    As shown in Fig. 1 to Fig. 4, the present invention disclosures a fast settlingconcentration tank for sewage in gangue. The fast settling concentration tankcomprises an outer cylinder 1 and an inner cylinder 2 sleeved inside the outer cylinder1 by a first bracket 3. The first bracket 3 is composed of a plurality of connectingrods to provide a support and retaining effect, which doesn't reduce the static cleanwater area to ensure the cleaning effect. The upper end of the inner cylinder 2 is asewage inlet 21. A baffle plate 4 is provided in the middle of the inner cylinder 2 by asecond bracket 5. A feeding gap 41 is formed between the edge of the baffle plate 4and the inner wall of the inner cylinder 2. The second bracket 5 is composed of aplurality of connecting rods to provide a support and retaining effect, which doesn'treduce the passage (the feeding gap 41) between the feeding baffle area and the mud settling area to ensure the cleaning effect. Preferably, the baffle plate 4 has an arc 3 shape which has a high middle portion and a lower edge. Preferably, the diameter ofthe baffle plate 4 is a half of the diameter of the inner cylinder 2, such that the baffleplate 4 provides a better baffle effect. At least one annular return plate 6 is fixed onthe outer wall of the inner cylinder 2. This embodiment has two annular return plates6, one is fixed at the lower end of the inner cylinder 2 and the other is fixed at themiddle section of the inner cylinder 2. An overflow gap 61 is formed between theouter edge of each annular return plate 6 and the inner wall of the outer cylinder 1.Preferably, the annular return plate 6 is inclined at an angle of 30 degrees relative to ahorizontal plane, so that the mud can flow back well to prevent slag from exiting through the overflow outlet 12.
    A residue outlet 11 is formed by tapering the diameter of the lower portion of theouter cylinder 1. The diameter of the residue outlet 11 is a quarter of the diameter ofthe inner cylinder 2, such that the settling time can be controlled well to enhance theconcentration efficiency. An overflow tank 13 is formed at the upper end of the outercylinder 1. The overflow outlet 12 of the overflow tank 13 is separated from thesewage inlet 21. ln order to separate the slag well to enhance the water quality fromthe overflow outlet 12, in the embodiment the overflow outlet 12 is located at the outer wall of the overflow tank 13.
    The baffle plate 4 of the present invention divides the inner cylinder 2 into twosections, one section above the baffle plate 4 as a feeding baffle plate area and theother section under the baffle plate 4 to the residue outlet of the outer cylinder 1 as amud settling area. Between the inner cylinder 2 and the outer cylinder 1 is a staticclean water area. As shown in Fig. 4, when the present invention is applied to a sewage treatment, two concentration tanks are connected.
    When in use, the sewage in gangue is drained into a gangue pool 10 and addedwith Aluminum Oxide and then stirred to form mud. After that, the mud is sent to thefast settling concentration tank of the present invention by a mud pump 20. The mudflows to the feeding baffle area of the inner cylinder 2 through the sewage inlet 21.The baffle plate 4 is to decelerate and disperse the mud. The mud enters the mudsettling area through the feeding gap 41. The sludge is stopped in the mud settling area by the return plate 6 by way of settling of specific gravity. The slag drops to the bottom of the outer cylinder 1 and drains from the residue outlet 11. Theconcentration of the slag drained from the first concentration tank can be 40% to 60%,and the water enters the static clean water area through the overflow gap 61. The 4 water level of the static clean water area ascends to the overflow outlet 12 at theupper end of the outer cylinder 1, and then the clean water overflows. The cleanwater drained from the first concentration tank naturally flows to the secondconcentration tank for a second settling concentration by the same principle of the firsttank. The clean water flows to the bottom of a clean water tank 30 through the pipepressure. The water quality of the purified water from the top or the middle of thetank is stable and better. Through a clean water pipe, the water can be reused.The clean water tank 30 can be used as a high level pool. The slag is dehydratedthrough a press or a belt-type hydroextrator, so that the gangue can be reuse to achieve no waste mine clean production.
    Although particular embodiments of the present invention have been described indetail for purposes of illustration, various modifications and enhancements may bemade without departing from the spirit and scope of the present invention.Accordingly, the present invention is not to be limited except as by the appended claims.
