Description

Technical Field

[0001] This invention application relates to the field of baghouse dust collection technology, specifically to a high-efficiency cyclone baghouse dust collector. Background Technology

[0002] Baghouse dust collectors, commonly used dust purification equipment in industrial production, primarily function to separate dust-laden airflow from gas through filter bags, playing a crucial role in environmental protection and production safety. With the expansion of industrial production scale and increasingly stringent environmental protection requirements, higher demands are being placed on the dust removal efficiency, operational stability, and ease of maintenance of baghouse dust collectors.

[0003] Patent CN118698241B discloses a high-efficiency bag filter dust collector. Its working principle is as follows: After the dust-laden gas enters the collection hopper through the air inlet, larger dust particles settle into the dust collector by gravity, and the remaining dust-laden airflow enters the dust collector bags through the airflow distribution structure. As dust accumulates in the bags, an air pressure difference is formed between the bags and the shell. The pressure difference feedback component converts the air pressure difference into mechanical displacement through components such as the low-pressure detection tube, the pressure difference tube, and the moving piston. The moving plate in the airflow distribution structure is pulled by the pull wire, which in turn drives the rotating rod and the baffle plate to rotate, changing the effective flow area in the flow control box and realizing the secondary distribution of the dust-laden airflow. This allows the airflow to preferentially pass through the bags with less dust accumulation, balancing the filtration load of each bag.

[0004] Although the above solution addresses the issues of uneven airflow distribution and inconsistent bag wear in traditional equipment to some extent through the linkage of differential pressure feedback and airflow distribution, the baffle plate in this solution is a single rigid plate arranged in parallel. During operation, it is in direct contact with the dust-laden airflow. When the baffle plate is tilted and adjusted by the wire control, the airflow velocity on the plate surface decreases, forming a local vortex zone. Dust adheres to the plate surface and edges in large quantities due to inertial collisions and vortex retention. Furthermore, the parallel arrangement of the plates easily forms a "slit effect," further aggravating dust deposition. In addition, the baffle plate has no self-cleaning structure, and the adhered dust gradually thickens, causing the actual flow area of ​​the flow control box to deviate from the design value, thus compromising the accuracy of airflow distribution. Summary of the Invention

[0005] To address the aforementioned issues, a high-efficiency cyclone bag filter is provided. By incorporating a baffle plate, a first rotating shaft, an angle control structure, and a vibration self-cleaning structure, it achieves dynamic airflow distribution while simultaneously cleaning the baffle plate, preventing dust accumulation that could cause the actual flow area of ​​the air inlet channel to deviate from the adjustment target.

[0006] To address the problems of existing technologies, this invention provides a high-efficiency cyclone baghouse dust collector, comprising a dust collector bag, a differential pressure feedback component, and an airflow distribution structure. The airflow distribution structure includes a flow control box, a baffle plate, a first rotating shaft, an angle control structure, and a vibration self-cleaning structure. The baffle plate comprises two parallel plates. The first rotating shaft is hollow and located at both ends of the baffle plate. The angle control structure includes a transmission plate and a transmission arm. The transmission plate is connected to the differential pressure feedback component, and the transmission arm connects the transmission plate to the first rotating shaft. The vibration self-cleaning structure includes a connecting frame, a second rotating shaft, a vibration generating component, and a linkage drive structure. The connecting frame is parallel to the two plates and connected to the first rotating shaft. The second rotating shaft passes through the hollow first rotating shaft. The vibration generating component is located on the second rotating shaft. The linkage drive structure connects the first rotating shaft and the second rotating shaft.

[0007] Preferably, the linkage drive structure includes a third rotating shaft, a friction plate, and a friction wheel; the third rotating shaft is parallel to the second rotating shaft and the two are connected in a transmission manner; the friction plate is disposed on the lower surface of the transmission plate and abuts against the friction wheel; the friction wheel is disposed on the third rotating shaft.

