Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and in particular to a filter cartridge dust collector with a synergistic dust cleaning function and a dust removal method. Background Art

[0002] Industrial and mining production processes generate large amounts of dust, potentially posing a threat to the surrounding environment and human health. Dust removal is essential to reduce dust concentrations in industrial and mining workplaces. Dry dust removal, which removes dust in a dry form, is widely used in industrial and mining applications, such as mechanical casting and coal preparation, due to its simple structure, low operational requirements, and its ability to centralize dust treatment and comprehensive utilization.

[0003] In workplaces with high dust concentrations, the filter cartridges collect dust too quickly, requiring frequent cleaning. This shortens the service life of the filter cartridges and increases the operating costs of the dust removal device. In addition, pulse jet cleaning processes cause a slow settling rate of dust particles, allowing high-concentration dust to permeate the dust removal system. This not only reduces dust removal efficiency but also makes explosions more likely to occur, increasing safety risks for the dust removal system. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a filter cartridge dust collector and a dust removal method with a synergistic cleaning function, which can not only realize multi-stage dust removal of dust particles, reduce the dust removal pressure of the filter cartridge, increase the service life, and save costs, but also realize the function of atomization and generating downward airflow during the operation of the dust removal program, thereby accelerating the cleaning speed of the dust collector and reducing the cleaning time; the booster nozzle of the present invention adopts an induced boosting method, which increases the blowing pressure of the blowing airflow and reduces the cost of the blowing device; the various components are all simple mechanical operations, the equipment is simple, and the degree of automation is high, which can effectively realize multi-stage processing of dust particles and improve the dust removal efficiency of the dust removal device.

[0005] To achieve the above-mentioned object, the present invention provides a filter cartridge dust collector with a synergistic dust cleaning function, comprising a dust collector housing, an induced pressurized pulse jet device and a vibration-assisted dust cleaning filter cartridge installed in the dust collector housing; the induced pressurized pulse jet device is located on the upper portion of the vibration-assisted dust cleaning filter cartridge and is used to eject high-speed airflow pulses to clean the dust accumulated inside the dust collector;

[0006] The induced pressurized pulse jet device includes an air delivery pipe, a nozzle support frame, an upper cover, a first-stage reducer, a nozzle support body, a connecting nut, and a second-stage reducer; the air delivery pipe is arranged in the dust collector box and is connected to a branch nozzle;

[0007] The end of the branch nozzle away from the gas pipe is inserted into the upper cover through the top wall opening of the upper cover, and the inner diameter of the top wall opening of the upper cover is larger than the outer diameter of the branch nozzle, so that a first annular gap air inlet hole is left at the connection between the branch nozzle and the upper cover;

[0008] The end of the upper cover away from the branch nozzle is inserted into the nozzle support body; the nozzle support body is connected and fixed to the nozzle support frame, and the nozzle support frame is fixed to the outer wall of the gas pipeline;

[0009] The first-stage reducer is inserted into the nozzle support body, and the top end of the first-stage reducer is hooked on the inner step surface of the nozzle support body; the inner diameter of the first-stage reducer decreases in the direction away from the nozzle support body; the end of the nozzle support body away from the upper cover body is inserted into the connecting nut and connected to the inner wall nut of the connecting nut;

[0012] Furthermore, the guide body includes a guide base, a contracted neck and a guide head that are integrally connected and fixed. The guide base is fixed to the inner bottom surface of the filter cartridge. The guide base and the guide head are both frustum-shaped, and the outer diameters of the two increase in the direction away from the induced boost pulse injection device. The top of the guide head forms a hemispherical surface.

[0013] Furthermore, two vibrating plates are hinged on the shrinking neck, and the two vibrating plates are symmetrically arranged on both sides of the axial direction of the shrinking neck. A spring rope is fixedly connected to the upper surface of each vibrating plate, and the end of the spring rope away from the vibrating plate is fixedly connected to the bottom side of the outer wall of the guide head.

[0014] Furthermore, the arc ring adopts a hollow design, and the arc ring is composed of two arc-shaped tubes, with a gap left between the ends of the two arc-shaped tubes.

