Description

TECHNICAL FIELD

[0001] The utility model relates to atmospheric environment monitoring technical field, concretely is atmospheric particulate matter monitor for atmospheric environment monitoring. BACKGROUND

[0002] Atmospheric environment monitoring is the process that the concentration of pollutants in the atmospheric environment is observed, analyzed and determined its change and environmental impact. The monitoring purpose is: to test and judge the environmental quality: determine whether the atmospheric quality meets the national environmental quality standards. Evaluate the effectiveness of pollution prevention measures: evaluate the effectiveness of atmospheric pollution prevention measures through monitoring data. Predict the development trend of environmental quality: study the change rule of atmospheric environmental quality, and provide the basis for prediction work. Atmospheric particulate matter monitor can measure the concentration of particulate matter in the air in real time and accurately, and the detection data is crucial for evaluating air quality.

[0003] The traditional atmospheric particulate matter monitor for atmospheric environment monitoring has a built-in air pump that continuously pumps air from the external environment. The air contains a large amount of debris such as plastic sheets, which not only causes the air inlet pipe to be blocked, but also reduces the air inlet flow rate. To solve the above problems, some atmospheric particulate matter monitors for atmospheric environment monitoring are connected through a filter box at the end of the air inlet pipe, a screening plate is added to the air inlet end of the filter box, and a liftable cleaning brush is added in the filter box. When the air enters the filter box, the large-area debris in the air is intercepted by the screening plate, and the cleaning brush moves up and down along the back of the screening plate to clean the large-area debris. This not only avoids blockage, but also ensures the air inlet flow rate. However, since the cleaning brush is located on the back of the screening plate, the impurities cleaned will still float around the instrument, which not only cannot guarantee the cleaning effect of the impurities, but also causes some impurities to adhere to the screening plate again. Therefore, an atmospheric particulate matter monitor for atmospheric environment monitoring is proposed. UTILITY MODEL CONTENT

[0028] Threaded screw rod 13 is arranged on the inner wall of filter box 9, and the end of threaded screw rod 13 is coaxially connected with second driving motor 14, and sliding block 15 is sleeved on the surface of threaded screw rod 13, and scraper 16 is arranged between the two groups of sliding blocks 15, and taper pressure rod 17 is uniformly connected to the bottom of scraper 16. The external air is sucked into filter box 9 through the power supply connected to air suction fan 7, and the sundries in the air are intercepted through filter plate 10, so that the air is transported to the inside of outer shell 1 through air guide pipe 8 for atmospheric particulate matter monitoring, and the monitoring data is displayed on display screen 2. The inside of outer shell 1 is provided with a main control circuit board composed of three core modules of a sampling system, a detection system and a data processing system. The sampling system separates different particle sizes of particulate matters through a cutter and collects air samples; the detection system measures the concentration and mass of particulate matters by using optical scattering, beta ray absorption or oscillating balance technology; the data processing system analyzes and calculates the detection signal, and outputs the concentration and mass concentration data through display screen 2 or interface. Meanwhile, the internal monitoring module of the atmospheric particulate matter monitor in the present scheme adopts the existing technical scheme, so it is not described here. The second driving motor 14 is connected to the power supply and drives the threaded screw rod 13 to rotate on the filter box 9, and the sliding block 15 drives the scraper 16 to ascend and descend along the front surface of the filter plate 10 according to the rotation direction of the threaded screw rod 13, so as to drive the sundries on the front surface of the filter plate 10 to fall to the discharge port 11, so that the sundries enter the inside of the receiving box 12 through the discharge port 11, and the taper pressure rod 17 can enter the inside of the discharge port 11 when the scraper 16 moves, which can not only ensure the cleaning effect of the sundries, but also avoid the phenomenon of re-attachment of the sundries; on the other hand, it can avoid the phenomenon of blockage of the sundries in the discharge port 11, which affects the discharging operation.

Since the limiting groove 18 and the limiting plate 19 are both T-shaped design, when the limiting groove 18 and the limiting plate 19 are connected, the limiting plate 19 can only translate along the limiting groove 18 for separation or connection operation, so as to ensure the connection stability of the limiting groove 18 and the limiting plate 19. The two sides of the filter box 9 are rotatably connected with a circular connecting plate 20, and a counterweight clamping plate 21 is connected below the circular connecting plate 20, and the counterweight clamping plate 21 is attached to the outside of the limiting plate 19.

[0032] The present scheme: through the external power supply of the air suction fan 7, the external air is sucked into the filter box 9, and the impurities in the air are intercepted through the filter plate 10, so that the air is transported to the inside of the shell body 1 through the air duct 8 for atmospheric particulate matter monitoring, and the monitoring data is displayed on the display screen 2. At the same time, the atmospheric particulate matter monitor is an existing device, so the composition structure and working principle are not described in detail.

The first driving motor 5 drives the driving wheel 4 to rotate on the shell body 1, and the driving wheel 4 drives the driven wheel 3 to rotate on the shell body 1, so that the driven wheel 3 drives the object seat 6 to rotate in the same direction on the shell body 1.
