Description

Technical Field

[0001] This utility model relates to the field of water surface scum removal technology, and more specifically, to a vacuum water surface scum removal device. Background Technology

[0002] Scum refers to solid particles suspended in a liquid. These particles float on the surface of the liquid due to their density being less than that of the liquid or due to surface tension. In the biological treatment system of a wastewater treatment plant, foam is an early sign of scum formation. When foam appears in the water due to various factors, over time, the sludge and other solid components in the foam gradually accumulate and settle, eventually forming scum on the water surface. When treating wastewater, it is necessary to clean the scum from the water surface. However, currently, most scum is cleaned by workers using handheld nets, which is inconvenient and has low removal efficiency. Therefore, we propose a vacuum-type water surface scum removal device.

[0021] It should be noted that this utility model is a vacuum-type water surface scum removal device. In use, first, the floating box 1 is placed in the water surface. Moving the floating box 1 changes the position of the scum removal device. Activating the second electric push rod 21 moves the collar seat 22 and the scum suction hood 19 downwards, causing the bottom end of the scum suction hood 19 to extend above the water surface. Then, the vacuum pump 11 is activated to extract the air from the separation chamber 3. The negative pressure suction in the separation chamber 3 causes the scum suction steel pipe 17, scum suction hose 18, and scum suction hood 19 to generate suction. The suction of the scum suction hood 19 draws the scum from the water surface into the separation chamber 3. The lower mesh plate 6 and the upper mesh plate 7 trap the scum. Gas is discharged from the output end of the vacuum pump 11, and water in the scum passes through the lower mesh. The perforated plate 6 falls into the inner cavity of the separation chamber 3 and is collected. Then, the first electric push rod 8 is activated at a timer to move the three baffles 9. At this time, the two baffles 9 on both sides of the inner cavity of the separation chamber 3 move and push the scum filtered down from the lower perforated plate 6 out of a movable slot 5, so that the scum falls into the scum collection box 15 in the inner cavity of a collection chamber 4 and is collected. At the same time, two of the baffles 9 are located in the inner cavities of the two movable slots 5, so that the inner cavity of the separation chamber 3 is sealed again. The lower perforated plate 6 and the upper perforated plate 7 in the inner cavity of the separation chamber 3 continue to intercept the scum. Finally, the scum collection box 15 can be pulled out by holding the handle 16 to clean the collected scum. At the same time, the switch valve 24 is opened to discharge the water collected in the inner cavity of the separation chamber 3 from the drain pipe 25.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
