Description

Technical Field

[0001] This invention relates to the field of waste gas adsorption technology, and in particular to a waste gas treatment device that integrates a zeolite rotor and an RTO. Background Technology

[0002] In existing integrated zeolite rotor and RTO waste gas treatment equipment, the pre-filter plate, as the core component of waste gas pretreatment, needs to be regularly disassembled and replaced to ensure the purification efficiency of the whole machine. However, the replacement of filter plates currently relies mainly on hoisting equipment to directly lift and lower them, while manual calibration and assistance are provided for the lowering of the filter plates. When the hoisting equipment becomes unstable or the lowering speed is abnormal, it cannot be locked in time, posing a safety hazard of filter plate falling. At the same time, the filter plates are prone to falling too fast due to their own gravity during the lowering process, causing damage to the plate body and deformation of the bottom support components due to impact. Therefore, the overall filter plate replacement operation is inefficient and the installation quality is not stable enough, making it difficult to meet the high-efficiency operation and maintenance requirements of integrated waste gas treatment equipment. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a waste gas treatment device that integrates a zeolite rotor and an RTO.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a waste gas treatment device integrating a zeolite rotor and an RTO, comprising a waste gas treatment chamber and several filter plates. Vertical ladders are installed on both sides of the exterior of the waste gas treatment chamber to facilitate operators climbing to the upper part of the chamber. One end of the waste gas treatment chamber is connected to an external air inlet pipe, and the other end is connected to an exhaust pipe for conveying the waste gas after adsorption in the RTO combustion zone. The filter plates are located on the exterior of the waste gas treatment chamber near the air inlet pipe, and the interior of the waste gas treatment chamber, away from the air inlet pipe, is equipped with zeolite rotors. In the zeolite rotor area, the filter plates are used to adsorb and treat the incoming waste gas. After the adsorbed waste gas is treated, it enters the zeolite rotor area for further treatment. After the waste gas is further adsorbed and purified in the zeolite rotor area, it enters the RTO device through the exhaust pipe for combustion and purification, thereby achieving an integrated waste gas treatment effect. The upper part of the waste gas treatment box has installation slots corresponding to the number of filter plates. The filter plates are installed by lowering them from the installation slots into the waste gas treatment box. Each filter plate has a transmission vertical rack fixedly installed on both sides of its exterior. Both sides of the upper end of the exhaust gas treatment box are equipped with speed reduction buffer components, which are used to slow down the filter plates and lower them into the exhaust gas treatment box when the filter plates are replaced or installed. Each deceleration buffer assembly also includes a side frame, which is fixedly installed on the side of the exhaust gas treatment box. A transverse sliding slot is opened on the side of the side frame near the mounting slot. The transverse sliding slot is T-shaped. A translational seat is slidably connected inside the transverse sliding slot. A fixed roller is fixedly connected to the end of the translational seat away from the transverse sliding slot. An annular rotary damper is fixedly fitted on the outside of the fixed roller. One end of the annular rotary damper is fixedly connected to the outside of the translational seat. A rotating deceleration sleeve is fixedly connected to the end of the annular rotary damper shaft away from the translational seat. A connecting ring is fixedly connected to the end of the rotating deceleration sleeve away from the annular rotary damper. A driven tooth is fixedly connected to the end of the connecting ring away from the rotating deceleration sleeve. The driven tooth rotates and fits around the outside of the fixed roller. A synchronous transmission toothed belt is meshed with the outside of the driven tooth. A driving tooth is meshed with the inside of the synchronous transmission toothed belt on the side away from the driven tooth. A driving positioning shaft is movably fitted inside the driving tooth. The driving positioning shaft is fixedly connected to the outside of the translational seat.

[0005] As a preferred embodiment of the present invention, the rotating deceleration sleeve is designed in the shape of a ring. The outer ring surface of the rotating deceleration sleeve is provided with a plurality of abutting grooves identical to those inside. A protective shell is provided outside the abutting grooves, and the protective shell is movably sleeved on the outside of the driven teeth.

