Abstract A method of solidifying molten sulphur involves forming on a belt at least one undulation which is shaped to permit the formation of a pool of molten sulphur. Molten sulphur is fed onto the belt so that a pool is formed on the undulation. The speed of the belt is controlled in relation to the feed rate of the sulphur and in relation to the angle and length of the surface of the undulation remote from a feeding section for the sulphur so that molten sulpur is caused to form into a layer and solidify on the belt as it passes through the pool. Cooled or partially cooled sulphur is then delivered from the surface of the belt. The angle of undulation extending upwardly and away from the feeding section is normally within the range of one half a degree to about three degrees. Apparatus for use in the solidification of molten sulphur is also provided. A cooling tank assembly provided with a plurality of generally transversely disposed baffles includes means for directing a supply of air into the assembly with an air deflector embodied in the cooling tank structure.

Claim 1
Independent Claim
102 words
APPARATUS FOR THE SOLIDIFICATION OF MOLTEN SULPHUR COMPRISING: A. A MOVABLE ENDLESS SUBSTANTIALLY HORIZONTAL BELT FOR SUP PORTING A LAYER OF MOLTEN SULPHUR THEREON B. MEANS FOR FEEDING MOLTEN SULPHUR ONTO THE NORMALLY UPPER SUPSURFACE OF SAID MOVABLE BELT AT A FIRST OF A PLURALITY OF POOLS OF MOLTEN SULFUR: C. A SUPPORTING STRUCTURE DISPOSED BENEATH THE UPPER SURFACE OF SAID BELT SO AS TO DEFINE AT LEAST THREE UNDULATIONS ARRANGED IN PREDETERMINED SPACED RELATIONSHIP ALONG THE LENGTH OF SAID BELT, SAID UNDULATIONS BEING SUCH AS TO PERMIT THE FORMATION OF SAID PLURALITY OF SEPARATE AND DISTINCT POOLS OF MOLTEN SULPHUR THEREON:

Claim 3
Dependent Claim
23 words
Apparatus as claimed in claim 1 wherein the angle of the inclinations in said undulation ranges from about 1/2 * to about 3*.
Claim 4
Dependent Claim
18 words
Apparatus as claimed in claim 1 wherein the angle of the inclinations in said undulation is about 1*.
Claim 5
Dependent Claim
51 words
Apparatus as defined in claim 1 including a perforated member is disposed transversely of said movable belt in the vicinity of the feeding end thereof, said perforated member being adapted to provide a supply of water to the upper surface of said belt and maintain it in a generally wetted condition.
Claim 6
Dependent Claim
47 words
Apparatus as defined in claim 4 wherein a felt doctor is associated with said perforated member in such a way that the water delivered from said perforated member is sufficient to saturate said doctor so as to maintain the surface of said belt in a wetted condition.
Claim 7
Dependent Claim
39 words
Apparatus as claimed in claim 1 including means for cooling said molten sulphur to a temperature of between about 255*F and about 265*F and means for feeding said cooled molten sulphur to the normally upper surface of said belt.
Claim 8
Dependent Claim
35 words
Apparatus as claimed in claim 1 including a tank structure shaped to house said apparatus and maintain a bath of water therewithin including means for recirculating the water and reintroducing the water into the tank.
Claim 9
Dependent Claim
38 words
Apparatus as claimed in claim 7 including means for cooling the recirculated water said means being disposed intermediate the point of extraction of the water from said tank and the point of the introduction of said water thereto.