[0015] Furthermore, a plurality of annular dust collecting baffles are sleeved on the outer side of the vibration-assisted dust cleaning filter cartridge, and the annular dust collecting baffles are evenly arranged along the height direction of the filter cartridge, and the annular dust collecting baffles adopt a circular ring design with an outer diameter gradually decreasing from top to bottom;

[0016] The annular dust collecting baffle includes an inclined groove baffle and an annular pleated filter; the inclined groove baffle is located on the outside of the annular pleated filter, and the inclined groove baffle is composed of a first vertical baffle, an inclined baffle and a second vertical baffle connected in sequence, and works together with the annular pleated filter to form a dust collecting cavity.

[0017] Furthermore, a plurality of supporting columns are provided on the inner side of the annular dust collecting baffle, and the plurality of supporting columns are evenly distributed along the circumference of the annular dust collecting baffle; each annular dust collecting baffle is fixedly connected to the supporting column; the supporting column is a hollow tube body, and the outer wall of the supporting column is provided with blowing holes at the position corresponding to the dust collecting cavity formed by each inclined groove baffle and the annular pleated filter, and the top end of the supporting column is connected to the blowing channel.

[0018] Furthermore, an atomization device is provided on the outside of the annular dust collecting baffle, and the atomization device includes a condensation net and a water mist baffle. A water mist inlet for supplying water mist is opened on the dust collector box. The water mist at the water mist inlet is a direct-discharge supply water mist. The water mist baffle is arranged on one side of the water mist inlet and fixed to the bottom surface of the mounting plate.

[0019] Furthermore, it also includes a negative pressure device, which includes a negative pressure fan, a filter, a pressure controller and a mounting pipe. A negative pressure port for installing the negative pressure device is opened at the bottom of the side wall of the dust collector case. The filter is fixed at the negative pressure port. The negative pressure fan is located on the side of the filter away from the dust collector case. The mounting pipe is fixedly connected to the outer wall of the dust collector case at the negative pressure port. The negative pressure fan is rotatably connected in the mounting pipe, and the negative pressure fan has forward and reverse functions to adapt to different working requirements. The pressure controller is fixed in the mounting pipe and electrically connected to the negative pressure fan.

[0020] The present invention also provides a dust cleaning and dust removal method for a filter cartridge dust collector with a synergistic dust cleaning function, which uses the filter cartridge dust collector with a synergistic dust cleaning function;

[0021] When the dust collector is performing adsorption dust removal, the induced draft fan connected to the air inlet draws the dust-laden airflow into the air inlet of the dust collector box and moves toward the vibration-assisted dust-cleaning filter cartridge; the dust-laden airflow first contacts the annular dust collecting baffle, and some dust particles are captured and adsorbed by the annular pleated filter screen; the remaining dust particles that cannot be captured by the annular pleated filter screen move between the intervals of the annular dust collecting baffles to the filter material surface of the vibration-assisted dust-cleaning filter cartridge, and then further adsorb and remove the dust particles in the dust-laden air;

[0022] When it is necessary to clean the dust inside the dust collector, the high-speed jet airflow enters the induced boost pulse jet device through the air pipe. The high-speed jet airflow first enters the cavity composed of the upper cover, the first-level reducer and the nozzle support body, and then generates negative pressure to form a first-level induced airflow boost; the jet airflow increases the jet flow through the induced airflow, and then accelerates the airflow through the first-level reducer; the jet airflow that completes the first-level boost acceleration flows from the first-level reducer into the second-level reducer, and the flow of high-speed airflow also generates negative pressure in the cavity of the second-level reducer. The external airflow is forced to enter the secondary reducer through the second annular slit air inlet on the secondary reducer, and then the secondary induced airflow merges with the primary induced airflow to complete the secondary pressurization and acceleration of the jet airflow, and finally sprayed from the secondary reducer to the vibration-assisted cleaning filter cartridge; under the guidance of the guide body, the high-speed jet airflow is ejected toward the vibration plate, and under the impact of the jet airflow, the vibration plate beats the arc ring downward to generate vibration and transmit it to the hollow circular tube, and then drives the filter cartridge to vibrate through the hollow circular tube, shaking off and removing the dust particles attached to the outer surface of the filter cartridge;

[0023] At the same time, the blowing channel in the annular dust collecting baffle also introduces the blowing airflow into the supporting column. The blowing airflow enters the dust collecting cavity formed by the oblique groove baffle and the annular pleated filter through the blowing hole, completing the cleaning of the dust particles attached to the annular pleated filter.

