Specific implementation mode
The utility model is further described below in conjunction with attached drawing and specific embodiment.
It is the structural schematic diagram of the utility model as shown in Figure 1.The roaster includes backpack cover 1, pre- hot-flow flue 2 and burner 3.
Backpack cover 1 is made of backpack cover skirtboard 11 and backpack cover panel 12, and backpack cover 1 is cast with fire resisting centered around 3 circumferential direction of burner
Castable 13,13 outer layer of castable refractory are provided with refractory cotton partition board 14, refractory cotton containing zirconium 15 are wound with outside refractory cotton partition board 14
Until the outer of backpack cover 1, the outer circumferentially cast refractory cement castable 16 of backpack cover 1
Burner 3 uses exterior mixing burner, is set to 1 center of backpack cover and runs through backpack cover.Burner 3 is by cylindric air chamber
4 and gas chamber 5 form, air chamber 4 is sleeved on the outer layer of gas chamber 5, is provided between gas chamber 5 and air chamber 4 around coal gas
The three-level mixing chamber 6 of room 5, three-level mixing chamber 6 are set gradually from small to large according to caliber.3 bottom of burner is additionally provided with for combustion-supporting
Sky, the coal gas mixing chamber 7 of hot wind and coal gas mixing, empty, coal gas mixing chamber 7 are by the refractory casting around the circumferential cast of burner 3
Chamber made of material 13 encloses also has been arranged circumferentially premix stick 17 in 13 lower end of castable refractory.
The pre- hot-flow flue 2 is made of pre- hot-flow flue underdress plate 20 and pre- hot-flow flue upper cover plate 21, can pass through weldering
The mode connect is arranged in the upper end of backpack cover 1, and rounds.The pre- hot-flow flue entered for air is offered on pre- hot-flow flue 2
Entrance 8, preheating tunnel inlet are connected with tunnel inlet straight tube 22, convex surface slip-on welding flange are connected on tunnel inlet straight tube 22.
The offside of preheating tunnel inlet 8 offers hot air outlet 9, and hot air outlet 9 is connected to the sky of burner 3 by hot air duct 10
Gas chamber 4, to be the combustion air after the conveying preheating of burner 3.
