[0028] The usage process of the present utility model is as follows: The operator first adds the fluid to be stirred and reacted through the feed port 2 into the main body 1, then turns on the stirring motor 6 to control the rotation of the stirring blade 8 to stir the fluid. Then, through an external heat exchange pump (not shown in the figure), the heat exchange medium enters the corresponding heat exchange partition 14 through the heat exchange medium inlet pipe 16, the first connecting pipe 17, the first hose 18 and the heat exchange medium inlet 19, and then is discharged through the heat exchange medium outlet 20, the second hose 21, the second connecting pipe 22 and the heat exchange medium outlet pipe 23. Even if the heat exchange partition 14 can well meet the heat exchange requirements of the fluid in the main body 1, the operator can also turn on the electric push rod 11. When the electric push rod 11 operates, it can control the heat exchange partition 14 to move horizontally back and forth between two adjacent stirring blades 8, that is, control the reciprocating movement position of the heat exchange partition 14 in the main body 1, so as to perform heat exchange operations on the fluid at different positions, effectively increasing the contact area between the heat exchange partition 14 and the fluid, and further improving the heat exchange effect on the fluid.
