A kind of concentrator flocculant highly effective coagulation adding set
It the utility model is related to charging gear, and in particular to a kind of concentrator flocculant highly effective coagulation adding set.
Concentrator is the solid-liquid separating equipment based on gravitational settling effect, is widely used in hydrometallurgy, ore dressing plant, chemical plant
Etc. the Workplace for needing solid-liquid concentration and separation, concentrator is widely used in ore dressing plant, is mainly used in leachate concentration and waste water
Processing etc. needs the technique of separation of solid and liquid, and it mainly includes several corollary systems：Flocculant add-on system, deaerating tank and automatic control
System processed, flocculant can play cohesion to solid particle, ore pulp particle is fully reunited, traditional concentrator wadding
The connection of solidifying agent add-on system is generally diversing bucket in flocculant head tank-concentrator center adding tube-concentrator, wherein dense
Close machine center adding tube typically uses common steel tube, and ore pulp freely mixes in common steel tube, because stroke is shorter, two fluids
Coagulation effect is poor, and flocculant can not be sufficiently mixed with ore pulp, and ore pulp particle is not reunited fully, so as to cause flocculant unrestrained
The content of the invention
The problem of existing for prior art, the utility model provide a kind of concentrator flocculant highly effective coagulation addition dress
To put, the present apparatus mainly plays a part of flocculant by the helical structure of concentrator center adding tube and mixed with ore pulp reinforcing,
Improve flocculant and ore pulp coagulation effect.
The technical solution adopted in the utility model is：A kind of concentrator flocculant highly effective coagulation adding set, including flocculation
Agent head tank, center adding tube, flocculant adding mouth, ore pulp adding mouth and central draft tube, it is characterised in that：The flocculant
Head tank lower end sets flocculant adding tube, and the port of export of the flocculant adding tube is connected with flocculant adding mouth by flange
Connect, one end of the centrally disposed adding tube of the flocculant adding mouth and ore pulp adding mouth, the center adding tube both ends with 5 ~
15 degree of the gradient is arranged on concentrator pool wall with central draft tube, helical blade is set in the center adding tube.
Preferably, one end that the center adding tube is connected with concentrator pool wall for be provided with flocculant adding mouth and
One end of ore pulp adding mouth.
Preferably, the ore pulp adding mouth is connected by flange with ore pulp adding tube.
Preferably, the flocculant head tank is arranged on concentrator crane span structure.
Compared with prior art, the beneficial effects of the utility model are：Described center adding tube uses helical pipe, by
Stroke and unsteady flow immixture are improved in thread mixing, flocculant mixes fully with ore pulp, and by bridge linking effect, ore pulp particle obtains
Reunite to abundant, agglomerated particle sinks to separating with supernatant rapidly, and supernatant rate is high, and supernatant suspended particulate is few, and supernatant quality is high, in reality
In the production of border, this adding set concentrator reduces 50% than the concentrator flocculant usage of common adding set, and supernatant rate improves
30%, suspension content also obtains very big reduction.
Brief description of the drawings
Fig. 1 is scheme of installation of the present utility model；
Fig. 2 is center tube structure figure of the present utility model.
Embodiment：In order to make it easy to understand, it is described further in conjunction with accompanying drawing, a kind of concentrator flocculant as shown in Figure 1
Highly effective coagulation adding set, including flocculant head tank 1, center adding tube 2, flocculant adding mouth 3, ore pulp adding mouth 4 and in
Heart guide shell 5, flocculant head tank 1 is installed on the concentrator crane span structure, and the lower end of flocculant head tank 1 sets flocculant adding tube
3；The both ends of center adding tube 2 are arranged on concentrator pool wall with 5 ~ 15 degree of the gradient and on central draft tube, flocculant adds
Mouth 3 and ore pulp adding mouth 4 are set divides with center adding tube 5 close to one end of pool wall, flocculant adding mouth 3 and ore pulp adding mouth 4
The port of export not with flocculant adding tube 6 and ore pulp adding tube 7 is connected by flange, and helical-blade is set in the center adding tube
Piece.The utility model, which improves mixing stroke, makes flocculant be sufficiently mixed with ore pulp, and ore pulp particle is fully reunited, and makes reunion
Grain is rapid to be sunk to separating with supernatant, reaches the purpose of high efficiency high quality.