[0008] Preferably, the end of the third rotating shaft is provided with a rotation amplification component, which is used to amplify the rotational speed of the third rotating shaft and increase the rotational speed of the second rotating shaft.

[0009] Preferably, the vibration generating assembly includes multiple vibration generating columns, which are arranged in a spiral shape on the second rotating shaft. The rotation of the second rotating shaft causes the vibration generating columns to contact the plate, thereby pushing the plate to move and achieve vibration.

[0010] Preferably, the vibration generating assembly further includes a plurality of rollers, which are respectively disposed at the ends of the plurality of vibration generating columns, and the rollers are in contact with the plate.

[0011] Preferably, the vibration self-cleaning structure further includes two vibration limiting components, which are respectively disposed on both sides of the connecting frame and respectively connected to the two plates. The vibration limiting components are used to connect the plates and the connecting frame.

[0012] Preferably, the wind deflector further includes multiple reset components, which provide a force to bring the two plates closer together.

[0013] Preferably, the wind deflector further includes an annular cover made of a flexible material, which surrounds the edges of the two plates and seals the space between the two plates.

[0014] Preferably, the angle control structure further includes two guide structures, which are respectively disposed at both ends of the transmission plate, and the guide structures are used to control the movement of the transmission plate on a fixed horizontal plane.

[0015] Preferably, the angle control structure further includes a buffer reset member, which compresses and stores energy when the transmission plate moves and provides thrust when the transmission plate resets.

[0016] The advantages of this invention application compared to the prior art are:

[0017] 1. This invention application includes a baffle plate, a first rotating shaft, an angle control structure, and a vibration self-cleaning structure. During rotation, the first rotating shaft drives a second rotating shaft passing through it to rotate synchronously via a linkage drive structure. When the second rotating shaft rotates, it drives a vibration generating component on it to contact the two plates of the baffle plate, thereby causing the two plates to vibrate and shake off the dust adhering to the surface of the plates. The shaken-off dust enters the subsequent dust collector bag area with the airflow and is filtered and collected. Through the linkage design of the vibration self-cleaning structure and the angle control structure in the above working process, the airflow is dynamically distributed while the baffle plate is self-cleaned, avoiding dust accumulation that causes the actual flow area of ​​the air inlet channel to deviate from the adjustment target.

[0018] 2. This invention application sets up a third rotating shaft, a friction plate, and a friction wheel. When the transmission plate moves horizontally, it drives the friction plate on the lower surface to move horizontally in the same direction. The friction force generated between the friction plate and the friction wheel drives the friction wheel to rotate, which in turn drives the third rotating shaft, which is fixed to the friction wheel, to rotate synchronously. When the third rotating shaft rotates, it smoothly transmits power to the second rotating shaft, causing the second rotating shaft to rotate as well. After the second rotating shaft rotates, it drives the vibration generating component to contact the baffle plate, causing the plate to vibrate to achieve self-cleaning. Through the design of the above-mentioned linkage drive structure, the efficient linkage between the vibration self-cleaning structure and the angle adjustment structure is realized.

[0019] 3. This invention application provides a rotary amplification component. According to the transmission ratio principle, the rotary amplification component causes the second rotating shaft to rotate at a higher speed than the third rotating shaft. After the second rotating shaft rotates at high speed, it will drive the vibration generating component on it to move quickly and continuously contact the plate body of the windshield, causing the plate body to generate high-frequency vibration. The rotary amplification component effectively increases the rotation speed of the second rotating shaft, thereby significantly increasing the operating frequency of the vibration generating component.

