Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology for hot-dip galvanizing production, specifically to a zinc fume dust removal device for hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing is a common metal corrosion protection process. During the immersion of workpieces in molten zinc, a large amount of zinc fumes containing zinc vapor, zinc oxide dust, and other harmful impurities are generated. If these zinc fumes are directly released into the air, they will not only cause serious pollution to the surrounding environment but also harm the health of operators. Furthermore, zinc is a valuable metal resource, and direct emission of these fumes also represents a waste. Currently, most existing hot-dip galvanizing fume dust removal devices use filter bag dust collection methods.

[0003] However, existing filter bag dust collection devices have the following shortcomings:

[0004] (1) Dust in zinc fume is easily adhered to the surface of filter bags due to factors such as electrostatic adsorption and mechanical adhesion. Conventional dust removal methods are difficult to completely remove dust, which leads to easy clogging of filter bags and increased filtration resistance. Frequent replacement of filter bags is required, which not only increases equipment maintenance costs but also affects production efficiency due to downtime maintenance.

[0005] (2) After the dust in the zinc fume is blown out of the filter bag through the back-blowing pipe, it is easy to stick to the inner wall of the dust collector and is difficult to remove quickly;

[0006] (3) After filtering the dust in the zinc fume, the filter bag will trap the combustible zinc oxide dust. The filter bag will accumulate static electricity due to friction and induction during filtration. If the voltage exceeds the threshold, it will release sparks, which may easily cause dust explosion or ignite volatile organic compounds, posing a safety hazard.

[0007] To address this issue, we propose a hot-dip galvanizing fume dust removal device. Summary of the Invention

[0018] Beneficial effects

[0019] This invention provides a hot-dip galvanizing fume dust removal device. Compared with the prior art, it has the following advantages:

[0020] (1) By setting up the bag-shaking mechanism, in conjunction with the blower and the back-blowing pipe, compressed air is blown into the filter bag through the back-blowing pipe, causing the surface of the filter bag to bulge violently. At the same time, the airflow impact breaks the adhesion between the dust layer and the surface of the filter bag, causing the dust to peel off from the filter bag. The intermittent force of the U-shaped beater impacts the filter bag, causing the filter bag to vibrate, breaking the electrostatic adsorption and mechanical adhesion of the dust, accelerating the complete peeling of the dust, reducing the filter bag clogging rate and filtration resistance, reducing the frequency of filter bag replacement, reducing maintenance costs and ensuring production efficiency.

[0021] (2) By setting up the swing dust removal component and linking it with the power-saving bag shaking mechanism, when the U-shaped paddle moves, it synchronously drives the knocking ball on the swing dust removal component to quickly knock the box wall, knocking off the dust adhering to the box wall, avoiding the back-blown dust from sticking to the box wall, realizing the rapid dust removal and collection, and improving the convenience of cleaning the dust removal box.

[0033] 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.

[0034] The present invention provides three technical solutions, specifically including the following embodiments:

