Description

Technical Field

[0001] The utility model relates to the technical field of sampling and detection, in particular to a particle sampling and detection device. Background Art

[0002] Particle sampling and detection is mainly used to monitor and evaluate the concentration and composition of suspended particulate matter in the atmosphere. Through the collection and analysis of the sampler, the mass concentration data of particulate matter can be accurately obtained and its impact on the environment and human health can be evaluated. These detection data are of great significance for formulating environmental protection policies and measures, safeguarding public health and promoting sustainable development.

[0003] The utility model with the authorization announcement number CN216349828U provides a sampling device for atmospheric particulate matter detection, which belongs to the technical field of "sampling detection". The protected claim is: "It includes a sampling box, a sampling mechanism is arranged inside the sampling box, a partition is installed on the right side of the inside of the sampling box, a baffle is installed on the right side of the partition, the end of the baffle away from the partition is connected to the inner wall of the sampling box, and placement plates are installed on the front and rear sides of the baffle, and the side of the placement plate away from the baffle is connected to the inner wall of the sampling box. A plurality of U-shaped plates are installed on the upper part of the placement plate, and a filter plate is installed between two corresponding U-shaped plates. The sampling mechanism includes an air pump, a sampling tube, and a connecting tube. The air pump is installed on the left side of the bottom end of the sampling box. When the utility model is in use, when it is necessary to sample the atmosphere in different areas, there is no need to frequently replace the filter plate, and multiple sampling can be performed. After the sampling is completed, the filter plate is easy to replace, which greatly improves the practicality of the device."

[0004] In this device, although the filter plate can be replaced, it needs to be pulled out for replacement, and it is not easy to clean it immediately to ensure that the sampler continues to operate in an efficient state, thereby maintaining a high sampling efficiency. For this reason, we propose a particulate matter sampling and detection device. Utility Model Content

[0026] During specific implementation, the first motor 201 is started, and the first motor 201 drives the first rotating rod 202 to rotate. The rotation of the first rotating rod 202 drives the rotating disk 203 to rotate. The rotation of the rotating disk 203 drives the four filter plates 204 to rotate in turn. The four filter plates 204 rotate between the first detection tube 3 and the second detection tube 4 in turn, which is convenient for timely replacement. When a filter plate 204 is used up, the rotating disk 203 can be rotated to replace the next clean filter plate 204, and the two second motors 206 are started. The two second motors 206 drive the second rotating rod 207 to rotate, thereby driving the two brush plates 208 to rotate. The rotation of the two brush plates 208 can clean the upper and lower sides of the filter plate 204. At the same time, the fan 8 is started to blow off the remaining dust, etc., and then drop it into the waste box 7 for cleaning after it is full. In summary, the device is convenient for timely replacement of the filter plate 204, and can be cleaned immediately to ensure that the sampling continues to operate in an efficient state, thereby maintaining a high sampling efficiency.

[0027] Furthermore, a first detection tube 3 is fixedly connected to the box body 1, and the bottom end of the first detection tube 3 extends into the box body 1. A second detection tube 4 is fixedly connected inside the box body 1. The filter plate 204 is movably inserted between the first detection tube 3 and the second detection tube 4. The sampled sample is input through the first detection tube 3, and then input into the second detection tube 4 after being filtered by the filter plate 204. There is a gap between the filter plate 204 and the first detection tube 3 and the second detection tube 4, but the gap does not affect the entry of the sample. The sample leaking from the gap will fall into the waste box 7 and be cleaned after it is full.

[0028] Furthermore, the bottom end of the second detection tube 4 extends out of the box body 1 and is fixedly connected to a processor 5, in which a sample tube 6 is movably inserted. The sample is input into the processor 5 through the second detection tube 4 for processing. The processor 5 is prior art and will not be described in detail.

When a filter plate 204 is used up, the turntable 203 can be rotated to replace the next clean filter plate 204, and the two second motors 206 are started. The two second motors 206 drive the second rotating rod 207 to rotate, thereby driving the two brush plates 208 to rotate. The rotation of the two brush plates 208 can clean the upper and lower sides of the filter plate 204. At the same time, the fan 8 is started to blow off the remaining dust, which then falls into the waste box 7 and is cleaned after it is full.
