Technical Field
[0001] This invention relates to the field of sintering furnace technology, and more specifically, to a continuous hard carbon anode material sintering furnace and its method of use. Background Technology
[0002] A vacuum sintering furnace is a furnace used for protective sintering of heated materials in a vacuum environment. It employs various heating methods, such as resistance heating, induction heating, and microwave heating. Vacuum sintering furnaces utilize induction heating for protective sintering of heated materials and can be categorized into power frequency, medium frequency, and high frequency types. They can be classified as a subcategory of vacuum sintering furnaces. Vacuum induction sintering furnaces are complete sets of equipment that sinter cemented carbide cutting tools and various metal powder pressed bodies using the principle of medium frequency induction heating under vacuum or protective atmosphere conditions. They are designed for the industrial production of cemented carbide, dysprosium metal, and ceramic materials.
[0003] Chinese patent CN201410131182.6 discloses a vertical sintering furnace, comprising a furnace body with an inner wall covered with heat-insulating material and a heating channel. The heating channel is located within a furnace chamber that runs vertically through the furnace body, with the upper end serving as a feed inlet and the lower end as a discharge outlet. A support fixture for loading green magnetic core blanks to be sintered is neatly arranged vertically within the heating channel for sintering. A discharge device is located below the furnace body, comprising a carrier plate and a lifting mechanism. Slide rails are symmetrically arranged on both sides of the discharge outlet, with baffles connected to the rails. A column is fixed to the bottom of each slide rail, and the carrier plate is fitted onto the column. This invention effectively shortens the firing time, improves sintering efficiency, saves energy, and reduces production costs by repeatedly utilizing heat from bottom to top.
[0004] However, in current sintering equipment, after sintering is completed, the hard carbon anode material that has been sintered needs to be manually removed by the staff. Since the hard carbon anode material that has just been sintered is at a high temperature, it is very inconvenient for the staff to handle it, and there is also a risk of burns. Therefore, this invention proposes a continuous hard carbon anode material sintering furnace to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a continuous hard carbon anode material sintering furnace, comprising a sintering furnace mechanism, wherein a lifting mechanism is fixedly connected to the bottom of the sintering furnace mechanism, and a power mechanism is fixedly installed on the top of the lifting mechanism;

[0008] Each of the supporting threaded rods has a limiting sleeve rotatably mounted on its outer wall. The outer wall of the limiting sleeve is hinged to a first support. A second support is hinged to one side of the first support. A threaded sleeve that meshes with the supporting threaded rod is hinged to one side of the second support. A limiting groove is hinged to the side of the second support away from the threaded sleeve. A slider is provided on the top of the first base. The limiting groove is slidably installed in the inner cavity of the slider. A balancing support block is hinged to the side of the first support away from the limiting sleeve.

[0010] In a preferred embodiment, the top and bottom of the inner sintered shell are both open, and a plurality of microwave generators are arranged in a ring-shaped, equidistant manner on the inner wall of the inner sintered shell.
[0011] In a preferred embodiment, a limiting groove is provided on the top of the first base, and a connecting type rotating seat that is fixedly connected to the limiting sleeve is rotatably installed on the top of the first support. A plurality of supporting threaded rods are arranged in a ring-shaped and equidistant manner around the bottom of the outer insulation shell, and the plurality of supporting threaded rods are set in a one-to-one correspondence with the balance lifting block.
[0012] In a preferred embodiment, the outer circumferential diameter of the second sealing plate is less than the diameter of the bottom opening of the inner sintered shell, and the length between the outer circumferences of the first sealing plate is greater than the length between the circumferences at the bottom opening of the inner sintered shell.
[0013] In a preferred embodiment, the ventilation mechanism includes a first gas chamber connected to the top opening of the inner sintering shell. The first gas chamber has multiple through-type gas outlet slots inside. A connecting threaded rod is rotatably installed inside the first gas chamber, and a third sealing plate engages with the outer wall of the connecting threaded rod.
