Specification of Letters Patent.
Patented Mar. 23, 1920.
Application filed November 15, 1919. Serial No. 338,358.
lb all whom it may concern:
Be it known that I, FRANK LIOUD, of St. Etienne, Loire, France, a citizen of the French Republic, have invented certain new Apparatus for the Recuperatlon of \Vaste Fuel, of which the following is a specification.
The invention has for its object an apparatus for the recuperation of the serviceable fuel contained in the refuse of metallurgic establishments, refuse whose yield of fuel varies according to the combustion of coal in the grates of the furnaces, boilers, etc.
This apparatus is specially designed and render its application easier in all factories where the production of some tons of Cinders only present an advantage to the exploiter. v
The apparatuses hitherto devised, for the purpose of submitting cinders to a flowing liquid which carries the bodies along hor1- mentally at speeds in inverse proportion to their density, are so constituted that they convey the matters to be sorted over apertures provided for that purpose, depositing in the latter the densest parts.
i he classification obtained by this simple method only gives appreciable results for the treatment of cinders produced from the smith coal, but when it is a question of treating cinders produced from unwashed coals, or of separating the refuse proceeding from boilers and forges where the density of the slate, cinders and impersame, classification then becomes impossible.
in the present apparatus the products to be classified are fed onto a semi-cylindrical plate, which introduces them into the sorter, and are conveyed by a liquid stream flowing horizontally from right to left in the apparatus.
The action of gravity draws the products vertically down to the bottoms of the cases arranged at different distances and heights in the apparatus, and a series of currents of water entering through the bottom of the apparatus, forces the products from below upward; the said currents which. are suit- {it}; ably regulated, are intended to lift part of the substances which fall and to return them into the sorting cones.
'lhe regulation of these different currents terms in the upper layers of the liquid, :1
sorting zone Where the separation of the coke, the slate and cinders is effected.
The products which cannot be thrown off by the rising currents of water (cinders and slate) descend into empty parts provided along the apparatus, whereas the cokes pass to the lower part of the sorter, describing parabolas in proportion to their densities in the currents of water which convey them.
The fuel is collected on a grating, the parabolic shape of which allows of the second raising of the Waters in a decantin basin and the evacuation of the recuperated products by trucks. The sterile matters are evacuated y a chain of buckets communieating with the apparatus through an opening provided at its base.
he arrangement of the various members composing said apparatus is clearly indicated by the annexed drawing which represents:
Figure 1 a section of the classifier on the line 1-l of Fig. 2.
Fig. 2 is a plan thereof.
Ji Fig. 3 a cross section on the line 3 3 of The apparatus comprises a rectangular trough a having a base 6 forming a triangular case, as shown in Fig. 1. At one end of said trough is a collector c for the evacuation of the recuperated products and at the other end a bucket conveyor d for the evacuation of the waste.
At the center of the apparatus is an iron plate 6 of. rounded form, which forms a lid of the trough f into which water is admitted regulated by the valve 9.
At the end of the plate c are arranged at more or less distances apart, several iron plates It arranged vertically, of which the upper ends are bent over and form a series of decreasing curves a".
The rounded plate a is perforated at its lower part so as to cause the water which passes through the perforations to form a series of, jets, which convey parabolically the matters to be sorted toward the different evacuation apertures.
The compartments formed at determined intervals is in front of each of the movable curved plates 1 form a series of chambers into which water under pressure is introduced, this admission of water bei regulated in each chamber by a valve 3.
The ascending current is suitably regulated so as to enable the heavy matters, which travel horizontally and fall, owing to their weight, into the free spaces, to be less sensitive to the pressures and pass into the vat, while the coke will be conveyed by the horizontal current to the end of the apparatus, to be thence thrown out through the outlet conduit 0.
The plate m situated in front of the outlet is movable and serves to form inside the apparatus a massof standing water above the rounded plates 71 which facilitates the sorting of the products.
At the bottom of the trough is applied a triangular case b, in which is a bucket conveyed d evacuating the sterile products through a strainer n.
The parts a and b communicate with each other through the opening 0. In the apparatus the water discharged with pressure through the openings of the plate e conveys the products from the hopper p and causes them to describe parabolas varying according to the density of each body: the form of said parabolas is approximately represented on the drawings by arrows, and the direction of the currents of Water by arrows shown in broken lines.
What I claim as my invention and desire to secure by Letters Patent of the United States is 1. An apparatus for the classification of Waste fuel, comprising a tank, a partially perforated metal plate therein, means for causing the material to be classified to fall onto said plate, means for supplying water under pressure behind said plate so as to pass through the perforations thereof into said tank, a series of solid curved iron plates in said tank, a series of compartments one in front of each of said solid plates, means for regulating the admission of water under pressure into the bottoms of said compar'tments which flows upward therein, the water fed through said perforated plate flowing horizontally over the tops of said compartments, whereby the ascending currents of water enable the heavy matters to fall into said compartments and pass to the bottom of said tank, and the horizontal currents convey the li hter matters to the extremity of said tan means for evacuating said lighter matters and means for evacuating said heavy matters.
2. An apparatus for the classification of waste fuel comprising a tank of triangular shape, a feed hopper above said tank, a collector for the evacuation of the recuperated products at one end of said tank, a bucket conveyer at the other end of said tank, a.
trough arranged centrally and transversely in said tank, a partially perforated curved plate forming a lid for said tank, means for supplying water under pressure to said trough, a series of solid curved plates of gradually decreasing curvature arranged in said tank in front of said perforated plate, a series of compartments between said solid plates, valves in saidcompartments and a movable plate arranged in said tank adjacent said collector for maintainin a mass of water above said solid curved ates.
In witness whereof I have signed this specification in the presence of two witnesses.
FRANK LIOUD.
