Abstract
The utility model relates to a double-spiral slag cooler. The double-spiral slag cooler comprises a slag cooler body, a slag inlet, a double-roller tooth roller crushing device, a slag particle tundish, a double-spiral rotating disk device, a rotating shaft, a scraper, a hot air and fine slag particle outlet and the like. The double-roller tooth roller crushing device comprises detachable roller teeth, and cooling mediums are fed in the walls of the two rollers. When the double-spiral slag cooler works, the two roller teeth rotate inwards in the opposite directions, and slag particles are squeezed to be broken and cooled through engagement of the two roller teeth. The double-spiral rotating disk device is composed of a spiral rotating disk 1 and a spiral rotating disk 2. The start points of the two spiral rotating disks are different, and the rotating disks incline inwards to be concave. A cold water pipe is arranged at the bottom of the spiral rotating disk on each layer and annularly arranged at the bottom of the spiral rotating disk in an encircling mode. A vent port is formed in the position, as high as the double spiral rotating disks, on the furnace wall. The cooling area is increased, and combustible particles in hot air and slag can be recycled. The slag cooler has the advantages of fast cooling slag and being low in power consumption and effectively avoids the problems of slag blocking and resource waste.

Described double helix rotary turnplate below is all provided with cold water pipes, and pipeline is looped around spiral rotating rotating disk below ringwise.
The bottom of the helix swiveling plate axle in described double helix rotary turnplate device is provided with scraper plate, rotates with turning cylinder.
Described slag cooler bottom is provided with place's sector open.
On slag cooler wall described and helix swiveling plate equal height, be provided with cooling air port.
Gear hobbing on described twin-roll discaling roll breaker cylinder is detachable gear hobbing, and is connected with cooling medium between drum shaft and gear hobbing.
beneficial effect:
1. the twin-roll discaling roll device of double-screw type slag cooler is in the opposite direction, discaling roll all rotates to the near direction of another cylinder, fall on discaling roll by the slag particle of slag particle import, through the engagement extruding of two discaling rolls, make slag particle again carry out fragmentation, and the cooling medium of cylinder inside carries out cooling for the first time to slag particle, the stifled slag of slag particle great Yi and the poor defect of cooling effect are eliminated.
2. the discaling roll in twin-roll discaling roll device is demountable structure, has eliminated because of the slag particle defect that causes whole machine not move of wearing and tearing.
3. slag particle is fallen on double helix rotating disc by slag particle tundish after the granulation of twin-roll discaling roll device is cooling, is undertaken coolingly by the rotation of rotating disc and the cooling water pipe of rotating disk below, is that slag particle obtains cooling fully fast.Because double helix rotating disc has increased the heat exchange area of slag particle, make slag particle cooling more fast fully.
4. the cooling air port on slag cooler wall is again cooling to slag particle, and the molecule that can again burn in slag particle is reclaimed, and the energy is fully used.
5. the hot water after cooling slag particle can, directly as the heating raw of boiler, have been eliminated water resource waste.
