Embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the internal structure synoptic diagram of the utility model ring spray jet type fermentor tank embodiment, and as shown in the figure, the ring spray jet type fermentor tank of present embodiment comprises tank body 11, and tank body 11 inherent middle positions are provided with stir shaft 12, and stir shaft 12 is provided with a plurality of agitators.Tank body 11 inherent bottom positions are provided with inlet pipe 16, also be provided with ring spray device 14 simultaneously, the ring spray device by the ring main road 141 that communicates with inlet pipe 16 (only demonstrating cross-sectional shape among Fig. 1) and several (for example dozens ofs) the jet tube 142 be installed on the ring main road 141 that distributes forms and this several jet tube 142 jet formation injection flow pattern consistent when fermentor tank stirring fermented liquid with the sense of rotation of agitator.Tuyere by jet tube 142 is set be towards realizing this effect, and for example, the horizontal plane projection of tuyeres that makes all jet tubes 142 is all along the tangential setting of agitator sense of rotation (clockwise).The ring spray jet type fermentor tank of present embodiment sprays the flow pattern ring spray device 14 consistent with the agitator sense of rotation by being provided with in the bottom, not only can eliminate dead angle and blind area that the fermentor tank bottom exists usually, the more important thing is the stirring resistance that can also reduce agitator, thereby reach the purpose of saving energy consumption.
In addition, jet tube 141 structures in the foregoing description as shown in Figure 2, it comprises nozzle 1411 and conduit 1412; Wherein, nozzle 1411 communicates with the ring main road 141 of ring spray device 14; 1412 in conduit envelopes nozzle 1411, and it is long tubular and has trumpet-shaped opening, and the position of the close nozzle in the below of conduit 1412 also is provided with perforate 1413.This design makes from the air of inlet pipe 16, form jet through 141 backs, ring main road by nozzle 1411, and in conduit 1412, form vacuum, and the fermented liquid of jet tube 141 outsides enters the cavity of conduit 1412 from the perforate 1413 of conduit 1412 belows by the effect of negative pressure of vacuum, the gas that gushes out with nozzle 1411 is from the hydraucone ejection of conduit 1412 then, Pen Chu gas is a kind of emulsified state of gas-liquid mixed like this, thereby can reach the effect of breaing up bubble, and then make air to be fully used.
Further, the agitator in the present embodiment ring spray jet type fermentor tank specifically comprises: two axial flow agitators 131 and a runoff agitator 132.Wherein, two axial flow agitators 131 separately are arranged on about mid-way of stir shaft 12, are used to stir fermented liquid and make it mainly produce axial flow; The axial flow agitator 131 that adopts in the present embodiment is shown in the front view and vertical view of Fig. 3 A～3B, its impeller has adopted existing arc shape (not using among the figure) design in the prior art, has very strong axial flow ability, and owing to adopted fairshaped design, can reduce unnecessary resistance, it also has very big shadow area simultaneously, thereby the upwards string that can prevent bubble effectively rises, and then improve the residence time of air in fermented liquid, reach the purpose that improves the dissolved oxygen effect, saves the air use.Continue as shown in Figure 1, runoff agitator 132 approximately is arranged on the terminal position of stir shaft 12, is used to stir fermented liquid and makes it mainly produce radial flow; The runoff agitator 132 that adopts in the present embodiment is shown in the rough schematic of Fig. 4 A～4B, its blade then is to have done improvement on the basis of existing structure, milder parabolic (shown in Fig. 4 A) has been adopted in the cross section, thereby can reduce the resistance of liquid, the bubble that reduces the blade back produces, and also more saves energy consumption compared with traditional form; Need to prove, the projection relation of Fig. 4 A, 4B is not corresponding one by one utterly, the feature part of the two figure runoff agitator that only is used to show that present embodiment adopts herein, those skilled in the art should finely understand the concrete structure that present embodiment adopts the runoff agitator with reference to prior art and feature herein.
Continue as shown in Figure 1, the ring spray jet type fermentor tank of present embodiment also is provided with froth breaking oar 15 in the upper end portion at stir shaft 12 close tank body 11 tops, it is arranged at the top of two axial flow agitators 131, concrete structure then shown in the front view and vertical view of Fig. 5 A～5B, employing be existing froth breaking oar design in the prior art.By the setting of froth breaking oar 15, the further perfect defoaming effect of present embodiment fermentor tank to fermented liquid in the jar.So not only can prevent to stop up various pipelines too much because of foam; and can reduce in the tank body owing to foam too much produces extra pressure; this extra pressure can reduce the inside and outside pressure difference of tank body usually; thereby can offset the air pressure of the gas that enters tank body; and then reduce the tolerance that enters tank body, so set up froth breaking oar 15 in the present embodiment and also can effectively improve stirring efficiency.
At last, the ring spray jet type fermentor tank of present embodiment is in the lower end of stir shaft 12, specifically below axial flow agitator 131 and runoff agitator 132 between also be provided with a plummer-block 17 that is used to support stir shaft 12, the outer rim of plummer-block 17 is fixed on the inwall of tank body 11, thereby make that the rotation of stir shaft 12 each agitators of drive and froth breaking oar is more stable, improved the reliability of total system.
In sum, the fermentor tank of present embodiment forms the injection flow pattern consistent with the agitator sense of rotation by the ring spray device is set in tank body, thereby can reduce the resistance of agitator, reach the purpose of saving energy consumption, can also eliminate the dead angle and the blind area of fermentor tank bottom simultaneously; Jet tube design by nozzle and horn-like opening conduit can make fermented liquid and jet flow stream thorough mixing form emulsified state, thereby play the effect of breaing up bubble; Further, make the fermented liquid of fermentor tank obtain multi-faceted abundant stirring, promoted the effect that stirs fermentation by two axial flow agitators and a runoff agitator are set on stir shaft; The defoaming effect that is provided with fermented liquid perfect by the froth breaking oar and effectively improved stirring efficiency in addition; By being set, plummer-block promoted the reliability that stirs at last.
The utility model also provides a kind of fermentation stirring system of using above-mentioned ring spray jet type fermentor tank, and the embodiment structure comprises motor 21, speed reduction unit 22, shaft coupling 23, mechanical seal 24 and fermentor tank as shown in Figure 6.Wherein, the internal structure and the previous embodiment of fermentor tank are identical, repeat no more herein.12 of stir shafts as for fermentor tank are to connect by the output shaft of shaft coupling 23 with speed reduction unit 22, realize the purpose of power transmission.In addition, whole speed reduction unit 22 is tank body 11 tops that are installed in fermentor tank by flange bottom 25; 24 enclosure interior at speed reduction unit 22 of mechanical seal are arranged between shaft coupling 23 and the flange bottom 25, play the effect of a water-tight.In fact except that fermentor tank itself, being provided with fully of other mechanical parts of fermentation stirring system can be used for reference homogeneous system of the prior art, be not herein but be the fermentor tank of previous embodiment, therefore also no longer given unnecessary details for the fermentation stirring system herein with key of the present utility model.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, those of ordinary skill in the art can expect some identical, replacement schemes apparently, all should fall into the scope of the utility model protection.
