The invention provides an external heating type rotary furnace for semi coke production. The external heating type rotary furnace comprises: an outer shell; a maintenance plate; six position limitingplates, wherein each two position limiting plates form a group and are fixed between the outer shell and the maintenance plate; a storage chamber arranged between the outer shell and the maintenance plate, wherein two of the position limiting plates, the maintenance plate and the outer shell enclose to form the storage chamber; a dry distillation chamber; a cooling structure; three driving structures used for conveying a material and respectively and linearly fixed in an equidifferent manner inside the storage chamber, the dry distillation chamber and the cooling structure, wherein the drivingstructure comprise a motor, a driving gear, a transmission gear, a conveying sleeve, a position limiting stopping ring, multiple projections and a baffle; three flow guiding sleeves; a dry distillation structure; a waste gas utilization structure; a material discharge chamber; and a wiring box. According to the present invention, the external heating type rotary furnace has advantages of convenient semi coke transportation, high heat exchange efficiency and good dry distillation quality.
Description
technical field [0001] The invention relates to the technical field of semi-coke production and processing equipment, in particular to an externally heated rotary furnace for semi-coke production. Background technique [0002] Semi-coke is fired from the high-quality Jurassic clean coal abundant in Shenfu Coalfield. As a new type of carbon material, it has high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, The characteristics of low sulfur and low phosphorus are widely used in the production of calcium carbide, ferroalloy, ferrosilicon, silicon carbide and other products to gradually replace metallurgical coke. Thereby increasing the carbonization rate of semi-coke. [0003] However, the traditional externally heated rotary furnace for semi-coke production is easy to cause semi-coke damage during the process of transporting semi-coke, and the transportation convenience is poor, and the heat exchange efficiency is not good. ...
