[0002] A mercerizing machine typically consists of a fabric feeder, an alkali soaking tank, a width spreading device, a rinsing device, and a leveling tank. The working principle of a mercerizing machine is to treat the fabric with a concentrated caustic soda solution, causing the fibers in the fabric to swell and soften. Then, through treatment with specific tension and temperature, the fabric achieves a smooth and lustrous finish.

[0003] In existing technologies, such as the document with publication number CN222251346U, an alkaline solution impurity removal device for a mercerizing machine is specifically disclosed. In this device, the alkaline solution in the alkali soaking tank is transported to the filter box by a second water pump, and the alkaline solution is filtered and impurities are removed by the filter belt in the filter box. However, although the filter belt in this device can filter the alkaline solution, it mainly relies on the gravity of the alkaline solution, which results in a slow filtration speed and low filtration efficiency.

[0015] 2. The second water pump extracts the alkaline solution from inside the filter box through the return water pipe and injects the alkaline solution into the smaller space between the alkali soaking box and the screen through the water injection pipe.
