Problems solved by technology
[0002] The preparation of hydrogen sulfide in the laboratory generally adopts Zipp generator. Since the density of hydrogen sulfide is greater than the mass of air, it is generally collected by upward exhaust air collection method, but sodium hydroxide solution should be used to absorb hydrogen sulfide to prevent human poisoning Pollution of the air, if the test is slightly negligent, hydrogen sulfide gas will leak, and when the density of hydrogen sulfide in the air is greater than a certain level, it will cause poisoning

Embodiment Construction
[0017] All features disclosed in this specification, or steps in all methods or processes disclosed, can be combined in any way, except for mutually exclusive features and or steps.
[0018] Combine below Figure 1-5 The present invention is described in detail, and for convenience of description, the orientations mentioned below are now stipulated as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.
[0019] A kind of anti-leakage device for the experiment of producing hydrogen sulfide gas in a laboratory of the device of the present invention comprises a test bench 10 and an experiment tank 11 which is located in the test bench 10 with an upward opening and an opening forward. Lifting device 901, the lifting device 901 includes a clamping groove 41 located in the rear end wall of the test tank 11 and connected to the test tank 11, a slider 39 is slidably connected in the clamping groove 41, and the sli...

The invention discloses an anti-leakage device for an experiment for preparing hydrogen sulfide gas in a laboratory. The anti-leakage device comprises an experiment table and an experiment tank located in the experiment table body and provided with an upward opening and a forward opening. A lifting device is arranged in the experiment table; the lifting device comprises a clamping tank which is positioned in the rear end wall of the experiment tank and is communicated with the experiment tank; a sliding block is connected into the clamping tank in a sliding manner; a first sliding tank with aforward opening is formed in the sliding block; and a first T-shaped block is connected into the first sliding tank in a sliding manner. The device can automatically adjust the height of a hydrochloric acid storage shell according to the requirements of people, and meanwhile, when the device works, gas on the workbench can be continuously detected. Due to the fact that the density of hydrogen sulfide is large than that of air, when the density of poisonous gas in the experiment tank is larger than a certain value, the device can automatically seal the experiment tank and treat leaked gas, so that health of people is not threatened.
Description
technical field [0001] The invention relates to the technical field of working test benches, in particular to a leak-proof device for the experiment of producing hydrogen sulfide gas in a laboratory. Background technique [0002] The preparation of hydrogen sulfide in the laboratory generally adopts Zipp generator. Since the density of hydrogen sulfide is greater than the mass of air, it is generally collected by upward exhaust air collection method, but sodium hydroxide solution should be used to absorb hydrogen sulfide to prevent human poisoning To pollute the air, if the test is slightly negligent, hydrogen sulfide gas will leak. When the density of hydrogen sulfide in the air is greater than a certain level, it will cause poisoning. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned technologies, the present invention proposes a leak-proof device for the experiment of producing hydrogen sulfide gas in a laboratory, which can overcome t...
