Description

Technical Field

[0001] The invention relates to the technical field of disinfection devices, in particular to a sterilization device used for contact lens packaging. Background Art

[0002] The ultraviolet disinfection equipment for contact lens packaging is a professional disinfection device designed specifically for contact lens production lines. It is intended to sterilize packaging materials, product surfaces during the packaging process, and production equipment to ensure that contact lens products meet medical and health standards after packaging.

[0003] In ultraviolet sterilization equipment, the surface of the product transported by the conveyor belt is only exposed to ultraviolet radiation on one side of the conveyor belt, and the other side of the product contacted by the conveyor belt cannot directly receive the sterilization effect of ultraviolet rays. The core principle of ultraviolet sterilization is to destroy the DNA or RNA structure of microorganisms through high-energy photon radiation in the ultraviolet C band (UV-C, wavelength 200-280nm), making them lose their biological activity. However, ultraviolet rays have weak penetration. For solid materials or opaque objects, their sterilization effect is limited to the surface or near the surface that can be directly illuminated by light. Therefore, the shadow area caused by shading can hardly complete effective sterilization. The reason for this phenomenon can be attributed to the physical properties of ultraviolet rays themselves. The energy of UV-C photons makes it easy for them to be absorbed by molecules on the surface of the material, causing their light to decay rapidly or even completely lose its sterilization effect when it encounters obstacles. Therefore, although the equipment may be designed with high-intensity ultraviolet lamps or reflectors, its sterilization effect depends on the radiation light path and contact time, and the microorganisms on the bottom of the product cannot be directly inactivated in this process. From the perspective of microbiology and radiation physics, the surface of products that are not irradiated may still have the possibility of survival of microorganisms, which will lead to a decrease in the overall sterilization efficiency. Especially for contact lens packaging that strictly requires a sterile environment, the problem of incomplete disinfection is particularly significant. This limitation shows that there is a physical bottleneck in the sterilization of all surfaces by simply relying on the direct light of ultraviolet lamps, and the shielding effect of the contact area will inevitably affect the sterilization efficiency of ultraviolet lamps.

[0014] (III) Beneficial effects Compared with the prior art, the present invention provides a sterilization device for contact lens packaging, which has the following beneficial effects: 1. The sterilization device for contact lens packaging utilizes a sterilization mechanism to place the contact lens packaging products that need to be sterilized on a transparent conveyor belt, and turns on a driving roller to drive the products on the transparent conveyor belt to move to a UV transmitter for UV irradiation and disinfection. At the same time, the ultraviolet rays emitted by the UV transmitter will enter the hollow boss type connecting plate through the transparent conveyor belt, and then be reflected by the high reflective layer on the inner wall of the hollow boss type connecting plate to irradiate and disinfect the products at multiple angles, thereby ensuring that the ultraviolet rays can irradiate multiple angles of the products, improving the sterilization efficiency, reducing blind spots and shadow areas during the sterilization process, and ensuring the safety of the packaged products and a sterile environment.

[0015] 2. The sterilization device for contact lens packaging is set by a ventilation treatment mechanism. The fan is turned on to suck the ozone generated by ultraviolet disinfection into the exhaust pipe through the suction head and the suction pipe and then discharged into the persulfate solution in the hollow boss type connecting plate through the hollow connecting cover and the oblique exhaust port. The reaction force of the oblique exhaust port during jetting drives the hollow connecting cover to rotate, so that the oblique exhaust port rotates and discharges the air with ozone into the persulfate solution. Through this process, the ozone is fully in contact with the persulfate solution, which can effectively degrade the ozone and ensure the safety of the equipment environment.

[0016] 3. The sterilization device for contact lens packaging is set up with a ventilation treatment mechanism. When exhaust is discharged into the solution in the hollow boss type connecting plate, the solution in the hollow boss type connecting plate is stirred to generate liquid flow, so that the ultraviolet rays reflected in the hollow boss type connecting plate produce more refraction angles under the refraction of the fluctuating liquid. This liquid flow and refraction phenomenon can further enhance the propagation path of ultraviolet rays. At the same time, when we set the height of the solution in the hollow boss type connecting plate, it will not exceed the height of the reflective plate, so the reflective function of the reflective plate itself will not be affected.

