Description

Technical Field

[0001] This utility model belongs to the field of disinfection, specifically relating to a convenient disinfection device. Background Technology

[0002] With the advent of the information age, the number and types of archives are constantly increasing, placing higher demands on their preservation and management. Traditional methods of archival preservation are often ineffective in preventing the aging and damage of archival materials, especially in humid, dusty, or microbial environments, where the quality of preservation can be severely affected.

[0003] Currently, archival disinfection mainly relies on traditional methods such as ultraviolet disinfection, ozone disinfection, and chemical disinfection lamps. However, these methods have many limitations. For example, while ultraviolet disinfection can kill some microorganisms, its penetration power is limited, making it difficult to achieve deep disinfection inside the archives. Ozone disinfection, although effective, is irritating to humans and requires prolonged ventilation afterward, making the process complex and posing safety hazards. As for chemical disinfection, it easily leaves chemical residues, which can damage archival materials and pollute the environment. Therefore, traditional disinfection methods have various drawbacks, and the disinfection equipment using these methods is often complex in structure, making it difficult for users to operate and increasing subsequent maintenance costs. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a convenient disinfection device with a simple overall structure, convenient and quick operation, and reduced maintenance costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a convenient disinfection device, including a cabinet and an air extraction module, a heat dissipation module, a drying module, a separation module and a filter module installed in the cabinet.

[0006] One end of the air extraction module is connected to the outside air, and the other end is connected to the heat dissipation module so that the air drawn in is cooled by the heat dissipation module.

[0007] The drying module and the separation module are located on one side of the heat dissipation module. The drying module is connected to the heat dissipation module and is used to dry the cooled air and deliver it to the separation module. One side of the separation module is connected to the drying module, and the other side is connected to the filter module to deliver the air after oil-water separation to the filter module.

[0008] At least one set of filter modules is provided. The outlet end of the filter module, which is away from the separation module, passes through the cabinet and is connected to the outside. A membrane separator is provided in the filter module. The membrane separator can separate nitrogen from the air after oil-water separation and discharge it to the outside of the cabinet to achieve disinfection of objects.

[0009] In the aforementioned convenient disinfection device, the air extraction module includes a pre-filter and a compressor pump. The pre-filter is connected to the air inlet of the compressor pump, so that when the compressor pump draws in external air, it can be filtered by the pre-filter and then transferred to the heat dissipation module.

[0010] In the aforementioned convenient disinfection device, the bottom of the cabinet is also equipped with rollers and anti-slip blocks. The rollers are used to move the cabinet, and the anti-slip blocks can restrict the rollers from rotating relative to the frame.

[0011] In the aforementioned convenient disinfection device, the separation module includes a mounting bracket and an oil-water separator. The mounting bracket is connected to the cabinet, and the oil-water separator has an air inlet and an air outlet. The air inlet is connected to the drying module, and the air outlet is connected to the filter module.

[0012] In the aforementioned convenient disinfection device, there is a height difference between the air inlet and the top wall of the drying module.

[0013] In the aforementioned convenient disinfection device, a cooling fan is provided inside the heat dissipation module, which is used to cool the air inside the heat dissipation module.

[0014] In the aforementioned convenient disinfection device, the mounting bracket has a supporting rib, and a fastening block is detachably connected to the supporting rib. The filter module also includes a multi-layer filter on which the membrane separator is installed, and the fastening block is used to restrict the multi-layer filter to a horizontal position.

[0015] In the aforementioned convenient disinfection device, the side wall of the cabinet is also provided with an installation hole, through which a pipe connected to the outlet end of the filter module can pass to discharge nitrogen gas to the external object to be disinfected.

[0016] In the aforementioned convenient disinfection device, a foldable tent is also provided on the outside of the cabinet. A transmission pipe is connected between the tent and the mounting hole to disinfect the enclosed space inside the tent.

[0017] In the aforementioned convenient disinfection device, the side wall of the cabinet is further provided with an inner groove, and the mounting hole is provided on the inner wall of the inner groove to connect the pipe and the transmission pipe.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The equipment integrates an air extraction module, a heat dissipation module, a drying module, a separation module and a filtration module. Through the coordinated work of these modules, the complete process from air extraction to high-purity nitrogen separation is realized. At the same time, the membrane separation technology can accurately separate nitrogen from the treated air. Nitrogen disinfection can effectively kill various bacteria, viruses and other microorganisms. It is safe and pollution-free. It can be seen that the overall structure of the nitrogen disinfection equipment is relatively simple, which brings convenience to users during operation and reduces subsequent maintenance costs.

