Description

Technical Field

[0001] The present application relates to the technical field of sterile cabins, and in particular to a circulating energy-saving dehumidification control device in a sterile transfer cabin. Background Art

[0002] In the process of hydrogen peroxide sterilization, existing equipment requires a high-concentration 30%-35% hydrogen peroxide solution to continuously fill the sterilization cavity through flash vaporization to maintain a certain concentration of hydrogen peroxide gas in the cavity. Continuous vaporization of hydrogen peroxide will cause the humidity of the cavity to quickly become saturated, accompanied by condensation, causing corrosion to the cavity and the sterilized items in the cavity. High-concentration hydrogen peroxide is a highly corrosive liquid and cannot be directly contacted by the skin, which can easily cause damage. The existing treatment method is to replace the air in the cavity with dry compressed air before hydrogen peroxide vaporizes and fills the cavity, reducing the humidity of the cavity to below the set value (generally below 30% RH). This step is the dehumidification stage in the sterilization automation program, and generally takes 5-10 minutes.

[0003] The entire automated sterilization process is divided into four stages. The second step is the pre-sterilization stage. When the first stage of dehumidification of the equipment is completed, the program automatically enters the second stage. At this time, the hydrogen peroxide liquid begins to vaporize and emits hydrogen peroxide gas into the sterilization chamber. Until the hydrogen peroxide concentration detection probe in the chamber detects that the chamber concentration reaches the set value, however, during the process of increasing the hydrogen peroxide concentration in the chamber, the accompanying defect is that the humidity in the chamber also increases. In order to prevent condensation in the internal chamber, dry compressed air needs to be filled in to replace the gas in the chamber and reduce the humidity in the chamber.

[0004] The duration of this process is 15-30 minutes, depending on the nature of the process. When the concentration in the cavity reaches the set value, the program automatically enters the third step, the sterilization stage. This stage is to maintain the hydrogen peroxide concentration above the set value. Therefore, hydrogen peroxide still needs to be continuously generated in the cavity during this stage, accompanied by the phenomenon of rising humidity. When the humidity rises to a certain value, dry compressed air is also used to replace the gas in the cavity to reduce the humidity of the cavity. The process time is set to be no less than 30 minutes. When the sterilization time reaches the set value, the program automatically enters the fourth step, the residual discharge stage. In this stage, hydrogen peroxide vaporization ends, and hydrogen peroxide gas is no longer injected into the cavity. At the same time, the air supply and exhaust valve and the air supply and exhaust fan are started to discharge the hydrogen peroxide gas in the cavity through air supply and exhaust until the hydrogen peroxide concentration in the cavity is lower than the set value (below 1ppm), and finally the sterilization program ends.

[0005] The main disadvantages of the existing technology are that a large amount of compressed air is used during the entire equipment operation stage, which is not economical. At the same time, during the dehumidification process of the compressed air, in order to ensure the stability of the pressure in the sealed cavity, the pressure relief valve needs to be opened to exhaust air. The exhaust process will also carry hydrogen peroxide gas out of the cavity. Summary of the invention

[0032] The following describes an energy-saving and dehumidification control device for a sterile transfer cabin according to an embodiment of the present application in conjunction with the accompanying drawings.

[0033] A sterile transfer cabin internal circulation energy-saving dehumidification control device provided in an embodiment of the present application can be applied to the technical field of sterile cabins.

By adding a heater, the desiccant can be dried in the residual discharge stage and can be recycled without frequent replacement or maintenance of the desiccant.

[0034] like Figure 1-9 As shown, an energy-saving and dehumidification control device for an internal circulation in a sterile transfer cabin according to an embodiment of the present application includes a transfer cabin 10, an air supply filter assembly 20, an air inlet fan 30, a ventilation duct 40, an air supply butterfly valve 50, an internal circulation control assembly 60, an exhaust filter assembly 70, a fixed plate 80 and an air outlet fan 90.

