圆管胶带输送机是竖井提升煤炭的一种新方法。为了保证满负荷提升，必须提高物料的充填密度。为解决这一问题，作者提出了圆管胶带运输机的气力喂谋系统，它包括物料的粗筛分、发送和除尘装置；综合散料力学、流态化和气力输送理论并结合物料的性质，阐述了系统的发送理论和计算方法。为使发送更可靠，系统中还加置了旋转射流的推进装置。实验表明，系统的发送能力比单纯重力发送时提高近一倍。
Tube Tape Conveyor is a new way for shaft to raise coal. In order to ensure full load, we must increase the packing density of the material. In order to solve this problem, the author put forward the pneumatic feeding system of the round tube tape conveyor, which includes the raw material screening, sending and dust removal device. Based on the theories of bulk material mechanics, fluidization and pneumatic conveying and the properties of the material, Elaborated the system transmission theory and the computation method. In order to make sending more reliable, the system also adds a rotating jet propulsion device. Experiments show that the sending capacity of the system is almost double that of sending by gravity alone.