Detailed Implementation

[0032] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 11 As shown: A high-efficiency cyclone bag filter dust collector includes a dust collector bag 1, a differential pressure feedback component 2, and an airflow distribution structure. The airflow distribution structure includes a flow control box 3, a baffle plate 4, a first rotating shaft 5, an angle control structure 6, and a vibration self-cleaning structure 7. The baffle plate 4 includes two parallel plates 41. The first rotating shaft 5 is a hollow structure and is located at both ends of the baffle plate 4. The angle control structure 6 includes a transmission plate 61 and a transmission arm 62. The transmission plate 61 is connected to the differential pressure feedback component 2, and the transmission arm 62 is connected to... The transmission plate 61 is connected to the first rotating shaft 5, and the transmission arm 62 is a telescopic arm; the vibration self-cleaning structure 7 includes a connecting frame 71, a second rotating shaft 72, a vibration generating component 73, and a linkage drive structure 74. The connecting frame 71 is arranged parallel between the two plates 41 and connected to the first rotating shaft 5. The second rotating shaft 72 passes through the hollow first rotating shaft 5. The vibration generating component 73 is arranged on the second rotating shaft 72. The linkage drive structure 74 connects the first rotating shaft 5 and the second rotating shaft 72.

[0034] After the equipment starts, dusty air first enters the flow control box 3 of the air volume distribution structure and flows to the dust collector bag 1 through the maximum air intake channel formed by adjacent vertical baffles 4. During this process, some dust will adhere to the surface of the baffles 4; as the equipment continues to operate, dust gradually accumulates on the inner wall of the dust collector bag 1, causing a change in the pressure difference between the inside and outside of the bag. At this time, the pressure difference feedback component 2 is triggered. The pressure difference feedback component 2 drives the transmission plate 61 connected to it to move horizontally. The transmission plate 61 drives the first rotating shaft 5 to rotate through the transmission arm 62. When the first rotating shaft 5 rotates, it will simultaneously drive the two plates 41 and the connecting frame 71 of the baffles 4 to rotate, so that the originally vertical baffles 4 gradually switch to an inclined state, and the air intake channel between adjacent baffles 4 is reduced accordingly, realizing dynamic adjustment of the air intake volume. Meanwhile, during the rotation of the first rotating shaft 5, the second rotating shaft 72, which passes through it, rotates synchronously through the linkage drive structure 74. When the second rotating shaft 72 rotates, it causes the vibration generating component 73 on it to contact the two plates 41 of the baffle plate 4, thereby causing the two plates 41 to vibrate and shake off the dust adhering to the surface of the plates 41. The shaken-off dust enters the subsequent dust collector bag 1 area with the airflow and is filtered and collected. Through the linkage design of the vibration self-cleaning structure 7 and the angle control structure 6 in the above working process, the dynamic distribution of airflow is achieved while the self-cleaning of the baffle plate 4 is completed, avoiding dust accumulation that causes the actual flow area of ​​the air inlet channel to deviate from the adjustment target.

[0035] Reference Figure 4 and Figure 5 As shown: The linkage drive structure 74 includes a third rotating shaft 741, a friction plate 742 and a friction wheel 743; the third rotating shaft 741 is parallel to the second rotating shaft 72 and the two are connected in a transmission manner; the friction plate 742 is disposed on the lower surface of the transmission plate 61 and abuts against the friction wheel 743; the friction wheel 743 is disposed on the third rotating shaft 741.

[0036] When dust adheres to the inner wall of the dust collector bag 1, the pressure difference between the inside and outside of the equipment changes. The pressure difference feedback component 2 is triggered and drives the transmission plate 61 to move horizontally (the direction of movement can be adjusted bidirectionally according to the pressure difference). When the transmission plate 61 moves horizontally, it drives the friction plate 742 on the lower surface to move horizontally in the same direction. Since the friction plate 742 and the friction wheel 743 on the third rotating shaft 741 are always in contact, the friction between them drives the friction wheel 743 to rotate, which in turn drives the third rotating shaft 741, which is fixed to the friction wheel 743, to rotate synchronously. When the third rotating shaft 741 rotates, it smoothly transmits power to the second rotating shaft 72, causing the second rotating shaft 72 to rotate as well. The second rotating shaft 72 is equipped with a vibration generating component 73. After the second rotating shaft 72 rotates, it drives the vibration generating component 73 to contact the plate 41 of the baffle plate 4, causing the plate 41 to vibrate to achieve self-cleaning. Through the design of the above-mentioned linkage drive structure 74, the efficient linkage between the vibration self-cleaning structure 7 and the angle adjustment structure is achieved.

