[0002] Furnace door sealing devices are primarily used to ensure a good seal on the furnace door during operation, preventing leakage of high-temperature gases or heat radiation. They also facilitate operation and maintenance. Poor sealing can lead to high-temperature gas leakage, endangering operator safety. Automatic sealing devices improve safety levels, and a good seal effectively reduces heat loss, lowers energy consumption, and improves the energy efficiency of industrial furnaces.

[0003] Meanwhile, a novel automatic vacuum sealing furnace door device with application number CN201721133600.0 is disclosed, comprising a lifting mechanism and a furnace door assembly. The lifting mechanism is located at the front of the furnace body and connected thereto, and the furnace door assembly is located inside the lifting mechanism, with both sides of the furnace door assembly connected to the lifting mechanism. The furnace door assembly consists of an inner furnace door, a sealing shell, a furnace door frame, and a feeding unit. The inner furnace door is located inside the sealing shell, with the front of the inner furnace door connected to the interior of the sealing shell, and the front of the sealing shell connected to the furnace door frame. A feeding motor is mounted on the furnace door frame, and the feeding motor is connected to the sealing shell via a feeding screw.

[0004] However, the following problems were found in the implementation of the relevant technology: it cannot evenly cover the edge of the furnace door, thus failing to ensure the quality and effectiveness of the seal, which may lead to misalignment of the furnace body and temperature, potentially causing danger. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model achieves a sealing effect through the cooperation of a sealing door, mounting base, air pump, delivery pipe, and airbag. The air pump and airbag can quickly inflate and deflate, enabling a rapid and automated sealing and opening process, thus improving production efficiency. After inflation, the airbag can evenly cover the edge of the furnace door, forming a tight seal, reducing gas leakage, and ensuring the airtightness of the high-temperature environment inside the furnace.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides an automatic sealing device for an industrial furnace door, including a furnace body 1. A furnace door 2 is rotatably connected to the upper surface of the furnace body 1, and a sealing door 3 is fixedly connected to the lower surface of the furnace door 2. A mounting base 4 is fixedly connected to the upper surface of the furnace door 2 for mounting an air pump 5. The air pump 5 is also fixedly connected to the upper surface of the mounting base 4 for supplying gas. A delivery pipe 6 is fixedly connected to the output end of the air pump 5 for delivering gas. An air bladder 7 is fixedly connected to the end of the delivery pipe 6 away from the air pump 5 for sealing the gap between the sealing door 3 and the furnace body 1, thereby achieving a sealing effect. The air bladder 7 is fixedly connected to the sealing door 3. Next, a positioning structure 8 is provided on the furnace door 2 to ensure that the furnace door 2 fits tightly against the edge of the furnace body 1. A support plate 9 is fixedly connected to the upper surface of the furnace body 1, and an mounting plate 10 is fixedly connected to the lower surface of the support plate 9 for mounting a motor 11. The motor 11 is fixedly connected to the lower surface of the mounting plate 10 to provide power to the rotating shaft 12. The output end of the motor 11 is fixedly connected to the rotating shaft 12 to drive the rotating rod 13 to rotate. The rotating rod 13 is fixedly connected to the lower surface of the rotating shaft 12 to rotate the pressure plate 14. The end of the rotating rod 13 away from the rotating shaft 12 is fixedly connected to the pressure plate 14.

[0024] Specifically, the airbag 7 is made of silicone and is movably connected to the furnace body 1.

[0025] Furthermore, the lower section of the conveying pipe 6 is located inside the furnace door 2 and the sealing door 3. The furnace door 2 is equipped with a locking mechanism, which is an existing structure used to lock the furnace door 2.

[0026] Furthermore, the furnace body 1 is provided with a positioning groove 17 for connecting the positioning block 16, and the positioning groove 17 is semi-circular.

[0027] It is worth noting that the positioning structure 8 includes a fixing plate 15, which is fixedly connected to the furnace door 2.

[0028] It is worth noting that a positioning block 16 is fixedly connected to the lower surface of the fixing plate 15, and the positioning block 16 is movably connected to the positioning groove 17.

[0029] It is worth mentioning that the pressure plate 14 is movably connected to the rotating rod 13, and the lower side of the pressure plate 14 is rounded to better compress the fixing plate 15.

[0030] It is worth emphasizing that the rotation range of the pressure plate 14 is ninety degrees.

[0031] The furnace body 1, furnace door 2, air pump 5, and motor 11 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: During use, the furnace door 2 is closed by rotation driven and controlled by the power system. After closing, the air pump 5 on the mounting base 4 provides gas through the delivery pipe 6 to the air bag 7. The air bag 7 seals the gap between the sealing door 3 and the furnace body 1, thereby sealing the furnace door 2. When the furnace door 2 is closed, it is positioned by the positioning structure 8, that is, the positioning block 16 on the fixed plate 15 rotates to connect with the positioning groove 17 on the furnace body 1. When fully engaged, it is correct. Then, the motor 11 on the mounting plate 10 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the pressure plate 14 to rotate through the rotating rod 13. If the pressure plate 14 can rotate above the fixed plate 15, the positioning is accurate and the furnace door 2 is completely closed. The pressure plate 14 presses the fixed plate 15 to ensure the stability of the position of the furnace door 2, thereby ensuring the sealing of the whole process. Conversely, if the pressure plate 14 cannot rotate above the fixed plate 15, the furnace door 2 is not completely closed.
