Description

Technical Field

[0001] The utility model relates to the field of mud scrapers, in particular to a mud scraper capable of quickly discharging mud. Background Art

[0002] Sedimentation tanks are common equipment in sewage treatment plants. Suspended matter in sewage settles in the sedimentation tank and eventually forms sludge. The sludge needs to be pushed to the sludge outlet at the center of the sedimentation tank by a sludge scraper. The bottom of the sedimentation tank in the prior art is funnel-shaped, and its bottom surface is inclined toward the sludge outlet. During the rotation of the sludge scraper, the scraper blade clings to the bottom of the sedimentation tank and pushes the sludge around the sludge outlet. During the movement of the sludge, it gradually slides downward along the inclined bottom surface and then slides to the sludge outlet. The sludge entering the sludge outlet is discharged through a conveying device.

[0003] According to a scraper disclosed in Chinese patent CN202120676459.9, the application was approved, including a scraper body and a mud pushing device arranged on the scraper body. The scraper body is provided with a scraper plate. The mud pushing device includes a spiral shaft. The spiral shaft is arranged close to the scraper plate. The spiral shaft extends along the radial direction of the sedimentation tank. When the scraper is in use, the scraper plate moves along the bottom surface of the sedimentation tank. In this process, the scraper plate gradually pushes the sludge forward. At the same time, the spiral shaft rotates and transports the sludge collected by the scraper plate to the mud discharge port at the center of the sedimentation tank. This type of scraper not only pushes the sludge through the scraper plate, but also quickly pushes the sludge to the sludge discharge port through the spiral shaft, thereby improving the scraping efficiency. When in use, the existing scraper drives the impeller to rotate through the water flow and then drives the spiral shaft to rotate to quickly transport the sludge to the sludge discharge port. However, when the scraper is running, the sludge in the sedimentation tank will float with the water flow and adhere to the impeller, affecting the rotation efficiency of the impeller. At the same time, when the water level in the sedimentation tank is lower than the impeller, it affects the rotation of the impeller.
