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 drying unit inside; 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 these cylinder 100 discharges; 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 discharges; 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 in 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 inboards.
But, when above-mentioned water pump 320 is arranged at air 200 inboards,, 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; The cooling water and the moisture of above-mentioned drip chamber 410 inside 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 rotations, 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 above-mentioned water-cooled heat exchanger 300 of hot blast process 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 the above-mentioned draining pump 420 suction drip chambers 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, be provided with the water-cooled heat exchanger in the air 200 of the drying unit of the embodiment of the invention, 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: arrange in the cylinder of the drying unit of the embodiment of the invention Therefore the water-cooled heat exchanger is arranged, can improve the hot blast of removing the dampness of discharging from cylinder and contain The dehumidification rate of moisture, and improve drying performance.
In addition, the cooling water stream pipe of above-mentioned water-cooled heat exchanger is arranged in air-flow direction and is one jiao The oblique line directions of degree, thereby can increase the area that contacts with the hot blast of humidity, improve dehumidification rate.
