Description

Technical Field

[0001] The invention relates to the technical field of petrochemical pipelines, and in particular to a manifold with a self-cleaning function and a cleaning method. Background Art

[0002] Catalytic cracking units have always occupied a very large proportion in the field of crude oil processing. Almost every refinery will build one or several catalytic cracking units in the early stage of construction in order to deal with the residual oil left by the atmospheric and vacuum units. These units have created very considerable economic benefits for each refinery. As environmental protection is increasingly on the agenda, the pollution problem of catalytic flue gas has gradually been taken seriously by people. Catalytic flue gas desulfurization has become a unit that must be considered for catalytic units. Among them, wet flue gas desulfurization is a common method of catalytic flue gas desulfurization. Its main principle is to introduce flue gas into the scrubber, and fully react with the bottom fluid in the mixer before entering the tower. The mixed liquid after the reaction enters the scrubber for gas-liquid separation, and the purified flue gas is discharged into the atmosphere. The bottom fluid can be pumped back to the mixer for recycling. In order to make the reaction more complete and the layout more reasonable, the catalytic flue gas is generally fed into the scrubbing tower in two symmetrical streams, so the bottom fluid must also be fed into the mixer in two ways. Under normal operating conditions, only one bottom pump works. Therefore, the process requires special treatment of the fluid before it enters the mixer, so that the amount of fluid entering the two mixers is roughly the same, the distribution is more even, and the deviation is avoided, so that the equipment runs more smoothly.

[0003] The patent with publication number CN217784533U discloses a liquid pipeline distribution manifold, including a coil arranged around a washing tower, wherein the coil is formed by a first coil and a second coil fixedly connected; an inlet nipple is arranged at the bottom of the coil, and two outlet nipples are arranged at the top, wherein the caliber of the inlet nipple is equal to the caliber of the coil, and the caliber of the outlet nipple is smaller than the caliber of the coil, wherein one outlet nipple is located on the first coil, and the other outlet nipple is located on the second coil, and the two outlet nipples are arranged symmetrically about the inlet nipple; and a plurality of brackets are arranged circumferentially at the bottom of the coil. However, the scheme still has the following problems: the manifold is an annular structure with a large internal volume, and the circulating liquid must first fill the manifold before it can flow out, and the initial response is slow, and at the same time, scale is prone to appear inside the annular manifold after long-term use, which is inconvenient to clean.

[0004] Therefore, it is urgent to design a new manifold and control method to solve the problems in the prior art of large internal volume, slow initial response, easy formation of scale inside the annular manifold after long-term use, and inconvenient cleaning. Summary of the invention

[0008] Furthermore, an arc-shaped vertical plate is provided on the inner side of the scraper blade, and one end of the scraper blade away from the inner wall of the first circle tube is connected to the vertical plate to form a storage bin with an annular structure.

[0009] Furthermore, an elastic sealing portion is provided at one end of the vertical plate away from the connection end with the scraper blade, the length of the vertical plate is greater than the length of the scraper blade, and the scraper blade, the vertical plate, the inner wall of the first circle tube, and the sealing plate can form a closed space.

[0010] Furthermore, the cross-sections of the plurality of support rods distributed along the radial direction of the central rod are streamlined, and the angles between the support rods and the central rod are acute, and the size of the angle is 80°-90°.

DETAILED DESCRIPTION

[0021] In order to make the technical means, objectives and effects of the present invention easy to understand, the embodiments of the present invention are described in detail below with reference to specific drawings.

