Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulsed vacuum steam sterilizer technology, and in particular to a steam inlet pipe device for the sterilization chamber of a pulsed vacuum steam sterilizer. Background Technology
[0002] Currently, in the pulsed vacuum steam sterilizer, after it is in operation, high-pressure steam enters the sterilization chamber through the steam inlet valve. The steam inlet pipe is divided into one or two lines leading to the steam inlet on the side of the sterilization chamber. The pipe size has not changed. Therefore, the steam impact force entering the sterilization chamber is very large, and condensate will splash onto the items. This creates the potential risk of occasional wet packaging of items in the same batch. Once wet packaging occurs, the items must be unpacked, dried, repackaged, and sterilized again. This affects the overall sterilization efficiency and production needs, resulting in waste of resources and excessive consumption. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] Reference Figure 1 A steam inlet pipe device for the sterilization chamber of a pulsed vacuum steam sterilizer is proposed. This device aims to provide a highly efficient and stable steam inlet pipe system for the pulsed vacuum steam sterilizer. Through multi-stage buffering, filtration, and condensate separation design, it ensures that steam enters the sterilization chamber 7 at suitable temperature, pressure, and dryness, preventing condensate contamination of the sterilized items and improving sterilization efficiency and production efficiency. Specifically:
[0020] The device includes a steam inlet pipe for use with the sterilization chamber 7 of the pulsed vacuum steam sterilizer. The steam inlet pipe includes a vertically arranged buffer diffuser 1, which is made of stainless steel and sealed at the top and bottom with sealing plates. A steam inlet 2 is provided on the upper part of one side of the buffer diffuser 1, which can be connected to an external steam source pipe through a flange to facilitate the input of steam. A steam inlet valve 6 is installed at the steam inlet 2 on the buffer diffuser 1. A steam outlet 3 is provided on the lower part of the other side of the buffer diffuser 1 for communication with the steam inlet 8 of the sterilization chamber 7 of the pulsed vacuum steam sterilizer. It can be flexibly connected to the steam inlet 8 of the sterilization chamber 7 through a corrugated compensator to compensate for thermal expansion and vibration, and facilitate the delivery of steam to the sterilization chamber 7 of the pulsed vacuum steam sterilizer.
[0021] The diameter of the buffer diffuser 1 is larger than that of the steam inlet 2, which facilitates the step-by-step reduction of the steam velocity through abrupt changes in cross-sectional area. At the same time, since the buffer diffuser 1 is set vertically, the vertical space can be used to extend the steam residence time and promote the natural settling of condensate.
[0022] A number of buffer filter screens 5 are arranged from top to bottom inside the buffer diffuser pipe 1 between the steam inlet 2 and the steam outlet 3. The buffer filter screens 5 are made of 304 stainless steel sintered felt and have both mechanical filtration and droplet capture functions. When steam passes through, droplets impact the surface of the filter screen under inertia and converge downward along the mesh structure. At the same time, it can also reduce the impact force of steam. Preferably, there are 2-4 buffer filter screens 5. The buffer filter screens 5 are arranged at equal intervals from top to bottom inside the buffer diffuser pipe 1, or the distance between two adjacent buffer filter screens 5 decreases from top to bottom.
[0023] A condensate collection port 4 is provided at the bottom of the buffer diffusion tube 1. A condensate collection chamber is formed in the buffer diffusion tube 1 between the steam outlet 3 and the condensate collection port 4. This not only prevents the condensate in the buffer diffusion tube 1 from being discharged into the sterilization chamber 7 of the pulsed vacuum steam sterilizer through the steam outlet 3, but also ensures the efficient collection of condensate. Preferably, the condensate collection port 4 of the buffer diffusion tube 1 is connected to the condensate collection port 9 of the sterilization chamber 7 of the pulsed vacuum steam sterilizer, so as to facilitate the subsequent collection of condensate from the sterilization chamber 7 of the pulsed vacuum steam sterilizer and discharge it through the main outlet 10 of the sterilization chamber 7 of the pulsed vacuum steam sterilizer.
[0024] In actual use, the diameter of the steam inlet 2 is 15mm, the diameter of the buffer diffuser 1 is 90mm, the diameter of the steam outlet 3 is 65mm, and the diameter of the condensate collection port 4 of the buffer diffuser 1 is 15mm. Theoretically, based on a maximum steam pressure difference of 400.0KPa entering the sterilizer, since the area of the steam inlet 2 (∅15) is much smaller than the area of the steam outlet 3 (∅65), approximately 18.8 times, the pressure can be reduced to 21.3KPa under the maximum pressure condition after passing through this device, which can effectively reduce the steam impact force entering the sterilization chamber 7 of the pulsating vacuum steam sterilizer.
[0025] A layer of high-temperature resistant insulation cotton is also covered on the outside of the buffer diffuser tube 1 to facilitate the insulation treatment of the buffer diffuser tube 1 and reduce the amount of condensate generated.
[0026] The steam inlet pipe device for the sterilization chamber 7 of the pulsed vacuum steam sterilizer provided in this application is installed on the side of the pulsed vacuum steam sterilizer and placed vertically. After the pulsed vacuum steam sterilizer is running, the door slot is sealed, the steam inlet valve 6 is opened, and high-temperature and high-pressure steam enters the buffer diffuser 1 through the steam inlet 2. In the buffer diffuser 1, the steam pressure is reduced, and after being filtered by the buffer filter screen, the pressure is further reduced. Then, it enters the sterilization chamber 7 of the pulsed vacuum steam sterilizer through the steam outlet 3. At the same time, the condensate generated is collected along the wall of the buffer diffuser 1 under its own weight and enters the condensate collection chamber. It then flows automatically through the condensate collection port 4 to the condensate collection port 9 of the sterilization chamber 7 of the pulsed vacuum steam sterilizer and is finally discharged through the main outlet 10 of the sterilization chamber 7 of the pulsed vacuum steam sterilizer.
