History mesh belt dryer

As early as 1985 laboratory studies were made by J. W. Laird and R. V. Baker which indicated that wire mesh belt conveyor could be used in a cotton drying system.

The first full scale belt dryer was constructed and tested in Arizona in 1991, these belt dryers used a wire mesh belt dryer and had a continuous support beneath the belt. The continuous support included a single diagonal support beneath the belt, also the belt was extended through a chamber with downdraft drying, that is to say heated dry air was introduced above the cotton and the treated air passed through the cotton to outlets below the cotton. In this case, the supports included a diagonal support extending from one side of the chamber to the other. The edge of the wire belt was supported by a support flange running along the sides of the chamber and was held down by a hold down flange extending above the support flange along the sides of the chamber. The exhaust ducts under the belt had a circular cross section with the inlets into the duct at the bottom. The bottom run of the wire mesh belt was supported by the bottom of the chamber and a cross conveyor was located near the inlet end of the chamber to remove trash which was moved to that end by the bottom belt dragging along the bottom of the chamber. A second installation was installed in Texas in 1992. The Texas installation did not include any additional features pertinent to this application.

SUMMARY OF THE INVENTION

1. Progressive Contribution to the Art

This application discloses certain improvements over the previous two experimental installations. Particularly, improvements have been made to cause more trash to be separated from the fibrous material being handled. This is accomplished by intentionally flexing the one-half by one-half modified wire mesh belt dryer. The flexing of the belt will result in shaking the material upon the belt, therefore permitting the release of additional trash.

The belt is flexed sufficiently to cause certain movement of the mass upon the belt without agitating the mass. The normal drying action of the heated air is to be that the heated air flows through the mass of material and not around clumps of the fibrous material. For example: if the flexing of the belt is so vigorous that seed cotton is separated into individual locks, the air tends to flow around the locks. The seed cotton is dried better if the mass of material remains intact with the air flowing through the locks.

The main preferred method of flexing or undulating is by having the belt carrying the mass of seed cotton upon it over intermittent "V" shaped supports. This permits sufficient flexing or undulating to release trash from seed cotton without forming undesirable air passage ways through the mass.

Also, the belt is secondarily flexed by bumper rollers beneath the mass flexing the belt upward at points where otherwise the belt is sagging downward between the intermittent supports. The bumping of the belt is also restricted to cause the flexing to be within the above parameters.

To prevent the trash from building up on top of exhaust air ducts below the belt, the tops of the exhaust ducts are formed by inclined planes which slope sufficiently to permit the trash to slide from the tops rather than accumulate on the tops.

2. Objects of this Invention

An object of this invention is to condition and clean fibrous material.

Another object of this invention is to dry and clean seed cotton in a mesh belt dryer chamber.

Further objects are to achieve the above with devices that are sturdy, compact, durable, lightweight, simple, safe, efficient, versatile, ecologically compatible, energy conserving, and reliable, yet inexpensive and easy to manufacture, install, operate, and maintain.

Other objects are to achieve the above with a method that is rapid, versatile, ecologically compatible, energy conserving, efficient, and inexpensive, and does not require highly skilled people to install, operate, and maintain.
