Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically a device for intercepting floating sludge. Background Technology

[0002] Floating sludge discharged from sewage treatment plants is one of the main causes of severe river pollution. Normal floating sludge discharge is about 5%. Floating sludge is a solid or fluid substance. Its solid components mainly include organic debris, bacterial cells, inorganic particles, colloids, etc. It is a mixture mainly composed of organic components, mostly black in color, and will deteriorate water quality when it appears over a large area.

[0003] When the mixture of sewage and floating sludge is discharged into the sewage tank of a sewage treatment plant, the sewage in the sewage tank needs to be pumped out first, and then the floating sludge needs to be dried and sent to a waste-to-energy plant for incineration. However, the existing sewage tanks lack devices to intercept floating sludge when separating sewage, which makes it easy for floating sludge to mix into the sewage and enter the sewage treatment plant. This not only easily clogs the sewage pipes and affects the treatment effect of the sewage treatment plant, but also poses a risk of secondary pollution to the river when the treated water is discharged into the river. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a device for intercepting floating sludge. This device can intercept floating sludge in sewage tanks, preventing it from entering sewage pipes and thus avoiding sludge blockage. This ensures the treatment effect of the sewage treatment plant and also prevents the treated water from being discharged into rivers, thus avoiding the risk of secondary pollution.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for intercepting floating sludge includes a sewage tank and a sewage pipe connecting the sewage tank and a sewage treatment plant. The device further includes an interception plate, a filter plate fixed to the bottom of the interception plate, and a connecting cover mounted on the filter plate for connecting the interior of the connecting cover to a telescopic pipe used in the sewage pipe. The filter holes on the filter plate are positioned facing the interior of the connecting cover.

[0007] Furthermore, symmetrical slide rails are arranged in the sewage tank, and sliders are slidably connected to the slide rails. The two sliders are connected by the interception plate.

[0008] Furthermore, the interceptor plate is a foam board with a thickness of not less than 5cm, and the connecting cover is connected to the connecting cover via a connecting frame.

[0009] Furthermore, multiple scrapers are inclinedly arranged inside the sewage tank, and the two ends of the scrapers are respectively fixedly connected to the two inner side walls of the sewage tank. During the up-and-down sliding of the interceptor plate, the scrapers scrape up and down along the front side of the filter plate.

[0010] Furthermore, the front side of the interceptor plate is flush with the front side of the filter plate.

[0011] The beneficial effects of this utility model are:

[0012] In practical applications, the interceptor plate intercepts the floating sludge on the upper layer of sewage in the sewage tank. The sewage passes through the lower filter plate into the connecting cover and then is discharged into the sewage pipe through the telescopic pipe. This utility model can intercept the floating sludge in the sewage tank, prevent the floating sludge from entering the sewage pipe, avoid the situation of floating sludge clogging the sewage pipe, ensure the treatment effect of the sewage treatment plant, and also avoid the risk of secondary pollution to the river caused by the treated water being discharged into the river.

[0015] like Figure 1 As shown, a device for intercepting floating sludge includes a sewage tank 1, a sewage pipe 2 connecting the sewage tank 1 and a sewage treatment plant, characterized in that: it further includes an interception plate 3, a filter plate 4 fixed to the bottom of the interception plate 3, a connecting cover 5 covering the filter plate 4, and a telescopic pipe 6 used to connect the inside of the connecting cover 5 and the sewage pipe 2, wherein the filter holes on the filter plate 4 are arranged facing the inside of the connecting cover 5.

[0016] In use, the interceptor plate 3 intercepts the floating sludge on the upper layer of sewage in the sewage tank 1. The sewage enters the connecting cover 5 through the lower filter plate 4, and then is discharged into the sewage pipe 2 through the telescopic pipe 6. This utility model can intercept the floating sludge in the sewage tank 1, prevent the floating sludge from entering the sewage pipe 2, avoid the situation of floating sludge clogging the sewage pipe 2, ensure the treatment effect of the sewage treatment plant, and also avoid the risk of secondary pollution to the river caused by the treated water being discharged into the river.

[0017] like Figure 1 As shown, slide rails 7 are symmetrically arranged in the sewage tank 1, and sliders are slidably connected to the slide rails 7. The two sliders are connected by the interceptor plate 3. In this embodiment, when the sewage treatment volume is large or small, the height of the interceptor plate 3 can be adjusted by sliding the sliders up and down along the slide rails 7, which makes it more applicable.

[0018] like Figure 1 As shown, the interceptor plate 3 is a foam board with a thickness of not less than 5cm, and the connecting cover 5 is connected to the connecting cover 5 through a connecting frame; in this embodiment, when the thickness of the foam board is not less than 5cm, it can effectively intercept floating sludge on the water surface and near the water surface.

[0019] like Figure 1 As shown, multiple scraper blades 8 are inclinedly arranged inside the sewage tank 1. The two ends of the scraper blades 8 are respectively fixedly connected to the two inner side walls of the sewage tank 1. During the up-and-down sliding of the interceptor plate 3, the scraper blades 8 scrape up and down along the front side of the filter plate 4. In this embodiment, during the up-and-down sliding of the interceptor plate 3, the scraper blades 8 scrape up and down along the front side of the filter plate 4, which can effectively prevent the floating sludge suspended in the sewage from clogging the plate holes of the filter plate 4.

[0020] like Figure 1 As shown, the front side of the interceptor plate 3 is flush with the front side of the filter plate 4; in this embodiment, the interceptor plate 3 can effectively avoid the scraper 8 when the front side of the interceptor plate 3 is flush with the front side of the filter plate 4.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by this utility model.
