Description

Technical Field

[0001] This application relates to the technical field of control systems, and particularly to a Prandtl pulsed directional eddy current integrated dust removal and collection device and a dust removal and collection system. Background Art

[0002] In modern industrial production, especially in the precision manufacturing and packaging industries, the cleanliness of the product surface directly affects the product quality and appearance. Traditional dust removal and collection methods mostly rely on robotic arms or multiple fixed-position air-blowing nozzles, which not only increase the complexity and cost of the equipment, but also have low efficiency and are difficult to achieve rapid and all-round dust removal. In addition, traditional dust removal and collection devices have high energy consumption, high noise, and poor adaptability to different bottle types, restricting their application in diverse production requirements. However, most of them do not solve the problem of how to adjust eddy current parameters by monitoring the dust distribution area and achieve dust cleaning of different cavities through Prandtl pulsed directional eddy current guiding components.

[0003] For example, the Chinese patent application with the publication number CN103823456A discloses a magnetic eddy current coupling variable speed control system for a centrifugal load device, with the end connected to factory equipment. It includes a field control system composed of a motor, an ECT transmission, a centrifugal load device, an air gap adjustment actuator, and a field controller, as well as a central control room control system composed of a motor, an ECT transmission, a centrifugal load device, an air gap adjustment actuator, a field instrument electrical box, and a central control room. The output end of the motor is connected to the ECT transmission, and the output end of the ECT transmission is connected to the factory equipment through the centrifugal load device. The ECT transmission is equipped with a temperature sensor, a speed sensor, and an air gap adjustment actuator that are connected to the ECT transmission. The output ends of the temperature sensor, the speed sensor, and the air gap adjustment actuator are directly connected to the field controller to form a field control system and are connected to the central control room through the field instrument electrical box to form a central control room control system. The power saving rate of this system can reach 20–60%, and it has very broad application prospects in industries such as petrochemical, metallurgy, power plants, mines, and cement.

[0004] For example, the Chinese patent with the authorization announcement number CN102890489B discloses an installation control system for an eddy current inspection device for heat transfer tubes of a nuclear power plant steam generator. It includes a total control module; an opening / closing control module that is disconnectably connected to the total control module and is used to control the opening and closing of a mechanical gripper; a locking control module that is connected to the total control module and is used to control the locking of the mechanical gripper; a rising control module that is connected to the total control module and is used to control the upward movement of an installation tool; a descending control module that is connected to the total control module and is used to control the downward movement of the installation tool; an installation / unloading control module that is disconnectably connected to the total control module and is used to control the installation and unloading of a probe door; and a control switch with three gears that is connected to the total control module.

[0005] The above patents have the problems raised in this background art: The above two patents do not solve the problems of how to adjust the eddy current parameters by monitoring the dust distribution area and how to clean the dust in different cavities through the Prandtl pulse directional eddy current guiding component. Summary of the Invention

[0053] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0054] Embodiment 1

[0055] As Figure 2 shown, the system structure diagram of the Prandtl pulse-type directional eddy current integrated dust removal and collection system provided by the embodiment of the present application is shown. The system includes a regional monitoring module, a pneumatic control module, an eddy current processing module and a feedback optimization module.

[0056] The regional monitoring module is used to monitor the dust distribution area in the cavity and generate a control signal.

[0057] The strategy for monitoring the dust distribution area in the cavity is as Figure 3 shown, and specifically includes:

[0058] Dividing the cavity area according to the characteristic length of the cavity and the eddy current velocity gradient;

[0059] It should be understood that the Prandtl pulse directional eddy current guiding member cleans the dust in the cavity by generating a pulse directional eddy current in the cavity. When the pulse directional eddy current acts at an initial eddy current velocity, as the characteristic length of the cavity changes, the eddy current velocity will change, resulting in inconsistent eddy current velocities acting in the cavity, thus forming different regions in the cavity. The division of the cavity area here affects the determination of the subsequent initial dust distribution area; at the same time, the following introduction to the cavity is mainly about the bottle-shaped cavity, that is, the bottle.

