The carrier equipment of the green brick in the secondary dryer is a drying car. The bricks are stacked on the drying car by the racking system. After drying, the drying car is unloaded by the lowering system, and then the bricks are stacked on the kiln car by the racking system. This operation adopts a single layer drying method, which is suitable for raw materials with high moisture content, because each green brick is fully dried, and the drying efficiency is high.
The drying medium is generally provided by the waste heat of the roasting kiln and is supplemented by the burner when the heat is insufficient. The drying room is equipped with a hot air supply system, a moisture exhaust system and a temperature and humidity monitoring system. By monitoring and adjusting the system, the supply air temperature and air volume can be controlled to ensure the drying quality of the bricks.
The structure of the secondary dryer is a multi-channel brick-concrete structure or a multi-channel frame structure without partition walls to adapt to different drying requirements.
- Q: The working principle of belt dryer
- For the material temperature does not exceed 60oC requirements, can be used about 80oC dry gas. Multi-stage combination can better play the performance of belt dryer, and dry more uniform.
- Q: What are the basic types of common drying equipment?
- (4) hollow paddle dryer (leaf dryer) hollow paddle dry dryer, also known as leaf dryer, mainly by the jacket with the W-shaped shell and two hollow blade shaft and transmission components. A hollow blade is arranged on the shaft and a rotary joint with a heat medium inlet is provided at the shaft end. The heat required to dry the moisture is conducted to the material by the inner wall of the W-shaped groove with the jacket and the hollow leaf wall.
- Q: What are the common drying methods?
- Is the use of moisture to remove gas, liquid, solid material in a small amount of water, due to moisture dehumidifier dehumidification capacity is limited, only used to remove trace moisture in the material, so the production of very little.
- Q: How to solve the dryer a series of failures
- The dew point reading can help to find some problems, so the dry air dew point value should be monitored throughout the drying process. Dryer normal operation of the dew point reading should be 20of ~ 50of within a straight line, of course, the replacement of the dryer caused by small fluctuations are normal. If the dryer is operating normally, the dew point at the dry air inlet should be at least 30of lower than the dew point at the return air outlet.
- Q: How to choose the right drying equipment and drying technology
- For non-hygroscopic materials, the moisture present in any environment remains on the surface and becomes "surface moisture" and is easily removed.
- 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: 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: Frozen sublimation drying equipment which consists of several systems
- the control system: the control system consists of a variety of monitoring the original, an umbrella device, instrumentation and other components, a higher degree of automation control system can be set by the freeze-drying process automatically operate, while the vacuum, heating plate temperature and cooling System monitoring and alarm, record all kinds of data.
- Q: What are the characteristics of the drum dryer?
- conventional direct heating rotary drum dryer conventional direct heating rotary drum dryer in the dry material and hot air Direct contact with the way of convection heat drying in accordance with the direction of flow between the hot air and material, divided into parallel and countercurrent.
- Q: What is a combination of drying equipment?
- Combination drying equipment is a combination of two or more dry forms, the main material, mainly in series, that is, when the material has been through the drying equipment, two or more drying equipment, combined dry mainly to meet a The need for a drying process.
