Document Type and Number:
WIPO Patent Application WO/2019/061868
Kind Code:
A1
Abstract:
A slag dredging device, comprising a slag dredging filter screen (1), a filter screen frame (2), and two guide rails (3) arranged in parallel. The filter screen frame (2) comprises an outer frame (14) and an inner frame (15), and a circumferential mounting area is formed between the outer frame (14) and the inner frame (15). The opening of the slag dredging filter screen (1) is installed in the mounting area. The filter screen frame (2) is disposed between the two guide rails (3) arranged in parallel, and the two side frames of the filter screen frame (2) are respectively slidably connected to the guiderails (3). By providing the slag dredging device in a wastewater discarding well, a distributing well or an intercepting well, pollutants in sewage can be effectively intercepted; moreover, due to the presence of a baffle (5), floating objects do not need to be collected manually, thereby saving manpower. All the intercepted pollutants are lifted up by a lifting apparatus (4) and are collectively and uniformly treated, thereby effectively preventing the blockage of the wastewater discarding well, the distributing well or the intercepting well and the pollution of the natural water body.