[0020] (2) The foldable tent on the outside of the cabinet can be quickly deployed according to actual needs and is suitable for disinfection tasks in different scenarios. The enclosed tent space provides an extra layer of safety, protecting the items being disinfected from external interference and ensuring the safety of people around. In addition, the tent can be folded when not in use to reduce the space occupied. Moreover, since it is a local enclosed space for disinfection, it reduces the resource consumption required for overall environmental disinfection.

[0021] (3) The presence of the inner groove makes the transmission pipe and pipeline more intuitive and simple in the connection hole, reduces possible human error during connection, improves work efficiency, and at the same time, the inner groove can protect the installation hole from the influence of the external environment, such as dust and moisture, and extend the service life of the equipment.

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0034] Example 1:

[0035] like Figures 1 to 3 As shown, this utility model discloses a convenient disinfection device, including a cabinet 1 and an extraction module 2, a heat dissipation module 3, a drying module 4, a separation module 5, and a filter module 6 installed inside the cabinet 1. One end of the extraction module 2 is connected to the outside air, and the other end is connected to the heat dissipation module 3 to cool the extracted air. The drying module 4 and the separation module 5 are located on one side of the heat dissipation module 3. The drying module 4 is connected to the heat dissipation module 3 to dry the cooled air and deliver it to the separation module 5. One side of the separation module 5 is connected to the drying module 4, and the other side is connected to the filter module 6 to deliver the oil-water separated air to the filter module 6. At least one set of filter modules 6 is provided. The outlet end of the filter module 6 away from the separation module 5 passes through the cabinet 1 and connects to the outside. A membrane separator is installed inside the filter module 6, which can separate nitrogen from the oil-water separated air and discharge it outside the cabinet 1 to achieve disinfection of objects.

[0036] This plan primarily aims to disinfect archival materials using nitrogen gas. Specifically, for example... Figures 1 to 3As shown, when the cabinet 1 is located in the storage space, the air extraction module 2 can draw air from the external environment and introduce it into the heat dissipation module 3 through pipes. The heat dissipation module 3 will cool the air drawn in, and the temperature of the cooled air will be reduced, which will reduce the negative impact of high temperature in subsequent processing (such as reduced drying efficiency or decreased membrane separator performance). As the drying module 4 receives the cooled air, it will further remove the moisture in the air, avoiding the impact of water vapor on the subsequent separation and filtration processes. In particular, it will protect the membrane separator from damage by the humid environment and extend its service life. The dried air is then sent to separation module 5 for oil-water separation to remove oil and other impurities from the air, reducing contaminants that may affect the performance of the membrane separator and ensuring a stable output of high-purity nitrogen. Finally, this embodiment includes at least one set of filter modules 6 near the top of cabinet 1 (three sets are used in this embodiment; however, this number is not limited to one type and can be adjusted according to actual needs). Each filter module 6 contains a membrane separator (not shown in the figure). The application of the membrane separator makes the nitrogen separation process more precise and efficient, ensuring high nitrogen purity (≥99%), meeting the nitrogen purity requirements for archival disinfection. High-purity nitrogen creates a low-oxygen environment, effectively inhibiting or killing microorganisms, ensuring the safety and effectiveness of disinfection. Furthermore, nitrogen is non-toxic, harmless, and does not chemically react with archival materials, protecting the original state of the archives and being friendly to operators and the environment.

[0037] It should be noted that the disinfection equipment uses membrane separation technology (the working principle is the same as that in the existing technology, and will not be described in detail here). The heat dissipation module 3, the drying module 4 and the separation module 5 provide a guarantee for the purity of the nitrogen separated by the membrane separator, regulate the air composition in the environment, reduce or eliminate the oxygen environment required for the survival of microorganisms, and achieve the purpose of disinfection or inhibition of microbial growth.

[0038] The air extraction module 2 includes a primary filter 20 and a compressor pump 21. The primary filter 20 is connected to the air inlet of the compressor pump 21, so that when the compressor pump 21 draws in external air, it can be filtered by the primary filter 20 and then transferred to the heat dissipation module 3.

[0039] like Figure 2 and Figure 3As shown, when the equipment starts, the compressor pump 21 begins to work, drawing air from the external environment. The air first enters the pre-filter 20, where larger particles are blocked and collected, thus achieving a preliminary screening effect for impurities. This prevents these impurities from entering the compressor pump 21 and other internal components, reducing the risk of mechanical wear and contamination. This not only extends the service life of the compressor pump 21 and other components but also reduces maintenance costs. The clean air after preliminary filtration is then drawn into the compressor pump 21 and transported through pipelines to the heat dissipation module 3 for cooling.

