Technical Field

[0001] This utility model belongs to the field of dust sampling technology, and in particular relates to a dual-channel dust sampler for detecting the causes of pneumoconiosis. Background Technology

[0002] Pneumoconiosis is one of the most common and serious occupational diseases in my country. Its root cause is the long-term inhalation and retention of industrial dust in the lungs. In order to effectively prevent and control pneumoconiosis, it is crucial to accurately detect and analyze the concentration and composition of dust in the workplace. As the core equipment for collecting dust samples from the air, the reliability of the dust sampler is directly related to the accuracy and validity of the test data. It is a key tool for analyzing the causes of pneumoconiosis, assessing occupational health risks, and implementing health standards.

[0003] However, existing samplers often have structural defects. Dust during the sampling process can easily leak from the dust collection device, leading to inaccurate sampling results and potential contamination of the equipment's interior and the environment. Furthermore, the connection between the sampler body and the base is often directly fixed with bolts, making disassembly and assembly cumbersome and inconvenient for rapid on-site deployment, recovery, or maintenance. To address these issues, we provide a dual-channel dust sampler for detecting the causes of pneumoconiosis. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] Please see Figures 1 to 6 This utility model is a dual-channel dust sampler for detecting the causes of pneumoconiosis. The use of the conical mesh bag 305 and the membrane mesh 303 ensures that the dust will not leak in the dust collection frame 3. At the same time, the use of the assembly block 2 and the plug-in block 104 facilitates the disassembly and assembly of the housing 1.

[0016] Specifically, the housing 1 has two sets of dust collection ports 103 arranged vertically inside. Two sets of suction heads 102, each communicating with the interior of a dust collection port 103, are connected to the left end face of the housing 1. A pump body 101, communicating with the interior of the two sets of dust collection ports 103, is fixed to the right end face of the housing 1. Each set of dust collection ports 103 has a dust collection frame 3 inside. Each dust collection frame 3 has an opening 306 on its side wall near the pump body 101. The interior of the dust collection frame 3 is located near the opening... A membrane mesh 303 is provided on the side wall of 306. A conical mesh bag 305 is provided inside the dust collection frame 3 at the position corresponding to each set of air extraction heads 102. An assembly block 2 is provided directly below the housing 1. An insertion interface 202 is provided on the upper end face of the assembly block 2. An insertion block 104 is inserted into the insertion interface 202. A locking plate 106 is fixed on the upper end face of the insertion block 104 and bolted to the lower end face of the housing 1. Insertion holes 105 are provided on the left and right sides of the surface wall of the insertion block 104.

[0017] The operation process of this embodiment is as follows: Using the above-described structure, the pump body 101 is controlled to operate. The pump body 101 draws ambient air into the dust collection frame 3 through the suction head 102. The air is then blocked by the membrane screen 303 and the conical mesh bag 305, causing the dust to remain in the dust collection frame 3. Membrane screens 303 and conical mesh bags 305 of different mesh sizes are installed in different dust collection frames 3. Two parallel dust samples are collected simultaneously from both dust collection frames 3 at the same point. The conical mesh bag 305 used is used to collect dust samples from the dust collection frame. The dust in the dust frame 3 is limited by the membrane mesh 303 and the conical mesh bag 305, ensuring that the dust does not leak in the dust frame 3. At the same time, the plug block 104 is inserted into the plug interface 202, so that the plug rod 402 will be engaged into the corresponding plug hole 105, so that the assembly block 2 and the plug block 104 are assembled and connected together, realizing the detachable connection between the assembly block 2 and the plug block 104. This facilitates the control of the assembly between the assembly block 2 and the plug block 104, and ensures that the housing 1 can be easily disassembled and assembled. Example 2

[0018] Please see Figure 2 and Figure 3 Based on Example 1, the membrane mesh 303 is stabilized by limiting the position of the membrane mesh 303 by two sets of L-shaped strips 302, thus ensuring that the membrane mesh 303 can stably filter dust.

[0019] Specifically, an air pipe 301 is fixed to the inner wall of the dust collection frame 3 at the position of each set of air extraction heads 102. An annular plate 304 is fixed to the end face of the two sets of conical mesh bags 305 near the air pipe 301. The annular plate 304 is installed in the air pipe 301 by bolts. L-shaped strips 302 are fixed to the inner wall of the dust collection frame 3 on both sides of the opening 306. The two ends of the membrane mesh 303 are slidably inserted between the two sets of L-shaped strips.

[0020] The operation process of this embodiment is as follows: With the above-described structure, when the dust collection frame 3 is removed from the dust collection port 103, the membrane screen 303 between the two sets of L-shaped strips 302 can be directly pulled out, making it easy to disassemble the membrane screen 303 and replace it. After the membrane screen 303 is inserted between the two sets of L-shaped strips 302, the L-shaped strips 302 abut against the membrane screen 303, so that the membrane screen 303 stably blocks the opening 306, blocking the outside air and ensuring that the dust remains in the dust collection frame 3. Example 3

[0021] Please see Figure 4 , Figure 5 and Figure 6 Based on Example 1, the use of spring 404 facilitates the stable insertion of plug rod 402 into plug hole 105, ensuring the stable combination between plug block 104 and assembly block 2.

[0022] Specifically, the inner wall of the insertion interface 202 is provided with a movable hole 204 corresponding to the position of each set of insertion holes 105. The assembly block 2 has multiple sets of movable openings 203 that communicate with the inner end faces of the movable holes 204. The surface wall of the assembly block 2 is provided with a pull hole 205 corresponding to the position of each set of movable openings 203. A combination plate 4 is provided on the left and right sides of the surface wall of the assembly block 2. A movable rod 401 is fixed on the side wall of the combination plate 4 corresponding to the position of each set of pull holes 205. A circular plate 403 is fixed to the end face of the movable opening 203. A plug rod 402 is fixed to the end face of the circular plate 403 opposite to the moving rod 401, and the plug rod 402 is inserted into the corresponding plug hole 105. A spring 404 is fixed to the end face of the circular plate 403 and sleeved on the moving rod 401. The other end of the spring 404 abuts against the inner end face of the movable opening 203. An mounting plate 201 is fixed to the lower end face of the assembly block 2.

[0023] The operation process of this embodiment is as follows: With the above structure, when it is necessary to remove the plug-in block 104 from the plug-in interface 202, the combination plate 4 can be controlled to move away from the assembly block 2. The combination plate 4 controls the circular plate 403 to move in the movable opening 203 through the moving rod 401, and the circular plate 403 controls the plug-in rod 402 to move out of the plug-in hole 105, so that the plug-in block 104 can be removed from the plug-in interface 202. At the same time, when the circular plate 403 is controlled to move in the movable opening 203, the circular plate 403 will compress the spring 404. Therefore, when the linkage plate is released, the spring 404 will push the circular plate 403 to reset and push the plug-in rod 402 to re-insert into the plug-in hole 105. The mounting plate 201 used is installed on the stand with bolts so as to stand the housing 1 upright.
