Microwave-assisted agitating ball-milling reactor

Abstract

The invention provides a microwave assisted agitating ball-milling reactor. The reactor comprises a ball-milling system, a microwave-assisted system and a control system, wherein the ball-milling system includes a driving motor, a stirring rod, a stirring paddle, a ball-milling cylinder, and a milling ball placed in the ball-milling cylinder; the microwave-assisted system comprises a microwave heating cylinder, a thermal insulation wave-transparent layer, a microwave feeding port, a microwave emission source, and a microwave power source; the ball-milling cylinder is placed in the microwave heating cylinder; a layer of the thermal insulation wave-transparent layer is wrapped in the inner surface, along the circumference, of the sidewall of the microwave heating cylinder; the upper end of the stirring rod penetrates through the microwave cylinder the top wall of the ball-milling cylinder and is connected with the driving motor; the bottom end of the stirring rod extends in the ball-milling cylinder; the stirring paddle is arranged at the portion, in the ball-milling cylinder, of the stirring rod; the microwave feeding port is arranged on the sidewall of the microwave heating cylinder, and sealed and fixedly connected with the inner cavity of the microwave heating cylinder; and the microwave power source is connected with the control system. According to the reactor, the solid phase involved reaction can be more complete and uniform under the premise of achieving more precise control of the temperature.

Description

technical field [0001] The invention relates to the technical fields of chemical engineering technology, chemical reaction engineering and powder material preparation, in particular to a stirring ball milling reactor, in particular to a microwave-assisted stirring ball milling reactor. The microwave-assisted stirred ball milling reactor is suitable for all reactions involving solid phases, such as solid-liquid reactions, gas-solid reactions, and solid-solid reactions, etc., and is also suitable for high-quality powder material preparation and special chemical reaction engineering. Background technique [0002] Stirring ball mill is a kind of mechanical processing equipment that is often used for crushing or dispersing solids in liquid phase, and is widely used in industries such as biology, food, cosmetics, medicine, ceramics, materials and pesticides. In the stirring ball mill, there is a stirring shaft connected to the driving device, and the grinding balls filled in the g...
