[0002] In the industrial sewage treatment system, because the residues in the sewage agglomerate and become sludge, it is necessary to use a mud scraper. Specifically, a large mud scraper is installed in the sewage tank. The mud scraper rotates and scrapes the wall and bottom of the sewage tank. Due to the high content of oil sludge in industrial sewage, it is necessary to start the sludge scraper frequently, which not only costs a lot but also reduces the life of the sludge scraper; there is a pre-sludge filter equipment on the market, but Due to the high content of oily sludge, the filter parts need to be replaced frequently, and the replacement operation is inconvenient; in order to make the filter parts recyclable, it is necessary to separate the oily sludge in the filter parts. Chemical treatment, not only the separation operation is inconvenient, but also the cost is high

Embodiment 1
[0029] see Figure 1-4, an industrial sewage environmental protection treatment device, comprising a fixed support plate 1, the fixed support plate 1 is horizontally distributed and holds a horizontally distributed filter mud cylinder 2, and the filter mud cylinder 2 is filled with particles, and the particles can be stones or It is a material that is easy to block the flow of sludge such as ceramsite. The cost of such materials is low. The external industrial sewage containing sludge and small particles of impurities after the impurity removal treatment enters the filtered mud cylinder through one end of the filter cylinder 2. Filtration of the particulate matter filled in 2, the sewage containing lower sludge is discharged through the other end of the filter cartridge 2, and the filter cartridge 2 and the fixed pallet 1 are rolled in a rolling fit. Specifically, the outside of the filter cartridge 2 is sleeved with The rotating sleeve 21 located at both ends, the rotating sl...

The invention discloses an environmental protection treatment device for industrial sewage, comprising a fixed support plate which is horizontally distributed and holds a horizontally distributed filter mud cylinder, the filter mud cylinder is filled with particles, and the filter mud cylinder is filled with particles. The mud cylinder is in rolling fit with the fixed support plate, the bottom of the fixed support plate is rotatably connected with a switching frame, and the rotation axis is parallel to the axis of the mud filter cylinder. In the present invention, a fixed support plate is arranged, a filter mud cylinder is supported above the fixed support plate, a switch frame is rotatably connected below the fixed support plate, and a butt pipe is detachably connected to both ends of the filter mud cylinder on the switch frame, wherein The two ends of the switch frame are provided with limit brackets. When the sludge accumulation in the filter cartridge reaches a certain amount, the switch frame rotates and tilts. At this time, the filter cartridge can be separated and pushed to the limit bracket. , in the same way, the spare filter cartridge on another limit pallet can be transported to the docking pipe, which has the function of convenient replacement of the filter cartridge.
Description
technical field [0001] The invention relates to the technical field of industrial sewage treatment, in particular to an environmental protection treatment device for industrial sewage. Background technique [0002] In the industrial sewage treatment system, because the residues in the sewage agglomerate into sludge, it is necessary to use a sludge scraper. Specifically, a large sludge scraper is installed in the sewage tank, and the sludge scraper rotates to scrape the sewage tank wall and tank bottom. Due to the high content of oil sludge in industrial sewage, it is necessary to frequently start the sludge scraper, which not only costs high but also reduces the life of the sludge scraper. Currently, there is a pre-sludge filtration equipment on the market, but Due to the large oil sludge content, the filter parts need to be replaced frequently, and the replacement operation is inconvenient; in order to recycle the filter parts, the oil sludge in the filter parts needs to be...
