Description

Technical Field

[0001] This invention relates to the field of metal material processing technology, and in particular to a rinsing mechanism and a rinsing device and method for rinsing carbon steel plates before galvanizing. Background Technology

[0002] In the pretreatment process of carbon steel sheets before galvanizing, the rinsing stage is crucial. Traditional rinsing equipment has several shortcomings when cleaning steel strips. When cleaning the sides of the steel strip, the cleaning components rotate in the same direction as the steel strip's conveying direction, making it difficult to thoroughly remove side stains and resulting in poor cleaning effects. Regarding the cleaning of the upper and lower surfaces of the steel strip, the upper and lower cleaning components cannot move synchronously, leading to asynchronous cleaning. Furthermore, the equipment cannot effectively support the steel strip during the cleaning process, making it prone to bending and affecting quality.

[0003] Meanwhile, the cleaning components move in only one direction, fixing the cleaning direction of the steel belt and preventing cleaning from different directions, thus reducing the cleaning effect. Furthermore, traditional equipment does not effectively control the contact pressure between the cleaning components and the steel belt, affecting the thoroughness of the cleaning process. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing steel strip cleaning, such as incomplete cleaning, easy bending, and single cleaning direction, and to propose a rinsing mechanism and rinsing equipment and method for carbon steel plates before galvanizing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The rinsing system includes:

[0007] The spray washing tank has multiple support plates fixed on both sides of its top. An upper liquid storage pipe is fixedly connected between two adjacent support plates. Multiple lower liquid storage pipes are fixedly connected inside the spray washing tank, and the lower liquid storage pipes are located directly below the adjacent upper liquid storage pipes. Multiple spray nozzles are fixedly connected to one side of both the upper and lower liquid storage pipes. The multiple spray nozzles are used to wash the front and back sides of the steel strip.

[0008] Multiple cleaning rollers are located inside a spray washing tank for cleaning both sides of the steel belt.

[0009] Multiple sets of side cleaning structures are installed inside the spray washing tank to drive the cleaning rollers to rotate. The direction of rotation of the cleaning rollers is opposite to the direction of the steel belt conveyor.

[0010] Multiple surface cleaning structures are fixed inside the spray washing tank, consisting of two horizontal plates I and two horizontal plates II. The two horizontal plates I are arranged vertically, and the two horizontal plates II are located above and below the two horizontal plates I, respectively, for simultaneous cleaning of the upper and lower surfaces of the steel strip.

[0011] Two sets of synchronously operating structures, and a driving structure that drives the two sets of synchronously operating structures to move alternately;

[0012] The side cleaning structure includes a concave groove, a U-shaped plate, an elastic spring, a rotating shaft I, a rubber roller, a rotating shaft II, a gear I, and a gear II. The U-shaped plate moves towards the steel belt under the elastic force of the elastic spring. The rubber roller is in close contact with the side of the steel belt. The movement of the steel belt drives the rubber roller to rotate. The rubber roller drives the gear I to rotate through the rotating shaft I. The gear I and gear II mesh to drive the cleaning roller cylinder to rotate. The diameter of gear I is larger than the diameter of gear II to increase the rotation speed of the cleaning roller cylinder.

[0013] The synchronous operation structure includes a sliding guide groove, a sliding base, a rotating shaft, a cleaning disc brush, a protective housing, a drive motor, a connecting rod, and a connecting plate. Two adjacent sliding bases move synchronously through the connecting rod and the connecting plate, so that the cleaning disc brush cleans the upper and lower surfaces of the steel belt synchronously and supports the steel belt to prevent the steel belt from bending.

[0014] In one possible design, the side cleaning structure further includes a concave groove on the inner wall of one side of the spray washing tank, a U-shaped plate slidably connected in the concave groove, a plurality of fixing rods fixedly connected to one side of the U-shaped plate, one end of the plurality of fixing rods slidably extending to one side of the spray washing tank, and an elastic spring sleeved on the outer wall of the plurality of fixing rods, the two ends of the elastic springs being fixedly connected to one side of the inner wall of the concave groove and one side of the U-shaped plate respectively through spring seats;

[0015] The U-shaped plate is longitudinally rotatably connected to two rotating shafts I. Rubber rollers are fixedly sleeved on the outer walls of the two rotating shafts I. Both rubber rollers abut against the side of the steel belt and are located on both sides of the cleaning roller brush cylinder.

