Description

Technical Field

[0001] The utility model relates to the field of waste recycling, and more specifically to a drying device capable of reusing waste heat of waste gas. Background Art

[0002] Flexible circuit boards are highly reliable and extremely flexible printed circuit boards made of polyimide or polyester film as the substrate. They have the characteristics of high wiring density, light weight, thin thickness, and good bendability. Waste gas will be generated during the production process of flexible circuit boards. If the waste gas needs to be reused, a waste gas recycling device is required.

[0003] China Patent Authorization Announcement No.: CN219482082U, provides a waste gas recovery and utilization device. This patent is equipped with a filtering and purification mechanism. First, the waste gas is filtered in multiple stages using the screens arranged at equal distances inside the filter chamber, and then the waste gas is adsorbed and purified by the activated carbon adsorption block. Finally, when the waste gas enters the purification box, the waste gas is flushed and purified by the flushing plate and the water pump, thereby ensuring the purification effect and avoiding secondary pollution.

[0004] In the existing technology, although the exhaust gas can be purified, after the activated carbon board has been used for a long time, the back of the activated carbon board still has relatively surplus adsorption space compared to the front. Since the activated carbon board cannot be turned over, the surplus adsorption space on the back of the activated carbon board cannot be fully utilized, thereby reducing the utilization efficiency of the activated carbon board, increasing material waste, causing inconvenience, and having limitations in use.

[0033] Embodiment 1:

[0034] See also Figure 1-5A drying device for recycling waste heat of exhaust gas comprises a base 1, a box body 11 is fixedly connected to the top of the base 1, and a flip mechanism 2 is arranged inside the box body 11; the flip mechanism 2 is used to improve the utilization rate of materials, and the flip mechanism 2 comprises a fixed frame 21, a rotating block 25 is fixedly connected to the bottom end of the fixed frame 21, and the rotating block 25 is rotatably connected to the bottom end of the box body 11, and a handle 24 is fixedly connected to the top of the fixed frame 21, and the bottom of the handle 24 is rotatably connected to the top of the box body 11, and an activated carbon plate 13 is fixedly connected to the inside of the fixed frame 21, and a card block 22 is slidably connected to the inside of the fixed frame 21, and a spring 23 is fixedly connected to one side of the card block 22, and the end of the spring 23 is fixedly connected to the inside of the fixed frame 21, and a card slot 26 is opened inside the box body 11, and the card block 22 is carded inside the card slot 26.

[0035] In this embodiment, after the device is used for a long time, the side of the activated carbon plate 13 close to the air inlet pipe 12 has little adsorption space due to long-term adsorption, but the side of the activated carbon plate 13 away from the air inlet pipe 12 still has a certain amount of surplus adsorption space. If the user needs to turn over the activated carbon plate 13, the user can rotate the handle 24 180 degrees. During the rotation of the handle 24, since the block 22 is connected to the inside of the slot 26, and the end of the block 22 and the outline of the slot 26 are both arc-shaped, when the handle 24 is rotated to drive the fixed frame 21 to rotate, the inner wall of the slot 26 will squeeze the edge of the block 22. After the edge of the block 22 is squeezed, the block 22 will move toward the fixed frame 21. The spring 23 will be elastically deformed and compressed at this time. As the fixed frame 21 rotates, when the card block 22 is completely disengaged from the inside of the card slot 26, the spring 23 in the elastically compressed state will rebound, driving the card block 22 to reset. When the fixed frame 21 is about to rotate 180 degrees, the edge of the card block 22 will touch the inner wall of the box body 11 again. At this time, the end of the card block 22 will slide toward the fixed frame 21 after being squeezed by the inner wall of the box body 11. At this time, the spring 23 will be elastically deformed again. When the fixed frame 21 is rotated to 180 degrees, the spring 23 in the elastically deformed state rebounds, driving the card block 22 to be clamped into the inside of the card slot 26 again, thereby completing the flipping and clamping of the fixed frame 21.

[0036] Example 2: Please refer to Figure 1-5 An air inlet pipe 12 is fixedly connected to the outside of the box body 11, a connecting pipe 14 is fixedly connected to the outside of the box body 11, a drying barrel 15 is fixedly connected to the top of the base 1, the top of the connecting pipe 14 is fixedly connected to the top of the outer wall of the drying barrel 15, a drying pipe 16 is fixedly connected to the inside of the drying barrel 15, an air outlet pipe 17 is fixedly connected to the bottom of the outer wall of the drying barrel 15, and a fan 18 is fixedly connected to the inside of the box body 11.

[0037] In this embodiment, after the waste gas from the production of flexible circuit boards enters the interior of the box 11 from the air inlet pipe 12, the exhaust gas will be moved toward the interior of the drying barrel 15 through the operation of the fan 18, and then the activated carbon plate 13 can adsorb and filter the impurities in the exhaust gas. After the adsorbed exhaust gas enters the interior of the drying barrel 15, the drying pipe 16 inside the drying barrel 15 will dry the filtered exhaust gas, and the dried exhaust gas can be collected through the exhaust pipe 17.

[0038] The working principle of the utility model is: before use, the user first checks whether the device is damaged. After confirming that the device is not damaged, the exhaust gas from the production of flexible circuit boards enters the interior of the box body 11 from the air inlet pipe 12, and the exhaust gas is moved toward the interior of the drying barrel 15 through the operation of the fan 18. Then, the activated carbon plate 13 can adsorb and filter impurities in the exhaust gas. After the exhaust gas after adsorption enters the interior of the drying barrel 15, the drying pipe 16 inside the drying barrel 15 will dry the filtered exhaust gas, and the dried exhaust gas can be collected through the exhaust pipe 17.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
