Description
Technical field:
The utility model belongs to cyclone separation device, says it is a kind of cyclone clarification device that is used for fine granule material dehydration usefulness in detail.
Background technology:
We know, particle diameter is more little, sinking speed is slow more, therefore the dehydration to fine granule material is comparatively difficult, at home and abroad the fine particle stage material dehydration is adopted the increase settling area usually, increases the particle time of staying, added methods such as flocculant or flocculating agent at present, domestic for handle metal mine microfine mine tailing from external import large diameter concentrator, attenuate or mine tailing slurry concentration when increasing in the mine tailing granularity, overflow also occurred and run the phenomenon of mixing, major diameter concentrator periphery transmission system requires also very high simultaneously.In order to increase settling area; at the inner swash plate of inclination of installing of settler; the space that inside is divided into certain intervals; owing to adopted a large amount of compact sedimentation faces of filling; a very big floor projection settling area can be provided in a smaller volume; therefore the efficient means of a process intensification is provided; because backflowing of discharge opeing passed through low concentration region; and particle aggregation also flows downward along the upper surface on inclined plane; these convection current can be upset by the flow instability that takes place under some situation usually, have reduced the useful influence of the existence on inclined plane to sinking speed.
In order to increase sinking speed, in most of the cases, adopt and add flocculant, in the adition process of flocculant, must stirred suspension with the impact polymer degree of scatter and increase intergranular impact velocity, particularly in the processing procedure of big flow slip, because flocculant is clarified and the effect that concentrates with bad influence of mixing between the suspension.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of novel structure, dewatering efficiency height, effective cyclone clarification device are provided.
The utility model can reach by following measure:
A kind of cyclone clarification device, be provided with cylinder, the cylinder below is provided with cone, cylinder and cone form the post cone, the cylinder top is provided with overflow launder, overflow launder is provided with drainpipe, it is characterized in that being provided with in the cylinder charging rotary fluid, insert flocculant in the middle of the charging rotary fluid and add pipe, a side of charging rotary fluid is equipped with feed pipe, the inclined tube of adjustable angle and insertion depth is equipped with in post cone inside, the underflow delivery pipe is equipped with in the cone below, and the underflow delivery pipe is provided with baiting valve, and cone is provided with sensor, baiting valve is connected with automaton with sensor, regulates the open degree of underflow drain valve automatically.
The charging rotary fluid is a cylindrical drum in the utility model, be installed in cylindrical central authorities through overflow launder, feed pipe is located on the tangent line of charging rotary fluid one side, and flocculant adds pipe and is installed on the center line of charging rotary fluid through overflow launder, its top is hollow stem, and it is horn-like that the bottom is.
Inclined tube in the utility model is installed on the overflow launder.
When the utility model uses, fine granule material enters rotary fluid by feed pipe, than coarse granule in limit, centrifugal action lower edge wall rapid subsidence, fine granule material sinking speed under the effect of centrifugal force that eddy flow produces increases, strengthen separation process, and the interior eddy flow that utilizes eddy flow to produce fully mixes flocculant with suspension formation floc sedimentation acceleration sedimentation.The floc sedimentation that has subparticle enters the inclined tube of being located at the decanting zone in the decline process, carry out abundant sedimentation, in the decanting zone, add inclined tube, be in the confined space, to have increased settling area, shorten the particles settling distance, and the laminar flow of microfine ore pulp has been created condition, relied on the filtration of static floc sedimentation, stop fine grain motion, reduced the overflow solid content.Adopt long cone form, make the floc sedimentation of sedimentation produce extrusion effect, thereby improve underflow density, the self-con-tained unit that relies on the cone bottom to be provided with, by the conversion of pressure and concentration, adjust the open degree of underflow valve automatically, stablize solid content low in underflow density and the overflow water thereby reach.
The utility model combines the advantage of eddy flow sedimentation and inclined plate sedimentation, when satisfying the requirement of production backwater, can also obtain the bigger underflow product of concentration, be applicable in the operations such as recovery of dehydration, chemical field micro-size fraction material of processing, the environmental protection field mud of field, mine microfine mine tailing.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, cylinder 5 tops are provided with overflow launder 1, clear water discharge pipe 4 is installed on the overflow launder 1, be provided with charging rotary fluid 2 through overflow launder 1 in the middle of the cylinder 5, on the tangent line of charging rotary fluid 2 one sides feed pipe 7 is housed, the middle flocculant that inserts adds pipe 3, cylinder 5 belows are equipped with cone 8, underflow delivery pipe 9 and electronic (pneumatic) blow-off valve 10 are arranged at cone 8 bottoms, be equipped with inclined tube 6 between the post cone, flocculant adds pipe 3 and inclined tube 6 also is mounted on the overflow launder 1, cone one side is equipped with pressure sensor 12, pressure sensor 12 is connected with automaton 11 with electronic (pneumatic) blow-off valve 10, and automaton 11 is same as the prior art, and this does not give unnecessary details.
