In the structure slipped with two-stage, bulky grain goldc grains flow to material-dividing groove with the ore pulp compared with flow velocity urgency, due between the stupefied item of grid not
Gap greater than 3 millimeters causes the gold sand of fine particle to stay on the sufficiently large plate slot of area；Greater than 3 millimeters less than 20 millis
The gold sand of rice stayed in front of in after on three sections of inclined-plane grid, simultaneously as the design of multiple row, multiple rows of bleeder so that from point
The mouth of a river flows to the subtleer goldc grains that each layer is risen as high as the banks respectively and all stays on the golden felt of each layer gold felt bed, realize first take it is small after take it is big
The present embodiment is related to a kind of capacity-increasing type classification savings and slips, and so-called increase-volume refers to expands under the premise of slowing down flow rate of pulp
Big ore pulp flows through the width in face, and so-called classification refers to shares multistage, multilayer chute for the ore pulp containing gold sand as much as possible
In, by ore pulp flow through chute area further spread come.
Referring to attached drawing 1 to attached drawing 5, specifically, it is by with hopper 1, setting that the capacity-increasing type classification savings in this example, which is slipped,
It is constituted in components such as the perpendicular support 3 of support channel steel 2, hopper of hopper bottom, infiltration pond 5, filter pools 4.Wherein, in order to adjust savings
Whole suitable operation state is slipped, is equipped with elevating mechanism 301 in the perpendicular support 3 of hopper；In practice, according to mining environment
It needs, elevating mechanism can select the structure type or pedestal and keyhole positioned-lifting device of pedestal 302 and hydraulic pressure lifting device 303
Structure type, however, which kind of structure type, the lifter in this example should all meet both can be to the bilateral that classification savings is slipped
It adjusts simultaneously, it can also the unilateral working condition requirement adjusted.
Hopper in this example is made of plate hopper 101, material-dividing groove 104；The tail end of plate hopper 101 therein passes through
Transition platform 105 is connected with the head end of material-dividing groove 104.It is at least provided on the slot bottom plate 103 of the plate hopper 101
Three sections of hollow frames 102 are respectively provided with a savings on each hollow frame and slip grid.Described savings slips grid reality in this example
On be to be constituted by grill frame 106, every stupefied item 107, in practice, the setting quantity that savings slips grid can also be more than three sections.This
It can be the metal strip of reinforcing rod or similar rib strip shaped every stupefied item in example.The concentration of the stupefied item of embodiment interval is equivalent to one
Sieve is opened, when the savings that the gentle ore pulp of the force and velocity of a current flows through each section slips grid, because by setting every the gap of stupefied item 107 to each other
To be not greater than 3 millimeters, the gold sand less than 3 millimeters divides water to enter golden felt bed to be deposited on golden felt with water by guiding device.
Material-dividing groove 104 in this example, by transition platform 105, transition platform bracket 108, it is preceding in after three sections of 109 structures of grid
At, wherein transition platform 105 is arranged on transition bench bracket 108, and transition bench bracket 108 is arranged in plate hopper 101 and sub-material
Between slot 104.Transition platform 105 can be adjusted to certain inclination in advance when slipping by the considerations of for water conservancy diversion, setting classification savings
The state of degree.Three sections of putting in order for grid are leading portion grid, middle section lattice after in front of being arranged on material-dividing groove 104 in this example
The quantity of grid, back segment grid, grid can also be added sequentially.Be designed in this way is because when flowing through the ore pulp continuation every stupefied item 107
When flowing to material-dividing groove 104, being tilted the effect of water conservancy diversion by transition platform 105 and be full of water by the spilling of plate hopper 101 is influenced,
Ore pulp at this time flows in both directions again: section grid flows before, during and after a direction is towards material-dividing groove 104, another
Direction is then towards the flowing of guiding device 8 that material-dividing groove 104 is layered 7 direction of water outlet.At this point, due to three on material-dividing groove 104
It is also to constitute by grill frame, every stupefied item that section, which has each grid of inclined ramp, and stupefied arranging density of every section of grid
It is that leading portion is greater than middle section, middle-end is greater than latter end, so, flow to the larger-diameter goldc grains that the ore pulp in material-dividing groove mixes inside it
It can be remained in respectively on leading portion grid, middle section grid and back segment grid.And the ore pulp for flowing to layering water outlet direction then passes through
The guiding device 8 for being located at layering water outlet 7 is transported to the gold of 71 lower section of multilayer bleeder being made of golden felt bed 6, golden felt 61
On grain recyclable device.At this point, being assigned to the ore pulp in each layer gold felt bed after seeping water since effect is led in dividing for guiding device 8
All fine particles gold sands stayed on golden felt 61 all can be received to the greatest extent nothing left.
