Description

Technical Field

[0001] This utility model relates to the field of dust monitoring technology, and in particular to a dust monitoring device with dust filtration and sampling capabilities. Background Technology

[0002] Dust pollution is a serious problem in industrial production, posing a threat to workers' health and affecting the normal operation of production equipment. To effectively control dust pollution, various dust monitoring devices using filtration and sampling have emerged. Currently, existing dust monitoring devices on the market meet the needs of dust monitoring and control to a certain extent, but with the continuous development of industrial production and increasingly stringent environmental protection requirements, some shortcomings of existing devices are gradually becoming apparent.

[0003] Existing dust monitoring devices for dust filtration and sampling typically employ traditional filtration methods, such as bag filters and cartridge filters. Structurally, they generally consist of a dust collection hood, a filter, and an exhaust fan. The dust collection hood collects dust-laden air, the filter filters the dust-laden air, and the exhaust fan provides suction to draw the dust-laden air into the device. For dust sampling, some devices employ complex sampling systems that require professional operation, and the sampling process is relatively cumbersome.

[0004] In practical applications, existing dust monitoring devices that use dust filtration sampling have several drawbacks. For example, in some industrial production workshops, the filter screens of existing devices are inconvenient to install and remove. Traditional bolt assembly methods require tools, are cumbersome, and time-consuming. This is because traditional designs do not fully consider the user's need for convenience in actual use, resulting in low efficiency when cleaning the filter screen. Furthermore, existing devices also have shortcomings in dust sampling. Some devices have complex sampling systems that are difficult to operate, making it difficult to quickly obtain representative dust samples. Therefore, this art proposes a dust monitoring device with dust filtration sampling to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dust monitoring device with dust filtration sampling, aiming to improve the problem that the filter screen in the existing dust monitoring device with dust filtration sampling requires the assistance of other tools for disassembly and cleaning after long-term use, which is quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust monitoring device with dust filtration and sampling, comprising a dust collection hood and a sampling component. The sampling component is located directly below the dust collection hood. A dust monitoring device is installed inside the dust collection hood. A connecting pipe is fixedly connected to the top of the dust collection hood. A filter screen is installed inside the connecting pipe. A disassembly and assembly component is installed on the outside of the connecting pipe. The disassembly and assembly component is used to quickly disassemble and assemble the filter screen. The disassembly and assembly component includes a connecting plate. One side of the connecting plate is fixedly connected to the outside of the filter screen. A limit plate is rotatably connected to the outside of the connecting pipe. A limit block is fixedly connected to the outside of the connecting pipe. A torsion spring is sleeved on the outer circumference of the rotating shaft of the limit plate.

[0007] Furthermore, one end of the torsion spring is fixedly connected to the outside of the connecting tube, and the other end of the torsion spring is fixedly connected to the outside of the limiting plate, with the outside of the limiting plate fitting against the outside of the limiting block.

[0008] Furthermore, a sealing ring is fixedly connected to one side of the connecting plate, and a sealing groove is provided on the outer side of the connecting pipe.

[0009] Furthermore, the outer part of the sealing ring is engaged with the inside of the sealing groove, and a handle is fixedly connected to the outer side of the connecting plate.

[0010] Furthermore, the sampling assembly includes a collection hopper and a barrier block. The collection hopper is fixedly connected to the inner wall of the dust collection hood, and two fixing blocks are fixedly connected to the outer side of the collection hopper. The bottom of the fixing blocks is provided with a slot.

[0011] Furthermore, the barrier block is located at the bottom of the collection hopper, and two locking blocks are fixedly connected to the outer side of the barrier block, with the outer side of the locking blocks engaging with the inside of the locking slot.

[0012] Furthermore, both the fixing block and the card block have connecting holes inside, and a pin is slidably connected inside the connecting hole, and the pin passes through the connecting hole inside both the fixing block and the card block.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by rotating the limiting plate to separate it from the connecting plate, and then pulling the handle, the filter screen can be pulled out from the inside of the connecting pipe for cleaning. Compared with the traditional bolt assembly method, this design does not require other tools, greatly saving cleaning time. Workers can quickly clean the filter screen to ensure that the filter screen always maintains a good filtration effect, thereby ensuring that the device can continuously and effectively collect dust, reducing maintenance costs, and also reducing the risk of equipment failure due to filter screen blockage, providing a reliable guarantee for dust control in production and processing workshops.

