Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically a bag dust removal device for garment production. Background Technology

[0002] A baghouse dust collector is a purification device that uses filter bags made of woven or needle-punched fibers as the filter medium. It achieves efficient gas-solid separation of dust-laden gas through multiple mechanisms, including sieving, inertial collision, diffusion, and electrostatic adsorption. Its working principle is based on a dynamic cycle of "filtration-cleaning": when the dust-laden gas flows through the filter bag, dust is trapped on the surface of the bag, forming a dust layer. The purified gas is discharged through the outlet. As the filtration resistance increases, the cleaning device periodically removes the accumulated dust using pulse jets, mechanical vibration, and other methods, restoring the filter bag's filtration performance. This is particularly useful for garment processing. For the industry, the cotton lint, chemical fiber fluff, and mixed dust generated during the production process have special properties such as strong fiber, light weight, easy entanglement, moisture absorption, and easy generation of static electricity. If left unchecked, they will not only seriously pollute the workshop and surrounding environment and threaten the respiratory health of operators, but also pose a major safety hazard of fire and explosion due to the presence of combustible dust. Therefore, using bag filters to capture such dust is not only an inevitable choice to meet environmental protection regulations and emission standards, but also a necessary technical measure to eliminate safety hazards at the source and ensure continuous and stable production.

[0003] In garment processing, the dust generated is mainly composed of fibrous materials such as cotton lint and synthetic fiber fluff. These materials are lightweight, easily entangled, highly hygroscopic, and often statically charged, making them prone to stubborn buildup and caking on the filter bag surface. This leads to a sharp decrease in filter bag permeability and a continuous increase in operating resistance. Therefore, frequent cleaning and even replacement of the filter bags are necessary to maintain basic equipment operation. However, traditional baghouse dust collectors are limited by their integrated box structure and densely arranged filter bags, lacking a design for independently extracting the filtration unit. Furthermore, the limited internal space and high operating height of the equipment further complicate the process. Due to the inherent dangers, maintenance personnel are forced to manually reach into the compartment to clean the dust using mechanical vibration and brushing. This invasive operation not only fails to reach the deep filter bags due to the limited space, resulting in uneven cleaning force and range, which damages the initial dust layer or causes alternating residual dust accumulation and a cleaning effect far below expectations, but more importantly, such operations can only be carried out after the entire machine is shut down. Frequent shutdowns and restarts not only disrupt the normal production rhythm but also affect the dust removal effect. Therefore, we propose a bag dust collector for garment production. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that invasive operations not only fail to reach deep filter bags due to limited space and extremely uneven cleaning force and range, resulting in the destruction of the initial dust layer or the alternating occurrence of residual dust accumulation, and the cleaning effect falling far short of expectations, but more importantly, such operations can only be carried out after the entire machine is shut down. Frequent shutdowns and restarts not only disrupt the normal production rhythm but also affect the dust removal effect.

[0005] To address the aforementioned technical problems, this application provides a bag dust collector for garment production, comprising a dust collection chamber, a bag body, and a suction port. The dust collection chamber contains multiple filter chambers, all of which are openable. Each filter chamber contains a guide rail, and an extension plate is slidably mounted within the guide rail. A sliding plate connected to the bag body is slidably mounted on the extension plate. Each filter chamber contains a disassembly / removal unit connected to the sliding plate, used to close the air inlet of the filter chamber before pulling the extension plate out of the filter chamber when replacing the bag body, allowing the bag body to move out of the filter chamber along with the sliding plate. A cleaning unit is provided within the filter chamber to clean dust adhering to the surface of the bag body when it becomes clogged.

[0006] In some embodiments, the disassembly unit includes a flow guide disposed in the filter chamber, through which dust-laden gas drawn in from the suction port is introduced into the filter chamber.

