Description

Technical Field

[0001] The present invention relates to the technical field of dust monitoring, and in particular to a dust concentration monitoring device and a monitoring method. Background Art

[0002] The dust formed in the production process is called production dust. The sources of production dust are very wide. The main sources are solid materials formed by mechanical impact, grinding, and rolling, solid particles suspended in the air by airflow, smoke formed by condensation or oxidation of steam produced in the air when the material is heated, and smoke formed by incomplete combustion of organic matter. It is difficult to avoid the generation of production dust during the operation process. The generated dust spreads into the air, resulting in the presence of production dust in the air of the workplace. Production dust with larger particle size will settle under the action of gravity and other forces, while production dust with smaller particle size may be suspended in the air of the workplace, causing environmental pollution in the workplace. Accumulation to a certain concentration may cause explosion accidents, and it will also cause harm to the health of workers. Therefore, monitoring the dust concentration in the workplace is of great significance for ensuring safe production and protecting occupational health.

[0003] The light scattering method is currently widely used in the monitoring of dust concentration in the workplace. Many dust concentration sensors based on the light scattering principle have been developed to monitor the dust concentration in the workplace. The principle of measuring dust concentration by the light scattering method is that in the process of light propagation, the light propagation direction is changed by the influence of dust particles. When the light source emits light, due to the effect of dust in the photosensitive area, the light scattered in all directions is collected as much as possible by the spherical condenser and then propagated to the light receiver. The receiver converts the received light intensity into an electrical signal, and then converts it into different light or electrical signals according to different dust concentrations. The light scattering method has good accuracy and high reliability in dust concentration detection, but in actual application, the detection light path of the dust concentration detection equipment based on the light scattering method is easily contaminated by dust, resulting in the equipment measurement results not being consistent with the actual dust concentration. Summary of the invention

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] The dust formed in the production process is called production dust. The sources of production dust are very wide. The main sources are solid materials formed by mechanical impact, grinding, and rolling, solid particles suspended in the air by airflow, smoke formed by condensation or oxidation of steam produced in the air when the material is heated, and smoke formed by incomplete combustion of organic matter. It is difficult to avoid the generation of production dust during the operation process. The generated dust spreads into the air, resulting in the presence of production dust in the air of the workplace. Production dust with larger particle size will settle under the action of gravity and other forces, while production dust with smaller particle size may be suspended in the air of the workplace, causing environmental pollution in the workplace. Accumulation to a certain concentration may cause explosion accidents, and it will also cause harm to the health of workers. Therefore, monitoring the dust concentration in the workplace is of great significance for ensuring safe production and protecting occupational health.

[0039] The light scattering method is currently widely used in the monitoring of dust concentration in the workplace. Many dust concentration sensors based on the light scattering principle have been developed to monitor the dust concentration in the workplace. The principle of measuring dust concentration by the light scattering method is that in the process of light propagation, the light propagation direction is changed by the influence of dust particles. When the light source emits light, due to the effect of dust in the photosensitive area, the light scattered in all directions is collected as much as possible by the spherical condenser and then propagated to the light receiver. The receiver converts the received light intensity into an electrical signal, and then converts it into different light or electrical signals according to different dust concentrations. The light scattering method has good accuracy and high reliability in dust concentration detection, but in actual application, the detection light path of the dust concentration detection equipment based on the light scattering method is easily contaminated by dust, resulting in the equipment measurement results not being consistent with the actual dust concentration.

[0040] The main purpose of the present invention is to provide a dust concentration monitoring device and a monitoring method to solve the problem that the detection light path of the dust concentration detection equipment using the light scattering method in the prior art is easily contaminated by dust, resulting in inaccurate measurement results.

[0041] The dust concentration monitoring device provided in the present application comprises: a monitoring device 8, the monitoring device 8 is used to monitor dust, the monitoring device 8 has a receiving cavity 80 for monitoring dust concentration, and a connecting pipe 7 connected to the receiving cavity 80 for dust flow;

[0042] The ventilation air path 9 is arranged on a side of the monitoring device 8 away from the connecting pipe 7 and is connected to the accommodating cavity 80 to transport dust into the accommodating cavity 80;

[0043] The cleaning component is used to communicate with the connecting pipe 7 so that when the concentration of dust in the accommodating cavity 80 is greater than or equal to a set threshold, the cleaning component is controlled to deliver airflow into the monitoring device 8 and out from the ventilation air path 9 to clean the accommodating cavity 80.

