| 摘要 |
The present invention refers to an arrangement able to remove the impurities from a liquid surface. The impurities are hauled by surface liquid which is transferred to suction pipe (2) through one or various devices (Fig. 5) disposed in a serial, parallel or another geometric or irregular form. The haulage of the impurities from liquid surface occurs because the pump causes a low pressure zone which remains throughout suction pipe (2) and pieces (3 and 4), causing a changing level of the liquid inside all pieces (4). This changing level causes continuous fall, by gravity, of the surface liquid with impurities in it into all the pieces (4) through the nozzles (6), and from suction pipe (2) said surface liquid is transferred, for example to filtering system in case of solids in suspension, or to separator system in case of immiscible fluids, or to processing. |
