The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 2, the agitator arm 2 of the present embodiment comprises three blades 21 and a wheel hub 22, is welded with three braces 221 on this wheel hub, and those blades 21 are fixedly connected with this wheel hub 22 by those braces 221.Those blades 21 are threaded with those braces 221.Evenly be provided with reinforcement 222 on those braces 221, be provided with a keyway 223 on the axis hole of this wheel hub 22.Each blade 21 includes an aerofoil section 211 and one first fin section 212.It is to be noted that the width of the first flanging 2121 of this first fin section 212 accounts for 1/2 of this blade width, the length of second flanging 2122 of this first fin section 212 accounts for 1/2 ~ 4/5 the best of this blade length.
As shown in Figure 3, this wheel hub 22 is fixedly connected with a rotating shaft 23 by this keyway 223, in order to form the agitator of the present embodiment.Be mutually angle δ between adjacent two braces 221, the span of angle δ is 25 ° to 40 °.This aerofoil section 211 and this first fin section 212 are mutually angle γ, and the span of angle γ is 160 ° to 175 °.
The concrete mounting structure of the agitator of the present embodiment as shown in Figure 4, namely the wheel hub 22 of agitator arm 2 is fixedly connected with this rotating shaft 23 by a connecting key 224, and uses sealing plate 225 and screw 226 to carry out consolidation process.
By those blades being bent into the version that comprises this aerofoil section 211 and this first fin section 212, the radially discharge capacity of this agitator (along the discharge capacity radially of blade) and axial discharge capacity (along the axial discharge capacity of blade) increase severely simultaneously.
As shown in Figure 5, the anaerobic fermentation tank 3 of the present embodiment comprises a tank body 31, a plurality of agitator as above and a liquid-blocking device 36.This tank body 31 has an axis 32.Each agitator is fixedly connected with by the join domain of its rotating shaft 23 with the internal face of this tank body 31.This liquid-blocking device 36 comprises at least one slope, and those slopes are used for stopping that also reflection shot is to its fluid.
As shown in Figure 5, the axis of each rotating shaft 23 forms first projection line 231 that is projected as in the plane at the normal 33 of its join domain and this axis 32.This first projection line 231 is α with the angle of this normal 33, and the α span is 20 ° to 70 °, so this rotating shaft 23 has along the axial inclination of columniform tank body, i.e. axioversion.Because rotating shaft 23 has axioversion, during use, this fluid wave 34 has the shunting 35 that has a down dip discharged to this liquid-blocking device 36, the rear formation downslide of this liquid-blocking device 36 shunting 37 and convolution shunting 38 are being clashed in this shunting 35 that has a down dip, and then impel zymotic fluid to form along the axial tumble mixed of tank body, realize that finally uniform stirring and the raw material of this anaerobic fermentation tank 3 bottoms do not deposit.
As shown in Figure 6, the axis of each rotating shaft 23 is at the normal 33 of crossing its join domain and perpendicular to second projection line 232 that is projected as in the plane of this axis 32.This second projection line 232 is β with the angle of this normal 33, and the β span is also 20 ° to 70 °, so this rotating shaft 23 has along tank body inclination radially, i.e. radial skew.Because rotating shaft 23 has radial skew, during use, those agitators are except carrying out individually local Stirring to zymotic fluid, also has local vortex shunting 350, those local vortex shunting 350 actings in conjunction, drive zymotic fluid around the whole eddying motion of axis 32 of tank body, therefore form zymotic fluid along tank body tumble mixed radially, after zymotic fluid process tank body tumble mixed radially, the uniformity has obtained improving further.
In summary, in order to carry out the overall mixing in anaerobic fermentation tank, not only used the mode at two dimension oblique cutting agitators, namely along anaerobic fermentation tank axially and radially all tilt, also improved the structure of agitator arm and used liquid-blocking device.In addition, original bubble floats and the liquid-circulating of anaerobic fermentation tank between inside and outside in combining with fermentation liquid, and the anaerobic fermentation tank of the present embodiment not only can make culture medium and thalline be mixed fully, can also reduce widely energy consumption.
From energy consumption, in the situation that the equal discharge opeing ability that stirs, the stirring Energy Intensity Reduction of the anaerobic fermentation tank of the present embodiment is to 44kw, and the volume of anaerobic fermentation tank is 3500m
3, namely the well-mixed operation energy consumption of zymotic fluid is only 0.012kw/m
3(44kw/3500m3), so the unit volume power of agitator is extremely low, i.e. discharge opeing efficient is higher.
As shown in Figure 7, in the anaerobic fermentation tank of the present embodiment, paraboloidal form that this liquid-blocking device 36 can also adopt that Open Side Down, this moment, the bottom of liquid-blocking device 36 needed supporting rod 39, and supporting rod can use commercially available I-steel.
As shown in Figure 8, have the many places same section with the agitator arm 20 of the present embodiment and the agitator arm 2 of embodiment 1, for example comprise an aerofoil section 2011 and one first fin section 2012, these same sections repeat no more.The difference of the present embodiment and embodiment 1 is: each blade also includes one second fin section 2013, and this second fin section 2013 and this aerofoil section 2011 are mutually angle ε, and the span of angle ε is 160 ° to 175 °.This first fin section 2012 and this second fin section 2013 are mutually angle ζ, and the span of angle ζ is 160 ° to 175 °.
By those blades are bent into this aerofoil section of comprising, this first fin section and this second fin section version, the axial draining flow of this agitator (along the axial draining flow of blade) increases again further.
Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
