Abstract

The invention provides a multi-hearth roaster and a building method thereof. The multi-hearth roaster comprises a central discharge hole and peripheral discharge holes. Stainless steel bars penetrate through combination bricks at the peripheral discharge holes. The multi-hearth roaster and the building method thereof prevent falling of bricks from the discharge holes.

Description

technical field [0001] The present application relates to a multi-layer roasting furnace and its building method, more specifically, the present application relates to a multi-layer roasting furnace capable of preventing bricks from dropping at the feeding port and its building method. Background technique [0002] Self-suspended multi-layer roasting furnace is roasting V 2 o 3 Important thermal equipment for raw materials, there are eleven layers of hearth in the furnace. The upper surface of the hearth is a horizontal plane, and the lower surface is a conical surface with a taper of 5°38'. There is a rotatable shaft in the center, and the rake arm rake is installed on the hollow shaft of each hearth. When the rake arm rotates with the hollow shaft, the charge is raked from the upper hearth layer by layer. The gap between the rake arm and the hearth is controlled at 20mm, and the gap between the rake arm and the furnace wall is 20-25mm. [0003] Due to the complex chemi...
