Description

Technical Field

[0001] This utility model belongs to the field of graphite ball processing technology, and in particular relates to a heating device for carbonization treatment of graphite ball surface. Background Technology

[0002] Graphite ball surface carbonization technology is widely used in metallurgy, machinery manufacturing, new energy and other fields. Its core purpose is to improve the hardness, wear resistance and high temperature resistance of graphite balls through carbonization treatment to meet the needs of different application scenarios.

[0003] CN207551919U discloses a graphite heating device, including a housing, a top cover, an electrical control box, a discharge plate, a heating plate, a bottom groove, a rotating shaft, fan blades, a blower, a collection port, a bottom opening, and support legs. The beneficial effects of this invention are: by installing a collection port inside the bottom of the housing, graphite can be discharged quickly, which is beneficial for the cooling of the graphite after heating. To facilitate the use of the heated graphite and to facilitate collection during cooling, the housing is designed with a dense mesh of round holes, and the heating plate has holes to increase heat dissipation. The support legs installed below the housing ensure convenient graphite discharge. The heating plate installed inside the housing facilitates heating, and the fan blades installed below the heating plate, with a rotating shaft installed below the fan blades, accelerates heat dissipation. The structure is compactly connected, and the electrical control box facilitates the control of the heating plate, making operation simple.

[0004] The proposed solution uses heating plates installed inside the chamber for heating. This method has the following problems: First, relying solely on heating plates makes it difficult to achieve multi-directional and multi-layer heating, which can easily lead to uneven carbonization on the surface of the graphite spheres. Second, the loading and unloading process of this device may require manual handling of the storage containers, which not only increases the labor intensity of operators but also poses safety hazards. Furthermore, the loading and unloading time is relatively long, which is not conducive to industrial-scale mass production.

[0005] To address these issues, we have provided a heating device for carbonizing the surface of graphite spheres. Utility Model Content

Through the cooperation of a high-efficiency heating mechanism, a driving mechanism, and a storage mechanism, it solves the problems of poor heating effect, low heating efficiency, and inconvenient loading and unloading in the existing heating devices.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

The efficient heating mechanism includes an induction heating coil fixed to the inner wall of the housing. A microwave heater and an ultrasonic transducer are sequentially fixedly connected to one side of the housing from front to back, with the working parts of both the microwave heater and the ultrasonic transducer penetrating into the housing cavity.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0026] Please see Figure 1-5 This utility model is a heating device for carbonization treatment of graphite spheres, including a housing 1. A high-efficiency heating mechanism 2 is provided in the inner cavity of the housing 1. A driving mechanism 3 is provided at the top of the inner cavity of the housing 1, and a storage mechanism 4 is provided at the bottom of the driving mechanism 3. The high-efficiency heating mechanism 2 includes an induction heating coil 21, which is fixed to the inner wall of the housing 1. A microwave heater 22 and an ultrasonic transducer 23 are fixedly connected to one side of the housing 1 from front to back. The working parts of the microwave heater 22 and the ultrasonic transducer 23 both penetrate into the inner cavity of the housing 1. The driving mechanism 3 includes a housing 31, which is fixed to the top of the inner cavity of the housing 1. A threaded rod 32 is movably connected to the inner wall of the housing 31 through a bearing. A first motor 33 is fixedly connected to one side of the housing 1. The output end of the first motor 33 is fixedly connected to one end of the threaded rod 32. A movable sleeve 34 is threadedly connected to the surface of the threaded rod 32. A fixed plate 35 is fixedly connected to the bottom of the movable sleeve 34.

[0027] Specifically, the high-efficiency heating mechanism 2 innovatively combines an induction heating coil 21, a microwave heater 22, and an ultrasonic transducer 23: the induction heating coil 21 provides basic electromagnetic heating, the microwave heater 22 achieves precise heating deep into the surface, and the ultrasonic transducer 23 improves the uniformity of heating through vibration. The three work together to form a multi-directional and multi-layer heating system. Compared with the existing single heating method, the heating uniformity is improved, the carbonization qualification rate is increased, and the problem of uneven carbonization on the surface of graphite balls is solved. Secondly, the drive mechanism 3 realizes the automated entry and exit of the storage mechanism 4 into and out of the box 1, eliminating the need for manual handling of the storage container, shortening the loading and unloading time, reducing the labor intensity of operators, avoiding the safety hazards of manual handling, and greatly improving the working efficiency of the equipment, perfectly adapting to the needs of industrial mass production. Example 2

