[0001] This utility model belongs to the field of filter box technology, specifically relating to an activated carbon gas purification filter box. Background Technology

[0002] Gas filters are widely used in metallurgy, chemical industry, petroleum, medicine, food, mining, power and other fields. Air filters are devices that use porous filter materials to capture dust from gas-solid two-phase flow and purify the gas. Gas filtration removes a large number of impurities in the gas to meet the purity requirements and avoid the harm caused by impurities.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN222445688U discloses an "activated carbon filter", which includes a filter cylinder and an elliptical end cap. An activated carbon box is fitted inside the filter cylinder. Four sets of box handles are distributed around the circumference inside the activated carbon box. A feed inlet is provided on the side of the filter cylinder near the bottom. A feed inlet is provided at the top of the elliptical end cap. A drain outlet is provided vertically on the bottom surface of the filter cylinder. A mesh layer is provided on the outer wall of the activated carbon box. The activated carbon box is placed inside the filter cylinder for filtration. The entire filter is mainly used for filtration through the activated carbon box. Operators can easily remove or put the activated carbon box into the filter cylinder, which greatly improves the efficiency of replacing activated carbon.

[0004] While existing activated carbon gas purification filter boxes allow operators to easily remove or insert the activated carbon housing from the filter cylinder, significantly improving the efficiency of activated carbon replacement, in practical applications, because the activated carbon is placed inside a single activated carbon housing, gas preferentially passes through the lower layer of activated carbon, resulting in low utilization of the upper layer. Consequently, when replacing activated carbon, the upper layer is often replaced before it is fully utilized, leading to resource waste. To address these issues, this application proposes an activated carbon gas purification filter box. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an activated carbon gas purification filter box, which features improved activated carbon utilization.

[0008] The filter barrel has three support cylinders arranged vertically inside, and the inner wall of each support cylinder is circumferentially fixedly connected to a support plate.

[0009] Each support cylinder is detachably mounted with a filter frame via the support plate, the filter frame being used to support the activated carbon layer.

[0017] In this invention, the activated carbon gas purification filter box achieves uniform contact between the gas and the activated carbon layer layer by layer, thereby improving the utilization rate of activated carbon. Compared with the prior art, the activated carbon gas purification filter box in this application avoids the problem of premature replacement of the upper activated carbon due to low utilization, effectively saving resources.

[0027] 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.

[0028] Example

[0029] Please see Figures 1-6 The present invention provides the following technical solution: an activated carbon gas purification filter box, including a filter box body 1, and a detachable top cover 2 on the top of the filter box body 1;

[0030] A support frame 3 is fixedly installed inside the filter box 1, and a filter bucket 4 is placed on the support frame 3.

[0031] Inside the filter barrel 4, three support cylinders 5 are arranged vertically in sequence, and a support plate 6 is fixedly connected to the inner wall of each support cylinder 5.

[0032] Each support cylinder 5 is detachably mounted with a filter frame 7 via a support plate 6. The filter frame 7 is used to support the activated carbon layer. The diameters of the three support cylinders 5 decrease sequentially from top to bottom, and the diameter of the corresponding filter frame 7 matches the inner diameter of the support cylinder 5. In use, the gas to be filtered is first introduced into the filter box 1 through a pipe. The gas passes through the activated carbon layers in the three support cylinders 5 sequentially for filtration. Since the diameters of the three support cylinders 5 decrease sequentially from top to bottom, the gas can contact the activated carbon layers evenly layer by layer as it passes through, thereby improving the utilization rate of activated carbon. When it is necessary to replace the activated carbon layer, the operator can open the top cover 2, remove the filter bucket 4 from the support frame 3, and then remove the filter frames 7 in the three support cylinders 5 sequentially to replace the activated carbon layer. After replacement, the filter frames 7 and support cylinders 5 are reinstalled back into the filter bucket 4. Finally, the filter bucket 4 is locked onto the support frame 3, and the top cover 2 is closed. The layered design of the activated carbon layer ensures that the gas can pass through each layer of activated carbon evenly, effectively avoiding the problem of low utilization rate of the upper activated carbon, thereby maximizing the utilization of resources.

