The underwater components of the stirrer are made of 304 stainless steel, when flocculation stirring is started, the stirring shaft of the starting button is pressed down to drive the blades to rotate and stir, and when the flocculation stirring is stopped, the closing button is only pressed down.
Before dewatering, the sludge must be subjected to a flocculation process, i.e. a suspension is pretreated by a flocculant (i.e. a polymer-polyelectrolyte), and the flocculant and the sludge are stirred and mixed to cause solid phase particles in the suspension to be bonded to generate a coagulation phenomenon, so that a solid phase is separated from a liquid phase. Sometimes small amounts of coagulant aids are added to increase the flocculation effect or to increase the floc strength.
However, the existing sludge flocculation stirring machine comprises: the clear liquid can not be discharged when the flocculated sludge is stored, and the device has large volume and small treatment and can not improve the sludge concentration.

FIG. 1 is a schematic structural view of a conventional sludge flocculation blender;
FIG. 2 is a schematic structural diagram of a concentrated sludge flocculation blender according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 2, an embodiment of the present invention provides a concentrated sludge flocculation stirring machine, including: a driving device 21, a stirring shaft 22, a blade 23, a circular stirring barrel 24 and a dehydration filtering device 25; wherein,
drive arrangement 21 establishes circular agitator 24 upper end, drive arrangement 21 connects (mixing) shaft 22 establishes in the circular agitator 24, the front end of (mixing) shaft 22 sets up paddle 23, set up in the circular agitator 24 dehydration filter equipment 25, dehydration filter equipment 25 establishes above the paddle 23, dehydration filter equipment's fixed part 251 with circular agitator 24 fixed connection, dehydration filter equipment's rotating member 252 with (mixing) shaft 22 fixed connection.
In the above-mentioned flocculation stirring machine, the dewatering and filtering device 25 is composed of two grid cylindrical structures, the grids of the two grid cylindrical structures are inserted at intervals, one of the grid cylindrical structures is fixedly connected with the circular stirring barrel 24 as a fixing component 251, the other grid cylindrical structure is fixedly connected with the stirring shaft 22 as a rotating component 252, and the grid cylindrical structure as a rotating component can be driven by the stirring shaft 22 to move relative to the grid cylindrical structure as a fixing component to perform filtering. This dehydration filter equipment 25 is wholly established on paddle 23 and the both sides of (mixing) shaft 22 for this dehydration filter equipment has the dehydration function because two bars cylindric structure body relative motion, makes to discharge the clear liquid at any time after forming flocculation sludge, aggravates the flocculation of mud once more, improves the mud concentration that gets into the hydroextractor.
Preferably, the driving device in the flocculation stirrer adopts a stepless speed regulating motor, and can adapt to stirring strengths of different liquid levels.
The flocculation stirrer has the advantages of low manufacturing cost, small volume, pre-dewatering function and convenient transportation.
The mixer of the present invention is further described below with reference to specific examples.
