技术领域technical field
本发明涉及粉尘检测设备技术领域，具体涉及一种粉尘浓度测量器及粉尘浓度测量套件。The invention relates to the technical field of dust detection equipment, in particular to a dust concentration measuring device and a dust concentration measuring kit.
背景技术Background technique
随着人们对空气质量的重视程度的不断增加，各种用于检测空气中粉尘浓度的测量仪器也不断增多。其中具有用来检测全尘浓度的测量仪器，也具有用来检测呼吸性粉尘浓度的测量仪器，在含有爆炸性气体的粉尘作业环境中，既需要测量全尘浓度又需要测量呼吸性粉尘浓度。现有技术中有如授权公告号为CN206470157U的中国实用新型专利公开一种具有气体浓度和粉尘浓度测量功能的测量仪，包括具有进气口与出气口的气体测量装置，还包括光源式粉尘测量探棒。气体检测装置包括第一壳体、设置于第一壳体内部的气体信息处理器、采样泵和设置于采样泵上的以对采样泵中的气体进行信号采集的气体传感器；光源式粉尘测量探棒包括第二壳体，第二壳体上设有手持部，第二壳体上具有测量通道，第二壳体内部于测量通道的相对两侧分别设置有光源发射器和光源接受器。光源式粉尘测量探棒的第二壳体上设有用于对光源发射器供电的并供粉尘信息处理器输出信号的粉尘信号接口，将粉尘信号结构与转接信号接口通过USB线连接，打开电源进行测量，就能够检测出粉尘的浓度，但是，这种检测方法仅能够检测全尘浓度，而不能够检测呼吸粉尘的浓度，功能单一；并且在检测全尘浓度时需要气体测量装置与粉尘测量探棒连接并同时工作，不方便携带。As people pay more and more attention to air quality, various measuring instruments for detecting dust concentration in the air are also increasing. Among them, there are measuring instruments for detecting the concentration of total dust, and there are also measuring instruments for detecting the concentration of respirable dust. In the dust working environment containing explosive gas, it is necessary to measure both the concentration of total dust and the concentration of respirable dust. In the prior art, for example, the Chinese utility model patent with the authorization announcement number CN206470157U discloses a measuring instrument with gas concentration and dust concentration measurement functions, including a gas measuring device with an air inlet and an air outlet, and a light source type dust measurement probe. Great. The gas detection device includes a first casing, a gas information processor disposed inside the first casing, a sampling pump, and a gas sensor disposed on the sampling pump to collect signals for the gas in the sampling pump; The rod includes a second casing, a hand-held part is arranged on the second casing, a measurement channel is arranged on the second casing, and a light source transmitter and a light source receiver are respectively arranged in the second casing on opposite sides of the measurement channel. The second shell of the light source type dust measurement probe is provided with a dust signal interface for supplying power to the light source transmitter and for the dust information processor to output signals. Connect the dust signal structure and the transfer signal interface through a USB cable, and turn on the power By measuring, the concentration of dust can be detected. However, this detection method can only detect the concentration of total dust, not the concentration of breathing dust, and has a single function; and when detecting the concentration of total dust, a gas measuring device and a dust measurement are required. The probes are connected and work at the same time, which is inconvenient to carry.
现有技术中也有全尘浓度和呼吸性粉尘浓度都能检测的两用测量仪，例如申请公布号为CN104749076A的中国发明专利申请公开的一种粉尘浓度及粘附力综合检测装置，包括呼吸性粉尘采样头、全尘采样头、滤膜、粉尘颗粒探测器、差压计、流量计、变频气泵、处理器及显示及控制面板，其既能够实现对全尘浓度的检测，也能够实现对呼吸性粉尘浓度的检测，但是，其将全尘浓度进行检测时所需的结构与呼吸性粉尘浓度进行检测时所需的结构集成在了一个箱体内，在检测全尘浓度时必须将检测呼吸性粉尘浓度的结构(例如呼吸性采样头及其连接管路)带上，在检测呼吸性粉尘浓度时必须将检测全尘浓度的结构(例如全尘采样头及其连接管路)带上，从而导致无论检测呼吸性粉尘浓度还是检测全尘浓度，都需要带上与检测无关的部件，使检测装置的结构比较复杂，重量较重，体积庞大，不易携带。In the prior art, there are also dual-purpose measuring instruments that can detect both total dust concentration and respirable dust concentration. Dust sampling head, dust sampling head, filter membrane, dust particle detector, differential pressure gauge, flow meter, variable frequency air pump, processor and display and control panel, which can not only detect the concentration of dust, but also realize the detection of dust concentration. The detection of respirable dust concentration, however, it integrates the structure required for the detection of total dust concentration and the structure required for the detection of respirable dust concentration into a box. The structure (such as the respiratory sampling head and its connecting pipeline) that detects the concentration of respiratory dust must be brought along with the structure for detecting the concentration of the total dust (such as the total dust sampling head and its connecting pipeline) when detecting the concentration of respiratory dust. As a result, no matter whether to detect the concentration of respirable dust or the concentration of total dust, it is necessary to bring components irrelevant to the detection, which makes the structure of the detection device more complicated, the weight is heavier, the volume is large, and it is not easy to carry.
