Description

Technical Field

[0001] This utility model relates to a sewage treatment device that is easy to clean, and belongs to the field of sewage treatment technology. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] The existing patent number CN220034284U describes a wastewater treatment device that is easy to clean. This device uses a flushing nozzle to move and wash away dirt with high-pressure water, then a spiral conveyor transports the dirt to a storage tank for storage, ensuring the filtration effect of the filter screen and offering the advantage of easy cleaning. A servo motor drives a worm gear to rotate, which in turn drives a stirring rod to mix the wastewater and chemicals. An electric nozzle delivers chemicals from the chemical tank to the mixing tank, facilitating wastewater treatment. However, this device requires wastewater to be directly injected into the casing for mixing during operation. The method of mixing the chemicals directly with the wastewater before discharge results in the wastewater passing through the filter screen during injection, which cannot guarantee sufficient mixing with the chemicals and thus affects the wastewater treatment effect. Furthermore, the flocculent material on the upper side tends to adhere to the side wall of the casing, while the bottom nozzle cannot rinse the side wall, affecting the cleaning effect of the wastewater treatment equipment. Moreover, the method of directly rinsing the filter screen with the bottom nozzle during use can easily cause impurities and flocculent material to become embedded in the mesh of the filter screen, which cannot guarantee the effective removal of flocculent material and impurities and affects the subsequent use of the filter screen. In addition, the conveying method using the spiral conveyor rod is difficult to effectively remove water-containing impurities. Utility Model Content

Inside, on the upper side, the filtered water is discharged through the drain valve and drain pipe. The rotating water guide pipe and the water guiding action enable the rotating spray head to rotate. After sewage treatment, the rotation of the rotating handle moves the locking bolt forward, causing the turntable to rotate. This causes the rotating filter frame to rotate and the filter screen to flip, allowing the rotating spray head to perform a reverse rinsing of the flipped filter screen. After opening the third solenoid valve, sewage containing flocculents and impurities can enter the filter collection box through the drain pipe. The collection frame collects the flocculents and impurities, while the filtered clean water is discharged through the clean drain pipe. Pulling the pull-out frame allows the collection frame to be removed for quick cleaning of impurities and flocculents, improving the convenience of internal cleaning of the sewage treatment equipment.