[0017] 4. The sterilization device used for contact lens packaging is arranged by using a multi-angle mechanism and a rotary exhaust mechanism. When the hollow connecting cover rotates, the cam block is driven to rotate. When the cam block rotates, it periodically abuts against the guide rod, so that the guide rod periodically drives the reflective plate to rotate. This periodic rotation can adjust the reflective plate at multiple angles, thereby changing the reflection direction of ultraviolet rays, ensuring that the ultraviolet rays can irradiate the surface to be disinfected at more angles, and improving the irradiation efficiency and sterilization effect of ultraviolet rays.

[0018] 5. The sterilization device used for contact lens packaging is set up with a ventilation treatment mechanism. At the same time, the purified air in the hollow boss-type connecting plate will move upward, driving the newly generated ozone to continue to move upward into the suction head. Through this circulation method, ozone is continuously and effectively inhaled and introduced into the treatment system, ensuring the continuous degradation of ozone and purification of the air, and further improving the purification efficiency of the entire sterilization device.

[0023] The sterilization mechanism 3 includes an ultraviolet transmitter 31, which is fixedly connected to the top inner wall of the frame 2. A driving roller 32 is arranged on the frame 2. There are two driving rollers 32, and the two driving rollers 32 are symmetrically arranged. A transparent transmission belt 33 is transmission-connected to the two driving rollers 32. A hollow boss-type connecting plate 34 is fixedly connected to the bottom inner wall of the frame 2. The transparent transmission belt 33 is made of transparent material. The transparent transmission belt 33 is made of polytetrafluoroethylene. The hollow boss-type connecting plate 34 is a hollow boss-type. The inner wall of the hollow boss-type connecting plate 34 is made of highly reflective material. The inner wall of the hollow boss-type connecting plate 34 is an aluminum coating for reflecting ultraviolet rays, thereby improving the irradiation efficiency and coverage of ultraviolet rays, thereby enhancing the sterilization effect.

[0024] The ventilation treatment mechanism 4 includes a fan 41, which is fixedly connected to the inner wall of the support body 1, the output port of the fan 41 is fixedly connected to one end of the outlet pipe 42, the other end of the outlet pipe 42 is fixedly connected to the bottom of the hollow boss type connecting plate 34, the input end of the fan 41 is fixedly connected to one end of the inlet pipe 43, the other end of the inlet pipe 43 is fixedly connected to the suction pipe 44, the bottom of the suction pipe 44 is fixedly connected to the suction head 45, the suction head 45 is provided with a wind guide plate for guiding the air to flow to the suction port and enhancing the fluidity of the air, the inner wall of the hollow boss type connecting plate 34 is connected to the inner wall of the outlet pipe 42, and the inner wall of the hollow boss type connecting plate 34 is provided with a sulfur Ozone degrading agent 44 is used to degrade ozone. When the air blown out of the air outlet pipe 42 enters the persulfate solution on the inner wall of the hollow boss type connecting plate 34, the persulfate solution will degrade the ozone in the air and convert it into harmless oxygen. The persulfate solution, as a strong oxidant, can react with ozone to effectively remove ozone and reduce its impact on the environment. This process helps to purify the air, reduce the ozone concentration, and ensure the air safety during the operation of the equipment. Two air suction heads 45 are provided, and the two air suction heads 45 are symmetrically arranged on both sides of the ultraviolet transmitter 31, which are used to evenly absorb the ozone generated during the ultraviolet sterilization process, thereby reducing the potential harm of ozone to the environment and personnel.

