Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressure relief dustproof material guide groove, more particularly to a pressure relief dustproof material guide groove device for conveyor. BACKGROUND

[0002] As the core equipment for bulk material transportation, the material guide groove device of the belt conveyor bears the dual functions of material guiding and dust control. The existing pressure relief dustproof material guide groove is usually composed of a sealed tank, an inclined pressure relief baffle and a circulating air duct. Its working principle is to guide the airflow carrying dust into the lateral circulating channel by buffering the impact force of the falling material through the baffle, and finally discharging it after being filtered by the dust removal system. The pressure relief and dust removal rely on the airflow distribution characteristics under the free-fall state of the material, and the dust is recycled by using the negative pressure air duct.

[0003] However, when the poured material impacts the pressure relief baffle in the form of free fall, the fine dust carried inside is difficult to be effectively captured by the airflow due to insufficient diffusion, forming a dust core accumulation phenomenon. The single inlet structure of the circulating air duct leads to an unbalanced distribution of the tangential component of the airflow in the material guide groove cavity, forming a high-pressure vortex in the local area, which not only reduces the dust removal efficiency, but also causes secondary dust dispersion.

[0004] The root cause of the problems of most existing pressure relief dustproof material guide grooves lies in the fact that the traditional pressure relief end structure cannot coordinate the dynamic coupling relationship between material diffusion and airflow organization. The concentrated impact flow formed by the free-fall material compresses the effective pressure relief space of the cavity, and the single inlet cyclone separation type air duct produces a low pressure dead zone in the center area due to the forced vortex core effect, further hindering the migration of dust. Limited by the rigid baffle layout and one-way air duct design, it is neither possible to actively disperse the material for a second time to release the dust source, nor to build a uniform tangential flow field to eliminate the vortex core.

It should be noted that the following embodiments are the best and preferred embodiments, and other alternative embodiments can also be used by those skilled in the art; and the drawings are only used to more specifically describe the embodiments, and are not intended to limit the present application.

[0050] As shown in the drawings, Figures 1 to 9 The pressure relief dustproof material guiding groove device for conveyors provided by the present application includes a pressure relief cylinder 1, which is a horizontally arranged cylindrical structure. A material guiding cover opening 2 is installed at the middle of the top of the pressure relief cylinder 1. A material discharging cover opening 3 is installed at the middle of the bottom of the pressure relief cylinder 1. A bidirectional electric control servo telescopic rod 4 is fixedly installed at the middle of the outer surface of the pressure relief cylinder 1. The telescopic ends of the bidirectional electric control servo telescopic rod 4 on both sides are flush with the horizontally arranged direction of the pressure relief cylinder 1. A first vortex generating unit 6 is arranged on one side of the telescopic end, and a second vortex generating unit 7 is arranged on the other side of the telescopic end.

[0051] The pressure relief cylinder 1 is provided with an umbrella-shaped outwardly spreading buffer layer mechanism 9 at the center of the bottom, which is opposite to the material guiding cover opening 2. The umbrella-shaped outwardly spreading buffer layer mechanism 9 can spread the introduced material again to release the dust source.

[0052] The first vortex generating unit 6 and the second vortex generating unit 7 are both provided with independent air ducts. The independent air ducts of the first vortex generating unit 6 and the second vortex generating unit 7 are inserted into the inner bottom of the pressure relief cylinder 1 near the material discharging cover opening 3 through a push mechanism 8 arranged near the position of the end surface of the pressure relief cylinder 1. The push mechanism 8 can form a low-pressure sedimentation area at the center of the bottom of the pressure relief cylinder 1 through the counter-rotating vortex, so as to assist the material and the dust source to be forced to gather downward.

