Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtrate conditioning tank technology, and in particular to a fly ash washing filtrate conditioning tank. Background Technology
[0002] Fly ash from the combustion of garbage and other waste usually needs to be washed with water to remove dust and heavy metals. The dust and heavy metals in the washed fly ash, along with the wastewater, need to be treated to recover the useful substances.
[0003] Wastewater from fly ash washing is usually collected in a filtrate equalization tank. A certain amount of flocculant is then added and stirred to ensure that the flocculant is evenly mixed with the filtrate in the equalization tank. After a long period of sedimentation, recyclable gypsum powder and heavy metals settle to the bottom, thus completing the reuse of the wastewater.
[0004] However, traditional wastewater treatment involves adding a large amount of flocculant at once to allow the filtrate to react fully. This method makes it difficult to accurately control the amount of flocculant, and the stirring of the filtrate in the filtrate tank greatly increases the settling time of gypsum powder and heavy metal precipitates, reducing work efficiency. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] As a further description of the above technical solution:
[0016] The arc-shaped groove can move directly above the hole and directly below the connecting pipe, and granular flocculant can be poured into the upper end of the hopper, so that residual water inside the arc-shaped groove can be discharged through the hole, and flocculant inside the connecting pipe can fall into the arc-shaped groove.
[0017] As a further description of the above technical solution:
[0018] The internal material of the elastic rod is elastic rubber, and the elastic rod can contact the clamping plate during movement, so that the elastic rod can strike the clamping plate during movement to cause the hopper to vibrate, and the elastic rod can rebound and reset.

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figure 1-9A fly ash washing filtrate conditioning tank includes a storage tank 1, and a mixing structure is fixedly installed on the upper end of the storage tank 1.
[0034] The hybrid structure includes a transfer pipe 2, a first housing 3 fixedly connected to the right end of the transfer pipe 2, a feeding device 4 fixedly connected to the left end of the transfer pipe 2, a water outlet 5 fixedly connected to the front end of the transfer pipe 2, a reinforcing block 6 fixedly connected to the lower end of the transfer pipe 2, a linkage device 7 installed in the middle of the transfer pipe 2, and a water inlet 8 fixedly connected to the rear end of the transfer pipe 2.
[0035] The feeding device 4 includes a second housing 401, a connecting pipe 402 fixedly connected to the upper end of the second housing 401, a hopper 403 fixedly connected to the upper end of the connecting pipe 402, two clamping plates 404 fixedly connected to the right end of the hopper 403, a hole 405 opened at the lower end of the second housing 401, and through holes 406 opened at the upper and lower ends of the middle part of the second housing 401.
[0036] The linkage device 7 includes a first rotating rod 701 and a second rotating rod 702. A cylindrical block 703 is fixedly connected to the middle of the first rotating rod 701. Four arc-shaped grooves 704 are opened at equal angles along the center position at the outer end of the cylindrical block 703. Four elastic rods 705 are fixedly connected at equal angles along the center position at the outer end of the first rotating rod 701. A support block 706 is fixedly connected to the middle of the second rotating rod 702. Multiple rectangular plates 707 are fixedly connected at equal angles along the center position at the outer end of the support block 706. A transmission belt 708 is fixedly connected between the upper ends of the first rotating rod 701 and the second rotating rod 702.
[0037] Please see Figure 4-7 The support block 706 and the rectangular plate 707 are matched with the interior of the first housing 3, and the cylindrical block 703 is matched with the interior of the second housing 401, making it difficult for the support block 706 and the cylindrical block 703 to shift during rotation. The first rotating rod 701 rotates in the middle of the through hole 406, and the second rotating rod 702 rotates in the middle of the left end of the first housing 3. The lower ends of both the first rotating rod 701 and the second rotating rod 702 are rotatably connected to the reinforcing block 6, making it difficult for the first rotating rod 701 and the second rotating rod 702 to shift during rotation.
[0038] Please see Figure 5-8 The arc-shaped groove 704 can move directly above the hole 405 and directly below the connecting pipe 402. Granular flocculant can be poured into the upper end of the hopper 403, allowing residual water inside the arc-shaped groove 704 to drain through the hole 405, and allowing flocculant inside the connecting pipe 402 to fall into the arc-shaped groove 704. The elastic rod 705 is made of elastic rubber, and during movement, it can contact the clamping plate 404, causing the hopper 403 to vibrate by striking the clamping plate 404. The elastic rod 705 can also rebound and return to its original position.
[0039] During filtrate treatment, granular flocculant is first loaded into the hopper 403, and then the filtrate wastewater after fly ash washing is introduced into the transfer pipe 2 through the inlet. When the wastewater flows through the transfer pipe 2, it pushes multiple rectangular plates 707 to move. The multiple rectangular plates 707 drive the second rotating rod 702 to rotate clockwise from a top view through the support block 706. The second rotating rod 702 drives the first rotating rod 701 to rotate counterclockwise from a top view through the transmission belt 708. At the same time as the first rotating rod 701 rotates, it drives the cylindrical block 703 to rotate.
[0040] The arc-shaped trough 704 moves due to the rotation of the cylindrical block 703. When the arc-shaped trough 704 moves directly above the hole 405, a small amount of residual wastewater inside the arc-shaped trough 704 is discharged through the hole 405. Then the arc-shaped trough 704 continues to move to the bottom of the connecting pipe 402. The flocculant inside the hopper 403 falls into the middle of the arc-shaped trough 704, which is now located directly below the connecting pipe 402, through the connecting pipe 402. Then the arc-shaped trough 704 continues to move. When the arc-shaped trough 704 moves to the middle of the transfer pipe 2, the flocculant inside the arc-shaped trough 704 is carried out by the wastewater, so that the wastewater flowing through the transfer pipe 2 mixes with the flocculant and is finally discharged into the storage tank 1.
[0041] During the rotation of the first rotating rod 701, the elastic rod 705 strikes the two clamping plates 404 in sequence and rebounds. When the elastic rod 705 strikes the clamping plates 404, it causes the hopper 403 to vibrate, allowing the granular flocculant inside the hopper 403 to fall into the connecting pipe 402 without getting stuck. This allows for rapid mixing of flocculant and fly ash washing wastewater via the linkage device 7 and the feeding device 4, accurately controlling the amount of flocculant added. Furthermore, the wastewater and flocculant do not require subsequent stirring in the storage tank 1, reducing the settling time of gypsum powder and heavy metal precipitates and improving work efficiency.
[0042] 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.
