Description
Technical field
The utility model is related to plastic film production equipment fields, and in particular to a kind of water for adjusting using end temperature
Temperature control system.
Background technology
For plastic film in generating process, forming roller directly affects the quality of production of final film, by forming roller
Control has vital effect in a relatively stable temperature to the consistency of final film quality.And at present on the market
Control system it is more serious for the waste of water resource, water resource cannot be made full use of while extra heat can not be made full use of
Amount.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of energy-saving and can make full use of thermal energy
Water temperature control system.
Technical solution used by the utility model is：A kind of water temperature control system comprising cold water storage cistern, boiler, one
End is connected with cold water storage cistern and inlet pipeline that the other end is connected with using end one end, one end are connected with boiler and
The water return pipeline that the other end is connected with using the end other end and the triple valve for being connected to inlet pipeline and water return pipeline,
Centrifugal pump and heater are installed on the inlet pipeline, temperature detection dress is respectively arranged on inlet pipeline and water return pipeline
It sets.
Temperature-detecting device described in the utility model uses thermocouple, the triple valve to use electronic three-way valve, the temperature
Degree detection device is connect with PLC, while PLC controls triple valve.
The utility model is both provided with pressure gauge on the inlet pipeline and water return pipeline.
The utility model is both provided with butterfly valve on the inlet pipeline and water return pipeline.
The good effect of the utility model is：The utility model increases triple valve between inlet pipeline and water return pipeline,
Water in water return pipeline can enter inlet pipeline, if temperature then needs after heating again less than required temperature value by making
It is adjusted into trip temperature with end, the water in water return pipeline is only when its temperature is unsuitable for being again introduced into the temperature of inlet pipeline
Boiler can be just flowed into, to improve the utilization ratio of water resource, while the water in water return pipeline is also with certain temperature
, it into after inlet pipeline, needs less heat that can be warming up to set point of temperature relative to cool water heating, saves heating energy
Consumption.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In the accompanying drawings, 1- boilers, 2- cold water storage cisterns, 3- inlet pipelines, 4- water return pipelines, 5- triple valves, 6- centrifugal pumps, 7-
Heater, 8- pressure gauges, 9- temperature-detecting devices, 10- butterfly valves.
Specific implementation mode
As shown in Fig. 1, the utility model includes cold water storage cistern 2, boiler 1, inlet pipeline 3, water return pipeline 4 and threeway
One end of valve 5, inlet pipeline 3 is connected with cold water storage cistern 2, and the other end is connected with using the one end at end.One end of water return pipeline 4 with
Boiler is connected, and the other end is connected with using the other end at end, and triple valve 5 is used to be connected to inlet pipeline 3 and water return pipeline 4,
Centrifugal pump 6 is installed on the inlet pipeline 3, having heaters 7 is set on inlet pipeline 3, is provided on inlet pipeline 3
Temperature-detecting device 9.The cold water in cold water storage cistern 2 is extracted out by centrifugal pump 6, carrying out heating to water by the effect of heater 7 rises
Temperature, then flow into use end, by using end after water temperature can be increased, then water from water return pipeline 4 flow into boiler 1 or
Person is flowed back to can inlet pipeline 3.Temperature-detecting device 9 is used to detect the temperature of water in water return pipeline 4, when water temperature meets the requirements,
Water return pipeline 4 is connected to by triple valve 5 with inlet pipeline 3, the flow in water return pipeline 4 back into water lines 3 continue to use hold into
Trip temperature controls.In the present embodiment, the use of end is forming roller.
In order to preferably realize that temperature control, the centrifugal pump 6 are located at triple valve 5 and using between end to entire circuit
On inlet pipeline 3, the heater 7 is located at triple valve 5 and using on the inlet pipeline 3 between end, and temperature-detecting device 9 is located at
On water return pipeline 4 between triple valve 5 and use end.
The temperature-detecting device 9 uses thermocouple, the triple valve 5 to use Electrocontrolled tee valve, the temperature detection dress
It sets 9 to connect with PLC controller, while controlling triple valve 5 and also being connect with PLC controller, when the water that temperature-detecting device 9 detects
When temperature meets sets requirement, water return pipeline 4 is connected to inlet pipeline 3/aperture becomes larger, it realizes recycling for water, works as water temperature
When not meeting the requirement recycled, triple valve 5 becomes smaller inlet pipeline 3 and 4 open circuit of water return pipeline or aperture, water return pipeline 4
Interior water flows into boiler.
It is provided with pressure gauge 8 on the inlet pipeline and water return pipeline 4, for detecting in inlet pipeline 3 and water return pipeline 4
Pressure.
It is provided with butterfly valve 10 on inlet pipeline 3 between centrifugal pump 6 and heater 7, between triple valve 5 and using end
Water return pipeline 4 on setting be again provided with butterfly valve 10.Simultaneously in inlet pipeline 3 on the pipeline of one end of cold water storage cistern 2
Butterfly valve can be set, butterfly valve can also be set on the pipeline of 1 one end of boiler in water return pipeline 4.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
