[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a dust concentration detection device for environmental monitoring. Background Technology
[0002] Industrial production processes, especially in manufacturing, mining, and quarrying, generate large amounts of dust. Dust emitted into the air pollutes the environment and affects air quality. Furthermore, long-term inhalation of dust by workers can lead to various respiratory diseases.
[0003] Environmental dust monitoring, assessment of dust pollution levels, and the development and implementation of effective control measures are crucial for protecting environmental safety. Currently, commercially available methods for dust concentration detection mainly include gravimetric methods, light scattering methods, laser dust metering methods, inductive methods, and particle counter methods. However, the concentration detection equipment used is generally inconvenient to carry and difficult to apply to dust concentration detection operations in different environments. Therefore, this application provides a dust concentration detection device for environmental monitoring to meet this need. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a dust concentration detection device for environmental monitoring to solve the problem that existing dust concentration detection equipment is not portable.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] An environmental monitoring dust concentration detection device includes a housing with a lid. An air intake box is installed at one end of the housing, and an electronic scale is installed at the end of the housing furthest from the air intake box. A sleeve and an air inlet pipe are sequentially installed on the end face of the air intake box, and the sleeve and air inlet pipe are in communication with the interior of the air intake box. The air intake box can draw in outside air through the sleeve and air inlet pipe. A detachable membrane frame is installed on the sleeve for filtering the air entering the air intake box through the air inlet pipe.
[0007] Optionally, a piston plate is installed inside the air intake box, and an air inlet hole for communicating with the sleeve is opened on the end face of the air intake box. A piston rod is connected to the end of the piston plate away from the air inlet hole, and the piston rod passes through the end face of the air intake box away from the air inlet hole and is connected to a push-pull handle.
[0008] Optionally, a sleeve is fixedly inserted through the end face of the box away from the air intake box, and a rope is inserted through the sleeve. One end of the rope extends into the air intake box and is tied to the push-pull handle, and the other end of the rope extends out of the box and is tied with a pull ring.
[0009] Optionally, a storage box is also provided at the end of the box body away from the air intake box. The storage box stores multiple membrane frames. The storage box and the electronic scale are located on both sides of the push-pull handle.
[0010] Optionally, the end of the air intake pipe away from the air intake box penetrates the end wall of the box body, and the end of the air intake pipe extending outside the box body is threaded with a sealing cap.
[0011] Optionally, one side of the lid is hinged to the box body, and the other side of the lid is fitted with a latch between it and the side wall of the box body. A handle is also provided on the side wall of the box body.
[0012] Optionally, the membrane frame includes a frame body and a dust-blocking membrane embedded in the frame body, wherein the frame body is vertically inserted into the casing through the top surface of the casing.
[0013] Optionally, an end plate is provided at the top of the frame, and the end plate abuts against the top of the sleeve box.
[0014] Optionally, through holes are provided at both ends of the end plate and on the upper surface of the sleeve, and screws are threaded into the through holes, with an end block provided at the top of the screws.
[0015] Optionally, a sealing gasket is adhered to the upper surface of the housing.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, by setting up an air intake box and an electronic scale inside the casing, the device is placed within the environmental monitoring area. Pulling the rope pulls the push-pull handle and piston rod, causing the piston plate to move. This allows the air intake box to quantitatively draw air from the environmental monitoring area through the casing and membrane frame. During the process of drawing the air into the air intake box, the air passes through the dust-blocking membrane in the membrane frame. The dust-blocking membrane adsorbs and captures dust particles suspended in the air. The membrane frame is then removed and weighed using the electronic scale. By comparing the weight difference before and after weighing the membrane frame, the mass per unit volume of dust concentration in the area to be monitored can be obtained. The dust concentration can be calculated based on the fixed volume of air drawn into the air intake box and the mass difference obtained from weighing, thus achieving the purpose of dust concentration detection within the environmental monitoring range. Furthermore, by pushing the push-pull handle to reset the piston plate and inserting a new membrane frame into the casing, the device can be used again for dust concentration detection in the environment. This allows for repeated detection operations. The overall structure is reasonable, and the centralized assembly inside the casing with a cover makes the device easy to carry and suitable for dust concentration detection operations in various environments.