[0053] To solve the problem of low pressure dead zone caused by forced vortex effect of single inlet air duct of existing pressure relief dustproof material guide chute, which leads to dynamic coupling disorder of dust diffusion and airflow organization, causing dust core accumulation and secondary dispersion, the above technical scheme is used to solve the problem. The above technical scheme mainly comprises a pressure relief cylinder 1, a material guide cover 2, a material discharge cover 3, a bidirectional electric control servo telescopic rod 4, a first vortex generating unit 6, a second vortex generating unit 7, a double push mechanism 8 and an umbrella-shaped outward scattering buffer layer mechanism 9. The pressure relief cylinder 1, the material guide cover 2 and the material discharge cover 3 are integrated, the pressure relief cylinder 1 as the main pressure relief area is a horizontally arranged cylindrical structure, and the two sides are open to facilitate the subsequent connection of the double push mechanism 8 on both sides. The material guide cover 2 and the material discharge cover 3 are connected one above the other at the middle position. The material to be transported is poured into the material guide cover 2, and after active pressure relief and dust removal in the pressure relief cylinder 1, it is discharged from the material discharge cover 3. The discharged material passes through the existing guide inclined plate and falls on the conveyor in the conveying state. The bidirectional electric control servo telescopic rod 4 is arranged at the middle position of the outer arc surface of the pressure relief cylinder 1. It is an electric control telescopic rod structure that can simultaneously servo stretch on both sides in the existing technology, and has independent control units on both sides, that is, it can ensure the synchronization of the stretching output ends on both sides, or it can stretch one end alone, and can be selectively servo adjusted according to the needs. The first vortex generating unit 6 and the second vortex generating unit 7 have the same overall structure, and are arranged on both sides of the pressure relief cylinder 1 through the output ends of the bidirectional electric control servo telescopic rod 4. In the first vortex generating unit 6 and the second vortex generating unit 7, independent air duct generating ends are arranged to generate high pressure air ducts, which are poured into the inside from both sides of the pressure relief cylinder 1. At the intersection of the high pressure air duct pouring areas on both sides, the umbrella-shaped outward scattering buffer layer mechanism 9 is arranged, and the umbrella surface faces the material guide cover 2, so that the material poured into the material guide cover 2 is scattered again by the unfolded umbrella surface to release dust sources. Since the intersection is in the high pressure air duct pouring area on both sides, the released dust sources can be better handled. Only by making the first vortex generating unit 6 and the second vortex generating unit 7 enter opposite high pressure air ducts, a low pressure settlement area is formed at the bottom center intersection of the pressure relief cylinder 1, which can assist the material and the scattered dust sources to be forced to gather downward, solve the problem of low pressure dead zone caused by forced vortex effect of single inlet air duct of existing pressure relief dustproof material guide chute, which leads to dynamic coupling disorder of dust diffusion and airflow organization, causing dust core accumulation and secondary dispersion.

[0063] Among them, the umbrella-shaped outer dispersion buffer layer mechanism 9 is essentially an outwardly expanding umbrella-shaped elastic structure, the umbrella-shaped outer cover 93 constituting the outer umbrella surface is a high wear-resistant and ductile soft rubber structure, and is sleeved on the outer side of the vice support sleeve 97 through a plurality of reset telescopic rods 95, the reset telescopic rods 95 are spring sleeve rod structures capable of resetting in the prior art, and the settlement monitoring assembly is arranged in the sleeve rod for resetting, in the process of each time the umbrella-shaped outer cover 93 of the outer umbrella surface being tilted by the material, the settlement monitoring assembly on the spring sleeve rod can record the data of the downward pressure in real time, that is, the degree of downward pressure of the spring sleeve rod, and the recorded downward pressure data is transmitted and stored into the pressure sensor 98 through the one-to-one corresponding convex sensing probe 99, so that the pressure sensor 98 in the vice support sleeve 97 can master the material accumulation condition of the umbrella-shaped outer cover 93 of the outer umbrella surface in real time. The circular ring sleeve 96 is used to hinge each side reset telescopic rod 95.

[0064] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the complex pushing mechanism 8 further comprises a bearing sleeve 87 fixedly installed on the outer surface of the externally expanded screw port 86, and the outer surface of the bearing sleeve 87 is provided with a sawtooth electrode wind guide module 10, which comprises a gallium-indium alloy cavity ring 101, a plurality of cavity fan blades 102 are fixedly installed on the outer ring surface of the gallium-indium alloy cavity ring 101 at equal intervals, a wire 103 is arranged in the inner cavity of the gallium-indium alloy cavity ring 101, the wire 103 penetrates into the inner cavity of each cavity fan blade 102, and a composite sawtooth electrode strip 104 connected in series with the wire 103 is fixedly installed on the outer edge of each cavity fan blade 102.

