Description

Technical Field

[0001] This utility model relates to the field of carbon production technology, and in particular to a roasting furnace for carbon production. Background Technology

[0002] In the carbon production process, the roasting process is a key step that determines the performance of the final product. The high temperature generated by fuel combustion raises the temperature inside the furnace to the temperature required for carbon roasting. The carbon raw materials are gradually heated by high-temperature heat radiation and heat conduction inside the furnace, which evaporates the moisture and volatiles, ultimately forming a carbon product with specific physical and chemical properties (such as density, strength, and conductivity).

[0003] Currently, the industry generally adopts the operation method of directly piling carbon raw materials into the furnace body. This extensive piling method easily leads to uneven distribution of raw materials in the furnace. Some roasting furnaces are equipped with stirring devices, which drive the stirring blades to agitate the raw materials in the furnace. However, the design of the existing stirring structure has limitations. The stirring blades can only achieve a single rotational motion, and their range of action is limited to a plane area of ​​a fixed height. This causes material layers of different depths to remain relatively static, and the stirring effect is far from ideal. Utility Model Content

[0004] In view of the problems existing in the above and / or existing carbon production roasting furnaces, this utility model is proposed.

[0005] Therefore, the problem to be solved by this invention is how to address the fact that most stirring fan blades can only achieve a single rotational motion, and their effective range is limited to a planar area of ​​a fixed height.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1

[0032] Reference Figures 1-7 This is the first embodiment of the present invention, which provides a calcining furnace for carbon production, comprising:

[0033] The main structure 1 includes a furnace body 11, with a carbon bin 12 fixedly connected to the bottom of the furnace body 11; and,

[0034] The stirring assembly 2 includes a fixed box 21 fixedly connected to the top of the furnace body 11. A cam 22 is rotatably connected to the inner cavity of the fixed box 21. A movable rod 23 is rotatably connected to the surface of the cam 22. A movable plate 24 is rotatably connected to the bottom of the movable rod 23. A cylinder 25 is slidably connected to the surface of the movable plate 24. The top of the cylinder 25 is connected to the fixed box 21, and the bottom of the cylinder 25 is connected to the furnace body 11. A rotating shaft 26 is rotatably connected to the bottom of the movable plate 24 via a bearing. The bottom of the rotating shaft 26 passes through the cylinder 25 and is slidably connected to a drive rod 27. The drive rod 27 is fixedly connected to the bottom of the inner cavity of the furnace body 11. A drive element 28 is provided on one side of the drive rod 27. First stirring blades 29 are fixedly connected to both sides of the rotating shaft 26. Second stirring blades 30 are provided on both sides of the first stirring blades 29. A linkage element 31 is provided on the top of the second stirring blades 30.

[0035] The furnace body 11 provides space for roasting, while the carbon bin 12 is used for fuel combustion and heating. The fixed box 21 supports the cam 22 and the motor 22-1. The rotation of the cam 22 drives the movable plate 24 to slide inside the cylinder 25 via the movable rod 23, so that the rotating shaft 26 can be raised and lowered. The rotating shaft 26 cooperates with the drive rod 27 to rotate via the drive component 28 while raising and lowering, which drives the first stirring blade 29 to both rotate and rise and fall, thereby expanding the stirring range. The linkage component 31 makes the second stirring blade 30 rotate with the rotating shaft 26 to stir the raw materials on both sides of the inner cavity of the furnace body 11, making up for the stirring dead corner of the first stirring blade 29.

[0036] During actual descent, if the raw material accumulates below the first stirring blade 29, it may become stuck due to excessive resistance. To address this, the first stirring blade 29 is designed with tilted blades. During descent, its rotation direction and the tilt angle of the blades create a downward thrust, which disperses the raw material accumulated below and reduces the risk of jamming. A bellows is fixed to the lower half of the surface of the rotating shaft 26, which covers the surface of the drive rod 27. The bottom is rotatably connected to the bottom of the furnace body 11 through a bearing, and the end of the first stirring blade 29 passes through the bellows. This structure not only provides a closed protection for the drive block 28-1 and the drive groove 28-2, preventing carbon raw materials from entering the gap and affecting the transmission, but also prevents raw materials from accumulating at the bottom of the rotating shaft 26, thus providing unobstructed space for the lifting and lowering of the rotating shaft 26.

[0037] Example 2

[0038] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the linkage 31 includes a first gear 31-1 sleeved on the surface of the rotating shaft 26, toothed plates 31-2 meshing on both sides of the first gear 31-1, a second gear 31-3 meshing on the surface of the toothed plates 31-2, a connecting shaft 31-4 fixedly connected to the inner cavity of the second gear 31-3, the surface of the connecting shaft 31-4 fixedly connected to the second stirring blade 30, and the top of the connecting shaft 31-4 rotatably connected to the inner cavity of the furnace body 11.

[0040] The first gear 31-1 rotates with the rotating shaft 26, which drives the two side gear plates 31-2 to move. The gear plates 31-2 drive the second gear 31-3 to rotate, which causes the connecting shaft 31-4 to drive the second stirring blade 30 to rotate. Thus, the second stirring blade 30 and the first stirring blade 29 work together to cover the two sides of the inner cavity of the furnace body 11, thereby solving the problem of the limited range of action of a single stirring blade and improving the uniformity of raw material mixing.

[0041] Specifically, the inner wall of the first gear 31-1 is provided with a keyway 31-5, and the surface of the rotating shaft 26 is fixedly connected with a key tooth 31-6, which cooperates with the keyway 31-5.

