Background technology
Be that a plurality of magnetron pack (being a group with three magnetrons generally) are provided with power control and regulation class by group in existing big-and-middle-sized (power is greater than 1.5kW) microwave heating equipment.As the general power of selling on the market is that the microwave dryer of certain model of 6kW is an example, has only 2kW, 4kW, three power control and regulation of 6kW class.Hop interval is too big between each class, is not easy to effectively control and adjusting, also is unfavorable for realizing the coupling of microwave output power and (heating) drying process.If microwave output power is too small, be lower than the needed level of (heating) drying process, on the one hand equipment can not be played one's part to the full, cause the equipment waste, can cause dry mass problems such as the reduction of (heating) rate of drying prolongs (heating) drying time, (heating) dry deficiency on the other hand.If microwave output power is excessive, surpass the needs of (heating) drying process, cause energy dissipation on the one hand, also caused (heating) dry mass problems such as (heating) dry, burnt paste on the other hand, microwave energy can not be utilized effectively.Because ever-changing by the character of (heating) dried material, (heating) dry load also is not quite similar under the different condition,, just be unfavorable for realizing the coupling of microwave output power and drying process if can not realize control and regulation effectively to microwave output power.
Summary of the invention
At the problems referred to above, task of the present invention provides a kind of microwave-heating drier of adjustable power, make the dry power output of microwave (heating) effectively control and to regulate according to the variation of the quilt character of (heating) dried material and (heating) drying load, improve the quality of products and drying efficiency to reach, reach purpose of energy saving thereby also improve energy utilization efficiency indirectly.
For realizing above-mentioned task, technical scheme of the present invention is: a kind of microwave-heating drier of adjustable power, at least two microwave raddiating circuit unit are installed in the drying machine, each microwave raddiating circuit unit is by a contactor, a high-tension transformer and one group of corresponding three magnetron constitute, three input coils of high-tension transformer and the corresponding connection of three outputs of contactor, above-mentioned three magnetrons of corresponding connection on three output windings of high-tension transformer, in each microwave raddiating circuit unit, has the power controller circuit that is connected with intermittent power supply on the solenoid of contactor of one road microwave raddiating circuit unit at least.
Each power of organizing magnetron equates.
The power controller circuit is made of the auxiliary reclay that square wave generation circuit and output thereof connect, and the contact of auxiliary reclay is serially connected on the power supply line of solenoid of contactor, and the dutycycle of square wave generation circuit is adjustable continuously.
The square-wave cycle of square wave generation circuit is at 20-30 between second.
Each is organized magnetron and evenly distributes in hothouse, and each magnetron of respectively organizing magnetron is in staggered distribution each other.
Because in each microwave raddiating circuit unit, has the power regulating switch circuit that is connected with intermittent power supply on the solenoid of contactor of one road microwave raddiating circuit unit at least, can effectively improve the reasonable coupling between microwave output power and load, improve the dry quality of energy utilization ratio and (heating); Be convenient to the control of realization simultaneously, the reasonable operation that is beneficial to process different types of material and under different disposal amount situation, makes microwave (heating) drying machine to (heating) dry general power.