[0037] Reference Figure 4 and Figure 6 As shown: A rotation amplification component 75 is provided at the end of the third rotating shaft 741. The rotation amplification component 75 is used to amplify the rotation speed of the third rotating shaft 741 and increase the rotation speed of the second rotating shaft 72.

[0038] Specifically, the rotary amplification assembly 75 includes a first drive wheel 751, a second drive wheel 752, and a synchronous belt 753. The first drive wheel 751 is connected to a third rotating shaft 741, and the second drive wheel 752 is connected to a second rotating shaft 72. The diameter of the first drive wheel 751 is larger than that of the second drive wheel 752. The synchronous belt 753 is sleeved on the outside of the first drive wheel 751 and the second drive wheel 752.

[0039] When dust adheres to the inner wall of the dust collector bag 1, causing a change in the pressure difference between the inside and outside of the equipment, the pressure difference feedback component 2 drives the transmission plate 61 to move horizontally. The friction plate 742 on the lower surface of the transmission plate 61 abuts against the friction wheel 743 on the third rotating shaft 741, causing the friction wheel 743 and the third rotating shaft 741 to rotate synchronously through friction. Since the first transmission wheel 751 is fixed to the end of the third rotating shaft 741, the rotation of the third rotating shaft 741 directly drives the first transmission wheel 751 to rotate synchronously. The rotational power of the first transmission wheel 751 is transmitted to the second transmission wheel 752 through the synchronous belt 753. According to the transmission ratio principle, since the diameter of the first transmission wheel 751 is larger than that of the second transmission wheel 752, the rotational speed of the second transmission wheel 752 is significantly amplified, thereby driving the second rotating shaft 72, which is fixedly connected to it, to rotate at a higher speed than the third rotating shaft 741. After the second rotating shaft 72 rotates at high speed, it will cause the vibration generating component 73 on it to act quickly and continuously contact the plate 41 of the baffle plate 4, causing the plate 41 to generate high-frequency vibration. The rotational amplification component 75 effectively increases the rotational speed of the second shaft 72, thereby significantly improving the operating frequency of the vibration generating component 73.

[0040] Reference Figure 4 and Figure 7 As shown: The vibration generating component 73 includes a plurality of vibration generating columns 731, which are arranged in a spiral shape on the second rotating shaft 72. The rotation of the second rotating shaft 72 drives the vibration generating columns 731 to contact the plate 41, thereby pushing the plate 41 to move and achieve vibration.

[0041] Since multiple vibration generating columns 731 are fixed spirally on the second rotating shaft 72, the high-speed rotation of the second rotating shaft 72 will drive these vibration generating columns 731 to rotate synchronously. During the rotation, the spirally arranged vibration generating columns 731 will periodically contact the two plates 41 of the baffle plate 4 and generate thrust, pushing the plates 41 to move. When the vibration generating column 731 disengages from the plate 41 as the shaft rotates, the plate 41 returns to its initial position, and then the next vibration generating column 731 continues to contact the plate 41 and push it to move. This cycle repeats, causing the plate 41 to form continuous high-frequency reciprocating vibration under the alternating action of thrust and restoring force. During this process, the plate 41 uses the inertia generated by the vibration to efficiently peel off the dust attached to its surface. The peeled dust follows the airflow into the subsequent dust collector bag 1 area to be filtered and collected. By arranging multiple vibration generating columns 731 in a spiral shape on the second rotating shaft 72, the multiple vibration generating columns 731 can contact the plate 41 in sequence and apply thrust during the rotation of the second rotating shaft 72, thereby achieving multiple driving vibrations of the plate 41, thus increasing the vibration frequency of the plate 41 per unit time and enhancing the continuity and efficiency of vibration cleaning.

