Technical Field

[0001] The utility model belongs to the technical field of dissolved air flotation machines, and particularly relates to a dissolved air flotation machine convenient for pipeline docking. Background Technique

[0002] The dissolved air flotation machine is a device widely used in the field of sewage treatment. It mainly dissolves air into the sewage to form bubbles, so that pollutants adhere to the bubbles and float to the water surface, thereby realizing solid-liquid separation. The dissolved air flotation machine plays an important role in the treatment of various industrial wastewaters, domestic sewage and aquaculture wastewaters. However, in the actual use process, it is difficult to dock the dissolved air flotation machine with the pipeline system. When the inlet and outlet pipelines of the traditional dissolved air flotation machine are docked with the external pipelines, due to the weight of the pipelines themselves and the difficulty in precisely adjusting their positions, a large amount of manpower and time are often required for adjustment, which affects the installation efficiency and operation stability of the equipment. During the docking process, the support and fixation methods of the pipelines are not scientific enough, which easily leads to the deviation of the docking position and affects the normal operation of the equipment. We design a dissolved air flotation machine convenient for pipeline docking to provide another technical solution for the above technical problems. Content of the Utility Model

The output end of the driving motor 8 is fixed with a first horizontal threaded rod 9. The end of the first horizontal threaded rod 9 far from the driving motor 8 is fixed with a second horizontal threaded rod 10. The thread directions of the first horizontal threaded rod 9 and the second horizontal threaded rod 10 are opposite. Horizontal moving boxes 11 are screwed on the outer sides of both the first horizontal threaded rod 9 and the second horizontal threaded rod 10. The horizontal moving boxes 11 are located inside the horizontal U-shaped frame 7 and are slidably connected to the horizontal U-shaped frame 7;

[0023] A dovetail slider is fixed to the bottom of the horizontally moving box 11. A dovetail chute adapted to the dovetail slider is provided inside the horizontal U-shaped frame 7. The horizontally moving box 11 is slidably connected to the horizontal U-shaped frame 7 through the cooperation of the dovetail slider and the dovetail chute. Through the arrangement of the dovetail slider and the dovetail chute, the horizontally moving box 11 can slide on the top of the horizontal U-shaped frame 7. Furthermore, the arrangement of the dovetail slider and the dovetail chute can guide the moving track of the horizontally moving box 11 inside the horizontal U-shaped frame 7, making the sliding of the horizontally moving box 11 smoother;

[0024] A vertically sliding column 13 is slidably connected inside the top end of the horizontally moving box 11. The top of the vertically sliding column 13 is fixedly connected to the arc-shaped support base 12;

[0025] Here, the operation of the drive motor 8 enables the first horizontal threaded rod 9 and the second horizontal threaded rod 10 to rotate. The rotation of the first horizontal threaded rod 9 and the second horizontal threaded rod 10 enables the two horizontally moving boxes 11 to slide on the top of the horizontal U-shaped frame 7, and the moving directions of the two horizontally moving boxes 11 are opposite, so that the distance between the two arc-shaped support bases 12 can be adjusted. Furthermore, the arc-shaped support base 12 can support the horizontal connecting pipe 2 and adjust the support distance of the arc-shaped support base 12;

[0026] On one side of the air flotation machine housing 1 and at the top of the horizontal connecting pipe 2, a horizontal fixing plate 5 is fixed. A plurality of hydraulic cylinders 6 are fixed to the bottom of the horizontal fixing plate 5. The output end of the hydraulic cylinder 6 is fixed to an L-shaped connecting plate 3.

[0027] A horizontal slider is fixed to the bottom of the horizontal U-shaped frame 7. A horizontal chute adapted to the horizontal slider is provided inside the horizontal support plate 4. The horizontal U-shaped frame 7 is slidably connected to the horizontal support plate 4 through the arrangement of the dovetail slider and the dovetail chute, enabling the horizontal U-shaped frame 7 to slide horizontally on the top of the horizontal support plate 4. Furthermore, the two arc-shaped support bases 12 can move, so that the arc-shaped support base 12 can support the horizontal connecting pipe 2, and furthermore, the support position of the arc-shaped support base 12 can be adjusted;

[0028] Here, the operation of the hydraulic cylinder 6 enables the L-shaped connecting plate 3 to lift. The lifting of the L-shaped connecting plate 3 enables the arc-shaped support base 12 to lift through the horizontal support plate 4 and the horizontal U-shaped frame 7. Furthermore, the support force of the arc-shaped support base 12 on the horizontal connecting pipe 2 can be adjusted to prevent the horizontal connecting pipe 2 from bending during long-term use;

[0029] The shock-absorbing mechanism includes a rectangular sliding plate 14. At the bottom of the vertical sliding column 13 and inside the lateral moving box 11, there is a rectangular sliding plate 14. The rectangular sliding plate 14 is located inside the lateral moving box 11 and is slidably connected to the lateral moving box 11. Inside the lateral moving box 11, there is an oil cylinder 15. A piston rod is slidably connected inside the oil cylinder 15. The top of the piston rod is fixedly connected to the rectangular sliding plate 14. A rigid spring 16 is arranged between the rectangular sliding plate 14 and the lateral moving box 11 and outside the oil cylinder 15.

[0030] A vertical sliding groove is formed inside the lateral moving box 11. The rectangular sliding plate 14 is located inside the vertical sliding groove and is slidably connected to the lateral moving box 11 through the vertical sliding groove. Through the arrangement of the vertical sliding groove, the rectangular sliding plate 14 can slide inside the lateral moving box 11. The sliding of the rectangular sliding plate 14 enables the piston rod to slide inside the oil cylinder 15, and also enables the rigid spring 16 to undergo a phase change under force.

[0032] Working principle: The operation of the driving motor 8 enables the first lateral threaded rod 9 and the second lateral threaded rod 10 to rotate. The rotation of the first lateral threaded rod 9 and the second lateral threaded rod 10 enables the two lateral moving boxes 11 to slide on the top of the lateral U-shaped frame 7, and the moving directions of the two lateral moving boxes 11 are opposite, so that the distance between the two arc-shaped support seats 12 can be adjusted. Furthermore, the arc-shaped support seats 12 can support the lateral connecting pipe 2 and adjust the support distance of the arc-shaped support seats 12.

[0033] The operation of the hydraulic cylinder 6 enables the L-shaped connecting plate 3 to lift. The lifting of the L-shaped connecting plate 3 enables the arc-shaped support seats 12 to lift through the lateral support plate 4 and the lateral U-shaped frame 7. Furthermore, the support force of the arc-shaped support seats 12 on the lateral connecting pipe 2 can be adjusted to prevent the lateral connecting pipe 2 from bending during long-term use. Through the adjustable distance and height of the arc-shaped support seats 12, the arc-shaped support seats 12 can better support the lateral connecting pipe 2, so that the lateral connecting pipe 2 can be supported during docking, and the convenience of docking between the lateral connecting pipe 2 and the air flotation machine housing 1 can be improved.

[0034] When the horizontal connecting pipe 2 vibrates, the vertical sliding column 13 can vertically slide inside the horizontal moving box 11, the rectangular sliding plate 14 can slide inside the horizontal moving box 11, the piston rod can slide inside the oil cylinder 15, the rigid spring 16 can undergo a force-induced phase change, so that the horizontal connecting pipe 2 can be vibration-damped and the service life of the horizontal connecting pipe 2 can be extended.
