The invention relates to the industrial use of building materials, mineral fertilizers and metallurgical industry and can be used for the processing of blast-furnace electro-thermophosphoric, electrothermal sulphate, ferroalloy and cupola slags into a gravel-like slag pumice.

The purpose of the invention is to increase productivity and increase the reliability of a device for producing gravel like slag pumice, as well as improving the quality of prod.

Figure 1 shows the device, a general view; FIG. 2 shows the node I in FIG. one; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 1; figure 5 - node II in figure 1.

The device contains a water-air foil consisting of a hydro-chute, 1, an air nozzle 2, and a chamber 3 times the rumble covered by the water jacket 4.

Water on the shirt two longitudinal partitions 5 is divided in height into two cavities - upper and lower. Two nozzles are embedded in the wall of the water jacket near the hydraulic groove. The inlet pipe 6 is embedded in the lower cavity, the outlet pipe 7 is in the upper cavity.

bath cooler 10. Near the outlet opening of the acceleration chamber from the upper and lower cavities of the water jacket, two tubular arms 11, interconnected by a tubular bridge 12, are elevated at an acute angle to its axis. Thus, the lower cavity is connected through the tubular consoles and bridge. from the top. In the wall of the tubular lintel along its axis are placed squirting. The upper squirters 13 are directed toward the outlet of the drum cooler, and the lower squirters 14 are directed at an angle toward the dark surface of the screen. The lintel on the outer surface has annular protrusions 15. A screen 17 is hung on the lintel with, for example, hook-shaped kerchiefs 16. It, together with kerchiefs, can be rotated relative to the lintel and attached to the annular projections at a given angle to the vertical.

At the front end of the water jacket there is a water outlet hole 18 on top.

The device works as follows.

A stream of slag melt flows down into the hydro-grooves 1 of the air-air porizer, where it is penetrated by streams of water and porous. Moving down the gutter, porous

The slag mass is encountered with the stream of air leaving the air nozzle 2, dispersed and carried by it inside the acceleration chamber 3.

In the acceleration chamber, porous, still plastic particles of slag are accelerated by the air flow and are ejected from it inside the housing of the drum cooler 10. There they hit the working surface of the screen 17, oriented to the vertical, for example, at an angle of 30-45 ° C, reunited Signs of mass that are at the same or slightly smaller angle to the vertical are painted on the inner surface of the casing of the drum cooler.

Due to the presence of an acute angle between the acceleration chamber and the drum cooler and the tilted position of the consoles, there is enough clearance between the lower edge of the screen and the inner surface of the drum cooler to contain a significant layer of porous mass in it.

In the process of passing the slag particles through the acceleration chamber and throwing them onto the screen, these structural elements are intensely heated. To prevent warping and burnout, they are subjected to water cooling.

The acceleration chamber is cooled with water, which flows through the inlet nozzle 6 into the lower cavity of the water jacket 4, leaves it through one tubular console 11, passes through

jumper 12 and through another tubular 40 in height at the bottom of the cavity, the console is connected to the upper cavity of the water jacket. From it, it goes through the outlet nozzle 7 and enters the circulating water supply system of the cooling water. A certain predetermined amount of cooling water is ejected through the lower and upper rows sprinkled.

Water from the bottom row splashed on the back surface of the screen and intensively cools it, mainly due to evaporation. This is a pre-. rotates overheating and, as a result, warping and burnout of the screen.

Water from the top row sprinkles coals the porous slag mass. This allows to reduce the specific consumption of water for the porisation of the slag melt to an optimum, which ensures

The production of gravel-like pshak pumice with a minimum saturation density, in addition, allows you to enter, by passing the air / water porizer, into the drum cooler the additional amount of water needed for the required cooling of gravel-like slag pumice and, thereby, to ensure the normal operation of conveyors and sorting equipment.

Through the vapor outlet 18, air and 5 water vapors accumulate there from the top of the water jacket. Along the way, a certain amount of water flows out, which is immediately sprayed by the air stream leaving the acceleration chamber, and accumulates with slag particles on the screen.

The possibility of rearranging the screen at different angles to the vertical allows one to regulate the process of reuniting slag particles and, thus, the quality of slag pumice.