[0006] As a preferred embodiment of the present invention, a stop and anti-fall component is provided on the outside of the rotating slow-speed sleeve. The anti-fall device includes an anti-fall sleeve, which is fixedly connected to the end of the translation platform away from the interior of the transverse groove. The anti-fall sleeve is fitted over the outside of the rotating slowing sleeve. The upper end of the anti-fall sleeve has a hinge groove. A stop pawl is rotatably connected inside the hinge groove via a pin. The lower end of the stop pawl extends and inserts into the interior of the abutment groove. An operating handle for easy gripping is fixedly connected to the upper end of the stop pawl.

[0007] As a preferred embodiment of the present invention, a limit plate hinge seat is fixedly connected to the outer side of the stop sleeve, and a pawl limit plate is rotatably connected inside the limit plate hinge seat. The pawl limit plate is U-shaped.

[0008] As a preferred embodiment of the present invention, a guide assembly is provided on the outside of the translation platform. The guide assembly includes an upper guide seat body, which is fixedly connected to the end of the translation platform away from the transverse groove. The side of the upper guide seat body away from the translation platform is provided with an alignment guide groove adapted to the thickness of the filter plate. A guide platform is fixedly installed on the upper end of the guide platform. The guide platform is an inverted trapezoidal platform, and the interior of the guide platform is provided with a guide groove for guiding the placement of the filter plate.

[0009] As a preferred embodiment of the present invention, the side frame platform is provided with a locking component for positioning on its exterior. The locking assembly includes a positioning insert plate, a traction slot, a vertical slot, and several positioning slots. The traction slot is located outside the side frame and communicates with the interior of the transverse sliding slot. The positioning insert plate is movably connected inside the traction slot and extends into the transverse sliding slot. Several positioning slots are located inside the transverse sliding slot. The vertical slot is located outside the transverse sliding slot and communicates with its interior. The positioning insert plate is movably connected inside the vertical slot, and the lower end of the positioning insert plate is inserted into the interior of the positioning slot.

[0010] As a preferred embodiment of the present invention, a lifting ring that is easy to grip is fixedly installed on the upper end of the positioning plate; The positioning insert has a spring mounting cavity inside, and a partition is movably connected inside the spring mounting cavity. The partition is fixedly connected inside the vertical slot, and a guide rod is movably connected inside the partition. The guide rod is vertically fixed inside the spring mounting cavity, and a return spring is movably fitted outside the guide rod. The two ends of the return spring are respectively fixedly connected to the sides of the partition and the inner wall of the spring mounting cavity facing each other. The return spring applies a pre-tightening force to the positioning insert and the partition, so that the positioning insert continues to provide power downward in the initial state.

[0011] As a preferred embodiment of the present invention, a top cover plate is provided on the outside of the mounting slot. The top cover plate is installed on the upper end of the mounting slot and is used to close it. A top beam plate is fixedly connected to the outside of the top cover plate. Several handles are provided on both sides of the outside of the top beam plate. A limiting side plate and a hanging beam plate are respectively provided on both sides of the outside of the top cover plate. The hanging beam plate is fixedly connected to the side of the outside of the exhaust gas treatment box. A horizontal slot is provided at the lower end of the hanging beam plate to facilitate the placement of the top cover plate. A hanging slot is opened on the side of the hanging beam plate near the top beam plate. The hanging slot is an L-shaped slot. The limiting side plate is fixedly connected to the side of the upper end of the exhaust gas treatment box away from the hanging beam plate and is used to limit the installation of the top cover plate so that the top cover plate can be quickly positioned above the mounting slot.

[0012] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention uses a translational platform to drive the entire slowing mechanism to move flexibly along the transverse groove, achieving precise alignment and meshing between the synchronous transmission toothed belt and the vertical transmission rack on the side of the filter plate. During the filter plate lowering and installation process, it provides a continuous and stable damping and slowing effect, effectively counteracting the downward force of the filter plate's gravity, smoothly controlling the lowering speed, and avoiding collision damage and installation misalignment caused by rapid descent of the filter plate. This ensures that the entire filter plate installation process is stable and controllable, effectively improving the operational safety and installation accuracy of filter plate replacement operations. At the same time, it ensures the operational stability of the pretreatment section, maintains the overall exhaust gas purification efficiency, and fully adapts to the high-efficiency operation and maintenance requirements of integrated exhaust gas treatment equipment.

