Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a lifting device for regulating dissolved oxygen in a high-efficiency sedimentation tank. Background Art

[0002] High-efficiency sedimentation tanks are commonly used facilities for sewage treatment. Sedimentation tanks are structures that use sedimentation to remove suspended matter from water. Sedimentation tanks are usually equipped with water inlet channels. Existing water inlet channels often have gratings on the top for workers to walk on.

[0003] At present, it is often necessary to adjust the dissolved oxygen in the sedimentation tank during sewage treatment. Generally, a cover is added to the top of the grille of the inlet channel. Opening the cover increases the dissolved oxygen, and closing the cover reduces the dissolved oxygen. However, it is troublesome to manually move the cover, especially since the cover is large in size. It is laborious to manually move and lift it as a whole. In addition, when there is no suitable placement location, the cover needs to be moved away, which increases the workload and makes the cover less practical.

[0004] Therefore, there is a need for a lifting device that is easy to operate, saves time and effort, and is used to efficiently regulate dissolved oxygen in a sedimentation tank. Utility Model Content

[0010] As an optimal technical solution for a lifting device for regulating dissolved oxygen in an efficient sedimentation tank of the utility model, the first connecting belt includes a ring, an elastic belt and a hook. The ring is sleeved on the outer side of the connecting arc plate, and the outer side of the ring is fixedly connected with an elastic belt. One end of the elastic belt is fixedly provided with a hook, and the hook is engaged on the first railing.

[0011] As a preferred technical solution of the utility model for a lifting device for regulating dissolved oxygen in an efficient sedimentation tank, a second support shaft is fixedly provided at the other end of the inner wall of the support frame, and one end of the second baffle is movably sleeved on the second support shaft.

Two baffles are movably sleeved on the inner side of the support frame through two support shafts, and elastic bands with hooks are respectively connected to the tops of the two baffles. When the dissolved oxygen in the sedimentation tank is reduced, the baffles on both sides are located on the inner side of the support frame to cover the grille. When the dissolved oxygen in the sedimentation tank needs to be increased, one end of the baffle can be lifted by pulling the elastic band, so that the baffle is erected and no longer covers the grille, and then the hooks can be hung on the railings on both sides of the water inlet channel.
