Abstract
The utility model discloses a side air-out type distribution plate of a fluidized bed dryer and belongs to the food-particle-shaped solid material drying technical field. The side air-out type distribution plate aims at overcoming the defects that the small channel flow short-circuit of airflow is easy to produce, air outlets are easy to block, the leakage is easy to produce, and the like in straight-flow distribution plates of the current fluidized bed dryers. The side air-out type distribution plate comprises a distribution plate; a plurality of hot air out pipes separated by a certain distance in the vertical and horizontal direction are distributed on the distribution plate and; the hot air out pipes penetrate the distribution plate; the upper ends of the hot air out pipes are closed; the side wall located on the upper portion of the distribution plate where the hot air out pipes penetrate out is provided with at least one air outlet; the hot air out pipes are communicated with a hot air branch pipe which is arranged under the distribution plate. The side air-out type distribution plate of the fluidized bed dryer is suitable for the new production or modification of the fluidized bed dryer.
Description
Technical field
The utility model relates to a kind of food granule shape solid material dry technology, particularly relates to a kind of side air-out formula distribution grid of fluidized bed dryer.
Background technology
In food processing process, often to be dried processing to the wet stock of solid particle shape, due to the character of sticking with paste as the intrinsic Yi Jiaoyi of food material and must keep the loose needs of being convenient to further processing technology enforcement, when dry, should avoid the drying medium that serviceability temperature is higher and allow wet stock transfixion.And fluidized bed dryer just in time meets above-mentioned requirements, therefore, fluidized bed dryer is after eighties of last century grows up the sixties, because it also has simple in structure simultaneously, easy to operate, the feature such as production capacity is large, has become Applications in Food Industry drying equipment the most widely at present.In fluidized bed dryer, granulated wet stock is deposited on distribution grid, hot-air is blown into material stack layer by equipment bottom by the distribution hole being clouded on distribution grid, and along with air velocity is increased to a certain degree, solid particle material will produce fluidized state in heap layer.Hot-air is here fluidizing agent, is again drying medium, and wet material is in thermal air current, is blown afloat, rolls in one side, and another side is constantly carrying out again heat transfer and mass transfer is movable, thereby reaches dry materials and the whole object being moved.At present, the distribution grid that fluidized bed dryer adopts adopts single flow distribution hole more.Because direct current distribution cellular type distribution plate orifices road is long, rigidity is large, simple in structure, easily manufactured, safeguard that easy, machinery-free telecontrol equipment own, use cost are low, are therefore subject to user's welcome very much.But, because the thermal current direction of single flow distribution grid, over against material stack layer, so easily produce ditch flow short-circuit phenomenon, affects the uniformity of dry materials, also easily produce the bonding phenomenon of material and equipment room; Air outlet, easily by stopping up compared with granule in material, breaks down simultaneously; When stopping supplying, air-flow also easily produces leakage phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of side air-out formula distribution grid of fluidized bed dryer, overcomes the single flow distribution grid adopting in current fluidized bed dryer and easily produces the easily deficiency such as blocked, easy generation leakage of the ditch flow short-circuit phenomenon of air-flow and air outlet.
The utility model is achieved by following technical proposals.
The utility model comprises distribution grid, on described distribution grid, to be laid with across a certain distance mutually a plurality of hot blasts to each in length and breadth, go out pipe, described hot blast goes out pipe and seals through described distribution grid, its upper end, at described hot blast, go out the sidewall that pipe is piercing in the top of described distribution grid and have at least one air outlet, the hot blast manifold below described hot blast goes out pipe and is located at described distribution grid is communicated with.Obviously, the technical program is that the air-out mode of the distribution grid in fluidized bed dryer is improved, and goes out pipe replace original direct current air outlet with described hot blast.At described hot blast, go out air outlet described in the side opening of pipe, by originally over against the material bed air-flow blowing out change into be laterally blown into material bed.Because the air-flow blowing out from described air outlet has certain kinetic energy, when running into material and stop, kinetic energy can partly be transferred to material particles, and the change of part travel direction, according to conservation of energy principle; Can realize equally material and be blown afloat, roll on one side, another side constantly conducts heat again, mass transfer movable, finally reaches dry materials and the whole object being moved.Even, owing to having stopped to occur that air-flow produces ditch flow short-circuit phenomenon, air-flow is more even in material bed middle dispersion, and above-mentioned effect only can be better.
In the utility model, blocked or when stopping air feed in order thoroughly to get rid of described air outlet, there is tiny material particle seepage to go out, the valve turning on can be is automatically housed outward at described air outlet, and described valve can be adjusted its open degree automatically with the power of air-flow, once stop air feed, fails to be convened for lack of a quorum and closes immediately, when opening, can also play the effect of the suitable fairlead bed of material of airflow direction below, thermal current is blown into by material bed below, can allow containing the discharge more smoothly from bottom to top of the air-flow after wet.The number that each described hot blast goes out the air port of outputing on pipe is three and at described hot blast, goes out on the outer wall of pipe uniformly, and like this, the air-flow that can make adjacent described hot blast go out in material bed between pipe more easily reaches uniform level.
Against existing technologies, the beneficial effects of the utility model are:
Can make hot-air flow distribution, more abundant with contacting of material particles more equably in material bed, be conducive to improve drying efficiency; Described air outlet is difficult for blocked or occurs leakage phenomenon, and drying operation can be carried out smoothly safely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, and the A that Fig. 2 is Fig. 1 is to view.In figure: l, distribution grid, 2, hot blast goes out pipe, 3, air outlet, 4, hot blast manifold, 5, valve.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model will be further described.
In the specific implementation, the air-flow in hot blast manifold 4 should be through pre-distribution, so just can accomplish substantially equal on pressure head and flow of each air outlet 3 air-flow that blows out.Valve 5 can process the flexibility identical with the outer opening's edge arc of air outlet 3 or set up cushion in the one side towards air outlet 3, makes valve 5 when closing, have better seal.The upper end that valve 5 and hot blast go out pipe 2 is hinged, and in order to prevent when hot-air flow is larger, valve 5 is blown afloat excessively and 90 °, super limit, can fill spacing pin in the above.
