The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] Example

[0053] See also Figures 1 to 9 , shown is a wood drying device according to an embodiment of the present invention, comprising a drying box 100, a plurality of material racks 200, and a plurality of drying assemblies 300. The plurality of material racks 200 are spaced apart in the drying box 100, and a drying assembly 300 is provided on opposite sides of each material rack 200. The material racks 200 are used to carry disc-shaped wood;

[0054] The drying assembly 300 includes a steam container having a plurality of annular chambers, a plurality of steam conduction switches disposed on each annular chamber, at least one spiral guide rail, at least one steam spray head slidably connected to the spiral guide rail, and a driving component for driving the steam spray head to intermittently slide along a guide path of the spiral guide rail.

[0055] The guide path of the spiral guide rail extends across the plurality of annular chambers, so that the plurality of steam conduction switches on each annular chamber are all located within the guide path of the spiral guide rail, so that when the steam spray head intermittently slides within the spiral guide rail, the steam spray head is connected to the corresponding steam conduction switch to transmit the steam in the corresponding annular chamber to the steam spray head;

[0056] The multiple annular chambers are nested with each other, each annular chamber is used to accommodate steam of a certain temperature, and the steam temperature in the multiple annular chambers increases from the outer annular chamber to the middle annular chamber.

[0057] It should be noted that, in actual situations, since the density of the middle of the disc-shaped wood is much greater than the density of the outer side, during the drying process, it is necessary to precisely dry the density of different areas of the disc-shaped wood to reduce the drying time of the disc-shaped wood.

[0058] In a specific implementation, a plurality of material racks 200 in this example can be used to place a plurality of disc-shaped wood materials, and a drying assembly 300 is provided on opposite sides of each material rack 200, so that when drying a plurality of disc-shaped wood materials, the driving component in the drying assembly 300 can drive the steam nozzle to slide intermittently along the guide path of the spiral guide rail, so that the steam nozzle can intermittently move in a spiral manner from the outside to the inside or from the inside to the outside along the shape of the disc-shaped wood materials, and during the movement, the steam nozzle can face the corresponding steam conduction switch, so that the steam in the annular chamber corresponding to the steam conduction switch can be transmitted to the steam nozzle, and the steam nozzle is used to output steam of corresponding temperature to the disc-shaped wood materials. The surface of the material is moved to achieve the purpose of drying the disc-shaped wood, and at the same time, in order to accurately dry the disc-shaped wood according to the density of different areas of the disc-shaped wood, in this example, the guide path of the spiral guide rail is spread over multiple annular chambers, each annular chamber is used to accommodate steam of a temperature, and the steam temperature in the multiple annular chambers increases successively from the outer annular chamber to the middle annular chamber. Steam of different temperatures is accommodated by different annular chambers, so that when the steam nozzle moves to the corresponding area of ​​the disc-shaped wood, the steam nozzle will be connected with the annular chamber of the corresponding temperature, and the corresponding area of ​​the disc-shaped wood will be accurately dried by the steam of the corresponding temperature, thereby changing the drying method of the disc-shaped wood in the existing technology and solving the technical problem of long drying time.

[0059] For further understanding of this case, please refer to Figure 7 As shown, the multiple annular chambers shown in this example can respectively include a first annular chamber 330, a second annular chamber 340 and a third annular chamber 350. The first annular chamber 330, the second annular chamber 340 and the third annular chamber 350 are nested in sequence. The first annular chamber 330 is used to accommodate steam at a first temperature, the second annular chamber 340 is used to accommodate steam at a second temperature, and the third annular chamber 350 is used to accommodate steam at a third temperature, wherein the first temperature is greater than the second temperature, and the second temperature is greater than the third temperature.

[0060] Specifically, the temperature of the steam contained in the first annular chamber 330 is the highest, the temperature of the steam contained in the third annular chamber 350 is the lowest, and the temperature of the steam contained in the second annular chamber 340 is between the highest temperature and the lowest temperature. In other words, the steam in the first annular chamber 330 is the highest temperature, so that when the steam nozzle moves to the steam conduction switch corresponding to the first annular chamber 330, the steam with the highest temperature in the first annular chamber 330 will directly act on the center of the disc-shaped wood, and the central area of ​​the disc-shaped wood is dried using the steam with the highest temperature. It should be noted that the center of the disc-shaped wood is The area is the area with the highest density. The use of the highest temperature steam can quickly dry the central area with the highest density. Similarly, when the steam nozzle moves to the steam conduction switch corresponding to the third annular chamber 350, the steam with the lowest temperature in the third annular chamber 350 will directly act on the outer area of ​​the disc-shaped wood, and the outer area of ​​the disc-shaped wood is dried using the steam with the lowest temperature. It should be noted that the outer area of ​​the disc-shaped wood is the area with the lowest density. In other words, the density of different areas of the disc-shaped wood can be accurately dried, which can greatly reduce the drying time of the disc-shaped wood.

