The cover plate 4 of the utility model is provided with a connecting slot 105 for mutual engagement with an external bearing device.
[0046] Working principle: The filtering process of the utility model is:
[0047] Water inlet stage: sewage first enters the filter cavity 104 through the water inlet 102 of the upper shell 1. The water inlet joint 103 ensures a sealed connection with the external pipe to avoid sewage leakage, and is convenient for installation and subsequent maintenance. After the water flows through the water inlet joint 103, it begins to be evenly distributed in the filter cavity 104. This design helps to improve the efficiency and effect of the entire filtering process.
[0048] Primary filtration: Function of filter material A6: As the primary filtration layer, filter material A6 (fiber bundles, activated carbon or polyacrylonitrile fiber) begins to play a role, mainly removing larger particles, suspended matter, organic pollutants and adsorbing harmful substances in the water, such as some heavy metal ions and organic compounds. This layer of filtration is the foundation and lays a clean foundation for subsequent steps. Filter cover 5 assists: Filter cover 5 not only fixes filter material A6, but its mesh structure also helps to evenly distribute the water flow, while also having a certain interception effect on smaller particles, further optimizing the primary filtration effect.
[0049] Next, the water flows through the anion resin layer 12, which removes anion pollutants such as heavy metal ions in the water through ion exchange, further purifying the water quality. The filter paper 11 layer arranged above the resin layer can effectively intercept fine particles and prevent them from entering the resin layer, thereby protecting the resin layer from pollution and clogging and extending the service life of the resin layer.
[0050] The sewage then passes through the lower shell 2 and enters the cavity where the filter material B7 is located. As a secondary filter layer, the filter material B7 continues to purify the water and further removes finer particles. The filter material C8 (quartz sand or ceramic beads) filled in the internal cavity of the filter material B provides a deeper level of filtration. These materials can effectively remove finer suspended matter and further improve the purity of the effluent.
[0051] In the utility model, the filter 9 below the filter material B7 optimizes the water flow distribution through the multiple water inlet holes 9021 on its conical head 902, so that the water flows through the filter cylinder 901 more evenly and efficiently, thereby improving the filtering efficiency and ensuring the quality of the final water output.
[0052] Water outlet stage: the water outlet 13 in the utility model is connected to the filter 9: the clean water after layer-by-layer filtration is finally discharged from the water outlet 13 of the lower shell 2, and the water outlet 13 is tightly connected to the filter 9 to ensure the continuity and quality of the water outlet.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
