Description

Technical Field

[0001] This utility model relates to the field of ultraviolet sterilization equipment technology, and in particular to an overflow sterilization device. Background Technology

[0002] A flow-through sterilization device is a type of equipment used for sterilizing fluid materials, widely used in the food, beverage, and pharmaceutical industries. Flow-through sterilization devices include flow-through ultraviolet (UV) sterilizers. The flow-through UV sterilizer is a common type of flow-through sterilization device; it utilizes the sterilizing effect of UV lamps to disinfect flowing liquids. Traditional flow-through UV sterilizers require manual insertion of the lamp tubes, and uneven force during installation can easily cause the lamp tubes to break. Due to their slender and fragile nature, when subjected to unbalanced forces, excessive local pressure can cause the lamp tube to rupture instantly if it exceeds its bearing capacity. Even if it doesn't break immediately, stress concentration can damage the internal structure, creating potential hazards. During subsequent use, factors such as lamp heat and water flow impact will continue to exacerbate this internal damage, eventually leading to lamp tube breakage. Utility Model Content

[0003] The purpose of this invention is to address the problem that traditional flow-through ultraviolet germicidal lamp tubes are prone to breakage when manually installed due to uneven force. Even if they do not break immediately, the internal parts will be damaged, which will exacerbate the problem during subsequent use and lead to further breakage. Therefore, this invention proposes a flow-through sterilization device.

[0004] The technical solution of this utility model is as follows: A flow-through sterilization device includes a flow-through ultraviolet sterilizer and an ultraviolet lamp tube movably inserted into one end of the flow-through ultraviolet sterilizer. It further includes: a retaining sleeve fixedly connected to the outer wall of one end of the flow-through ultraviolet sterilizer to support the sliding of the ultraviolet lamp tube; a sliding sleeve movably fitted onto one end of the flow-through ultraviolet sterilizer; a sleeve plate disposed on the end of the flow-through ultraviolet sterilizer near the sliding sleeve, the sleeve plate having multiple holes for fitting onto the retaining sleeve; and a rotating mechanism installed on the outer wall of the sleeve plate to automatically insert the ultraviolet lamp tube into the flow-through ultraviolet sterilizer.

[0005] Optionally, the rotating mechanism includes multiple pairs of rotating seats corresponding to the sleeve holes, which are fixedly connected to the outer wall of the sleeve plate. Each rotating seat is rotatably connected to a U-shaped rotating frame. A rubber roller is rotatably connected to the middle of one end of the U-shaped rotating frame. A bracket is fixedly connected to the outer wall of one of the U-shaped rotating frames. A motor is fixedly connected to the bracket. The output shaft of the motor passes through the U-shaped rotating frame and is fixedly connected to one end of the rubber roller.

[0006] Optionally, a support plate is fixedly connected to the middle of the U-shaped rotating frame, and a positioning sleeve corresponding to the sleeve hole is fixedly connected to the outer wall of the sleeve plate. A return spring is provided in the middle of both the positioning sleeve and the support plate. One end of the return spring is fixedly connected to the support plate, and the other end of the return spring is fixedly connected to the outer wall of the positioning sleeve.

[0007] Optionally, the rubber roller is provided with an arc-shaped groove that fits tightly against the outer wall of the ultraviolet lamp tube.

[0008] Optionally, a connecting plate is fixedly connected to the end of the sliding sleeve away from the sleeve plate, and corresponding inlet and outlet pipes are fixedly connected to the outer walls of both ends of the flow-through ultraviolet sterilizer. An elastic clamp that locks the inlet and outlet pipes is fixedly connected to the end of the connecting plate away from the sliding sleeve.

[0009] Optionally, the outer wall of the sleeve is provided with multiple anti-slip patterns arranged in a linear pattern.