[0044] Specifically, Figure 1 to Figure 2 As shown, the dust concentration monitoring device provided by the present application includes a monitoring device 8, which can be used to detect the concentration of dust. The monitoring device 8 has a containing cavity 80 for monitoring the dust concentration, and also has a connecting pipe 7 connected to the containing cavity 80 for the flow of dust. A ventilation air path 9 is provided on the side of the monitoring device 8 away from the connecting pipe 7. The ventilation air path 9 has a vent 10, and dust can be transported into the containing cavity 80 through the ventilation air path 9 for monitoring by the monitoring device 8. The other end of the connecting pipe 7 is also connected to a cleaning component. When the monitoring device 8 detects that the concentration of dust in the containing cavity 80 is greater than or equal to a set threshold value, the cleaning component is controlled to transport airflow into the monitoring device 8 to blow the dust in the monitoring device 8 out of the ventilation air path 9, thereby cleaning the containing cavity 80.

[0045] By providing a cleaning component, the dust in the monitoring device 8 can be cleaned in time, and inaccuracies can be avoided during the monitoring process of the monitoring device 8, so that corresponding measures can be taken according to the monitoring results of the monitoring device 8. The cleaning component of the monitoring device is automatically started to deliver a clean airflow to the inside of the monitoring device 8, effectively removing dust accumulation in the accommodating cavity 80, avoiding light path pollution, and thus significantly improving the accuracy of dust concentration detection.

[0046] The automatic operation of the cleaning components reduces the need for regular manual cleaning of the monitoring device 8, reduces maintenance costs and frequency, extends the maintenance cycle of the equipment, and improves the overall operating efficiency of the monitoring system.

[0047] The dust in the accommodating cavity 80 is cleaned regularly to prevent the particles from being deposited in the monitoring device 8 , thereby avoiding equipment failure caused by dust blockage or pollution and enhancing the stability and reliability of the monitoring device 8 .

[0048] Further, the cleaning component comprises: a first pump body 2;

[0049] a first delivery pipeline 4, wherein the first pump body 2 is connected to the first delivery pipeline 4 to deliver airflow to the first delivery pipeline 4;

[0050] The filter component 5 has an inlet end connected to the outlet end of the first delivery pipe 4, and the outlet end of the filter component 5 is used to connect to an end of the connecting pipe 7 away from the accommodating cavity 80 to filter the airflow delivered from the first delivery pipe 4 and deliver it to the accommodating cavity 80 to clean the accommodating cavity 80.

[0051] Specifically, the cleaning component includes a first pump body 2, and also includes a first conveying pipe 4 connected to the output end of the first pump body 2. The airflow in the outside is conveyed from the first conveying pipe 4 to the accommodating cavity 80 through the first pump body 2. A filtering component 5 is also provided between the first conveying pipe and the accommodating cavity 80. The filtering component 5 is used to filter the airflow conveyed by the first pump body 2 to remove dust contained in the airflow conveyed from the first pump body 2, and convey the clean airflow to the accommodating cavity 80 to clean the accommodating cavity 80.

[0052] The filter component 5 can effectively remove dust from the airflow delivered by the first pump body 2, ensuring that the airflow entering the cavity 80 of the monitoring device 8 is clean, thereby avoiding secondary contamination of the monitoring device 8 during the cleaning process and improving the cleaning efficiency and detection accuracy of the monitoring device.

[0053] Through the cooperation of the first pump body 2 and the first delivery pipe 4, the delivery volume and speed of the clean airflow can be accurately controlled to ensure the effectiveness of the cleaning process. At the same time, the setting of the filter component 5 prevents the impurities that may exist in the clean airflow from damaging the monitoring device 8, making the cleaning process more optimized.

[0054] The use of the filter component 5 reduces the pollution inside the monitoring device 8, thereby reducing the maintenance frequency of the monitoring device 8, reducing the maintenance time, and improving the continuous operation capability of the device.

