Description
Technical field
The utility model belongs to automation field, relates in particular to a kind of vacuum conditioner recirculated cooling water temperature detection and control device.
Background technology
Tobacco leaf is when vacuum conditioning, and vacuum conditioner first will if the excess Temperature of water in its circulating cooling system can cause the steam-jet vacuum pump ability to work to descend, extend evacuated time to finding time in casing, even can cause the machine operation of can't finding time.And the cooling water water temperature is higher, and the quantity of steam that consumes during the tobacco moisture regain is more, not only causes on the energy and wastes, and also can affect the quality of tobacco leaf conditioning.
Existing vacuum conditioner circulating cooling system does not have temperature-detecting device, in case the long problem of evacuated time appears in vacuum conditioner, the maintenance personal can't determine it is that coolant water temperature is too high and or machine part damages when searching reason.This is slowing down the maintenance progress virtually, causes the reduction of production efficiency.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can in real time, automatically detects and control the device of vacuum conditioner circulating cooling coolant-temperature gage.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Vacuum conditioner recirculated cooling water temperature detection and control device, comprise that cooling tower reaches and its cooling water collecting tank that is connected by pipeline, be provided with temperature sensor on the cooling water collecting tank, the output of temperature sensor is connected with the input of a PLC control system, and the output of PLC control system is connected with the input of the frequency converter of cooling blower; Cooling blower is positioned at above cooling tower, is connected with the output of above-mentioned frequency converter.The vacuum conditioner cooling water flows into from the cooling water collecting tank in the condenser of vacuum conditioner, after participating in supercooling work, flows into cooling tower, is flowing into the cooling water collecting tank through after cooling blower cooling by pipeline.Water temperature in the cooling water collecting tank is by the temperature sensor Real-Time Monitoring.In the PLC control system, PLC regulates the rotating speed of cooling blower according to the height of water temperature to temperature sensor by regulating the cooling blower frequency converter with the water temperature transfer of data that collects, the water in cooling tower is carried out acceleration or deceleration cooling.Make the temperature of water in cooling tower satisfy the requirement of production technology; Simultaneously also reasonably control the energy consumption of blower fan, saved the energy.Simplicity of design has avoided causing because coolant water temperature is too high the situation of the moisture regain Efficiency Decreasing of vacuum conditioner, has improved production efficiency.When the vacuum conditioner evacuated time is long, during inefficiency, the maintenance personal can judge whether it is because the reason of water temperature over-high by the procuratorial work temperature data.If not this factor, the maintenance personal can fast detecting other parts, reduced maintenance time, improved production efficiency.
Described vacuum conditioner recirculated cooling water temperature detection and control device, the output of PLC control system also are connected with the input of moisturizing magnetic valve simultaneously; Described moisturizing magnetic valve is arranged on the pipeline that connects cooling water collecting tank and cold water source.Sometimes, weather is extremely hot, even the cooling blower full speed running, the water temperature in cooling tower also can't satisfy the requirement of production technology, and the moisturizing magnetic valve that this moment, the PLC control system can be controlled on the pipeline that is arranged on connection cooling water collecting tank and cold water source is opened.Annotate from the cold water of cold water source in the cooling water collecting tank, the water in the cooling water collecting tank flows in the condenser of vacuum conditioner again, guarantees that the cooling water temperature that participates in cool cycles satisfies Production requirement.
The utility model compared with prior art has following advantage: simplicity of design, and easy to operate, under the prerequisite that satisfies the production technology demand, saved energy consumption, improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, vacuum conditioner has condenser 1, and the delivery port of condenser 1 is connected by pipeline with cooling tower 2, and cooling tower 2 is connected with cooling water collecting tank 5 by pipeline.Cooling tower 2 tops are provided with cooling blower 3, and cooling blower 3 is connected with the output of frequency converter 4, and PLC control system 7 outputs are connected with the input of the frequency converter 4 of cooling blower 3.Cooling water collecting tank 5 is provided with temperature sensor 6, and the output of temperature sensor 6 is connected with the input of PLC control system 7.The output of PLC control system 7 also is connected with the input of moisturizing magnetic valve 8 simultaneously, and moisturizing magnetic valve 8 is arranged on the pipeline 9 that connects cooling water collecting tank 5 and cold water source, and cooling water collecting tank 5 is connected by pipeline with cooling tower 2.
during work, cooling water becomes warm water and enters cooling tower 2 after vacuum conditioner condenser 1, through after cooling blower 3 cooling, flow in cooling water collecting tank 5, in cooling water collecting tank 5, water temperature is by temperature sensor 6 Real-Time Monitorings, temperature sensor 6 with the water temperature transfer of data that collects in PLC control system 7, PLC control system 7 is according to the height of water temperature, regulate cooling blower 3 rotating speeds by the frequency converter 4 of regulating cooling blower 3, the warm water that enters cooling tower 2 is carried out acceleration or deceleration cooling, cooled water flows in cooling water collecting tank 5, make the temperature of water in cooling water collecting tank 5 satisfy the requirement of production technology, activity in production that can the sustainable participation cool cycles.If temperature is higher, even cooling blower 3 oeprations at full load, when cooling water temperature also can't satisfy manufacturing technique requirent, PLC control system 7 is controlled moisturizing magnetic valve 8 and is opened, to the cold water of the interior filling of cooling water collecting tank 5 from cold water source 9, guarantee that the cooling water temperature that participates in cool cycles satisfies Production requirement.
