Description
Technical Field
The utility model belongs to the technical field of the metallurgy, especially, relate to a cold quick-witted partition wall of ring that forced air cooling and water-cooling combined together.
Background
At present, in the metallurgical industry, along with the maximization of a blast furnace and the improvement of the production automation degree, the quality requirement on the blast furnace charge is higher and higher, pellets become indispensable components in the current smelting charge due to the unique metallurgical performance of the pellets, a ring cooling machine is one of three main machines for producing the pellets of a rotary kiln of a chain grate machine, the main function is to cool the high-temperature pellets discharged by the rotary kiln so as to be safely conveyed and stored, meanwhile, heat is recovered from the high-temperature pellets for the front-stage process, the running state of the ring cooling machine not only directly influences the production capacity of a chain-return-ring system and the quality of the pellets, but also has important influence on the energy consumption and the running cost of the whole system.
The cooling method of the ring cooling machine is generally divided into four sections, each section is separated by a partition wall, the original partition wall of the ring cooling machine is an air-cooled partition wall which is of a box-shaped structure, anchoring parts are welded on the surface, and the outer layer is made of casting materials.
Chinese patent specification discloses "an improved pellet ring cooling machine partition wall" (No. CN204987893U), and its technical scheme is that a plurality of wind deflectors are installed on the upper and lower inner walls of the air box in a crossed manner, the wind deflectors divide the internal cavity of the air box into a plurality of zigzag-structured air channels, one end of each air channel is communicated with an air inlet, and the other end is communicated with an air outlet, so that the partition air box plate and cooling air can fully perform heat exchange, and the cooling effect can be enhanced. However, the cooling method only relies on 'wind' as a cooling medium, and the cooling effect is not fundamentally improved.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that exists, the utility model provides a cold quick-witted partition wall of ring that forced air cooling and water-cooling combined together, this cold quick-witted partition wall of ring combines together forced air cooling and water-cooling, has improved the cooling effect greatly, has practiced thrift manufacturing cost, has ensured safety in production, has improved product quality.
In order to achieve the above object, the present invention adopts the following scheme, including:
the air cooling wall comprises a box-shaped wall body of a steel structure, wherein an air inlet is formed in one end of the box-shaped wall body, and an air outlet is formed in the other end of the box-shaped wall body; the annular cooler partition wall further comprises a water-cooling beam and a high-alumina brick layer located between the top surface of the water-cooling beam and the bottom surface of the box-shaped wall body.
The water-cooling beam is of a box-type structure, one end of the water-cooling beam is connected with the water inlet pipe, and the other end of the water-cooling beam is connected with the water outlet pipe.
The water inlet pipe of the water-cooling beam is close to the bottom of the water-cooling beam, and the water outlet pipe of the water-cooling beam is close to the upper portion of the water-cooling beam.
The water-cooling beam is of a steel structure.
And high-strength refractory materials are poured on the outer surfaces of the air cooling wall and the water cooling beam.
The utility model discloses combine together forced air cooling and water-cooling, improved the cooling effect greatly, practiced thrift manufacturing cost, ensured safety in production, improved product quality.

The water-cooling beam is of a box-type structure, one end of the water-cooling beam is connected with a water inlet pipe 6, and the other end of the water-cooling beam is connected with a water outlet pipe 7.
The water inlet pipe of the water-cooling beam is close to the bottom of the water-cooling beam, and the water outlet pipe of the water-cooling beam is close to the upper portion of the water-cooling beam.
The water-cooling beam is of a steel structure.
And high-strength refractory materials are poured on the outer surfaces of the air cooling wall and the water cooling beam.
The utility model discloses in, except that the air-cooled wall cools off high temperature pelletizing, the heat of high temperature pelletizing can also conduct rapidly for the high alumina brick layer, and the water-cooling roof beam not only plays the supporting role to the high alumina brick layer, carries out quick effectual cooling to the high alumina brick layer again simultaneously.
The utility model discloses combine together forced air cooling and water-cooling, improved the cooling effect greatly, practiced thrift manufacturing cost, ensured safety in production, improved product quality.
