Description

Technical Field

[0001] This utility model relates to the field of marine plate processing technology, and in particular to a plate pickling and passivation treatment device. Background Technology

[0002] The marine environment is extremely harsh, characterized by high salinity, high humidity, and high corrosion. Shipboard plates require pickling and passivation treatment. The purpose of pickling is to remove the oxide scale from the surface of the plate, while the purpose of passivation is to form a dense, stable, and chromium-rich chromium oxide protective film on the surface of the stainless steel plate, thereby improving the corrosion resistance of the plate surface and welded joints.

[0003] The existing pickling and passivation process involves manually applying pickling paste to the surface of the plate and welded areas, then scraping off most of the reacted pickling paste and cleaning before applying passivation solution. The chemical reagents used for pickling and passivation are generally strong acids, which are highly corrosive and toxic. During this process, workers need to wear protective gloves and clothing, posing operational safety risks. Furthermore, each plate needs to be processed individually, impacting production capacity. Utility Model Content

[0004] The purpose of this invention is to provide a plate pickling and passivation treatment device that can replace manual operation and improve the plate processing speed.

[0005] To achieve the above-mentioned utility model objectives, this utility model provides a plate pickling and passivation treatment device, including a pickling tank, a cleaning tank, a passivation tank, a lifting mechanism, a material transfer mechanism, and a material placement frame;

[0006] The pickling tank, the cleaning tank, and the passivation tank are located side by side below the material transfer mechanism;

[0007] The lifting mechanism includes a top plate, a cylinder, a connecting plate, and a hanging rope. The cylinder is connected to the connecting plate through the top plate, and the hanging rope is connected to the bottom of the connecting plate and to the material placement frame. A connecting block is provided on the top of the top plate, and the connecting block is connected to the material transfer mechanism.

[0008] The material placement frame has a mesh structure.

[0009] Preferably, a guide rod is provided between the top plate and the connecting plate.

[0010] As a further improvement of the utility model, the material placement frame is provided with a connecting ring, and the end of the hanging rope is provided with a hook, which hooks onto the connecting ring.

[0011] Furthermore, the connecting ring and the side of the material placement frame are provided with reinforcing triangular strips.

[0012] As a further improvement to the utility model, both the material placement frame and the hanging rope are made of inert material.

[0013] As a further improvement of the utility model, the connecting block is provided with a sensing rod, the material transfer mechanism is connected to a mounting frame, the mounting frame is provided with three sensing elements, the positions of the three sensing elements are respectively adapted to the positions of the pickling tank, the cleaning tank and the passivation tank, and the position of the sensing rod is adapted to the position of the sensing elements.

[0014] As a further improvement of the utility model, a grid floor is provided below the pickling tank, the cleaning tank, and the passivation tank.

[0015] This utility model discloses a plate pickling and passivation treatment device. The plates to be treated are laid flat one by one in a placement frame. A transfer mechanism moves the placement frame connected to it above the pickling tank. A cylinder controls the placement frame to descend, immersing the plates in the pickling solution in the pickling tank. After a period of time (according to the pickling standards of various plates), the cylinder controls the placement frame to rise, lifting the plates out of the pickling solution and pausing them briefly above the pickling tank to allow most of the acid remaining on the plates to flow back into the tank. Subsequently, the transfer mechanism moves the plates in the placement frame above a cleaning tank, and the cylinder immerses the plates in the cleaning tank for cleaning. The cleaning tank can be a flowing water rinsing tank to completely remove acidic residues and dissolved metal ions from the plate surface, preventing yellow spots from appearing on the plate surface. Finally, the cleaned plates are transferred to a passivation tank via the transfer mechanism, where they are immersed in a passivation solution for passivation treatment.

[0016] The advantages of this plate pickling and passivation treatment device compared with the prior art are as follows:

[0017] (1) The mesh structure of the material placement frame can maximize the contact area between the plate and the treatment liquid, and when the plate is suspended, the treatment liquid can quickly fall from the mesh of the material placement frame, reducing liquid residue on the plate.

[0018] (2) The plate body is pickled, washed and passivated through the lifting mechanism and the material transfer mechanism, which facilitates batch processing, reduces the risk of direct contact between manual hands and processing liquid, and improves processing efficiency.

