Problems solved by technology

[0002] Many reactions are required to be carried out in a constant temperature environment, or the reaction is required to be carried out according to a predetermined temperature curve, which requires that the temperature of the environment must be accurately and controllable. The existing microwave heating reaction device cannot accurately control the water temperature, and lacks active convection The device relies on natural convection to transfer heat, and the temperature consistency is poor. Moreover, the existing hot water supply system cannot close the valve in time when the water level is low, which affects the continuous and stable reaction. Therefore, it is necessary to design a new multi- Functional Microwave Heating Reaction Control System

Abstract

The invention discloses a multifunctional microwave heating reaction control system which comprises a water tank (1), a microwave heater (3), a micro processor (2) and a water tank bottom shell, wherein a magnetron tube for heating is arranged in the microwave heater; a heating cavity (4) of the microwave heater extends into the water tank from a base plate of the water tank; a layer of shielding mesh capable of penetrating through liquid covers the heating cavity; the micro processor (2) controls water temperature in the water tank by controlling the operation of the microwave heater; a circulating pump (7) and a pipeline (6) butted with an outlet of the circulating pump are arranged at the bottom of the water tank. The multifunctional microwave heating reaction control system further comprises a lifting mechanism (15) based on screw rod transmission. By adoption of a closed-loop PID control system, the temperature can be precisely controlled. The multifunctional microwave heating reaction control system has an automatic temperature control function, is excellent in convection effect, high in safety and high in integration degree and can automatically lock a liquid level and ensure that the reaction can be stably carried out.
