Cyclone dust removal heat pump type drying room

Abstract

The invention discloses a cyclone dust removal heat pump type drying room. An internal recycle long-shaft draught fan is arranged in the drying room and comprises a long shaft and blades; the blades are long-strip-shaped; the cross section of each blade is centrosymmetric hollow reverse drop-shaped in the radial direction of an impeller shaft; two ends of the blades are inserted in end discs; the long shaft is connected with and fixed with the end discs through spokes; a draught hood and an air inlet hood are arranged at two ends of the drying room; the draught hood is connected with an induced draft fan; the induced draft fan is connected with the evaporator of a heat pump system via a cyclone dust collector for evacuation; the evaporator of the heat pump system is connected with a host machine; the host machine is connected with a condenser via a refrigerant pipe; the air outlet end of an air blower is connected with the air inlet hood via the condenser; the induced draft fan and the impeller of the long-shaft draught fan are arranged into hollow symmetrical structures, do not accumulate dust, and are firm and durable. The heat pump dries in a cross flow manner, recycles residual heat, is particularly suitable for being adopted by a lower drying temperature system, prevents nutritional ingredients of thermosensitive substances from being destroyed, and completes drying, dust removal and heat recovery in an efficient and low energy consumption manner.

Description

technical field [0001] The invention relates to a drying room, in particular to a cyclone dedusting heat pump drying room. Background technique [0002] Due to its mature technology, strong adaptability, low operating cost and strong reliability, the hot air dryer is still one of the main preferred equipment for drying materials. If the tail heat can be effectively recovered during the hot air drying process, it will be beneficial to improve Drying efficiency and the realization of energy saving and emission reduction are of particular importance. [0003] The fan is the key equipment of the hot air dryer. The fan is generally a centrifugal fan. The continuous, stable and reliable operation of the fan is very important for the dehumidification and air circulation of the dryer. Because most of the occasions where the dryer is used contain a certain amount of dust , When the fan is working, when the air flow passes through the high-speed rotating fan impeller, due to the cent...

AI Technical Summary

Problems solved by technology

Once some hardened dust is shaken off by vibration, it will immediately leave the dynamic rotation balance of the fan, and then generate strong vibration, which may cause serious personnel and equipment safety accidents
