Description

Technical Field

[0001] This invention relates to the field of flexible dust removal device technology, and in particular to a flexible dust removal device based on differential pressure and filter load feedback. Background Technology

[0002] In the field of industrial dust removal and air purification, bag filters are widely used due to their high filtration efficiency. However, existing dust removal technologies generally suffer from the following problems: First, traditional dust removal methods are mostly rigid controls based on time or pressure, making it difficult to adaptively adjust according to the actual dust load of the filter media. This results in high energy consumption during dust removal and the filter bags are easily damaged by excessive blowing. Second, the actions of the dust removal actuators are relatively simple, mostly involving instantaneous high-pressure airflow impact or rigid vibration. The dust removal process is violent, which not only causes significant mechanical stress on the filter media itself, affecting the lifespan of the filter bags, but also makes it difficult to accurately unclog the filter pores, resulting in incomplete dust removal. Third, existing devices lack real-time feedback and collaborative processing mechanisms for the filter media status during the filtration process. When local blockage occurs in the filter pores, timely and targeted treatment cannot be carried out, which can easily cause a sharp increase in local resistance, affecting the overall filtration efficiency and even causing the equipment to shut down due to excessive pressure. Therefore, we propose a flexible dust removal device based on differential pressure and filter load feedback. Summary of the Invention

[0003] In order to overcome the technical problems existing in the prior art, the present invention provides a flexible dust removal device based on differential pressure and filter load feedback.

[0005] Furthermore, an air tank is installed through the side of the cabinet, and air jet pipes are equidistantly arranged between the air intake component and the filter component. Connecting pipes are fixedly connected to the side of the air tank at equal intervals and extend into the air jet pipes.

[0006] Furthermore, the fixing plate is fixedly installed on the inner side of the cabinet, the mounting bracket is fixedly installed on the upper side of the fixing plate, the fan impeller is located on the inner side of the mounting bracket, and the motor is fixedly connected to the side of the fan impeller.

[0007] Furthermore, a connecting frame is fixedly installed on the lower side of the fan impeller, and the filter plate and the connecting frame are fixedly installed on the side of the connecting frame. The filter plate is an arc-shaped plate made of activated carbon, and the filter plate and the blocking plate are attached to the inner side of the mounting frame.

[0008] Furthermore, the movable plate is slidably installed on the inner side of the cabinet, and a slot is provided on the side of the movable plate. The guide tube is threadedly installed on the inner side of the slot, and the mating frame is threadedly installed on the inner side of the guide tube. The mating frame has a mating groove on its side, and the support tube is fixedly connected to the lower side of the mating frame. The filter tube is located on the lower side of the support tube.

[0009] Furthermore, the mounting plate has mounting grooves equidistantly provided on its side, and constraint rings are symmetrically fixedly connected between the two sides of the mounting plate and the inner side of the mating frame. The mounting strip and the constraint strip are movably installed inside the mounting groove and are engaged with each other. The insertion block is inserted into the filter hole.

[0010] Furthermore, the movable block is movably installed inside the guide channel, the support spring is fixedly connected between the side of the movable block and the wall of the guide channel, the guide rod is fixedly installed on the side of the movable block and passes through the guide cylinder to fit against the side of the filter cylinder, and a filter ring is fixedly installed on the lower side of the guide cylinder.

[0011] Furthermore, the rotating block is rotatably mounted on the inner side of the vibration ring, and the elastic strip is fixedly connected between the outer side of the vibration ring and the inner side of the mounting plate.

[0012] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention combines a filter assembly, a suction assembly, and an air tank for blowing, forming a multi-layered flexible cleaning device that integrates adaptive mechanical cleaning, pneumatic back-blowing cleaning, and high-frequency vibration cleaning. This device uses the airflow pressure change generated by the filter load itself as a feedback signal to drive the filter cartridge to slide inside the guide tube, thereby driving the insertion block to mechanically unblock the filter holes and achieve adaptive adjustment for cleaning as needed. At the same time, the airflow channel is switched by the cooperation of the blocking plate and the exhaust groove, triggering the filter ring back-blowing and the air tank for active blowing. Combined with the resonance effect generated by the swirl block driven by the airflow, it achieves efficient and gentle cleaning of the clogged filter holes.