[0042] Reference Figure 7As shown: The vibration generating assembly 73 further includes a plurality of rollers 732, which are respectively disposed at the ends of the plurality of vibration generating columns 731, and the rollers 732 are in contact with the plate 41.

[0043] The vibration generating column 731 is in direct contact with the plate 41, and sliding friction will occur between the two, causing wear on the plate 41 and the vibration generating column 731. Therefore, a roller 732 is provided at the end of each vibration generating column 731. When the second rotating shaft 72 drives the vibration generating column 731 to rotate, the roller 732 at the end of the vibration generating column 731 contacts and rolls with the plate 41. The roller 732 converts sliding friction into rolling friction. While pushing the plate 41 to move and generate vibration, it reduces frictional loss with the plate 41, thereby reducing the frictional resistance between the vibration generating component 73 and the plate 41, reducing component wear, and extending service life.

[0044] Reference Figure 4 and Figure 8 As shown: The vibration self-cleaning structure 7 also includes two vibration limiting components 76. The two vibration limiting components 76 are respectively disposed on both sides of the connecting frame 71 and are respectively connected to the two plates 41. The vibration limiting components 76 are used to connect the plates 41 and the connecting frame 71.

[0045] Specifically, the vibration limiting component 76 includes a sliding frame 761 and a limiting post 762. The sliding frame 761 is connected to the plate 41 and slides with the connecting frame 71. The sliding frame 761 has a sliding groove 7611. The limiting post 762 is fixedly connected to the connecting frame 71 and is located in the sliding groove 7611.

[0046] When the helically arranged vibration-generating column 731 on the second rotating shaft 72 periodically contacts the plate 41 and pushes it to move, the plate 41 begins to reciprocate to remove surface dust. During this process, the vibration of the plate 41 will drive the sliding frame 761 connected to it to move synchronously. Since the sliding frame 761 and the connecting frame 71 are in sliding fit, the sliding frame 761 will slide along the outer wall of the connecting frame 71 towards the side of the connecting frame 71; at the same time, the limiting column 762 fixed to the connecting frame 71 will move relative to the sliding frame 761 within the sliding groove 7611 of the sliding frame 761. When the plate 41 vibrates, it drives the sliding frame 761 to slide continuously until the limiting post 762 contacts the bottom of the groove 7611. At this point, the limiting post 762 forms a rigid block on the sliding frame 761, thereby restricting the plate 41 from moving further away from the connecting frame 71 and stopping the plate 41 from displacing in that direction. Subsequently, the plate 41 returns to its original position closer to the connecting frame 71, and the sliding frame 761 slides synchronously in the opposite direction with the plate 41. This cycle repeats, achieving stable vibration of the plate 41 within a limited amplitude. By setting vibration limiting components 76 on both sides of the connecting frame 71, the vibration amplitude of the plate 41 away from the connecting frame 71 can be limited, thereby effectively preventing the plate 41 from separating from the connecting frame 71 due to excessive vibration.

[0047] Reference Figure 4 and Figure 9 As shown: The wind deflector 4 also includes a plurality of reset components 42, which provide a force to bring the two plates 41 closer to each other.

[0048] Specifically, the reset assembly 42 includes two magnetic blocks 421 with opposite magnetic properties, which are respectively disposed on opposite sides of the two plates 41.

