Description

Technical Field

[0002] A roasting furnace is an industrial equipment used for heat treatment of various materials. It changes the physical or chemical properties of materials by heating them to a certain temperature and keeping them at that temperature for a period of time. Roasting furnaces are widely used in many industries such as metallurgy, chemical industry, building materials, ceramics, etc., and are used to process minerals, catalysts, powder metallurgy materials, ceramic raw materials, etc. Existing roasting furnaces include a furnace body and a heating element. The heating element is assembled inside the furnace body, and the heating element generates heat to heat the object in the furnace body.

[0003] The existing announcement number is CN203798140U, and the name is a combined roasting furnace, which includes a rotating cylinder and an insulating furnace. A material inlet is provided at one end of the rotating cylinder, and a material outlet is provided at the other end. The insulating furnace is mounted outside the rotating cylinder, and also includes a direct burner and an indirect burner. The direct burner is arranged at the discharge end of the roasting furnace, and the indirect burner is arranged on the insulating furnace. A combustion system combining direct combustion and indirect combustion is adopted to improve the roasting temperature control accuracy, improve the thermal efficiency of the roasting system, improve the roasting quality, and reduce production costs. There are multiple indirect burners, which are evenly arranged on the side of the insulating furnace. The direct burner is arranged at the discharge end of the roasting furnace. The high-temperature flue gas generated by the direct burner is countercurrent to the material flow direction, and is discharged from the feed end of the roasting furnace after heat exchange with the material. The air-fuel ratio of the indirect burner is 30~40, and the burner adjustment ratio is 5~10. The direct burner is arranged at the discharge end of the roasting furnace. The high-temperature flue gas generated by the combustion enters the rotary cylinder and directly contacts the material for heat supply. At the same time, the heat load ratio of indirect and direct combustion can be adjusted. It can be applied to the roasting of various materials. The heat load ratio of indirect combustion and direct combustion can be adjusted according to different process requirements and can be applied to the roasting of various materials.

[0004] However, the above-mentioned roasting furnace is equipped with both a direct heating burner and an indirect heating burner integrated inside the furnace body. The direct heating burner and the indirect heating burner can be heated at the same time or used individually. Such integrated burners are fixed in the furnace body and are easily affected by heat from each other during combustion, resulting in a reduction in the combustion life of the direct heating burner and the indirect heating burner regardless of whether they are used or not. At the same time, the integrated direct heating burner and the indirect heating burner have a single combustion mode, and the adjustable selectivity of the combustion and heating mode is reduced. It is costly to set up a plurality of roasting furnaces with different combustion modes, which is not conducive to large-scale processing and rotation. Summary of the invention
