Description

Technical Field

[0001] This utility model relates to the field of steam sterilization equipment technology, and more specifically, to a layered barrel-in-barrel sterilizer. Background Technology

[0002] In laboratory research, sterilization of materials such as mushroom substrate fragments and soil is a routine procedure. Traditional methods often involve loading the materials into heat-resistant cloth bags and placing them in an autoclave for sterilization, but this method has significant drawbacks: Firstly, when the filter bag is exposed to high temperature and high humidity environment (such as 121℃ and above 0.1MPa) for a long time, its fiber structure is prone to hydrolysis and oxidative degradation, resulting in a high breakage rate and short life after repeated use. This not only increases the cost of consumables, but may also cause material leakage due to filter bag rupture, contaminating the sterilization environment and interfering with the experimental results. Secondly, laboratories often need to process multiple materials or experimental instruments (such as culture media, glassware, etc.) at the same time. Traditional sterilization containers (such as single cloth bags or metal trays) lack layered design, have low space utilization, resulting in limited sterilization capacity per batch and requiring multiple batch operations, which is inefficient.

[0003] Therefore, in view of the above-mentioned technical defects, it is necessary to propose a layered barrel-in-barrel sterilizer. Utility Model Content

[0004] The present invention aims to propose a layered container-in-container sterilizer to solve the problems of short container life and inability to process multiple materials or multiple experimental instruments simultaneously in the existing technology.

[0005] This utility model provides a layered, barrel-in-barrel sterilizer, comprising: The sterilization tank body has a mounting part that is slidably arranged along the inner wall surface. The mounting part has at least three mounting plates that are slidably arranged along the inner end surface. The mounting plates are mutually adapted to the inner wall surface of the mounting part. A bottom rod is fixedly arranged at the lower end of the outer wall of the mounting plate in the horizontal direction. A mounting block is arranged on the lower left side of the bottom rod, and a support rod is hinged below the mounting block. The tray is placed on the upper surface of the base rod, and multiple ventilation holes are evenly distributed on the inner wall of the tray from the bottom end face to the bottom end face. A shielding assembly, the lower surface of which is connected to a support rod, is used so that the support rod can move the shielding assembly to the left side of the tray.

[0006] Preferably, the shielding component is a baffle, wherein the baffle has an arc-shaped structure, and the lower surface of the baffle is connected to the support rod, and a tension spring is provided between the top middle of the support rod and the lower surface of the bottom rod.

[0007] Preferably, an arc-shaped support block is provided at the front and rear sides of the upper end of the outer wall of the mounting plate, and a limit block is also provided on the left side of the support block along the lower surface of the bottom rod. In use, the limit block can limit the rotation range of the support rod.

[0008] Preferably, the mounting part is a semi-circular plate structure, and an extension is provided at the lower end of the mounting part, wherein the extension is integrally formed with the mounting part, and a circular ring structure can be formed between the extension and the mounting part.

[0009] Preferably, the mounting part has a vertical groove extending from the outer wall to the inner wall, and a positioning strip is vertically and fixedly installed on one side of the groove along the inner wall. The positioning strip has multiple positioning holes evenly distributed from top to bottom. A slider is slidably arranged on the other side of the inner side of the groove. One end of the slider is connected to the mounting plate, and the other end extends toward the positioning strip. A positioning pin is also slidably arranged and passes through the slider, and the positioning pin is also arranged opposite to the positioning hole.

[0010] Preferably, a circular connecting groove is provided at the top of the sterilization barrel body, and a bottle cap is threaded onto the connecting groove.

[0011] Preferably, both the mounting section and the tray are provided with corresponding handles at the upper end of the inner wall.

[0012] The beneficial effects of this utility model are as follows: 1. Compared with existing technologies, this solution, through the design of the mounting section, mounting plate, base rod and support block, enables multiple trays to be quickly installed on the support plate. After the trays are installed, the user can quickly put them into the sterilization tank through the mounting section, thereby significantly improving the efficiency of tray arrangement and removal, and improving the convenience and efficiency of sterilization operation.

[0013] 2. This solution cleverly incorporates a mounting block, support rod, tension spring, and baffle at the base position. This design allows the baffle to extend flexibly to the lower left side of the pallet, effectively limiting the pallet's position after extension. Furthermore, the hinged design of the support rod further enhances the equipment's flexibility. When the pallet needs to be moved to the left, a pushing force can be applied directly to the baffle. Under this pushing force, the support rod drives the baffle away from the pallet, enabling the pallet to be quickly removed. This innovative design significantly improves the ease of operation.

[0024] As attached Figure 1 To be continued Figure 4 As shown: A layered barrel-in-barrel sterilizer includes a sterilization barrel body 1. The sterilization barrel body 1 has a mounting part 2 slidably disposed along its inner wall surface. The mounting part 2 has at least three mounting plates 3 slidably disposed along its inner end surface. The mounting plates 3 are mutually adapted to the inner wall surface of the mounting part 2. At the same time, a bottom rod 31 is fixedly disposed horizontally at the lower end of the outer wall of the mounting plate 3. A tray 4 is horizontally placed on the upper surface of the bottom rod 31. The tray 4 is specifically disc-shaped, and multiple ventilation holes 41 are evenly distributed from the bottom end surface of the inner wall of the tray 4 to the bottom end surface. Subsequently, an arc-shaped support block 32 is disposed at the front and rear sides of the upper end of the outer wall of the mounting plate 3. The outer surface of the support block 32 is mutually fitted with the outer wall surface of the tray 4.