[0015] 2. In this utility model, dust particles, after being blocked by the filter screen, fall into the collection hopper for collection. The dust monitoring equipment can monitor the dust situation inside the dust collection hood in real time, providing accurate data support for dust control. By pulling out the pin to release the fixing of the blocking block, the blocking block can be removed, allowing the dust in the collection hopper to fall into the container as a sample. This allows for the rapid acquisition of representative dust samples, providing a strong basis for dust analysis and control. At the same time, after the dust in the collection hopper is discharged, the collection hopper can continue to collect dust, ensuring the continuous working capability of the device.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a dust monitoring device with dust filtration and sampling, comprising a dust collection hood 1 and a sampling component. The sampling component is located directly below the dust collection hood 1. The dust collection hood 1 can be rationally arranged according to the size and shape of the processing area to ensure maximum dust collection. A dust monitoring device 2 is installed inside the dust collection hood 1, which can monitor the dust situation inside the dust collection hood 1 in real time, providing accurate data support for subsequent dust control. A connecting pipe 3 is fixedly connected to the top of the dust collection hood 1, serving to connect an external exhaust fan and a corrugated pipe to extract dust into the device for processing. A filter screen 4 is installed inside the connecting pipe 3, which can effectively filter dust, preventing larger dust particles from entering subsequent processing equipment and protecting the normal operation of the equipment. A disassembly and assembly component is provided on the outside of the connecting pipe 3, used for quick disassembly and assembly of the filter screen 4. The disassembly and assembly component includes a connecting plate 5, one side of which is fixedly connected to the outside of the filter screen 4, providing stable support and connection for the filter screen 4. A limiting plate 10 is rotatably connected to the outer side of the connecting pipe 3, playing a crucial role in the installation and disassembly of the device. A limiting block 9 is fixedly connected to the outer side of the connecting pipe 3, restricting the rotation range of the limiting plate 10 and ensuring it functions in the correct position. A torsion spring 11 is sleeved around the outer circumference of the rotating shaft of the limiting plate 10. One end of the torsion spring 11 is fixedly connected to the outer side of the connecting pipe 3, and the other end is fixedly connected to the outer side of the limiting plate 10. The torsion spring 11 provides a certain elastic force to the limiting plate 10, allowing it to remain in a specific position when no external force is applied. When the filter screen 4 needs to be installed, it is inserted into the connecting pipe 3. The sealing ring 6 on the connecting plate 5 engages in the sealing groove 8 on the outer side of the connecting pipe 3, ensuring a tight seal. Then, the limiting plate 10 is rotated to fit against the outer side of the connecting plate 5. Under the action of the torsion spring 11, the limiting plate 10 firmly secures the connecting plate 5, thus enabling the rapid installation of the filter screen 4. When the device has been used for an extended period, the limiting plate 10 can be rotated to separate from the outer side of the connecting plate 5. Then, the handle 7 can be pulled to remove the filter screen 4 from the inside of the connecting pipe 3 for cleaning. Compared to traditional bolt assembly, this assembly method eliminates the need for additional tools during installation and disassembly, making it more convenient. Traditional bolt assembly requires tools such as screwdrivers, which is cumbersome and can easily damage the connecting parts. This quick-assembly and disassembly assembly, however, allows for easy installation and removal of the filter screen 4 simply by rotating the limiting plate 10 and pulling the handle 7, greatly improving work efficiency.

[0026] Specifically, firstly, the entire device is installed in the production workshop where dust is generated, with the dust collection hood 1 positioned directly above the processing area. This positioning of the dust collection hood 1 maximizes coverage of the dust-generating area, ensuring efficient dust collection when the exhaust fan is operating. This effectively reduces the spread of dust within the workshop, minimizing the harm to worker health and production equipment. An external exhaust fan and corrugated pipe are connected to the top of the connecting pipe 3 to extract dust, which is then filtered by the filter screen 4. The exhaust fan provides strong suction, drawing dust-laden air into the device through the connecting pipe 3. The filter screen 4 effectively blocks larger dust particles, preventing them from entering subsequent processing equipment and protecting its normal operation. Simultaneously, the filtered air reduces environmental pollution. When the device has been used for an extended period, the limiting plate 10 can be rotated to separate from the outer side of the connecting plate 5, and then the handle 7 can be pulled to remove the filter screen 4 from the inside of the connecting pipe 3 for cleaning. This assembly method, compared to traditional bolt assembly, eliminates the need for additional tools during installation and disassembly, making it more convenient. Traditional bolt assembly requires tools such as screwdrivers, which is not only cumbersome but can also damage connecting parts during disassembly. This quick-assembly method, however, allows for easy removal and cleaning of the filter screen 4 simply by rotating the limit plate 10 and pulling the handle 7. This significantly saves cleaning time and improves work efficiency. Furthermore, regular cleaning of the filter screen 4 ensures its filtration effect, guaranteeing that the device can always effectively collect dust.