[0016] The U-shaped plate is longitudinally rotatably connected to a rotating shaft II, and the cleaning roller brush cylinder is fixedly sleeved on the outer wall of the rotating shaft II.

[0017] The top ends of the two rotating shafts I extend rotatably to the top of the U-shaped plate and are fixedly connected to gear I. The top end of the rotating shaft II extends rotatably to the top of the U-shaped plate and is fixedly connected to gear II. The two sides of gear II mesh with the two gears I.

[0018] The top of the U-shaped plate is fixedly connected to a protective shell I, which is used to protect gear I and gear II.

[0019] In one possible design, the synchronous operation structure includes two sliding guide grooves, which are respectively set in two horizontal plates I. Each sliding guide groove is slidably connected to a sliding base, and each sliding base is rotatably penetrated by a rotating shaft. Each of the two rotating shafts is provided with a cleaning disc brush at one end that is close to each other.

[0020] The ends of the two rotating shafts that are far apart from each other are rotatably connected to protective housings, and the sides of the two protective housings that are far apart from each other are slidably connected to two horizontal plates II respectively;

[0021] Both protective housings are equipped with drive motors. The output shafts of the two drive motors are fixedly connected to the ends of the corresponding rotating shafts via couplings, which are used to drive the cleaning disc brush to rotate.

[0022] Each of the two sliding bases has a connecting rod fixedly connected to one side, and one end of each connecting rod is fixedly connected to the same connecting plate.

[0023] In one possible design, the drive structure includes a gear III, which is rotatably connected to the top of an upper horizontal plate I. Two rack members are slidably connected to the top of the upper horizontal plate I. The rack members mesh with the gear III, and the sides of the two rack members that are far apart from each other are respectively fixedly connected to two corresponding sliding bases.

[0024] A protective shell II is fixedly connected to the top of the upper horizontal plate I to protect the gear III and rack components;

[0025] Among them, the drive motor drives gear III to reciprocate, and gear III drives the sliding base to move alternately through the rack component, so that the cleaning disc brush reciprocates along the sliding guide groove to clean the steel belt in different directions.

[0026] In one possible design, a fixed sleeve is slidably fitted on the outer wall of the rotating shaft, and a rotating disk is fixedly connected to the bottom end of the fixed sleeve, with the cleaning disk brush fixedly connected to the bottom of the rotating disk.

[0027] A tension spring is fixedly connected between the bottom end of the rotating shaft and the top of the rotating disk via a spring seat, which is used to pull the rotating disk upward.

[0028] An electromagnetic magnet is fixedly embedded at the bottom of the rotating shaft, and a magnetic iron block is fixedly connected to the top of the rotating disk. A repulsive force is generated between the electromagnetic magnet and the magnetic iron block. The repulsive force is greater than the tension of the tension spring, which is used to drive the cleaning disk brush to stick tightly to the surface of the steel belt.

[0029] In one possible design, two isolation plates are fixedly connected inside the spray washing tank, and the isolation plates and the spray washing tank form a liquid storage cavity.

[0030] A filter screen is fixedly connected inside the liquid storage chamber and located below the lower liquid storage pipe for separating rinsing liquid from large particles of dirt.

[0031] A booster water pump is fixedly connected to one side of the spray washing tank. The inlet of the booster water pump is connected to the storage chamber through a hose, and the outlet is connected to the delivery pipeline system through a hose. The delivery pipeline system is fixedly connected to the upper and lower storage pipes and is used for circulating the rinsing solution.

[0032] In one possible design, the angle between the spray nozzles on the lower and upper liquid storage pipes and the steel strip is 30°-60°.

[0033] In one possible design, two scraping plates arranged vertically are fixedly connected inside the spray washing tank. The two scraping plates are located above and below the steel strip, and rubber pads are fixedly connected to the sides that are close to each other, for scraping off the rinsing liquid and dirt from the top and bottom of the steel strip.

