Technical Field

[0001] The utility model relates to the technical field of waste gas collection, in particular to a waste gas collection device. Background Art

[0002] Waste gas refers to toxic and harmful gases emitted by humans in the process of production and life. There are many types of pollutants in waste gas, and their physical and chemical properties are very complex, and their toxicity varies. Waste gas emitted from fuel combustion contains sulfur dioxide, nitrogen oxides (NOx), hydrocarbons, etc.; due to different raw materials and processes used in industrial production, various harmful gases and solid wastes are emitted, containing various components such as heavy metals, salts, and radioactive substances; the exhaust gas emitted by automobiles contains hydrocarbons such as lead, benzene and phenol.

[0003] Waste gas is continuously generated during industrial production, and direct emission of waste gas will cause great harm to human living environment and health. Therefore, the waste gas needs to be purified before being discharged. In order to ensure the emission standards, the waste gas needs to be inspected and treated regularly. In order to reduce the harm to the inspectors, it is usually chosen to take samples and send them to the detector for testing. The slow collection process will also cause the collectors to be in the waste gas range for a long time. For this reason, we propose a waste gas collection device. Utility Model Content

During use, the first sealing gasket 3 can be used to ensure the sealing of the movable sleeve 2, and the leakage of the inner cavity air of the exhaust sleeve 1 and the external air of the movable sleeve 2 during the activity of the movable sleeve 2 can be prevented The interaction affects the air tightness. The left and right sides of the movable sleeve 2 are respectively fixedly connected with the first sealing pad 3. The rear of the air extraction sleeve 1 is fixedly installed with a ventilation pipe 4 located inside the movable sleeve 2. The ventilation pipe 4 extends forward and backward to the inside and outside of the air extraction sleeve 1 respectively. The ventilation pipe 4 can ensure the smooth pulling of the movable sleeve 2. By pulling the movable sleeve 2 backward, the movable sleeve 2 and the first sealing pad 3 are pulled backward, thereby increasing the space in the inner cavity of the air extraction sleeve 1 and the fixed sleeve 6, and the negative pressure in the inner cavity of the air extraction sleeve 1 and the fixed sleeve 6 is used to quickly exhaust the waste gas bag. Rapid air suction can effectively improve the speed and efficiency of exhaust gas collection and reduce collection. The inner cavity of the exhaust sleeve 1 is fixedly sleeved with a connecting metal sheet 5 near the bottom position, and the inner part of the fixing sleeve 6 is fixedly sleeved with an electromagnetic ring 8 near the top. The fixing sleeve 6 is installed below the exhaust sleeve 1 so that the second sealing gasket 7 is sleeved on the outside of the bottom end of the exhaust sleeve 1. After the second sealing gasket 7 covers the outside of the exhaust sleeve 1 and the fixing sleeve 6, the electromagnetic ring 8 is controlled to start, and the electromagnetic ring 8 is used to adsorb the connecting metal sheet 5 to stably fix the exhaust sleeve 1 and the fixing sleeve 6.

[0022] See also Figure 5 The utility model provides a technical solution: the front wall of the exhaust sleeve 1 is fixedly sleeved with a connecting gasket 9, and the front wall of the exhaust sleeve 1 is fixedly installed with a fixed clamping block 10, the fixed clamping block 10 and the movable clamping block 14 are located in front of the connecting gasket 9, and a friction pattern is provided between the fixed clamping block 10 and the movable clamping block 14.
