Detailed description of the invention
A specific embodiment of the invention is described further with reference to the accompanying drawing.
Fig. 1 is the hydrographic chart of present invention curtain coating owner's chilling roller water temperature control system.
Specific embodiment
As shown in fig.1, be a kind of curtain coating owner chilling roller water temperature control system of the invention, including cooling column, water cooling pond,
Refrigerator, temp controlled meter and electric T-shaped valve, the lower section which is arranged in cooling column are after cooling for recycling cooling column
Water, the refrigerator connect the inlet and outlet of main chilling roller by two water channels to constitute interior circulation waterway, water cooling pond connection
There is water pump M3 and water pump M3 exports the water of water cooling pond to refrigerator water inlet and main chilling roller water inlet respectively, refrigerator is extremely
The water pipeline of main chilling roller is provided with water pump M1, and the water return pipeline of main chilling roller to refrigerator is provided with water pump M2, electric T-shaped valve G
Setting is in water return pipeline and its third end water inlet is connected to water pipeline, and the water outlet of electric T-shaped valve also passes through pipeline connection
To cooling column to recycle hot water；The temp controlled meter is connected with the thermocouple L for detecting interior circulation waterway water temperature, and passes through PID closed loop
Control the water temperature of circulation waterway in the job control of electric T-shaped valve.
Specifically, being provided with first manual valve K1 between the water pump M3 and refrigerator water inlet, water pump M3 and master are cold
It is provided with the second manually-operated gate K2 between roller water inlet, is provided with third hand-operated valve between the water pump M1 and refrigerator water outlet
Door K3, is provided with the 4th manually-operated gate K4, the cooling column and electric three passes between water pump M2 and the water outlet of electric T-shaped valve
The 5th manually-operated gate K5 is provided between the water outlet of valve.
The working principle of the invention: (1) summer temperature is higher, and peripheral water temperature is high, so needing to freeze.M1 is opened manually,
M2, M3, refrigerator, cooling column, temp controlled meter.Open first manual valve, three manually-operated gate K3, the 4th manually-operated gate K4.It closes
Second manually-operated gate K2, the 5th manually-operated gate K5.Water route is interior circular flow at this time, sets the cooling temperature of refrigerator and interior
Circulation waterway temperature.Cooling water temperature is needed to be automatically controlled by refrigerator, by temp controlled meter, thermocouple detects the water temperature of interior circulation,
Electric T-shaped valve carries out PID closed-loop control.
(2) winter temperature is lower, and peripheral water temperature is lower.At this moment it does not need to freeze, directly inputs external cold water.