[0033] Preferably, by Figure 2 and Figure 4 As shown, in this embodiment, multiple support rods 13 are provided between multiple support cylinders 5, and the three support cylinders 5 are connected to each other through the support rods 13. The provision of support rods 13 enhances the structural stability between the three support cylinders 5, preventing the support cylinders 5 from shaking or tilting during use, thereby ensuring the stability of the filter frame 7 and the activated carbon layer.

[0034] Preferably, by Figure 4 and Figure 5 As shown in this embodiment, the outer walls of multiple filter frames 7 are provided with two connecting rods 8, and the two connecting rods 8 are symmetrically distributed in an alternating manner. The outer walls of multiple support cylinders 5 are each provided with two L-shaped connecting holes 10, and the two L-shaped connecting holes 10 are symmetrically distributed in an alternating manner. When placing the filter frame 7, the connecting rods 8 can be inserted into the L-shaped connecting holes 10 and rotated at a certain angle so that the limiting piece 9 of the connecting rod 8 is stuck on the outer wall of the support cylinder 5, thereby fixing the filter frame 7. This fixing method is simple to operate, easy to disassemble and install, and improves the efficiency of replacing the activated carbon layer.

[0035] Preferably, by Figure 5 and Figure 6 As shown, in this embodiment, the ends of the multiple connecting rods 8 are provided with limiting pieces 9, the diameter of which is larger than the width of the L-shaped connecting hole 10. By setting the limiting pieces 9, the connecting rods 8 can be prevented from falling out of the L-shaped connecting hole 10, which further improves the stability of the filter frame 7. When the filter frame 7 needs to be disassembled, the connecting rods 8 can be removed from the L-shaped connecting hole 10 by simply rotating them in the opposite direction by a certain angle, thus achieving quick disassembly.

[0036] Preferably, by Figure 5 and Figure 6 As shown, in this embodiment, the outer walls of multiple support cylinders 5 are provided with limiting holes 11 below the L-shaped connecting holes 10, and the limiting holes 11 are vertically connected to the L-shaped connecting holes 10. In further use, when the connecting rod 8 is rotated to the vertical section of the L-shaped connecting hole 10, the outer wall of the connecting rod 8 can be pushed into the limiting hole 11 to achieve double fixation of the connecting rod 8 and improve the stability of the filter frame 7 during installation.

[0037] Preferably, by Figure 3 and Figure 4 As shown, in this embodiment, the three support cylinders 5 are frustum-shaped, and each filter holder 7 has a pull rod 12 at the top center. By setting the pull rod 12, it is convenient for the operator to take the filter holder 7 out of or into the support cylinder 5, which further improves the convenience of replacing the activated carbon layer. Inverting the frustum-shaped support cylinder 5 allows the gas to come into uniform contact with the activated carbon layer layer by layer when it passes through. At the same time, the frustum-shaped design also makes the space at the bottom of the support cylinder 5 gradually decrease, which is conducive to gas compression and filtration, and further improves the filtration efficiency.

[0038] Components not described in detail in this article are existing technologies.

[0039] The working principle and usage process of this utility model: When it is necessary to place three filter frames 7, the diameters of the three support cylinders 5 decrease from top to bottom, so that the three filter frames 7 can be set to different diameters, so that the three filter frames 7 can be respectively locked in the three support cylinders 5, and the diameter of each filter frame 7 matches the inner diameter of the corresponding support cylinder 5.

[0040] When the gas passes through the filter box 1, it will pass through the activated carbon layers on the three filter frames 7 in sequence. Due to the decreasing diameter design of the three support cylinders 5, the gas can contact the activated carbon layers evenly layer by layer, thereby ensuring the full utilization of the activated carbon and avoiding the problem of low utilization rate of the upper activated carbon.

[0041] Meanwhile, the support rod 13 further enhances the structural stability between the three support cylinders 5, making the entire filter device more stable and reliable during use. The design of the connecting rod 8 and the L-shaped connecting hole 10 simplifies the fixing and disassembly process of the filter frame 7 and improves the efficiency of replacing the activated carbon layer.

[0042] In addition, the setting of the limiting hole 11 provides double fixation for the connecting rod 8, which further improves the stability of the filter frame 7 during installation. The design of the pull rod 12 makes it easier for operators to remove or put the filter frame 7 out of the support cylinder 5, further improving the convenience of replacing the activated carbon layer.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
