WATER SEAL.

Application nled Hay 4,

tainer with an overflow outlet adapted to be normally closed andwhich will automatically open when the quantity of waterl in the container is increased beyond a predetermined amount due'to clogging of the normal outlet, thereby permitting the escape of the excess water and also warning the operator that the container is clogged.

A. further object is to provide a water seal having the novel construction, design and combination of parts hereinafter described and illustrated in the accompanying drawings.

In the drawings, Figure 1 is a side elevation of a sintering plant embodying the novel features of m invention.

Figure 2 is a en elevation ofthe apparatus of Figure 1.

Figure 3 is an enlarged sectional elevation through one of the gas washers.

Figure 4 is an enlarged side elevation andv Figure 5 is an enlarged end elevation of the water seal mounted on the lower end of the gas washer sludge or drain pipe.

Figure 6 is an enlargedsectional elevatioi through the water seal of Figures 4 an 5.

Referring more particularly to the drawings, the numeral 2 designates the sintering pan which is arranged to tilt o r rock about a horizontal axis, opposite ends of this pan being provided with hollow trunnions 3 3, by which the an is rotatably mounted in suitable trunnlon bearings.

The an 2 has a bottom 5,

sides

6, 6 and integra ly formed ends 7, the hollow trunnions 3-3 opening Ainto the pan through the end walls of the pan. At an intermediate point in the height of the side walls of the pan is a. series of erforated grate bars 8, these bars being he d in position .by transverse perforated supports 8*.

Girders 9, which extend longitudinally along each side of the pan 2, carry flanged track rails 9'l forming a track for charging cars and gas igniters.A

1'923. Serial No. 636,667.

. The outer ends of the hollow .trunnions 3 are connected to one end of pipes 10-10, which form conduits for leading the gaseous products of combustion from beneath the grate bars 8 in the pan 2 into the gas washers 11-11 to which the other ends of the pipes 10-10 are connected.

Pipes 12-12 which are connected to the lower ends ofthe washers 11-11 form condults for leadlng thev cle'aned and cooled gaseous products of combustion from the.

'gas washers to the inlet on the exhaust blower or fan 13, to which the lower end of the ipes 12-12 are connected.

T e exhaust fan or blower 13 is connected by a branch pipe 15 to the lower end of a stack 16 adapted to carry off the gaseous products of combustion.

The washers 11-11 comprise an outer casing or wall 17 having a removable top or head 18 and a removable bottom 19.` The top 18 is provided with a centrally arranged inlet 20, which extends downwardly within the washer for an appreciable distance. The up erend of the inlet 20 is provided with a an e 21, connected to a flange on the end o the pipes 10-10, leading from the f ends of the sintering pan'2.

The bottom 19 is provided with an inclined wall 24 and has a centrally arranged A lower end-with a flange 30 which connects with the flanged upper end of the conduits or pipes 12.

lVater is sprayed into the' stream of highly heated gaseous fluid or burned gases by a series of radial nozzles 31, these nozzles being arranged in the conduit pipes 10-10 above the upper ends of the washers 11, and the baiiies 32, 33 and 34 within the washer cause the said gases and water to travel through a-tortuous path, and com els the gases to pass and repass through t e falling rain of water in the travel thereof through the washer.

The baille 32 comprises a vertical side 35 and an integral bottom 36, the'bottom being conical and being inclined toward the center of thisbale. (See Figure 3.) A small liowingthrough the gas washing 4chamber centrally located outlet opening 37 in the 38, and a series of ribs 39 are formed on the inner surface 'of the side and bottom of this wall, and converge toward the outlet` opening 37 in the tubular extension 38. A plurality of narrow" radial slots 40 are provided in the bottom 36 through which a portion of the water and sludge falls.

The side wall 35 of the balie 32 isspaced from the inlet conduit'26, but extends above the lower edge of this conduit.

vThe third baiiie 34, which is supported on -the upper end of the outlet conduit 26, comy prises a bottom wall 41 which inclines to one side thereof, andthe central portionof the bottom 41 is projected upward in the form of a cone, its apex or peak 42 being located slightly below the lower edge of the depending tubular extension 38 on the batlle 32. An integral rim portion 43 extends around the major portion of the bottom-41,

. being cut away for a space along the lowermost edge of said bottom 41.

The second or intermediate balie 33 is supported on the lower balile 34 and! comprises a tubular body 44 having a flange 45 which extends outwardly and downwardly from the upper edge of the body 44. This iange is provided on its upper surface with a plurality of radial ribs 46, and the flange 45 is only of sufficient diameter to leave a very small annular opening or space between the edge of the flange and adjoining side wall of the washer.

Suitable openings lor manholes are provided in the side walls of the washer, these openings being closed by covers -or heads bodiment of my invention I have shown aA water seal having an inlet 51 at its upper end connected to the pipes 49 and a reduced outlet v52 at its lower end. The out- .let is of materially less diameter than the inlet and is of such a size that it will dis-` charge about the same or less water in a given time than enters the washers 11'. That is, the contracted outlet l.52 must hold back a suiiicient amount of water in the body of the seal member 50 toI form a true water seal. It will, thereforeLbe apparent that the outlet 52 must always be ofl such a size that it will never discharge more water in a given time than enters the washers 11.

of the seal 50' is supported on suitable brackets 53 and is provided with an amount.

overliow outlet 54 provided with a spout or I lip 55 and an inclined hingedy .closure 56.

The closure 56 is provided with a rubber lining or pad 57 adapted to form a tight joint with the seat58 aroundthe outlet 54.

The outlet 52 and overflow 54 are adapted to discharge into a suitable trough 59 leading to a 'suitable sump 60.

In operation the sludge'and water from the washers 11 will be held back in the seal 50 in sufficient quantity to forma liquid seal and prevent the inflow of air through the outlet 52, and if for anyreason the sludge or other foreign matter should clog or partially close the outlet 52 So that the rate of discharge was less than` necessary to carry oil the water and sludge from the washer 11 the water -will rise 1n the seal 50 until it reaches the overflow outlet 54 when it will open the cover or.

bar or similar tooltherein. The operation of-opening the outlet 52 may be readily accomplished without stopping the operation of the plant and wlthout dismantling any ofthe apparatus, and this is quite an improvement over any water seal equipment heretofore used. The inclined mounting of` the closure 56 and the partial vacuum main- 100 tained in the system by the fan 13 combine to normally maintain the closure 56 in closed position.

vWhile I have shown and vdescribed only one specific embodiment of my invention it will be understood that I do not wish to be limited thereto, since various modifications may be made without departing from the scope of my appended claims.

I claim f j 1. The combination with a conduit for conveying liquid, of av liquid seal container secured to .the lower end of said conduit,` said seal container having a contracted outlet at its lower end and an overflow outlet in its side wall at a point above saidcon'- tracted outlet, said contracted outlet-.being of such size as to normally hold back a quantity of liquid in said container to lform a` liquid seal, and said overflow outlet being provided with a hinged closure adapted to normally form av tight joint and to be automatically opened by the pressure of the liquid in said container when its quantity is increased beyonda predetermined,
