Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a scum lifting device for a sewage treatment primary sedimentation tank. Background Art

[0002] The primary sedimentation tank is an important part of sewage treatment, mainly used to remove the settleable and floating materials in the wastewater. Its main function is to flocculate fine solids into larger particles through physical sedimentation, and then separate them from the wastewater. The setting of the primary sedimentation tank helps to reduce the organic load of the subsequent biological treatment structure and improve the activity of microorganisms in the activated sludge.

[0003] After the scum in the primary sedimentation tank has accumulated for a period of time, the workers will use the filter residue to lift and clean the scum inside it, so as to remove the scum accumulated in the primary sedimentation tank. However, the above working method is inefficient when used and has high labor costs. Therefore, the prior art proposes a scum well lifting device for the primary sedimentation tank of sewage treatment, and the patent publication number is CN215538674U. When the above patent is in use, a drive box is provided, and a motor B is installed in the drive box, and moving blocks are set on both sides of the outer wall of the motor B, so that the starting motor B drives the moving block to move left or right, and the scum in the well is cleaned by arranging a pipe mouth and a receiving net on the moving block, thereby realizing the cleaning of the scum in the primary sedimentation tank. At the same time, the winding roller is driven by the motor A, so that the cable lifts the scum out of the wellhead, thereby realizing the lifting treatment of the scum well in the primary sedimentation tank.

[0004] However, when the above patent is used, the mesh is often clogged due to the complex composition of the scum inside, which results in a large amount of sewage mixed inside the scum when lifting the scum, increasing the overall mass, thereby increasing the lifting burden of the machine, and the sewage occupies most of the space of the receiving net, affecting the efficiency of scum salvaging. In order to solve the above problems, while facilitating the cleaning of the scum in the primary sedimentation tank, it is convenient to discharge the excess sewage inside, thereby improving the scum salvaging efficiency. For this reason, we propose a scum lifting device for the primary sedimentation tank of sewage treatment. Utility Model Content
