Follow-on solid-liquid-gas triphase fractional cyclone
The present invention relates to solid-liquid-gas triphase fractional cyclone, particularly in the solid-liquid gas three-phase to the modified cyclone of solids high-effective classifying.
In the prior art, be used for the mine, metallurgical, chemical industry, power plant, carry out the equipment of Separation of Solid and Liquid in the industry such as coal, mostly adopt spiral classifier, the shortcoming of this spiral classifier is that the classification efficiency of solids is low, generally have only about 50%, it is the granule that also accompanies in the bulky grain about 50%, so, must pass through broken process again, so not only time-consuming taking a lot of work, main is, and that original granule becomes is thinner, do not reach the purpose of original classification, next is that this spiral classifier is bulky, and the life-span is extremely short, generally can only use 2-3 month and will upgrade.
In recent years, though have the report of solid-liquid-gas triphase fractional cyclone, as ZL-92205962.4, though classification efficiency brings up to 75%, also do not reach desirable requirements at the higher level, it is shorter also to exist equipment life simultaneously, generally has only 1-2.
The objective of the invention is to be to provide a kind of modified solid-liquid-gas triphase fractional cyclone of reforming on the basis of ZL-92205962.4, its classification efficiency can reach more than 82%, and the life-span is more than 2 years.
The embodiment of patent of the present invention is as follows: it is by advancing to starch short tube, spin chamber, cone pipe, outlet, going up overflow pipe and formed, wherein, the left side of spin chamber is into to starch short tube, then be the cone pipe below, the bottom is an outlet, and the lower end of last overflow pipe is in the spin chamber, the upper end then is exposed at the outside, spin chamber, particularly advancing to starch short tube is with the direction that connects the spin chamber, and its diameter diminishes gradually and becomes rectangle gradually, and last and cyclone junction is a rectangle.
Following preference elaborates to the present invention in conjunction with the accompanying drawings, but does not mean that its scope that limits.

Slip (solid-liquid phase) is behind charging short tube 1 as can be seen from Figures 2 and 3, because caliber dwindles gradually and becomes rectangle gradually, gradually become the rectangle pipe by round tube, are rectangles promptly with spin chamber's 2 connecting places, the effect of this special pipe is to make not only speedup but also guide to enter spin chamber 2 of slip, because caliber dwindles, flow velocity speeds, with because the import department that when entering spin chamber (2) is is a rectangle, so can play the guiding role, promptly enter spin chamber's 2 back slips and become laminar condition by turbulent condition, help big, the separation of little solid particle, big particle (carrying the part granule secretly) descend along spin chamber's 2 inwalls with liquid and enter in the cone pipe 3, granule then flows out from last overflow pipe (5) with liquid and air.Slip is accelerated (owing to be the cone of reducing) its speed once again and reaches and make cone pipe 3 centers cause negative pressure in cone pipe 3, cause air to enter from outlet 4 centers, promptly form solid-liquid gas three-phase, this negative pressure is introduced air, the bulky grain that helps entering cone pipe 3 and be is carried short grained separation secretly, i.e. the 2nd classification, introduce air carry secretly granule with from the spin chamber 2 little of telling flow out from overflow pipe 5 simultaneously, bulky grain and liquid then flow out from the wall of outlet 4, thereby improved classification efficiency widely, it is the feature of this equipment that the relative motion simultaneously of this solid-liquid gas three-phase flow causes field of force effect.
Advantage of the present invention is to be: the classification efficiency height of the size particles in the slip, and than spiral branch The level machine exceeds about 20-30%, bulky grain need not be pulverized again. Secondly equipment volume little, Little power consumption can save energy about 60%, be very suitable for controlling gold, mine, environmental protection, chemical industry, coal, The industry such as paper pulp.
