Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically to a flange interface structure for a pilot-scale vertical tubular furnace suitable for high-cleanliness reaction environments. Background Technology

[0002] In high-cleanliness pilot-scale production scenarios, multiple atmospheres need to be introduced into a vacuum environment with a large diameter (greater than 50 mm) for reaction. The technology here requires the gas to slowly and uniformly contact the sample, forming a deposition on the sample surface. Traditional horizontal tube furnaces in new material synthesis suffer from problems such as material contact with the reaction tube wall and uneven atmosphere flow, making it difficult to meet the requirements of suspension reactions under high-cleanliness conditions. This results in a low sample yield and wasted raw materials. Therefore, a vertical approach is necessary. However, because the tube diameter is so large, while vertical furnaces can suspend materials, the high-temperature flange structure at the top bears a heavy heat load, causing the flange to overheat, affecting equipment lifespan, melting the sealing ring, contaminating the inner wall, reducing airtightness, and even posing safety hazards. Utility Model Content

[0003] To address the problem of heat damage to existing flange interfaces, this invention provides a pilot-scale vertical tubular furnace flange interface structure suitable for high-cleanliness reaction environments.

[0004] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0005] A pilot-scale vertical tubular furnace flange interface structure suitable for high-cleanliness reaction environments includes a vertical tubular furnace body, a heat dissipation mechanism installed on one side of the top surface of the furnace body, and a furnace tube inserted into the furnace body on the side near the heat dissipation mechanism; a flange assembly installed at the top of the furnace tube, the flange assembly including a flange body, the flange body having a hollow chamber inside, and water-cooling interfaces connected to both sides of the hollow chamber; and a heat shielding plug structure installed inside the furnace tube, with hooks installed on both sides of the top surface of the heat shielding plug structure, and hook assemblies on both sides of the bottom surface of the flange body that engage with the hooks.

[0006] Furthermore, the heat shield plug structure includes several circular partitions, and the outer walls of the several circular partitions are respectively provided with perforations. The top surface of the flange assembly is respectively provided with airflow channels that match the perforations.

[0007] The beneficial effect of adopting the above-mentioned further solution is that the perforation provides space for the airflow channel to pass through, and at the same time, the airflow channel can also fix multiple sets of circular partitions in designated positions.

[0008] Furthermore, gaps are provided between the circular partitions.

[0009] The beneficial effects of adopting the above-mentioned further solutions are that they can enhance the heat shielding effect, reduce the conduction and radiation of heat in the furnace tube, and reduce the impact of heat on the flange assembly and other components.

[0010] Furthermore, the hook assembly includes a tie rod, the tie rod is welded to the bottom surface of the flange body, and a hook is installed at the bottom end of the tie rod.

[0011] The beneficial effects of adopting the above-mentioned further solutions are that they can withstand the weight of the heat shield plug structure; the hooks and buckles are connected to ensure that the heat shield plug structure is stably installed in the furnace tube and will not loosen or fall off during equipment operation, thus ensuring the sealing of the high-cleanliness reaction environment and the safety of equipment operation.

[0012] Furthermore, the heat dissipation mechanism includes a mounting base, one side of which has a circular hole, and a fan is installed inside the circular hole.

[0013] The beneficial effect of adopting the above-mentioned further solution is that it can quickly dissipate the heat generated by the furnace body, accelerate air circulation, and reduce the temperature of the flange assembly.

[0014] Furthermore, a filter screen is embedded on one side of the circular hole, and there is a gap between the filter screen and the fan.

[0015] The beneficial effect of adopting the above-mentioned further solution is that it can effectively intercept dust, impurities and other particulate matter in the air, prevent them from entering the heat dissipation mechanism, and avoid the fan blades being covered by dust, which would affect the heat dissipation efficiency.

[0016] Furthermore, the furnace tube is made of transparent quartz.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it allows operators to directly observe the state of the reactants inside the furnace tube, the reaction process, and temperature changes, without having to open the furnace tube, reducing the risk of external contamination and ensuring a highly clean reaction environment.

[0018] Furthermore, the top surface of the heat dissipation mechanism is flush with the top surface of the flange assembly.

[0019] The advantage of adopting the above-mentioned further solution is that the airflow driven by the heat dissipation mechanism can flow directly to the vicinity of the flange assembly, thereby improving the cooling efficiency.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This pilot-scale vertical tubular furnace flange interface structure, suitable for high-cleanliness reaction environments, utilizes a combination of a heat dissipation mechanism, flange assembly, and heat shielding plug structure to reduce heat transfer to the flange interface structure. This effectively prevents the internal sealing ring from melting due to high temperatures, while simultaneously improving combustion efficiency. A significant amount of heat is retained within the furnace body, reducing the frequency of replacements and maintenance, and increasing pilot-scale production efficiency. The blower operation of the heat dissipation mechanism accelerates airflow around the flange interface structure, achieving air cooling. Combined with the water-cooled interface in the flange assembly, which connects to coolant, water cooling circulation allows for cooling and heat dissipation from within the flange interface structure. Furthermore, the heat shielding plug structure provides insulation, effectively preventing heat from rising and impacting the flange. Attached Figure Description