[0013] 2. This invention combines one-way follow-up passage with instant stop locking function. During normal filter plate lowering operation, it will not obstruct the transmission operation. When the lowering speed is abnormal, the hoisting equipment is unstable, or temporary suspension is required, the transmission link can be quickly locked to achieve instant suspension and anti-fall of the filter plate. At the same time, the matching pawl limit structure forms a mechanical locking safety, which can effectively prevent the stop pawl from being loosened by external force vibration or accidental contact, greatly improving the reliability of the locking state, avoiding equipment damage and safety accidents caused by filter plate falling, and effectively ensuring the safety and stability of filter plate installation operation.

[0014] 3. This invention features automatic centering and vertical limiting functions, which can guide and align the hoisted filter plates, effectively limiting horizontal swaying during the lowering process. At the same time, it automatically aligns the vertical transmission racks on both sides of the filter plate with the synchronous transmission belt below, significantly reducing the difficulty of hoisting and alignment, ensuring accurate and smooth subsequent meshing transmission, providing a reliable alignment foundation for slow lowering operations, and effectively improving the efficiency and alignment accuracy of filter plate installation.

[0015] 4. This invention achieves precise gear positioning and automatic locking of the translational platform, effectively preventing displacement of the platform during operation. It ensures that the upper guide seat and the guide table are always precisely aligned above the installation slot, guaranteeing the accuracy of filter plate insertion and alignment. At the same time, it ensures that the synchronous transmission belt and the transmission vertical rack maintain a stable and precise meshing transmission state, providing a stable and reliable position reference for the slow installation of the filter plate and fall protection.

[0018] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0019] Example: Figure 1 and Figure 11 As shown, a waste gas treatment device integrating a zeolite rotor and an RTO is disclosed. The device adopts an integrated structure design and is composed of a waste gas pretreatment module, a zeolite rotor adsorption concentration unit, an RTO regenerative combustion purification unit, and a gas transmission and distribution system. The functional units are compactly arranged and the gas paths are directly connected, realizing the integrated treatment of waste gas from pretreatment, adsorption concentration to high-temperature incineration purification.

[0020] The waste gas pretreatment module uses the waste gas treatment box 10 as its core carrier. Several filter plates 11 are installed in the pre-treatment chamber inside the box, forming the first pretreatment step after the waste gas enters the system. This step intercepts large particulate matter, flocculent matter, and some easily adsorbed components in the waste gas, protecting the downstream zeolite rotor from contamination. The zeolite rotor adsorption and concentration unit is integrated into the downstream chamber inside the waste gas treatment box 10, arranged in the same chamber as the pre-filter plates 11, forming an integrated chamber for pretreatment and concentration adsorption, significantly reducing equipment requirements. The system is designed to minimize floor space and pipeline resistance. The RTO regenerative combustion unit is located adjacent to the exhaust side of the waste gas treatment box 10. Its intake end is directly connected to the desorption outlet of the zeolite rotor area through the exhaust pipe. It can receive the high-concentration waste gas produced by the zeolite rotor desorption and perform high-temperature oxidation and decomposition. The purified clean gas is finally discharged through the exhaust chimney in compliance with standards. The gas distribution system includes external intake pipes, internal air distribution channels, rotor desorption air paths, and exhaust pipes, realizing the orderly transportation and switching of waste gas between various functional units.

[0021] In current waste gas pretreatment modules, the pre-filter plates, as the core components of waste gas pretreatment, need to be regularly disassembled and replaced to ensure the overall purification efficiency of the machine. However, the replacement of filter plates currently relies mainly on hoisting equipment for direct lifting and lowering, with manual calibration and assistance during the lowering process. When the hoisting equipment becomes unstable or the lowering speed is abnormal, it cannot be locked in time, posing a safety hazard of filter plates falling. At the same time, the filter plates are prone to falling too fast due to their own gravity during the lowering process, causing damage to the plate body and deformation of the bottom support components due to impact. Therefore, the overall filter plate replacement operation is inefficient and the installation quality is not stable enough, making it difficult to meet the needs of efficient operation and maintenance of integrated waste gas treatment equipment.