[0022] It should be noted that all the terms used in the present invention to indicate directionality and positionality, such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", "top", "lower", "lateral", "longitudinal", "center", etc., are only used to explain the relative positional relationship and connection status between the components in a certain state, and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention discloses a manifold with a self-cleaning function, comprising a first coil tube 1, a second coil tube 2, an inlet tube 3, a first outlet tube 4, a second outlet tube 5, a cleaning assembly 6, a driving assembly 7 and a bracket 8; The first circle tube 1 and the second circle tube 2 are both semi-annular tubes, the tube opening cross section of the first circle tube 1 is circular, and the tube opening cross section of the second circle tube 2 is arched, and sealing plates 10 are provided at the tube openings at both ends of the first circle tube 1, and a notch 11 is provided on the sealing plate 10, and the second circle tube 2 is connected to the notch 11 of the first circle tube 1, and after the two are connected, they can be docked in the same plane to form an annular, continuous fluid channel, by connecting the second circle tube 2 to the notch 11 of the first circle tube 1, the fluid can enter the second circle tube 2 from the inside of the first circle tube 1 through the notch 11, ensuring the circulation of the fluid in the entire system, and can give full play to the equal distribution effect of the communicating vessel, while greatly reducing the internal volume of the manifold, shortening the initial reaction time of the manifold distributing the fluid, and improving the response speed, the aforementioned formed fluid channel surrounds the outer wall of the washing tower 9, the nominal diameter of the washing tower 9 is DN3000, and the nominal diameters of the first circle tube 1 and the second circle tube 2 are DN600; The nominal diameter of the inlet pipe 3 is DN600. The inlet pipe 3 is connected to the side of the first coil 1 and is used for the fluid to flow into the manifold. The inlet pipe 3 is arranged along the radial direction of the first coil 1. The inlet pipe 3 is a curved pipe. The impact force of the fluid on the first coil 1 is reduced radially, which reduces the turbulence effect generated when the fluid enters, reduces energy loss, and improves the stability of the fluid flow. At the same time, the manifold transmits the force to the washing tower 9 or evenly disperses it, avoiding the problem that the first coil 1 is deformed due to the unilateral axial force in the existing connection structure and the bracket 8 is prone to loosening, which helps to reduce energy loss and improve the stability and reliability of the structure; The nominal diameter of the first outlet pipe 4 and the second outlet pipe 5 is DN450. The first outlet pipe 4 and the second outlet pipe 5 are axially arranged at the top of the first circle pipe 1. The first outlet pipe 4 and the second outlet pipe 5 are symmetrically arranged about the inlet pipe 3. The first outlet pipe 4 and the second outlet pipe 5 are arranged adjacent to the second circle pipe 2, which can better play the role of the communicating vessel, ensure that the flow rate of the fluid flowing out of the two outlet pipes is more uniform, reduce the flow unevenness caused by position differences, and improve the stability and efficiency of the system. At the same time, there is a smooth transition between the first outlet pipe 4 and the first circle pipe 1, and between the second outlet pipe 5 and the first circle pipe 1. The inner wall arc of the transition section is denoted as R 内 , the outer wall arc of the transition section is R 外 , then R 内 <R 外 , so that when the fluid enters the first outlet pipe 4 or the second outlet pipe 5 from the first coil pipe 1, it can flow along a smoother path, reducing the turbulence caused by sudden changes in direction or speed, which can not only reduce energy loss, but also improve the overall efficiency of the system, and the inner and outer wall arcs R of the transition section 内 <R 外 , so that the transition section forms a structure that is thick in the middle and thin on both sides, so that the transition section can better withstand fluid impact and wear and extend its service life.

[0026] like Figure 3 , Figure 7 , Figure 8As shown, the cleaning assembly 6 is arranged inside the first circle tube 1, and the two groups of cleaning assemblies 6 are symmetrically arranged about the inlet tube 3. The cleaning assembly 6 is used to clean the scale on the inner wall of the manifold, so that the cleaning process can be carried out without interrupting the flow of fluid, thereby improving the reliability and efficiency of the system. At the same time, the driving assembly 7 can be used to clean the scale on the inner wall of the annular first circle tube 1, thereby reducing the need for manual maintenance and ensuring the thoroughness and consistency of cleaning. The built-in cleaning assembly 6 and the driving system effectively solve the problem that the annular manifold system is prone to performance degradation and increased maintenance costs due to the accumulation of scale and other deposits, thereby realizing an automated cleaning process, reducing manual intervention, and improving the operating efficiency and reliability of the system. The entire system layout is more compact, saving installation space, and is easy to integrate into the existing washing tower system. The cleaning assembly 6 includes a scraper blade 601, a support rod 602 and a center rod 603. The scraper blade 601 is an annular structure, which is used to directly contact the inner wall of the first coil 1 to remove scale and other sediments. The center rod 603 is arranged at the center of the scraper blade 601 and is connected to the scraper blade 601 through the support rod 602. At least two support rods 602 are evenly distributed along the circumference of the center rod 603. The annular scraper blade 601 can completely cover the inner wall of the first circle tube 1 to ensure that there is no dead angle in the cleaning. The circumferential uniform distribution design of the support rod 602 makes the scraper blade 601 evenly stressed, avoiding wear or damage caused by local uneven stress. The center rod 603 in the present invention can be arc-shaped and can match the circular cross-section of the first circle tube 1, ensuring that the cleaning component 6 can maintain the correct posture at different positions, enhancing the adaptability of the system. This setting improves the cleaning efficiency, ensures that the cleaning component 6 always stably fits the inner wall during the movement, reduces the jitter and deviation during the cleaning process, and has good reliability and stability. The scraper blade 601 forms an acute angle with the inner wall of the first circle tube 1. The acute angle design enables the scraper blade 601 to form a larger effective contact area when contacting the inner wall of the first circle tube 1, thereby increasing the removal effect of scale and other deposits, making hard deposits easier to remove and improving cleaning efficiency. The acute angle design can reduce turbulence and eddy currents between the scraper blade 601 and the tube wall, optimize the fluid flow path, and reduce resistance within the system.

