Description
Technical field
The present invention relates to diameter-verifying water medium sorting device, be particularly useful for the sorting of wide grade, multi-component masses by density.
Background technology
Gravity separation all is widely used in fields such as mining industry, agricultural, solid waste separation.For the gravity separation device that with water is medium, the terminal velocity of sorting component is the principal element of the decision efficiency of separation.The terminal velocity of particle is relevant with the granularity of particle, shape, density etc., and the factor that influences sorting is more, and in fact, this class device is difficult to realize that wide grade multi-component masses effectively separates by density.In order to improve the efficiency of separation, before sorting, need material is carried out narrow classification; Or after fragmentation makes epigranular, make it carry out sorting, and require bigger by the density contrast of sorting material by density contrast.Shape by the sorting component also has a significant impact the efficiency of separation, because actual sorting material is in granularity with differ greatly in shape, the terminal velocity of concentrate and tailings is often overlapped, having caused great majority is that the gravity separation device efficiency of separation of medium is low with water, can't realize the separation of taking as the leading factor with density.
Summary of the invention
The present invention is directed to the weak point in the prior art, provide a kind of simple in structure, can realize wide grade multi-component masses by density separation, and the high diameter-verifying water medium sorting device of the efficiency of separation.
The present invention is achieved by following technical proposals: it comprises a reducing bed body that is obliquely installed, be provided with a plurality of obstruct nets in the reducing bed body, its front portion is provided with the waterpower distributor, its top, rear portion is provided with the spice groove, the head of reducing bed body and the preceding bottom of obstruct net are equipped with discharging opening, reducing bed body has the circulating water chennel of accepting reducing bed body afterbody aqueous medium material, is provided with filter cloth in the circulating water chennel, and the outside is provided with the water pump with water suction spice groove.
The inclination angle that described reducing bed body is obliquely installed is 25～35 °; The a plurality of of apopore form with compressing into water pipe described waterpower distributor (4) by being furnished with upwards; Described circulating water chennel can be one, also can be two.Diameter-verifying water medium sorting device of the present invention, employing reducing body combines with inclined-plane stream and produces the speed change flow field, make particle in this flow field, be in speed change degree motion state all the time, difference according to the storeroom kinetic property, the separation that realization is taken as the leading factor with density can realize that wide grade multi-component masses is by the effective sorting of density.Combination and control by factors such as reducing body size, tapering, arrangement inclination angle, the middle structure that intercepts net and position, rate-of flows produce the speed change degree flow field that sorting material needs.Water pump can carry out rectification to MEDIA FLOW, makes fluid stable, can regulate its flow simultaneously.When fluid enters the reducing body sorting device that is the placement of certain inclination angle by distributor, axially and on the section all can produce corresponding speed change degree flow field, according to the kinetic property difference of specifically wanting sorting material, can regulate and the combined effect factor, optimize, select suitable flow pattern.With respect to the wet method gravity separation device that with the particles settling end speed is decisive factor, the diameter-verifying water medium sorting bed efficiency of separation is higher, and the sorting operating condition is wideer, and separation velocity is faster.Can realize of the effective sorting of wide grade multi-component masses by density.Efficiency of separation height of the present invention, simple to operate, energy consumption is little, compact conformation, medium circulation is used, and has a wide range of applications in agricultural production, mineral processing, solid waste sorting, separating substances recovery field.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1-spice groove, 2-reducing bed body, 3-intercept net, 4-waterpower distributor, 5-water pump, 6-discharging opening, 7-circulating water chennel, 8-filter cloth.
The specific embodiment
Below in conjunction with the embodiment in the accompanying drawing the present invention is further described:
Shown in the accompanying drawing, diameter-verifying water medium sorting device is the reducing bed body 2 that settle at certain inclination angle, is aided with spice groove 1, intercepts net 3, waterpower distributor 4, water pump 5, discharging opening 6, circulating water chennel 7, filter cloth 8 combine.About about 30 ° of the inclination angle that reducing bed body 2 is obliquely installed, be arranged at intervals with two in the reducing bed body 2 that is obliquely installed and intercept net 3, the leading section of reducing bed body 2 is provided with waterpower distributor 4, its top, rear portion is provided with spice groove 1, and a plurality of of apopore form with compressing into water pipe waterpower distributor 4 by being furnished with upwards.The head of reducing bed body 2 and obstruct net 3 preceding bottoms are equipped with discharging opening 6, become the circulating water chennel 7 that Lei 2 has, circulating water chennel 7 is provided with two, accept reducing bed body 2 afterbody aqueous medium materials for one, be provided with filter cloth 8 in this circulating water chennel 7, another tank is accepted filtering water, and this tank outside is provided with the water pump 5 with filtering water suction spice groove 1.Diameter-verifying water medium sorting device is based on that kinetic property difference between material particles realize to separate in assorting room.In speed change degree flow field, particle is made varying accelerated motion, and the material of different motion character can produce locational gap, utilizes suitable reducing sorting bed body and controls certain operating parameter, can realize that wide grade multi-component masses is by the effective sorting of density.Under same fluid state, low-density material has better kinetic property, axially and on vertical more significant motion change is being arranged all, finally along with medium is selected from the sorting unit top as light product, high-density component then can be deposited on the device inwall, and, will collect from material taking mouth as heavy product along the wall falling.
Embodiment one, 0.1～0.2m steel ball and two kinds of material mixt standards of 0.2～0.3m bead material are carried out sorting.Material is fed continuously by spice groove 1, earlier material is stirred by agitator, regulate parameters, select suitable operating condition, low-density bead is selected from sorting unit head discharging opening 6 with aqueous medium as light component; Highdensity steel ball obtains from two discharging openings 6 that intercept net 3 front lower places as heavy ends.The weight component efficiency of separation can reach 98.60%, and effect is remarkable.
Embodiment two, the discarded printed circuit boards broken material is carried out sorting, realize that broken back metallic product and the effective of nonmetal product separate.Earlier discarded object being broken into granularity is 0.074～1mm, material is fed continuously by spice groove 1, earlier material is stirred by agitator, regulate operating parameter, nonmetally select from sorting unit head discharging opening 6 as light component, metal obtains from two discharging openings 6 that intercept net 3 front lower places as heavy ends.The grade of metal concentrate can reach more than 94% in the concentrate, and the rate of recovery reaches 93.5% simultaneously, has realized effective recovery of valuable component more satisfactoryly.