[0010] Optionally, the outer wall of the sliding sleeve away from the connecting plate is fixedly connected to a plurality of connecting frames arranged in a circumferential array, and the end of each connecting frame away from the sliding sleeve is fixedly connected to the sleeve plate.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This invention utilizes a combination of a clamping sleeve, sliding sleeve, sleeve plate, sleeve hole, and rotating mechanism. When inserting the ultraviolet lamp into the flow-through ultraviolet sterilizer, starting the motor allows the ultraviolet lamp to be automatically inserted in a uniform, slow, and stable manner. This not only effectively reduces the risk of breakage and avoids potential internal damage, but also significantly reduces replacement costs and maintenance frequency, ensuring the continuous and stable operation of the sterilization equipment and making each sterilization operation precise and efficient. Furthermore, the flow-through ultraviolet sterilizer employs an automated insertion and removal system for the ultraviolet lamp, enabling rapid lamp replacement and minimizing equipment downtime.

[0024] Example

[0025] like Figures 1 to 4 As shown, the present invention proposes a flow-through sterilization device, including a flow-through ultraviolet sterilizer 1 and an ultraviolet lamp tube 12 movably inserted into one end of the flow-through ultraviolet sterilizer 1. A retaining sleeve 11 supporting the sliding of the ultraviolet lamp tube 12 is fixedly connected to the outer wall of one end of the flow-through ultraviolet sterilizer 1. A sliding sleeve 2 is movably fitted onto one end of the flow-through ultraviolet sterilizer 1. The inner wall of the sliding sleeve 2 in contact with the flow-through ultraviolet sterilizer 1 is provided with a rubber pad for anti-slip. Its function is to ensure that the sliding sleeve 2 can slide on one end of the flow-through ultraviolet sterilizer 1, but cannot slide easily. It can only slide slowly with force, which is the same principle as the insertion and removal of a syringe. Multiple connecting frames 31 arranged in a circumferential array are fixedly connected to the outer wall of the sliding sleeve 2 away from the connecting plate 21. The ends of the connecting frames 31 away from the sliding sleeve 2 are all fixedly connected to the sleeve plate 3. A sleeve plate 3 is provided at the end of the flow-through ultraviolet sterilizer 1 close to the sliding sleeve 2. Multiple sleeve holes 32 are opened on the sleeve plate 3 to fit onto the retaining sleeve 11.

[0026] Among them, such as Figure 1 , Figure 3 and Figure 4 As shown, a rotating mechanism is installed on the outer wall of the sleeve plate 3 to automatically insert the ultraviolet lamp tube 12 into the flow-through ultraviolet sterilizer 1. The rotating mechanism includes multiple pairs of rotating seats 35 fixedly connected to the outer wall of the sleeve plate 3, corresponding to the sleeve holes 32. Each rotating seat 35 is rotatably connected to a U-shaped rotating frame 34. A rubber roller 36 is rotatably connected to the middle of one end of the U-shaped rotating frame 34. The rubber roller 36 is made of rubber, and its function is to increase the friction when in contact with the ultraviolet lamp tube 12 and to prevent the ultraviolet lamp tube 12 from being crushed due to the material being too hard. The rubber roller 36 has an arc-shaped groove that fits tightly against the outer wall of the ultraviolet lamp tube 12. The arc-shaped groove ensures that the contact surface is increased when the rubber roller 36 is in contact with the ultraviolet lamp tube 12, and prevents the ultraviolet lamp tube 12 from being crushed due to excessive local pressure caused by a small contact surface. One of the U-shaped rotating frames 34 has a bracket 39 fixedly connected to its outer wall. A motor 40 is fixedly connected to the bracket 39. The output shaft of the motor 40 passes through the U-shaped rotating frame 34 and is fixedly connected to one end of the rubber roller 36.

