They are characterized by high capacity, wide application areas (environmental), and long cycle life, making them a new energy product.

[0003] Electrolyte storage tanks vary in shape, so a corrugated pipe must be used in conjunction with a straight pipe. Both types of pipes are made of PVC, which is highly resistant to acid and alkali corrosion from electrolytes. However, the pipes can only transport the liquid and cannot filter out impurities and garbage in the liquid passing through the pipes, which increases the probability of pipe blockage.

[0004] A public announcement (publication) number CN221618801U discloses a corrugated pipe filter. The technology disclosed herein "includes a bellows and a slip-on flange, a filter is provided inside the bellows, and a fixing ring is provided at one end of the filter. The filter has a small internal space and does not occupy additional space. It can be directly installed inside the pipe, making installation and removal convenient. This design enables the filter to fit more closely to the pipe, reducing the flow resistance of the liquid in the pipe and improving the efficiency of fluid transmission, among other technical effects."