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

[0061] Obtaining the basic eddy current velocity and the cavity depth, dividing the cavity into several area segments, and determining the relationship between the eddy current velocity and the inner depth of the cavity;

[0062] It should be understood that the bottle cavity is generally composed of a bottle mouth (top), a bottle body, and a bottle bottom (bottom). The characteristic length of the bottle cavity includes the diameter, width, and depth of the bottle cavity. Here, what needs to be obtained is the depth of the bottle cavity. The depth of the bottle cavity refers to the total height of the bottle cavity, that is, the vertical height of the bottle 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 pulse directional eddy current guiding member. The regional segments here are divided according to the uniform depth of the bottle cavity, and the division of the regional segments is to better obtain the internal depth of the cavity. The internal depth of the cavity refers to the depth position inside the bottle cavity from the top to the bottom, that is, the total depth at different positions in the vertical height direction of the bottle cavity from the top according to the depth of the regional segments until it reaches the bottom, and the total depth reaching the bottom is the depth of the bottle cavity.

[0063] Experiments have shown that on different internal depths of the cavity, the eddy current velocity is usually not uniformly distributed. It is determined that the eddy current velocity decreases linearly with the increase of the internal depth of the cavity. Thus, the functional expression of the relationship between the eddy current velocity and the internal depth of the cavity is as follows:

[0064]

[0065] In the formula, v(z) represents the eddy current velocity corresponding to each internal depth of the cavity, v 0 represents the basic eddy current velocity, z represents each internal depth of the cavity, and d represents the cavity depth.

[0066] Starting from the top of the bottle cavity, gradually increase the cavity depth in the vertical direction of the bottle cavity, that is, gradually increase the depth of the regional segments, so as to obtain the eddy current velocity corresponding to the total depth from the top of the bottle cavity to the depth after increasing the regional segments, that is, the eddy current velocity corresponding to each internal depth of the cavity. In this way, it can be obtained that the eddy current velocity at the top of the bottle cavity is stronger, while the eddy current velocity at the bottom of the bottle cavity is weaker. The division of the regional blocks can help understand the change of the eddy current velocity with the internal depth of the cavity, thus helping the subsequent division of the cavity area.

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

[0068] Calculating the eddy current velocity corresponding to each internal depth of the cavity according to the function of the relationship between the eddy current velocity and the internal depth of the cavity can provide detailed numerical data for the subsequent division of the cavity area and the analysis of the change of the eddy current velocity, and help judge the change trend of the pulsed directional eddy current in the cavity.

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

[0070] The eddy current velocity threshold configured here is to obtain the change in the eddy current velocity. When the eddy current velocity changes, it is considered that the characteristics at the corresponding region segment of the depth in the cavity have changed, so as to obtain the division result of the cavity region and the depth of each cavity region; while the eddy current velocity base value refers to the minimum eddy current velocity when the pulsed directional eddy current is working normally, and the eddy current velocity extreme value refers to the maximum eddy current velocity when the pulsed directional eddy current is working normally. The configuration of the eddy current velocity threshold can help divide the cavity region.

[0071] Compare the eddy current velocity corresponding to the depth of each cavity with the eddy current velocity threshold to obtain the change in the eddy current velocity;

[0072] By comparing the eddy current velocity corresponding to the depth of each cavity with the eddy current velocity threshold, the change in the eddy current velocity at the corresponding position of each region segment can be obtained. When the eddy current velocity is less than the eddy current velocity base value, it means that the eddy current velocity is too low. When the eddy current velocity is greater than the eddy current velocity extreme value, it means that the eddy current velocity is too high. For example, a too high eddy current velocity indicates that there is excessive turbulence or vortex phenomenon in this region segment, which is generally located in the upper part of the bottle cavity or near the bottle mouth, while a too low eddy current velocity indicates insufficient flow of the pulsed directional eddy current, resulting in dust blockage, which is generally located near the bottom of the bottle cavity, providing a basis for the subsequent division of the cavity region and the adjustment of the eddy current coefficient.

