Description

Technical Field

[0001] This invention relates to the field of carbon disulfide preparation technology, and in particular to a movable redistribution mechanism and a carbon disulfide distillation column containing the mechanism. Background Technology

[0002] In distillation separation processes, the distillation column is the core equipment, and its operational stability directly determines product purity and production efficiency. To address the problem of uneven liquid distribution and flow along the column wall, which leads to a decrease in gas-liquid mass transfer efficiency, liquid redistribution structures can be installed inside or outside the distillation column in industrial production. Among them, the liquid redistribution structure installed outside the distillation column is called an "external redistributor." This structure receives the liquid flowing out from the upper section of the distillation column, buffers, filters, and homogenizes it, and then redistributes it back to the lower section of the distillation column, achieving efficient liquid redistribution and ensuring the continuity and stability of the distillation process.

[0003] Currently, most existing external redistribution structures adopt the traditional combination of "fixed inclined guide plate + filter plate". The core working principle is as follows: the liquid to be treated flowing out of the upper section of the distillation column (such as sulfur-containing slag liquid in the carbon disulfide distillation process) is transported to the external redistributor cavity through pipelines. It is guided and buffered by the guide plate with a fixed inclined angle to dissipate the kinetic energy of the liquid falling. Then the liquid slides down the inclined surface of the guide plate and drips onto the surface of the filter plate below. The filter plate intercepts solid impurities (such as sulfur slag) in the liquid. After filtration, the filtrate flows into the collection chamber and is then transported back to the distillation column.

[0004] However, the above design has certain limitations, such as extremely uneven liquid distribution and very low effective utilization of the filter plates. The filter plates of the external redistributor are usually arranged along the length of the horizontal cavity, while the guide plates in the traditional structure adopt a fixed tilt angle design. Once the tilt direction and angle are fixed, they cannot be dynamically adjusted according to the filter plate layout and liquid flow rate. When the liquid slides down the fixed tilt guide plate, it will always concentrate and drip onto a specific small area of ​​the filter plate (mostly a local area near the end of the guide plate) due to gravity and guiding effect, forming a phenomenon of "local overflow and overall idleness". Due to the compact cavity space of the external redistributor and the limited size of the filter plates, this concentrated liquid distribution means that most areas of the filter plate cannot contact the liquid, resulting in insufficient utilization of the effective filtration area and waste of filter plate resources. Secondly, the concentrated dripping liquid continuously scours the local area of ​​the filter plate, and the dirt-holding load of this area far exceeds the filter plate design threshold, causing impurities (such as sulfur slag) to accumulate rapidly in this area, which in turn causes local blockage of the filter plate. Blockage not only increases the resistance to liquid flow and the energy consumption of transportation, but also requires frequent shutdowns to disassemble the redistributor cavity outside the tower, clean or replace the filter plates, which seriously affects the continuity of the distillation process. Summary of the Invention

[0005] Therefore, it is necessary to provide a movable redistribution mechanism that can improve filtration efficiency and a carbon disulfide distillation column containing the above-mentioned technical problems.

[0006] The present invention provides a movable redistribution mechanism, comprising a distributor and an inlet pipe that penetrates and is installed on one side of the distributor, and further comprising: An anti-impact plate is obliquely and fixedly installed inside the distributor, located on the opposite side of the inlet pipe; The filter plate is detachably installed inside the distributor, located below the anti-impact plate; The liquid outlet pipe is installed through one side of the distributor, located below the filter plate; A liquid receiving frame is movably disposed inside the distributor, located between the anti-impact plate and the filter plate; A drive component, located within the distributor, is used to drive the liquid receiving frame to move laterally and reciprocally.

[0007] In one embodiment, the drive assembly includes a fixed frame, which is fixedly installed on the inner wall of one side of the distributor. A sliding block is slidably installed inside the fixed frame, and one side of the sliding block is fixedly connected to one side of the liquid receiving frame via a connecting bracket.

[0008] In one embodiment, rotating rods are axially symmetrically mounted on both sides of the fixed frame. One end of the rotating rod movably passes through the side wall of the liquid receiving frame, and the other end is fixedly mounted with a drive gear. Chains are driven to the outer sides of the two drive gears. An oblong hole is opened in the middle of the sliding block, and a movable rod is movably embedded in the oblong hole. A connecting plate is movably connected to the outer side of one end of the movable rod, and the end of the connecting plate away from the movable rod is driven to the chain.