Above embodiments disclose substantive distinguishing features of the invention: by General layout Plan of the invention, receiving gold sand to the greatest extent
Process can be divided into two stages.The implementation steps of first stage are that ore pulp is acted on by the delay of plate hopper 101, according to flat
The structure of plate slot, flow rate of pulp are reduced paragraph by paragraph, but opposite ore pulp inlet ore pulp flows through the area on plate slot simultaneously
It extends；Under the premise of the slow area of flow velocity is big, the gap between stupefied item of grid is slipped due to having designed savings, this
Most of particulate gold sand in Shi Liujing grid (being equivalent to screen) ore pulp will all remain in savings and slip；Simultaneously as leading
Stream device divides water guide functions, is also the continuity in this stage in terms of continuing to collect fine particles gold sand, this continuation phase
Effect is still further to extend fluvial processes, the unrestrained area of flowing water leaching is magnified.For example, being flowed to point from plate hopper
The ore pulp of layer water outlet is further shunted by guiding device, i.e. by least two rows of bleeders arranged side by side, the water outlet of each column
72 at least have the width of three layers, every layer water outlet not only but also are less than the bedside of corresponding golden felt bed.At this point, water is with same
Flow velocity to the water that the corresponding golden felt bed of each water outlet is flowed into be also the same.That is, what the water shunted entered
The golden felt bed 6 being layering, and the area of each golden felt bed is equally big, so flow into the water water of golden felt bed as many,
This is equivalent to and has expanded the work surface that golden felt bed 6 retains gold sand as far as possible；So far, flow velocity, the stream of each layer gold felt bed water are flowed into
Amount is impartial, so solving the problems, such as that fluvial processes extend, the unrestrained area of flowing water leaching expands, particulate gold sand is received to the greatest extent at once.
Described work surface is come out by actuarial and practice summary in this example: the work of relatively common single chute 24m2
Industry area, capacity-increasing type of the present invention classification savings are slipped, the folded developed area for falling golden felt bed therein can for 3 × 24m2=
The m2 of the m2 of 72 m2 or 6 × 24m2=144 or 9 × 24m2=216 or 12 × 24m2=288m2, the multiplier in each formula indicate
Be golden felt bed number.Furthermore, it is contemplated that gold sand is received to the greatest extent, seep water convenient actual requirement, it can when golden felt bed is set
The folded head of a bed for falling golden felt bed is uniformly higher than the tailstock other end towards one end of bleeder by it using pond of seeping water as object of reference
Setting makes bed body have certain tilt angle.
The implementation steps of second stage are to realize that the collection of bulky grain gold sand is acted by material-dividing groove: as preceding institute
It states, flowing through material-dividing groove ore pulp is by transition platform to letting out under each section of grid of material-dividing groove, since each section of grid all has centainly
Inclination angle, the setting quantity of grid can also be greater than three sections, under let out big grain gold sand in ore pulp and slag can all take advantage of a situation and under.
Due to the density of every section of grid stupefied item arrangement be greater than middle section according to leading portion, middle section is greater than the pattern of latter end and arranges, so
The flow rate of pulp let out under the big grain gold sand that each grid is retained in the case where constant can be stayed in slag because each partial size is different
On the different grid of stupefied rod density；Even if the phenomenon that ore pulp is sprung up is let out under, also due to stupefied rod density is not on each section of grid
With water flow natural layering is made, equally it can stay small clear water that big principle is stayed to keep here every the particle gold sand on stupefied item according to muddy water, that is,
The purpose that the goldc grains and slag for completing this stage " big " are recycled simultaneously.