[0040] The heat dissipation module 3 is equipped with a heat dissipation fan 30, which is used to cool the air inside the heat dissipation module 3.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, the heat dissipation module 3 can accept compressed air from the compression pack. A finned heat sink (not shown in the figure) is installed in the cavity of the heat dissipation module 3. With the rotation of the cooling fan 30, it promotes the uniform flow of air throughout the heat dissipation module 3 and avoids local overheating. This ensures that all the air passing through can be effectively cooled, improves the consistency and stability of the overall processing, and provides more ideal conditions for subsequent processing (lower temperature air is easier to dry, thereby reducing the workload and energy consumption of the drying module 4).

[0042] Preferably, the drying module 4 in this embodiment is equipped with a highly efficient desiccant or condenser (not shown in the figure) to remove moisture from the air and ensure that the air supplied to the separation module 5 is in a dry state.

[0043] The separation module 5 includes a mounting bracket 50 and an oil-water separator 51. The mounting bracket 50 is connected to the cabinet 1. The oil-water separator 51 has an air inlet 510 and an air outlet 511. The air inlet 510 is connected to the drying module 4, and the air outlet 511 is connected to the filter module 6.

[0044] like Figures 1 to 3As shown, the dried air is sent from the drying module 4 through a pipe to the air inlet 510 of the oil-water separator 51. The oil-water separator 51 is internally designed with multi-layer filter elements or other high-efficiency separation structures, which can effectively remove oil and other impurities from the air. These separation structures can capture fine droplets and solid particles in the air, preventing them from entering the subsequent filter module 6. Therefore, the design of the oil-water separator 51 effectively removes oil and other impurities from the air, ensuring that the air entering the filter module 6 is highly clean. This is crucial for protecting the membrane separator, as any contaminants can affect its performance and lifespan. The clean air after oil-water separation is discharged from the air outlet 511 of the oil-water separator 51 and transported through a pipe to the filter module 6 for further processing.

[0045] Preferably, such as Figure 2 As shown, in this embodiment, there is a height difference between the air inlet 510 and the top wall of the drying module 4. That is, the air inlet 510 is higher than the air outlet of the drying module 4. This is mainly because there may be a small amount of condensate that has not been completely removed inside the drying module 4. If the air inlet 510 and the top wall of the drying module 4 are at the same height, this condensate may enter the oil-water separator 51 along with the air. By setting a height difference, the condensate is more likely to drip naturally down the inner wall of the drying module 4 to the bottom, reducing the risk of condensate flowing into the separator 5 with the air.

[0046] like Figure 2 and Figure 3 As shown, it is precisely because of the aforementioned primary filter 20, cooling fan 30, drying module 4, and oil-water separator 51 that a series of filtration, cooling, drying, and separation processes are performed on the air. This results in drier and cleaner air, reducing the risk of contamination to the membrane separator, lowering maintenance frequency and replacement costs. Simultaneously, it ensures that the nitrogen extracted from the air by the membrane separator is pure enough for stable disinfection of archival materials, improving the long-term reliability of the equipment. It should be noted that membrane separation technology refers to the selective separation of a mixture of molecules of different particle sizes at the molecular level when passing through a semi-transparent membrane. The membrane is a material with selective separation capabilities. The process of separating, purifying, and concentrating different components of a liquid using the selective separation capabilities of a membrane is called membrane separation. It differs from traditional filtration in that membranes can separate at the molecular level, and this process is a physical process that does not require phase changes or the addition of additives.

[0047] The side wall of the cabinet 1 is also provided with a mounting hole 12. The pipe connected to the outlet end of the filter module 6 can pass through the mounting hole 12 to discharge nitrogen gas to the external object to be disinfected.

[0048] like Figure 2 and Figure 3As shown, the mounting hole 12 in this embodiment can fix and guide the pipeline, ensuring that the nitrogen gas extracted from the membrane separator can be accurately discharged to the archival materials for disinfection. Moreover, the design of the mounting hole 12 allows the pipeline to be led out directly from the side wall of the cabinet 1, reducing the extra space occupied, maintaining the overall compactness of the equipment, and facilitating movement and deployment.