[0055] The automated design of the cleaning components ensures that the monitoring device 8 can be effectively cleaned before each monitoring cycle or during the monitoring interval, thereby avoiding inaccurate measurements due to contamination of the monitoring device 8 and improving the reliability and stability of the monitoring device 8.

[0056] The filter component 5 can adapt to the dust types and concentrations in different environments, and can provide clean airflow through filtering even in an environment with high dust concentration, thereby ensuring the normal operation of the monitoring device 8 in various complex environments.

[0057] Furthermore, the filter component 5 comprises: a filter housing having a filter cavity;

[0058] At least two filter screens are disposed in the filter cavity, and at least two filter screens are arranged along the extension direction of the first conveying pipe 4 to filter dust contained in the airflow conveyed from the first conveying pipe 4 to the accommodating cavity 80 .

[0059] Specifically, the filter component 5 includes a filter shell having a filter cavity inside the filter shell. At least two filter nets are provided in the filter cavity to filter the airflow delivered from the first pump body 2 to the first delivery pipe 4 to ensure the cleanliness of the airflow input into the accommodating cavity 80.

[0060] Using at least two filters can form a multiple filtering barrier, effectively capturing dust particles of different sizes, ensuring that the airflow entering the monitoring device accommodating cavity 80 has a higher degree of cleanliness, and reducing the impact on monitoring accuracy.

[0061] By providing multiple layers of filter screens, the first layer of filter screens can initially capture large dust particles, reducing the burden of the latter layer of filter screens, thereby extending the service life of the entire filter component 5 and reducing the frequency of maintenance and replacement of the filter screens.

[0062] The multi-layer filtration design makes the self-cleaning function of the device more perfect, and can continuously provide clean airflow even in high dust concentration environments, ensuring the normal operation of the monitoring equipment 8 under harsh conditions.

[0063] Furthermore, the dust concentration monitoring device further comprises: a dust exhaust component, the dust exhaust component comprising a second pump body 1;

[0064] The second conveying pipeline 3 , the second pump body 1 is connected to the second conveying pipeline 3 to discharge the dust less than a set threshold in the accommodating cavity 80 from the second conveying pipeline 3 .

[0065] Specifically, the dust concentration monitoring device also includes a dust exhaust component, which includes a second pump body 1 and a second conveying pipe 3 connected to the second pump body 1. The end of the second conveying pipe 3 away from the second pump body 1 is used to communicate with the accommodating cavity 80 to discharge the dust in the accommodating cavity 80.

[0066] The dust removal component can actively remove dust from the accommodating cavity 80, ensuring the cleanliness of the interior of the monitoring device 8 and reducing the impact of dust on monitoring accuracy. The second pump body 1 is connected to the accommodating cavity 80 through the second delivery pipe 3 to form an effective dust removal channel, thereby improving dust removal efficiency.

[0067] The dust exhaust component cooperates with the cleaning component (the first pump body 2 and the first conveying pipe 4) to realize two-way airflow control, that is, through the input of clean airflow and the output of dust exhaust airflow, a closed self-cleaning cycle is formed, which enhances the self-cleaning ability of the monitoring device and reduces the need for external cleaning.

[0068] Furthermore, the dust concentration monitoring device also includes: a switching component 6, the switching component 6 has a first inlet, the first inlet is connected to the outlet of the connecting pipe 7, the switching component 6 also has two first outlets, one of the two first outlets is connected to the cleaning component, and the other is connected to the second conveying pipe 3 of the dust exhaust component, so as to control the cleaning component to be connected to the accommodating cavity 80, or control the dust exhaust component to be connected to the accommodating cavity 80 according to the concentration of dust in the accommodating cavity 80.

[0069] Specifically, the switching component can select the cleaning or dust removal operation according to the real-time monitoring result of the dust concentration in the receiving cavity 80. When the dust concentration is lower than the preset threshold, the switching component controls the cleaning component to deliver clean air to the inside of the monitoring device 8 to keep the monitoring environment clean; when the dust concentration exceeds the preset threshold, the switching component controls the dust removal component to start, effectively discharging the excess dust in the receiving cavity to ensure the accuracy of the detection.

[0070] By intelligently switching between cleaning and dust removal modes, dust pollution of the internal optical components and sensors of the monitoring device 8 can be effectively avoided, and the impact of dust adsorption on the optical path can be reduced, thereby improving the detection accuracy and performance stability of the monitoring device 8.

