Abstract
Description
Technical Field
[0001] This utility model relates to the field of building material processing equipment technology, and in particular to a humidification device for building panels. Background Technology
[0002] In the construction industry, many types of boards (such as gypsum board, cement fiberboard, and wood composite board) may have excessively low moisture content during manufacturing, storage, and transportation. Dry boards are prone to problems such as edge chipping, surface cracking, dimensional instability, and poor adhesion to adhesives when subjected to subsequent processes such as cutting, installation, surface coating, and bonding. Therefore, properly humidifying the boards before processing to achieve an ideal moisture level is a crucial step in ensuring product quality and construction results.
[0003] There are two main existing methods for humidifying boards: one is to manually spray water using tools such as sprayers. This method is inefficient, the water volume is difficult to control, and the humidity uniformity is extremely poor, which can easily cause localized over-wetting of the board while other parts remain dry. The other method is to send the board through a device equipped with spray heads via a conveyor belt. Although this device achieves automation, the water droplets it sprays are relatively large, which can easily form water streams or puddles on the surface of the board, resulting in uneven water penetration. In severe cases, it can soak and damage the board, causing material waste. At the same time, this process consumes a lot of water and usually can only humidify one side of the board, which may cause the board to warp and deform due to moisture absorption on one side.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] like Figures 1 to 2 As shown, this utility model provides a humidification device for building panels, including: a box body 1, a panel feeding unit, an atomizing unit 2, and a recovery unit 3; the box body 1 has a first end 11 and a second end 12 arranged along the conveying direction D of the panels, the first end 11 having an inlet and the second end 12 having an outlet 121; the panel feeding unit is disposed inside the box body 1 and is used to convey the panels entering from the inlet along the conveying direction D; the atomizing unit 2 is disposed on the box body 1 and has at least one mist outlet, which sprays water mist toward the surface of the panels when the panels enter the box body 1; the recovery unit 3 is connected to the interior of the box body 1 and is used to collect the condensate formed by the water mist inside the box body 1.
[0026] In practice, firstly, the feeding unit transports the boards within the enclosed chamber 1, achieving continuous automation of the humidification process. Compared to manual operation, this significantly improves production efficiency and processing consistency. Secondly, the core atomization unit 2 uses a "water mist" spray instead of the traditional "water droplets" for humidification. This fine medium can more evenly and gently cover the surface of the boards, avoiding the risk of damage caused by excessive water volume and fundamentally improving humidification quality. Finally, the recycling unit 3 collects excess condensed water and makes reuse possible, solving the problem of serious water waste in traditional methods.
[0027] In this embodiment, the plate feeding unit can be a prior art device, such as a conveyor belt.
[0028] According to one embodiment of the present invention, there are two mist outlets, including a first mist outlet and a second mist outlet; the first mist outlet is used to spray water mist toward one side of the board when the board enters the box 1; the second mist outlet is used to spray water mist toward the other side of the board when the board enters the box 1.
[0029] In practical implementation, traditional single-sided humidification means that only one side of the board absorbs moisture, leading to uneven humidity stress within the board. This can cause the board to warp or deform due to swelling from one side. By setting up two mist outlets, one at the top and one at the bottom, the device can humidify both sides of the board simultaneously. This ensures that both main surfaces of the board absorb moisture at similar rates and magnitudes, making the humidity distribution within the board more symmetrical and balanced. This effectively counteracts the internal stress caused by moisture absorption, fundamentally solving the technical problem of board deformation.
[0030] According to one embodiment of the present invention, the atomizing unit 2 includes a water tank 21, an ultrasonic generator, a first mist outlet pipe 22, and a second mist outlet pipe 23; the housing 1 has a first through-hole at the upper end of the housing 1 and a second through-hole at the lower end of the housing 1; the water tank 21 has a first mounting hole and a second mounting hole; the ultrasonic generator is disposed inside the water tank 21; one end of the first mist outlet pipe 22 is connected to the first mounting hole, and the other end of the first mist outlet pipe 22 is connected to the first through-hole, and the port of the other end of the first mist outlet pipe 22 is the first mist outlet; one end of the second mist outlet pipe 23 is connected to the second mounting hole, and the other end of the second mist outlet pipe 23 is connected to the second through-hole, and the port of the other end of the second mist outlet pipe 23 is the second mist outlet.
