Benefits of technology

The patent text describes a device called a conveyor-tightener that prevents material from accumulating and settling in the spaces between helical flights in a conveyor system. This is achieved by using air pressure to fluidize the material and prevent it from getting stuck. This device improves the flow of material and prevents blockages in the conveyor system.

Problems solved by technology

In the use of an auger in conveying fine bulk materials, it has been found that such usage results in an unsteady and uneven flow of materials, and even stoppage due to clogging.
Such effects have been found to be caused by the accumulation and settlement of fine material particles in the spacing between helical flights which diminishes and possibly blocks the flow of material through the conveyance device.
The result of such accumulation and settlement of material particles is a loss of capacity due to material accumulation diminishing the space between helical flights, and a reduction in the uniformity of the material being conveyed due to the detachment and discharge of segments of material lodged in helical flights.

Embodiment Construction

[0014]Referring to the drawings, there is illustrated an embodiment of the invention, generally including an assembly 10 for conveying a fine bulk material gravity fed from a vessel 11 and discharged into a conduit 12. Assembly 10 includes an inner, tubular conduit 13 formed of an impermeable material, an intermediate tubular conduit 14 formed of a permeable material encompassing, spaced from and disposed coaxially relative to inner conduit 13 and an outer tubular conduit 15 also formed of an impermeable material encompassing, spaced from and also disposed axially relative to inner conduit 13.

[0015]Inner tubular conduit 13 includes an axially disposed fluid passageway 16, having one end as shown in FIG. 5 extending through an opening in a side of conduit 12 and journalled in a mounting provided on an opposite side of conduit 12, and an opposite end as shown in FIG. 6, provided with a stub shaft portion 18 having one end thereof extending into and closing an end of passageway 16 and ...

Abstract

An apparatus for handling a fine bulk material including a tubular member formed of a gas permeable material, a tubular member formed of a gas impermeable material encompassing the first mentioned tubular member, having an inlet and outlet at opposite ends thereof, a helical member mounted on the first mentioned tubular member, means for rotating the first mentioned tubular member and means for injecting a fluid under pressure through the first mentioned tubular member into the annular passageway disposed between such tubular members including the helical member, precluding the settling of material being conveyed in such passageway.

Description

[0001]This invention relates to an apparatus for handling fine bulk material and more particularly to an apparatus for conveying such material by means of an auger shaft at a steady and even flow rate.BACKGROUND OF THE INVENTION [0002]In the use of an auger in conveying fine bulk materials, it has been found that such usage results in an unsteady and uneven flow of materials, and even stoppage due to clogging. Such effects have been found to be caused by the accumulation and settlement of fine material particles in the spacing between helical flights which diminishes and possibly blocks the flow of material through the conveyance device. The result of such accumulation and settlement of material particles is a loss of capacity due to material accumulation diminishing the space between helical flights, and a reduction in the uniformity of the material being conveyed due to the detachment and discharge of segments of material lodged in helical flights. The deeper the spacing between h...
