ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a storage bin of the type comprising a horizontal circular base with a cylindrical peripheral wall upstanding from the base which is generally used for storing particulate materials such as grain and other crops.
BACKGROUND
Many such bins are formed by a concrete base with the peripheral wall formed from corrugated panels bolted to and standing upwardly from the edge of the concrete base.
However the requirement for the concrete base is relatively expensive and restricts the possibility for movement of the bin from place to place as requirements change.
It is known therefore to provide a base formed from sheet metal panels with an upstanding cylindrical floor section which provides a base for the remaining wall of the bin.
SUMMARY
It is one object of the present invention to provide an improved bin floor structure which assists in ready transportation of the floor structure to a site for installation.
It is a further object of the present invention to provide an improved aeration system for use in a bin of this type.
It is a further object of this invention to provide an improved discharge system for a bin of this general type.
According to the present invention there is provided a storage bin comprising:
a bin floor structure having a circular horizontal support surface;
a cylindrical bin wall upstanding from the support surface;
and a bin aeration system for injecting air into a material stored in the bin, the aeration system comprising:
a perforated air discharge tube;
a support member extending substantially diametrically across the bin from one side to an opposed side and supporting the air discharge tube with its axis extending substantially diametrically across the bin at a height in the bin spaced upwardly from the support surface;
and an air supply duct for supplying air from a fan through the wall into the air discharge tube for escape from the tube into the material in the bin.
Preferably the air supply duct extends partly into the bin from one side wall portion of the bin.
Preferably the air discharge tube has ends thereof terminating at a position spaced from the wall of the bin and is arranged substantially symmetrically such that the ends are substantially equal distantly spaced.
Preferably the support member comprises a pair of rails each extending parallel to and each spaced on a respective side of the axis.
Preferably the support member has a pair of end supports extending vertically upwardly along a respective side wall portion of the bin wall.
Preferably the end supports comprise a pair of legs each extending vertically upwardly to a respective one of a pair of rails defining the support member.
According to an aspect of the present invention there is provided a storage bin comprising:
a bin floor structure having a circular horizontal support surface;
a cylindrical bin wall upstanding from the support surface;
and a bin discharge system for discharging material stored in the bin from the bin to a position exteriorly of the bin, the discharge system comprising:
a discharge duct having a material transport member within the duct for transporting the material along the duct;
the duct extending from a feed opening adjacent a center of the bin upwardly and outwardly through an opening in the wall of the bin at a height spaced upwardly from the floor structure;
and a base member extending from the horizontal support surface to the duct and defining two side walls each arranged on a respective side of the duct and extending from the duct downwardly and away from the duct such that the interconnection with the base and support surface is wider than the duct and tends to shed the material outwardly away from and an area underneath the duct.
Preferably there is provided a recess at the center of the support surface defining a floor hopper into which the material can fall and wherein the duct has the feed opening thereof extending into the floor hopper.
Preferably a portion of the duct adjacent the feed end thereof projects into the recess and wherein the side walls extend from the wall of the bin to a position where the duct enters the recess.
Preferably there is provided a bin sweep which moves around the bin to a position adjacent each side wall of the base member for carrying the material from the support surface to the feed end of the duct.
According to an aspect of the present invention there is provided a storage bin comprising:
a bin floor structure having a circular horizontal support surface;
a cylindrical bin wall upstanding from the support surface;
and a bin discharge system for discharging material stored in the bin from the bin to a position exteriorly of the bin, the discharge system comprising:
a discharge duct having a material transport member within the duct for transporting the material along the duct;
the duct extending from a feed opening at a center of the bin horizontally under the horizontal support surface to a discharge outside the wall of the bin;
the material transport member comprising a belt having an upper run along the duct.
Preferably the duct is rectangular so as to receive the upper and lower runs of the belt across the width of the duct.
Preferably the duct has a first slide gate at the center of the bin and the second slide gate approximately midway between the center of the bin and the side wall of the bin.
Preferably the belt is mounted on a belt conveyor system which allows the belt to be removed from the duct to an opening at the end of the duct at the edge of the floor structure.
Preferably the belt includes an elevator section at an end thereof outside the bin for discharging the material from the bin into a main conveyor.
Preferably the storage bin includes a bin sweep.
According to an aspect of the present invention there is provided a storage bin comprising:
a bin floor structure having a circular horizontal support wall and a cylindrical peripheral wall standing upwardly from and attached to the support wall around and at a periphery thereof;
a cylindrical bin wall attached and upstanding from a top edge of the peripheral wall of the floor;
the floor structure and the wall being formed of sheet metal;
the floor structure being divided diametrically into two separate half sections.
Preferably the support wall of each half section having a flange along an edge thereof for bolting to a flange of the other section, the flange is projecting downwardly below the horizontal wall.
Preferably each flange comprises a web of an angle iron with another web of the angle iron attached to the edge of the support wall.
Preferably the peripheral wall of each half section has an edge abutting the edge of the peripheral wall of the other half section and is bolted thereto by a joining plate.
