Valve is provided on pipeline；
One shunting cover plate, the shunting cover plate are located at the lower section of the upper surface of the reaction kettle, lower edge and the reaction
The inner wall of kettle leaves gap；
One circulation baffle, the sky that the circulation baffle plate setting is formed in the inner wall of the shunting cover plate and the reaction kettle
Below gap, and liquid caustic soda is dropped into after the gap flows down on the circulation baffle.
As the preferred of above-mentioned technical proposal, the upper surface of the contour shape and the reaction kettle of the shunting cover plate is mutually fitted
Match somebody with somebody, the gap between the shunting cover plate and the reaction kettle upper surface remains unchanged.
As the preferred of above-mentioned technical proposal, the clearance distance between the shunting cover plate and the reaction kettle upper surface is
0.5 ~ 3 millimeter.
As the preferred of above-mentioned technical proposal, the lower edge of the shunting cover plate is in same level.
As the preferred of above-mentioned technical proposal, the inner edge of the circulation baffle passes through cambered surface with the inner surface of the reaction kettle
It is connected.
As the preferred of above-mentioned technical proposal, nitrogen inlet is provided with above the reaction kettle.
As the preferred of above-mentioned technical proposal, hydrogen evacuated tube, the hydrogen emptying are provided with above the reaction kettle
The inner wall of pipe is provided with polytetrafluorethylecoatings coatings.
As the preferred of above-mentioned technical proposal, the catalyst preparation device is further included there are one agitating device, described to stir
Mixing device includes the stirring rotator being arranged in the stirred tank and the magnetic stirring apparatus being arranged at below the stirred tank.
As the preferred of above-mentioned technical proposal, it is provided with to launch the dispensing port of feed liquid on the reaction kettle.
Circulation baffle enables the lye added in is more scattered to be added in feed liquid first, and reaction is full and uniform, drop
The low dependence to stirring；Then, liquid caustic soda is flowed down along reaction kettle inner wall, and a cleaning is played to the Raney's nickel sputtered on inner wall
Effect prevents the drying of its residue from triggering security risk；Cover plate need to only be shunted can with the matched simple structure of circulation baffle
The double technique effect of enough reactions more fully and safely, while reaction can be carried out continuously, save manual cleaning
Time and human cost.
The utility model compared with prior art, has the following advantages and advantageous effect：
The catalyst preparation device is used for the preparation of Raney's nickel catalyst, and inner wall Raney's nickel can be achieved in preparation process
The self-cleaning of residue, and contacted during liquid caustic soda addition with feed liquid fully, reaction is uniform, and controllability is more preferably.