[0014] In a preferred embodiment, a support block is rotatably mounted at the bottom of the connecting threaded rod, a plurality of support frames fixedly mounted on the outer wall of the support block and fixedly connected to the annular support plate, and a hydraulic telescopic rod fixedly mounted on the top of the annular support plate and fixedly connected to the third sealing plate.
[0015] In a preferred embodiment, a support-type rotating shaft is rotatably mounted inside the support sleeve, and a stepper motor for driving the support-type rotating shaft to rotate is fixedly mounted inside the support sleeve. A first gear is fixedly connected to the top of the support-type rotating shaft, and a second gear is fixedly connected to one end of the connecting threaded rod extending from the top of the first air chamber. A first synchronous belt meshes with the outer walls of both the first gear and the second gear.
[0016] In a preferred embodiment, a third gear is fixedly connected to one end of the supporting shaft that passes through the first base, and a plurality of supporting threaded rods pass through the bottom of the first base, and a fourth gear is fixedly connected to the bottom of each of the plurality of supporting threaded rods.

The outer walls of the fifth gears provided on the outer walls of every two adjacent supporting threaded rods mesh with a third synchronous belt.
[0017] In a preferred embodiment, the heat recovery mechanism includes a second air chamber fixedly installed on the outer wall of the first air chamber. The second air chamber is interconnected with the inner cavity of the first air chamber through an air outlet groove. The outer wall of the second air chamber is provided with a plurality of vent pipes. One end of each of the plurality of vent pipes is connected to a third air chamber. The plurality of third air chambers are fixedly installed inside the inner sintering shell and the outer insulation shell. The side of each third air chamber extending into the inner cavity of the inner sintering shell is connected to a diffuser chamber. A valve controller for controlling the ventilation of the diffuser chamber is fixedly installed at the connection between the third air chamber and the diffuser chamber.
[0018] In a preferred embodiment, the method of using a continuous hard carbon anode material sintering furnace includes the following specific steps:
[0019] The first step is to place the material to be sintered on the support-type mesh plate. Then, drive the stepper motor inside the support-type sleeve to rotate so that the support-type rotating shaft rotates synchronously. This causes the first gear to drive the second gear through the first synchronous belt, which in turn causes the connecting threaded rod to rotate. Simultaneously, the support-type rotating shaft drives the third gear to rotate, which in turn drives multiple support-type threaded rods to rotate. This allows the third sealing plate to move down on the outer wall of the connecting threaded rod and gradually move towards the support block to seal the connection between the inner sintering shell and the microwave generator.
[0020] The second step involves the rotating support-type threaded rod causing multiple corresponding and intersecting first and second supports to deflect, which in turn causes the height of the first and second sealing plates to rise steadily until the support-type mesh plate extends the material into the interior of the inner sintering shell, and the first and second sealing plates double-seal the bottom of the inner sintering shell. Then, the microwave generator can be started to perform sintering treatment in the inner cavity of the inner sintering shell.
[0021] The third step is to reverse the stepper motor inside the synchronous drive support sleeve after sintering, so that the connecting threaded rod and the supporting threaded rod will reverse synchronously, and then the third sealing plate will gradually move upward and the supporting mesh plate will gradually move downward. When the third sealing plate moves to the air outlet groove, the hot air in the inner cavity of the inner sintering shell can be discharged first.
[0022] The fourth step is to store the hot air discharged through the air outlet through the air pipe in the inner cavity of the third air chamber. When the material is sintered again in the future, the hot air in the inner cavity of the third air chamber is circulated into the inner cavity of the inner sintering shell through the air diffuser by activating the valve controller to preheat the inner cavity of the inner sintering shell, so that it can be sintered again for use.
[0023] The technical effects and advantages of this invention are as follows:
[0024] 1. This invention provides a first sealing plate, a second sealing plate, and a supporting mesh plate that can move up and down at the bottom of the inner sintering shell. As the first sealing plate, the second sealing plate, and the supporting mesh plate descend as a whole, the sintered material has a certain buffer time to cool down naturally. At the same time, it avoids the problem of the high temperature making it inconvenient to handle and burns to workers when directly taking out the sintered material from the high-temperature inner cavity of the inner sintering shell, making it safer to use.
