Description

Technical Field

[0001] The present invention relates to the technical field of wood drying, and particularly relates to a wood drying device. Background Art

[0002] Wood drying is to prevent wood from rotting or being damaged by pests. Before drying the wood, it is necessary to cut the wood raw materials so that the wood raw materials can be cut into stick-shaped wood, disc-shaped wood, etc.

[0003] In the prior art, in order to facilitate the drying treatment of wood, usually multiple pieces of wood are placed in a drying chamber in a stacked manner, and multiple temperature and humidity sensors in the drying chamber and a transmission pipe for transmitting steam are used to dry the wood. At the same time, in order to prevent the wood from cracking due to excessive temperature, during the drying process, steam with different temperatures and humidities is usually repeatedly introduced to repeatedly dry the wood, so that the drying degree of the side and the middle of the wood can meet the standards.

[0004] However, due to the characteristics of the disc-shaped wood itself, that is, the density in the middle of the disc-shaped wood is much greater than that on the outside, when the steam conducts heat, it cannot be transmitted to the middle of the disc-shaped wood in a short time, resulting in a long drying time for the disc-shaped wood. Summary of the Invention

[0019] For ease of understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are shown in the drawings.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] Embodiment Please refer to Figures 1 to 9 , which shows a wood drying device in an embodiment of the present invention, including a drying box 100, a plurality of material racks 200 and a plurality of drying components 300. The plurality of material racks 200 are spaced within the drying box 100, and a drying component 300 is provided on each of the opposite sides of each material rack 200. The material rack 200 is used to carry disk - shaped wood materials; The drying assembly 300 includes a steam container having a plurality of annular chambers, a plurality of steam conduction switches provided on each annular chamber, at least one spiral guide rail, at least one steam spray head slidably connected within the spiral guide rail, and a driving component for driving the steam spray head to intermittently slide along the guiding path of the spiral guide rail; The guiding path of the spiral guide rail extends throughout the plurality of annular chambers, such that the plurality of steam conduction switches on each annular chamber are all located within the guiding path of the spiral guide rail, so that when the steam spray head intermittently slides within the spiral guide rail, the steam spray head conducts with the corresponding steam conduction switch to transfer the steam in the corresponding annular chamber into the steam spray head; Among them, the plurality of annular chambers are sleeved with each other, each annular chamber is used to accommodate steam of a certain temperature, and the steam temperatures in the plurality of annular chambers increase sequentially from the outer annular chamber to the middle annular chamber.

[0023] It should be noted that in actual situations, since the density in the middle of the disk-shaped wood is much greater than that on the outside, during the drying process, it is necessary to precisely dry different regions of the disk-shaped wood according to their densities to reduce the drying time of the disk-shaped wood.

[0024] In specific implementation, multiple disk-shaped woods can be placed using the multiple material racks 200 in this example, and a drying assembly 300 is provided on each of the opposite sides of each material rack 200. When drying multiple disk-shaped woods, the driving component in the drying assembly 300 can be used to drive the steam spray head to intermittently slide along the guiding path of the spiral guide rail, so that the steam spray head can perform a spiral intermittent movement from the outside to the inside or from the inside to the outside along the shape of the disk-shaped wood. During the movement, the steam spray head can be aligned with the corresponding steam conduction switch, so that the steam in the annular chamber corresponding to the steam conduction switch can be transferred into the steam spray head, and the steam spray head outputs steam of the corresponding temperature to the surface of the disk-shaped wood to achieve the purpose of drying the disk-shaped wood. At the same time, for precise drying according to the densities of different regions of the disk-shaped wood, in this example, the guiding path of the spiral guide rail extends throughout the plurality of annular chambers, each annular chamber is used to accommodate steam of a certain temperature, and the steam temperatures in the plurality of annular chambers increase sequentially from the outer annular chamber to the middle annular chamber. By accommodating different temperatures of steam in different annular chambers, when the steam spray head moves to the corresponding region of the disk-shaped wood, the steam spray head will conduct with the annular chamber of the corresponding temperature, and the corresponding region of the disk-shaped wood will be precisely dried by the steam of the corresponding temperature, thereby changing the drying method of the disk-shaped wood in the prior art and solving the technical problem of long drying time.

[0025] For further understanding of this case, please refer to Figure 7As shown, the multiple annular chambers shown in this example may 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 sleeved 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. Among them, the first temperature is greater than the second temperature, and the second temperature is greater than the third temperature.