[0024] A portion of the dust particles sprayed down from the filter cartridge and the annular pleated filter screen will fall onto the inclined groove baffle and slide into the atomizing device by gravity, and be discharged in the form of muddy water. The remaining dust particles that are not captured by the atomizing device will sink rapidly under the action of the negative pressure device. Most of the dust particles will mix with the muddy water at the bottom of the dust collector box, while the remaining small part of the dust particles will be captured by the filter screen of the negative pressure device. The muddy water accumulated at the bottom of the dust collector box is discharged and regulated through the drainage device.

[0025] In addition, when the dust collector is performing adsorption dust removal, the negative pressure device can perform backblowing to clean the dust particles attached to the filter; the induced draft fan connected to the air inlet only operates during the adsorption dust removal stage, and the negative pressure device only operates during the cleaning stage to extract air flow and backblow to clean the circular filter.

[0026] Beneficial effects of the present invention:

[0027] The present invention provides a cartridge dust collector with a synergistic cleaning function. By setting an induced pressurized pulse jet device, a high-speed jet airflow passes through the induced pressurized pulse jet device, forming a negative pressure in its internal cavity, and inducing the external airflow to enter the pulse jet device through the first annular gap air inlet hole and the second annular gap air inlet hole, thereby effectively enhancing the jetting speed and pressure of the jetting airflow, and further improving the jet cleaning effect.

[0028] By setting up a vibration-assisted cleaning filter cartridge, high-speed pulse jet airflow drives the vibration plate to vibrate and knock the arc ring, and transmits the vibration force to the hollow circular tube. The vibration is then extended to the entire filter cartridge through the resonance effect of the hollow circular tube, removing dust particles attached to the filter material, thereby maintaining the filter cartridge in good working condition and improving the filtration efficiency.

[0029] By setting up an annular dust collection baffle, which cooperates with the vibration-assisted cleaning filter cartridge, a multi-stage dust removal and filtration effect is achieved in the dust removal stage, ensuring that most of the dust in the final airflow is effectively removed; the dust removal process ensures that the dust collector can perform dust removal efficiently and stably through the synergistic effect of the two, ensuring the normal operation of the equipment and the continuous purification of air quality.

DETAILED DESCRIPTION

[0042] The present invention will be further described in detail below with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0043] The invention discloses a filter cartridge dust collector with a synergistic dust cleaning function.

[0044] Reference Figure 1 and Figure 2 , a filter cartridge dust collector with a synergistic and efficient cleaning function, comprising an induced boost pulse jet device 1, a vibration-assisted dust cleaning filter cartridge 2, an annular dust collecting baffle 3, a negative pressure device 4, a dust collector box 5, an atomizing device 6 and a drainage device 7; wherein, the induced boost pulse jet device 1, the vibration-assisted dust cleaning filter cartridge 2, the annular dust collecting baffle 3 and the atomizing device 6 are all installed in the dust collector box 5, and an air inlet 52 and an air outlet 51 are provided on the outer wall of the dust collector box; the negative pressure device 4 and the drainage device 7 are installed at the bottom of the side wall of the dust collector box 5; the induced boost pulse jet device 1 is located at the top of the vibration-assisted dust cleaning filter cartridge 2, the annular dust collecting baffle 3 is arranged on the outside of the vibration-assisted dust cleaning filter cartridge 2, and the atomizing device 6 is located on the outside of the annular dust collecting baffle 3.

[0045] Reference Figure 3 and Figure 4 The induced pressurized pulse jet device 1 is installed on the upper part of the dust collector housing 5 and is used to eject high-speed airflow pulses to clean the dust accumulated inside the dust collector. The induced pressurized pulse jet device 1 includes an air supply pipe 11, a nozzle support frame 12, an upper cover 13, a first-stage reducer 14, a nozzle support body 15, a connecting nut 16, and a second-stage reducer 17. A jet mounting hole 54 is opened at the top of the outer wall of the dust collector housing. The air supply pipe 11 is installed in the dust collector housing 5 from the outside through the jet mounting hole 54 and is connected to a branch nozzle 111.

