The structure of existing magnetic force hydrogenation still is: on the inwall of vertical kettle deflection plate is set, chuck is set on the outer wall, it between the outer wall of chuck and kettle a chamber, magnetic drive device is arranged on the upper end of kettle and both are sealed and matched, link to each other successively with motor with decelerator on the magnetic drive device, under penetrate in the kettle, be on the shaft in the kettle and connect magnetic drive device, the upside of kettle has dog-house, some hydrogenation pipes penetrate in the kettle and the lower end of described hydrogenation pipe extends to downside place (wherein a hydrogenation pipe is discharge nozzle simultaneously) in the kettle through the kettle upside, three layers of agitator are set on the shaft, the upper strata is for pressing down hinged joint disc type turbine stirrer, the middle level is the upper-turn-type turbine stirrer, lower floor's agitator is for pressing down hinged joint disc type turbine stirrer, and shaft is and descends catenary freely.
The use principle of this hydrogenation still is as follows: add catalyst in the kettle, raw material enters in the kettle by delivery pump.Chuck advances steam and heats up to raw material, after waiting to reach uniform temperature, stops to heat up, stir and reach the rotating speed of setting, hydrogen is continously hydrogen adding in kettle by hydrogenation pipe and control valve thereof, carries out hydrogenation, the heat that produces in the reaction is taken away by the cooling water that enters in the chamber.After reaction finishes, stop to stir, carrying out sedimentation, by corresponding that root hydrogenation pipe reactant is pressed into filter then and filters, the clear liquid after the filtration enters crystallization kettle, and contain the filtration dope of tiny catalyst, then return the reaction of carrying out in the kettle next time again.Deflection plate and three layers of agitator acting in conjunction make the gas-liquid-solid three-phase in the kettle seethe down vertically, radially mix.
There is following defective in this magnetic force hydrogenation still: the structural design of lower floor's agitator is unreasonable, its with the catalyst of kettle inner bottom part to around the mixing effect that starts relatively poor, thereby catalytic hydrogenation reaction is produced certain negative effect (as the quality and the speed of influence reaction); The lower end of shaft does not have axially mounting, and during use, the circumferential swing of shaft is bigger, and its circumferential velocity of rotation is subjected to bigger restriction, thereby further catalytic hydrogenation reaction is had a negative impact; Be a chamber only between the outer wall of chuck and kettle, during use, to kettle be rapidly heated, the effect of fast cooling is relatively poor, also can have a negative impact to catalytic hydrogenation reaction.
The utility model content
The technical problems to be solved in the utility model provides a kind of magnetic force hydrogenation still that improves catalytic hydrogenation reaction quality and speed.
For solving the problems of the technologies described above, the utility model provides a kind of magnetic force hydrogenation still, its structure is: on the inwall of vertical kettle deflection plate is set, chuck is set on the outer wall, magnetic drive device is arranged on the upper end of kettle and both are sealed and matched, link to each other successively with motor with decelerator on the magnetic drive device, under penetrate in the kettle, be on the shaft in the kettle and connect magnetic drive device, the upside of kettle has dog-house, some hydrogenation pipes penetrate in the kettle and the lower end of described hydrogenation pipe extends to downside place in the kettle through the kettle upside, three layers of agitator are set on the shaft, the upper strata is for pressing down hinged joint disc type turbine stirrer, the middle level is the upper-turn-type turbine stirrer, and lower floor's agitator is for pressing down hinged joint open-type turbine stirrer.
For can concise description for the purpose of the problem, below this magnetic force hydrogenation still be all abbreviated as this hydrogenation still.
After adopting such structure, the structural design of lower floor's agitator is comparatively reasonable, its with the catalyst of kettle inner bottom part to around the mixing effect that starts better, lower floor's agitator and deflection plate, two-layer agitator acting in conjunction in addition, make the stirring of the gas-liquid-solid three-phase in the kettle more abundant, strengthened reactant all with mix, homogenizing effect is better, thereby catalytic hydrogenation reaction is produced certain positive influences, corresponding quality and the speed that has improved catalytic hydrogenation reaction.
As improvement of the present utility model, hollow sliding sleeve of the lower end spinning of shaft, the column that lower end in the kettle is provided with a coaxial line and play supporting role corresponding to the sliding sleeve place, the inside and outside socket of column and sliding sleeve and both are slidingly matched, and make shaft obtain axially mounting.Like this, during use, the circumferential swing of shaft is less, and circumferentially velocity of rotation is very fast, thereby further catalytic hydrogenation reaction is produced positive influences, further corresponding quality and the speed that has improved catalytic hydrogenation reaction.
As improvement of the present utility model, in the chamber between the outer wall of chuck and kettle helical baffle is set.Like this, during use, to kettle be rapidly heated, the effect of fast cooling is preferable, the heat exchange effect is enhanced, and also can produce positive influences to catalytic hydrogenation reaction, further corresponding quality and the speed that has improved catalytic hydrogenation reaction.
Described kettle adopts the two-layer compound plate structure, and the internal layer of composite plate is that stainless steel material, skin are carbon steel material, and shaft and three layers of agitator are stainless steel material, and chuck is a carbon steel material.Like this, withstand voltage, the decay resistance of kettle effectively improve, and can work well under elevated pressures, and the total volume of kettle is increased, and during use, the output of single this hydrogenation of cover still is big, efficient is high.
