High-pressure reaction kettle

Abstract

The invention discloses a high-pressure reaction kettle which comprises a kettle body and a kettle cover, the kettle cover is connected to the top of the kettle cover, a magnetic sealing assembly is connected between the kettle cover and the kettle body, the kettle body sequentially comprises a heat preservation layer, a heating layer and an inner container from outside to inside, and a stirring shaft is rotatably connected to the central axis in the kettle body. The stirring shaft is driven to rotate by a driving system arranged on the kettle cover, stirring blades are fixed on the stirring shaft, the stirring shaft is an electric heating rod, and the heating layer, the electric heating rod and the driving system are respectively and electrically connected to a control panel. The stirringefficiency and the kettle body sealing performance can be considered at the same time, the integration of temperature measurement and a control device is realized, the heat transfer efficiency in thereaction kettle is enhanced, the reaction efficiency and the experiment safety are further improved, and the innovative significance is realized.

Description

technical field [0001] The preparation technology of the invention belongs to the technical field of chemical equipment, and in particular relates to a high-pressure reaction kettle. Background technique [0002] High pressure reactor is a commonly used device for high temperature and high pressure, especially for flammable, explosive and toxic chemical substances. It ensures safe use under production and experimental conditions, and is widely used in laboratories and factories. Under the condition of high temperature and high pressure reaction, due to the failure of temperature and pressure control, the volume expansion and other factors will cause the pressure in the reaction kettle to increase, and there will be safety hazards such as explosion. Therefore, it is necessary to set up temperature and pressure display and control devices for high-pressure reactors to eliminate potential safety hazards. At the same time, in order to fully mix the materials and speed up the re...

Problems solved by technology

But this invention also has certain problems: the traditional mechanical seal method is adopted in the design of the coupling, which cannot solve the wear problem in the design of the agitator, so it cannot take into account the sealing and stirring efficiency. On the other hand, This invention only designed a temperature measurement system but lacked a perfect temperature control system. This problem is common in existing high-pressure reactors for experiments. Most of the high-pressure reactors with perfect temperature control systems are relatively large-scale intelligent reactions for chemical industry. kettle
