ABSTRACT:
An exemplary apparatus (100), for removing buoyant pollutants from a polluted coolant, includes a collecting device (10) and a removing device (20). The collecting device includes a pollutant collecting structure (11) and a bi-directional pump (12). The pollutant collecting structure includes a hollow tub (112) and a collecting module (113) slidable relative to the hollow tub. The bi-directional pump communicates with the hollow tub and the removing device. The removing device includes a filter (21) and a pollutant removing structure (22) disposed on the filter. The filter includes a filtrating unit (211). The filtrating unit is partitioned into a first cavity (2132) and a second cavity (2133) by a partition sheet (213). The partitioning board defines a communicating gap (2131) for the first cavity and the second cavity to communicate with each other. The pollutant removing structure includes a removing member (221) for removing the buoyant pollutants out of the filter.
