Description

Technical Field

[0001] This invention relates to the field of bag filters, and more particularly to an airflow distribution device for bag filters that enhances dust separation efficiency. Background Technology

[0002] Baghouse dust collectors are highly efficient and environmentally friendly dust treatment equipment, widely used in industrial production processes to capture and separate particulate matter from the air. They use multiple fabric filter bags as the filter medium, introducing dust-laden gas into the equipment. The dust is trapped by the filter bags and accumulates on their surface, while the purified gas is discharged smoothly. Baghouse dust collectors have advantages such as large air volume handling capacity, high dust removal efficiency, stable operation, and convenient maintenance, making them suitable for various industries including power, metallurgy, chemical, and building materials. Furthermore, modern baghouse dust collectors are equipped with automatic cleaning systems that periodically remove accumulated dust from the filter bags, ensuring long-term efficient operation while reducing energy consumption and manual intervention.

[0003] In traditional dust removal equipment structures, when dust-laden gas enters the housing through the inlet duct, the lack of reasonable airflow organization and distribution measures easily leads to the formation of a highly concentrated, impactful airflow. This airflow often directly and continuously scours a fixed local area of ​​the filter bag, causing that area to bear an excessive filtration load. This not only accelerates filter material wear and shortens its service life, but also creates flow stagnation zones due to uneven airflow distribution within the housing. The gas renewal in these dead zones is slow, and dust easily accumulates, ultimately resulting in inconsistent filtration efficiency in different areas of the entire filtration system, significantly affecting the overall dust removal effect. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides an airflow uniform distribution device for baghouse dust collectors that enhances dust separation efficiency, aiming to improve the problem of uneven airflow distribution in existing baghouse dust collectors.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an airflow distribution device for a baghouse dust collector that enhances dust separation efficiency, comprising a housing and a pulse jet pipe, a flow-dividing assembly installed inside the housing, a connecting assembly installed inside the housing, a shaking mechanism installed inside the housing, and a collecting mechanism installed inside the housing; the flow-dividing assembly includes a flow-dividing plate, which is fixedly installed inside the housing; the shaking assembly includes a sliding frame, which is slidably connected inside the housing, and a filter bag is fixedly connected inside the sliding frame; a motor is fixedly connected to the outer wall of the housing, and a rotating disk is fixedly connected to the output end of the motor; a transmission rod is rotatably connected to the outer wall of the rotating disk; a push-pull rod is rotatably connected to one side of the transmission rod, and the push-pull rod is slidably connected inside the housing and fixedly connected to the top of the sliding frame.

[0006] Furthermore, the connecting assembly includes an air inlet pipe and an air outlet pipe, with the air inlet pipe fixedly connected to one side of the inside of the housing and the air outlet pipe fixedly connected to the other side of the inside of the housing.

[0007] Furthermore, the collection mechanism includes a support frame, which is fixedly connected to the bottom of the box.

[0008] Furthermore, the support frame is provided with a sliding groove, and a slider is slidably connected inside the sliding groove.

[0009] Furthermore, a bracket is fixedly connected to one side of the slider, and a threaded rod is rotatably connected inside the support frame.

[0010] Furthermore, the threaded rod is threadedly connected to the slider, and a bevel gear is fixedly connected to one end of the threaded rod.

[0011] Furthermore, a second bevel gear is rotatably connected inside the support frame, and the second bevel gear meshes with the first bevel gear.

[0012] Furthermore, a handle is fixedly connected to one end of the second bevel gear.

[0013] Furthermore, the collection mechanism also includes a dust collection box, the top of which is fixedly connected to a docking funnel.

[0014] Furthermore, a movable door panel is rotatably connected inside the dust collection box, and a handle is fixedly connected to the outer wall of the movable door panel.

[0015] The present invention has the following beneficial effects:

[0016] 1. In this invention, the airflow entering the chamber can be initially separated by the diverter plate. Then, the motor drives the rotating disk to rotate, which in turn drives one side of the transmission rod to move, thereby repeatedly pushing the push-pull rod. The push-pull rod drives the sliding frame to swing back and forth, which stirs the airflow around the filter bag on the sliding frame, so that the airflow passes through the filter bag evenly, improving the efficiency of dust separation.

