Specific embodiment:
Embodiment 1: as shown in Figure 1, a kind of cylinder type cold slag machine blowout prevention slag device, including horizontally disposed feed screw
The feed inlet of structure 1, screw feed mechanism 1 is connect with the lower end of clinker feed pipe 2,2 top of clinker feed pipe and boiler slag removal mouth
Connection, 1 discharge port of screw feed mechanism are located inside lag cooler roller 4, pacify between screw feed mechanism 1 and lag cooler roller 4
Equipped with bearing 3, the clinker that clinker feed pipe 2 is discharged is sent in lag cooler roller 4 by screw feed mechanism 1, screw feeding
The power of mechanism 1 comes from lag cooler roller 4, and often the rotate a circle slag amount of conveying of screw feed mechanism 1 is constant, Bu Huiyin
Boiler slag removal pressure increase and cause conveying capacity to increase, it is ensured that clinker stablize enter lag cooler roller 4, avoid high temperature furnace slag
Or it is burning and the cooling equipment of unburned coal dust damage junior and conveying equipment.
Screw feed mechanism 1 is shaft type feed screw 5, in the lesser Installation of Circulation Fluidized Bed Boiler shaft type of slag granules
Feed screw 5 has the effect of centainly clinker being stopped to be gushed out, prevents clinker from largely influxing in lag cooler roller 4.
Embodiment 2: as shown in Fig. 2, a kind of cylinder type cold slag machine blowout prevention slag device, including horizontally disposed feed screw
The feed inlet of structure 1, screw feed mechanism 1 is connect with clinker feed pipe 2, and 2 top of clinker feed pipe is connected to boiler slag removal mouth, spiral shell
Rotation 1 discharge port of feeding mechanism is located inside lag cooler roller 4, is equipped with bearing between screw feed mechanism 1 and lag cooler roller 4
3, the clinker that clinker feed pipe 2 is discharged is sent in lag cooler roller 4 by screw feed mechanism 1, screw feed mechanism 1 moves
Power come from lag cooler roller 4, screw feed mechanism 1 often rotate a circle conveying slag amount be it is constant, will not be because of boiler slag removal
Pressure increase and cause conveying capacity to increase, it is ensured that clinker stablize enter lag cooler roller 4, avoid high temperature furnace slag or firing
It burns and unburned coal dust damages the cooling equipment of junior and conveying equipment.
Screw feed mechanism 1 be shaftless feed screw 6, the biggish Installation of Circulation Fluidized Bed Boiler of slag granules without
