A Vertical Polysaccharide High Polymer Mechanical Activation Constant Temperature Solid Phase Reactor

Abstract

The invention discloses a vertical polysaccharide high polymer mechanically activated constant temperature solid-phase reactor, comprising: an outer cylinder body, the inner seal of which is sleeved with a grinding inner cylinder, and the grinding inner cylinder is provided with a stirring device and a plurality of grinding balls, The stirring shaft of the stirring device passes through the cover plate and connects with the driving device; along the outer wall of the grinding inner cylinder, there are multiple annular channels from top to bottom, and the multiple channels form a jacket with the inner wall of the outer cylinder, and the jacket is provided with The working medium inlet and working medium outlet that extend to the outside and communicate with multiple channels are used to pass into the heat exchange working medium to cool or heat the materials in the grinding inner cylinder; the inner wall of the grinding inner cylinder is provided with several cylinders, and the cylinder is equipped with The temperature measuring hole is equipped with a temperature monitoring device; the temperature signal collected by the temperature monitoring device is fed back to the heat exchange device and flow control device for temperature control and circulation of the heat exchange working medium to control the temperature and flow rate of the heat exchange working medium. flow. The reactor makes materials mix evenly, the reaction temperature is stable and easy to monitor, and the quality of the obtained product is high.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a vertical polysaccharide polymer mechanical activation constant temperature solid-phase reactor. Background technique [0002] Solid-phase chemical reaction generally refers to the reaction process in which a chemical reaction occurs between a solid and a solid to form a new solid substance. Since the solid phase reaction does not use a solvent, it has the advantages of simple process, no pollution to the environment, saving solvent, reducing energy consumption and no deflagration, etc. It is an ideal synthesis method. However, in the solid state reaction, the materials are mixed unevenly, which makes the contact between the materials insufficient, and the mass transfer and heat transfer are limited, thereby affecting the reaction effect. For this problem, it can be solved by increasing the reaction temperature. However, for solid materials with low thermal conductivity, this...