[0025] The multi-angle mechanism 5 includes a spring 51, one end of the spring 51 is fixedly connected to the inner wall of the hollow boss type connecting plate 34, and the other end of the spring 51 is fixedly connected to the outer wall of the reflecting plate 52. The bottom of the reflecting plate 52 is hinged with a connecting head 53, so that the reflecting plate 52 can rotate relative to the inner wall of the hollow boss type connecting plate 34 under the connecting action of the connecting head 53. The bottom of the connecting head 53 is fixedly connected to the inner wall of the hollow boss type connecting plate 34. The outer wall of the reflecting plate 52 is provided with a highly reflective material, and the inner wall of the reflecting plate 52 is aluminum-plated. The aluminum-plated coating on the reflecting plate 52 and the aluminum-plated coating on the inner wall of the hollow boss type connecting plate 34 together form a plurality of high-efficiency ultraviolet reflecting surfaces, which can effectively reflect ultraviolet rays, reflect and scatter them inside the equipment, and ensure that the ultraviolet rays are evenly irradiated to various parts of the product. The outer wall of the reflective plate 52 is fixedly connected to a guide rod 54, and the side of the guide rod 54 away from the reflective plate 52 is cylindrical. The rotary exhaust mechanism 6 includes a hollow connecting cover 61, and the hollow connecting cover 61 is rotatably connected to the outer wall of the outlet pipe 42. An oblique exhaust port 62 is arranged at the bottom of the hollow connecting cover 61. There are a plurality of oblique exhaust ports 62, and a circular array of the oblique exhaust ports 62 is arranged at the bottom of the hollow connecting cover 61. The reaction force of the oblique exhaust port 62 when the oblique exhaust port 62 sprays air drives the hollow connecting cover 61 to rotate, so that the oblique exhaust port 62 rotates and sprays air in the persulfate solution of the hollow boss type connecting plate 34, thereby helping the persulfate solution to fully contact with ozone in the air through the rotational motion, thereby improving the ozone degradation efficiency. The outer wall of the hollow connecting cover 61 is fixedly connected to a cam block 63.

[0026] In summary, the sterilization device for contact lens packaging places the contact lens packaging products that need to be sterilized on the transparent conveyor belt 33, turns on the driving roller 32 to drive the products on the transparent conveyor belt 33 to move to the ultraviolet transmitter 31 for ultraviolet irradiation and disinfection. At the same time, the ultraviolet rays emitted by the ultraviolet transmitter 31 will enter the hollow boss type connecting plate 34 through the transparent conveyor belt 33, and then be reflected by the high reflective layer on the inner wall of the hollow boss type connecting plate 34 to irradiate and disinfect the products at multiple angles, thereby ensuring that the ultraviolet rays can irradiate multiple angles of the product, improving the sterilization efficiency, reducing the blind spots and shadow areas during the sterilization process, and ensuring the safety of the packaged products and the sterile environment.

[0027] Turn on the fan 41, and suck the ozone generated by ultraviolet disinfection into the outlet pipe 42 through the suction head 45 and the suction pipe 44, and then discharge it into the persulfate solution in the hollow boss type connecting plate 34 through the hollow connecting cover 61 and the oblique exhaust port 62. The reaction force of the oblique exhaust port 62 during the jetting drives the hollow connecting cover 61 to rotate, so that the oblique exhaust port 62 rotates and discharges the air carrying ozone into the persulfate solution. Through this process, the ozone is fully in contact with the persulfate solution, which can effectively degrade the ozone and ensure the safety of the equipment environment.

[0028] The principle of ozone degradation by persulfate solution is based on the strong oxidizing property of persulfate. When persulfate (such as sodium persulfate or potassium hydrogen persulfate) decomposes in aqueous solution, it will produce oxygen and free radicals, including highly oxidizing superoxide radicals and hydroxyl radicals. These free radicals have strong oxidizing ability and can react with ozone. In this process, persulfate will decompose ozone into oxygen through oxidation reaction. Through this reaction, ozone is effectively degraded, thereby reducing its concentration in the equipment, and ultimately achieving ozone removal and safe control of the equipment environment.

