In addition, tank base can't obtain the abundant stirring of agitator, and often has the raw material depositional phenomenon that causes because stirring inequality.
The utility model content
The technical problems to be solved in the utility model is often to exist because stirring the defective of the raw material deposition that inequality causes for the bottom that overcomes anaerobic fermentation tank in prior art, a kind of anaerobic fermentation tank is provided, and the bottom of this anaerobic fermentation tank not only stirs nor has the problem of raw material deposition.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of anaerobic fermentation tank, its characteristics be, this anaerobic fermentation tank comprises that also one is positioned at the liquid-blocking device of the bottom of this anaerobic fermentation tank, this liquid-blocking device be used for stopping and reflection shot to its fluid.
Preferably, this liquid-blocking device comprises at least one slope or an arc.
Preferably, this slope is cone surface, or this arc is parabola.
Preferably, also be provided with a plurality of agitators in this anaerobic fermentation tank, each agitator comprises a turning axle and a paddle wheel, the axis of each turning axle has one first projection line in the axis determined plane of the normal of the connecting zone of this turning axle and this tank body, each first projection line becomes the angle of 20 ° to 70 ° with the corresponding normal of this first projection line.
Preferably, the axis of each turning axle is at the normal of the connecting zone of crossing this turning axle and vertically have one second projection line in the plane of the axis of this tank body, and each second projection line becomes the angle of 20 ° to 70 ° with the corresponding normal of this second projection line.
The utility model provides a kind of anaerobic fermentation tank.By increasing liquid-blocking device, fluid will strike liquid-blocking device by the middle level of anaerobic fermentation tank or upper strata after discharged to the bottom of tank body through those agitators, and produce the fluid tumbling motion and be back to middle level, upper strata or the inner tank wall surrounding of anaerobic fermentation tank, avoided the precipitation of solid matter.

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 3, the anaerobic fermentation tank 6 of the present embodiment comprises a tank body 61, eight agitators 5 and a liquid-blocking device 66.This tank body 61 has an axis 62.Each agitator 5 is fixedly connected with by the connecting zone of its turning axle 50 with the inner-wall surface of this tank body 61.This liquid-blocking device 66 comprises at least one slope, and those slopes are used for stopping that also reflection shot is to its fluid.
As shown in Figure 3, the axis of each turning axle 50 forms first projection line 501 that is projected as in the plane at the normal 63 of its connecting zone and this axis 62.This first projection line 501 is α with the angle of this normal 63, and the α span is 20 ° to 70 °, so this turning axle 50 has along the axial inclination of columniform tank body, i.e. axially incline.Because turning axle 50 has axially incline, during use, this fluid wave 64 has the shunting 65 that has a down dip discharged to this liquid-blocking device 66, the rear formation downslide of this liquid-blocking device 66 shunting 67 and convolution shunting 68 are being clashed in this shunting 65 that has a down dip, and then impel fermented liquid to form along the axial tumble mixed of tank body, realize that finally uniform stirring and the raw material of this anaerobic fermentation tank 6 bottoms do not deposit.
As shown in Figure 4, the axis of each turning axle 50 at the normal 63 of crossing its connecting zone perpendicular to second projection line 502 that is projected as in the plane of this axis 62.This second projection line 502 is β with the angle of this normal 63, and the β span is also 20 ° to 70 °, so this turning axle 50 has along tank body inclination radially, i.e. radial skew.Because this turning axle 50 has radial skew, during use, those agitators 5 are except carrying out individually local Stirring to fermented liquid, also has local vortex shunting 640, those local vortex shunting 640 actings in conjunction, drive fermented liquid around the whole eddying motion of axis 62 of this tank body 61, therefore form fermented liquid along the tumble mixed radially of this tank body 61, fermented liquid has obtained improving further through uniformity coefficient after the tumble mixed radially of this tank body 61.
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 paddle wheel and used liquid-blocking device.In addition, original bubble floats and the liquid circulation 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 substratum 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 fermented liquid is only 0.012kw/m 3(44kw/3500m 3), so the unit volume power of agitator is extremely low, i.e. discharge opeing efficient is higher.
As shown in Figure 5, in the anaerobic fermentation tank of the present embodiment, paraboloidal form that this liquid-blocking device 66 can also adopt that Open Side Down, this moment, the bottom of this liquid-blocking device 66 needed supporting rod 69, and supporting rod 69 can use commercially available joist steel.
Although more than described 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.