[0027] like Figure 7 , Figure 8As shown, an arc-shaped vertical plate 604 is provided on the inner side of the scraper blade 601, and one end of the scraper blade 601 away from the inner wall of the first circle tube 1 is connected to the vertical plate 604 to form a storage bin 605 of an annular structure. The storage bin 605 can effectively collect scale or other foreign matter scraped off by the scraper blade 601, prevent these substances from adhering to the inner wall of the first circle tube 1 again, and avoid secondary pollution. By centrally storing scale or foreign matter in the storage bin 605, subsequent cleaning and processing are facilitated, thereby improving cleaning efficiency. At the same time, an elastic sealing portion can be provided at the end of the vertical plate 604, and the height of the vertical plate 604 is greater than the axial extension length of the scraper blade 601, so that the scraper blade 601, the vertical plate 604, the inner wall of the first circle tube 1, and the sealing plate 10 form a closed space, which is more convenient for cleaning scale or debris. The elastic sealing portion is made of flexible materials such as rubber and silicone. When the cleaning component 6 stops working, the elastic sealing portion can fit tightly against the inner wall of the sealing plate 10 to ensure the sealing effect. The closed space ensures the sealing during the cleaning process, prevents the leakage of scale or foreign matter, centrally processes the scraped scale or foreign matter, reduces secondary pollution and residue, protects system components, improves cleaning efficiency and quality, and ensures the long-term stable operation of the system.

[0028] like Figure 7 As shown, the cross section of the support rod 602 is streamlined, and the streamlined cross section helps to reduce the resistance generated when a fluid such as air or water flows, so that the fluid can bypass the support rod 602 more smoothly, reducing the formation of turbulence and eddies. The streamlined cross section can significantly improve the overall efficiency of the system, reduce energy loss, reduce local stress concentration, and enhance the stability and reliability of the structure; The angle between the support rod 602 and the center rod 603 is acute, and the angle range is 80-90°, so that the friction force received by the scraper blade 601 during operation can be decomposed. The friction force F received by the scraper blade 601 during operation can be decomposed into two components: a component F1 along the direction of the support rod 602 and a component F2 perpendicular to the direction of the support rod 602. Since the angle is acute, the vertical component F2 of the friction force is relatively small, which means that the vertical pressure applied to the support rod 602 is reduced, thereby reducing the torque that the support rod 602 needs to withstand. The torque τ can be calculated by the formula, where r is the length of the lever arm, F is the applied force, and θ is the angle between the force and the lever arm. This improves the stability and reliability of the system, optimizes the force transmission path, and ensures the efficient operation of the entire system.