[0017] 2. In this invention, the dust collection box is placed by a bracket, and the bevel gear two is controlled by a handle. At the same time, the bevel gear one drives the threaded rod to rotate, which causes the slider to move the bracket upward, so that the docking funnel at the top of the dust collection box fits against the bottom of the box, thus facilitating dust collection. The movable door panel can also be opened with the handle to clean the dust inside the dust collection box, improving the convenience of dust handling. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Figure 1 - Figure 4 An embodiment of the present invention provides an airflow distribution device for a bag filter dust collector that enhances dust separation efficiency, comprising a housing 1 and a pulse jet pipe 2, a flow distribution assembly installed inside the housing 1, a connecting assembly installed inside the housing 1, a shaking mechanism installed inside the housing 1, and a collection mechanism installed inside the housing 1; the flow distribution assembly includes a flow distribution plate 8, which is fixedly installed inside the housing 1; the shaking assembly includes a sliding frame 9, which is slidably connected inside the housing 1, and a filter bag 10 is fixedly connected inside the sliding frame 9; a motor 12 is fixedly connected to the outer wall of the housing 1, and a rotating disk 11 is fixedly connected to the output end of the motor 12; a transmission rod 14 is rotatably connected to the outer wall of the rotating disk 11; a push-pull rod 13 is rotatably connected to one side of the transmission rod 14; the push-pull rod 13 is slidably connected inside the housing 1; and the push-pull rod 13 is fixedly connected to the top of the sliding frame 9.

[0026] Specifically, the dust-laden gas first enters the housing 1 through the inlet pipe 3 in the connecting assembly. Upon entering the housing 1, the airflow first contacts the diversion plate 8 in the diversion assembly. The diversion plate 8 effectively breaks up the concentrated impact of the airflow, uniformly diverting and buffering the airflow, achieving initial uniform distribution. This avoids the problem of localized airflow concentration and accelerated filter bag wear caused by direct airflow impact on the filter bag 10, and also disperses the airflow in advance, laying a solid foundation for subsequent efficient dust separation and significantly reducing the risk of localized filter bag overload. After initial separation by the diversion plate 8, the airflow flows to the area where the shaking mechanism is located, activating the motor 12 fixedly connected to the outer wall of the housing 1. The output end of the motor 12 drives the rotating disk 11 to rotate synchronously. Since one end of the transmission rod 14 is rotatably connected to the outer wall of the rotating disk 11, the rotation of the rotating disk 11 drives one end of the transmission rod 14 to perform circular motion, thereby driving the transmission... The push-pull rod 13 is repeatedly pushed on the other side of rod 14. Since the push-pull rod 13 is slidably connected inside the housing 1 and fixedly connected to the top of the sliding frame 9, the reciprocating motion of the push-pull rod 13 causes the sliding frame 9 to swing back and forth smoothly inside the housing 1. The filter bag 10 fixedly connected inside the sliding frame 9 swings synchronously with the sliding frame 9. This can fully agitate the airflow around the filter bag 10, break the dead corner of airflow stagnation, and make the initially evenly distributed airflow further evenly distributed. This ensures that the airflow can pass through all areas of the filter bag 10 evenly and smoothly, effectively avoiding the problem of excessive local filtration load and uneven filtration effect of the filter bag 10, and greatly improving the dust separation efficiency. According to actual measurement, compared with the traditional device without shaking mechanism, the dust separation efficiency can be increased by 15%-25%. The filtered clean gas is discharged from the housing 1 through the exhaust pipe 4 in the connecting assembly. The dust content of the discharged gas can meet the industry emission standards.

[0027] During the dust separation process, the dust intercepted by the filter bag 10 falls steadily under gravity and enters the collection mechanism for centralized processing. In the collection mechanism, the dust collection box 6 receives the falling dust through the docking funnel 7 at the top. The docking funnel 7 can effectively expand the dust collection range and prevent dust from scattering outside the dust collection box 6. The dust collection box 6 is placed on the bracket 19, and one side of the bracket 19 is fixedly connected to the slider 18. The slider 18 is slidably connected inside the slide groove 17 opened in the support frame 5. The support frame 5 is fixedly connected to the bottom of the box 1. When it is necessary to adjust the height of the dust collection box 6 so that the docking funnel 7 fits against the bottom of the box 1 to improve the dust collection effect, the handle 23 at one end of the bevel gear 22 is turned. The operation is convenient and labor-saving, without the need for additional tools. The bevel gear 22 rotates smoothly inside the support frame 5. Since the bevel gear 22 meshes with the bevel gear 1 21, the transmission is smooth and without jamming. Wheel 22 drives bevel gear 21 to rotate synchronously, which in turn drives threaded rod 20, which is fixedly connected to bevel gear 21, to rotate inside support frame 5. Since threaded rod 20 is threadedly connected to slider 18, when threaded rod 20 rotates, it drives slider 18 to slide smoothly up and down along slide groove 17. Slider 18 drives bracket 19 and dust collection box 6 above to move synchronously, which can accurately achieve tight fit between docking funnel 7 and bottom of box 1. After fitting, dust leakage can be effectively reduced, allowing dust to fall smoothly and completely into dust collection box 6, improving dust collection rate. When dust accumulates to a certain amount in dust collection box 6, the movable door 15 connected to the inside of dust collection box 6 can be easily opened by pulling handle 16 on the outer wall of movable door 15, and the dust inside dust collection box 6 can be cleaned quickly without disassembling dust collection box 6, which effectively improves the convenience of dust handling and reduces the labor intensity of operators.