[0035] Among them, the air supply filter assembly 20 is arranged on the top wall of the transfer cabin 10, the air inlet fan 30 is arranged on the air supply filter assembly 20, one end of the ventilation pipe 40 is arranged at the air inlet port of the air inlet fan 30, and the air supply butterfly valve 50 is arranged at the connection between the air inlet fan 30 and the air supply filter assembly 20.

[0036] It should be noted that the air intake fan 30 is operated by connecting a control switch and a power source, and draws in external air through the ventilation pipe 40 and delivers it to the air supply filter assembly 20. The air is filtered through the air supply filter assembly 20, and the filtered air is delivered to the transfer cabin 10.

[0037] The internal circulation control component 60 is arranged on the transfer cabin 10, and the internal circulation control component 60 includes an internal circulation supply air butterfly valve 601, a flash evaporation module 602, an internal circulation fan 603, a dehumidification butterfly valve 604, an internal circulation return air butterfly valve 605, a heating and drying mechanism 606, a pressure relief butterfly valve 607 and an exhaust butterfly valve 608.

[0038] Among them, one end of the internal circulation air supply butterfly valve 601 is connected to the transfer cabin 10 through the ventilation pipe 40, one end of the flash module 602 is connected to the other end of the internal circulation air supply butterfly valve 601 through the ventilation pipe 40, and one end of the internal circulation fan 603 is connected to the other end of the flash module 602 through the ventilation pipe 40. One end of the dehumidification butterfly valve 604 is connected to the other end of the internal circulation fan 603 through the ventilation pipe 40, one end of the internal circulation return air butterfly valve 605 is connected to the other end of the dehumidification butterfly valve 604 through the ventilation pipe 40, and the other end of the internal circulation return air butterfly valve 605 is connected to the transfer cabin 10. The two ends of the heating and drying mechanism 606 are respectively connected to the internal circulation fan 603 and the dehumidification butterfly valve 604 through the ventilation pipe 40, and the pressure relief butterfly valve 607 and the exhaust butterfly valve 608 are respectively connected to the transfer cabin 10 through the ventilation pipe 40.

[0039] It should be noted that the hydrogen peroxide solution is vaporized by the flash module 602, and the hydrogen peroxide gas is delivered to the transfer cabin 10 through the internal circulation air supply butterfly valve 601. The internal circulation fan 603 delivers the heated air to the transfer cabin 10 again. The humid gas in the transfer cabin 10 is dried and delivered to the heating and drying mechanism 606 through the internal circulation return air butterfly valve 605 and the dehumidification butterfly valve 604.

[0040] It should be noted that the sterilized gas in the transfer cabin 10 will be depressurized through the pressure relief butterfly valve 607 and the exhaust butterfly valve 608, and the air will be discharged through the ventilation pipe 40. When discharged, it will be efficiently filtered through the exhaust filter assembly 70 to discharge sterile and clean gas.

[0041] The exhaust filter assembly 70 is arranged on the internal circulation control assembly 60 , the fixed plate 80 is arranged on the exhaust filter assembly 70 , the air outlet fan 90 is arranged on the exhaust filter assembly 70 , and the ventilation pipe 40 is arranged at the air outlet port of the air outlet fan 90 .

[0042] It should be noted that the exhaust filter assembly 70 effectively filters the gas being transported, and then exhausts the air through the exhaust fan 90.

