Background technology
Before the utility model was made, traditional rotary kiln mainly was made up of feed bin, feed appliance, main drive, rotating cylinder, kiln body kiln tail output section.Material drives the rotating cylinder rotation by feed bin and feed appliance input rotating cylinder by main drive, in kiln body fuel combustion process with rotating cylinder in material calcining, be delivered to kiln tail discharging cooling.It drives the interlude that main drive that rotating cylinder rotates is arranged on revolving drum, and the kiln body separately be arranged on rotating cylinder about portion.This rotary kiln adopts only low temperature resistant material because of its revolving body, and flexural deformation can appear in cylindrical shell when ignition temperature is higher, so its main drive can only be arranged on the interlude of cylindrical shell.When material moves to interlude in cylindrical shell, because its interlude temperature is lower, calcining heat is inhomogeneous in the cylindrical shell, badly influence the end product quality of material, the scope of application is narrow, and the low-grade product that can only be used to burn is as molecular sieve etc., can not calcine expensive goods, as ardealite behind the power plant desulfurization etc.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of revolving body can flexural deformation, simultaneously in the cylindrical shell power plant desulfurization of calcining heat uniformity with clearance-type automatic control rotary kiln.
The purpose of this utility model is achieved in that a kind of power plant desulfurization clearance-type automatic control rotary kiln, it is characterized in that described rotary kiln comprises feeding end supporting leg, discharge end rack leg, kiln body steel structure I, kiln body steel structure II, calcining cylindrical shell, Elema, feed system, kiln hood carrying roller and kiln afterbody carrying roller
Described kiln body steel structure I is set up on feeding end supporting leg and the discharge end rack leg,
Described kiln body steel structure II upwards is installed on the kiln body steel structure I, the calcining cylindrical shell is horizontally installed on the kiln body steel structure II, stretch out outside the kiln body steel structure II at the two ends of calcining cylindrical shell, wherein an end is the kiln hood end, the other end is the kiln tail end, and described Elema has some, is divided into two rows up and down, evenly be inserted in the calcining cylindrical shell
Described feed system is installed on the front side of calcining cylindrical shell kiln hood end, is connected with the calcining cylinder lumen,
Described kiln hood carrying roller and kiln afterbody carrying roller are supported on the kiln hood end and the kiln afterbody of calcining cylindrical shell respectively, and described retaining wheel is arranged at kiln hood carrying roller side.
Compare with existing rotary kiln, because main drive of the present utility model is arranged on the kiln hood end of calcining cylindrical shell, calcining cylindrical shell device is in kiln body steel structure II, make calcining cylindrical shell calcining heat even, the end product quality height of calcining materials, the scope of application is wider, removes to be used to calcine low-grade product, outside molecular sieve, all right calcined phosphogypsum etc.
