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

Embodiment 1

[0034] Embodiment 1: as Figure 1-5 As shown in one of them, a high-pressure reaction kettle of the present invention comprises a kettle body 3 and a kettle cover 1, and the kettle cover 1 is connected to the top of the kettle cover 1 by a thread 2, and a magnetic force is connected between the kettle cover 1 and the kettle body 3. The sealing assembly, the kettle body 3 includes an insulation layer 4, a heating layer 5 and an inner container in sequence from the outside to the inside, and the central axis inside the kettle body 3 is connected with a stirring shaft for rotation, and the stirring shaft is placed on the kettle cover 1 The driving system 14 drives the rotation, and the stirring blade 11 is fixed on the stirring shaft. The stirring shaft is an electric heating rod 10 , and the heating layer 5 , the electric heating rod 10 and the driving system 14 are respectively electrically connected to the control panel 19 .

[0035] The control panel 19 has a numeric keypad 9...

Embodiment 2

[0045] Embodiment 2: The structure is basically the same as that of Embodiment 1, the difference is that the stirring shaft in this embodiment is no longer an electric heating rod, that is, it only has a common stirring function. The liner of the kettle body is made of polytetrafluoroethylene material, and has four types of 150ml, 200ml, 250ml, and 300ml. In this embodiment, a 300ml liner is selected to be placed in the center of the reaction kettle, and the pressure inside the kettle body is designed as 8Mpa~12Mpa.

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...
