Description

Technical Field

[0001] This invention relates to the field of dust collector filter bag technology, and more particularly to a high-efficiency dust removal filter bag. Background Technology

[0002] Dust collector filter bags are considered the heart of baghouse dust collectors, and are generally referred to as filter bags, dust collection bags, dust bags, dust collection bags, dust collector bags, dust collector bags, etc. Dust collector filter bags are a crucial component in the operation of baghouse dust collectors; typically, cylindrical filter bags are suspended vertically inside the dust collector. A dust collector or dust removal equipment is a device that separates dust from flue gas. Baghouse dust collectors, also known as filtration dust collectors, are a type of dry, high-efficiency dust collector. They utilize bag-type filter elements made of woven fiber fabric to capture solid particles in dust-laden gas. Their working principle is that dust particles are intercepted by colliding with the filter fibers due to inertial forces as they wrap around them. In pulse-jet and box-type pulse-jet dust collectors, dust adheres to the outer surface of the filter bag. When dust-laden gas passes through the dust collector, the dust is captured on the outer surface of the filter bag, while clean gas passes through the filter media and enters the interior of the filter bag. The cage inside the filter bag supports the filter bag and prevents it from collapsing. It also helps to remove and redistribute the dust cake. In industrial applications, multiple filter cartridges are installed inside the filter bag unit for large-area filtration.

[0003] Most existing filter bag devices with multiple filter cartridges are bulky. In order to achieve effective dust removal efficiency, the filter bag device is often required to operate almost 24 hours a day. Therefore, it is especially important to detect faults in a timely manner and replace them quickly.

[0004] However, with current filter bag systems, if a filter cartridge malfunctions and displays abnormal data, the system needs to be shut down to stop emissions and replace the cartridge. This shutdown means a decrease in effective dust removal efficiency, and if the replacement cannot be completed accurately and quickly, the downtime will be even longer. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a high-efficiency dust removal filter bag that can simultaneously detect multiple filter cartridges, automatically replace filter cartridges in a timely manner, has a high degree of automation, reduces downtime, and thus improves the actual effective dust removal efficiency of the filter bag.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency dust removal filter bag, comprising a filter bag mounting plate and a sealing side plate. The sealing side plate is welded to one side of the top of the filter bag mounting plate. A drive management plate is welded to one side of the mounting plate. Limit plates are welded to both sides of the top of the drive management plate. A drive platform is slidably mounted on the top of the drive management plate near the limit plates. A pneumatic bag-lifting and pushing mechanism is detachably mounted on the top of the drive platform via bolts. A stepper motor is fixedly mounted on one side of the limit plates via bolts. The output end of the stepper motor is fixedly mounted via a coupling.

A controller is detachably installed on one side of the drive management plate.

[0007] Furthermore, the pneumatic bag-taking and pushing mechanism includes a cylinder, a pushing block, an electric push rod, a top plate, a stepper motor, and a filter bag torsion assembly.

The two sets of second electromagnetic push rods are fixedly installed at both ends away from the dust collector filter bag by bolts. Clamping blocks are fixedly installed at the output ends of the two sets of first electromagnetic push rods and the two sets of second electromagnetic push rods by bolts.

[0009] Furthermore, the filter bag installation mechanism includes four sets of mounting blocks, two sets of bidirectional lead screws, two sets of stepper motors, a synchronization block, two sets of clamping blocks, a pressure ring, and a locking ring. The four sets of mounting blocks are distributed and welded to the top of the mounting plate and located at the four corners of the through hole. The two sets of bidirectional lead screws are rotatably installed inside the mounting blocks. The two sets of stepper motors are respectively installed on the mounting blocks on the side away from the sealing side plate. The output ends of the two sets of stepper motors are fixedly installed with the two sets of bidirectional lead screws. Synchronization blocks are welded to both sides of the two sets of clamping blocks. The synchronization blocks are threadedly connected to the bidirectional lead screws. The pressure ring is sleeved on the bottom surface of the dust collector filter bag. The locking ring is sleeved on the top surface of the dust collector filter bag. The surface of the locking ring has a groove for clamping and engaging with the locking block.

[0010] Furthermore, the gate sealing assembly includes a second cylinder, a connecting rod, a sealing plate, and a sealing ring. The second cylinder is fixedly installed on the side of the sealing side plate near the replacement port by bolts. The connecting rod is welded to the piston end of the second cylinder. The sealing plate is slidably installed on the replacement port side. The sealing plate is welded and fixed to the end of the connecting rod away from the second cylinder.

[0013] Furthermore, a limit block is welded to the top of one side of the electric push rod, and a slide rod is slidably installed inside the limit block. One end of the slide rod is welded and fixed to the top plate. A stabilizing frame is welded to the top of the push block, and the top of the stabilizing frame is rotatably connected to the second output end of the stepper motor.

