Description

Technical Field

[0001] This utility model relates to the technical field of filtration, specifically a novel activated carbon filtration device. Background Technology

[0002] Activated carbon is a commonly used material in people's production and daily life. Thanks to its special processing materials and technology, activated carbon has a large specific surface area and a large number of tiny pores inside, which gives it excellent adsorption capacity. It can be used for decolorization and adsorbing surrounding odors, bacteria, toxic gases, etc.

[0003] For example, a novel activated carbon filtration device with authorization announcement number "CN207871833U" solves the problem of insufficient utilization of some activated carbon in existing novel activated carbon filtration devices. The above-mentioned device eliminates the interference of moisture and dust on activated carbon filtration, has a long service life of activated carbon, high adsorption efficiency for target substances, and can be reused. However, considering that existing novel activated carbon filtration devices improve sealing performance with multiple sealing rings, they do not have a clearly defined structure for easy disassembly. Replacing the second activated carbon filter layer may require disassembling many parts, resulting in low maintenance convenience. After long-term use, the filtration effect may decrease due to adsorption saturation and differences in replacement and maintenance, and the stability of the filtration effect will deteriorate. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing activated carbon filter devices, such as low maintenance convenience, decreased filtration effect due to differences in replacement and maintenance, and deterioration of filtration effect stability. Therefore, a new type of activated carbon filter device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel activated carbon filtration device, comprising a shell and an air outlet pipe, wherein the inner wall of the shell is connected to the air outlet pipe, characterized in that: the upper end of the shell is threadedly connected to a cover, the inner wall of the middle part of the cover is connected to an air inlet pipe, and an installation mechanism is connected inside the shell.

[0006] This design allows for quick disassembly via the threaded connection between the cover and the outer casing, facilitating regular inspection and maintenance of the internal mounting mechanism and various filter components. The connection between the air inlet pipe and the cover ensures that the gas to be filtered can stably enter the device, effectively guaranteeing a smooth filtration process.

[0007] Preferably, the mounting mechanism includes a plug, the lower end of which is fixedly connected to the outer shell, the upper end of which is fixedly connected to the mounting bracket, and the inner wall of the mounting bracket is fixedly connected to the first HEPA filter layer.

[0008] This setup provides a stable support foundation for the mounting frame through the fixed connection between the insert and the outer shell. The first HEPA filter layer fixed to the inner wall of the mounting frame can efficiently filter the gas entering the device, effectively intercepting fine particulate matter in the air, laying a good foundation for subsequent activated carbon adsorption treatment. This structural design not only ensures the stability of the mounting frame, but also fully utilizes the filtration efficiency of the first HEPA filter layer.

[0009] Preferably, the inner wall of the cover is machined with a groove, and the inner wall of the mounting bracket is connected to an activated carbon filter mechanism.

[0010] The groove on the inner wall of the cover facilitates the application of rotational force for turning, further improving the convenience of installation and disassembly.

[0011] Preferably, the activated carbon filtration mechanism includes a first connecting frame, the outer wall of the first connecting frame being fitted with the mounting frame, the inner wall of the first connecting frame being fixedly connected to the first activated carbon filter layer, the inner wall of the first connecting frame being fitted with a second connecting frame, and the inner wall of the second connecting frame being fixedly connected to the second activated carbon filter layer.

[0012] This design, with the first connecting frame and the mounting frame fitting together, ensures the stable placement of the activated carbon filter mechanism within the mounting frame. The first activated carbon filter layer fixed to the inner wall of the first connecting frame can perform a second-level deep adsorption of odors and some toxic gases in the gas. Meanwhile, the second connecting frame, which is fitted to the inner wall of the first connecting frame, and the second activated carbon filter layer fixed to its inner wall, can perform the first-level adsorption treatment of the gas. The combined design of the two activated carbon filter layers significantly improves the adsorption efficiency of harmful substances in the gas, ensuring that the filtered gas is cleaner.

[0013] Preferably, the inner wall of the second connecting frame is fitted with the third connecting frame, and the inner wall of the third connecting frame is fixedly connected to the second HEPA filter layer.

[0014] This design allows the second and third connecting frames to fit together, enabling the third connecting frame to be securely installed inside the second connecting frame. The second HEPA filter layer fixed to the inner wall of the third connecting frame can further refine the gas after it has been filtered by activated carbon.

[0015] Preferably, the inner wall of the third connecting frame is in contact with the drying filter cartridge, and the inner wall of the drying filter cartridge is fixedly connected to the primary filter layer.

[0016] This feature ensures the stable installation of the dry filter cartridge within the third connecting frame, as the pre-filter layer fixed to the inner wall of the dry filter cartridge performs preliminary filtration on the gas entering the device, effectively removing larger particulate impurities and preventing them from clogging the subsequent HEPA and activated carbon filter layers, thereby extending the service life of each filter component.