[0026] Specifically, the temperature of the steam accommodated in the first annular chamber 330 is the highest, the temperature of the steam accommodated in the third annular chamber 350 is the lowest, and the temperature of the steam accommodated in the second annular chamber 340 is between the highest temperature and the lowest temperature. That is to say, using the steam in the first annular chamber 330 at the highest temperature, when the steam nozzle moves to the steam conduction switch corresponding to the first annular chamber 330, the steam at the highest temperature in the first annular chamber 330 will directly act on the center of the disc-shaped wood, and the steam at the highest temperature is used to dry the central area of the disc-shaped wood. It should be noted that the central area of the disc-shaped wood is the area with the highest density, and the steam at the highest temperature can be used to 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 at the lowest temperature in the third annular chamber 350 will directly act on the outer area of the disc-shaped wood, and the steam at the lowest temperature is used to dry the outer area of the disc-shaped wood. It should be noted that the outer area of the disc-shaped wood is the area with the lowest density. That is to say, precise drying can be carried out according to the density of different areas of the disc-shaped wood, which can greatly reduce the drying time of the disc-shaped wood.

[0027] It should be noted that in some initial states, since the disc-shaped wood itself is at room temperature, to avoid the problem of the disc-shaped wood cracking, 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 use the preheating temperature to preheat the disc-shaped wood. And because the densities of different areas of the disc-shaped wood are different, during the preheating process, the steam temperature can also be increased sequentially 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 reach an effective preheating effect in a short time.

[0028] In addition, for facilitating 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 transfer pipes 370, a plurality of second transfer pipes 371, a plurality of third transfer pipes 372, and a plurality of steam pumps 380. Each steam pump 380 is used to output steam at a certain temperature. One end of each of the plurality of first transfer pipes 370 is respectively communicated with the plurality of first annular chambers 330, and the other ends of the plurality of first transfer pipes 370 are communicated with each other and connected to the corresponding steam pump 380 to transmit steam at the first temperature into the plurality of first annular chambers 330. One end of each of the plurality of second transfer pipes 371 is respectively communicated with the plurality of second annular chambers 340, and the other ends of the plurality of second transfer pipes 371 are communicated with each other and connected to the corresponding steam pump 380 to transmit steam at the second temperature into the plurality of second annular chambers 340. One end of each of the plurality of third transfer pipes 372 is respectively communicated with the plurality of third annular chambers 350, and the other ends of the plurality of third transfer pipes 372 are communicated with each other and connected to the corresponding steam pump 380 to transmit steam at the third temperature into the plurality of third annular chambers 350.

[0029] Specifically, please refer to again Figure 7 As shown, there may be three steam pumps 380. For example, the first steam pump 380 is used to output steam at the first temperature, the second steam pump 380 is used to output steam at the second temperature, and the third steam pump 380 is used to output steam at the third temperature. Three steam pumps 380 can output steam at three temperatures and transmit the steam at the three temperatures to the plurality of first annular chambers 330, the plurality of second annular chambers 340, and the plurality of third annular chambers 350 respectively.

[0030] It should be noted that in this embodiment, the first annular chamber 330, the second annular chamber 340, and the third annular chamber 350 do not limit the number of annular chambers. Other numbers of annular chambers can also be adopted. When other numbers of annular chambers are adopted, the number of corresponding transfer pipes and the number of steam pumps 380 are set in one-to-one correspondence with the number of annular chambers. It should be noted that the transfer pipes are the general terms of the above-mentioned first transfer pipes 370, second transfer pipes 371, and third transfer pipes 372, and no special description is made here.

[0031] In addition, it should be noted that for facilitating the driving of the steam nozzle to move, in this embodiment, the driving component includes a driving member having at least one output shaft and at least one rotating member having a guiding groove. The driving member is arranged at the center of the steam accommodating member, and the output shaft is connected to the rotating member to drive the rotating member to rotate. Among them, part of the steam nozzle is slidably connected in the guiding groove.

[0032] Specifically, the driving member shown in this embodiment can adopt a motor in the prior art to drive the rotating member to rotate, and the length of the rotating member can be equal to the radius of the steam containing member, so that when the rotating member rotates, it can fully cover the surface of the disc-shaped wood. And when the rotating member rotates, by means of the arrangement of the guiding grooves, the rotating member can apply a thrust to the steam nozzle, so that the steam nozzle moves in the spiral guide rail and relatively slides in the guiding groove.

[0033] 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 a plurality of annular heat insulation plates in the steam containing member. By virtue of the heat insulation property of the heat insulation plates, 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 the heat insulation plates belong to the conventional prior art in this field, so no special description will be made here.