[0009] In one embodiment, a drain plate is detachably installed inside the liquid receiving frame, and a baffle is movably abutted against the bottom of the liquid receiving frame, with the baffle located below the drain plate.

[0010] In one embodiment, fixed plates are axially symmetrically fixed at both ends of the bottom of the liquid receiving frame, and a rotating cylinder is rotatably installed between the two fixed plates. One end of the rotating cylinder movably passes through one of the fixed plates, which is away from the fixed frame. One end of the baffle is fixedly sleeved on the outside of the rotating cylinder.

[0011] In one embodiment, a swing plate is fixedly sleeved on the outer side of the rotating cylinder away from the fixed frame. A swing groove is opened in the middle of the swing plate. A rotating disk is movably arranged on one side of the swing plate. A crossbar is fixedly arranged on the rotating disk near the swing plate. The end of the crossbar away from the rotating disk is slidably attached to the swing groove.

[0012] In one embodiment, a transverse groove is formed on the inner wall of the distributor at the end away from the fixed frame, and a positioning frame is fixedly provided at the end of the liquid receiving frame near the transverse groove. The positioning frame is slidably connected to the transverse groove, and a rotating shaft is rotatably installed at the end of the positioning frame near the rotating disk. The end of the rotating shaft away from the positioning frame is fixedly connected to the rotating disk.

[0013] In one embodiment, a rotating gear is movably engaged on the outer side of the middle part of the rotating shaft, and a rack is fixedly disposed in the transverse groove, wherein the rotating gear meshes with the rack for transmission.

[0014] In one embodiment, a fixing ring is fixedly provided on one side of the rotating gear, and a plurality of sawtooth grooves are formed in an annular array on the inner side of the fixing ring. A sawtooth block is movably engaged in the sawtooth groove, and the bottom of the sawtooth block is fixedly connected to the rotating shaft by a positioning spring.

[0015] In one embodiment, the baffle is hollow inside, and multiple vertical rods are rotatably mounted in a horizontal linear array at the end of the baffle. A portion of the vertical rod is located inside the baffle, and a movable plate is fixedly sleeved on the outer side of this portion. The bottom of the movable plate is fixedly connected to the inner wall of the baffle by a torsion spring, and a rotating plate is fixedly sleeved on the outer side of the portion of the vertical rod located outside the baffle.

[0016] In one embodiment, a fixed rod is movably disposed inside the rotating cylinder. One end of the fixed rod is fixedly connected to the fixed plate near the fixed frame. Multiple cams are fixedly sleeved on the outside of the fixed rod in a horizontal linear array. Multiple movable rods are movably disposed through the rotating cylinder in a horizontal linear array. One end of the movable rod is slidably embedded in the surface of the cam, and the other end of the movable rod is movably abutting against the movable plate.

[0017] In one embodiment, a carbon disulfide distillation column includes the aforementioned movable redistribution mechanism.

[0018] The aforementioned movable redistribution mechanism and carbon disulfide distillation column containing this mechanism, through a drive assembly driving the liquid receiving frame to reciprocate, achieve uniform liquid distribution onto the filter plate surface, thus improving the liquid filtration effect; during the rotation of the rotating cylinder, the cooperation of the swing plate, swing groove, rotating disk, and crossbar drives the baffle to perform a smooth reciprocating swing, causing the baffle to open and close alternately. Combined with the lateral reciprocating movement of the liquid receiving frame, this prevents the liquid from continuously flowing out in streams, effectively solving the problem of concentrated liquid distribution caused by the single opening and closing of traditional baffles, ensuring that the liquid can uniformly cover the entire surface of the filter plate. The surface provides a stable foundation for subsequent filtration and distillation. Relying on the precise cooperation between the cam and the moving rod, one end of the moving rod is tightly slidably embedded in the cam surface through a roller or arc groove, without disengagement or jamming, and achieves stable lateral movement with the change of the cam profile. The other end abuts against the movable plate through a rounded corner, reducing friction loss and accurately transmitting power, driving the vertical rod and the rotating plate to rotate synchronously. With the reset action of the torsion spring, the rotating plate reciprocates, continuously agitating the water flow flowing down the baffle, breaking the stream of water into fine droplets, and avoiding liquid deviation and accumulation.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] The following is combined Figures 1-12 The present invention describes a movable redistribution mechanism and a carbon disulfide distillation column containing the mechanism.

