[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0033] Example 1:

[0034] A drying device for yellow paper processing includes a conveyor belt 1 and a drying box 2. The drying box 2 is located on the top of the conveyor belt 1. Several electric heating wires 3 are fixedly installed on the inner wall of the drying box 2. The top of the conveyor belt 1 is fixedly connected to two moisture removal pipes 4. The moisture removal pipes 4 are provided with a moisture removal mechanism inside to discharge moisture in the drying box 2 by generating suction.

[0035] The dehumidification mechanism includes a rotating block 5 disposed inside the housing, four fan blades 6 are fixedly connected to the surface of the rotating block 5, a rotating rod 7 is fixedly connected to the bottom of the rotating block 5, and a first bevel gear 8 is fixedly connected to the bottom of the rotating rod 7;

[0036] The heat recovery mechanism is fixedly arranged on the dehumidification pipe 4. When the dehumidification mechanism dehumidifies, the heat recovery mechanism will recover the heat energy in the moisture.

[0037] One of the implementation methods of this embodiment is: the dehumidification mechanism includes a double-headed motor 9 fixedly arranged on the top of the dryer, and the two output ends of the double-headed motor 9 are respectively fixedly connected to the traction rod 10, one end of the traction rod 10 passes through the interior of the dehumidification pipe 4, and is fixedly connected to the second bevel gear 11, the second bevel gear 11 is meshed with the first bevel gear 8, three humidity sensors 12 are fixedly installed on the inner wall of the drying box 2, and a controller 13 connected to the signal of the double-headed motor 9 is fixedly installed on one side of the drying box 2, and the controller 13 is connected to the signal of the humidity sensor 12.

[0038] In this embodiment, it is taken into consideration that the drying efficiency of the drying device in the prior art is poor when drying yellow paper. The main reason is that a large amount of moisture is generated during the drying process, which is difficult to be effectively discharged, thereby reducing the drying effect of the drying device. Therefore, by providing a dehumidification mechanism, when the moisture in the drying box 2 is too high, the humidity sensor 12 will receive a signal and transmit it to the controller 13. The built-in PLC module of the controller 13 will be started to drive the double-headed motor 9 to rotate. The rotation of the double-headed motor 9 will drive the traction rod 10 and the second bevel gear 11 to rotate. The second bevel gear 11 will drive the first bevel gear 8 and the rotating rod 7 to rotate. The rotating rod 7 will drive the rotating block 5 and the fan blade 6 to rotate around the second bearing 28, generating suction, and the moisture in the drying box 2 will be discharged from the drying box 2 through the dehumidification pipe 4, thereby achieving the dehumidification effect and thus improving the drying effect of the drying device;

[0039] The invention solves the problem that the drying efficiency of the drying device in the prior art is poor when drying yellow paper.

[0040] Preferably, the humidity sensors 12 are located at the front end, the middle end and the rear end of the drying box 2 respectively.

[0041] In this embodiment, by arranging the humidity sensors 12 at the front end, the middle end and the rear end of the drying box 2 respectively, the sensitivity of the sensing can be improved, thereby promoting the efficiency of moisture removal.

[0042] Preferably, two support blocks 27 are fixedly connected to the inner wall of the dehumidification pipe 4 , and a second bearing 28 is sleeved on the surface of the rotating rod 7 , and is rotatably connected to the support blocks 27 via the second bearing 28 .

[0043] In this embodiment, by providing the support block 27 and the second bearing 28, a support point can be provided for the rotating block 5, the rotating rod 7 and the fan blade 6, so that they can only rotate on the second bearing 28, while improving the smoothness of the rotation process.

[0044] Example 2:

[0045] On the basis of Example 1, the dehumidification mechanism in this embodiment can discharge the moisture in the drying box 2 to improve the drying effect. However, considering that the moisture will also take away some heat during the dehumidification process, if the internal temperature of the drying box 2 is too low, it will affect the drying effect. The heat recovery mechanism in this application includes a heat recovery box 14 fixedly connected to one side of the dehumidification mechanism, and three heat-conducting rods 15 are fixedly connected to the inner wall of the heat recovery box 14. One side of the heat-conducting rod 15 passes through the interior of the dehumidification pipe 4. The top of the heat recovery box 14 is fixedly connected to the air inlet pipe 16 through a first one-way valve, and the bottom of the heat recovery box 14 is fixedly connected to a transmission pipe 17. One end of the transmission pipe 17 is fixedly connected to a cylinder 18, and the bottom of the cylinder 18 is fixedly connected to an exhaust pipe 19. One end of the exhaust pipe 19 passes through the interior of the drying box 2 and is fixedly connected to an exhaust hood 20 through a second one-way valve.

