Abstract
Description
Technical Field
[0001] This utility model relates to the field of dryer technology, specifically a device for uniformly drying filter paperboard. Background Technology
[0002] In the production of filter paperboard, the drying process plays a crucial role in product quality. In the current production process, after pulping and forming, the filter paperboard is in a high moisture content state. To meet the requirements of subsequent use, drying equipment must be used to reduce its moisture content, thereby ensuring that it meets the predetermined standards for dryness, filtration effect, and strength.
[0003] Traditional drying methods primarily rely on placing filter paperboards inside an oven. While this method allows the oven to deliver airflow along a pre-set path, achieving some degree of airflow dispersion, the fixed position of the filter paperboard prevents the drying airflow from reaching all parts of the paperboard evenly. This leads to localized over-drying while other areas remain under-dryed, severely impacting the overall quality consistency of the filter paperboard. Furthermore, changing the filter paperboard during drying requires opening the oven door and replacing a large quantity at once, a time-consuming process that significantly reduces the continuous operating capacity of the drying equipment, resulting in low production efficiency.
[0004] Therefore, this utility model provides a device for uniformly drying filter paperboard. Utility Model Content

A drying chamber is mounted on the drying hot air blower, and a rotating carrier ring is rotatably connected to the inner wall of the drying chamber. A discharge hopper is located between the drying hot air blower and the drying chamber. The two delivery pipes are respectively installed on corresponding sides of the drying chamber. A feeding channel is fixedly connected to one side of the drying chamber, and a baffle is hinged to the inner wall of the feeding channel. Several perforated dividing mesh frames are installed on the side wall of the rotating carrier ring, and these perforated dividing mesh frames rotate with the rotating carrier ring on the inner wall of the drying chamber. Several rollers are installed on both sides of each perforated dividing mesh frame. The discharge hopper communicates with the internal space of the drying chamber, and a hopper door is installed on one side of the discharge hopper.
[0007] Preferably, an arc-shaped baffle is fixedly connected to the inner wall of the drying chamber, and the rotating carrier ring is slidably connected to the outside of the arc-shaped baffle, with the arc-shaped baffle corresponding to the opening position of the flow pipe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 A filter paperboard uniform drying device includes a drying hot air blower 1 and two flow pipes 11. A drying chamber 2 is provided on the drying hot air blower 1. A rotating carrier ring net 3 is rotatably connected to the inner wall of the drying chamber 2. A discharge bin 4 is provided between the drying hot air blower 1 and the drying chamber 2.
[0022] Two feed pipes 11 are respectively installed on one side of the drying chamber 2. A feed channel 21 is fixedly connected to one side of the drying chamber 2, and a baffle 211 is hinged to the inner wall of the feed channel 21.
[0023] It should be noted that a torsion spring is installed between the feed channel 21 and the baffle 211 described in this embodiment, so that the baffle 211 can be stably rotated to the blocking angle with the feed channel 21 without being affected by external force.
[0024] Several hollowed-out partition frames 31 are installed on the side wall of the rotating carrier ring 3. The hollowed-out partition frames 31 rotate with the rotating carrier ring 3 on the inner wall of the drying chamber 2. Several rollers 32 are installed on both sides of the hollowed-out partition frames 31.
[0025] It should be noted that the filter paperboard described in this embodiment is engaged with the two adjacent perforated partition frames 31.
[0026] The discharge hopper 4 is connected to the interior space of the drying chamber 2, and a hopper door 41 is installed on one side of the discharge hopper 4.
[0027] It should be noted that the feeding channel 21 and the discharge bin 4 described in this embodiment correspond to the two opening positions on the side wall of the drying chamber 2, respectively.
[0028] Specifically, the drying hot air blower 1 delivers airflow for drying to the interior of the drying chamber 2 through two delivery pipes 11. The drying chamber 2 provides space for drying the filter paperboard. The drying chamber 2 stores and drives several filter paperboards one by one through a rotating carrier ring 3 and several hollowed-out partition frames 31. The baffle 211 is opened by a robotic arm, allowing the filter paperboard to be placed into the feeding channel 21. The paperboard slides smoothly between the two hollowed-out partition frames 31. Several arc-shaped baffles 22 on the hollowed-out partition frames 31 reduce the sliding resistance, making it easy for the filter paperboard to be completely inserted between the two hollowed-out partition frames 31. Both the rotating carrier ring 3 and the hollowed-out partition frames 31 are mesh-like designs, which facilitates the airflow to pass through the rotating carrier ring 3 and the hollowed-out partition frames 31 and act on the filter paperboard. The rotating carrier ring 3 drives... The perforated dividing frame 31 rotates, and the filter paperboard continuously adjusts its position inside the drying chamber 2. The airflow delivered by the two flow pipes 11 rotates inside the drying chamber 2, improving the dispersion effect of the hot airflow. This allows the filter paperboard to be dried more evenly, acting on all parts of the paperboard and improving the drying effect. The perforated dividing frame 31 pushes the filter paperboard to rotate. When the filter paperboard rotates to the corresponding diameter of the discharge bin 4, it is no longer blocked by the drying chamber 2, allowing the filter paperboard to slide smoothly into the discharge bin 4 for temporary storage. The bin door 41 can be opened at regular intervals to remove the filter paperboard, completing one cycle. This allows the filter paperboard to be dried while in motion. One filter paperboard is discharged, and then another is immediately filled in. There is no need to stop the machine to change materials, improving the continuity and efficiency of the drying work.