[0028] like Figures 1-6 As shown, in one embodiment, a movable redistribution mechanism includes a distributor 1 and an inlet pipe 2 that extends through and is installed on one side of the distributor 1, and further includes: Anti-impact plate 3 is installed at an angle inside distributor 1, located on the opposite side of inlet pipe 2; Filter plate 4 is detachably installed inside distributor 1, located below anti-impact plate 3; The liquid outlet pipe 5 is installed through one side of the distributor 1, located below the filter plate 4; The liquid receiving frame 6 is movably installed inside the distributor 1, located between the anti-impact plate 3 and the filter plate 4; The drive component 7, located inside the distributor 1, is used to drive the liquid receiving frame 6 to move laterally back and forth.

[0029] Specifically, one end of the inlet pipe 2 is connected to the outlet pipe 5 of the upper section of the crude distillation column, used to introduce the liquid to be treated in the crude distillation column into the distributor 1. The other end of the inlet pipe 2 extends into the cavity of the distributor 1, and the outlet faces the other side of the distributor 1 to ensure that the liquid can enter the distributor 1 smoothly and avoid direct impact on the inner wall of the distributor 1. The anti-impact plate 3 is fixedly installed inside the distributor 1 in an inclined state and is located on the opposite side of the inlet pipe 2. The inclination angle of the anti-impact plate 3 is adapted to the outlet direction of the inlet pipe 2, used to receive the liquid flowing out of the inlet pipe 2, playing a buffering and energy dissipation role, dissipating the kinetic energy when the liquid flows out, and guiding the liquid to slide smoothly down the inclined surface of the anti-impact plate 3, providing a stable liquid flow guide for the subsequent liquid receiving frame 6 to receive the liquid. The distributor 1 is also equipped with a filter plate 4, which is detachably installed inside the distributor 1 and located below the anti-impact plate 3. The filter plate 4 is used to intercept solid impurities (such as sulfur slag) in the liquid to be treated, realizing the filtration and purification of the liquid. The liquid receiving frame 6 The active device is located inside the distributor 1, between the anti-impact plate 3 and the filter plate 4. The width of the liquid receiving frame 6 is adapted to the width of the filter plate 4, and the length is adapted to the horizontal cavity layout of the distributor 1. It can accurately receive the liquid flowing down from the anti-impact plate 3, and at the same time cover the entire length of the filter plate 4, ensuring that the liquid can be evenly sprinkled to each area of ​​the filter plate 4. The drive component 7 is used to drive the liquid receiving frame 6 to move laterally back and forth, so as to achieve the even sprinkling of liquid on the surface of the filter plate 4. In this application, the distributor 1 is located between the crude distillation column and the rectification column, and is located outside the column. The liquid carbon disulfide in the crude distillation column enters the interior of the distributor 1 through the liquid inlet pipe 2. The distributor 1 is equipped with a condensation device, which recirculates a portion of the condensed liquid carbon disulfide back into the crude distillation column for cooling and washing residual sulfur. The other portion of the liquid filtered by the filter plate 4 is connected to the feed pipe of the lower section of the rectification column through the liquid outlet pipe 5 and flows into the rectification column, realizing the recycling of the filtered liquid and ensuring the continuity of the rectification process.

[0030] See Figures 2-4 and Figure 6 As shown, in this embodiment, the drive component 7 includes a fixed frame 71, which is fixedly installed on the inner wall of one side of the distributor 1. A sliding block 72 is slidably installed inside the fixed frame 71, and one side of the sliding block 72 is fixedly connected to one side of the liquid receiving frame 6 through a connecting bracket 79.

[0031] Specifically, the fixing frame 71 is fixedly installed on the inner wall of one side of the distributor 1. The installation direction of the fixing frame 71 is consistent with the moving direction of the liquid receiving frame 6, fitting the horizontal cavity structure of the distributor 1. The fixing frame 71 adopts a structural design adapted to the inner wall of the distributor 1 and is fixed by welding to ensure a firm installation without loosening. At the same time, it does not occupy too much space inside the distributor 1 and does not affect the liquid flow or the normal operation of other components. The sliding block 72 is tightly fitted to the inner wall of the fixing frame 71 and can slide smoothly along the length of the fixing frame 71 without deviation or jamming. The inner wall of the fixed frame 71 is polished and fitted with a PTFE wear-resistant bushing to reduce frictional loss between the sliding block 72 and the fixed frame 71, extend the service life of the drive assembly 7, and ensure that the sliding block 72 slides smoothly, driving the liquid receiving frame 6 to move steadily. One side of the sliding block 72 is fixedly connected to one side of the liquid receiving frame 6 through the connecting bracket 79. The connecting bracket 79 adopts a rigid structure and is fixed to both the sliding block 72 and the liquid receiving frame 6 with bolts, ensuring a firm connection and accurately transmitting the sliding motion of the sliding block 72 to the liquid receiving frame 6, ensuring that the sliding block 72 and the liquid receiving frame 6 move synchronously.

