[0002] Air pollutants refer to those substances that are discharged into the atmosphere due to human activities or natural processes and have harmful effects on humans or the environment. According to their existence characteristics, they can be divided into two categories: aerosol pollutants and gaseous pollutants. In order to detect the ambient atmosphere, it is necessary to use a sampling device to sample the air containing pollutants;

[0003] When using existing pollutant sampling devices for air pollution control, an exhaust pipe is usually connected to the sampling device to extract air. The structure is relatively simple. When sampling gases at different heights, the exhaust pipe needs to be lengthened, which is more laborious and affects the collection efficiency. In addition, when sampling the air, a filter needs to be manually added at the air inlet to collect the filtered air. The adjustment back and forth is more cumbersome. At the same time, after long-term use, the air and the impurities contained therein are easy to remain in the trachea, which may affect the accuracy of subsequent collection. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a pollutant sampling device for air pollution control includes a mobile support platform 1, a gas extraction sampler body 2 is installed at the front position of the top of the mobile support platform 1, and a gas extraction component 3 is arranged at the top of the mobile support platform 1;

[0022] The vacuum assembly 3 includes a sampling hose 4 and a fixed rod 8. The fixed rod 8 is fixedly connected and installed on the rear end of the mobile support platform 1. A movable rod 9 is installed on the top of the fixed rod 8. A plurality of elastic fixing clips 10 are arranged at the front position of the outer circle of the movable rod 9. The sampling hose 4 is installed inside the plurality of elastic fixing clips 10. The rear end of the vacuum sampler body 2 is connected to the vacuum pipe. The bottom end of the sampling hose 4 is connected to the vacuum pipe. A plurality of sampling ports 5 are connected to the outer circle of the sampling hose 4 on one side. A plurality of air inlet filters 6 that are flush with the sampling ports 5 are connected to the outer circle of the sampling hose 4 on the other side. A solenoid valve 7 is arranged at the connection between the plurality of sampling ports 5, the air inlet filters 6 and the sampling hose 4.

[0023] In this embodiment, the fixed rod 8 and the movable rod 9 are slidably connected, and a locking knob 11 is provided at the connection between the movable rod 9 and the fixed rod 8. By loosening the locking knob 11, the movable rod 9 is released from being fixed. Thereafter, the movable rod 9 can be pulled out of the fixed rod 8 as needed to adjust the height of the sampling port 5, thereby facilitating the adjustment of the initial suction height of the sampling port 5 and the air inlet filter port 6.

[0024] In this embodiment, a filter box 12 is installed on one side of the top of the movable support platform 1. The filter box 12 is connected to the sampling hose 4 through a connecting pipe, and a cleaning solenoid valve 13 is provided at the connection. The filter box 12 is provided to filter the air, thereby facilitating the filtering and extraction of the air.

[0025] In this embodiment, the air outlet of the filter box 12 is connected to the air outlet pipe 18 and the cleaning pipe 15 through a three-way connector, and the end of the cleaning pipe 15 away from the air outlet of the vacuum sampler body 2 is connected to the sampling hose 4. By connecting the sampling bottle to the air outlet pipe 18, it is convenient to sample and collect air.

[0026] In this embodiment, a reversing valve 16 is provided at one end of the cleaning tube 15 close to the vacuum sampler body 2, and a one-way valve 17 is provided on the outer circle of the cleaning tube 15 and close to the connection with the sampling hose 4. The gas can be transported through the cleaning tube 15, which is convenient for blowing out impurities that may remain in the sampling hose 4, and for cleaning after use, to avoid the accumulation of a large amount of impurities affecting subsequent collection.

[0027] In this embodiment, an air intake solenoid valve 14 is provided at the connection between the exhaust pipe and the sampling hose 4, and an electromagnetic separation valve is provided on the outer circle of the sampling hose 4 and between the connecting pipe and the cleaning pipe 15, so as to separate the sampling hose 4 and facilitate air extraction and exhaust.

[0028] It should be noted that the utility model is a pollutant sampling device for air pollution control. When in use, the mobile support platform 1 can be moved to a suitable position as needed. When extracting filtered air, the air inlet solenoid valve 14 and the solenoid separation valve can be opened as needed, and the cleaning solenoid valve 13 and the reversing valve 16 can be closed. Then, according to the height of the sampling required, the solenoid valve 7 connected to the sampling port 5 at a suitable height can be started, so that the sampling port 5, the sampling hose 4 and the air extraction pipe of the air extraction sampler body 2 form a passage. Then, the air extraction sampler body 2 can be opened to extract air at a suitable height. At the same time, when extracting, the sampling bottle can be connected to the air outlet pipe 18 as needed to transport the air into the sampling bottle;

[0029] When sampling after filtering the air at a suitable height, the solenoid valve 7 connected to the air inlet filter port 6 can be opened according to the height of the air to be extracted, and the air inlet solenoid valve 14 and the electromagnetic separation valve need to be opened according to the above steps, and the cleaning solenoid valve 13 and the reversing valve 16 are closed, so that the air inlet filter port 6, the sampling hose 4 and the air extraction pipe of the air extraction sampler body 2 form a passage, so that the air can be filtered and extracted, which is convenient for subsequent detection and comparison with unfiltered air;

[0030] When extracting, the locking knob 11 can be loosened as needed to release the fixation of the movable rod 9, and then the movable rod 9 can be pulled out of the interior of the fixed rod 8 as needed. Since the sampling hose 4 is installed on the movable rod 9 through the elastic fixing clamp 10, the height of the sampling port 5 and the air inlet filter port 6 can be adjusted, thereby changing its initial suction height;

[0031] After long-term use, the air intake solenoid valve 14, the cleaning solenoid valve 13, and the reversing valve 16 can be opened as needed, and all the solenoid valves 7 can be opened at the same time, and the electromagnetic separation valve can be closed to form a passage through the connecting pipe, the cleaning pipe 15, and the sampling hose 4, so as to extract the filtered air and input the gas into the inlet and outlet pipes 18 and the cleaning pipe 15. After a period of time, the outlet pipe 18 can be blocked to allow all the gas to enter the cleaning pipe 15, thereby blowing out any impurities that may remain in the sampling hose 4, making it convenient to clean after use to avoid affecting subsequent collection.