[0009] In some embodiments, the assembly includes a U-shaped limiting groove formed on an extension plate, a protrusion provided on the side of the sliding plate opposite to the limiting groove, the protrusion being slidably connected to the limiting groove, a knob rotatably provided on the extension plate, a baffle provided on the knob, the knob being connected to the extension plate via a damping shaft, a U-shaped plate provided on the sliding plate, slots formed on both sides of the U-shaped plate, a locking plate slidably provided in the slots, and the locking plate being connected to the bag body.

[0010] In some embodiments, the cleaning unit includes a cleaning component disposed on a U-shaped plate, which cleans the bag body. An actuator is disposed on the cleaning component, which drives the cleaning component to move along the surface of the bag body. A power component is disposed inside the filter chamber, which provides power to the actuator for operation.

[0011] In some embodiments, the cleaning component includes fixed plates disposed on both sides of a U-shaped plate. A guide rod and a reciprocating screw are rotatably disposed on the fixed plates respectively. A belt drive mechanism is disposed on the reciprocating screw located on both sides of the bag body. A lifting block is disposed on both the guide rod and the reciprocating screw, and the guide rod is slidably connected to the lifting block. The reciprocating screw is threadedly connected to the lifting block. A cleaning pipe is rotatably disposed on the lifting block. The cleaning pipe is connected to an external air source. Multiple sets of cleaning rods are disposed on the cleaning pipe. Air jet holes are opened on both sides of the cleaning rods on the cleaning pipe. A dust collection bin is disposed at the bottom of the dust collection bin. An exhaust pipe communicating with the bag body is disposed at the top of the dust collection bin. A differential pressure sensor is disposed in the exhaust pipe and is electrically connected to an electric actuator.

[0012] In some embodiments, the actuator includes a displacement shaft rotatably mounted on the lifting block, the displacement shaft being connected to a cleaning pipe, a displacement gear being mounted at the end of the displacement shaft away from the cleaning pipe, a displacement rack meshing with the displacement gear being mounted on the U-shaped plate, a positioning plate being mounted on the U-shaped plate, a rotating shaft being rotatably mounted on the positioning plate, drive gears meshing with each other being mounted on the rotating shaft and the reciprocating lead screw, a buffer groove being formed inside the rotating shaft, a buffer spring being mounted inside the buffer groove, a docking rod being slidably mounted inside the buffer groove, a transmission shaft being rotatably mounted on the side wall of the filter chamber, and a docking sleeve being mounted on the transmission shaft for use with the docking rod.

[0013] In some embodiments, the power component includes a merging pipe disposed at the top of the dust collection chamber, the merging pipe being connected to multiple exhaust pipes, a mounting plate disposed inside the merging pipe, a power shaft rotatably disposed on the mounting plate, a power blade disposed on the power shaft, a connecting shaft rotatably disposed inside the dust collection chamber, the connecting shaft passing through multiple filter chambers, and one end of the connecting shaft extending out of the dust collection chamber, a first connecting gear disposed on the transmission shaft, a second connecting gear disposed on the connecting shaft meshing with the first connecting gear, and a second belt drive mechanism disposed at one end of the power shaft and the connecting shaft located outside the dust collection chamber.

[0014] In some embodiments, the dust collection chamber is provided with multiple transparent observation windows at the locations of each filter chamber.

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

[0016] By dividing the dust collection chamber into multiple independent and openable filter chambers, and installing guide rails, sliding plates, and disassembly / removal units in each chamber, the system enables automatic closure of the air inlet in any filter chamber before the sliding plate carrying the filter bag is smoothly pulled out of the chamber along the guide rail when replacing the filter bag. This allows maintenance personnel to safely and conveniently replace the filter bag from the outside without entering the equipment, fundamentally solving the safety hazards and operational inconveniences of traditional equipment where maintenance personnel must risk entering confined spaces for manual cleaning or replacement due to the enclosed enclosure and densely packed filter bags. Furthermore, the design incorporates a timing control mechanism in the disassembly / removal unit that controls the sequence of closing the air inlet before pulling out the filter bag, ensuring... During the replacement process, dust-laden gas will not leak through the bypass, and the remaining filter chambers can still operate normally. This completely avoids the drawback of production interruption caused by the need to shut down the entire machine when replacing the filter bag body in traditional equipment. On this basis, the cleaning unit can perform targeted cleaning on the surface of the filter bag body when it is clogged. Combined with the residual pressure of the airflow in the pipeline driving the cleaning component to move back and forth along the surface of the filter bag body, and supplemented by the dual action of air jet and mechanical scraping, it achieves uniform and thorough removal of fibrous stubborn dust. This avoids the problem of dust removal failure caused by uneven force in traditional mechanical vibration or manual brushing, which leads to damage to the initial dust layer or alternating residual dust. It also makes full use of the system's own airflow energy and reduces additional energy consumption. Attached Figure Description

