Sludge Scraper Structure and working principle:
The equipment adopts peripheral transmission. The sewage flows in from the inlet pipe in the center of the tank. After diffusion through the flow-stabilizing cylinder, it flows out evenly to the periphery in a radial shape. The suspended sludge is deposited at the bottom of the tank after sedimentation. The driving device drives the working bridge to rotate along the periphery and drives the scraper arm and scraper plate to rotate.
After scraping the sludge from the periphery of the tank to the central sludge collecting tank, it is discharged out of the tank by the sludge discharge pipe by the static water pressure in the tank, The scum on the water surface is skimmed to the side of the pool through the skimming device, and then scraped into the slag bucket by the slag scraper and discharged out of the pool; The supernatant overflows into the outlet tank through the triangular outlet weir plate and is discharged

Sludge Scraper Applications

Sludge discharge in the primary sedimentation tank of the urban sewage treatment plant.

Sludge Scraper Features:
1. The working bridge can be a half bridge or full bridge, and its material can be carbon steel, stainless steel, or aluminum alloy;
2. The driving device adopts shaft mounted helical gear reducer and driving roller direct drive, with a compact structure and high mechanical efficiency
3. The scraper collects mud with the logarithmic spiral track, which has good continuity and high mud collection efficiency;
4. When the bottom slope is 1:10, the resistance during mud scraping can be reduced;
5. Set mechanical and electrical double overload protection to ensure safe and reliable operation
6. The equipment is easy to operate and can directly control the operation of the equipment locally and remotely.
1. It can adapt to a sedimentation tank with a diameter of 10 ~ 50m
2. Half-bridge, half-bridge reinforced, and full-bridge structures can adapt to different sludge volumes
3. Logarithmic spiral mud scraper with high mud collection efficiency
4. Hinged wiper arm to avoid overload damage to the equipment
5. There is a small scraper with loose sludge in the sump
6. Optional materials: carbon steel Epoxy Corrosion protection, stainless steel SS304 or SS316L
7. Optional: central guide cylinder, V-shaped outlet weir plate, slag retaining plate and support of slag skimming device, slag skimming plate, slag discharge cylinder, etc
8. The slag skimming device can be debugged to adapt to the roundness deviation of the sedimentation tank
9. The equipment obtained the certificate of the scientific and technological achievement promotion project of the Ministry of construction in 2002.
