Description

Technical Field

[0001] The utility model relates to the technical field of flash drier, and more specifically to an air inlet regulating device for a flash drier. Background Art

[0002] Flash dryer is a drying equipment commonly used to process suspended or powdered materials. Its working principle is based on the rapid evaporation and drying process. Since the hot air directly contacts and blows the wet material, the flash dryer can quickly evaporate the moisture in the wet material in a short time. It is suitable for drying a variety of powdered or granular materials, including raw material processing in the chemical, food, pharmaceutical and other industries.

[0003] After searching, a Chinese patent with application number CN202023231021.4 discloses a flash dryer, which is recycled through a cyclone separator and a dust collector connected to the top of a flash drying chamber. The crushing mechanism crushes the large pieces of material to produce a large amount of fine powdered material. These powdered materials can easily enter the bearing seat of the crushing mechanism, causing the bearing seat to lock, which makes maintenance or replacement inconvenient, seriously affecting the normal operation of the flash dryer. The blade of the crushing mechanism and the driving mechanism are separated by a dust cover, and the dust cover covers and seals the bearing seat in the driving mechanism, thereby preventing the powdered material from entering the bearing seat. An airtight sealing seat is provided to increase the airtight sealing function of the dust cover, thereby effectively improving the sealing of the dust cover and the shaft assembly.

[0004] The precise control of air intake by the flash dryer is a key factor affecting the drying effect and efficiency. During use, the flash dryer adopts the traditional pipeline direct current air intake method, and the air intake volume is inconvenient to control, which may lead to insufficient drying or over-drying, affecting product quality. At the same time, when the equipment fails or the motor cannot work normally under certain circumstances, if there is no backup adjustment method, it will seriously affect the production process.
