Embodiment Construction
[0011] Such as figure 1 , figure 2 , image 3 As shown in Figure 4, the present invention adopts the method of double-layer furnace shell structure, and a layer of thin steel plate or aluminum plate 2 is installed outside the furnace shell 1, and the closed air layer formed increases the thermal resistance, forming a double-layer furnace shell, two layers The bolts 3 of the porcelain tubes or other methods can be used to connect between them, the surface temperature of the furnace is further reduced to reduce heat loss, and a layer of refractory fiber 4 can also be pasted on the inside or outside of the double-layer furnace shell, and the effect is better. Movable cover plates 7, 8 are installed on the bottom 5 and the top 6 of the double-layer furnace shell. When heating and heat preservation, the upper cover 7 and the lower cover 8 are closed, and the double-layer furnace shell forms a closed air layer to reduce heat loss. Open the upper and lower covers 7 and 8 during co...
