Description

Technical fields:

[0001] This invention relates to the field of metal passivation processing equipment technology, and more specifically to a cleaning device for passivation treatment of galvanized steel sheets. Background technology:

[0002] After processing, galvanized steel sheets and other metal parts require passivation treatment. Current passivation methods typically involve filling a passivation tank with a passivation solution, immersing the galvanized steel sheet in the solution for passivation. After a certain period of use, the passivation solution needs to be drained from the tank. After draining, a large amount of residue from the solution adheres to the inner wall of the tank, requiring manual cleaning. The current method involves manually holding a water gun to rinse the inner wall, which is labor-intensive. Furthermore, manual operation involves close proximity to the passivation tank, and the passivation solution poses certain health risks. Summary of the Invention:

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cleaning device for passivation treatment equipment of galvanized steel plates. After the solution in the passivation tank is discharged, it can automatically rinse the inner wall of the tank, so that a large amount of residual solution or residue on the inner wall surface is removed, so that only manual local cleaning is required afterward, which greatly reduces the amount of manual labor and reduces the harm to workers.

[0004] The solution of the present invention to the aforementioned technical problem is:

[0005] A cleaning device for passivation treatment of galvanized steel sheets includes a passivation water tank. Upper support frames are fixed to the outer walls of both the front and rear walls of the passivation water tank. Lifting mechanisms are fixed to the left and right sides of the upper support frames. Transverse beams are fixed to the outer walls of the lifting blocks of the two lifting mechanisms on the same side. Rotatable transverse pipes are installed on the opposing walls of the two transverse beams. Multiple water spray plates are connected to the side walls of the transverse pipes. Multiple water spray holes extending forward and backward are formed on the water spray plates and communicate with the transverse pipes. The water spray holes face the inner side wall of the corresponding side of the passivation water tank.

[0006] Fixed plates are fixed on the inner sidewalls of both ends of the transverse beam. A connecting shaft is formed in the middle of the left and right end plates of the transverse tube. The connecting shaft is movably connected to the corresponding fixed plate through bearings. A rotary servo motor is fixed on the outer sidewall of one of the fixed plates. The rotary servo motor drives the corresponding transverse tube to rotate.

[0007] The transverse tube has an axially extending axial hole formed in its middle section. Multiple axially extending insertion parts are fixed in the middle and at the edges of the outer side wall of the transverse tube. The internal cavity of the insertion part communicates with the corresponding transverse through groove formed on the outer side wall of the transverse tube. The transverse through groove communicates with the axial hole. The outer end face of the insertion part has an inwardly extending stepped through groove formed in its middle section. The stepped through groove communicates with the internal cavity. The outer end face of the spray plate has an extended fixing part formed. The extended fixing plate is inserted into the large-spacing through groove section at the outer end of the stepped through groove of the corresponding insertion part in the middle section. The middle section of the spray plate has multiple front-to-back extending spray holes. The spray holes communicate with the through groove formed in the middle section of the extended fixing plate. The through groove communicates with the internal cavity of the insertion part.

[0008] The side of the spray plate near the left or right side plate of the passivation water tank extends obliquely toward the left or right side plate of the passivation water tank, and the through hole at its side faces the inner wall of the left or right side plate of the passivation water tank.

[0009] The outer end of the stepped through groove of the plug part at the edge has a large-spacing through groove section with an extended locking part at the rear end of the obliquely extending edge spray plate. The edge spray plate has multiple spray holes that extend obliquely forward and backward, which communicate with the middle through groove of the extended locking part. The middle through groove communicates with the internal cavity of the corresponding plug part at the edge. The spray end of the spray holes of the edge spray plate faces the left or right side plate of the passivated water tank body.

[0010] A connecting block is fixed at the middle of the opposite wall of each of the two transverse beams. A connecting through hole extending to the left and right is formed in the middle of the connecting block. The middle of the transverse pipe is inserted into the connecting through hole. Multiple water inlet holes are formed on the outer wall of the middle of the transverse pipe. The water inlet holes communicate with the axial holes of the transverse pipe. A central annular groove is formed in the middle of the inner wall of the connecting through hole. The central annular groove communicates with the water inlet holes. A water inlet head is connected to the top surface of the connecting block. The water inlet head communicates with the vertical through hole formed in the middle of the top surface of the central annular groove.

