Description

Technical Field

[0001] This application relates to the field of control system technology, and in particular to Prandtl pulse-type directional eddy current integrated dust collection device and dust collection system. Background Technology

[0002] In modern industrial production, especially in precision manufacturing and packaging, the cleanliness of product surfaces directly affects product quality and appearance. Traditional dust collection methods often rely on robotic arms or multiple fixed-position air nozzles, which not only increases equipment complexity and cost but is also inefficient, making it difficult to achieve rapid, comprehensive dust removal. Furthermore, traditional dust collection devices are energy-intensive, noisy, and poorly adaptable to different bottle types, limiting their application in diverse production needs. However, most methods fail to address how to monitor dust distribution areas to adjust eddy current parameters and how to achieve dust cleaning of different cavities using Prandtl pulse-guided eddy current components.

[0003] For example, Chinese patent application CN103823456A discloses a magnetic eddy current coupling speed control system for centrifugal load equipment, which is connected to the factory equipment at the end. It includes a field control system consisting of a motor, an ECT gearbox, a centrifugal load equipment, an air gap adjustment actuator, and a field controller; and a central control room control system consisting of the same components. The motor output is connected to the ECT gearbox, and the ECT gearbox output is connected to the factory equipment via the centrifugal load equipment. The ECT gearbox is equipped with a temperature sensor, a speed sensor, and an air gap adjustment actuator that are connected in conjunction with the ECT gearbox. The outputs of the temperature sensor, speed sensor, and air gap adjustment actuator are directly connected to the field controller to form the field control system, and connected to the central control room control system via the field instrumentation box. This system can achieve an energy saving rate of 20-60% and has broad application prospects in industries such as petrochemicals, metallurgy, power plants, mining, and cement.

[0004] For example, Chinese Patent CN102890489B discloses an installation control system for eddy current inspection equipment of heat transfer tubes in a nuclear power plant steam generator. This system includes a main control module; an opening / closing control module disconnectably connected to the main control module and used to control the opening and closing of the mechanical gripper; a locking control module connected to the main control module and used to control the locking of the mechanical gripper; a rising control module connected to the main control module and used to control the upward movement of the installation tool; a descending control module connected to the main control module and used to control the downward movement of the installation tool; an installation / unloading control module disconnectably connected to the main control module and used to control the installation and unloading of the probe door; and a control switch connected to the main control module and having three positions.

[0005] The above patents suffer from the problem described in this background: neither of the above two patents addresses how to adjust eddy current parameters by monitoring the dust distribution area and how to achieve dust cleaning of different cavities using Prandtl pulse directional eddy current guiding components. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this application provides a Prandtl pulse-type directional vortex integrated dust collection device and dust collection system.

[0007] In the first aspect, this application provides a Prandtl pulse-type directional vortex integrated dust collection system, which includes: a regional monitoring module, a pneumatic control module, a vortex processing module, and a feedback optimization module;

[0008] The area monitoring module is used to monitor the dust distribution area inside the cavity and generate control signals;

[0009] The pneumatic control module is used to receive control signals and adjust eddy current parameters.

[0010] The eddy current processing module is used to clean the dust in the cavity by using the pulsed directional eddy current generated by the Prandtl pulse directional eddy current guide component according to the adjusted eddy current parameters, and to collect and process the guided dust.

[0011] The feedback optimization module is used to re-detect whether there is still dust residue in the cavity after cleaning the dust inside the cavity. When there is dust residue, the control signal is optimized, and when there is no dust residue, the dust is collected and processed.

[0012] As an optional implementation, the strategy for monitoring the dust distribution area within the cavity includes:

[0013] The cavity region is divided according to the characteristic length of the cavity and the vortex velocity gradient;

[0014] Set up an initial dust distribution area, deploy sensors to monitor the dust concentration within the cavity area, and record the dust concentration within the cavity area according to a time series.

[0015] The dust distribution trend was obtained by analyzing the dust concentration in different time series and different cavity regions;

[0016] The initial dust distribution area is dynamically updated based on the dust distribution trend to obtain the dust distribution area inside the cavity;

[0017] Configure a dust concentration threshold, and compare the dust concentration in the dust distribution area with the dust concentration threshold to determine whether the dust concentration in the dust distribution area exceeds the standard;

[0018] If the dust concentration in the dust distribution area exceeds the standard, the eddy current adjustment mechanism is executed to generate a control signal.

[0019] As an optional implementation, the logic for dividing the cavity region includes:

[0020] Obtain the basic eddy current velocity and cavity depth, divide the cavity into several regions, and determine the relationship between the eddy current velocity and the cavity depth.

[0021] Calculate the eddy velocity corresponding to the depth of each cavity;

[0022] Configure the eddy current velocity threshold, which includes the base value and the extreme value of the eddy current velocity;

[0023] The change in eddy velocity is obtained by comparing the eddy velocity corresponding to the depth of each cavity with the eddy velocity threshold.

[0024] The cavity region is determined based on the change in eddy current velocity. The cavity region includes an upper region, a middle region, and a bottom region.

