Summary of the invention
The utility model is for deficiency of the prior art, solve traditional mud exhauster spoil disposal in prior art inhomogeneous and stop up the defects such as reduction, poor processing effect that the anaerobic digestor causing is effectively used volume, a kind of efficient mud discharging device of motorless medium-and-large-sized anaerobic digestor is provided, can reach the uniform effect of spoil disposal, guarantee that anaerobic digestion pot bottom is without the silt too much depositing.
The utility model is achieved through the following technical solutions:
The efficient mud discharging device of a kind of medium-and-large-sized anaerobic digestor described in the utility model comprises the spoil disposal house steward who is arranged on anaerobic digestion tank outside, the spoil disposal being connected on spoil disposal house steward by valve is responsible for, described spoil disposal supervisor is inserted on the sidewall of anaerobic digestor, the inner of spoil disposal supervisor is arranged in the inner chamber of anaerobic digestor, the bottom of described anaerobic digestor inner chamber is provided with central tube, described central tube is the tubular structure of hollow, the lower end of central tube is fixedly connected on the tank bottom of anaerobic digestor, the upper end closed of central tube, described spoil disposal is responsible on the sidewall that is connected to central tube and is communicated with central tube, on the sidewall of described central tube, be surrounded with many spoil disposal arms, the inner of described spoil disposal arm is fixedly connected on the sidewall of central tube and is communicated with central tube.
Described central tube has four, be separately positioned on the central point of anaerobic digestor inscribe square four edges line, described spoil disposal arm comprises long tube and short tube, and described long tube is distributed in the foursquare inside of described inscribe, and described short tube is distributed in the foursquare outside of inscribe.
Many spoil disposal arms are positioned in same level, and the tie point of spoil disposal supervisor and central tube is positioned at the top of spoil disposal arm, is also provided with mudhole on the sidewall of central tube, and described mudhole is positioned at the below of spoil disposal arm.
Compared with prior art, the utility model has the advantages that: added many spoil disposal supervisors and central tube, at the bottom of central tube is positioned at anaerobic digestor tank, many spoil disposal arms evenly lay around central tube, 4 spoil disposal arm central tubes evenly lay at the bottom of tank, spoil disposal arm ordered arrangement on each spoil disposal arm central tube, guarantees that the mouth of pipe of each spoil disposal arm forms certain spoil disposal region, thereby has guaranteed in whole anaerobic digestor without spoil disposal dead band.This device can guarantee effectively to use in anaerobic digestor the activity of volume and anaerobic sludge according to silt particle amount in anaerobic digestor by mud discharging device spoil disposal, has effectively avoided the interference of silt particle to streamflow regime, has guaranteed the processing efficiency of digester.The utility model is simple in structure, easy to operate, facility investment is few, does not need additionally to increase power, can reach good sludge discharge effects.
Accompanying drawing explanation
Fig. 1 is structure schematic top plan view of the present utility model.
The structural representation of cylinder centered by Fig. 2.
The plan structure schematic diagram that centered by Fig. 3, cylinder is connected with spoil disposal arm.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the efficient mud discharging device of a kind of medium-and-large-sized anaerobic digestor described in the utility model comprise be arranged on anaerobic digestion tank outside spoil disposal house steward 5, by valve, be connected to spoil disposal on spoil disposal house steward 5 supervisor 4, described spoil disposal supervisor 4 is inserted on the sidewall of anaerobic digestor, the inner of spoil disposal supervisor 4 is arranged in the inner chamber of anaerobic digestor, opens valve and can be responsible for 4 to dispatch mud in spoil disposal house steward 5 by spoil disposal.
The bottom of described anaerobic digestor inner chamber is provided with central tube 3, the tubular structure that described central tube 3 is hollow, the lower end of central tube 3 is fixedly connected on the tank bottom 1 of anaerobic digestor, the upper end closed of central tube 3, described spoil disposal supervisor 4 is connected on the sidewall of central tube 3 and is communicated with central tube 3, on the sidewall of described central tube 3, be surrounded with many spoil disposal arms 2, the inner of described spoil disposal arm 2 is fixedly connected on the sidewall of central tube 3 and is communicated with central tube 3.When valve 6 is opened, the mud in anaerobic digestor inner chamber enters central tube 3 by spoil disposal arm 2 under pressure, then enters spoil disposal supervisor 4 and spoil disposal house steward 5 by central tube 3, reaches the effect of getting rid of mud.As shown in Figure 2, many spoil disposal arms 2 are positioned in same level, and the tie point of spoil disposal supervisor 4 and central tube 3 is positioned at the top of spoil disposal arm 2, is also provided with mudhole 8 on the sidewall of central tube 3, and described mudhole 8 is positioned at the below of spoil disposal arm 2.Near mud central tube 3 directly enters central tube 3 by mudhole 8.Certainly, as another embodiment of the present utility model, on central tube 3, also can not establish mudhole 8.In addition, in order to expand the suction mud scope of each spoil disposal arm 2, a plurality of through holes can also be set on the sidewall of spoil disposal arm 2, described a plurality of through holes distribute along the axis of spoil disposal arm 2, and less the closer to the through hole diameter of central tube 3.Can expand like this suction mud scope of spoil disposal arm 2, can prevent that again the mud in spoil disposal arm 2 from flowing backwards.