[0073] Determine the cavity region according to the change in the eddy current velocity. The cavity region includes the upper region, the middle region and the bottom region;

[0074] The upper region is usually located near the bottle mouth of the bottle cavity. The eddy current velocity in this upper region is relatively fast, thus forming a strong eddy current impact to cause the dust in the cavity to diffuse and suspend. Therefore, it is necessary to maintain the stability of the eddy current and reduce the dust suspension caused by the eddy current impact; the middle region is usually located near the bottle body of the bottle cavity. The eddy current velocity in this middle region is moderate, uniform and stable. Under the uniform and stable eddy current velocity, the dust will form a concentrated suspension in the middle region, resulting in the dust suspension and not being easily carried out. Therefore, the middle region will focus on considering how to carry out the dust by adjusting the eddy current coefficient; the bottom region is usually located at the bottom of the bottle cavity. The eddy current velocity in this bottom region is relatively low, which easily causes the dust to accumulate and form sedimentation. Therefore, it is necessary to adjust the eddy current parameters to avoid the cavity being unclean due to dust accumulation.

[0075] Set the initial dust distribution region, deploy sensors to monitor the dust concentration in the cavity region, and record the dust concentration in the cavity region according to the time series;

[0076] Dust will be evenly distributed in different cavity regions (upper region, middle region, and bottom region) of the bottle cavity to set it as the initial dust distribution region. When the Prandtl pulse directional eddy guiding component drives the pulsed directional eddy to clean the dust in the cavity, the initial dust distribution region will affect the movement and final distribution of the dust.

[0077] Deploy cameras and particulate matter concentration sensors to monitor the dust concentration in the cavity region, especially in key regions (bottom region and middle region), and record the time series of the dust concentration in the cavity region according to a certain time step (such as every minute). By paying attention to the changes in the dust concentration at different time points and the changes in the dust concentration in each cavity region, more accurate dust time distribution data and dust spatial distribution data can be obtained.

[0078] Use numerical simulation tools to analyze the movement of dust in the bottle cavity. Numerical simulation tools such as CFX, this computational fluid dynamics simulation software focuses on fields such as high-speed airflow, eddy currents, and particle dynamics, and is suitable for analyzing the interaction between eddy currents and dust, whether it is easy to settle or be carried away by eddy currents. The simulation results prove that dust usually settles faster in the bottom region, while in the upper region (especially near the bottle mouth), dust may be carried away by eddy currents. If the eddy current speed is too high, dust may escape from the bottle cavity along with the eddy current.

[0079] The principle of CFX is to create a geometric model of the bottle cavity and divide the computational grid. The grid division of the bottle cavity should be fine to ensure that the movement of eddy currents and dust can be accurately captured; set boundary conditions such as the eddy current inlet, outlet, and the wall of the bottle cavity. Among them, the inlet eddy current speed, outlet pressure, and the no-slip condition of the inner wall of the bottle cavity are crucial. For dust, it is necessary to set the particle size distribution, density, initial position, etc.; use the Euler-Lagrange method, regard the eddy current as a continuous medium, and the dust as a discrete substance, simulate the movement of dust in the eddy current, calculate the movement trajectory of dust affected by the drag force, gravity, etc. of the eddy current, and select a suitable turbulence model (such as the k-ε or k-ω model) to simulate the turbulence characteristics of the airflow; simulate the movement of dust in the bottle cavity, especially how dust is suspended or carried away under the action of eddy currents; through the results calculated by CFX, observe the velocity distribution, settling velocity, and concentration distribution of dust in the bottle cavity, as well as the movement of dust in the bottle mouth and bottom regions, and analyze whether the eddy current is sufficient to carry away the dust.

[0080] Analyze the dust concentration in different time series and different cavity regions to obtain the dust distribution trend;

[0081] When eddy current is used to clean dust, it is necessary to monitor whether the dust in the upper area spreads to the middle area and the bottom area, as well as the dust concentration in the corresponding areas; monitor whether dust accumulates in the bottom area and the dust concentration in the corresponding area; at the same time, monitor whether dust forms suspension in the middle area and the dust concentration in the corresponding area, so as to obtain the dust distribution trend in different time series and different cavity areas, and observe the movement and accumulation of dust during the eddy current cleaning process.

