[0002] Graphite horizontal heating furnaces are widely used in the heating process of high-temperature furnace bodies. Their structural design has high requirements for sealing and ease of operation. Since the heating furnace works in a high-temperature environment, the sealing of the furnace cover directly affects the heating efficiency, energy consumption and safety of the furnace body.
[0003] However, during long-term use, it was found that the traditional furnace cover sealing structure still has some shortcomings. Specifically, when the sealing rubber ring has been in effect during the continuous tightening process, the existing locking assembly lacks certain feedback and often continues to tighten. This over-locking situation will cause damage to the sealing rubber ring after repeated occurrences, affecting the sealing effect and increasing maintenance costs.
[0004] In order to solve these problems, practitioners have designed a furnace cover sealing structure for a graphite horizontal heating furnace. Utility Model Content
[0005] The purpose of this utility model is to provide a furnace cover sealing structure for a graphite horizontal heating furnace in order to solve the problem that the existing horizontal heating furnace sealing structure lacks certain feedback during the sealing and locking process, which easily causes excessive locking and damages the internal sealing rubber ring.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0026] Example 1:
[0027] Combine Figure 1-5 The furnace cover sealing structure shown in the figure is used for a graphite horizontal heating furnace, which is designed to ensure the sealing performance of the horizontal heating furnace, prevent leakage in a vacuum environment, and realize an intuitive feedback sealing and locking process. The sealing structure includes several key components. The first is a heating furnace body 1. A sealing bottom member 2 is provided at one end of the heating furnace body 1. A furnace cover assembly 4 is provided at one end of the sealing member 2 through a rotating member 3. The rotating member 3 allows the furnace cover assembly 4 to be easily opened and closed, thereby facilitating operation and maintenance of the interior of the heating furnace body 1. The sealing member 2 and the furnace cover assembly 4 form a tight fit through the locking assembly 5, ensuring that the furnace cover assembly 4 is stably fixed during use and will not loosen due to vacuum environment pressure or working vibration, thereby avoiding leakage or other potential problems.
[0028] The furnace cover assembly 4 includes a furnace cover body 401, and a kit 402 is slidably provided on the furnace cover body 401. This arrangement ensures that the kit 402 can show a certain intuitive displacement state during the sealing and locking process. A spring 403 is provided between the furnace cover body 401 and the kit 402. The function of the spring 403 is to provide appropriate elastic force to ensure the reset of the kit 402 before the secondary seal. The furnace cover body 401 is evenly distributed with several groups of anti-slip bolts 404 along the circumferential direction. The side wall of the kit 402 is provided with a guide groove 405 that cooperates with the anti-slip bolt 404. This part of the design utilizes that as the sealing and locking process proceeds, the kit 402 will The cover body 401 is pushed forward, and the guide groove 405 on its surface will change its end position on the anti-slip bolt 404 during the pushing process. When the end position changes, it indicates that the sealing rubber ring 406 has performed the sealing effect. At this time, it can be slightly tightened to avoid excessive tightening and damage to the sealing rubber ring 406. A sealing rubber ring 406 is provided at the end of the guide groove 405. The function of the sealing rubber ring 406 is to fill the tiny gap between the furnace cover assembly 4 and the sealing bottom part 2 to ensure that the leakage of hot air or gas in the internal vacuum environment can be prevented even in a high temperature environment. Its material and design ensure the reliability of the seal, thereby extending the service life of the furnace cover sealing structure.
[0029] In this embodiment, the Figure 3 One end of the sealing base member 2 shown is provided with a beading groove 201 that cooperates with the sealing rubber ring 406. The size and shape of the beading groove 201 are precisely designed to ensure that the sealing rubber ring 406 can be firmly embedded therein, thereby forming an effective sealing structure. The embedding of the sealing rubber ring 406 in the beading groove 201 prevents gas leakage and ensures the sealing and stability of the entire system. In addition, this design can effectively reduce the risk of sealing failure caused by vibration or internal pressure changes, thereby improving the service life and reliability of the equipment.
[0030] In this embodiment, the Figure 2 The rotating part 3 shown includes a rotating bottom part 301 arranged on the side wall of the sealing bottom part 2, which serves as part of the rotating system to support the opening and closing operations of the furnace cover assembly 4, and an external retaining part 302 arranged on the side wall of the furnace cover main body 401, which has a structure matching the rotating bottom part 301. The rotating bottom part 301 and the external retaining part 302 are matched through the rotating shaft 303. The rotating shaft 303 serves as the core connecting part of the rotating part 3, connecting the rotating bottom part 301 and the external retaining part 302, so that the furnace cover main body 401 can rotate around the rotating shaft 303. The design of the rotating shaft 303 not only ensures that the furnace cover assembly 4 can be opened and closed smoothly, but also can withstand the gravity from the furnace cover part.
[0031] In this embodiment, the outer wall of the furnace cover body 401 fits tightly with the inner wall of the kit 402. This design ensures a stable combination between the two and has good sealing performance. Specifically, the outer wall of the furnace cover body 401 is precisely processed, the surface is smooth and the size is strictly controlled to ensure the matching accuracy with the inner wall of the kit 402. During assembly, the contact surface between the furnace cover body 401 and the kit 402 is completely fitted, effectively preventing gas leakage.
[0032] In this embodiment, the Figure 5 The locking assembly 5 shown is designed to ensure a tight fit between the sealing bottom piece 2 and the furnace cover assembly 4, and to prevent the furnace cover assembly 4 from loosening or shifting during use. The locking assembly 5 includes a plurality of precision components, including a locking bottom piece 501 fixedly arranged on the side wall of the sealing bottom piece 2. The function of the locking bottom piece 501 is to provide stable support and positioning for the entire locking system, ensuring that other components can accurately cooperate with it. A threaded rod 502 is rotatably provided in the cavity of the locking bottom piece 501. By rotating the threaded rod 502, interference when opening the furnace cover assembly 4 can be avoided. A threaded rod 502 is sleeved on the threaded rod 502 to engage with the locking bottom piece. Part 501 cooperates with locking part 503, and locking part 503 is used to further increase the cooperation with locking base part 501 and ensure that during the locking operation, locking part 503 can be firmly stuck in the fixed position to prevent loosening. A clamp 504 cooperating with threaded rod 502 is provided on one side of the locking part 503. The clamp 504 is used to stabilize the position of the locking part 503. A rocker arm 505 is provided on the clamp 504. The design of the rocker arm 505 allows the operator to easily adjust the rotation of the clamp 504 by shaking or twisting the rocker arm 505, thereby realizing simple and efficient locking and unlocking operations.
