AI Technical Summary
Technical Problem
Existing stacked screw filter presses are prone to clogging the feed inlet when conveying slurry with high viscosity and caking. Furthermore, after prolonged use, the crushing rollers become covered with mud, which weakens the crushing effect.
Method used
A stacked screw filter press for sludge dewatering, including a feeding crushing mechanism and a cleaning mechanism, was designed. Through the linkage of scrapers and shovels, and using a drive motor and linkage gear system, the crushing rollers are automatically cleaned to avoid mud adhesion.
Benefits of technology
It effectively prevents mud from adhering to the surface of the crushing roller, maintains the crushing effect, avoids clogging the feed inlet, and improves the continuous operation capability of the equipment.

Abstract
This utility model relates to the technical field of stacked screw filter presses and discloses a stacked screw filter press for sludge dewatering. It includes a stacked screw filter press body and a feed inlet located at the top of the body. A feeding crushing mechanism is provided at the top of the body. In this stacked screw filter press for sludge dewatering, through the feeding crushing mechanism and cleaning mechanism, when the feeding crushing mechanism is working, the lifting rod can be controlled to move upwards via a linkage. The lifting rod can abut against the bottom of the scraper, pushing the scraper to swing upwards at a position hinged to the feed frame, thereby causing the scraper to abut against the crushing roller. As the crushing roller rotates continuously, the scraper can scrape off the mud adhering to the crushing roller, preventing the crushing roller from becoming smooth due to prolonged use and thus failing to perform an effective crushing function.
