The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
In Fig. 1, one first reflecting plate 1 downward-sloping placement, its tilt adjustable.Be granular material and fall on first reflecting plate 1, and flow downward, form grain flow 2 along first reflecting plate 1 by conveyer belt or running roller (not shown).Because the difference of material particular diameter size and the difference of consequent momentum, granular material is preliminary segregation classification on first reflecting plate 1, make bulky grain in the granular material in the enrichment of the upper strata of grain flow 2 and granule in lower floor's enrichment of grain flow 2.Fig. 2 is the enlarged diagram of the A position 4 of Fig. 1, can be clear that the classification status of grain flow 2.
In order further to strengthen the segregation grading effect of granular material, the utility model utilizes a secondary segregation device 3 to come granular material is carried out the secondary segregation.This secondary segregation device 3 is positioned at the below of first reflecting plate 1 and is on the motion path of grain flow 2.
This secondary segregation device 3 has a upper surface, is used to carry the granule materials that falls with grain flow 2, and the width of its width and first reflecting plate 1 is identical or outline is wideer.Utilize the segregation effect that banking process produced of granule materials on secondary segregation device 3, also utilize the difference of the material particular diameter size in the grain flow 2 and the difference of consequent momentum and speed, make from the 1 fallen existing to a certain degree grain flow 2 further segregations of segregation of first reflecting plate.Like this, most bulky grain drops on the right of the upper surface of secondary segregation device 3 in the grain flow 2, and most granule drops on the left side of the upper surface of secondary segregation device 3 in the grain flow 2.This point can be seen clearlyer in Fig. 3 and Fig. 4, and wherein, Fig. 3 is the enlarged diagram of the B position 5 among Fig. 1, and Fig. 4 is the enlarged diagram of the C position 6 among Fig. 1.
Along with the accumulation of granule materials on the secondary segregation device 3, bulky grain mainly falls from the right side of secondary segregation device 3, and granule mainly falls from the left side of secondary segregation device 3.So just realized secondary classification to granule materials.In order to prevent that material from falling from the both sides on secondary segregation device 3 widths, can flanging (not shown) upwards be set in these both sides.
Lifter 7 is positioned at secondary segregation device 3 belows, can regulate the height of secondary segregation device 3.According to concrete application, secondary segregation device 3 also can be provided with pulley or guide rail, so that adjust its horizontal level.
The upper surface of secondary segregation device 3 can be a plane, and at this moment, secondary segregation device 3 can be a surface plate, as shown in Figure 1.The upper surface of secondary segregation device 3 also can be convex surface, as shown in Figure 6 the shape of three kinds of secondary segregation devices 3.
As shown in Figure 7, the upper surface of secondary segregation device 3 can also be the umbrella face, and at this moment, secondary segregation device 3 can be made up of two surface plates that connect by hinge or alternate manner, and the location arrangements of these two surface plates becomes umbrella.And, the tilt adjustable of two surface plates of formation secondary segregation device 3.Material to different qualities, can be by regulating horizontal and vertical position and the angle of two surface plates and the segregation that length is strengthened large and small granule materials of secondary segregation device 3, bulky grain is mainly fallen from the right side, and granule falls from the left side, thereby arrive the grading requirement of producing.
In an application of grading plant of the present utility model, as shown in Figure 1, the granule materials on the secondary segregation device 3 has been fallen on the conveyer belt 9.Regulate the direction of motion of conveyer belt, can make the granular solid matter material fall on the conveyer belt after, on demand granule size distributes on bed depth, to satisfy the requirement of various processes.For example, in Fig. 1, conveyer belt 9 motion counterclockwise, bulky grain on the secondary segregation device 3 is at first fallen on the conveyer belt 9 from its right side, moves to the left side of secondary segregation device 3 then with driving-belt 9, like this, granule on the secondary segregation device 3 is fallen above oarse-grained on the conveyer belt 9 from its left side, granule is in last layer distributed descending thereby form bulky grain, and this sees the most clearly in Fig. 5, and Fig. 5 is the schematic diagram that obtains after D position among Fig. 1 11 is amplified.This layer distributed of similar Fig. 5 is very useful in sinter mixture segregation distribution technology.
In above-mentioned application, as shown in Figure 1 and Figure 4, consider that the left side of secondary segregation device 3 also has a spot of bulky grain, can also be provided with a reflecting plate this moment in the left side of secondary segregation device 3 in addition.Show in detail this situation in Fig. 8, the angle of inclination of second reflecting plate 10 and first reflecting plate 1 (not shown among Fig. 8) are basic identical, and second reflecting plate 10 is positioned at the left side of secondary segregation device 3, the most of short grained side of the device of secondary segregation just 3 carryings.10 pairs of material segregations once more that fall from secondary segregation device 3 left sides of second reflecting plate are fallen on the conveyer belt bulky grain wherein earlier, and this will further improve large and small particle distribution effect from top to bottom on the vertical conveyors direction.
In the another one of grading plant of the present utility model was used, as shown in Figure 7, the granule materials on the secondary segregation device 3 had been fallen respectively on two conveyer belts 9, so just can collect respectively the size particles in the granule materials.This need carry out in the technology of two-stage screening to granule materials at some is very useful.