[0049] The mounting bracket 50 has a support rib 500, and a fastening block 501 is detachably connected to the support rib 500. The filter module 6 also includes a multi-layer filter 60 with a membrane separator installed. The fastening block 501 is used to restrict the multi-layer filter 60 to a horizontal position.

[0050] like Figure 2 As shown, in this embodiment, three multi-layer filters 60 are equidistantly mounted on the support rib 500. Each multi-layer filter 60 includes the aforementioned membrane separator. After the oil-water separator 51 removes oil and other impurities from the air, purified air can be delivered to the multi-layer filter 60. Figure 2 In the process of transporting air from left to right by the multi-layer filter 60, the air passes through a membrane separator to separate high-purity nitrogen, which is then discharged to the external archival materials through a pipe connected to the mounting hole 12. To ensure the stability of the above operation, this embodiment uses the design of support ribs 500 and fastening blocks 501 to provide stable support for the multi-layer filter 60, preventing displacement or tilting during operation, ensuring the uniformity of airflow through each filter layer, improving the filtration effect, and avoiding local overload or efficiency reduction caused by tilting. It should be noted that the fastening block 501 adopts a detachable design (screws or other fasteners can be used as alternatives), allowing the multi-layer filter 60 to be easily removed from the mounting bracket 50, simplifying the maintenance and replacement process and reducing downtime.

[0051] The bottom of the cabinet 1 is also equipped with rollers 10 and anti-slip blocks 11. The rollers 10 are used to move the cabinet 1, and the anti-slip blocks 11 can restrict the rollers 10 from rotating relative to the frame.

[0052] like Figure 1 and Figure 2 As shown, all modules in this embodiment are integrated within the cabinet 1. By installing casters 10 at the bottom of the cabinet 1, the entire disinfection equipment can be quickly and conveniently moved to a designated location for nitrogen disinfection according to actual usage needs. This high flexibility makes it suitable for applications requiring frequent changes in work location, such as archives and libraries. The anti-slip block 11 effectively restricts the rotation of the casters 10 after the equipment reaches the designated position, ensuring the equipment remains stable during operation and preventing accidental movement that could affect operation or create safety hazards.

[0053] More preferably, in this embodiment, an inner groove 14 is formed on the side wall of the cabinet, such as... Figure 2 As shown, the mounting hole is located on the inner wall of the recess 14. In other words, the connection between the pipe connected to the outlet of the filter module and the mounting hole is conveniently hidden within the recess 14. This ensures the overall simplicity and aesthetics of the cabinet while saving space, facilitating storage and transportation, and effectively protecting the mounting hole from external environmental influences such as dust and moisture, thus extending the service life of the equipment. Preferably, the recess 14 in this embodiment can be designed with a sealing structure (not shown in the figure), such as a rubber ring or other form of seal. This helps improve the sealing between the mounting hole and the transmission pipe, prevents nitrogen leakage, and ensures the disinfection effect.

[0054] Example 2:

[0055] This second embodiment is based on the structure of the first embodiment described above, with corresponding improvements, specifically, as follows: Figure 1 As shown, in this embodiment two, a foldable tent 7 is also provided outside the cabinet. When the tent 7 is in the open state, the tent 7 and the mounting hole can be sealed together through a transmission pipe (not shown in the figure). In this way, the nitrogen gas extracted from the membrane separator can be accurately discharged into the tent 7 through the transmission pipe, thereby realizing the disinfection of the archival materials inside the tent 7. It can be seen that the foldable tent 7 can be quickly deployed according to actual needs, suitable for disinfection tasks in different scenarios (such as other fields: medical facilities, food processing areas, etc.), and the enclosed space of the tent 7 provides an additional safety layer, protecting the items being disinfected from external interference, and also ensuring the safety of surrounding personnel. Moreover, since it is a local sealed disinfection, it effectively reduces the resource consumption required for overall environmental disinfection. It should be noted that when the tent 7 is not in use, this embodiment two can fold the tent 7 (the folding structure of the tent 7 is the same as the structure and principle in the prior art, and will not be described in detail here), reducing the space occupied.

[0056] It should be noted that in this embodiment, the various modules can be interconnected via pipes (not shown in the figure) to allow external air to undergo a series of filtration, cooling, drying, and separation processes before being extracted into high-purity nitrogen gas through a membrane separator, ensuring stable disinfection of archival materials. Preferably, in this embodiment, a central control screen 13 can also be installed on the side wall of the cabinet 1. This central control screen 13 can control the normal operation of each module in the disinfection equipment, thereby ensuring the stability of nitrogen disinfection of archives.
