Description

Technical Field

[0001] This utility model relates to the technical field of flat plate drying devices, and in particular to a flat plate drying device. Background Technology

[0002] In the production and processing of sheet metal products, a cleaning process is usually required to remove surface stains and impurities to ensure the surface quality and subsequent processing accuracy. After cleaning, the residual moisture on the sheet surface must be dried using a drying device.

[0003] To improve production efficiency, continuous conveyor structures are commonly used. This involves a conveyor mechanism that continuously transports the cleaned flat plates forward, allowing them to dry during the process. Currently, most drying equipment uses perforated conveyor belts as the conveying medium. These belts circulate through large rotating drums positioned at the front and rear, thus synchronously transporting the flat plates placed on the conveyor belt forward.

[0004] However, during the conveying and drying process, the flat plate and the conveyor belt surface remain relatively stationary. The area where the bottom of the flat plate contacts the conveyor belt is blocked, making it difficult for the water on its surface to be effectively drained through the holes in the conveyor belt. This results in water residue forming in this area, leading to poor drying effect and making it difficult to meet the cleaning quality requirements of the flat plate.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a flat plate drying device, which aims to solve the technical problem of poor drying effect in the prior art.

Both the upper and lower water-blocking strips have multiple semi-circular notches. Each roller has a water-blocking ring at both ends. The notch is located outside the water-blocking ring, and the inner diameter of the notch is smaller than the outer diameter of the water-blocking ring.

[0016] Furthermore, a water receiving tray is provided at the bottom of the lower oven, the water receiving tray is obliquely downward along the flat plate conveying direction, and a drain pipe extending to the outside of the lower oven is provided at the inclined end of the water receiving tray; a plurality of first drain holes are provided on the lower baffle strip, the first drain holes being located above the water receiving tray.

[0017] Furthermore, the conveying plane formed by the plurality of rollers is arranged obliquely downward along the flat conveying direction.

[0018] Furthermore, the driving mechanism includes a drive motor, which is connected to one of its rollers via a first chain drive assembly, and two adjacent rollers are connected sequentially via a second chain drive assembly.

[0019] Furthermore, the fan disc includes a fan shroud, a first air guide strip, and a second air guide strip.

Each second air guide strip includes two second guide plates and a second connecting plate connecting the two second guide plates. The second guide plates of two adjacent second air guide strips are located inside the two first guide plates on the corresponding first air guide strip.

[0020] Furthermore, the two first guide plates of the first air guide strip located in the upper oven are both inclined along the flat conveying direction.

[0021] Furthermore, the second air outlet of the lower oven is located below the two adjacent rollers.

[0022] Furthermore, the side wall of the hood of the lower oven is provided with a number of second water leakage holes, and the multiple second water leakage holes are arranged one-to-one with the multiple second air guide strips.

[0023] Furthermore, both ends of the upper oven are provided with a first baffle plate with adjustable height; both ends of the lower oven are provided with a second baffle plate.

[0024] Beneficial effects:

Detailed Implementation

[0036] This utility model provides a flat plate drying device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0038] Please see Figures 1 to 9As shown, this utility model provides a flat drying device, including: a frame 1, a drive mechanism 3, an upper drying oven 4, a lower drying oven 5, a ventilation pipe 7, and a return air pipe 9. The frame 1 has several rollers 2 arranged at intervals along the flat conveying direction. The drive mechanism 3 is mounted on the frame 1 and is used to drive all the rollers 2 to rotate synchronously. The upper drying oven 4 is located above the rollers 2, and its side wall has a first air inlet 41. The lower drying oven 5 is located below the rollers 2, and its side wall has a first air outlet 51. The upper drying oven 4 and the lower drying oven 5 are separate... A separate fan plate 6 is provided, which has a second air inlet 61. The fan plate 6 has several strip-shaped second air outlets 62 on the wall near the roller 2. One end of the ventilation pipe 7 is connected to the first air inlet 41 of the upper oven 4 and the second air inlets 61 of the two fan plates 6 respectively. The other end of the ventilation pipe 7 is connected to a hot air circulation device 8 for introducing hot air into the first air inlet 41 and the second air inlet 61. One end of the return air pipe 9 is connected to the first air outlet 51 of the lower oven 5, and the other end is connected to the hot air circulation device 8.

