Description

Technical Field

[0001] The utility model relates to the technical field of sterilization instruments, and specifically relates to a high-pressure steam sterilization device. Background Technique

[0002] A high-pressure steam sterilizer is a device that uses saturated pressure steam to quickly and reliably disinfect and sterilize items. It is applicable to units in the fields of medical and health, scientific research, agriculture, etc. High-pressure steam sterilizers can be classified into portable high-pressure sterilizers, vertical pressure steam sterilizers, horizontal high-pressure steam sterilizers, etc. according to their styles and sizes. High-pressure steam sterilizers can be used to disinfect and sterilize medical devices, dressings, glassware, solution media, etc. They are also suitable for use as steam cooking equipment in high-altitude areas and for enterprises and institutions to produce high-quality drinking water. They can also be used as equipment for producing high-temperature steam sources.

[0003] At present, the door opening methods of existing high-pressure steam sterilization devices are top-opening and side-opening. The lid of the top-opening type can only be opened from the upper end, and the sterilized samples are generally placed in multiple layers up and down. When taking out the sterilized samples, they can only be taken out sequentially from top to bottom, and it is impossible to take out the sterilized samples specifically. The side-opening type can take out the sterilized samples in time in case of emergency. Sometimes the sterilization time of the sterilized samples is different. Since the side door is generally large, when it is opened, the heat energy inside the box will be lost rapidly, and the samples that need to continue to be sterilized need to be reheated, resulting in waste of energy. Therefore, a high-pressure steam sterilization device is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-pressure steam sterilization device to solve the problems raised in the above background technique.

Specific implementation manner

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution:

[0031] A high-pressure steam sterilization device includes a bottom plate 1 and a sterilization chamber 2.

[0032] Above the bottom plate 1, a sterilization chamber 2 is installed. The front side of the sterilization chamber 2 is rotatably connected to a rotating door 3. The surface of the rotating door 3 is provided with a first handle 5 for driving the rotation of the rotating door 3. The surface of the rotating door 3 is also provided with a rotatable removal plate 4, and a second handle 6 is fixedly connected to the outside of the removal plate 4.

[0033] Inside the sterilization chamber 2, multiple groups of placement plates 8 are installed in a vertical distribution. Above the uppermost placement plate 8, a removal assembly 9 is provided, and the outside of the removal assembly 9 is fixedly connected to the inner wall of the sterilization chamber 2.

[0034] Currently, the door opening methods of existing high-pressure steam sterilization devices are top-opening and side-opening. The lid of the top-opening type can only be opened from the upper end, and the sterilized samples are generally placed in multiple layers up and down. When taking out the sterilized samples, they can only be taken out sequentially from top to bottom, and it is impossible to take out the sterilized samples targeted. While the side-opening type can take out the sterilized samples in time and emergently. Sometimes the sterilization time of the sterilized samples is different. Since the side door is generally large, when it is opened, the heat energy inside the box rapidly loses, and the samples that need to be continuously sterilized need to be reheated, resulting in waste of energy. And when this device is in use, it is externally powered. There is a removal plate 4 on the surface of the rotating door 3, and there is a placement plate 8 for placing sterilized samples with a longer sterilization time and a removal component 9 for placing sterilized samples with a shorter sterilization time inside the sterilization box 2. When taking out the samples with a shorter sterilization time of the sterilized samples, by opening the removal plate 4 on the surface of the rotating door 3, the sterilized samples can be conveniently taken out through the removal component 9. This setting does not require the whole rotating door 3 to be opened, avoiding a large amount of energy waste, and the samples with a longer sterilization time inside the sterilization box 2 can be continuously sterilized. And when taking out the sterilized samples above the placement plate 8, by opening the rotating door 3, it is convenient to take out the sterilized samples inside the placement plate 8;

[0035] In this embodiment, a first handle 5 is provided on the outside of the rotating door 3, which facilitates the rotation and opening of the rotating door 3 through the first handle 5. And a second handle 6 is installed on the outside of the removal plate 4. When taking out the samples with a shorter sterilization time, by the second handle 6, the removal plate 4 can be rotated, then reducing the open area of the equipment and avoiding the waste of heat energy in vain, and the samples above the lower placement plate 8 can continue the sterilization work.