[0082] Dynamically update the initial dust distribution area according to the dust distribution trend to obtain the dust distribution area in the cavity;

[0083] During the simulation process of CFX, the dust distribution will change with the time series, and the dust concentration and movement trend will change due to factors such as eddy current speed, different cavity areas, dust settlement and diffusion. Therefore, it is necessary to dynamically update the initial dust distribution area according to the dust distribution trend in different time series and different cavity areas, so as 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 change of dust concentration in different areas, the eddy current coefficient can be adjusted in time to achieve more effective cleaning.

[0084] Specifically, if the dust concentration in the upper area reaches a certain threshold at a certain time series and the dust begins to spread to the middle area, then the initial dust distribution in the middle area can be dynamically updated to include the diffused dust from the upper area; if the dust concentration in the middle area is too high and the dust will spread to the bottom area in the next time series, at this time, the initial dust distribution in the bottom area needs to be updated, or the dust in the middle area cannot be guided to the outside of the bottle cavity by the current pulsed directional eddy current (in this case, the initial dust distribution in the middle area needs to be updated); if the dust accumulation in the bottom area exceeds a certain threshold, then the initial dust distribution in the bottom area will be updated to a higher dust concentration value, resulting in a dust settlement effect.

[0085] Configure the 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, execute the eddy current adjustment mechanism to generate a control signal.

[0087] During the process of cleaning the cavity with pulsed directional eddy current, as the time series changes, the dust concentration within the dust distribution area also varies. Therefore, it is necessary to configure a dust concentration threshold to compare and determine whether the dust concentration within the dust distribution area exceeds the standard. When the dust concentration within the dust distribution area is greater than or equal to the dust concentration threshold, it is determined that the dust concentration within the dust distribution area exceeds the standard; otherwise, it does not. When the dust concentration within the dust distribution area does not exceed the standard, there is no need to adjust the eddy current, and the eddy current is maintained stable to prevent dust from suddenly accumulating at a certain time series.

[0088] When the dust concentration within the dust distribution area exceeds the standard, the eddy current needs to be adjusted. Considering that the movement and accumulation of dust driven by the eddy current will affect the dust concentration within the dust distribution area. For example, when the pulsed directional eddy current is cleaning the cavity, dust will move from the upper area to the middle area, resulting in the diffusion of dust, or move from the middle area to the bottom area, resulting in the accumulation of dust, thus changing the dust concentration within the dust distribution area. Therefore, it is necessary to implement an eddy current adjustment mechanism to effectively respond to the changes in dust concentration in different dust distribution areas, prevent excessive dust accumulation in a certain area within the cavity, ensure the ability to help clean the accumulated dust, and achieve flexible control of the dust collection system.

[0089] The eddy current adjustment mechanism is as Figure 4 shown and specifically includes:

[0090] Determine the dust distribution area with excessive dust concentration as the dust exceeding standard area, and judge the cavity area where the dust exceeding standard area is located. If there is a dust exceeding standard area in a single cavity area, adjust the eddy current intensity and eddy current direction of the single cavity area 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 standard area, and then it is necessary to judge which cavity area the dust exceeding standard area is in. Because the movement and accumulation of dust in each cavity area are different, and the situations when the dust exceeding standard area is in one cavity area and when it is in two or more cavity areas simultaneously are also different, it is necessary to conduct targeted regulation of the eddy current intensity and eddy current direction to achieve efficient dust collection and removal.

