Dual patents of three-drum dryer;
Patent number: ZL200820035965.4
Patent number: ZL2008300298 15.8
Use:
Used for drying slag, sand, coal, fly ash, iron powder, ore, quartz sand and other materials.
Features:
1, high technical content, self-insulation of the cylinder, high thermal efficiency of 80% (thermal efficiency of single-cylinder dryer is only 35%), saving coal by 68% compared with single-cylinder drying, and increasing production by 100%.
2. It is 60% shorter than the single-cylinder dryer, which is beneficial to process layout. Reduce the building area of the factory building and save about 40% of the project investment. Covers an area of about 20m2.
3. Heat-resistant and wear-resistant alloy steel plate is adopted, which is four times more wear-resistant than ordinary steel plate. Long service life and convenient maintenance.
4. The thermal efficiency is high, the outer cylinder temperature is lower than 60℃ (the outer cylinder temperature of single cylinder dryer is as high as 150℃), the outlet temperature is low, and the discharge temperature is lower than 60℃.
5, the outlet temperature is low, which is beneficial to the long service life of the dust removal equipment and can be directly matched with the bellows pulse dust collector ">; Bag filter.
6. Civil construction investment is reduced by about 50%, and power consumption is reduced by 60%.
7. Don't need the big and small gears to rotate, and use the idler to rotate.
8. The hot blast stove can be used together with a boiling furnace, a coal injection furnace, a hand-fired furnace, an oil furnace and a gas furnace, and can dry lump, granular and powdery materials below 20mm.
9. Output per hour: 5-1010/515-20 20-25 25-30 30-40 40-50 50-60 60-70 70-80.
The biggest advantage of the three-drum dryer is its high heat utilization rate and good drying effect. The advantage of vertical dryer is that it occupies a small area, but it is easy to block materials and the initial moisture is difficult to control. The problem of low maintenance rate of three-cylinder dryer.
