Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-6 As shown, this utility model provides a treatment device for fluorochemical wastewater, including a first tank 1 and a second tank 2. The top of the first tank 1 is connected to an inlet pipe 101, and the side wall of the second tank 2 is connected to an outlet pipe 201.
[0024] In this embodiment, coagulant and flocculant are added into the first tank 1 through the feed pipe 101. Through adsorption, bridging and other effects, fluoride particles and other suspended solids in the wastewater are agglomerated into larger flocs, thereby treating the wastewater.
[0025] A partition 3 is fixedly connected to the inner wall of the first box 1. A rectangular hole 8 is opened on the end face of the partition 3. A first blocking plate 9 is hinged to the inner wall of the rectangular hole 8. A filter screen 4 is provided inside the first box 1. A rack 13 is fixedly connected to the side wall of the filter screen 4. A long rod 10 is rotatably connected to the inner wall of the first box 1. A gear 11 and two connecting ropes 12 are fixedly connected to the arc surface of the long rod 10. The ends of the two connecting ropes 12 away from the long rod 10 are fixedly connected to the first blocking plate 9.
[0026] In this embodiment, the long rod 10 is rotated by the meshing of the rack 13 and the gear 11 to wind the connecting rope 12, thereby opening the first blocking plate 9 and facilitating the falling of flocculent material. When the first blocking plate 9 is engaged inside the rectangular hole 8, there will be no leakage between the first blocking plate 9 and the rectangular hole 8.
[0027] In an optional embodiment: a collection frame 14 is provided inside the first housing 1, the collection frame 14 is located below the partition 3, the filter screen 4 is located above the partition 3, and the end face of the partition 3 is in contact with the filter screen 4.
[0028] In an optional embodiment: a drain hole 16 is provided at the connection between the first box 1 and the second box 2, and a second blocking plate 1601 is provided inside the drain hole 16. A pull rod 15 is fixedly connected to the surface of the second blocking plate 1601, and the end of the pull rod 15 away from the second blocking plate 1601 slides through the second box 2.
[0029] It should be noted that the operation is more convenient by controlling the opening and closing of the drain hole 16 by pulling the lever 15.
[0030] In an optional embodiment: a spring 17 is fitted onto the arc surface of the pull rod 15, and the two ends of the spring 17 are fixedly connected to the pull rod 15 and the second housing 2, respectively.
[0031] It should be noted that the spring 17 serves to make the second blocking plate 1601 more secure in the drain hole 16.
[0032] In an optional embodiment: a connecting plate 5 is fixedly connected to the surface of the filter screen 4, a fixing sleeve 6 is fixedly connected to the end face of the connecting plate 5, an L-shaped rod 7 is fixedly connected to the front of the first housing 1, and the fixing sleeve 6 is slidably sleeved on the arc surface of the L-shaped rod 7.
[0033] It should be noted that when the filter screen 4 moves, the fixing sleeve 6 will slide along the arc surface of the L-shaped rod 7, which will limit the movement of the filter screen 4 and prevent the filter screen 4 from shifting.
[0034] In an optional embodiment: a limiting hole is provided on the front of the first housing 1, and the connecting plate 5 passes through the first housing 1 by means of the limiting hole.
[0035] It should be noted that the limiting hole ensures that the connecting plate 5 is not affected when it moves.
[0036] The working principle of this utility model is as follows: During use, wastewater is fed into the first tank 1 through the inlet pipe 101. Then, coagulant and flocculant are added into the first tank 1 through the inlet pipe 101. Through adsorption and bridging, fluoride particles and other suspended solids in the wastewater agglomerate into larger flocs. After the reaction is complete, the pull rod 15 is pulled, and the spring 17 is in a stretched state, pulling the second blocking plate 1601 out of the drain hole 16. At this time, the treated wastewater inside the first tank 1 flows into the second tank 2. Under the interception of the filter screen 4, the wastewater and flocculants are separated. After the wastewater inside the first tank 1 is discharged, the pull rod is released. 15. Spring 17 rebounds, and the second blocking plate 1601 re-blocks the drain hole 16. At this time, the filter screen 4 is moved by the moving connecting plate 5, causing the flocculent to move closer to the first blocking plate 9. When the rack 13 meshes with the gear 11, the gear 11 drives the long rod 10 to rotate, and the connecting rope 12 will wrap around the arc surface of the long rod 10. The first blocking plate 9 will then rotate, exposing the rectangular hole 8. As the filter screen 4 pushes the flocculent, the flocculent will eventually fall from the rectangular hole 8 into the collection frame 14. The staff can then pull the collection frame 14 out of the first box 1 to process the flocculent inside the collection frame 14.
