Description

Technical Field

[0001] This utility model belongs to the field of sterilization equipment technology and relates to a sterilization device. Background Technology

[0002] In the fields of medical treatment, biopharmaceuticals, food processing, and scientific research, sterilization is a crucial step in ensuring product safety, preventing cross-contamination, and guaranteeing the reliability of experimental results. As industry standards continue to rise, the requirements for sterilization efficiency, thoroughness, and operational safety are becoming increasingly stringent. Currently, high-pressure steam sterilization has become the most widely used physical sterilization method due to its advantages such as strong bactericidal ability, rapid action, good penetration, and no residual toxicity. It is particularly suitable for sterilizing instruments, culture media, dressings, glassware, and other items that are resistant to high temperatures and humidity.

[0003] The core equipment for achieving high-pressure steam sterilization is the autoclave (also known as a high-pressure steam sterilizer). Its working principle involves pressurizing and heating saturated steam within a sealed chamber (typically 121℃, 0.1MPa or 134℃, 0.2MPa). This high-temperature, high-humidity environment denatures microbial proteins and inactivates their enzyme systems, thus achieving thorough sterilization. This equipment has a mature structure and stable sterilization effect, and is widely deployed in hospital disinfection supply centers, laboratories, and production workshops at all levels.

[0004] However, traditional autoclaves still face significant operational bottlenecks in practical applications: the entire sterilization process is highly dependent on manual operation. Operators must manually load the items to be sterilized one by one or basket by basket into the sterilization chamber, and then manually remove them after sterilization. When faced with large-volume, high-frequency sterilization needs (such as centralized processing of surgical instruments in hospitals or sterilization of multiple batches of culture media in laboratories), this mode is not only cumbersome and inefficient, but also labor-intensive and costly. Utility Model Content

[0005] The purpose of this invention is to provide a sterilization device that adopts a tunnel-type sterilization design, which can more easily and automatically transport the device into the sterilization tunnel for sterilization, thereby improving work efficiency and reducing the burden on personnel.

[0006] To solve the above-mentioned technical problems, this utility model provides a sterilization device, including a support frame. A horizontal conveyor frame is provided at the upper end of the support frame. A sterilization tunnel, open at both ends and extending along its length, is provided in the middle of the upper end of the horizontal conveyor frame. Both ends of the horizontal conveyor frame extend beyond the sterilization tunnel. A drive shaft is rotatably connected to both ends of the horizontal conveyor frame. A drive motor for driving one of the drive shafts is installed at one end of the horizontal conveyor frame. A conveyor belt encasing the two drive shafts is provided inside the horizontal conveyor frame. The two open ends of the sterilization tunnel are slidably connected... The sterilization tunnel has vertically arranged sealing covers, the bottom of which can contact the conveyor belt. Each opening of the sterilization tunnel is equipped with two vertically arranged hydraulic lifting cylinders on both sides. Each sealing cover is provided with a connecting end that connects to the telescopic shaft of the corresponding two hydraulic lifting cylinders. One end of the sterilization tunnel is connected to a steam inlet pipe, which is equipped with a first solenoid valve. The end of the sterilization tunnel away from the steam inlet pipe is connected to an exhaust pipe, which is equipped with a second solenoid valve. A humidity sensor is installed on the inner wall of the sterilization tunnel near the exhaust pipe.

[0007] By adopting the above technical solution, when sterilization is required, the items to be sterilized are first placed on the conveyor belt, and the drive motor is started. The drive motor moves the conveyor belt, transporting the items to be sterilized into the sterilization tunnel. At this time, the hydraulic lifting cylinder is activated, driving the sealing cover to descend and sealing the sterilization tunnel. Subsequently, the steam generator injects high-temperature steam into the sterilization tunnel through the steam inlet pipe, and the first solenoid valve controls the amount of steam entering. During the steam injection process, the exhaust pipe discharges the original air in the sterilization tunnel. When the humidity sensor detects the approaching steam, it controls the second solenoid valve to close, filling the sterilization tunnel with high-temperature steam to achieve the temperature and humidity conditions required for sterilization. When the sterilization time reaches the preset value, the hydraulic lifting cylinder is activated again, driving the sealing cover to rise and opening the sterilization tunnel. The drive motor then drives the conveyor belt to transport the sterilized items out of the sterilization tunnel from the other end, completing the entire sterilization process.

[0008] The present invention is further configured such that a support platform located within the conveyor belt is provided inside the horizontal conveyor frame, the support platform is located between two drive shafts, and the upper end of the support platform is in contact with the upper side of the conveyor belt.

[0009] The present invention is further provided with a plurality of sealing strips distributed along the length direction on the outer side of the conveyor belt, and the cross section of each sealing strip is C-shaped to match the sealing cover plate.

[0010] The present invention is further configured such that vertical slide rails are provided on both sides of each opening end of the sterilization tunnel, and vertical slide bars that are slidably connected to the corresponding vertical slide rails are provided on both sides of each sealing cover plate.

[0011] The present invention is further provided that the sterilization tunnel is equipped with a pressure sensor for detecting the internal pressure.

