Chain scraper system for collecting bottom sediment and floating substances
Chain scraper system for collecting bottom sediment and floating substances for a rectangular primary sedimentation tank and secondary sedimentation tank
Scraper description
Chain scraper system is suitable for skimming, dross and scraping sand in rectangular tanks such as sedimentation tanks, grit tanks, grease traps and other rectangular tanks in refineries, water plants or sewage treatment plants. This equipment should be used with auxiliary settings such as oil collection pipes and sludge discharge valves to separate the oil slick residue on the water surface and the sediment at the bottom of the pool to complete the initial purification treatment.
The non-metallic chain scraper is equipped with two parallel closed traction chains. It is equipped with a number of scrapers, and under the traction of the driving device, the chain and scraper run along the guide wheels and guide rails set up and down the sedimentation tank to form a quadrilateral track. Using the scraper to circulate slowly up and down, the oil residue floating on the liquid surface can be scraped from the inlet end to the inlet end of the oil collection pipe and discharged, and the sediment settled at the bottom of the pool can be scraped from the inlet end to the sludge collection tank at the outlet end and discharged through the sludge discharge valve, so as to complete the purpose of the first mechanical purification of sewage.
Features of chain scraper:
1) The number of scraping plates is large, and the ability to scrape mud is strong; The scraper moves slowly, has little disturbance to sewage, and is conducive to sedimentation.
2) The scraper makes continuous linear motion in him, does not have to commutate back and forth, and therefore does not need a stroke switch. The drive unit is located on a platform at the top of the pool, which is easy to distribute and maintain.
3) No additional mechanism is required, and it can double as a skimmer at the same time.
4) There are no heavy structural components and supports in the system, and the energy consumption of the system is low.