[0049] When the vibration generating column 731 on the second rotating shaft 72 rotates with the shaft, the roller 732 at its end periodically contacts the two plates 41 and applies a pushing force. When the pushing force acts on the plates 41, it is greater than the attraction force between the two magnetic blocks 421. The two plates 41 overcome the attraction force of the magnetic blocks 421 and separate from each other. At the same time, the sliding frame 761 connected to the plates 41 slides along the connecting frame 71, and the vibration limiting component 76 works synchronously to limit the separation amplitude. When the vibration generating column 731 rotates with the shaft and loses contact with the plates 41, the pushing force disappears. At this time, the attraction force between the two magnetic blocks 421 with opposite magnetic properties becomes dominant. Under the traction of this attraction force, the two plates 41 quickly move towards each other and return to their initial relative positions. Then, the next vibration generating column 731 continues to contact the plates 41 and push them to separate. The magnetic blocks 421 are then pulled back to their original positions. This cycle repeats, and together with the vibration generating component 73, the plates 41 achieve continuous reciprocating vibration. The reset assembly 42, which consists of magnetically opposite magnetic blocks 421, ensures that the plate 41 quickly returns to its initial position after the thrust of the vibration generating assembly 73 disappears.

[0050] Reference Figure 10 As shown: The wind deflector 4 also includes an annular cover 43, which is made of flexible material and is arranged around the edges of the two plates 41 to close the space between the two plates 41.

[0051] The annular cover 43 surrounds the edges of the two plates 41 and seals their internal space. When the dust-laden airflow passes through the baffle plate 4, the dust is blocked on the outside of the plates 41 and cannot enter the cavity between the two plates 41, thereby preventing the internal vibration generation component 73, reset component 42, etc. from being contaminated or blocked by dust.

[0052] Reference Figure 3 and Figure 11 As shown: The angle control structure 6 also includes two guide structures 63, which are respectively disposed at both ends of the transmission plate 61. The guide structures 63 are used to control the movement of the transmission plate 61 on a fixed horizontal plane.

[0053] Specifically, the guide structure 63 includes a guide rail 631 and a guide rod 632. The guide rod 632 is connected to the transmission plate 61 and is slidably disposed within the guide rail 631.

[0054] When the transmission plate 61 moves, it synchronously drives the guide rods 632 at both ends to slide smoothly along the extension direction of the guide rail 631. The guide rail 631 limits the movement trajectory of the guide rods 632 through its own structural limitation, preventing the guide rods 632 from shifting up and down or tilting left and right. This ensures that the transmission plate 61, which is fixedly connected to the guide rods 632, always moves smoothly horizontally within a fixed horizontal plane, without tilting, shifting, or moving up and down. Under the constraint of the guide structure 63, the transmission plate 61 moves smoothly, and the friction plate 742 on its lower surface can always maintain a stable contact with the friction wheel 743 on the third rotating shaft 741. This frictional force stably drives the friction wheel 743 and the third rotating shaft 741 to rotate, achieving stable power transmission.

[0055] Reference Figure 11 As shown: The angle control structure 6 also includes a buffer reset member 64, which compresses and stores energy when the transmission plate 61 moves and provides thrust when the transmission plate 61 resets.

[0056] The buffer reset component 64 is made of spring and is sleeved on the guide rod 632. When the transmission plate 61 moves, it will simultaneously squeeze the buffer reset component 64 sleeved on the guide rod 632, causing the buffer reset component 64 to undergo compression deformation. This converts the kinetic energy of the transmission plate 61 into elastic potential energy and stores it. As the dust accumulated in the dust collector bag 1 is cleaned or the equipment operating status is adjusted, the driving force of the differential pressure feedback component 2 gradually disappears. At this time, the buffer reset component 64, which stores elastic potential energy, begins to release energy and generates a reverse thrust acting on the transmission plate 61. Under the action of this thrust, the transmission plate 61 moves smoothly in the opposite direction of the original movement to reset, while simultaneously driving the guide rod 632 to slide in the opposite direction along the guide rail 631. The reverse thrust provided by the buffer reset component 64 during reset can push the transmission plate 61 to quickly return to the initial position without the need for an additional drive mechanism.

[0057] The above embodiments only illustrate one or more implementation methods of this invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention. Therefore, the protection scope of this invention should be determined by the appended claims.
