Abstract
The utility model discloses a fluidized bed dryer preventing materials from being bonded. The fluidized bed dryer comprises a boiling chamber, a distributing plate, a discharging port, an air outlet, an air inlet and a discharging port, the distributing plate is located inside the boiling chamber, the feeding port is formed in the upper portion of the boiling chamber, the air outlet is formed in the top of the boiling chamber, the air inlet and the discharging port are located in the lower portion of the boiling chamber, and the air inlet is connected with a draught fan. The fluidized bed dryer is characterized in that a filtering net and a heating device are arranged at the air inlet and are connected with the distributing plate through an air guiding channel, and a dispersing column is arranged on the distributing plate. The wind force can be guided towards the distribution plate in a centralized mode through the air guiding channel, the materials can be suspended and dried, the materials can be effectively prevented from being bonded into a large block due to the dead load through the action of the dispersing column, and the materials can be prevented from being bonded through the guided wind force.
Description
Technical field
This area belongs to chemical machinery field, is specifically related to a kind of fluidized bed dryer that can prevent that material from cohering.
Background technology
Fluidization technique (also claiming fluidization technology) originates from nineteen twenty-one.Fluidized bed dryer claims again fluid-bed dryer, fluidized drying refers to that drying medium makes solid particle under fluidized state, carry out dry process, its operation principle is: shot shape solid material is added in fluidized bed dryer by feeder, after pure air heating after filtration, by air blast, send into fluid bed bottom and contact with solid material through distribution grid, form the caloic exchange that fluidisation state reaches gas-solid.After dry materials, by discharge gate, discharged, waste gas is discharged after cyclone dust collectors group and sack cleaner recovery solid powder emptying by ebullated bed top.
Traditional fluidized bed dryer, air enters the rear unexpected amplification because of fluid bed inner space, make it to have with the fixing dynamics that contacts of material relax, often because not being dried timely and effectively, cause the bed of material to free and cohere because of deadweight.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of fluidized bed dryer that can prevent that material from cohering, and this fluidized bed dryer can increase air dynamics, effectively avoids material bed and coheres.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: the fluidized bed dryer that anti-material coheres, comprise boiling-house, be positioned at the distribution grid of boiling-house inside, be positioned at the charging aperture on boiling-house top, be positioned at the air outlet slit at boiling-house top, and the air intake and the discharging opening that are positioned at boiling-house below, air intake connecting fan, it is characterized in that, described air intake place is provided with screen pack and heater, and joins by air conducting passage and distribution grid, and described distribution grid is provided with dispersion post.By the effect of air conducting passage, the distribution grid that wind concentration can be led, is conducive to material suspendedly and dry, disperses the effect of post can effectively prevent that material from cohering into bulk because of deadweight, in conjunction with the wind-force of water conservancy diversion, is more conducive to prevent cohering of material.
Described air outlet slit place is provided with oppositely " Z " shape runner, be specially and comprise the upper and lower two-layer horizontal run of joining by vertical runner, wherein, upper strata horizontal run goes out to be provided with filter screen near vertical runner, vertically runner below is provided with the tapping channel that return duct connection discharging opening goes out, and the material of air being taken out of by filter screen stops to get off, and makes it to converge with dried material, prevent the loss of material, also can avoid the feed back dry waste causing again.
The fluidized bed dryer that anti-material described in the utility model coheres, effect by air conducting passage and dispersion post can effectively prevent that material is because of cohering that deadweight occurs, the traditional fluidized bed dryer of local is not only applicable to dry harder wet granular, and the material section taking out of because of air effectively reclaims, avoid waste, also anti-backflow is dried the waste of the energy causing again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1 boiling-house, 2 distribution grids, 3 charging apertures, 4 air outlet slits, 5 air intakes, 6 discharging openings, 7 screen packs, 8 heaters, 9 air conducting passages, 10 disperse post, 11 horizontal run, 12 vertical runners, 13 filter screens, 14 return ducts, 15 tapping channels, 16 blower fans.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Embodiment 1