[0013] 2. This invention cleverly utilizes the pressure difference caused by filter pore blockage as a driving force through the sliding design of the filter cartridge within the guide tube. When dust accumulation in the filter pores causes the resistance to rise, the airflow automatically pushes the filter cartridge upward, causing the insertion block to gradually exit from the filter pores. The scraping action during the exit process achieves precise unblocking. This mechanical dust removal method based on load feedback can achieve automatic matching of dust removal force and degree of blockage without the need for external sensors and complex control systems. The dust removal process is gentle and energy-saving, effectively avoiding the damage to the filter bag caused by traditional rigid dust removal.

[0014] 3. The device of this invention integrates three modes: passive mechanical cleaning, active back-blowing cleaning with air tank, and high-frequency vibration cleaning. When the filter holes are slightly clogged, the resonance generated by the airflow driving the rotating block drives the insertion block to vibrate at high frequency in the filter holes, realizing routine maintenance cleaning. When the filter holes are severely clogged, the air tank triggers high-pressure jet to blow the filter holes in reverse. At the same time, the high-pressure airflow drives the rotating block to rotate at high speed to generate strong vibration, forming a resonant impact with the insertion block. The triple action works together to peel off stubborn dust, and the cleaning is thorough and without dead corners.

[0015] 4. The staggered rotation design of the filter plate and the blocking plate in the suction assembly of this invention not only achieves scraping and cleaning of the mounting bracket, but also actively changes the airflow pressure distribution inside the cabinet by selectively blocking the exhaust channel through the blocking plate. When the exhaust channel is blocked, the gas with increased pressure reverses and blows back to clean the filter ring through the guide channel, realizing the recovery and utilization of airflow energy. It completes the self-cleaning of the auxiliary filter element without the need for an additional power source, further improving the integration and energy-saving level of the device.

[0016] 5. The filter assembly of this invention adopts a movable plate pull-out installation. The guide tube, filter cartridge and matching frame are all threaded and detachable, which makes the replacement and maintenance of filter media extremely convenient and quick, greatly shortening the equipment downtime for maintenance. At the same time, the support tube, as an elastic buffer element, provides flexible support for the sliding of the filter cartridge, ensuring the smooth movement of the filter cartridge and avoiding rigid collisions. Combined with the elastic positioning of the mounting strip by the constraint ring, the entire dust removal action is carried out smoothly under flexible constraints, improving the stability and reliability of the device in long-term operation.

[0019] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example: Figure 1 and Figure 2As shown, a flexible dust removal device based on differential pressure and filter load feedback includes a cabinet 1, which is hollow inside and has multiple inspection doors on its side. An air inlet pipe 11 is fixedly connected through the side of the cabinet 1, and an exhaust pipe 12 is fixedly connected through the upper side of the cabinet 1. A dust collection cabinet 13 is movably installed on the lower inner side of the cabinet 1. The dust collection cabinet 13 is a rectangular box with a hollow upper side. A suction assembly 2 and a filter assembly 3 are installed on the inner side of the cabinet 1 above the dust collection cabinet 13. The suction assembly 2 is used for air extraction. To guide gas flow, the filter assembly 3 is used for flexible filtration of gas and has an adaptive dust removal function. An air tank 4 is installed through the side of the cabinet 1. An air jet pipe 41 is installed at equal intervals between the suction assembly 2 and the filter assembly 3. The air jet pipe 41 is a hollow round pipe with a round hole on the side. A connecting pipe 42 is fixedly connected at equal intervals to the side of the air tank 4 and extends into the air jet pipe 41. Gas is delivered through the air tank 4, through the connecting pipe 42, and into the air jet pipe 41, so that the air jet pipe 41 can perform active dust removal operation by blowing air.