[0030] 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.

[0031] Example 1: Please refer to Figures 1-11This invention provides a technical solution: a dust removal device for garment production using cloth bags, comprising a dust collection chamber 1, a cloth bag body 2, and a suction port 3. The dust collection chamber 1 is characterized by having multiple filter chambers 4, all of which are openable. Each filter chamber 4 is equipped with a guide rail 5, and an extension plate 6 is slidably mounted within the guide rail 5. A sliding plate 61 connected to the cloth bag body 2 is slidably mounted on the extension plate 6. Each filter chamber 4 is equipped with a disassembly / removal unit 7 connected to the sliding plate 61, used to close the air inlet of the filter chamber 4 before pulling the extension plate 6 out of the filter chamber 4 when replacing the cloth bag body 2, allowing the cloth bag body 2 to move out of the filter chamber 4 along with the sliding plate 61. Each filter chamber 4 is equipped with a cleaning unit 11 for cleaning dust adhering to the surface of the cloth bag body 2 when it becomes clogged.

[0032] The disassembly and assembly unit 7 includes a flow guide 8 disposed in the filter chamber 4, through which the dust-laden gas sucked in by the suction port 3 is introduced into the filter chamber 4. The flow guide 8 is provided with a closing member 9, which is used to close the flow guide 8 when the bag body 2 is cleaned and replaced. The extension plate 6 is provided with an assembly 10, through which the bag body 2 is assembled and installed.

[0033] The flow guide 8 includes a ventilation chamber 81 disposed in the filter chamber 4, the ventilation chamber 81 being connected to the dust suction port 3, a protective chamber 84 installed in the filter chamber 4, a ventilation pipe 82 disposed in the protective chamber 84 and connected to the ventilation chamber 81, a plurality of discharge pipes 83 disposed on both sides of the ventilation pipe 82, one end of the discharge pipe 83 extending out of the protective chamber 84 and connected to the filter chamber 4, a closed shaft 86 rotatably disposed in the ventilation pipe 82, and one end of the closed shaft 86 penetrating the ventilation pipe 82, and a hemispherical sealing block 85 disposed on the closed shaft 86 that matches the inner diameter of the ventilation pipe 82.

[0034] The closure element 9 includes a closing gear 91 mounted on a closing shaft 86. A sliding chamber 92 is provided inside the protective chamber 84. A compression plate 93 is slidably mounted inside the sliding chamber 92. A compression spring 94 is provided inside the sliding chamber 92. An extension shaft 95 is provided on the side of the compression plate 93 away from the compression spring 94. One end of the extension shaft 95 passes through the side wall of the protective chamber 84 and is slidably connected to the side wall of the protective chamber 84. A closing rack 96 that meshes with the closing gear 91 is provided on the extension shaft 95. An electric push rod 97 connected to the extension plate 6 is provided inside the guide rail 5.

[0035] The assembly 10 includes a U-shaped limiting groove 101 formed on the extension plate 6. A protrusion 102 is provided on the side of the sliding plate 61 opposite to the limiting groove 101. The protrusion 102 is slidably connected to the limiting groove 101. A knob 103 is rotatably provided on the extension plate 6. A baffle 104 is provided on the knob 103. The knob 103 is connected to the extension plate 6 through a damping shaft. A U-shaped plate 105 is provided on the sliding plate 61. A slot 106 is formed on both sides of the U-shaped plate 105. A locking plate 107 is slidably provided in the slot 106. The locking plate 107 is connected to the bag body 2.

