Description
Technical field
The present invention utilizes the centrifugal sedimentation principle of fluid to make the equipment of classification of solid particles, belongs to the classification of solid particles field.Be specially a kind of compartment-type multi-section cyclone grader.
Background technology
Solid hydrocyclone is little as a kind of volume, low cost of manufacture, safe and reliable liquid-liquid, solid-liquid and solid-separation equipment, has obtained application widely in industries such as ore dressing, oil, chemical industry, building, food.But traditional cyclone can only obtain two kinds of products and have problems such as the underflow particulate is carried secretly, the overflow race is thick, and classification efficiency is on the low side.In order to use hydrocyclone to carry out classification better, people are seeking to improve the method for its classification efficiency always.The patent No. is that 95236129.9 utility model patent discloses a kind of " cylinder cone barrel formula liquid cyclone ", this clasfficiator mainly is that the circular cone ring that adds certain angle in conventional hydrocyclone post awl junction is divided into two Room with classifying cyclone, in second Room tangential wash tub pipe is set, two sections classifications have been realized, classification efficiency is higher, but still belongs to two kinds of grading equipment.Patent No. 94242784.x disclosed " three-product cyclone sieve ", mainly be that cylindrical shell and conical section with traditional cyclone changes the sieve nest structure into, sieve nest structure periphery is with cylindrical shell and cone, realized the combination of eddy flow hydraulic classiciation and sieve classification, can isolate sieve goes up, sieves down and three kinds of products of overflow, but, the sieve pore blockade problem very easily occurs, thereby influence the sieve classification effect because the big centrifugal force major part that particle is subjected in the ore pulp rotary course concentrates on the sieve nest face.The JK type cyclone of D.P.Obeng and A.Mainza report and three-product cyclone device all are to utilize the double overflow tubular construction to realize that classification obtains three kinds of products, but it is dark that interior overflow pipe inserts the cylindrical shell degree of depth than outer overflow pipe, overflow two products are mixed to exist at the granularity branch and are reported to the leadship after accomplishing a task, and the separation accuracy of overflow two products is lower.
Summary of the invention
Task of the present invention is the defective that overcomes above-mentioned prior art, organically combines centrifugal sedimentation classification and sieve classification, provides a kind of material of can realizing by the granularity multiple fractionation, the compartment-type multi-section cyclone grader of high accuracy, fecund product.
The technical scheme that realizes above-mentioned task is: described compartment-type multi-section cyclone grader, comprise a horizontal positioned or the vertical cylindrical or cylinder divergent-cone wall of placing, cylindrical shell top have feeding pipe and with the overflow pipe of cylindrical shell concentric.It is characterized in that: the cylinder lateral wall design of this compartment-type multi-section cyclone grader has at least one tangential discharging opening, is provided with truncated cone-shaped screen cloth, hollow round platform and annulus in its cylindrical shell.This truncated cone-shaped screen cloth, hollow round platform and annulus are used in combination, and compartment-type multi-section cyclone grader is divided at least two cabin bodies.
Described truncated cone-shaped screen cloth is a taper, and its side is embedded with stainless steel cloth.The bottom surface of truncated cone-shaped screen cloth is fixed on the inwall of compartment-type multi-section cyclone grader cylindrical shell.
Described hollow round platform is a cone, and its outer rim is fixed on the inwall of compartment-type multi-section cyclone grader cylindrical shell.
Described annulus is a cylinder, and its outer rim and compartment-type multi-section cyclone grader cylinder inboard wall are fixed.
Tangential discharging opening on the cylinder lateral wall of described compartment-type multi-section cyclone grader lays respectively at the end of each cabin body.
Truncated cone-shaped screen cloth, hollow round platform and annulus that compartment-type multi-section cyclone grader of the present invention is designed as three kinds of different inner barrel plug-in units, can substitute mutually and are used in combination.
The fitting depth of described overflow pipe can be regulated as required, and its caliber also can dispose as required.
