Description

Technical Field

[0001] The present invention relates to the technical field of air compressors, specifically to a sterilization device, and more specifically to a sterilization method for an energy-saving gas compressor. Background Art

[0002] An energy-saving gas compressor is a highly efficient and environmentally friendly gas compression device. A gas compressor usually has an input end and an output end, and air enters the gas compressor through the input end. Traditional gas compressors do not have a sterilization and disinfection device, and usually sterilize and disinfect the high-speed air flow output by the gas compressor.

[0003] The patent document with the publication number CN213574544U discloses a pre-sterilization and disinfection device for a breathing air compressor. It forms a low pressure inside the housing through a vacuum compressor. The low pressure inside the housing generates suction at the dust filter connected to it, and external air enters the housing through the dust filter. The dust filter filters the air, and the air enters the housing and flows along the diameter direction of the housing. The ultraviolet lamp irradiates and sterilizes the air inside the housing, and the sterilized air finally enters the air compressor.

[0004] Although the above patent realizes the sterilization of air before it enters the air compressor, when the air flows inside the housing, the air is in a stable flow state, and the air velocity will be stratified. The air flowing along the surface of the ultraviolet lamp will have a relatively slow velocity due to the obstruction of the ultraviolet lamp, and the air flowing along this path will receive a longer irradiation sterilization time. While the air slightly away from the surface of the ultraviolet lamp has a relatively fast velocity, and this part of the air will pass through the irradiation range of the ultraviolet lamp faster and receive a shorter irradiation sterilization time, resulting in different sterilization effects of the air flowing in each layer inside the housing.

[0017] S2. The gas flows along the sterilization tube towards the gas compressor, and the first translation mechanism adjusts several first ultraviolet lamps to translate simultaneously, changing the distance between the first ultraviolet lamp and the central axis of the sterilization tube.

[0018] S3. The second translation mechanism adjusts the simultaneous translation of several second ultraviolet lamps, and the translation direction of the second ultraviolet lamps is opposite to that of the first ultraviolet lamps;

[0019] S4. The gas enters the gas compressor after being irradiated and sterilized by several first ultraviolet lamps and several second ultraviolet lamps.

[0020] The beneficial effects of the present invention compared with the prior art are as follows:

[0021] 1. The present invention is provided with a first ultraviolet lamp, a first translation mechanism and an opening and closing maintenance mechanism. The annular array setting of the first ultraviolet lamp enables the gas to be irradiated omnidirectionally when flowing in the sterilization tube, improving the sterilization efficiency and effect, ensuring the comprehensive sterilization of the gas. The design of the opening and closing maintenance mechanism enables the sterilization tube to be conveniently opened when the first ultraviolet lamp fails, and the sterilization mechanism can be taken out and maintained, improving the reliability and maintainability of the system. The first translation mechanism enables the first ultraviolet lamp to be adjusted translationally according to the flow rate of the gas, slowing down the passing speed of the gas with too fast flow rate and accelerating the flow of the gas with slower flow rate, so as to control the flow time of the gas in the sterilization tube and avoid the problem of uneven sterilization caused by uneven flow rate.

Detailed implementation manners

[0039] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0040] Refer to Figures 1 to 14As shown in the figure: A sterilization device includes a sterilization channel 1, a sterilization mechanism 2, and an opening / closing and maintenance mechanism 3; the sterilization channel 1 includes a sterilization tube 11 and two end covers 12. Both ends of the sterilization tube 11 are provided with ports 1111, and the axis of the port 1111 passes through the central axis of the sterilization tube 11. The two ports 1111 are respectively externally connected to a dust filter and a gas compressor, and the two end covers 12 are respectively arranged at both ends of the sterilization tube 11; the sterilization mechanism 2 is arranged inside the sterilization tube 11. The sterilization mechanism 2 includes a plurality of first ultraviolet lamps 21 and a first translation mechanism 22. The plurality of first ultraviolet lamps 21 are arranged in a circular array with respect to the central axis of the sterilization tube 11. The first translation mechanism 22 includes a first double-headed screw 221 and two first moving blocks 222. Both ends of the first double-headed screw 221 are respectively connected to the two end covers 12, and the axis of the first double-headed screw 221 is collinear with the central axis of the sterilization tube 11. The two first moving blocks 222 are respectively arranged at both ends of the first double-headed screw 221, and a plurality of first driving plates 223 are arranged in a circular array on each first moving block 222. The plurality of first driving plates 223 respectively correspond to the plurality of first ultraviolet lamps 21. Both ends of the first driving plate 223 are respectively pivotally connected to the end of the sterilization tube 11 and the first moving block 222. The first translation mechanism 22 further includes a first rotation driver 224. The first rotation driver 224 is arranged outside the sterilization tube 11, and the first rotation driver 224 is used to drive the first double-headed screw 221 to rotate; there are two opening / closing and maintenance mechanisms 3, and the two opening / closing and maintenance mechanisms 3 are respectively arranged at both ends of the sterilization tube 11. The opening / closing and maintenance mechanism 3 is used to open the sterilization tube 11 to maintain the sterilization mechanism 2.

