Description

Technical Field

[0001] The utility model belongs to the technical field of biogas slurry treatment flotation machines, in particular to a biogas slurry treatment flotation machine. Background Art

[0002] Biogas flotation machines are used to treat biogas slurry (wastewater from farms, slaughterhouses, and other locations containing large amounts of suspended matter and organic matter). They operate by generating tiny bubbles that bind suspended matter to the bubbles, achieving solid-liquid separation. Their core components include a dissolving air device, a releasing device, and a flotation unit. The dissolving air device dissolves air in water to form dissolved air water, which is then rapidly released through the releasing device to form tiny bubbles. The flotation unit then uses these bubbles to lift suspended matter, achieving solid-liquid separation. However, biogas flotation machines have certain drawbacks. For example, when biogas slurry floats into the collection tank, it still contains a significant amount of water. Direct treatment of the biogas slurry can easily result in water waste.

When the scraper 1305 scrapes, clean water will enter the fourth cavity 9, and then the clean water will enter the fifth cavity 10 along the filter port at the bottom end of the first partition plate 2. At the same time, some separated matter smaller than the filter port will also enter the fifth cavity 10.

[0031] Example 5

At this time, the fifth cavity 10 also has biogas slurry and clean water. As the clean water in the fifth cavity 10 increases, the biogas slurry floats up and contacts the filter plate 1401, and is then blocked by the filter plate 1401. At this time, the clean water will be above the biogas slurry, and then the discharge port 17 can be opened to discharge the clean water. At the same time, the filter plate 1401 is blocked and the rotatable limit block 1405 can move.
