Detailed Description

As shown in figure 1, the wood veneer dryer provided by the utility model comprises a drying box 3 and a moisture exhaust pipe 9 arranged on the drying box 3, a flat hot plate 15 is arranged in the drying box 3, a plurality of rollers 18 are arranged in parallel above the hot plate 15, a chain wheel 10 is fixed on the roller shaft, the chain wheel 10 is engaged on a transmission chain 17 on a guide rail arranged on the inner side edge of the drying box 3, a motor 20 is arranged on the drying box 3, a rotating chain wheel 5 is arranged on a rotating shaft arranged on the motor 20, the rotating chain wheel 5 is arranged on the chain 17, roller bearing blocking seats for preventing the roller 18 from moving left and right are arranged on two sides of the roller shaft, a furnace body 2 is connected below the hot plate 15, a furnace chamber 19 is arranged in the furnace body 2, a furnace grate is arranged in the furnace chamber 19, the hot plate 15 is arranged on the furnace chamber 19, a furnace door 14 is arranged on the furnace body 2, a burner 1, the smoke pipe 7 is provided with a smoke exhaust pipe 8, the other side of the smoke exhaust pipe is connected with an induced draft fan 6, the induced draft fan 6 is fixed below a hot plate in the drying box 3, the burner 1 is provided with a feeding port 13, an inclined fire inlet pipe 12 is arranged between the furnace body 2 and the burner 1, the fire inlet pipe 12 is arranged above the furnace grate, the roller 18 is a hemp roller with a comb tooth line on the surface, the drying box 3 is provided with a support 11, and the hot plate 15 is a heat conducting plate.

When the heating device is used specifically, firstly, combustible materials placed on a grate 19 in a hearth are ignited, or combustible materials such as coal-fired particles, gasoline and the like are added at any time through a feeding port 13 of the combustion machine 1 so as to heat a hot plate 15 arranged on the hearth 19, the temperature of the hot plate 15 and the temperature in the drying box 3 are gradually increased, and the temperature of the roller 18 is also gradually increased. Then the power supply of the motor 20 and the induced draft fan 6 is switched on.

The motor 20 drives the rotating shaft arranged on the motor 20 and the rotating chain wheel 5 arranged on the rotating shaft to rotate, the rotating chain wheel 5 drives the chain 17 to move, the chain 17 drives the chain wheel 10 arranged on the chain 17 and the roller shaft to rotate, and the roller bearing blocking seats for preventing the roller 18 from moving left and right are arranged on two sides of the roller shaft, so the roller 18 can only rotate at the original position. At this time, the veneer 21 to be dried is fed into the feeding port 4, the veneer is brought into the drying box 3 under the rotation of the roller 18, the moisture in the wood is evaporated into the drying box 3 by the veneer in the drying box 3 under the drying of the high-temperature drying box 3 and the roller 18, the moisture is discharged out of the drying box 3 through the moisture exhaust pipe 9, and finally the dried wood veneer is discharged out of the drying box 3 from the discharging port 16.

During the working period, the smoke generated during the combustion of the fire coal, wood or particle fuel, oil and various fuels in the hearth 19 or the combustor 1 circulates between the hearth and the hot plate 15 under the action of the induced draft fan 6, and the redundant smoke is discharged through the smoke pipe 7 and the smoke exhaust pipe 8 in sequence.

Because the utility model discloses an utilize the flame in furnace 19 or the combustor 1 directly to pass heat energy to hot plate 15, the higher authority is that roller 18 conveys the principle that timber veneer moved ahead and dries timber, so, has following advantage with current two roller dryer contrast: the electric energy can be saved by less than 50%, the fuel can be saved by less than 60%, the working efficiency can be improved by more than 40%, a boiler room and a boiler do not need to be built, a pipeline does not need to be installed, the procedure of the boiler does not need to be handled, the boiler does not need to be operated, and the like.
