Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a filter material replacement device for the fresh air inlet of an industrial rotary dehumidifier. Background Technology

[0002] In the industrial manufacturing sector, humidity control is crucial for product quality and production efficiency. Rotary dehumidifiers are highly efficient and environmentally friendly dehumidification devices. Using a rotating wheel as a carrier, they absorb and remove moisture from the air, thereby reducing humidity. These dehumidifiers are widely used in various fields, including industry, commerce, and homes, and their superior performance is particularly evident in environments with high humidity requirements.

[0003] Rotary dehumidifiers typically use filter cotton, filter cloth, or filter screen (hereinafter collectively referred to as filter media) to filter air and adsorb dust. After adsorbing a certain amount of dust, the filter media needs to be replaced in a timely manner to ensure its filtration function. This is especially true in industrial environments, where the replacement frequency of dehumidifier filter media is even higher. However, replacing the filter media in existing rotary dehumidifiers is quite cumbersome, requiring the dehumidifier to be stopped and the filter device removed for replacement, resulting in high maintenance costs.

[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 1-3 In this embodiment: A filter replacement device for the fresh air inlet of an industrial rotary dehumidifier is installed at the fresh air inlet of the rotary dehumidifier. The fresh air inlet (not shown in the figure) is rectangular and contains air valves (not shown in the figure). The number of air valves is the same as the number of fresh air inlets. The filter replacement device for the fresh air inlet of this utility model includes an outer frame housing 1, which is a rectangular frame that matches the size of the fresh air inlet. The outer frame housing 1 includes a long side frame 11 and a short side frame 12. Inside, there is a pair of rotating devices 2, including a first rotating shaft 21 and a second rotating shaft 22, both of which are hollow or solid shafts that can be rotatably inserted into the two long side frames 11 of the outer frame housing 1. The first rotating shaft 21 and the second rotating shaft 22 are respectively located on both sides of the air valve, that is, near the two short side frames 12 of the outer frame housing 1. Each end of the first rotating shaft 21 is provided with a rotating handle 23.

[0022] Further as Figure 2 , 3 As shown, two U-shaped grooves 13 are provided on the long side 11 near the rotating handle of the outer frame housing 1, and a round hole 14 is provided on the other long side 11. A detachable cover plate 15 is provided on the upper end of the U-shaped groove 13. One end of the rotating device 2 with the rotating handle 23 is inserted into the U-shaped groove 13, and then the lower end is inserted into the round hole 14. Finally, the cover plate 15 is used to cover and fix it, thus completing the installation of the rotating device 2.

[0023] Further as Figure 1 , 2 As shown in Figure 4, blades 24 are fixedly mounted on the cylindrical surfaces of both the first rotating shaft 21 and the second rotating shaft 22. The blades 24 are trapezoidal plates arranged in a sinusoidal pattern and are evenly distributed on the cylindrical surfaces of the first rotating shaft 21 and the second rotating shaft 22 located inside the outer frame housing 1. A gap is left between the uppermost blade 24 and the frame of the outer frame housing 1 to facilitate the installation of the first rotating shaft 21 and the second rotating shaft 22. The first rotating shaft 21 and the second rotating shaft 22 are used to install filter media, and the blades 24 can play a certain role in fixing the filter media.

[0024] Further as Figure 1 , 2 As shown in Figure 3, the outer frame housing 1 is also provided with a hanging plate 3. The hanging plate 3 is L-shaped, and the short side of the front L is a hook. Two or more hanging plates 3 can be set, and the number is determined according to the size of the air valve.

[0025] The working principle of this utility model is as follows: In this embodiment, after the filter material is wound around the first rotating shaft 21, the cover plate 15 is opened, and the first rotating shaft 21 is inserted from the side opening of the U-shaped groove 13. The insertion position is between the uppermost blade 24 and the rotating handle 23. After insertion, the first rotating shaft 21 is inserted downwards so that the lower end of the first rotating shaft 21 is inserted into the corresponding round hole 14. The cover plate 15 is then closed and locked, thus completing the installation of the first rotating shaft 21. The second rotating shaft 22 does not wind the filter material and is installed in another U-shaped groove 13 of the outer frame housing 1 in the same way. When in use, the filter material of the first rotating shaft 21 is pulled out and then rotated and wound up by the second rotating shaft 22. When replacing the filter media, there is no need to remove the outer frame 1. Simply shake the second rotating shaft 22 to pull the dirty filter media out of the fresh air inlet of the air valve and roll it up, which will drive the first rotating shaft 21 to rotate until the clean filter media is placed at the fresh air inlet of the air valve, thus achieving the function of quick filter replacement at the fresh air inlet. When cleaning the filter, the filter replacement device needs to be removed. While rotating the first rotating shaft 21, the dirty filter media surface can be blown or washed to clean the filter media.
