Technical Field
[0001] The utility model relates to the technical field of dust samplers, and more specifically, to an automatic flow calibration detection device. Background Art
[0002] A dust sampler is an instrument used to measure the concentration of floating dust in ambient air and is widely used in fields such as industry, mining, and environmental monitoring. Dust samplers all possess high precision and stability and can meet the dust sampling requirements under different environments and conditions.
[0003] In the current market, existing dust samplers mainly rely on the vacuum device inside them to powerfully drive and introduce external air into the sampler. However, it should be noted that such common dust samplers have certain drawbacks. Their flow rate is easily disturbed by the blockage of large particulate dust, and it is also affected by various factors in the external environment such as temperature, humidity, and air pressure. The combined effect of these factors has a relatively significant adverse impact on the quality and accuracy of detection. For example, in some environments with large and high-concentration dust particles, the blockage of large particulate dust may cause the flow rate of the sampler to drop sharply, making it impossible to accurately collect representative samples; when the external environmental temperature is too high or too low, the performance of the internal components of the sampler may change, thereby affecting the stability and accuracy of the flow rate, and ultimately causing deviations in the detection results.
[0004] Therefore, an automatic flow calibration detection device is proposed to solve the problem that the induced air flow is affected by large particulate dust and the detection accuracy is reduced. Summary of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an automatic flow calibration detection device that improves the detection efficiency and accuracy, improves the energy use efficiency, and reduces manual intervention.

A suction fan is arranged at the bottom end of the flow control component. A flow detection component is arranged on one side of the suction fan. The dust detection component includes a dust detection housing. A dust detection air outlet is arranged at the bottom of the dust detection housing. A circular dust inlet is opened at the top of the dust detection housing. A lighting lamp is arranged on one side of the dust detection housing. A refraction extinction is arranged on the side opposite to the lighting lamp. A detection mounting table is arranged on one side of the dust detection housing.
[0008] By adopting the above technical solution, the dust air inlet introduces the preliminarily light-filtered air into the interior of the dust detection housing. The light source is emitted by the lighting lamp, and the light source is refracted and extinguished when it enters. The refraction and extinction refracts the light and then extinguishes it, avoiding the influence of light reflux on the detection, improving the detection quality. The detection sensor installed on the detection mounting table detects the internal air. After the detection, the air flows into the flow control component and the exhaust fan through the dust detection air outlet.
[0009] The present utility model is further configured as: the dust detection housing is provided with a hollow structure, and the dust detection air outlet is provided with a hollow cylindrical structure.

[0012] The present utility model is further configured as: a cylinder push rod is provided on the side of the valve connection plate away from the connection block. The cylinder push rod is slidably connected to a cylinder housing on the side away from the valve connection plate.
[0013] By adopting the above technical solution, the cylinder push rod sliding inside the cylinder housing drives the valve plate and the valve connection plate in the connection block to move on the sliding groove. The air flow is controlled by controlling the gap generated between the connection port and the valve plate, improving the detection quality of the detection device and the detection accuracy.
[0014] The present utility model is further configured as: the flow detection component includes a flow detection housing. An air outlet is provided at the bottom of the flow detection housing. Two groups of fixing blocks are provided at the top of the flow detection housing. The two groups of fixing blocks are fixedly connected to the cylinder housing.
[0015] By adopting the above technical solution, the flow detection device provided inside the flow detection housing monitors and controls the flow rate of the sampler. The internal air is discharged through the air outlet. The fixing blocks provide an installation environment for the cylinder housing.
[0016] In summary, the present application includes at least the following beneficial technical effects:
[0017] 1. The dust inlet introduces the preliminarily filtered air into the dust detection housing. A light source is emitted by the lighting lamp, and the light source is refracted and extinguished upon entry. The refraction and extinction refracts the light and then extinguishes it, avoiding the influence of light backflow on the detection, improving the detection quality. The detection sensor installed on the detection mounting table detects the internal air. After the detection, the air flows into the flow control component and the exhaust fan through the dust detection air outlet.