[0025] 2. The present invention makes the outer circumferential diameter of the second sealing plate smaller than the diameter of the bottom opening of the inner sintered shell, and the length between the outer circumferences of the first sealing plate is greater than the length between the circumferences at the bottom opening of the inner sintered shell. This allows the second sealing plate to initially seal the opening of the inner sintered shell after the first sealing plate, the second sealing plate, and the supporting mesh plate are lifted upward into the inner cavity of the inner sintered shell, and the first sealing plate to seal the bottom opening of the inner sintered shell again. This achieves a double sealing effect on the bottom opening of the inner sintered shell.
[0026] 3. The present invention sets up a connecting threaded rod that can rotate synchronously with the supporting threaded rod, and sets a third sealing plate that can move up and down on its outer wall to open and close the gas outlet groove. This allows the gas outlet groove to be exposed synchronously during the process of driving the first sealing plate and the second sealing plate to descend as a whole, thereby allowing the hot air in the inner cavity of the inner sintering shell to circulate out. This avoids the problem of hot air hitting the workers and burning them when the furnace door is opened to take out materials in the traditional way.
[0027] 4. The present invention provides a heat recovery mechanism for recovering stored heat gas by connecting it to the outer wall of the first gas chamber. This allows the stored heat gas to be simultaneously circulated into the inner cavity of the inner sintering shell before subsequent continuous sintering of materials. This preheats the inner cavity of the inner sintering shell, and then, in conjunction with the heating of the microwave generator, the temperature of the inner cavity of the inner sintering shell can be rapidly increased. This effectively improves heat utilization, shortens sintering time, increases sintering efficiency, saves energy, and is more convenient for practical use. Attached Figure Description

Detailed Implementation
[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Refer to the instruction manual appendix Figure 1-10 An embodiment of the present invention provides a continuous hard carbon anode material sintering furnace, such as... Figure 1 As shown, it includes a sintering furnace mechanism 1, a lifting mechanism 2 is fixedly connected to the bottom of the sintering furnace mechanism 1, and a power mechanism 5 is fixedly installed on the top of the lifting mechanism 2.
[0041] Reference Figure 3-4As shown, the sintering furnace mechanism 1 includes an inner sintering shell 101, an outer insulation shell 102 fixedly installed on the outer wall of the inner sintering shell 101, multiple microwave generators 103 fixedly installed on the inner wall of the inner sintering shell 101, and an annular support plate 104 fixedly installed on the top of the inner sintering shell 101. The lifting mechanism 2 includes multiple support-type threaded rods 21 rotatably installed on the bottom of the outer insulation shell 102, a first base 22 rotatably installed on the bottom of each of the multiple support-type threaded rods 21, and a second base 22 fixedly installed on the bottom of the first base 22. The support 23 and the power mechanism 5 include a support sleeve 51 fixedly installed on the top of the first base 22. The support sleeve 51 is fixedly installed on the outer wall of the outer insulation shell 102. In actual use, the first base 22 and the second base 23 are fixed, and the support threaded rod 21 can rotate on the top of the first base 22. In combination with the limiting of the support sleeve 51 on the outer insulation shell 102, multiple support threaded rods 21 can synchronously support the inner sintered shell 101 and the outer insulation shell 102 as a whole.