[0034] A guide plate is fixedly connected to the bottom of the scraper located below, which is used to guide the scraped material to the liquid storage chamber.

[0035] The rinsing equipment for carbon steel plates before galvanizing includes the rinsing mechanism mentioned above, and also includes a conveying support, a spray neutralization treatment device, a multi-stage spray rinsing system, a pure water spray treatment device and a hot air circulating dryer arranged from left to right.

[0036] The spray washing tank is located between the conveyor support and the spray neutralization treatment device;

[0037] The conveying support consists of two conveying rollers for conveying steel strips;

[0038] The spray neutralization treatment device is equipped with multiple spray pipes for spraying neutral or weakly alkaline water to neutralize acid solutions.

[0039] The multi-stage spray rinsing system is equipped with multiple spray heads for spraying industrial water, demineralized water and hot demineralized water;

[0040] The pure water spray treatment device is equipped with multiple spray heads for spraying ultrapure water;

[0041] The hot air circulating dryer is used to dry steel strips.

[0042] In this application, the rinsing method for carbon steel plates using the aforementioned rinsing equipment before galvanizing includes the following steps:

[0043] S1. Steel strip conveying: The carbon steel plate strip is conveyed to the right by two conveying rollers in the conveying bracket, so that the steel strip enters the processing flow.

[0044] S2. Pre-rinse: When the steel strip passes through the spray washing tank, it is pre-rinsed to remove large particles of dirt, dust and loose oil from the surface of the sheet, reducing the load on subsequent processes.

[0045] S3. Jet rinsing: The rinsing liquid in the spray washing tank is sprayed onto the steel belt through multiple spray nozzles set on the upper and lower storage pipes using a booster water pump. The top and bottom of the steel belt are rinsed, and the angle between the spray nozzles and the running steel belt is 30 to 60 degrees to enhance the impact force of the rinsing liquid and improve the rinsing efficiency.

[0046] S4. Side Cleaning: When the steel belt enters the spray washing tank, the U-shaped plate moves towards the steel belt under the elastic force of the spring, so that the rubber roller is in close contact with the side of the steel belt. The movement of the steel belt drives the rubber roller to rotate. The rubber roller drives the first gear to rotate through the first shaft. The first gear drives the cleaning roller to rotate through the second gear. The diameter of the first gear is larger than the diameter of the second gear to increase the rotation speed of the cleaning roller. The rotation direction of the cleaning roller is opposite to the movement direction of the steel belt, so as to thoroughly clean the side of the steel belt.

[0047] S5. Top and bottom cleaning: The rotating shaft is driven by the drive motor to rotate, and the rotating shaft drives the rotating disk and cleaning disk brush to rotate through the fixed sleeve, so that the cleaning disk brush can clean the top and bottom of the steel belt simultaneously.

[0048] S6. Cleaning disc brush reciprocating movement: The two adjacent cleaning disc brushes above the synchronous drive steel belt move back and forth alternately. The third gear is driven to rotate back and forth by the drive motor. The third gear drives the two adjacent sliding bases to move back and forth alternately through two rack components. The upper and lower adjacent sliding bases move synchronously through the connecting rod and connecting plate, so that the upper and lower cleaning disc brushes move back and forth along the sliding guide groove trajectory, cleaning the steel belt from different directions and providing support to prevent the steel belt from bending.

[0049] S7. Scrape off residue: After the cleaning disc brush has finished cleaning, use the scraper and rubber pad to stick to the upper and lower surfaces of the steel belt to scrape off the residual rinsing liquid and dirt, which will facilitate subsequent rinsing.

[0050] S8. Neutralization and rinsing: The steel belt is successively subjected to neutralization and rinsing treatment by a spray neutralization treatment device.

[0051] S9. Deep cleaning: The steel belt undergoes deep cleaning through a multi-stage spray rinsing system;

[0052] S10, Surface activation: The steel strip undergoes surface activation treatment using a pure water spray treatment device;

[0053] S11. Drying: The steel belt is dried by a hot air circulating dryer to complete the entire cleaning process.

