[0017] The present application is a kind of central heating system pipe network filtration and blow-off equipment, which combines the advantages of the prior art and has the following beneficial effects. Figure 1As shown, the device includes a housing 1, with a water inlet 2 at the top of the housing 1 through which hot water flows into the housing 1. Several magnetic rods 5 are detachably mounted on the top of the side wall of the housing 1. The magnetic rods 5 are horizontally inserted into the top of the housing 1 and staggered, and are used to adsorb conductive impurities in the hot water. A water collecting port 9 is located below the magnetic rods 5. The water collecting port 9 is funnel-shaped and connected to the inner side wall of the housing 1. A filter cylinder 10 is connected to the bottom of the water collecting port 9. The filter cylinder 10 is longitudinally installed through the bottom of the housing 1 and is used to filter the hot water. A clear water chamber 11 is formed between the filter cylinder 10, the water collecting port 9, and the housing 1. The clear water chamber 11 is used to hold the filtered hot water. A water outlet 3 is located at the bottom of the side wall of the housing 1. The water outlet 3 is connected to the clear water chamber 11 and is used to discharge the filtered hot water.

[0018] A stepped hole 7 is provided on the top of the side wall of the housing 1. The stepped hole 7 includes a first stepped hole and a second stepped hole opened sequentially from the inside to the outside. The diameter of the second stepped hole is larger than that of the first stepped hole. The outer diameter of the magnetic rod 5 is smaller than that of the first stepped hole, so that conductive impurities adsorbed on the magnetic rod 5 can be easily removed through the stepped hole 7. A connecting plate 6 is provided at the outer end of the magnetic rod 5 near the stepped hole 7. The connecting plate 6 is adapted to the second stepped hole and is detachably connected to the housing 1 by a fixing bolt 8 that is threaded through and connected to the first stepped hole. A sealing ring is provided between the stepped hole 7 and the connecting plate 6 to achieve a seal. A limiting seat 4 is provided on the inner side wall of the housing 1 at a position opposite to the inner end of the magnetic rod 5. The limiting seat 4 is used to insert the inner end of the magnetic rod 5, thereby positioning the magnetic rod 5 within the housing 1.

[0019] The bottom end of the housing 1 is provided with a drain port 12, which is funnel-shaped and connected to the filter cylinder 10. The dirt in the filter cylinder 10 can be discharged through the drain port 12. A drain valve 15 is provided on the drain port 12, which is used to control the opening and closing of the drain port 12, thereby realizing the drain control.

[0020] A forward flushing port 13 is provided on the side wall of the housing 1, connecting to the top of the filter cartridge 10. The forward flushing port 13 is used to connect to external cleaning water, thereby achieving forward flushing of the filter cartridge 10. A forward flushing valve 16 is provided on the forward flushing port 13, which controls the opening and closing of the forward flushing port 13. A reverse flushing port 14 is provided on the side wall of the housing 1, connecting to the clean water chamber 11. The reverse flushing port 14 is used to connect to external cleaning water, thereby achieving reverse flushing of the filter cartridge 10. A reverse flushing valve 17 is provided on the reverse flushing port 14, which controls the opening and closing of the reverse flushing port 14. When the filter cartridge 10 needs cleaning, stop the hot water supply to the equipment, close the drain port 12, open the forward flushing valve 16 and the reverse flushing valve 17, and connect the forward flushing port 13 to external cleaning water to achieve forward flushing of the filter cartridge 10. The cleaning water carrying impurities flows out from the reverse flushing valve 17. Alternatively, close the forward flushing valve 16, open the drain port 12, open the reverse flushing valve 17, and connect the reverse flushing valve 17 to external cleaning water to achieve reverse flushing of the filter cartridge 10. The cleaning water carrying impurities flows out from the drain port 12. Thus, through forward and reverse flushing, the filter cartridge 10 can be cleaned without removal.

[0021] In use, this invention is installed on the main pipeline of a centralized heating system via inlet 2 and outlet 3. Hot water flows in from the top of the casing 1 through inlet 2. Conductive impurities such as iron filings in the hot water are adsorbed onto the magnetic rod 5. The hot water, now free of conductive impurities, flows into the filter cartridge 10 for filtration. The filtered hot water then flows into the clear water chamber 11 and returns to the main pipeline of the centralized heating system via outlet 3 for further heating. When the magnetic rod 5 needs to remove adsorbed conductive impurities, the flow of hot water into the device is stopped, the magnetic rod 5 is removed, the adsorbed conductive impurities are removed, and it is then reinstalled. When the filter cartridge 10 needs cleaning, the flow of hot water into the device is stopped, and forward and reverse flushing are performed by connecting an external water source through the forward flushing valve 16 and reverse flushing valve 17.
