Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a papermaking wastewater recovery and treatment device. Background Art

[0002] Paper mills generate a large amount of wastewater during the production process. The wastewater contains many pollutants. According to national environmental protection requirements, the wastewater needs to be purified before it can be discharged.

[0003] According to the existing technology, reagents need to be added to neutralize the wastewater during wastewater treatment. However, the reagents are injected through a special feed pipe during the addition process. This injection method will increase the distance the reagents need to enter the wastewater. During the purification process, the reagents cannot be completely neutralized by the wastewater, and some of them will remain in the box. This will lead to excessive addition of reagents in the subsequent addition process. Excessive addition of reagents will not only increase the cost of purifying wastewater, but also the excess unneutralized reagents will be discharged along with the wastewater, causing pollution to the surrounding environment during the discharge process. At the same time, the single stirring method during the addition of reagents is not conducive to the fusion of reagents and wastewater. Utility Model Content

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0022] A papermaking wastewater recovery and treatment device provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, a papermaking wastewater recovery and treatment device provided by the utility model comprises a box body 1, a motor 2 is fixedly connected to the top of the box body 1, a driving gear 3 is fixedly connected to one end of the motor 2, a gear plate 4 is meshedly connected to one side of the driving gear 3, a rotating rod 5 is fixedly connected to the bottom center of the gear plate 4, one end of the rotating rod 5 is fixedly connected to a connecting frame 6, a connecting plate 7 is fixedly connected to the bottom of the connecting frame 6, a water spray pipe 8 is fixedly connected to one side of the connecting plate 7, the water spray pipe 8 is arranged in a concave shape, a water spray hole 9 is provided at one side of the water spray pipe 8, both sides of the water spray pipe 8 are rotatably connected to the rotating rod 10 in a through-shaped manner, one end of the rotating rod 10 is fixedly connected to a baffle 21 in an annular shape, both ends of the rotating rod 10 are fixedly connected to rotating blocks 11, and the outer wall of the rotating block 11 is fixedly connected to a stirring fan blade 12 in an annular shape;

[0024] The bottom of the connecting frame 6 is fixedly connected with a stabilizing frame 14, and the side wall of the stabilizing frame 14 is slidably connected to the inner wall of the box body 1. The top of the connecting frame 6 is fixedly connected with a connecting pipe 15 in a connected state, and one end of the connecting pipe 15 is fixedly connected to the side wall of the gear plate 4 in a connected state, and one end of the connecting pipe 15 is fixedly connected to a storage box 16 in a connected state. There are two storage boxes 16. The connecting pipe 15 is arranged in a ring shape at the top of the stabilizing frame 14. The number of connecting pipes 15 is four. The connecting plate 7 is arranged in a ring shape at the bottom of the connecting frame 6. The number of connecting frames 6 corresponds to the number of water spray pipes 8. The side wall of the box body 1 is fixedly connected with a water inlet pipe 18 in a connected state, and the side wall of the box body 1 is located at the bottom of the water inlet pipe 18 in a connected state. The position of the drainage pipe 19 is fixedly connected, one end of the rotating rod 5 is fixedly connected to the support ring 13, and one end of the connecting plate 7 is fixedly connected to the top of the support ring 13.

[0025] In the first embodiment, the driving gear 3 is driven by the motor 2 to engage the gear plate 4 to rotate the gear plate 4, which can drive the connecting frame 6 on the rotating rod 5 to rotate during the rotation. The connecting frame 6 can drive the water spray pipe 8 on the connecting plate 7 to move during the rotation. When the water spray pipe 8 extracts the reagent in the storage box 16 through the connecting pipe 15, it will be sprayed through the water spray hole 9. The thrust of the sprayed reagent acts on the baffle 21. In this way, not only can the reagent be directly added into the wastewater, but it can also be stirred and mixed when added, thereby improving the mixing efficiency of the reagent and the wastewater, and at the same time reducing the use of the reagent. The reduction in the use of the reagent can reduce the pollution to the surrounding environment, and can also save purification costs and maintain corporate benefits.

[0026] One end of the rotating rod 5 is fixedly connected to the conveying shaft 17 , the gear plate 4 is rotatably connected to the top of the box body 1 in a penetrating manner, and the bottom of the box body 1 is fixedly connected to the base 20 .

[0027] In the second embodiment, when the rotating rod 5 rotates, the conveying shaft 17 can be driven to rotate. Since the conveying shaft 17 is bowl-shaped, the wastewater at the bottom of the box 1 can be driven to move upward, and when it reaches the highest point, it can flow down, thereby forming a scooping action, which can not only improve the neutralization efficiency of the reagent and the wastewater, but also avoid the solution of impurities in the wastewater at the bottom, affecting the mixing quality.

[0028] The working principle and use process of the utility model are as follows: waste water is sent into the water inlet pipe 18, and then the motor 2 is started to drive the driving gear 3 to rotate. When the driving gear 3 rotates, it can drive the gear plate 4 to rotate. When the gear plate 4 rotates, it can drive the connecting frame 6 to rotate through the rotating rod 5. When the connecting frame 6 rotates, it can drive the water spray pipe 8 to move through the connecting plate 7. At the same time, the water spray pipe 8 can draw the reagent in the storage box 16 through the connecting pipe 15, and then increase the pressure and spray it out. When it is sprayed through the water spray hole 9, the spraying force will act on the baffle 21, thereby rotating the rotating rod 10. When the rotating rod 10 rotates, it can drive the stirring blade 12 to rotate through the rotating block 11. At the same time, the rotating rod 5 will also drive the conveying shaft 17 to rotate.
