[0001] This utility model relates to the field of recycling technology, and in particular to a device for recycling tailings water from a desulfurization flotation machine. Background Technology

[0002] The desulfurization flotation machine tailings water recycling device is an environmental protection equipment used to treat waste slurry water after flotation. It filters water through a multi-stage filtration system (such as quartz sand and activated carbon filtration) to realize water resource utilization, reduce fresh water consumption and sewage discharge. It is widely used in desulfurization processes in coal-fired power plants, steel plants and other industries, significantly improving environmental benefits and production economy.

[0003] Currently, filtration is required during the recycling of tailings water from desulfurization flotation machines. However, existing filtration systems often require shutdown for maintenance and cleaning, leading to interruptions in filtration operations and impacting processing efficiency. Utility Model Content

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

[0021] Reference Figure 1-3 A desulfurization flotation machine tailings water recycling device includes a cylindrical box 1. The right side wall of the box 1 has an opening. A cover plate 11 corresponding to the opening is rotatably connected to the right side wall of the box 1 for sealing the opening. A second locking screw 12 is provided on the side of the cover plate 11 away from the box 1 for fixing the cover plate 11. The cover plate 11 is fixed to the box 1 by the second locking screw 12. A rubber block 14 is fixedly connected to the side of the cover plate 11 facing the box 1 for sealing the opening. The end of the rubber block 14 away from the cover plate 11 slides into the opening. A second rubber gasket 13 is fixedly connected to the side of the cover plate 11 facing the box 1 for improving the sealing performance of the cover plate 11.

[0022] In this embodiment, a vertically arranged switching column 2 is rotatably connected to the inner wall of the housing 1 for switching the positions of the two hollow slots. A first rubber pad 3 is fixedly connected to both the upper and lower sides of the switching column 2 to improve the sealing between the upper and lower ends of the switching column 2 and the inner wall of the housing 1. The side of the first rubber pad 3 away from the switching column 2 abuts against the inner wall of the housing 1. A cut corresponding to the hollow slot is provided on the outer side wall of the first rubber pad 3. A rotating rod 8 is fixedly inserted into the upper end of the switching column 2 to drive the switching column 2 to rotate. The upper end of the rotating rod 8 is rotatably connected to the inner top of the housing 1. The lower end of the rotating rod 8 passes through the switching column 2 and the housing 1 and is fixedly connected to a knob 9 to drive the rotating rod 8 to rotate. The rotating rod 8 and the housing 1 are rotatably connected. A vertically arranged first locking screw 10 is inserted into the lower end of the knob 9 near the edge to cooperate with the slot to prevent the knob 9 from loosening. Multiple slots corresponding to the first locking screw 10 are distributed in a ring at the lower end of the housing 1.

[0023] In this embodiment, the switching column 2 is provided with two vertically arranged hollow slots, which are located on the left and right sides of the rotating rod 8 respectively. The upper and lower sides of the box 1, near the left edge, are provided with openings that communicate with the hollow slots. Three horizontally arranged filter plates 4 are slidably inserted into the inner sidewall of the hollow slots from top to bottom for installing filter screens 5. The filter screens 5 in the three filter plates 4 are stainless steel wedge wire filter screens, polyester fiber pleated filter screens, and ceramic sintered filter screens, respectively, for multi-stage filtration. The filter plates 4 are provided with filter ports, and horizontally arranged filter screens 5 are fixedly embedded in the filter ports for filtering sewage.

[0024] In this embodiment, the inner wall of the hollow groove and the side near the rotating rod 8 are provided with a slot corresponding to the filter plate 4. One end of the filter plate 4 slides into the slot. A first magnet 7 is fixedly connected to the end of the filter plate 4 that extends into the slot, which is used to cooperate with the second magnet to magnetically position the filter plate 4. A second magnet that attracts the first magnet 7 is fixedly connected to the inner wall of the slot. An insertion port is provided on the inner wall of the hollow groove and the side away from the rotating rod 8. The other end of the filter plate 4 slides into the insertion port. A third rubber pad is fixedly connected to the inner wall of the insertion port to improve the sealing between the filter plate 4 and the insertion port. A groove is provided on the end of the filter plate 4 that extends into the insertion port. A semi-circular handle 6 is fixedly connected to the inner wall of the groove to facilitate the user to pull out the filter plate 4.

[0025] In this embodiment, the external water inlet pipe is first fixedly connected to the opening at the top of the tank 1, and then the external water outlet pipe is fixedly connected to the opening at the bottom of the tank 1. After the sewage enters the left hollow trough through the opening, it undergoes three-stage filtration through the filter screens 5 inside the three filter plates 4, and finally flows into the outlet pipe through the opening at the bottom of the tank 1, completing the filtration operation. During maintenance and cleaning, the two sets of hollow troughs and the internal filter plates 4 and filter screens 5 form an alternating filtration mechanism: the knob 9 is manually rotated to drive the rotating rod 8 and the switching column 2 to rotate, aligning the right hollow trough with the opening (achieving the interchange of the left and right hollow trough positions). The right hollow trough after switching immediately starts the filtration operation, ensuring uninterrupted flow. During maintenance, the second locking screw 12 is unscrewed and the cover plate 11 is unscrewed. The filter plate 4 can be quickly pulled out by holding the handle 6 through the opening, significantly improving the convenience of cleaning the filter screen 5.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
