The frustum-like shape that mixing vessel 1 reduces from the top to the bottom for cross-sectional area gradually.Those skilled in the art will appreciate that the frustum-like shape of saying that falls is the reverse taper part of removing behind the awl point here, and the upper and lower surfaces of the body of falling the frustum-like shape is parallel.In one of them example of the present invention, as shown in Figure 1, mixing vessel 1 that is to say that for the shape of falling the truncated cone behind the planar interception awl point that is parallel to facies basialis pyramidis the upper surface of mixing vessel 1 is a co-axial circle and parallel with lower surface.
Certainly, the present invention is not limited to this, and mixing vessel 1 also can be the shape of falling the truncated pyramid behind the planar interception awl point that is parallel to facies basialis pyramidis, and promptly upper surface is co-axial Polygons and parallel, perhaps other the shape of falling the truncated cone with lower surface.
On the sidewall of mixing vessel 1, the position of contiguous bottom is provided with mud inlet 11, and advance mud pipe 2 and link to each other with mud inlet 11 and be used for pending mud is sent into mixing vessel 1.Particularly, as shown in Figure 1, advance mud pipe 2 and pending mud is sent in the mixing vessel 1 through defeated dredge pump 21.In some embodiments of the invention, the opening direction of mud inlet 11 departs from the longitudinal center line of mixing vessel 1.Like this; Mud gets into according to behind the mixing vessel in the embodiment of the invention, produces unsteady flow speed rotating fluid upwards owing to have pressure, shown in eddy flow direction of a curve among Fig. 1; Medicament can further carry out hybrid reaction with mud in this makes progress speed change eddy flow process; Because the cross-sectional area of mixing vessel reduces from the top to the bottom gradually, makes that the flow velocity of mud when eddy flow makes progress is slack-off gradually, helps the flocculation of mud thus.
Alternatively, the opening direction of mud inlet 11 is the tangential direction of mixing vessel 1, that is to say, mud inlet 11 makes mud to get in the mixing vessel 1 along the tangential direction of mixing vessel, and without the longitudinal center line of mixing vessel 1.
In an example of the present invention, mud inlet 11 is formed on the sidewall of mixing vessel 1 and is adjacent with bottom face, promptly is formed on the sidewall near the bottom surface, shown in Fig. 1 and Fig. 2.And the opening direction of mud inlet 11 is the tangential direction of the bottom face of mixing vessel 1; Promptly advance the tangential direction of the bearing of trend of mud pipe 11 along the bottom face of mixing vessel 1; That is to say, make mud get in the mixing vessel along the tangential direction of the circular base end face of mixing vessel 1.Like this, owing to when mud gets in the mixing vessel 1, have certain pressure, therefore speed is faster when mud tangentially gets in the mixing vessel 1, collide stronger, thereby when eddy flow makes progress easier and medicament to mix flocculating effect better.
Chemical feed pipe 3 is sent into medicament in the mixing vessel 1, thereby so that medicament mixes with mud mud is flocculated.In one embodiment of the invention, as shown in Figure 1, be provided with dosing mouth 12 at the bottom end vicinity of mixing vessel 1, chemical feed pipe 3 link to each other with dosing mouth 12 be used for medicament for example flocculation agent send into mixing vessel 1.Particularly, chemical feed pipe 3 through loading pump 31 with medicament for example flocculation agent join in the mixing vessel 1.In one of them example of the present invention; Dosing mouth 12 is formed on on the mud pipe 2; Alternatively; Dosing mouth 12 is formed on the into position near mud inlet 11 of mud pipe 2, so that before getting into mixing vessel 1, earlier medicament is tentatively mixed with mud, medicament is upwards further mixing in the speed change eddy flow process with mud more then.
Yet; The present invention is not limited to this; In another example of the present invention, dosing mouth 12 also can be formed on (figure does not show) on the bottom face of mixing vessel 1, and medicament directly gets into the mixing vessel 1 from dosing mouth 12; Tentatively mix earlier with the mud from advance mud pipe 2 adding mixing vessels, upwards further mixing in the speed change eddy flow process again with mud then.Certainly, dosing mouth 12 also can also be formed on the sidewall of mixing vessel 1 and be adjacent with bottom face, promptly is formed on (figure does not show) on the sidewall near the bottom surface.
As shown in Figure 1; On the sidewall of mixing vessel 1, the position of adjacent top end is provided with mud mouth 13; Sludge out pipe 4 links to each other with mud mouth 13; The mixed solution of mud and water after flocculation in the mixing vessel 1 is discharged from mud mouth 13 and passes through sludge out pipe 4 then, is discharged from last in the water extracter that is admitted to next flow process behind the mud mixing equipment according to the embodiment of the invention to dewater.
On the bottom face of mixing vessel 1, be provided with drain 14, during cleaning mixing vessel 1 drain 14 opened so that the residue in the mixing vessel 1 is discharged from drain 14.In another embodiment of the present invention, the mud mixing equipment further comprises blow-down pipe 5.Blow-down pipe 5 is connected with drain 14, the residue in the mixing vessel 1 is discharged to the outside of mud mixing equipment.