[0025] As an optional implementation, the eddy current adjustment mechanism includes:

[0026] The area where the dust concentration exceeds the standard is identified as the dust-exceeding area;

[0027] Determine the cavity area where the dust exceeds the standard;

[0028] If there is a dust exceeding the standard area in a single cavity, the eddy current intensity and direction of the eddy current in the single cavity area are adjusted to generate a control signal;

[0029] If at least two cavity areas have dust exceeding the standard, then the step-by-step adjustment logic will be executed.

[0030] As an optional implementation, the step-by-step adjustment logic includes:

[0031] Identify the location and dust concentration of areas with excessive dust levels;

[0032] Configure a dust concentration area, and guide the dust in the dust-exceeding area to the dust concentration area by adjusting the eddy current intensity and direction;

[0033] By adjusting the intensity and direction of the eddy currents, the dust in the dust-concentrated area is guided to the outside of the cavity.

[0034] The dust concentration in the dust distribution area is continuously monitored. If the dust concentration in the dust distribution area still exceeds the standard after adjustment, the eddy current adjustment mechanism is re-executed to obtain a control signal.

[0035] As an optional implementation, the pneumatic control module receives and parses the control signal, and converts the control signal into electrical parameters.

[0036] As an optional implementation, the logic for re-detecting whether dust residue still exists in the cavity includes:

[0037] Sampling points were selected within each cavity region;

[0038] Dust concentration was monitored at each sampling point;

[0039] The dust concentration at each sampling point is compared with the dust concentration threshold to determine whether the dust concentration at each sampling point exceeds the standard.

[0040] Record the number of sampling points where dust concentration exceeds the standard;

[0041] Configure a quantity threshold. If the number of sampling points with excessive dust concentration is greater than or equal to the quantity threshold, then dust residue exists in the cavity and is located in that cavity area, and the control signal is optimized.

[0042] If the number of sampling points with excessive dust concentration is less than the quantity threshold, then there is no dust residue in the cavity, and the dust is collected and processed.

[0043] Secondly, this application provides a Prandtl pulse-type directional vortex integrated dust collection device, which includes: a Prandtl pulse-type directional vortex guiding component for forming a pulse-type directional vortex in the cavity to clean the dust in the cavity.

[0044] As an optional implementation, the Prandtl pulse-directed eddy current guiding component includes a main body, an eddy current generator, and a fixed cover. The main body is fixedly connected to the eddy current generator. The eddy current generator is used to generate pulse-directed eddy currents and receive control signals generated by the dust collection system to adjust the eddy current parameters of the pulse-directed eddy currents. The fixed cover is a detachable structure used to close the main body.

[0045] Compared with existing technologies, the beneficial effects of this application are as follows: The regional monitoring module monitors the dust distribution area within the cavity and generates control signals, enabling real-time acquisition of the precise location and concentration distribution of dust, thus achieving accurate dust detection and providing necessary data support for the subsequent cleaning process; the pneumatic control module receives control signals and adjusts eddy current parameters, allowing the cleaning process to specifically target different types and levels of dust, avoiding over- or under-cleaning, improving cleaning effectiveness while saving resources; the eddy current processing module, based on the adjusted eddy current parameters, uses the Prandtl pulse-directed eddy current guiding component to generate pulse-directed eddy currents. The vortex-driven cleaning system effectively removes dust from the chamber, collecting and processing the guided dust. This efficient dust removal process ensures the dust is effectively guided and collected, preventing dust diffusion or accumulation and maintaining a clean environment. The feedback optimization module, after cleaning, re-detects any remaining dust. If residue is present, it optimizes the control signal; otherwise, it collects and processes the remaining dust, guaranteeing complete removal and preventing incomplete cleaning. By optimizing the cleaning process, it ensures optimal cleaning results, minimizing human intervention and errors. The interaction between these modules creates a closed-loop control system from monitoring to control to optimization, making the cleaning process more intelligent, efficient, and precise. It also adapts to different cleaning scenarios, reducing the need for human intervention and improving the overall reliability and stability of the dust collection system.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0054] Example 1

[0055] like Figure 2 The diagram shown illustrates the system structure of the Prandtl pulse-type directional vortex integrated dust collection system, which includes a regional monitoring module, a pneumatic control module, a vortex processing module, and a feedback optimization module.

[0056] The area monitoring module is used to monitor the dust distribution area inside the cavity and generate control signals.

[0057] Strategies for monitoring dust distribution areas within the cavity, such as Figure 3 As shown, it specifically includes:

[0058] The cavity region is divided according to the characteristic length of the cavity and the vortex velocity gradient;

[0059] It should be understood that the Prandtl pulse-directed eddy current guide component cleans dust within the cavity by generating pulse-directed eddies within the cavity. When the pulse-directed eddy current acts with an initial eddy current velocity, the eddy current velocity changes with the characteristic length of the cavity, resulting in inconsistent eddy current velocities within the cavity and thus forming different regions within the cavity. The division of the cavity regions affects the determination of the initial dust distribution area. Furthermore, the following description of the cavity mainly focuses on bottle-shaped cavities, i.e., bottles.