[0039] During the drying process, the drive mechanism 3 drives all the rollers 2 on the frame 1 to rotate synchronously. The cleaned flat plate is placed on the rollers 2 and continuously conveyed forward along the conveying direction as the rollers 2 rotate. At this time, the external hot air circulation device 8 sends hot air into the drying device through the ventilation pipe 7. Part of the hot air enters the interior of the upper drying oven 4 through the first air inlet 41 on the side wall of the upper drying oven 4, and the other part enters the fan coil unit 6 through the two second air inlets 61 respectively. The upper drying oven 4 and the lower drying oven 5 cooperate to form a relatively sealed drying space to reduce heat loss. The fan coil unit 6 in the upper drying oven 4 and the lower drying oven 5 blows hot air directly and evenly onto the upper and lower surfaces of the flat plate during the conveying process through several strip-shaped second air outlets 62 on the side near the rollers 2, realizing targeted drying of the flat plate; at the same time, the hot air entering the interior of the upper drying oven 4 fills the oven space, forming a heat preservation environment and helping to maintain the temperature stability of the drying area. After heat exchange, the hot air gathers in the lower oven 5 and finally enters the return air pipe 9 through the first air outlet 51 on the side wall of the lower oven 5, and flows back to the hot air circulation device 8 for heating and recycling, forming a complete hot air circulation system.

[0040] Compared to existing technologies, the use of multiple rollers 2 to convey the flat plate, with each roller 2 making line contact with the flat plate, greatly reduces the contact area between the flat plate and the conveying components, thus reducing the possibility of water accumulation at the contact points. Furthermore, the strip-shaped second air outlet 62 of the two fan discs 6 allows hot air to directly act on the surface of the flat plate. Combined with the heat preservation effect of the enclosed space, this effectively improves drying efficiency and uniformity, resulting in a good drying effect that meets the drying requirements of the flat plate.

[0041] Preferably, the walls of both the upper oven 4 and the lower oven 5 are provided with insulation layers to further enhance the heat insulation performance of the ovens.

[0042] Preferably, the upper oven 4 is provided with at least one closed door 44, which is adapted to the side wall of the upper oven 4 and has a sealing structure, which may be a sealing ring wrapped around the closed door 44. By providing the closed door 44, it is convenient for operators to operate inside the upper oven 4, such as to inspect, clean or replace relevant parts.

[0043] The hot air circulation device 8 mentioned above is existing technology. It typically includes heating components (such as electric heating elements), a circulating fan, and a filter component, and has the functions of generating, conveying, and purifying hot air. Its structure and working principle have been widely used in the field of industrial drying equipment, and will not be described in detail here. Using this existing hot air circulation device 8, its basic function is to introduce the generated hot air into the upper drying oven 4 and two fan coil units 6 through the ventilation duct 7, providing a stable heat source for the drying process. Simultaneously, the hot air that has undergone heat exchange in the lower drying oven 5 is returned to this device via the return air duct 9, where it is reheated and then conveyed back to the ventilation duct 7, forming a closed-loop circulation.

[0044] In a preferred embodiment, see [reference] Figure 6-9 It also includes two upper water-blocking strips 42 symmetrically arranged at the bottom of the upper oven 4, and two lower water-blocking strips 52 symmetrically arranged at the top of the lower oven 5. Both the upper and lower water-blocking strips 42 and 52 have multiple semi-circular notches 421. Each roller 2 has a water-blocking ring 21 at both ends. The water-blocking ring 21 rotates with the roller 2. The notch 421 is located inside the water-blocking ring 21, and the inner diameter of the notch 421 is smaller than the outer diameter of the water-blocking ring 21. This avoids interference between the water-blocking strip and the roller 2, and also seals the water-blocking structure with the water-blocking ring 21. During the conveying process of the flat plate, the residual moisture on its surface evaporates due to heat or flows to the edge due to gravity. Some of the unevaporated moisture may also be thrown towards the inner wall of the oven as the roller 2 rotates, or overflow outward along the end of the roller 2. The upper baffle strip 42 and the lower baffle strip 52 can intercept water flowing towards the inner wall of the oven, preventing water from splashing directly out of the oven through the gap between the oven and the drum 2; the baffle rings 21 at both ends of the drum 2 can block water that spreads along the axis of the drum 2, preventing it from spreading to the end of the drum 2; and the lower baffle strip 52 collects the water blocked by the baffle rings 21, preventing the water from splashing out of the oven from the end of the drum 2.

