Abstract

A flocculation reaction burbling ball in the utility model relates to a hollow ball body which disturbs water current in the course of the flocculation reaction so that the micro vortex can be formed to improve the flocculation effect; two same hemisphere housings are buckled with each other through a cleft hand of a biggest contact circle edge and a reinforced bar and form the flocculation reaction burbling ball; a warp-wise bar and an across warp bar are connected with each other and form the hemisphere housing; the warp-wise bar and the across warp bar bends in a circle and forms a perforation to be passed through water. As water flows through the utility model and is cut and stirred two times in a short time, the water velocity needed to generate the micro vortex in large quantities can be reduced compared with the planar network vortex device, which can shorten the flowing distance of water and reduce the working volume of the flocculation reservoir or the flocculation machine and has relatively sound flocculation effect; meanwhile, the utility model has the advantage of convenient use, the utility model overcomes the shortcoming of the planar network which needs a fixed device or fixed measures and hence complicates the structure of the flocculation reservoir or flocculation machine.

Description

The flocculation reaction burbling ball

Technical field:

The utility model relates to a kind of flocculation reaction process disturbance current strengthen flocculating effect to form micro-vortex hollow ball that is used for.

Background technology:

Turbulent eddies theory according to Cole Mo Luofu (kolmogoroff), the vortex many not of uniform size that exists in the turbulent flow its size of destroyed back in flow process constantly reduces, when size reaches a certain minimum vortex characteristic size, vortex is local isotropism, velocity gradient is very big, and the tangential velocity of its center and its outer rim differs greatly.The particle that be in vortex center this moment has bigger speed owing to being subjected to bigger centrifugal action, is near the particle the vortex outer rim and comes in contact, collides constantly catching up with in the process of moving to the vortex outer rim.This micro-vortex theory is applied to flocculation process can significantly improves flocculating effect, obviously shorten the reaction time, save medicament simultaneously.In application process, how producing micro-vortex a large amount of and that suit the requirements is the key that can this theory bring into play its effect.Obtained in practice using more widely to produce micro-vortex by plane grid is set on the flow area of water, and obtained good effect, needed higher water velocity (to be generally 0.05～0.35m/s but this grid produces micro-vortex ^[1]), so just need the mobile distance of water very long to guarantee that flocculation time (generally gets 6～8min ^[1]), then be difficult to produce micro-vortex and reduce flocculating effect for lower water velocity; Plane grid needs fixture or fixation and makes flocculation basin or flocculator structure comparatively complicated in addition.

Summary of the invention:

The utility model can overcome the above-mentioned shortcoming of utilizing plane grid to produce micro-vortex, when lower water velocity, still can produce a large amount of micro-vortexs, so just can shorten water mobile distance, reduce the dischargeable capacity of flocculation basin or flocculator, and can obtain good flocculating effect, the utility model uses very convenient simultaneously, be filled in flocculation basin or the flocculator and get final product, do not need complicated fixture or fixation, the formation of spheroid is convenient in special construction design of the present utility model in addition.

When the utility model can produce a large amount of micro-vortexs when lower water velocity reason is that current pass spheroid, pass through double cutting, the disturbance of front and back two halves spheroid at short notice, simultaneously when current pass through front and back two halves spheroid, owing to the boundary layer separation of current takes place the inhibition of rib on the spheroid, thereby provide condition for the generation of micro-vortex.

Making material of the present utility model is engineering plastics.

Description of drawings:

Shown in structural representation of the present utility model such as the accompanying drawing 1 (last figure is a front view among Fig. 1, and figure below is a vertical view, and wherein the right half part of front view is a cutaway view), fasten mutually by two identical hemispherical shells and to form.(the picture left above is a front view among Fig. 2 for the structural representation of hemispherical shell such as accompanying drawing 2, lower-left figure is a vertical view, right figure is left cutaway view, wherein the right half part of front view is a cutaway view) shown in, be to be coupled to each other by warp-wise rib 2 and broadwise rib 3 to form, the eyelet 1 that warp-wise rib 2 and the formation of broadwise rib 3 corrals run through is to provide water stream channel, edge at the maximum circle of contact face of housing has reinforcement 4, make two housings constitute spheroid thereon with intensity that improves housing and cleft hand 5 fastenings of being convenient on another housing, jagged 6 on this external reinforcement 4 so that the two halves spherical shell when fastening the cleft hand 5 on another housing via breach 6 along reinforcement 4 around the direction turn buckle on reinforcement 4 and constitute spheroid.

The specific embodiment:

Each hemispherical shell is coupled to each other by warp-wise rib 2 and broadwise rib 3 and forms, warp-wise rib 2 and broadwise rib 3 corrals form the eyelet 1 that runs through, edge at the maximum circle of contact face of housing has reinforcement 4,1～8 cleft hand 5 and breach 6 that quantity is identical is arranged respectively on reinforcement 4, and cleft hand 5 and breach 6 interlaced arrangement also evenly distribute along circumference.
