Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a heating device for drying equipment. Background Technology

[0002] In fields such as agricultural product processing, drying of industrial products and materials, and food preservation, drying equipment is the core equipment for removing moisture from materials and ensuring product quality and storage stability. Heating devices are the key to providing hot air to drying equipment and directly determine drying efficiency and drying effect.

[0003] Common heating equipment, such as the industrial hot air furnace proposed in authorization announcement number CN223077140U, includes a furnace body, a furnace cover, a burner, and a fan. The burner is installed at the combustion end of the furnace body, and the furnace cover is installed at the outlet end of the furnace body. The flow guiding structure of this hot air furnace is arranged in the air supply channel and does not directly contact the high-temperature flame and flue gas of the burner. This can reduce the dependence of the flow guiding structure on high-temperature resistant materials and save on construction costs.

[0004] However, the aforementioned hot air furnace still has certain drawbacks in its use. While air is directly introduced into the furnace chamber, it often contains a large amount of dust and impurities. After prolonged use, these dust and particles adhere to the furnace surface, affecting heat exchange between the furnace and the air. Furthermore, these impurities and dust affect the cleanliness of the exhaust air, making it unsuitable for applications requiring high hot air cleanliness. To address these issues, we provide a heating device for drying equipment to solve the problems mentioned above. Utility Model Content

During operation, the natural gas burner 18 is started to burn inside the furnace body 13 to heat the furnace body 13. The high-temperature flue gas during combustion enters the heat exchange flue 14 through the connecting box 20, so that the heat exchange flue 14 is in a high-temperature state. The high-temperature flue gas through the heat exchange flue 14 finally enters the exhaust box 19 and is then discharged from the exhaust pipe 2. Since the furnace body 13 and the heat exchange flue 14 are in a high-temperature state, the circulating air will be heated to form the required hot air when it passes through.

[0030] The working principle of this utility model is as follows: When working, the fan 7 starts to draw in the air in the air inlet box 5 and delivers the air into the heat insulation box 1. The air filter plate 6 can filter the air entering the air inlet box 5, blocking impurities and dust in the air and ensuring the cleanliness of the air entering the air inlet box 5. The air blown into the heat insulation box 1 is guided by the air guide plate 12, blown over the surface of the furnace body 13, and then flows through the heat exchange flue 14. The circulating air is heated by the furnace body 13 and the heat exchange flue 14 to form hot air, and then enters the right-angle air outlet duct 3 through the air outlet hopper 4 and is blown out from the right-angle air outlet duct 3 to form hot air.