[0021] like Figures 2 to 4 As shown, the suction assembly 2 includes a fixing plate 21, which is fixedly installed on the inner side of the cabinet 1. The fixing plate 21 is a rectangular plate with round holes on the side. A mounting bracket 22 is fixedly installed on the upper side of the fixing plate 21. The mounting bracket 22 is a circular bracket with a hollowed-out lower side. Exhaust slots 23 are equidistantly arranged in a circular array on the side of the mounting bracket 22. The exhaust slots 23 are arc-shaped slots. A fan impeller 24 is arranged inside the mounting bracket 22. A motor 25 is fixedly connected to the side of the fan impeller 24 and is fixedly installed on the upper side of the fixing plate 21 by a bracket. A connecting bracket 26 is fixedly installed on the lower side of the fan impeller 24. The connecting bracket 26 is a "snowflake" bracket. Filter plates 27 are fixedly arranged in a circular array on the side of the connecting bracket 26 and are attached to the inner side of the mounting bracket 22. The connecting frame 26 has a curved plate made of activated carbon. A blocking plate 28 is fixedly installed in a circular array on the side of the connecting frame 26, and the blocking plate 28 is attached to the inner side of the mounting frame 22. The blocking plate 28 and the filter plate 27 are staggered and fixedly connected. The blocking plate 28 is a curved plate. Specifically, the motor 25 drives the fan impeller 24 to rotate, which performs the exhaust operation, drawing in and guiding the gas, accelerating the airflow. Simultaneously, the rotation of the fan impeller 24 drives the connecting frame 26 to rotate synchronously. The connecting frame 26 also drives the filter plate 27 and the blocking plate 28 to rotate. The filter plate 27 and the blocking plate 28 can scrape and clean the inner side of the mounting frame 22. When the filter plate 27 corresponds to the exhaust channel 23, the gas flows out of the exhaust channel 23 and is deodorized and purified by the filter plate 27. When the blocking plate 28 corresponds to the exhaust channel 23, the blocking plate 28 can seal the exhaust channel 23.

[0022] like Figures 5 to 10As shown, the filter assembly 3 includes a movable plate 31, which is slidably installed on the inner side of the cabinet 1. The movable plate 31 is a rectangular plate, and slots 311 are equally spaced on its side. The slots 311 are threaded circular grooves with a convex cross-section. A guide tube 32 is threadedly installed on the inner side of the slots 311, and part of the guide tube 32 extends downward out of the interior of the movable plate 31. The guide tube 32 is a stepped annular cylinder with threads on its inner and outer sides. A mating frame 321 is threadedly installed on the inner side of the guide tube 32. The mating frame 321 is a concave annular frame with threads on its outer side. The mating frame 321 mates with the inner thread of the guide tube 32. A mating groove 323 is equally spaced in a circular array on the side of the mating frame 321. A support tube 322 is fixedly connected to the lower side of the mating frame 321. The support tube 322 is an elastic bellows. A filter cylinder 33 is provided on the lower side of the support cylinder 322 and is slidably installed against the inner side of the guide cylinder 32. The filter cylinder 33 is a cylindrical cylinder with a hollow upper side. Filter holes 331 are equidistantly and obliquely opened on the side of the filter cylinder 33. The filter holes 331 are cylindrical holes. Specifically, during installation, the movable plate 31 is first pulled out of the cabinet 1. Then, the guide cylinder 32 is threaded into the slot 311. The filter cylinder 33 is then slidably inserted into the inner side of the guide cylinder 32. The mating bracket 321 is then threaded into the inner side of the guide cylinder 32, so that the support cylinder 322 is pressed against the upper side of the filter cylinder 33. After installation, the movable plate 31 is pushed back into the cabinet 1. After the gas enters from the air inlet pipe 11, it is filtered through the filter holes 331, passes through the inside of the guide cylinder 32 to the inside of the mounting bracket 22, and is discharged from the exhaust groove 23 and then collected and discharged from the exhaust pipe 12. A mounting plate 34 is movably disposed on the inner side of the mating frame 321. The mounting plate 34 is a circular ring frame. Mounting grooves 341 are equidistantly arranged in a circular array on the side of the mounting plate 34 corresponding to the mating grooves 323. The mounting grooves 341 are rectangular grooves. Constraint rings 342 are symmetrically fixedly connected between the two sides of the mounting plate 34 and the inner side of the mating frame 321. The constraint rings 342 are circular rings made of elastic material. Mounting strips 35 and constraint strips 353 are movably mounted inside the mounting grooves 341 and are interlocked. Mounting strips 35 and 353 are rectangular strips with a convex cross-section. Connectors 352, made of rubber, are fixedly fixedly mounted at equal intervals on the side of the mounting strips 35. Insertion blocks 351 are fixedly mounted on the side of the connectors 352. The insertion block 351 is inserted into the filter hole 331. The insertion block 351 is a conical block. Specifically, after the filter cartridge 33 is installed, the mounting strip 35 is first inserted into the mounting groove 341. After the insertion block 351 corresponds to the position of the filter hole 331, the constraint strip 353 is engaged with the mounting strip 35. The constraint strip 353 squeezes the mounting strip 35, causing the insertion block 351 to be inserted into the filter hole 331. At the same time, the constraint strip 353 deforms accordingly. When dust accumulates on the side of the filter hole 331, the airflow is guided by the guide tube 32, so that the airflow can push the filter cartridge 33 to slide upward. The filter cartridge 33 squeezes the support tube 322 to deform. At the same time, the insertion block 351 gradually slides out inside the filter hole 331. The insertion block 351 can then perform the dust cleaning operation on the filter hole 331. At the same time, the gas can continue to be discharged from the side of the insertion block 351. The guide tube 32 has circumferentially arrayed guide grooves 36 extending through it. Each guide groove 36 is a cylindrical cavity with a continuous cross-shaped cross section. A movable block 361, a frustum-shaped block, is movably installed inside the guide groove 36. A support spring 362 is fixedly connected between the side of the movable block 361 and the wall of the guide groove 36. A guide rod 363, a cylindrical rod, is fixedly installed on the side of the movable block 361, penetrating the guide tube 32 and fitting against the side of the filter cartridge 33. A filter ring 37, a circular plate with multiple holes on its surface, is fixedly installed on the lower side of the guide tube 32. Specifically, during normal use, the motor 25 drives the fan impeller 24 through a continuous... When the connecting frame 26 drives the blocking plate 28 to correspond with the exhaust groove 23, the exhaust groove 23 is blocked and the gas is discharged. The unidirectional gas delivery pressure increases, and the gas can flow in from the upper end of the guide groove 36, pushing the movable block 361 to pull the support spring 362 to deform, and the gas can flow downwards. This allows the filter ring 37 to be backflushed and cleaned. In addition, when the filter hole 331 is blocked and the filter cylinder 33 is pushed upward by the gas, the filter cylinder 33 changes the limiting position of the guide rod 363. The movable block 361 can slide down to the protrusion of the guide groove 36 when the support spring 362 elastically pulls it back to its original position. At this time, the gas can be filtered by the filter ring 37 and flow upward through the guide groove 36, avoiding the continuous accumulation of gas and excessive pressure inside the cabinet 1.

