Technical Field

[0001] The utility model belongs to the technical field of filtering and water purification devices, and particularly relates to a multi-media filtering and water purification device. Background Technique

[0002] A multi-media filter is a process of using one or several filtering media to pass water with a relatively high turbidity through a certain thickness of granular or non-granular materials under a certain pressure, so as to effectively remove suspended impurities and clarify the water. Commonly used filter materials include quartz sand, activated carbon, manganese sand, etc. It is mainly used for pre-treatment of water treatment for turbidity removal, water softening and pure water, and the effluent turbidity can reach below 3 degrees.

[0003] The existing multi-media filtering and water purification device generally consists of a shell, multiple filter material layers and multiple partition nets. When in use, the multiple filter material layers are separated by the multiple partition nets respectively, and the multiple partition nets are fixedly connected to the inner wall of the outer shell, resulting in a scattered distribution state of the filter materials when multiple filter materials need to be replaced. It is rather troublesome to take them out and multiple partition nets need to be disassembled and assembled, and the operation is inconvenient. Summary of the Invention

[0007] In order to facilitate accurate positioning of the installation position of the top cover, as a preferred multi-media filtering and water purification device of the utility model, a positioning groove is opened at the upper end of the outer shell, and a positioning ring extending into and matching with the positioning groove is fixedly connected to the lower end of the top cover.

[0008] To facilitate the sealing of the housing and the top cover, as an optimization of the multi-media filtration water purification device of the present utility model, a sealing ring that presses against the lower end of the positioning ring is installed inside the positioning groove.

[0009] To facilitate lifting the three separation mesh plates together with the manganese sand filter material ring, activated carbon filter material ring, and quartz sand filter material ring, as an optimization of the multi-media filtration water purification device of the present utility model, lifting handles are fixedly connected to the upper ends of the three separation mesh plates.

[0013] When the present utility model is in use, manganese sand, activated carbon, and quartz sand are respectively filled into the manganese sand filter material ring, activated carbon filter material ring, and quartz sand filter material ring. Then, through the multiple positioning rods and multiple positioning holes, the manganese sand filter material ring, activated carbon filter material ring, and quartz sand filter material ring can be positioned and stacked in sequence from bottom to top. Next, the positioning ring is inserted into the positioning groove, and then the two screw rods are rotated into the two limiting frames and tightened downward, so that the limiting mesh plate can be abutted against the upper end of the quartz sand filter material ring, completing the limiting and fixing of the manganese sand filter material ring, activated carbon filter material ring, and quartz sand filter material ring. When it is necessary to take out the filter material, only need to remove the top cover in the reverse steps, and take out the quartz sand filter material ring, activated carbon filter material ring, and manganese sand filter material ring in sequence, so that the filter material inside can be replaced, and the operation is convenient.
