Description

Technical Field

[0001] This utility model belongs to the field of dust collector technology, specifically relating to a bag filter dust collector. Background Technology

[0002] In the field of industrial dust removal, baghouse dust collectors, with their highly efficient particulate matter capture capabilities, have become the core equipment for treating dust-laden gases. Depending on the differentiated needs of the application scenario, dust collectors can be divided into large multi-bag systems and small single-bag structures. Large baghouse dust collectors generally employ pulse-jet cleaning technology: compressed air is used to instantly impact the surface of the filter bags to remove dust. However, this technology requires an air compressor, air tank, and complex piping systems, increasing the equipment's footprint by 30%-50%, and the energy consumption for compressed air preparation accounts for more than 35% of the total operating cost. Furthermore, system maintenance requires regular inspections by professional personnel, further increasing operating costs and making it unsuitable for small-scale scenarios with limited space and budget.

[0003] Single-bag dust collectors are popular in laboratories and small workshops due to their compact structure and low purchase cost. However, existing single-bag equipment has significant drawbacks in the dust removal process:

[0004] The mainstream cleaning method is still manual disassembly—the machine needs to be stopped to remove the cloth bag, and the dust is removed by beating or rinsing, which takes 30-60 minutes per time, greatly reducing the utilization rate of the equipment;

[0005] The sealing structure is easily damaged: Frequent disassembly leads to aging and failure of the bag flange sealing ring, causing dust leakage and a decrease in filtration efficiency of more than 20%.

[0006] Safety hazard: Operators are directly exposed to high concentrations of dust, violating occupational health standards such as OSHA.

[0007] Although alternative solutions such as mechanical vibration exist, their vibration transmission efficiency is less than 40%, and rigid impacts can easily damage the fabric fibers and shorten the service life.

[0008] Therefore, there is an urgent need for a cleaning technology specifically designed for single-bag dust collectors, which can achieve efficient, low-energy, safe and reliable bag cleaning without disassembly, and meet the core needs of small venues. Utility Model Content

[0009] To address the above problems, the purpose of this utility model is to provide a bag filter that solves the problems of large footprint and high cost of traditional large bag filters with pulse jet cleaning, and low efficiency and inconvenient operation of traditional single-bag dust collectors which use disassembly to clean the filter bags.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: a bag filter, comprising a housing, a cover connected to the top of the housing by connecting bolts, an air outlet and an air inlet respectively opened at the top and bottom of the housing, a bag support clamped between the housing and the cover, a striking component rotatably mounted on the cover, the striking component comprising a rotating shaft, a portion of the rotating shaft located inside the bag support connected to multiple connecting rods, the ends of the connecting rods connected to striking balls, a vibration component installed on the inner wall of the bag support, the vibration component and the striking balls being installed at the same height, a dust collector bag fitted on the outer side of the bag support, the end of the dust collector bag clamped between the bag support and the cover.

[0011] The beneficial effects of this utility model are as follows: by rotating the entire striking component, the striking ball is swung and strikes the vibrating component, causing the vibrating component to vibrate, and the vibration is transmitted to the dust collector bag. The particles accumulated on the outside of the dust collector bag are conveniently removed by vibrating the dust collector bag.

[0012] In order to make the vibrating component vibrate effectively after being hit by the striking ball;

[0013] As a further improvement to the above technical solution: the vibration assembly includes a swing rod and an elastic paddle, the elastic paddle being a beryllium bronze sheet structure, the elastic paddle being fixedly installed at one end of the swing rod, and the other end of the swing rod being welded to the inner wall of the bag support.

[0014] The beneficial effects of this improvement are: the elastic lever has high fatigue strength and a large elastic modulus, enabling it to work under repeated bending and vibration for a long time; and the elastic lever will not generate sparks when struck, thus ensuring the safety of the dust collector.