[0046] Reference Figure 3 and Figure 4 The end of the branch nozzle 111 away from the gas pipe 11 is passed through the top wall opening of the upper cover body 13, and the inner diameter of the top wall opening of the upper cover body 13 is larger than the outer diameter of the branch nozzle 111, so that a first annular seam air inlet hole 18 is left at the connection between the branch nozzle 111 and the upper cover body 13; the end of the upper cover body 13 away from the branch nozzle 111 is passed through the nozzle support body 15; the two sides of the nozzle support body 15 are connected to the nozzle support frame 12 by bolts, and corresponding connection holes 19 for the bolts to pass through are opened on the nozzle support body 15 and the nozzle support frame 12, and the nozzle support frame 12 is welded and fixed to the outer wall of the gas pipe 11. The first-stage reducer 14 is passed through the nozzle support body 15, and the top end of the first-stage reducer 14 is hung on the inner step surface of the bottom end of the nozzle support body 15; the inner diameter of the first-stage reducer 14 decreases in the direction away from the nozzle support body 15; the end of the nozzle support body 15 away from the upper cover body 13 is passed through the connecting nut 16 and is connected to the inner wall nut of the connecting nut 16; the top end of the second-stage reducer 17 is sleeved on the outside of the first-stage reducer 14, and the top end of the second-stage reducer 17 is passed through the connecting nut 16 and is threadedly connected to the inner wall of the connecting nut 16; the outer circumferential surface of the second-stage reducer 17 is provided with a second annular seam air inlet hole 110, which is composed of two arc-shaped air inlet holes.

[0047] The high-speed jet airflow enters through the air delivery pipe 11 and rapidly enters the interior of the induced supercharged pulse jet device 1. It first enters the cavity formed by the upper cover 13, the first-stage convergent tube 14, and the nozzle support 15, creating a negative pressure within the cavity. This negative pressure induces external airflow to enter the cavity through the first annular gap air inlet 18 between the air delivery pipe 11 and the upper cover 13, further increasing the pressure of the jet airflow.

[0048] Subsequently, the primary induced airflow and the high-speed injection airflow flow together from the primary reducer 14 into the secondary reducer 17. At this point, the high-speed airflow flows through the interior of the secondary reducer 17, creating a negative pressure there. This in turn forces the external airflow to flow into the secondary reducer 17 through the second annular gap therein. The secondary induced airflow then merges with the primary induced airflow, further increasing the flow rate and velocity of the injection airflow, thereby significantly enhancing the injection capability of the pulse injection device.

[0049] Reference Figure 3 and Figure 4 To ensure a tight connection and stable operation of all components, a connecting nut 16 securely connects the nozzle support body 15 to the secondary reducer 17. Simultaneously, the upper cover 13 and the primary reducer 14 fit into the stepped groove of the nozzle support body 15, ensuring the stability of all components within the device. The bolted connection between the nozzle support body 15 and the nozzle support frame 12 ensures the overall robustness of the device and the unobstructed airflow path, further enhancing the effectiveness and safety of the spray system.

[0050] Reference Figures 5 to 7 A mounting plate 55 is horizontally welded and fixed inside the dust collector housing 5. A notch 56 is provided in the middle of the mounting plate 55 for mounting the vibration-assisted dust-cleaning filter cartridge 2. The vibration-assisted dust-cleaning filter cartridge 2 includes a filter cartridge 26, a plurality of hollow circular tubes 21, an arc ring 24, and a flow guide 22. The hollow circular tubes 21, the arc ring 24, and the flow guide 22 are all located inside the filter cartridge 26. The filter cartridge 26 is inserted into the mounting plate 55 through the notch 56, and the top end of the filter cartridge 26 is mounted and bolted to the mounting plate 55.

[0051] Reference Figures 5 to 7 The hollow circular tube 21 is vertically arranged on the inner filter surface of the filter cartridge 26. In this embodiment, there are four hollow circular tubes 21, which are evenly distributed along the circumference of the filter cartridge 26. The outer wall of the hollow circular tube 21 is fitted and fixed to the inner filter surface of the filter cartridge 26. The distance between the upper and lower ends of each hollow circular tube 21 and the top and bottom of the filter cartridge 26 is 10 mm to ensure that the hollow circular tube 21 can be stably fixed in the filter cartridge 26 without affecting the function of its components during the cleaning process.

[0052] Reference Figures 5 to 7 The arc ring 24 is coaxially arranged with the filter cartridge 26. The arc ring 24 is located in the middle of each hollow circular tube 21. The outer wall of the arc ring 24 is fixedly connected to the four hollow circular tubes 21. The arc ring 24 is composed of two arc-shaped tube bodies. The ends of the two arc-shaped tube bodies are separated by a gap of 15 mm. The arc ring 24 also adopts a hollow design, so that it can vibrate under the impact of the high-speed pulse jet airflow and can effectively transmit the vibration force to the hollow circular tube 21. The design of the arc ring 24 not only enhances the vibration conduction effect, but also improves the vibration efficiency during the entire cleaning process, making the cleaning more thorough.