[0022] Therefore, improvements were made to the exhaust gas pretreatment module, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The filter plate 11 is a filter plate for adsorbing exhaust gas. The upper end of the filter plate 11 has a lifting lug slot for easy hoisting. Vertical ladders are installed on both sides of the exhaust gas treatment box 10 to facilitate operators climbing to the upper part of the exhaust gas treatment box 10. One end of the exhaust gas treatment box 10 is connected to an external air inlet pipe, and the other end is connected to an exhaust pipe for transporting the exhaust gas after adsorption in the RTO combustion zone. The filter plate 11 is located on the outside of the exhaust gas treatment box 10 near the air inlet pipe. The inside of the exhaust gas treatment box 10, away from the air inlet pipe, is the zeolite rotor area. The filter plate 11 is used to adsorb and treat the incoming exhaust gas, and after treatment, the adsorbed exhaust gas is then allowed to enter the zeolite rotor. The waste gas is treated within the designated area. After further adsorption and purification in the zeolite rotor area, it enters the RTO device through the exhaust pipe for combustion purification, thus achieving integrated waste gas treatment. The upper part of the waste gas treatment box 10 has mounting slots 18 corresponding to the number of filter plates 11. A top cover plate 17 is installed on the outside of the mounting slots 18 to seal them. A top beam plate 15 is fixedly connected to the outside of the top cover plate 17. Several handles are provided on both sides of the top beam plate 15. Limiting side plates 16 and hanging beam plates 13 are respectively provided on both sides of the top cover plate 17. The hanging beam plates 13 are fixedly connected to... The lower end of the hanging beam plate 13, attached to the side of the exterior of the exhaust gas treatment box 10, is provided with a horizontal slot to facilitate the placement of the top cover plate 17. A hanging slot 14, L-shaped, is provided on the side of the hanging beam plate 13 near the top beam plate 15. A limiting side plate 16 is fixedly connected to the upper end of the exhaust gas treatment box 10 away from the hanging beam plate 13, used to limit the installation of the top cover plate 17, allowing it to be quickly positioned above the mounting slot 18. After the top cover plate 17 is installed outside the mounting slot 18, the translation platform 211 can move the protective housing 28 to above the top cover plate 17. At this time, the bottom of the protective housing 28 is flush with the surface of the top cover plate 17. The surfaces are fitted together to fix the top cover plate 17. The filter plate 11 is installed by falling into the exhaust gas treatment box 10 from below the mounting slot 18. Vertical guide rails 60 are installed on both sides of the inner wall of the exhaust gas treatment box 10. The vertical guide rails 60 are used to further guide the filter plate 11 into the exhaust gas treatment box 10. A filter plate buffer support 61 is set below the vertical guide rails 60. The filter plate buffer support 61 is U-shaped and has a silicone buffer pad inside. When the bottom of the filter plate 11 is lowered into the filter plate buffer support 61, the filter plate buffer support 61 buffers the filter plate 11 to avoid damage caused by the filter plate buffer support 61 touching the bottom.

[0023] Operators operate the hoisting equipment and, in conjunction with manual labor, hold the top beam plate 15, driving the top cover plate 17 to be smoothly lifted along the vertical inner wall of the mounting slot 18. During this process, the end of the top beam plate 15 near the hanging beam plate 13 simultaneously embeds into the vertical section of the hanging slot 14, sliding smoothly upwards along the slot wall until the upper surface of the top beam plate 15 abuts against and fits against the top inner wall of the hanging slot 14, completing the full vertical lifting stroke. Subsequently, the operators horizontally push the top beam plate 15 along the transverse section of the hanging slot 14, driving the top... The top cover plate 17 is moved horizontally to one side of the hanging beam plate 13, so that the plate body of the top cover plate 17 is gradually inserted into the horizontal groove opened at the bottom of the hanging beam plate 13 until the top cover plate 17 is completely removed from directly above the mounting slot 18, fully exposing the mounting slot 18 and providing sufficient vertical operating space for filter plate disassembly and assembly. At this time, the filter plate 11 can be lifted and removed vertically from the inside of the exhaust gas treatment box 10 by hooking the upper end of the filter plate 11 with the lifting lug slot, thus completing the removal of the old filter plate.

