Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a sewage treatment interception device. Background Art

[0002] In sewage treatment, sewage will flow into the sedimentation tank along the channel. During the flow of sewage, some debris will float on the surface. As the sewage flows over long distances, more and more debris will float with it. Before treating the sewage, these debris need to be dealt with first. The simplest way is to filter it with a filter.

[0003] Among them, the application number is CN202221243296.6, which is a river floating garbage salvage device. The river floating garbage salvage device has the function of solving the problem of garbage stuck in the salvage claw by cooperating with the cleaning mechanism and the equipment mechanism, so that the limit rod drives the cleaning claw on the limit sleeve to rotate, so that the cleaning claw cleans the garbage stuck inside the salvage claw, which helps to improve the efficiency of the device in salvaging garbage. Among them, the shortcomings are as follows:

[0004] When the staff uses this type of river floating garbage salvage device to salvage and clean the river garbage, the toothed chain belt drives the salvage claw to move synchronously, so that the salvage claw salvages the floating garbage, and the water rising with the garbage is discharged from the drainage holes of the toothed chain belt, thereby facilitating the salvage of the floating garbage. When the floating garbage is salvaged by the salvage claw, since the salvage claw cannot be freely adjusted in length, the salvage claw of a fixed length can only salvage floating garbage on the river surface within a fixed distance range. Some floating garbage will still pass through both sides of this type of river floating garbage salvage device and will not be easy to salvage, resulting in a relatively poor salvage effect of this type of river floating garbage salvage device.
