Embodiment 1
[0039] Such as Figure 1-8 As shown, a kind of sedimentation sludge cleaning device for sewage treatment of the present invention comprises a walking frame device, a U-shaped buckle cover 1, a buckle cover lifting device, a mud scraper 2, an agitating brush 3 and a mud scraper drive motor 4. The walking frame device is erected above the sedimentation tank 6, the cover lifting device is arranged on the walking frame device, and the four lifting screw rods 7 of the cover lifting device are connected to the U-shaped cover 1, and the U-shaped cover is controlled by the cover lifting device. The U-shaped button cover 1 is lifted; the U-shaped button cover 1 is made of stainless steel plate with a U-shaped structure. The height of the U-shaped button cover 1 is generally set according to the thickness of the sedimentation mud in the sedimentation tank 6. The sedimentation tank 6 mud in the block area is all sealed, and the amount of sewage is reduced as much as possible, and the wat...
Embodiment 2
[0048] Such as Figure 1-8 As shown, the present invention is a settling sludge cleaning device for sewage treatment. On the basis of Embodiment 1, this embodiment adds the function of cleaning scum, and a scum baffle is hung on one side of the walking frame device 23. The scum baffle 23 is attached to one side of the outer wall of the U-shaped button cover 1 . The scum baffle 23 is inserted in the sewage to isolate the scum on one side, so that when the U-shaped button cover 1 descends into the sewage, the scum collected on one side of the scum baffle 23 will be covered on the U-shaped button cover 1 Inside, when the sludge is subsequently sucked, the scum is sucked and removed together with the sludge, and the walking frame device continuously drives the scum baffle 23 to move in one direction of the sedimentation tank 6, so that the scum will be continuously covered by the U-shaped button 1 is covered and subsequently drawn away, and a filter screen is provided on the lowe...
Embodiment 3
[0050] Such as Figure 1-8As shown, the present invention is a settling sludge cleaning device for sewage treatment. On the basis of the above-mentioned embodiments, the walking frame device includes a walking motor 24, a pulley 25 and a support shaft 26, which are placed on the edge of the sedimentation tank 6 Guide rails 27 are laid, at least two support shafts 26 are erected on the sedimentation tank 6, pulleys 25 are provided at both ends of the support shafts 26, and the pulleys 25 are slidably arranged on the guide rails 27, and the support shafts 26 are connected and fixed by connecting rods. The traveling motor 24 is connected to at least one pulley 25 through a transmission chain, and the traveling frame device is driven by the traveling motor 24 to move on the guide rail 27 . Walking frame device is exactly a support walking frame, controls walking frame to move on setting guide rail 27 by controlling traveling motor 24.
