Technical Field

[0001] This utility model belongs to the field of dehumidification equipment technology, specifically an integrated machine for humidity purification and disinfection in archives. Background Technology

[0002] Fluctuations in temperature and humidity, air pollutants, and the growth of microorganisms can all cause irreversible damage to archives. Paper archives are prone to moisture, deformation, and sticking together in high humidity environments, which can lead to mold growth, blurred handwriting, and brittle paper. Film archives are even more sensitive to humidity. Excessive humidity can cause chemical reactions in the film emulsion layer, resulting in image fading and mold growth. The existing humidity and disinfection integrated machine is used to maintain a stable humidity environment in the archive storage room, purify the air and disinfect and sterilize. By precisely controlling the humidity, it can effectively prevent archives from being damaged by moisture or dryness, filter pollutants in the air to avoid them from eroding the archives, kill bacteria, mold and other microorganisms, prevent microorganisms from damaging the archives, and provide comprehensive protection for the archives. However, in the process of using existing integrated purification and disinfection machines, the airflow crosstalk between the adsorption zone and the regeneration zone causes poor filtration effect of the molecular sieve rotating disk during the filtration of moisture. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides an integrated humidity purification and disinfection machine for archives, which features a dual sealing design of dynamic sealing structure elastic adhesion and negative pressure adsorption, effectively solving the gap crosstalk problem of traditional seals.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated humidity purification and disinfection machine for archives, comprising a shell, a molecular sieve rotating disk, a heating device, an exhaust fan, and an ozone generator. The molecular sieve rotating disk is located in the inner cavity of the shell, and the heating device is located on the back of the molecular sieve rotating disk. The heating device is used to heat the outside air and blow it toward the humid area of ​​the molecular sieve rotating disk. The air discharged from inside the molecular sieve rotating disk is blown toward the ozone generator through the exhaust fan and blown toward the air blowing device at the top of the shell. The molecular sieve rotating disk consists of a molecular sieve body one and a molecular sieve body two, with a central pin fixedly connected at the center of one end of the molecular sieve body one. The device includes a locking pin and two sets of elastic strips fixedly connected to the surface of the locking pin. Each set of elastic strips has a limiting groove on its surface and a fixing frame is fixedly connected to the surface of each elastic strip. The fixing frame has a support strip with the same structure as the limiting groove of the fixing frame slidingly connected inside, and one end of the support strip is fitted into the limiting groove.

[0005] Preferably, the elastic strip has a notch on the side facing the molecular sieve body, wherein the elastic strip slides against the surface of the molecular sieve rotating disk, and an air pump is provided inside the notch. The elastic strip has a through groove inside and is connected to a negative pressure device connector on the surface of the elastic strip. The notch elastic strip is evenly distributed along its length, and the distance between adjacent notches is 12-18 mm. Each notch is connected to the main air channel of the air pump through an independent branch air channel.

[0006] Preferably, the bracket is sleeved on the surface of the center pin, wherein the surface of the center pin is threaded, and a locking pin is threadedly connected to the threaded surface, the locking pin being used to tightly abut the bracket.

[0007] Preferably, the angle between the two sets of elastic strips is 60°, occupying one-third of the surface area of ​​the molecular sieve rotating disk.

[0008] Preferably, the molecular sieve body one and molecular sieve body two have the same structure, both adopting a honeycomb hollow skeleton, with the skeleton surface coated with a molecular sieve adsorption coating, and the coating pore size of molecular sieve body one is larger than that of molecular sieve body two.

[0010] Preferably, the ozone generator is fixed to the air outlet duct of the outer casing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model effectively solves the problem of gap crosstalk in traditional seals by adopting a dynamic sealing structure with elastic adhesion and negative pressure adsorption dual sealing design, reducing the crosstalk rate to below 1% and improving dehumidification efficiency; at the same time, the wear compensation adjustment structure of the elastic strip extends the service life of the sealing component and reduces maintenance costs.