[0028] Please see Figure 1-5Based on Embodiment 1, a sliding rod is provided through the surface of the movable sleeve 34, and the surface of the sliding rod is slidably connected to the movable sleeve 34. Both ends of the sliding rod are fixedly connected to the inner wall of the housing 31. The storage mechanism 4 includes a storage mesh box 41, which is fixed to the bottom of the fixed plate 35. A sealing plate 42 is fixedly connected to one side of the storage mesh box 41. A rotating rod 43 is movably connected to the inner wall of the storage mesh box 41 through a bearing. Evenly distributed stirring blades 44 are fixedly connected to the surface of the rotating rod 43. The side of the sealing plate 42 away from the storage mesh box 41 is fixed. A second motor 45 is connected, and the output end of the second motor 45 is fixedly connected to one end of the rotating rod 43. A sealing gasket is provided at the connection between the box body 1 and the sealing plate 42. One side of the sealing gasket is fixedly connected to the box body 1. A door is movably connected to one side of the surface of the storage net box 41 through a hinge. A lock cylinder is provided through the surface of the door. A receiving groove is opened on one side of the top front of the box body 1. A nameplate is fixedly connected to the inner wall of the receiving groove. A cabinet body 5 is fixedly connected to the bottom of the box body 1. A cabinet door is movably connected to the surface of the cabinet body 5 through a hinge. A handle is fixedly connected to the front of the cabinet door.

[0029] Specifically: The sliding rod effectively restricts the rotational freedom of the moving sleeve 34, allowing it to move smoothly only along the horizontal direction of the sliding rod. This ensures the positional accuracy of the storage mechanism 4 when entering and exiting the housing 1, preventing graphite balls from spilling or equipment parts from being damaged due to shaking. This further improves the reliability of the drive mechanism 3 and the overall safety of the equipment. The storage mesh box 41 adopts a mesh structure, which, compared to existing sealed storage containers, allows the microwave, ultrasonic, and inductive heat from the high-efficiency heating mechanism 2 to penetrate more fully to the surface of the graphite balls, preventing heat accumulation in the container and causing local overheating, thus further improving heating uniformity. The second motor 45 drives the rotating rod 43 and the stirring blade 44 to rotate, continuously turning the graphite balls in the storage mesh box 41 to ensure that each graphite ball is evenly heated. The uniform contact with the heat source solves the problem of "uneven local carbonization" caused by existing static storage. At the same time, the turning process can accelerate the heat exchange on the surface of the graphite balls. The sealing gasket ensures the airtightness of the cabinet 1, which reduces energy consumption and ensures the stability of the carbonization effect. The nameplate can mark key information such as equipment model, parameters, operating instructions, and maintenance cycle. When using or maintaining the equipment, operators can quickly obtain the required information without consulting additional manuals, reducing the difficulty of operation. Cabinet 5 provides additional storage space and protection functions. Cabinet 5 can be used to store tools for loading and unloading graphite balls, equipment maintenance parts, operating manuals, and other items, preventing these items from being lost or damaged due to random placement, improving the cleanliness of the work site and the convenience of item management.

[0030] The working principle of this utility model is as follows: First, the first motor 33 in the drive mechanism 3 is started. The output end of the first motor 33 drives the threaded rod 32 connected to the inner wall of the housing 31 through the bearing to rotate. Since the movable sleeve 34 is threadedly connected to the threaded rod 32 and the movable sleeve 34 is sleeved on the slide rod fixed at both ends to the inner wall of the housing 31, the rotation of the threaded rod 32 will drive the movable sleeve 34 to move horizontally along the slide rod, thereby driving the storage mechanism 4 connected to the bottom fixing plate 35 of the movable sleeve 34 to extend out of the box 1. Then, the box door connected to the surface of the storage mesh box 41 through the hinge is opened, and the graphite balls to be carbonized are placed into the storage mesh box 41. The box door is closed and locked to complete the loading. The first motor 33 is started again to drive the threaded rod 32 to rotate in the opposite direction, so that the movable sleeve 34 drives the storage mesh box 41 to re-enter the inner cavity of the box 1 until the sealing plate 42 on one side of the storage mesh box 41 is in contact with the box 1. Then, the induction heating coil 21, microwave heater 22 and ultrasonic transducer 23 of the high-efficiency heating mechanism 2 are started at the same time. The induction heating coil 21 is fixed to the inner wall of the box 1 and provides basic heating to the graphite balls in the storage cage 41 through electromagnetic induction. The working part of the microwave heater 22 extends into the interior of the box 1 and uses microwave radiation to precisely heat the surface of the graphite balls. The ultrasonic transducer 23 uses ultrasonic vibration to make the surface of the graphite balls heat more evenly, avoiding local overheating or underheating. At the same time, the second motor 45 on one side of the sealing plate 42 in the storage mechanism 4 is started. The second motor 45 drives the rotating rod 43 connected to the inner wall of the storage cage 41 through the bearing to rotate. The stirring blade 44 on the surface of the rotating rod 43 rotates accordingly, continuously turning the graphite balls, further ensuring that the surface of each graphite ball can be evenly contacted with the heat source, improving the carbonization effect. After the carbonization process reaches the preset time, all components of the high-efficiency heating mechanism 2 and the second motor 45 are turned off, and the first motor 33 is started again to drive the storage cage 41 to extend out of the box 1. The box door is opened, and the carbonized graphite balls are taken out, completing the entire carbonization process.
