 5. The connecting pipe 3 is provided with a driving member for driving the vertical rod 5 and the scraping plate 7 to rotate, so that the scraping plate 7 cleans the impurities adhered to the inner wall of the connecting pipe 3. Since the connection between the vertical rod 5 and the scraping plate 7 and the connecting pipe 3 adopts a detachable design, when impurities in the waste gas adhere to the scraping plate 7, the staff can clean the scraping plate 7 regularly. The connecting pipe 3 is provided with an observation window, through which the situation of the scraping plate 7 inside the connecting pipe 3 can be directly viewed, which is convenient for the staff to judge whether the scraping plate 7 needs to be cleaned.

[0034] Specifically, as Figure 2 shown, the driving member includes a bottom hole one 21 and a bottom hole two 22 opened on the connecting pipe 3. The bottom hole one 21 is slidably connected to a clamping rod 19 fixed on the bracket 15. The bottom hole two 22 is threadedly connected to a 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 square block 18 is fixed on the rotating rod 17, and a top groove 8 and a square groove 9 for engaging with the rotating rod 17 and the square block 18 are opened at the top of the vertical rod 5. The vertical rod 5 controls its vertical height under the cooperation of the adjusting member, and the vertical rod 5 also cooperates with the cooperating member to prevent the filter screen 27 from being blocked when the scraping plate 7 cleans the inner wall of the connecting pipe 3.

[0035] After the motor 16 is started, it can drive the rotating rod 17 to rotate, thereby driving the vertical rod 5 to rotate. The scraping plate 7 rotates with the vertical rod 5 to clean the impurities adhered to the inner wall of the connecting pipe 3. The impurities scraped off 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 impurities accumulated on the filter screen 27 affecting the filtration efficiency. Since the connection method of the filter screen 27 with the connecting pipe 3 and the adapter pipe 23 is relatively simple, the staff can quickly and simply disassemble the filter screen 27 from it for cleaning.

[0036] Specifically, as Figure 4 shown, the adjusting member includes a circular groove 6 opened on the vertical rod 5, and the circular groove 6 is adapted to a corresponding groove 11 opened on the abutting block 10. A threaded hole 12 is opened on the abutting block 10, and a threaded groove 13 corresponding to the threaded hole 12 is opened on the connecting pipe 3. A screw rod 14 is threadedly connected to the threaded hole 12 and the threaded groove 13. Ball bearings are provided on the part where the circular groove 6 contacts the corresponding groove 11. Therefore, when the vertical rod 5 rotates, there will be no large frictional force between the vertical rod 5 and the abutting block 10. The vertical rod 5 can rotate more smoothly when rotating with the rotating rod 17. Therefore, the vertical rod 5 and the scraping plate 7 can simply and effectively scrape off the impurities on the inner wall of the connecting pipe 3. Effectively reducing the burden on the staff to clean the connecting pipe 3.

[0037] Specifically, as Figure 4As shown in the figure, the fitting includes a rotating block 29 rotatably connected to the filter screen 27. A polygonal groove 30 is formed in 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 sliding groove 34 is formed in the rotating connection pipe 23, and a side rod 35 is fixed in the sliding groove 34. The side rod 35 is slidably connected to a slider 36, and the slider 36 is also slidably connected to the sliding groove 34. A spring 37 is sleeved on the side rod 35, and the spring 37 pushes the slider 36 to move downward. A knocking ball 38 adapted to the fixed ball 33 is fixed to the slider 36.

[0038] When the vertical rod 5 rotates to drive the scraper 7 and the rotating block 29 to rotate, the inclined rod 32 and the fixed ball 33 rotate. The fixed ball 33 collides with the knocking ball 38, causing the knocking ball 38 to move upward and compress the spring 37 until the knocking ball 38 knocks on the filter screen 27, so as to prevent the filter screen 27 from being blocked.

[0039] In summary, the assembly process provided in this embodiment is as follows:

[0040] The top of the vertical rod 5 is extended through the vertical hole 4 of the connecting pipe 3. Subsequently, the corresponding groove 11 of the abutting block 10 can be fitted with the circular groove 6 on the vertical rod 5, and the threaded hole 12 formed in the abutting block 10 is aligned with the threaded groove 13 formed in the connecting pipe 3. The screw rod 14 is threadedly connected to the threaded hole 12 and the threaded groove 13, so that the position of the vertical rod 5 is fixed.

[0041] Align the clamping rod 19 at one end of the bracket 15 with the bottom abutting hole one 21, and thread the rotating rod 20 at the other end with the bottom hole two 22 until the clamping rod 19 is engaged with the bottom abutting hole one 21, and the top groove 8 and the square groove 9 formed in the vertical rod 5 are engaged with the rotating rod 17 and the square block 18.

[0042] The side hole 28 on the filter screen 27 is sleeved on the top rod 24 on the rotating connection pipe 23 until the filter screen 27 abuts against the rotating connection pipe 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. Subsequently, the rotating connection pipe 23 and the filter screen 27 can be connected to the connecting pipe 3, that is, the top rod 24 penetrates through the through hole 25 on the connecting pipe 3 until the filter screen 27 abuts against the connecting pipe 3, and the polygonal block 31 is engaged with the polygonal groove 30. Thread the screw sleeve 26 with the top rod 24, and the connecting pipe 3, the filter screen 27 and the rotating connection pipe 23 can be fixed as a whole.

[0043] The operation process is as follows: As the furnace body 1 continues to operate, the generated waste gas will pass through the fixed pipe 2 and reach the inside of the connecting pipe 3. Then the motor 16 is started, causing the rotating rod 17 to rotate, thereby driving the vertical rod 5 to rotate. The scraper 7 rotates with the vertical rod 5 to clean the impurities adhering to the inner wall of the connecting pipe 3.

[0044] Meanwhile, during the rotation of the vertical rod 5, the rotating block 29 will also rotate accordingly, thereby driving the inclined rod 32 and the fixed ball 33 to rotate together. During the rotation, the fixed ball 33 will abut against the knocking ball 38, thereby pushing the knocking ball 38 upward and compressing the spring 37. Until the knocking ball 38 strikes the filter screen 27, causing the filter screen 27 to vibrate, thus preventing the filter screen 27 from being blocked by impurities. Since there are multiple sliders 36 and knocking balls 38 in the rotating connection pipe 3, during the rotation of the fixed ball 33, it will successively contact the knocking balls 38 at different positions, resulting in the upward movement of the knocking balls 38 at different positions and their collision with the filter screen 27. Therefore, different positions of the filter screen 27 will vibrate, enabling each part of the filter screen 27 to prevent blockage.

[0045] Since the waste gas passes from the furnace body 1 through the fixed pipe 2 to the connection pipe 23, the impurities in the waste gas will also adhere to the scraper 7. Therefore, the vertical rod 5 and the scraper 7 are designed to be detachable, and the scraper 7 can be removed from the connection pipe 3 subsequently.

[0046] The filter screen 27 is also detachably designed with the connection pipe 3 and the rotating connection pipe 23, which is convenient for cleaning the impurities accumulated on the filter screen 27 subsequently.

[0047] 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 obvious to those skilled in the art, and the general principles defined herein can 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 these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