[0035] Example 1

[0036] Please see Figures 1-5A hot-dip galvanizing zinc fume dust removal device includes a dust collection box 1, which serves as the core processing chamber. The dust collection box 1 is welded from Q235 steel plate, and its inner wall is coated with a high-temperature resistant anti-corrosion coating to effectively resist the corrosion and erosion of hot-dip galvanizing zinc fumes. A square box 9 is connected to one side of the dust collection box 1. The square box 9 has a rectangular cavity structure and is equipped with a honeycomb-shaped flow guide grid inside, which can initially rectify the incoming zinc fumes and prevent turbulent airflow from impacting the filter bags 3. An inlet pipe 10 is connected to one side of the square box 9. The inlet pipe 10 is a DN300 seamless steel pipe and is connected to the external hot-dip galvanizing zinc pot's fume collection hood via a flange. A high-temperature resistant asbestos sealing gasket is installed at the connection to ensure no zinc fume leakage. Under the negative pressure of the induced draft fan, the external hot-dip galvanizing zinc fumes are drawn through... After the flue gas enters the square box 9 through the inlet pipe 10 and is rectified, it then enters the dust collector 1 evenly for dust removal. The other side of the dust collector 1 is connected to the outlet box 11, and the bottom of the outlet box 11 is connected to the outlet pipe 12. The filtered flue gas enters the outlet box 11 and the outlet pipe 12, and then is discharged to the outside through the outlet pipe 12. The bottom of the dust collector 1 has an inverted conical structure with a cone angle of 60° to facilitate dust collection. A dust collector pipe 13 is connected to the center of the bottom, and the bottom of the dust collector pipe 13 is connected to a collection box 14 via a flange. The collection box 14 is made of stainless steel and is used to collect the filtered dust. A rotating door 15 is connected to one side of the collection box 14 via a hinge. The door is equipped with a stainless steel door lock and a EPDM rubber sealing gasket. The sealing gasket effectively prevents dust leakage and avoids secondary pollution. The top of the dust collector 1 is hinged to a cover 16, the size of which matches the opening at the top of the dust collector 1. It features a double-layer steel plate structure. After opening the cover 16, the filter bags 3 can be directly removed for replacement and maintenance. The cover 16 also has a door lock and sealing gasket on its edge to ensure the airtightness of the dust collector 1. A baffle 2, made of stainless steel, is horizontally fixed to the inner wall of the dust collector 1 and welded to the body. Multiple filter bags 3, made of polytetrafluoroethylene, are connected to its bottom via clamps. The top of the filter bags 3 is sealed to the baffle 2 via clamps, while the bottom is suspended, for efficient filtration of zinc oxide dust and other fine particles in hot-dip galvanizing fumes. To remove impurities, a blower 4 is installed on one side of the dust collector 1. The blower 4 is controlled by an external PLC control cabinet switch and is electrically connected to a 380V external power supply. Multiple back-blowing pipes 5 are connected to the air outlet of the blower 4. Each back-blowing pipe 5 corresponds to a set of filter bags 3. Multiple air outlets are evenly opened at the bottom of the back-blowing pipe 5 along the length direction. The air outlets face the central axis of the filter bags 3. When the blower 4 is started, compressed air is blown into the back-blowing pipe 5 and then sprayed into the filter bags 3 through the air outlets at a flow rate of 15-20m / s. This causes the filter bags 3 to expand instantly from their natural state. The surface of the filter bags 3 undergoes violent swelling and deformation. At the same time, the impact of the high-speed airflow breaks the mechanical adhesion between the dust layer and the surface of the filter bags 3, thus initially achieving dust removal.The detached dust falls off the surface of the filter bag 3 under the action of gravity and is collected in the collection box 14 below. One end of the back-blowing pipe 5 extends into the interior of the dust collection box 1, and the air outlet of the back-blowing pipe 5 is located directly above the filter bag 3. The dust collection box 1 is equipped with a power-saving shaking mechanism 6 to accelerate the removal of dust from the filter bag 3.

[0037] The power-accumulating bag-shaking mechanism 6 includes two horizontal plates 61 installed inside the dust collector 1. Two horizontal bars 62 are fixed between the opposite sides of the two horizontal plates 61. Three U-shaped beaters 63 are fixed on the two horizontal bars 62. The U-shaped beaters 63 are used to beat the filter bag 3, causing the filter bag 3 to shake and accelerate the discharge of dust. A drive assembly 64 is installed on one side of the dust collector 1. The drive assembly 64 is used to drive the U-shaped beaters 63 to accumulate power and use elastic force to impact the filter bag 3, causing the filter bag 3 to vibrate, thereby accelerating the discharge of dust inside the filter bag 3.

[0038] The drive assembly 64 includes a fixed plate 641 fixed to one side of the dust collection box 1. Two L-shaped seats 642 are fixed to the top of the fixed plate 641. Limiting rods 643 are fixed between the opposite sides of the two L-shaped seats 642. A slide block 644 is slidably connected between the outer surfaces of the two limiting rods 643. A motor 645 is fixed to one side of the fixed plate 642. The motor 645 is controlled by an external switch and electrically connected to an external power supply. A rotating wheel 646 is fixed to the output end of the motor 645. A Z-shaped arc groove 647 is opened on the rotating wheel 646. When a protrusion 648 is fixed to the bottom of the slide block 644, the Z-shaped arc groove 647 is divided into an arc groove part and a horizontal groove part. When the protrusion 648 slides to the horizontal groove part, the spring 649 returns to its original position, and the elastic force drives the slide block 644 to move quickly to the right.

