Description

Technical Field

[0001] This utility model belongs to the field of air filter technology, specifically, it relates to a dust removal system for air filters. Background Technology

[0002] Air filters are widely used in various mechanical equipment and vehicles. Their main function is to filter dust and impurities in the air to ensure that the air entering the equipment is clean, thereby reducing equipment wear and improving the service life and performance of the equipment. However, as the usage time increases, a large amount of dust will accumulate on the surface of the air filter, which will lead to a decrease in filtration efficiency, increase equipment energy consumption, and even affect the normal operation of the equipment.

[0003] Chinese patent CN212417267U discloses a dust removal device for air filters. The device uses a locking block composed of an arc-shaped sleeve, an internal soft pad, a connecting rod, a grooved shaft, and an adjusting bolt to secure the air filter for dust removal. The connecting rod is welded to a hollow metal cover, preventing it from easily falling off during use. To secure the filter, the user rotates the adjusting bolt, causing it to move within the connecting rod and rotate within the grooved shaft. This movement causes the arc-shaped sleeve to wrap around the air filter. The internal soft pad provides good protection and prevents slippage. However, this device uses a simple blowing method for dust removal. Due to uneven airflow distribution, it cannot effectively remove dust from every corner of the filter, resulting in unsatisfactory dust removal performance.

[0004] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] In human production and daily life, the development of air filtration dust removal systems is closely linked to industrial progress, constantly evolving to meet the ever-increasing demand for clean air. In the early days, industry was smaller in scale, and the requirements for air purification were relatively lower. At that time, people mainly relied on simple physical methods for dust removal, such as using filters to intercept larger dust particles. These filters were usually made of woven fabric or metal wire, with a simple structure and low cost, but their dust removal effect was limited; they could only handle some relatively coarse dust, and were powerless against fine particles.

[0030] With the advancement of the Industrial Revolution, factories expanded in scale, and dust pollution from production processes became increasingly serious. To address this challenge, mechanical dust collectors emerged. In 1885, the cyclone dust collector was put into use, utilizing centrifugal force to separate dust from the airflow. Dust-laden gas enters the collector tangentially and rotates within the outer cylinder. The dust is thrown against the cylinder wall by centrifugal force and then falls down. Compared to earlier filters, cyclone dust collectors could handle finer dust particles and had a higher processing capacity, leading to their widespread use in industrial production at the time. Subsequently, other mechanical dust collection devices, such as gravity settling chambers and inertial dust collectors, appeared. Gravity settling chambers reduce airflow velocity, allowing heavier particles to settle naturally under gravity; inertial dust collectors utilize the inertia of dust particles, causing the dust-laden airflow to collide with baffles or abruptly change direction, thus separating dust from the airflow. These mechanical dust collectors have alleviated industrial dust pollution to some extent, but their effectiveness in removing fine dust is still unsatisfactory.

[0031] Electrostatic precipitator (ESP) technology began to emerge in the late 19th and early 20th centuries. In 1824, the German scientist Hofferder completed the first demonstration device for electrostatic precipitator. Following a series of studies and improvements by scientists, in 1907, Professor Cotterell, a chemistry professor at the University of California, successfully applied ESP technology to the capture of sulfuric acid mist. The working principle of an ESP is to separate dust particles from the dust-laden gas by ionizing it through a high-voltage electric field. In the electrode system, a negative voltage is applied to the anode plate, creating a non-uniform electric field between the anode and cathode. When the electric field strength reaches a certain level, the gas is ionized, and the charged flue gas particles move towards the electrodes under the influence of the electric field force and are captured. ESPs have extremely high removal efficiency for fine dust and can handle high-temperature, high-concentration dust-laden gases. They have been rapidly and widely used in power plants, boilers, cement plants, steel plants, and other industries, becoming one of the important technologies in industrial dust removal.

[0032] In the mid-20th century, filtration dust collection technology experienced significant development. Baghouse dust collectors began to be used in industry in the 1780s, initially employing mechanical vibration cleaning, which was inefficient. In 1950, the reverse-air baghouse dust collector emerged, enabling continuous operation and significantly increasing the air handling capacity. In 1957, the pulse-jet baghouse dust collector was developed, which periodically injects high-pressure gas into the filter bags, causing them to expand instantaneously and shake off accumulated dust, greatly improving cleaning efficiency and dust collection effectiveness. Filtration dust collectors utilize the principle of filter materials intercepting dust particles to achieve separation. With technological advancements, filter materials have continuously improved, evolving from early natural fibers to glass fiber, polypropylene fiber, polyester fiber, and others. These materials possess characteristics such as good air permeability, light weight, and good processing performance, effectively intercepting dust particles of different sizes. Glass fiber, in particular, has become a core material for high-efficiency filters due to its excellent filtration effect on particles smaller than 10 micrometers, and is widely used in air purification.

