Description
(1) technical field: the utility model relates to the classification of the thinner solid particle of the equipment that the solid particle in the various slurries is carried out classification, particularly granularity.
(2) background technology: at present, at the grader that the solid particle in the various slurries is carried out classification of industry extensive uses such as metallurgy, chemical industry, ore dressing, mainly containing needs power, as spiral classifier and hydrocyclone; Need not power, utilize the free settling of solid particle to carry out classification, as swash plate groove and cone classifier.Need the grader energy consumption height of power, equipment attrition is fast, and spiral classifier can't be used for fine grain classification.The swash plate groove has increased settling area owing to be provided with some inclination deflectors in the groove, so the classification efficiency height, and simple in structure.But, the base plate gradient of this swash plate groove is subjected to the restriction of its length, general all about 15-30 °, thereby cause the coarse-grained material that is deposited on the base plate mobile poor, the material clogging usually appears, not only the reduction classification efficiency, and equipment can not normally be moved, so its application is restricted.The advantage of cone classifier is, the gradient of conical walls is bigger, and usually more than 45 °, therefore settled coarse-grained material is smooth and easy from the bottom discharging.But its settling area is little, and particularly slurry directly adds from the circular cone center, and the impulsive force of generation has produced destruction to the free settling of solid particle, and classification efficiency is low.And, being subjected to the restriction of device structure, its annular overflow trough gradient generally only has 0.5-1%, easily produces the material deposition, and often cleaning has increased operating cost and labour intensity.
(3) summary of the invention: the utility model is to stop up because of bottom coarse-grained material discharge in order to solve existing swash plate groove, reduces classification efficiency, influences the problem of the normal operation of equipment; The problem that the cone classifier classification efficiency is low provides a kind of classification efficiency height, and the discharging of coarse-grained material underflow is smooth and easy, simple in structure, need not power, reliable swash plate-cone classifier.
The utility model is for solving the above-mentioned technical problem that prior art exists, realize goal of the invention, the technical scheme that adopts is: the top of grader is that the level cross-sectionn is square inclined plate sedimentation groove, inclination deflector on the two opposite side walls that some two ends are separately fixed at it is set in the groove of inclined plate sedimentation groove equidistantly, the bottom surface of side overflow mouth is on same horizontal plane on the upper end of inclination deflector and the inclined plate sedimentation groove effluent head end wall, the outside of side overflow mouth is an overflow launder, the bottom is that the level cross-sectionn is circular one or more inverted cone grooves, the square inclined plate sedimentation groove on top is connected and composition swash plate-cone classifier with vertical the cutting mutually of one or more inverted cone grooves of bottom, two adjacent inverted cone groove levels of a plurality of inverted cone grooves are cut connection mutually, the sidewall that is positioned at the inverted cone groove of material feeding end extends upwardly to the top of inclined plate sedimentation groove, and cut the end wall that forms material feeding end mutually with it, make the inclination deflector identical with the intersecting lines tilt of vertical plane of symmetry of inclined plate sedimentation groove with this material feeding end end wall, after each several part cuts connection mutually, distance (lateral separation) between the intersection point that adjacent two inverted cone grooves cut mutually equals the cell body width of inclined plate sedimentation groove, cell body length maximum horizontal range and that equal the inclined plate sedimentation groove between inclined plate sedimentation groove and vertical each adjacent intersection point that the inverted cone groove cuts mutually, on the material feeding end end wall, have a horizontal material inlet, the bottom surface of material inlet is a little less than the lower end horizontal plane of inclination deflector, its end face then is lower than the upper end horizontal plane of inclination deflector, in material feeding end end wall arranged outside feeder trough is arranged, the wedged bottom of feeder trough and material feeding end end wall cut the bottom surface in material inlet mutually, and the bottom of inverted cone groove is provided with apex.
The level cross-sectionn of the utility model inverted cone groove also can be ellipse, on same horizontal plane, and the parallel sidewalls of long axis of ellipse or minor axis and inclined plate sedimentation groove.
Advantage of the present utility model is the inclined plate sedimentation groove that adopt on top, has high classification efficiency, and the underflow that the circular cone of bottom settles down to the inclined plate sedimentation groove concentrates and classification again, so classification efficiency is higher than the swash plate groove classification efficiency of prior art.The circular cone sidewall gradient is big in addition, and the discharging of underflow coarse-grained material is smooth and easy, and therefore stable, fault rate is low.It had both developed existing swash plate groove and cone classifier advantage separately, overcome the technical problem that they exist separately again, and classification efficiency was more than they height.It also has simple in structure, and slurry can flow automatically when feeding grader, and operating cost is almost nil, advantages such as remarkable in economical benefits.Be the novel classifying equipoment that a kind of energy substitutes existing swash plate groove, cone classifier, hydrocyclone, be specially adapted to the classification of fine, have good popularization and application prospect.
