[0031] Reference Figure 1~Figure 3, which is the first embodiment of the utility model, proposes an explosion-proof furnace with a sealing structure, comprising: a furnace body 1, wherein the furnace body 1 has a accommodating space 2; an upper cover 3 is detachably arranged on the furnace body 1; a first guide block 4 is arranged on the furnace body 1; a second guide block 5 is arranged on the upper cover 3, and the first guide block 4 and the second guide block 5 have a guide slope 6 on one side close to each other; a fastening sleeve 7 has a fastening space 8, and the fastening sleeve 7 is detachably arranged on the furnace body 1, and the second guide block 5 is located in the fastening space 8. After the upper cover 3 is installed, the first guide block 4 is located in the fastening space 8. After the upper cover 3 is rotated, the two guide slopes 6 abut against each other, and the first guide block 4 and the second guide block 5 abut against the inner wall of the fastening space 8. There are a plurality of first sealing blocks 9, which are arranged on the furnace body 1. The first sealing block 9 has a sealing slope 10 on the side close to the upper cover 3. There are a plurality of second sealing blocks 11, which are arranged on the upper cover 3. The second sealing block 11 has a matching slope 12 on the side close to the furnace body 1. After the upper cover 3 is installed on the furnace body 1, the matching slope 12 is sealed and matched with the sealing slope 10.

[0032] In this embodiment, the storage space 2 of the furnace body 1 is used to carry the material and the impact force after the material explodes. The furnace body 1 is made of high-temperature resistant and high-strength alloy material, and a spacious storage space 2 is designed inside. The storage space 2 is intended to load materials that need to be heated, and its size is customized according to specific application requirements to ensure sufficient operating capacity while maintaining the compactness of the structure. The upper cover 3 is made of a heat-resistant material that matches the furnace body 1, and a tight and detachable connection with the furnace body 1 is achieved through a precise mechanical interface design. This design is convenient for daily inspection and maintenance, and also ensures good sealing. The furnace body 1 is fixedly mounted with a first guide block 4, and the upper cover 3 is provided with a second guide block 5. The two sets of guide blocks are respectively located on both sides of the fastening sleeve 7, and the sides close to each other are processed with precise guide bevels 6. When the upper cover 3 approaches the furnace body 1 and rotates into place, the guide bevels 6 are precisely docked, which not only guides the upper cover 3 to close correctly, but also ensures smooth movement between the upper cover 3 and the furnace body 1, reducing wear. The fastening sleeve 7 is a key component, and its fastening space 8 is specially designed for the first guide block 4 and the second guide block 5. The fastening sleeve 7 can be fixed on the furnace body 1 by threads, buckles or other reliable locking mechanisms to ensure that the upper cover 3 is stable and does not shift after installation, and at the same time provide support for the sealing structure. The first sealing blocks 9 are evenly distributed around the furnace body 1, and each block has a sealing bevel 10 with a specific angle. Correspondingly, a second sealing block 11 is installed on the inner side of the upper cover 3, and the matching bevel 12 thereon is designed to match the sealing bevel 10. When the upper cover 3 is fully closed and pressed by the force of the fastening sleeve 7, the sealing bevel 10 fits tightly with the matching bevel 12 to form a reliable airtight seal, which effectively prevents dangerous gases in the external environment from entering the furnace, and also prevents the explosion gas that may be generated in the furnace from leaking out. The explosion-proof furnace with a sealing structure in this embodiment not only ensures safety during use through a sophisticated guiding and sealing design, but also improves the reliability and maintainability of the equipment, and is suitable for a variety of industrial heating scenarios with potential explosion risks.

[0033] As a further technical solution, the fastening sleeve 7 is provided with a plurality of avoidance grooves 13 , and the first guide block 4 enters the fastening space 8 from the avoidance grooves 13 .

