THOMAS J'. DAVIS, OF BUQUES-NE, IENNSYLVANIA.
SINTERING APPARATUS.
. application fuedmay 29, 1923. serial No. 642,190.
y To all 'whom it may concern:
Be it known that I THOMAS J. DAVIS, a citizen of the United States, and resident of Duquesne, in the county of Allegheny and State of Pennsylvania, have invented cer- .tain new and useful Improvements in Sintering Apparatus, of which the following is [ai specification. Y
This invention relates to sintering apparatus and more particularly to sintering apparatus employing a sintering pan adapted to be tilted about a ixed axis to discharge v the sintered material, and has for its object the provision of means for trapping and preventing the escape of the dust caused bydischarging the sintered material from the pan. i
Another object is to provide a sintering f' apparatus having the novel construction7 :position to discharge the sintered material therefrom.
' or ot 'design and combination of parts described in the following specification and illustrated in the accompanying drawings.
In thel drawings- Figure 1 is a somewhat diagrammatic top plan of a sintering plant constructed in accordance with my invention.
Figure 2 is a side elevation thereof.
Figure 3 is a sectional elevation on the line III-III of Figure 1.
Referring more particularly to the rdrawings, the sintering plant is shown composed of two buildings, 2 and 3, of' ordinary construction, each of which is provided with a charging loor 4. 1
A pluralityV of sintering paris 5, of well known construction, such as illustrated and described in the United States patents to Greenawalt, No. 1,098,033, dated May 26, 1914, and No. 1,110,623, dated September 15, 1914, are mounted in a series of-openings the oors 4. The pans 5, as 1s well iiiown in the art and as described in the Greenawalt patents, are adapted to rotate about avixed axis into a tilted or inverted Suitable receiving bins -"2' are built below each of the pans 5. The bins 7 are each provided with a rscreening member 8 adaptedto separate the' coarse and fine pieces of sintered material, the coarse material flowing over the screen 8 and being discharged from the o en lower end of the bin into a car 9 Ilier conveyance which is positioned alongside the plant, While the line material passes through the screen and' is retained in the bin, the lower end of which is closed as at 10 up to the screen 8. A hopper 11 isy provided adjacent the lower end of each of the blns 7 to permit the discharge ofthe ac cumulated fine material.
The bins 7 project through the side wall of the buildings housing the plant, and terminate in a car house 12 which forms a continuation of the main building and is secured thereto. The car houses extend the entire length of the main building and mayr or may not have their ends closed, as deslred.
The charging floor ,4 is provided with a track 14, the rails of which are on the opposite sides of the pans 5. .The track 14 is adapted to have suitable charging buggies, igniter cars, etc., run thereon, and suitable hoods or covers 16 are also mounted on the track 14 and adapted to be moved over the pans after the sintering operation is completed and prior to discharging the sintered material.
The hoods 16 are adapted to seal with the charging floor and thus prevent the escape of dust from the discharged sintered materialupwardly through the building.
yThe bins 7 and car houses 12 form enclosures to receive the discharged material and,
therefore, all the dust created by discharging the sintered material is retained and prevented from scattering over the surrounding country as is now customary.
In order to remove the dust from the bins 7 and'car houses 12, I provide an exhaust fan 18 which has its exhaust or inlet port end thereof. One of the' branch vconduits is u preferably provided for each of the pans 5 and the nozzle portions 22 are preferably located over the receiving cars 9 and adjacent the upper ends of\ the bins 7, respectively.
'Ehe dust catchers 24 will remove the dust from the exhausted air before it reaches the fan 18. and prevent it from being discharged through the stack 25 which receives the ex- O haust from the fan 18.YV
| ately below each branch conduit 21.
Suitable dry dust catchers 26 are also provided at intervals along thefmains 19 and 20. of these dust catchers -is provided immedidust catchers 26 may be 'of any standard design andare adapted to catch the heavier dust particles which settle in\the mains as Y the air is drawn through the branch conduits 20 into the mains.
,In operation, after the material in the pan 5 has been -completely sintered the hood 16 is moved into position over the pan so as to f seal with'the 'floor 4 and the pan is tilted or rotated about its axis in the usual manner to discharge its contents into the bin 7. As thematerial falls into the bin 7 it will be intercepted by the screen 8 and the coarse and line 'particles separated,the
0 coarse particles being discharged into the dust from the bin 7 and car house 12 and.
cause it to beltrapped in the dust catchers.
It will, therefore, be apparent f that the present inventionv will effectivelyI overcome 'the' objections to the plants as prevlously constructed and, therefore, it is a considerable improvement over the art.
