[0002] The horizontal furnace's graphite heating element has a unique structure that cleverly combines efficient heating with stable operation. The graphite heating element is evenly distributed throughout the furnace, ensuring uniform heat transfer and efficient utilization.

[0003] A search of the prior art revealed a Chinese patent application for a "horizontal pressure sintering furnace," with application number "202223580931.2." This patent primarily comprises a support base and a furnace body, with furnace doors on either side. The support base is fixed to the ground, and the furnace body is mounted on top of the support base. An air inlet is provided at the top of the furnace body, and an air outlet is provided at the bottom of the furnace body. Graphite support columns are fixed to the bottom of the furnace body, and a graphite base plate is mounted on top of the graphite support columns. Two rows of parallel support rollers are mounted on the top plane of the graphite base plate. A muffle housing is located between the two rows of parallel support rollers. A pin mechanism and a power mechanism are mounted on either side of the muffle housing. A groove die is provided on the side wall of the muffle housing near the power mechanism. Multiple rod-shaped graphite heating elements are arranged around the muffle housing, and graphite electrodes are mounted on the graphite heating elements. While this utility model sinters the material through the rotation of the muffle, it utilizes changes in furnace pressure to control the flow of the reaction gas.

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Reference Figure 1-4 The horizontal furnace graphite heating body structure of the utility model embodiment includes a furnace body 1, a plurality of graphite heating bodies 7 evenly arranged on the inner wall of the furnace body 1, a furnace door 2 arranged at the opening of the furnace body 1, a muffle shell 5 arranged inside the furnace body 1 and a muffle shell cover 6 arranged at the opening of the muffle shell 5. The side of the furnace door 2 close to the muffle shell 5 is fixedly connected to a connecting plate 17 through a plurality of evenly arranged fixing rods 16. The interior of the furnace door 2 is slidably connected to a movable shaft 3. The side of the movable shaft 3 close to the connecting plate 17 is provided with an external thread. The movable shaft 3 is threadedly connected to the connecting plate 17 through the external thread. The end of the movable shaft 3 close to the external thread is rotatably connected to the muffle shell cover 6, and the end of the movable shaft 3 located outside the furnace body 1 is fixedly connected to a turntable 4.

[0023] After loading is completed inside the muffle shell 5, the furnace door 2 is rotated and closed to achieve a sealed effect on the furnace body 1. The operating turntable 4 drives the movable shaft 3 to rotate. The rotating movable shaft 3 can achieve horizontal movement operation through a threaded connection with the connecting plate 17. The moving movable shaft 3 drives the muffle shell cover 6 to cover the opening of the muffle shell cover 6, completing the sealing operation of the muffle shell 5. The operation is simple. When it is necessary to remove materials, the turntable 4 is rotated in the opposite direction to rotate the movable shaft 3, thereby separating the muffle shell cover 6 from the muffle shell 5. At this time, the furnace door 2 can be opened together with the muffle shell cover 6 to complete the opening operation, facilitating the removal of materials. The door and cover linkage design simplifies the opening and closing process, making the loading and removal process faster and smoother, and helping to improve work efficiency. Secondly, it avoids potential risks caused by improper opening and closing of the muffle shell cover 6, enhancing operational safety.

[0024] In order to realize the rotation of the muffle shell 5, a rotating shaft 13 is rotatably connected to the side inside the furnace body 1 opposite to the opening, and the end of the muffle shell 5 close to the rotating shaft 13 is fixedly connected to the rotating shaft 13. A driving assembly for driving the rotating shaft 13 to rotate is provided on the side outside the furnace body 1 close to the rotating shaft 13. The driving assembly includes a motor 15 and two pulleys 14 installed on the outside of the furnace body 1. The two pulleys 14 are respectively fixedly connected to the output shaft of the motor 15 and one end of the rotating shaft 13.

[0025] The operation of the motor 15 drives the pulley 14 to rotate, thereby driving the rotation of the rotating shaft 13 and the muffle shell 5 , thereby achieving rotational heating of the muffle shell 5 .

[0026] In order to support the rotation of the muffle shell 5, a rolling assembly is symmetrically provided inside the furnace body 1 and below the muffle shell 5. The rolling assembly includes a plurality of support plates 8 evenly fixedly connected to the inner surface of the furnace body 1, a mounting plate 9 fixedly connected to the top of the plurality of support plates 8, four fixed plates 10 fixedly connected to the top of the mounting plate 9 and two rollers 11. The two rollers 11 are respectively installed between every two adjacent fixed plates 10. The middle part of the rollers 11 is provided with a groove structure. A circular protrusion 12 is fixedly connected to the outer side of the muffle shell 5, and the circular protrusion 12 is rollingly connected with the groove structure.

[0027] The roller 11 can better support the muffle shell 5 while ensuring the free rotation of the muffle shell 5. The rolling connection between the annular protrusion 12 and the groove structure of the roller 11 can ensure the stability and smoothness of the muffle shell 5 during rotation.

[0028] The trapezoidal cross-section of the muffle cover 6 increases the contact surface between the muffle cover 6 and the opening of the muffle housing 5, thereby providing a better seal at the connection. The furnace body 1 is configured as a cone, and a suitable distance is provided between the opening of the muffle housing 5 and the opening of the furnace body 1. This design ensures that when the muffle cover 6 is separated from the muffle housing 5, there is sufficient distance between the two to ensure that the muffle cover 6 can rotate with the furnace door 2.

[0029] Working Principle: After loading is completed within the muffle shell 5, the furnace door 2 rotates and closes to seal the furnace body 1. The operating dial 4 drives the movable shaft 3 to rotate. The rotating movable shaft 3 is threadedly connected to the connecting plate 17 to achieve horizontal movement. The moving movable shaft 3 drives the muffle shell cover 6 to close over the opening of the muffle shell cover 6, completing the sealing operation of the muffle shell 5. The operation is simple. When it is necessary to remove the material, the turntable 4 is rotated in the opposite direction to rotate the movable shaft 3, thereby separating the muffle shell cover 6 from the muffle shell 5. At this time, the furnace door 2 and the muffle shell cover 6 can be opened together to complete the opening operation, facilitating the removal of the material. The door and cover linkage design simplifies the opening and closing process, making the loading and removal process faster and smoother, thereby improving work efficiency. Secondly, it avoids potential risks caused by improper opening and closing of the muffle shell cover 6, enhancing operational safety.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
