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.
[0017] Please see Figures 1-3This utility model provides a technical solution: a heating furnace for producing silicone sealant, comprising a heating furnace body 1 and a conveyor 5. A sealing cover plate 9 is provided at the upper end of the heating furnace body 1, and feed pipes 4 are spaced through the sealing cover plate 9. A feed control valve 401 is installed on the feed pipes 4, and a storage cylinder 6 is connected to the upper end of the feed pipes 4. A heating mechanism 102 is embedded in the inner wall of the heating furnace body 1, and an insulation layer 101 is also provided on the inner wall of the heating furnace body 1. The storage cylinder 6 is a vertically penetrating conical cylinder, and the upper end of the storage cylinder 6 is connected to the conveyor 5. The material feeder 5 has a discharge end that is connected. This structure allows for temporary storage of raw materials through the storage cylinder 6, enabling the metered material to be preheated within the storage cylinder 6 for better melting and mixing. The heating furnace body 1 is equipped with a stirring shaft 3. A stirring rod 301 and a scraper 302 are welded to the side of the stirring shaft 3. The scraper 302 is fitted with the inner wall and bottom of the heating furnace body 1 with a clearance. This structure, through the cooperation of the stirring rod 301 and the scraper 302, can mix and stir the raw materials used in the production of silicone sealant, ensuring the raw materials are properly melted and mixed. After heating and melting, the mixture can be uniformly mixed. A stirring motor 7 is installed on the upper end of the sealing cover plate 9, and the stirring motor 7 is fixed to the stirring shaft 3 via a coupling. In this structure, the stirring motor 7 is positioned between the storage cylinders 6, without interference. The stirring motor 7 can drive the stirring shaft 3 to rotate under the positioning of the sealing cover plate 9. A discharge mechanism 2 is installed at the bottom of the heating furnace body 1. A gas guide ring pipe 8 is provided above the sealing cover plate 9, and the gas guide ring pipe 8 is connected to the feed pipe 4. The feed pipe 4 is inclined downwards, and its outlet faces the stirring shaft 3. This structure... The material can be fed through the feed pipe 4 and then collected in the central area to facilitate the melting and mixing of the material. The outer side of the heating furnace body 1 is provided with an exhaust purification box 10, which is connected to the gas guide ring pipe 8. The part of the feed pipe 4 connected to the gas guide ring pipe 8 is provided with evenly spaced connecting holes 402, and the gas guide ring pipe 8 is located below the feed control valve 401. In this structure, during the heating and melting of the material, the gas generated in the heating furnace body 1 can enter the exhaust purification box 10 through the gas guide ring pipe 8 to achieve gas purification.
[0018] Working Principle: When using this silicone sealant production heating furnace, various raw materials are first metered and conveyed by the feeder 5, allowing them to enter the storage cylinder 6. The feed control valve 401 is then opened, allowing the raw materials to enter the heating furnace body 1 through the feed pipe 4. The heating furnace body 1 heats and melts the raw materials through the heating mechanism 102. Simultaneously, the stirring motor 7 drives the stirring shaft 3, which in turn rotates the stirring rod 301 and scraper 302, ensuring uniform heating and mixing of the raw materials. During the heating process, metering and feeding are performed again, while ensuring that the feed control valve 401 is closed. The heating furnace body 1... The heat inside is conducted to the storage cylinder 6 through the feed pipe 4, achieving preheating of the internal structure of the storage cylinder 6. The gas generated by heating inside the furnace body 1 enters the gas guide ring pipe 8 through the connecting hole 402, and then connects to the exhaust purification box 10. The gas is purified by the adsorption and purification filling material such as activated carbon set in the exhaust purification box 10. The sealing cover plate 9 plays a sealing role, and the heat insulation layer 101 can reduce the heat loss from the sides and bottom. After heating is completed, the material can be discharged through the discharge mechanism 2. When heating and melting again, the preheated raw material can be sent back to the furnace body 1, thus completing a series of operations.