[0065] The bearing sleeve 87 is arranged to provide a movable rotating shaft on the outer surface of the externally expanded screw port 86, so that the sawtooth electrode wind guide module 10 connected to the outer side of the bearing sleeve 87 can smoothly and flexibly rotate under the influence of the air duct. The sawtooth electrode wind guide module 10 comprises a gallium-indium alloy cavity ring 101 made of gallium-indium alloy material to better guide static electricity, and the inside is a cavity structure for connecting the wire 103 in series, and the composite sawtooth electrode strip 104 on the cavity fan blade 102 on the outer side of the gallium-indium alloy cavity ring 101 is connected in series through the wire 103. The wire 103 is connected to an external high-voltage power supply, the sawtooth tip of the composite sawtooth electrode strip 104 gathers high-density electric charge, and a non-uniform strong electric field is formed. The outer edge of the rotating cavity fan blade 102 has a static induction effect, and the composite sawtooth electrode strip 104 generates a sharp static electric field when electrified, so that the dust particles passing through are charged. The aerosol dust particles flowing through the cavity fan blade 102 are ionized under the action of the strong electric field, and the charged dust particles are attached to the surface of the scraping brush 105, and are physically transferred to the inlet layer of the gradient adsorption cotton block 811 under the action of the electric field force.

[0066] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the complex pushing mechanism 8 further comprises a storage cavity 89 opened in the inner side of the side-through type adsorption cover 88, and an inclined return guide pipe 810 connected to the inside of the discharge cover port 3 is fixedly installed on the bottom of the storage cavity 89. The storage cavity 89 stores a gradient adsorption cotton block 811, and the cavity fan blade 102 is fixedly installed with a scraping brush 105 on one side of the conical disc cover 82 and the gradient adsorption cotton block 811.

[0067] The configured storage cavity 89 is a circular cavity, which is located at the side of the sawtooth electrode wind guide module 10, and is used to store the gradient adsorption block 811. Since the side-through type adsorption cover 88 is rotatably installed, it can be quickly disassembled and assembled, and the gradient adsorption block 811 can be conveniently replaced and maintained. On the outer edge of the cavity fan blade 102, a scraping brush 105 is arranged. The scraping brush 105 is a high-toughness brush structure. Since the composite sawtooth electrode strip 104 is installed on the outer edge of the cavity fan blade 102, the scraping brush 105 is arranged on both sides of the composite sawtooth electrode strip 104, that is, the composite sawtooth electrode strip 104 is clamped therebetween. After the composite sawtooth electrode strip 104 is powered on, the sawtooth tip generates a strong electric field to make the dust particles passing through carry electric charges. The rotating cavity fan blade 102 forms a double effect through the two side scraping brushes 105. The scraping brush 105 on the side of the conical disc cover 82 removes the attached dust particles and introduces the airflow. The scraping brush 105 on the side of the gradient adsorption block 811 sweeps the charged dust particles to the surface of the inlet layer. When the inlet layer of the gradient adsorption block 811 accumulates dust particles to a critical mass, the friction between the bottom of the gradient adsorption block 811 and the slope of the storage cavity 89 is reduced, and the gradient adsorption block 811 slides along the inclined bottom surface into the inclined return material guide pipe 810. The inclination angle of the inclined return material guide pipe 810 is greater than the material rest angle, so as to ensure that the saturated gradient adsorption block 811 slides into the discharge cover opening 3 inside by gravity, and is discharged from the system with the main material flow. During the whole process, the scraping brush 105 continuously scrapes the surface of the conical disc cover 82 when the cavity fan blade 102 rotates, so as to remove the accumulated dust and avoid electric field shielding. The removed dust also slides into the discharge cover opening 3 inside through the inclined return material guide pipe 810.

[0068] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown in the drawings, the gradient adsorption block 811 is a multilayer block structure. One side of the gradient adsorption block 811 close to the cavity fan blade 102 is an inlet layer. One side of the gradient adsorption block 811 close to the side of the side-through type adsorption cover 88 is an outlet layer. A core layer is arranged between the inlet layer and the outlet layer of the gradient adsorption block 811. The inlet layer is a polyurethane sponge. The outlet layer is a fiber membrane. The core layer is an activated carbon fiber block.

