Patented May 23, 1916..

Application led February 8, 1915. Serial No. 6,765.

To all whom z't may concern:

Be it known that I, LARs LARso-N, a citizen ofthe United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Slag-Disintegrating Apparatus, of which the following is a specification.

My invention relates to improvements 41n slag disintegrating apparatus, and has for its object the production of mechanism of this character whichv will be of improved construction and efficient in operation.

A further object is the production of slag disintegrating apparatus in which the cooling of the slag before disintegration will be effected without the necessity of subjecting the molten slag to the direct action of water.

Other objects will appear hereinafter.

Theinvention consists in the combinations and arrangements of parts hereinafter described and claimed. y

The invention will be best understood by reference to the accompanying drawings forming a par-t of this specification, and in which i Figure 1 is a side elevation of a slag'disintegrating apparatus'embodying my invention, Fig. 2 is a top plan view of the same, Fig. 3 is a section taken on substantially line m-.r of Fig. 1, Fig. 4 is an enlarged central vertical section of one end of the apparatus, and Fig. 5 is an enlarged detail section taken on line g/-jz/ of Fig. 4. y

The preferred form of construction, as illustrated in the drawings, comprises a reservoir l into which the molten slag to be treated is deposited. The reservoir 1 is provided at its front end with an outlet opening 2 which is controlled by a vertically slidable gate valve 3 which is mounted between guide flanges 4 provided upon the front wall of said reservoir. The front end of the reservoir is reduced at the approach thereof to the discharge opening 2. The gate valve 3 m is manually controlled by means of a stem for moving the p jected at one end for the accommodation of a pulley 13, as clearly shown in Fig. 2, through the medium of which connection may be made for driving the same. Mounted fortravel around the sprocket wheels 11 and 12 are two spaced endless sprocket chains 14.

Arranged upon the inner sides of the lateral walls of tank 8 are inwardly projecting angle irons 15 for engagement with the under `sides of chains 14 to support the same in the travel of said chains, as will be readily understood.

,Arranged between the chains 14 is a plurality of flat rectangular plates 1G arranged edge to edge, the lateral edges of said plates having upwardly turned flanges 16 which are fastened to said chains, as shown. Re* inforcing angle irons 17 are provided at the under sides of plates 16 to prevent warping or sagging of said plates, as will be readily understood. Provided at the front edge of each plate 16 is a downwardly oset iange or lip 18 adapted to overlap with or engage under the rearward edge of the next forward plate, as clearly shown in Fig. 4, in order to maint-ain said plates in proper alinement and prevent the forward edge of any of said plates projecting above the rearward edge of the next forward plate, the reason for this precaution being hereinafter setforth as will appear. The arrangement is such, as will be seen, that an elongated longitudinally movable endless platform is constituted by the chains 14 and the members 16 which, when the apparatus is in use, passes immediately below the outlet opening of the reservoir 1.

Arranged below the upper portion of the endless platform immediately forward of the outlet opening of the reservoir 1 is a spraying nozzle 19 which is constituted by a substantially U-shaped pipe having openvthat is the plates 1G.

ings at its upper side through which the cooling liquid supplied to said pipe is adapted to pass in the form of a great number of small streams or sprays for contacting with the under sides of plates 1G` in order to cool the same. The nozzle 19 is connected at one end with a supply pipe 2O which leads to any suitable source of cold water supply. A

atr23 to one end of the bottom of theV trough 22 is a plate 24 so arranged that the outer or free end thereof rests loosely upon the upperside of the traveling platform, In order to insure a close engagement between the upper sides of Y said plates and the front edge of said plate 24. the under side of said edge of said plate it beveled, as clearly shown in Fig. 4. Also arranged at the entrance end of the trough 2'2 are divergent laterally projecting plates Q5 secured. by means of bolts 26 and cooperating -nuts, to supporting plates 27 rigidly secured to suitable adjacent supporting structure. The bolts 2G engage vertically extending elongated slots 2S formed in the plates Q5. as clearly shown in Fig. 5, which permit of vertical adjustment of said plates in order to adjust the lower edges thereof relative to the upper side of the platform.

In the operation of the apparatus, the slag which is deposited upon the platform from ythe outlet opening of the reservoir l will be cooled by reason of the cooling of the plates 1G through spraying thereof by the nozzle 19'. As the cooled and therefore hardened slag reaches the plates 24 and 25, the same will be scraped thereby from the upper side of the platform and directed toward the entrance end or mouth of trough 92. In order to insure the thorough scraping of the platform by the plates 25, the lower edges of the latter are bent forwardly at an angle, as clearly shown in Fig. 5, said bending of said edge rendering the removal of the slag from t-he platform more easy and with less resistance. lips 1S at the front edges of platform plates 16, the possibility of engagement of said edges of said plates with the scraper plates 24; and 25 is precluded since. as above'pointed out, with this construct-ion it is impossible for said edges of said plates to project above the rearward edges of the next forward plates. Arranged above the respective ends of trough QQ are shafts Q9 and 30 upon which are mounted pairs of spaced sprocket wheels 81 and 32I respectively. Traveling Through the provision of the around the sprocket wheelsl and 32 are two spaced sprocket chains 33'upon which are carried scraper members or buckets 8l adapted` upon movement of the chains 33 to successively enter and travel along the trough 22 in order to carry the slag directed V the adjacent lateral walls of the trough and' thus interfere with the free passage of said buckets through'the trough. The shaft 30 is extended at one end to accommodate a -pulley 37 through which attachment may beV made to a source of power for driving of said shaft, as will be Vreadily understood. The slag which is carried rearwardly in the trough 22 by the buckets 35 when carried beyond the rearward' end of said trough dropstherefrom into a hopper 38 arranged below said end of said trough, as clearly shown in the several views. Arranged at the lower end of said hopper are disintegrating rollers 39 through the medium of which the slag, which is deposited into said hopper will be crushed or granulated to the desired degreepof tineness, as will be readily understood. The endless platform is of such length that there is considerable slack inthe Y This compartment in the operation of the apparatus is supplied with cooling water and therefore in the passage of the platform through said compartment, said platform will be subjected to a bath to effect cooling of the same. An over-flow pipe 40 is provided in the side of compartment 8 forV de'-l termining the level of the cooling water con* tained therein anda drainpipe 41 registers with the bottom of said compartment for entirely draining the same when desired 'in order to remove any sediment which may gather therein.

In order to insure against the lodging'of any particles of slag or foreign matter upon the lips or flanges 1S so as to thus prevent proper seating of the rearward edges of the to effectively clean the joints between the plates before the same are closed which occurs immediately after said plates pass from engagement with the sprocket wheels 1l. The nozzle 42 is supplied with water through a pipe 43 which connects with the supply pipe 20. The arrangement is such, as will be seen, that the valve 2l serves as a control for both nozzles 19 and 42. The water which is discharged from said nozzles drips down the sides of the tank 8, accumulating in the cooling compartment 8 which is thus supplied With the water for cooling at this point, as above described. The bottom of the tank 8 is. inclined in both directions toward the compartment l8 so that the water will readily drain into the latter.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without depaiting from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of suoli variations and modifications as come Within the scope of the appended claims.