[0033] During this period, wet scrubbers also saw development. Wet scrubbers utilize droplets, liquid films, and bubbles to separate dust particles from harmful gases in a dust-laden airflow. The contact forms between water and dust particles include droplets, water films, and bubbles. For example, spray towers use water droplets to capture dust, cyclone water film scrubbers increase the dust capture probability by forming a water film on the dust surface, and foam scrubbers rely on the interaction between bubbles and dust to achieve dust removal. Wet scrubbers primarily utilize inertial impaction for dust particles with a diameter of 1-5 micrometers, and diffusion and coagulation for dust particles smaller than 1 micrometer. They can effectively remove various types of dust and simultaneously remove harmful gases, finding applications in specific industries such as metallurgy and chemical processing.

[0034] Entering the 21st century, with the rapid development of technology and people's increasing demands for air quality, dust removal systems for air filters are evolving towards greater efficiency, intelligence, and environmental friendliness. Modern dust removal systems often integrate multiple advanced technologies, such as intelligent control systems that can adjust equipment operation in real time based on parameters like dust concentration and airflow speed, achieving precise control. Some new types of dust removal systems for air filters, like the aforementioned high-efficiency dust removal systems, utilize the synergistic effect of vibration and blowing components to quickly and thoroughly remove dust from the surface and interior of air filters, significantly improving dust removal efficiency compared to traditional single-method dust removal. Their fixing components can flexibly adapt to air filters of different sizes, and the air hoses can be flexibly adjusted for the spray angle, offering strong versatility. Simultaneously, the system adopts a modular design, resulting in a compact structure, easy maintenance, and environmentally friendly and energy-saving dust removal within a closed enclosure.

[0035] In the industrial sector, these advanced dust removal systems are widely used in various production processes, effectively reducing dust emissions and protecting worker health and the environment. In the civilian sector, such as in automotive engine air filters and indoor air purification equipment, advanced dust removal technology also provides people with a cleaner air environment. For example, automotive engine air filters employ highly efficient dust removal technology to effectively filter impurities in the air, ensuring normal engine operation and extending engine life. Indoor air purification equipment, through advanced dust removal systems, removes pollutants such as dust, pollen, and smoke from the air, improving indoor air quality and ensuring people's quality of life.

[0036] Looking back at the development of dust removal systems for air filters, from simple filters to today's highly integrated and intelligent advanced systems, each technological breakthrough has driven improvements in industrial production and the living environment. In the future, with continued technological advancements, it is believed that dust removal systems for air filters will achieve even greater breakthroughs in improving dust removal efficiency, reducing energy consumption, and expanding application areas, playing a greater role in creating a cleaner and healthier air environment.

[0037] Please see Figure 1-7 As shown, this embodiment provides a dust removal system for an air filter, including: a housing 1, which is divided into a dust removal chamber 14 and an ash storage chamber 13 by a partition 4; the dust removal chamber 14 is provided with a door 2, the ash storage chamber 13 is connected to a baffle 3, the top of the dust removal chamber 14 is connected to a connecting plate 7, the bottom of the connecting plate 7 is connected to an air pipe 8, the air pipe 8 is provided with multiple nozzles 9, the top of the partition 4 is connected to a workbench 5, the surface of the workbench 5 is connected to a fixing component, multiple through holes 17 are opened on both the left and right sides of the partition 4, an exhaust fan 20 is connected inside the ash storage chamber 13, and the exhaust fan 20 is located below the through holes 17; the bottom of the workbench 5 is provided with a vibration component, and the workbench 5 is connected to the partition 4 by bolts 15, with a gap between the top of the bolts 15 and the top surface of the workbench 5.

[0038] The connecting plate 7 at the top of the dust removal chamber 14 connects to the air pipe 8. Multiple nozzles 9 are distributed on the air pipe 8, enabling even gas spraying. The workbench 5 on the partition 4 is used to place the air filter, and the surface fixing components securely fix the filter. Through holes 17 on both sides of the partition 4 provide channels for dust to fall. The exhaust fan 20 in the dust storage chamber 13 is located below the through holes 17, facilitating dust discharge. The workbench 5 is connected to the partition 4 by bolts 15, with a gap between the top of the bolts 15 and the top surface of the workbench 5. Combined with the vibration component below, this allows for efficient airflow. The high-efficiency vibration dust collector has an air filter placed on the workbench 5 and fixed by a fixing component. An external air source supplies air to the air pipe 8 through the connecting plate 7. The air is sprayed onto the filter through the nozzle 9 to initially blow away the dust on its surface. At the same time, the vibration component is activated, causing the workbench 5 and the filter to vibrate, which loosens the dust. Under the action of airflow and gravity, the loosened dust falls into the dust storage chamber 13 through the through hole 17 on the partition 4. The exhaust fan 20 in the dust storage chamber 13 operates to discharge the dust from the housing 1 in a timely manner, completing the entire dust removal process.

[0039] In this embodiment, the fixing component includes clamping plates 6 located on the left and right sides of the surface of the workbench 5. A sliding groove 22 is provided on the surface of the workbench 5. A slider 23 corresponding to the sliding groove 22 is connected to the bottom end of the clamping plate 6. A lead screw 16 is connected inside the sliding groove 22. One end of the lead screw 16 is rotatably connected to the side wall of the sliding groove 22, and the other end passes through the side wall of the workbench 5 and is located outside the workbench 5. The lead screw 16 passes through the slider 23 and is threadedly connected to the slider 23.