[0069] The gradient adsorption wad 811 is essentially a multi-layer wad structure in the prior art, wherein the side close to the cavity fan blade 102 is an inlet layer, the inlet layer is a hydrophilic polyurethane sponge, is composed of a hydrophilic polyurethane sponge, and serves as a primary interception end. The dust particles are swept to the inlet layer by the scraping brush 105, the hydrophilic polyurethane sponge captures the dust group through capillary effect, that is, neutralizes the electric charge in the inlet layer to prevent dust aggregation. The side close to the side of the side-through adsorption cover 88 is an outlet layer, the outlet layer is a fiber membrane, and is used to cooperate with the activated carbon fiber wad of the core layer to adsorb the humid gas in the material, thereby further improving the interception capacity of the wad filtration end.

[0070] The use method provided by the application is specifically as follows:

[0071] First, the material to be transferred and conveyed is poured into the guide cover opening 2, the poured material enters the inside of the pressure relief cylinder 1, and is secondarily dispersed by the umbrella-shaped outer dispersion buffer mechanism 9 arranged in the pressure relief cylinder 1. Specifically, the material impacts the inclined umbrella surface of the umbrella-shaped outer cover 93 in the form of free fall, the umbrella surface of the high-wear-resistant soft rubber material produces radial elastic expansion, the large-particle material is bounced to the periphery due to the curvature of the umbrella surface, and the micro-fine dust group is overflowed outward under the action of the impact force, so that the poured material is fully dispersed. The impact force of the material is transmitted to the reset telescopic rod 95 hinged to the umbrella surface, triggering the staged compression of the spring sleeve rod inside the reset telescopic rod 95, because a plurality of reset telescopic rods 95 are arranged at different positions of the umbrella surface in the umbrella-shaped outer cover 93, the compression of the outer umbrella surface when the material is guided can be effectively recorded while the material is dispersed to the periphery. If it is a transient strong impact, the spring sleeve rod rapidly contracts, records the peak kinetic energy absorbed, and indicates that there is more material at the moment. In most cases, the material is continuously poured, the spring maintains a partially compressed state, and an inclined platform is formed on the umbrella surface.

[0072] Then, during the process of secondarily dispersing the poured material by the umbrella-shaped outer cover 93, the reset telescopic rod 95 maintains a partially compressed state when the material is continuously poured, and the pressure sensing array of the central position of the linkage sensor 94 can monitor the deformation difference of the umbrella surface in real time. If the left quadrant deformation variable is continuously greater than the right quadrant, the system can be marked as a material unbalanced impact area at this time. When the material unbalanced impact area appears, the linkage control system triggers the power of the right high-pressure fan 65 to be increased, the intensity of the opposite vortex is enhanced, the dust source path is forced to be pulled back to the center, and in summary, the pressure distribution of the umbrella surface is restored to balance to change the power of the two high-pressure fans 65, so that the dust source is smoothly pressed into the inside of the pressure relief cover opening 3.

[0073] In the process of pouring the material into the umbrella-shaped cover 93, when the amount of material is large, the linkage control system can trigger the high-pressure fan 65 in the first vortex generating unit 6 and the second vortex generating unit 7 on both sides to rotate reversely, so that the suction air ducts are generated in the air guide straight pipes 61 on both sides, which are different from the output air ducts that press downward to the side of the discharge cover 3. The reverse suction air ducts on both sides can temporarily expand the flow area of the dust source path, that is, directly increase the recovery path of the dust source, and change the discharge path of the discharge cover 3 to the larger suction path on both sides. In the suction process, the first vortex generating unit 6 and the second vortex generating unit 7 on both sides will suck the dust source generated instantaneously into the storage cavity 89 of the side-through type suction cover 88. Through the rotation of the cavity fan blade 102 in the rotating state of the sawtooth electrode air guide module 10, the scraping brush 105 on the side of the composite sawtooth electrode strip 104 is thrown to the surface of the gradient suction cotton block 811, and the debris on the conical disc cover 82 is swept into the bottom of the storage cavity 89. Finally, the slanting return guide pipe 810 is guided into the discharge cover 3. The reverse suction air duct, on the one hand, causes the suction air duct to be generated in the inside of the disc sealing cover 62 through the communication air port 63 outside the air guide straight pipe 61. At this time, the gradient suction cotton block 811 in the storage cavity 89 in the communication state has suction force due to the loose cotton block material, which further assists in enhancing the suction capacity of the gradient suction cotton block 811 on both sides. On the other hand, the reverse suction air duct re-presses the reverse suction from the first telescopic pipe 64 into the material guide cover 2, forming a downward air duct on the inner wall of the material guide cover 2 to press down the dust particles of the instantaneously scattered material, and completing the secondary dust suppression work.