[0012] The present invention is further provided that the sterilization tunnel is equipped with a temperature sensor for detecting its internal temperature.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, this sterilization equipment adopts a tunnel-type design, achieving seamless integration of automatic conveying of items to be sterilized and the sterilization process, greatly improving work efficiency and reducing the burden on personnel. Compared to traditional autoclaves that rely on manual loading and unloading, this equipment automatically completes the entry and exit of items via a conveyor belt, making it particularly suitable for large-volume, high-frequency sterilization needs, such as centralized processing of hospital surgical instruments or sterilization of multiple batches of culture media in laboratories, significantly reducing operational complexity and labor intensity.

[0015] Secondly, the equipment uses a hydraulic lifting cylinder to drive the sealing cover to quickly seal and open the sterilization tunnel. Combined with precise control of the steam inlet pipe and exhaust pipe, it ensures that the required high temperature and high humidity environment can be quickly reached and maintained inside the sterilization tunnel, avoiding excessive air inside the sterilization tunnel that would lead to poor steam sterilization effect.

[0021] The sterilization device proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0022] Example, refer to Figure 1-4 A sterilization device includes a support frame 1. A horizontal conveyor frame 2 is provided at the upper end of the support frame 1. A sterilization tunnel 3 is provided in the middle of the upper end of the horizontal conveyor frame 2, which is open at both ends and runs along its length. The two ends of the horizontal conveyor frame 2 extend out of the sterilization tunnel 3. A horizontally arranged drive shaft 4 is rotatably connected to both ends of the horizontal conveyor frame 2. A drive motor 5 for driving one of the drive shafts 4 is installed at one end of the horizontal conveyor frame 2. A conveyor belt 6 is provided inside the horizontal conveyor frame 2, which is wrapped around the two drive shafts 4. A support platform 7 is provided inside the horizontal conveyor frame 2 and located inside the conveyor belt 6. The support platform 7 is located between the two drive shafts 4. The upper end of the support platform 7 contacts the upper side of the conveyor belt 6, so that the conveyor belt 6 will not sag due to its own weight.

[0023] Each of the two opening ends of the sterilization tunnel 3 is slidably connected to a vertically arranged sealing cover plate 8. The lower edge of each sealing cover plate 8 can contact the conveyor belt 6. Multiple sealing strips 9 are arranged along the length of the conveyor belt 6. The cross-section of each sealing strip 9 is C-shaped to match the sealing cover plate 8, so that the sealing cover plate 8 can effectively seal after it descends and contacts the sealing strip 9. Each opening end of the sterilization tunnel 3 is vertically arranged with a vertical slide rail 10 on both sides. Each sealing cover plate 8 is provided with a vertical slide bar 11 that is slidably connected to the corresponding vertical slide rail 10 on both sides. Each opening end of the sterilization tunnel 3 is installed with a vertically arranged hydraulic lifting cylinder 12 on both sides. Each sealing cover plate 8 is provided with two connecting ends 13 that are respectively connected to the telescopic shafts of the two corresponding hydraulic lifting cylinders 12. The sealing cover plate 8 is raised and lowered by the telescopic movement of the hydraulic lifting cylinders 12, so as to open and close the two opening ends of the sterilization tunnel 3.

[0024] One end of the sterilization tunnel 3 is connected to a steam inlet pipe 14, which is used to connect to a steam generator. A first solenoid valve 15 is installed on the steam inlet pipe 14. The end of the sterilization tunnel 3 away from the steam inlet pipe 14 is connected to an exhaust pipe 16, which is equipped with a second solenoid valve 17. A humidity sensor 18 is installed on the inner wall of the sterilization tunnel 3 near the exhaust pipe 16. The exhaust pipe 16 is used to expel the original air inside the tunnel when steam is injected. When the humidity sensor 18 detects the approaching steam, it controls the second solenoid valve 17 to close, filling the sterilization tunnel 3 with high-temperature steam. A pressure sensor 19 is installed on the sterilization tunnel 3 to detect its internal pressure, and a temperature sensor 20 is installed on the sterilization tunnel 3 to detect its internal temperature.

[0025] Working Principle: When sterilization is required, the items to be sterilized are first placed on the conveyor belt 6. The drive motor 5 is started, and the drive motor 5 drives the conveyor belt 6 to move, transporting the items to be sterilized into the sterilization tunnel 3. At this time, the hydraulic lifting cylinder 12 is activated, driving the sealing cover 8 to descend. The sealing cover 8 makes tight contact with the sealing strip 9 on the outside of the conveyor belt 6, achieving a seal in the sterilization tunnel 3. Subsequently, the steam generator injects high-temperature steam into the sterilization tunnel 3 through the steam inlet pipe 14, and the first solenoid valve 15 controls the amount of steam entering. During the steam injection process, the exhaust pipe 16 discharges the original air in the sterilization tunnel 3. When the humidity sensor 18 detects the approaching steam, it controls the second solenoid valve 17 to close, filling the sterilization tunnel 3 with high-temperature steam to achieve the temperature and humidity conditions required for sterilization. During the sterilization process, the pressure sensor 19 and the temperature sensor 20 monitor the pressure and temperature inside the sterilization tunnel 3 in real time to ensure that the sterilization process is carried out under suitable conditions. Once the sterilization time reaches the preset value, the hydraulic lifting cylinder 12 starts again, driving the sealing cover 8 to rise and open the opening end of the sterilization tunnel 3. The drive motor 5 drives the conveyor belt 6 to transport the sterilized items out of the sterilization tunnel 3 from the other end, completing the entire sterilization process.

[0026] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.
