Description
Technical field
The present invention relates to a kind of air distribution plate large-amplitude vibration fluid-bed separator, be particularly useful for the coal dry separation, also be applicable to the dry separation of other mineral, belong to mineral processing equipment technical field.
Background technology
In the art, the fluid bed coal preparation technology is a kind of emerging dry coal preparation technology, fluid bed dry coal preparation technology can better satisfy the requirement of the regional coal separation of NORTHWEST CHINA portion drought and water shortage, existing fluid bed dry coal preparation technology medium solid granularity is thicker, cause to form high-quality fluidized state, and, because the generation of bubble causes medium solid can not keep stable fluidized state etc., therefore how eliminating bubble in vibration processes is the key issue that now faces to the influence of assorting room.
Summary of the invention
Technical problem: the objective of the invention is to overcome the weak point in the prior art, a kind of simple in structure, stable air distribution plate large-amplitude vibration fluid-bed separator is provided.
Technical scheme: air distribution plate large-amplitude vibration fluid-bed separator of the present invention, comprise casing, the bottom of casing is provided with to airduct, and the top of airduct is provided with the air distribution plate that matches with cabinet wall, the connecting rod that is connected as a single entity with air distribution plate bottom the middle part of air distribution plate is provided with; Described air distribution plate is made up of the two-layer filter cloth that is covered with the steel plate of passage and is clipped between the two-layered steel plates; The outside of described casing is provided with plate platform, plate platform is provided with fixed bar, hinged securement has drive link on the fixed bar, one end of drive link links to each other with the top of connecting rod, the other end of drive link is connected with power rail, be connected with eccentric wheel on the power rail, eccentric wheel is provided with and can changes a plurality of eccentric connecting hole that cloth divides plate amplitude size.
The described airduct air outlet of giving is provided with radome fairing; Described casing is square or cylindrical; Have in described a plurality of eccentric connecting hole and can change cloth and divide the plate amplitude to reach the eccentric connecting hole of 30cm.
Beneficial effect: the vibration of air distribution plate, make material in casing, do regular motion, the bubble that produces contacts with the material of motion in the process that moves upward, because collision effect, bubble is played fragmentation, bubble is existed with small form, eliminated the influence of bubble to fluidized state.The present invention is by the vibration of air distribution plate, make the interaction between the gas-solid two-phase obtain reinforcement, eliminated the influence of bubble to fluidized state, improved the efficiency of separation, strengthened the contact between the gas-solid two-phase, make medium solid when granularity is very little, also can reach good fluidized state, greatly reduce the raw meal particle size lower limit of separation, suppress even eliminated the generation of bubble in fluid bed, solved the contamination of products that causes because of medium macroscopic view back-mixing, for the efficient dry separation of coal and mineral provides reference.It is simple in structure, stable and reliable operation, and good separation effect has practicality widely.
