Abstract
Description
Technical Field
[0001] This utility model belongs to the field of experimental equipment technology, specifically relating to an explosion protection device for experimental instruments. Background Technology
[0002] In the fields of chemistry and chemical engineering, laboratory instruments are frequently used for chemical experiments. Glass flasks, as a common type of laboratory instrument, are widely used in various types of chemical experiments.
[0003] During experiments, glass flasks are usually placed in fume hoods. When encountering closed reactions, prolonged heating, handling of explosive solvents, incorrect feeding sequence, or uneven heating of the reaction system, the internal pressure of the glass flask can easily increase dramatically, leading to an explosion.
[0004] When a glass flask explodes, although the fume hood panel can intercept some fragments, the glass fragments gain significant kinetic energy during the explosion and are easily scattered. Some fragments will still escape through the gaps in the fume hood, causing injury to laboratory personnel. In severe cases, glass fragments can also cause serious damage to the fume hood.

[0041] Example 1
[0042] Reference Figures 1 to 3As shown, this embodiment provides an explosion protection device for experimental instruments. The device includes a frame 1 and a cover 2. The frame 1 is rectangular and includes a first frame 11, a second frame 12, a plurality of fourth rods 13, and a plurality of fifth rods 14 arranged opposite to each other. The first frame 11 and the second frame 12 are arranged opposite to each other along a first direction. An opening 122 is formed on the second frame 12. The first frame 11 and the second frame 12 are connected by the plurality of fourth rods 13, and the fifth rods 14 are disposed between adjacent fourth rods 13. The cover 2 surrounds the first frame 11 and the second frame 12 and covers the first frame 11. An accommodating cavity for accommodating an experimental instrument 3 is formed inside the cover 2. A support portion for supporting the experimental instrument 3 is formed inside the cover 2 in a second direction. The experimental instrument 3 presses down on the support portion from the top, preventing the frame 1 and the cover 2 from overturning.
[0043] Reference Figure 11 As shown, in practical applications, experimental instruments 3 are generally placed inside fume hoods 4. Fume hoods 4 generally have an upper surface, a lower surface, a rear surface, a left surface, and a right surface. Therefore, the opening 122 on the second frame 12 needs to face the rear surface of the fume hood 4, the first frame 11 faces the experimental personnel, and the support part of the cover 2 contacts the lower surface inside the fume hood 4 to support the frame 1 and the cover 2.
[0044] Reference Figures 2 to 3 As shown, the first frame 11 of this embodiment includes four first rods 111 arranged along its circumference and two second rods 112 disposed between the four first rods 111. The four first rods 111 are connected end to end in sequence to form the first frame 11.
[0045] The connection points of two adjacent first rods 111 form four first intersection points 1111. The two ends of one second rod 112 are connected to two non-adjacent first intersection points 1111 respectively, and the two ends of the other second rod 112 are connected to the other two non-adjacent first intersection points 1111 respectively, forming an X-shaped intersection structure, which improves the structural strength of the first frame 11 and enables it to withstand stronger impact forces.
[0046] In addition, the cross structure formed by the two second rods 112 can also enhance the contact area between the first frame 11 and the cover 2, improve the connection strength between the first frame 11 and the cover 2, and improve the interception efficiency of the cover 2 for the fragments generated by the explosion of the experimental instrument 3.
[0047] Reference Figures 2 to 3 As shown, the second frame 12 of this embodiment includes four third rods 121, which are connected end to end to form the second frame 12, and the area between the four third rods 121 forms an opening 122.
[0048] The connection points of two adjacent third rods 121 form four second intersection points 1211, which correspond one-to-one with the four first intersection points 1111. Four fourth rods 13 are provided, all of which are parallel to the first direction. The first end of each fourth rod 13 is connected to one of the first intersection points 1111 of the first frame 11, and the second end is connected to one of the second intersection points 1211 of the second frame 12.
[0049] Reference Figures 2 to 3 As shown, in the four fourth rods 13, an installation area is formed between every two adjacent fourth rods 13, forming a total of four installation areas. In this embodiment, eight fifth rods 14 are provided, and these eight fifth rods 14 are combined in pairs to form four groups. Each group of fifth rods 14 is correspondingly positioned within one of the four installation areas. The two fifth rods 14 in each group form an X-shaped intersecting structure, with the two ends of each fifth rod 14 connected to the first intersection point 1111 and the second intersection point 1211, respectively.
[0050] Reference Figure 1 and Figure 2 As shown, four first rods 111 form a rectangular first skeleton 11, and four second rods 112 form a rectangular second skeleton 12. On a plane perpendicular to the first direction, the vertical projections of the first skeleton 11 and the second skeleton 12 are both rectangles, and the two vertical projections substantially overlap.
