Embodiment Construction

[0013] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0014] Such as figure 1 The shown soft clapboard penetrating counterflow dryer includes a dryer box 11 and an induced draft fan A. The two ends of the dryer box 11 are respectively provided with an exhaust hood 6 and an air intake hood 12, and the exhaust hood 6 is connected to the induced draft fan A. , the induced draft fan A is evacuated after being connected to the evaporator 22 of the heat pump system through the cyclone dust collector 21; The air inlet hood 12 is connected through the condenser 26; the driving roller 1 and the driven roller 13 in the dryer box 11 drive the sieve plate steel belt 3 to pass through, and the sieve plate steel belt 3 divides the dryer box 11 into upper The upper and lower cabinets are equipped with multiple vertically arranged soft partitions 4 to separate the upper and lower cabinets into several units. The soft partitions 4 lightly...

Abstract

The invention discloses a soft partition board type through counter-flow drier. An air suction hood and an air inlet hood are arranged at two ends of a casing of the drier respectively, the air suction hood is connected with an induced draft fan, and the induced draft fan is emptied after being connected with an evaporator of a heat pump system through a cyclone dust collector; the evaporator of the heat pump system is connected with a main unit through a refrigerant pipe, and the main unit is connected with a condenser through a refrigerant pipe; an air outlet end of an air blower is connected with the air inlet cover through the condenser; multiple soft partition boards vertically arranged in the casing of the drier divide an upper casing body and a lower casing body into a plurality of units respectively; the soft partition boards press materials softly and block air currents completely, and material conveying is not influenced; axial flow fans are arranged in the units, the upper fans face downward and the lower fans face upward. Through counter-flow drying of materials is ingeniously realized through the induced draft fan, the soft partition boards and the axial flow fans, the drying efficiency is improved, the drying speed is increased, and the energy consumption is also reduced; heat pump type tail gas heat recovery is suitable for heat recovery of tail gas with a lower temperature efficiently and conveniently.

Description

technical field [0001] The invention relates to a dryer, in particular to a soft partition type penetrating countercurrent 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 penetration and countercurrent 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. Con...