[0032] See Figures 2-4 and Figure 6 As shown, in this embodiment, rotating rods 73 are axially symmetrically mounted on both sides of the fixed frame 71. One end of the rotating rod 73 movably passes through the side wall of the liquid receiving frame 6, and the other end is fixedly mounted with a drive gear 74. The two drive gears 74 are connected to the outer sides of the drive gears 74 by a chain 75. The middle of the sliding block 72 is provided with an oblong hole 76. A movable rod 77 is movably embedded in the oblong hole 76. A connecting plate 78 is movably connected to the outer side of one end of the movable rod 77. The end of the connecting plate 78 away from the movable rod 77 is connected to the chain 75 by a drive.

[0033] Specifically, the rotating rod 73 and the fixed frame 71 are hinged with bearings to ensure that the rotating rod 73 can rotate flexibly without jamming. The installation direction of the rotating rod 73 is consistent with the length direction of the fixed frame 71, that is, parallel to the moving direction of the liquid receiving frame 6. One end of the rotating rod 73 movably passes through the side wall of the liquid receiving frame 6, and the penetration is sealed with a PTFE wear-resistant bushing. This ensures that the rotating rod 73 can rotate smoothly and prevents the liquid in the liquid receiving frame 6 from leaking out of the penetration, which meets the requirements of the sealed process. The other end of the rotating rod 73 is fixedly installed with a drive gear 74. The drive gear 74 is coaxial with the rotating rod 73 to ensure that the rotating rod 73 can drive the drive gear 74 to rotate synchronously. The two drive gears 74 are symmetrically arranged on both sides of the fixed frame 71. The outer drive is connected by a chain 75, which precisely meshes with the two drive gears 74 to achieve... Synchronous transmission ensures that the rotating rods 73 on both sides can rotate synchronously, thereby ensuring that the liquid receiving frame 6 is subjected to uniform force and without deviation when moving. The sliding block 72 has an oblong hole 76 in the middle, and the length direction of the oblong hole 76 is consistent with the sliding direction of the sliding block 72. A movable rod 77 is movably embedded in the oblong hole 76. The movable rod 77 can slide and rotate flexibly in the oblong hole 76, providing buffer and adjustment space for subsequent transmission actions and avoiding jamming during transmission. A connecting plate 78 is movably connected to the outer side of one end of the movable rod 77. The connecting plate 78 and the movable rod 77 are connected by a hinge. The connecting plate 78 is designed to allow for flexible angle adjustment as the movable rod 77 moves and rotates. The end of the connecting plate 78 furthest from the movable rod 77 is connected to the chain 75, ensuring a secure and relatively movable connection. This allows for precise transmission of the chain 75's motion to the movable rod 77, which in turn drives the sliding block 72 to slide. Crucially, the structural design of the chain 75, movable rod 77, and connecting plate 78 enables the liquid receiving frame 6 to pause briefly: when the chain 75 drives the connecting plate 78 to the positions of the drive gears 74 on both sides, the connecting plate 78 rotates with the chain 75 to the side of the drive gears 74. When the connecting plate 78 moves up and down relative to the drive gear 74, this movement is transmitted to the movable rod 77 through the hinge point. The movable rod 77 moves up and down in the oval hole 76 of the sliding block 72 without causing the sliding block 72 to slide along the fixed frame 71. This allows the liquid receiving frame 6, which is fixedly connected to the sliding block 72 through the connecting bracket 79, to pause briefly. This pause ensures that the liquid receiving frame 6 catches more liquid flowing down along the anti-surge plate 3, preventing liquid leakage due to the rapid movement of the liquid receiving frame 6. This improves the sufficiency of liquid reception and the uniformity of liquid distribution, further optimizing the filtration effect.

[0034] See Figures 2-4 As shown, in this embodiment, a drain plate 8 is detachably installed inside the liquid receiving frame 6, and a baffle 9 is movably abutted against the bottom of the liquid receiving frame 6, with the baffle 9 located below the drain plate 8.