[0031] In practical implementation, the ultrasonic generator produces "cold" water mist with smaller particle diameters (micrometer level) and more uniform distribution. This water mist has extremely strong penetrability and does not carry excessive heat, enabling deep, uniform, and gentle humidification of the board material. Simultaneously, the structure connecting the first and second mist outlet pipes 23 to the corresponding through-holes on the upper and lower sides of the housing 1 provides a reliable and stable physical channel for simultaneous humidification on both sides, ensuring that the high-quality water mist generated by the ultrasonic waves can be accurately and efficiently delivered to the upper and lower surfaces of the board material. This eliminates the need for two water tanks 21 and two ultrasonic generators.
[0032] According to one embodiment of the present invention, the bottom wall of the box 1 is inclined downward in the opposite direction of the conveying direction D.
[0033] In practice, during the humidification process, excess water mist condenses into droplets that automatically flow downwards along the pre-designed slope due to gravity. This prevents condensate from randomly accumulating at the bottom of the tank, thus eliminating the risk of localized soaking of the lower surface of the panels. More importantly, it requires no additional pumps, scrapers, or other power units; the structure itself completes the water collection preparation, greatly simplifying the structure of the recycling system and reducing energy consumption and failure rate.
[0034] According to one embodiment of the present invention, the bottom wall of the box 1 and the inlet of the inlet plate have a drain hole for draining condensate; the recycling unit 3 is located below the box 1 and communicates with the drain hole.
[0035] In practice, by placing the drain hole at a necessary water flow convergence point, it is ensured that all condensate can be completely and without residue discharged from the tank 1. Simultaneously, the recovery unit 3 is placed below the tank 1, allowing condensate to flow directly and smoothly into the recovery unit 3 under gravity through the drain hole. Combined with the sloping bottom wall design, this forms a complete, gravity-driven passive condensate collection and transfer path, making the entire process highly efficient, reliable, and energy-efficient.
[0036] According to one embodiment of the present invention, the recycling unit 3 is located above the water tank 21 and has a water outlet; the upper end of the water tank 21 has a water inlet hole, which is connected to the water outlet hole.
[0037] In practice, the condensate collected from the recycling unit 3, being higher than the water tank 21, can automatically flow back to the water tank 21 by gravity through the outlet and inlet holes without any power, thus replenishing the water source. This design fully embodies the energy-saving concept, and the process of "lifting" the recycled water back to the source water tank 21 is also achieved in a powerless manner, minimizing the operating cost and system complexity of the device.
[0038] According to one embodiment of the present invention, it further includes a return pipe 4 and a one-way valve; one end of the return pipe 4 is connected to the water outlet, and the other end of the return pipe 4 is connected to the water inlet; the one-way valve is provided on the return pipe 4 to conduct water from the water outlet to the water inlet.
[0039] According to one embodiment of the present invention, it further includes a controller and a humidity sensor; the humidity sensor is disposed inside the housing 1; the controller is electrically connected to the humidity sensor and the ultrasonic generator, and is used to reduce the power of the ultrasonic generator when the humidity sensor detects a humidity value higher than a preset value.
[0040] In practice, a humidity sensor monitors the humidity inside the chamber in real time, and the controller compares the actual humidity with a preset value. When the humidity is too high, the controller automatically reduces the power of the ultrasonic generator, thereby reducing the amount of mist produced.
[0041] According to one embodiment of the present invention, the controller is used to increase the power of the ultrasonic generator when the humidity sensor detects that the humidity value is lower than a preset value.
[0042] In practice, regardless of whether the initial humidity is high or low, the system can automatically increase or decrease the mist output to actively and accurately maintain the humidity inside the chamber near the user-set optimal process value. This elevates the automation level and control precision of the device to a new level, enabling it to fully adapt to various complex production needs and ensuring that the final product has a highly consistent ideal moisture content.
[0043] According to one embodiment of the present invention, it further includes a first flexible curtain and a second flexible curtain for reducing the escape of water mist inside the box 1; the first flexible curtain is disposed on the upper edge of the inlet; the second flexible curtain is disposed on the upper edge of the outlet 121.
[0044] In practice, the above-mentioned structural design can effectively reduce the escape of water mist inside the chamber 1, firmly locking the humidified environment inside the chamber 1 and saving energy (reducing the loss of water mist and heat).
[0045] In this embodiment, the first flexible curtain and the second flexible curtain can be existing technologies.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
