Description

Technical Field

[0001] This utility model relates to the field of drying device technology, specifically to a high-efficiency heat dissipation hot air drying device. Background Technology

[0002] Hot air drying, also known as "instant drying," involves direct contact between the heating medium (air, inert gas, exhaust gas, or other hot gas) and the solid particles to be dried, suspending the particles in the fluid. This results in a large contact area between the two phases, enhancing the heat and mass transfer process, and is widely used in drying unit operations for granular materials.

[0003] A search revealed an existing patent (CN214950365U) that discloses a spiral-vented sweater drying device, comprising a drying chamber. A cyclone generator is fixedly connected to the bottom of the drying chamber, and support feet are evenly fixed to the side wall of the cyclone generator. A heater is located in the lower left part of the drying chamber, and the outlet of the heater is fixedly connected to the cyclone generator via a duct. A bent pipe is fixedly connected to the top of the drying chamber, and an air inlet pipe is fixedly connected to the air inlet of the heater. A moisture-absorbing tank is fixedly connected between the air inlet pipe and the bent pipe. A horizontal frame extending to the right is fixedly connected to the upper right part of the drying chamber. Rotating shafts are vertically rotatably connected to the right side of the horizontal frame and the bottom left side of the drying chamber's inner cavity. Rotating wheels are fixedly fitted to the lower ends of the two sets of rotating shafts, and a belt ring is nested between the two sets of rotating wheels. Hooks are evenly fixed to the outer side wall of the belt ring. A motor capable of driving the right rotating shaft is fixedly installed on the top of the horizontal frame. A door is located on the right side of the drying chamber. This invention uses a motor to drive the belt ring to rotate, which allows for the displacement of the sweater hook, facilitating the drying and unloading of sweaters. A cyclone generator increases the flow rate of the warm air, thereby improving the drying efficiency of the sweaters. A moisture-absorbing tank dehumidifies the moisture absorbed by the warm air from the sweaters, allowing for the reuse of the warm air. This reduces the power consumption of the heater, thus lowering energy consumption and reducing emissions.

[0004] However, the above schemes lack heat recovery and consume a lot of energy. Early heat recovery devices were mainly based on simple heat exchange principles, such as tubular heat exchangers. However, these traditional devices have certain limitations in terms of heat recovery efficiency and applicability.

[0005] In view of this, the present invention proposes a hot air drying device with high efficiency in heat dissipation. Utility Model Content
