Abstract
The utility model discloses an activated carbon filtering device, which comprises an external framework and an internal filter medium. The internal filter medium is in a five-layer structure consisting of a filter cloth layer or a grass layer, a coarse fraction activated carbon layer, a medium fraction activated carbon layer, a fine fraction activated carbon layer and a rubble layer in sequence from bottom to top. The activated carbon filtering device has the advantages of simple structure, low requirements for the material quality, easiness in manufacturing, convenience in use, low cost and easiness in fabrication on site, is applied in a gold mine to effectively filter and recover gold loading activated carbon powder in a state of suspension in a heap leaching barren solution, and is used for further absorbing micro gold residuals in the barren solution simultaneously so that the problem of double loss of gold and activated carbon is solved; therefore, purposes of making full use of gold resources and improving productivity effects of a mine are achieved.
Description
Technical field
The utility model relates to filter, especially a kind of active carbon filtering device.
Background technology
The dump leaching process that gold mine adopts is generally with the gold in the expensive liquid of charcoal absorption; Yet there is an outstanding problem in this technology, that is: activated carbon block can form a large amount of active gold-carrying carbon powder in adsorption process; After they are pumped and spray into the ore deposit heap; To forever be trapped in the heap of ore deposit, and can continue to adsorb the gold in the leachate, cause the dual loss of gold and active carbon.For reducing the gold loss; Many gold mines carry out preliminary treatment its part corner angle are worn and torn and remove powdered carbon to activated carbon block earlier before absorption; Although this method to a certain degree can reduce the activated carbon powder amount; But in the charcoal adsorption process, charcoal interblock collision friction each other still can produce a large amount of activated carbon powders, and the problem of gold and the dual loss of active carbon is not solved at all.Than valid approach is to utilize active carbon filtering device that the active gold-carrying carbon powder in the dump leaching lean solution is filtered and reclaims., commercial goods active carbon filter complex structure, material require height, use difficulty (lean solution needs pumping), price is higher, transportation is inconvenient (ratio of height to diameter is big) etc., can not satisfy the actual needs that gold mine is produced.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure, material and requires low, easy to manufacture, easy to use, with low cost, as to be easy to field fabrication active carbon filtering device.
Adopt following technical scheme for solving the problems of the technologies described above: active carbon filtering device; Comprise external frame and inner filtration medium; Inner filtration medium is a five-layer structure, is filter layer of cloth or straw or like vegetable layer, coarse fraction active carbon layer, middle grade active carbon layer, fine fraction active carbon layer and metalling from the bottom up successively.
The bottom of this device and top-side are respectively arranged with liquid outlet and inlet, and support has been constructed in the liquid outlet top, and filter layer of cloth or straw or like vegetable layer are laid on the support.
External frame adopts the concrete structure fabrication, and its cross section is circle or polygon, and its vertical section is the straight barrel-shaped or straight barrel-shaped lower hopper shape in top; Support is wooden structures or adopts concrete for making.
Coarse fraction active carbon layer, middle grade active carbon layer, fine fraction active carbon layer and metalling are that 10～50mm active carbon, 1～10mm active carbon, 0～1mm active carbon and 10～100mm rubble are formed by granularity respectively.
The active carbon filtering device of the utility model adopts the inner filtration medium of five-layer structure, and undermost filter layer of cloth or straw or like vegetable layer can prevent the loss of active gold-carrying carbon; Both can further adsorb micro-gold residual in the lean solution by thin to the thick active carbon layer of laying, but the active gold-carrying carbon powder that also suspends in the filtered and recycled lean solution simultaneously; The rubble of top layer then plays cushioning effect, prevents that feed liquor from directly washing away the active carbon under it, destroys the structure of filter medium, improves filter effect.The utility model is low to the material requirement, making is simple, be convenient to the mine field fabrication; Be applied to gold mine production and can effectively filter and reclaim the active gold-carrying carbon powder in the dump leaching lean solution; Solve the problem of gold and the dual loss of active carbon, reach the purpose that makes full use of gold resource and raising mine productivity effect.
Description of drawings
Fig. 1 is the structural representation of the utility model active carbon filtering device.
Fig. 2 is the vertical view of Fig. 1 active carbon filtering device.
Among the figure: 1 external frame, 2 cogongrass layers, 3 coarse fraction active carbon layers, grade active carbon layer in 4,5 fine fraction active carbon layers, 6 metallings, 7 liquid outlets, 8 inlets, 9 supports.
The specific embodiment
As depicted in figs. 1 and 2; The active carbon filtering device of the utility model; Comprise external frame 1 and inner filtration medium; Inner filtration medium is a five-layer structure; Be that cogongrass layer 2 (100mm is thick), coarse fraction active carbon layer 3 (200mm is thick), middle grade active carbon layer 4 (400mm is thick), fine fraction active carbon layer 5 (200mm is thick) and metalling 6 (300mm) are thick from the bottom up successively, wherein, back four layers is that 10～50mm active carbon, 1～10mm active carbon, 0～1mm active carbon and 10～100mm rubble are formed by granularity respectively; The bottom of this device and top-side are respectively arranged with liquid outlet 7 and inlet 8, and support 9 has been constructed in liquid outlet 7 tops, and filter layer of cloth or straw or like vegetable layer 2 are laid on the support 9; External frame 1 adopts concrete structure fabrication (specification look the mine production scale and decide), is cubic column type (the high 1x1x1.5m of the wide x of long x
3, its cross section is a square, its vertical section is barrel-shaped for directly; Support 9 is wooden structures or adopts concrete for making.
Application example
At the Ba Wang of our unit gold mine, the lean solution after process charcoal absorption case once adsorbs contains golden 0.33 μ g/mL, contains microactuator suspension particulate active gold-carrying carbon powder 3.0g/L.When lean solution flows into above-mentioned active carbon filtering device certainly by inlet, after the filtration and second adsorption of filter medium, the filtrating of flowing out from liquid outlet contains golden 0.048 μ g/mL, contains microactuator suspension particulate active gold-carrying carbon powder 0.56g/L.Test shows that the utility model effect is remarkable, and its second adsorption and filtered and recycled rate to gold and activated carbon powder reaches 85% and 81% respectively.
