The tangent inlet pipe 2 allows water to rotate as it enters the tank 1, and centrifugal force causes impurities in the hot water to move towards the side wall of the tank 1. The hot water, after centrifugal separation, can be filtered again through the filter cylinder 5, and finally, the filtered hot water... Water is discharged through the outlet pipe 3. A baffle 6 is fixedly installed at the bottom of the central cylinder 4. The edge of the baffle 6 is connected to the inner wall of the tank 1. Multiple connecting pipes 7 are arranged in a ring at the edge of the baffle 6. A slag discharge pipe 8 is connected to the bottom of the tank 1. Impurities separated by centrifugation and by the filter cylinder 5 can settle downwards and finally enter the storage below the baffle 6 through the connecting pipe 7 and are discharged from the tank 1 through the slag discharge pipe 8. A filter cylinder cleaning assembly is installed on the outside of the central cylinder 4. The filter cylinder 5 can be cleaned through the cleaning assembly. The multiple connecting pipes 7 can reduce the agitation of impurities below the baffle 6 by hot water.

[0018] As an embodiment of this utility model, the filter cartridge 5 cleaning assembly includes a brush 11. A pair of rotating rings 9 are rotatably arranged on the outside of the central cylinder 4. Multiple connecting rods 10 are connected to the pair of rotating rings 9. The brush 11 is fixedly installed at the bottom of the connecting rods 10. The brush 11 is in contact with the outer surface of the filter cartridge 5. The tank body 1 is also provided with a rotating ring 9 driving assembly. By driving the rotating rings 9 to rotate, the brush can rotate on the outer surface of the filter cartridge 5, thereby cleaning the filter cartridge 5.

[0019] As an embodiment of this utility model, the rotating ring 9 drive assembly includes multiple fan blades 13. The multiple fan blades 13 are fixedly installed on the outer surface of the upper rotating ring 9 by the mounting bracket 12. The water discharged from the water outlet pipe 3 can impact the fan blades 13 to make the rotating ring 9 rotate.

[0020] As one embodiment of this utility model, the partition 6 has an umbrella-shaped structure, which facilitates the sliding of impurities to the top of the connecting pipe 7.

[0021] As an embodiment of this utility model, the upper end face of the connecting pipe 7 is not higher than the upper surface of the partition 6, so that impurities above the partition 6 can smoothly pass through the connecting pipe 7 and enter below the partition 6.

[0022] As an embodiment of this utility model, a valve 14 is installed on the slag discharge pipe 8. Opening the valve 14 can discharge the impurities stored below the partition 6.

[0023] The working principle and usage process of this utility model are as follows: In use, hot water enters the tank 1 through the inlet pipe 2. Since the inlet pipe 2 is tangentially set to the tank 1, the hot water entering the tank 1 can rotate. The rotation of the hot water generates centrifugal force, causing impurities in the hot water to move towards the side wall of the tank 1. After centrifugal separation, the hot water can enter the central cylinder 4 through the filter cylinder 5 below the central cylinder 4. The filter cylinder 5 can filter the hot water again. Finally, the filtered hot water is discharged from the tank 1 through the outlet pipe 3. The separated impurities can settle downwards and enter the space below the partition 6 for storage through the connecting pipe 7. When the hot water enters the tank 1, it can impact the fan blades 13. The fan blades 13 can make the rotating ring 9 rotate, which in turn makes the brush 11 rotate on the outside of the filter cylinder 5, thus cleaning the filter cylinder 5.
