移動式トンネル窯

移動式トンネル窯の窯本体は二重環状軌道上を走行します, with drying section, 予熱部, roasting section, insulation section, and cooling section arranged from front to back. When the kiln body moves forward, the bricks brought in from the front door of the kiln will be exposed to the outside of the kiln tail door after completing the entire process of drying, preheating, and firing with the movement of the kiln body.

Mobile tunnel kilns can flexibly choose suitable process systems based on market, capital, 原材料, 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. したがって, it is not recommended to use it widely and should only be used in special circumstances.

2. 低エネルギー消費, 熱工学システムの高効率, 優れた断熱効果, 高い廃熱利用率

移動式トンネルキルンの壁にはケイ酸アルミニウム耐火繊維が積層されています, 優れた断熱効果があります. 実験生産ラインの実習中, 石炭と空気の供給を停止した後、 48 時間, 石炭と空気を再供給した後も、窯は通常どおり焙煎できます。. 使用中で, 窯壁焙煎部の外表面温度はあくまで 42 ち）

移動式トンネルキルンの熱システム内, レンガの焼成によって放出されるすべての熱は、燃焼と乾燥の目的で窯に入る空気によって焙煎および乾燥セクションに送られます。. で 2007, 試射中に, エネルギー消費量はわずかでした 240-340 kcal/kg.

3. 雇用が少ない

生産ラインでは約 30-40 人々:

2 給餌用のブルドーザー, 4 混ぜたり粉砕したりする人たち, 2 レンガづくりの人たち, 3-6 パレタイジングの人たち, 8-15 乾燥と焙煎をする人たち, 3 レンガ生産のための人々, 6 人間と機械の修理のための人々, と 2 レンガづくりの人たち

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, 交通機関, aging, billet making, drying, 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

a. The kiln body can freely expand and contract during thermal expansion and contraction. キルン壁にはケイ酸アルミニウム耐火繊維が積層されています, 窯本体の重量と熱膨張収縮応力を軽減するだけでなく、, だけでなく、炉の亀裂も回避します;

b. 冗長設計により厚くなったキルン壁は、長期間の気流侵食に耐えることができます。, これにより耐用年数が向上し、オーバーホールサイクルが延長されます。;

c. 窯車なし, 窯車のメンテナンスがなくなる, これだけで約 200000 年間のメンテナンス費用は人民元.