[0054] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0055] In this invention, a plurality of fixing rods are fixed to one side of the U-shaped plate. The two ends of the elastic spring are respectively fixedly connected to the inner wall of one side of the concave groove and the side of the U-shaped plate through spring seats. Two rotating shafts I are longitudinally rotatably connected inside the U-shaped plate. The cleaning roller is fixedly sleeved on the outer wall of the rotating shaft II. Gear I is fixed to the top of each of the two rotating shafts I. Gear II is fixedly connected to the top of the rotating shaft II. The rubber roller is in close contact with the side of the steel belt under the elastic force of the elastic spring. When the steel belt moves, it drives the gear I to rotate through the rubber roller. The gear I drives the cleaning roller to rotate through the gear II. The rotation direction of the cleaning roller is opposite to the movement direction of the steel belt, which can fully clean the side of the steel belt and ensure that the steel belt is thoroughly cleaned.

[0056] In this invention, each of the two sliding guide grooves is slidably connected to a sliding base, and each of the two sliding bases is rotatably connected to a rotating shaft. A cleaning disc brush is provided at the end of each rotating shaft that is close to each other, and a protective housing is rotatably connected at the ends of each rotating shaft that are far from each other. The protective housing is slidably connected to two horizontal plates II. A connecting rod is fixed to one side of each of the two sliding bases, and a common connecting plate is fixed to one end of each connecting rod. The two adjacent sliding bases move synchronously through the cooperation of the connecting rod and the connecting plate. Therefore, the two cleaning disc brushes can simultaneously clean both sides of the steel strip and support the steel strip during the cleaning process, preventing the steel strip from bending during cleaning and affecting its quality.

[0057] In this invention, the driving structure includes a gear III, which rotates on the top of a horizontal plate I. Two rack members are slidably connected to the top of the horizontal plate I, and the sides of the two rack members that are far apart from each other are respectively fixedly connected to two corresponding sliding bases. The gear III is driven to reciprocate by a drive motor, and the gear III drives the two adjacent sliding bases to move alternately back and forth through the two rack members. This allows the cleaning disc brush to clean the steel belt from different directions as it moves back and forth along the trajectory of the sliding guide groove, thereby changing the direction of the cleaning disc brush on the steel belt and improving the cleaning effect.

[0058] In this invention, during side cleaning, the rubber rollers, under the action of elastic springs, adhere tightly to the steel belt, driving the cleaning roller cylinder to rotate in the opposite direction, which can thoroughly clean the sides of the steel belt. For surface cleaning, the upper and lower cleaning discs move synchronously, which can clean both the upper and lower surfaces of the steel belt at the same time, and support the steel belt during the cleaning process to prevent bending. The drive structure makes the cleaning discs move alternately back and forth, which can clean the steel belt from different directions and improve the cleaning effect. In addition, by using an electromagnet and a magnetic iron block, the contact pressure between the cleaning discs and the steel belt can be adjusted to ensure thorough cleaning and effectively improve the rinsing quality of carbon steel plates before galvanizing.

[0072] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0073] In one embodiment: Refer to Figures 1-10 The rinsing mechanism relates to the field of metal material processing technology and mainly includes a spray washing tank 1, a spray system, a side cleaning structure, a surface cleaning structure, a drive structure, and a rinsing liquid circulation system.

[0074] Reference Figures 1-3 The spray washing tank 1, as the main load-bearing component of the entire rinsing mechanism, has multiple support plates 2 fixed on both sides of its top. An upper liquid storage pipe 3 is fixed between two adjacent support plates 2. Multiple lower liquid storage pipes 4 are fixed inside the spray washing tank 1, and the lower liquid storage pipes 4 are located directly below the adjacent upper liquid storage pipes 3. Multiple spray nozzles 5 are fixed to one side of both the upper and lower liquid storage pipes 3 and 4. The angle between the multiple spray nozzles 5 and the steel belt is 30°-60°. This angle setting allows the sprayed rinsing liquid to impact the steel belt surface at a suitable angle, improving the rinsing effect.