[0012] 2. High dehumidification efficiency: It adopts a gradient adsorption structure with a dual molecular sieve body, combined with a honeycomb skeleton and adsorption coatings with different pore sizes, which prolongs the contact time between air and adsorption material, improves the single adsorption efficiency, and can meet the dehumidification needs of high humidity environments.

[0013] Instead of conventional ultraviolet disinfection and chlorine-containing disinfectant, an ozone generator is used. These methods can easily corrode paper during use, and ultraviolet light has poor penetration and can only be used for surface disinfection. Combining dehumidification and disinfection can inhibit the growth of microorganisms at the source. By first reducing the ambient humidity and destroying the living conditions of microorganisms, disinfection can be carried out, which can effectively kill residual microorganisms and improve the quality of the output air.

Detailed Implementation

[0016] 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.

[0017] like Figures 1 to 6 As shown, this utility model provides an integrated humidity purification and disinfection machine for archives, including a shell 1, a molecular sieve rotating disk 2, a dynamic sealing structure 3, a heating device 4, an exhaust fan 5, and an ozone generator 6. The molecular sieve rotating disk 2 is located in the inner cavity of the shell 1, and the heating device 4 is located on the back of the molecular sieve rotating disk 2. The heating device 4 is used to heat the outside air and blow it towards the humid area of ​​the molecular sieve rotating disk 2. The air discharged from the inside of the molecular sieve rotating disk 2 is blown towards the ozone generator 6 through the exhaust fan 5 and blown towards the air blowing device at the top of the shell 1. The molecular sieve rotating disk 2 is composed of a molecular sieve body 1 21 and a molecular sieve body 22, and a central pin 23 is fixedly connected to the center of one end of the molecular sieve body 1 21. The dynamic sealing structure 3 includes a bracket 33 and two sets of elastic strips 34 fixedly connected to the surface of the bracket 33. Limiting grooves 31 are respectively opened on the surface of the dynamic sealing structure 3. Fixing frames 37 are fixedly connected to the surface of the elastic strips 34. The internal of the fixing frame 37 is a support strip 38 with the same structure as the horizontal groove of the fixing frame 37. One end of the support strip 38 is embedded in the limiting groove 31 to support the notch 35 and ensure that it always fits the surface of the molecular sieve rotating disk 2. When the molecular sieve rotating disk 2 rotates, the elastic strip 34 deforms slightly with the contact surface, blocking more than 95% of the direct airflow interference, causing the notch 35 to produce intermittent motion when rotating on the surface of the molecular sieve rotating disk 2.

[0018] Specifically, the elastic strip 34 has a notch 35 on the side facing the molecular sieve body 21. The elastic strip 34 slides against the surface of the molecular sieve rotating disk 2. An air suction pump 36 is installed inside the notch 35. A through groove is installed inside the elastic strip 34 and connected to the negative pressure device connector on the surface of the elastic strip 34. The notches 35 and elastic strip 34 are evenly distributed along their length. Each notch 35 is connected to the main air channel of the air suction pump 36 through an independent branch air channel. When the molecular sieve embedded in the molecular sieve body 21 approaches the surface of the notch 35, the negative pressure will actively adsorb the cross-flow air in the gap and introduce it into the vacuum pipe for discharge, preventing it from entering the other side of the air zone.

[0019] Furthermore, the bracket 33 is sleeved on the surface of the central pin 23, wherein the surface of the central pin 23 is threaded, and the threaded surface of the central pin 23 is threaded with a locking pin 32, which is used to lock the bracket 33. The bracket 33 is locked by rotating the locking pin 32.

[0020] Furthermore, the angle between the two sets of elastic strips 34 is 60°, occupying one-third of the surface area of ​​the molecular sieve rotating disk 2, with the remaining area at the air inlet. When the adsorbent material inside the air inlet is in contact with moisture for a long time, it needs to be rotated to move the drying area to the air inlet. Through intermittent rotation, the adsorbent material is kept clean for a long time, and moisture is fully adsorbed.

