Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to a flushing device for a secondary sedimentation tank water trough. Background Technology

[0002] In the operation of a wastewater treatment plant, the secondary sedimentation tank plays a crucial role, and the cleanliness of its flow channel directly affects the stable operation and treatment efficiency of the entire wastewater treatment system.

[0003] For a long time, the cleaning of secondary sedimentation tank water channels has mainly relied on manual washing. Especially for cement water channels, the surface is extremely prone to the adhesion of moss, algae and other aquatic plants. These deposits are not only difficult to scrub off, but also, due to their slippery nature, they cause cleaning personnel to easily slip and fall during the cleaning process, posing a significant safety hazard and threatening the personal safety of the workers. At the same time, manual cleaning is inefficient and labor-intensive.

[0004] With technological advancements, while specialized cleaning devices for removing algae from secondary sedimentation tanks have emerged, these devices suffer from significant compatibility issues. Different wastewater treatment plants have vastly different sizes of secondary sedimentation tank troughs. Even within the same secondary sedimentation tank, variations in construction processes can lead to substantial differences in dimensions at different locations. Existing scrubbing devices are often designed and manufactured to specific dimensions, making them ill-suited to such complex and varied dimensional conditions. This necessitates custom-designed devices based on the precise shape and dimensions of the secondary sedimentation tank in practical applications. This not only significantly increases purchase costs, burdening wastewater treatment plants, but also hinders large-scale production for manufacturers, negatively impacting production organization and cost control, thus severely restricting the widespread application and promotion of such cleaning devices in the wastewater treatment industry. Therefore, there is an urgent need for a versatile, efficient, and convenient flushing device that can adapt to secondary sedimentation tank troughs of varying sizes to address these problems. In light of this, we propose a secondary sedimentation tank trough flushing device. Utility Model Content

Through its unique design of first contracting and then expanding, the speed of the water flow is effectively increased, thereby generating a greater impact force and further optimizing the flushing effect.
