Embodiment Construction

[0016] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0017] Such as figure 1 The tower-type penetrating countercurrent fluidized dryer shown includes a drying tower 1 and an induced draft fan A. The upper part of the drying tower is equipped with a material-sealed screw feeder 4, and the bottom is equipped with an air locker discharger 11; the upper part of the drying tower is connected to the induced draft fan. A, the induced draft fan A is emptied after being connected to the evaporator 22 of the heat pump system through the cyclone dust collector 21; The end is connected to the lower part of the drying tower through a condenser 26.

[0018] The top of the drying tower 1 is provided with a hydraulic expansion device 3 connected to the transmission shaft 2, the transmission shaft 2 runs through the tower body and can be driven up and down by the hydraulic expansion device 3, and the transmission shaft 2 is provided with...

Abstract

The invention discloses a tower type penetrating reverse flow fluidized direr. A material seal screw feeder is arranged at the upper portion of a drying tower. An air-lock valve discharger is arranged at the bottom of the drying tower. The upper portion of the drying tower is connected with an induced draft fan. The induced draft fan is connected with an evaporator of a heat pump system through a cyclone dust collector and then is evacuated. The evaporator of the heat pump system is connected with a host through a refrigerant pipe. The host is connected with a condenser through a refrigerant pipe. The air outlet end of an air blower is connected with the lower portion of the drying tower through the condenser. A plurality of layered repeated structures composed of sieve hole conical covers and sieve hole conical discs are arranged inside the drying tower. The sieve hole conical covers, the sieve hole conical discs, a discharging pipe, a stretchable vibration transmission shaft and a conical plug are arranged, so that penetrating, reverse flow, boiling and fluidization drying of materials are ingeniously and perfectly achieved, the classic boiling reverse flow drying mode is completely exceeded, more energy is saved, the drying quality is higher, and electricity consumption of the fans is lower; heat-pump-type tail heat recovery is particularly suitable for heat recovery at the low tail gas temperature.

Description

technical field [0001] The invention relates to a dryer, in particular to a tower type penetrating countercurrent fluidized dryer. 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 easy to recover tail heat due to the lower exhaust temperature. 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 improving drying efficiency and realizing energy saving and emission reduction...
