Mobile kiln/Low cost/Diverse process layout/No kiln car/high efficiency of thermal system

Brief overview

The roasting process system designed with reverse thinking method, in which the green body material does not move and the kiln body moves, can form a variety of process layouts, which can adapt to a variety of raw materials, a variety of products and corresponding processes. The kiln body of the mobile kiln is movable, the fire moves synchronously with the kiln body, and the green body material does not move. When the fire and the green body material move relative to each other, it is the same as the "car entry" principle of ordinary tunnel kiln.

Type

It can be divided into circular tunnel kiln and reciprocating tunnel kiln.

1.circular tunnel kiln

2.reciprocating tunnel kiln

Process

The core of this technology is to place the green body material between the kiln bottom and the front track by moving the kiln body on the track, and gradually complete the drying, preheating, roasting and cooling processes during the kiln body moving forward, and then ship the finished product out from the open kiln bottom.

Advantages

1. Low cost;

no kiln car, drying car and kiln car operating equipment are required;

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

the mobile kiln wall is made of aluminum silicate refractory fiber stacking, which has good insulation effect;

3. Automation and intelligence, less labor;

the mobile kiln has no kiln car and kiln car operating equipment, uses less manpower, and can be operated automatically;

4. No kiln car maintenance, resistant to cold and heat shock;

a. The kiln body can expand and contract freely during thermal expansion and contraction, and the kiln wall is made of aluminum silicate refractory fiber stacking, which not only reduces the weight of the kiln body and the thermal expansion and contraction stress of the kiln body, but also does not have kiln cracks;

b. The thickened kiln wall with redundant design can withstand longer airflow scouring and thus increase the service life;

c. There is no kiln car, so there is no kiln car maintenance. This alone can save a lot of maintenance costs every year.

5. Good controllability and low failure rate of the traveling mechanism;

The highly reliable array kiln drive mechanism has a simple and reliable structure, variable frequency speed regulation, flexible start and stop, reversible forward and backward movement, and accurate automatic positioning of the kiln body.

6. Simple equipment layout, safe and reliable;

The kiln drive equipment, kiln door lifting equipment, fan, traveling mechanism, etc. not only meet the process needs, but also pay special attention to humanized design, easy and barrier-free operation during use, comfortable and easy operation during maintenance, and reliable protection to ensure safety.

Application

The mobile kiln has been gradually promoted and applied in the fields of new material calcination, building materials, and ceramics with its low investment, convenient use, and high degree of automation, and has achieved good economic benefits.
