Abstract
The utility model discloses a solid powder who is applied to wittig reaction can quantitative feeding device comprises the jar body, the discharge gate and the screw feed ware that are used for being connected with reation kettle, and the lower extreme at the agitator is installed to the screw feed ware, is equipped with the stirring rake on the agitator, and a jar top physically is equipped with that nitrogen gas advances tub, outlet duct and sight glass, the utility model has the characteristics of realize solid material's the interpolation of anhydrous anaerobic ration, nitrogen protection, simple structure, convenient operation.
Description
Technical field
The utility model belongs to fine chemistry industry equipment technical field, and especially relating to a kind of pressed powder being applied to wittig reaction can dosing device.
Background technology
Wittig reaction refers to that Wittig reagent and aldehyde ketone are obtained by reacting the important reaction of a class of alkene, and in fine chemistry industry is produced, Wittig reaction requires the reaction condition of anhydrous and oxygen-free, requires quantitative interpolation solid reaction material at a slow speed.For the condition that should ensure anhydrous and oxygen-free; control the solid feeding operation of charging rate again; the general device of the glove box of inert gas shielding or application Schlenk technology that adopts operates at present; these two kinds of method requirements to equipment are higher; operate more complicated; cost is higher, and is only limitted to laboratory use, is difficult to be applied to large-scale industrial production.
Current existing feeding device, the phenomenons such as spring-backed quill is easily corroded by the organic solvent risen, it is swelling to produce, corrosion, cause poorly sealed, complicated structure, charging hopper cannot carry out air displacement before reinforced, and the material in charging hopper leaks in atmosphere cruelly, easy generation deliquescence, can moisture be brought into reaction system, or stick on equipment inner wall, cause being difficult to blanking.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide that a kind of anhydrous and oxygen-free realizing solid material quantitatively adds, the pressed powder being applied to wittig reaction that nitrogen protection, structure are simple, easy to operate can dosing device.
The purpose of this utility model realizes like this, a kind of pressed powder being applied to wittig reaction can dosing device, by tank body, form for the discharging opening that is connected with reactor and screw feeder, be characterized in that screw feeder is arranged on the lower end of agitator, agitator be provided with paddle, the top of tank body is provided with nitrogen inlet, escape pipe and visor.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is the lower end that screw feeder is arranged on agitator, agitator be provided with paddle, the top of tank body is provided with nitrogen inlet, escape pipe and visor, nitrogen is filled with like this by nitrogen inlet, all the time nitrogen protection is connected with in using, achieve the water proof oxygen barrier of solid material preferably, agitator is hand-rail type, charging rate and feeding quantity is regulated by shake speed, agitator is provided with paddle, solid material can be avoided to stick on the inwall of feeder, feeder top cover there is visor, reinforced situation can be observed, the utility model structure is simple, easy to operate, is suitable for promoting.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of pressed powder being applied to wittig reaction can dosing device, with reference to Fig. 1, it is the discharging opening 4 be provided with bottom tank body 8 for being connected with reactor, screw feeder 5 is arranged on the lower end of agitator 2, agitator 2 be provided with paddle 3, the top of tank body 8 is provided with nitrogen inlet 1, escape pipe 7 and visor 6.
