The specific embodiment
As shown in Figure 1, the embodiment of the invention is to be made of following components: the cylinder (100) that is supported in above-mentioned body interior; One end is connected in the front side of this cylinder (100), and the other end is connected in the air (200) of the rear side of this cylinder (100); After being activated power, rotatable being arranged on the above-mentioned circulation pipe (200), the Air Blast fan (210) of the air in the forced circulation cylinder (100); Be arranged in the above-mentioned circulation pipe (200), heating is from the heater (220) of the air of this cylinder (100) discharge; Be arranged in this circulation pipe (200), the cooling water that utilizes the outside to supply with is removed the water-cooled heat exchanger (300) of moisture from the hot blast of the humidity of cylinder (100) discharge; Be arranged at the outer side of this air (200), cooling water and moisture are discharged to outside drainage arrangement.
Above-mentioned water-cooled heat exchanger (300) is to be made of shell (310), water pump (320), cooling water stream pipe (330).
Above-mentioned shell (310) is arranged on the air (200), and constitutes the outward appearance of water-cooled heat exchanger (300).
Be formed with a plurality of hot blasts on the above-mentioned shell (310) by hole (301).This hot blast by the effect of hole (301) is: the hot blast of the humidity that flows in air (200) is passed through.
Above-mentioned water pump (320) is used for cooling water is supplied to cooling water stream pipe (330) from the outside.According to embodiments of the invention, water pump (320) is arranged at the outside of air (200), and this water pump also can be arranged at air (200) inboard.
But, when above-mentioned water pump (320) is arranged at air (200) inboard,, therefore preferably water pump (320) is arranged at the outside of air (200) owing to when the hot blast process is provided with the position of above-mentioned water pump (320), can cause the hot blast loss.
There is flow of cooling water the inside of above-mentioned cooling water stream pipe (330).Its objective is in order to make the hot blast that flows in the humidity in the air (200) be contacted with cooling water stream pipe (330), begin dehumidifying.
Above-mentioned cooling water stream pipe (330) is arranged at shell (310) inside, and the one end is connected in water pump (320), and the other end is connected in drainage arrangement.
Cooling water flows in cooling water stream pipe (330), and and after moist hot blast finishes dehumidifying, be discharged to the outside by drainage arrangement.
Above-mentioned drainage arrangement is to be made of following components: the drip chamber (410) of accommodating above-mentioned cooling water and moisture; Cooling water and moisture that above-mentioned drip chamber (410) is inner are drawn into outside draining pump (420).
In an embodiment of the present invention, the cooling water stream pipe (330) of this water-cooled heat exchanger is arranged at the oblique line directions that is an angle with the hot blast flow direction.
This be for the hot blast that makes above-mentioned humidity via cooling water stream pipe (330) time, increase the area that contacts with cooling water stream pipe (330), the raising dehumidification rate.
The drying course of drying unit of the present invention is as described below:
In case drying operation begins, Air Blast fan (210) rotation, air will flow by air (200).After flow air is heated to be high temperature by heater (220), flow into cylinder inside, behind drying roller inside washed, the moisture that carries absorption from washed is discharged to circulation pipe (200).
At this moment, the air of discharge will become the hot blast of high temperature dampness, flow in the air (200).
The hot blast that flow to the hot blast above-mentioned water-cooled heat exchanger of process (300) of the high temperature humidity in the air (200) passes through hole (301).
At this moment, utilize above-mentioned water pump (320) will be used to the to dehumidify cooling water of hot blast of above-mentioned high temperature humidity to supply to cooling water stream pipe (330).
The hot blast of above-mentioned high temperature humidity will contact with cooling water stream pipe (330), dehumidify, and remove moisture.
The moisture of removing from the hot blast of humidity flows down along the inner bottom surface of above-mentioned shell (310), focuses on above-mentioned drip chamber.
The cooling water that flows at cooling water stream pipe (330) also will focus on drip chamber (410).
At this moment, utilize the cooling water and moisture in above-mentioned draining pump (420) the suction drip chamber (410) after, be discharged to the outside.
The hot blast of removing moisture will rely on the driving of Air Blast fan (210) to flow to the side that heater (220) is set with the state of low temperature and low humidity.
Then, the hot blast of above-mentioned low temperature and low humidity becomes the hot blast of high temperature low humidity through heater (220), supplies to again in the cylinder (100).
According to above-mentioned process, carry out the drying course of drying unit.
Therefore as mentioned above, the air of the drying unit of the embodiment of the invention is provided with the water-cooled heat exchanger in (200), can improve the dehumidification rate of the moisture that contains the hot blast of removing the dampness of discharging from cylinder (100).
Drying unit of the present invention has following effect: be provided with the water-cooled heat exchanger in the cylinder of the drying unit of the embodiment of the invention, therefore can improve the dehumidification rate of the moisture that contains the hot blast of removing the dampness of discharging from cylinder, and improve drying performance.
In addition, the cooling water stream pipe of above-mentioned water-cooled heat exchanger is arranged at the oblique line directions that is an angle in air-flow direction, thereby can increase the area that contacts with the hot blast of humidity, improves dehumidification rate.