[0041] The gas compressor starts, generating suction inside the sterilization tube 11, causing the port 1111 connected to the dust filter to form a negative pressure, thereby attracting external air to enter. The air first passes through the dust filter, and the impurities therein are effectively adsorbed to ensure that the gas entering the sterilization tube 11 is relatively pure. The pretreated gas flows from one port 1111 to another port 1111 inside the sterilization tube 11. During the flow process, several first ultraviolet lamps 21 are arranged in a circular array inside the sterilization tube 11 to irradiate and sterilize the gas in all directions. When a first ultraviolet lamp 21 fails, the two opening and closing maintenance mechanisms 3 open the sterilization tube 11, and the sterilization mechanism 2 is taken out for maintenance. When the gas flows in the sterilization tube 11, the gas flowing along the first ultraviolet lamp 21 has a slower flow rate due to the obstruction of the first ultraviolet lamp 21, so that this part of the gas can obtain a longer irradiation and sterilization time, while the gas at a certain distance from the first ultraviolet lamp 21 has a faster flow rate and this part of the gas obtains a shorter irradiation and sterilization time. Therefore, the first translation mechanism 22 is provided. The first rotation driver 224 starts, driving the first double-headed screw 221 to rotate, so that the two first moving blocks 222 move on the screw, and the first ultraviolet lamp 21 is driven to move away from or close to the central axis of the sterilization tube 11 through the first driving plate 223. The translation adjustment of the first ultraviolet lamp 21 can ensure that the first ultraviolet lamp 21 contacts the gas with different flow rates, which not only slows down the passing speed of the gas with too fast flow rate, but also speeds up the flow of the gas with slower flow rate, thereby realizing the control of the flow time of the gas in the sterilization tube 11 and avoiding the problem of uneven sterilization caused by uneven flow rate.

[0042] Refer to Figure 4 , Figure 5 and Figure 6 As shown: The sterilization mechanism 2 further includes several first guiding and connecting structures 23. Every two first guiding and connecting structures 23 are a group and are respectively arranged at both ends of the first ultraviolet lamp 21. The first guiding and connecting structure 23 includes a first guiding structure 231 and a second moving block 232; the first guiding structure 231 is arranged on the end cover plate 12. The first guiding structure 231 includes a first guiding rod 2311, and the guiding direction of the first guiding rod 2311 is parallel to a diameter of the end cover plate 12. The first guiding structure 231 further includes a first U-shaped frame 2312 and two first springs 2313. The first U-shaped frame 2312 is fixed on the end cover plate 12, and both ends of the first guiding rod 2311 are connected to both ends of the first U-shaped frame 2312. Both first springs 2313 are sleeved on the first guiding rod; the second moving block 232 is connected to the end of the first ultraviolet lamp 21 and the first driving plate 223, and the second moving block 232 is slidably arranged on the first guiding rod 2311.

[0043] During the translation of the first ultraviolet lamp 21, if the two ends of the first ultraviolet lamp 21 move out of sync, it will cause the first ultraviolet lamp 21 to tilt or even break. Therefore, the first guiding structure 231 and the second moving block 232 are provided. The two second moving blocks 232 are connected to the two ends of the first ultraviolet lamp 21. When the first translation mechanism 22 drives the two second moving blocks 232 to move along the two first guiding rods 2311 respectively, the first spring 2313 provides a buffering effect and a thrust effect for the second moving block 232. The two second moving blocks 232 maintain synchronous movement under the action of the two first driving plates 223, preventing the first ultraviolet lamp 21 from tilting or the tilting angle from increasing during translation, thereby ensuring the synchronism and accuracy of the two ends of the first ultraviolet lamp 21 during translation and avoiding the risk of tilting or breaking caused by the asynchronous movement of the two ends.