[0060] The logic for dividing the cavity regions includes:

[0061] Obtain the basic eddy current velocity and cavity depth, divide the cavity into several regions, and determine the relationship between the eddy current velocity and the cavity depth.

[0062] It should be understood that a bottle-shaped cavity typically consists of a bottle mouth (top), a bottle body, and a bottle bottom. The characteristic lengths of the bottle-shaped cavity include its diameter, width, and depth. Here, we need to obtain the depth of the bottle-shaped cavity, which refers to the total height of the bottle-shaped cavity, that is, the vertical height of the bottle-shaped cavity from the bottom to the top. The basic eddy current velocity refers to the initial eddy current velocity of the pulsed directional eddy current generated by the Prandtl pulsed directional eddy current guiding component. The region segment here is divided according to the uniform depth of the bottle-shaped cavity, and the division of the region segment is to better obtain the internal depth of the cavity. The internal depth of the cavity refers to the depth position inside the bottle-shaped cavity from the top to the bottom, that is, the total depth inside the bottle-shaped cavity from the top according to the depth of the region segment to different positions in the vertical height direction of the bottle-shaped cavity, until it reaches the bottom. The total depth reaching the bottom is the depth of the bottle-shaped cavity.

[0063] Experiments have shown that the eddy current velocity is not uniformly distributed at different cavity depths. It has been determined that the eddy current velocity decreases linearly with increasing cavity depth. Therefore, the functional expression relating the eddy current velocity to the cavity depth is shown below:

[0064]

[0065] In the formula, v(z) represents the eddy velocity corresponding to the depth of each cavity, v0 represents the basic eddy velocity, z represents the depth of each cavity, and d represents the cavity depth.

[0066] Starting from the top of the bottle-shaped cavity, the cavity depth is gradually increased vertically, that is, the depth of each segment is gradually increased. This yields the vortex velocity corresponding to the total depth from the top of the bottle-shaped cavity to the total depth after the segment depths are increased. In other words, the vortex velocity corresponding to the depth of each cavity is determined. This shows that the vortex velocity is stronger at the top of the bottle-shaped cavity and weaker at the bottom. Dividing the cavity into blocks helps to understand how the vortex velocity changes with the depth of the cavity, thus aiding in the subsequent division of the cavity regions.

[0067] Calculate the eddy velocity corresponding to the depth of each cavity;

[0068] The eddy current velocity corresponding to the depth of each cavity is calculated based on the function relating the eddy current velocity to the cavity depth. This provides detailed numerical data for subsequent cavity region division and eddy current velocity variation analysis, and helps to determine the variation trend of pulsed directional eddy currents within the cavity.

[0069] Configure the eddy current velocity threshold, which includes the base value and the extreme value of the eddy current velocity;

[0070] The eddy current velocity threshold configured here is used to obtain changes in eddy current velocity. When the eddy current velocity changes, it is assumed that the characteristics of the region corresponding to the depth of the cavity have changed, thereby obtaining the cavity region division results and the depth of each cavity region. The eddy current velocity base value refers to the minimum eddy current velocity of the pulse-directed eddy current during normal operation, and the eddy current velocity extreme value refers to the maximum eddy current velocity of the pulse-directed eddy current during normal operation. The configuration of the eddy current velocity threshold can help to divide the cavity region.

[0071] The change in eddy velocity is obtained by comparing the eddy velocity corresponding to the depth of each cavity with the eddy velocity threshold.

[0072] By comparing the eddy velocity corresponding to the depth of each cavity with the eddy velocity threshold, the eddy velocity variation at the corresponding location in each region can be obtained. When the eddy velocity is less than the base value, it indicates that the eddy velocity is too low. When the eddy velocity is greater than the extreme value, it indicates that the eddy velocity is too high. For example, an excessively high eddy velocity indicates that there is excessive turbulence or vortex phenomenon in that region, which is generally located in the upper part of the bottle-shaped cavity or near the bottle mouth. On the other hand, an excessively low eddy velocity indicates that the flow of pulsed directional eddy current is insufficient, which leads to dust blockage. This is generally located near the bottom of the bottle-shaped cavity, providing a basis for the subsequent division of cavity regions and adjustment of the eddy coefficient.

[0073] The cavity region is determined based on the change in eddy current velocity. The cavity region includes an upper region, a middle region, and a bottom region.

[0074] The upper region is typically located near the mouth of the bottle-shaped cavity. The vortex velocity in this region is relatively high, resulting in strong vortex impacts that cause dust to diffuse and suspend within the cavity. Therefore, it is necessary to maintain vortex stability and reduce dust suspension caused by vortex impacts. The middle region is typically located near the body of the bottle-shaped cavity. The vortex velocity in this region is moderate, uniform, and stable. Under uniform and stable vortex velocity, dust tends to concentrate and suspend in the middle region, making it difficult for dust to be carried out. Therefore, the focus in the middle region is on adjusting the vortex coefficient to remove dust. The bottom region is typically located at the bottom of the bottle-shaped cavity. The vortex velocity in this region is low, making it easy for dust to accumulate and settle. Therefore, it is necessary to adjust the vortex parameters to prevent dust accumulation and uncleanliness within the cavity.

