Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vertical dryers, specifically to a vertical dryer for processing multi-layer board wood products. Background Technology
[0002] Wood plays a vital role in human life. To improve the utilization rate and performance of wood, it is made into multi-layer boards. Multi-layer boards are three-layer or multi-layer board materials made by rotary cutting wood logs into veneers or slicing wood squares into thin sheets and then gluing them together with adhesives. To improve production efficiency, manufacturers usually use drying equipment to dry the produced multi-layer boards to prevent the glue from not solidifying and causing cracking.
[0003] Existing wood board drying technology involves stacking wood boards in a drying chamber and drying them with charcoal or hot air. However, when stacking wood boards in large quantities for drying, the small gaps between the boards make it difficult for hot air to enter some parts of the boards, easily causing uneven heating, cracking, damaging the properties of the boards, and affecting their quality. Stacking the boards also leads to inconsistent heating of each layer, affecting the drying effect. Therefore, to ensure the drying effect, the drying time needs to be extended, increasing both the drying time and energy consumption.
[0004] Therefore, it is necessary to provide a vertical drying machine for processing multi-layer board wood products to solve the above-mentioned technical problems. Utility Model Content

[0035] refer to Figures 1 to 7 This utility model provides a vertical drying machine for processing multi-layer board wood products, comprising: a machine body 1, the side of the machine body 1 having an open structure, a protective door 2 hinged to the side of the machine body 1, multiple U-shaped connecting grooves 12 on the inner surface of the machine body 1, multiple air outlets 13 on the side of the horizontal part of the connecting groove 12, the two vertical parts of the connecting groove 12 being slidably connected to the two sides of the placement plate 18, multiple drying holes 19 on the top of the placement plate 18, the drying holes 19 being connected to multiple air inlets through channels, the air inlets being connected to air inlet pipes 24, one end of the air inlet pipes 24 being movably connected to the air outlets, the air outlets 13 being connected to the main pipe 4 through branch pipes 5, the main pipe 4 being installed on the outer surface of the machine body 1, the top of the main pipe 4 being connected to a hot air device 3 capable of heating air, and the hot air device 3 being installed on the top of the machine body 1.
[0036] It should be noted that: the connecting groove 12 is set on the three inner surfaces of the machine body 1. The hot air device 3 draws in outside air and heats it to generate hot air. This hot air is then transmitted through the main pipe 4 and branch pipes 5 to the air outlet 13. By setting the air outlet 13 and movably connecting it to the air inlet pipe 24, the hot air flowing through the air outlet 13 can enter the air inlet through the air inlet pipe 24 and be transmitted through the channel inside the placement plate 18 to the drying hole 19. The hot air from the drying hole 19 can dry the multi-layered wood products placed above the placement plate 18, and... The arrangement of multiple placement boards 18 from top to bottom allows multi-layered wood products to be placed on the placement boards 18 separately.

[0040] It should be noted that by setting up the partition 30, the chamber 9 can be divided. The heated air is sent to one side of the partition 30 for storage, and the air is heated on the other side of the partition 30. The heating and storage are separated. In subsequent operations, when hot air is needed, the stored hot air can be directly sent into the main pipe 4 to improve drying efficiency.
[0041] In the embodiments of this utility model, reference is made to Figure 4 As shown, a protective ring 25 is fitted onto the outer surface of the air inlet pipe 24, and the protective ring 25 is made of rubber.
[0042] It should be noted that by setting a rubber protective ring 25, when the air inlet pipe 24 and the air outlet 13 are connected, the connection between the air inlet pipe 24 and the air outlet 13 can be sealed by the blocking of the protective ring 25, thereby improving the sealing performance of the connection.
[0043] In the embodiments of this utility model, reference is made to Figure 2 As shown, the side of the main pipe 4 is connected to one end of the second branch pipe 8, the second branch pipe 8 is connected to the upper air inlet, the upper air inlet is located at the top of the body 1, the upper air inlet is connected to multiple upper air outlets 16 through a channel, and the upper air outlets 16 are located at the top of the interior of the body 1.
[0044] In the embodiments of this utility model, reference is made to Figure 4 As shown, the top edge of the placement plate 18 is provided with a plurality of ventilation holes 20.
[0045] It should be noted that by setting the upper air outlet 16, hot air can be sent in from the upper part of the machine body 1 to dry the inside of the machine body 1. By setting the ventilation hole 20, the hot air entering from the upper part of the machine body 1 can enter the lower part of the machine body 1 through the ventilation hole 20, so that the hot air can fill the entire machine body 1 and improve the drying efficiency.
[0046] In the embodiments of this utility model, reference is made to Figure 4 As shown, the side of the placement plate 18 is provided with a connecting ring 23, and the connecting ring 23 is U-shaped.
[0047] It should be noted that by setting the U-shaped connecting ring 23, the placement plate 18 can be moved back and forth by holding the connecting ring 23.
[0048] In the embodiments of this utility model, reference is made to Figure 3 As shown, the side of the body 1 is provided with multiple internal air outlets 17, and the internal air outlets 17 are connected to the upper air inlet through channels.
[0049] It should be noted that by setting multiple internal air outlets 17, hot air can be easily sent in from the side of the machine body 1 to dry the inside of the machine body 1, so that the hot air can fill the entire machine body 1 and improve the drying efficiency.
[0050] In the embodiments of this utility model, reference is made to Figure 3 , Figure 4 As shown, the two sides of the placement plate 18 are respectively provided with a first positioning hole 21 and a second positioning hole 22. The first positioning hole 21 and the second positioning hole 22 are slidably connected to the first positioning shaft 14 and the second positioning shaft 15, respectively. One end of the first positioning shaft 14 and the second positioning shaft 15 are respectively connected to the two ends of the horizontal part of the connecting groove 12.
[0051] It should be noted that by setting the first positioning hole 21 and the second positioning hole 22, the first positioning shaft 14 and the second positioning shaft 15 can limit the placement plate 18 to move along the set route when it moves, so as to connect the air inlet pipe 24 and the air outlet 13.
[0052] In the embodiments of this utility model, reference is made to Figure 2 As shown, the outer surface of the main pipe 4 is bonded with a heat insulation cylinder 6, which is made of heat insulation material.
[0053] It should be noted that by setting up an insulation cylinder 6 made of heat-insulating material, the outer surface of the main pipe 4 can be insulated. When the hot air generated by the hot air device 3 enters the main pipe 4, the heat exchange between the main pipe 4 and the outside world is reduced, thereby protecting the temperature of the hot air.
[0054] The working principle of the vertical drying machine for processing multi-layer board wood products provided by this utility model is as follows:
[0055] Hot air is drawn in and heated by the hot air device 3 to generate hot air. This hot air is then driven by the main pipe 4 and branch pipes 5 into the air outlet 13. The air outlet 13 is connected to the air inlet pipe 24, allowing the hot air flowing through it to enter the air inlet through the inlet pipe 24. The hot air is then transmitted through the channels inside the placement plate 18 to the drying hole 19. The hot air from the drying hole 19 dries the multi-layered wood products placed above the placement plate 18. Furthermore, due to the multiple placement plates 18 arranged from top to bottom... The design allows for the separate placement of multi-layered wood products on the placement boards 18. This prevents uneven heating of each layer of wood during drying due to the accumulation of wood products, which would otherwise require longer drying times and increase energy consumption. Furthermore, each placement board 18 is equipped with a drying hole 19, allowing each board to emit hot air independently. This ensures that the multi-layered wood products placed on the placement board 18 are heated evenly, improving the drying effect and preventing cracking caused by uneven heating, which could damage the wood's properties and affect its quality.
[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