[0051] In this embodiment, the first rod 111, the second rod 112, the third rod 121, the fourth rod 13, and the fifth rod 14 can be made of steel bars. The diameter of the steel bars is not less than 0.8 mm, and can be specifically set to 0.8 mm, 1 mm, 1.2 mm, or 1.5 mm. The length of the steel bars is not less than 300 mm, and can be specifically set to 300 mm, 400 mm, 500 mm, or 600 mm. The two steel bars to be connected are connected by welding.
[0052] Reference Figure 1 As shown, the cover 2 is made of metal mesh with a grid structure. The shape of each individual grid is rectangular, and the length and width of the rectangle are not less than 4mm and not more than 6mm.
[0053] In other embodiments, the individual grid described above may also be set to a regular shape other than a rectangle, such as a circle, a regular pentagon, or a regular hexagon. Alternatively, the individual grid described above may also be set to an irregular shape.
[0054] Example 2
[0055] Reference Figure 4 and Figure 5As shown, this embodiment provides an explosion protection device for experimental instruments. The difference between this embodiment and Embodiment 1 is that only one fifth rod 14 is provided between two adjacent fourth rods 13.
[0056] Example 3
[0057] Reference Figure 6 and Figure 7 As shown, this embodiment provides an explosion protection device for experimental instruments. One of the differences between this embodiment and Embodiment 1 is that the two ends of the second rod 112 in this embodiment are connected to two oppositely arranged first rods 111, specifically connected to the first connection point 1112 on the first rod 111. The first connection point 1112 is located at the center of the first rod 111.
[0058] In other embodiments, the position of the first connection point 1112 can also be adjusted to ensure that the first connection point 1112 is located between the end faces on both sides of the first rod 111.
[0059] The second difference between this embodiment and embodiment one is that this embodiment sets up eight fourth rods 13. The positions and connection relationships of four of the fourth rods 13 are the same as those of the four fourth rods 13 in embodiment one. In the other four fourth rods 13, the first end of each fourth rod 13 is connected to the first connection point 1112 of the first rod 111, and the second end is connected to the second connection point 1212 of the third rod 121.
[0060] The third difference between this embodiment and embodiment one is that the fifth rod 14 in this embodiment is only connected to the fourth rod 13, and the four fifth rods 14 form a rectangular structure.
[0061] Example 4
[0062] Reference Figure 8 and Figure 9 As shown, this embodiment provides an explosion protection device for experimental instruments. One of the differences between this embodiment and Embodiment 1 is that the first frame 11 of this embodiment includes four second rods 112, and each second rod 112 is connected to a first connection point 1112 on two adjacent first rods 111.
[0063] The second difference between this embodiment and embodiment one is that this embodiment sets up sixteen fifth rods 14. The sixteen fifth rods 14 are divided into four groups of four. The fifth rods 14 in each group are connected end to end to form a rectangular structure. The rectangular structure has four intersection points. The first intersection point connects to the first connection point 1112, the second intersection point connects to the second connection point 1212, the third intersection point connects to a fourth rod 13, and the fourth intersection point connects to another fourth rod 13.
[0064] Example 5
[0065] Reference Figure 10 As shown, this embodiment provides an explosion protection device for experimental instruments. The difference between this embodiment and Embodiment 1 is that the cover 2 of this embodiment has a window 21. The window 21 is arranged along the second direction and located above the support, so that the experimenter can add reactants into the experimental instrument 3 through the window 21. Alternatively, the experimenter can also insert a stirring rod into the experimental instrument 3 through the window 21 to stir the reactants inside the experimental instrument 3.
[0066] Those skilled in the art will understand that the structure of the skeleton 1 in all the above embodiments is a preferred example. In other embodiments, the shape of the skeleton 1 can also be set as a cube of other shapes, and the shapes of the first skeleton 11 and the second skeleton 12 are constructed as regular polygons such as triangles, pentagons, and hexagons. After the shapes of the first skeleton 11 and the second skeleton 12 are changed, the number and connection relationship of the first rod 111, the second rod 112, the third rod 121, the fourth rod 13 and the fifth rod 14, as well as the coverage position of the cover 2, will also be adaptively adjusted to intercept the fragments generated by the explosion of the experimental instrument 3. Therefore, the alternative solutions obtained by adjusting the shape and number of the skeleton 1 and the cover 2 of this utility model also fall within the protection scope of this utility model.
[0067] In addition, the experimental instrument 2 in all the above embodiments can be a glass flask, or other glass or non-glass instruments.
[0068] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0069] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
