Description
Technical Field
The invention relates to drying equipment, in particular to a dryer.
Background
The air of the air return system of the existing dryer has both heat energy and water vapor, and when the air return system is recycled for multiple times, the water vapor is more and more, the drying time is long, and the drying effect is poor. On the other hand, the heating system of the dryer has a small ratio of the total area of the air outlets of all the hot air sending fans in the drying room to the sectional area of the hot air sending direction in the drying room, so that the drying speed of the dried materials at each position is different.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the dryer which is higher in drying efficiency and more uniform in drying speed of the dried materials.
The invention adopts the following technical scheme.
The utility model provides a drying-machine, has baking house, heating system and return air system, has a moisture device among its characterized in that return air system, the moisture device includes evaporimeter, compressor, condenser, throttling arrangement, water-cooling interchanger, water pump and water tank, and the evaporimeter links to each other with the compressor, and the compressor links to each other with the condenser, and the condenser links to each other with throttling arrangement, and throttling arrangement links to each other with the evaporimeter, and the other water-cooling interchanger that has of evaporimeter, water-cooling interchanger link to each other with the water pump, and the water pump links to each other with the water tank, and the water tank links.
The heating system is provided with an air source heat pump, and a PTC electric heater is arranged beside a condenser of the air source heat pump.
The number of the hot air sending fans of the drying room is more than 2.
And a cooling fan is arranged beside the water tank.
The ratio of the total area of the air outlets of all the hot air supply fans to the sectional area of the drying room in the hot air supply direction is 0.3-0.45.
Compared with the prior art, the invention has the advantages of higher drying efficiency and more uniform drying speed of the dried materials.
Drawings
Fig. 1 is a schematic structural view of a moisture removal device according to an embodiment of the present invention.
Fig. 2 is a schematic structural view of the heating chamber.
Fig. 3 is a schematic structural view of a horizontal section of the drying room.
Detailed Description
The invention is described in further detail below with reference to the figures and examples.
As shown in fig. 1-3, a dryer has a drying room 25, a heating system, and an air return system. 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, condensation 6 links to each other with throttling arrangement 11 through pipe B9, throttling arrangement 11 passes through pipe D13 and links to each other with evaporimeter 5, there is water-cooling exchanger 3 by evaporimeter 5, water-cooling exchanger 3 passes through pipe F16 and links to each other with water pump 17, water pump 17 passes through pipe G18 and links to each other with water tank 19, 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.
The drying room 25 is provided with 4 hot air sending fans 24, the ratio of the total area of air outlets of the 4 hot air sending fans 24 to the sectional area of the drying room in the hot air sending direction is 0.37, and the drying speed of the dried materials at all positions in the drying room 25 is uniform.