[0024] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8Each filter plate 11 has a transmission rack 12 fixedly installed on both sides of its exterior. Speed ​​reduction buffer assemblies are provided on both sides of the upper end of the exhaust gas treatment box 10 to slow down the filter plates 11 and lower them into the exhaust gas treatment box 10 during replacement and installation. Each speed reduction buffer assembly also includes a side support platform 20, which is fixedly installed on the outer side of the exhaust gas treatment box 10. A transverse sliding slot 21 is provided on the side of the side support platform 20 near the mounting slot 18. The transverse sliding slot 21 is T-shaped. A translational seat 211 is slidably connected inside the transverse sliding slot 21. The translational seat 211 and the transverse sliding slot 21 are adapted to slide inside the transverse sliding slot 21, and are connected by the T-shaped slot of the transverse sliding slot 21. To limit movement and prevent ejection from the transverse groove 21, a fixed roller 25 is fixedly connected to one end of the translation platform 211 away from the interior of the transverse groove 21. An annular rotary damper 210 is fixedly fitted onto the outside of the fixed roller 25. One end of the annular rotary damper 210 is fixedly connected to the outside of the translation platform 211. The annular rotary damper 210 consists of a housing and a rotating shaft. The housing is an annular shell fixed to the outside of the translation platform 211, with an annular cavity inside filled with silicone oil. The rotating shaft is an annular rotor with blades on its outer ring, rotatably connected to the annular cavity of the housing. The blades of the rotating shaft divide the annular cavity into multiple independent arc-shaped oil chambers. When the rotating shaft rotates, causing its blades to rotate within the annular cavity, the blades... The silicone oil is forced to flow from one cavity to another through the throttling gap between the sheet and the inner wall of the annular cavity, generating a damping torque. A rotating retarder 22 is fixedly connected to the end of the rotating shaft of the annular rotary damper 210 away from the translational platform 211. A connecting ring 212 is fixedly connected to the end of the rotating retarder 22 away from the annular rotary damper 210. A driven tooth 26 is fixedly connected to the end of the connecting ring 212 away from the rotating retarder 22. The driven tooth 26 rotatably fits around the outside of the fixed roller 25. A synchronous transmission toothed belt 27 is meshed with the outside of the driven tooth 26. A driving tooth 23 is meshed with the inside of the synchronous transmission toothed belt 27 on the side away from the driven tooth 26. A driving positioning shaft 24 is movably fitted inside the driving tooth 23. The driving positioning shaft 24 is fixedly connected... Attached to the outside of the translational platform 211, the synchronous transmission toothed belt 27 is placed below the transmission vertical rack 12, and the synchronous transmission toothed belt 27 meshes with the transmission vertical rack 12. When the filter plate 11 is lowered for installation, it drives the transmission vertical rack 12 and makes it mesh with the synchronous transmission toothed belt 27. The synchronous transmission toothed belt 27 drives the active positioning shaft 24 and synchronously drives the driven tooth 26 for transmission. The driven tooth 26 synchronously drives the connecting ring 212 and causes the rotating deceleration sleeve 22 and the rotating shaft of the annular rotary damper 210 to rotate. At this time, the rotating shaft of the annular rotary damper 210 generates damping torque, thereby slowing down the falling speed of the filter plate 11 and improving the stability of the filter plate 11 during installation. The rotating deceleration sleeve 22 is designed in annular shape.The outer surface of the rotating slow-moving sleeve 22 has several locking slots 29 identical to those inside. A protective shell 28 is provided outside the locking slots 29. The protective shell 28 is movably fitted around the driven tooth 26 and is fixedly connected to the outside of the translational base 211 by a reinforcing beam. The side of the protective shell 28 closest to the driving tooth 23 is open, so as not to affect the meshing transmission between the synchronous transmission belt 27 and the transmission vertical rack 12. The lowering speed of the transmission vertical rack 12 can be manually assisted by gripping the locking slots 29.

