Detailed Implementation

[0022] The endotoxin removal device of the present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0023] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0024] like Figure 1 As shown in the figure, this utility model embodiment proposes an endotoxin removal device, including a tank 1 and an endotoxin removal component 2. Specifically, the endotoxin removal component 2 is installed inside the tank 1 and is used to remove endotoxins from the pure steam formed by heating and evaporating raw water. After removing endotoxins, the quality of the pure steam is guaranteed, reducing the quality risk caused by endotoxins.

[0025] In one specific embodiment, such as Figures 2-4 As shown, the endotoxin removal component includes a first outer shell 21, a second outer shell 22, and a filter screen 23. Specifically, the first outer shell 21 and the corresponding ends of the second outer shell 22 are connected to form a frame structure; the filter screen 23 is installed on both sides of the frame structure, forming a hollow frame structure; the frame structure is filled with wire mesh. The connection between the corresponding ends of the first outer shell 21 and the second outer shell 22 cleverly forms a stable frame structure. This not only enhances the stability of the entire component but also provides support for the installation of the filter screen 23. The filter screen 23 is installed on both sides of the frame structure, forming a hollow frame structure together with the frame structure. This allows the filter screen 23 to be evenly distributed throughout the component, thereby improving filtration efficiency and uniformity. The wire mesh filling the hollow frame structure can remove endotoxins. In addition, the wire mesh filling not only increases the filtration area and improves filtration efficiency, but the physical properties of the wire mesh can also effectively capture and remove endotoxins. This embodiment improves the endotoxin removal efficiency and the purity of pure steam by combining the frame structure and filter screen 23, as well as filling the internal wire mesh.

[0026] In this embodiment, the mesh size ranges from 80 to 120 mesh. For example, the mesh size can be 80, 90, 100, 110, or 120 mesh. Since a higher mesh size generally results in better endotoxin removal but poorer ventilation, the mesh size can be set according to actual needs, including but not limited to the range described in this embodiment, with 100 mesh being preferred. Choosing a suitable mesh size (e.g., 100 mesh) ensures good ventilation while maintaining effective endotoxin removal, guaranteeing smooth steam flow. Furthermore, by setting the mesh size to a range of 80 to 120 mesh, users can find an optimal balance between removal efficiency and ventilation, thereby achieving highly efficient endotoxin removal.

[0027] In one embodiment, the endotoxin removal assembly further includes a connecting plate 24 disposed on the frame structure; both ends of the connecting plate 24 are connected to the first outer shell 21 and the second outer shell 22, respectively. The connecting plate 24 tightly connects the first outer shell 21 and the second outer shell 22, enhancing the structural stability of the entire assembly.

[0028] The connecting plate 24 is perpendicular to the connecting plate 24. This helps to distribute stress evenly and improve the stability of the connection.

[0029] Furthermore, there are multiple connecting plates 24, and these connecting plates 24 are evenly distributed on the frame structure. This makes the stress distribution of the entire component more uniform, further improving the stability and durability of the structure.

[0030] In a preferred embodiment, the first outer casing 21 and the second outer casing 22 are provided with a plurality of openings 25, and a filter screen 26 is provided within each opening 25. This is intended to ensure effective removal of endotoxins while increasing ventilation. Therefore, this embodiment ensures that pure steam can pass through smoothly while ensuring that the removal effect of endotoxins is not affected. This allows the device to maintain high-efficiency filtration performance when processing large amounts of pure steam, while avoiding efficiency reduction due to poor ventilation. In addition, the design of multiple openings 25 increases the ventilation area, thereby increasing the ventilation volume and ensuring smooth flow of pure steam.

[0031] Furthermore, this embodiment also includes a partition 3. Specifically, the partition 3 is connected to the endotoxin removal component to form a partition plate; the partition plate is installed inside the tank 1 along a direction perpendicular to the pure steam flow, dividing the interior of the tank 1 into a first space 4 and a second space 5; the raw water is located in the second space 5, and the pure steam formed by heating and evaporating the raw water enters the first space 4 through the endotoxin removal component 2. Subsequently, the pure steam can enter a designated location through the exhaust channel 6 of the first space 4.

[0032] In this embodiment, the outer wall of the endotoxin removal component away from the partition 3 is fitted with the inner wall of the tank 1, which can reduce the leakage of pure steam.

[0033] In a preferred embodiment, both the first outer shell 21 and the endotoxin removal component have a semi-circular structure. This helps improve space utilization and facilitates installation and maintenance. Those skilled in the art will understand that, to achieve the same effect, the shapes of the first outer shell 21 and the endotoxin removal component can be set according to actual needs, for example, according to the shape of the tank 1.

[0034] In a preferred embodiment, the thickness of the endotoxin removal component ranges from 13 to 17 cm. For example, the thickness of the endotoxin removal component can be 13 cm, 14 cm, 15 cm, 16 cm, and 17 cm. Since a thicker endotoxin removal component results in better endotoxin removal but poorer ventilation, the thickness of the endotoxin removal component can be set according to actual needs, including but not limited to the thickness range described in this embodiment, with 15 cm being the preferred thickness.

[0035] In this embodiment, the size of the device can be set according to actual needs.

[0036] In this embodiment, after the raw water in the second space 5 is heated, the pure steam formed by evaporation passes through the wire mesh in the endotoxin removal component to remove endotoxins (since the partition 3 is a closed plate, the pure steam cannot pass through the partition 3, but can only enter the first space 4 through the endotoxin removal component), and then enters the first space 4, and enters the next process through the exhaust channel 6.

[0037] In summary, the endotoxin removal device proposed in this utility model has the following advantages:

[0038] The device employs a tank and an endotoxin removal assembly. The endotoxin removal assembly, installed within the tank, removes endotoxins from the pure steam generated by heating and evaporating raw water. The endotoxin removal assembly includes a first outer shell, a second outer shell, and a filter screen. The corresponding ends of the first and second outer shells are connected to form a frame structure. The filter screen is installed on both sides of the frame structure, forming a hollow frame structure. The interior of the frame structure is filled with wire mesh. This device can remove endotoxins from pure steam, improving the purity of the pure steam.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