[0036] Embodiment 2

[0037] This embodiment is an improvement made to Embodiment 1. Please refer to Figure 4 , specifically, a sealing frame 10 is fixedly connected to the periphery of the side of the removal plate 4 facing the inside of the sterilization box 2, and the sealing frame 10 is arranged in a rectangular frame shape. The outside of the sealing frame 10 is in close contact with the rotating door 3.

[0038] The sealing frame 10 provided on the outside of the removal plate 4 can ensure that the removal plate 4 and the sterilization box 2 are sealed, avoiding heat leakage;

[0039] In this embodiment, the sealing frame 10 is embedded in the periphery of the rear side of the removal plate 4, and the outside of the sealing frame 10 cooperates with the rotating door 3, which can ensure the sealing quality of the equipment and avoid energy leakage.

[0040] Embodiment 3

[0041] This embodiment is an improvement made to Embodiment 2. Please refer to Figure 1 , specifically, an observation plate 7 arranged in a rectangular shape is also embedded on the surface of the rotating door 3.

[0042] The above-mentioned observation plate 7 is made of transparent acrylic board.

[0043] When taking out the sterilized sample above the taking-out component 9, people can observe the state of the sterilized sample inside the taking-out component 9 through the transparent observation plate 7, which is convenient for the subsequent taking-out work of the sterilized sample.

[0044] Embodiment 4

[0045] This embodiment is an improvement made to Embodiment 3. Please refer to Figure 3 , specifically, the above-mentioned taking-out component 9 includes a mounting frame 901, a motor 902 and a threaded shaft 903. The outside of the above-mentioned mounting frame 901 is fixedly connected to the sterilization box 2. A motor 902 is fixedly connected inside the above-mentioned mounting frame 901. The end of the main shaft of the above-mentioned motor 902 is fixedly connected to a threaded shaft 903. A threaded sleeve 904 is spirally connected to the outside of the above-mentioned threaded shaft 903, and the other end of the threaded sleeve 904 is fixedly connected to a first sealing plate 905. The other end of the above-mentioned first sealing plate 905 is fixedly connected to a moving frame 906.

[0046] The side of the above-mentioned moving frame 906 away from the first sealing plate 905 is fixedly connected to a second sealing plate 907.

[0047] The upper part of the above-mentioned mounting frame 901 is open.

[0048] The above-mentioned taking-out component 9 is located directly behind the taking-out plate 4.

[0049] When the taking-out plate 4 is opened, by starting the motor 902 to drive the threaded shaft 903 to rotate, the threaded shaft 903 drives the threaded sleeve 904 to move, and the threaded sleeve 904 can drive the first sealing plate 905 and the moving frame 906 to move. At this time, the moving frame 906 can extend out of the sterilization box 2 through the taking-out plate 4. At this time, it is convenient to take out the sterilized sample inside the moving frame 906. The provided first sealing plate 905 abuts against the inner side of the rotating door 3 to block the open part where the taking-out plate 4 is located and avoid waste of energy leakage;

[0050] In this embodiment, when the device needs to sterilize a sample with a short sterilization time, the second handle 6 is driven to drive the extractor 14 to rotate, and then the extraction assembly 9 is started. The moving frame 906 in the extraction assembly 9 is slowly pushed out. Since the area of the second sealing plate 907 is smaller than that of the first sealing plate 905, at this time, the second sealing plate 907 can extend out through the area where the extraction plate 4 cooperates with the rotating door 3, and the moving frame 906 extends out smoothly. The first sealing plate 905 is located inside the rotating door 3 and contacts the rotating door 3. At this time, it is convenient to take out the sample inside the moving frame 906. At the same time, under the action of the first sealing plate 905, the inside of the sterilization chamber 2 is in a relatively sealed state, and other samples can continue to be sterilized, avoiding waste of heat resources. The second sealing plate 907 is made of heat-insulating material. When it extends into the sterilization chamber 2, its temperature drops rapidly, avoiding scalding personnel.
