[0002] Dacromet coating passivation equipment is a surface treatment equipment, mainly used to form a protective Dacromet coating on the metal surface to improve the corrosion resistance of metal parts. Dacromet coating is an inorganic coating, usually composed of inorganic salts of metals such as zinc, aluminum, iron and chromium, which protects metal materials by forming an anti-corrosion protective layer on the metal surface. This coating can provide excellent corrosion resistance and is widely used in marine environments, high humidity environments and chemical corrosion environments.

[0003] In the prior art, a Chinese patent document with publication number CN116463618B proposes a Dacromet coating passivation device that uses the interaction between electromagnetics and springs to separate gas and liquid and pressurize the passivation liquid, thereby increasing the Dacromet coating passivation reaction rate, using a contact conductive short circuit to achieve automatic control of the unsealing state inside the device, using the floating characteristics to achieve liquid level feedback and self-identification, and using a high hydraulic pressure and a slowly rotating circulating liquid flow to significantly improve the metal parts coating passivation efficiency, and ensure that the passivation coating can be stably attached to the metal parts surface, but consistent with the traditional method, the traditional equipment usually does not have the function of pre-treating the material, such as cleaning, removing oil stains and oxides, etc. These pre-treatment steps are not necessary to ensure that the coating liquid can It is crucial to be able to effectively adhere to the surface of the material, and traditional passivation equipment usually clamps or places the material to be processed in a fixed position, and then places the entire material into the coating box for processing. This operation mode causes the processed material to be unable to be fully exposed to the passivation liquid during the coating process, thereby producing untreated or under-treated areas, affecting the uniformity and quality of the coating, and the position of clamping or fixing the material will cause dead corners or difficult-to-reach areas in the processed material. These areas cannot be effectively treated, resulting in the coating liquid being unable to cover every part, affecting the uniformity and consistency of the treatment.

[0018] Beneficial effects of the present invention:

[0019] 1. This Dacromet coating passivation equipment, by providing a flip module on the pretreatment component and a fishtail-shaped side, can increase the stability of the flip plate, making it more stable and reliable during operation, and the rolling of the rotating roller can fully mix the liquid and material in the pickling tank, thereby enhancing the contact and reaction between the pickling liquid and the material, improving the pickling effect, avoiding the situation of insufficient or excessive local pickling, and improving the uniformity and consistency of the treatment. Secondly, the rolling of the rotating roller can help balance the center of gravity of the material during the flipping process, reduce the shaking or deviation of the flip plate due to the unstable center of gravity, thereby increasing the stability of the flipping, and can absorb part of the vibration caused by the inertia of the material or the unstable movement of the flip plate. Energy is generated, thereby reducing the vibration of the system and making the flipping process smoother. When the flip plate flips toward the direction close to the coating component, the cleaned material flips forward and is assisted by the convex arc surfaces of the flip blocks to flip to one side and can move forward. When the flip plate flips toward the direction away from the coating component, the cleaned material flips backward and is blocked by the concave arc surfaces of the flip blocks. It can only flip locally and will not move backward. In this way, the cleaned material will be close to the coating component. The advantage of this is that the pickling liquid and the material can be stirred during the flipping process, which increases the flushing and cleaning effect of the pickling liquid on the material surface, ensures the uniformity and thoroughness of the pickling process, and allows the pickling liquid to more fully contact the material surface.

[0020] 2. This Dacromet coating passivation equipment has a baffle and three slides of different specifications on the coating assembly. The vertical tilted installation of the baffle and the staggered tilted arrangement of the three fixed slides of different specifications form a multi-layer inclined surface inside the coating box. When the material to be coated enters the coating box, it is driven to move downward by the three fixed slides of different specifications. The staggered slides can make the coated material move downward back and forth inside the coating box for coating. The staggered tilted arrangement and gradually decreasing width of the three fixed slides can prevent the coating liquid from accumulating in the box, avoid uneven coating thickness or accumulation, and ensure uniform distribution of the coating on the surface of the coated material. Uniform coating and uniformity of the coating surface can improve the adhesion of the coating, make it more firmly adhere to the surface of the coated material, and reduce the possibility of coating peeling.

