A reaction control method based on microwave heating

Abstract

The invention discloses a reaction control method based on microwave heating. The bottom of a water tank (1) is provided with a microwave heater (3), a microprocessor (2) controls the microwave heater to work to control the temperature of water in the water tank so as to provide an environment temperature for reaction in a reaction vessel (13). The bottom of the water tank is provided with a circulating pump (7) and a pipe (6) in butt joint with an outlet of the circulating pump. The pipe is provided with a plurality of spray pipes (5) at equal intervals. Circulation of water in the water tank is promoted through the circulating pump and the spray pipes. The circulating pump is controlled by the microprocessor. A lifting mechanism (15) based on lead screw transmission is adopted to drive the reaction vessel to ascend and descend. The reaction vessel is internally provided with a stirrer (12). The lifting mechanism based on lead screw transmission is connected with the reaction vessel through a transverse rod. The microprocessor is further connected with a wireless communication unit, and the wireless communication unit is used for communicating with a remote control center. The reaction control method based on microwave heating has an automatic temperature control function, the convection effect is good, the liquid level can be automatically locked, safety is high, and it can be guaranteed that reaction is conducted stably.

Description

technical field [0001] The invention relates to a reaction control method based on microwave heating. Background technique [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 precisely controllable. The existing microwave heating reaction devices cannot accurately control the water temperature and lack active convection. The device relies on natural convection to transfer heat, and the temperature consistency is poor. Furthermore, the existing hot water supply system cannot close the valve in time when the water level is low, which affects the continuous and stable progress of the reaction. Therefore, it is necessary to design a new Reaction control method for microwave heating. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to...