[0025] After removing the old filter plate 11, the new filter plate 11 to be replaced is hoisted to the top of the corresponding mounting slot 18 using hoisting equipment. Then, the translation platform 211 is pushed to slide horizontally along the extension direction of the transverse groove 21. The translation platform 211 carries the synchronous drive belt 27, the annular rotary damper 210, and other components of the entire slowing mechanism, moving synchronously until the upper tooth surface of the synchronous drive belt 27 is precisely aligned with the position directly below the transmission vertical rack 12 on the side of the filter plate 11. After alignment, the hoisting equipment is controlled to slowly lower the filter plate 11, allowing it to pass through the mounting slot 18 from top to bottom and enter the exhaust gas treatment chamber 10. During this lowering process, the teeth of the transmission vertical rack 12 gradually engage with the upper tooth surface of the synchronous drive belt 27. As the filter plate 11 continues to fall, the transmission vertical rack 12 drives the synchronous drive belt 27 to circulate along the transmission loop formed by the driving tooth 23 and the driven tooth 26. The rotating shaft synchronously drives the active gear 23 to rotate around the active positioning shaft 24, and through the toothed belt meshing transmission, causes the driven gear 26 to rotate synchronously around the fixed roller 25. The driven gear 26 further drives the rotating slow-speed sleeve 22 to rotate coaxially through the connecting ring 212, thereby driving the rotating shaft of the annular rotary damper 210 to rotate synchronously. When the rotating shaft of the annular rotary damper 210 rotates, the blades arranged on its outer ring rotate synchronously in the annular cavity filled with silicone oil. The blades force the silicone oil to flow slowly from one side of the oil cavity to the other side through the narrow throttling gap between the outer edge of the blade and the inner wall of the annular cavity. Relying on the viscous resistance of the silicone oil, a continuous and stable damping torque is generated. This damping torque acts in the opposite direction to the transmission vertical rack 12 through the entire transmission chain, offsetting part of the gravity downward force of the filter plate 11, thereby effectively reducing the lowering and installation speed of the filter plate 11, avoiding the impact damage and alignment deviation caused by the filter plate falling too fast, and ensuring that the entire lowering process is stable and controllable.

[0026] like Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9The rotating slowing sleeve 22 is provided with a stop and anti-fall component on its outside. The stop and anti-fall component includes a stop sleeve 30, which is fixedly connected to one end of the translation platform 211 away from the inside of the transverse groove 21. The stop sleeve 30 is sleeved on the outside of the rotating slowing sleeve 22. A gap is left between the stop sleeve 30 and the rotating slowing sleeve 22 for the rotating slowing sleeve 22 to rotate. The upper end of the stop sleeve 30 is provided with a hinge groove 31. The inside of the hinge groove 31 is rotatably connected to a stop pawl 32 by a pin. The lower end of the stop pawl 32 extends and is inserted into the inside of the abutment groove 29. The upper end of the stop pawl 32 is fixedly connected to an operation handle 33 for easy gripping. The side of the outside of the stop sleeve 30 is fixedly connected to a limit plate hinge seat 35. The inside of the limit plate hinge seat 35 is rotatably connected to a pawl limit plate 34, which is U-shaped.

[0027] During the normal lowering and installation of the filter plate 11, the transmission vertical rack 12 drives the rotating slow-moving sleeve 22 to rotate continuously in a counterclockwise direction. The various abutment grooves 29 on the outer ring of the rotating slow-moving sleeve 22 move synchronously with the disc body. When the side wall of the abutment groove 29 sweeps past the lower end of the stop pawl 32 as it rotates counterclockwise, the side wall of the groove generates a lateral thrust on the lower end of the pawl, causing the stop pawl 32 to swing slightly clockwise around the pin in the hinge groove 31. After this... After the pawl 32 rotates past the slot 29 and passes the pawl position, it automatically returns to its original position under its own weight. This cycle allows for unidirectional free rotation of the deceleration disc without obstructing the normal lowering of the filter plate. If abnormal lowering speed, instability of the hoisting equipment, or temporary suspension occurs during operation, the operator only needs to grasp the operating handle 33 and turn it counterclockwise, causing the pawl 32 to deflect clockwise around the pin shaft, thus lowering the lower end of the pawl 32. The pawl fits tightly into the corresponding locking slot 29, and the engagement between the pawl and the slot limits and blocks the counterclockwise rotation of the slow-moving sleeve 22. This, in turn, locks the downward movement of the vertical rack 12 through the entire transmission chain, achieving immediate suspension and anti-fall of the filter plate 11. This effectively avoids equipment damage and safety accidents caused by the filter plate falling. After the stop and lock are completed, the pawl limiting plate 34 can be further rotated towards the hinge slot 31 with the limiting plate hinge seat 35 as the rotation center until the plate body of the pawl limiting plate 34 is completely inserted into the internal space of the hinge slot 31. At this time, the pawl limiting plate 34 is just fitted into the gap between the back of the stop pawl 32 and the inner wall of the hinge slot 31, restricting the clockwise rotation freedom of the stop pawl 32 from the back side, forming a mechanical locking safety, preventing the stop pawl 32 from being loosened by external force vibration or accidental contact, and further improving the reliability of the locking state and the safety of operation.

