Description

Technical Field

[0001] The utility model relates to the technical field of wet drainage of fine-grained tailings, in particular to a partition for clarifying water areas in a wet drainage tailings pond. Background Art

[0002] Wet-drain upstream tailings dam is widely used. Factors affecting the deposition characteristics of wet-drain metal tailings include particle size, flow velocity, concentration and flow rate.

[0003] (1) Granularity

[0004] Particles with a diameter greater than 0.037mm are sedimentary materials, which are deposited quickly in moving water and are the main part of alluvial flats; particles with a diameter of 0.037-0.019mm are bedload materials, which are deposited slowly in moving water and are the main part of alluvial flats; particles with a diameter of 0.019-0.005mm are mobile materials, which are deposited very slowly in clean water and are the main part of the sludge deposition area; particles with a diameter less than 0.005mm are suspended materials, which are difficult to deposit in still water and form suspended solids in water. Figure 1 The figure shows a schematic diagram of tailings deposition within a tailings pond. In the figure, A is the initial dam, B is the original tailings, C is the sedimentation beach, D is the downstream sedimentation beach, E is the suspended sludge area, and 6 is the drainage well.

[0005] (2) Flow rate: When the tailings particle size, concentration and other conditions remain unchanged, a low flow rate will make it easier to deposit, while a high flow rate will make it less likely to deposit;

[0006] (3) Concentration: When the tailings particle size remains unchanged, the higher the concentration, the faster the sedimentation;

[0007] (4) Flow rate: When factors such as concentration and particle size remain unchanged, the smaller the flow rate, the faster the deposition;

[0008] (5) Chemicals: Certain mineral processing chemicals and the pH value of tailings water will affect the sedimentation of tailings. For example, water glass makes tailings difficult to sediment. In order to accelerate the sedimentation of fine particles, certain chemical agents such as CaCl2, HCl and F691 can be added.

[0009] In order to ensure the flood control capacity of the tailings pond and the water depth of the clarified water area, especially when the storage object is fine-grained tailings, the design generally requires the formulation of a reasonable discharge concentration and the use of multi-tube small flow discharge methods to ensure the concentration of the tailings sediment beach.

[0010] According to the above-mentioned tailings deposition characteristics (2), when conditions such as particle size and concentration remain unchanged, sedimentation is easy when the flow rate is low, and difficult when the flow rate is high. During the actual tailings discharge operation and maintenance management stage, tailings pond managers often slow down the flow rate of tailings water by adding iron sheet partitions. That is, iron sheet partitions are placed in the flow path of tailings water through floating bridges to extend the flow distance and slow down the flow rate. As the tailings rise, the iron sheet is lifted at regular intervals to exceed the restricted water level. This method of manually lifting the iron sheet at regular intervals is inefficient, and the iron sheet does not have a filtering function. Utility Model Content

[0011] The utility model aims to provide a wet tailings pond for clarifying water area partition and improving efficiency.

[0012] The technical solution of the utility model is: a wet-drainage tailings pond clarified water area partition, including floats, connecting ropes and geotextiles, characterized in that it also includes counterweight stones, the number of the floats is multiple, the connecting ropes connect the floats in sequence, the geotextile is vertically arranged, and the top of the geotextile is connected to the connecting ropes, the bottom of the geotextile is provided with a closed cavity, and the counterweight stones are arranged in the cavity.

[0013] In the above scheme, the original iron sheet partition is optimized into a structure of a float hanging geotextile. As the tailings rise in the later stage and the water level of the tailings pond rises, the float drives the geotextile to float up automatically without manual operation, and automatically realizes the isolation function to the next water level elevation, thereby improving efficiency and simplifying and convenient operation and maintenance.

[0014] Preferably, the wet tailings pond clarified water area partition further includes a skeleton connected to the lower ends of two or more floats.

[0015] Preferably, the skeleton includes at least two vertical ribs and multiple transverse ribs, at least two of the vertical ribs are connected to the floats in a one-to-one correspondence, and the multiple transverse ribs are vertically connected to the at least two vertical ribs.

[0016] Preferably, a sandwich layer is provided in the geotextile, and the skeleton is placed in the sandwich layer.

[0017] Preferably, the float is a float with two ears, and the connecting rope is connected to the two ears of the float.

[0018] Preferably, the connecting rope is galvanized iron wire.

[0019] Preferably, the geotextile is a short-length geotextile.

[0020] Preferably, the counterweight stone is crushed stone with a particle size of 2-5 cm.

