Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1-3, a continuous dryer comprises a drying room 26, a heating system, an air return system, a heat-conducting air hole plate and a material conveyor 29, wherein the material conveyor 29 is positioned below the heat-conducting air hole plate, hot air is simultaneously fed into a hot air inlet a24 and a hot air inlet B35 which are positioned above the heat-conducting air hole plates at two ends of the drying room, and an included angle between the heat-conducting air hole plate C25, the heat-conducting air hole plate D27, the heat-conducting air hole plate E28 and the heat-conducting air hole plate F30 and a horizontal plane is 38 degrees. The included angles between the heat conduction air hole plate G34, the heat conduction air hole plate H33, the heat conduction air hole plate I32 and the heat conduction air hole plate J31 and the horizontal plane are 38 degrees. The ratio of the total area of the holes of the heat conducting air hole plate C25 or the heat conducting air hole plate G34 to the area of the heat conducting air hole plate per se is 0.4, the ratio of the total area of the holes of the heat conducting air hole plate D27 or the heat conducting air hole plate H33 to the area of the heat conducting air hole plate per se is 0.35, the ratio of the total area of the holes of the heat conducting air hole plate E28 or the heat conducting air hole plate I32 to the area of the heat conducting air hole plate per se is 0.25, and the ratio of the total area of the holes of the heat conducting air hole plate F30 or the heat conducting air hole plate J31 to the area of the heat conducting.
There is a moisture removal device in the return air system, moisture removal device has evaporimeter 5, evaporimeter 5 links to each other with compressor 12 through pipe E14, compressor 12 links to each other with condenser 6 through pipe C10, the other fan 7 of condenser 6, condenser 6 links to each other with throttling arrangement 11 through pipe B9, throttling arrangement 11 links to each other with evaporimeter 5 through pipe D13, there is water-cooling exchanger 3 by evaporimeter 5, water-cooling exchanger 3 links to each other with water pump 17 through pipe F16, water pump 17 links to each other with water tank 19 through pipe G18, water tank 19 passes through pipe A2 and links to each other with water-cooling exchanger 3, there is cooling fan 1 above water tank 19. When waste heat air of the air return system enters the moisture removing device from the air return inlet 4, under the action of the evaporator 5 and the water-cooling exchanger 3, water vapor is condensed into water and flows out of the water outlet 15, and the water of the water-cooling exchanger is sent into the water tank 19 by the water pump 17 and flows into the water-cooling exchanger 3 after being cooled by the cooling fan 1. The dehumidified residual air is sent out from the return air outlet 8 by the fan 7.
The heating chamber of the heating system is provided with an air inlet 20, an air outlet 23 and a PTC electric heater 23 beside a condenser A21 of the air source heat pump.
