The top of the rotating shaft 304 is installed with a scraper rod 305. A pure chamber 4 is arranged below the filter plate 303, and the diameter of the filter plate 303 is consistent with the inner diameter of the purification tank 2. A supporting bottom plate 5 is arranged at the bottom of the pure chamber 4, and a liquid outlet pipe 6 is installed in the middle of the supporting bottom plate 5. The liquid outlet pipe 6 discharges the urotropine that reduces the iron ion content.

[0024] Embodiment 2

[0025] See also Figure 2The outside of the reaction tank 1 is provided with an adjustment component 7 for adjusting the height position, and the number of adjustment components 7 is set in two groups. The adjustment component 7 includes a cushion block 701 and a hydraulic rod 702, and the upper end of the cushion block 701 is installed with the hydraulic rod 702. The telescopic control of the hydraulic rod 702 allows the reaction tank 1 to be lifted and lowered inside the top of the purification tank 2 to complete the opening and closing control of the bottom of the purification tank 2.
