Abstract
The utility model discloses a stepless microwave power regulation and control device of a vacuum drier. The stepless microwave power regulation and control device comprises a control signal input device, a temperature sensor, a programmable logic controller (PLC), a power regulator, a high-voltage transformer, a magnetron and a filament transformer, wherein the control signal input device is connected with the PLC which is connected with the power regulator and the temperature sensor; controllable analog signals are calculated by the PLC according to present temperature data from the temperature sensor and temperature data from the control signal input device, and then, the controllable analog signals are output to the power regulator by the PLC; the power regulator calculates voltage according to the analog signals and then outputs the voltage to the high-voltage transformer, and the voltage is multiplied and rectified by the high voltage transformer and then is output to the magnetron; and one end of the filament transformer is connected to a mains supply, and the other end of the filament transformer is connected with the magnetron and provides constant voltage and current to the magnetron which is kept in a standby state. The stepless microwave power regulation and control device of the vacuum drier can accurately control the microwave power of the vacuum dryer, and further, can accurately control the drying process of materials, thereby enhancing a drying effect.
Description
Technical field
The utility model relates to a kind of microwave power stepless regulation and control device of vacuum drier.
Background technology
The microwave power operated by rotary motion particular gears of traditional microwave vacuum drier can only be regulated according to gear during regulation and control, therefore can't accomplish accurate control, has influenced drying effect.
Summary of the invention
The utility model technical problem to be solved provides a kind of microwave power stepless regulation and control device that can accurately control the vacuum drier of the microwave power in the vacuum drier.
For this reason; The microwave power stepless regulation and control device of the vacuum drier that the utility model provides; Comprise control signal input unit, temperature sensor, PLC, electric power adjuster, high-tension transformer, magnetron and filament transformer; Said control signal input unit connects PLC, and PLC connects electric power adjuster and temperature sensor, said PLC according to from the Current Temperatures data of temperature sensor and from the temperature data of control signal input unit calculate and output controllable simulation signal to the electric power adjuster; The electric power adjuster calculate according to analog signal and output voltage to high-tension transformer; To magnetron, the said filament transformer one end connection civil power other end is connected with magnetron and for magnetron provides constant electric current and voltage, makes magnetron be in holding state through high-tension transformer voltage multiplying rectifier output high pressure.
In the microwave power stepless regulation and control device of the vacuum drier that the utility model provides; PLC can according to from the Current Temperatures data of temperature sensor and from the temperature data of control signal input unit calculate and output controllable simulation signal to the electric power adjuster; The electric power adjuster calculate according to analog signal and output voltage to high-tension transformer; Export high pressure to magnetron through the high-tension transformer voltage multiplying rectifier; The microwave power of accuracy controlling output thus, thus the dry process of material accurately controlled, strengthen drying effect.
Description of drawings
The circuit block diagram of the microwave power stepless regulation and control device of the vacuum drier that provides for the utility model among the figure.
The specific embodiment
As shown in the figure, the microwave power stepless regulation and control device of the vacuum drier that the utility model provides comprises control signal input unit, temperature sensor, PLC, electric power adjuster, high-tension transformer, magnetron and filament transformer; Said control signal input unit connects PLC, and the control signal input unit is a touch-screen in the present embodiment, and touch-screen and PLC carry out bi-directional data and transmit; The data that PLC calculates can return to touch-screen and show, PLC connects electric power adjuster and temperature sensor, said PLC according to from the Current Temperatures data of temperature sensor and from the temperature data of control signal input unit calculate and output controllable simulation signal to the electric power adjuster; The electric power adjuster calculate according to analog signal and output voltage to high-tension transformer; To magnetron, the said filament transformer one end connection civil power other end is connected with magnetron and for magnetron provides constant electric current and voltage, makes magnetron be in holding state through high-tension transformer voltage multiplying rectifier output high pressure; In a single day having this moment high pressure to trigger is exportable microwave power; The size of microwave power confirms that by the drying medium current temperature value temperature is high more, and microwave power output is more little; Otherwise, big more.
