Description

Technical Field

[0001] The utility model relates to the technical field of laboratory gas emission, in particular to a gas monitoring emission pipe group for an asphalt laboratory. Background Art

[0002] Asphalt test laboratory is an important place for asphalt material research and testing. During the heating, stirring and testing of asphalt, a large amount of harmful gases and pollutants will be generated, such as asphalt smoke, sulfur dioxide, nitrogen oxides, etc. These pollutants will not only pollute the internal environment of the laboratory, but may also escape into the atmosphere through the emission pipes, causing harm to the surrounding environment and human health. Therefore, it is particularly important to monitor and control the emissions of gases in asphalt test laboratories.

[0003] In asphalt gas emissions, the gas is usually transmitted through pipelines. The connection between the pipeline and the monitor is usually made by operators using threaded connections. This traditional connection method is prone to asphalt gas leakage, which can cause harmful gases to harm the human body.

[0004] In view of this, we propose a gas monitoring emission pipe set for an asphalt test laboratory. Utility Model Content

[0016] 1. In order to improve the working efficiency of the asphalt test laboratory gas monitoring emission pipe group, a clamping mechanism is set to cooperate with the movement of the round hoop, telescopic machine, telescopic rod, protrusion, movable rod, rotating block and rubber wheel. When the telescopic machine is started, it will drive the telescopic rod to move, and the movement of the telescopic rod will cause the protrusion to drive the round hoop to rotate.