[0075] Set up an initial dust distribution area, deploy sensors to monitor the dust concentration within the cavity area, and record the dust concentration within the cavity area according to a time series.

[0076] Here, dust is evenly distributed in different cavity areas (upper, middle and bottom areas) of the bottle-shaped cavity to set up the initial dust distribution area. When the Prandtl pulse directional eddy current guide component drives the pulse directional eddy current to clean the dust in the cavity, the initial dust distribution area will affect the movement and final distribution of the dust.

[0077] Deploying cameras and particulate matter concentration sensors to monitor dust concentration within the cavity area, especially in key areas (bottom and middle areas), and recording the dust concentration within the cavity area in a time series according to a certain time step (e.g., every minute), focusing on the changes in dust concentration at different time points and the changes in dust concentration in each cavity area, can obtain more accurate dust temporal distribution data and dust spatial distribution data.

[0078] Numerical simulation tools were used to analyze the movement of dust within the bottle-shaped cavity. Among these tools, CFX, a fluid dynamics simulation software, focuses on high-speed airflow, eddies, and particle dynamics. It is suitable for analyzing the interaction between eddies and dust, and whether the dust easily settles or is carried away by the eddies. Simulation results show that dust usually settles faster in the bottom area, while in the upper area (especially near the bottle opening), dust may be carried away by the eddies. If the eddy velocity is too high, the dust may escape from the bottle-shaped cavity with the eddies.

[0079] The principle of CFX is to create a geometric model of a bottle-shaped cavity and divide it into computational meshes. The mesh of the bottle-shaped cavity needs to be fine to ensure accurate capture of the motion of eddies and dust. Boundary conditions such as eddy inlet, outlet, and bottle-shaped cavity walls are set. Among them, the inlet eddy velocity, outlet pressure, and no-slip condition of the inner wall of the bottle-shaped cavity are key. For dust, particle size distribution, density, initial position, etc. need to be set. Using the Euler-Lagrange method, the eddies are treated as continuous media and dust as discrete matter. The motion of dust in the eddies is simulated, and the trajectory of dust under the influence of eddy drag force, gravity, etc. is calculated. An appropriate turbulence model (such as k-ε or k-ω model) is selected to simulate the turbulence characteristics of the airflow. The motion of dust in the bottle-shaped cavity is simulated, especially how dust is suspended or carried away by the eddies. Through the results of CFX calculations, the velocity distribution, settling velocity, and concentration distribution of dust in the bottle-shaped cavity, as well as the dust motion in the bottle mouth and bottom area, are observed to analyze whether the eddies are sufficient to carry away the dust.

[0080] The dust distribution trend was obtained by analyzing the dust concentration in different time series and different cavity regions;

[0081] When cleaning dust in a vortex, it is necessary to monitor whether the dust in the upper area diffuses into the middle and bottom areas, and the dust concentration in the corresponding areas; monitor whether the dust accumulates in the bottom area, and the dust concentration in the corresponding area; and monitor whether the dust is suspended in the middle area, and the dust concentration in the corresponding area. This will allow us to obtain the dust distribution trend in different time series and different cavity areas, and observe the movement and accumulation of dust during the vortex cleaning process.

[0082] The initial dust distribution area is dynamically updated based on the dust distribution trend to obtain the dust distribution area inside the cavity;

[0083] During the CFX simulation, the distribution of dust changes over time, and the dust concentration and movement trend change with factors such as eddy current velocity, different cavity regions, dust settling and diffusion. Therefore, it is necessary to dynamically update the initial dust distribution area based on the dust distribution trend under different time series and different cavity regions to obtain a more accurate dust distribution area. Dynamically updating the initial dust distribution area can more realistically reflect the dust distribution in the cavity. By monitoring the changes in dust concentration in different regions, the eddy current coefficient can be adjusted in a timely manner to achieve more effective cleaning.

[0084] Specifically, if the dust concentration in the upper region reaches a certain threshold in a certain time series, and this dust begins to diffuse into the middle region, then the initial dust distribution in the middle region can be dynamically updated to include the diffused dust from the upper region. If the dust concentration in the middle region is too high, and the dust will diffuse into the bottom region in the next time series, then the initial dust distribution in the bottom region needs to be updated. Alternatively, if the dust in the middle region cannot be guided to the outside of the bottle-shaped cavity by the current pulsed directional eddy current (at which point the initial dust distribution in the middle region needs to be updated), then if the dust in the bottom region accumulates to exceed a certain threshold, then the initial dust distribution in the bottom region will be updated to a higher dust concentration value, resulting in a dust settling effect.

[0085] Configure a dust concentration threshold, and compare the dust concentration in the dust distribution area with the dust concentration threshold to determine whether the dust concentration in the dust distribution area exceeds the standard;

[0086] If the dust concentration in the dust distribution area exceeds the standard, the eddy current adjustment mechanism is executed to generate a control signal.