[0092] Specifically, if the dust-exceeding standard area is in a single cavity area, it is necessary to adjust the eddy current intensity and direction within the single cavity area to generate a control signal. For example, when the dust-exceeding standard area is in the upper area, it is necessary to reduce the eddy current intensity because the eddy current speed in the upper area is relatively high, resulting in a strong eddy current impact that causes the dust in the cavity to easily spread and suspend. By appropriately reducing the eddy current intensity, the excessive impact of the eddy current can be reduced, preventing a large amount of dust from migrating towards the bottom area under the drive of the eddy current, thereby stabilizing the dust distribution and preventing the problem of a rapid increase in dust concentration in the bottom area due to excessive dust migration. At the same time, change the eddy current direction so that the eddy current concentrates on the upper area, which is to reduce the tendency of the eddy current to spread from the upper area to the bottom area. In this way, while reducing the overall impact, a certain intensity of eddy current can be maintained in the upper area, enabling the eddy current to not only control the suspension degree of the dust but also continue to entrain and clean the dust with the remaining eddy current force to ensure the cleaning effect of the upper area itself. The control signal generated at this time includes an instruction to reduce the eddy current intensity and adjust the eddy current generator to converge the eddy current towards the upper area.

[0093] When the dust-exceeding standard area is in the middle area, it is necessary to increase the eddy current intensity because the eddy current speed in the middle area is usually medium and relatively stable. In this environment, the dust is concentrated and suspended, making it difficult to be carried out. By increasing the eddy current intensity, the original relatively balanced dust suspension state can be broken, enhancing the fluidity of the dust and prompting the accumulated dust to move with the eddy current for subsequent discharge. At the same time, adjust the eddy current direction to strengthen the guidance of the eddy current towards the upper area or outward diffusion. On the one hand, guide the dust to flow towards the upper area where it is easier to be discharged, and with the relatively strong driving effect of the eddy current in the upper area, accelerate the dust's departure from the middle area. On the other hand, the adjustment of the outward diffusion of the eddy current can prevent the dust from further accumulating in the middle area and avoid excessive dust flowing towards the bottom area causing secondary accumulation. The control signal generated at this time includes an instruction to increase the eddy current intensity and adjust the eddy current generator to prompt the eddy current to spread towards the upper area or outward.

[0094] When the dust - exceeding standard area is in the bottom area, it is necessary to increase the eddy current intensity. This is because the eddy current speed in the bottom area is small and the eddy current intensity is weak, which easily causes dust to accumulate and form sedimentation. Therefore, increasing the eddy current intensity to enhance the eddy current intensity in the bottom area can provide sufficient power for the deposited dust, enabling the dust to overcome gravity and friction, re - suspend and move with the eddy current, preventing further accumulation. At the same time, adjust the eddy current direction to make the eddy current more vertical or flow towards the bottom area. The vertical eddy current is conducive to directly impacting the accumulated dust, loosening and lifting the dust, and the eddy current guided towards the bottom area can prevent the suspended dust from being easily carried out to other cavity areas, reducing interference to other clean cavity areas, and at the same time ensuring that the dust in the bottom area can be fully cleaned under the action of the enhanced eddy current. At this time, the control signal includes 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 area.

[0095] If there are dust - exceeding standard areas in at least two cavity areas, a step - by - step adjustment logic is executed;

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

[0097] If there are dust - exceeding standard areas in multiple cavity areas in the cavity, it will cause cross - influence of dust. For example, pulsed directional eddy currents will carry the dust in one cavity area to another cavity area, resulting in the accumulation of dust in multiple cavity areas, thus exacerbating the concentration exceeding the standard in the dust - exceeding standard areas.

[0098] Here, it is necessary to effectively coordinate and control the eddy current intensity and direction in multiple cavity areas, and guide the dust in the dust - exceeding standard areas to accumulate in a specific area first, and then finally discharge it outside the cavity for cleaning. Then, it is necessary to identify the spatial distribution of dust concentration and step - by - step adjust the eddy current intensity and direction to ensure that the dust is effectively cleaned and collected.

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

[0100] Identify the positions and dust concentrations of the dust - exceeding standard areas, configure the dust - concentrated areas, guide the dust in the dust - exceeding standard areas to the dust - concentrated areas by adjusting the eddy current intensity and direction, then guide the dust in the dust - concentrated areas outside the cavity by adjusting the eddy current intensity and direction, and continuously monitor the dust concentration in the dust - distribution area. If the dust concentration in the dust - distribution area is still exceeding the standard after adjustment, re - execute the eddy current adjustment mechanism to obtain the control signal.