[0053] Reference Figures 5 to 7 The guide body 22 includes a guide base 221, a contracted neck 222, and a guide head 223 that are integrally connected and fixed. The guide base 221 is fixed to the inner bottom surface of the filter cartridge 26. The guide base 221 and the guide head 223 are both truncated cone-shaped, and the outer diameters of both increase in the direction away from the induced boost pulse jet device 1, and the inclination angle of the outer walls of both relative to the horizontal plane is 75°; the top of the guide head 223 forms a hemispherical surface; the design of the guide body 22 ensures that the pulse jet airflow can obtain the best dispersion and diversion effect, avoids excessive concentration of the airflow, thereby improving the utilization efficiency of the airflow and the cleaning effect. The inclination angle of the guide body 22 accurately controls the directionality of the airflow, so that the pulse jet airflow in the entire cleaning process can act on the filter cartridge 26 more evenly and efficiently, thereby better achieving the purpose of removing dust accumulation and increasing the service life of the filter element.

[0054] Reference Figures 5 to 7 Two rapping plates 25 are hinged on the contraction neck 222, and the two rapping plates 25 are symmetrically arranged on both sides of the axial direction of the contraction neck 222. A spring rope 23 is fixedly connected to the upper surface of each rapping plate 25, and one end of the spring rope 23 away from the rapping plate 25 is fixedly connected to the bottom side of the outer wall of the guide head 223. Under the action of the high-speed pulse jet airflow, the rapping plate 25 can vibrate up and down and knock the arc ring 24, causing the arc ring 24 to vibrate and transmit the vibration force to the hollow circular tube 21, and then the vibration is extended to the entire filter cartridge 26 through the resonance effect of the hollow circular tube 21; these vibration fluctuations help remove dust particles attached to the filter material, thereby maintaining the good working condition of the filter cartridge 26 and improving the filtration efficiency.

[0055] Reference Figure 8 and Figure 9 There are several annular dust collecting baffles 3, which are evenly arranged along the height direction of the filter cartridge 26. The annular dust collecting baffles 3 adopt a circular ring design with an outer diameter gradually decreasing from top to bottom. The inner diameter of the annular dust collecting baffle 3 is slightly larger than the vibration-assisted cleaning filter cartridge 2. The annular dust collecting baffle 3 is sleeved on the outside of the vibration-assisted cleaning filter cartridge 2 to form an effective filtering space.

[0056] The annular dust collecting baffle 3 includes an inclined groove baffle 32 and an annular pleated filter 33; the inclined groove baffle 32 is located on the outside of the annular pleated filter 33, and the inclined groove baffle 32 is composed of a first vertical baffle 321, an inclined baffle 322 and a second vertical baffle 323 connected in sequence, and works together with the annular pleated filter 33 to form a dust collecting cavity, which effectively blocks the entry of dust particles.

[0057] In order to enhance the structural stability of the annular dust collecting baffle 3, a support column 34 is provided on the inner side of the annular dust collecting baffle 3. In this embodiment, there are four support columns 34, which are evenly distributed along the circumference of the annular dust collecting baffle 3; each annular dust collecting baffle 3 is fixedly connected to the support column 34, thereby improving the stability of the overall structure.

[0058] The support column 34 is a hollow tube. The outer wall of the support column 34 is provided with a blowing hole 35 at the position corresponding to the dust collecting cavity formed by each inclined groove baffle 32 and the annular pleated filter 33. The top of the support column 34 is connected to the blowing channel 31, thereby forming a system structure similar to pulse jet cleaning, which is convenient for the subsequent removal of dust on the annular pleated filter 33.

[0059] The inclined groove baffle 32 is tilted 30° relative to the horizontal plane. When the vibration-assisted cleaning filter cartridge 2 and the annular dust collection baffle 3 work together to clean the dust, the dust on the annular pleated filter screen 33 is removed and falls to the upper surface of the clamping groove baffle of the next layer. Due to the tilt of the inclined groove baffle 32, the dust particles slide downward at the inclined angle under the action of gravity and are further processed and discharged by the atomizing device 6 installed on the outside, preventing the particles from re-entering the filtration system.