[0071] The switching components are linked with the data processing and control system to automatically determine and execute cleaning or dust removal operations, reducing the need for manual monitoring and maintenance, lowering maintenance costs and the risk of operational errors, and improving the operating efficiency and reliability of the device.

[0072] Further, the monitoring device comprises: a monitoring housing having a receiving cavity 80;

[0073] A laser source 82, which is disposed at the bottom of the monitoring housing, and a laser emitting end of the laser source 82 faces the accommodating cavity 80;

[0074] A first optical lens 83, which is disposed in the accommodating cavity 80 and relatively far from the laser source 82;

[0075] A scattering pipe 81, which is arranged on a side of the monitoring housing away from the ventilation air path 9, and a second optical lens 84 is arranged in the scattering pipe 81;

[0076] The optical sensor 86 is disposed in the scattering pipe 81 and is relatively close to one end of the outlet of the scattering pipe 81 .

[0077] Specifically, the detection device also includes a monitoring shell having a accommodating cavity 80, and a laser source 82 arranged at the bottom of the monitoring shell, which is used to emit light into the accommodating cavity 80. A first optical lens 83 is provided on the top of the monitoring shell, and also includes a scattering pipe 81 arranged on one side of the monitoring shell, a second optical lens 84 is provided in the scattering pipe 81, and a light sensor 86 is arranged at one end relatively close to the outlet of the scattering pipe 81.

[0078] The device mainly includes a monitoring shell, which is a closed structure, and a containing cavity 80 for monitoring dust concentration is formed inside. A laser source 82 is installed at the bottom of the monitoring shell, and its function is to emit light into the containing cavity 80. After the light enters the containing cavity, it scatters with the dust, which is the basis for monitoring the dust concentration.

[0079] At the top of the monitoring shell, the device is equipped with a first optical lens 83, which optimizes the optical path to ensure that the light emitted from the laser source is transmitted in the best state. At the same time, it can also reflect or converge part of the scattered light, reduce light loss, and improve the efficiency of the optical sensor in capturing scattered light signals.

[0080] On one side of the monitoring housing, the device also includes a scattering pipe 81, which is a channel specially designed for the optical sensor to capture scattered light signals. Inside the scattering pipe 81, a second optical lens 84 is installed, the main function of which is to further focus and guide the light scattered from the accommodating cavity 80, ensuring that the light signal can be smoothly and clearly transmitted to the optical sensor.

[0081] The optical sensor 86 is located near the outlet end of the scattering pipe 81. It can capture the optical signal transmitted from the scattering pipe and convert it into an electrical signal. The electrical signal is analyzed by the data processing and control system to calculate the monitoring value of the dust concentration.

[0082] In specific implementation, the laser source 82 continuously emits light to the containing cavity 80, and the light is scattered under the action of dust particles. Part of the scattered light signal is reflected or converged by the first optical lens 83, and the other part enters the scattering pipeline 81 directly or through the focusing of the second optical lens 84 and is transmitted to the optical sensor 86. After receiving the scattered light signal, the optical sensor 86 converts it into an electrical signal related to the dust concentration. These electrical signals are received by the data processing and control system, and the monitoring value of the dust concentration is generated after calculation and processing.

[0083] The design of the monitoring housing ensures the optimization of the optical path between the laser source 82, the first optical lens 83, the second optical lens 84 and the optical sensor. At the same time, the shape and size design of the cavity 80 can ensure the uniform distribution of the airflow, which helps to improve the monitoring accuracy and reliability. Through the set cleaning and dust removal mechanism, the device can automatically maintain the cleanliness of the optical path, prevent dust from accumulating in the internal structure, ensure the accuracy of the monitoring data, reduce the need for equipment maintenance, and extend the service life.

[0084] This layout design and component configuration enable the device to monitor dust concentration efficiently and accurately. At the same time, through the automated cleaning mechanism, it ensures the cleanliness of the monitoring environment, reduces the maintenance cost of the equipment, and improves the stability and reliability of the monitoring data. It is suitable for real-time monitoring of dust concentration in a variety of industrial environments.

[0085] It also includes an electronic device 11, which is connected to the monitoring device 8 to display the monitoring results of the monitoring device 8 in real time.