[0029] When exhausting air into the solution in the hollow boss type connecting plate 34, the solution in the hollow boss type connecting plate 34 is stirred to generate liquid flow, so that the ultraviolet rays reflected by the aluminum coating in the hollow boss type connecting plate 34 have more refraction angles under the refraction of the fluctuating liquid. This liquid flow and refraction phenomenon can further enhance the propagation path of the ultraviolet rays. At the same time, when setting the height of the solution in the hollow boss type connecting plate 34, it will not exceed the height of the reflective plate 52, so the reflective function of the reflective plate 52 itself will not be affected.

[0030] The principle of aluminized coating reflecting ultraviolet rays is based on the high reflective properties of aluminum metal. Aluminum has a strong reflective ability, especially in the ultraviolet band. The surface of aluminum metal can effectively reflect ultraviolet rays. Specifically, when ultraviolet rays encounter the surface of aluminum metal, due to the conductivity of aluminum, the energy of ultraviolet rays will be reflected back by the surface instead of being absorbed, resulting in the light being unable to penetrate and being reflected back to the original direction. Aluminized coating covers the surface of the material to form a smooth surface with high reflectivity, which can reflect ultraviolet rays to the greatest extent, thereby improving the efficiency of ultraviolet rays and the sterilization effect.

[0031] When the hollow connecting cover 61 rotates, the cam block 63 is driven to rotate. When the cam block 63 rotates, it periodically abuts against the guide rod 54, so that the guide rod 54 periodically drives the reflective plate 52 to rotate. This periodic rotation can adjust the reflective plate 52 at multiple angles, thereby changing the reflection direction of the ultraviolet rays, ensuring that the ultraviolet rays can irradiate the surface to be disinfected at more angles, thereby improving the irradiation efficiency and sterilization effect of the ultraviolet rays.

[0032] The principle of this process is based on the principles of mechanical movement and optical reflection. First, when the hollow connecting cover 61 rotates, the guide rod 54 is driven to move periodically through the cam block 63, and the guide rod 54 further promotes the rotation of the reflector 52. This periodic rotation converts the rotational motion into the reciprocating motion of the guide rod 54, thereby periodically adjusting the angle of the reflector 52. The adjustment of the reflector 52 at multiple angles changes the reflection direction of the ultraviolet rays. Using the principle of reflective optics, the ultraviolet rays can cover surfaces at different angles after being reflected on the surface of the reflector 52. Ultraviolet rays achieve more comprehensive irradiation through multiple reflections, ensuring that the ultraviolet rays can irradiate all angles that need to be disinfected, thereby improving the irradiation effect of the ultraviolet lamp. In this way, the irradiation range of ultraviolet rays is expanded, avoiding the situation where local areas are not irradiated by ultraviolet rays, and further improving the sterilization efficiency. This design of adjusting the reflection angle also ensures that the ultraviolet rays can cover the surface of the product at the optimal angle, improving the overall effect of the disinfection process.

[0033] At the same time, the purified air from the hollow boss-type connecting plate 34 will flow upward, driving the newly generated ozone to continue to flow upward into the suction head 45. Through this circulation method, ozone is continuously and effectively inhaled and introduced into the treatment system, ensuring the continuous degradation of ozone and purification of the air, further improving the purification efficiency of the entire sterilization device.

[0034] The principle of this process is based on air circulation and ozone degradation. First, when the air in the hollow boss-type connecting plate 34 is purified, the air will flow upward, thereby driving the newly generated ozone to move upward and enter the suction head 45. Through this air circulation, ozone is continuously inhaled and introduced into the treatment system. During this cycle, ozone continuously enters the degradation system and is effectively decomposed into oxygen and other harmless substances by chemically reacting with the persulfate solution, thereby reducing the concentration of ozone.

[0035] In addition, this circulation method also utilizes the continuous contact between airflow and ozone to ensure efficient degradation of ozone and air purification. Through repeated degradation processes, the system can maintain a low ozone concentration while improving purification efficiency, effectively ensuring the safety of the equipment's operating environment.