[0060] During dust collector operation, a dust-laden airflow enters through air inlet 52. As the airflow flows, most of the dust particles in the dust-laden airflow are first captured and adsorbed by annular pleated filter 33. Dust particles that are not effectively captured during the initial filtration phase enter the vibration-assisted cleaning filter cartridge 2, where they are further adsorbed and removed by filter cartridge 26, ultimately ensuring that the majority of dust in the airflow is effectively removed. This synergistic effect of these two processes ensures that the dust collector can efficiently and stably remove dust, guaranteeing the normal operation of the equipment and the continuous purification of air quality.

[0061] Reference Figure 10 , the atomizing device 6 is arranged on the outside of the annular dust collecting baffle 3 on all sides. The atomizing device 6 includes a condensation net 63 and a water mist baffle 61. A water mist inlet 62 for supplying water mist is opened on the dust collector housing 5. The water mist of the water mist inlet 62 is a straight-discharge type of water mist supply. The water mist baffle 61 is arranged on one side of the water mist inlet 62 and is welded and fixed to the bottom surface of the mounting plate 55. The setting of the water mist baffle 61 can prevent the water mist from directly and straightly migrating toward the vibration-assisted dust cleaning filter cartridge 2. When the vibration-assisted dust cleaning filter cartridge 2 and the annular dust collecting baffle 3 are cleaning, the dust particles blown off will stay on the oblique groove baffle 32 and move to the atomizing device 6 arranged around it by gravity; the dust particles moving toward the atomizing device 6 will fall on the condensation net 63, and the water mist particles and condensed water droplets thereon will adsorb these dust particles, accelerating the removal of dust particles.

[0062] Reference Figure 1 and Figure 2 Dust particles ejected from the filter cartridge 26 and the annular pleated filter screen 33 partially fall onto the inclined grooved baffle 32 and slide into the atomizing device 6 by gravity, where they are discharged as muddy water. Two muddy water baffles 57 are fixed within the dust collector housing 5. These baffles 57 are symmetrically arranged and tilted downward, buffering and diverting the muddy water formed by dust adsorbed by the atomizing device 6. A drain port 53 is provided at the bottom of the dust collector housing 5, connected to a drainage device 7 for discharging the muddy water.

[0063] Reference Figure 1 The drainage device 7 includes a drainage pipe, a water pump and a liquid level sensor. The drainage pipe is connected to the interior of the dust collector box 5 through the drainage port 53. The water pump is installed on the drainage pipe. The liquid level sensor is installed at the bottom of the side wall of the dust collector box 5 to detect the liquid level of the muddy water. The liquid level sensor is electrically connected to the water pump. When there is too much muddy water in the dust collector box 5, the liquid level sensor is triggered, and the liquid level sensor transmits a signal to the water pump, thereby discharging the muddy water in the dust collector box 5.

[0064] Reference Figure 11 The negative pressure device 4 includes a negative pressure fan 42, a filter 43, a pressure controller 41, and a mounting tube 44. A negative pressure port 58 for mounting the negative pressure device 4 is provided at the bottom of the side wall of the dust collector housing 5. The filter 43 is fixed to the negative pressure port 58. The negative pressure fan 42 is located on the side of the filter 43 away from the dust collector housing 5. The mounting tube 44 is fixedly connected to the outer wall of the dust collector housing 5 at the negative pressure port 58. The negative pressure fan 42 is rotatably connected to the mounting tube 44 and has forward and reverse rotation functions to adapt to different working requirements. The pressure controller 41 is fixed to the mounting tube 44 and is electrically connected to the negative pressure fan 42.

[0065] In normal operation, negative pressure fan 42 draws air from the dust collector, generating negative pressure. This negative pressure effectively promotes the settling of dust particles within the dust collector, ensuring the system's dust removal efficiency. However, over time and with increasing workload, dust particles accumulate on the surface of filter 43, causing the filter's ventilation performance to deteriorate and, in turn, increasing the pressure difference between negative pressure fan 42 and filter 43. At this point, pressure controller 41 detects the pressure change and identifies blockage in filter 43, promptly activating the reverse function to reverse the flow of negative pressure fan 42. This reverse rotation of the fan clears dust particles adhering to filter 43, restoring normal air permeability and dust removal efficiency. Once the cleaning process is complete, the system monitors the pressure to return to its set normal value. When the pressure in filter 43 drops to a certain limit, pressure controller 41 controls negative pressure fan 42 to resume forward rotation, resuming normal negative pressure extraction operation. The entire process is precisely regulated by the pressure controller 41 to ensure that the dust collector maintains an efficient and stable working state during operation, effectively avoiding a reduction in dust removal efficiency due to dust accumulation.