[0028] In addition, the pulse jet pipe 2, as an auxiliary component, can work in conjunction with the overall operation of the device to periodically and evenly blow dust onto the filter bag 10, promptly removing dust adhering to the surface of the filter bag 10, preventing the filter bag 10 from clogging, further ensuring the filtration efficiency and service life of the filter bag 10, extending the filter bag replacement cycle, reducing equipment operation and maintenance costs, and ensuring the long-term stable and efficient operation of the entire device.

[0029] Working principle: Dust-laden gas first enters the housing 1 through the inlet pipe 3 in the connecting assembly. Upon entering the housing 1, the airflow first contacts the diversion plate 8 in the diversion assembly. The diversion plate 8 performs preliminary diversion of the airflow, achieving initial uniform distribution. After preliminary separation by the diversion plate 8, the airflow flows towards the area where the shaking mechanism is located, activating the motor 12 fixedly connected to the outer wall of the housing 1. The output end of the motor 12 drives the rotating disk 11 to rotate synchronously. Since one end of the transmission rod 14 is rotatably connected to the outer wall of the rotating disk 11, the rotation of the rotating disk 11 drives one end of the transmission rod 14 to perform circular motion, thereby repeatedly pushing the push-pull rod 13 on the other side of the transmission rod 14. Rod 13 is slidably connected inside the housing 1 and fixedly connected to the top of the sliding frame 9. The reciprocating motion of the push-pull rod 13 causes the sliding frame 9 to swing back and forth inside the housing 1. The filter bag 10, which is fixedly connected inside the sliding frame 9, swings synchronously with the sliding frame 9. This agitates the airflow around the filter bag 10, further distributing the initially evenly distributed airflow and ensuring that the airflow can evenly pass through all areas of the filter bag 10, effectively avoiding the problem of excessive local filtration load on the filter bag 10. The filtered clean gas is discharged from the housing 1 through the exhaust pipe 4 in the connecting assembly. During the dust separation process, the dust intercepted by the filter bag 10 will fall under the action of gravity and enter the collection mechanism for collection. In the dust collection mechanism, the dust collection box 6 collects falling dust through the docking funnel 7 at the top. The dust collection box 6 is placed on the bracket 19, and one side of the bracket 19 is fixedly connected to the slider 18. The slider 18 is slidably connected inside the groove 17 opened in the support frame 5. When it is necessary to adjust the height of the dust collection box 6 so that the docking funnel 7 fits against the bottom of the box body 1 to improve the dust collection effect, the handle 23 at one end of the bevel gear 22 is turned. The bevel gear 22 rotates inside the support frame 5. Since the bevel gear 22 meshes with the bevel gear 21, the bevel gear 22 drives the bevel gear 21 to rotate synchronously, which in turn drives the threaded rod 20 fixedly connected to the bevel gear 21 to rotate in the support frame. The internal rotation of the frame 5 is achieved because the threaded rod 20 is threadedly connected to the slider 18. When the threaded rod 20 rotates, it drives the slider 18 to slide up and down along the slide groove 17. The slider 18 drives the bracket 19 and the dust collection box 6 above to move synchronously, so as to achieve a tight fit between the docking funnel 7 and the bottom of the box 1, which facilitates the smooth falling of dust into the dust collection box 6. When the dust in the dust collection box 6 accumulates to a certain amount, the movable door 15 connected to the inside of the dust collection box 6 can be opened by pulling the handle 16 on the outer wall of the movable door 15, so as to quickly clean the dust inside the dust collection box 6. In addition, the pulse jet pipe 2, as an auxiliary component, can cooperate with the overall operation of the device to periodically blow and clean the filter bag 10.
