Description
Technical field
The utility model belongs to the technical field of plastics-production equipment, is specifically related to a kind of plastic foil chill roll water temperature control device.
Background technology
Partly plastic film is produced or in process, (such as in salivation film production process) needs to use chill roll, chill roll is provided with circulating line, in the course of the work, chill roll implements cooling to plastic foil, the continuous circular flow of cooling water is through chill roll, constantly can heat up at this process cooling water, cooling effect is deteriorated gradually.For this reason, existing chill roll water temperature control system is provided with filling pipe and drainpipe, regularly to be drained the cooling water that a part heated up by drainpipe, the cooling water that another part has heated up retains, replenish a certain proportion of new cooling water (the cooling water mean temperature when temperature of new cooling water works lower than chill roll) simultaneously, the cooling water of new cooling water and reservation, in circulating line mixing, participates in new circulation.But aforesaid way has the following disadvantages: the temperature after the cooling water mixing of 1, new cooling water and reservation is difficult to accurate control, the temperature drift sometimes after mixing, and the temperature sometimes after mixing is on the low side, be not suitable for needing the accurate plastic foil controlled to water temperature; 2, the cooling water of new cooling water and reservation needs certain hour fully to mix, and before abundant mixing, the cooling water temperature in chill roll is unstable.
Utility model content
The purpose of this utility model is overcome above-mentioned shortcoming and provide a kind of plastic foil chill roll water temperature control device, and the water temperature after it can make displacement meets the requirements immediately completely.
Its object can realize by following scheme: a kind of plastic foil chill roll water temperature control device, and include chill roll, the hollow cavity of chill roll is connected with circulating line, and circulating line is serially connected with the circulating pump driving cooling water one-way circulation; Also be provided with cooling tower, be connected with filling pipe between cooling tower and circulating line, filling pipe is provided with the first magnetic valve, and the interface of filling pipe and circulating line is first interface; Circulating line is other is connected to drainpipe, and drainpipe is provided with the second magnetic valve, and the interface of drainpipe and circulating line is the second interface; Its main feature is, filling pipe is also provided with measuring pump; Circulating line is also provided with the 3rd magnetic valve, and described first interface is near the water side of the 3rd magnetic valve, and described second interface is near the water inlet end of the 3rd magnetic valve, and the discharge outlet of described drainpipe is communicated to the water inlet of cooling tower; Circulating line is provided with the temperature detector measuring cooling water temperature; Also be provided with central controller, temperature detector connects central controller, and central controller connects measuring pump, the first magnetic valve, the second magnetic valve, the 3rd magnetic valve respectively.
The utility model has the following advantages and effect:
In utility model works process, the coolant-temperature gage that refrigeration plant in cooling tower makes it store remains the setting operating temperature just equaling cooling water, when in circulating line, the water temperature of cooling water exceedes design temperature, when being not suitable for continuing to implement cooling, can be disposable by the cooling water in whole circulating line, completely, cement out equally, the cooling water making these heat up all changes away in time, whole piece circulating line all supplements new cooling water simultaneously, replacement process is crisp, water temperature after displacement meets the requirements immediately completely, there is not mixing stage or the transition stage of temperature instability.And replaced original cooling water out all reclaims and enters cooling tower, although therefore 100% displacement, waste can not be caused.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of specific embodiment of the present utility model.
Fig. 2 is the effect schematic diagram after the cooling water of structure replacing shown in Fig. 1.
Detailed description of the invention
Shown in Fig. 1, this plastic foil chill roll water temperature control device includes chill roll 1, and the hollow cavity of chill roll 1 is connected with circulating line 2, and circulating line 2 is serially connected with the circulating pump 3 driving cooling water one-way circulation; Also be provided with cooling tower 4, be connected with filling pipe 51 between cooling tower 4 and circulating line 3, filling pipe 51 is provided with the first magnetic valve 61, and filling pipe 51 is first interface 21 with the interface of circulating line 2; Circulating line 2 is other is connected to drainpipe 52, and drainpipe 52 is provided with the second magnetic valve 62, and drainpipe 52 is the second interface 22 with the interface of circulating line 2; Filling pipe 51 is also provided with measuring pump 7; Circulating line 2 is also provided with the 3rd magnetic valve 63, and described first interface 21 is near the water side of the 3rd magnetic valve 63, and described second interface 22 is near the water inlet end of the 3rd magnetic valve 63, and the discharge outlet of described drainpipe 52 is communicated to the water inlet of cooling tower 4; Circulating line 2 is provided with the temperature detector 8 measuring cooling water temperature; Also be provided with central controller, temperature detector 8 connects central controller, and central controller connects measuring pump 7, first magnetic valve 61, second magnetic valve 62, the 3rd magnetic valve 63 respectively.
In above-described embodiment course of work, the coolant-temperature gage that the refrigeration plant in cooling tower 4 makes it store remains the setting operating temperature just equaling cooling water.Normally implement in the process cooled at cooling water, 3rd magnetic valve 63 is opened, and the first magnetic valve 61, second magnetic valve 62 cuts out, circulating pump 3 drives the continuous one-way circulation of the cooling water in circulating line 2 and implements cooling, circulatory flow direction is as shown in the dotted arrow in the middle of pipeline in Fig. 1, and under the driving of circulating pump 3, cooling water constantly enters the 3rd magnetic valve 63 from the water inlet end of the 3rd magnetic valve 63, flow out from the water side of the 3rd magnetic valve 63 again, and flow to chill roll 1; Temperature detector 8 constantly detects the water temperature of cooling water in circulating line 2, when in circulating line 2, the water temperature of cooling water exceedes setting value, centralized controller commands the 3rd magnetic valve 63 cuts out, simultaneously the first magnetic valve 61 is opened, the second magnetic valve 62 opens, and order measuring pump 7 starts, by the storage water in cooling tower 4 quantitatively by the first magnetic valve 61 suction circulating line, original cooling water simultaneously in circulating line 2 is driven away equally, and flows back to cooling tower 4 by the second magnetic valve 62 through drainpipe 52 and recycle.Measuring pump 7 makes the volume of the new cooling water of each suction just equal the volume of whole circulating line 2, so just old cooling water is changed away fully and completely in time, new cooling water completely in circulating line 2 after displacement, new cooling water take up space is as shown in dash area in Fig. 2, ensure that the water temperature in the circulating line 2 after displacement just reaches required operating temperature immediately, replacement process is crisp, there is not the mixing stage, transition stage, after cooling water displacement reaches setting quantity, central controller makes measuring pump 7 cut out, order the 3rd magnetic valve 63 to be opened simultaneously, and the first magnetic valve 61 cuts out, second magnetic valve 62 cuts out, enter new round circulating cooling process.
