AI Technical Summary
In existing heat exchangers, impurities tend to accumulate on the inner wall of the pipes when the fluid flows through them. Conventional structures are difficult to effectively intervene, and long-term accumulation leads to blockage, affecting heat exchange efficiency. Frequent manual disassembly and cleaning are required, which accelerates equipment aging, and the sewage discharge process is complicated and inconvenient.
The spiral blade design causes the fluid to rotate and flow, which, combined with the filter screen, blocks impurities. The water flow drives the cleaning rod to clean the filter screen, and the spring telescopic rod keeps the cleaning rod in place. Combined with the water flow, it achieves all-round cleaning, and the impurities are discharged through the drain pipe.
It effectively reduces impurity buildup, ensures smooth flow, improves heat exchange efficiency, extends equipment life, simplifies cleaning operations, and ensures a clean internal environment for the equipment.
