The utility model discloses an adsorbent belt cleaning device. This adsorbent belt cleaning device, including the staving, the lower part of staving is provided with the outlet, and drain connection has the drain pipe, installs foraminiferous baffle at the upside of outlet, and the baffle that highly is higher than of arranging water outlet of the water pipe is less than reason on the staving, still includes the gland, and the gland diameter is less than the internal diameter of staving, and the adsorbent is placed between baffle and gland. Gland in the last side pressure of baffle is placed to the adsorbent, can place the heavy object on the gland, and to putting into the clean water in the staving, the adsorbent has recovered the adsorption efficiency by reuse under the recycling of water washes. This device does not need the manual work to remove to step on the pressure adsorbent, has reduced workman's intensity of labour, has avoided simultaneously because extrusion and to the damage that the adsorbent caused yet, has improved the life of adsorbent, has reduced manufacturing cost.