[0029] like Fig. 9As shown, an inclined block sliding structure is arranged between the support rod 602 and the scraper blade 601, the top of the support rod 602 is an inclined surface, and the two ends of the inclined surface are respectively provided with a first stop plate 606 and a second stop plate 607, a first elastic element 608 is arranged between the scraper blade 601 and the first stop plate 606, and a second elastic element 609 is arranged between the scraper blade 601 and the second stop plate 607, the elastic modulus of the first elastic element 608 is greater than the elastic modulus of the second elastic element 609, when the cleaning component 6 starts to move, when the scraper blade 601 encounters resistance, the scraper blade 601 moves downward, pushing the second elastic element 609 to move. The elastic element 609 is deformed to prevent the scraper blade 601 from scratching the first circle tube 1; when the cleaning component 6 is working, the scraper blade 601 moves to the upper part of the sliding structure, and the first stop plate 606 and the first elastic element 608 limit the movement of the scraper blade 601, and limit the force between the scraper blade 601 and the first circle tube 1 to a suitable range, which can not only meet the requirements of cleaning scale, but also avoid scratching the first circle tube 1. At the same time, a limiting device is arranged outside the first elastic element 608 and the second elastic element 609 to prevent the first elastic element 608 and the second elastic element 609 from detaching from the top of the support rod 602.

[0030] Preferably, a positioning groove is also provided on the center rod 603, and the opening direction of the positioning groove is toward the sealing plate 10. When the cleaning component 6 stops working, the top surface of the positioning groove abuts against the sealing plate 10 to enhance the sealing effect. The top surface of the positioning groove abuts against the sealing plate 10 to form a physical barrier to prevent the fluid from leaking from the gap between the crankshaft 702 and the sealing plate 10. Combined with other sealing devices such as O-rings or mechanical seals, the overall sealing effect is further enhanced to ensure that there is no leakage in a static state.

[0031] like Figure 1 , Figure 4 As shown, the driving assembly 7 includes two moving units 701, two crankshafts 702 and a track 703. The track 703 is a semicircular structure. The moving unit 701 is arranged on the track 703. The moving unit 701 can move along the track 703. One end of the crankshaft 702 is connected to the moving unit 701. The end of the crankshaft 702 away from the moving unit 701 passes through the sealing plate 10 and is connected to the arc end of the center rod 603, which is used to drive the cleaning assembly 6 to move in the first circle tube 1. The two moving units 701 are symmetrically arranged about the inlet pipe 3. The track 703 is a semicircular structure, fixed on the outside of the first circle tube 1, providing a movement path for the motion unit 701. The motion unit 701 is set on the track 703 and can move along the track 703, so that the cleaning component 6 can move precisely along the predetermined path, avoiding deviation or jitter, and ensuring the precise movement of the cleaning component 6. One end of the crankshaft 702 is connected to the motion unit 701, and the other end passes through the sealing plate 10 and is connected to the center rod 603, which is used to transmit power and drive the cleaning component 6 to move. The two motion units 701 are symmetrically arranged about the inlet pipe 3, ensuring that the two ends of the cleaning component 6 can move synchronously, improving the uniformity and efficiency of the cleaning process, ensuring that the motion trajectory of the motion unit 701 is fixed, enhancing the stability of the system, ensuring the balance of the system, and reducing problems caused by uneven force on one side.

[0032] Preferably, a sealing structure is provided between the crankshaft 702 and the sealing plate 10. The sealing structure may be an O-ring, a flexible packing or other mechanical sealing structure. A dynamic O-ring is installed between the crankshaft 702 and the inner ring of the bearing. It is suitable for sealing rotating or reciprocating parts. Usually, materials with high wear resistance and chemical resistance are selected, such as polytetrafluoroethylene PTFE or fluororubber FKM. The O-ring sealing structure is simple, easy to install and has a good sealing effect. The dynamic O-ring design reduces friction and improves the efficiency of the system.

[0033] Preferably, a stuffing box can be installed on the sealing plate 10, and a flexible material such as graphite or polytetrafluoroethylene can be filled inside. The stuffing is compressed by a pressure cover to form a sealing effect. The stuffing sealing cost is low and is suitable for general working conditions. At the same time, the reciprocating mechanical seal structure is composed of a static ring, a dynamic ring, a spring and an auxiliary sealing ring. The dynamic ring reciprocates with the crankshaft 702, and the static ring is fixed on the sealing plate 10. Common materials for the dynamic and static rings include silicon carbide, alumina ceramics, stainless steel, etc., and the spring and the auxiliary sealing ring are made of corrosion-resistant and wear-resistant materials. The mechanical seal can provide a reliable sealing effect in high pressure and corrosive environments. The close fit of the dynamic and static rings ensures an extremely low leakage rate, thereby improving the safety and reliability of the system.

