The invention discloses a heat pump type tail heat utilization penetrating countercurrent fluidization dryer. The upper part of the drying tower is provided with a material-sealed screw feeder, and the bottom is provided with an air lock discharger. The upper part of the drying tower is connected with an induced draft fan, and the induced draft fan passes through The cyclone dust collector is connected to the evaporator of the heat pump system and then emptied; the evaporator of the heat pump system is connected to the host through the refrigerant pipe, and the host is connected to the condenser through the refrigerant pipe; the outlet end of the blower is connected to the lower part of the drying tower through the condenser; the impeller of the induced draft fan has The blade is a hollow wedge-shaped structure; the contour line of the induced draft fan is an involute. The invention cleverly and perfectly realizes the penetration, countercurrent, boiling and fluidized drying of the material by setting the sieve hole cone cover, the sieve hole cone disc, the drop pipe, the telescopic vibration transmission shaft and the conical plug, completely surpassing It adopts the classic boiling countercurrent drying mode, which is more energy-saving, with higher drying quality and lower fan power consumption; the heat pump exhaust heat utilization is especially suitable for heat recovery with low exhaust gas temperature.
Description
technical field [0001] The invention relates to a dryer, in particular to a heat pump tail heat utilization penetrating countercurrent fluidization dryer in which a fan does not accumulate dust. Background technique [0002] People generally refer to drying with a drying temperature below 60 degrees Celsius as low-temperature drying. Low-temperature drying is widely used in the drying of heat-sensitive materials such as crop seeds, Chinese medicinal materials, and biological products. Due to its mature technology, strong adaptability, low operating cost and high reliability, hot air dryer is still one of the first choice equipment for low temperature drying. Low-temperature drying is less likely to utilize tail heat due to the lower temperature of exhaust gas. If the penetrating countercurrent fluidized drying of materials can be realized in the hot-air low-temperature drying process, and the tail heat can be effectively recovered, it will be of great significance for impro...
