Blockage and coal arching are frequent failures plaguing thermal power plant raw coal conveying systems. The rotary silo blockage cleaning machine is mainstream anti-blocking equipment specially developed for silos and coal chutes. Different from static silo wall flow aid equipment, this rotary device relies on rotating scraping components to achieve active dredging. When matched with electro-hydraulic slide gate valve and arch breaker machine, it forms a complete solution to eliminate material adhesion and silo bridging.

1. Rotary Scraper Structure Achieves Dead-angle-free Cleaning

The core of the rotary silo blockage cleaning machine is the rotary vortex scraper assembly. During operation, the scraping mechanism rotates continuously along the silo inner wall. It can scrape off sticky coal and material deposits attached to the silo wall, avoiding the formation of fixed dead coal zones. This design solves the problem of incomplete cleaning existing in many traditional silo blockage clearing equipment.

2. Dual Operating Modes: Automatic Timing and Manual Control

The rotary silo blockage cleaning machine supports two operation modes. It can run automatically according to preset cycles to prevent coal accumulation before blockage forms. When serious coal arches appear, operators can switch to manual mode to start forced dredging. Flexible operation adapts to unstable coal humidity and variable material flow in actual production.

3. Optimized Structure Solves Traditional Equipment Defects

Many early silo cleaning machines suffer coal leakage, severe scraper wear and insufficient transmission torque. The upgraded rotary silo blockage cleaning machine adopts optimized sealing structure and wear-resistant scrapers. It effectively avoids coal leakage, strengthens the connection between scrapers and the main shaft, and improves transmission torque to cope with compacted bulk raw coal.

4. Intelligent Frequency Conversion Control for Energy-saving Operation

Equipped with frequency conversion control system, the rotary silo blockage cleaning machine can adjust rotation speed according to on-site working conditions. Under light load conditions, low-speed operation reduces wear and power consumption. In severe blockage conditions, high torque output ensures reliable arch breaking. It can realize linkage control with coal feeders and electro-hydraulic slide gate valve.

5. Wide Adaptability for Multiple Silo Types

The rotary silo blockage cleaning machine can be installed on rectangular tapered bunkers, conical bunkers and hyperbolic raw coal bunkers. It is widely used in thermal power, metallurgy and mining industries to handle raw coal, mineral powder and other viscous bulk materials. It can be installed at the lower silo section or coal drop chute to cooperate with silo wall flow aid equipment for comprehensive anti-blocking.
