Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.Should be understood that, detailed description of the invention described herein only, for description and interpretation the utility model, is not limited to the utility model.

The utility model provides a kind of reactor, this reactor comprises the housing 12 of defined reaction chamber 11, on this housing 12, be provided with material inlet 13 and the material outlet 14 that can be communicated with reaction chamber 11, reactor also comprises the agitator that is positioned at reaction chamber 11, wherein, this agitator comprises and is rotatably installed to the roof of housing 12 and has the sword 24 outstanding along central shaft 21 radial direction to the central shaft 21 of downward-extension and the first mixing part 22 being axially intervally installed along central shaft 21 and 23, the first mixing parts 22, the second mixing part.

By technique scheme, in reactor, be provided with the agitator with the sword 24 outstanding along the radial direction of described central shaft 21, this agitator can promote the graininess reactant in reactant to dissolve rapidly, thereby obtains better mixed effect.

Due to density difference, the not equal reason of fusing point, the reactant being encased in reactor may be difficult for rapid fusion, especially in the time that reactant is solidliquid mixture, with the reactor of the outstanding sword 24 of radial direction, not only can make the fusion of the reactant in different level in reactor, can also accelerate the fusion of the differential responses thing in same level, in the time that reactant is solidliquid mixture, effect is more obvious.Now taking reactant as solidliquid mixture as example describes, as shown in Figure 1, in the time of this reactor work, can rotary middle spindle 21, be arranged on this central shaft 21 and also following this central shaft 21 along the outstanding sword 24 of these central shaft 21 radial direction and together rotating, solid particle during through sword 24 surperficial, is smashed by the sharp-pointed portion of this sword 24, thereby make the volume of solid particle less, also just improved the dissolution velocity of this solid particle in liquid reactants.

This sword 24 has various structures form, and preferably, as shown in Figure 1, the first mixing part 22 comprises and being fixedly installed on central shaft 21 and outstanding multiple needle-like pieces radially, and the tip of the plurality of needle-like piece forms sword 24.This sword 24 can be arranged on the outer peripheral face of this central shaft 21, also can be arranged on other members, then this member with sword 24 is fixed on this central shaft 21, as depicted in figs. 1 and 2.

No matter needle-like piece is directly arranged in the periphery of central shaft 21, still be arranged on member, this needle-like piece can arrange angle along the circumferential arrangement of described central shaft 21, preferably, as shown in Figure 2, needle-like piece is 180 degree to 360 degree along the angle a of the circumferential distribution of central shaft 21.

Sword 24 can also be selected other version, and preferably, as shown in Figure 3, sword 24 is annular; Or sword 24 is formed as annular sawtooth portion.

Relative position relation between the first mixing part 22 and the second mixing part 23, can be according to reactant flexible design different in reactor, when in reactant exist solid particle and this solid particle relatively to concentrate on the top of reaction chamber time, the first mixing part 22 can be arranged at and the corresponding position of this solid particle.Preferably, as shown in Figure 1, the first mixing part 22 is positioned at the top of the second mixing part 23.

Different version can be selected according to the different demands of reactant in the second mixing part 23, and preferably, as shown in Figure 1, the second mixing part 23 comprises the many stirring rod that are fixed on central shaft 21 and radially extend.The second mixing part 23 of this form is simple in structure and cheap for manufacturing cost, therefore has good application prospect.

For the reactant of different aspects in reactor is mixed fully, preferably, the second mixing part 23 comprises the helical blade being arranged on central shaft 21 outer peripheral faces.

For the reactant of the different aspects in further augmenting response still fully mixes, preferably, as shown in Figure 4, helical blade comprises the first spire 31 and the second spire 32, and the rotation direction of this first spire 31 and the second spire 32 is contrary.The first spire 31 and the second spire 32 that this rotation direction is contrary advance reactant to move along contrary direction, thereby in reactor, form motion stream, to promote the further mixing of reactant.

Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.

It should be noted that in addition, each concrete technical characterictic described in above-mentioned detailed description of the invention, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible combinations.

In addition, between various embodiment of the present utility model, also can be combined, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
