Description

A kind of modified version coagulation device

Technical field

The utility model relates to technical field of water treatment equipment, particularly a kind of modified version coagulation device.

Background technology

Compared with mixing facility with waterpower, the efficient height of Mechanical coagulation Stirring device, can with water quality and quantity, coagulation dosage and kind change and make corresponding adjustment to reach the advantage of optimum handling effect, under normal circumstances, in mechanical stirring optimal flow pattern be current along stir shaft from bottom to top, top-downly near wall again to circulate, this Recycle design has very strong convection action, certain turbulent diffusion ability can be provided again, and existing axial-flow machines stirring can only form the highly unstable convection action of three peacekeepings, cause agitator stirring efficiency low, power is large, coagulating agent dispersion is uneven, local coagulant concentration is too high, affect the hydrolysis of coagulating agent and the colloid action in water thereof.

Utility model content

Therefore, for above-mentioned problem, the utility model proposes a kind of diffusion that can effectively make coagulating agent full and uniform, coagulant concentration is evenly distributed, sewage and the sufficient modified version coagulation device of coagulating agent coagulation.

For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of modified version coagulation device, comprise coagulation basin body and stir shaft, coagulation chamber is provided with in described coagulation basin body, the stirring end of described stir shaft is placed in the coagulation chamber of described coagulation basin body, the described axial wall stirring end is convexly equipped with the screw-blade that threaded shaft wall spirals from top to bottom; Described stirring end is above also equally spaced is provided with lateral strut, described lateral strut and described stirring are held in vertical relation, the lateral length of described lateral strut axially increases gradually along stir shaft and reduces gradually, two curved surface buckets in class " ∫ " shape are provided with between adjacent transverse pole, cross-distribution between two curved surface buckets, the axial wall of described stirring end is between two curved surface buckets; Described stir end axial wall on be also provided with multiple centered by stir shaft axle in the agitator arm dispersing distribution, connected by a bent union lever between the free end of wherein every two agitator arms distributed axisymmetricly, the point of crossing that between each bent union lever, intersection is formed mutually is positioned at stir shaft axially, each agitator arm and bent union lever together constitute Openworks shape stirring-head, and described screw-blade, curved surface bucket are positioned at described Openworks shape stirring-head; The chamber wall in described coagulation chamber is convexly equipped with projection.

Further: the cross section of described projection is for being fairshaped drops cross section, the front edge in described drops cross section is camber line edge, the afterbody in the two side direction drops cross sections at described camber line edge shrinks gradually, and the sidewall on the extrude depth direction of described projection is waisting shape structure; The front end of described projection is towards the flow direction of current.

By adopting preceding solution, the beneficial effect that the utility model compared with prior art has is:

1, the modified version coagulation device of design as mentioned above, the stirring end of stir shaft is provided with the whipped-up structure of agitator arm, curved surface bucket, screw-blade three-in-one type, agitator arm can produce shearing force to the coagulation sewage in coagulation chamber, be stirred the coagulation sewage Rotational diffusion under shearing force that bar stirs, the coagulation sewage collides wall at wall place, coagulation chamber realizes stirring up and down, curved surface bucket is located between agitator arm, and cross one another curved surface bucket constitutes the spiral structure be mutually wound around, the part coagulation sewage not then being subject to shear action between agitator arm can disperse to surrounding and do axially to move up and down under the curved surface bucket of this structure, coagulation sewage is made to form a cycling stream, promote the activity ratio of coagulating agent molecule and sewage molecule in coagulation sewage, promote the collision rate of coagulating agent molecule and sewage molecule, in order to further promote the axial castering action of curved surface bucket, the coagulation sewage of screw-blade on stir shaft axial wall between curved surface bucket to axle center plays upper and lower tipping effect, avoid part coagulation sewage to twine investing axial wall must be arrived effective coagulation, therefore, the agitator arm of described modified version coagulation device, curved surface bucket, the whipped-up structure of screw-blade three-in-one type, the coagulation sewage in coagulation chamber is made to be in rotation coagulation moving process without the moment at dead angle, fully improve the reactivity between coagulating agent molecule and sewage molecule, improve the probability of collision between coagulating agent molecule and sewage molecule, the diffusion that can effectively make coagulating agent full and uniform, coagulant concentration is evenly distributed, sewage and coagulating agent coagulation abundant.

The chamber wall in 2, described coagulation chamber is also provided with projection, when then coagulation sewage forms the rotating fluid run up, strong impact effect can be there is at high speeds in the rotating fluid constantly spread towards periphery with the projection on the wall of chamber, this impact effect further can promote intermolecular probability of collision, also further improves coagulation effect; Further, the cross section of described projection is for being fairshaped drops cross section, protruding contraction tail end is in face of the flow direction of current, then understand being shunted rapidly by the contraction tail end of angled arrangement of front in current flow process, draw in along edge effect towards the arcuate front ends of projection again, namely the multinomial reactive forces such as surging force that converge after the shunting power of described protruding tail end, shunting further improve probability of collision between coagulation sewage Middle molecule, improve coagulation effect; And the sidewall of described projection is waisting shape structure, greatly reduce the obstructive of current flowing, the high speed that current are remained valid can be made, current are collided with the projection of fast state and next section, promote the diffusion collision scope of current molecule, further improve coagulation effect, practicality is high.