[0066] The present invention also discloses a dust removal method for a cartridge dust collector with a synergistic dust cleaning function, which uses the cartridge dust collector with a synergistic dust cleaning function, and specifically includes the following steps:

[0067] When the dust collector is performing adsorption dust removal, the induced draft fan connected to the air inlet 52 draws the dust-laden air flow into the air inlet 52 of the dust collector box 5 and moves toward the vibration-assisted dust-cleaning filter cartridge 2; the dust-laden air flow will first contact the annular dust collecting baffle 3, and some dust particles will be captured and adsorbed by the annular pleated filter screen 33; the remaining dust particles that cannot be captured by the annular pleated filter screen 33 will move between the intervals of each annular dust collecting baffle 3 to the filter material surface of the vibration-assisted dust-cleaning filter cartridge 2, and then further adsorb and remove the dust particles in the dust-laden gas. The dual dust removal of the annular dust collecting baffle 3 and the vibration-assisted dust-cleaning filter cartridge 2 not only effectively improves the dust removal effect and ensures the cleanliness of the exhaust gas, but also effectively reduces the dust removal pressure of the filter cartridge 26, reduces the dust accumulation speed on the surface of the filter cartridge 26, reduces the frequency of cleaning inside the dust collector, and realizes long-term and efficient dust removal operations.

[0068] When cleaning the inside of the dust collector, a high-speed jet airflow enters the induced boost pulse jet device 1 from the air supply pipe 11, and the high-speed jet airflow first enters the cavity composed of the upper cover 13, the first-level reducer 14 and the nozzle support body 15, and the negative pressure generated forms a first-level induced airflow boost; the jet airflow increases the jet flow through the induced airflow, and then accelerates the airflow through the first-level reducer 14; the jet airflow that completes the first-level boost acceleration flows from the first-level reducer 14 into the second-level reducer 17, and the flow of high-speed airflow also generates a negative pressure in the cavity of the second-level reducer 17, prompting the external airflow to enter the second-level reducer 17 through the second annular seam air inlet 110 on the second-level reducer 17, and then the second-level induced airflow merges with the first-level induced airflow to complete the secondary boost acceleration of the jet airflow, and finally sprays from the second-level reducer 17 to the vibration-assisted cleaning filter cartridge 2. The high-speed jet airflow is guided by the guide body 22 and ejected toward the vibrating plate 25. Under the impact of the jet airflow, the vibrating plate 25 beats the arc ring 24 downward to generate vibration and transmits it to the hollow circular tube 21. Then, the hollow circular tube 21 drives the filter cartridge 26 to vibrate, shaking off and removing the dust particles attached to the outer surface of the filter cartridge 26.

[0069] At the same time, the blowing channel 31 in the annular dust collecting baffle 3 also introduces a blowing airflow into the supporting column 34. The blowing airflow enters the dust collecting cavity formed by the inclined groove baffle 32 and the annular pleated filter 33 through the blowing hole 35, completing the cleaning of the dust particles attached to the annular pleated filter 33.

[0070] Some of the dust particles blown off filter cartridge 26 and annular pleated filter screen 33 fall onto obliquely grooved baffle 32 and slide by gravity into atomizing device 6, where they are discharged as muddy water. Other dust particles not captured by atomizing device 6 quickly sink under the action of negative pressure device 4, with most of them mixing with the muddy water at the bottom of dust collector housing 5. A small portion of dust particles is captured by filter screen 43 of negative pressure device 4. The muddy water that accumulates at the bottom of dust collector housing 5 is discharged and regulated via drainage device 7.

[0071] In addition, when the dust collector is performing adsorption dust removal, the negative pressure device 4 can also perform backblowing in time to clean the dust particles attached to the filter 43; the induced draft fan connected to the air inlet 52 only operates in the adsorption dust removal stage, and the negative pressure device 4 only operates when extracting airflow and backblowing to clean the circular filter 43 in the dust cleaning stage.

[0072] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