[0027] In addition, such as Figure 3 and Figure 4 As shown, a support plate 37 is fixedly connected to the middle of the U-shaped rotating frame 34, and a positioning sleeve 33 corresponding to the sleeve hole 32 is fixedly connected to the outer wall of the sleeve plate 3. Both the positioning sleeve 33 and the support plate 37 are equipped with a return spring 38 in their middle sections. The return spring 38 ensures that the rubber roller 36 on the U-shaped rotating frame 34 is always tightly clamped to the ultraviolet lamp tube 12 under normal conditions. One end of the return spring 38 is fixedly connected to the support plate 37, and the other end of the return spring 38 is fixedly connected to the outer wall of the positioning sleeve 33.

[0028] It is worth noting that, such as Figure 1 and Figure 3 As shown, a connecting plate 21 is fixedly connected to the end of the sliding sleeve 2 away from the sleeve plate 3. Corresponding inlet and outlet pipes are fixedly connected to the outer walls of both ends of the flow-through ultraviolet sterilizer 1, and flanges are provided at the top of each pipe. An elastic clamp 22, made of plastic, is fixedly connected to the end of the connecting plate 21 away from the sliding sleeve 2 to hold the inlet and outlet pipes in place. When the elastic clamp 22 is not holding the inlet and outlet pipes in place, the rubber roller 36 tightly holds the ultraviolet lamp 12 in place, allowing the ultraviolet lamp 12 to be freely inserted and removed from the sleeve 11 by the drive of the motor 40. When the elastic clamp 22 holds the inlet and outlet pipes in place, the rubber roller 36 holds the sleeve 11 in place, allowing the ultraviolet lamp 12 to be freely inserted and removed from the sleeve 11.

[0029] Furthermore, such as Figure 3 As shown, the outer wall of the slide sleeve 2 is provided with several anti-slip textures 23 arranged in a linear pattern. The anti-slip textures 23 are used to increase the unevenness of the outer wall of the slide sleeve 2, so as to increase the friction when the outer wall of the slide sleeve 2 comes into contact with the hand, and prevent the slide sleeve 2 from sliding when manually sliding.

[0030] In this embodiment, when using the overflow sterilization device, such as Figure 1 As shown, firstly, slide the sliding sleeve 2 at the end of the flow-through ultraviolet sterilizer 1. The sliding sleeve 2 sequentially drives the connecting plate 21 and the elastic clamp 22 to move until the elastic clamp 22 is engaged on the inlet and outlet pipes. At the same time, the sliding sleeve 2 also drives the sleeve plate 3 to move through multiple connecting brackets 31. The sleeve plate 3 drives multiple pairs of U-shaped rotating brackets 34 to move until the U-shaped rotating brackets 34 drive the rubber rollers 36 to tightly press against the outer wall of the end of the ultraviolet lamp tube 12. At this time, insert each ultraviolet lamp tube 12 into the interior of the flow-through ultraviolet sterilizer 1 in sequence. Then, slide the sliding sleeve 2 away from the flow-through ultraviolet sterilizer 1, so that the elastic clamp 22 is disengaged from the inlet and outlet pipes, and the sleeve plate 3 drives the multiple pairs of U-shaped rotating brackets 34 on it to disengage from the outer wall of the end of the ultraviolet lamp tube 12. Then, the multiple pairs of U-shaped rotating brackets 34 drive the rubber rollers 36 on them to press tightly against the outer wall of the ultraviolet lamp tube 12, and so on. Figure 1The state shown is correct. Finally, start the motor 40 on the corresponding bracket 39. The motor 40 drives the corresponding rubber roller 36 to rotate. Significant friction is generated between one of the rubber rollers 36 and the ultraviolet lamp 12, and the other rubber roller 36 holds the ultraviolet lamp 12 in place. This allows the pair of rubber rollers 36 to evenly and smoothly insert the ultraviolet lamp 12 into the flow-through ultraviolet sterilizer 1, which is quick and convenient. The principle of inserting each ultraviolet lamp 12 into the flow-through ultraviolet sterilizer 1 is the same as described above, and will not be repeated here.

Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
