Embodiment 1

[0052] This embodiment describes an explosion-proof glass plate of a laboratory fume hood. The explosion-proof glass plate has better explosion-proof performance to ensure the safety of operators during the experiment.

[0053] The explosion-proof glass plate in this embodiment 1 is a transparent glass plate.

[0054] like figure 1 As shown, the explosion-proof glass plate includes a glass plate body 1 and a horizontal bar 2 connected to the lower part of the glass plate body. The material of the glass plate body 1 is toughened glass, and its thickness is 4-10 mm.

[0055] In this embodiment, the glass plate body 1 adopts a thickened tempered glass plate, which is beneficial to explosion-proof.

[0056] Among them, the explosion-proof ability of tempered glass is 3-5 times that of ordinary glass. When the tempered glass is damaged by external force, the fragments will become small particles with obtuse angles similar to honeycomb.

[0057] A through hole 3 for the arm to pa...

Embodiment 2

[0077] This embodiment 2 relates to an explosion-proof glass plate of a laboratory fume hood, except that the explosion-proof glass plate is different from the above-mentioned embodiment 1 in the following technical features, and other technical features can refer to the above-mentioned embodiment 1.

[0078] like figure 2 As shown, the explosion-proof glass plate of the laboratory fume hood mentioned in Embodiment 2 also includes a digital display temperature and humidity meter 6 with a time display function.

[0079] Wherein, the digital display temperature-hygrometer 6 is installed on the left side or the right side of the glass plate body 1 .

[0080] In this embodiment, the digital display temperature and humidity meter 6 can be installed in various ways, for example, by pasting connection, that is, the digital display temperature and humidity meter 6 is fixed on the glass plate body by strong glue, which will not be repeated here.

[0081] The digital display temperatu...

Embodiment 3

[0090] This embodiment 3 relates to an explosion-proof glass plate of a laboratory fume hood. The explosion-proof glass plate is different from the above-mentioned embodiment 2 except for the following technical features, and other technical features can refer to the above-mentioned embodiment 2.

[0091] like Figure 4 As shown, there are two through holes 3 in the present embodiment 3, and a through hole cover 4 is installed at each through hole 3, and the distance between the two through holes 3 is 40-50cm, preferably The value is 45cm.

[0092] In Embodiment 3, by designing two through holes 3, it is convenient to operate the instrument or pick and place small items through two arms during the experiment, and the operation comfort is higher.

[0093] Of course, the number of through holes 3 in this embodiment can also be reasonably set according to needs, which will not be described in detail here.

Abstract

The invention discloses an explosion-proof glass plate of a laboratory fume hood and the laboratory fume hood. The explosion-proof glass plate of the laboratory fume hood comprises a glass plate body; the glass plate body is a tempered glass plate or a polycarbonate endurance plate and is of an interlayer or curved-surface structure, so that the explosion-proof glass plate has good explosion-proof performance. In addition, the glass plate body is provided with at least one through hole allowing an arm to penetrate through and a through hole cover which is arranged at the through hole and mounted on the through hole in an opening and closing mode. When a laboratory operator carries out an experiment, the explosion-proof glass plate can be completely pulled down, and then operations such as taking and placing of small articles needed in the experiment process, instrument adjustment and the like can be carried out by the arm through the through hole. Taking and placing of the small articles or instrument adjustment is very convenient, ventilation and smoothness of experiment operations cannot be affected, meanwhile, the explosion-proof performance of the explosion-proof glass plate can be better exerted, and then the safety and health of the experiment operator in the experiment process are effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of laboratories, and in particular relates to an explosion-proof glass plate of a laboratory fume hood, and a laboratory fume hood with the explosion-proof glass plate. Background technique [0002] Air pollution is the most important environmental risk factor affecting health. The toxicity of air pollution acts on every organ of the human body, and when air pollution levels rise, it can lead to excessive mortality. [0003] In order to prevent laboratory workers from inhaling toxic, pathogenic or unknown toxic chemicals, the laboratory should have good ventilation, and the fume hood is an indispensable part of laboratory ventilation. [0004] The laboratory fume hoods in the prior art have considered the anti-virus function more, but neglected the anti-explosion effect. Explosions often occur during experiments, seriously endangering personal safety. [0005] To sum up the reason, the laboratory fume hood...
