Abstract
The present invention is the energy-conservation spray box of a kind of veneer dryer, its structure comprises spray box body 3, this spray box body 3 is welded into right-angled trapezium by forward and backward side plate, cover plate and spray box base plate 1, the top (microcephaly) of this spray box body 3 is closed, spray box body 3 bottom (major part) is unlimited spray box air inlet 10, described spray box base plate 1 has rectangle spray groove 2, rectangle spray groove 2 has slit-shaped nozzle 4, nozzle 4 surface thereof mounting guiding board 5.Advantage: replace loose structure with flume structure, dry gas stream, by the oblique ejection of deflector with certain inclination angle, synthesizes with air-flow lateral velocity, reaches the actual effect that air-flow is vertically sprayed onto veneer surface.Be conducive to the boundary layer destroying veneer surface like this, accelerate the process of heat transfer and moisture evaporation, reach and improve drying efficiency and energy-conservation object.Meanwhile, dry gas stream evenly sprays from slit, and centre cuts off a little continuously, and veneer surface can dried uniform stream heating simultaneously.
Description
Technical field
What the present invention relates to is the energy-conservation spray box of a kind of veneer dryer, belongs to veneer dryer energy saver technical field.
Background technology
Veneer drying is the important process of plywood production, and veneer dryer is one of capital equipment of plywood production, for carrying out drying to the thickness veneer of all size, makes the whole moisture content of plank reach technological requirement by veneer drying.The spray box of existing veneer dryer adopts the structure of spray orifice, dry gas stream sprays vertically downward, its major defect is: (1) air-flow is sprayed vertically downward by spray orifice, owing to there is certain lateral velocity near veneer airflow on surface, therefore in fact dry gas stream is not vertically be ejected on veneer, but has certain angle of inclination; (2) nozzle of veneer dryer spray box is loose structure, the closed interval of certain area is there is between several spray orifices, in dry run, the place at spray orifice interval does not have air-flow to spray, therefore dry gas stream can not evenly be ejected into veneer surface everywhere, thus affects veneer drying effect.
Summary of the invention
What the present invention proposed is the energy-conservation spray box of a kind of veneer dryer, its object is intended to the above-mentioned defect overcome existing for prior art, improve nozzle form and the structure of conventional dryers spray box, improve jet-impingement drying effect and uniform drying, veneer is heated with dry run in can ensure that hot-air is vertical uniformly and be injected in steel slab surface, reach and enhance productivity, reduce the object of energy consumption for drying.
Technical solution of the present invention: the energy-conservation spray box of a kind of veneer dryer, its structure comprises spray box body, this spray box body is welded into right-angled trapezium by forward and backward side plate, cover plate and spray box base plate, the top (microcephaly) of this spray box body is closed, spray box body bottom (major part) is unlimited spray box air inlet, described spray box base plate has rectangle spray groove, and rectangle spray groove has slit-shaped nozzle, slit-shaped nozzle is equipped with deflector, and described deflector is hook solid.
Advantage of the present invention: compared with conventional dryers spray box, the present invention makes important improvement to nozzle arrangements, loose structure is replaced with flume structure, the deflector oblique ejection of dry gas stream by having certain inclination angle, synthesize with air-flow lateral velocity, reach the actual effect that air-flow is vertically sprayed onto veneer surface.Be conducive to the boundary layer destroying veneer surface like this, accelerate the process of heat transfer and moisture evaporation, reach and improve drying efficiency and energy-conservation object.Meanwhile, dry gas stream evenly sprays from slit, and centre cuts off a little continuously, and veneer surface can dried uniform stream heating simultaneously.Dry gas stream is more evenly distributed compared with the cellular type drying machine spray box of routine, and air-flow coverage rate is wider, can effectively prevent veneer surface from producing the product defectses such as cracking owing to heating uneven.By above improvement, can drying time be shortened, enhance productivity, effectively reduce energy consumption for drying and improve dry products quality.

Detailed description of the invention
Contrast accompanying drawing, the energy-conservation spray box of veneer dryer, its structure comprises spray box body 3, this spray box body 3 welds rectangular trapezoidal shape by forward and backward side plate, cover plate and spray box base plate 1, the top (microcephaly) of this spray box body 3 is closed, spray box body 3 bottom (major part) is unlimited spray box air inlet 10, described spray box base plate 1 has rectangle spray groove 2, rectangle spray groove 2 has slit, slit forms nozzle 4, nozzle 4 is equipped with deflector 5, described deflector 5 hook solid, plays the effect changing jet-stream wind direction.
The mode that the energy-conservation spray box 7 of veneer dryer is bolted is arranged in drying machine frame 9, in the course of work, hot-air is by hothouse air intake passage 6, rectangle spray groove ejection on the energy-conservation spray box 7 of veneer dryer, is injected in veneer 8 surface under the effect of deflector 5.
Embodiment
The energy-conservation spray box of veneer dryer 7 is combined by welding by spray box body and the spray box base plate with some roads Continuous Rectangular spray groove, and the forward and backward side plate wherein in spray box body is right-angled trapezium, the angle of inclination that cover plate band is certain, and spray box base plate is level.One end of this trapezoidal cabinet microcephaly is one end that is closed, major part is unlimited, and the one end opened wide forms the spray box air inlet 10 of spray box.Spray box body 3 is arranged in the drying machine frame 9 of hothouse by bolt, the energy-conservation spray box 7 of upper and lower two veneer dryers is installed in pairs in opposite directions in use, namely the cover plate descending the energy-conservation spray box 7 of veneer dryer down and spray box base plate 1 upward, corresponding with the base plate of the energy-conservation spray box of upper veneer dryer 7, and certain spacing of being separated by between two pieces of spray box base plates, this spacing forms the hothouse air intake passage 6 of veneer.During veneer dryer work, air through heater heating enters spray box air inlet 10 from hothouse air intake passage 6, veneer 8 is advanced forward in the horizontal direction on transmission guipure, hot-air is by rectangle spray groove 2 and deflector 5, evenly be injected in veneer 8 surface, moisture in evaporation veneer, reaches the object of dried single board.
