Tunnel roasting kiln can be divided into straight tunnel kiln (with kiln car) and mobile rotary tunnel kiln (without kiln car). Straight tunnel kilns can be further divided into masonry tunnel kilns and prefabricated tunnel kilns in terms of construction methods. The mobile rotary tunnel kiln belongs to the assembled tunnel kiln.
Straight Tunnel Kiln:
(1) Main products: sintered bricks, common bricks, porous bricks, hollow bricks/blocks, roof tiles, hollow wall panels.
(2) According to the different output, the inner width of the tunnel kiln is divided into the following types:
① the inner width is 3.6 and 3.7 meters, suitable for daily output of 150,000-200,000 blocks, and annual output of 50-66 million (common bricks)
② the inner width is 4.6 and 4.8 meters, suitable for daily output of 210,000-250,000 blocks, and annual output of 69-82 million (common bricks)
③ the inner width is 5.4 and 5.6 meters, suitable for daily production of 260,000-300,000 pieces, and annual output of 85-100 million (common bricks)
④ the inner width is 6.9 and 7.2 meters, suitable for daily output of 310,000-400,000 blocks, and annual output of 102-132 million (common bricks)
⑤ the inner width is 9.2 and 9.4 meters, suitable for daily output of 600,000-620,000 pieces, and annual output of 165-200 million (common bricks)
(3) Kiln Body Structure
Assembly Type Tunnel Kiln
The kiln wall and kiln roof are factory processed into different units and spliced on site. The structural form of kiln wall is non-sintered clay refractory concrete wall panel + high-strength heat-resistant stainless-steel component + refractory fiber module + steel structure + enclosure pressure steel plate. The structural form often used on the kiln roof: light mullite plate + high-strength heat-resistant stainless-steel components + aluminum silicate refractory fiber blanket + steel structure.
(4) Firing temperature: 950-1050℃
(5) Firing cycle: 26-40h
(6) Length of tunnel kiln: 110-170m
(7) Length and size of kiln car: It is determined according to the size of the billet stack and the internal and external combustion method. The length and size of the commonly used kiln car are: 3600mm, 3900mm, 4100mm, 4200mm, 4350mm, 4800mm, etc.
(8) Firing method: all internal combustion roasting; all external combustion roasting; combined internal and external combustion roasting.
(9) The roasting kiln is often equipped with a smoke exhaust system, a combustion system, a waste heat system, a backburning system, a cooling system, and a bottom pressure balance system. Each system consists of fans, pipes and regulating valves. The kiln has a large section, high output, small temperature difference between sections, and good thermal insulation performance. Computer automatic monitoring and control system to ensure the stability of thermal parameters and roasting quality.
- Q:What is the best drying equipment?
- In the traditional horizontal fan-type dryer, the air flow only in the material surface flow, the drawback is the low heat transfer coefficient, poor heat utilization, material drying time is long.
- Q:Frozen sublimation drying equipment which consists of several systems
- the heating system: for heating the freeze-drying room shelf, to promote the material within the ice sublimation, direct and indirect heating in two ways, direct heating is the direct heating in the box inside the shelf, indirect heating is the use of electricity Or other heat source heat transfer medium, and then pass it into the shelf.
- Q:How to choose the right drying equipment and drying technology
- Hygroscopic materials can absorb moisture from the surrounding environment, non-hygroscopic materials can not absorb moisture from the environment.
- Q:What are the common types of dryers?
- Roller scraper dryer is through the rotation of the cylinder, in a heat conduction way, will be attached to the outer wall of the cylinder liquid material or ribbon material, dry a continuous operation of equipment to be dry treatment of liquid from the high
- Q:The working principle of belt dryer
- For dehydrated vegetables, the general use of three devices in series, the formation of early dry section, the middle section and the final section. In the early dry section, due to high water content of materials. Poor ventilation, so the use of a smaller thickness of the shop material, faster running speed and higher drying temperature. In the early dry section, the dry gas temperature can be as high as 120oC or more. The length of the material in the final section is 3-6 times of the initial dry section, and the thickness of the material is 2-4 times of the initial dry section.
- Q:What is a combination of drying equipment?
- Recently, a combination of different drying methods and different drying principles has been widely used, and a drying device capable of exerting their own advantages and making up their respective shortcomings.
- Q:What are the characteristics of the drum dryer?
- The main body of the rotary drum dryer is a slightly tilted and rotatable drum, and the wet material is fed from one end thereof and passes through the inside of the drum and is dried in contact with the hot air or the heated wall in the cylinder. , Chemical industry, metallurgy, building materials and other industries have a wide range of applications. Rotary drum drying and other drying equipment compared to the production capacity, continuous operation and simple structure, easy operation and less trouble, low maintenance costs
- Q:The development prospects of the dryer
- Compared with the adsorption dryer, the cold and dry machine is relatively energy efficient in its applicable field. But the cold and dry machine in the small load operation also exists "big horse car" energy waste phenomenon. People want the cold and dry power consumption can follow the load changes and adjust themselves to achieve the best energy saving effect,
- Q:What are the types of drying equipment?
- According to the heating method, the dryer is divided into convection, conduction, radiation, dielectric and other types. Convection dryer, also known as direct dryer, is the use of hot dry media and wet material in direct contact with convection way to transfer heat, and the generated steam away; Conductive dryer also known as indirect dryer, which uses conduction The heat is transferred from the heat source through the metal wall to the wet material, and the resulting wet steam can be removed by means of reduced pressure suction, passing a small amount of purge gas or condensing it on a separately provided low
- Q:What are the basic types of common drying equipment?
- Common types of common drying equipment (1) slime dryer slime dryer its working principle is as follows: moisture content of 25 to 40% of the wet slime first after a special material scrambling device after the break up by the belt The machine is transported to the feeder, and then the wet slime is fed into the drying drum by the feeder. The slime is spread under the drying drum, and the slag is evenly dispersed and fully communicated with the hot air to reach the heat transfer, Mass transfer of purpose.