[0044] Refer to Figure 6 and Figure 7 As shown: The first guiding and connecting structure 23 further includes a clamping structure 233. The clamping structure 233 is arranged on the second moving block 232. The clamping structure 233 includes a U-shaped cover 2331 and two arc-shaped clamping plates 2332; The U-shaped cover 2331 is fixedly connected to the second moving block 232, and the opening of the U-shaped cover 2331 faces away from the center of the end cover plate 12; The two arc-shaped clamping plates 2332 are symmetrically arranged inside the U-shaped cover 2331. Guide posts 2333 are arranged on the opposite sides of the two arc-shaped clamping plates 2332. One end of the guide post 2333 extends out of the U-shaped cover 2331, and a second spring 2334 is also sleeved on the guide post 2333. The two ends of the second spring 2334 are respectively in contact with the arc-shaped clamping plate 2332 and the U-shaped cover 2331.

[0045] The first ultraviolet lamp 21 needs to move along with the two second moving blocks 232. Therefore, the first ultraviolet lamp 21 needs to be fixedly connected to the two second moving blocks 232. However, the first ultraviolet lamp 21 is relatively long, making it inconvenient for the staff to fixedly connect the first ultraviolet lamp 21 to the two second moving blocks 232. Thus, a clamping structure 233 is provided. When installing the relatively long first ultraviolet lamp 21, the staff only needs to align the two ends of the first ultraviolet lamp 21 with the two clamping structures 233 respectively and gently press the first ultraviolet lamp 21. The end of the first ultraviolet lamp 21 will contact the two arc-shaped clamping plates 2332 and push the two arc-shaped clamping plates 2332 away from each other. The second springs 2334 on the guide posts 2333 corresponding to the two arc-shaped clamping plates 2332 will be gradually compressed, storing a large amount of elastic potential energy. When the end of the first ultraviolet lamp 21 completely enters between the arc-shaped clamping plates 2332, the second springs 2334 will quickly release the previously stored elastic potential energy, pushing the arc-shaped clamping plates 2332 back to their original positions rapidly and clamping tightly from both sides of the first ultraviolet lamp 21. In this way, the first ultraviolet lamp 21 can be stably connected to the two second moving blocks 232, thus simplifying the installation process of the first ultraviolet lamp 21 without complex operations or additional tools and improving the installation efficiency of the first ultraviolet lamp 21.

[0046] Refer to Figure 4 , Figure 5 and Figure 8 As shown in

[0047] When the first ultraviolet lamp 21 is far from the central axis of the sterilization tube 11, the first ultraviolet lamp 21 is farther from the gas near the central axis of the sterilization tube 11, and the sterilization effect of the first ultraviolet lamp 21 on the gas at this place is poor. Therefore, a number of second ultraviolet lamps 24, second translation mechanisms 25 and second guiding connection structures 26 are provided. In the initial state, a number of second ultraviolet lamps 24 are arranged around the central axis of the sterilization tube 11 to form an annular array. At the same time, the second ultraviolet lamps 24 and the original first ultraviolet lamp 21 are arranged in an interleaved manner, ensuring the full coverage of the sterilization light and reducing the sterilization blind area. When the first ultraviolet lamp 21 is driven by the first translation mechanism 22 to move away from the central axis of the sterilization tube 11, in order to ensure the sterilization effect, the second translation mechanism 25 will be activated simultaneously. The second double-headed screw 251 rotates, driving the two third moving blocks 252 to approach each other, and then pushing the second ultraviolet lamp 24 to move towards the central axis of the sterilization tube 11 through the second driving plate 253, so that the gas farther from the first ultraviolet lamp 21 can be irradiated and supplemented by the second ultraviolet lamp 24, ensuring the comprehensiveness and uniformity of the sterilization effect. At the same time, the moving directions of the first ultraviolet lamp 21 and the second ultraviolet lamp 24 always remain opposite. When the first ultraviolet lamp 21 translates in one direction, the second ultraviolet lamp 24 will change the translation direction simultaneously, thus ensuring the full and efficient sterilization of the gas in the sterilization tube 11 and reducing the sterilization blind area.

[0048] Refer to Figure 4 、 Figure 5 and Figure 9 As shown: The sterilization mechanism 2 further includes a synchronous rotation connection structure 27. The synchronous rotation connection structure 27 is arranged in the middle of the second double-headed screw 251. The synchronous rotation connection structure 27 includes a connection sleeve 271 and a plug-in block 272. The connection sleeve 271 is sleeved in the middle of the second double-headed screw 251. The plug-in block 272 passes through the first double-headed screw 221 and the second double-headed screw 251, and both ends of the plug-in block 272 are fixedly connected to both ends of the connection sleeve 271. And the spiral directions of the two threads on the same side of the first double-headed screw 221 and the second double-headed screw 251 are opposite.