[0101] The position of the dust - exceeding standard area is determined by real - time recognition through a camera, and the dust concentration in the dust - exceeding standard area is identified by a particulate matter concentration sensor. In the dust - exceeding standard area, the goal of the eddy current is to guide the dust from multiple dust - exceeding standard areas to a specific area for centralized accumulation. Here, this specific area is defined as the dust - centralized area. The dust - centralized area can effectively converge the dust from other cavity areas. The dust - centralized area here can be an area close to the cavity outlet (bottle mouth).

[0102] Guide the dust from multiple dust - exceeding standard areas to the dust - centralized area. By increasing the eddy - current intensity, overcome the inertia and viscous resistance of the dust to ensure that the dust can be effectively taken away from the dust - centralized area, so that the dust is discharged from the cavity outlet to the outside of the cavity, avoiding dust retention or dispersion due to insufficient eddy - current intensity. At the same time, according to the position of the dust - centralized area and the positions of each dust - exceeding standard area, uniformly plan the eddy - current direction to ensure that the eddy currents generated in each cavity area directly guide the dust to the dust - centralized area in the unified eddy - current direction, avoiding phenomena such as reverse and cross eddy currents. For example, increase a strong eddy current in the dust - exceeding standard area to drive the dust towards the dust - centralized area.

[0103] When the dust has been successfully concentrated in the dust - centralized area, the goal is to guide the dust to be discharged smoothly outside the cavity through the adjustment of the eddy - current intensity and direction, thus completing the cleaning.

[0104] Specifically, increase the eddy - current intensity between the dust - centralized area and the cavity outlet to accelerate the discharge of the dust outside the cavity through the cavity outlet, ensuring that the dust will not accumulate and block near the cavity outlet. At the same time, adjust the eddy - current direction in the cavity so that the dust converged in the dust - centralized area can flow directly and smoothly towards the cavity outlet, and make the eddy current more vertical or spread towards the cavity outlet, preventing phenomena such as dust backflow and swirling at the outlet, and ensuring the efficient discharge of the dust.

[0105] When guiding the dust outside the cavity, it is necessary to continuously monitor the dust concentration in the dust distribution area, the dust - exceeding standard area, the dust - centralized area, and the cavity outlet, and judge whether it still exceeds the standard. If the dust concentration in the dust distribution area still exceeds the standard after adjusting the eddy - current intensity and direction, it is necessary to re - execute the eddy - current adjustment mechanism to ensure that the dust in the cavity can be cleaned cleanly.

[0106] By judging various situations of dust - concentration exceeding the standard one by one and making distributed adjustments, it is possible to effectively manage the dust distribution in multiple cavity areas and optimize 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 can be compatible with a variety of communication protocols, such as the common CAN bus, etc., so as to quickly and stably receive the control signals generated by the area monitoring module. The received control signals include eddy current intensity adjustment instructions and eddy current direction adjustment instructions, and these instructions are parsed and converted into electrical parameters that can be recognized by the Prandtl pulsed directional eddy current guiding component.

[0109] After the adjustment instruction of the eddy current intensity is parsed, the eddy current generator in the Prandtl pulsed directional eddy current guiding component is gradually fine-tuned. For example, when the dust-exceeding area is in the bottom area, the adjustment instruction of the eddy current intensity is to increase the eddy current intensity. After receiving the instruction, the eddy current generator gradually increases the eddy current flow rate, so that the eddy current flowing into the eddy current generator gradually increases, and then gradually increases the eddy current intensity.

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

[0111] During the whole process of adjusting the eddy current parameters, it is necessary to continuously monitor whether the adjustment of the eddy current intensity and the eddy current direction has achieved the expected effect, that is, whether the dust concentration exceeds the standard in the dust distribution area. 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 generate pulsed directional eddy currents through the Prandtl pulsed directional eddy current guiding component according to the adjusted eddy current parameters, clean the dust in the cavity, and collect and process the guided dust.