[0074] Finally, when the umbrella surface pressure distribution is continuously unchanged, the corresponding time threshold value can be set according to the type of the material to be conveyed. For example, when the umbrella surface pressure distribution is continuously unchanged for 5 minutes, the telescopic ends of the bidirectional electric control servo telescopic rod 4 on both sides are retracted, and the U-shaped pull pipe 5 on both sides is moved close to the pressure relief cylinder 1. In this process, the first telescopic pipe 64 and the second telescopic pipe 81 are synchronously retracted, the arc-shaped scraper 85 outside the servo motor 83 is moved from both sides to the side of the discharge cover 3, the material scattered by the umbrella-shaped outer scattering buffer layer mechanism 9 on both sides of the pressure relief cylinder 1 is pushed into the inside of the discharge cover 3, the scraper cleaning trigger work is completed, and in this process, the servo drive at the output end of the servo motor 83 can control the rotation of the arc-shaped scraper 85 to completely clean the material accumulated on both sides of the pressure relief cylinder 1.

[0075] For example, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the umbrella-shaped outer buffer layer mechanism 9 further comprises a linkage sensor 94 fixedly installed at the center of the outer surface of the umbrella-shaped outer cover 93, which is configured with a pressure sensing array for collecting pressure distribution data of the umbrella surface circumference of the umbrella-shaped outer cover 93;

[0076] The linkage sensor 94 is connected to a linkage control system, which comprises:

[0077] A signal acquisition module is configured to acquire pressure intensity and azimuth data of each region of the umbrella surface through the pressure sensing array, and to acquire vertical pressure gradient data of the low-pressure settlement area through the settlement monitoring component integrated in the auxiliary support sleeve 97, thereby generating multi-source signals that fuse the impact state and settlement efficiency of the umbrella surface;

[0078] An intelligent analysis module is configured to receive the multi-source signals, analyze the correlation between the umbrella surface pressure distribution and the vertical pressure gradient through logic analysis, and output a state determination result containing material load imbalance azimuth identification and eddy current intensity level;

[0079] An execution control module is configured to execute response operations according to the state determination result:

[0080] In response to the material load imbalance azimuth identification, an eddy current balance instruction is generated by adjusting the power of the high-pressure fan 65 of the corresponding side eddy current generation unit;

[0081] In response to the insufficient eddy current intensity level, an eddy current strengthening instruction is generated by cooperatively increasing the power of the high-pressure fans 65 on both sides and controlling the bidirectional electric servo telescopic rod 4 to drive the inclined convex pipe 84 to displace to a preset focusing position;

[0082] When the umbrella surface pressure distribution remains in a static threshold, a self-cleaning action is performed by starting the servo motor 83 to drive the arc-shaped scraper 85;

[0083] A closed-loop verification module is configured to dynamically calibrate the power parameters of the high-pressure fan 65 based on the dust concentration feedback data at the outlet of the discharge cover 3 and return the parameters to the execution control module.

[0084] The pressure sensing array is integrated in the linkage sensor 94 at the center of the outer surface of the umbrella-shaped outer cover 93, and is a distributed sensor network composed of multiple pressure sensing units. These units are connected to the pressure sensors 98 in the array-form distributed reset telescopic rod 95, forming a detection array distributed on the umbrella surface, which divides different regions of the umbrella surface circumference into left and right quadrants to correspond to the first and second eddy current generation units 6, 7 on both sides.

[0085] The pressure intensity and azimuth data of each area of the umbrella surface are acquired by the pressure sensing array, and the vertical pressure gradient data of the low-pressure settlement area are acquired by the settlement monitoring assembly integrated in the auxiliary support sleeve 97, to generate multi-source signals that fuse the impact state of the umbrella surface and the settlement efficiency. That is, when the material falls from the guide cover opening 2 and impacts the umbrella cover 93, the impact force of the material on different areas of the umbrella surface acts on the outer convex sensing probe 99 of the reset telescopic rod 95 below it. Based on the pressure detection of the outer convex sensing probe 99, each outer convex sensing probe 99 independently detects the pressure intensity of the local area of the umbrella surface where it is located, i.e. the force per unit area is transmitted to the pressure sensor 98, to complete the acquisition work of the signal acquisition module of the linkage sensor 94, facilitating the linkage sensor 94 to read the signals of all sensing units. In the correlation process, since the physical position of the sensing unit on the umbrella surface is fixed and known, i.e. each articulated reset telescopic rod 95 is fixed, the signal acquisition module can accurately correlate the pressure intensity value and the azimuth information detected by each sensing unit. The system integrates the data of all sensing units to generate a data set reflecting the spatial distribution of pressure intensity on the entire umbrella surface in real time, so that the system knows which area has high pressure and which area has low pressure, as well as the relative size of the pressure. The area with high pressure indicates that it is a material concentrated impact area, while the area with low pressure indicates that it is a weak impact area or an impact-free area.