[0087] During the pulsed vortex cleaning process, the dust concentration in the dust distribution area will change with the time series. Therefore, it is necessary to configure a dust concentration threshold to compare and judge whether the dust concentration in the dust distribution area exceeds the standard. When the dust concentration in the dust distribution area is greater than or equal to the dust concentration threshold, it is judged that the dust concentration in the dust distribution area exceeds the standard; otherwise, it does not exceed the standard. When the dust concentration in the dust distribution area does not exceed the standard, there is no need to adjust the vortex and keep the vortex stable to avoid dust suddenly accumulating in a certain time series.

[0088] When the dust concentration in the dust distribution area exceeds the standard, the vortex needs to be adjusted. Considering that the movement and accumulation of dust under the influence of the vortex will affect the dust concentration in the dust distribution area, for example, when the pulse directional vortex is cleaning the cavity, dust will move from the upper area to the middle area, causing dust diffusion, or from the middle area to the bottom area, causing dust accumulation, thus changing the dust concentration in the dust distribution area, it is necessary to implement the vortex adjustment mechanism to effectively cope with the changes in dust concentration in different dust distribution areas, avoid excessive dust accumulation in a certain area of ​​the cavity, ensure that the accumulated dust can be cleaned, and achieve flexible control of the dust collection system.

[0089] Eddy current adjustment mechanism such as Figure 4 As shown, it specifically includes:

[0090] The dust distribution area where the dust concentration exceeds the standard is identified as the dust exceeding the standard area. The cavity area where the dust exceeding the standard area is located is determined. If a single cavity area has a dust exceeding the standard area, the eddy current intensity and eddy current direction of the single cavity area are adjusted to generate a control signal.

[0091] It should be understood that the dust distribution area with excessive dust concentration is defined as the dust exceeding the standard area. Then it is necessary to determine which cavity area the dust exceeding the standard area is located in, because the movement and accumulation of dust are different in each cavity area. Furthermore, the situation is different if the dust exceeding the standard area is located in one cavity area, or in two or more cavity areas at the same time. Targeted control of eddy current intensity and direction is required to achieve efficient dust removal and collection.

[0092] Specifically, if the dust-exceeding area is located within a single cavity, the intensity and direction of the eddies within that cavity need to be adjusted to generate control signals. For example, when the dust-exceeding area is in the upper region, the eddy current intensity needs to be reduced. This is because the eddy current velocity is higher in the upper region, resulting in a stronger eddy current impact that makes dust within the cavity more prone to diffusion and suspension. Appropriately reducing the eddy current intensity can reduce the excessive impact of the eddies, preventing dust from migrating in large quantities to the bottom region under the influence of the eddies, thereby stabilizing the dust distribution and preventing a rapid increase in dust concentration in the bottom region due to excessive dust migration. At the same time, the eddy current direction is changed to concentrate the eddies in the upper region. This is to reduce the tendency of the eddies to diffuse from the upper region to the bottom region. In this way, while reducing the overall impact, a certain intensity of eddies can be maintained in the upper region, allowing the eddies to both control the degree of dust suspension and continue to entrain and clean up dust with the remaining eddy current force, ensuring the cleaning effect of the upper region itself. The control signals generated at this time include instructions to reduce the eddy current intensity and adjust the eddy current generator to make the eddies converge in the upper region.

[0093] When the dust exceeding the standard area is located in the central region, it is necessary to increase the eddy current intensity. This is because the eddy current velocity in the central region is usually moderate and relatively stable. In this environment, dust is concentrated and suspended, making it difficult to be carried out. Increasing the eddy current intensity breaks the original relatively balanced dust suspension state, enhances the fluidity of the dust, and causes the accumulated dust to move with the eddy current, making it easier to be discharged later. At the same time, the direction of the eddy current is adjusted to strengthen the guidance of the eddy current to the upper region or to spread outward. On the one hand, it guides the dust to flow to the upper region where it is easier to be discharged. With the help of the relatively strong eddy current in the upper region, the dust is accelerated to leave the central region. On the other hand, the adjustment of the outward spreading eddy current can prevent the dust from further accumulating in the central region and avoid excessive dust flowing to the bottom region, causing secondary accumulation. The control signals generated at this time include instructions to increase the eddy current intensity and adjust the eddy current generator to make the eddy current spread to the upper region or outward.

[0094] When the dust exceeding the standard area is located at the bottom, the eddy current intensity needs to be increased. This is because the eddy current velocity and intensity are relatively low at the bottom, making it easy for dust to accumulate and settle. Increasing the eddy current intensity at the bottom provides sufficient power for the deposited dust, allowing it to overcome gravity and friction, resuspend, and move with the eddy current, preventing further accumulation. At the same time, the eddy current direction is adjusted to make it more vertical or flow towards the bottom. Vertical eddies are beneficial for directly impacting the accumulated dust, loosening and lifting it. Eddies guided towards the bottom prevent suspended dust from being easily carried out to other cavity areas, reducing interference with other clean cavity areas, while ensuring that the dust in the bottom area is fully cleaned under the enhanced eddy current action. At this time, the control signals include instructions to increase the eddy current intensity and adjust the eddy current generator to make the eddy current more vertical or flow towards the bottom.