[0061] It should be noted that in some initial states, since the disc-shaped wood itself is at a natural temperature, in order to avoid the problem of cracking of the disc-shaped wood, the disc-shaped wood can be preheated with steam at a preheating temperature in the initial state. That is to say, the temperature of the steam in the first annular chamber 330, the temperature of the steam in the second annular chamber 340, and the temperature of the steam in the third annular chamber 350 can first be preheated with the preheating temperature to preheat the disc-shaped wood. Moreover, since the density of different areas of the disc-shaped wood is different, during the preheating process, the steam temperature can also be increased from the outer annular chamber to the middle annular chamber to preheat the disc-shaped wood, so that different areas of the disc-shaped wood can achieve an effective preheating effect in a short time.

[0062] In addition, to facilitate the transmission of steam to the first annular chamber 330, the second annular chamber 340, and the third annular chamber 350, in this embodiment, the drying assembly 300 further includes a plurality of first transmission pipes 370, a plurality of second transmission pipes 371, a plurality of third transmission pipes 372, and a plurality of steam pumps 380, each steam pump 380 being configured to output steam of a different temperature.

[0063] One end of each of the plurality of first transmission pipes 370 is connected to each of the plurality of first annular chambers 330 , and the other ends of each of the plurality of first transmission pipes 370 are connected to each other and to corresponding steam pumps 380 to transmit steam at the first temperature into the plurality of first annular chambers 330 .

[0064] One end of the plurality of second transmission pipes 371 is respectively connected to the plurality of second annular chambers 340 , and the other ends of the plurality of second transmission pipes 371 are connected to each other and to corresponding steam pumps 380 to transmit steam at the second temperature into the plurality of second annular chambers 340 ;

[0065] One ends of the plurality of third transmission pipes 372 are respectively connected to the plurality of third annular chambers 350 , and the other ends of the plurality of third transmission pipes 372 are connected to each other and to the corresponding steam pumps 380 to transmit steam of the third temperature into the plurality of third annular chambers 350 .

[0066] For details, please refer again to Figure 7 As shown, there can be three of the multiple steam pumps 380, for example, the first steam pump 380 is used to output steam at a first temperature, the second steam pump 380 is used to output steam at a second temperature, and the third steam pump 380 is used to output steam at a third temperature. Steam of three temperatures can be output through the three steam pumps 380, and the steam of three temperatures can be respectively transmitted to the multiple first annular chambers 330, the multiple second annular chambers 340 and the multiple third annular chambers 350.

[0067] It should be noted that in this example, the first annular chamber 330, the second annular chamber 340 and the third annular chamber 350 do not limit the number of annular chambers, and other numbers of annular chambers can also be used. When other numbers of annular chambers are used, the corresponding number of transmission pipes and the number of steam pumps 380 are set in a one-to-one correspondence with the number of annular chambers. It should be noted that the transmission pipe is a general term for the above-mentioned first transmission pipe 370, the second transmission pipe 371 and the third transmission pipe 372, and no special explanation is given here.

[0068] In addition, it should be noted that in order to facilitate the movement of the steam nozzle, in this example, the driving component includes a driving member having at least one output shaft and at least one rotating member having a guide groove. The driving member is arranged at the center of the steam container, and the output shaft is connected to the rotating member to drive the rotating member to rotate, wherein a part of the steam nozzle is slidably connected in the guide groove.

[0069] Specifically, the driving member shown in this embodiment can adopt the motor in the prior art, and the motor can be used to drive the rotating member to rotate, and the length of the rotating member can be equal to the radius of the steam container, so that when the rotating member rotates, it can fully cover the surface of the disc-shaped wood, and when the rotating member rotates, the guide groove is set, so that the rotating member can apply thrust to the steam nozzle head, so that the steam nozzle head moves in the spiral guide rail, and the steam nozzle head slides relatively in the guide groove.

[0070] It should be noted that the above-mentioned first annular chamber 330, second annular chamber 340 and third annular chamber 350 can be formed by arranging multiple annular heat insulation plates in the steam container. The heat insulation properties of the heat insulation plates are utilized to ensure that the steam temperatures between the first annular chamber 330, the second annular chamber 340 and the third annular chamber 350 will not affect each other. It should be noted that the heat insulation plates have heat insulation functions and are conventional existing technologies in this field, so they are not specifically explained here.

[0071] In addition, to improve the practicality of the drying device in the embodiment, in this embodiment, the multiple drying components 300 include multiple drying components a310 arranged in the middle of the drying box 100 and two drying components b320 arranged at the top and bottom of the drying box 100.

