TL;DR: In this article, a heat pump type drying machine capable of utilizing waste heat and achieving penetrating countercurrent is presented. But the work efficiency of the system is limited by the number of axial fans and axial fan blades.
Abstract: The invention discloses a heat pump type drying machine capable of utilizing waste heat and achieving penetrating countercurrent. An air draft hood and an air inlet hood are arranged at the two ends of a drying machine case body respectively, the air draft 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 cyclone dust collector and then is emptied; the evaporator of the heat pump system is connected with a host through a refrigerant pipe, and the host is connected with a condenser through the refrigerant pipe; the air outlet end of an air blower is connected with the air inlet hood through a condenser; and multiple soft partition plates which are vertically arranged and divide an upper machine case body and a lower machine case body into multiple units are arranged in the drying machine case body. According to the heat pump type drying machine capable of utilizing the waste heat and achieving the penetrating countercurrent, by means of the induced draft fan, the partition plates and axial fans, the penetrating countercurrent drying is exquisitely achieved, and the work efficiency is improved; the heat pump type waste heat utilization is suitable for heat recovery of tail gas with lower temperature and is particularly efficient, convenient and rapid; and by means of the structure that blades are in a hollow and wedged shape and the backing plate is in a disc shape, real-time cleaning of dust on an impeller is achieved, the impeller strength of the induced draft fan is increased, the stability is enhanced, safety accidents caused by dust accumulation is effectively eradicated, and the application prospect is wide.
