[0020] The water inlet filtration mechanism includes a shell 9 and a filter cartridge 10 coaxially arranged in the shell 9. The shell 9 includes an upper shell fixed in the main water tank 1 by a hanging rod and a lower shell screwed to the lower edge of the upper shell. The inner diameter of the lower shell is larger than the inner diameter of the upper shell, which is conducive to the temporary storage of impurities. The energy storage water tank 3 is connected to a water inlet pipe 11 connected to the inner cavity of the shell 9. The outlet of the water inlet pipe 11 is coaxially arranged above the filter cartridge 10. The top surface of the filter cartridge 10 is coaxially provided with a guide cone 12. The filter cartridge 10 is connected to a water outlet pipe 13 extending to the outside of the main water tank 1. The booster pump is provided on the water outlet pipe 13. The lower end of the water outlet pipe 13 is connected to an annular water distribution pipe 14;

[0021] The water wheel mechanism includes a turntable 15 coaxially arranged in the main water tank 1, and a stirring blade ring group 16 and an impact blade ring group 17 are arranged on the bottom surface of the turntable 15. The stirring blade ring group 16 includes a plurality of stirring blades uniformly distributed circumferentially on the bottom surface of the turntable 15, and the impact blade ring group 17 includes a plurality of impact blades uniformly distributed circumferentially on the bottom surface of the turntable 15. The impact blade ring group is close to the outer ring of the turntable 15. The annular water distribution pipe 14 is connected to a plurality of oblique nozzles 18 extending into the main water tank 1, and the oblique nozzles 18 face the impact blades. The blade ring group 17 is hit, and the axis of the oblique nozzle 18 is close to the tangent of the turntable 15. Multiple oblique nozzles 18 jointly drive the turntable 15 to rotate. A rotating shaft is also coaxially fixed on the top surface of the turntable 15. The rotating shaft includes a lower shaft 19 and an upper shaft 20 screwed to the upper end of the lower shaft 19.

[0022] The working principle of this embodiment is:

[0023] Sewage flows in from the sewage inlet pipe 4 and flows out from the sewage outlet pipe 5. The peristaltic pump 2 pumps the sewage in the main water tank 1 into the energy storage tank 3 according to the frequency. The water out of the energy storage tank 3 enters the outer shell 9. Since the energy storage tank 3 is higher, the sewage has gravitational potential energy, so the outer shell 9 will be filled with pressurized water flow, realizing the forced injection of sewage into the filter cartridge 10, ensuring sufficient water supply to the booster pump. The water flow filtered by the filter cartridge 10 is pumped into the annular water distribution pipe 14 through the booster pump. The filter cartridge 1 can effectively protect the booster pump and extend the service life of the booster pump; the water flow entering the annular water distribution pipe 14 is ejected through the inclined nozzle 18 and drives the turntable 15 to rotate. When the turntable 15 rotates, the stirring blade The ring group 16 disturbs the water flow on the bottom inner surface of the main water tank 1 to prevent the deposition of impurities such as mud and sand. When the turntable 15 rotates, it drives the rotating shaft to rotate. The rotating shaft drives the brush rod 21 and the brush 22 to circulate and brush the outer surface of the filter cartridge 10 to prevent impurities from clogging the filter cartridge. After running for a period of time, the machine is stopped. First, the lower shell is screwed off, and then the upper shaft 20 is screwed off. The upper shaft 20 is taken out together with the lower shell to clean the impurities and then put back. Compared with the prior art, this embodiment can produce an internal circulation effect of sewage in the main water tank 1, avoid the deposition and clogging of mud and sand impurities, significantly improve the continuous operation time of sewage heat energy recovery in the hot water mixing tank, reduce the workload of inspection and maintenance, and has strong practicality.