[0042] The keyway 31-5 and the key teeth 31-6 cooperate to ensure that the first gear 31-1 rotates synchronously with the rotating shaft 26 while allowing the rotating shaft 26 to rise and fall. The key teeth 31-6 are embedded in the keyway 31-5 to transmit torque to make the first gear 31-1 rotate. At the same time, the rising and falling of the rotating shaft 26 will not affect the gear transmission, thereby ensuring that the linkage 31 continues to work during the rising and falling of the rotating shaft 26 and maintaining the stirring action of the second stirring blade 30.

[0043] Specifically, there are multiple sets of keyways 31-5, which are evenly distributed on the inner wall of the first gear 31-1.

[0044] By increasing the number of keyways 31-5, the torque transmission is made more uniform, avoiding damage caused by excessive force on a single keyway, thereby ensuring the transmission reliability between the first gear 31-1 and the rotating shaft 26 and extending the service life of the linkage 31.

[0045] Specifically, a support cylinder 31-7 is sleeved on the surface of the rotating shaft 26. The top of the support cylinder 31-7 is fixedly connected to the first gear 31-1. A limiting plate 31-8 is rotatably connected to the surface of the support cylinder 31-7. One side of the limiting plate 31-8 is fixedly connected to the inner cavity of the furnace body 11.

[0046] The support cylinder 31-7 and the limiting plate 31-8 provide support for the first gear 31-1, thereby ensuring that the first gear 31-1 always meshes precisely with the toothed plate 31-2, thus avoiding transmission failure due to gear misalignment and ensuring the stable operation of the second stirring blade 30.

[0047] Specifically, a slider 31-9 is fixedly connected to the top of the toothed plate 31-2, and a groove 31-10 is opened on the top of the inner cavity of the furnace body 11, which cooperates with the slider 31-9.

[0048] The slider 31-9 is slidably engaged in the inner cavity of the slide groove 31-10. The slider 31-9 and the slide groove 31-10 cooperate to guide the movement of the toothed plate 31-2. When the toothed plate 31-2 moves, the slider 31-9 slides along the slide groove 31-10 to prevent the toothed plate 31-2 from deviating or tilting, and to ensure that it always maintains a meshing state with the first gear 31-1 and the second gear 31-3, thereby ensuring the stability of the transmission of the linkage 31.

[0049] Specifically, the driving component 28 includes a driving block 28-1 fixedly connected to one side of the driving rod 27, and a driving groove 28-2 is formed on the surface of the rotating shaft 26.

[0050] The drive block 28-1 on one side of the drive rod 27 is embedded in the drive groove 28-2 of the rotating shaft 26. When the rotating shaft 26 rises and falls, the drive block 28-1 contacts the inclined surface of the drive groove 28-2, forcing the rotating shaft 26 to rotate around its own axis, so that the first stirring blade 29 can simultaneously rotate and rise and fall, thus expanding the stirring range.

[0051] Specifically, a ball bearing 28-3 is rotatably connected to one side of the drive block 28-1 and engages with the drive groove 28-2.

[0052] When the ball bearing 28-3 rolls in contact with the drive block 28-1 and the drive groove 28-2, it can reduce the resistance of the relative motion between the two, making the rotation of the rotating shaft 26 smoother, thereby reducing component wear and extending the service life of the drive component 28.

[0053] Specifically, one side of the carbon bin 12 is open, and the surface of the carbon bin 12 is provided with a closed door 12-1 that matches the open side.

[0054] The sealing door 12-1 is used to seal the opening of the carbon bin 12 and control the combustion environment inside the carbon bin 12. Closing the sealing door 12-1 can adjust the air flow inside the carbon bin 12, control the fuel combustion intensity, and thus adjust the temperature inside the furnace body 11 to ensure that the carbon raw materials are roasted at a suitable temperature and improve product quality.

[0055] Specifically, a motor 22-1 is fixedly connected to one side of the fixed box 21. The output shaft of the motor 22-1 passes through the fixed box 21 and is fixedly connected to the cam 22.

[0056] The output shaft of motor 22-1 drives cam 22 to rotate. Through the cooperation of cam 22 and movable rod 23, the rotational motion is converted into linear motion of movable plate 24, thereby providing power for the lifting and lowering of rotating shaft 26 and ensuring continuous operation of stirring assembly 2.

[0057] When in use, carbon raw materials are placed into the furnace body 11, then the fuel in the carbon bin 12 is ignited, and then the combustion intensity is adjusted by closing the sealing door 12-1.

[0058] Then, the motor 22-1 on one side of the fixed box 21 is started. Its output shaft drives the cam 22 to rotate. The cam 22 pushes the movable rod 23, which in turn drives the movable plate 24 to slide up and down inside the cylinder 25. The movable plate 24 drives the rotating shaft 26 to rise and fall along the drive rod 27. During the rising and falling of the rotating shaft 26, the drive block 28-1 on one side of the drive rod 27 contacts the drive groove 28-2 through the ball 28-3, forcing the rotating shaft 26 to rotate, thereby driving the first stirring blade 29 to both rotate and rise and fall, stirring the raw materials in the middle of the furnace body 11.

[0059] Simultaneously, when the rotating shaft 26 rotates, the key teeth 31-6 on its surface drive the first gear 31-1 to rotate through the keyway 31-5, thereby driving the first gear 31-1 to drive the two side gear plates 31-2 to move, which in turn causes the gear plates 31-2 to drive the second gear 31-3 to rotate, causing the connecting shaft 31-4 to drive the second stirring blade 30 to rotate, thus stirring the raw materials on both sides of the inner cavity of the furnace body 11.

[0060] Thus, the coordinated action of the first stirring blade 29 and the second stirring blade 30 can achieve uniform stirring of raw materials at different depths and positions in the furnace, so that the raw materials are heated evenly and the roasting process is completed.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
