Reliable Operation Dust Removal Equipment Coal Cleaning Machine For Power Plant

Original coal cleaning machine for power plant Raw coal bunker in thermal

Principle of structure

Original coal cleaning machine is mainly composed of upper fixed support, the lower fixed support, middle rotary storehouse, driving device, rotary support device, supporting boom, shield, built-in flow cross-section of scraper, sealing device, intelligent and other components of the electric control cabinet, motor reducer drive pinion, pinion and rotary support tooth, the big gear and the intermediate fixed rotary storehouse, gear have a shield to protect.When the clogging bunker, and bunker coal feeder attached to the sensor signal of break of break, drive, motor reducer drive pinion drive wheel rotation, rotation, thus promote the middle rotary storehouse of built-in flow cross-section of scraper fixed at the bottom of the upper fixed support and fixed support, in the middle rotary warehouse to warehouse wall and the arch in the process of rotating parts for broken arch, arch stress point break the material, the break its form the basis for loose material, the arch vortex flow of material and generate a downward thrust the storehouse the flow of the material in the flow by the center for whole flow again,Thus, the blockage of particulate matter in tapered silo can be solved fundamentally.

Technical features

1, the original coal bunker to unblock machine has advanced design idea, the built-in flow cross-section of scraper fixed at the bottom of the upper fixed support and fixed support, motor reducer drive pinion, pinion and gear mesh, big gear spins rotary positions among rotate, embedded in the spinning process flow cross-section of scraper cleaning work silo wall broken arch, small motor power, power saving.

2. The original coal bunker clog removal machine is installed in the easy clog section of the cone (within 1.5m-3m above the coal gate mouth), and the arch breaking effect is remarkable.

3, the original coal bunker clearance machine adopts the internal streamline variable section scraper technology, reduce the scraper cutting force, increase the anti-blocking height.

4, can achieve remote local control conversion, can manually control the action, but also can realize the servo timing start and stop plus stop signal instantaneous start and stop.

5. The flow state in the warehouse can be changed to restore the flow state of materials in the warehouse from the central flow to the overall flow.

6. Adopt integral axial labyrinth seal compound groove seal design, no leakage of powder, prevent dust overflow, improve the working environment.

7, reasonable design, simple structure, reliable operation, easy installation, small maintenance, especially suitable for the old power plant bunker technical transformation.

8. Split body design, convenient disassembly and replacement of warehouse and stick valve, overload protection in electrical design and PLC control, once the internal scraper has a large block or other foreign body stuck, electrical signal feedback will make the motor reverse, eliminate the blockage, and restore forward turn after eliminating the blockage.
