Description

Technical Field

[0001] The utility model relates to the field of sedimentation and filtration, in particular to a mineral powder and waste slag sedimentation and filtration device. Background Art

[0002] Mineral powder is widely used in metallurgy, agriculture, medicine and other fields. However, a large amount of waste slag will be generated in the production process, and a small amount of mineral powder will still remain in the waste slag. During the production process, the waste slag needs to be cleaned and the mineral powder remaining in the waste slag needs to be extracted to maximize the utilization of mineral resources.

[0003] In the prior art, the mixed liquid after the waste residue is cleaned is simply filtered and precipitated, so that a small amount of waste residue still exists in the precipitate of the mineral powder, so that the purity of the mineral powder does not meet the use requirements. The mineral powder still needs to be purified for the second time, which invisibly increases the workload. Utility Model Content

[0004] (1) Technical issues to be solved

[0012] Preferably, a box door is rotatably connected to the side surface of the bottom of the box body, and a third handle is fixedly connected to the side surface of the box door.

[0013] (3) Beneficial effects

[0014] 1. The inclined arrangement of the two filter elements increases the filtering area of the mixed liquid.

[0023] Embodiment 1

[0024] A sedimentation and filtration device for mineral powder waste residue, as Figures 1-5 shown, which includes a box body 1. A water inlet pipe 2 is connected to the top of the box body 1. Between the opposite inner sides of the box body 1, a fixed bottom plate 11 is fixedly connected. At both ends of the upper surface of the fixed bottom plate 11, upper fixed side plates 4 are fixedly connected. The side surfaces of the fixed side plates 4 are fixedly connected to the inner side surfaces of the box body 1. The cross-section of the upper fixed side plate 4 is trapezoidal. Between the opposite side surfaces of the two upper fixed side plates 4, two hydrophobic plates 12 are fixedly connected. The hydrophobic plates 12 are inclined. The hydrophobic plates 12 are provided with semicircular cross-section hydrophobic grooves 1201. At both ends of the fixed bottom plate 11 and below the hydrophobic grooves 1201, rectangular through holes are opened. The width of the rectangular through holes is the same as the width of the hydrophobic plates 12. After the mixed liquid after cleaning the waste residue enters the box body 1 from the water inlet pipe 2, the hydrophobic plates 12 expand the water outlet surface of the mixed liquid, and the mixed liquid flows downward through the rectangular through holes opened on the fixed bottom plate 11;

[0025] At both ends of the lower surface of the fixed bottom plate 11, lower fixed side plates 6 are fixedly connected. The cross-section of the fixed side plates 6 is inverted trapezoidal. The side surfaces of the lower fixed side plates 6 are fixedly connected to the inner side surfaces of the box body 1. Between the two lower fixed side plates 6, two filter elements 15 are slidably connected. Since the fixed side plates 6 are inverted trapezoidal, the two filter elements 15 are inclined. The lower surface of the lower fixed side plate 6 is fixedly connected with a limit frame 16. Inside the limit frame 16, a first-stage sedimentation tank 7 is slidably connected in a limited manner. On another side surface of the box body 1, a chute matching the first-stage sedimentation tank 7 is opened. A first handle 8 is fixedly connected to the side surface of the first-stage sedimentation tank 7. After the mixed liquid flows downward and contacts the filter elements 15, the inclined filter elements 15 filter the mixed liquid. While the mixed liquid flows downward along the filter elements 15, the waste residue on the surface of the filter elements 15 can be washed away, and the waste residue is washed into the first-stage sedimentation tank 7. According to the actual use time and times, the first-stage sedimentation tank 7 is pulled out to remove the waste residue inside.

[0026] Inside the box body 1 and below the first-stage sedimentation tank 7, a second-stage sedimentation tank 14 is arranged. The second-stage sedimentation tank 14 can be installed with universal wheels at the bottom according to actual use needs to facilitate the use of the second-stage sedimentation tank 14. A water outlet pipe 3 is detachably connected to the side wall of the second-stage sedimentation tank 14. The water outlet pipe 3 penetrates the side wall of the box body 1 and extends to the outside of the box body 1. The water outlet pipe 3 is located at the upper part of the side wall of the second-stage sedimentation tank 14, which is convenient for the clear water to flow out after the mixed liquid inside the second-stage sedimentation tank 14 precipitates. A filter plate 13 is slidably connected to the upper end of the second-stage sedimentation tank 14. The mixed liquid after being filtered by the filter elements 15 flows downward, and the filter plate 13 performs secondary filtration on the mixed liquid to filter the waste residue in the mixed liquid again. The mixed liquid after secondary filtration flows into the second-stage sedimentation tank 14 and precipitates in the second-stage sedimentation tank 14. The precipitated clear water flows out from the water outlet pipe 3.

[0027] A chute matching the filter element 15 is provided on the side of the box body 1. A second handle 9 is fixedly connected to the side of the filter element 15, and the filter element 15 can be replaced according to the usage time and frequency.

[0028] A box door 5 is rotatably connected to the side of the bottom of the box body 1. A third handle 10 is fixedly connected to the side of the box door 5. The setting of the box door 5 facilitates the removal and replacement of the secondary sedimentation tank 14.

[0029] The above embodiments only represent the preferred embodiments of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