[0072] See also Figure 4 and Figure 5 As shown, the drying assembly a310 includes a steam receiving member a311 having multiple annular chambers, two spiral guide rails a312, two steam nozzles a313, two sets of multiple steam conduction switches a314, and a driving component a315. The driving component a315 includes a driving member a3152 having two output shafts a3151 and two rotating members a3154 having guide grooves a3153. It should be noted that the multiple annular chambers in the steam receiving member a311 are the first annular chamber 330, the second annular chamber 340, and the third annular chamber 350 mentioned above. For details, please refer to Figure 7 As shown;

[0073] A spiral guide rail a312, a steam nozzle a313, a plurality of steam conduction switches a314, an output shaft a3151 and a rotating member a3154 are provided on one side of the steam receiving member a311.

[0074] Another spiral guide rail a312, another steam nozzle a313, another set of multiple steam conduction switches a314, another output shaft a3151 and another rotating member a3154 are arranged on the other side of the steam receiving member a311.

[0075] See also Figure 6 As shown, the drying component b320 includes a steam container b321 having a plurality of annular chambers, a spiral guide rail b322, a steam nozzle b323, a plurality of steam conduction switches b324 and a driving component b325. The driving component b325 includes a driving component b3252 having an output shaft b3251 and a rotating component b3254 having a guide groove b3253. It should be noted that the plurality of annular chambers in the steam container b321 are the same as the plurality of annular chambers in the steam container a311. In view of the fact that the plurality of annular chambers in the steam container b321 have the same structure as the plurality of annular chambers in the steam container a311, in this embodiment, Figure 7 The structure shown in FIG is represented as a plurality of annular chambers in the steam container a311 and a plurality of annular chambers in the steam container b321;

[0076] Among them, the spiral guide rail b322, the steam nozzle b323, a plurality of steam conduction switches b324, the output shaft b3251 and the rotating member b3254 are arranged on a side of the steam receiving member b321 opposite to the adjacent steam receiving member a311.

[0077] To facilitate understanding of the drying process of the disc-shaped wood by the above-mentioned multiple drying components a310 and the two drying components b320, three disc-shaped wood are used as an example, namely the first disc-shaped wood, the second disc-shaped wood and the third disc-shaped wood. The first disc-shaped wood is located at the top of the drying box 100, the second disc-shaped wood is located in the middle of the drying box 100, and the third disc-shaped wood is located at the bottom of the drying box 100. There are two drying components a310, and they are located in the middle of the drying box 100.

[0078] See also Figure 2 and Figure 3 As shown, when drying the first disk-shaped wood, the second disk-shaped wood, and the third disk-shaped wood, first, the first drying assembly b320 located at the top of the drying box 100 can be used to dry the upper surface of the first disk-shaped wood, and then the first drying assembly a310 can be used to dry the lower surface of the first disk-shaped wood. In addition, since the driving member a3152 in the drying assembly a310 has two output shafts a3151, the two output shafts a3151 respectively drive the two rotating members a3154 to rotate, so that the two rotating members a3154 can be used to rotate. When the rotating part a3154 drives the two steam nozzles a313 to move, the two steam nozzles a313 have corresponding steam conduction switches a314, that is, the first drying component a310 can be used to dry the lower surface of the first disc-shaped wood and the upper surface of the second disc-shaped wood. Similarly, the second drying component a310 can be used to dry the lower surface of the second disc-shaped wood and the upper surface of the third disc-shaped wood. Finally, the second drying component b320 can be used to dry the lower surface of the third disc-shaped wood.

[0079] It should be noted that in the drying component a310, the driving component a3152 can adopt a dual-axis motor in the prior art, and in the drying component b320, the driving component b3252 can adopt a motor with an output shaft in the prior art, and there is only one steam container a311 with multiple annular chambers in the drying component a310. One steam container a311 can provide steam to two steam nozzles a313, thereby reducing the number of steam containers a311 arranged and effectively reducing the manufacturing cost of the device.

[0080] Furthermore, in some preferred embodiments, one of the two steam nozzles a313 in the drying assembly a310 is initially arranged in the central area of ​​a spiral guide rail a312, and another of the two steam nozzles a313 is initially arranged in the outer area of ​​the other spiral guide rail a312, wherein the two spiral guide rails a312 are symmetrically arranged, and by limiting the initial positions of the two steam nozzles a313, when the two steam nozzles a313 output steam at the same time, it is possible to ensure that sufficient steam is output to the surface of the disc-shaped wood. For example, when the first steam nozzle a313 outputs steam, , will directly obtain the steam in the first annular chamber 330, and the second steam nozzle a313 will directly obtain the steam in the third annular chamber 350 when outputting steam, and the steam in the first annular chamber 330 and the steam in the second annular chamber 340 are separated to ensure that a single steam nozzle a313 obtains the steam in a single annular chamber. It should be noted that in order to avoid the two steam nozzles a313 using the steam in the second annular chamber 340 together, there can be two second annular chambers 340, that is, the two steam nozzles a313 have sufficient steam output to dry the upper and lower surfaces of the two disc-shaped wood respectively.

