1results about How to "Exit smoothly" patented technology

The utility model relates to a boiler anti-abrasion technical field, concretely for a kind of for circulating fluidized bed boiler anti-abrasion structure, including sealing cover combination part, for the opening of optional shading or exposure hearth top;Abrasion-proof part, present with the half-enclosing structure of lower end opening, the top of abrasion-proof part is fixedly arranged with locking block, sealing cover combination part is opened with the locking port suitable for locking block to go in and out;Locking part, between sealing cover combination part and abrasion-proof part, and locking block and sealing cover combination part can be selectively fixed opposite. The utility model covers hearth top area by abrasion-proof part with its half-enclosing structure, resists the impact force and vibration force generated by material particle, when abrasion-proof part needs to be replaced due to long-term abrasion, sealing cover combination part can be removed first, then the fixed state of locking block and sealing cover combination part is released by adjusting locking part, so that locking block can be smoothly exited from locking port, to realize the quick disassembly and replacement of abrasion-proof part.