[0045] Further, see Figure 4The lower drying oven 5 has a water collection tray 10 at its bottom. The water collection tray 10 collects residual moisture that cannot evaporate during the flatbed drying process: moisture intercepted by the upper and lower baffles 42 and 52, moisture dripping from the flatbed surface, and other liquid water that has not been evaporated by the hot air. The water collection tray 10 is angled downwards along the flatbed conveying direction, and a drain pipe 101 extending from the angled end of the water collection tray 10 to the outside of the lower drying oven 5 is provided. Specifically, the water collection tray 10 is angled downwards at 1°-3° along the flatbed conveying direction. This angled arrangement creates natural drainage, causing the collected moisture to converge towards a lower position along the surface of the water collection tray 10 and finally be discharged directly through the drain pipe 101.

[0046] like Figure 9 As shown, the lower water baffle 52 is provided with a plurality of spaced first water leakage holes 521. The first water leakage holes 521 are located above the water receiving tray 10. The water collected by the lower water baffle 52 can fall directly into the water receiving tray 10 through the first water leakage holes 521, thus avoiding accumulation in the lower water baffle 52.

[0047] In a preferred embodiment, the conveying plane formed by the plurality of rollers 2 is arranged obliquely downward along the conveying direction of the flat plate. Specifically, the inclination angle of the conveying plane is 1°-3°. In practical applications, the synchronous rotation speed of the rollers 2 is matched with the inclination angle to ensure that the flat plate maintains a stable posture during conveying and will not slide or deviate due to inclination. When the flat plate is placed on the inclined conveying plane, the water remaining on its surface will flow naturally downstream along the inclination direction under the action of gravity. Combined with the directional hot air blown out by the fan 6, on the one hand, the hot air directly heats the water and accelerates evaporation; on the other hand, the airflow has a "boosting" effect on the flowing water, further accelerating the flow speed of the water along the surface of the flat plate, causing the water to quickly leave the surface of the flat plate, effectively avoiding the possibility of water marks or stains forming due to prolonged water retention on the surface of the flat plate.

[0048] In a preferred embodiment, see [reference] Figure 1 , 3 The driving mechanism 3 includes a drive motor 31, which is connected to one of its rollers 2 via a first chain drive assembly 32. Two adjacent rollers 2 are connected in sequence via a second chain drive assembly 33.

[0049] Specifically, both the first chain drive assembly 32 and the second chain drive assembly 33 are sprocket and chain drive assemblies, which feature high transmission efficiency and ease of installation, maintenance, and replacement. Through this configuration, the power output from the drive motor 31 is transmitted to one roller 2 via the first chain drive assembly 32, and then sequentially transmitted to adjacent rollers 2 via the second chain drive assembly 33, forming a continuous power transmission path. This ensures that all rollers 2 maintain a consistent speed and direction of rotation, thereby achieving synchronous rotation of all rollers 2.

[0050] In the alternative solutions, such as Figure 3 As shown, the drive motor 31 can be connected to two rollers 22 through the first chain drive assembly 32, and the two rollers 2 are respectively connected to adjacent rollers 2 through the second chain drive assembly 33. The remaining two adjacent rollers 2 are connected in sequence through the second chain drive assembly 33, which can also realize the synchronous rotation of all rollers 2.

[0051] It should be noted that the second chain drive assembly 33 includes sprockets. Each roller 2 has two sprockets at one end, and each sprocket forms a chain drive with the sprocket on the adjacent roller 2 via a chain. Since the second chain drive assembly 33 is located outside the upper baffle 42 and the lower baffle 52, it effectively prevents water from splashing onto the connection between the roller 2 and the frame 1 and onto the second chain drive assembly 33, avoiding moisture from causing corrosion to the transmission components or affecting the transmission stability. Furthermore, since the second chain drive assembly 33 is located outside the oven, it is protected from the influence of hot air, and it is also convenient for operators to perform daily inspections, lubrication, and maintenance, thus improving the ease of equipment maintenance.

