Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically to a single-board drum drying line equipment. Background Technology

[0002] Veneer, also known as thin wood veneer or single-layer board, is a thin sheet of wood produced by rotary cutting or slicing logs. Veneer has a wide range of applications in wood processing and furniture manufacturing.

[0003] Drying wood panels is not only a necessary step to improve product quality and performance, but it also effectively prevents wood deformation, decay, and insect infestation, optimizes processing performance, saves transportation and storage costs, and meets industry standards and regulations. Therefore, drying treatment is of great significance in wood processing and use.

[0004] There are several existing methods for drying wood panels: 1. Natural air drying: Wet wood or panels are placed in a well-ventilated environment and gradually dried by natural wind and sunlight. This method is time-consuming, highly dependent on weather and environmental conditions, and susceptible to insect and mold infestations. It is suitable for small-batch wood processing where high drying speed is not critical. 2. Vacuum drying: Moisture evaporation is accelerated by reducing air pressure in a vacuum environment. Vacuum drying typically requires specialized equipment. The equipment is expensive and complex to operate. It is suitable for high-end furniture manufacturing and the drying of precious woods. 3. Microwave drying: Microwaves heat the internal moisture of the wood, causing it to evaporate rapidly. Microwave drying equipment typically includes a microwave generator and a drying chamber. The equipment is expensive and energy-intensive. It is suitable for small-batch wood processing requiring rapid drying. 4. Infrared drying: Infrared radiation heats the surface of the wood, causing moisture to migrate from the surface to the interior and evaporate. Infrared drying equipment typically includes infrared lamps and control devices. The equipment is expensive and not suitable for thick boards and large-sized wood. It is suitable for the rapid drying of thin boards and small-sized wood. 5. High-frequency drying. High-frequency electromagnetic fields are used to heat the moisture inside the wood, causing it to evaporate rapidly. High-frequency drying equipment typically includes a high-frequency generator and a drying chamber. The equipment is relatively expensive and complex to operate. It is suitable for small-batch wood processing requiring rapid drying. Utility Model Content

[0028] Reference Figures 1-5 A single-layer veneer roller drying line includes a machine body 1, on which at least one roller conveyor 2 is installed. To provide the quantity and efficiency of drying veneers each time, two or more sets of roller conveyors 2 can be arranged side by side. The roller conveyor 2 is used to transport veneers from one end to the other end of the machine body 1, that is, from the feed end to the discharge end. The roller conveyor 2 includes roller assemblies 200 arranged side by side, and the space between the two sets of roller assemblies 200 is used for the passage of veneers. When the two sets of roller assemblies 200 rotate, they drive the veneers through the space between the two sets of roller assemblies 200. Each roller assembly 200 is driven to rotate synchronously by a conveyor motor. A drying device 4 is also installed on the machine body 1. The drying device 4 includes an upper air duct 400 located at the upper end of the machine body 1, a drying chamber 401 located at the lower end of the upper air duct 400, and side air ducts 402 provided on both sides of the drying chamber 401. A radiator is installed in the upper air duct 400. 403 and fan 404, fan 404 is driven by fan motor 405 installed outside the machine body 1; air blowing pipes 406 are installed side by side vertically inside the drying chamber 401, and multiple air blowing holes 4060 are opened on the side of the air blowing pipes 406 facing the veneer for blowing hot air to the veneer for heating and drying; it also includes a dehumidification port 3 installed on the top of the machine body 1, which is connected to the upper air duct 400; during the drying process, the wood will release a large amount of moisture, and the dehumidification port 3 can effectively remove this moisture from the drying chamber 401, reduce the indoor humidity, and thus accelerate the drying speed of the wood. By adjusting the dehumidification port 3, the temperature and humidity in the drying chamber can be controlled to ensure that the wood dries under the best conditions and avoids the drying speed being too fast or too slow. The dehumidification port 3 plays a multifaceted role in the board drying production line, which can not only improve drying efficiency and product quality, but also protect equipment, reduce energy consumption, and have a positive impact on environmental protection and safety.

[0029] In use, the veneer is conveyed into the machine body 1 via the roller conveyor 2. (Refer to...) Figure 3 Steam generated by a boiler located outside the machine body 1 is transported to radiator 403 through pipes. Radiator 403 generates heat in the upper air duct 400. Fan 404 blows the heat into one side of the air duct 402. The hot air is then blown onto the front and back of the veneer through parallel air ducts 406, heating the veneer and causing moisture to evaporate. The hot air is then blown into the other side of the air duct 402 through the space between the two air ducts 406, and finally returns to the upper air duct 400. The heat generated by radiator 403 is circulated in the drying chamber 401 by fan 404. Exhaust port 3 removes the moisture evaporated from the veneer. The drum drying line adopts a continuous drying design, which can operate 24 hours a day without interruption and has a large single processing capacity. Through hot air circulation, the heat utilization rate is high, which can reduce energy costs.

[0030] In some embodiments, the air duct 406 includes an inclined surface 4061 and a flat surface 4062. The inclined surface 4061 is used to optimize and improve the air velocity, and multiple air holes 4060 are evenly distributed on the flat surface 4062, so that the single board is heated more fully and evenly, which can improve the drying efficiency.

[0031] In some embodiments, radiator 403 is a steam radiator, a device that utilizes the high-temperature characteristics of steam to transfer heat to the surrounding environment through heat exchange. It typically consists of one or more fins and internal pipes for transporting steam. Steam is usually generated by a boiler, which heats water to create high-temperature, high-pressure steam. The steam generated by the boiler is transported to radiator 403 through pipes. When the steam enters the pipes of radiator 403, due to the temperature difference between the surface of radiator 403 and the surrounding air or liquid, heat is transferred to the surrounding medium through the fins. During the heat dissipation process, the steam gradually condenses into water, releasing a large amount of latent heat. The condensed water returns to the boiler through a return water pipe, is reheated into steam, and forms a circulation system. It has advantages such as high-efficiency heat transfer, stability and reliability, energy saving, and easy maintenance. Fan 404 is a centrifugal fan, a device that uses a rotating impeller to draw in and discharge gas, and has advantages such as high efficiency, low noise, easy maintenance, and strong adaptability. An opening and closing plate 301 is installed inside the vent 3 to open and close the vent 3, thereby adjusting the humidity inside the drying chamber 401.

[0032] In some embodiments, each roller assembly 200 includes a plurality of rollers 2001 mounted side by side along the length of the machine body 1, which can make the plate move more smoothly, and the rollers 2001 can be driven by a chain.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
