Abstract

The utility model discloses a concentration tank. The concentration tank comprises an upper tank body and a lower tank body, wherein an overflow port is arranged on the edge of the upper tank body; both the upper tank body and the lower tank body are conical; the taper of the upper tank body is greater than that of the lower tank body; a flocculation bridge frame is arranged on the top of the upper tank body and provided with a nozzle and a submerged pump which is connected with the nozzle; a foam check ring is arranged below the flocculation bridge frame; the nozzle is arranged inside the foam check ring; and a drain outlet is arranged at the bottom of the lower tank body and connected with a siphon pipe. The concentration tank overcomes the shortage of the prior art; by virtue of the upper and lower conical tank body differing in taper, the concentration rate is enhanced without increasing the depth of the tank body; foam can be eliminated by spraying water downward through the nozzle; and sewage is discharged from the drain outlet at the bottom of the tank based on a siphon principle, so that energy is saved.

Description

A kind of concentration basin
Technical field
The utility model relates to a kind of mill water treatment facility, especially a kind of concentration basin.
Background technology
In ore-dressing technique, concentration basin is that the sewage that is mixed with suspended particulate is carried out to flocculating setting, obtains the equipment of recycled recirculated water.At present, the enrichment factor of domestic concentration basin is only 60%~70%, and concentrated effect is not good enough.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of concentration basin, can solve the deficiencies in the prior art, by designing the different two terminal circle conical tank body of upper and lower tapering, do not increasing under the prerequisite of the pond body degree of depth, improved enrichment factor, by nozzle, spray current downwards, play the effect of eliminating foam.Sewage draining exit at the bottom of pond utilizes siphon principle blowdown, saves the energy.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A concentration basin, comprises upper pool body and lower pool body, at the edge of upper pool body, is provided with overfall, and described upper pool body and lower pool body are taper shape, and the tapering of described upper pool body is greater than the tapering of described lower pool body; At the top of described upper pool body, be provided with flocculation crane span structure, flocculation crane span structure is provided with nozzle and the immersible pump being connected with nozzle, below flocculation crane span structure, is provided with foam back-up ring, and nozzle is in the inside of foam back-up ring; Bottom at lower pool body is provided with sewage draining exit, and sewage draining exit is connected with siphon pipe.
As preferably, the tapering of described upper pool body is 4.5, and the tapering of described lower pool body is 2.5.
As preferably, on described siphon pipe, be provided with switch valve.
As preferably, described upper pool body and lower pool body inner side are equipped with watertight composition.
The beneficial effect that adopts technique scheme to bring is: upper pool body and lower pool body adopt the design of different taperings, can under the prerequisite that does not increase the concentration basin degree of depth, improve the dischargeable capacity of concentration basin, have increased hydraulic detention time, have improved enrichment factor.In addition, this design is applicable to concentrated mechanical maximization more.It is inner that foam back-up ring can be limited in foam back-up ring the foam producing, and by immersible pump, constantly extracted water and sprayed by nozzle, effectively reduced the foam in concentration basin.Sewage draining exit adopts siphon principle, saves the energy.The switch valve arranging on siphon pipe can be controlled siphonal break-make.The watertight composition of upper pool body and lower pool body inner side can effectively stop seepage, extends the service life of concentration basin.Through above-mentioned optimization, thickening efficiency can be increased to 88.2%.
accompanying drawing explanation
Fig. 1 is the schematic diagram of a specific embodiment of the utility model.
In figure: 1, upper pool body; 2, lower pool body; 3, overfall; 4, flocculation crane span structure; 5, nozzle; 6, immersible pump; 7, foam back-up ring; 8, sewage draining exit; 9, siphon pipe; 10, switch valve; 11, watertight composition.
The specific embodiment
With reference to Fig. 1, the utility model comprises upper pool body 1 and lower pool body 2, at the edge of upper pool body 1, is provided with overfall 3, and described upper pool body 1 and lower pool body 2 are taper shape, and the tapering of described upper pool body 1 is greater than the tapering of described lower pool body 2; At the top of described upper pool body 1, be provided with flocculation crane span structure 4, flocculation crane span structure 4 is provided with nozzle 5 and the immersible pump 6 being connected with nozzle 5, below flocculation crane span structure 4, is provided with foam back-up ring 7, and nozzle 5 is in the inside of foam back-up ring 7; In the bottom of lower pool body 2, be provided with sewage draining exit 8, sewage draining exit 8 is connected with siphon pipe 9.
Tapering that it should be noted that described upper pool body 1 is 4.5, and the tapering of described lower pool body 2 is 2.5.
It should be noted that: on described siphon pipe 9, be provided with switch valve 10.
In addition, described upper pool body 1 and lower pool body 2 inner sides are equipped with watertight composition 11.
Operation principle of the present utility model is: silt particle suspension is after cyclone classification, and the thin mud suspension of granularity-0.045mm enters in concentration basin.Meanwhile, according to set regime of agent, add flocculant, make the particle generation Flocculation Settling Process in suspension.In Flocculation Settling Process, thin mud particle forms large floc sedimentation under the effect of flocculation bridge formation 4, at the bottom of sinking to pond, forms concentrated underflow, by sewage draining exit 8, discharges; The few water of solid content is discharged by overfall 3, becomes recirculated water.Reached the object of mud-water separation.
The design of upper pool body 1 and the different taperings of lower pool body 2 employing can improve the dischargeable capacity of concentration basin under the prerequisite that does not increase the concentration basin degree of depth, has increased hydraulic detention time, has improved enrichment factor.In addition, this design is applicable to concentrated mechanical maximization more.Foam back-up ring 7 can be limited in foam back-up ring 7 inside the foam producing, and by immersible pump 6, is constantly extracted water and is sprayed by nozzle 5, has effectively reduced the foam in concentration basin.Sewage draining exit 8 adopts siphon principle, saves the energy.The switch valve 10 arranging on siphon pipe 9 can be controlled the break-make of siphon pipe 9.The watertight composition 11 of upper pool body 1 and lower pool body 2 inner sides can effectively stop seepage, extends the service life of concentration basin.Through above-mentioned optimization, thickening efficiency can be increased to 88.2%.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