[0042] Combination Figure 4 As shown, a series of support-type threaded rods 21 are rotatably mounted on their outer walls, with a first support 25 hinged to the outer wall of each support 24. A second support 26 is hinged to one side of the first support 25, and the first and second supports 25 are arranged in a cross configuration. A threaded sleeve 27 that engages with the support-type threaded rod 21 is hinged to one side of the second support 26, and a limit groove 213 is hinged to the side of the second support 26 away from the threaded sleeve 27. A slider is provided on the top of the first base 22. 214. The limiting groove 213 is slidably installed in the inner cavity of the slider 214. Under normal conditions, the threaded sleeve 27 moves and stops at the bottom of the outer wall of the supporting threaded rod 21 and is close to the limiting sleeve 24. At this time, the angle between the first support 25 and the second support 26 is relatively large, and the limiting groove 213 slides away from the supporting threaded rod 21 in the inner cavity of the slider 214. At this time, the first sealing plate 28 and the second sealing plate 29 are completely stopped at the bottom of the inner sintered shell 101. Figure 7As shown, a balancing support block 212 is hinged to the side of the first support 25 away from the limiting sleeve 24. A first sealing plate 28, which is horizontally arranged, is fixedly installed on the top of the balancing support block 212. A second sealing plate 29 is fixedly installed on the top of the first sealing plate 28. A support frame 210 is fixedly installed on the top of the second sealing plate 29. A support-type mesh plate 211 is fixedly installed on the top of the support frame 210. As the support-type threaded rod 21 is rotated, causing the threaded sleeve 27 to move upward on its outer wall, the angle at the intersection of the first support 25 and the second support 26 gradually decreases. The limiting slide groove 213 slides towards the support-type threaded rod 21 in the inner cavity of the slider 214. Simultaneously, the first sealing plate 28... The first sealing plate 28 and the second sealing plate 29 gradually move towards the bottom of the inner sintering shell 101 until the supporting mesh plate 211 extends into the inner cavity of the inner sintering shell 101. The first sealing plate 28 and the second sealing plate 29 seal the bottom of the inner sintering shell 101, so that the material placed on top of the supporting mesh plate 211 can be sintered. After sintering, by driving the supporting threaded rod 21 to reverse, the first sealing plate 28 and the second sealing plate 29 together move the supporting mesh plate 211 and the material downward, so that the material can be smoothly removed from the inside of the inner sintering shell 101. This avoids the problem of the material being difficult to handle due to its high temperature and the risk of burns when the material needs to be removed manually in the traditional way.
[0043] The top of the sintering furnace mechanism 1 is connected to a ventilation mechanism 3, and the outer wall of the ventilation mechanism 3 is connected to a heat recovery mechanism 4.
[0044] The inner sintering shell 101 has an open top and bottom, and multiple microwave generators 103 are arranged in a ring-shaped, equidistant manner on the inner wall of the inner sintering shell 101. This arrangement aims to ensure uniform heating from multiple directions within the inner sintering shell 101 by the multiple microwave generators 103, resulting in uniform heating during material sintering. Further, referring to… Figure 4 As shown, a limiting groove 215 is provided on the top of the first base 22, and a connecting type rotating seat 216 that is fixedly connected to the limiting sleeve 24 is rotatably installed on the top of the first support 25. The purpose of this arrangement is to prevent the limiting sleeve 24 from rotating synchronously when the supporting threaded rod 21 rotates. Meanwhile, referring to... Figure 3-4 As shown, multiple support-type threaded rods 21 are arranged in a ring at equal intervals around the bottom of the outer insulation shell 102, combined with... Figure 7 As shown, multiple supporting threaded rods 21 are arranged in a one-to-one correspondence with the balancing lifting blocks 212. This arrangement aims to ensure that the multiple first supports 25, in conjunction with the balancing lifting blocks 212, can simultaneously and smoothly lift the bottom of the first sealing plate 28, thereby maintaining the stability of the first sealing plate 28 and the second sealing plate 29 as a whole during vertical movement. Further, refer to... Figure 4As shown, the outer circumferential diameter of the second sealing plate 29 is less than the diameter of the bottom opening of the inner sintered shell 101, and the length between the outer circumferences of the first sealing plate 28 is greater than the length between the circumferences at the bottom opening of the inner sintered shell 101. The purpose of this arrangement is that after the first sealing plate 28, the second sealing plate 29, and the supporting mesh plate 211 are lifted upwards into the inner cavity of the inner sintered shell 101, the second sealing plate 29 can initially seal the opening of the inner sintered shell 101, and the first sealing plate 28 can then seal the bottom opening of the inner sintered shell 101 again, thus sealing the bottom opening of the inner sintered shell 101.