[0075] In practical applications, the angle between the spray nozzle 5 and the steel strip can be adjusted within this range according to factors such as the material of the steel strip, the degree of surface dirt, and the pressure of the rinsing solution, in order to achieve the best rinsing effect. For example, when the dirt on the steel strip surface is more stubborn, the angle can be appropriately increased so that the rinsing solution acts on the steel strip surface with greater impact force; when the steel strip material is thin or the surface is more sensitive, the angle can be decreased to avoid excessive impact of the rinsing solution on the steel strip.

[0076] Reference Figure 2 and Figure 3 The spray system consists of an upper storage pipe 3, a lower storage pipe 4, spray nozzles 5, a booster water pump 7, and a delivery pipeline system 6. The booster water pump 7 is fixed to one side of the spray washing tank 1, with its inlet end connected to the storage chamber via a hose, and its outlet end connected to the delivery pipeline system 6 via a hose. The delivery pipeline system 6 is then fixedly connected to multiple upper and lower storage pipes 3 and 4. During operation, the booster water pump 7 extracts the rinsing solution collected in the storage chamber and injects it into the upper and lower storage pipes 3 and 4 through the delivery pipeline system 6, then sprays it at high speed from the spray nozzles 5 to rinse both sides of the steel strip.

[0077] To ensure the stable operation of the spray system and a good rinsing effect, the selection of the booster water pump 7 is crucial. The appropriate power and flow rate of the booster water pump 7 should be selected based on factors such as the scale of the rinsing mechanism, the conveyor speed of the steel belt, and the required rinsing pressure. For example, for larger-scale rinsing mechanisms, the steel belt conveyor speed is faster, requiring higher rinsing pressure and flow rate; in this case, a booster water pump 7 with higher power and flow rate should be selected. Conversely, for smaller-scale rinsing mechanisms, a booster water pump 7 with lower power and flow rate can be selected to reduce energy consumption and costs.

[0078] Reference Figure 2 and Figure 4 A side cleaning structure is installed inside the spray washing tank 1 to clean both sides of the steel belt. The side cleaning structure has a concave groove 8 on one inner wall of the spray washing tank 1, within which a U-shaped plate 9 is slidably connected. Multiple fixing rods 17 are fixed to one side of the U-shaped plate 9, with one end of each rod extending slidably to one side of the spray washing tank 1. Elastic springs 18 are fitted onto the outer walls of each fixing rod 17, with the following parameters: wire diameter 0.5-2mm, outer diameter 5-20mm, free length 20-100mm, and maximum working load 10-100N. The two ends of the elastic springs 18 are fixedly connected to one inner wall of the concave groove 8 and one side of the U-shaped plate 9 respectively via spring seats. Their function is to push the U-shaped plate 9 towards the steel belt, causing the cleaning roller brush 13 to exert pressure on the side of the steel belt, ensuring a cleaning effect.

[0079] Reference Figure 2 , Figure 4 and Figure 5Two rotating shafts I10 are longitudinally rotatably connected inside the U-shaped plate 9. Rubber rollers 11 are fixedly fitted onto the outer walls of both rotating shafts I10, and both rubber rollers 11 abut against the sides of the steel belt. The two rubber rollers 11 are located on opposite sides of the cleaning roller brush cylinder 13. A rotating shaft II12 is also longitudinally rotatably connected inside the U-shaped plate 9, and the cleaning roller brush cylinder 13 is fixedly fitted onto the outer wall of the rotating shaft II12. The top ends of both rotating shafts I10 extend rotatably above the U-shaped plate 9 and are fixedly fitted with gears I14. The top end of rotating shaft II12 extends rotatably above the U-shaped plate 9 and is fixedly fitted with gears II15. The two sides of gears II15 mesh with the two gears I14 respectively. The diameter of gear I14 is larger than the diameter of gear II15. This design increases the rotational speed of the cleaning roller brush cylinder 13, thereby improving its cleaning efficiency. For example, when the diameter ratio of gear I14 to gear II15 is 2:1, gear I14 will rotate once and gear II15 will rotate twice, thereby driving the cleaning roller brush 13 to rotate quickly and better remove dirt from the side of the steel belt.