[0049] Both the first double-headed screw rod 221 and the second double-headed screw rod 251 need to be driven by a rotary drive device. By setting up a synchronous rotation connection structure 27, the insertion block 272 fixes the first double-headed screw rod 221 and the second double-headed screw rod 251. When the first rotary driver 224 drives the first double-headed screw rod 221 to rotate, the first double-headed screw rod 221 drives the second double-headed screw rod 251 to rotate through the insertion block 272. The rotation direction of the second double-headed screw rod 251 is the same as that of the first double-headed screw rod 221. The spiral directions of the two threads on the same side of the first double-headed screw rod 221 and the second double-headed screw rod 251 are set to be opposite, forming a partial double-headed screw rod. During the synchronous rotation of the first double-headed screw rod 221 and the second double-headed screw rod 251, the second moving block 232 and the third moving block 252 approach or move away from each other, making the motion states of the first ultraviolet lamp 21 and the second ultraviolet lamp 24 opposite, so as to realize the synchronous operation of the first translation mechanism 22 and the second translation mechanism 25.

[0050] Refer to Figure 4 、 Figure 5 and Figure 10 As shown: Two limiting structures 28 are respectively arranged on the two end covers 12. The limiting structure 28 is used to limit the moving paths of the first moving block 222 and the third moving block 252. The limiting structure 28 includes a fixed ring 281 and a plurality of guiding cross bars 282. The fixed ring 281 is fixed on the end cover 12. The plurality of guiding cross bars 282 are annularly arranged around the first double-headed screw rod 221. One end of the guiding cross bar 282 is connected to the fixed ring 281, and the other end of the guiding cross bar 282 passes through the first moving block 222 and the third moving block 252, and the guiding cross bar 282 is slidably connected to the first moving block 222 and the third moving block 252.

[0051] The functions of the first guiding connection structure 23 and the second guiding connection structure 26 prevent the first moving block 222 and the third moving block 252 from rotating, so that the first double-headed screw rod 221 and the second double-headed screw rod 251 can drive the first moving block 222 and the third moving block 252 to only move linearly. However, the first driving plate 223 and the second driving plate 253 will be subjected to torsional forces. By setting up the limiting structure 28, the guiding cross bar 282 passes through the first moving block 222 and the third moving block 252. The plurality of guiding cross bars 282 can absorb the rotational acting forces received by the first moving block 222 and the third moving block 252, and the first moving block 222 and the third moving block 252 always keep in contact with the guiding cross bar 282 during the moving process, avoiding the rotational acting forces received by the first moving block 222 and the third moving block 252 from being transmitted to the first driving plate 223 and the second driving plate 253, thereby effectively absorbing the rotational acting forces and avoiding the adverse effects on the first driving plate 223 and the second driving plate 253, and prolonging the service life of the equipment.

[0052] Refer toFigure 2 , Figure 11 and Figure 12 As shown in Figure 2 , Figure 11 and Figure 12 , the sterilization tube 11 includes a first arc-shaped plate 111 and two second arc-shaped plates 112. The first arc-shaped plate 111 and the two second arc-shaped plates 112 enclose a complete cylinder, and the two second arc-shaped plates 112 are located at the lower end of the first arc-shaped plate 111. Connecting shafts 1121 are provided on both of the two second arc-shaped plates 112. The opening and closing maintenance mechanism 3 includes a frame 31, a fourth moving block 32 and a bidirectional driving structure 33. The frame 31 is arranged at one end of the sterilization channel 1. There are two third moving blocks 252, and the two fourth moving blocks 32 are respectively connected to the connecting shafts 1121 on the two second arc-shaped plates 112. The bidirectional driving structure 33 is horizontally arranged at the upper end of the frame 31, and the bidirectional driving structure 33 is used to drive the two fourth moving blocks 32 to approach or move away from each other on the horizontal plane. The bidirectional driving structure 33 includes a second U-shaped frame 331, a third double-headed screw 332, a second rotary driver 333 and a bevel gear transmission group 334. The second U-shaped frame 331 is fixed on the frame 31. The two ends of the third double-headed screw 332 are respectively connected to the two ends of the second U-shaped frame 331. The second rotary driver 333 is arranged in the middle of the second U-shaped frame 331. The bevel gear transmission group 334 is used to transmit the power of the second rotary driver 333 to the third double-headed screw 332.