[0036] When the filter bag body 2 needs to be replaced, first control the electric push rod 97 to push the extension plate 6 to move the sliding plate 61 and U-shaped plate 105 away from the protective chamber 84. After the extension plate 6 and U-shaped plate 105 move away from the protective chamber 84, the extension shaft 95 is no longer compressed by the U-shaped plate 105. At this time, the compression plate 93 in the sliding chamber 92 moves under the push of the compression spring 94, thereby driving the extension shaft 95 to move synchronously. The movement of the extension shaft 95 drives the closed rack 96 set on it to move, thereby pushing the closed gear 91 meshing with the closed rack 96 to rotate. The rotation of the closed gear 91 drives the closed shaft 86 to rotate. The rotation of the closed shaft 86 drives the sealing block 85 to deflect, thereby blocking the vent pipe 82. At this time, the filter chamber 4 no longer takes in air.

[0037] After completing the above operations, the operator opens the filter chamber 4, then rotates the knob 103 to deflect the baffle 104, causing the sliding plate 61 to be released from its limit. After that, the operator pulls the sliding plate 61, causing the U-shaped plate 105 on the sliding plate 61 and the bag body 2 to extend out of the filter chamber 4 simultaneously. When the bag body 2 is fully extended, the operator pulls the locking plate 107 upwards to disengage the bag body 2 from the U-shaped plate 105. After removing the old bag body 2, a new bag body 2 is inserted, and then the bag body 2 is sent into the filter chamber 4 and locked again. After completion, the operator controls the electric push rod 97 to reset the U-shaped plate 105 and repress the extension shaft 95, which can release the blockage of the vent pipe 82 and allow the bag body 2 to return to the working state.

[0038] By cleverly combining the mechanical linkage of the extension plate 6 and sliding plate 61 driven by the electric actuator 97 with the closing member 9, a timing control mechanism of "prioritizing the pulling of the bag body 2 and automatically cutting off the airflow" is formed. When the bag body 2 needs to be replaced, the electric actuator 97 pushes the extension plate 6 outward, so that the U-shaped plate 105 releases the pressure on the extension shaft 95. The compression spring 94 then pushes the closing rack 96, closing gear 91 and sealing block 85 to automatically seal the vent pipe 82. This purely mechanical sequential control can ensure that the air inlet of the filter chamber 4 is reliably sealed before the bag body 2 is pulled out without relying on additional electrical sensors or manual judgment. This completely avoids the safety risks of dust-laden gas being sprayed out during the replacement process due to misoperation or forgetting to close the valve, which may pollute the environment or injure the operator, as is common in traditional equipment.

[0039] The combined design of guide rail 5, extension plate 6, sliding plate 61, and U-shaped plate 105 allows the filter bag body 2 to be slidably pulled out of the filter chamber 4 along guide rail 5 when replacement is needed. Maintenance personnel no longer need to manually disassemble and install the filter bag body 2 by reaching into the narrow, dark, and dusty interior of the equipment as in traditional methods. Instead, they can perform the insertion and removal of the filter bag body 2 in an open and safe external space. This design fundamentally changes the maintenance operation mode, avoiding occupational health and safety hazards such as suffocation, collisions, and dust inhalation caused by working in confined spaces, and significantly reducing the difficulty of operation and physical exertion.