[0028] like Figure 1 , Figure 2 , Figure 6 and Figure 7The translation platform 211 is provided with a guide assembly on its exterior. The guide assembly includes an upper guide seat 50, which is fixedly connected to the exterior of the translation platform 211 at the end away from the transverse groove 21. The upper guide seat 50 is provided with an alignment guide groove 52 that matches the thickness of the filter plate 11 on the side away from the translation platform 211. A guide platform 51 is fixedly installed on the upper end of the guide platform 51. The guide platform 51 is an inverted trapezoidal platform. The guide platform 51 is provided with a guide groove for guiding the placement of the filter plate 11 inside. The guide groove of the guide platform 51 communicates with the alignment guide groove 52. The upper guide seat 50 and the alignment guide groove 52 are located above the mounting slot 18.

[0029] Before the filter plate 11 is officially lowered and installed, the filter plate 11 is first hoisted by the hoisting equipment and moved to the area directly above the installation slot 18. The operator assists in adjusting the horizontal posture of the filter plate 11 so that the bottom end of the filter plate 11 is initially aligned with the upper opening of the guide platform 51. Then, the filter plate 11 is slowly lowered. Relying on the inverted trapezoidal inner groove structure of the guide platform 51, the bottom end of the filter plate 11 is automatically guided and centered, gradually correcting the filter plate 11 which has a slight deviation in the horizontal direction, so that it falls smoothly into the alignment guide groove 52 inside the upper guide seat 50. The groove width of the alignment guide slot 52 is precisely matched with the thickness of the filter plate 11, which can form a stable vertical limiting constraint on the filter plate, effectively limiting the back-and-forth and left-and-right swaying during the lowering process. At the same time, it can automatically align the transmission vertical racks 12 on both sides of the filter plate with the meshing position of the synchronous transmission toothed belt 27 below, ensuring that the transmission vertical racks 12 and the synchronous transmission toothed belt 27 can accurately and smoothly enter the meshing transmission state, providing a reliable alignment foundation for subsequent slow lowering operations, greatly reducing the difficulty of hoisting and alignment operations, and improving the efficiency of filter plate installation.

[0030] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 10The side frame 20 is externally equipped with a positioning locking assembly, which includes a positioning insert plate 40, a traction slot 42, a vertical slot 44, and several positioning slots 43. The traction slot 42 is located on the outside of the side frame 20 and communicates with the interior of the transverse sliding slot 21. The positioning insert plate 40 is movably connected to the interior of the traction slot 42 and extends into the interior of the transverse sliding slot 21. Several positioning slots 43 are located inside the transverse sliding slot 21. When the translation platform 211 moves the positioning insert plate 40 above the positioning slot 43, the translation platform 211 moves the upper guide seat 50 above the installation slot 18 by inserting the positioning insert plate 40 into the positioning slot 43, thereby guiding the externally replaced filter plate 11 to be quickly positioned. The number of positioning slots 43 corresponds to the number of installation slots 18, and the positions of the positioning slots 43 and installation slots 18 are corresponding. The slot 44 is formed outside the horizontal slot 21 and communicates with its interior. The positioning plate 40 is movably connected inside the vertical slot 44. The lower end of the positioning plate 40 is inserted into the interior of the positioning slot 43. The upper end of the positioning plate 40 is fixedly installed with a lifting ring 41 for easy gripping. The interior of the positioning plate 40 has a spring mounting cavity 48. The interior of the spring mounting cavity 48 is movably connected with a partition 46. The partition 46 is fixedly connected inside the vertical slot 44. The interior of the partition 46 is movably connected with a guide rod 45. The guide rod 45 is vertically fixed inside the spring mounting cavity 48. The exterior of the guide rod 45 is movably fitted with a return spring 47. The two ends of the return spring 47 are respectively fixedly connected to the side of the partition 46 and the inner wall of the spring mounting cavity 48 facing each other. The return spring 47 applies a pre-tightening force to the positioning plate 40 and the partition 46, so that the positioning plate 40 continues to provide power downward in the initial state.

