A drum structure of a discharge device

Abstract

The invention relates to a drum structure of a discharge device, including a discharge drum, the discharge drum is composed of a plurality of single-row drums arranged axially on a rotating shaft, and several hoppers are evenly arranged on each single-row drum along the circumferential direction. Each single-row drum is arranged alternately along the same direction; that is, the hoppers at the corresponding positions on the entire discharge drum are arranged in multiple parallel helical lines along the axial direction. Compared with the prior art, the beneficial effect of the present invention is: it is used in a continuous retort furnace, which can improve the uniformity of material discharge, optimize the curve of the material surface after discharge from a "V" shape to a small wave shape, and overcome the downward flow of materials. The impact of the side wall effect can improve the quality of clinker products.

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. ...