[0021] Compared with the related art, the beneficial effects of the present invention are:

[0022] 1. This utility model optimizes the original iron sheet partition into a flexible partition structure with a float hanging on the geotextile, which can not only achieve the purpose of slowing down the flow rate of tailings water, but also increase the area and depth of the clarified water area. The geotextile has a reverse filtration function, which can maintain the seepage pressure balance when the water pressure before and after the partition is high, and is easy to operate and maintain.

[0023] 2. Add counterweight stones to the bottom of the geotextile so that the bottom of the geotextile can sink into the silt tail clay and prevent the geotextile from floating around.

[0024] 3. The skeleton is set inside the geotextile to improve the rigidity of the geotextile. In the valley with fast water flow and high wind speed, the skeleton plays a better anchoring role for the geotextile;

[0025] 4. The utility model optimizes the original iron sheet partition into a structure with a float hanging on the geotextile. As the tailings rise in the later stage and the water level of the tailings pond rises, the float drives the geotextile to float up automatically without manual operation, and automatically realizes the isolation effect to the next water level elevation, thereby improving efficiency and making operation and maintenance simple and convenient.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0034] Example 1

[0035] like Figure 2 、 Figure 3 As shown, the present embodiment provides a wet-drain tailings pond clarified water area partition comprising a float 1, a connecting rope 2, a geotextile 3 and a counterweight stone 4.

[0036] There are multiple buoys 1, which are double-ear buoys with a diameter of 0.3m. They are purchased parts. One side of the buoy is provided with an ear plate, and the ear plate is provided with double holes. When placed on the water surface, the ear plate faces upward.

[0037] The connecting rope 2 is a No. 8 galvanized iron wire, which connects the plurality of floating balls 1 in series. The number of floating balls 1 is appropriately selected according to the size of the underwater sediment beach area of the tailings pond.

[0038] The geotextile 3 is a short-strength geotextile with a strength of 15 kN / m. The geotextile 3 is double-wrapped into a bag with a sandwich layer formed inside. The bottom is sewn with horizontal cloth 31 and silk thread to form a closed cavity 32, and the counterweight stone 4 is placed in the cavity 32.

[0039] The counterweight stone 4 is a crushed stone with a particle size of 2-5 cm, so that the bottom of the geotextile 3 can sink into the silty tailing clay.

[0040] As the tailings rise in the later stage, the tailings water level also rises. After the water level rises, the float 1 and the geotextile 3 on it float up by themselves, thereby achieving the next water level elevation isolation function.

[0041] Example 2

[0042] like Figure 4 As shown, the first embodiment is repeated, except that, if the water depth is deep or the valley environment is poor (e.g., strong wind), the wet tailings pond clarified water area partition further includes a frame 5. The frame 5 is placed in the interlayer of the geotextile 3 and is located above the cavity 32.

[0043] The skeleton 5 includes vertical bars 51 and multiple transverse bars 52. The number of vertical bars 51 is determined based on the area where the geotextile 3 needs to be anchored. Each vertical bar 51 corresponds to each buoy 1 and is connected to the connecting cable 2. Multiple transverse bars 52 are perpendicularly connected to at least two of the vertical bars 51. The vertical bars 51 and transverse bars 52 are connected in a crisscross pattern to form a grid. Both the vertical bars 51 and transverse bars 52 are No. 8 structural steel bars.

[0044] The skeleton 5 is determined based on the buoyancy and number of buoys 1, their spacing, the counterweights 4, and on-site buoyancy tests. The skeleton 5 addresses the issue of partitions drifting and moving away from their intended location in valleys with fast currents and strong winds. The skeleton also serves as an anchor.

[0045] Example 3

[0046] The wet tailings pond clarification water area partition provided by the utility model can be arranged according to the water inlet facilities of the drainage system. Figure 5 As shown, in this embodiment, the water inlet facility is a drainage well 6, and the partition is in a ring shape surrounding the drainage well 6.

[0047] Example 4

[0048] like Figure 6 As shown, in this embodiment, the water inlet facility is a chute 7, and the partition is a strip perpendicular to the extending direction of the chute 7.

[0049] The wet-drain tailings pond clarified water partition provided by the utility model is applied to the underwater sediment beach area of the tailings pond, and adopts a partition form of floats hanging geotextile belts to replace traditional partitions such as iron sheets or wooden boards, slowing down the flow rate of tailings water, increasing the slope of the underwater sediment beach, and increasing the depth of the clarified water area, indirectly saving the cost of water treatment agents and creating certain economic benefits.
