Bentonite dryer is mainly used for the drying of various types of clay mud, such as bentonite, kaolin, aluminum, and iron clay, and solves some problems of sticking, crushing, and drying. Therefore, Jiutian Machinery successfully launched a bentonite dryer according to this development direction.
The bentonite dryer can use a variety of fuels such as coal, oil, gas, etc. At present, the boiling furnace is favored by users due to its convenient operation, energy saving, environmental protection, and easy purchase of raw materials. Some manufacturers also choose natural gas or coal gas generators for conversion, and the gas undergoes secondary combustion to achieve the drying effect. It is an environmentally friendly and energy-saving product that replaces traditional drying equipment.
The bentonite drying system is mainly composed of a hot air stove, belt feeder, drum dryer, belt discharger, induced draft fan, cyclone dust collector, bag filter (or wet dust collector), and operation control system.
The equipment adopts the downstream drying process, and its working principle is as follows: The first is the guide area, where the bentonite enters this area and quickly evaporates water in contact with the high-temperature hot air, and the material is guided to the next working area under the movement of the guide plate with a large lead angle; The second is the copying area, where the bentonite is picked up by the copying board to form a material curtain. At this time, the material is in full contact with the hot air, and the water in the mineral slag quickly evaporates and strips into water vapor, and the water vapor is then sucked away by the induced draft fan. So as to achieve the purpose of drying; the bentonite is dried in this area to a loose state with moisture less than 5% (or lower). After heat exchange, the material reaches the required moisture state and enters the final discharging zone; The third is discharging In this zone, the drum does not have a copy board, and the material rolls and slides to the discharge port in this zone to complete the entire drying process.
1. The fixed-speed quantitative feeder is used to solve the uniformity of feeding and drying in the dryer and overcome the previous problems of intermittent feeding, material blocking, and large instantaneous material volume. It is the prerequisite for improving the evaporation intensity.
2. Design a unique buffer silo and feeding mechanism to overcome the problem of intermittent feeding or fluctuations caused by uneven feeding;
3. Optimizing the design of the internal structure of the dryer to maximize the heat exchange area between the material and the hot air is the basis for improving the evaporation intensity.
4. Continuously optimize the design of the internal structure of the drum and the lifting plate, and finally, finalize it into the unique structure of the internal lifting plate of the drum and the mixed interval layout of different functions. The full section of the drum has a uniform "material curtain" without dead angles and gaps, and maximize Increase the heat exchange area between bentonite and hot air so that the moisture in the bentonite will quickly heat up and vaporize, and be taken away by the hot air.
5. Original patented layered drying technology of rotary drum dryer. According to the different rules of heating speed and moving speed of granule materials of different sizes in the drum, several groups of layered drying devices are set up to control the power of small granule materials due to excessive drying and the phenomenon of uneven drying of large granule materials due to different heating inside and outside, so as to ensure the uniformity of drying.
6. Reasonable selection of hot blast stove type, optimization of its internal structure design and masonry quality, reducing air leakage rate, lowering the oxygen content in the hot blast to less than 5%, the 700-1100ºC arbitrary process requires temperature points to be adjusted at will, providing a stable heat source for the dryer, is a reliable guarantee for the high-strength operation of the bentonite dryer.
7. Optimized configuration of gravity sedimentation + cyclone dust collector + wet/bag dust collector three-stage dust collection and dust removal equipment, dust concentration <50mg/Nm3, to ensure that the exhaust gas meets the emission standard.
8. It solves the problem that water vapor returns to the material after the temperature of the system decreases during the same direction movement caused by the downstream dehumidification of the traditional dryer, improves the drying efficiency, and achieves the purpose of deep dehydration.
9. The dryer adopts fish scales or labyrinth, expandable graphite packing type mechanical seal dual sealing mode, to ensure the safe operation of the dryer system with closed oxygen.