[0043] Specifically, the steps of energy-saving dehumidification in the sterile transfer cabin are as follows: hydrogen peroxide solution is placed in the flash module 602, the hydrogen peroxide solution is vaporized by the flash module 602 and transported to the transfer cabin 10 through the internal circulation air supply butterfly valve 601. External air is sucked in and transported to the air supply filter assembly 20 through the air inlet fan 30 and the ventilation pipe 40, and the external air is filtered and transported to the transfer cabin 10 through the air supply filter assembly 20. The air and hydrogen peroxide gas are replaced in the transfer cabin 10, and the humidity of the cavity is reduced to below the set value (generally below 30% RH). The replaced gas is transported to the internal circulation control assembly 60 through the ventilation duct 40. The humid gas in the transfer cabin 10 passes through the internal circulation return air butterfly valve 605 and the dehumidification butterfly valve 604 to dry the humid gas and transport it to the heating and drying mechanism 606. Desiccant is added to the heating and drying mechanism 606 to ensure the dryness of the air before transporting it to the transfer cabin 10. The gas exhaust is transported through the pressure relief butterfly valve 607 and the exhaust butterfly valve 608, and then the gas in transit is effectively filtered through the exhaust filter assembly 70, and then the air is discharged through the exhaust fan 90.

[0044] In one embodiment of the present application, Figure 2 As shown, the air supply filter assembly 20 includes an outer frame 201 , a first filter component 202 , a screening mechanism 203 , a second filter component 204 and a third filter component 205 .

[0045] The first filter component 202 is detachably disposed in the outer frame 201 , the screening mechanism 203 is detachably disposed in the outer frame 201 , the second filter component 204 is detachably disposed in the outer frame 201 , and the third filter component 205 is detachably disposed in the outer frame 201 .

[0050] It should be noted that the collection trough 2024 in the fixed frame 2021 is opened in the middle position, and the size and depth of the collection trough 2024 are set according to the actual situation. For example, when the screening mechanism 203 is large, the size and depth of the collection trough 2024 are large, and vice versa. The stoppers 2023 are respectively set at the four angles of the inner wall of the fixed frame 2021, and the filter screen is supported and installed in the fixed frame 2021 through the stoppers 2023.

[0051] In one embodiment of the present application, Figure 3 and Figure 4 As shown, the support mechanism 2022 includes a movable shaft 20221 , a collar 20222 , a positioning shaft 20223 and a support member 20224 .

[0052] The movable shaft 20221 is movably arranged in the fixed frame 2021, the collars 20222 are multiple groups, and the multiple groups of collars 20222 are respectively arranged on the movable shaft 20221.

The supporting members 20224 are multiple groups, and the multiple groups of supporting members 20224 are correspondingly arranged on the positioning shafts 20223.

[0053] It should be noted that the movable shaft 20221 moves in the fixed frame 2021, and then the movable shaft 20221 synchronously drives the sleeve ring 20222 to move. At this time, the positioning shaft 20223 is limited, and the support member 20224 is flipped to support the upper component.

[0054] In one embodiment of the present application, Figure 5 As shown, the support member 20224 includes a movable sleeve 202241, a lower fixing frame 202242 and a top rod 202243.

The heating component 6063 is arranged in the inner shell 6062, and the drying mechanism 6064 is arranged in the outer shell 6061, and the drying mechanism 6064 is arranged above the heating component 6063.

[0059] It should be noted that the inner housing 6062 is installed in the outer housing 6061, and the heating component 6063 is operated by connecting the control switch and the power supply. When the heating component 6063 is in operation, the desiccant added in the drying mechanism 6064 is heated. The air passes through the desiccant to remove moisture from the air, ensuring the dryness of the air and then is sent to the transfer cabin 10 to reduce the humidity in the transfer cabin 10.

[0060] In one embodiment of the present application, Figure 7 As shown, the drying mechanism 6064 includes a storage shell 60641, a driving member 60642, a discharge port 60643, a sealing cover 60644, a feed pipe 60645, a screening frame 60646 and a screen 60647.

The conveying component 606424 drives the fixed shaft 606423 to rotate, and then drives the sealing cover 60644 to rotate, and at the same time drives the swing rod 606425 to swing, so as to push away the desiccant blocking the discharge port 60643 to prevent blockage.

[0066] In one embodiment of the present application, Fig. 9 As shown, the screening mechanism 203 includes a frame 2031 , a rotating shaft 2032 , a screening net 2033 , a base frame 2034 and a scraper 2035 .

