[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4As shown, a filtration device for purified water preparation is used in the water purification process. The water to be purified is stored inside a raw material storage tank 1. In use, the pneumatic valve 11 connected to the end of the first delivery pipe 2 can pump the water stored in the raw material storage tank 1 to a multi-media filter 3. The pneumatic valve 11 delivers water to the water collection tank 13 at the top of the multi-media filter 3, from which the water is fed into the filter tube 12. The filter tube 12 is installed on the multi-media filter 3 via a mounting bracket 15 on its outer wall. The mounting bracket 15 can be connected and fixed to the filter tube 12 using a fixing bolt 16. A filter element 14 is installed inside the filter tube 12, which performs preliminary purification filtration on the input water. The filtered water flows into the second delivery pipe 6 from the drain outlet 17. The second delivery pipe 6 feeds the water to the high-pressure pump 5 at the end. The high-pressure pump 5 is connected to the activated carbon filter via the No. 3 delivery pipe 8. Water is then fed into the activated carbon filter for secondary filtration via the high-pressure pump 5. The activated carbon filter consists of two sets of filter housings 9, each containing an activated carbon filter screen 20. Water flows into the activated carbon filter screen 20 inside the first filter housing 9 and, after filtration, is fed into the bottom activated carbon filter screen 20 through the conical funnel 19 at the bottom. This layered filtration improves the filtration effect. The filter tube 12 inside the multi-media filter 3 is installed via the mounting bracket 15. When cleaning is required, the filter tube 12 can be removed to replace the inner core. The activated carbon filter screens 20 are installed in the two sets of filter housings respectively. By assembling the housings together and using the fixed outer frame structure, the activated carbon filter screens can be installed, making the replacement of the activated carbon filter screens 20 more convenient.

[0022] Example 2, as Figures 1-4 As shown, a filtration device for purified water preparation is disclosed. The filtered purified water is discharged through a drain valve 10. A pressure sensor 21 displays the inlet and outlet pressures of the filter during system operation. The drain valve 10 is only used to discharge water from the filter at specific times. Water samples can be taken from valve 10 to test the residual chlorine value of the water produced after the activated carbon filter.