[0040] When it is necessary to fix the air filter, the lead screw 16 located outside the worktable 5 is rotated. Since the lead screw 16 is threadedly connected to the slider 23, the slider 23 will move along the axis of the lead screw 16 within the slide groove 22, thereby causing the clamping plate 6 to slide on the surface of the worktable 5. The clamping plates 6 on the left and right sides move towards each other, which can stably clamp air filters of different sizes on the worktable 5, ensuring that the filter will not shake or shift during the dust removal process, thus providing a foundation for subsequent efficient dust removal.

[0041] The vibration assembly includes a rotating shaft 18 that passes through the partition 4. The surface of the rotating shaft 18 abuts against the bottom of the worktable 5. An eccentric block 19 is connected to the surface of the rotating shaft 18. One end of the rotating shaft 18 is rotatably connected to the inner wall of the housing 1, and the other end passes through the side wall of the housing 1 and is connected to the servo motor 12.

[0042] Servo motor 12 drives shaft 18 to rotate. Since eccentric block 19 is installed on the surface of shaft 18, the centrifugal force generated by eccentric block 19 will cause shaft 18 to vibrate periodically as shaft 18 rotates. The surface of shaft 18 abuts against the bottom of worktable 5. The vibration is transmitted to worktable 5 through shaft 18, which in turn drives the air filter placed on worktable 5 to vibrate. The dust will become loose under the action of vibration, and the binding force with the filter will be weakened, making it easier to be blown away by the subsequent airflow. Compared with traditional vibration mechanism, the vibration frequency and amplitude can be precisely controlled by servo motor 12 to adapt to the dust removal needs of different types of filters.

[0043] Telescopic rods 10 are connected to the left and right side walls of the dust removal chamber 14. The telescopic ends of the telescopic rods 10 are connected to limit plates 11. Both the limit plates 11 and the clamping plates 6 are arc-shaped. The arc shape of the limit plates 11 can better adapt to the outer contour of the filter, preventing the filter from shifting during vibration and purging, while avoiding hard squeezing damage to the surface of the filter.

[0044] The bottom of the connecting plate 7 is provided with multiple air tubes 8, which are evenly distributed. The air tubes 8 are connected to the connecting plate 7 through a rotating part 21. The rotating part 21 is spherical. Both the connecting plate 7 and the rotating part 21 are provided with air passages, which are connected to the air tubes 8.

[0045] The spherical rotating part 21 allows the air pipe 8 to rotate freely within a certain range to adjust its angle. During dust removal, the air pipe 8 can be flexibly rotated according to the shape, structure and dust adhesion of the air filter, so that the nozzle 9 on the air pipe 8 sprays high-pressure gas at the optimal angle, achieving precise blowing of various parts of the filter, making up for the limitations of fixed-angle blowing, and further improving the comprehensiveness and effectiveness of dust removal.

[0046] Working principle:

[0047] Place the air filter on the surface of the workbench 5 and rotate the lead screw 16 located outside the workbench 5. Since the lead screw 16 is threadedly connected to the slider 23, the slider 23 will move along the axis of the lead screw 16 in the slide groove 22, causing the clamping plates 6 on the left and right sides to slide towards each other, firmly clamping the filter. At the same time, the telescopic rods 10 on the left and right side walls of the dust removal chamber 14 can be adjusted and extended according to the height of the filter, so that the arc-shaped limiting plate 11 fits against the side of the filter, providing limiting support from the side, preventing the filter from shaking and shifting during subsequent processing, and laying the foundation for dust removal work.

[0048] An external air source supplies air to the air pipe 8 through the connecting plate 7. The air pipe 8 is connected to the connecting plate 7 through the spherical rotating part 21. The angle can be freely adjusted according to the shape of the filter and the dust distribution. Multiple nozzles 9 on the air pipe 8 spray high-pressure gas evenly onto the surface of the air filter to perform preliminary cleaning of the dust. The airflow impact force causes some of the dust to detach from the filter.

[0049] When the servo motor 12 starts, it drives the rotating shaft 18 that passes through the partition 4 to rotate. The eccentric block 19 on the surface of the rotating shaft 18 generates centrifugal force when rotating, causing the rotating shaft 18 to vibrate periodically. Since the surface of the rotating shaft 18 is in contact with the bottom of the worktable 5, the vibration is transmitted to the worktable 5, which in turn causes the filter to vibrate, further loosening the dust attached to the filter and weakening the binding force between the dust and the filter.

[0050] Under the combined action of gas purging and vibration, the loosened dust falls into the dust collection chamber 13 below through the through holes 17 on both sides of the partition 4, driven by the airflow and its own gravity. The exhaust fan 20 in the dust collection chamber 13 runs continuously to discharge the dust into the box 1 in a timely manner, thus completing the entire dust removal process.

[0051] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
