AI Technical Summary

Technical Problem

Existing rotary feeders with cellular wheels require complex maintenance procedures, as the entire cellular wheel must be removed to replace damaged sealing lips or knives, leading to increased costs and reduced accessibility for maintenance.

Method used

The design features a housing with removable side parts that form walls of the lock chamber, allowing for easy access and maintenance without the need to remove the cellular wheel. The side parts are operatively releasable from the outside, and the housing is constructed using simple metal sheets to reduce costs and complexity.

Benefits of technology

This design simplifies maintenance by allowing easy removal and replacement of side parts, reducing the need for complex disassembly and reassembly, thereby lowering maintenance costs and improving accessibility for maintenance tasks.
