Description
Technical field
The utility model relates to a kind of dryer, particularly lower returning type wood single-plate dryer.
Background technology
At present, the wood single-plate dryer adopts two roller oven dry principles mostly, with blower fan the heat energy in the warm air curtain is blowed to veneer by square air jet pipe, thereby reaches the oven dry purpose.But the wood single-plate dryer of traditional structure because warm air curtain and warm air curtain blower fan are arranged on the upside of two rollers, causes heat to be difficult to be absorbed, and heat exhaustion is bigger, and wind resistance is bigger, and dryer is bulky.And what the wood single-plate dryer of traditional structure adopted is the square air jet pipe of horizontal, therefore, causes air jet pipe to stop up easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of thermal efficiency height, energy-conservation, lower returning type wood single-plate dryer that volume is little, cheap for manufacturing cost are provided.
To achieve these goals, the utility model has been taked following technical scheme:
The utility model lower returning type wood single-plate dryer, comprise drying baker, be arranged on damp air discharge pipe on the drying baker, be set up in parallel at least two in drying baker pressure roller and with each on pressure roller at least two lower compression rollers one to one.By described go up pressure roller group that pressure roller and lower compression roller constitute below be provided with warm air curtain and blower fan, the upper end of the main air duct of described blower fan be connected with air jet pipe on the quadrangle between the pressure roller on per two and under the quadrangle between per two lower compression rollers air jet pipe, an air jet pipe and a tetragonal linea angulata of air jet pipe down face ground on the described quadrangle, and the edged surface relative with it is provided with the spray groove.
Since the utility model with put on traditional warm air curtain and blower fan thereof change place two rollers below, reduced the volume of dryer, reduced manufacturing cost, be convenient to I﹠M; Because the blower fan and the air channel that are arranged on below two rollers are direct-connected, are the air jet pipe air feed directly, thereby have reduced bent angle, have reduced resistance, have improved fan efficiency; Because during the underlying warm air curtain, heat upwards flows and acts directly on the wood single-plate, helps heat absorption; Because it is blocked that air jet pipe employing inclined type, a diagonal that makes square air jet pipe perpendicular to the bottom surface, are difficult for, and on the superincumbent angle jet groove is set, thereby can reduce the distance between air jet pipe and wood single-plate, and hot blast is acted on the veneer more effectively.
Description of drawings
Fig. 1 is the utility model lower returning type wood single-plate dryer.
Fig. 2 be among Fig. 1 A to structural representation.
Fig. 3 be among Fig. 1 B to partial sectional view.
The specific embodiment
As shown in Figure 1 to Figure 3, the utility model lower returning type wood single-plate dryer, comprise drying baker 17, be arranged on damp air discharge pipe 22 on the drying baker 17, be set up in parallel on two in drying baker 17 pressure roller 6 at least and with each on pressure roller 6 at least two lower compression rollers 9 one to one.By described go up pressure roller group that pressure roller 6 and lower compression roller 9 constitute below be provided with warm air curtain 20 and warm air curtain blower fan 13, the upper end of the main air duct 12 of described blower fan 13 is connected with air jet pipe 10 and the square air jet pipe 11 down between per two lower compression rollers 9 on square between the pressure roller 6 on per two, an air jet pipe 10 and a tetragonal linea angulata of air jet pipe 11 down face ground on the described quadrangle, and the edged surface relative with it is provided with the spray groove.
Be provided with operation motor 1 in the described drying baker 17, operation motor 1 is connected with sprocket wheel guide wheel 2 by driving chain 8, sprocket wheel guide wheel 2 is mutually meshing with sprocket wheel 3, be fixed with the lower gear 5 that drives lower compression roller 9 rotations on the axle of sprocket wheel 3, be fixed with on intermeshing 4 the axle of cogging of lower gear 5 pressure roller 6 spool.Rigid bearing block 7 is located at described two ends of going up pressure roller 6 and lower compression roller 9, is used to limit moving of pressure roller.The axle of described blower fan 13 is positioned on the blower fan axle bed 14, and 13 of blower fans pass through belt 16 and are connected with blower motor 15.
Running of the present utility model is as follows: at first the starting operation motor 1, drive 2 rotations of sprocket wheel guide wheel by driving chain 8, drive sprocket wheel 3 rotations by driving chain again, sprocket wheel 3 drives 5 rotations of coaxial lower gear, drives lower compression roller 9 rotations that are connected with gear 5 simultaneously; Lower gear 5 drives 4 reverse rotations that cog that are engaged with again, drive simultaneously and the 4 last pressure rollers that are connected, 6 rotations that cog, thereby pressure roller 6 and lower compression roller 9 are moved vis-a-vis, and then the clamping wood single-plate moves between two pressure rollers.
Heat supply principle of the present utility model is: open the heat supply pipeline 18 that is arranged on the warm air curtain 20, with warm air curtain 20 preheatings.Open blower fan 15 then, start the blower fan 13 that is fixed on the blower fan axle bed 14 by belt 16, air is sent to main air duct 12 from warm air curtain 20 via bellows 19, enter tilting square going up in air jet pipe 10 and the following air jet pipe 11 respectively by air port 21 again, and by being arranged on spray groove on the air jet pipe, thereby reach dry purpose to wood single-plate to be dried spray hot gas.