[0014] The beneficial effects of this invention are as follows: This invention uses a gas-sensitive sensor for data monitoring, and a controller, in conjunction with a pneumatic bag-picking and pushing mechanism, pushes the spare dust collector filter bag and the gate sealing assembly into the mounting plate. Subsequently, the damaged dust collector filter bag and the filter bag to be replaced are automatically replaced by twisting their positions. This improves the stability of the dust collector filter bag in flue gas filtration, and the overall equipment has a high degree of automation, reducing downtime due to malfunctions, thereby improving the actual effective dust removal efficiency of the filter bag.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the present invention.

[0025] A high-efficiency dust removal filter bag includes a filter bag mounting plate 1 and a sealing side plate 2. The sealing side plate 2 is welded to one side of the top of the filter bag mounting plate 1. A drive management plate 3 is welded to one side of the mounting plate 1. Limiting plates 4 are welded to both sides of the top of the drive management plate 3. A drive platform 5 is slidably mounted on the top of the drive management plate 3 near the limiting plates 4. A pneumatic bag-lifting and pushing mechanism 6 is detachably mounted on the top of the drive platform 5 by bolts. A stepper motor 7 is fixedly mounted on one side of the limiting plates 4 by bolts.

The drive platform 5 and the limit plate 4 are rotatably installed. The screw 8 is threadedly connected to the drive platform 5. The top of the mounting plate 1 has a through hole 9. The top of the mounting plate 1 is fixedly installed with a filter bag mounting mechanism 10 located at the top of the through hole 9. The sealing side plate 2 has a replacement port 11 on the side near the drive management plate 3. The sealing side plate 2 is fixedly installed with a gate sealing assembly 12 by bolts on the side near the drive management plate 3. The top of the mounting plate 1 is fixedly installed with a gas sensor 13 located on the side of the through hole 9. A dust removal filter bag 14 is installed in the through hole 9. The dust removal filter bag 14 includes a filter cage and a cloth bag. The controller 15 is detachably installed on one side of the drive management plate 3.

[0026] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 2 This is a partial three-dimensional structural schematic diagram of the present invention; Figure 3 This is a three-dimensional structural schematic diagram of the pneumatic bag-lifting and pushing mechanism of the present invention; Figure 4 This is a three-dimensional structural diagram of the filter bag mounting mechanism of the present invention; Figure 5 This is a three-dimensional structural schematic diagram of the gate sealing assembly of the present invention; Figure 6 This is a three-dimensional structural diagram of the clamping block of the present invention.

[0027] The pneumatic bag-lifting and pushing mechanism 6 includes a cylinder 601, a pushing block 602, an electric push rod 603, a top plate 604, a stepper motor 605, and a filter bag torsion assembly 606. The cylinder 601 is bolted to the top of the drive platform 5. The pushing block 602 is welded to the output end of the cylinder 601. The electric push rod 603 is bolted to the top of the pushing block 602. The top plate 604 is welded to the output end of the electric push rod 603. The stepper motor 605 is bolted to the top plate 604. The output end of the stepper motor 605 is fixedly mounted on... Equipped with a filter bag torsion assembly 606, the starting cylinder 601 can push the push block 602 to the top of the mounting plate 1. Then, the top plate 604 can be lifted by the electric push rod 603. The lifted top plate 604 can drive the dust collector filter bag 14 to be replaced to move upward to a height that does not affect the lateral movement. The top plate 604 can drive the stepper motor 605 fixed thereto to move. The stepper motor 605 can drive the filter bag torsion assembly 606 to twist, so that the dust collector filter bag 14 is twisted to perform the replacement operation, and the damaged dust collector filter bag 14 and the filter bag to be replaced are twisted and replaced at the station.

[0028] The filter bag torsion assembly 606 includes a torsion plate 6061, two sets of first electromagnetic push rods 6062 and two sets of second electromagnetic push rods 6063, and a clamping block 6064. The torsion plate 6061 is welded to the output end of the stepper motor 605. The two sets of first electromagnetic push rods 6062 are bolted to both ends on the side closer to the dust collector filter bag 14, and the two sets of second electromagnetic push rods 6063 are bolted to both ends on the side away from the dust collector filter bag 14. The two sets of first electromagnetic push rods 6062 and the two sets of second electromagnetic push rods 6063 are connected to each other. The output end of the push rod 6063 is fixed with a clamping block 6064 by bolts. The torsion plate 6061 can torsion the two dust filter bags 14 in the working position. Before torsion, the second electromagnetic push rod 6063 needs to be activated to drive the clamping block 6064 to clamp the dust filter bag 14. After the dust filter bag 14 is clamped, it is easy to torsion and replace it. After the first electromagnetic push rod 6062 is activated, the clamping block 6064 can clamp the damaged dust filter bag 14, which makes it easy for the damaged dust filter bag 14 to be removed from the through hole 9.

