DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to means and method for feeding interlocking solid material to process apparatus and, more particularly, to means and method for feeding shredded tires to a tire liquefaction process apparatus.
SUMMARY OF THE INVENTION
The present invention is a purge chamber which includes a chamber for holding interlocking solid material. An entrance port apparatus passes the interlocking solid material into the chamber where it is purged by a purging gas. An exit port apparatus passes the solid interlocking solid material from the chamber. Located within the chamber is moving apparatus which moved the interlocking solid material from the chamber through the exit port apparatus. Further, located within the chamber, is yet another apparatus which prevents the binding of the interlocking solid material.
The objectives and advantages of the invention will appear more fully hereinafter from a consideration of the detailed description which follows, taken together with the accompanying drawings, wherein one embodiment of the invention is illustrated by way of example. It is to be expressly understood, however, that the drawings are for illustration purpose and are not to be construed as defining the limits of the invention.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a graphical representation of apparatus, constructed in accordance with the present invention, for the purge feeding of interlocking solid material to process apparatus.
FIG. 2 is an isometric view of the chamber shown in FIG. 1.
DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 and 2, there is shown apparatus for the purging of interlocking solid materials in a sealed chamber. The phrase "interlocking solid material" refers to solid substances that, because of their shape and/or composition, have a strong tendency to knit together like entangled yarn. While the primary example of the present invention is related to discharging shredded tire pieces, other applications, such as woodchips, reinforced plastics and scrap may also be applicable.
In the discharging of shredded tire material to feed a tire liquefaction process, as described and disclosed in U.S. patent application Ser. No. 08/053,727 filed Apr. 27, 1993, the shredded tire material is contacted with oil at a temperature of 700.degree. F. It is required, therefore, that the material be purge of oxygen prior to introduction into the liquefaction reactor. The present invention is for apparatus and method for doing that.
A chamber 3 with a top feed port 7 has support members 15 to give it greater strength. Located within chamber 3 are hanger bars 22 which are used to support a material drive system including a drive motor 27. A drive shaft 36, rotated by motor 27, is connected to a gear reducer 44. Gear reducer 44 also provides a 90.degree. F. translation of the driving force to another drive shaft 52. Associated with drive shaft 52 is a bearing 56 mounted on a mounting plate 58 being held in place by support members 65. At the bottom of chamber 3 is an exit port 72.
Connected to drive shaft 52 is a screw auger 80. By way of example, screw auger 80, preferably turning at 20 revolutions per minute, might have a 10-inch diameter centered over a 16-inch outlet port 72. Arranged on either side of screw auger 80 are a pair of cylinders 88 having a plurality of lugs 96 mounted in a predetermined manner thereon. It should be noted that the bottom of chamber 3 is curved so as not to create any dead space between the lugs 96 on cylinder 88 and the bottom of chamber 3. Motor drive means for rotating cylinders 88 on axles 104 are not shown but their location would be obvious to one skilled in the art. The rotations of cylinders 88 may be any one of a combination of three movements with both cylinders 88 being rotated counterclockwise or having one cylinder being rotated clockwise and the other cylinder being rotated counterclockwise. Cylinder 88 may be rotated at a rotational speed that may be from 1/10th to 1/2 the speed of screw a
