Abstract

The invention discloses a cyclone dust removal heat pump type tunnel drying device. A trolley is arranged on a track path of a tunnel, an internal recycling long-shaft fan is arranged in the tunnel, the long-shaft fan comprises a long shaft and blades which are all shaped like a long stripe, and the cross section of each blade is a shaped like a hollow reversed water drop symmetrical to the radial direction and the center of an impeller shaft; the two ends of each blade are inserted into end plates respectively, and the long shaft is connected and fixed with the end plates through spokes; the two ends of the closed type tunnel are provided with an air draft hood and an air intake hood respectively, the air draft hood is connected with a draft fan, and the draft fan is connected with an evaporator through a cyclone dust collector for emptying; the evaporator of a heat pump system is connected with a main machine which is connected with a condenser; an air outlet end of an air blower is connected into an air hood through the condenser; the draft fan and the long-shaft fan impellers are both designed to be of a hollow symmetrical structure, dirt retention does not exist, and lightness, firmness and durability are achieved. According to the cyclone dust removal heat pump type tunnel drying device, heat pump cross flow drying and tail heat recovery are suitable for being adopted by a low-temperature drying system, destroy to heat sensitive components can be prevented, and the system can complete drying, dust removing and heat recovery efficiently with low energy.

Description

technical field [0001] The invention relates to a tunnel drying device, in particular to a cyclone dedusting 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 im...