[0095] If at least two cavity areas have dust exceeding the standard, then the step-by-step adjustment logic will be executed;

[0096] Specifically, when there are areas with excessive dust in at least two chamber areas, the adjustment of eddy current intensity and direction needs to consider how to avoid cross-influence of dust between chamber areas and mutual interference of eddies, and maintain the overall stability and efficient operation of the dust collection system according to the step-by-step adjustment logic.

[0097] If multiple chamber areas have dust exceeding the standard, it can lead to cross-influence of dust. For example, pulsed directional eddy currents can carry dust from one chamber area to another, causing dust to accumulate in multiple chamber areas and thus exacerbating the problem of dust exceeding the standard in the areas with excessive dust.

[0098] This requires effective coordinated control of the vortex intensity and direction within multiple cavity areas, and guiding the dust from areas with excessive dust levels to first accumulate in a specific area before finally being discharged outside the cavity for cleaning. This necessitates identifying the spatial distribution of dust concentration and adjusting the vortex intensity and direction step by step to ensure that the dust is effectively cleaned and collected.

[0099] The step-by-step adjustment logic includes:

[0100] The system identifies the location and concentration of dust exceeding the standard, configures a dust concentration area, and guides the dust in the dust exceeding the standard area to the dust concentration area by adjusting the eddy current intensity and direction. Then, it guides the dust in the dust concentration area to the outside of the cavity by adjusting the eddy current intensity and direction. The dust concentration in the dust distribution area is continuously monitored. If the dust concentration in the dust distribution area still exceeds the standard after adjustment, the eddy current adjustment mechanism is re-executed to obtain a control signal.

[0101] The location of areas with excessive dust is determined in real time by a camera, and the dust concentration in these areas is identified by a particulate matter concentration sensor. Within these areas, the goal of the vortex is to guide dust from multiple areas to a specific area for concentrated accumulation. This specific area is defined as the dust concentration area. The dust concentration area can effectively gather dust from other cavity areas. Here, the dust concentration area can be the area near the cavity outlet (bottle mouth).

[0102] Dust from multiple areas exceeding dust standards is guided to a dust concentration area. By increasing the intensity of the eddy currents, the inertia and viscous resistance of the dust are overcome, ensuring that the dust can be effectively carried away from the dust concentration area and discharged from the cavity outlet to the outside of the cavity. This avoids dust retention or dispersion due to insufficient eddy current intensity. At the same time, based on the location of the dust concentration area and the location of each dust-exceeding area, the eddy current direction is uniformly planned to ensure that the eddies generated in each cavity area guide the dust directly to the dust concentration area in a unified eddy current direction, avoiding phenomena such as eddy current reversal and crossing. For example, a strong eddy current is added in the dust-exceeding area to drive the dust towards the dust concentration area.

[0103] Once the dust has been successfully concentrated in the dust concentration area, the goal is to guide the dust out of the cavity smoothly by adjusting the intensity and direction of the eddy current, thereby completing the cleaning process.

[0104] Specifically, the vortex intensity is increased between the dust concentration area and the cavity outlet to accelerate the discharge of dust through the cavity outlet, ensuring that dust does not accumulate and block near the cavity outlet. At the same time, the direction of the vortex inside the cavity is adjusted so that the dust that has gathered in the dust concentration area can flow directly and smoothly to the cavity outlet, and the vortex is made more vertical or diffused towards the cavity outlet, eliminating phenomena such as dust backflow and swirling at the outlet, and ensuring efficient dust discharge.

[0105] When guiding dust out of the cavity, it is necessary to continuously monitor the dust distribution area, the dust exceeding the standard area, the dust concentration area, and the dust concentration at the cavity outlet to determine whether the dust still exceeds the standard. If the dust concentration in the dust distribution area still exceeds the standard after adjusting the vortex intensity and vortex direction, the vortex adjustment mechanism needs to be re-executed to ensure that the dust in the cavity can be cleaned.

[0106] By individually identifying and adjusting the distribution of various situations where dust concentration exceeds the standard, the dust distribution in multiple cavity areas can be effectively managed, thereby optimizing the cleaning process.

[0107] The pneumatic control module is used to receive control signals and adjust eddy current parameters.

[0108] The pneumatic control module has a signal receiving function and is compatible with multiple communication protocols, such as the common CAN bus, so as to quickly and stably receive control signals generated by the area monitoring module. The received control signals include eddy current intensity adjustment commands and eddy current direction adjustment commands. These commands are parsed and converted into electrical parameters that can be recognized by the Prandtl pulse directional eddy current guide component.

[0109] After the adjustment command for the eddy current intensity is parsed, the eddy current generator in the Prandtl pulse directional eddy current guide component is gradually fine-tuned. For example, when the dust exceeding the standard area is in the bottom area, the adjustment command for the eddy current intensity is to increase the eddy current intensity. After receiving the command, the eddy current generator gradually increases the eddy current flow rate, so that the eddy current flowing into the eddy current generator gradually increases, thereby gradually increasing the eddy current intensity.

[0110] After the adjustment command for the eddy current direction is parsed, the eddy current generator in the Prandtl pulse directional eddy current guide component is gradually fine-tuned. For example, when the dust exceeding the standard area is in the bottom area, the adjustment command for the eddy current direction is to adjust the eddy current generator to make the eddy current more vertical or flow towards the bottom area. After receiving the command, the eddy current generator changes the flow direction of the eddy current in the eddy current generator channel, thereby guiding the eddy current to rotate in the vertical direction.