[0029] The filter bag mounting mechanism 10 includes four sets of mounting blocks 101, two sets of bidirectional lead screws 102, two sets of stepper motors 103, a synchronization block 104, two sets of clamping blocks 105, a pressure ring 106, and a locking ring 107. The four sets of mounting blocks 101 are distributed and welded to the top of the mounting plate 1 and located at the four corners of the through hole 9. The two sets of bidirectional lead screws 102 are rotatably mounted inside the mounting blocks 101. The two sets of stepper motors 103 are respectively mounted on the mounting blocks 101 on the side away from the sealing side plate 2. The output ends of the two sets of stepper motors 103 are fixedly mounted to the two sets of bidirectional lead screws 102. Synchronization blocks 104 are welded to both sides of the two sets of clamping blocks 105. The synchronization blocks 104 are threadedly connected to the bidirectional lead screws 102. The pressure ring 106 is sleeved on the bottom surface of the dust collector filter bag 14, and the locking ring 107 is sleeved on the bottom surface of the dust collector filter bag 14. On the top surface of the filter bag 14, the surface of the clamping ring 107 is provided with a clamping groove 108 that engages with the clamping block 6064. When the dust filter bag 14 to be replaced is twisted to the through hole 9, the electric push rod 603 is used to move the dust filter bag 14 down to the top of the through hole 9 for replacement. Then, two sets of stepper motors 103 are started to rotate the two sets of bidirectional lead screws 102. The two sets of bidirectional lead screws 102 drive the synchronous block 104 connected to them to move closer to the dust filter bag 14. Then, the synchronous block 104 drives the clamping block 105 to move closer to the dust filter bag 14 to cooperate with the surface slope of the pressure ring 106 to clamp and lock it, ensuring the stable installation of the dust filter bag 14. At the same time, the clamping ring 107 can cooperate with the clamping block 6064 to clamp, move and transfer the dust filter bag 14.

[0030] The gate sealing assembly 12 includes a second cylinder 121, a connecting rod 122, a sealing plate 123, and a sealing ring. The second cylinder 121 is fixedly installed on the side of the sealing side plate 2 near the replacement port 11 by bolts. The connecting rod 122 is welded to the piston end of the second cylinder 121. The sealing plate 123 is slidably installed on the side of the replacement port 11. The sealing plate 123 is welded and fixed to the end of the connecting rod 122 away from the second cylinder 121. The sealing ring is sleeved on the surface of the sealing plate 123. When the second cylinder 121 is started, the sealing plate 123 can be driven up and down by the connecting rod 122. When the sealing plate 123 is driven upward, it can be separated from the replacement port 11, which facilitates the push block 602 to enter the mounting plate 1 for the replacement operation of the dust filter bag 14. The sealing ring can ensure that the downward movement of the sealing plate 123 can prevent flue gas leakage.

[0031] The sealing side plate 2 is welded with limiting strips 16 on both sides of the sealing plate 123 near the dust filter bag 14. The sealing plate 123 is sealed with the limiting strips 16 through the sealing ring. The limiting strips 16 can limit the surface of the sealing plate 123 around the perimeter, preventing the sealing plate 123 from tilting and shaking, while ensuring the sealing performance through the sealing ring that cooperates with it.

[0032] Anti-skewing rods 17 are welded to both sides of the pushing block 602 on the side away from the dust collector filter bag 14. Matching sleeves 18 that slide with the anti-skewing rods 17 are welded to both sides of the cylinder 601. Insertion slots 19 that mate with the dust collector filter bag 14 are provided on both sides of the torsion plate 6061. After the anti-skewing rods 17 and matching sleeves 18 are slidably installed, they can prevent the pushing block 602 from twisting or tilting, ensuring smooth pushing and preventing the dust collector filter bag 14 from tilting and impacting the replacement port 11 during movement.

[0033] A limiting block 20 is welded to the top of one side of the electric push rod 603. A slide rod 21 is slidably installed inside the limiting block 20. One end of the slide rod 21 is welded and fixed to the top plate 604. A stabilizing frame 22 is welded to the top of the push block 602. The top of the stabilizing frame 22 is rotatably connected to the output end of the second stepper motor 605. The limiting block 20 and the slide rod 21 can prevent the top plate 604 from shaking when the electric push rod 603 is driven up and down. At the same time, the stabilizing frame 22 can prevent the output end of the second stepper motor 605 from bending or tilting due to excessive weight, which would affect the stability of the internal rotor of the second stepper motor 605.