[0086] The data sources of the multi-source signals are essentially umbrella impact data and settlement area data. The umbrella impact data is provided by the pressure sensing array of the linkage sensor 94, including the pressure intensity and azimuth of each area of the umbrella surface. The settlement area data is provided by the settlement monitoring assembly integrated in the auxiliary support sleeve 97. The assembly is integrated in the reset telescopic rod 95 and belongs to the displacement sensor monitoring device in the prior art. It monitors the settlement by the spring compression amount set inside, which monitors the pressure change gradient in the vertical direction of the low-pressure settlement area at the center of the umbrella cover 93 directly below, i.e. the intersection of the bottom center of the pressure relief cylinder 1, which is formed by the vortex. To reflect the strength of the effect of the vortex on the downward forced gathering of the material and dust source.

[0087] The intelligent analysis module is essentially a device for generating a state determination result, and its workflow can be summarized as receiving multi-source signals, logical correlation analysis, and outputting a state determination result. Specifically, the intelligent analysis module receives the fusion signal sent by the signal acquisition module, which contains both the data set of the pressure distribution on the umbrella surface and the vertical pressure gradient data of the low-pressure settling zone. Then, according to the data, it performs logical correlation analysis to determine whether the pressure distribution on the umbrella surface is uniform. If the data set of the pressure distribution shows that the pressure in one quadrant is significantly higher than that in another quadrant, and the vertical pressure gradient of the settling zone does not change much or even decreases, it indicates that there is a material load imbalance impact, i.e., the material is not evenly dispersed, and the current vortex intensity is not enough to effectively pull the dust source in the imbalance area to the center for settling. By analyzing the difference between the vertical pressure gradient and the expected target, if the vertical pressure gradient is lower than the preset effective settling threshold, even if the pressure distribution on the umbrella surface is relatively uniform, it indicates that the overall vortex intensity is insufficient to form a strong low-pressure area to effectively collect dust downward. In actual work, since the materials transported by the conveyor are different, the pressure feedback is different, so the settling threshold needs to be adjusted according to the transportation state of different materials to further adapt to the actual situation. Then, according to the situation, the state determination result is output. Based on the above analysis, the module outputs the result containing the key state identifier, i.e., the material load imbalance orientation identifier and the vortex intensity level, which clearly indicates to the first vortex generation unit 6 and the second vortex generation unit 7 on both sides which side of the umbrella surface area has a material concentration impact, in order to increase the strength of the corresponding side air duct. After receiving the material load imbalance orientation identifier, the execution control module will specifically increase the power of the high-pressure fan 65 of the vortex generation unit on the opposite side of the imbalance area. The increase in power means that the tangential wind speed and wind volume on that side are enhanced, and the stronger relative vortex will generate a stronger asymmetric tangential flow field in the pressure relief cylinder 1, forming a fluid dynamic effect that strongly pulls the material and dust in the imbalance area to the central low-pressure settling zone, thereby balancing the impact and promoting the material and dust to be more evenly aggregated and settled to the center. The command only adjusts the power on the opposite side of the imbalance, aiming to restore the symmetry and balance of the vortex field.

