Description

A kind of efficient flocculating device

Technical field

The utility model relates to the flocculation plant in the water treatment scavenging process.

Background technology

Flocculation plant is a crucial device in the water treatment scavenging process.Flocculation plant should help particle in the processed water body and fully assemble and form flocs unit, to help improving the effect that post precipitation is handled.The flocculation plant that a kind of eddy current type is arranged in the existing flocculation plant, eddy current type flocculation plant comprise the housing that contains the chamber of flocculating, and the hypomere of said housing is following bevel-type cone; Epimere is a cylinder, and water-in is arranged at the said bottom of bevel-type cone down, and there is mud discharging mouth the bottom; Water outlet is arranged at said cylinder top, and the water body that is processed gets into bevel-type cone down by the water-in of bottom, forms eddy current and diffusion; Current shape rotation in the shape of a spiral rise and form certain stirring intensity, organically combine with the lift velocity that gets into behind the cylinder, realize flow velocity by strong to weak transition; And accomplish whole flocculation process, have hydraulic detention time short (6-10min) and the little advantage of volume, but since current along under bevel-type cone spirrillum to rotate the quantitative proportion of the micro-vortex that forms in the uphill process low; Therefore, influence flocculating effect.

The utility model content

The purpose of the utility model is to propose a kind of efficient flocculating device that can effectively improve flocculating effect.

The technical scheme of the utility model comprises: contain the housing in the chamber of flocculating, the hypomere of said housing is following bevel-type cone, and epimere is a cylinder; Water-in is arranged at the said bottom of bevel-type cone down; There is mud discharging mouth the bottom, and water outlet is arranged at the top of said cylinder, and its improvement is; In the flocculation chamber of said housing, be provided with by several layers and have the built-up type dish flocculation member that the break plate of through hole is formed, the said built-up type dish member that flocculates is connected with said housing; Said built-up type dish flocculation member can be changed the direction of a stream of water and speed, increases particle collision number of times or probability, can improve the quantitative proportion of micro-vortex significantly.

The technique effect of the utility model is, because built-up type dish flocculation member is set in the flocculation chamber, makes current in bevel-type cone down, form when getting into built-up type dish flocculation member in the process that rises than maelstrom or eddy current; Break plate in the built-up type dish flocculation member then constantly changes the direction and the flow velocity of current; Bigger vortex breakdown is also diminished constantly, form micro-vortex, increase substantially the quantitative proportion of micro-vortex in the current; Increase particle collision number of times or probability simultaneously; Particle in the current is fully assembled, thereby effectively improved flocculating effect, with existing flocculation plant ratio; Under the situation of handling same design flow, dosage, flocculation hydraulic detention time 6-10min, the impurity particle removal efficient that post precipitation is handled can improve 10%-20%.

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Embodiment

Referring to Fig. 1, Fig. 2.The utility model comprises the housing 1 that contains the chamber 1a that flocculates; The hypomere of said housing is following bevel-type cone 1b; Epimere is cylinder 1c, and water-in 2 is arranged at the said bottom of bevel-type cone 1b down, and there is mud discharging mouth 3 bottom; Water outlet 4 is arranged at the top of said cylinder 1c; Be provided with in the flocculation chamber 1a of said housing by several layers and have the built-up type dish flocculation member 5 that the break plate of through hole is formed, said built-up type dish flocculation member 5 is connected with said housing through transom 6 and fixes, and the structure formation of connection has multiple; There is an overflow tank body 1d upper end of said cylinder 1c; The overflow groove of overflow tank body 1d communicates with port and the described water outlet 4 of cylinder 1c respectively; Said overflow tank body is set; Can make the current in the flocculation chamber 1a enter overflow groove equably, and then discharge, help the steady running of this device by water outlet 4 along cylinder 1c port.

Fig. 3 is the structure enlarged view of said built-up type dish flocculation member 5.In the diagram, the break plate 501 of said built-up type dish flocculation member 5 is 11 layers, is connected on the axle 502, and the break plate 501 of said built-up type dish flocculation member 5 also can be the several layers of other quantity; Distance between the adjacent break plate 501 is from the bottom to top gradually by little increase, to adapt to the current attenuation law of turbulent flow from the bottom to top; Comprise oblique shape through hole break plate 501a and vertical through hole break plate 501b in said some break plates 501; Said oblique shape through hole break plate 501a and the alternate layout of vertical through hole break plate 501b; And through-bore axis on the adjacent oblique shape through hole break plate 501a and the through-bore axis on the vertical through hole break plate 501b stagger each other, and number of openings on each break plate and sectional area thereof are confirmed according to handling the water yield; Its effect is: the one, and change the direction of a stream of water and increase particle collision number of times or probability; Form flocs unit to help agglomeration of particles; The 2nd, make than the current of maelstrom to diminish constantly after via the some through holes shunting fragmentations on the multilayer break plate, form micro-vortex, increase substantially the quantitative proportion of micro-vortex in the current; Particle to satisfy in the current is fully assembled, and further improves flocculating effect.

The working process of the utility model is; Water body after prime is handled is got in the flocculation chamber 1a by water-in 2 tangentials; Form that bigger vortex or eddy current state rise and get into built-up type dish flocculation member 5, and from the bottom to top successively via the vertical through hole break plate of multiwalled 501b and oblique shape through hole break plate 501a, constantly change the direction of a stream of water and increase particle collision number of times or probability; And increase considerably micro-vortex quantity; And the speed that current rise is by slow down soon, and the particle in the realization current is fully assembled and formed flocs unit, is discharged by water outlet 4 then and gets into follow-up precipitation process.

Various enforcement structures described in the utility model application documents and other any modification structures in the utility model technical scheme scope are all belonged to the protection domain of the utility model.