[0034] Working principle: During filtration by the dust collector filter bag 14, the gas sensor 13 installed on the top of the mounting plate 1 detects the content of harmful substances and particulate matter in the gas at the nearest position on one side of each dust collector filter bag 14. The detection data is transmitted to the controller 15. The controller 15 compares and analyzes the real-time data with the originally entered preset data. When the comparison data is abnormal, the controller 15 uses a built-in relay to control the opening and closing of the external solenoid valves connected to cylinder 1 601 and cylinder 2 121. Based on the abnormal data, the stepper motor 7 of the dust collector filter bag 14 starts to drive the screw 8 to rotate. The rotation of the screw 8 drives the drive platform 5 to move to the position of the damaged dust collector filter bag 14. (Cylinder 2 121 starts and drives the connecting rod 122 upward through the piston end.) The connecting rod 122 drives the sealing plate 123 to move upward and separate from the replacement port 11, making it easier for the push block 602 to enter the mounting plate 1 for replacement. (Before starting the cylinder 601, the new dust filter bag 14 to be replaced is installed on the torsion plate 6061, and the spare dust filter bag 14 is clamped by the two sets of second electromagnetic push rods 6063 near the side of the spare dust filter bag 14.) The starting cylinder 601 drives the push block 602 to the side near the dust filter bag 14. The push block 602 simultaneously drives the electric push rod 603 and the top plate 604. The top plate 604 drives the stepper motor 605 to move towards the dust filter bag 14 to be replaced. After moving to the limit position, the electric push rod 603 is started to drive the top plate 604, the stepper motor 605 and the torsion plate 6061 to move towards the side of the dust filter bag 14 to be replaced. The upper plate 6061 moves downward, aligning the two sets of first electromagnetic push rods 6062 installed inside the torsion plate 6061 with the clamping ring 107. Then, the first electromagnetic push rods 6062 are activated, causing the clamping block 6064 to engage with the clamping ring 107. After engagement, the stepper motor 103 starts, driving the synchronous block 104 on the side of the dust filter bag 14 that needs replacement to move away from the dust filter bag 14. The synchronous block 104 causes the clamping block 105 to separate from the pressure ring 106. Then, the electric push rod 603 is activated again, causing the top plate 604 to move upward. The top plate 604 synchronously drives the stepper motor 605 and the torsion plate 6061 to move upward. The torsion plate 6061, through the clamping block 6064, causes the dust filter bag 14 to move upward and separate from the through hole 9. At this time, the stepper motor 103 is activated. Stepper motor 605 drives torsion plate 6061 to rotate, causing the dust filter bag 14 to be replaced to switch positions with the damaged dust filter bag 14. Then, electric push rod 603 is activated to move top plate 604 downward, synchronously driving stepper motor 605 and torsion plate 6061 downward. Torsion plate 6061 drives the two sets of dust filter bags 14 downward through clamping block 6064. The dust filter bag 14 to be replaced enters through hole 9 (through hole 9 has a built-in proximity sensor 25 to facilitate the transmission of insertion and disengagement signals to controller 15 for smoother automatic control). Stepper motor 103 is then activated, driving the synchronous block 104 on the side of the dust filter bag 14 to be replaced to move closer to the dust filter bag 14 through its output end.Synchronizing block 104 drives clamping block 105 to abut and lock against clamping ring 106, completing the installation (this process obtains clamping signals through pressure sensor 26 embedded in clamping block 105, facilitating automatic control by controller 15). At this time, the second electromagnetic push rod 6063 is activated to separate clamping block 6064 from clamping ring 107 installed on the surface of the replaced dust filter bag 14. Then, the electric push rod 603 is activated to move top plate 604 upward. Top plate 604 synchronously drives stepper motor 605 and torsion plate 6061 upward. Torsion plate 6061 drives the replaced dust filter bag 14 upward through clamping block 6064. After moving to the limit position... When controller 15 receives a signal indicating that electric push rod 603 has completed its stroke, it activates cylinder 601, which drives push block 602 away from the replaced dust filter bag 14. Push block 602 simultaneously moves electric push rod 603 and top plate 604 out of mounting plate 1. After the movement is complete, cylinder 121 activates piston end to drive connecting rod 122 downwards. Connecting rod 122 moves sealing plate 123 downwards to seal replacement port 11, completing the replacement operation. Simultaneously, to prevent flue gas leakage during the replacement process, a sealing cover 23 is detachably mounted on top of drive management plate 3 via bolts. A maintenance plate is provided on one side of sealing cover 23 for future maintenance of the interior of sealing cover 23.
