Embodiment 1

[0021] Such as Figure 2 to Figure 4 As shown, this embodiment is composed of a reaction zone 1, a precipitation zone 2 and an oil removal zone 3. In the reaction zone 1 of this embodiment, the folded plate structure is canceled, and a mechanical stirring structure is adopted, and the top center of the reaction zone is provided with The stirring motor 101, the stirring motor 101 drives the stirring blade 103 at the bottom of the stirring shaft 102 to rotate, and stirs and mixes the sewage and the flocculation agent entering the reaction zone 1 from the water inlet 104, thereby accelerating the mixing reaction of the agent and the sewage, and reducing the reaction time. The reaction time of mechanical stirring generally only needs 5-10 minutes.

[0022] Between the reaction zone 1 and the precipitation zone 2, a static degreasing zone 3 is provided. The static degreasing zone 3 is divided into two independent left and right chambers by a middle partition. The inverted U-shaped ...

Embodiment 2

[0025] Figure 5 to Figure 7 It is another embodiment of the present invention, consisting of a reaction zone 1, a precipitation zone 2 and an oil removal zone 4, the reaction zone 1 and the precipitation zone 2 are adjacent to each other, and the reaction zone 1 and the precipitation zone 2 have the same structure as in the first embodiment The present embodiment is provided with dissolved air degreasing area 4 in the back road of precipitation area 2, and the bottom of dissolved air degreasing area 4 is provided with dissolved air water distribution pipe 403, and the top is provided with oil scraper 401, and the trolley bottom that is driven by motor An oil scraper is provided, and an oil outlet pipe 404 is arranged near the level of the oil scraper where the tank body is located in the oil removal area, and a water outlet pipe 402 is arranged on the upper part of the tank body.

[0026] In actual operation, the chemical and sewage in the reaction zone 1 are fully mixed and ...

Abstract

The invention discloses a high-efficiency deposition device for mines. The high-efficiency deposition device for mines comprises a reaction zone, a deposition zone and an oil removal zone, wherein the reaction zone, the deposition zone and the oil removal zone are arrange in series. The top of the reaction zone is provided with an agitator motor. The agitator motor drives agitating vanes located at a lower part of an agitating shaft to rotate. A double-layer inclined plate (pipe) filling material is arranged in the deposition zone. A lower inclined plate and an upper inclined plate are arranged above a sludge collecting hopper, wherein vergence directions of the lower inclined plate and the upper inclined plate are opposite and form a certain included angle. The high-efficiency depositiondevice for mines utilizes a mechanical stirring reaction to replace a bafflement reaction, and adopts the double-layer inclined plate (pipe) filling material in the deposition zone, wherein the lowerinclined plate and the upper inclined plate are arranged crosswise, and thus bulk-flow, high-efficiency and high-quality treatment effects on sewage are obtained and an overall treatment capability is improved 2 to 5 times. The high-efficiency deposition device for mines integrates the oil removal zone and deposition tank equipment, adopts a standing oil removal method or a dissolved air oil removal method, and realizes effective treatment on mining industry sewage having different oil content ratios.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a mine-used high-efficiency sedimentation device. Background technique [0002] The existing inclined plate (tube) sedimentation tank is used in low-turbidity sewage and water purification systems such as urban sewage and river water purification, such as figure 1 As shown, the inclined plate (tube) sedimentation tank is usually composed of two parts, the front part is the reaction zone 1, and the back end is the sedimentation zone 2. The reaction area usually adopts the form of folded plate reaction, which uses water to flow back and forth between each folded plate to achieve the mixed reaction of chemicals and sewage and increase the contact time between chemicals and sewage. The reaction time in this area is 20 to 25 minutes. Sedimentation zone 2 is composed of upper and lower parts, the upper part is inclined plate (pipe) packing area 2-2, and the lower part is mud ...