[0035] Specifically, the liquid receiving frame 6 is made of lightweight and corrosion-resistant material, suitable for use with corrosive media such as carbon disulfide. Inside, a detachable strainer plate 8 is installed. The strainer plate 8 has an array of liquid distribution holes, which are used to evenly disperse the liquid in the liquid receiving frame 6 and spray it out, so as to achieve the initial homogenization of the liquid and facilitate the subsequent even distribution of the liquid to the surface of the filter plate 4. The strainer plate 8 is detachable, which makes it easy to clean the sulfur slag and other impurities attached to the strainer plate 8, avoids the blockage of the liquid distribution holes, and eliminates the need to disassemble the entire liquid receiving frame 6, thus reducing the difficulty of maintenance. A baffle 9 is movably abutted at the bottom of the liquid receiving frame 6. The baffle 9 is located below the filter plate 8 and is tightly abutted against the bottom of the liquid receiving frame 6 to provide a seal. It is used to control the liquid receiving and distribution actions of the liquid receiving frame 6. When receiving liquid, the baffle 9 remains abutted to ensure that the liquid does not leak from the bottom of the liquid receiving frame 6 and can fully store the liquid received by the liquid receiving frame 6. When distributing liquid, the baffle 9 is dismounted from the bottom of the liquid receiving frame 6, and the liquid distribution holes on the filter plate 8 are exposed. The liquid is evenly sprayed onto the surface of the filter plate 4 through the liquid distribution holes to achieve uniform liquid distribution.

[0036] See Figure 4 , Figure 5 and Figure 10 As shown, in this embodiment, fixed plates 10 are axially symmetrically fixed at both ends of the bottom of the liquid receiving frame 6, and a rotating cylinder 11 is rotatably installed between the two fixed plates 10. One end of the rotating cylinder 11 movably passes through one of the fixed plates 10, and the fixed plate 10 is away from the fixed frame 71. One end of the baffle 9 is fixedly sleeved on the outside of the rotating cylinder 11.

[0037] Specifically, the fixing plate 10 is integrally formed or bolted to the bottom of the liquid receiving frame 6 to ensure a firm and secure installation. The two fixing plates 10 are symmetrically arranged to match the length of the liquid receiving frame 6, without affecting the movement of the liquid receiving frame 6 or the receiving and distribution of liquid. A rotating cylinder 11 is rotatably installed between the two fixing plates 10. The installation direction of the rotating cylinder 11 is consistent with the length of the liquid receiving frame 6. The rotating cylinder 11 is hinged to the two fixing plates 10 using bearings to ensure that the rotating cylinder 11 can rotate flexibly without jamming and without deviation during rotation, providing a stable rotational foundation for the opening and closing of the baffle 9.

[0038] See Figure 4 , Figure 5 and Figure 8 As shown, in this embodiment, a swing plate 12 is fixedly sleeved on the outer side of the rotating cylinder 11 away from the fixed frame 71. A swing groove 121 is opened in the middle of the swing plate 12. A rotating disk 13 is movably arranged on one side of the swing plate 12. A crossbar 14 is fixedly arranged on the end of the rotating disk 13 close to the swing plate 12. The end of the crossbar 14 away from the rotating disk 13 slides and fits against the swing groove 121.

[0039] Specifically, the clockwise rotation of the rotating disk 13 drives the crossbar 14 to rotate. During the rotation of the crossbar 14, it moves back and forth relative to the swing groove 121, which drives the swing plate 12 to swing back and forth. This causes the rotating cylinder 11 and the baffle 9 to swing back and forth. The baffle 9 swings back and forth with the rotating cylinder 11, which can form a periodic opening and closing of the liquid flowing out of the filter plate 8, so that the liquid falls in a pulse and segmented manner, rather than flowing out continuously in a stream. This effectively avoids the liquid concentrating and scouring the local area of ​​the filter plate 4, and allows the liquid to be more evenly distributed along the length of the filter plate 4, which greatly improves the utilization rate of the effective filtration area of ​​the filter plate 4. Secondly, during the reciprocating opening and closing process, the baffle 9 will cut, disturb and disperse the falling liquid flow, breaking the originally streamed liquid into smaller droplets or liquid films, increasing the contact area between the liquid and the filter plate 4, prolonging the residence time of the liquid on the surface of the filter plate 4, making it easier to trap impurities, and significantly improving the filtration accuracy and filtration efficiency.

