Discharge device roller structure

Abstract

The invention relates to a discharge device roller structure which comprises a discharge roller, wherein the discharge roller is composed of a plurality of single roller rows which are arranged along the axial direction of the rotating shaft; each single roller row is uniformly provided with a plurality of hoppers in the circumference direction; all the single roller rows are sequentially arranged in a staggered mode in the same direction; and thus, the hoppers on the whole discharge roller in the corresponding positions are arranged along a plurality of parallel spiral lines in the axial direction. Compared with the prior art, when being used in a continuous retort furnace, the discharge device roller structure can enhance the discharge uniformity, optimizes the discharged material surface curve into small waves from V shape, overcomes the influence of wall effect during material down-going, and enhances the end product quality of clinker.

Description

technical field [0001] The invention relates to a discharge drum, in particular to a drum structure of a discharge device used in a continuous retort furnace. Background technique [0002] In the production process of the continuous retort furnace, the discharge device is a device used to discharge the cooled clinker from the retort chamber. Although the discharge drum of the existing discharge device can simultaneously discharge materials along the length direction of the retort chamber, due to the "side wall effect" between the material and the end wall of the retort chamber, the feeding speed in the middle of the retort chamber length direction is always The feeding speed is greater than that at both ends, so that the temperature in the retort chamber along the length direction is distributed in a "V" shape curve with a low middle and high sides. This temperature distribution is likely to cause uneven raw and cooked clinker and affect the quality of the finished product. ...