[0113] According to the information of the dust distribution area and the dust-exceeding area feedback by the area monitoring module, after adjusting the eddy current parameters through the pneumatic control module, the Prandtl pulsed directional eddy current guiding component is started, so as to generate pulsed directional eddy currents with a certain intensity. The eddy currents first act on the upper area in the cavity. Since the eddy current speed in the upper area is relatively large, the generated impact force is sufficient to blow off or shake off the dust attached to the surface of the upper area in the cavity, making it enter the suspended state.

[0114] As the eddy current continuously flows towards the bottom area, the eddy current speed changes according to the preset gradient at different depths in the cavity, ensuring that sufficient acting forces can be generated at all levels in the cavity area to loosen the dust comprehensively. For example, the eddy current speed in the upper area is relatively large, but as the depth in the cavity increases, the eddy current speed gradually decreases, but always maintains the force capable of keeping the dust suspended and pushing it towards the bottom area.

[0115] When it is found that there is an area with excessive dust in the cavity area, by adjusting the eddy current direction, an oriented eddy current field is formed in the bottle cavity, and more eddy currents act on the area with excessive dust, so that the dust on the surface of the area with excessive dust loosens and moves to the dust concentration area. Then, appropriately increase the eddy current intensity to increase the pushing force on the dust, so that the dust quickly converges towards the cavity outlet (that is, the bottle mouth of the bottle cavity), realizing the cleaning of the dust in the cavity without contacting the inner surface of the bottle cavity and avoiding the damage or secondary pollution that may be caused by physical contact.

[0116] The dust guided by the eddy current will eventually be pushed towards the bottle mouth of the bottle cavity to be guided outside the bottle cavity until the dust is guided into the dust collector. The 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 the bottle cavity.

[0117] The feedback optimization module is used to re-detect whether there is still dust residue in the cavity after cleaning the dust in the cavity. When there is dust residue, optimize the control signal. When there is no dust residue, collect and process the dust.

[0118] The logic for re-detecting whether there is still dust residue in the cavity includes:

[0119] Select sampling points in each cavity area. By monitoring the dust concentration at each sampling point and comparing the dust concentration at each sampling point with the dust concentration threshold, judge whether the dust concentration at each sampling point exceeds the standard, and record the number of sampling points with excessive dust concentration. Configure a number threshold. If the number of sampling points with excessive dust concentration is greater than or equal to the number threshold, there is dust residue in the cavity and it is located in this cavity area, and optimize the control signal;

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

[0121] Select sampling points in each cavity area according to the geometric distribution law of the bottle cavity, and perform detection according to a reasonable monitoring period. For example, re-detect the dust in the bottle cavity every ten minutes. Taking 7 points as an example, the sampling points are preferentially set at angles where dust is likely to accumulate, large changes in slopes, and bottle mouth turning points. For example, in the upper area, select sampling points at the bottle mouth turning point, in the middle area, select 4 sampling points at the connection with the upper area, and select 3 sampling points in the middle section of the bottle cavity. In the bottom area, select 4 sampling points at the connection with the middle area, and select 3 sampling points at the bottle bottom depression of the bottle cavity, making the sampling points more targeted.

[0122] The dust concentration at each sampling point is monitored by 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 dust on light to change the optical signal, and then transmit the returned optical signal back to the receiving end for analysis, so as to judge the dust concentration at each sampling point. Then, compare the dust concentration at each sampling point with the dust concentration threshold to obtain whether the dust concentration at each sampling point exceeds the standard. When the dust concentration at the sampling point is greater than or equal to the dust concentration threshold, it indicates that the dust concentration at this sampling point exceeds the standard.