[0039] The bottom of the protruding post 648 extends into the interior of the Z-shaped arc groove 647, and the protruding post 648 slides in the Z-shaped arc groove 647. A spring 649 is sleeved on the limiting rod 643. The spring 649 is used to charge and eject the slide 644, so that the U-shaped beater 63 can beat the filter bag 3, causing the filter bag 3 to shake. One end of the spring 649 is fixed to one side of the L-shaped seat 642, and the other end of the spring 649 is fixed to one side of the slide 644. Two connecting rods 6410 are fixed to one side of the slide 644, and one end of the two connecting rods 6410 is fixed to one side of the horizontal plate 61.

[0040] By setting up the bag-shaking mechanism 6, in conjunction with the blower 4 and the back-blowing pipe 5, compressed air is blown into the filter bag 3 through the back-blowing pipe 5, causing the surface of the filter bag 3 to bulge violently. At the same time, the airflow impact breaks the adhesion between the dust layer and the surface of the filter bag 3, causing the dust to peel off from the filter bag 3. The intermittent force-accumulating impact of the U-shaped beater 63 on the filter bag 3 causes the filter bag 3 to vibrate, breaking the electrostatic adsorption and mechanical adhesion of the dust, accelerating the complete peeling of the dust, reducing the clogging rate and filtration resistance of the filter bag 3, reducing the replacement frequency of the filter bag 3, reducing maintenance costs and ensuring production efficiency.

[0041] Example 2

[0042] Based on Example 1, see Figures 6-7 As shown, two swing-type dust-removing assemblies 7 are provided between one side of the U-shaped beater 63 and the inner wall of the dust collection box 1. The swing-type dust-removing assembly 7 includes a square plate 71 fixed to one side of the dust collection box 1, a support plate 72 fixed to one side of the square plate 71, a slide rail 73 fixed to the top of the support plate 72, a movable plate 74 provided above the support plate 72, a movable seat 75 fixed to the bottom of the movable plate 74, the movable seat 75 slides on the slide rail 73, and a curved groove 76 is provided through the top of the movable plate 74. A side plate 77 is fixed to one side of the U-shaped beater 63, and a side rod 78 is fixed to one side of the side plate 77.

[0043] A mounting plate 79 is fixed to one end of the side rod 78. The bottom of the mounting plate 79 is fixed to the top of the movable plate 74. The top of the support plate 72 is rotatably connected to the swing plate 710 via a pivot. A fixing post 711 is fixed to the top of the swing plate 710. The top of the fixing post 711 extends into the inside of the curved groove 76. The size of the fixing post 711 matches that of the curved groove 76, and the fixing post 711 slides inside the curved groove 76. When the fixing post 711 slides in the curved groove 76, it can drive the swing plate 710 to swing around the pivot. A mounting base 712 is fixed on the swing plate 710. A swing rod 713 is fixed to one side of the mounting base 712. A knocking ball 714 is fixed to one end of the swing rod 713. One side of the knocking ball 714 intermittently contacts and presses against the inner wall of the dust collection box 1. The knocking ball 714 is set to knock on the box wall to shake off the dust adhering to the box wall.

[0044] By setting up the swing dust removal component 7 and linking it with the power-saving bag shaking mechanism 6, when the U-shaped beater 63 moves, it synchronously drives the knocking ball 714 on the swing dust removal component 7 to quickly knock off the dust adhering to the box wall, avoiding back-blown dust from sticking to the box wall, realizing the rapid falling and collection of dust, and improving the ease of cleaning the dust collector box 1.

[0045] Example 3

[0046] Based on Example 2, see Figures 8-9 As shown, an electrostatic discharge assembly 8 is provided between the three U-shaped beaters 63 and the inner wall of the dust collection box 1. The electrostatic discharge assembly 8 includes a support plate 81 fixed on one side of the three U-shaped beaters 63, a rack 82 fixed between one side of the three support plates 81, and a gear 84 rotatably connected to one side of the inner wall of the dust collection box 1 through a rotating rod 83. The gear 84 meshes with the rack 82, and a circular plate 85 is fixed to one side of the gear 84.

