Sewage treatment plant Chain-plate mud scraper Manufacturer Sedimentation tank Non-metallic chain sludge scraper
1. The chain-plate mud scraper is applicable to the skimming, scum and sand scraping of rectangular tanks such as sedimentation tanks, grit tanks, oil separators in oil refineries, water plants or sewage treatment plants.
2. The chain-plate mud scraper should be used in conjunction with
auxiliary devices such as oil collecting pipe and mud drain valve
to separate the oil slick on the water surface and the mud and sand
at the bottom of the pool and complete the initial purification
treatment.
3. Before entering the sedimentation tank, the sewage must be
filtered to prevent large floating objects from entering.
4. Driven by two parallel chains, the scraper mud scraper moves in
a continuous straight line in the pool. The operation speed is
slow, and the disturbance to sewage is small, which is conducive to
the sediment deposition and the improvement of mud scraping
ability. The circular operation of two parallel closed chains makes
the running direction of the upper and lower chains change
naturally, without the need to control the reverse direction,
simplifying the control procedure and saving the cost. The drive
device is installed on the platform at the top of the pool,
facilitating the repair and maintenance of equipment and electrical
appliances.
Working Principle
The chain-plate oil scraper is equipped with two parallel closed
traction chains. It is equipped with multiple scrapers. Under the
driving force of the drive device, the chain and scraper circulates
along the guide wheel and guide rail set up on the upper and lower
sides of the sedimentation tank to form a four-sided track. The
scraper can move slowly up and down to scrape the floating oil
residue from the water inlet end to the oil collecting pipe at the
water inlet end and discharge it, The sediment settled at the
bottom of the tank is scraped from the inlet end to the sludge tank
at the outlet end and discharged through the sludge discharge
valve, thus completing the primary mechanical purification of
sewage.
Performance Characteristics
1. The moving speed of the scraper is moderate, which has little
disturbance to the sewage and is conducive to the sedimentation of
suspended solids.
2. The scraper makes continuous rotary motion in the pool, without
reversing, and the drive device is located on the platform of the
pool surface, so power distribution and maintenance are very
simple.
3. It can also be used as a skimmer without additional mechanism.