[0052] In a preferred embodiment, see [reference] Figure 4 , 5 The fan plate 6 includes a fan cover 63, a first air guide strip 64, and a second air guide strip 65. A plurality of first air guide strips 64 are spaced apart on the side of the fan cover 63 near the roller 2. Each first air guide strip 64 includes two first guide plates 641 and a first connecting plate 642 connecting the two first guide plates 641. The first guide plates 641 of two adjacent first air guide strips 64 form the second air outlet 62. A plurality of second air guide strips 65 are spaced apart between the inner wall of the fan cover 63 and the second air outlet 62. Each second air guide strip 65 includes two second guide plates 651 and a second connecting plate 652 connecting the two second guide plates 651. The second guide plates 651 of two adjacent second air guide strips 65 are located on the inner side of the two first guide plates 641 on the corresponding first air guide strip 64. During the drying process, hot air enters the air hood 63 through the second air inlet 61 of the air disc 6. It is first guided and divided by the second air guides 65: the hot air is dispersed outwards by the second connecting plate 652 of the second air guide 651, thus evenly distributing it to various areas within the air hood 63. Subsequently, the divided hot air flows through the gap between the second air guides 651 of adjacent second air guides 65 and into the first air guide 64 located between the two second air guides 65. Finally, the hot air is directionally blown onto the flat plate surface through the gap between the first air guides 641 of adjacent first air guides 64 (i.e., the second air outlet 62). Through this arrangement, the hot air can flow orderly along a preset path, concentrating the airflow on the flat plate surface, effectively reducing hot air diffusion loss, and further accelerating the drying efficiency.

[0053] Further, see Figure 5The two first guide plates 641 located on the first air guide strip 64 of the upper oven 4 are inclined along the flat plate conveying direction, so that the hot air blown out of the second air outlet 62 formed by the two has a directional component force along the flat plate conveying direction. Combined with the inclined setting of the flat plate conveying plane, when the hot air blows onto the upper surface of the flat plate through the second air outlet 62, the airflow thrust along the conveying direction and the guiding effect of gravity on the water accumulation are superimposed, forming a stronger "boosting" effect on the water flowing on the flat plate surface, further increasing the movement speed of the water on the flat plate surface, so as to accelerate the process of the water detaching from the flat plate surface, thereby improving the overall drying efficiency and the surface quality of the flat plate.

[0054] Further, see Figure 5 The second air outlet 62 of the lower oven 5 is located below the two adjacent rollers 2. Hot air can blow vertically upwards onto the unobstructed area of ​​the lower surface of the flat plate. At the same time, some airflow can diffuse upwards along the side wall of the roller 2 to avoid the formation of a drying blind zone due to the obstruction of the roller 2. Meanwhile, the upward-blown hot air creates an upward airflow thrust on the water remaining on the lower surface of the flat plate, accelerating the flow of the water towards the edge of the flat plate. Some of the water will drip directly onto the lower fan plate 6, while the other part of the water will flow along the axial direction of the roller 2 to its end and converge to the lower baffle strip 52 under the action of the baffle ring 21. Finally, it will flow into the water receiving tray 10 through the first drain hole 521 of the lower baffle strip and be discharged.

[0055] Furthermore, see Figure 5 The side wall of the hood 63 of the lower oven 5 is provided with a plurality of second drainage holes 631, and the plurality of second drainage holes 631 are arranged one-to-one with the plurality of second air guides 65 to ensure that the water accumulated in each second air guide 65 can be discharged accordingly. In the lower oven 5, the dripping water falls into the second air guide 65 through the second air outlet 62 and collects on the surface of the second connecting plate 652 of the second air guide 65; the collected water is quickly discharged out of the hood 63 through the second drainage holes 631 and drips into the water receiving tray 10 below, avoiding the problem of water accumulation inside the hood 63 or on the second air guide 65.

[0056] In a preferred embodiment, see [reference] Figure 8The upper drying oven 4 has height-adjustable first baffle plates 43 at both ends. Specifically, the first baffle plates 43 have at least two vertically extending slots 431. Screws are passed through the slots 431 to install the first baffle plates 43 at the bottom of the upper drying oven 4. During adjustment, after loosening the screws, they can slide along the vertical direction of the slots 431, thus flexibly adjusting the installation height of the first baffle plates 43. In actual operation, the operator can adjust the height of the first baffle plates 43 according to the thickness of the flat plate to be dried, so that the distance between its bottom and the conveying plane of the roller 2 is slightly greater than the thickness of the flat plate. This avoids frictional interference between the flat plate and the first baffle plates 43 during conveying and minimizes the gap between them.

[0057] See Figure 9 The lower oven 5 is equipped with second baffles 53 at both ends. These baffles 53 are installed between two adjacent rollers 2, with their tops positioned close to the conveying plane formed by the rollers 2, thereby sealing the gap between the ends of the lower oven 5 and the conveying plane. This design improves the sealing between the oven and the conveying plane of the rollers 2: on the one hand, it effectively reduces the loss of high-temperature hot air inside the oven, lowering energy consumption; on the other hand, it prevents low-temperature air from intruding into the oven, thus ensuring the stability of the oven's internal temperature.