[0021] It is worth noting that molecular sieve body 1 21 and molecular sieve body 2 22 have the same structure, both adopting a honeycomb hollow skeleton. The surface of the skeleton is coated with a molecular sieve adsorption coating. The pore size of the coating of molecular sieve body 1 21 is larger than that of the coating of molecular sieve body 2 22. The two sections use adsorption coatings with different pore sizes. The coarse section with large pores adsorbs quickly, while the fine section with small pores dehumidifies deeply. Combined with the honeycomb skeleton and adsorption coatings with different pore sizes, the contact time between air and adsorption material is extended, improving the single adsorption efficiency and adapting to the dehumidification needs of high humidity environments.

[0022] It is worth noting that the elastic strip 34 is made of high-temperature resistant silicone rubber. The cross-section of the elastic strip 34 is arc-shaped, and the arc is consistent with the arc of the outer circumference of the molecular sieve rotating disk 2, so as to avoid the elastic strip 34 from causing wear on the edge of the molecular sieve rotating disk 2.

[0023] It is worth mentioning that the ozone generator 6 is fixed at the air outlet of the outer casing 1. It uses ozone for disinfection and sterilization. For archives, ultraviolet light can not disinfect the inside of paper documents, while chlorine-containing disinfectants can corrode the paper surface and cannot be preserved for a long time. By using ozone, the ozone is delivered to the required location through the combination of the exhaust gas and ozone, which can disinfect small areas and ensure that corners are penetrated.

[0024] The outer casing 1 is existing technology and will not be described further; this utility model also includes a power supply, controller, and switch, etc., which are not the main technical points of this patent and will not be described further; the "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0025] Working principle: When the outer casing 1 is started, the heating device 4 starts heating. Moist air enters from the air intake grille inside the outer casing 1. The moisture enters the molecular sieve body 21 on the surface of the molecular sieve rotating disk 2. The molecular sieve body 21 is used to adsorb moisture. The filtered air is discharged to the outside. The molecular sieve body 21, after contacting the moisture, becomes continuously damp. The molecular sieve body 22 located behind the molecular sieve body 21 has the same properties and functions as the molecular sieve body 21. It is used to filter external moisture. It adopts two-stage adsorption coatings with different pore sizes. The coarse section with large pores quickly adsorbs moisture, and the fine section with small pores deeply dehumidifies, thereby improving the dehumidification gradient efficiency. With long-term filtration of moisture, the surface of the molecular sieve rotating disk 2 has a lot of moisture. By rotating the molecular sieve rotating disk 2, the moist area rotates to the space between the elastic strips 34. During the rotation, the elastic strips 34 are always in contact with the surface of the molecular sieve rotating disk 2 by the pre-tightening force of the support strips 38. When the molecular sieve rotating disk 2 rotates, the scraper elastic strips 34 deform slightly with the contact surface, blocking more than 95% of the direct airflow interference. At the same time, the polytetrafluoroethylene membrane reduces frictional resistance and avoids wear of the rotating wheel. For the small gap between the elastic strips 34 and the molecular sieve rotating disk 2, the negative pressure generated by the suction pump 36 inside the negative pressure sealing groove will actively adsorb the cross-flowing air in the gap. The air enters from the inside of the notch 35, gathers inside the elastic strips 34, and is discharged to the outside. When the external airflow blows onto the damp surface of the molecular sieve rotating disk 2, it first passes through the heating device 4. The heated airflow then flows onto the surface of the molecular sieve rotating disk 2, drying the damp surface and participating in the subsequent dehumidification process. After the air blown from the surface of the molecular sieve rotating disk 2 passes through the molecular sieve rotating disk 2, it is guided by the air-guiding device 5 to the top of the ozone generator 6. The ozone generator 6 discharges ozone to the outlet of the air-guiding device 5. The ozone mixed with air is discharged to the outside, and the ozone is used to disinfect the external space.