[0011] The outstanding effects of this invention are:

[0012] After the solution in the passivation tank is discharged, it can automatically rinse the inner wall of the tank, removing a large amount of residual solution or residue from the inner wall surface. This allows for subsequent localized manual cleaning, greatly reducing the amount of manual labor and minimizing harm to workers. Attached image description:

[0021] See as Figures 1 to 8 As shown, a cleaning device for passivation treatment of galvanized steel sheets includes a passivation water tank 10. Upper support frames 20 are fixed to the outer walls of both the front and rear walls of the passivation water tank 10. Lifting mechanisms 30 are fixed to the left and right sides of the upper support frames 20. Each lifting mechanism 30 includes a vertical plate 32, which is fixed to two horizontal beams on the inner side of the upper support frame 20. Support plates 33 are fixed to the upper and lower parts of the inner wall of the vertical plate 32. The two ends of a vertical lifting screw 34 are movably connected to the two support plates 33 via bearings. A drive servo motor 35 is fixed to one of the support plates 33. The output shaft of the drive servo motor 35 is a splined shaft, which is inserted into the splined hole at one end of the corresponding vertical lifting screw 34 and drives the corresponding vertical lifting screw 34 to rotate. A lifting block 31 is screwed onto the vertical lifting screw 34.

[0022] The transverse beam 40 is fixed on the outer wall of the lifting block 31 of the two lifting mechanisms 30 on the same side. Rotatable transverse pipes 50 are installed on the opposite walls of the two transverse beams 40. Multiple water spray plates 60 are connected to the side wall of the transverse pipes 50. Multiple water spray holes extending forward and backward are formed on the water spray plates 60. The water spray holes are connected to the transverse pipes 50 and face the inner side wall of the corresponding side of the passivation water tank 10.

[0023] Furthermore, fixing plates 41 are fixed on the inner sidewalls of both ends of the transverse beam 40, and axially extending connecting shafts are formed in the middle of the left and right end plates of the transverse tube 50. The connecting shafts are movably connected to the corresponding fixing plates 41 through bearings. A rotary servo motor 42 is fixed on the outer sidewall of one of the fixing plates 41. The output shaft of the rotary servo motor 42 is a spline shaft, which is inserted into the spline hole of the corresponding connecting shaft. The rotary servo motor 42 drives the corresponding transverse tube 50 to rotate.

[0024] Furthermore, the transverse tube 50 has an axially extending axial hole 53 formed in the middle. The middle and edge of the outer wall of the transverse tube 50 are fixed with multiple axially extending insertion parts 54. The internal cavity of the insertion part 54 communicates with the corresponding transverse through groove 51 formed on the outer wall of the transverse tube 50. The transverse through groove 51 communicates with the axial hole 53. The middle of the outer end face of the insertion part 54 has an inwardly extending stepped through groove 541 formed. The stepped through groove 541 communicates with the internal cavity. The outer end face of the spray plate 60 has an extended fixing part 61 formed. The extended fixing plate 61 is inserted into the large-spacing through groove section at the outer end of the stepped through groove 541 of the corresponding insertion part 54 in the middle. The middle of the spray plate 60 has multiple front-to-back extending spray holes. The spray holes communicate with the through groove formed in the middle of the extended fixing plate 61. The through groove communicates with the internal cavity of the insertion part 54.

[0025] Furthermore, the side of the spray plate 60 near the left or right side plate of the passivation water tank 10 extends obliquely towards the left or right side plate of the passivation water tank 10, and the through hole at its side faces the inner wall of the left or right side plate of the passivation water tank 10.

[0026] Most of the spray holes on the spray plate 60 can rinse the inner wall of the front or rear side plate of the passivation water tank 10, while the spray holes on the outer side can rinse the inner wall of the left or right side plate of the passivation water tank 10.

[0027] Furthermore, the outer end of the stepped through groove 541 of the insertion part 54 at the edge has a large-spacing through groove section that holds an extended retaining part 71 at the rear end of the obliquely extending edge spray plate 70. The edge spray plate 70 has multiple obliquely extending spray holes formed on it, which communicate with the central through groove of the extended retaining part 71. The central through groove communicates with the internal cavity of the corresponding insertion part 54 at the edge. The spraying ends of the spray holes of the edge spray plate 70 face the left or right side plate of the passivation water tank 10. The inner wall surface of the left or right side plate of the passivation water tank 10 can be rinsed through the edge spray plate 70.

