мобильная туннельная печь

Корпус мобильной туннельной печи движется по двойным кольцевым направляющим., с сушильной секцией, секция предварительного нагрева, секция обжарки, секция изоляции, и секция охлаждения расположены спереди назад. Когда корпус печи движется вперед, кирпичи, принесенные через переднюю дверцу печи, после завершения всего процесса сушки окажутся снаружи задней дверцы печи., предварительный нагрев, и обжиг при движении корпуса печи.

Mobile tunnel kilns can flexibly choose suitable process systems based on market, capital, сырье, geography, transportation and other conditions.

1. One time code firing, integrated with drying kiln and roasting kiln:

The biggest feature of this process is that it requires minimal labor and low energy consumption, but it requires the use of higher wet billet strength and high extrusion pressure requirements for the brick machine.

2. One and a half yard firing, integrated with drying and baking kilns;

This process can achieve a higher total output compared to brick machines with the same kiln investment and lower extrusion pressure, but it requires a higher process system, making it difficult to code the billet, requiring more labor, and requiring a relatively high level of management.

3. Secondary code firing, separate drying and roasting kilns:

High production, but high energy consumption, large logistics tasks, and high labor costs. Следовательно, it is not recommended to use it widely and should only be used in special circumstances.

2. Low energy consumption, high efficiency of thermal engineering systems, good insulation effect, high waste heat utilization rate

The wall of the mobile tunnel kiln is stacked with aluminum silicate refractory fibers, which has a good insulation effect. In the practice of the experimental production line, after stopping coal and air supply for 48 часы, the kiln can still be roasted normally after re feeding coal and air supply. In use, the outer surface temperature of the kiln wall roasting section is only 42 C ˚）

В тепловой системе мобильной туннельной печи, все тепло, выделяемое при обжиге кирпича, передается в секции обжига и сушки воздухом, поступающим в печь, для сжигания и сушки.. В 2007, во время пробных стрельб, потребление энергии было всего 240-340 ккал/кг.

3. Низкая занятость

На производственной линии работает около 30-40 люди:

2 бульдозеры для кормления, 4 люди для смешивания и измельчения, 2 люди для изготовления кирпича, 3-6 люди для паллетирования, 8-15 люди для сушки и обжарки, 3 люди для производства кирпича, 6 люди для человеко-машинного ремонта, и 2 люди для изготовления кирпича

4. Small footprint

Except for the raw material storage yard, the production line only requires about 27 acres of land.

5. Smooth logistics and low labor intensity

In the production of a brick factory with an annual output of 50 million pieces, the daily logistics volume between various processes such as raw material preparation, транспорт, старение, billet making, сушка, and firing is about 430T × (5-8 times), most of the manpower in ordinary rotary kilns is consumed here, and the labor intensity is high, and the working environment is harsh.

The production line of the mobile tunnel kiln process system has a mechanized and automatic logistics operation. Workers only need to pick up and stack bricks from the billet conveyor belt, which is quite easy compared to the loading and unloading of the rotary kiln. Especially, the working environment is bright and open, neither dirty nor hot.

6. No kiln car maintenance, long maintenance cycle for cold and hot shock resistance of kilns

а. The kiln body can freely expand and contract during thermal expansion and contraction. The kiln wall is stacked with aluminum silicate refractory fibers, which not only reduces the weight and thermal expansion and contraction stress of the kiln body, but also avoids furnace cracks;

б. The thickened kiln wall with redundant design can withstand longer periods of airflow erosion, thereby improving its service life and prolonging the overhaul cycle;

c. Without kiln cars, there would be no kiln car maintenance, and this alone can save about 200000 yuan in maintenance costs annually.
