Technical Field
[0001] This utility model relates to the field of impregnated paper technology, and in particular to a vertical drying device for impregnated paper. Background Technology
[0002] Impregnated paper is a special type of paper that has been impregnated with chemical agents such as resins, oils, asphalt, and waxes. The production and processing of impregnated paper consists of six stages: preparation, humidification, pre-impregnation, sizing, drying, and post-treatment. The impregnation process involves immersing the base paper in an impregnation solution, where the paper is saturated as it moves through the solution. The impregnated paper is then coated with the required sizing solution on both sides using an impregnation tank or coating roller. After coating, the impregnated paper generally needs to be dried. Existing drying equipment is typically a horizontal impregnated paper dryer, which has the following shortcomings:
[0003] 1. Existing industrial plants have large floor areas and high ceilings, while horizontal dryers have large machine volumes. They occupy more horizontal space than vertical space in industrial plants, resulting in reduced utilization of vertical space and wasted space.
[0004] 2. Existing dryers typically have several guide rollers arranged vertically and alternately within the drying chamber to guide the movement of the impregnated paper. The impregnated paper moves vertically and alternately along the guide rollers to maximize the drying time within a limited space. However, it should be noted that, on the one hand, if the lateral distance between the guide rollers is too close, the spacing between adjacent impregnated paper sheets is small when the impregnated paper passes through the guide rollers, which to some extent affects the airflow on the surface of the impregnated paper and affects the drying efficiency. On the other hand, if the vertical distance between adjacent guide rollers is too far, the impregnated paper remains wavy. When the impregnated paper moves from the upper guide roller to the lower guide roller, the impregnating adhesive on the impregnated paper slides down the impregnated paper under the action of gravity. Since the impregnated paper is being dried at the same time, it is easy for the impregnating adhesive to leave watermarks on the impregnated paper as it moves.
[0005] 3. Existing dryers usually have an insulation layer installed inside the side wall. After drying, the heat dissipation effect of the dryer is generally poor. If the dryer maintains a high temperature for a long time, it is easy to damage the dryer body.
[0006] Therefore, how to design a vertical drying equipment for impregnated paper that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0011] The dryer box side wall has an impregnation liquid outlet hole that is connected to the first V-shaped liquid guide plate, the second V-shaped liquid guide plate and the third V-shaped liquid guide plate at its lowest end.
[0012] The guide roller assembly includes several first guide rollers fixed directly below the fixed end of the first V-shaped liquid guide plate, several second guide rollers fixed directly below the movable end of the first V-shaped liquid guide plate and cooperating with the first guide rollers, several third guide rollers fixed directly below the fixed end of the second V-shaped liquid guide plate and arranged parallel to the second guide rollers, several fourth guide rollers fixed directly below the movable end of the second V-shaped liquid guide plate and cooperating with the first guide rollers, a fifth guide roller fixed at the impregnated paper inlet position, a sixth guide roller arranged parallel to the fifth guide roller and the first guide roller, and an outlet guide roller fixed at the first impregnated paper outlet.
[0013] Furthermore, both the first and second V-shaped liquid guide plates have mounting grooves extending through their side plates, and the first and second V-shaped liquid guide plates have mounting cavities that communicate with the mounting grooves; each mounting groove has an air guide strip; and each mounting cavity has a drive motor that is fixedly connected to the air guide strip for controlling the opening and closing of the air guide strip.
[0014] Furthermore, a V-shaped baffle plate is slidably provided on the outer side of the movable end of the first V-shaped liquid guide plate and the second V-shaped liquid guide plate, and an X-axis assembly is provided on the outer side of the movable end of the first V-shaped liquid guide plate and the second V-shaped liquid guide plate along their length direction, and the V-shaped baffle plate is installed on the X assembly.

[0043] Furthermore, both the first V-shaped liquid guide plate 51 and the second V-shaped liquid guide plate 52 have mounting grooves 511 extending through their side plates, and both the first V-shaped liquid guide plate 51 and the second V-shaped liquid guide plate 52 have mounting cavities 512 that communicate with the mounting grooves 511; each mounting groove 511 has an air guide strip 513; each mounting cavity 512 has a drive motor 514 that is fixedly connected to the air guide strip 513 for controlling the opening and closing of the air guide strip 513.

[0045] Furthermore, the X-axis assembly 515 is a linear module.
[0046] Furthermore, a liquid discharge plate 14 is provided below the fifth guide roller 65 and the sixth guide roller 66 at the bottom of the dryer box 1, and a liquid guide hole 15 connected to the liquid discharge plate 14 is provided on the side wall of the dryer box 1.
[0047] Furthermore, a second impregnated paper outlet 16 is provided on the side wall of the dryer box 1 at the positions corresponding to the second guide roller 62 and the fourth guide roller 64; a seventh guide roller 17 is fixed on the outer side wall of the dryer box 1 at the position corresponding to the second impregnated paper outlet 16.
[0048] Furthermore, a baffle 18 is slidably provided on the outer wall of the dryer box 1 at a position above the second impregnated paper outlet 16, and a Z-axis assembly 19 is provided on the outer wall of the dryer box 1 at a position above the second impregnated paper outlet 16 along its height direction, and the baffle 18 is installed on the Z-axis assembly 19.
[0049] Furthermore, the Z-axis component 19 is a linear module.
[0050] Furthermore, the drying chamber 1 is provided with a heat insulation layer 10 inside the side wall.
[0051] The working principle is roughly as follows:
[0052] The impregnated paper enters the drying chamber 1 through the impregnated paper inlet 11, passing sequentially through the fifth guide roller 65, the sixth guide roller 66, and then sequentially through the first guide roller 61, the second guide roller 62, the third guide roller 63, the fourth guide roller 64, and so on, causing the impregnated paper to be arranged in a serpentine pattern within the drying chamber 1. Figure 4 As shown;
[0053] During drying, the impregnated paper first passes under the dehumidifier and is dehumidified by the dehumidifier 42 to reduce the moisture on the impregnated paper. At the same time, some of the impregnating liquid drips onto the liquid outlet plate 14 under the influence of gravity and flows out through the liquid outlet hole 15. The hot air blower 2 continuously supplies hot air into the drying chamber 1 through the air outlet duct. The hot air enters from the bottom of the drying chamber 1 and naturally rises due to density factors, further improving energy efficiency compared to ordinary horizontal dryers, and dries the impregnated paper. According to the drying requirements of the impregnated paper, the V-shaped baffle 53 at the movable end of the corresponding first V-shaped guide plate 51 (or second V-shaped guide plate 52) is extended and abuts against the side wall of the drying chamber, creating a relatively sealed drying space between the bottom of the first V-shaped guide plate 51 and the drying chamber 1. Simultaneously, the corresponding baffle 18 moves upward, and the impregnated paper enters from the impregnated paper inlet 11 and exits from the corresponding second impregnated paper outlet 16 below the first V-shaped guide plate 51 (or second V-shaped guide plate 52). Figure 5 As shown, the drying time of the impregnated paper in the drying chamber can be flexibly reduced according to the drying needs of the impregnated paper.
[0054] After drying, the air guide strip 513 is rotated by the drive motor 514, which opens the air guide strip 513, improves the efficiency of air circulation in the drying chamber, and speeds up the heat dissipation efficiency in the drying chamber after use.
[0055] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