[0028] Furthermore, connecting blocks 80 are fixed to the middle of the opposite walls of the two transverse beams 40. A connecting through hole 81 extending laterally is formed in the middle of the connecting block 80. The middle of the transverse pipe 50 is inserted into the connecting through hole 81. Multiple water inlet holes 55 are formed on the outer wall of the middle of the transverse pipe 50, communicating with the axial hole 53 of the transverse pipe 50. A central annular groove 82 is formed in the middle of the inner wall of the connecting through hole 81, communicating with the water inlet hole 81. A water inlet head 83 is connected to the top surface of the connecting block 80, communicating with a vertical through hole formed in the middle of the top surface of the central annular groove 82. The water inlet head 83 is connected to a water inlet pipe.

[0029] Furthermore, an elastic sealing ring 1 is fitted on the inner wall at both ends of the connecting through hole 81, and multiple annular protrusions 2 are formed on the inner wall of the elastic sealing ring 1. The annular protrusions 2 are nested in the annular groove 56 formed on the outer wall of the middle part of the transverse tube 50.

[0030] The inner wall of the elastic sealing ring 1 is tightly attached to the outer wall of the middle part of the transverse tube 50. The elastic sealing ring 1 achieves a seal by rotating the transverse tube 50.

[0031] Furthermore, radially extending edges are formed on the outer walls of both ends of the elastic sealing ring 1. The inner radially extending edges are in close contact with the inner wall of the central annular groove 82, and the outer radially extending edges are in close contact with the outer wall surface of the connecting block 80.

[0032] The outer end of the stepped through-slot 541 has multiple vertical stepped through-holes 59 formed on both its top and bottom surfaces. The outer end of each vertical stepped through-hole 59 is a small-diameter hole, and the inner end is a large-diameter hole. A compression spring 591 and a limiting plate 592 are inserted into the large-diameter hole of the vertical stepped through-hole 59. A tapered positioning part is formed in the middle of the inner end of the limiting plate 592. This tapered positioning part is inserted into a positioning recess on the top or bottom surface of the corresponding extended fixing part 61 or extended locking part 71. One end of the compression spring 591 is attached to… The limiting plate 59 has a vertical rod formed in the middle of its outer end face. The vertical rod is inserted into the compression spring 591. The outer end of the vertical rod extends out of the corresponding vertical stepped through hole 59 and is fixed with an adsorption plate. The outer diameter of the limiting plate 591 is larger than the inner diameter of the small diameter hole of the vertical stepped through hole 59. The top and bottom surfaces of the corresponding insertion part 54 are fixed or formed with horizontal extension plates. The inner end face of the horizontal extension plate is fixed with a permanent magnet block 9. The permanent magnet block 9 corresponds to the corresponding adsorption plate.

[0033] In this embodiment, after the solution in the passivation water tank 10 is discharged, the control valve of the water inlet pipe connected to the water inlet head 83 can be opened to allow water to flow. The water is discharged from all the spray holes to spray and rinse the corresponding inner wall of the passivation water tank 10. The horizontal pipe 50 is rotated by the operation of the rotary servo motor 42, thereby changing the spray angle of the spray holes and rinsing the entire surface of the corresponding inner wall of the passivation water tank 10. The horizontal pipe 50 can be adjusted in height by the synchronous operation of the two drive servo motors 35 of the same upper support frame 20.

[0034] After rinsing is completed, all components stop operating, and then manual inspection can be carried out. Any parts that were not rinsed can be manually rinsed. Generally, there will only be residue in some corners. Manual rinsing is very fast. This embodiment greatly reduces the amount of manual labor and reduces the harm to the human body.

[0035] In this embodiment, when the side spray plate 70 or spray plate 60 needs to be cleaned or replaced, simply pull the corresponding adsorption plate outward so that it is in close contact with the corresponding permanent magnet block 9 to achieve adsorption. At this time, the conical positioning part moves out of the positioning recess on the top or bottom surface of the extended fixing part 61 or the extended locking part 71. Then, the side spray plate 70 or spray plate 60 can be pulled outward by force to remove it and disassemble it. The disassembly is convenient.
