A volume-adjustable discharge device drum structure and its application method

Abstract

The invention relates to a discharging device roller structure with the adjustable volume and an application method of the discharging device roller structure. The roller structure is provided with a plurality of hoppers in the axial direction. Each hopper is internally provided with a volume adjusting device. The part between an inner circle and an outer circle of the roller structure is divided by two side plates into discharging space, wherein the two side plates are arranged in the longitudinal direction of the roller structure and are parallel to each other. The discharging space is divided by a plurality of partition plates into the multiple hoppers, wherein the partition plates are arranged in the transverse direction of the roller structure. The distance between the two side plates, namely the width of the hoppers is smaller than the width of a feeding port of a discharging device. Each volume adjusting device is composed of an adjusting plate, a spring, a screw and a nut, wherein the screw is fixed to the inner circle in the corresponding hopper, the spring is arranged between the adjusting plate and the inner circle, the top of the adjusting plate is fixed through the nut, and the size of the adjusting plate is matched with the size of the section of the corresponding hopper. The local discharging amount of the discharging device can be adjusted at any time according to the actual production situation through the discharging device roller structure, evenness of the overall discharging amount is guaranteed, the uniformity of the furnace temperature can be better improved, and the finished product quality of clinker is finally improved.

Description

technical field [0001] The invention relates to a discharge drum, in particular to a volume-adjustable drum structure of a discharge device and a use method thereof. 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. The Chinese patent application number 201410466648.2 (application date is November 4, 2015) discloses "a low-rank pulverized coal continuous carbonization process and device". In the thermal continuous retort furnace, the raw coal gas is collected through the gas collection device and the gas collection chamber and exported from the gas collection system; the charge after retort is discharged through the discharge device; there are two types of discharge device, the discharge device is one The powdery charge is discharged through the coke discharge drum; the discharge device is composed of a shell, a rotating shaft, a coke discha...

AI Technical Summary

Problems solved by technology

[0003] Although the discharge drum of the above-mentioned discharge device can discharge material uniformly along the length direction of the retort chamber in principle, in the actual production process, due to uncertain factors, the discharge speed at a certain position in the length direction will be too slow or relatively slow compared with the overall discharge rate. Too fast, because the discharge volume of the discharge drum cannot be adjusted locally, and the furnace temperature will still be uneven due to the uneven discharge volume, which will affect the quality of the finished product
