Description

The enhanced type vibration fluidizing drier

The utility model proposes a kind of novel drying equipment---enhanced type vibration fluidizing drier.

Existing vibration fluidizing drier, as accompanying drawing 1, it is mainly by inlet plenum 1, passing the material bed cross-flow of moving on plane perforate bed board 2 and the plate contacts and carries out heat exchange, tail gas the wet part of being evaporated by last cover 3 air outlet place bands and is discharged in the lump outside the drying machine, carries out dry purpose thereby reach to containing wet stock.Accompanying drawing 2 for another example, and the hot blast that it enters inlet plenum 21 by air inlet 22 flings the sidewall on air inlet opposite along its flow velocity direction, is upward through plane perforate bed board 24 along sidewall then and contacts with material.Because of hot blast fairly obvious in the bias current phenomenon of the mobile formed flow distribution trend of inlet plenum, but air inlet crosswind quantity not sufficient, and blind plate 25 crosswind amounts are excessive.The material proportion that is dried is more little or the hole rate is big more, causes the bias current phenomenon obvious more.Like this, contact inequality with material because of bias current brings hot blast on the one hand, material moisture content in both sides does not wait on the bed surface, has influenced dry mass and efficient; On the other hand, for the less material of proportion, even may puncture the bed of material of blind plate side, cause the hot blast short circuit, opposite side then produces Lou material, causes dry run normally not carry out.Because the perforate bed surface of existing vibration fluidizing drier, be one smooth, smooth, there is not the plane of any annex.Material mainly is to make material be in half by linear exciting force that vibrating motor produced to throw and hold or slip state on bed surface and motion, and the perforate that hot blast passes bed surface contacts with the material cross-flow and carries out heat exchange.The motion of material on bed surface is the Laminar Flow of rule, and bed of material density is very big, compares the expansion that does not have the bed of material basically with ebullated bed, and hot blast almost is to realize drying to wet stock by the gap of combining closely between material particles.The dislocation of material and storeroom, exchange like this, the probability that material contacts with hot-air chamber all is greatly limited, thereby correspondingly influences heating efficiency and drying efficiency.For some materials that easily bonds, the high density laminar flow of material flows and will cause the material caking on bed surface, influences drying effect, has limited the range of application of vibration fluidizing drier.

The purpose of this utility model is the improvement measure that proposes at the problem of existing hot blast bias current of existing fluidized drying machine and mobile this two aspect of material high density laminar flow.Thereby it is dry to reach further reinforcement, and expansion is to the purpose of material accommodation.

Technical solution of the present utility model: structure as shown in Figure 3.Be made up of inlet plenum, air inlet, plane perforate bed board, last cover, blind plate, the air inlet place in inlet plenum is provided with baffling gas distribution mechanism, and this baffling gas distribution mechanism is exactly the deflection plate of venetian blind type, and it is fixed or disassembled, and the distribution of gas adjustable angle is saved; Plane perforate bed board is a convex form that height is arranged, and its convex can be circular, oval-shaped, strip, fish back of the body shape.

Accompanying drawing 1,2 is respectively the prior art constructions schematic diagram.

Accompanying drawing 4,5 is respectively the plane opening bed board of convex structure and the structural representation of its several typical arrangement.Accompanying drawing 3 is structural representations of the present utility model.

Further specify technical solution of the present utility model below in conjunction with accompanying drawing 3:

At hot blast bias current in the inlet plenum, even the formation focused airflow punctures the bed of material, cause these problems that dry run is avoided as far as possible of hot blast skewness or short circuit, for better bringing into play the usefulness of vibration fluidizing drier, at the air inlet place of inlet plenum 33 baffling gas distribution mechanism 31 is set, to improve the flow regime of hot blast in inlet plenum, forcing hot blast evenly to pass the perforate bed board contacts with the material that is dried, reach good drying effect, its tool is stopped method, at the air inlet place of inlet plenum baffling gas distribution mechanism 31 is installed.This mechanism is according to the needs of intake air line technology arrangement position, can be that detachable and corresponding blind plate 32 form and exchange functions and see accompanying drawing 4, if the pipeline orientation determines, also can directly be fixed on the air inlet madial wall, sees accompanying drawing 5.Essence of the present utility model is to change the flow regime of hot blast, and it is material bed to avoid hot blast bias current and focused airflow bundle to puncture, and guarantees hot blast and is dried the material even contact.For a change the high density laminar flow flow regime of material on plane perforate bed board strengthened the dislocation and the exchange of storeroom, improves the contact area and the probability of material and hot blast, accelerates material bed dispersion or prevents material bed caking.In order to reach desirable drying effect, adopt special-shaped perforate bed board, so-called special-shaped perforate bed board is meant on the plane of the plane of existing fluidized drying machine perforate bed board, adopt punching press or prefabricated processing method to make perforate bed board in plane form clocklike some convex structures, see accompanying drawing 4, its convex structure can be circular, strip, fish do back of the body shape etc. various ways; Its arrangement regulation can be selected as required.The special-shaped bed board that has the convex structure of arranging by rule is compared with the plane bed board, remove and strengthened the bed board rigidity, avoided outside the bed board local vibration causes that residence time of material does not wait, the more important thing is the dispersion of having quickened lump material because of the existence of convex structure, dislocation and exchange between the material have been strengthened, avoided the high density laminar flow of vibration fluidizing drier and the caking that easy binding material may occur, dry tenacity and drying efficiency all are improved.

Because the utility model has improved hot blast flow regime and material movement state, and indexs such as dry product quality, drying efficiency, the thermal efficiency are improved.Simultaneously, further expanded the scope of application, as or material that hole rate bigger and the drying of dry run easy caking materials light partially to proportion.The utility model can be widely used in the piece of industries such as petrochemical industry, pharmacy, food, fertilizer, building materials, the drying process of powder or granule material.
