Description

Technical Field

[0001] The utility model relates to the technical field of wood board drying, in particular to a synthetic wood board drying device. Background Art

[0002] Synthetic wood board is a board made of multiple layers of materials, usually three or more layers. Commonly used materials include fiberboard, particleboard, medium-density fiberboard, etc. These materials are combined in a certain proportion and direction to form a whole, and then the whole is pressed into the desired shape by hot pressing or other methods, and finally surface treatment is performed, such as polishing, painting, etc. The price of synthetic wood board is relatively low, so it has been widely used.

[0003] Synthetic wood boards need to be painted on their surfaces during production. If natural drying is adopted, the drying and curing time of the paint surface is long. Existing drying methods are mostly hot air drying and electric heating drying. When the hot air flow of hot air drying acts on the undried paint, it is easy to cause the paint to flow, which in turn causes raised paint to appear on the surface of the synthetic wood boards. Local overheating or uneven heating problems are prone to occur during the electric heating drying process. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model provides a technical solution: a synthetic wood board drying device, comprising a conveying mechanism 1, a drying chamber 2 is arranged on the conveying mechanism 1, a steam inlet 3 is arranged on one side of the drying chamber 2, a steam outlet 4 is arranged on the other side of the drying chamber 2, a steam channel 6 is arranged inside the inner wall of the drying chamber 2, and a plurality of curing lamps 7 are installed on the inner side of the top of the drying chamber 2, such as Figure 1 As shown, the synthetic wood board to be dried is placed with the paint surface facing upward on the conveying mechanism 1, and the synthetic wood board is conveyed by the conveying mechanism 1 to the drying chamber 2, where it is dried inside the drying chamber 2. After drying, the wood board is moved out under the drive of the conveying mechanism 1, thereby realizing continuous drying of multiple groups of wood boards.

[0024] Among them, high-temperature steam enters the steam channel 6 through the steam inlet 3 of the drying chamber 2, and flows inside the steam channel 6. During the flow, the air inside the drying chamber 2 is heated, and the paint surface of the synthetic wood board is heated through air heat transfer to achieve drying of the wood board. The steam after heat exchange is discharged through the steam outlet 4.

[0025] While the wood board is being dried by high-temperature steam, multiple groups of curing lamps 7 are powered on and illuminated to irradiate the painted surface of the wood board to perform a photochemical reaction, thereby accelerating the curing of the paint surface and improving the drying efficiency.

[0026] Steam can transfer heat evenly and the air is heated evenly, avoiding the problems of local overheating and uneven heating during electric heating and drying. There is no large-scale flow of gas during steam heating and drying. Therefore, the paint surface can be cured evenly to form a flat and smooth paint surface.

[0027] A heat conducting plate 8 is provided on the side wall of the steam channel 6. The heat conducting plate 8 plays a role in uniform heat transfer and can improve the uniformity of heating of the wooden board.

[0028] Wherein, a first valve 5 is installed on both the steam inlet 3 and the steam outlet 4. The first valve 5 can be opened and closed. By controlling the opening and closing of the first valve 5, the opening and closing of the steam inlet 3 and the steam outlet 4 are controlled.

[0029] The steam inlet 3 is connected to the steam delivery pipe 11 , and the high-temperature steam enters the steam channel 6 of the drying chamber 2 through the steam delivery pipe 11 .

[0030] The steam outlet 4 is connected to the steam reflux pipe 12 , and the steam after heat exchange refluxes through the steam reflux pipe 12 .

[0031] Among them, condensate drain pipes 9 are provided at the lower parts of both sides of the drying chamber 2, and a second valve 10 is installed on the condensate drain pipe 9. The opening and closing of the condensate drain pipe 9 are controlled by controlling the opening and closing of the second valve 10. In the process of continuous flow of steam in the steam channel 6, a certain amount of condensate will be generated, and the condensate will be discharged through the condensate drain pipe 9.

[0032] Baffles 13 are installed at both the front and rear ends of the drying chamber 2, and the baffles 13 and the drying chamber 2 are fixed by screws.

[0033] Among them, an aisle is formed between the lower part of the baffle 13 and the conveying mechanism 1. The baffle 13 blocks the front and rear ends of the drying chamber 2 to reduce heat loss. The wooden boards to be dried enter the drying chamber 2 through the lower aisle. After drying, they are moved out of the drying chamber 2 through the lower aisle.

[0034] The baffle 13 is detachably connected to the drying chamber 2, and the position of the baffle 13 relative to the drying chamber 2 is adjustable. The size of the aisle can be adjusted accordingly according to the thickness of the synthetic wood board, so that the synthetic wood board can be moved in and out normally.

[0035] Among them, the conveying mechanism 1 includes a frame 14, and a plurality of groups of rollers 15 are installed on the inner side of the frame 14. The plurality of groups of rollers 15 are connected through a synchronous wheel and synchronous belt assembly. A motor 16 is installed on the outer side of the frame 14. When the motor 16 is working, it drives the plurality of groups of rollers 15 to rotate synchronously. The rotating plurality of groups of rollers 15 convert the rotational force into a linear driving force, and the synthetic wood board is driven by the linear driving force.

[0036] Working principle: When in use, the size of the aisle below the baffle 13 is adjusted accordingly according to the thickness of the synthetic wood board, so that the synthetic wood board can be moved in and out normally, and the synthetic wood board to be dried is placed on the conveying mechanism 1 with the paint surface facing up, and the synthetic wood board is conveyed by the conveying mechanism 1, and multiple sets of composite wood boards are conveyed to the drying chamber 2 in turn, and dried inside the drying chamber 2. During drying, high-temperature steam enters the steam channel 6 of the drying chamber 2 through the steam conveying pipe 11 and flows inside the steam channel 6. During the flow, the air inside the drying chamber 2 is heated, and the paint surface of the synthetic wood board is heated by air heat transfer to achieve drying of the wood board. The steam after heat exchange is refluxed through the steam reflux pipe 12. At the same time, multiple sets of curing lamps 7 are powered on and lighted, irradiating the paint surface of the wood board to perform photochemical reaction, accelerate the curing of the paint surface, and improve drying efficiency. After drying, the wood board is moved out under the drive of the conveying mechanism 1, and the above actions are repeated to achieve continuous drying of multiple sets of composite wood boards. The condensed water generated during the steam flow is discharged through the condensed water discharge pipe 9.
