[0028] Reference Figure 1 As shown, the utility model provides a technical solution: an atmosphere and particulate matter separation sampling device, comprising a separation sampler 1, a mounting tube 2 is threaded through the upper surface of the separation sampler 1, the upper end of the mounting tube 2 is connected to a sampling box 3, a replacement device 4 is provided on the surface of the sampling box 3, and a winding structure 5 is provided on the side wall of the square tube 401.

[0029] The specific configuration and function of the replacement device 4 and the winding structure 5 will be described in detail below.

[0030] Reference Figures 1-3As shown, in this embodiment, the replacement device 4 includes a square tube 401 fixedly mounted inside the sampling box 3. Two mounting bars 402 are fixedly mounted on the side walls of the square tube 401. Bolts 403 are threadedly connected to the interior of each mounting bar 402. A filter cloth roll 404 is sleeved on the outside of the two bolts 403. The filter cloth roll 404 is placed between the two bolts 403. The bolts 403 on the inner side of the mounting bar 402 are rotated to insert the bolts 403 into the middle of the filter cloth roll 404. This completes the initial installation of the filter cloth roll 404. A circular plate 405 is fixedly mounted on the side walls of the bolts 403. By rotating the bolts 403, the position of the circular plate 405 can be adjusted to align the filter cloth roll 404 with the entrance of the square tube 401. Two rectangular blocks 408 are fixedly mounted on the surface of the square tube 401. Two slide bars 409 are slidably connected to the interior of each block 408. A pressure strip 406 is fixedly mounted on the other end of each slide bar 409. A drive rod 410 is threadedly connected to the interior of each block 408, and the drive rod 410 is rotatably connected to the interior of the pressure strip 406. Rotating the drive rod 410 within the rectangular block 408 actuates the pressure strip 406, thereby securing the filter cloth after replacement. A sealing gasket 407 is glued to the surface of the pressure strip 406. The pressure strip 406 drives the sealing gasket 407 to securely secure the filter cloth, preventing air leakage during atmospheric and particulate matter sampling.

[0031] Reference Figures 1-2 and Figure 4 As shown, the winding structure 5 specifically includes a positioning bar 51 fixedly connected to the side wall of the square tube 401. A rotating rod 52 is rotatably connected to the interior of the positioning bar 51, and a rotating block 55 is fixedly connected to the end of the rotating rod 52. Rotating the rotating block 55 drives the rotating rod 52 to rotate within the positioning bar 51, enabling the filter cloth to be quickly wound up after use. A sliding frame 53 is slidably connected to the interior of the rotating rod 52, and a pressure rod 54 is fixedly connected to the end of the sliding frame 53. The sliding frame 53 is subjected to the elastic force of a spring 56 on the rotating rod 52, driving the pressure rod 54 to closely adhere to the surface of the filter cloth. A spring 56 is fixedly installed between the sliding frame 53 and the rotating rod 52. The sliding frame 53 drives the pressure rod 54 to closely adhere to the surface of the filter cloth, preventing the filter cloth from becoming loose during winding.

[0032] Working principle: place the filter cloth roll 404 between the two bolts 403, rotate the bolt 403 inside the installation bar 402, and insert the bolt 403 into the middle of the filter cloth roll 404. At this time, the preliminary installation of the filter cloth roll 404 can be achieved. By rotating the bolt 403, the position of the circular plate 405 can be adjusted, and the filter cloth roll 404 can be aligned with the entrance position of the square tube 401, thereby improving the efficiency of subsequent replacement of the filter cloth on the filter cloth roll 404 by inserting it into the inside of the square tube 401. When the filter cloth needs to be replaced, the filter cloth can be replaced by pulling the filter cloth roll 404 inside the square tube 401, thereby effectively improving the filter cloth To improve the efficiency of replacement, after replacing the filter cloth, rotate the driving rod 410 inside the rectangular block 408, and then the pressure strip 406 can be driven to fix the filter cloth after replacement. The pressure strip 406 will drive the sealing gasket 407 to tightly install the filter cloth, avoiding air leakage in the device during the sampling of atmosphere and particulate matter, and improving the stability of atmosphere sampling. By setting up the replacement device 4, it is convenient to quickly replace the filter cloth without disassembling the sampling box 3, avoiding the tedious process of traditional disassembly of the sampling box 3 to replace the filter cloth, and to a certain extent improving the efficiency of replacing the filter cloth.

[0033] After replacing the old discarded filter cloth, the pressure rod 54 is pulled to put the extra used filter cloth between the pressure rod 54 and the rotating rod 52 on the outside of the rotating rod 52, and the rotating block 55 is rotated. The rotating block 55 will drive the rotating rod 52 to rotate inside the positioning bar 51, so that the used filter cloth can be quickly rolled up. In the process of rolling up the filter cloth, the sliding frame 53 will be affected by the elastic force of the spring 56 on the rotating rod 52 to drive the pressure rod 54 to fit closely to the surface of the filter cloth, avoiding the loosening of the filter cloth during the rolling process and improving the stability of the rolling of multiple filter cloths. By setting the rolling structure 5, the flexible rolling up of the used filter cloth is facilitated, and the phenomenon of frequent cutting of the filter cloth and inconvenience in handling the used filter cloth is avoided, thereby improving the efficiency of handling the used filter cloth to a certain extent.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