[0034] In addition, to improve the practicability of the drying device in the embodiment, in this embodiment, a plurality of drying assemblies 300 include a plurality of drying assemblies a310 arranged in the middle of the drying box 100 and two drying assemblies b320 arranged at the top and bottom of the drying box 100.

[0035] Please refer to Figure 4 and Figure 5 As shown, the drying assembly a310 includes a steam containing member a311 having a plurality of annular chambers, two spiral guide rails a312, two steam nozzles a313, two groups of a plurality of steam conduction switches a314 and a driving member a315. The driving member a315 includes a driving member a3152 having two output shafts a3151 and two rotating members a3154 having guiding grooves a3153. It should be noted that the plurality of annular chambers in the steam containing member a311 are the above-mentioned first annular chamber 330, second annular chamber 340 and third annular chamber 350. Specifically, please refer to Figure 7 As shown; Among them, one spiral guide rail a312, one steam nozzle a313, one group of a plurality of steam conduction switches a314, one output shaft a3151 and one rotating member a3154 are arranged on one side of the steam containing member a311; The other spiral guide rail a312, the other steam nozzle a313, the other group of a plurality of steam conduction switches a314, the other output shaft a3151 and the other rotating member a3154 are arranged on the other side of the steam containing member a311.

[0036] Please refer to Figure 6As shown, the drying component b320 includes a steam container b321 with multiple annular chambers, a spiral guide rail b322, a steam nozzle b323, multiple steam conduction switches b324, and a driving component b325. The driving component b325 includes a driver b3252 with an output shaft b3251 and a rotating member b3254 with a guiding groove b3253. It should be noted that the multiple annular chambers in the steam container b321 are the same as those in the steam container a311. Given that the structures of the multiple annular chambers in the steam container b321 and the steam container a311 are the same, in this embodiment, Figure 7 the structure shown in is used to represent the multiple annular chambers in the steam container a311 and the multiple annular chambers in the steam container b321; Among them, the spiral guide rail b322, the steam nozzle b323, the multiple steam conduction switches b324, the output shaft b3251, and the rotating member b3254 are arranged on one side of the steam container b321 opposite to an adjacent steam container a311.

[0037] To facilitate the understanding of the drying process of the disk-shaped wood by the above-mentioned multiple drying components a310 and the two drying components b320, three disk-shaped woods are used for illustration here, namely the first disk-shaped wood, the second disk-shaped wood, and the third disk-shaped wood. The first disk-shaped wood is located at the top of the drying box 100, the second disk-shaped wood is located in the middle of the drying box 100, and the third disk-shaped wood is located at the bottom of the drying box 100. And there are two drying components a310, which are located in the middle of the drying box 100.

[0038] Please refer to 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 component b320 at the top of the drying box 100 can dry the upper surface of the first disk-shaped wood. Subsequently, the first drying component a310 dries the lower surface of the first disk-shaped wood. And since in the drying component a310, the driver a3152 has two output shafts a3151, the two output shafts a3151 are used to drive the two rotating members a3154 to rotate respectively. When the two rotating members a3154 drive the two steam nozzles a313 to move, each of the two steam nozzles a313 has a corresponding steam conduction switch a314. That is to say, the first drying component a310 can dry the lower surface of the first disk-shaped wood and the upper surface of the second disk-shaped wood. Similarly, the second drying component a310 can dry the lower surface of the second disk-shaped wood and the upper surface of the third disk-shaped wood. Finally, the second drying component b320 can dry the lower surface of the third disk-shaped wood.

[0039] It should be noted that in the drying component a310, the driving member a3152 can adopt a dual-axis motor in the prior art, and in the drying component b320, the driving member b3252 can adopt a motor with one output shaft in the prior art. Moreover, there is only one steam accommodating member a311 with a multi-annular chamber in the drying component a310. By using one steam accommodating member a311, steam can be provided to two steam nozzles a313, thereby reducing the number of steam accommodating members a311 arranged and effectively reducing the manufacturing cost of the device.

