Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring, and in particular to a particulate matter monitoring device for dusty environments. Background Technology

[0002] With rapid industrialization, dust pollution has become a significant issue affecting the environment and human health. Particulate matter refers to tiny solid or liquid particles suspended in the air, including dust, smoke, and other particulate matter. These particles not only pollute the environment but also harm human health. Particulate matter monitoring devices are used to monitor the concentration and size distribution of particulate matter in real time. They can detect and monitor the concentration of particulate matter in the environment, providing relevant data and alarm information promptly.

[0003] For example, patent document CN220708992U discloses a particulate matter monitoring device. When in use, air is drawn into the support cylinder by a fan. Larger dust particles are filtered out by the filter membrane, while smaller dust particles enter the monitoring instrument body for monitoring. After monitoring is completed, the threaded sleeve is separated from the threaded cylinder, the support cylinder is removed, and the protective cover with a new filter membrane is replaced.

[0004] In the aforementioned monitoring equipment, if the filter membrane becomes clogged, it will affect the air intake and thus the monitoring results. Therefore, the filter membrane needs to be replaced regularly. When replacing the filter membrane, the monitoring equipment needs to be stopped, and then the filter membrane needs to be manually disassembled and reassembled. Moreover, in environments with high dust levels, the filter membrane needs to be replaced more frequently. If it is not replaced in time, it will affect the normal use of the equipment. Frequent replacement of the filter membrane makes the aforementioned monitoring equipment inconvenient to use. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-10As shown, a particulate matter monitoring device for a dusty environment includes a monitoring body 1. An air inlet pipe 101 is fixed to the top of the monitoring body 1, and a sampling head 102 is fixed to the top of the air inlet pipe 101. The monitoring body 1 has a built-in air pump. When the air pump is activated, air enters the monitoring body 1 through the sampling head 102 and the air inlet pipe 101. A housing 2 is fixed to the air inlet pipe 101, penetrating vertically through the housing 2 and dividing it into left and right chambers. A filter mechanism 3 is installed inside the housing 2. The filter mechanism 3 includes two frames 301, with a filter screen 302 fixed inside each frame 301. A connecting plate 303 is installed between the two frames 301, and rotating shafts 304 are rotatably connected to both sides of the connecting plate 303. The body 301 is fixedly connected to the rotating shaft 304. The front and sides of the air inlet pipe 101 are provided with slots for the frame 301 to pass through. When one frame 301 is located in the air inlet pipe 101, the other frame 301 is located in the cavity of the housing 2. The front of the housing 2 is provided with a translation mechanism 6 for moving the connecting plate 303. The translation mechanism 6 is used to move the two frames 301 left and right by the connecting plate 303, thereby moving the two filters 302 alternately into the air inlet pipe 101. Both sides of the housing 2 are provided with a flipping mechanism 4 for rotating the frame 301. The housing 2 is provided with a power mechanism 5 for driving the flipping mechanism 4 to rotate. The top of the housing 2 is provided with a rinsing mechanism 7 for spraying water on the filters 302.

[0031] The flipping mechanism 4 includes a rotating cylinder 401, which is rotatably connected to the side wall of the housing 2 via bearings. A movable rod 402 is disposed inside the rotating cylinder 401, and a spring 403 is fixed between the movable rod 402 and the rotating cylinder 401. A U-shaped clamp 404 is fixed to one end of the movable rod 402 near the frame 301. A guide strip 405 is fixed to the movable rod 402. A guide groove 406 is formed on the inner wall of the rotating cylinder 401, and the guide strip 405 slides in conjunction with the guide groove 406. Through the guide strip 405 and the guide groove 406, the movable rod 402 can move axially along the rotating cylinder 401, and the rotating cylinder 401 can... The movable rod 402 is able to rotate. When the side of a frame 301 moves into the U-shaped clamp 404, the frame 301 is not completely removed from the slot of the air inlet pipe 101. That is, before the frame 301 contacts the U-shaped clamp 404, the frame 301 is still located in the slot, thus preventing the frame 301 from rotating freely. After the frame 301 engages with the U-shaped clamp 404, the frame 301 continues to move, causing the movable rod 402 to retract into the rotating cylinder 401, and the spring 403 is compressed. At this time, when the frame 301 is completely removed from the slot, the support of the U-shaped clamp 404 can prevent the frame 301 from rotating freely.

