Description
Technical field
The utility model relates to a kind of breaker, is specifically related to a kind of bucket conical section and arranges continuous crushing device, destroy the coal cinder constantly hardened, thus reach the continuous coal breakage of coal bunker, the breaker of the coal cinder that hardens in the coal bunker of feeder continuous uniform coal supply.
Background technology
In power plant combustion system, coal bunker is one of important equipment, prevent raw coal in coal bunker to harden blocking, ensure the key run continuously of boiler, when power plant come that coal particle is little, ash content and washiness time, above the raw coal of the conical section of coal bunker is subject to, the weight of raw coal hardens into the coal cinder of various shape, the result caused has two kinds, first coal cinder diameter is excessive, causes coal hopper coal blockage, thus causes feeder to break coal; It two is that coal cinder can drop into feeder, but because diameter is greater than coal chute of coal feeder bore, is blocked, cause belt creep by feeder baffle plate, thus causes coal pulverizer to break coal.
Current solution has following several:
1. nitrogen big gun (air bubble), comparatively effective to loose granular chute blockage, but for the above-mentioned situation that hardens, without any effect, the coal cinder that hardens only can be allowed more closely knit.
2. bulkhead scrapper conveyor, only useful to raw coal " bridging " phenomenon, for the major diameter coal cinder hardened, also without any actual effect.
3. manually knock coal bunker, coal disclosed by drill rod, and this kind of block clearing mode labour intensity is large, and leakage pollution is comparatively obvious, limited efficiency and easily damage equipment.
Utility model content