[0123] Record the monitoring results of each sampling point, count the number of sampling points where the monitored dust concentration exceeds the standard, and synchronously record the cavity area corresponding to the sampling points with excessive dust concentration. Configure a quantity threshold. Specifically, if more than 3 sampling points (including 3 sampling points) out of the 7 sampling points monitored in each cavity area are monitored to have a dust concentration exceeding the standard, it is determined that there is dust residue in the cavity, and further determine that the position of the dust residue is in this cavity area. Then, it is necessary to optimize the control signal, transmit the detailed residue information to the area monitoring module through the CAN bus. The residue information includes the position of the cavity area where the dust residue is located, the distribution of the sampling points with dust residue, and the corresponding values of the dust concentration, etc. Analyze the reasons for the dust residue, such as insufficient eddy current intensity, deviation of the eddy current direction, or unreasonable setting of the initial dust distribution area, etc. According to the analysis results, re-optimize the eddy current adjustment mechanism, including the adjustment of the eddy current intensity and direction, or re-configure the initial dust distribution area, etc., and generate the corresponding control signal, which is sequentially transmitted to the pneumatic control module and the eddy current processing module to drive these two modules to operate according to the new eddy current parameters and clean the dust in the bottle cavity again.

[0124] If only one or two sampling points or no sampling points are monitored to have a dust concentration exceeding the standard among the 7 sampling points monitored in each cavity area, it is determined that there is no dust residue in the cavity, and no adjustment is required for the time being. Continue to monitor the next monitoring cycle, and regularly clean the dust collector to ensure the dust collection efficiency and obtain timely and effective treatment.

[0125] Embodiment 2

[0126] As Figure 1 shown, the device structure diagram of the Prandtl pulsed directional eddy current integrated dust collector provided by the embodiment of the present application is as follows. The device includes:

[0127] The Prandtl pulsed directional eddy current guiding component is used to form a pulsed directional eddy current in the cavity 4 to clean the dust in the cavity 4.

[0128] The Prandtl pulsed directional eddy current guiding 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 pulsed directional eddy currents and receive control signals generated by the dust collection system to adjust the eddy current parameters of the pulsed directional eddy currents. The fixed cover 3 is a detachable structure for closing the main body 1.

[0129] The function of the Prandtl pulsed directional eddy current guiding component is to generate tornado-like pulsed directional eddy currents through the eddy current generator 2 to clean the dust in the cavity 4. The cavity 4 is a bottle-shaped cavity, and the fixed cover 3 can be easily detached to replace different cavities 4 for cleaning, which can effectively solve the problems of dust and foreign matter accumulation and inability to remove caused by structural dead corners in the cavity 4, and can efficiently remove the adsorbed dust inside and outside the cavity 4.

[0130] The cavity 4 needs to be placed around the eddy current generator 2, and the eddy current generator 2 passes through the bottle mouth of the cavity 4 and is located inside the cavity 4 so that the pulsed directional eddy currents generated by the eddy current generator 2 can effectively act on the dust in the cavity 4. To improve the cleaning effect of the cavity 4, the pulsed directional eddy currents generated by the eddy current generator 2 should be able to generate sufficient force 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 displace or vibrate during operation, thus affecting the generation and propagation of the pulsed directional eddy currents. The main body 1 can provide a stable platform to keep the eddy current generator 2 always in its best working state; moreover, the eddy current generator 2 can receive control signals generated by the dust collection system to adjust the eddy current parameters of the pulsed directional eddy currents. The eddy current parameters include eddy current intensity and eddy current direction, so as to clean the dust in the cavity 4 cleanly and avoid the accumulation of dust into a dust distribution area under the action of the pulsed directional eddy currents.

[0132] The fixed cover 3 is a detachable structure for closing the main body 1 to ensure the airtightness during the cleaning process of the cavity 4 and avoid the leakage of the pulsed directional eddy currents of the eddy current generator 2 or the interference of the external environment on the cleaning process. Usually, when the fixed cover 3 closes the main body 1, it can also fix the cavity 4 at the same time to prevent the cavity 4 from loosening under the action of the pulsed directional eddy currents. The design of the detachable structure is convenient for replacing different cavities 4 for cleaning the dust in different cavities 4, improving the flexibility and application range of the Prandtl pulsed directional eddy current guiding component, and enabling targeted cleaning of different cavities 4.

[0133] The main body 1 is the basis of the Prandtl pulse directional eddy current guiding component, providing stable support. When the eddy current generator 2 is 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 stably placed 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.