[0080] Reference Figure 2 , Figure 4 and Figure 5 The top of the U-shaped plate 9 is fixed with a protective shell I16 to protect gears I14 and II15, preventing them from being disturbed or damaged by external debris during operation. In actual operation, the U-shaped plate 9 moves towards the steel belt under the elastic force of the elastic spring 18. The rubber roller 11 is in close contact with the side of the steel belt. When the steel belt moves, it drives the rubber roller 11 to rotate. The rubber roller 11 drives gear I14 to rotate through the rotating shaft I10. Gear I14 drives the cleaning roller brush cylinder 13 to rotate through gear II15. Since the rotation direction of the cleaning roller brush cylinder 13 is opposite to the movement direction of the steel belt, it can thoroughly clean the side of the steel belt, ensuring a comprehensive cleaning of the steel belt.

[0081] Reference Figure 1 , Figure 2 and Figure 6 The surface cleaning structure is used for simultaneous cleaning of the upper and lower surfaces of the steel strip. It includes two horizontal plates I19 and two horizontal plates II20 fixed inside the spray washing tank 1. The two horizontal plates I19 are arranged vertically, and the two horizontal plates II20 are located above and below the two horizontal plates I19. It also includes two sets of synchronous operation structures and a drive structure for driving the two sets of synchronous operation structures to move alternately.

[0082] Reference Figure 7 , Figure 8 and Figure 10The synchronous operation structure includes two sliding guide grooves 21, which are respectively set in two horizontal plates I19. Each sliding guide groove 21 is slidably connected to a sliding base 22, and each sliding base 22 has a rotating shaft 23 rotatably passing through it. Cleaning disc brushes 30 (which can be carbon fiber-nylon composite bristles) are provided at the ends of the two rotating shafts 23 that are close to each other. The two cleaning disc brushes 30 are used to clean the top and bottom of the steel strip. A fixing sleeve 28 is slidably fitted onto the outer wall of the rotating shaft 23. A rotating disk 29 is fixed to the bottom end of the fixing sleeve 28, and the cleaning disc brushes 30 are fixed to the bottom of the rotating disk 29. A tension spring 31 is fixed between the bottom end of the rotating shaft 23 and the top of the rotating disk 29 via a spring seat. The parameters of the tension spring 31 are: wire diameter 0.3-1.5mm, outer diameter 3-15mm, free length 10-50mm, and maximum working load 5-50N. Its function is to pull the rotating disk 29 upward to prevent the rotating disk 29 from obstructing the steel belt from passing through the spray washing tank 1.

[0083] Reference Figure 10 An electromagnetic magnet 32 ​​is fixedly embedded at the bottom of the rotating shaft 23, and a magnetic iron block 33 is fixed at the top of the rotating disk 29. A repulsive force is generated between the electromagnetic magnet 32 ​​and the magnetic iron block 33, and this repulsive force is greater than the tension of the tension spring 31. This force drives the cleaning disc brush 30 to move and adhere closely to the surface of the steel belt, ensuring that the cleaning disc brush 30 thoroughly cleans the steel belt. In actual operation, the current of the electromagnetic magnet 32 ​​can be adjusted according to the thickness and surface condition of the steel belt, thereby changing the repulsive force between the electromagnetic magnet 32 ​​and the magnetic iron block 33 to ensure that the cleaning disc brush 30 maintains appropriate contact pressure with the steel belt surface.

[0084] Reference Figures 6-9 Each of the two rotating shafts 23 has a protective housing 24 rotatably connected to its far ends. The far sides of the two protective housings 24 are slidably connected to two horizontal plates II 20, respectively. Each of the two protective housings 24 has a drive motor 25 fixed inside. The output shafts of the two drive motors 25 are fixedly connected to the ends of the corresponding rotating shafts 23 via couplings, and are used to drive the cleaning disc brush 30 to rotate and clean the steel belt through the rotating shafts 23.

