Abstract
An improved chute for conveying bulk materials from a higher location to a lower location includes a number of frustoconical hoppers, which are held in vertically-spaced relationship with the conical axes of adjacent hoppers inclined in different directions relative to the longitudinal axis (35) of the chute. The chute is much less liable than prior chutes to cause segregation or degradation of the bulk material being conveyed.
Claims17
An chute for conveying bulk materials from a higher location to a lower location, which chute comprises a multiplicity of frustoconical hoppers, said hoppers being supported, at their outer circumferential edge, upon bands extending parallel to a generally vertical axis of the chute so as to space said hoppers along said generally vertical axis with the axes of adjacent hoppers being inclined to said generally vertical axis in different directions, each hopper having a generally downwardly directed narrower end and a generally upwardly directed wider end, the plane of said lower end of each said hopper intersecting the axis of said hopper at an acute angle.
An chute for conveying bulk materials, which chute comprises a plurality of frustoconical hoppers, said hoppers being supported upon bands extending generally parallel to a generally vertical axis with the narrower end of each hopper projecting downwardly into the wider end of the hopper next below it, the frustoconical axis of each hopper being inclined to said generally vertical axis in a direction displaced around said generally vertical axis relative to the frustoconical axis of said next hopper by an angular amount of about 120 degrees.
A chute for conveying bulk materials, which chute comprises a plurality of frustoconical hoppers, said hoppers being supported upon bands which extend generally parallel to the longitudinal axis of said chute so as to space said hoppers along said longitudinal axis with the axes of adjacent hoppers being inclined to said longitudinal axis in different directions, and wherein the angle of least slope of each said frusto-conical surface, relative to a line perpendicular to said longitudinal axis, is of the order of 45 to 60 degrees.
A chute for conveying bulk materials, which chute comprises a plurality of frustoconical hoppers, said hoppers being supported upon bands extending generally parallel to a generally vertical axis with the narrower end of each hopper projecting downwardly into the wider end of the hopper next below it, the frustoconical axis of each hopper being inclined to said generally vertical axis in a direction displaced around said generally vertical axis relative to the frustoconical axis of said next hopper by an angular amount of about 180 degrees, and wherein the angle of least slope of the frustoconical surface of each said hopper, relative to the horizontal, is of the order of 45 to 60 degrees.