[0034] Preferably, the curvature radii of the crankshaft 702, the track 703 and the center rod 603 are equal, and are all equal to the annular curvature radius of the first circle tube 1, ensuring that the cleaning component 6 can maintain consistent curvature changes during movement and achieve synchronous movement. The consistent curvature radius keeps the relative positions of the various components fixed, reduces local stress concentration, and ensures the stability and reliability of the system.

[0035] Preferably, the two ends of the track 703 can be fixed on the two sealing plates 10 respectively, or fixed on the washing tower 9, or fixed on the bottom of the second coil tube 2; When both ends of the track 703 are fixed on the sealing plate 10, the sealing plate 10 can be directly used as a support point to ensure the stability of the track 703 without the need for an additional support structure, thereby simplifying the system design, reducing the complexity of installation, and making the entire system more compact and convenient for installation and maintenance. At the same time, the track 703 can connect the two sealing plates 10 of the first circle tube 1, which helps to improve the structural rigidity of the entire structure; When the track 703 is fixed on the washing tower 9, the solid structure of the washing tower 9 can be used to provide stable support to ensure that the track 703 will not be deformed or displaced due to external forces. By fixing the track 703 on the washing tower 9, the force generated by the motion unit 701 and the crankshaft 702 can be evenly dispersed to the washing tower 9, reducing local stress concentration. Since the washing tower 9 usually has high rigidity and stability, the track 703 fixed thereon can withstand greater external loads, enhance the overall stability of the system, reduce vibration transmission, and improve the smooth operation of the system; When the track 703 is fixed to the bottom of the second circle tube 2, the existing pipeline structure can be fully utilized and fixed at multiple locations along the track 703 to improve the structural rigidity of the track 703, reduce the vibration caused by the motion unit 701, and improve the running stability of the system.

[0036] A plurality of brackets 8 can be arranged along the circumference of the washing tower 9. In the present invention, the brackets 8 are arranged below the inlet pipe 3, the first outlet pipe 4, the second outlet pipe 5 and the second coil pipe 2. The brackets 8 can further reduce the vibration generated by the movement of the fluid in the inlet pipe 3, the first outlet pipe 4 and the second outlet pipe 5 to avoid affecting the distribution of the fluid. The brackets 8 can be one of a spring damping bracket, a rigid bracket or a flexible bracket. The spring vibration-damping bracket includes elastic elements such as springs or rubber and a fixed base, which can effectively absorb the vibration from the pipeline system, reduce the impact on the surrounding structure, extend the life of the equipment, reduce the wear and fatigue damage caused by vibration, and improve the reliability and safety of the system; The rigid bracket is made of metal or other high-strength materials and is firmly installed on the supporting structure by welding, bolts, etc. It provides strong support and has extremely high stability, ensuring that the pipeline system can maintain the correct posture under any circumstances; The flexible bracket is made of flexible materials such as rubber or polyurethane and a fixed base, allowing the pipeline to bend and deform within a certain range. It can effectively absorb vibration and impact and reduce damage to the pipeline system.

[0037] like Figure 6As shown, the sealing plate 10 includes a sealing block 1001, a drain port 1002 and a partition 1003. The sealing block 1001 is arranged on a side where the partition 1003 is connected to the first coil 1 (i.e., inside the first coil 1), and the drain port 1002 is arranged at the bottom of the partition 1003 for discharging scale or foreign matter. The sealing block 1001 can be closely fitted with the storage bin 605 to form a closed space, preventing the fluid in the first tube 1 from leaking out from the gap, thereby ensuring the sealing performance; The drain outlet 1002 is arranged at the bottom of the partition 1003, so as to directly discharge scale or foreign matter and simplify the cleaning process. By rationally designing the position and size of the drain outlet 1002, blockage can be effectively prevented to ensure long-term stable operation of the system.

