Description

Technical Field

[0001] This utility model relates to a sewage discharge mechanism and a pre-filter with a large sewage holding space and self-settling and anti-backflow features, belonging to the technical field of water purification equipment. Background Technology

[0002] Municipal tap water is often contaminated with secondary pollutants such as pipe corrosion and sediment, leading to deterioration of household water quality. Pre-filters are typically installed on the inlet pipes to improve water quality. Currently, pre-filter cartridges on the market are mainly of mesh or disc type. Cleaning methods include forward rinsing, backwashing, siphon cleaning, or brushing. However, both mesh and disc filter cartridges have limitations in their drainage structure, such as small dirt-holding space, making it difficult to clean the cartridge thoroughly. This is especially true for automatic rinsing or brushing, where impurities can easily flow back into the filter bottle. Figure 1 As shown, this restricts the cleaning effect of the filter element, shortens its service life, and makes it impossible to guarantee the water filtration quality of the pre-filter.

[0003] Therefore, it is necessary to design a structure suitable for pre-filters that can confine the impurities washed down through cleaning and rinsing by a certain space or component, preventing impurities from repeatedly flowing into the filter bottle. The researchers of this application, through structural optimization design and experimental simulation, developed a sewage discharge mechanism with a large dirt-holding space and the ability to effectively prevent impurities from settling and flowing back into the filter bottle. This mechanism was used in the design and development of a new type of backwashing pre-filter, achieving good results, significantly improving the cleaning effect of the filter element, extending the service life of the filter element, and greatly ensuring the quality of water filtration. Utility Model Content

[0004] One of the objectives of this invention is to address the shortcomings of existing pre-filter drainage structures by providing a drainage mechanism with a large dirt-holding capacity and self-settling to prevent backflow. This drainage structure is optimized, expanding the dirt-holding capacity, and through the design of the backflow element, it prevents impurities washed down from flowing back into the filter bottle, ensuring the effectiveness of each cleaning.

[0005] The second objective of this utility model is to provide a pre-filter with a large dirt-holding space and a self-falling sedimentation and anti-backflow sewage discharge mechanism.