[0031] After removing the filter plate 11 that needs to be replaced from inside the exhaust gas treatment box 10, the operator horizontally pushes the translation platform 211 along the extension direction of the transverse sliding slot 21, allowing it to slide smoothly along the T-shaped channel and switch to the position directly above the mounting slot 18 corresponding to the filter plate to be installed. During the sliding process of the translation platform 211, the positioning plate 40 moves synchronously with the platform, and its lower end slides along the top surface of the inner wall of the transverse sliding slot 21. When the translation platform 211 moves to the position precisely aligned with the target mounting slot 18, the positioning plate 40 moves exactly above the corresponding positioning slot 43. At this time, the return spring 47 releases its elastic potential energy. The positioning plate 40 is pushed vertically downwards and popped out, so that the lower end of the positioning plate 40 is inserted into the interior of the positioning slot 43. The horizontal position of the translation table 211 is locked by the pin groove, which prevents the translation table 211 from shifting during operation. Through this locking structure, the upper guide seat 50 and the guide table 51 are always accurately aligned above the installation slot 18, ensuring the accuracy of the filter plate insertion and alignment. At the same time, it ensures that the synchronous transmission toothed belt 27 and the transmission vertical rack 12 during the lowering process always maintain a stable and accurate meshing transmission state, providing a stable position reference for the slow installation of the filter plate and the fall protection.

[0032] Working principle: Step 1: Open the top cover and remove the old filter plate: Operators operate the hoisting equipment and, with manual support, hold the top beam plate 15, causing the top cover plate 17 to be vertically lifted along the installation slot 18. The end of the top beam plate 15 slides upward along the vertical section of the hanging slot 14 of the hanging beam plate 13 until it abuts against the inner wall of the slot top. Then, the top beam plate 15 is pushed horizontally, causing the top cover plate 17 to be moved and inserted into the lower horizontal slot of the hanging beam plate 13 until it is completely removed from directly above the installation slot 18, exposing the vertical disassembly and assembly channel. Finally, the filter plate 11 is lifted vertically from the exhaust gas treatment box 10 by hooking the upper lifting lug slot of the external hoisting equipment.

[0033] Step 2: Position and lock the translation seat: After the old filter plate is removed, the translation platform 211 is pushed to slide horizontally along the transverse sliding slot 21 of the side frame 20, driving the entire slow mechanism to move synchronously to the target installation slot 18. When the translation platform 211 is aligned, the return spring 47 drives the positioning insert 40 to be inserted downward into the corresponding positioning slot 43, locking the transverse position of the translation platform 211, so that the upper guide seat 50, the guide table 51 and the installation slot 18 are precisely aligned, while ensuring that the meshing position of the synchronous transmission toothed belt 27 and the transmission vertical rack 12 is precisely aligned.

[0034] Step 3: Lowering the new filter plate with damping: The new filter plate 11 is hoisted above the mounting slot 18. After being automatically guided by the inverted trapezoidal inner groove of the guide table 51, it falls into the alignment guide slot 52 of the upper guide seat 50 to complete the vertical limit. Then, the filter plate is slowly lowered. The transmission vertical rack 12 and the synchronous transmission toothed belt 27 engage, driving the active tooth 23 to rotate synchronously around the active positioning shaft 24 and the driven tooth 26 around the fixed roller 25. Through the connecting ring 212, the rotating slow-speed sleeve 22 and the rotating shaft of the annular rotary damper 210 rotate coaxially. The blades inside the annular rotary damper 210 agitate the silicone oil to generate damping torque, which counteracts the downward force of the filter plate through the transmission chain, smoothly reducing the lowering speed and avoiding damage to the filter plate.

[0035] Step 4, One-way stop and fall arrest protection: When the filter plate is lowered normally, rotate the slow-moving sleeve 22 counterclockwise to push open the lower end of the stop pawl 32 in sequence against the groove 29, so that the stop pawl swings back and forth around the inner pin of the hinge groove 31 without obstructing the normal lowering operation. When temporary suspension or emergency braking is required, turn the operating handle 33 to make the stop pawl 32 engage with the groove 29, lock the slow-moving sleeve 22 to stop the filter plate from descending; then flip the pawl limiting plate 34 around the limiting plate hinge seat 35 and engage it with the hinge groove 31, pressing against the back of the stop pawl 32 to form a mechanical safety, preventing the stop pawl 32 from loosening due to vibration and improving operational safety.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