[0021] Figure 3 This is a schematic diagram of the lifting mechanism. Detailed Implementation

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-2 As shown, the present invention provides a plate pickling and passivation treatment device, which includes a pickling tank 1, a cleaning tank 2, a passivation tank 3, a lifting mechanism 4, a material transfer mechanism 5, and a material placement frame 6.

[0024] Pickling tank 1, cleaning tank 2, and passivation tank 3 are located side by side below the material transfer mechanism 5;

[0025] like Figure 3 As shown, the lifting mechanism 4 includes a top plate 41, a cylinder 42, a connecting plate 43, and a hanging rope 44. The cylinder 42 is connected to the connecting plate 43 through the top plate 41. The hanging rope 44 is connected to the bottom of the connecting plate 43 and is connected to the material placement frame 6. A connecting block 47 is provided on the top of the top plate 41 and is connected to the material transfer mechanism 5.

[0026] The material placement frame 6 has a mesh structure.

[0027] This utility model discloses a plate pickling and passivation treatment device. The plates to be treated are laid flat one by one in a placement frame 6. A transfer mechanism 5 moves the placement frame 6 above the pickling tank 1. A cylinder 42 controls the placement frame 6 to descend, immersing the plates in the pickling solution in the pickling tank 1. After a period of time (according to the pickling standards of various plates), the cylinder 42 controls the placement frame 6 to rise, lifting the plates out of the pickling solution and pausing them briefly above the pickling tank 1 to allow most of the acid remaining on the plates to flow back into the tank. Subsequently, the transfer mechanism 5 moves the plates in the placement frame 6 above a cleaning tank 2, and the cylinder 42 immerses the plates in the cleaning tank 2 for cleaning. The cleaning tank 2 can be a flowing water rinsing tank to completely remove acidic residues and dissolved metal ions from the plate surface, preventing yellow spots from appearing on the plate surface. Finally, the cleaned plates are transferred to a passivation tank 3 via the transfer mechanism 5, where they are immersed in a passivation solution for passivation treatment.

[0028] The lifting mechanism controls the lifting of the material box 6. A guide rod 46 is provided between the top plate 41 and the connecting plate 43. The connecting plate 43 lifts and lowers along the guide rod 46 to reduce the shaking of the material box 6 during lifting and lowering and to prevent the plates from colliding with each other.

[0029] The material storage frame 6 is equipped with a connecting ring 61, and the end of the hanging rope 44 is equipped with a hook 45, which hooks the connecting ring 61. The separate structure of the hanging rope 44 and the material storage frame 6 makes it convenient to replace material storage frames 6 of different sizes.

[0030] The connecting ring 61 and the side of the material frame 6 are provided with reinforcing triangular strips 62. The reinforcing triangular strips 62 can strengthen the connection between the material frame 6 and the hanging rope 44 and reduce the shaking of the material frame 6 when it moves.

[0031] Both the material placement frame 6 and the hanging rope 44 are made of inert material, such as polypropylene. Since the pickling and passivation treatment solutions are both highly corrosive liquids with strong acids, the inert material can prevent damage to the material placement frame 6 and the hanging rope 44.

[0032] The material transfer mechanism 5 can be an existing sprocket and chain drive assembly. A motor drives the sprocket to rotate, thereby moving the connecting block 47 connected to the chain. The connecting block 47 is equipped with a sensing rod 48. The material transfer mechanism 5 is connected to a mounting frame 51, which has three sensors 52. The positions of the three sensors 52 are respectively adapted to the positions of the pickling tank 1, the cleaning tank 2, and the passivation tank 3. The position of the sensing rod 48 is adapted to the position of the sensing elements 52. The sensing elements 52 can be existing photoelectric sensors. When the position of the sensing rod 48 is sensed, the photoelectric sensor converts the sensed light signal into an electrical signal and transmits the electrical signal to the terminal control box. The control box, based on the signal, links with the motor of the material transfer mechanism 5, enabling more precise control of the material transfer position of the material transfer mechanism 5.

[0033] A grid floor 7 is installed below the pickling tank 1, the cleaning tank 2, and the passivation tank 3. A wastewater tank can be installed below the grid floor 7. During the process of the material transfer mechanism 5 transferring the plate from each tank, the liquid falls onto the grid floor 7. The waste liquid falls from the grid floor 7 into the wastewater tank below, and the waste liquid is collected and treated in a unified manner to avoid polluting the environment.