[0111] Throughout the process of adjusting the eddy current parameters, it is necessary to continuously monitor whether the adjustment of the eddy current intensity and direction has achieved the expected effect, that is, whether the dust concentration in the dust distribution area exceeds the standard. If the expected effect is not achieved, the eddy current flow rate and the flow direction of the eddy current in the eddy current generator channel are automatically fine-tuned, and repeated attempts are made until precise control is achieved.

[0112] The eddy current treatment module is used to clean the dust in the cavity by using the pulsed eddy current generated by the Prandtl pulsed eddy current guide component according to the adjusted eddy current parameters, and to collect and treat the guided dust.

[0113] Based on the information on dust distribution areas and dust exceeding standards fed back by the regional monitoring module, after adjusting the vortex parameters through the pneumatic control module, the Prandtl pulse directional vortex guiding component is activated, thereby generating a pulse directional vortex with a certain intensity. The vortex first acts on the upper region of the cavity. Since the vortex velocity in the upper region is relatively large, the impact force generated is sufficient to blow away or shake off the dust adhering to the surface of the upper region of the cavity, causing it to enter a suspended state.

[0114] As the vortex continues to flow towards the bottom region, the vortex velocity varies according to a pre-set gradient at different depths within the cavity, ensuring that sufficient force is generated at each level of the cavity region to loosen the dust completely. For example, the vortex velocity is higher in the upper region, but as the depth of the cavity increases, the vortex velocity gradually decreases, but always maintains a force that can keep the dust suspended and push it towards the bottom region.

[0115] When an area with excessive dust is detected within the cavity, the direction of the vortex is adjusted to create a directional vortex field within the bottle-shaped cavity. This directs more vortex flow to the area with excessive dust, loosening the dust on its surface and moving it to the dust concentration area. Then, the vortex intensity is appropriately increased to enhance the pushing force on the dust, causing it to quickly converge towards the cavity outlet (the mouth of the bottle-shaped cavity). This achieves dust cleaning within the cavity without contacting the internal surface of the bottle-shaped cavity, avoiding potential damage or secondary pollution from physical contact.

[0116] The dust, guided by the vortex, will eventually be pushed toward the mouth of the bottle-shaped cavity to be guided out of the cavity until it is guided into a dust collector. This dust collector should have sufficient filtration accuracy to collect and process the guided dust to ensure that the dust particles do not flow back into the air or into the bottle-shaped cavity.

[0117] The feedback optimization module is used to re-detect whether there is still dust residue in the cavity after cleaning. If there is dust residue, the control signal is optimized; if there is no dust residue, the dust is collected and processed.

[0118] The logic for re-checking whether dust residue still exists inside the cavity includes:

[0119] Sampling points are selected within each cavity area. Dust concentration is monitored at each sampling point, and the dust concentration at each sampling point is compared with the dust concentration threshold to determine whether the dust concentration at each sampling point exceeds the standard. The number of sampling points with excessive dust concentration is recorded, and a number threshold is configured. If the number of sampling points with excessive dust concentration is greater than or equal to the number threshold, then there is dust residue in the cavity and it is located in that cavity area. The control signal is then optimized.

[0120] If the number of sampling points with excessive dust concentration is less than the quantity threshold, then there is no dust residue in the cavity, and the dust is collected and processed.

[0121] Sampling points are selected within each cavity area according to the geometric distribution of the bottle-shaped cavity, and detection is carried out according to a reasonable monitoring cycle. For example, the dust in the bottle-shaped cavity is re-detected every ten minutes. Taking the detection of 7 points as an example, the sampling points are preferentially set at angles where dust is easy to accumulate, places with large slope changes, and the turning points of the bottle mouth. For example, sampling points are selected at the turning points of the bottle mouth in the upper area, 4 sampling points are selected at the connection with the upper area in the middle area, and 3 sampling points are selected in the middle section of the bottle-shaped cavity. In the bottom area, 4 sampling points are selected at the connection with the middle area, and 3 sampling points are selected at the concave bottom of the bottle-shaped cavity, making the sampling points more targeted.

[0122] Dust concentration is monitored at each sampling point using a particulate matter concentration sensor. The principle of the particulate matter concentration sensor is to transmit an optical signal to the sampling point, utilize the absorption and scattering characteristics of light by dust to change the optical signal, and then transmit the returned optical signal back to the receiving end for analysis to determine the dust concentration at each sampling point. The dust concentration at each sampling point is then compared with a dust concentration threshold to determine whether the dust concentration at each sampling point exceeds the standard. When the dust concentration at a sampling point is greater than or equal to the dust concentration threshold, it indicates that the dust concentration at that sampling point exceeds the standard.