[0047] A mounting column 86 is fixed on one side of the circular plate 85. A wing plate 87 is rotatably connected to one side of the inner wall of the dust collector 1 via a drive rod 89. A groove 88 is provided on the wing plate 87. The mounting column 86 slides in the groove 88. The size of the mounting column 86 and the groove 88 are matched. Multiple conductive rods 810 are fixed on the drive rod 89. A conductive ball 811 is fixed on the conductive rod 810. One side of the conductive ball 811 intermittently contacts and presses against the surface of the filter bag 3. Both the conductive rod 810 and the conductive ball 811 are made of conductive metal material and are grounded through a wire, which can quickly remove static electricity from the filter bag 3.

[0048] By setting up the electrostatic discharge component 8 and linking it with the energy-saving bag shaking mechanism 6, the conductive ball 811 intermittently contacts the filter bag 3 to conduct away the static electricity generated by friction and induction on the surface of the filter bag 3 in real time, avoiding the release of sparks due to voltage exceeding the threshold and eliminating the safety hazards of dust explosion and ignition of volatile organic compounds.

[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0050] During operation, hot-dip galvanized zinc fumes are introduced into the square box 9 through the inlet pipe 10, then into the dust collector 1, and finally into the filter bag 3. The filter bag 3 filters the dust in the zinc fumes. The filtered zinc fumes enter the outlet box 11 and are discharged through the outlet pipe 12. The blower 4 is started, and the blower 4 blows air into the filter bag 3 through the back-blowing pipe 5. Compressed air is rapidly introduced into the filter bag 3 through the back-blowing pipe 5. The airflow forms a high-speed jet through the air outlet on the back-blowing pipe 5, which instantly rushes into the interior of the filter bag 3. The high-speed back-blowing airflow causes the filter bag 3 to switch to an internal blowing expansion state, and the surface of the filter bag 3... A violent expansion occurs, and the airflow impact breaks the adhesion between the dust layer and the surface of the filter bag 3. The detached dust falls off the surface of the filter bag 3 under gravity and is collected in the collection box 14 below, restoring the filtration capacity of the filter bag 3. During this process, the motor 645 is started, which drives the rotating wheel 646 to rotate, thereby causing the protrusion 648 to slide in the Z-shaped arc groove 647, which in turn causes the slide block 644 to slide from right to left, thereby squeezing and compressing the two springs 649. When the protrusion 648 slides to the transverse groove part of the Z-shaped arc groove 647, the elastic force of the spring 649 pushes the slide block 644 to move. The seat 644 moves rapidly to the left, which in turn moves the U-shaped paddle 63. The U-shaped paddle 63 impacts one side of the filter bag 3, causing the filter bag 3 to shake, thereby accelerating the discharge of dust from the expanded filter bag 3. When the dust is discharged into the dust collector 1, some dust adheres to the box wall. As the U-shaped paddle 63 moves, it simultaneously moves the moving plate 74, which in turn causes the fixed column 711 to slide in the curved groove 76. The curved groove 76 then causes the swing plate 710 to swing around the rotating axis, which in turn causes the striking ball 714 to swing. The striking ball 714 intermittently strikes the box wall, thereby utilizing... The dust adhering to the box wall is vibrated by the tapping ball 714, causing the dust to fall off quickly and completing the dust cleaning. When the U-shaped beater 63 moves, it drives the rack 82 to move synchronously. The rack 82 then drives the two gears 84 to rotate. The gears 84 drive the circular plate 85 and the mounting column 86 to rotate. The mounting column 86 then drives the wing plate 87 to swing. The wing plate 87 then drives the drive rod 89, the conductive rod 810 and the conductive ball 811 to swing. The conductive ball 811 intermittently contacts and squeezes one side of the filter bag 3. The conductive ball 811 conducts away the static electricity on the filter bag 3, eliminating the risk of dust explosion.

[0051] The embodiments of the invention have been described in detail above, but the content described is only a preferred embodiment of the invention and should not be considered as limiting the scope of the invention. All equivalent changes and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