[0045] As a further expansion of this plan, refer to Figure 5 As shown, the ventilation mechanism 3 includes a first gas chamber 31 connected to the top opening of the inner sintered shell 101. The first gas chamber 31 has multiple through-type gas outlet slots 32. A connecting threaded rod 33 is rotatably mounted inside the first gas chamber 31. A third sealing plate 36 engages with the outer wall of the connecting threaded rod 33. Under normal conditions, the third sealing plate 36 moves and stops at the top of the first gas chamber 31, thus connecting the inner sintered shell 101, the first gas chamber 31, and the gas outlet slots 32. The purpose of this arrangement is to allow the third sealing plate 36 to move up and down along the outer wall of the rotating connecting threaded rod 33. When the third sealing plate 36 moves to the bottom of the vent groove 32, it can block the connection between the inner sintered shell 101 and the first gas chamber 31. When the third sealing plate 36 moves to the top of the vent groove 32, it can connect the inner sintered shell 101 and the inner cavity of the first gas chamber 31, allowing the hot air inside the inner sintered shell 101 to be discharged through the vent groove 32. Simultaneously, combined with... Figure 8 As shown, a support block 34 is rotatably mounted on the bottom of the connecting threaded rod 33. Multiple support frames 35, which are fixedly connected to the annular support plate 104, are fixedly mounted on the outer wall of the support block 34. A hydraulic telescopic rod 37, which is fixedly connected to the third sealing plate 36, is fixedly mounted on the top of the annular support plate 104. The purpose of this arrangement is to ensure that when the connecting threaded rod 33 is rotated, the third sealing plate 36 can be supported by the hydraulic telescopic rod 37 and move smoothly upward on its outer wall. Furthermore, the arrangement of the support block 34 and the support frames 35 makes the rotation of the connecting threaded rod 33 more stable.
[0046] Combination Figure 5 and Figure 10As shown, a support-type rotating shaft 52 is rotatably installed inside the support sleeve 51. A stepper motor for driving the support-type rotating shaft 52 to rotate is fixedly installed inside the support sleeve 51. A first gear 53 is fixedly connected to the top of the support-type rotating shaft 52. A second gear 54 is fixedly connected to one end of the connecting threaded rod 33 extending out of the top of the first air chamber 31. The outer walls of the first gear 53 and the second gear 54 are meshed with a first synchronous belt 55. The purpose of this arrangement is to enable the first gear 53 and the second gear 54 to rotate synchronously when the support-type rotating shaft 52 is rotated, thereby causing the connecting threaded rod 33 to rotate inside the first air chamber 31 and adjust the position of the third sealing plate 36.
[0047] Synchronous, combined Figure 3 As shown, a third gear 56 is fixedly connected to one end of the supporting shaft 52 that passes through the first base 22, in conjunction with... Figure 9-10 As shown, multiple support-type threaded rods 21 penetrate the bottom of the first base 22, and the bottom of each support-type threaded rod 21 is fixedly connected to a fourth gear 57. The outer walls of the third gear 56 and the fourth gear 57 are meshed with a second synchronous belt 58. This arrangement is intended to ensure that when the support-type rotating shaft 52 synchronously drives the third gear 56 to rotate, the second synchronous belt 58 synchronously drives the fourth gear 57 to rotate, thereby causing the corresponding support-type threaded rods 21 to rotate, thus synchronously driving the first sealing plate 28 and the fourth gear 57. The second sealing plate 29 and the supporting mesh plate 211 together drive the material to move up and down. At the same time, the outer walls of multiple supporting threaded rods 21 are also fixedly installed with fifth gears 59. The outer walls of the fifth gears 59 set on the outer walls of every two adjacent supporting threaded rods 21 are meshed with third synchronous belts 510. The purpose of this arrangement is to enable every two adjacent supporting threaded rods 21 to rotate synchronously, thereby enabling the first sealing plate 28, the second sealing plate 29 and the supporting mesh plate 211 to move up and down smoothly as a whole.
