Selection of Bridge Scraper

Overview of scraper:

In sewage treatment plants, the scraper is a very important large-scale engineering product, mainly used in circular sedimentation tanks of sewage treatment plants. The scraper can discharge the sludge settled at the bottom of the tank to the outside of the tank. The scraper is divided into peripheral transmission scraper, bridge scraper, traveling scraper, and pump/Siphon scraper, etc. The Feili Environmental Protection Mud Scraper has a large transmission torque, low energy consumption, and is equipped with a protective mechanism. When the resistance is too high, it will automatically alarm and stop, ensuring safe and stable operation, good quality, and high cost-effectiveness. The selection of a scraper needs to be considered from two aspects: one is the types of scrapers, and the other is the material selection of the scraper.

Selection of Bridge Scraper

Selection of types of mud scraper:

Choosing a suitable scraper can effectively solve the major problem of urban sewage. When choosing a scraper, factors such as equipment material, product performance parameters, and surrounding environment need to be considered. For example, in which tank is the scraper used? The sludge concentration and sediment content in the primary sedimentation tank are relatively high, so the speed of the scraper is relatively faster. The sludge in the secondary sedimentation tank is relatively less than that in the primary sedimentation tank, and the speed is slightly slower. Depending on the size of the sedimentation tank, the diameter is generally larger than18mFor the sedimentation tank, choose a center driven scraper, below18mChoose a peripheral transmission scraper.

Material selection for scraper:

The materials used for Feili Environmental Protection Mud Scraper are of excellent quality, wear-resistant and high-temperature resistant. The selection of materials is first considered based on the user's needs. The equipment adopts a new type of straightening support structure, which improves the load-bearing condition of the mud scraper. It is equipped with a torque protection device, which has good safety performance. The driving device has been optimized for long service life and high efficiency. The scraper curve adopts logarithmic spiral type, which has good scraping effect.