[0085] Reference Figure 9 Each of the two sliding bases 22 has a connecting rod 26 fixed to one side. One end of each connecting rod 26 extends slidably to one side of the spray washing tank 1 and is fixed with the same connecting plate 27. The connecting plate 27 drives the two rotating shafts 23 to move synchronously through the two connecting rods 26. The two adjacent sliding bases 22 move synchronously through the cooperation of the connecting rods 26 and the connecting plate 27. Therefore, the two cleaning disc brushes 30 can clean the upper and lower surfaces of the steel belt simultaneously and support the steel belt during the cleaning process, preventing the steel belt from bending during cleaning and affecting its quality.

[0086] Reference Figure 7 and Figure 8 The drive structure, which drives two sets of synchronously operating structures to move alternately, includes a gear III 34 that rotates on top of the upper horizontal plate I 19. Two rack members 35 are slidably connected to the top of the upper horizontal plate I 19, meshing with the gear III 34. The sides of the two rack members 35 that are far apart from each other are fixedly connected to two corresponding sliding bases 22. A protective shell II 36 is fixed to the top of the upper horizontal plate I 19, and the protective shell II 36 protects the gear III 34 and the rack members 35.

[0087] During operation, the drive motor drives gear III 34 to reciprocate. Gear III 34, through two rack components 35, drives two adjacent sliding bases 22 to move alternately back and forth. This allows the cleaning disc brush 30 to clean the steel belt from different directions as it moves back and forth along the sliding guide groove 21, changing the cleaning direction of the cleaning disc brush 30 on the steel belt and improving the cleaning effect. For example, when gear III 34 rotates clockwise by a certain angle, it drives one rack component 35 to move to the right and the other rack component 35 to move to the left, causing the two sliding bases 22 to drive the corresponding cleaning disc brush 30 to move in opposite directions. When gear III 34 rotates counterclockwise by the same angle, the two cleaning disc brushes 30 move back in opposite directions. This reciprocating motion achieves all-round cleaning of the steel belt surface.

[0088] Reference Figure 2 Two isolation plates 40 are fixed inside the spray washing tank 1, and the isolation plates 40 and the spray washing tank 1 form a liquid storage chamber for storing rinsing solution. A filter screen 41 is fixed inside the liquid storage chamber, located below the lower liquid storage pipe 4. The size of the pores of the filter screen 41 is selected according to the size of the dirt particles that need to be filtered in the rinsing solution. Generally, a filter screen 41 with a pore size of 0.1-1mm can be used. Its function is to separate the rinsing solution from large particles of dirt during the rinsing process of the steel belt, ensuring the cleanliness of the rinsing solution injected into the upper liquid storage pipe 3 and the lower liquid storage pipe 4, and improving the rinsing effect.

[0089] Reference Figure 12The rinsing equipment for carbon steel plates before galvanizing includes the aforementioned rinsing mechanism, and further includes, from left to right, a conveyor support 42, a spray neutralization treatment device 43, a multi-stage spray rinsing system 44, a pure water spray treatment device 45, and a hot air circulating dryer 46. The spray washing tank 1 is located between the conveyor support 42 and the spray neutralization treatment device 43. The conveyor support 42 consists of two conveyor rollers used to convey the steel strip to the right. The spray neutralization treatment device 43 is equipped with multiple spray pipes for spraying neutral or weakly alkaline water onto the steel strip to neutralize residual acid (such as hydrochloric acid, sulfuric acid, etc.) on the surface of the plate. The system prevents acidic substances from corroding the substrate or contaminating the galvanizing bath. The multi-stage spray rinsing system 44 has multiple spray heads installed through pipes to sequentially spray industrial water, demineralized water, and hot demineralized water onto the steel strip. This thoroughly removes micron-level dirt, ions, and residual chemicals from the surface of the sheet, ensuring surface cleanliness meets galvanizing requirements. The pure water spray treatment device 45 has multiple spray heads fixed through pipes to spray ultrapure water onto the steel strip, activating the surface, improving the adhesion between the galvanized layer and the substrate, and removing any remaining impurities. The hot air circulating dryer 46 is used to dry the steel strip.

