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 order to overcome the above shortcomings. I plant in accordance with foreign advanced technology design and development through the flow box-type dryer, the working principle shown in Figure:
- Q: The working principle of belt dryer
- Drying process is a hot air flow through the material layer, complete the process of heat and mass transfer, the upper cavity connected by the duct and the fan inlet. Most of the gas circulation, part of the lower temperature of the larger moisture content of the gas as exhaust gas through the drainage tube, regulating valve, drain fan discharge. The next cycle of the unit, the fan out of the wind into the upper cavity, down through the heat exchanger heating, through the material layer into the lower chamber, the lower chamber by the side duct and return air duct connected to the fan, most of the gas circulation, Part of the discharge. Up and down the cycle unit according to user needs can be flexible equipment, the number of units can also be selected according to need.
- 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.
- Q: What are the common types of dryers?
- The tank flows into the chute of the drum dryer, and the drying drum is rotated at the specified speed by the drive.
- Q: What are the common drying methods?
- heating and drying method
- Q: How to solve the dryer a series of failures
- If the dew point reading is normal after the dry machine is replaced, the dew point rises rapidly after the end of the drying cycle of the dryer, indicating that the ambient air may enter the closed gas path, causing the dryer to absorb prematurely. Another possibility is that the dryer is not completely regenerated or contaminated. If the dew point reading and reflow air dew point readings are close, it indicates that the regenerative gas path is completely failing or the desiccant is seriously polluted.
- Q: What are the types of drying equipment?
- According to the operating pressure, the dryer is divided into two types of atmospheric pressure dryer and vacuum dryer. Microwave flour sterilization drying equipment can reduce the moisture partial pressure of the space and accelerate the drying process, and can reduce the wet boiling point and material Drying temperature, steam is not easy to leak, so the vacuum dryer for dry heat-sensitive, easy oxidation, explosive and toxic materials and wet steam needs to be recycled occasions.
- Q: Frozen sublimation drying equipment which consists of several systems
- refrigeration system: refrigeration unit and freeze-drying chamber, the condenser inside the evaporator and other components. Chillers can be independent of two sets, that is, a set for the freeze-drying room, a set for the condenser, can also be combined with a set of freezer.
- Q: What are the characteristics of the drum dryer?
- direct heating type Rotary drum dryer This kind of dryer is directly connected with the dry material, mainly by convection heat transfer, the most widely used.It is divided into conventional direct heating rotary drum dryer, Rotary drum dryer and ventilated tube rotary drum dryer
- Q: What is a combination of drying equipment?
- As we all know, each dryer there are some shortcomings, through the same or two or more models in series, using their own advantages, often play a single device can not achieve the purpose.
