Description

Technical Field

[0001] The utility model relates to the technical field of wood board pretreatment, in particular to a wood board heating device with a preheating function. Background Art

[0002] Heating wood, also known as heat treatment, is a process for improving the properties of wood. This treatment can improve the dimensional stability of wood and eliminate or reduce the internal stress of wood, because hemicellulose, especially polysaccharide aldehydes, undergoes chemical changes and becomes a weakly hygroscopic monomer; the hydroxyl groups in the cellulose molecular chain combine with each other to form hydrogen bonds. Heat treatment can also improve the anti-corrosion properties of wood, because the change in wood components cuts off the source of nutrients required for fungi to survive, and the reduction in moisture content inhibits fungi growth, thereby improving corrosion resistance. In addition, heat treatment can also change the color of wood, mainly due to changes in compounds, the degradation of hemicellulose, lignin, and certain extractable compounds. However, when heating the wood board for pretreatment, the temperature concentration effect often causes the temperature of the pretreated wood board itself to be different, resulting in the cracking of some wood boards. Therefore, a wood board heating device with a preheating function is required.

[0003] The application number retrieved is: CN202110818865.9, a pretreatment mechanism for wood processing, an electric heating box and a first blower are provided at the top of the box body, the air inlet of the first blower is connected to the electric heating box, and the air outlet of the first blower is connected to a ventilation pipe, which is fixedly connected to the inner rear wall of the drying bin.

[0004] However, the existing wood board pretreatment still has certain defects in actual use: when pretreating the wood board, the temperature in the furnace cannot be evenly transferred, which causes the temperature to be in contact with the wood board. The temperature of a certain node of the wood is too high, and the temperature of other areas cannot keep up with the corresponding temperature changes in time, resulting in the water evaporation rate of the wood board in the area with too high temperature being higher than that of other parts, which causes the wood board to dry and crack. For this reason, we propose a wood board heating device with a preheating function. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a wooden board heating device with a preheating function, which aims to improve the problem that when the wooden board is pre-treated, the temperature in the furnace cannot be evenly transferred, resulting in the temperature being too high when a certain node of the wood comes into contact with the wooden board, and the temperature of other areas cannot keep up with the corresponding temperature changes in time, resulting in the water evaporation rate of the wooden board in the area with too high temperature being higher than that of other parts, thereby causing the wooden board to dry out and crack.

At this time, the central heating chamber 13 cooperates with the first heating chamber 19 and the second heating chamber 20, and then the wooden board is placed in the center of the first heating chamber 19 and the central heating chamber 13 and the center of the central heating chamber 13 and the second heating chamber 20 in turn. At this time, the wooden board is heated again, which can make the wooden board obtain uniform temperature release, thereby avoiding the occurrence of excessive temperature in a certain area of ​​the wooden board, which causes the wooden board to dry and crack. At this time, the power supply 26 transmits current into the heating wire 24 to form a short circuit, so that the heating wire 24 heats up, and the insulation board 25 inside the central heating chamber 13 is used to block the reverse osmosis of heat, so that the radiation range of heat diffuses to one side.

At this time, the hot water source enters the regulating valve 5 along the first water inlet pipe 3, and the flow direction of the water source is controlled by the regulating valve 5, so that the hot water source enters the second water outlet pipe 6, so that the position of the hot water source for transporting to the inside of the heating furnace 1 is different.

[0024] The bottom end of the connecting head 8 is installed with a connecting pipe 16 by bolts, and a spray head 17 is provided on the side of the connecting pipe 16 away from the connecting head 8, and the second water outlet pipe 6 sprays the hot water source through the spray head 17 installed on the connecting pipe 16, so as to maintain the humidity of the space inside the heating furnace 1 and the wooden board, thereby always maintaining the humidity of the wooden board during the pretreatment process, thereby avoiding the problem of cracking of the wooden board.

[0025] A ventilation component 15 is provided on the side of the spray head 17 away from the central heating chamber 13, and the ventilation component 15 includes an outer shell 27, a support base 22, a fan 23 and an air inlet 1501, and a support base 22 is installed above the inner wall of the outer shell 27, and a fan 23 is installed above the support base 22, and an air inlet 1501 is provided on the side of the fan 23 away from the spray head 17, and a temperature detection box 14 is provided below the ventilation component 15, and the ventilation component 15 sprays water from the hot water source at the spray head 17, and the fan 23 blows wind into the heating furnace 1, thereby blowing the water mist converted into steam by the water droplets of the hot water source inside the heating furnace 1, so that the water mist is continuously circulated in the circulation channel 18 inside the heating furnace 1, so that the water vapor is continuously in contact with the wooden board, so that the water vapor obtained on the outer surface of the wooden board is uniform.

The circulating air chamber 21 cooperates with the ventilation component 15 to circumvent the direction of temperature flow inside the heating furnace 1, so that the temperature contacted by the wooden board is constantly changing, thereby avoiding cracking caused by excessive temperature at a certain node of the wooden board.

[0027] In summary, the utility model uses the heating furnace 1 and the central heating chamber 13, and the sealing plate 10 connected by the mounting bracket 9, so that the sealing plate 10 is driven to open, and the wooden boards are stacked and evenly placed inside the internal space of the heating furnace 1. At this time, the sealing plate 10 is closed by the mounting bracket 9, and the heating wire 24 inside the first heating chamber 19 and the heating wire 24 near the first heating chamber 19 inside the central heating chamber 13 are driven to generate heat, and the heating wire 24 inside the second heating chamber 20 and the heating wire 24 near the second heating chamber 20 inside the central heating chamber 13 are driven to generate heat, so that the temperature inside the heating furnace 1 is increased.