[0040] See Figures 3-7 As shown, in this embodiment, a transverse groove 101 is provided on the inner wall of the distributor 1 at the end away from the fixed frame 71. A positioning frame 15 is fixedly provided on the liquid receiving frame 6 at the end near the transverse groove 101. The positioning frame 15 is slidably connected to the transverse groove 101. A rotating shaft 16 is rotatably installed on the end of the positioning frame 15 near the rotating disk 13. The end of the rotating shaft 16 away from the positioning frame 15 is fixedly connected to the rotating disk 13.

[0041] Specifically, during the movement of the liquid receiving frame 6, the positioning frame 15 will move along the transverse groove 101. During this process, the rotation of the rotating shaft 16 will drive the rotating disk 13 to rotate synchronously, so that the baffle 9 will reciprocate to open and close during the movement of the liquid receiving frame 6.

[0042] See Figure 5 and Figure 7 As shown, in this embodiment, a rotating gear 17 is movably engaged on the outer side of the middle part of the rotating shaft 16, and a rack 18 is fixedly disposed in the transverse groove 101. The rotating gear 17 and the rack 18 mesh and transmit power.

[0043] Specifically, during the movement of the liquid receiving frame 6, the rotating gear 17 will mesh with the rack 18, thereby rotating the rotating gear 17, which in turn drives the rotating shaft 16 to rotate, ultimately opening and closing the baffle 9 and improving the filtration effect.

[0044] See Figure 9 As shown, in this embodiment, a fixing ring 19 is fixedly provided on one side of the rotating gear 17. Multiple sawtooth grooves 191 are formed in an annular array on the inner side of the fixing ring 19. A sawtooth block 20 is movably engaged in the sawtooth groove 191. The bottom of the sawtooth block 20 is fixedly connected to the rotating shaft 16 by a positioning spring 21.

[0045] Specifically, when the opening of the liquid receiving frame 6 is below the anti-impact plate 3, the baffle 9 is in a closed state, capable of catching a large amount of liquid. When the liquid receiving frame 6 moves away from the liquid inlet pipe 2, the rotating gear 17 meshes with the rack 18, causing the rotating gear 17 to rotate clockwise. The fixing ring 19 also rotates clockwise synchronously. During this rotation, the serrated block 20 and the serrated groove 191 are engaged, and the rotating shaft 16 also rotates clockwise synchronously, enabling the rotating disk 13 to rotate. This allows the baffle 9 to alternate during movement. The opening and closing mechanism enhances the filtration effect. When the liquid receiving frame 6 is at its furthest point from the liquid inlet pipe 2, the baffle 9 is in a closed state. At this time, the liquid receiving frame 6 will move in the opposite direction. During this process, the rotating gear 17 will rotate counterclockwise, and the fixing ring 19 will rotate counterclockwise simultaneously. When rotating in this direction, the serrated block 20 will not engage with the serrated groove 191. The serrated block 20 will be pressed downward to compress the positioning spring 21. The rotating shaft 16 will not rotate, that is, the baffle 9 will not open and will remain closed until it moves below the anti-impact plate 3 to facilitate the collection of liquid.

[0046] See Figures 10-12 As shown, in this embodiment, the baffle 9 is hollow inside. Multiple vertical rods 22 are rotatably mounted in a horizontal linear array at the end of the baffle 9. A portion of the vertical rods 22 is located inside the baffle 9, and a movable plate 23 is fixedly sleeved on the outer side of this portion. The bottom of the movable plate 23 is fixedly connected to the inner wall of the baffle 9 by a torsion spring 24. A rotating piece 25 is fixedly sleeved on the outer side of the portion of the vertical rods 22 located outside the baffle 9.