[0040] Furthermore, in some preferred embodiments, one of the two steam nozzles a313 in the drying component a310 is arranged in the central region of a spiral guide rail a312 in the initial state, and the other of the two steam nozzles is arranged in the outer region of another spiral guide rail a312 in the initial state. Among them, the two spiral guide rails a312 are symmetrically arranged. By limiting the initial positions of the two steam nozzles a313, when the two steam nozzles a313 output steam simultaneously, it can ensure that there is enough steam output to the surface of the disc-shaped wood. For example, when the first steam nozzle a313 outputs steam, it will directly obtain the steam in the first annular chamber 330, and when the second steam nozzle a313 outputs steam, it will directly obtain the steam in the third annular chamber 350. Since the steam in the first annular chamber 330 is separated from the steam in the second annular chamber 340, it is ensured that a single steam nozzle a313 obtains the steam in a single annular chamber. It should be noted that to prevent the two steam nozzles a313 from sharing 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 two disc-shaped woods respectively.

[0041] It should be noted that the steam accommodating member b321 in the drying component b320 can also be arranged in the same way as the two steam accommodating members a311 in the above-mentioned drying component a310. For example, in the initial state, if the steam nozzle a313 is arranged in the central region of the steam accommodating member a311, the corresponding steam accommodating member b321 is arranged in the outer region of the steam accommodating member b321.

[0042] In addition, to ensure that steam can be transmitted into the steam nozzle a313 and the steam nozzle b323, in this example, the structures of the steam conduction switches a314 and b324 are the same. Please refer to Figure 8 As shown, the specific structures of the steam conduction switch a314 and the steam conduction switch b324 include two N-pole magnetic discs 360 and an S-pole magnetic disc 361. It should be noted that in Figure 8Take the steam nozzle a313 as an example for illustration; 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; Wherein, the S-pole magnetic disk 361 is arranged in the annular chamber and magnetically connected to the corresponding N-pole magnetic disk 360, so as to seal the steam in the annular chamber; When the steam nozzle moves to face the steam conduction switch, the two N-pole magnetic disks 360 repel each other, so that the steam in the annular chamber is transmitted into the steam nozzle. And the steam conduction switch further includes a plurality of covers 362 having transmission through holes, and the covers 362 are sleeved outside the corresponding N-pole magnetic disk 360.

[0043] For details, please refer to Figure 8 and Figure 9 As shown, in this embodiment, by using the cover 362, it is possible to prevent an N-pole magnetic disk 360 from falling into the interior of the annular chamber. To achieve the transmission of gas into the interior of the steam nozzle, during the intermittent movement of the steam nozzle, the two N-pole magnetic disks 360 can be made to face each other. By the mutual repulsion of the two N-pole magnetic disks 360, a hole is formed in the annular chamber. At this time, the steam located in the annular chamber will be directly transmitted into the steam nozzle. When it is necessary to seal the annular chamber, the steam nozzle will move intermittently again, so that the two N-pole magnetic disks 360 are separated, 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 process of the annular chamber.

[0044] It should be noted that a sealing gasket can be arranged between the N-pole magnetic disk 360 and the S-pole magnetic disk 361 arranged in the annular chamber to ensure the sealing performance of the annular chamber. And the magnetic attraction force between the N-pole magnetic disk 360 and the S-pole magnetic disk 361 arranged in the annular chamber can be artificially interfered through the prior art, so that the magnetic attraction force between the N-pole magnetic disk 360 and the S-pole magnetic disk 361 is less than the repulsive force between the two N-pole magnetic disks 360. And 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 this cavity. Since the steam nozzle belongs to the conventional technology in this field, no special description will be made here.

[0045] In summary, a wood drying device provided by an embodiment of the present invention arranges a plurality of material racks 200 and a plurality of drying components 300 in a drying box 100. When drying a plurality of disc-shaped wood materials, the driving component in the drying component 300 can drive the steam nozzle to intermittently slide along the guiding path of the spiral guide rail, so that the steam nozzle can move spirally and intermittently from the outside to the inside or from the inside to the outside along the shape of the disc-shaped wood material. During the moving process, the steam nozzle can be directly opposite to 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 outputs steam at a corresponding temperature to the surface of the disc-shaped wood material to achieve the purpose of drying the disc-shaped wood material. At the same time, for precise drying according to the density of different regions of the disc-shaped wood material, in the present invention, the guiding path of the spiral guide rail covers a plurality of annular chambers, each annular chamber is used to accommodate steam at a certain temperature, and the steam temperatures in the plurality of annular chambers increase sequentially from the outer annular chamber to the middle annular chamber. By accommodating steam at different temperatures in different annular chambers, when the steam nozzle moves to the corresponding region of the disc-shaped wood material, the steam nozzle will be conducted with the annular chamber at the corresponding temperature, and the corresponding region of the disc-shaped wood material will be precisely dried by the steam at the corresponding temperature, thereby changing the drying method of the disc-shaped wood material in the prior art and solving the technical problem of long drying time.