[0027] Reference Figures 4-6The sampling assembly includes a collection hopper 12 and a blocking block 17. The collection hopper 12 is fixedly connected to the inner wall of the dust collection hood 1. The shape and size of the collection hopper 12 are reasonably designed to effectively collect dust that falls after being blocked by the filter screen 4. Two fixing blocks 13 are fixedly connected to the outer side of the collection hopper 12, providing support for the installation of the blocking block 17. A slot 14 is provided at the bottom of the fixing block 13, which cooperates with the locking block 15 on the outer side of the blocking block 17 to fix the blocking block 17. The blocking block 17 is located at the bottom of the collection hopper 12 and can prevent the dust in the collection hopper 12 from falling directly, serving as a temporary dust storage function. Two locking blocks 15 are fixedly connected to the outer side of the blocking block 17. The outer side of the locking block 15 engages with the inside of the locking slot 14. Through the cooperation of the locking block 15 and the locking slot 14, the blocking block 17 can be firmly installed at the bottom of the collection hopper 12. Both the fixing block 13 and the locking block 15 have connecting holes 16 inside. A pin 18 is slidably connected inside the connecting hole 16, and the pin 18 passes through the connecting hole 16 inside both the fixing block 13 and the locking block 15. The pin 18 further strengthens the fixation of the barrier block 17, ensuring that the barrier block 17 will not accidentally fall off during device operation. When dust sampling is required, the container can be placed at the bottom of the collecting hopper 12, and then the two pins 18 can be pulled out from the connecting holes 16 to release the fixation of the barrier block 17, allowing it to be removed. The dust inside the collecting hopper 12 will then fall into the container. After the dust in the collecting hopper 12 is discharged, the collecting hopper 12 can continue to collect dust, and the dust inside the barrier block 17 can be used as a sample. This sampling method is simple and convenient, enabling rapid acquisition of dust samples and providing strong support for dust analysis and control.

[0028] Specifically, dust particles blocked by filter screen 4 fall into the collection hopper 12 for collection, and the dust monitoring device 2 can detect the dust inside the dust collection hood 1. The design of the collection hopper 12 effectively collects the dust blocked by filter screen 4, preventing the dust from spreading back into the air. The dust monitoring device 2 monitors the dust situation inside the dust collection hood 1 in real time, providing accurate data support for dust control. Based on the data from the dust monitoring device 2, staff can adjust the power and operating time of the exhaust fan to achieve the best dust collection effect. A container can be placed at the bottom of the collection hopper 12, and then the two pins 18 can be pulled out of the connection hole 16 to release the fixation of the blocking block 17, allowing the blocking block 17 to be removed. The dust inside the collection hopper 12 will then fall into the container. After discharging the dust from the collection hopper 12, it can continue to collect dust, and the dust inside the blocking block 17 can be used as a sample. This sampling method is simple and convenient, enabling rapid acquisition of dust samples and providing strong support for dust analysis and control. Analysis of the sampled dust reveals its composition and source, allowing for targeted control measures. Simultaneously, the collection hopper 12 continues to collect dust, ensuring the continuous operation of the device.

[0029] Working principle: First, the entire device is installed in the production and processing workshop where dust is generated, with the dust collection hood 1 located directly above the processing area. The external exhaust fan and corrugated pipe are connected to the top of the connecting pipe 3 to extract dust, and the filter screen 4 is used for filtration. When the device is used for a long time, the limiting plate 10 can be rotated to separate from the outside of the connecting plate 5, and then the handle 7 can be pulled to pull the filter screen 4 out from the inside of the connecting pipe 3 for cleaning. Compared with the traditional bolt assembly, this assembly method saves the need for other tools during installation and disassembly, making it more convenient.

[0030] In addition, after being blocked by the filter screen 4, the dust will fall into the inside of the collection hopper 12 for collection. The dust monitoring device 2 can detect the dust inside the dust collection hood 1. The container can be placed at the bottom of the collection hopper 12, and then the two pins 18 can be pulled out from the connection hole 16 to release the fixation of the blocking block 17. The blocking block 17 can be removed, and the dust inside the collection hopper 12 will fall into the container. After the dust in the collection hopper 12 is discharged, the collection hopper 12 can continue to collect dust, and the dust inside the blocking block 17 can be used as a sample for sampling.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
