[0002] Circulating water mainly has two types: industrial and household, and the main purpose is to save water. Industrial water mainly includes boiler water, process water, cleaning water, cooling water, sewage, etc. Referring to the Chinese patent with the publication number "CN219730725U", "An industrial circulating water purification treatment device", this patent points out that during the use of industrial circulating water, continuous circulation in the pipeline will inevitably bring small insoluble particulate impurities, which will also affect the quality of industrial circulating water. Moreover, during the daily maintenance of industrial circulating water, bactericides and algaecides containing metal salts such as calcium and magnesium are added, which will also affect the water quality of industrial circulating water, causing problems such as water quality hardening, resulting in a decreasing utilization rate of industrial circulating water. However, this device still has the problem of poor maintenance convenience and is not convenient for replacing the filter cotton core. Therefore, we propose a multifunctional purification treatment device for circulating water to solve the above problems. Summary of the Invention

[0029] Please refer to Figures 1-8 , the present invention provides two technical solutions, specifically including the following embodiments:

[0030] Embodiment 1:

[0031] In the embodiment of the present invention, a multi-functional purification treatment device for circulating water includes a machine body 1. A liquid inlet pipe 2 is fixedly installed on the side of the machine body 1 for conveying circulating water. A primary filter box 7 is fixedly installed inside the machine body 1;

[0032] A bearing plate 13 is fixedly installed inside the machine body 1, and a driving shaft rod 14 is rotatably connected inside the bearing plate 13. A plurality of limiting ring sleeves 1401 are fixedly installed on the outer side of the driving shaft rod 14, and filter cartridges 15 are slidably installed up and down inside the limiting ring sleeves 1401. A filter cotton core 1502 is installed inside the filter cartridge 15, and the filter cotton core 1502 is used for filtering the circulating water;

[0033] A blanking pipe 11 is fixedly installed at the bottom of the primary filter tank 7, and an adapter pipe 1101 is slidably sleeved at the end of the blanking pipe 11. An adapter sleeve 1501 adapted to the adapter pipe 1101 is fixedly installed at the top of the filter cylinder 15. An annular notch 16 is formed inside the bearing plate 13. The annular notch 16 is coaxial with the adapter pipe 1101, and a drain pipe 3 is connected to the outside of the annular notch 16. After the filter cotton core 1502 inside the filter cylinder 15 is replaced, as the adapter pipe 1101 moves downward and inserts into the adapter sleeve 1501, the filter cylinder 15 can be forced to move downward into the annular notch 16. An adapter hole 1503 adapted to the drain pipe 3 is formed on the outside of the filter cylinder 15 for discharging the circulating water through the drain pipe 3;

[0034] During filtration, the sterilized circulating water can enter the inside of the filter cylinder 15 through the blanking pipe 11 and the adapter pipe 1101, so that the circulating water can be discharged through the drain pipe 3 after being filtered by the filter cotton core 1502;

[0035] A driving cylinder block 12 is fixedly installed at the bottom of the primary filter tank 7. A driving ring 1102 is fixedly installed on the outside of the adapter pipe 1101, and the piston end of the driving cylinder block 12 is fixedly connected to the driving ring 1102;
