[0050] The working principle of the solid-liquid separator with a rotary spraying device in the utility model:

[0051] As attached Figure 5 As shown, when the solid-liquid separator with a rotary spraying device is in use, water is directly pumped into the spray pipe through a water pump, and the water flows directly through the spray pipe for a one-time spraying work. The water pump is connected to the water storage tank to ensure stable water supply. The flocculation mixing tank is equipped with a liquid level switch and a high liquid level gauge. When performing a one-time spraying, ensure that the water consumption is sufficient and the water pressure is controlled to ensure that the water pressure during the spraying operation can meet the use requirements. After the spraying work is completed, water will be automatically added to fill it up to prepare for subsequent spraying work. The water storage tank is arranged in the flocculation mixing tank to make full use of the space in the corners around the flocculation mixing tank. In addition, there is no stirring dead corner at the bottom of the flocculation mixing tank.

[0052] As attached Figure 2 As shown, the direct drive of the solid-liquid separator or an external drive device is used as the power source of the rotating power source, so that the driving rod in the rotating power source drives the corresponding spray pipe to rotate through the transmission assembly, and the paired half gears on the driving rod cooperate with the gears on the driven rod. The gears on at least one driven rod are used as transmission parts. The pulley on the driven rod can drive the spray pipe to rotate 360 ​​degrees through the transmission belt. The plurality of spray pipes are synchronously linked and rotated through the transmission belt to clean the solid-liquid separation filter body, and the sweeping spray effect is more ideal.

[0053] The spray pipes provided on the solid-liquid separation filter body can switch between forward and reverse rotation according to the spraying needs. The driving rod is used as the power output shaft. The driving rod and the driven rod cooperate with each other to achieve high transmission efficiency, so that the rotation synchronization rate between several spray pipes can be guaranteed, thereby ensuring the spraying effect of the spray pipes during work. The detachable driving rod and driven rod greatly meet the needs of easy maintenance of the rotary spray mechanism in the later stage.

[0054] As attached Figure 2 As shown, when the transmission assembly uses a transmission belt, the pulley provided on one side of the gear on the driven rod can drive the pulley provided on one end of the spray rod through the transmission belt to work in linkage;

[0055] When the rotation synchronization rate of the spray pipe needs to be adjusted, the tension of the transmission belt responsible for the transmission work can be fine-tuned by adjusting the position of the tensioning wheel in the transmission belt to adjust the tension of the transmission belt. When the tension of the transmission part is adjusted, the position of the tensioning wheel can be re-fixed.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