[0025] In the above structure, the installation part 2 and the installation plate 3 enable the trays 4 used during sterilization to be placed on the installation plate 3. After these trays 4 are placed, the user inserts the installation part 2 into the corresponding sterilization bucket, and then these trays 4 can be quickly arranged in the sterilization bucket to await subsequent disinfection operations.

[0026] Furthermore, to facilitate quick removal of the tray 4, the mounting part 2 can be designed as a semi-circular plate structure. This design allows the user to quickly remove the mounting part 2 from the mounting plate 3 using pliers or manually after it has been removed from the sterilization chamber.

[0027] Furthermore, to increase the placement stability of the mounting part 2, an extension part 21 is provided at the lower end of the mounting part 2. The extension part 21 is integrally formed with the mounting part 2, and a ring structure can be formed between the extension part 21 and the mounting part 2. This design allows the mounting part 2 to be placed stably on the table using the ring after it is removed, thus maintaining its stability when the tray 4 is installed later.

[0028] Furthermore, to facilitate the sterilization of the materials in the tray 4, the size of the vent hole 41 is designed to ensure sufficient hot air circulation while preventing small materials from leaking out. During use, the hot air in the sterilization chamber can pass through the materials from the bottom, thus achieving all-round sterilization. Therefore, the design of the vent hole 41 allows the bottom of the tray 4 to be hollowed out, which facilitates the circulation of hot air at the bottom of the materials. In addition, since the material tray 4 has baffles 36 of a certain height around it, it can prevent the materials from slipping.

[0029] Furthermore, to facilitate quick removal of the mounting part 2 and the tray 4, both the mounting part 2 and the tray 4 are provided with corresponding handles 42 along the upper part of their inner walls, allowing users to quickly pull them out during use.

[0030] In this embodiment, a mounting block 33 is provided on the lower left side of the base rod 31. A support rod 34 is inclined and hinged below the mounting block 33. A tension spring 35 is provided between the top middle of the support rod 34 and the lower surface of the base rod 31. At the same time, an arc-shaped baffle 36 is vertically provided on the lower left side of the tray 4, and the lower surface of the baffle 36 is connected to the support rod 34. This design allows the baffle 36 to abut against the lower left side of the tray 4 after it is unfolded, thus limiting the position of the tray 4 placed on the base rod 31. Secondly, since the support rod 34 is hinged, even when the tray 4 is moved to the left, a pushing force can be applied directly to the baffle 36. With the help of the pushing force, the support rod 34 will drive the baffle away from the tray 4, thus realizing the quick removal of the tray 4.

[0031] On the other hand, since the tray 4 is placed at the bottom rod 31, when the user needs to remove the tray 4, another method can be used, such as using tweezers to lift the tray 4 upwards, which can also achieve the removal process.

[0032] Furthermore, a limiting block 37 is provided on the lower surface of the bottom rod 31 along the left side of the support block 32. In use, the limiting block 37 can limit the rotation range of the support rod 34, so that the baffle 36 can be placed stably on the left side of the tray 4.

[0033] In this embodiment, the mounting part 2 has a vertical groove 5 extending from the outer wall to the inner wall. A positioning strip 51 is vertically and fixedly installed on one side of the inner wall of the groove 5. The positioning strip 51 has a plurality of positioning holes 52 evenly provided from top to bottom. Then, a slider 53 is slidably installed on the other side of the inside of the groove 5. One end of the slider 53 is connected to the mounting plate 3, and the other end extends toward the positioning strip 51. At the same time, a positioning pin 54 is slidably installed and passes through the slider 53, and the positioning pin 54 and the positioning hole 52 are arranged opposite to each other.

[0034] In the above structure, the sliding groove 5 and the slider 53 are designed so that when the installation height of the tray 4 needs to be changed, the user can move the slider 53 up and down by letting the mounting plate 3 drive it. After sliding to a suitable height, the user can insert the positioning pin 54 into the corresponding positioning hole 52, so as to limit and lock the displaced mounting plate 3.

[0035] Furthermore, a circular connecting groove 11 is provided at the top of the sterilization barrel body 1, and a bottle cap 12 is threaded onto the connecting groove 11.

[0036] The following is the specific workflow of this utility model: When sterilization is required, first, evenly place the material to be sterilized in tray 4, then place tray 4 onto the bottom rod 31 of mounting plate 3. Next, place sufficient water at the bottom of the sterilization chamber, and then push the entire mounting part 2 into the sterilization chamber. After pushing it in, initially tighten the bottle cap 12, leaving the exhaust channel open. Then, place the sterilization chamber into the sterilizer and heat until the water boils, keeping the exhaust channel open to release cold air. After the steam is steadily spraying out, close the exhaust channel and seal it completely. Continue heating until the pressure inside the chamber reaches the target sterilization temperature, such as 121℃. When the sterilizer is working, hot steam is generated inside the sterilization chamber and flows upward. At this time, the hot air can pass through the material from the bottom of tray 4, thereby achieving all-round sterilization.

[0037] After the materials in tray 4 have been sterilized, the user can use pliers or other tools to pull the installation part 2 out of the sterilization barrel. After pulling it out, the user can then remove the tray 4 from the installation part 2.

[0038] Furthermore, to meet the requirements of high-temperature and corrosion-resistant operating environments, the aforementioned components can be made of 316L stainless steel or high-temperature resistant polyether ether ketone (PEEK) material. Secondly, to facilitate the even entry of steam into the tray 4, the bottom rod 31 can adopt a perforated design, allowing steam to penetrate easily during use.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
