Description

Technical Field

[0001] The utility model relates to the technical field of multi-media filters, in particular to a multi-media filter auxiliary structure that reduces filtering resistance. Background Art

[0002] Multi-media filter is a process that uses two or more filter media to pass sewage with high turbidity through a certain thickness of granular or non-granular material, thereby effectively removing suspended impurities and clarifying the water. The principle is that when the raw water passes through the filter material from top to bottom, the suspended matter in the water is intercepted by the surface of the filter layer through interception, precipitation, diffusion and hydrodynamic action; when the water flows into the middle of the filter layer, the sand particles in the filter layer are arranged more tightly, so the particles in the water have more opportunities to collide with the sand particles, so the flocculants, suspended matter and sand particles in the water adhere to each other, and the impurities in the water are retained in the filter layer, thereby obtaining clear water quality.

[0003] During use, the existing multi-media filter does not have a buffer mechanism at the filter screen. When the fluid impact force is large, the filter screen will be damaged and noise will be generated. In addition, the fluid inlet end contains a large amount of impurities, which can easily cause the filter screen to be blocked, resulting in increased filter resistance and reduced fluid flow through the channel, affecting the subsequent filtration effect. Therefore, the utility model proposes a multi-media filter auxiliary structure that reduces the filtration resistance to solve the above problems. Utility Model Content
