Multilayer roller-way in the present embodiment dry kiln uses six layers of roller-way, has following superior function after tested：
1, dry heat utilization efficiency is high, obvious energy conservation.
The drying heat consumption of six layers of roller way drying kiln can reach 1,250~1,500kcal/kg water, and domestic conventional drying heat
Consumption is 2, and 500~3,000kcal/kg water or so, two compare, and the heat utilization efficiency of six layers of roller way drying kiln about improves 50% left side
It is right.Main cause is that hot air circulation heat utilization efficiency is high, and rate of drying is fast, hydrofuge amount is few and discharge temperature is low, kiln body heat dissipation area
Several aspects such as small.
2, arid cycle is short, high-efficient.
Six layers of roller way drying kiln dry period can be controlled in 30~40 minutes when dry 600*600mm polished bricks, and state
The period of interior conventional drying commonly reaches 60~70 minutes, and six layers of dry efficiency can be improved 45% or more.
3, seasoning defect drying defect rate is low.
Since the adobe speed of service in six layers of roller way drying kiln is relatively slow, (linear velocity of adobe is single layer roller way drying kiln
1/6), be heated evenly, almost without mechanical damage, whens dry 600*600mm polished bricks dry qualification rate up to 99.5% or more,
And domestic conventional drying qualification rate is generally below 98.5%.
4, conversion products are flexible, and can fast and stable.
The dry kiln sets a combustor and circulating fan system in 3.5M long/adjusting range, and it is independent totally to set several sets
Dehumidification system, not only the temperature of every section can automatically adjust in this way, and every section hot wind humidity can also be flexible by hydrofuge amount
It adjusts.Fast and stable is required to have apparent advantage when this respect is for ceramics factory's frequent transitions product.
5, production stability is good.
The heating system of the drier settable combustor and circulating fan independent control, and it is equipped with independent hydrofuge system
System only uses the cooling residual heat of part burning kiln, and burning kiln and dry kiln influence each other less, in production process stability compared with
It is good.
6, ambient enviroment is good, and equipment life is long.
Six layers of roller way drying kiln mainly utilize combustor and a small amount of burning kiln cooling section waste heat wind is heat source, corrosion-free,
And it is dry itself to recycle based on hot and humid gas, positive pressure is up to 5Pa in dry kiln, hot gas escape it is less outside kiln, in drier
Maximum temperature is no more than 180 DEG C.
And normal drying kiln generally (need to can reach high temperature containing certain humidity using the smoke discharging residual heat of burning kiln in kiln hood
High humidity reduces the possibility for splitting brick), back segment cooling residual heat reduces the temperature difference by high positive pressure (20Pa or more), (up to high temperature
250 DEG C) hot gas do not recycle " slow bored dry " and reaches drying effect.It is such the result is that entire workshop is full of the flue gas for nose of choking, it is dry
Kiln ambient temperature is higher, and the sulphur in flue gas can also corrode rapidly kiln frame or even house frame steel, severe operational environment.
7, different colorful products can be dried simultaneously.
Six layers of roller way drying kiln into settable two elevators of kiln, respectively correspond 3 layers and lower 3 layers of supply adobe, side
Just the different pattern adobes of like products size are distinguished by ceramics factory, change the line of production flexibly, improve utilization rate of equipment and installations.