[0040] By combining a U-shaped plate 105, a slot 106, a locking plate 107 on the sliding plate 61, and a limiting groove 101, a protrusion 102, a knob 103, and a baffle 104 on the extension plate 6, a modular quick-release structure for the bag body 2 is formed. When replacing, simply rotate the knob 103 to release the limiting position of the sliding plate 61, pull out the sliding plate 61, and then lift the locking plate 107 upwards to separate the bag body 2. When installing a new bag body 2, simply insert it in the opposite direction and push it back. This structure can complete the assembly and disassembly of the bag body 2 without any tools. Furthermore, the sliding cooperation between the locking plate 107 and the slot 106 ensures the positional accuracy of the bag body 2 after installation, avoiding the cumbersome operation and inconsistent tightness caused by manual binding or bolt fixing, and significantly shortening the time required for a single maintenance.

[0041] Finally, since each filter chamber 4 adopts an independent chamber design, and the air inlet of the chamber is automatically closed through the above-mentioned mechanical linkage when the filter bag body 2 is replaced, the remaining filter chambers 4 can continue to filter dust-laden gas normally. The entire dust removal system does not need to be shut down due to the maintenance of a single chamber. This design is particularly important for continuous production scenarios such as garment processing. It effectively avoids production interruptions, wasted time, and additional impacts on the fan and pipeline system caused by the frequent shutdowns for cleaning or replacement of filter bag bodies 2 due to blockage of traditional equipment.

[0042] The cleaning unit 11 includes a cleaning component 12 disposed on a U-shaped plate 105, which cleans the bag body 2. An actuator 13 is disposed on the cleaning component 12, which drives the cleaning component 12 to move along the surface of the bag body 2. A power component 14 is disposed in the filter chamber 4, which provides power for the actuator 13 to work.

[0043] The cleaning component 12 includes fixed plates 121 disposed on both sides of the U-shaped plate 105. Guide rods 122 and reciprocating screws 123 are rotatably mounted on the fixed plates 121. Belt drive mechanisms 124 are mounted on the reciprocating screws 123 located on both sides of the bag body 2. Lifting blocks 125 are mounted on both the guide rods 122 and the reciprocating screws 123. The guide rods 122 and the lifting blocks 125 are slidably connected, and the reciprocating screws 123 are threadedly connected to the lifting blocks 125. A cleaning pipe 126 is rotatably installed and connected to an external air source. Multiple cleaning rods 127 are installed on the cleaning pipe 126. Air jet holes 128 are opened on both sides of the cleaning rods 127 on the cleaning pipe 126. A dust collection bin 129 is installed at the bottom of the dust collection bin 1. An exhaust pipe 1211 connected to the filter bag body 2 is installed at the top of the dust collection bin 1. A differential pressure sensor 1210 is installed in the exhaust pipe 1211 and is electrically connected to the electric push rod 97.

[0044] The actuator 13 includes a displacement shaft 131 rotatably mounted on the lifting block 125. The displacement shaft 131 is connected to the cleaning pipe 126. A displacement gear 132 is provided at the end of the displacement shaft 131 away from the cleaning pipe 126. A displacement rack 133 that meshes with the displacement gear 132 is provided on the U-shaped plate 105. A positioning plate 134 is provided on the U-shaped plate 105. A rotating shaft 135 is rotatably mounted on the positioning plate 134. A drive gear 136 that meshes with each other is provided on the rotating shaft 135 and the reciprocating screw 123. A buffer groove 137 is provided in the rotating shaft 135. A buffer spring 138 is provided in the buffer groove 137. A docking rod 139 is slidably mounted in the buffer groove 137. A transmission shaft 1311 is rotatably mounted on the side wall of the filter chamber 4. A docking sleeve 1312 that cooperates with the docking rod 139 is provided on the transmission shaft 1311.

