Description

A tailings sewage treatment tank

technical field

The utility model relates to the field of mining sewage treatment, in particular to a tailings sewage treatment tank.

Background technique

In the prior art, tailings refer to waste residues and slags discharged by mining enterprises after mineral processing, and are mostly discharged in the form of mud, which accumulates over time to form tailings pools. The tailings pond covers a large area and is a great safety hazard. In addition, the water from the tailings, which is rich in mineral processing chemicals in the tailings pond, seeps into the ground, causing great pollution to the environment and groundwater. Therefore, the treatment of ore dressing tailings is a major problem facing mine producers.

And tailings water treatment technology: tailings pond is a large-volume sedimentation-storage pond, which can be set on valleys, slopes, river beaches or flat land by using the terrain and surrounded by dikes and dams. Drainage wells and drainpipes are set in the pool, or drains are set up along the edge, and the tailings water is clarified and purified in the pool and then overflows and discharged. Suspended solids in tailings water are deposited at the bottom of the pond for storage. The waste water stays in the pond for at least one day and night. This method can effectively remove suspended solids in wastewater, and the content of heavy metals and flotation agents is also reduced. The longer the residence time, the better the treatment effect. Tailings pond overflow water can be recycled. Gravity separation, magnetic separation and simple flotation of single metal ore do not require high water quality, and the water recycling rate can reach 80%, or no drainage at all. However, with the change of ore ore, the proportion of fine ore and oxidized ore increases, and the backwater of the concentration pool of iron ore tailings becomes turbid. , Seriously affect the quality of iron concentrate and titanium concentrate. Therefore, the tailings water treatment system needs to be rebuilt.

Utility model content

For solving above-mentioned technical purpose, the technical scheme that the utility model adopts is as follows:

A tailings sewage treatment tank, characterized in that it includes a columnar tank body, a stirring tank and a sedimentation tank arranged in the tank body, and a stirring device arranged on the tank body; the stirring device includes a stirring paddle, which controls the rotation of the stirring paddle The output motor and the detachable paddle arranged on the stirring paddle; the middle part of the paddle is provided with a paddle through hole and a plurality of pin holes are provided on the circumference of the via hole, and the paddle is provided with a plug hole Adapted limit fixing holes; the inner wall of the tank is equipped with a plurality of flocculant feeding pipes uniformly distributed along the central axis of the tank body, and the bottom of each feeding pipe is provided with a tapered discharge port, and in the middle of the tapered discharge port A leak hole is opened; a water outlet is arranged on the wall of the tank body, and a water inlet is arranged on the top of the tank body.

Further, the water outlet is connected with a filter press.

Further, a needle valve is provided at the leakage hole.

Further, multiple rows of paddles are connected to the stirring paddle, and each paddle is fixed through a screw through a pin hole and a limit fixing hole.

Further, the tails of the flocculant feeding pipes are provided with reversible sealing caps.

Further, a plurality of reinforcing support plates are arranged on the outer side of the tank body.

The beneficial effects of the utility model are: different from the situation of the prior art, the utility model can effectively treat the tailings sewage, and the sewage can be recycled and reused by adding flocculants, saving economic costs and avoiding environmental pollution.

Description of drawings

Fig. 1 is a structural schematic diagram of a tailings sewage treatment tank provided by the utility model.

Marks in the figure: 1 is the tank body, 2 is the settling tank, 3 is the stirring paddle, 4 is the feeding pipe, 5 is the water inlet, 6 is the output motor, 7 is the water outlet, 8 is the reinforced support plate, and 9 is the paddle.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in Figure 1, a kind of tailings sewage treatment tank comprises a columnar tank body 1, a stirring tank and a settling tank 2 arranged in the tank body 1, and a stirring device arranged on the tank body 1; the stirring device includes Stirrer 3, the output motor 6 that controls the rotation of the stirrer 3, and the detachable paddle 9 that is arranged on the stirrer 3; A pin hole, and a limit fixing hole adapted to the pin hole is provided on the stirring paddle 3; a plurality of flocculant feeding pipes 4 are evenly distributed along the central axis of the tank body 1 on the inner wall of the tank body 1, and each feeding tube 4 is arranged on the inner wall of the tank body 1. The bottom of the pipe 4 is provided with a tapered outlet, and a leak hole is opened in the middle of the tapered outlet; the wall of the tank body 1 is provided with a water outlet 7, and the top of the tank body 1 is provided with a water inlet 5. The water outlet 7 is connected with a filter press. A needle valve is arranged at the leakage hole. A plurality of rows of paddles 9 are connected to the stirring paddle 3, and each paddle 9 is fixed through a screw through a pin hole and a limit fixing hole. The end of the flocculant feeding pipe 4 is provided with a reversible sealing cover. A plurality of reinforcing support plates 8 are arranged on the outside of the tank body 1 .

In actual use, the tailings sewage is introduced from the water inlet 5, and the new sewage and the undischarged water in the original treatment tank are fully mixed by the stirring device. Thereafter, the needle valve at the bottom of the feed pipe 4 is opened, and the flocculant is continuously fed into the sewage treatment tank. The flocculant is an anionic polyacrylamide product with a molecular weight of 1000-1400. Anionic polyacrylamide is a water-soluble high-molecular polymer. Because its molecular chain contains a certain number of polar groups, it can absorb solid particles suspended in water to bridge between particles or agglomerate particles through charge neutralization. large flocs. Therefore, anionic polyacrylamide can accelerate the settling of particles in the suspension, and has a very obvious effect of accelerating solution clarification and promoting filtration. For suspended particles, coarse, high concentration, positively charged particles, and neutral or alkaline sewage, the molecular chain contains a certain amount of polar groups that can absorb solid particles suspended in water. The selection of polyacrylamide reagents and the recycling of water in sewage settlement mainly use anionic polyacrylamide. Because the fineness of minerals is relatively fine, the content of slime is relatively high. Anions have the characteristics of fast settling speed and relatively clear water quality. It can effectively adsorb and clarify fine substances, and finally connect the water outlet 7 to a filter press for separation, and the clarified water can be recycled and the particulate matter can be recovered.

The above is only an embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process conversion made by using the utility model specification and accompanying drawings, or directly or indirectly used in other related All technical fields are all included in the scope of patent protection of the utility model in the same way.