[0038] like Figure 4 As shown, a water distribution member 12 is further provided at the position where the inner wall of the first tube circle 1 is directly opposite to the interface of the inlet tube 3. The water distribution member 12 is used to evenly distribute the fluid in the inlet tube 3. Through the guidance of the water distribution member 12, the fluid can enter the first tube circle 1 more smoothly, reducing the turbulence effect, and can also effectively evenly distribute the incoming fluid to the entire pipeline system, avoiding local overload or unevenness, thereby improving the stability and efficiency of the system; The water distribution member 12 can be welded to the first tube coil 1, or can be detachably connected to the first tube coil 1; When the water distribution piece 12 is directly welded to the inner wall of the first circle tube 1, the integrity and rigidity of the structure are enhanced, and the risk of loosening due to mechanical vibration is reduced. When the water distribution piece 12 is connected to the first circle tube 1 by bolts or screws, the water distribution piece 12 can be easily installed and removed, which is convenient for daily maintenance, cleaning and replacement of parts, and improves operational flexibility.

[0039] like Figure 2 As shown, both the first outlet pipe 4 and the second outlet pipe 5 are provided with a valve 13, the valve 13 is a proportional valve, and the valve 13 includes a first valve 1301 and a second valve 1302, the first valve 1301 is provided on the first outlet pipe 4, and the second valve 1302 is provided on the second outlet pipe 5; The proportional valve can linearly adjust the opening according to the input signal, such as current or voltage, so as to achieve precise control of the fluid flow, improve the flexibility and response speed of the system, and by integrating with the control system, such as PLC or DCS, the proportional valve can monitor and adjust the flow in real time to ensure that the system is always in the best operating state, so that the first valve 1301 and the second valve 1302 can independently control the flow of the first outlet pipe 4 and the second outlet pipe 5, respectively, to achieve dynamic balance of the load, avoid pressure fluctuations and vibration problems caused by uneven flow, and respond quickly when abnormal flow or pressure is detected to close or limit the flow.

[0040] The present invention is also provided with a control system for controlling the driving component 7 to drive the cleaning component 6 to clean the scale on the inner wall of the first circle tube 1. The control system includes a sensor, a controller, an actuator, etc., which are used to monitor and control the working state of the cleaning component 6. The driving component 7 is responsible for driving the cleaning component 6 to perform reciprocating motion or other forms of motion to achieve effective cleaning of the scale on the inner wall of the first circle tube 1. The control system can automatically control the operation of the cleaning component 6 according to a preset program without manual intervention, thereby improving work efficiency. The sensor can monitor the working status of the cleaning component 6 in real time, such as position, speed, pressure, etc., to ensure that it is always in the best working state. The built-in diagnostic function can also help quickly locate and solve problems, shortening maintenance time; setting up an automated control system simplifies the operating process, reduces the need for manual intervention, reduces training costs, and ensures the stability and reliability of the cleaning process.

[0041] A method for using a manifold with a self-cleaning function comprises the following specific steps: S1, after the manifold runs continuously for T time, the control system drives the two motion units 701 to move in opposite directions along the track 703, and the motion units 701 push the cleaning assembly 6 to move in the first circle tube 1 through the crankshaft 702; S2, when the cleaning components 6 move to the set position, the two cleaning components 6 stop moving, the control system drives the two motion units 701 to move in the opposite direction, and the cleaning components 6 start working; S3, during the cleaning process, the scraper blade 601 is close to the inner wall of the first coil 1 to remove scale, and the block scale enters the storage bin 605; S4, when the cleaning assembly 6 moves to the stop zone, the storage bin 605 abuts against the sealing plate 10; S5, open the drain outlet 1002 from the outside of the sealing plate 10, clean the scale inside the storage bin 605, and then close the drain outlet 1002, and the cleaning work is completed.

[0042] The control system can automatically detect the operating time of the collecting pipe to ensure that cleaning is performed at the appropriate time, reducing manual intervention. The coordinated work of the motion unit 701 and the crankshaft 702 realizes precise control of the cleaning component 6 to ensure that it can cover the entire area that needs to be cleaned. The design of the storage bin 605 allows the scraped scale to be concentrated in this area, which is convenient for subsequent cleaning and processing, thereby improving the cleaning efficiency. By centrally storing scale or foreign matter and quickly discharging it through the drain outlet 1002, subsequent cleaning and maintenance work is simplified, reducing maintenance costs and time.

[0043] In summary, this device not only improves the cleaning efficiency and quality, but also optimizes the overall performance of the system and ensures long-term stable operation.