[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, an arc-shaped baffle plate 22 is fixedly connected to the inner wall of the drying chamber 2, and a rotating ring net 3 is slidably connected to the outside of the arc-shaped baffle plate 22. The arc-shaped baffle plate 22 corresponds to the opening position of the flow pipe 11.
[0030] It should be noted that the arc-shaped baffle 22 described in this embodiment guides the airflow delivered by the two delivery pipes 11.
[0031] Specifically, the two air delivery pipes 11 are designed at an angle. The airflow blown into the drying chamber 2 by the air delivery pipes 11 first contacts and collides with the inner side of the arc-shaped baffle 22. The arc-shaped baffle 22 uses its arc-shaped surface to redirect the airflow, so that the airflow can move away from the feed channel 21, reduce heat loss, and help the airflow to form a rotating flow trend inside the drying chamber 2.
[0032] In one embodiment of this utility model, such as Figures 1-4 As shown, a triangular drive frame 33 is installed inside the rotating ring net 3. The triangular drive frame 33 is rotatably connected to the inner wall of one side of the drying chamber 2. The arc-shaped baffle plate 22 does not contact the triangular drive frame 33.
[0033] It should be noted that, in this embodiment, a motor driving the triangular drive frame 33 is installed on one side of the drying chamber 2.
[0034] Specifically, the triangular drive frame 33 supports and drives the rotating carrier ring 3. Driven by the motor, the triangular drive frame 33 completes the rotation adjustment of the rotating carrier ring 3, so that the rotating carrier ring 3 can drive several hollowed-out separator frames 31 and filter paper to rotate and adjust, thereby completing the cyclic drying of the paperboard.
[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, a first drain pipe 42 is installed between the discharge hopper 4 and the drying hot air blower 1. A first shielding net 421 is installed at one end of the first drain pipe 42, and filter nets 422 are provided on both sides of the first drain pipe 42.
[0036] It should be noted that the drying hot air blower 1 described in this embodiment is connected to the internal space of the discharge bin 4 through the first diversion pipe 42, and draws in external air through the filter screen 422.
[0037] Specifically, the drying hot air blower 1 has a built-in air pump, heating mechanism and filtration mechanism. The drying hot air blower 1 draws air from the inside of the discharge bin 4 through the first diversion pipe 42, and the first shielding net 421 shields the filter paper in the discharge bin 4. Since the discharge bin 4 is connected to the internal space of the drying chamber 2, the excess hot air in the drying chamber 2 can be guided back into the drying hot air blower 1 through the discharge bin 4 and the first diversion pipe 42. The drying hot air blower 1 then filters the moisture and heats it again before sending it back into the drying chamber 2 to participate in the drying work, thereby improving the heat reuse rate and reducing energy consumption.
[0038] In one embodiment of this utility model, such as Figures 1-4 As shown, a second drain pipe 43 is installed between the discharge bin 4 and the feed channel 21, and a second shielding net 431 is installed at the top of the second drain pipe 43.
[0039] It should be noted that the discharge bin 4 described in this embodiment is connected to the internal space of the feed channel 21 through the second drain pipe 43.
[0040] Specifically, the discharge bin 4 extracts air from the feed channel 21 through the second drain pipe 43 to reduce the heat at the feed channel 21 and facilitate material discharge. In addition, the second shielding net 431 shields the bottom of the filter paperboard to prevent the paperboard from falling into the discharge bin 4.
[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0042] Working principle: The mechanical arm pushes the baffle 211 to open, allowing the filter paperboard to be placed into the feeding channel 21. The paperboard slides between two adjacent perforated partition frames 31. The drying hot air blower 1 delivers drying airflow into the drying chamber 2 through two delivery pipes 11. The rotating carrier ring 3 drives the perforated partition frames 31 to rotate, causing the filter paperboard to continuously change position. The airflow passes through the mesh-like rotating carrier ring 3 and the perforated partition frames 31 to dry the paperboard. At the same time, the arc-shaped baffle 22 guides the airflow, allowing it to rotate within the drying chamber 2, enhancing the dispersion of hot airflow and achieving uniform drying. The drying hot air blower 1 has a built-in air pump, heating mechanism, and filtration mechanism. Excess hot air in the drying chamber 2 is drawn back to the drying hot air blower 1 through the discharge bin 4 and the first guide pipe 42, where it is re-filtered, reheated, and then sent back into the drying chamber 2, improving heat utilization. When the perforated partition frame 31 pushes the filter paperboard to rotate to the corresponding diameter of the discharge bin 4, the paperboard slides into the discharge bin 4 for temporary storage. The bin door 41 can be opened at regular intervals to remove the paperboard. This device can change materials without stopping the machine, thus improving the continuity and efficiency of the drying process.