[0081] It should be noted that the steam container b321 in the drying component b320 can also be arranged in the manner of the two steam containers a311 in the above-mentioned drying component a310. For example, in the initial state, the steam nozzle a313 is set in the central area of ​​the steam container a311, and the corresponding steam container b321 is set in the outer area of ​​the steam container b321.

[0082] In addition, to ensure that steam can be transmitted to the steam nozzle a313 and the steam nozzle b323, in this example, the steam conduction switch a314 and the steam conduction switch b324 have the same structure, please refer to Figure 8 As shown in FIG. 3 , the specific structure of the steam conduction switch a314 and the steam conduction switch b324 includes two N-pole magnetic disks 360 and an S-pole magnetic disk 361. It should be noted that, in Figure 8 In the example, the steam nozzle a313 is used as an example;

[0083] One of the two N-pole magnetic disks 360 is movably connected to the annular chamber, and the other is fixedly connected to the steam nozzle;

[0084] The S-pole magnetic disk 361 is disposed in the annular chamber and is magnetically connected to a corresponding N-pole magnetic disk 360, thereby sealing the steam in the annular chamber.

[0085] When the steam nozzle moves to be opposite to the steam conduction switch, the two N-pole magnetic disks 360 repel each other, so that the steam in the annular chamber is transmitted to the steam nozzle, and the steam conduction switch also includes a plurality of cover bodies 362 with transmission holes, and the cover bodies 362 are arranged on the outer side of a corresponding N-pole magnetic disk 360.

[0086] Please refer to the following for details: Figure 8 and Figure 9 As shown, in this embodiment, the cover 362 is used to prevent an N-pole magnetic disk 360 from falling into the interior of the annular chamber. In order to transmit the gas to the interior of the steam nozzle, the steam nozzle can allow the two N-pole magnetic disks 360 to face each other during the intermittent movement. The mutual repulsion of the two N-pole magnetic disks 360 is used to form a hole in the annular chamber. At this time, the steam in the annular chamber will be directly transmitted to the steam nozzle. When the annular chamber needs to be sealed, the steam nozzle will move intermittently again to separate the two N-pole magnetic disks 360, and an N-pole magnetic disk 360 arranged in the annular chamber will be magnetically connected to the S-pole magnetic disk 361 to complete the sealing of the annular chamber.

[0087] It should be noted that a sealing gasket can be arranged between an N-pole magnetic disk 360 and an S-pole magnetic disk 361 arranged in the annular chamber to ensure the sealing of the annular chamber, and the magnetic attraction between an N-pole magnetic disk 360 and an S-pole magnetic disk 361 arranged in the annular chamber can be artificially intervened in the existing technology so that the magnetic attraction between the N-pole magnetic disk 360 and the S-pole magnetic disk 361 is smaller than the repulsive force between the two N-pole magnetic disks 360. It should be noted that there is a cavity for transmitting steam inside the steam nozzle, and an N-pole magnetic disk 360 can be fixed in the cavity. Since the steam nozzle belongs to the conventional technology in this field, it is not specifically explained here.

[0088] In summary, a wood drying device provided by one embodiment of the present invention arranges a plurality of material racks 200 and a plurality of drying components 300 in a drying box 100, so that when drying a plurality of disc-shaped wood materials, the driving component in the drying component 300 can drive the steam nozzle to slide intermittently along the guide path of the spiral guide rail, so that the steam nozzle can intermittently move in a spiral manner from the outside to the inside or from the inside to the outside along the shape of the disc-shaped wood materials, and during the movement, the steam nozzle can face the corresponding steam conduction switch, so that the steam in the annular chamber corresponding to the steam conduction switch can be transmitted to the steam nozzle, and the steam nozzle is used to output steam of corresponding temperature to the disc-shaped wood materials. surface, so as to achieve the purpose of drying the disc-shaped wood, and at the same time, to accurately dry the disc-shaped wood according to the density of different areas, in the present invention, the guide path of the spiral guide rail is spread over a plurality of annular chambers, each annular chamber is used to accommodate steam of a temperature, and the steam temperature in the plurality of annular chambers increases successively from the outer annular chamber to the middle annular chamber. By accommodating steam of different temperatures in different annular chambers, when the steam nozzle moves to the corresponding area of ​​the disc-shaped wood, the steam nozzle will be connected with the annular chamber of the corresponding temperature, and the corresponding area of ​​the disc-shaped wood will be accurately dried by the steam of the corresponding temperature, thereby changing the drying method of the disc-shaped wood in the prior art and solving the technical problem of long drying time.
