Description

The present invention relates to a high-capacity sulfur melter.

Known melters. sulfur- they are composed. from a tank equipped with a stirrer and steam heaters.

The solid hay is fed to the melter directly onto the mirror. The disadvantage of known melters is their limited efficiency, since the solid sulfur forms a crust on the surface of the liquid, making it difficult to mix it with liquid sulfur.

The object of the invention is to eliminate the above-mentioned disadvantage (the solution according to the invention has been completely achieved.

The essence of the solution according to the invention is that the melter has two or more agitators, preferably symmetrically arranged, one of which is placed in the hopper and fed with the sulfur of the steel. In the axis of the pan, there is a vertical partition dividing the melter into two chambers, and at one end of the partition, in its lower part, a hole is cut, enabling the flow of sulfur from one chamber to the other. In one chamber there is a hopper with an agitator, and in the second a vertical circulating pump with a capacity of about 10 times greater than the melter's capacity, while the circulating pump and the hopper with the agitator are preferably located as far as possible from the opening in the partition in order to reduce The sludge drogrti the flow of liquid sulfur. For the supply of liquid sulfur to the charging hopper, there was a pipeline connecting the circulation pump to the charging hopper.

(The use of several agitators, one of which is placed in the hopper, prevents the formation of a crust on the surface of the liquid sulfur. This effect is even more achieved by the use of a circulation pump that feeds heated liquid sulfur to the hopper with an agitator, thereby causing this to occur. that the solid sulfur also fed to this funnel is drawn into the bottom of the melter, thereby preventing crust formation on the surface and thus increasing the melting intensity.

Separation of the circulation pump and the charging funnel with the agitator by means of a vertical partition, and cutting a hole in the lower part of the partition, causes the forced flow of liquid sulfur through both melter chambers and thus enables the feeding of liquid sulfur to the the highest possible temperature, which will increase the intensity of melting.

The subject matter of the invention is illustrated in the example of the drawing in which Fig. 1 shows the A-A vertical section of the melter indicated at Fig. 2. Fig. 2 shows a horizontal section of B- (B of the melter in Fig. 1.

The sulfur melter consists of a cylindrical plastic 1 and a conical bottom 2. The inside of the melter is equipped with steam heaters 3, four symmetrically located mixers 4, a foam partition 112 709112 709 dividing the melt into two chambers. The partition 5 has a cut-out hole 6 located at the wall of the melter. In one chamber there is a circulating pump 7 installed to force the circulation of liquid sulfur, and in the other chamber a feed hopper 8 for the supply of solid sulfur. In the hopper 8 one of the agitators 4 is placed. 8 is equipped with a stub pipe 10 for the supply of solid sulfur and is connected by a pipeline 11 to a circulating pump 7, circulating liquid sulfur.

In its upper part, the melter has a stub pipe 9 for discharge from the liquid sulfur melter.

According to the invention, the operation of the melter is that it introduces; the sulfur becomes solid and the hot liquid sulfur circulating in the circuit. Circulating liquid sulfur is fed to the charging hopper by means of a circulating pump • through a pipeline connecting the pump with the hopper.

The mixture of liquid sulfur and solid sulfur is drawn under the liquid surface in the top tube by means of an agitator placed in the hopper and by the hydrostatic glare of a liquid column formed in the hopper.

The mixture of solid and liquid sulfur passes through the circulation of the melting chamber, where, due to the intensive stirring with the blowing of the stirrers and heating with a steam heater, the steel is melted and heated to the desired temperature. Part of the hot and molten sulfur is circulated (a circulation pump is fed to the charging hopper) and some is discharged to the outside via a spigot located at the top of the melter.
