Description

Technical Field

[0001] The invention relates to the technical field of wood carbonization devices, and in particular to a device for wood segmented carbonization. Background Art

[0002] Wood carbonization refers to the pyrolysis of wood at a high temperature of 160℃~250℃, which breaks the hydrogen bonds connecting hemicellulose and cellulose inside the wood and degrades the hemicellulose rich in hydrophilic groups, thereby reducing the hygroscopicity of the wood and greatly improving the dimensional stability and performance of the wood. The carbonized wood has prominent texture, warm color, and woody fragrance. Compared with uncarbonized solid wood materials, it has stronger moisture resistance, dimensional stability, and better resistance to mildew and insect infestation. However, the bending and cracking resistance of carbonized wood decreases. When used to make solid wood floors, the floor's bending resistance and flexibility are not good; the color of the wood surface after carbonization deepens, affecting the surface decoration effect and limiting the scope of use of carbonized wood.

[0019] The beneficial effects produced by the present invention include:

[0020] 1. In view of the common defects of wood carbonization in the prior art, the present invention discloses a device for wood segment carbonization, wherein first chambers are arranged at equal intervals inside the chamber of the heating block of the device for wood segment carbonization, and the first chambers and the heating chamber are not connected to each other, but are connected to the main input pipeline and the main output pipeline through branches respectively; during the carbonization treatment, by controlling the flow time of the heat transfer medium in the first chamber and the heating chamber, the carbonization treatment time of the first chamber and the heating chamber corresponding to the wood is different, and the carbonization degree of different areas of the wood is further differentiated, and finally the wood after carbonization treatment has the advantages of carbonized wood and has anti-bending and flexibility;

[0021] 2. The first chamber of the present invention is arranged at the lower part of the heating chamber, and the height of the first chamber is smaller than the height of the heating chamber. When the heat transfer medium no longer flows in the area outside the heating chamber except the first chamber, since the height of the first chamber is smaller than the height of the heating chamber, and the wood is arranged between two adjacent heating blocks during carbonization, the heating area of ​​the heating block for carbonized wood is only the area corresponding to the first chamber, so that the colors of the two sides of the carbonized wood change differently, and the side not in contact with the first chamber has a lighter color, which has better decorative properties and is suitable for more decoration styles, thus broadening the scope of use of carbonized wood;

[0022] 3. The wood segmented carbonization device of the present invention can also be used in wood drying. The lifting assembly is a scissor-type lifting frame, and the operation rhythm of the articulated units is consistent, so that the spacing change of the heating blocks connected to the connecting part can be consistent, so that the wood can be heated evenly, ensuring the stability of the performance of drying the wood;

[0023] 4. The lower part of the outer side of the first track and the second track of the present invention is respectively provided with a buffer groove. When the wood is placed between the heating blocks during the carbonization process, the stacking structure of the heating blocks and the wood needs to be pressurized by the pressurizing unit so that the wood and the heating blocks can fit tightly. During the pressurizing process, the connecting protrusion can move in the buffer groove, so that the heating block can properly adjust itself to adapt to the pressure in the compressed state. The buffer groove prevents the excessive force between the heating block and the connecting part during the pressurizing process, which may damage the device structure.

[0024] 5. The conveying roller on the upper surface of the heating block of the present invention reduces the friction between the wood and the surface of the heating block when the wood is placed on the surface of the heating block, thereby facilitating the placement and removal of the wood.

[0063] The operation method of the wood segmented carbonization device of the present invention when applied to wood carbonization is as follows:

[0064] The wood is arranged on the upper surface of the heating block 21. The heating blocks 21 are arranged on both the upper and lower surfaces of the wood. During the conveying process, the conveying rollers 23 can facilitate the movement of the wood on the upper surface of the heating block 21. The transmission rod 322 is driven by the driving motor 321 to rotate, driving the ends of the first rotating rod A 3151 and the second rotating rod A 3152 connected to the first connecting rod 3133 to move along the first slide groove A and the first slide groove B, thereby driving the first connecting rod 3133 connected to the transmission rod 322 away from the second connecting rod 3134, so that the heating block 21 connected to the connecting portion 314 moves downward.

[0065] Then, a heat transfer medium is introduced into the heating block 21, so that the heat transfer medium flows in the heating chamber 211 and the first chamber 212, and the upper and lower surfaces of the wood are carbonized at the same temperature. After the carbonization treatment is carried out for a period of time, the heat transfer medium is stopped from being introduced into the heating chamber 211, while the heat transfer medium continues to be introduced into the first chamber 212, so that the lower surface of the wood and the area of ​​the upper surface not corresponding to the first chamber 212 stop carbonizing, while the area corresponding to the first chamber 212 continues to carbonize. By controlling the time of the carbonization treatment on the wood surface, different areas on the wood surface are carbonized to different degrees.
