A kind of mud agitating device
Technical field
This utility model relates to device for treating sludge field, particularly to a kind of mud agitating device.
Background technology
In sludge dewatering processing procedure, before sludge dewatering, need that mud adds flocculant carry out flocculating to facilitate dehydrating operations, it is understood that flocculation process: flocculant mixes with mud, suspended state (glue) thing process of agglomerate under the effect of flocculant in mud, reaches the purpose that mud is separated from water.This flocculation should keep the Homogeneous phase mixing state between mud and flocculant, also to keep floccule body being uniformly distributed in mud preliminarily formed, make floccule body average rate grow up, make tiny floccule body aggregate into big floccule body, to improve flocculating effect.This needs exist for a stirring operation, to provide mixing required for flocculation process and agglomerate condition.
At present, existing mud agitating device adopts an agitator tank, installs a blender, blender rotation speed constant in agitator tank, and flocculant mixes at agitator tank with mud, forms floccule body.In order to make mud in agitator tank mix with flocculant Quick uniform, general blender rotary speed is very big, and blender rotary speed will destroy very greatly floccule body, it is impossible to goes into bigger floccule body, causes flocculating effect poor, sludge dewatering poor processing effect.If reducing blender rotary speed, mud in agitator tank can be made to mix with flocculant uneven, flocculating effect can be caused equally poor, sludge dewatering poor processing effect.It addition, in existing agitator tank, one stops the rotation when blender, and the floccule body in agitator tank can precipitate downwards, it is not easy to discharge.
Utility model content
In view of this, the utility model proposes a kind of mud agitating device, with the problem solving flocculating effect difference and sludge dewatering poor processing effect.
On the one hand, this utility model provides a kind of mud agitating device, including the first staving and the second staving, first staving is connected to feeding pipe, second staving is connected to discharge nozzle, between the first staving and the second staving, it is provided with the passage of mutual UNICOM, the first staving is provided with the first blender, the second staving is provided with the second blender.
Further, passage makes to connect above the first staving and the second staving.
Further, passage is square groove, square groove upper opening, and square groove overhead height and the first staving and the second staving overhead height are equal.
Further, discharge nozzle is connected to bottom the second staving.

Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is mud agitating device of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
It should be noted that when not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As depicted in figs. 1 and 2, this utility model is a kind of mud agitating device preferably, have employed the design of segmentation stirring, it is achieved thereby that different mixing speeds.
As it is shown in figure 1, mud agitating device includes the first staving 1 and the second staving 2, the first staving 1 and the second staving 2 are arranged side by side, and the first staving 1 and the second staving 2 are drum, and the first staving 1 is highly identical with the second staving 2, and size is identical.First staving 1 and the second staving 2 open-top.First staving 1 and the second staving 2 form for Plate Welding, and the first staving 1 and the second staving 2 height and diameter are 4 meters.
In order to by mud input to the first staving 1, be connected to feeding pipe 5 on the first staving 1, feeding pipe 5 is connected to bottom the first staving 1, and feeding pipe 5 extends straight up.Feeding pipe 5 is welded on the outer wall of the first staving 1.Feeding pipe 5 is connected with pan feeding slush pump.In order to prevent mud backflow after pan feeding slush pump is shut down, feeding pipe 5 overhead height and the first staving 1 overhead height are equal.
In order to be discharged in the second staving 2 by mud, being connected to discharge nozzle 3 on the second staving 2, discharge nozzle 3 is connected to bottom the second staving 2, discharge nozzle 3 and the second staving 2 bottom welding.Discharge nozzle 3 is connected with discharging slush pump.
As depicted in figs. 1 and 2, in order to make the fluid in the first staving 1 flow in the second staving 2 after agitation, the top between the first staving 1 and the second staving 2 is provided with the passage 4 of mutual UNICOM.Passage 4 is square groove, square groove upper opening, and square groove is welded in the first staving 1 and the second staving 2 top, and the square groove degree of depth is 500MM, and square groove width is 500MM.Square groove overhead height and the first staving 1 and the second staving 2 overhead height are equal.It addition, passage 4 can also adopt circular port or pipeline to make to communicate above the first staving 1 and the second staving 2.
As depicted in figs. 1 and 2, in order to realize different mixing speed, the first staving 1 is provided with the first blender 6, the second staving 2 is provided with the second blender 7.In use, flocculant adds to the first staving 1, and the first blender 6 high speed rotating, the rotating speed of the first blender 6 is so that mud and flocculant Quick uniform are mixed into suitable.Second blender 7 rotates at a slow speed, and the rotating speed of the second blender 7 is not so that mud in the second staving 2 produces to be precipitated as suitable.Mud in first staving 1 and flocculant, in high-speed rotation, flow from bottom to top, make the mud in the first staving 1 and the quick mix homogeneously of flocculant.Mixed mixture flows in the second staving 2 by passage 4, and the mixture in the second entire body can produce tiny vortex at stirring at low speed process, mud and flocculant mixture in the second staving 2, will not destroy floccule body.Flocculation rapidly, the agglomerate time is short and floc density high, and floccule body is in suspended state, conveniently discharges.Improve flocculating effect and sludge dewatering effect.Further, since the mixture rotary speed in the second staving 2 is lower than the mixture rotary speed in the first staving 1, mixture will not pass through the passage 4 at top and flow in the first staving 1.
As it is shown in figure 1, the first blender 6 and the second blender 7 all include motor 11 and reductor 12 and stirring rachis 13, motor 11 is connected with reductor 12, and reductor 12 is connected with stirring rachis 13.First blender 6 and the second blender 7 are separate, thus realizing different rotary speeies.In use, the first blender 6 rotating speed is more than the second blender 7 rotating speed.
As shown in Figure 2, in order to conveniently fix the first blender 6 and the second blender 7, at the first staving 1 top, the first support 8 is installed, at the second staving 2 top, the second support 9 is installed, first blender 6 is arranged on the first support 8, and the second blender 7 is arranged on the second support 9.
As it is shown in figure 1, in order to ensure its bearing capacity, it is ensured that safety.Being respectively connected with pillar 10 below first support 8 and the second support 9, pillar 10 extends downward bottom the first staving 1 and the second staving 2.Pillar 10 can be arranged in the first staving 1 and the second staving 2, it is also possible to is arranged at outside the first staving 1 and the second staving 2.
It addition, this utility model can also adopt, and the first staving 1 and the second staving 2 are sized to different two staving, the first staving 1 is mounted in the second staving 2, or the second staving 2 is mounted in the first staving 1.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