[0034] In this embodiment, the design details of the fastening sleeve 7 are refined to enhance its operational convenience and sealing performance. Specifically, the fastening sleeve 7 not only has a fastening space 8 for accommodating the second guide block 5 and finally cooperating with the first guide block 4, but also cleverly designs a number of avoidance grooves 13 in its structure. The positions and sizes of these avoidance grooves 13 are carefully calculated to ensure that when the upper cover 3 is installed on the furnace body 1, the first guide block 4 can smoothly slide from the avoidance groove 13 into the fastening space 8. This design avoids the need for direct alignment and forced pushing, reduces resistance during assembly, makes operation easier and faster, and also protects the guide block and the fastening sleeve 7 from unnecessary wear. The presence of the avoidance groove 13 also creates conditions for the formation of a sealing structure. When the upper cover 3 is fully in place and rotated, the first guide block 4 and the second guide block 5 are tightly fitted through their respective guide bevels 6, and the sides of the two will also form a stable support with the inner wall of the fastening space 8, further enhancing the sealing and stability of the entire furnace body 1, effectively preventing possible gas leakage in a high temperature and high pressure environment, and ensuring the safe operation of the explosion-proof furnace.

[0035] As a further technical solution, it also includes: a first sealing seat 14 is arranged on the furnace body 1, and a second sealing seat 15 is arranged on the upper cover 3. After the upper cover 3 is installed on the furnace body 1, a clamping space 16 is formed between the first sealing seat 14 and the second sealing seat 15, and the fastening sleeve 7 is located in the clamping space 16; a first sealing gasket 17 is arranged on the first sealing seat 14 and the second sealing seat 15, and the first sealing gasket 17 is used to seal the gap between the fastening sleeve 7 and the first sealing seat 14 and the second sealing seat 15.

[0036] In this embodiment, the first sealing seat 14 is installed at an appropriate position of the furnace body 1, aiming to provide a stable foundation for the connection of the upper and lower components and participate in forming a sealing interface. The second sealing seat 15 is arranged at the corresponding position of the upper cover 3. When the upper cover 3 is installed on the furnace body 1, the first sealing seat 14 and the second sealing seat 15 are precisely aligned and close to each other. The clamping space 16 formed between the two provides a holding position for the fastening sleeve 7, which is also a key area for sealing. The fastening sleeve 7 is placed inside this clamping space 16, and the guide block structure mentioned above ensures that the upper and lower components are correctly aligned and firmly connected. It is placed between the first sealing seat 14 and the second sealing seat 15, playing a vital sealing role. The sealing gasket uses its own elastic or plastic deformation to fill the small gap between the fastening sleeve 7 and the two sealing seats, thereby forming a reliable sealing barrier, effectively preventing the penetration of internal and external gases, and ensuring that the furnace body 1 still maintains good airtightness under high temperature, high pressure or specific working environment, and meets the explosion-proof safety standard. This sealing structure design not only improves the safety level of the explosion-proof furnace, but also optimizes the durability and maintenance convenience of the equipment. It is an important innovation in the design of explosion-proof equipment.

[0037] As a further technical solution, the first sealing pad 17 is an inflatable pad.

[0038] In this embodiment, the inflatable pad can be used as a further technical solution. The top of the furnace body 1 and the bottom of the upper cover 3 both have chamfers 18, and the two chamfers 18 are sealed and matched.

[0039] In this embodiment, the two chamfers 18 fit tightly together, so that the upper cover 3 and the interior of the furnace body 1 can be initially sealed, preventing dust and impacts generated by explosions from leaving the accommodating space 2, thereby improving the sealing effect.

[0040] As a further technical solution, the top of the furnace body 1 has a staggered platform 19, and the chamfer 18 of the top of the furnace body 1 is located above the staggered platform 19. After the upper cover 3 is installed, the upper cover 3 abuts against the staggered platform 19.

[0041] In this embodiment, the design of the offset 19 and the chamfer 18 are both ways to improve the bearing capacity and sealing performance of the furnace body 1. Through the coordination of the offset 19 and the chamfer 18, the sealing performance can be further improved while ensuring the integrity of the appearance.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