[0053] The overall length of the sterilization mechanism 2 is relatively long. If the sterilization mechanism 2 is directly pulled out along the diameter direction of the sterilization tube 11, enough space needs to be reserved at one end of the sterilization tube 11, which increases the floor space of the device. Therefore, the sterilization tube 11 is set as the first arc-shaped plate 111 and the two second arc-shaped plates 112. When the sterilization mechanism 2 needs to be maintained, the two opening and closing maintenance mechanisms 3 will be started simultaneously. The second rotary driver 333 starts to operate, and the power is transmitted to the third double-headed screw 332 through the bevel gear transmission group 334. As the third double-headed screw 332 rotates, the two fourth moving blocks 32 are driven to move away from each other. The two fourth moving blocks 32 are also connected to the two second arc-shaped plates 112 through the connecting shafts 1121. Therefore, when they move away from each other, they will drive the two second arc-shaped plates 112 to separate from each other, exposing the sterilization mechanism 2, which is convenient for the operator to maintain, thus greatly saving the space required for the use of the device and making the overall structure more compact and occupying less floor space.

[0054] Refer to Figure 11 and Figure 13As shown: The opening and closing maintenance mechanism 3 further includes a second guiding structure 34 and a linkage assembly 35; The second guiding structure 34 is arranged on the frame 31, and the guiding direction of the second guiding structure 34 is perpendicular to the moving direction of the bidirectional driving structure 33 driving the fourth moving block 32. The second guiding structure 34 includes a fifth moving block 341, and the fifth moving block 341 is connected to the sterilization channel 1. The fifth moving block 341 moves along the guiding direction of the second guiding structure 34. The second guiding structure 34 further includes a rectangular frame 342, two second guiding rods 343, a first connecting block 344 and a second connecting block 345. One end of the rectangular frame 342 is connected to the frame 31. The two second guiding rods 343 are arranged in parallel inside the rectangular frame 342. The two ends of the fifth moving block 341 are respectively slidably connected to the two second guiding rods 343. The first connecting block 344 connects the fifth moving block 341 and the end cover plate 12. The second connecting block 345 connects the first arc-shaped plate 111 and the rectangular frame 342; There are two linkage assemblies 35, and the two linkage assemblies 35 are respectively arranged at the two ends of the fifth moving block 341. The two ends of the linkage assembly 35 are respectively connected to the fifth moving block 341 and the connecting shaft 1121.

[0055] Although the two second arc-shaped plates 112 are separated from each other and the sterilization mechanism 2 is exposed, the two second arc-shaped plates 112 are still located on both sides of the sterilization mechanism 2. By arranging the second guiding structure 34 and the two linkage assemblies 35, during the process of the two fourth moving blocks 32 driving the two second arc-shaped plates 112 to move away from each other, the two connecting shafts 1121 simultaneously apply a downward acting force on the fifth moving block 341 through the two linkage assemblies 35, so that the fifth moving block 341 moves downward along the second guiding rod 343. The fifth moving block 341 drives the entire sterilization mechanism 2 to move downward through the end cover plate 12, thereby moving the sterilization mechanism 2 out of the range opposite to the two second arc-shaped plates 112.

[0056] Refer to Figure 13 and Figure 14 As shown: The linkage assembly 35 includes a first telescopic arm 351, a second telescopic arm 352 and a third spring 353; One end of the first telescopic arm 351 is axially connected to the end of the connecting shaft 1121; One end of the second telescopic arm 352 is axially connected to the fourth moving block 32. The second telescopic arm 352 and the first telescopic arm 351 are coaxially arranged, and the second telescopic arm 352 and the first telescopic arm 351 are slidably connected to each other; The third spring 353 is sleeved on the first telescopic arm 351 and the second telescopic arm 352, and the two ends of the third spring 353 are respectively abutted against the end of the first telescopic arm 351 and the end of the second telescopic arm 352.

[0057] When the opening and closing maintenance mechanism 3 is activated and drives the two second arc plates 112 to move towards each other, the two linkage components 35 are like bridges, leading the entire sterilization mechanism 2 to move steadily towards the first arc plate 111. When the end covers 12 at both ends of the sterilization mechanism 2 gently abut against the two ends of the first arc plate 111, the two second arc plates 112 also just abut against each other, forming a preliminary closed structure. To ensure the tight connection between the first arc plate 111 and the two second arc plates 112, it is necessary to continue applying a force towards each other to the two second arc plates 112. This force is transmitted to the sterilization mechanism 2 through the linkage component 35. Then, under the push of this force, the end cover 12 will exert an upward force on the first arc plate 111, further enhancing the tightness of the connection. During this process, as the two second arc plates 112 continuously approach, a relative displacement occurs between the first telescopic arm 351 and the second telescopic arm 352, and the total length of the first telescopic arm 351 and the second telescopic arm 352 shortens, creating a space for the two second arc plates 112 to approach each other, thereby enhancing the tightness of the connection between the first arc plate 111 and the two second arc plates 112.