[0046] The heat recovery mechanism also includes a screw rod 21 fixedly connected to one side of the second bevel gear 11. The surface of the screw rod 21 is transmission-connected to a moving block 22. One side of the moving block 22 is fixedly connected to a push rod 23. One end of the push rod 23 passes through the interior of the cylinder 18 and is fixedly connected to a push block 24. One side of the push block 24 is fixedly connected to a piston 25.

[0047] In this embodiment, it is taken into account that during the dehumidification process, moisture will also take away some heat. If the temperature inside the drying box 2 is too low, it will affect the drying effect. Therefore, by setting a heat recovery mechanism, while the moisture is discharged from the dehumidification pipe 4, the heat conducting rod 15 will absorb the heat in the moisture, and the other end of the heat conducting rod 15 will heat the air in the heat recovery box 14. At the same time, during the rotation of the second bevel gear 11, it will drive the screw rod 21 to rotate around the first bearing 26, and at the same time drive the moving block 22 to reciprocate. Figure 3 As shown, when the moving block 22 moves to the left, the hot air in the heat recovery box 14 will enter the interior of the cylinder 18 through the transmission pipe 17. When the moving block 22 moves to the right, the hot air in the cylinder 18 is squeezed and evenly enters the interior of the drying box 2 through the exhaust pipe 19 and the exhaust hood 20, achieving the effect of heat energy recovery and thus improving the drying effect.

[0048] The problem that the temperature inside the drying box 2 is too low will affect the drying effect due to the fact that moisture will also take away some heat during the dehumidification process is solved;

[0049] It should be noted that the first one-way valve is a valve that can only intake air into the heat recovery box 14, and the second one-way valve is a valve that can only exhaust air into the exhaust pipe 19. When the heat recovery box 14 enters the cylinder 18 through the transmission pipe 17, the heat recovery box 14 is under negative pressure, and the gas will enter the heat recovery box 14 through the air intake pipe 16 to replenish the gas, and the heat conducting rod 15 is made of copper.

[0050] Preferably, a first bearing 26 is provided at one end of the screw rod 21 , and the screw rod 21 is rotatably connected to the inner wall of the drying box 2 via the first bearing 26 .

[0051] In this embodiment, the first bearing 26 is provided to support the screw rod 21 , so that the screw rod 21 can rotate more smoothly.

[0052] Working principle: When the humidity in the drying box 2 is too high, the humidity sensor 12 will receive a signal and transmit it to the controller 13. The built-in PLC module of the controller 13 will start, driving the double-headed motor 9 to rotate. The rotation of the double-headed motor 9 will drive the traction rod 10 and the second bevel gear 11 to rotate. The second bevel gear 11 will drive the first bevel gear 8 and the rotating rod 7 to rotate. The rotating rod 7 will drive the rotating block 5 and the fan blade 6 to rotate around the second bearing 28, generating suction, and the moisture in the drying box 2 will be discharged from the drying box 2 through the dehumidification pipe 4, thereby achieving the dehumidification effect, thereby improving the drying effect of the drying device;

[0053] When the moisture is discharged from the moisture drain pipe 4, the heat conducting rod 15 absorbs the heat in the moisture, and the other end of the heat conducting rod 15 heats the air in the heat recovery box 14. At the same time, during the rotation of the second bevel gear 11, the screw rod 21 is driven to rotate around the first bearing 26, and the moving block 22 is driven to move back and forth. Figure 3 As shown, when the moving block 22 moves to the left, the hot air in the heat recovery box 14 will enter the interior of the cylinder 18 through the transmission pipe 17. When the moving block 22 moves to the right, the hot air in the cylinder 18 will be squeezed and will evenly enter the interior of the drying box 2 through the exhaust pipe 19 and the exhaust hood 20, thereby achieving the effect of heat energy recovery and improving the drying effect.

[0054] It should be noted that the electric heating wire 3, the double-headed motor 9, the humidity sensor 12 and the controller 13 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the electric heating wire 3, the double-headed motor 9, the humidity sensor 12 and the controller 13 are clear to those skilled in the art, so they will not be described in detail.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
