Abstract
The utility model discloses a wet-type spiral sieving classifier, composed of a screw classification section and a sieving section. The screw classification section is composed of a slot body (12), a shaft (1) and a screw blade (7) arranged on the shaft (1). The sieving section is composed of a sieve inner screw blade (4) and a barrel sieving body (3). The utility model combines the hydraulic classification and the sieving classification. The classification course is intensified. The classification efficiency and processing ability are largely increased. The utility model has the advantages of simple structure, convenient operation and maintenance, low manufacture cost, etc. The utility model can be used for wet type sieving classification operation for industries of metallurgy, construction material, coal, etc.
Description
The utility model relates to a kind of hydraulic classiciation and the symphyogenetic wet screening classifying equipoment of wet screening, can be widely used in the wet screening graded operation of industries such as coloured, metallurgical, building materials, coal.
The wet screening classifying equipoment of extensive use both at home and abroad can be divided into two big classes by its operation principle at present, and a class is different by the sinking speed of particle in water and hydraulic classiciation that carry out, as spiral classifier, hydrocyclone etc.; Another kind of is to carry out sieve classification according to the physical dimension of particle, as high frequency vibrating fine screen, drum sieve etc.In the mining processing industry of China is produced at present, use maximum spiral classifiers that is still, it is mainly formed by the circular arc cell body and by the screw that axle and helical blade are formed, its advantage be simple in structure, working stability is reliable, easy to operate, its fatal shortcoming is that classification efficiency is low, generally has only 20～40%.A kind of SL-A.B type Spiral classfier page has been introduced in " Chinese preparation equipment application manual " first volume P253～255 of publishing China Machine Press in April, 1992, this equipment is made up of two sections or the identical sieve of three-stage structure, sieve is stepped, each section sieve is made up of the helical axis of row's dextrorotation double thread and left-handed double thread, helical axis and grating thereof are formed compass screen surface, and its screen size does not wait between 6～100mm.SL-A.B type Spiral classfier overcomes the shortcoming that goes up the spiral classifier existence of using at present to a certain extent, classification efficiency is enhanced, but also exist simultaneously shortcomings such as complex structure, manufacturing cost height, partition size are thick, thereby also just limited applying of it.
The purpose of this utility model is exactly at the above-mentioned problems in the prior art, and the wet type screw sieving grader of a kind of classification efficiency height, widely applicable, simple in structure, with low cost, convenient operating maintenance is provided.
For achieving the above object, the utility model by the following technical solutions:
The utility model wet type screw sieving grader is formed by the two sections organic assembling in front and back, and leading portion is the screw classifying section, and back segment is a screening section, is provided with the screening charging aperture between two sections of the front and back.The screw classifying section is identical with the first half of general single-spiral classifier, promptly is made of circular arc cell body, axle and the helical blade that is installed on the axle; Screening section is the drum sieve that has internal helical blades.The coaxial rotation of forward and backward two sections helical blade and drum sieve is driven by transmission device.
The pitch of the helical blade in the above-mentioned drum sieve should can be improved grading effect like this less than the pitch of the helical blade of leading portion screw classifying section.The drum sieve charging aperture preferably adopts spoonful formula feeding manner and outer rim to add backpitch.
Compared with prior art, after the utility model wet type screw sieving grader adopts technique scheme, make it to have concurrently the two advantage of screw classifying and wet screening, it is in particular in:
1. screw classifying and sieve classification organically combine, and have strengthened classification process, and classification efficiency is enhanced.Commerical test shows that the utility model improves 10～15% than common spiral classifier classification efficiency.
2. owing to the raising of classification efficiency, the corresponding disposal ability that also increases equipment has reduced power consume, again because qualified grade obtains discharge immediately, and has alleviated the argillization phenomenon that produces because of overground, helps follow-up sorting operation.
3. can obtain to sieve, sieve products following, three kinds of size fractionated of screw classifying overflow.
4. structure is simple relatively, and cost of manufacture is cheap, and convenient operating maintenance is widely applicable.
For further describing the utility model, the utility model wet type screw sieving grader is described in more detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model wet type screw sieving grader structural representation.
In wet type screw sieving grader structural representation shown in Figure 1, the helical blade 7 of screw classifying section and sieve internal helical blades 4 totally rotating shaft 1 of screening section; The screw classifying section is identical with the forward part of general single-spiral classifier, promptly is made of annular cell body 12, axle 1 and the helical blade 7 that is installed on the axle 1, and is provided with screw classifying material inlet 8, downflow weir 9; Screening section mainly is made of the drum sieve 3 that has internal helical blades 4, is provided with flushing water pipe 5 outside the sieve outside drum sieve 3, is provided with sand-returning channel 10 below the sand return end, divides into undersize discharge gate 11 at sieve; Be provided with screening charging aperture 6 between screw classifying section, screening section, screening charging 6 is that spoon formula and outer rim have backpitch.In actual use, transmission device 13 drives screw classifying section helical blade 7, screening section sieve internal helical blades 4, drum sieve 3 rotations by axle 1.Material to be fractionated feeds from screw classifying section material inlet 8, and the stirring of material helical blade 7 through rotating in cell body 12 forms hindered settling.In this process, part fine flows through downflow weir 9 with lateral current becomes qualified products, rest materials sinks to bottom land, upwards carry by helical blade 7, arrive the material at screening charging aperture 6 places, in screening charging aperture 6 is packed drum sieve 3 into,, upwards carries material while sieving in sieve by sieve internal helical blades 4.The material that sees through sieve aperture becomes undersize through 11 discharges of undersize discharge gate, and the material of saturating sieve does not enter sand-returning channel 10 through oversize discharge gate 2.Sieve outer flushing water pipe 5 in drum sieve 3 rotary courses, material is sticking to be sieved and obstruction to eliminate to its bath.The granularity of undersize is controlled by screen size.
In actual applications, the overflow product of screw classifying section and the undersize of screening section can merge, and also can handle respectively.Therefore can obtain the product of two or three size fractionated.