[0015] In order to ensure that the vibration transmitted by the vibration assembly can evenly remove the particulate matter covering the surface of the dust collector bag;

[0016] As a further improvement to the above technical solution: the number of swing rods is multiple, and they are arranged in rows at equal intervals along the axial direction of the bag support, and the swing rods are evenly arranged in multiple rows around the axis of the bag support.

[0017] The beneficial effects of this improvement are: the swing rods, which are evenly distributed on the bag support, can transmit the vibration generated by the elastic lever when it is struck to the dust collector bag evenly, thereby ensuring the uniformity of cleaning the surface of the dust collector bag.

[0018] In order to effectively improve the striking effect of the ball;

[0019] As a further improvement to the above technical solution: the connecting rod is a rubber cylinder structure, and the striking ball is a rubber ball structure.

[0020] The beneficial effects of this improvement are as follows: the flexibility of the connecting rod allows the rotating shaft to swing the striking ball formed at the end of the connecting rod when it rotates, so that the striking ball has a higher rotational speed and strikes the elastic paddle, thereby realizing the effective vibration of the elastic paddle.

[0021] To effectively ensure the equipment's sealing performance;

[0022] As a further improvement to the above technical solution: the connection between the shell cover and the rotating shaft is formed with an annular groove adapted to install a dynamic sealing ring; the bag support includes an integrally formed hollow frame and a cover plate; the top of the cover plate is connected to the hollow frame; the hollow frame is clamped between the shell and the shell cover; and sealing rings are embedded on both the upper and lower end faces of the hollow frame; the end of the dust collector bag is clamped between the shell and the hollow frame; one end of the connecting bolt is rotatably connected to the shell through a pin; and the other end of the connecting bolt slides through a through groove opened on the shell cover and is threaded with a nut.

[0023] The beneficial effects of this improvement are: the use of sealing rings and dynamic sealing rings can effectively ensure the sealing performance of the device, thereby ensuring the dust removal and filtration effect of the device.

[0024] For easy rotation of the rotating shaft;

[0025] As a further improvement to the above technical solution: a handwheel is connected to the top of the rotating shaft.

[0026] The beneficial effect of this improvement is that the operator can hold the handwheel and rotate the shaft with less effort.

[0027] To visually determine whether the dust collector bags need cleaning;

[0028] As a further improvement to the above technical solution: a pressure gauge is installed on the top surface of the inner shell cover of the dust collector bag.

[0029] The beneficial effects of this improvement are: operators can observe the pressure inside the dust collector bag through a pressure gauge, and determine that the dust collector bag is blocked when the pressure exceeds the set threshold, thereby manually tapping the component to vibrate and clean the dust collector bag.

[0030] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0038] Example 1:

[0039] like Figure 1As shown in Figure 5: A baghouse dust collector includes a housing 1. A cover 2 is connected to the top of the housing 1 via connecting bolts 3. An air outlet 4 and an air inlet 5 are respectively opened at the top and bottom of the housing 1. A bag support 8 is clamped between the housing 1 and the cover 2. A striking component 7 is rotatably mounted on the cover 2. The striking component 7 includes a rotating shaft 71. Multiple connecting rods 73 are connected to the portion of the rotating shaft 71 located inside the bag support 8. A striking ball 74 is connected to the end of each connecting rod 73. A vibration component 9 is installed on the inner wall of the bag support 8 at the same height as the striking ball 74. A dust collector bag 10 is fitted onto the outer side of the bag support 8, with the end of the dust collector bag 10 clamped to the bag support. Between the 8 and the shell cover 2, the striking assembly 7 is rotated to cause the striking ball 74 to swing and strike the vibration assembly 9, causing the vibration assembly 9 to vibrate. The vibration is then transmitted to the dust collector bag 10, and the particles accumulated on the outside of the dust collector bag 10 are conveniently removed by vibrating the dust collector bag 10. The vibration assembly 9 includes a swing rod 91 and an elastic lever 92. The elastic lever 92 is a beryllium bronze sheet structure. The elastic lever 92 is fixedly installed at one end of the swing rod 91, and the other end of the swing rod 91 is welded to the inner wall of the bag support 8. The elastic lever 92 has high fatigue strength and a large elastic modulus, and can withstand repeated bending and vibration for a long time. Furthermore, the elastic lever 92 does not generate sparks when struck, thus ensuring the safety of the dust collector. The number of swing rods 91 is multiple, and they are arranged in rows at equal intervals along the axial direction of the bag support 8. The swing rods 91 are evenly arranged in multiple rows around the axis of the bag support 8. The swing rods 91, evenly distributed on the bag support 8, can uniformly transmit the vibration generated by the elastic paddle 92 when struck to the dust collector bag 10, thereby ensuring the uniformity of cleaning the surface of the dust collector bag 10. The connecting rod 73 is a rubber cylinder structure, and the striking ball 74 is a rubber ball structure. The flexibility of the connecting rod 73 allows the striking ball 74 formed at the end of the connecting rod 73 to swing when the rotating shaft 71 rotates, giving the striking ball 74 a higher rotational speed and causing it to strike the elastic paddle 92, achieving effective vibration of the elastic paddle 92. The shell cover 2 and the rotating shaft 92 are connected to the rotating shaft 92. The connecting joint of the rotating shaft 71 is formed with an annular groove adapted to install the dynamic sealing ring. The bag support 8 includes an integrally formed hollow frame 81 and a cover plate 82. The top of the cover plate 82 is connected to the hollow frame 81. The hollow frame 81 is clamped between the housing 1 and the cover 2, and sealing rings 11 are embedded on both the upper and lower end faces of the hollow frame 81. The end of the dust collector bag 10 is clamped between the housing 1 and the hollow frame 81. One end of the connecting bolt 3 is rotatably connected to the housing 1 via a pin, and the other end of the connecting bolt 3 slides through a through groove opened on the cover 2 and is threaded with a nut. The use of sealing rings 11 and dynamic sealing rings can effectively ensure the sealing of the device, thereby ensuring the dust removal and filtration effect of the device. A handwheel 72 is connected to the top of the rotating shaft 71.The operator can easily rotate the rotating shaft 71 by holding the handwheel 72. A pressure gauge 6 is installed on the top surface of the inner cover 2 of the dust collector bag 10. The operator can observe the pressure inside the dust collector bag 10 through the pressure gauge 6. When the pressure exceeds a set threshold, it is determined that the dust collector bag 10 is blocked, and the operator can then manually tap the component 7 to vibrate and clean the dust collector bag 10.

[0040] The working principle of this technical solution is as follows: Dust-laden gas enters the interior of the housing 1 through the air inlet 5. Through the filtration effect of the dust collector bag 10, the dust is intercepted on the outside of the dust collector bag 10, while clean air is discharged through the air outlet 4. During equipment operation, the operator can observe the pressure gauge 6 installed on the top surface of the inner cover 2 of the dust collector bag 10 in real time. When the pressure value displayed by the pressure gauge 6 exceeds the preset threshold, it indicates that too much dust has accumulated on the surface of the dust collector bag 10, causing blockage and requiring cleaning. At this time, the operator holds the handwheel 72 at the top of the rotating shaft 71 and rotates the handwheel 72 clockwise or counterclockwise to rotate the rotating shaft 71. The rotating shaft 71, located inside the bag support 8, is connected to multiple connecting rods 73, which rotate accordingly. Since the connecting rods 73 are rubber cylinders, they are flexible and swing the striking balls 74 at their ends during rotation. This causes the striking balls 74 to swing at a high speed and strike the vibration component 9. The beryllium bronze sheet structure of the elastic paddle 92 vibrates after being struck by the striking balls 74. With its high fatigue strength and large elastic modulus, the elastic paddle 92 can stably and evenly transmit the vibration to the dust collector bag 10 through the swinging rod 91, causing the dust collector bag 10 to vibrate at high frequency. The particles attached to the outside of the dust collector bag 10 fall off under the action of vibration, achieving the purpose of dust removal.
