Abstract

The invention discloses a heat pump type tunnel drying device with a baffling dust removal function. A trolley is arranged on a rail of a tunnel, long-shaft fans for internal circulation are arranged in the tunnel, vanes of each long-shaft fan are long-strip-shaped, the section of each vane is in a hollow wedge shape centrosymmetric about the axial radial direction of an impeller, two ends of each vane are inserted into end plates, and each long shaft is fixedly connected with the corresponding end plates through spokes; an air suction hood and an air inlet hood are arranged at two ends of the tunnel adopting a sealed structure, the air suction hood is connected with an induced draft fan, and the induced draft fan is connected with an evaporator of a heat pump system through a dust remover and then emptied; the evaporator of the heat pump system is connected with a main unit, and the main unit is connected with a condenser; an air outlet end of an air blower is connected with the air inlet hood through the condenser; the induced draft fan and the impeller of the long-shaft fans are designed to adopt a hollow symmetric structure and are light, ingenious, solid and durable, and dust cannot be accumulated. Crossflow drying and waste heat recovery of a heat pump are especially suitable for low-temperature drying, nutritional ingredients of thermosensitive substances can be prevented from being damaged, and the system can finish drying, dust removal and heat recovery efficiently at low energy consumption.

Description

technical field [0001] The invention relates to a drying device, in particular to a baffle dust removal heat pump type tunnel drying device. 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 impelle...