[0123] The monitoring results of each sampling point are recorded, and the number of sampling points with excessive dust concentration is counted. The cavity area corresponding to the sampling points with excessive dust concentration is recorded simultaneously. A threshold for the number of points is configured. Specifically, if more than 3 out of 7 sampling points (including 3) in each cavity area show excessive dust concentration, it is determined that dust residue exists in the cavity. Furthermore, if the location of the dust residue is determined to be within that cavity area, then the control signal needs to be optimized. Detailed residue information is transmitted to the area monitoring module via the CAN bus. The information retained includes the location of the cavity area where dust residue is located, the distribution of sampling points with dust residue, and the corresponding dust concentration values. The causes of dust residue are analyzed, such as insufficient eddy current intensity, deviation of eddy current direction, or unreasonable setting of the initial dust distribution area. Based on the analysis results, the eddy current adjustment mechanism is re-optimized, including adjusting the eddy current intensity and direction, or reconfiguring the initial dust distribution area, and corresponding control signals are generated and sequentially transmitted to the pneumatic control module and the eddy current processing module, driving these two modules to operate according to the new eddy current parameters to clean the dust in the bottle-shaped cavity again.

[0124] If only one or two out of the seven sampling points monitored in each cavity area, or if no sampling points are found to have dust concentrations exceeding the standard, it is determined that there is no dust residue in the cavity. No adjustments need to be made temporarily, and monitoring can continue for the next monitoring cycle. The dust collector should be cleaned regularly to ensure dust collection efficiency and timely and effective treatment.

[0125] Example 2

[0126] like Figure 1 The diagram shown illustrates the structural design of a Prandtl pulse-type directional eddy current integrated dust collection device, as provided in this application embodiment. The device includes:

[0127] Prandtl pulse-directed eddy current guide member is used to form pulse-directed eddy currents within cavity 4 to clean dust within cavity 4.

[0128] The Prandtl pulse-directed eddy current guide component includes a main body 1, an eddy current generator 2, and a fixed cover 3. The main body 1 is fixedly connected to the eddy current generator 2. The eddy current generator 2 is used to generate pulse-directed eddy currents and receive control signals generated by the dust collection system to adjust the eddy current parameters of the pulse-directed eddy currents. The fixed cover 3 is a detachable structure used to close the main body 1.

[0129] The function of the Prandtl pulse directional vortex guide component is to generate a tornado-like pulse directional vortex through the vortex generator 2 to clean the dust inside the cavity 4. The cavity 4 is a bottle-shaped cavity, and the fixed cover 3 can be easily disassembled to replace different cavities 4 for cleaning. It can effectively solve the problem of dust and foreign matter accumulation caused by structural dead corners in the cavity 4 and the inability to remove them, and can efficiently remove the dust adsorbed inside and outside the cavity 4.

[0130] The cavity 4 needs to be placed around the vortex generator 2, and the vortex generator 2 is located inside the cavity 4 through the bottle mouth of the cavity 4, so that the pulsed directional vortex generated by the vortex generator 2 can effectively act on the dust inside the cavity 4. In order to improve the cleaning effect of the cavity 4, the pulsed directional vortex generated by the vortex generator 2 should be able to generate sufficient power and range to cover all areas inside the cavity 4.

[0131] The eddy current generator 2 needs to be fixedly connected to the main body 1 to ensure that the eddy current generator 2 does not shift or vibrate during operation, thereby affecting the generation and propagation of the pulse directional eddy current. The main body 1 can provide a stable platform so that the eddy current generator 2 is always in its optimal working state. Moreover, the eddy current generator 2 can receive the control signal generated by the dust collection system, thereby adjusting the eddy current parameters of the pulse directional eddy current. The eddy current parameters include eddy current intensity and eddy current direction, so as to clean the dust in the cavity 4 and prevent the dust from accumulating into a dust distribution area when the pulse directional eddy current is applied.

[0132] The fixed cover 3 is a detachable structure used to close the main body 1, ensuring airtightness during the cleaning process of the cavity 4, and preventing leakage of the pulse directional eddy current of the eddy current generator 2 or interference from the external environment during the cleaning process. Usually, the fixed cover 3 can simultaneously fix the cavity 4 when closing the main body 1 to prevent the cavity 4 from loosening under the action of the pulse directional eddy current. The detachable structure design makes it easy to replace different cavities 4 for dust cleaning in different cavities 4, which improves the flexibility and application range of the Prandtl pulse directional eddy current guide component and enables directional cleaning of different cavities 4.

[0133] The main body 1 is the foundation of the Prandtl pulse directional eddy current guiding component, providing stable support. With the eddy current generator 2 fixedly connected to the main body 1, the cavity 4 can be placed in the groove on the main body 1 to ensure the fixed position of the cavity 4, so that the cavity 4 can be placed stably and effectively docked with the eddy current generator 2, so as to avoid the vibration of the cavity 4 when the eddy current generator 2 generates pulse directional eddy current, thereby affecting the cleaning effect of the cavity 4.

[0134] The beneficial effects of this device:

[0135] Utilizing pulsed directional eddy current technology, full-surface dust removal from the inside out can be achieved without complex mechanical structures; the automated process of this device can complete dust removal in a short time; adjustable optimization and dust area monitoring make it suitable for bottles of different shapes and sizes; through the ingenious design between pulsed directional eddy current and device structure, operating noise is significantly reduced and the service life of the dust collection device is improved.
