Abstract

The invention discloses a hot wind type penetration reverse flow drying machine capable of recycling tail heat. A draught hood and a wind inlet hood are arranged at the two ends of a case body of the drying machine respectively. The draught hood is tangentially connected with a cyclone dust removing tail heat efficient recoverer through a draught fan and then evacuation is conducted. A blast blower is connected with the wind inlet hood through a tube type heat exchanger and a steam fin heater. A draught fan impeller is provided with hollow inverse-drop-shaped blades, and a back plate is of a dishing structure. The outline of the draught fan is an involute. According to the hot wind type penetration reverse flow drying machine capable of recycling tail heat, tail heat recovery and dust removal are creatively integrated, the cyclone dust removing tail heat efficient recoverer is designed, the equipment investment is reduced, and the working efficiency is improved. By means of the draught fan, a soft partition plate and an axial fan, penetration type reverse flow drying is ingeniously achieved, and the working efficiency is improved. The blades are in the hollow inverse drop shape, the back plate is of the dishing structure, and therefore real-time cleaning of dust on the impeller is achieved, the strength of the impeller of the draught fan is improved, stability is enhanced, accidents caused by dust accumulation are effectively eradicated, and the application prospects are wide.

Description

Technical field [0001] The invention relates to a dryer, which specifically guides the tail heat recovery hot air type penetrating countercurrent dryer with no dust accumulation by the fan. Background technique [0002] The hot air dryer is still one of the main preferred equipment for material drying due to its mature technology, strong adaptability, low operating cost, and strong reliability. If the material can be penetrated and countercurrently dried during the hot air drying process, And effective recovery of tail heat is of special significance for improving drying efficiency and realizing energy saving and emission reduction. [0003] The induced draft fan is the key equipment of the hot-air dryer. The induced draft fan is generally a centrifugal fan. The continuous, stable and reliable operation of the induced draft fan is critical to the dryer's moisture removal. Since most of the dryers are used, they contain a certain amount of dust. , When the induced draft fan is work...
