Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be further clearly and completely described below with reference to the accompanying drawings and specific examples of the present invention.
Example 1:
referring to fig. 1, the filter unit includes an outer frame structure inside which the filter structure is installed, and a filter structure installed in parallel to the ground or in perpendicular to the ground.
Example 2:
referring to fig. 1, 6 and 7, the filtering unit includes an outer frame structure and a filtering structure installed inside the outer frame structure, made of stainless steel punched flat plates, and including a plurality of sets of inner frames 112 and a plurality of sets of filtering plates 14, the plurality of sets of filtering plates 14 being installed inside the plurality of sets of inner frames 112, and having a plurality of holes of the flat plates (i.e., the hole plates 111) for filtering impurities in water, the filtered water flowing into the cavities of the filtering plates 14 through the holes of the filtering plates 14. In addition, the outer surfaces of the plurality of sets of filter plates 14 are smooth, so that the crushed slag can fall off along the surfaces of the flat plate type filter plates under the action of gravity, and the crushed slag is not easy to deposit on the surfaces of the filter units. In addition, in the present embodiment, the arrangement of the plurality of filter plates 14 of the filter unit is flexible according to installation space characteristics, and may be in a form of being installed perpendicular to the ground (see fig. 2) and a form of being installed parallel to the ground (see fig. 3).
The outer frame structure comprises a fixing flange 11, a first outer frame 12, a second outer frame 13, a limiting plate 15, a third outer frame 16 and a sealing plate 17.
The fixing flange 11 is fixedly connected (e.g., welded) to the first outer frame 12 and serves to mount the filter unit on a corresponding counterpart.
The first outer frame 12 and the third outer frame 16 are opposed to each other, the second outer frame 13 connects the first outer frame 12 and the third outer frame 16, and the first outer frame 12, the second outer frame 13, and the third outer frame 16 are fixedly connected (e.g., welded connection). In the embodiment, the outer frame structure is welded by section steel materials into a whole for supporting the filtering structure, and the structure is compact, so that the strength and the rigidity of the whole filtering unit can be ensured.
One of the first outer frame 12 and the third outer frame 16 (for example, the third outer frame 16) is sealed with a cover plate 17. In this embodiment, when the filter structure is installed perpendicular to the ground, the sealing plate 17 can block the debris from directly entering the gaps between the adjacent filter plates 14, and prevent the debris from depositing in the gaps between the adjacent filter plates 14.
