Abstract

The utility model discloses a circulating washer breaking device for the solid material breaking, particularly suitable for the bruising of boiler fuel materials (such as a gangue, middle coal and the like), comprising a 1<#> belt transmission device (2), a steel removing device (4), a breaking device (5) under a material exhaustion end of the 1<#> belt transmission device (2), an equal thickness sieve (6), a 2<#> belt transmission device (7) under the equal thickness sieve (6) and a lifting device (3) equipped on the material exhaustion end of the equal thickness sieve (6) and the like. Fuels are sieved by a bruising sieve, big particle fuels are sent to the 1<#> belt transmission device (2) through the lifting device (3) then performs bruising and forms cycling, thereby the utility model can has the features of good bruising effect, avoiding big particle fuels from going inlet the boiler, then the fuel is burnt more fully, thereby ensuring the stable operation of the boiler.

Description

The cycle crushing device
One, affiliated technical field
The utility model is the cycle crushing device that a kind of solid material carries out broken usefulness, and is specifically a kind of when being mainly used in boiler operatiopn, its fuel coal (as gangue, middle coal etc.) carried out the cycle crushing device of broken usefulness.
Two, background technology
At present, the most circulating fluidized bed boilers that adopt of China steam power plant, such boiler requires very strict to the granular size of fuel, gangue, middle coal are in burning, if the bad fuel particle of crushing effect is too big, in the combustion process fuel sulfuration bad, it is insufficient to burn, increased energy loss greatly, when serious even can cause boiler coke.In addition because burning is insufficient, the coal ash particle after the burning increases, wearing and tearing have been strengthened with boiler plants such as burner hearth inside, cyclone dust collector, economizer, air preheaters, increased the load of pressure fan, air-introduced machine, also influence dust removing effects, thereby influenced the safety and economic operation of boiler.
Three, summary of the invention
The purpose of this utility model provides a kind of broken cycle crushing device that can circulate.Its fragmentation that the macro particles fuel after the fragmentation can be circulated enters boiler to avoid macro particles fuel, thereby guarantees the normal operation of boiler.
The technical scheme that the utility model is taked is: former breaker is improved, uniform thickness sieve is arranged on disintegrating machine after, set up a lifting device.Be that the utility model is by 1 #Belt conveyor, tramp iron separator, disintegrating machine, uniform thickness sieve, elevator, 2 #Compositions such as belt conveyor.Tramp iron separator is located at 1 #The appropriate position of belt conveyor, disintegrating machine is located at 1 #The delivery end downside of belt conveyor, the uniform thickness sieve is located at the downside of disintegrating machine, 2 #Belt conveyor is located at the downside of uniform thickness sieve, and the lower end of elevator is located at the material that removes of uniform thickness sieve and holds, and the upper end of elevator is located at 1 #The delivery end of belt conveyor.
Fall into the uniform thickness sieve after disintegrating machine is with fuel (as gangue, middle coal etc.) fragmentation, the uniform thickness sieve is discharged into 2 with the satisfactory fuel of the particle that sifts out #Belt conveyor is by 2 #Belt conveyor is delivered to boiler for use, and the macro particles fuel that uniform thickness sifts out unloads to elevator except that the material end from it, is carried to 1 by elevator #The delivery end of belt conveyor enters disintegrating machine again and carries out fragmentation, so forms circulation.
Because the utility model improves former breaker, to wait sieve to be arranged on the disintegrating machine downside, and set up elevator, it is broken to have formed circulation, therefore it is good to the utlity model has crushing effect, avoid macro particles fuel to enter boiler, made burning more abundant, and guaranteed the characteristics such as stable of boiler.
Four, description of drawings
Accompanying drawing is the utility model schematic diagram.
Five, specific implementation method
As shown in the figure, the utility model is by 1 #Belt conveyor 2, tramp iron separator 4, disintegrating machine 5, uniform thickness sieve 6, elevator 3,2 #Belt conveyor 7 compositions such as grade.Elevator 3 is a bucket elevator.Tramp iron separator 4 is installed in 1 #The upside of belt conveyor 2 delivery ends, disintegrating machine 5 is located at 1 #The downside of belt conveyor 2 delivery ends, uniform thickness sieve 6 is located at the downside of disintegrating machine 5,2 #Belt conveyor 7 is arranged on the downside of uniform thickness sieve 6.The charging aperture of elevator 3 lower ends is arranged on removing of uniform thickness sieve 6 and expects the end place, and the discharge port of elevator 3 upper ends is arranged on 1 #The delivery end place of belt conveyor 2.
The feeder 1 of Bunker unloads fuel (as gangue, middle coal) to 1 #Belt conveyor 2 is discharged into disintegrating machine 5 after tramp iron separator 4 deironing, be discharged into uniform thickness sieve 6 after fragmentation, and the fuel after 6 pairs of fragmentations of uniform thickness sieve carries out vibration screening, and the satisfactory fuel of particle unloads to 2 #Belt conveyor 7 is by 2 #Belt conveyor 7 is delivered to boiler for using.Oarse-grained fuel then unloads to elevator 3 from the material end that removes of uniform thickness sieve 6, and elevator 3 is with its lifting and unload to 1 #Belt conveyor 2 carries out second-time breakage again, and so circulation has guaranteed crushing effect.This shows that it is good to the utlity model has crushing effect, avoided macro particles fuel to deliver to boiler and used, make fuel combustion more abundant, thereby guaranteed characteristics such as boiler operatiopn is steady.
