Description

Technical Field

[0001] The utility model relates to the technical field of heat recovery, and more specifically, to a baking device with a heat recovery mechanism. Background Art

[0002] Dryers can be divided into two types: industrial and civil. Industrial dryers are also called drying equipment or dryers. Civil dryers are a type of washing machinery. They are generally used to remove moisture from clothing and other textiles after washing and dehydration. Dryers have several modes such as belt drying, drum drying, box drying, tower drying, etc. The heat sources include coal, electricity, gas, etc. The materials are dried in hot air airflow and radiation processes. Hot air drum drying is a process in which the hot air flow moves forward from the tail and fully contacts the material. The heat transfer is fully utilized through heat conduction, convection, and radiation, and the heat energy is directly transferred to the material, so that the moisture of the material is continuously evaporated in the cylinder. The induced draft device at the feed inlet draws out a large amount of moisture and wet air flow to prevent secondary pollution caused by dust discharge. The material movement is promoted through internal spiral stirring, sweeping, and copying to complete the entire drying process. However, in the existing technology, when drying is performed through a dryer, the drying structure is single, the drying heat is directly lost, and secondary heat exchange cannot be performed, resulting in heat waste and poor drying effect.

[0003] Chinese utility model disclosure specification CN217929450U discloses a mesh belt dryer with heat recovery function, including a drying box with a drying chamber and a heat recovery fan, the heat recovery fan including an exhaust duct with an air inlet end connected to the drying chamber, an air suction duct with an air outlet end connected to the drying chamber, a heat exchange structure with two ends placed in the exhaust duct and the air suction duct, a first fan arranged in the exhaust duct and a second fan arranged in the air suction duct, the exhaust duct and the air suction duct are respectively provided with a one-way valve that only allows gas to flow from the air inlet end to the exhaust end, which can effectively prevent the hot air in the drying chamber from flowing out after the fan is stopped, but this arrangement can only effectively prevent the hot air in the drying chamber from flowing out after the fan is stopped, but cannot make the drying heat be exchanged and recycled for the second time, resulting in heat waste and poor drying effect.

[0015] 2. The utility model provides a V-shaped heating block. When drying starts, the outside air is pumped by the first vacuum pump, so that the air enters the first groove, and the air is filtered by the filter. At the same time, when the air enters the second groove through the one-way valve mechanism, the multiple V-shaped heating blocks are heated by the heat conduction block, and the contact with the air is increased by the V-shaped heating block. At the same time, the hot air inside the drying box is pumped by the second vacuum pump, so that the hot air inside the drying box enters the second groove again through the one-way valve mechanism, and the air is heated again by the V-shaped heating block, and then enters the drying box for drying again, so as to improve the air temperature and humidity exchange efficiency and avoid insufficient heating of the air, which leads to poor drying effect.