[0032] The power mechanism 5 includes two synchronous belt assemblies 501 distributed on both sides of the housing 2. The front end of the synchronous belt assembly 501 is fixedly connected to the rotating drum 401. A transmission shaft 502 is fixed between the rear ends of the two synchronous belt assemblies 501. Specifically, the synchronous belt assembly 501 includes a driving pulley, a driven pulley, and a synchronous belt. The driven pulley is fixedly connected to the rotating drum 401, and the driving pulley is fixedly connected to both ends of the transmission shaft 502. The driving pulley and the driven pulley are connected by a synchronous belt. The transmission shaft 502 is rotatably connected to the rear side of the housing 2. A power motor 503 is fixed on one side of the housing 2. The output shaft of the power motor 503 is fixedly connected to a rotating drum 401.

[0033] The translation mechanism 6 includes a slide bar 601. A through groove 203 is provided on the front side of the housing 2. The slide bar 601 is slidably connected in the through groove 203. The front end of the connecting plate 303 is fixedly connected to the slide bar 601. A rack 602 is fixed to the front side of the slide bar 601 by screws. A translation motor 603 is fixed to the front side of the housing 2. A gear 604 is fixed to the output end of the translation motor 603. The gear 604 meshes with the rack 602. The translation motor 603 drives the rack 602 to translate left and right through the gear 604. The rack 602 drives the slide bar 601 to translate. The slide bar 601 drives the connecting plate 303 to translate. The connecting plate 303 drives the two frames 301 to translate, so that the two filters 302 alternately enter the air intake pipe 101.

[0034] The rinsing mechanism 7 includes a water pump 701, which is fixed to the rear side of the housing 2. The water pump 701 is connected to a water source. A three-way solenoid valve 702 is fixedly connected to the outlet end of the water pump 701. Water pipes 703 are fixedly connected to the two outlet ends of the three-way solenoid valve 702. The two water pipes 703 extend into the two chambers of the housing 2 and are fixedly connected to a spray box 704. When the filter screen 302 moves into the chamber of the housing 2, the spray box 704 is located above the filter screen 302. Multiple nozzles are provided at the bottom of the spray box 704.

[0035] Two conical hoppers 201 are fixed at the bottom of the shell 2. The two conical hoppers 201 correspond to two chambers respectively. A drain pipe 202 is fixed at the bottom of the conical hopper 201. The sewage generated during rinsing is discharged through the drain pipe 202.

[0036] Working Principle: During use, the built-in air pump inside the main body 1 of the monitor is activated. Air enters the main body 1 through the sampling head 102 and the air inlet pipe 101 for monitoring. At this time, the filter 302 on the left side is located inside the air inlet pipe 101. Large particles are filtered as air passes through the filter 302. After a period of use, a large number of large particles accumulate on the filter 302, requiring cleaning. At this time, the translation motor 603 drives the gear 604 to rotate, the gear 604 drives the rack 602 to move to the left, the rack 602 drives the slider 601 to move to the left, the slider 601 drives the connecting plate 303 to move to the left, and the connecting plate 303 drives the two frames 301 to move to the left. This causes the filter 302 on the left side to move into the cavity on the left side of the housing 2, and the filter 302 on the right side to move into the air inlet pipe 101 for filtration. This process can be completed without stopping the machine. During this process, the left frame 301 and the left... The U-shaped clamp 404 on the side engages, clamping the frame 301. Then, the power motor 503 drives the left rotating drum 401 to rotate. Through the transmission of the synchronous belt assembly 501 and the power motor 503, the right rotating drum 401 also rotates synchronously. When the rotating drum 401 rotates, it drives the movable rod 402 to rotate. The movable rod 402 drives the U-shaped clamp 404 to rotate. The U-shaped clamp 404 drives the left frame 301 and the filter screen 302 to rotate 180°, flipping the side of the filter screen 302 with large particles attached to the bottom. Then, the three-way solenoid valve 702 connects the water pump 701 to the water pipe 703 on the left. The water pump 701 draws water and sends it into the water pipe 703 and the spray box 704. The nozzle at the bottom of the spray box 704 sprays high-pressure water evenly onto the left filter screen 302, thus rinsing the filter screen 302. The generated sewage falls into the cone hopper 201 and is discharged through the drain pipe 202.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