[0067] The grid frame 2031 is detachably disposed in the outer frame 201, the rotating shaft 2032 is rotatably disposed in the grid frame 2031, and the screening net 2033 is disposed on the rotating shaft 2032.

The output end of the motor is connected to the rotating shaft 2032 through a reducer. When the rotating shaft 2032 rotates, the sieve net 2033 is driven to rotate, and then when the gas passes through, the impurities in the gas will be filtered through the sieve net 2033. And the impurities are scraped off by the scraper 2035 and fall into the collection tank 2024.

[0069] Specifically, the control steps of the cyclic energy-saving dehumidification in the sterile transfer cabin are as follows: hydrogen peroxide solution is added into the flash module 602, and the hydrogen peroxide solution is vaporized into gas by the flash module 602, and the hydrogen peroxide gas enters the transfer cabin 10, and then the interior of the transfer cabin 10 is sterilized by hydrogen peroxide. The external air is transported to the air supply filter assembly 20 through the air inlet fan 30 and the ventilation pipe 40, and the sieving mechanism 203 in the air supply filter assembly 20 filters the impurities in the air, and the air passes through the sieving net 2033 and the impurities are retained on the sieving net 2033. When the sieving net 2033 rotates, the scraper 2035 abuts against the sieving net 2033, and the scraper 2035 scrapes the impurities on the sieving net 2033 and drops them into the collecting trough 2024. Then, the excess impurities in the air are filtered through the first filter component 202, the second filter component 204 and the third filter component 205.

[0070] When the filter component and the screening mechanism 203 are installed in the inner cavity of the outer frame 201, the filter component and the screening mechanism 203 are supported by the support mechanism 2022. When installing, the third filter component 205 at the bottom is first installed in the outer frame 201. Then the movable shaft 20221 is pushed, and the movable shaft 20221 is pushed to move in the fixed frame 2021. When the movable shaft 20221 moves, it synchronously drives the collar 20222 to move. At this time, the positioning shaft 20223 is limited, and the support member 20224 is turned over to drive the top rod 202243 to press against the bottom wall of the second filter component 204. In this way, the second filter component 204, the first filter component 202 and the screening mechanism 203 are installed in the outer frame 201 in sequence.

[0071] The steps of drying the gas by the heating and drying mechanism 606 are as follows: the inner shell 6062 is installed in the outer shell 6061, the desiccant is added into the storage shell 60641 through the feeding pipe 60645, and then the driving member 60642 is operated. When the driving member 606422 is operated, the conveying member 606424 is driven to rotate, the conveying member 606424 drives the fixed shaft 606423 to rotate, and the fixed shaft 606423 drives the blocking cover 60644 to rotate, thereby opening the discharge port 60643, and the desiccant slides from the discharge port 60643 into the screen 60647. When the fixed shaft 606423 rotates, the swing rod 606425 is synchronously driven to flip, and when the swing rod 606425 rotates, the desiccant blocking the discharge port 60643 is pushed away to prevent blockage. At this time, the heating component 6063 is operated to heat the desiccant on the screen 60647, and the dry air enters the transfer cabin 10 to dehumidify the inner cavity of the transfer cabin 10. The heating component 6063 dries the desiccant, and then the desiccant is recycled.

[0072] The discharge step is as follows: after the hydrogen peroxide is consumed, the input of hydrogen peroxide to the flash module 602 is stopped. Then, the exhaust butterfly valve 608 and the air outlet fan 90 are operated, and the air outlet fan 90 extracts the gas in the transfer chamber 10, and then the exhaust gas is filtered again through the exhaust filter assembly 70, and finally discharged through the ventilation pipe 40.

[0073] In summary, a circulating energy-saving dehumidification control device in a sterile transfer cabin according to an embodiment of the present application reduces the use of compressed air and reduces the loss of hydrogen peroxide gas by adding a desiccant. Adding a heater can dry the desiccant during the residual discharge stage, and the desiccant can be recycled without frequent replacement or maintenance of the desiccant.

Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present application.
