And multiple moving blades 223 are connect with agitating shaft 222.In order to reduce 214 space of inner cavity of the occupancy of rabbling mechanism 220, setting
When setting rabbling mechanism 220, the multiple moving blades 223 for playing stirring action are respectively positioned in autoclave body 210, and are used to drive agitating shaft
222 and the power device 221 that is rotated in the inner cavity of autoclave body 210 214 of moving blade 223 can then be located at outside autoclave body 210, and set
Setting the power device 221 outside autoclave body 210 can connect with the first lid 212, in order to the installation of the reaction kettle 200, and
When agitating shaft 222 is arranged, to enable the power device 221 being located at outside autoclave body 210 to drive in 210 inner cavity 214 of autoclave body
Agitating shaft 222 and moving blade 223 rotate, therefore agitating shaft 222 pass through the first lid 212 after protruding into inner cavity 214, that is, be located at
The agitating shaft that 222 part of agitating shaft and power device 221 outside autoclave body 210 are sequentially connected, and are located in 210 inner cavity 214 of autoclave body
222 parts are connect with moving blade 223.
When moving blade 223 is arranged, to improve the effect stirred, so that material mixing is more uniformly, therefore multiple rotations
Blade 223 is successively spaced setting along the axis direction of autoclave body 210, and can be parallel to each other between adjacent moving blade 223.Its
It is secondary, to further increase the mixing uniformity after stirring, therefore multiple barrier plates are additionally provided on the side wall of reaction kettle 200
218, multiple barrier plates 218 are successively spaced setting along the axis direction of autoclave body 210.It should be noted that prevent moving blade
223 generate interference with the barrier plate 218 on the side wall of reaction kettle 200 in the course of rotation, therefore when barrier plate 218 is arranged,
It is required that barrier plate 218 is located at outside the pivot region of adjacent moving blade 223.And when moving blade 223 and agitating shaft 222
Axis it is vertical when, i.e., when the slewing area of moving blade 223 is vertical with the axis of agitating shaft 222, barrier plate 218 with it is adjacent
Moving blade 223 be spaced on the axis direction of autoclave body 210.
Referring to figure 2. and Fig. 3, the material in inner cavity 214 is during reaction, for convenient for controlling 210 inner cavity 214 of autoclave body
In temperature, therefore need to be monitored the temperature in inner cavity 214, and need to need when its temperature impacts reaction pair
Its temperature is controlled, therefore cooling structure 240 is additionally provided on the side wall of autoclave body 210.
Specifically, being additionally provided with multiple temperature-measuring ports on the side wall of reaction kettle 200 for the temperature in monitoring inner cavity 214
219, multiple temperature-measuring ports 219 along autoclave body 210 axis direction successively arranged for interval, thus at least formed middle part temperature-measuring port 219 and
Bottom temperature-measuring port 219.
Secondly, cooling structure 240 includes the coolant liquid cavity 241 that is arranged on 211 wall of cylinder, and with coolant liquid cavity
The cooling liquid inlet 242 and cooling liquid outlet 243 of 241 connections.To form coolant liquid cavity 241 on 211 wall of cylinder, therefore can be with
Collet is arranged in the side wall of cylinder 211, i.e., the inner wall of cylinder 211 is provided with the hollow coolant liquid for accommodating coolant liquid and holds
Chamber 241.
