Description

Technical Field

[0001] The invention relates to the technical field of wood heat treatment, in particular to a heat treatment device for wood structure processing. Background Art

[0002] Wood heat treatment is a technology that improves the various properties of wood by subjecting it to a short-term pyrolysis treatment in a protective gas environment. This treatment can improve the dimensional stability of wood, eliminate or reduce the stress inside the wood, and improve the durability and color of wood. Specifically, the chemical changes in wood after heat treatment cause hemicellulose, especially polysaccharide aldehydes, to be converted into weakly hygroscopic monomers, and the hydroxyl groups in the cellulose molecular chain interact to form hydrogen bonds, thereby reducing the hygroscopicity of wood. However, when treating wood, cracking, deformation and natural problems may occur. In view of this, we are making technological innovations based on existing manufacturing equipment.

[0003] The application number retrieved is: CN201510315019.X, an energy-saving wood heat treatment kiln and wood heat treatment method that can save energy, which is to put the wood into a left chamber and a right chamber respectively, first start the left chamber to start the drying process, when the drying process of the left chamber is completed and enters the heating process, start the right chamber to start the drying process, and open the baffle so that part of the hot and humid air in the left chamber can enter the right chamber through the connecting hole; when the left chamber is in the cooling process, the right chamber is in the heating process or the insulation process, and the baffle is opened so that the hot and humid air in the left chamber can enter the right chamber through the connecting hole.

[0004] However, the existing wood heat treatment equipment still has certain defects in actual use: when heat treating the wood, due to the form of the wood itself, the moisture in the wood is separated, which leads to the loss of moisture in the wood, and causes problems such as wood cracking and deformation. At the same time, during the heat treatment process, if there is an abnormality between the wood and the oxygen inside the heat treatment equipment, the wood is very likely to spontaneously combust. For this reason, we propose a heat treatment device for wood structure processing. Summary of the invention

At this time, the sealing door 4 can reciprocate through the rollers 38, while reducing the friction during the movement of the sealing door 4. The insulation baffle 8 installed inside the heat treatment room 1 can prevent heat dissipation.

[0036] A door closing assembly 39 is provided on the side of the sealing baffle 5 away from the heat treatment room 1, and the door closing assembly 39 includes a mounting ring 34, a rotating rod 35, a rotating ring 36 and a locking rod 37, and a rotating rod 35 is provided on the side of the mounting ring 34 away from the heat treatment room 1, and a rotating ring 36 is installed on the side of the rotating rod 35 away from the mounting ring 34 through bolts, and a locking rod 37 is provided above the mounting ring 34, and the sealing assembly drives the rotating rod 35 to squeeze the sealing door 4 through the rotating ring 36, so that the sealing door 4 is continuously fitted with the entrance of the heat treatment room 1, thereby reducing the appearance of gaps to facilitate the circulation of water vapor inside the heat treatment room 1.

[0037] In summary, if Figure 1 - Figure 8As shown, the heat treatment device for wood structure processing, when in use, by rotating the rotating ring 36 of the closing door assembly 39, the rotating ring 36 drives the rotating rod 35 to loosen the restriction on the sealing door 4, and then the sealing door 4 is pushed to move along the sealing baffle 5, so that the sealing door 4 moves outward, and the wood is stacked and transported into the heat treatment room through the slide rail. After the wood is placed, the sealing door 4 is reset, the closing door assembly 39 is reversed, and the sealing door 4 is locked, so that the sealing door 4 is fitted with the heat treatment room 1.

At this time, the spray head is turned on to continuously spray water vapor into the heat treatment room 1. At this time, the temperature inside the heat treatment room 1 is continuously raised, and the humidity inside the heat treatment room 1 is maintained. Therefore, heat is continuously accumulated inside the heat treatment room 1. At this time, the heat acts on the outer surface of the wood, causing the water on the outer surface of the wood to evaporate into water molecules at high temperature, causing the water inside the wood to continuously sublimate. At this time, due to the continuous increase in the temperature inside the heat treatment room 1, and due to the display of water vapor, the wood in the heat treatment room 1 is The wood inside the room 1 will not come into contact with the oxygen in the air and will not naturally show. When the temperature and humidity inside the heat treatment room 1 change, the temperature and humidity of the heat treatment room 1 are detected by the temperature sensor 24 and the humidity sensor 25 of the humidity control exhaust system 11. When it is confirmed that the humidity needs to be processed, the water vapor is adsorbed by the condensation box 26, thereby reducing the humidity inside the heat treatment room 1. At the same time, the high temperature inside the heat treatment room 1 cooperates with the air circulation system 17, so that the heat is continuously circulated inside the heat treatment room, thereby facilitating the hot wood to contact the heat evenly. When the heat treatment of the wood is completed, the remaining heat is converted into electrical energy through the electric heat conversion equipment inside the heat recovery box 6, so as to facilitate the recovery of the heat recovery box 6 for recovering the waste heat generated during the drying process, improve energy utilization efficiency, and reduce energy consumption.
