AI Technical Summary
Traditional sludge scrapers have fixed scraper blades that cannot be adjusted flexibly, resulting in high operating resistance when the sludge thickness is high, which reduces service life and efficiency.
The system uses a combination of a servo motor-driven threaded rod and a U-shaped cross plate, with the height of the scraper blade adjusted via a threaded connection. Sloping scraper blades and spring-connected sliding plates are installed on both sides of the scraper blade to improve its flexibility and stability.
Adjusting the height of the scraper blades reduces operating resistance, thereby improving the service life and efficiency of the scraper and ensuring continuous and efficient sludge removal.