Detailed Implementation

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.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a pilot-scale vertical tube furnace flange interface structure suitable for high-cleanliness reaction environments, including a vertical tube furnace body 100, a heat dissipation mechanism 200 installed on one side of the top surface of the vertical tube furnace body 100, and a furnace tube 300 inserted into the vertical tube furnace body 100 near the heat dissipation mechanism 200; a flange assembly 400, which is installed at the top of the furnace tube 300, and includes a flange body 4001, which has a hollow cavity inside, with water-cooling interfaces 4002 connected to both sides of the hollow cavity; and a heat shielding plug structure 600. Installed inside the furnace tube 300, the heat shielding plug structure 600 has hooks 700 installed on both sides of its top surface. The flange body 4001 has hook assemblies 500 on both sides of its bottom surface that connect with the hooks 700. The blower operation of the heat dissipation mechanism 200 accelerates the airflow around the flange interface structure, achieving air cooling. Combined with the water cooling interface 4002 in the flange assembly 400 connecting to coolant, water cooling circulation is achieved, cooling the flange interface structure from within. Furthermore, the heat shielding plug structure 600 provides insulation, effectively preventing heat from rising and impacting the flange. The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] As an embodiment of this utility model, the heat shielding plug structure 600 further includes a plurality of circular partitions 6001, and the outer walls of the plurality of circular partitions 6001 are respectively provided with perforations 6002. The top surface of the flange assembly 400 is respectively inserted with airflow channels 4003 that match the perforations 6002. The perforations 6002 provide space for the airflow channels 4003 to pass through. At the same time, the airflow channels 4003 can also fix multiple sets of circular partitions 6001 in designated positions. The gaps between the plurality of circular partitions 6001 can enhance the heat shielding effect, reduce the conduction and radiation of heat in the furnace tube, and reduce the impact of heat on the flange assembly and other components.

[0031] As one embodiment of this utility model, the hook assembly 500 further includes a pull rod 5001. The pull rod 5001 is welded to the bottom surface of the flange body 4001, and a hook 5002 is installed at the bottom end of the pull rod 5001, which can bear the weight of the heat shield plug structure 600. The hook 5002 is connected to the hook 700 to ensure that the heat shield plug structure is stably installed in the furnace tube and will not loosen or fall off during equipment operation, thus ensuring the sealing of the high-cleanliness reaction environment and the safety of equipment operation.

[0032] As an embodiment of this utility model, the heat dissipation mechanism 200 further includes a fixed base 2001. A circular hole is provided on one side of the fixed base 2001, and a fan 2002 is installed inside the circular hole. This fan can quickly dissipate the heat generated by the furnace body, accelerate air circulation, and reduce the temperature of the flange assembly 400. A filter screen 2003 is embedded in one side of the circular hole. A gap is provided between the filter screen 2003 and the fan 2002, which can effectively intercept dust, impurities, and other particulate matter in the air, prevent them from entering the heat dissipation mechanism, and avoid the fan blades being covered by dust, thus affecting the heat dissipation efficiency.

[0033] As an embodiment of this utility model, the furnace tube 300 is further designed as a transparent quartz tube, which allows operators to directly observe the state of the reactants inside the furnace tube, the reaction process, and temperature changes, without having to open the furnace tube, thus reducing the risk of external contamination and ensuring a highly clean reaction environment.

[0034] As an embodiment of this utility model, the top surface of the heat dissipation mechanism 200 is flush with the top surface of the flange assembly 400, so that the airflow driven by the heat dissipation mechanism 200 can flow directly to the periphery of the flange assembly 400, thereby improving the cooling efficiency.

[0035] Specifically, the working principle of this pilot-scale vertical tubular furnace flange interface structure suitable for high-cleanliness reaction environments is as follows: During use, the fan 2002 of the heat dissipation mechanism 200 operates within the circular hole of the fixed base 2001, drawing in and blowing out surrounding air, accelerating the airflow around the flange interface structure, and achieving air cooling. Simultaneously, the flange assembly 400 connects to coolant through the water-cooling interface 4002. The coolant circulates within the hollow chamber of the flange body 4001, carrying away heat from the inside, achieving water cooling. The heat shield plug structure 600 is securely installed inside the furnace tube 300 by hooking the hook 5002 of the bottom hook assembly 500 of the flange body 4001 via a hook 700. The gaps between its several circular baffles 6001 and its own thermal insulation performance effectively prevent the rise of heat inside the furnace from impacting the flange assembly. The reaction gas enters the furnace tube 300 through the airflow channel 4003 on the top surface of the flange assembly 400, passing through the perforations 6002 on the circular baffles 6001, and undergoes the reaction. Operators can visually observe the reaction status of materials inside the furnace tube 300 through the transparent quartz material and adjust the reaction parameters in a timely manner. The design of the heat dissipation mechanism 200 having its top surface flush with the top surface of the flange assembly 400 allows the air-cooled airflow to act more smoothly around the flange assembly, improving the overall heat dissipation efficiency and ensuring the stable operation of the flange interface structure in a high-cleanliness reaction environment.