[0032] like Figure 1 and Figure 2As shown in the figure, an embodiment of this utility model provides a dust concentration detection device for environmental monitoring, including a housing 1, a housing 1 equipped with a housing cover 2, an air intake box 3 installed at one end of the housing 1, and an electronic scale 4 installed at the end of the housing 1 away from the air intake box 3. A sleeve 5 and an air inlet pipe 7 are sequentially installed on the end face of the air intake box 3. The sleeve 5 and the air inlet pipe 7 are in communication with the interior of the air intake box 3, allowing the air intake box 3 to draw in outside air. A membrane frame 6 is detachably installed on the sleeve 5, which is used to filter the air entering the air intake box 3 through the air inlet pipe 7. When the device is placed within an environmental monitoring area, the air intake box 3 draws in air from the environmental monitoring area through the sleeve 5 and the membrane frame 6. The air is drawn into the suction box 3 in a quantitative manner. During the process of air being drawn into the suction box 3, it passes through the membrane frame 6. The membrane frame 6 adsorbs and captures dust particles suspended in the air. After the suction box 3 has finished drawing air, the membrane frame 6 is removed and weighed using an electronic scale 4. The weight difference before and after the membrane frame 6 is compared. This weight difference is the mass of the dust concentration in the area to be monitored. Then, based on the fixed volume of air drawn into the suction box 3 and the mass difference obtained by weighing, the dust concentration can be calculated, thus achieving the purpose of dust concentration detection within the environmental monitoring range. The structure is designed to be centrally assembled in the box body 1 and equipped with a box cover 2, making the device easy to carry and suitable for dust concentration detection operations in various environments.
[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the suction box 3 is equipped with a piston plate 22. An air inlet 23 for communicating with the sleeve 5 is opened on the end face of the suction box 3. A piston rod 24 is connected to the end of the piston plate 22 away from the air inlet 23. The piston rod 24 passes through the end face of the suction box 3 away from the air inlet 23 and is connected to a push-pull handle 25. A sleeve 13 is fixedly inserted on the end face of the box body 1 away from the suction box 3. A rope 11 is inserted into the sleeve 13. One end of the rope 11 extends into the suction box 3 and is tied to the push-pull handle 25. The other end of the rope 11 extends out of the box body 1 and is tied to a pull ring 12. Pulling the rope 11 pulls the push-pull handle 25 and the piston rod 24 to move the piston plate 22. This allows the suction box 3 to quantitatively draw air within the environmental monitoring area into the suction box 3 through the sleeve 5 and the membrane frame 6. By pushing the push-pull handle 25, the piston plate 22 is reset and can be used again for detecting dust concentration in the environment.
[0034] like Figures 1 to 3 As shown, the end of the air inlet pipe 7 away from the air intake box 3 passes through the end wall of the box body 1, and the end of the air inlet pipe 7 extending outside the box body 1 is threaded with a sealing cap 8 to prevent dust from entering the air inlet pipe 7 during carrying. One side of the box cover 2 is hinged to the box body 1, and the other side of the box cover 2 is fitted with a latch 10 between it and the side wall of the box body 1. A handle 9 is also provided on the side wall of the box body 1 for easy carrying and storage.
[0035] like Figures 1 to 4 As shown, a storage box 14 is also provided at the end of the box body 1 away from the suction box 3. The storage box 14 stores a plurality of membrane frames 6. The storage box 14 and the electronic scale 4 are located on both sides of the push-pull handle 25. The membrane frame 6 includes a frame body 16 and a dust-blocking membrane 17 embedded in the frame body 16. The frame body 16 is inserted vertically into the sleeve 5 through the top surface of the sleeve 5. The dust-blocking membrane 17 can adsorb and capture dust particles suspended in the air. An end plate 18 is provided at the top of the frame body 16. The end plate 18 abuts against the top of the sleeve 5. Through holes 19 are provided at both ends of the end plate 18 and the upper surface of the sleeve 5. Screws 20 are threaded into the through holes 19. An end block 21 is provided at the top of the screws 20. A sealing gasket 15 is adhered to the upper surface of the sleeve 5 to seal the frame body 16 inside the sleeve 5.
[0036] The working principle of the technical solution provided by this utility model is as follows:
[0037] In use, place the device within the environmental monitoring area, then open the cover 2, remove the sealing cover 8 from the end of the air inlet pipe 7, and then pull the rope 11 to pull the push-pull handle 25 and piston rod 24 to move the piston plate 22. This causes the air intake box 3 to quantitatively draw air from the environmental monitoring area through the sleeve 5 and membrane frame 6 into the air intake box 3. During the process of drawing air into the air intake box 3, the air passes through the dust-blocking membrane 17 in the membrane frame 6. The dust-blocking membrane 17 can adsorb and capture dust particles suspended in the air. After the air intake box 3 has finished drawing air, remove the membrane frame 6 and weigh it using the electronic scale 4. By comparing the weight difference before and after the membrane frame 6, this weight difference represents the mass of dust concentration in the area to be monitored. Then, based on the fixed volume of air drawn into the suction box 3 and the mass difference obtained by weighing, the dust concentration can be calculated, achieving the purpose of dust concentration detection within the environmental monitoring range. Furthermore, by pushing the push-pull handle 25 to reset the piston plate 22, a new membrane frame 6 can be inserted into the casing 5, allowing it to be used again for dust concentration detection in the environment. The overall structure is reasonable, with the components centrally assembled in the casing 1 and equipped with a casing cover 2, making the device easy to carry and more suitable for dust concentration detection operations in various environments.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
