Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. In Fig. 1, Fig. 2 and Fig. 3, the continuous ore roasting furnace has a vertical and horizontal structure, and the main materials are commonly used materials such as refractory, heat preservation, and steel structures. The two sides of the roasting furnace can be evenly or unevenly distributed. The combustion spout 6 of the vault 1 above it leads to the hearth of the roasting furnace, and the crawler belt 3 running in the raw material conveyor 12 in the furnace is placed on ores, such as vanadium pentoxide, magnesium ore dolomite, manganese ore and other ores. Run slowly to the right, the left end of the roasting furnace is the flue 7, and there are several oxygen injection holes 4 on the top of the roasting furnace, and the inclined angle α can be any angle between 15° and 60°, such as: 15°, 18° , 20°25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°. The direction...

Abstract

The invention discloses an ore continuous bake furnace, which can solve the defects of hearth-furnace and revolution furnace that short bake time and lower weight when continuously baking colorful metallic ore, as vanadic anhydride. Wherein, the hearth comprises a material feeder 12; two sides of bake furnace are distributed with burning furnace 2; the middle of bake furnace is mounted with a material mixer 5; the arc top of furnace 1 has an incline oxygen ejector 4. The invention can realize bath and automatic production, with high baking efficiency, while it can bake vanadic anhydride and other metallic ores.

Description

1. Technical field [0001] The invention relates to a continuous roasting furnace for ore, in particular to a continuous roasting furnace for metal ores such as vanadium pentoxide. 2. Background technology [0002] At present, the known continuous roasting furnaces of non-ferrous metal ores such as vanadium pentoxide have not been reported yet. The furnaces for actually roasting vanadium ores include open hearth furnaces, rotary kilns, multi-hearth furnaces, fluidized fluidized furnaces, etc., and the roasting residence time is too short 2-3 hours, the residence time required for continuous roasting cannot be reached, and the output is low, so it can only be suitable for small factories. The State Intellectual Property Office announced an adsorbent tubular continuous roaster on July 27, 2005. The patent number is 200420060360, and the announcement number is 2712456. Its structure is that the adsorbent tubular continuous roaster includes a burner, a combustion furnace, Roasti...
