Description

A kind of mixing reactor

Technical field

The utility model relates to a kind of reactor, relates in particular to a kind of mixing reactor, belongs to chemical industry equipment field.

Background technology

Reactor is a kind of important chemical industry equipment, and its Main Function is to store or supply corresponding chemical substance reaction.Reactor is the plant equipment that is applicable at present numerous areas, reactor is multifunctional integrated device, stirring is wherein one of major function of reactor, and the stirring intensity of reactor directly has influence on the reaction result of material, and the quality of final products is played to vital effect.Existing reactor is generally a blade-carrying axle and rotates in tank body, plurality of raw materials is uniformly mixed, the inner tank wall that fails to be convened for lack of a quorum the liquid that existing agitating mode produces flows with layer flow mode, without shear action, mixed effect is bad, need higher rotating speed and longer time just can reach required mixed uniformly effect, reduced production efficiency.

How to design a kind of reactor and can make the solution near chamber wall in kettle be mixed equably, thereby Reaction time shorten falls and can save consumption, is those skilled in the art's guardian technique problems urgently to be resolved hurrily.

Utility model content

The utility model, for deficiency, provides a kind of mixing reactor of evenly mixed reactant, make the material in reactor mix fully, completely and to react, thereby Reaction time shorten falls and can save consumption.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of mixing reactor, comprise reactor body, main agitator, and auxiliary agitator; Described main agitator is located at the top of reactor chamber body, the shaft that comprises motor, is connected with described motor-driven, and be located at the paddle on described shaft; Described auxiliary agitator is positioned at described reactor body bottom, near the sidewall of described reactor; Described auxiliary agitator comprises rotating shaft, dwang, passive paddle, and two blades; Described rotating shaft is positioned at the bottom of described reactor body; One end of described dwang horizontally rotates and is connected with described rotating shaft, and its other end is provided with two blades; Described two blades become V-shape, and the angle between two blades is 60 ~ 120 °; Described passive paddle is positioned on described dwang, near the bottom of described dwang.

On the basis of technique scheme, the utility model can also do following improvement.

Further, in described reactor body, the quantity of auxiliary agitator is two to six.

Further, in described reactor body, the quantity of auxiliary agitator is three, and equidistantly distributes between these three auxiliary agitators.

Further, the length of the described shaft of main agitator is more than or equal to the half of the reactor body degree of depth; The total height of described auxiliary agitator is less than or equal to the half of the described reactor body degree of depth.

Further, described main agitator and described auxiliary agitator exist and partly overlap in the horizontal direction.

Further, described two blades are in same plane, and this plane is vertical with horizontal plane.

In the utility model, between the described paddle of main agitator and the described blade of auxiliary agitator and passive paddle, do not contact.

The beneficial effects of the utility model are: compared with prior art, mixed type reactor of the present utility model is due to the existence of auxiliary agitator, can be by the stirring of main agitator, in the situation that not needing motor or consuming the energy, carry out passive stirring, make the solution in kettle corner also produce axial flow.Its action principle is: the liquid in rotation that main agitator rotarily drives in reactor flows, the blade of auxiliary agitator carries out passive rotation under the drive of fluid vortex, and then drive is positioned at the rotation of the passive paddle on dwang equally, the liquid in reactor corner is also flowed, be conducive to the abundant mixing of solution in whole reactor.Thereby both shortened the reaction time of reactant, reduced energy consumption, and further made again solution evenly mix.
