Sludge scraper

The chain plate type scraper and slag skimmer is widely used in sewage treatment plants to continuously discharge mud at the bottom of horizontal flow sedimentation tanks, sand settling tanks, and oil separators (basically similar to the gantry type scraper and suction machine), and can continuously remove oil or scum on the water surface, especially suitable for sedimentation tanks with more sediment. For projects with a lot of particulate matter in the water and urgent need for good water quality, fillers for auxiliary sedimentation can be installed in the middle of the chain plate.

1. The scraper load is large and the oil is scraped thoroughly.

2. It can be linked with the oil collecting pipe and the mud discharge valve.

3. The scraper moves at a moderate speed and has little disturbance to the water.

4. The tension can be adjusted, and the transmission is stable and reliable.

5. The double chain traction scraper runs smoothly.

HGXF type gantry type scraper and suction machine consists of a crane, scraper rake, suction pump, guide tube, guide rail, drive device and control cabinet.

Gantry type scraper and suction machine

According to whether the sludge collecting tank is set at the same end of the sedimentation tank or at both ends, the working process of the scraper and suction machine is as follows:

1. When the scraper rake descends, the scraper and suction machine travels from the water outlet end of the pool to the mud and slag trough end, and transports the sludge and floating sludge to the end point (water inlet end). The suction pump placed in the guide tube at the bottom of the scraper and suction sludge sucks the precipitated sludge into the sludge collecting tank.

2. Used in the horizontal flow sedimentation tank of the sewage treatment plant, the sludge settled at the bottom of the pool is scraped and sucked into the sludge collecting tank, and the floating slag on the pool surface is skimmed to the slag collecting tank.