[0023] like Figure 5 , Figure 6 and Figure 10 As shown, an auxiliary component 5 is provided inside the filter assembly 3. The auxiliary component 5 includes a vibrating ring 51, which is located inside the mounting plate 34. The vibrating ring 51 is a circular ring frame. A rotating block 52 is rotatably mounted inside the vibrating ring 51. The rotating block 52 is a cylindrical shaft with fan blades evenly spaced on its side. An elastic strip 53 is fixedly connected at equal intervals between the outer side of the vibrating ring 51 and the inner side of the mounting plate 34. The elastic strip 53 is a cylindrical rod made of elastic material. Specifically, during normal use, after the gas is filtered by the filter holes 331, it can blow the rotating block 52 to rotate slowly. The rotation of the rotating block 52 drives the vibrating ring 51 to produce slight vibration, which is transmitted through the elastic strip 53 to drive the mounting plate 34 to rotate on the mating frame 321. The inner side vibrates, and the synchronous installation strip 35 and constraint strip 353 resonate as a whole. The insertion block 351 can then vibrate inside the filter hole 331, which can further enhance the unblocking effect of the filter hole 331 and achieve the appropriate dust removal operation. In addition, when the filter hole 331 is blocked, when the gas flows upward inside the guide channel 36, the gas tank 4 is triggered to perform active gas supply operation. The high-pressure gas is ejected through the connecting pipe 42 to the jet pipe 41 and blows the center position of the guide tube 32 to achieve the reverse blowing dust removal operation of the filter hole 331. The synchronous rotating block 52 is blown by the high-pressure gas and rotates faster, causing the vibrating ring 51 to vibrate more, and the insertion block 351 assists in cleaning the inside of the filter hole 331.