[0048] As a further expansion of this plan, refer to Figure 7-8As shown, the heat recovery mechanism 4 includes a second air chamber 41 fixedly installed on the outer wall of the first air chamber 31. The second air chamber 41 is interconnected with the inner cavity of the first air chamber 31 through an air outlet groove 32. Multiple air vents 42 are connected to the outer wall of the second air chamber 41, and one end of each air vent 42 is connected to a third air chamber 43. The third air chambers 43 are fixedly installed inside the inner sintered shell 101 and the outer insulation shell 102. Each third air chamber 43 extending into the inner cavity of the inner sintered shell 101 is connected to a diffuser chamber 44. A valve controller 45 for controlling the ventilation of the diffuser chamber 44 is fixedly installed at the connection between the third air chamber 43 and the diffuser chamber 44. A valve is provided at the connection between the third air chamber 43 and the diffuser chamber 44, and the valve controller 45 is used to open and close the valve. The purpose of this arrangement is... The purpose is to ensure that when the first sealing plate 28 and the second sealing plate 29 move downward as a whole, the third sealing plate 36 moves upward on the outer wall of the connecting threaded rod 33 and exposes the air groove 32 first, so that the inner sintering shell 101 is connected to the first air chamber 31 and the second air chamber 41. This allows the hot air inside the inner cavity of the inner sintering shell 101 to flow into the inner cavity of the third air chamber 43 through the vent pipe 42 and be stored. This is so that when the material is sintered continuously in the future, the valve controller 45 can be opened simultaneously so that the hot air inside the third air chamber 43 can enter the inner cavity of the inner sintering shell 101 through the air diffuser 44 to preheat the inner cavity of the inner sintering shell 101. This avoids the problem that the microwave generator 103 has a slow temperature rise process in actual use, which would lead to a long time consumption and affect the work efficiency when sintering different materials continuously.
[0049] A method for using a continuous hard carbon anode material sintering furnace, the specific steps of which are as follows:
[0050] First, the material to be sintered is placed on the support mesh plate 211. Then, the stepper motor inside the support sleeve 51 is driven to rotate, so that the support shaft 52 rotates synchronously. This causes the first gear 53 to drive the second gear 54 through the first synchronous belt 55, which in turn causes the connecting threaded rod 33 to rotate. Simultaneously, the support shaft 52 drives the third gear 56 to rotate, which in turn drives multiple support threaded rods 21 to rotate. This allows the third sealing plate 36 to move down on the outer wall of the connecting threaded rod 33 and gradually move towards the support block 34 to block the connection between the inner sintering shell 101 and the microwave generator 103.
[0051] The second step involves the rotating support-type threaded rod 21 causing multiple corresponding and intersecting first supports 25 and second supports 26 to deflect, thereby causing the height of the first sealing plate 28 and the second sealing plate 29 to move steadily upward until the support-type mesh plate 211 extends the material into the interior of the inner sintering shell 101, and the first sealing plate 28 and the second sealing plate 29 double-seal the bottom of the inner sintering shell 101. Then, the microwave generator 103 can be started to perform sintering treatment in the inner cavity of the inner sintering shell 101.
[0052] Third step: After sintering is completed, the stepper motor inside the synchronous drive support sleeve 51 is reversed, which causes the connecting threaded rod 33 and the supporting threaded rod 21 to reverse synchronously, thereby causing the third sealing plate 36 to move up gradually and the supporting mesh plate 211 to move down gradually. When the third sealing plate 36 moves to the air outlet groove 32, the hot air in the inner cavity of the inner sintered shell 101 can be discharged first.
[0053] Fourth step: The hot air discharged through the air outlet 32 is stored in the inner cavity of the third air chamber 43 through the air pipe 42.