[0088] For the response to the vortex intensity level, the so-called vortex intensity level is insufficient, that is, if the vertical pressure gradient is lower than the preset effective settlement threshold, it indicates that the overall vortex intensity is insufficient, and it is not possible to form a low pressure area with sufficient strength to effectively gather dust sources downward. At this time, after the control module receives the vortex intensity level determination, it will simultaneously increase the power of the high-pressure fan 65 of the first vortex generating unit 6 and the second vortex generating unit 7 on both sides, and control the two-way electric control servo telescopic rod 4 to drive the inclined convex pipe 84 on both sides to move to the preset focusing position. In terms of the working principle of the structure, it is to increase the power of the high-pressure fan 65 on both sides at the same time, increase the overall tangential wind speed and wind volume injected from both sides of the pressure relief cylinder 1, directly enhance the vortex intensity, control the two-way electric control servo telescopic rod 4 to actuate contraction or extension, and drive the complex push mechanism 8 and the inclined convex pipe 84 to move along the pressure relief cylinder 1 axis through the U-shaped pull pipe 5. This preset focusing position is determined through learning, which can make the outlet of the inclined convex pipe 84 closest to the position above the center of the low-pressure settlement area. Then move the inclined convex pipe 84 to make its outlet closer to the core of the settlement area, which can more directly and more concentratedly guide the high-speed airflow to the settlement area, strengthen the low-pressure effect of the vortex core, and significantly improve the ability to forcibly gather dust and fine materials downward.

[0089] Response to the umbrella surface static threshold, that is, the umbrella surface static exceeds the set time, and the set time also needs to be adjusted according to the conveying situation of different materials. When the signal continuously shows that the umbrella surface pressure distribution is in a very low static threshold, it means that there is no material impact for a long time, and the execution control module will start the servo motor 83 to drive the arc-shaped scraper 85 to rotate. Combined with structural analysis, it is that no material passes for a long time, and the inner wall of the pressure relief cylinder 1 and the surface of the umbrella-shaped cover 93 may accumulate static dust. After starting the servo motor 83, its output shaft drives the inclined convex pipe 84 and the arc-shaped scraper 85 fixed at the root thereof to rotate. The outer edge of the rotating arc-shaped scraper 85 closely fits the inner wall of the pressure relief cylinder 1, like a scraper, which scrapes off the accumulated dust attached to the inner wall. The scraped dust is finally discharged through the bottom discharge cover opening 3 under the action of gravity and subsequent airflow, so as to keep the cylinder clean and prevent the accumulated dust from affecting the subsequent pressure relief and dust removal effect and equipment operation.

[0090] The specific operation and working principle of the closed-loop verification module are as follows:

[0091] First, a dust concentration sensor, such as an optical scattering sensor, is installed at the outlet of the discharge cover opening 3 or immediately above the conveying belt. The sensor monitors the dust concentration in the discharged material flow or escaping airflow in real time.

[0092] Then the closed-loop verification module continuously receives feedback data from the dust concentration sensor, and compares the actual detected dust concentration with the set target value or the expected dust removal efficiency. If the concentration is higher than the target value, i.e. the dust removal is insufficient, the module generates an instruction to slightly and gradually increase the power parameter of the high-pressure fan 65, which may be on the unbalanced load side, the opposite side, or both sides based on the type of control instruction currently being executed. After the power is increased, the module continues to monitor the concentration change.

[0093] Then, if the concentration decreases below the target value, the current power is maintained; if it is still higher than the target, the power is continued to be gradually increased until the upper limit of the fan is reached or the concentration meets the standard. If the concentration is too low and there is room for power reduction, a slight power reduction is attempted to save energy. The calibration process is based on real-time feedback of dust concentration, and the goal is to use the lowest possible power to meet the dust removal requirements, thereby optimizing energy consumption.

[0094] Finally, the optimal power parameter determined after calibration is fed back to the execution control module, which updates the power setting value in the control instruction accordingly, so that the more optimal parameter verified by practice is used in subsequent execution of the same type of instruction, such as vortex balance and vortex strengthening.

[0095] In summary, the linkage sensor 94 collects the pressure distribution on the umbrella surface, the settlement monitoring assembly in the secondary support sleeve 97 collects the vertical pressure gradient in the settlement area and fuses it into multi-source signals, and then analyzes the correlation to output the state judgment. If the load is unbalanced, the power of the fan on the opposite side of the unbalanced load is adjusted, i.e. vortex balance; if the vortex is weak, the power of the fans on both sides is increased and the inclined pipe is moved to focus, i.e. vortex strengthening; if the umbrella surface is stationary, the wiper is started to clean. Closed-loop detection is to monitor the dust concentration at the discharge port to dynamically adjust the fan power and feed back the optimal parameter to the execution control.