[0045] When the bag body 2 is clogged with dust, the differential pressure sensor 1210 inside the exhaust pipe 1211 detects a pressure change. At this time, the electric push rod 97 is driven by the controller to push the extension plate 6 and the sliding plate 61, causing the U-shaped plate 105 to move. This causes the U-shaped plate 105 to disengage from the extension shaft 95, no longer compressing the extension shaft 95, thus blocking the vent pipe 82. Furthermore, as the U-shaped plate 105 moves, the docking rod 139 mounted on it engages with the docking sleeve 1312, and the docking sleeve 131... Driven by the rotation of the 2, the rotating rod 139 rotates, causing the rotating shaft 135 to rotate synchronously. The rotating shaft 135, in turn, drives the reciprocating screw 123 to rotate via the meshing drive gear 136. The reciprocating screw 123 then moves the lifting block 125 and the cleaning pipe 126 up and down, cleaning the dust and debris adhering to the surface of the bag body 2. Meanwhile, the top of the cleaning rod 127 is made of rubber, effectively preventing damage to the bag body 2. The air jet vent 128 design assists in cleaning the bag. The dust on the surface of the main body 2 is cleaned, and the air jet holes 128 are set on both sides of the cleaning rod 127 to effectively prevent the fibers in the impurities from adhering to the cleaning rod 127. When the cleaning rod 127 moves up and down, it will drive the displacement shaft 131 connected to the cleaning rod 127 on the lifting block 125 to move up and down. When the displacement shaft 131 moves up and down, the displacement gear 132 set on it moves accordingly. When the displacement gear 132 moves, it meshes with the displacement rack 133, and thus rotates under the push of the displacement rack 133, which in turn drives the displacement shaft 131 to rotate. The rotation of the displacement shaft 131 drives the cleaning rod 127 to rotate, further improving the cleaning effect of the bag body 2. When the bag body 2 is cleaned, the differential pressure sensor 1210 detects that the pressure has recovered, and will drive the U-shaped plate 105 to reset again and continue the dust removal work. The positioning plate 134 is detachably installed on the U-shaped plate, so when replacing the bag body 2, it can be removed together with the rotating shaft 135 to avoid affecting the removal of the bag body 2.

[0046] The power unit 14 includes a confluence pipe 141 disposed at the top of the dust collection chamber 1. The confluence pipe 141 is connected to multiple exhaust pipes 1211. A mounting plate 142 is disposed inside the confluence pipe 141. A power shaft 143 is rotatably disposed on the mounting plate 142. A power blade 144 is disposed on the power shaft 143. A connecting shaft 145 is rotatably disposed inside the dust collection chamber 1. The connecting shaft 145 passes through multiple filter chambers 4, and one end of the connecting shaft 145 extends out of the dust collection chamber 1. A first connecting gear 146 is disposed on the transmission shaft 1311. A second connecting gear 147 that meshes with the first connecting gear 146 is disposed on the connecting shaft 145. A second belt drive mechanism 148 is disposed at the end of the power shaft 143 and the connecting shaft 145 located outside the dust collection chamber 1.

[0047] The filtered gas is discharged through the confluence pipe 141. When the gas flows in the pipe, it drives the power blade 144 to rotate, which in turn drives the power shaft 143 to rotate. The rotation of the power shaft 143 drives the connecting shaft 145 to rotate through the belt drive mechanism 148. The rotation of the connecting shaft 145 drives the connecting gear 147 to rotate. The rotation of the connecting gear 147 drives the connecting gear 146 meshing with it to rotate, which in turn drives the transmission shaft 1311 and the docking sleeve 1312 connected to the connecting gear 146 to rotate.

[0048] By installing a differential pressure sensor 1210 inside the exhaust pipe 1211 and electrically connecting the differential pressure sensor 1210 to the electric actuator 97, a fully automatic closed-loop control chain of "differential pressure detection—signal triggering—action execution—cleaning completion—automatic reset" is formed. When the filter bag body 2 experiences increased filtration resistance due to fiber dust accumulation, the system can automatically identify the blockage state without manual intervention and initiate the subsequent dust removal process. After cleaning is completed and the differential pressure is restored, the system can automatically reset the cleaning mechanism and restore normal filtration of the chamber. This design completely changes the passive mode of traditional equipment that relies on manual inspection, experience to judge blockage, and then manually activate the dust removal device, realizing the dust removal device's... The system actively senses and adaptively adjusts its own operating conditions. Simultaneously, a power system utilizing the residual pressure of the exhaust airflow to drive the cleaning mechanism is designed and constructed. The filtered clean air, as it flows through the confluence pipe 141, naturally pushes the power blades 144 to rotate. This rotational power is transmitted via a mechanical transmission path to the reciprocating screws 123, lifting blocks 125, and cleaning pipes 126 within each filter chamber 4. No additional power sources such as motors or cylinders are required throughout the process. This design fully utilizes the airflow energy that would otherwise be wasted in the system, while avoiding the electrical wiring, control programming, increased energy consumption, and potential failure points associated with adding external power equipment. It is particularly suitable for production environments such as garment processing where equipment simplicity is paramount.