[0024] Working principle: During installation: Open the inspection doors on the side of cabinet 1 in sequence, perform routine checks on each component, and then pull the movable plate 31 out of the cabinet 1. First, thread the guide cylinder 32 into the slot 311. Then, slide the filter cylinder 33 into the inner part of the guide cylinder 32 until it reaches its lowest inner end. The filter cylinder 33 will then press the guide rod 363, causing the movable block 361 to pull the support spring 362 and deform. At this time, the movable block 361 will block the guide groove 36. Then, thread the mating bracket 321 with the mounting plate 34 on the inner side into the inner part of the guide cylinder 32. The lower support cylinder 322 of the frame 321 is attached to the upper side of the filter cylinder 33. Finally, the mounting strip 35 is inserted into the mounting plate 34 through the mating groove 323, so that the insertion block 351 corresponds to the filter hole 331. Then, the constraint strip 353 is slidably engaged with the mounting strip 35. The constraint strip 353 presses against the mounting strip 35, causing the insertion block 351 to be inserted into the filter hole 331. The connector 352 itself undergoes a mating deformation. After the installation of each component is completed, the movable plate 31 is pushed into the cabinet 1 as a whole, and the side inspection door of the cabinet 1 is closed for use. During normal use: Dust-laden gas is conveyed through the air inlet pipe 11, while the motor 25 drives the fan impeller 24 to rotate continuously, similar to the operation of an exhaust fan, which draws in the gas for rapid flow. After passing through the side of the filter cartridge 33, the gas is filtered through the filter holes 331 and then flows into the inner position of the mounting bracket 22. As the fan impeller 24 continues to rotate, the connecting bracket 26 drives the filter plate 27 and the blocking plate 28 to rotate continuously. When the filter plate 27 corresponds to the position of the exhaust groove 23, the gas passes through the filter plate 27 and is discharged from the exhaust groove 23. The filter plate 27 can further purify the gas, and the collected gas can be discharged from the exhaust pipe 12. Among them, the gas filtered through the filter hole 331 can blow the rotating block 52 to make it rotate slowly. The rotating block 52 drives the vibrating ring 51 to vibrate slightly. In this way, the elastic strip 53 and the mounting plate 34 can drive the mounting strip 35 and the constraint strip 353 to resonate. The insertion block 351 vibrates inside the filter hole 331 to generate auxiliary dust cleaning operation. During passive cleaning, as the filter holes 331 become clogged with dust, the pressure exerted by the gas on the filter cartridge 33 increases. When the filter holes 331 become clogged to a certain extent, the airflow is guided by the guide tube 32, and the filter cartridge 33 can be pushed upward inside the guide tube 32. At this time, the filter cartridge 33 squeezes and deforms the support tube 322, and the insertion block 351 is inserted and slid out into the filter hole 331, thus completing the unblocking and cleaning of the corresponding filter hole 331. During active cleaning: When the filter hole 331 is completely blocked, the filter cartridge 33 slides upward continuously, changing the limiting position of the guide rod 363. Under the elastic reset pull of the support spring 362, the guide groove 36 loses the restriction of the block 361, and the gas can flow upward through the inside of the guide groove 36, avoiding the filter hole 331 from being blocked and the gas pressure continuously too high. After maintaining this state for a certain period of time, the flow rate detection module inside the guide channel 36 triggers the gas tank 4 to supply gas. The gas tank 4 supplies high-pressure gas, which is discharged from the jet pipe 41 and blows the center of the guide tube 32. In this way, the high-pressure gas can backflush and clean the filter hole 331. At the same time, the high-pressure gas blows the rotating block 52 to rotate at high speed, causing the vibrating ring 51 to vibrate significantly. The insertion block 351 can then resonate and work together to clean and unblock the filter hole 331. The other motor 25 drives the connecting frame 26 so that the blocking plate 28 corresponds to the position of the exhaust groove 23. The exhaust groove 23 is blocked, and the gas on the upper side of the movable plate 31 accumulates to a certain extent and generates pressure. The pressurized gas can then flow in from the upper end of the guide groove 36, pushing the movable block 361 downward to pull the support spring 362. The gas is discharged downward through the guide groove 36 in one direction, which triggers the backflushing and dust removal operation of the filter ring 37.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
