Embodiment 1

[0039] like 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 water ...

Embodiment 2

[0048] like 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 lower w...

Embodiment 3

[0050] like 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.

Abstract

The invention discloses a precipitated sludge cleaning device for sewage treatment. A walking frame device is arranged above a sedimentation tank; a buckle cover lifting device is arranged on the walking frame device; four lifting screw rods of the buckle cover lifting device are connected to a U-shaped buckle cover; the U-shaped buckle cover is controlled to lift by the buckle cover lifting device; the U-shaped buckling cover capable of being controlled to be opened and closed is adopted; the U-shaped buckle cover is controlled to be conveyed to the bottom of a specified sedimentation tank through the walking frame device and the buckle cover lifting device; precipitated sludge at the bottom of the sedimentation tank is sealed in the U-shaped buckling cover; then, sludge at the bottom ofthe sedimentation tank is scraped off through a sludge scraper; the sludge blocks form slurry under the stirring of a stirring brush; when the sludge is scraped off and stirred, the sludge is continuously pumped out by a suction pump, then the sludge is dewatered, therefore the precipitated sludge at the bottom of the sedimentation tank is removed, and then the U-shaped buckling cover is controlled by the walking frame device and the buckling cover lifting device to be transferred to a non-removed place to continue to remove the precipitated sludge in a circulating mode.

Description

technical field [0001] The invention relates to sewage treatment equipment and the technical field, in particular to a sedimentation sludge cleaning device for sewage treatment. Background technique [0002] In sewage treatment, sedimentation is one of the most basic methods in sewage treatment. It is a process that uses the settleability of suspended particles in water to sink under the action of gravity field to achieve solid-liquid separation. This process It is simple and easy to implement, widely used, and the treatment cost is low, and it can be a certain process in the whole sewage treatment process. [0003] In the above-mentioned sewage treatment process, the sedimentation sludge treatment is a problem that must be considered. With the continuous innovation of sewage sedimentation treatment technology, there are also various sedimentation tanks. Regardless of the structure of the sedimentation tank, after the separation of water and sediment is achieved , it is nec...