[0047] Specifically, the baffle 9 is hollow inside. The hollow structure can reduce the overall weight of the baffle 9, reduce the load on transmission components such as the rotating cylinder 11 and the swing plate 12, and extend the service life of the transmission components. It can also provide space for the installation of the vertical rod 22, the movable plate 23 and the torsion spring 24, making the overall structure more compact, without occupying extra installation space, and adapting to the limited layout of the liquid receiving frame 6. Multiple vertical rods 22 are rotatably mounted in a horizontal linear array at the end of the baffle 9. The installation direction of the vertical rods 22 is perpendicular to the thickness direction of the baffle 9 and parallel to the length direction of the liquid receiving frame 6. The vertical rods 22 and the baffle 9 are connected by bearings to ensure that the vertical rods 22 can rotate flexibly without jamming. The multiple vertical rods 22 are arranged in a uniform array to fully cover the liquid distribution area at the end of the baffle 9 without any stirring dead corners. A part of the vertical rods 22 is located inside the baffle 9, and a movable plate 23 is fixedly sleeved on the outside of this part. The movable plate 23 and the vertical rods 22 are fixed with an interference fit or bolts to ensure a firm connection. When the vertical rods 22 rotate, they can drive the movable plate 23 to rotate synchronously. The bottom of the movable plate 23 is fixedly connected to the inner wall of the baffle 9 by a torsion spring 24. The torsion spring 24 is sleeved on the outside of the vertical rod 22, and its two ends are fixedly connected to the bottom of the movable plate 23 and the inner wall of the baffle 9, respectively. When the torsion spring 24 is in its natural state, it can provide a stable restoring force for the movable plate 23, thereby driving the vertical rod 22 and the rotating plate 25 to maintain their initial positions, ensuring that the rotating plate 25 will not shake randomly when the baffle 9 is closed, thus affecting the sealing effect. When an external force drives the vertical rod 22 to rotate, the movable plate 23 compresses the torsion spring 24 to produce elastic deformation. After the external force disappears, the restoring force of the torsion spring 24 can drive the movable plate 23, the vertical rod 22 and the rotating plate 25 to quickly return to their original positions, ensuring that the rotating plate 25... The stirring action is stable and controllable. As the baffle 9 swings back and forth with the rotating cylinder 11, and alternately opens or closes, the rotating plate 25 also rotates synchronously. When the baffle 9 is open and the liquid flows down through the filter plate 8 and slides down the surface of the baffle 9, the synchronous rotation of the rotating plate 25 can fully stir the water flow down along the baffle 9, further breaking the stream of water into fine droplets. At the same time, it avoids the liquid from forming a liquid film accumulation or local deviation on the surface of the baffle 9, so that the liquid can be more evenly sprinkled from the end of the baffle 9 onto the surface of the filter plate 4, further improving the uniformity of liquid distribution. At the same time, the stirring action can also reduce the adhesion of impurities such as sulfur slag on the surface of the baffle 9, playing an auxiliary role in preventing blockage.

[0048] See Figures 10-12 As shown, in this embodiment, a fixed rod 26 is movably arranged inside the rotating cylinder 11. One end of the fixed rod 26 is fixedly connected to the fixed plate 10 near the fixed frame 71. Multiple cams 27 are fixedly sleeved on the outer side of the fixed rod 26 in a horizontal linear array. Multiple moving rods 28 are movably arranged in a horizontal linear array on the rotating cylinder 11. One end of the moving rod 28 is slidably embedded in the surface of the cam 27, and the other end of the moving rod 28 is movably abutting against the movable plate 23.

[0049] Specifically, one end of the moving rod 28 is slidably embedded in the surface of the cam 27. This end of the moving rod 28 can be provided with a roller or arc-shaped groove that matches the contour of the cam 27, ensuring that the moving rod 28 can slide closely against the surface of the cam 27 without disengagement or jamming, and can move laterally as the contour of the cam 27 changes. The other end of the moving rod 28 is movably abutted against the movable plate 23. The abutment point can be provided with rounded corners to reduce friction loss between the moving rod 28 and the movable plate 23, ensuring that the moving rod 28 can accurately push the movable plate 23 to rotate when it moves laterally, thereby driving the vertical rod 22 and the rotating plate 25 to rotate synchronously. During the rotation of the rotating cylinder 11, the moving rod 28 is driven to rotate synchronously around the fixed rod 26. One end of the moving rod 28 slides relative to the surface of the cam 27. Since the profile of the cam 27 is not circular, as the rotation angle changes, the cam 27 will push the moving rod 28 to reciprocate laterally along its own axis. When the moving rod 28 moves laterally, it pushes the movable plate 23 to rotate around the axis of the vertical rod 22. The movable plate 23 compresses the torsion spring 24 to produce elastic deformation. When the moving rod 28 moves in the opposite direction, the restoring force of the torsion spring 24 drives the movable plate 23, the vertical rod 22 and the rotating plate 25 to rotate in the opposite direction, realizing the reciprocating rotation of the vertical rod 22 and the rotating plate 25, thereby driving the rotating plate 25 to continuously agitate the water flow.