[0090] In another embodiment: Refer to Figure 2 and Figure 11 The spray washing tank 1 contains two scraper blades 37 arranged vertically, one above and one below the steel belt. Rubber pads 38 are fixed to the sides of the two scraper blades 37 that are close to each other, used to scrape off rinsing liquid and dirt from the top and bottom of the steel belt. A guide plate 39 (with a nano-hydrophobic coating) is fixed to the bottom of the lower scraper blade 37, used to guide the rinsing liquid and dirt scraped off by the lower scraper blade 37 into the storage chamber, enabling further recycling of the rinsing liquid and reducing resource waste.

[0091] The rinsing method for carbon steel plates using rinsing equipment before galvanizing includes the following steps:

[0092] S1. The carbon steel plate strip is conveyed to the right by two conveying rollers in the conveying bracket 42. When the steel strip passes through the spray washing box 1, it is pre-washed to remove large particles of dirt, dust and loose oil on the surface of the plate, reducing the load of subsequent processes. Then the steel strip passes through the spray neutralization treatment device 43, the multi-stage spray rinsing system 44, the pure water spray treatment device 45 and the hot air circulating dryer 46 in sequence to perform neutralization rinsing, deep cleaning, surface activation and drying treatments.

[0093] S2. When the steel strip is pre-rinsed through the spray washing tank 1, the booster water pump 7 sprays the rinsing liquid in the spray washing tank 1 through multiple spray nozzles 5 set on the upper liquid storage pipe 3 and the lower liquid storage pipe 4 to rinse the top and bottom of the steel strip. The angle between the spray nozzles 5 and the running steel strip is 30°-60° to enhance the impact force of the rinsing liquid on the steel strip and improve the rinsing efficiency.

[0094] S3. When the steel belt enters the spray washing tank 1, the U-shaped plate 9 moves towards the steel belt under the elastic force of the elastic spring 18. The rubber roller 11 is in close contact with the side of the steel belt, and the steel belt drives the rubber roller 11 to rotate when it moves. The rubber roller 11 drives the gear I 14 to rotate through the rotating shaft I 10. The gear I 14 drives the cleaning roller brush cylinder 13 to rotate through the gear II 15. The diameter of the gear I 14 is larger than the diameter of the gear II 15, which can increase the rotation speed of the cleaning roller brush cylinder 13. The rotation direction of the cleaning roller brush cylinder 13 is opposite to the movement direction of the steel belt, which can fully clean the side of the steel belt and ensure that the steel belt is thoroughly cleaned.

[0095] S4. The rotating shaft 23 is driven to rotate by the drive motor 25. The rotating shaft 23 drives the rotating disk 29 and the cleaning disk brush 30 to rotate through the fixed sleeve 28. Thus, the cleaning disk brush 30 can clean the top and bottom of the steel belt simultaneously. In addition, to improve the cleaning effect of the steel belt, the two adjacent cleaning disk brushes 30 above the steel belt can be driven to move back and forth alternately. Thus, the cleaning disk brush 30 can clean the steel belt from different directions as it moves back and forth along the trajectory of the sliding guide groove 21, changing the cleaning direction of the cleaning disk brush 30 on the steel belt and improving the cleaning effect. Specifically, the gear III 34 is driven to rotate back and forth by the drive motor. The gear III 34 drives the two adjacent sliding bases 22 to move back and forth alternately through the two rack components 35. In addition, the two adjacent upper and lower sliding bases 22 move synchronously through the cooperation of the connecting rod 26 and the connecting plate 27. Therefore, the two upper and lower cleaning disk brushes 30 can clean the upper and lower surfaces of the steel belt simultaneously and support the steel belt during the cleaning process of the two cleaning disk brushes 30, so as to prevent the steel belt from bending during the cleaning process and affecting the quality of the steel belt.

[0096] S5. When the cleaning disc brush 30 finishes cleaning the steel strip, the scraper 37 and the rubber pad 38 fit tightly against the upper and lower surfaces of the steel strip to scrape off the residual rinsing liquid and dirt left during the cleaning process, so that it can be rinsed again in the spray neutralization treatment device 43 later.
