Problems solved by technology
The roof of the traditional fluidized roasting furnace is made of refractory bricks, and the flexibility of the roof is poor, so the structural stability and thermal stability are poor, and bricks are prone to fall off during use, which is poor in safety
The furnace roof made of refractory bricks is prone to air leakage and poor environmental protection. The sulfur dioxide gas exposed from the furnace body will form sulfuric acid and easily corrode the furnace shell.
[0003] In addition, the size of the furnace roof made of refractory bricks is limited, thereby limiting the size of the roasting furnace. Furnace size is limited
In order to build a furnace roof with refractory bricks, it is necessary to process the refractory bricks in order to obtain various special-shaped bricks, but the large number of refractory bricks makes processing difficult, thus increasing the difficulty of building the furnace roof and increasing the cost.
[0004] In addition, the smoke outlet, feed inlet and outlet of traditional fluidized roaster are also made of refractory bricks and heat insulation bricks, so the processing of smoke outlet, feed inlet and outlet is complicated and costly

The invention discloses a fluidized calcining furnace which comprises a furnace body, a furnace top and an air box, wherein the furnace body comprises a feed inlet, a discharge outlet and a smoke outlet; the furnace top is one-piece and arranged at the top part of the furnace body; and the air box comprises an air inlet and an air outlet, and the air box is arranged below the furnace body and communicated with the interior of the furnace body through the air outlet. As the furnace top is one-piece, the fluidized calcining furnace has good softness, high structural stability, high safety performance, good thermal stability and good sealing performance. Furthermore, due to good structural stability and good thermal stability of the furnace top, the size of the furnace top can be increased, thereby being capable of increasing the size and the furnace capacity of the furnace body and improving the calcining quality and the production efficiency.
Description
technical field [0001] The invention relates to a fluidized roasting furnace, in particular to a fluidized roasting furnace with an integrated roof. Background technique [0002] Fluidized roaster is a commonly used pyrometallurgical roasting equipment, which is used to roast mineral materials. The roof of the traditional fluidized roaster is made of refractory bricks. The flexibility of the roof is poor, so the structural stability and thermal stability are poor, and bricks are prone to fall off during use, and the safety is poor. The furnace roof made of refractory bricks is prone to air leakage and poor environmental protection. The sulfur dioxide gas exposed from the furnace body will form sulfuric acid and easily corrode the furnace shell. [0003] In addition, the size of the furnace roof made of refractory bricks is limited, thereby limiting the size of the roasting furnace. The upsizing of the furnace is limited. In order to build the furnace roof with refractory ...
