DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] Reference Figures 1-3The utility model relates to a water purification device for mine wastewater treatment, including box 1, the top side of box 1 is equipped with the sedimentation chamber 3 through the L type partition 2, the inside space of box 1 below the sedimentation chamber 3 is reaction chamber 4, the first communication port 5 is passed through and is established in the middle part of partition 2, the upper portion of the side of partition 2 opposite to the sedimentation chamber 3 is equipped with the switch assembly for opening and closing the first communication port 5, the lower portion of the side of partition 2 opposite to the sedimentation chamber 3 is equipped with filter plate 6.

[0022] Refer to Figures 2-4 The bottom of sedimentation chamber 3 is fixedly connected with the inclined grating plate 7, and the inclined upper end of grating plate 7 is located directly below the first communication port 5, and the inclined lower end of grating plate 7 is provided with the first cleaning port 8 on the side wall of box 1 corresponding to the inclined lower end. The first cleaning port 8 should be provided with a first sealing plate 17. When it is necessary to clean the particulate impurities in the sedimentation chamber 3, the first sealing plate 17 of the first cleaning port 8 can be opened, and the first sealing plate 17 can be connected at the first cleaning port 8 by means of hinged cooperation and lock buckle. The first sealing plate 17 is prior art, and will not be described in detail. The side of the top surface of box 1 away from filter plate 6 is provided with a water inlet pipe 15, and the side of the lower part of box 1 away from the first sealing plate 17 is provided with a water outlet pipe 16.

[0023] The water purification device for mine wastewater treatment is used. The wastewater first enters the sedimentation chamber 3 in the box 1. The larger particulate impurities in the wastewater stay above the inclined lower end of the grating plate 7, and the smaller particulate impurities are deposited below the grating plate 7. After the sedimentation is completed, the first cleaning port 8 is opened by the switch assembly. The supernatant is filtered by the filter plate 6 and enters the reaction chamber 4. The precipitant is added to the reaction chamber 4. After the precipitation, the upper clear water is discharged from the box 1. During the precipitation process in the reaction chamber 4, the sedimentation chamber 3 can simultaneously carry out a new round of wastewater sedimentation, thereby improving the water purification efficiency.

[0024] In actual use, the first communication port 5 can use a large opening or a plurality of small openings. The large opening scheme is easy to produce a larger water flow in the middle of the first communication port 5, which may cause the sediment particles to be stirred and mixed into the supernatant. Therefore, the number of first communication ports 5 on the partition 2 is not less than two in the subsequent scheme of a plurality of small openings.

[0025] Refer to Figures 2-4The switch assembly comprises a switch plate 9 which is arranged on the side of the partition plate 2 opposite to the sedimentation cavity 3 and slides up and down, a plurality of second communication ports 10 are formed on the switch plate 9 and correspond to the first communication ports 5 one by one, and an electric push rod 11 is fixedly installed on the top of the box body 1 and drives the switch plate 9 to slide up and down. The switch assembly drives the switch plate 9 to slide up and down through the electric push rod 11, so that the change of the coincident part of the first communication ports 5 and the second communication ports 10 is realized, when the first communication ports 5 and the second communication ports 10 are completely staggered, the first communication ports 5 are blocked by the switch plate 9, and the closing of the first communication ports 5 is realized; when the first communication ports 5 and the second communication ports 10 are coincident, the wastewater continuously passes through the first communication ports 5 and the second communication ports 10, and the opening of the first communication ports 5 is realized.

[0026] Since the particulate impurities are located at the lower part of the sedimentation cavity 3, when the switch plate 9 seals the first communication ports 5, the second communication ports 10 are located above the first communication ports 5, so that the first communication ports 5 are opened from top to bottom, and the disturbance to the particulate impurities is reduced.

[0027] The grid plate 7 comprises a plurality of flat steels 12 which are directed to the first cleaning port 8 and a plurality of cross bars 13 which are perpendicular to the flat steels 12, and the top end of the flat steel 12 is higher than the cross bar 13, so that the flat steels 12 are fixed through the cross bars 13, the large particulate impurities are guided through a plurality of mutually parallel flat steels 12, and the large particulate impurities move obliquely downwards on the gap between adjacent flat steels 12.

[0028] The bottom surface of the reaction cavity 4 is inclined, and the inclined lower end of the reaction cavity 4 is located directly below the first cleaning port 8, the second cleaning port 14 is arranged on the side wall of the box body 1 and located at the inclined lower end of the reaction cavity 4, and the second sealing plate 18 should be arranged at the second cleaning port 14, and the second sealing plate 18 is similar to the first sealing plate 17, and details are not repeated. The inclined bottom surface of the reaction cavity 4 can make the sediment after the reaction concentrate at the second cleaning port 14, which is convenient for subsequent cleaning, avoids affecting the discharge of the clear liquid, and improves the treatment effect and efficiency.
