Abstract
The invention belongs to the technical field experimental instruments, which relates to a multi-functional reaction device used for chemical engineering experiment. The multi-functional chemical engineering experiment device comprises a chemical reaction kettle, a control system and a feeding and discharging and metering system of reaction materials. The chemical reaction kettle adopts a double-layer high-transparent visible kettle body. An upper kettle cover and a lower kettle cover are made of stainless steel materials. The double-layer kettle body adopts conduction oil with high degree of transparency to heat, and the agitation is carried out by adopting strong magnetic force under static sealing. The control system comprises an in-kettle temperature measuring device, a kettle sleeve temperature measuring device, an in-kettle pressure measuring and transmitting device, a motor rotation speed measuring and transmitting device. The control system is connected with a control panel, andcan be connected with a computer to realize remote operation. The feeding and discharging and metering system of reaction materials comprises a feeding and metering system and a backflow separating and metering system of liquid and gaseous reaction materials. The multi-functional chemical engineering experiment device adopts a clasp or bolt connecting structure, wherein clasps and bolts are standardized and general and can be interchanged. The components can be added or cut voluntarily according to the change of the technique. The invention can be applied widely.
Description
technical field [0001] The invention belongs to the technical field of experimental instruments, and relates to a multifunctional reaction device for chemical experiments. technical background [0002] With the development of higher vocational education in our country, the concept of vocational education oriented by work process has been accepted by most people. This requires us to vigorously strengthen the construction of experimental and practical training facilities, and construct a vocational education model that integrates theory and practice. For chemical engineering majors, at present, the instruments and equipment used by people in experiments are not complete, and the connection is relatively complicated. Moreover, most of the instruments are made of glass, and most of the catheters are latex tubes, which are not durable and have poor environmental protection effects. Contents of the invention [0003] The object of the present invention is to provide a multi-fun...