[0017] The novel activated carbon filtration device proposed in this utility model has the following advantages: the shell and cover are connected by threads, which facilitates quick disassembly and maintenance; the insert, mounting bracket and multi-layer connecting bracket enable stable nesting installation of each filtration component; in terms of filtration, a pre-filter layer is added to remove large particles first to avoid clogging of subsequent layers; two HEPA filter layers and two activated carbon filter layers are set to finely filter small particles and adsorb harmful substances in stages; it is convenient to perform regular maintenance on each component, extend the overall service life of the device and ensure stable filtration effect.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Please see Figure 1-6 In this embodiment, a novel activated carbon filter includes a housing 1 and an air outlet pipe 2. The inner wall of the housing 1 is connected to the air outlet pipe 2. The feature is that the upper end of the housing 1 is threadedly connected to a cover 3, the inner wall of the middle part of the cover 3 is connected to an air inlet pipe 4, and an installation mechanism 5 is connected inside the housing 1.

[0027] The mounting mechanism 5 includes a plug 501, the lower end of which is fixedly connected to the outer shell 1, the upper end of which is fixedly connected to the mounting bracket 502, and the inner wall of the mounting bracket 502 is fixedly connected to the first HEPA filter layer 503.

[0028] The outer shell 1 and the cover 2 are threaded together for easy and quick disassembly and maintenance. The insert block 501, the mounting bracket 502 and the multi-layer connecting bracket enable stable nesting installation of each filter component. In terms of filtration, a pre-filter layer is added to remove large particles first to avoid clogging of subsequent layers. Two HEPA filter layers and two activated carbon filter layers are set to finely filter small particles and adsorb harmful substances in stages. This facilitates regular maintenance of each component, extends the overall service life of the device and ensures stable filtration effect.

[0029] The inner wall of the cover 3 is machined with a groove 6. The inner wall of the mounting bracket 502 is connected to an activated carbon filter mechanism 7. The activated carbon filter mechanism 7 includes a first connecting bracket 701. The outer wall of the first connecting bracket 701 is in contact with the mounting bracket 502. The inner wall of the first connecting bracket 701 is fixedly connected to the first activated carbon filter layer 702. The inner wall of the first connecting bracket 701 is in contact with a second connecting bracket 703. The inner wall of the second connecting bracket 703 is fixedly connected to the second activated carbon filter layer 704.

[0030] The inner wall of the second connecting frame 703 is in contact with the third connecting frame 8. The inner wall of the third connecting frame 8 is fixedly connected to the second HEPA filter layer 9. The inner wall of the third connecting frame 8 is in contact with the drying filter cartridge 10. The inner wall of the drying filter cartridge 10 is fixedly connected to the primary filter layer 11.

[0031] Working principle:

[0032] When assembling this novel activated carbon filter device, firstly, the lower end of the insert block 501 is fixed inside the outer casing 1. Then, the mounting bracket 502 is fixedly connected to the upper end of the insert block 501. Next, the first HEPA filter layer 503 is installed on the inner wall of the mounting bracket 502. Then, the first connecting bracket 701 is placed inside the mounting bracket 502 and fitted together. The first activated carbon filter layer 702 is installed on the inner wall of the first connecting bracket 701. Then, the second connecting bracket 703 is fitted to the inner wall of the first connecting bracket 701 and the second activated carbon filter layer 704 is installed. Subsequently, the third connecting bracket 8 is fitted to the inner wall of the second connecting bracket 703 and the second HEPA filter layer 9 is installed. Then, the drying filter cartridge 10 is fitted to the inner wall of the third connecting bracket 8 and the primary filter layer 11 is installed. Finally, the cover 3 is threaded to the outer casing 1, so that the air inlet pipe 4 is connected to the inner wall of the middle part of the cover 3 and the air outlet pipe 2 is connected to the inner wall of the outer casing 1, thus completing the assembly.

[0033] During use, the gas to be filtered enters the device through the inlet pipe 4, first passing through the pre-filter layer 11, which can effectively remove larger particulate impurities in the gas and prevent them from clogging subsequent filter layers. Then, the gas passes through the second HEPA filter layer 9 for further fine filtration, and then passes through the second activated carbon filter layer 704 and the first activated carbon filter layer 702 in sequence. These two activated carbon filter layers can deeply adsorb odors and some toxic gases in the gas. Finally, the gas passes through the first HEPA filter layer 503 for further filtration, and the clean gas is discharged from the outlet pipe 2.

[0034] In terms of maintenance, since the cover 3 is threaded to the outer shell 1 and the inner wall of the cover 3 has a groove 6, the cover 3 can be easily unscrewed by applying rotational force through the groove 6, which facilitates the inspection and replacement of the internal installation mechanism 5 and each filter component. Regular maintenance can ensure the filtration efficiency of each filter layer, extend the service life of the device, and ensure that the filtered gas always remains clean.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
