Description
Technical field
The present invention relates to the drying plant technical field, especially relate to the oven dry temperature and humidity control system.
Background technology
In the prior art, some drying units are to utilize hot blast that article are dried, and hot blast produces through the electric heater heating, and its hot blast generation efficient is low, and thermal losses is big, and operating cost is high.
Along with the development of heat pump techniques, adopt the trend of heat pump oven dry paid close attention to by industry, and the appearance of existing part heat pump drying plant, but still there is instability in its Temperature and Humidity Control, and accuracy is not high, makes troubles to actual production.
Summary of the invention
The object of the present invention is to provide a kind of control stabilization, accurate, the heat pump oven dry temperature and humidity control system that is active in one's movements.
For achieving the above object, the present invention adopts following technical scheme:
Heat pump oven dry temperature and humidity controller; Include control panel; Said control panel is provided with preheat starting circuit, temperature survey comparator circuit and moisture measurement comparator circuit; On the temperature survey comparator circuit, be provided with temperature sensor, the temperature survey comparator circuit drives electric heater and heat pump through different enabling signals and stop signal; On the moisture measurement comparator circuit, be provided with humidity sensor; The moisture measurement comparator circuit drives wet exhauster through different enabling signals and stop signal; Preheat starting circuit then selects to drive electric heater and heat pump through clock switch; When wherein preheat starting circuit was worked, the moisture measurement comparator circuit stopped.
The moisture measurement comparator circuit of said control panel comprises the intermittently comparison of upper lower limit value of comparison and humidity of the upper lower limit value of humidity, and humidity is intermittently worked by intermittent pulse signal enabling wet exhauster during lower limit less than humidity.
Heat pump oven dry temperature and humidity controller provided by the invention is provided with preheat starting circuit, temperature survey comparator circuit and moisture measurement comparator circuit, and than management and control, accuracy is high, is active in one's movements through numeric ratio, promotes the effect of heat pump oven dry Temperature and Humidity Control greatly.
Further advantage of the present invention is simple in structure, and is scientific and reasonable, and cost of investment is low, and the operation operation is easy, and Maintenance and Repair are very convenient, improved the operation ratio and the operability of equipment greatly.

Accompanying drawing 1 is control principle figure of the present invention;
Accompanying drawing 2 is a steering logic process flow diagram of the present invention;
Accompanying drawing 3 is an one of which embodiment wiring construction synoptic diagram of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further specified:
Consult Fig. 1,2, shown in 3; Heat pump oven dry temperature and humidity controller provided by the invention; Include control panel 100, said control panel 100 is provided with preheat starting circuit 101, temperature survey comparator circuit 102 and moisture measurement comparator circuit 103, is provided with temperature sensor 200 at temperature survey comparator circuit 102; Temperature survey comparator circuit 102 drives electric heater 400, heat pump 500 through different enabling signals and stop signal; On moisture measurement comparator circuit 103, be provided with humidity sensor 300, moisture measurement comparator circuit 103 drives wet exhauster 600 through different enabling signals and stop signal, and 101 of preheat starting circuits pass through the clock switch device and select to drive electric heater 400 and heat pump 500; When wherein preheat starting circuit was worked, the moisture measurement comparator circuit stopped.The moisture measurement comparator circuit of said control panel 100 comprises the intermittently comparison of upper lower limit value of comparison and humidity of the upper lower limit value of humidity, humidity less than humidity intermittently during lower limit by 600 work of intermittent pulse signal enabling wet exhauster.
During enforcement, control panel 100 gets the work of electric back, sets preheating time; By clock switch device T1 management and control, preheat starting circuit 101 and temperature survey comparator circuit 102 starts, and the temperature that measures when temperature sensor 200 is during greater than heat pump 500 startup values; Select to drive heat pump 500, otherwise drive electric heater 400, effectively energy savings; And reach heating purposes, so that drying work.Crossed or preheating stops when preheating time; Moisture measurement comparator circuit 103 starts; The humidity and the humidity set point that measure through humidity sensor 300 relatively drive wet exhauster 600 work; Wherein humidity set point comprises the upper lower limit value and the humidity upper lower limit value at intermittence of humidity, when humidity measuring then stops wet exhauster 600 work less than the humidity lower limit, when humidity measuring then starts wet exhauster 600 work greater than the humidity higher limit.Start in wet exhauster 600 courses of work, wet exhauster 600 work can be carried out continuous firing and discontinuous operation two-mode, when humidity measuring during greater than humidity higher limit at intermittence, stop the discontinuous operation of wet exhauster 600; And intermittently during lower limit, start the discontinuous operation of wet exhauster 600 less than humidity when humidity measuring; Reach energy saving and emission reduction effects thus.
The present invention is simple in structure, and is scientific and reasonable, and cost of investment is low, and the operation operation is easy, and Maintenance and Repair are very convenient, and than management and control, accuracy is high, is active in one's movements, and has improved the operation ratio and the operability of equipment greatly through numeric ratio.