[0049] The reciprocating screw 123 and guide rod 122 work together to achieve uniform up-and-down movement of the lifting block 125. At the same time, the meshing of the displacement shaft 131, displacement gear 132 and displacement rack 133 causes the cleaning pipe 126 to automatically rotate during the lifting process, forming a composite cleaning trajectory of "lifting and rotating at the same time". The multiple sets of cleaning rods 127 set on the cleaning pipe 126 are in contact with the surface of the filter bag body 2 with rubber material. They can effectively remove fibrous stubborn dust through mechanical scraping, and the flexible material avoids scratching or excessive compression of the filter bag fibers. The air jet holes 128 opened on both sides of the cleaning rod 127 spray compressed air simultaneously during cleaning. On the one hand, the loosened dust is blown away from the surface of the filter bag body 2, and on the other hand, the airflow is used to prevent fibrous impurities from getting entangled on the cleaning rod 127. The synergistic effect of pneumatic and mechanical forces significantly improves the uniformity and thoroughness of dust removal, avoiding the dust removal failure problem of the initial dust layer being destroyed and residual dust alternating under the traditional single vibration or back-blowing method.

[0050] Meanwhile, the design uses a connecting shaft 145 to pass through multiple filter chambers 4, and utilizes the meshing of the connecting gear 146 on the transmission shaft 1311 of each chamber and the connecting gear 147 on the connecting shaft 145 to synchronously distribute the rotational motion of the power shaft 143 to all filter chambers 4. Regardless of whether the chamber to be cleaned is single or multiple, the cleaning mechanism in each chamber has the ability to start at any time, and there is no need to configure a separate power source for each chamber. This centralized drive and zoned execution design greatly simplifies the power transmission chain, reduces the number of motors, belts, and control lines, and improves the compactness and reliability of the overall structure.

[0051] Furthermore, through the design of the buffer spring 138 and the docking rod 139, the U-shaped plate 105 can automatically and flexibly dock with the docking sleeve 1312 on the transmission shaft 1311 when it is reset, without the need for manual alignment adjustment. This structure not only ensures the reliable transmission of power during dust removal, but also avoids spatial interference between the cleaning mechanism and the bag body 2 replacement operation, realizing the coexistence and switching of the "dust removal function" and the "replacement function" on the same module.

[0052] Example 2: Please refer to Figure 12 This invention provides a technical solution: multiple transparent observation windows 15 are provided on the dust collection chamber 1 at the positions of each filter chamber 4. Through external visualization, operators can visually observe the dust accumulation status of the filter bag body 2 in each filter chamber 4, the operation of the cleaning mechanism, and the positional relationship between the sliding plate 61 and the locking plate 107 at any time without opening the chamber door. This allows for prediction of the degree of blockage, precise grasp of the cleaning timing, and confirmation of the status before maintenance operations without interrupting equipment operation. This design avoids the safety hazards, negative pressure leakage, and dust escape risks caused by frequent opening of the cover for inspection. It also facilitates maintenance personnel to quickly locate the chambers that need to be treated before performing filter bag body 2 replacement or cleaning operations. Combined with the modular drawer-type structure, it realizes "precise diagnosis and targeted maintenance", significantly improving the efficiency of daily inspections and the controllability of equipment operation.