[0086] According to another aspect of the present invention, a dust concentration monitoring method is also provided. The monitoring method is applicable to the above-mentioned dust concentration monitoring device. The monitoring method comprises: obtaining the real-time concentration of dust in the containing cavity of the dust concentration monitoring device;

[0087] When it is determined that the real-time concentration is greater than or equal to the set threshold, the cleaning component is controlled to communicate with the accommodating cavity, and airflow is delivered into the accommodating cavity and flows out from the ventilation air path of the monitoring device to clean the accommodating cavity.

[0088] Furthermore, the monitoring method further includes: when it is determined that the real-time concentration is less than a set threshold, controlling the dust exhaust component of the dust concentration monitoring device to communicate with the accommodating cavity and exhausting the dust in the accommodating cavity.

[0089] Specifically, the real-time concentration of dust in the receiving cavity is detected in real time. When the real-time concentration is detected to be greater than or equal to the set threshold, it is determined that the optical path in the receiving cavity may be contaminated by dust. At this time, the cleaning component is controlled to communicate with the receiving cavity, and the first air pump is turned on to deliver the clean airflow filtered by the filter component to the receiving cavity through the first delivery pipeline. The clean airflow circulates in the receiving cavity, washes off the dust particles attached to the surface of the optical element, and then flows out from the ventilation air path of the monitoring device to achieve the cleaning of the receiving cavity.

[0090] When the real-time concentration is lower than the set threshold, it proves that the optical path in the accommodating cavity is not affected by the dust. At this time, the dust removal operation can be performed normally, the dust removal component is controlled to be connected with the accommodating cavity, and the second air pump is turned on to discharge the dust particles in the accommodating cavity to the external environment through the second conveying pipe, thereby maintaining the cleanliness of the accommodating cavity and providing a clean environment for subsequent dust concentration measurements.

[0091] After the cleaning or dust removal operation is completed, the system will automatically switch back to the real-time dust concentration monitoring state and continue to measure the dust concentration in the environment. Based on the monitoring results, the system will determine whether it is necessary to start the cleaning or dust removal process again, forming a cycle process to ensure the accuracy of monitoring and the self-cleaning ability of the equipment.

[0092] This monitoring method automatically triggers the cleaning or dust removal process by setting a threshold, effectively avoiding the long-term accumulation of dust in the containment cavity, reducing the pollution of dust to the optical path, and ensuring the accuracy and reliability of the monitoring data.

[0093] The self-cleaning function ensures the cleanliness of the optical path, avoids monitoring errors caused by optical path contamination, makes the monitoring results more accurate, and improves monitoring accuracy.

[0094] Regular cleaning and dust removal reduce the wear of dust on internal components of the equipment, extend the service life of the equipment, and reduce maintenance frequency and costs.

[0095] Furthermore, after the step of discharging the dust in the receiving cavity, the step further includes:

[0096] When the cumulative dust discharge operation time reaches the set time, the step of controlling the cleaning component to communicate with the accommodating cavity is performed.

[0097] Furthermore, the real-time concentration is sent to the electronic device so that the electronic device presents the real-time concentration.

[0098] By setting the total operating time for dust exhaust, energy waste caused by excessive cleaning is avoided, and cleaning is ensured when necessary, maintaining the cleanliness of the monitoring environment and improving the accuracy and reliability of monitoring.

[0099] The automatic cleaning mechanism with set cleaning time reduces the need for human judgment and intervention. The equipment can automatically perform cleaning tasks according to preset parameters, reducing maintenance costs, especially in industrial environments with high dust concentrations.

[0100] Regular automatic cleaning can effectively prevent the long-term accumulation of dust inside the equipment, reduce equipment failures caused by dust blockage, and maintain the long-term stable operation of the monitoring equipment.

[0101] The real-time monitored dust concentration values ​​are sent to electronic equipment for display, providing operators and managers with instant environmental monitoring information, helping them to take necessary protective measures or adjust the production environment in a timely manner to ensure operational safety.

[0102] The electronic device displays real-time concentration data and supports remote monitoring. Even if the operator is not on site, the monitoring data can be obtained in real time through the network, which improves the flexibility and response speed of monitoring.
