Abstract

Provided herein is a powder feeding device and a calciner. The powder feeding device includes a feeding barrel, one end of the feeding barrel is provided with an inlet for entering powder, and the other end of the feeding barrel is provided with a feeding The outlet from which the powder flows out; the feed cylinder takes the inlet as the starting end, and is provided with a first material distribution area, a second material distribution area and a third material distribution area in sequence along the axial direction; wherein, the first material distribution area There is a first included angle with the vertical direction, a second included angle between the second material distribution area and the vertical direction, a third included angle between the third material distribution area and the vertical direction, and the first included angle Angle<the second included angle≤the third included angle. The embodiment of the present application effectively improves the spreading degree of the powder and improves the uniformity of the powder feeding.

Description

technical field [0001] This article relates to, but is not limited to, the technical field of sheet metal production equipment, in particular to a powder feeding device and a calciner. Background technique [0002] The calciner is a common equipment for calcining gypsum powder. It is often calcined by hot oil, so that the temperature of the powder flowing out of the calciner can be as high as about 150 °C to ensure the performance of the gypsum board product. [0003] In the process of calcination of commonly used calciners, the problem of partial over-calcination of powder or insufficient calcination of part of powder often occurs, which in turn leads to a decrease in the mechanical properties of gypsum board. [0004] It should be noted that the above content belongs to the technical cognition category of the inventor, and does not necessarily constitute the prior art. SUMMARY OF THE INVENTION [0005] An embodiment of the present application provides a powder feeding d...
