Description

Technical Field

[0001] The utility model relates to the technical field of samplers, and more particularly to an intelligent atmospheric sampler with automatic sample change. Background Art

[0002] An air sampler is an instrument or device used to collect atmospheric pollutants or polluted air. There are many types of air samplers. Based on the object being collected, they can be categorized as gas (including vapor) samplers and particulate matter samplers. Based on the location of use, they can be divided into environmental samplers, indoor samplers (such as those used in factory workshops), and pollution source samplers (such as chimney samplers). There are also special-purpose air samplers, such as those that collect both gas and particulate matter. These can collect sulfur dioxide and particulate matter, or hydrogen fluoride and particulate matter, in the atmosphere, facilitating the study of the relationship between sulfur or fluorine in gaseous and solid substances.

[0003] For example, the Chinese patent publication number CN220794753U proposes an intelligent integrated atmospheric sampler, which includes a collection box, a delivery pipe fixedly connected to the outer surface of the upper end of the collection box, a sampling port fixedly connected to the outer wall of the delivery pipe, the delivery pipe and the sampling port communicating with the interior of the collection box, a connection box provided on the outer surface of the lower end of the collection box, a support leg fixedly connected to the outer surface of the lower end of the connection box, and a lifting assembly provided on the outer surface of one side of the collection box connection box, the lifting assembly including a movable rod, a through hole, a drive motor, a movable cavity, an active rod, an active wheel, a driven wheel, a driven rod, a threaded rod, a threaded hole, and a limit block. The utility model is an intelligent integrated atmospheric sampler, which can be raised and lowered by the lifting assembly, and can sample gases at different heights as needed, detect the components in gases at different heights, and better obtain detection data. However, in actual use, when sampling at different locations, the filter membrane cannot be quickly replaced. To solve the above problem, we propose an intelligent atmospheric sampler with automatic sample replacement. Utility Model Content

At the same time, due to the characteristics of the rotary propulsion hydraulic cylinder 202 itself, it can drive the tray 2 to move up and down through the limit rod 2021, thereby facilitating the replacement of the filter membrane inside the filter membrane clamp 3.

[0027] Furthermore, the output end of the motor 14 is movably connected to the rotating shaft 401, and the side of the rotating shaft 401 is provided with a mounting seat 402, which is fixedly mounted on the upper surface of the workbench 1, and the side of the fixed cover 5 is adapted to the inner wall of the card slot 201, and the surface of the fixed cover 5 is fixedly connected to the swing arm 501, and the other end of the swing arm 501 extends to the inner wall of the mounting seat 402 and is fixedly connected to the side of the rotating shaft 401.

[0029] The working principle of the present invention is as follows: when in use, the filter membrane is first installed inside the filter membrane holder 3. During testing, the motor 4 drives the swing arm 501 to swing through the rotating shaft 401, so that the swing arm 501 pushes up the fixed cover 5, passes through the inner wall of the card slot 201, and lifts the filter membrane holder 3, so that the filter membrane holder 3 rotates 90 degrees upward with the rotating rod 302 as the axis, so that the filter membrane holder 3, the air inlet 102, and the fixed cover 5 are in the same horizontal position, and as the swing arm 501 continues to push, the connection between the filter membrane holder 3, the air inlet 102, and the fixed cover 5 becomes tighter, thereby improving the air tightness of the device. During the testing process, the air pump 6 will push the air The air is sucked through the interior of the filter membrane holder 3 through the air inlet 102. At this time, the dust, harmful substances or particulate matter in the atmosphere will remain on the filter membrane. After the sampling work is completed, the motor 14 will drive the swing arm 501 to swing through the rotating shaft 401, so that the swing arm 501 pulls down the fixed cover 5, and the filter membrane holder 3 rotates downward 90 degrees with the rotating rod 302 as the axis, so that the filter membrane holder 3 passes through the inner wall of the card slot 201 and the filter membrane holder 3 is repositioned to a horizontal position to prevent the collected dust or particulate matter from falling from the filter membrane. At the same time, the PLC controller 103 can detect the flow rate of the gas flowing inside the air inlet 102 through the gas flow sensor 603;

[0030] By providing multiple filter membrane clamps 3, during the detection process, when multiple detections are required, the rotating propulsion hydraulic cylinder 202 will drive the tray 2 to rotate, so that another filter membrane clamp 3 on the surface of the tray 2 can quickly replace the filter membrane clamp 3 after detection, thereby realizing the function of automatically replacing the filter membrane of the device, which is beneficial to improving the detection efficiency of the device. At the same time, due to the characteristics of the rotating propulsion hydraulic cylinder 202 itself, it can drive the tray 2 to move up and down through the limit rod 2021, thereby facilitating the replacement of the filter membrane inside the filter membrane clamp 3.