[0021] 3. This kind of Dacromet coating passivation equipment has three corresponding movable slides on three fixed slides, and a turning column is arranged on the other side of the three movable slides. When the coated material passes through the bottom of the first movable slide and falls to the upper part of the second fixed slide, the rear slide is similarly turned over and dropped by the turning column, so that the coated material and the contact surface of the slide are turned over and replaced, and no dead corners of coating are generated, which can ensure that the coating liquid covers every corner of the coated material and avoids the generation of coating dead corners, thereby improving the uniformity and integrity of the coating. In addition, in the turning process, the three movable slides can be pushed to slide inside the corresponding three fixed slides according to the size of the coated material, and there will be no accumulation caused by different material sizes, which can adapt to materials of various specifications.

[0022] 4. This type of Dacromet coating passivation equipment is equipped with a liquid outlet network and a collection box. The flowing coating liquid will enter the interior of the collection water tank at the position of the liquid outlet network, and the coated material continues to move forward and is supported by the liquid outlet network to continue to move to one side. The coated material is guided into the discharge port through the guide block. The guide block is located on one side of the discharge trough, which can ensure the smooth flow of the material, reduce resistance and friction, and improve the efficiency and fluency of the discharge. The liquid outlet network and the water inlet network can collect the coating liquid flowing out of the discharge trough, which is helpful for the subsequent recovery and reuse of the coating liquid. The reserved openings on the top of the partition and the top surface of the collection water tank can be connected to an external water pump to realize the reflux of the coating liquid, save resources and improve the coating efficiency.

[0038] like Figures 1 to 10 As shown, the Dacromet coating passivation equipment includes a mounting plate 1, two fixed plates 2 are fixedly installed on one side of the top of the mounting plate 1, and a pretreatment component is rotatably installed on the top of the two fixed plates 2. The pretreatment component includes a flip module and a cleaning module, and the pretreatment component is used to pickle the required passivation material; a coating component is arranged on one side of the mounting plate 1, and the coating component is used to perform surface treatment on the required passivation material, and the coating component includes a coating box 17, and a feeding port 18 for feeding is opened on the top of the coating box 17, and a discharge plate 35 for discharging is arranged on one side of the bottom of the coating box 17; the flip module includes a flip plate 3 rotatably installed above the two fixed plates 2, and a pickling tank 6 for placing the required passivation material is opened on the top surface of the flip plate 3, and a fixed rod 4 is fixedly installed on the other side of the mounting plate 1, and a first cylinder 5 is rotatably installed on the top of the fixed rod 4. The telescopic end of the cylinder 5 is rotatably connected to the other side of the bottom surface of the flip plate 3; the cleaning module includes a plurality of positioning frames 13 mounted on the flip plate 3, the plurality of positioning frames 13 are arranged in a door-shaped frame, the tops of the plurality of positioning frames 13 are provided with spray pipes 14, the bottom surfaces of the spray pipes 14 are equidistantly provided with a plurality of spray heads, one side of the plurality of spray pipes 14 is penetrated by the positioning frames 13, and one side of the plurality of positioning frames 13 is connected with a connecting pipe, a micro-boosting pump 12 is arranged between the plurality of positioning frames 13 and the connecting pipe, and an external pipe 11 is also arranged at the bottom of the connecting pipe, wherein two second cylinders 15 are further arranged between the mounting plate 1 and the coating assembly, the top ends of the two second cylinders 15 are fixedly connected with guide plates 16, and the guide plates 16 are arranged with an inclined surface on one side close to the coating assembly, so as to guide the pickled material inside the flip plate 3 into the coating assembly;

[0039] First, the material to be passivated is placed on the top surface of the flip module and placed in the pickling tank 6. The pickling module in the pretreatment component is turned on, and the micro-boosting pump 12 in the cleaning module is started to ensure that the acid can fully cover the surface of the material. At this time, the spray pipe 14 in the pickling module sprays the acid and evenly covers the surface of the material. At the same time, the first cylinder 5 controls the inclination of the flip plate 3 so that the material in the pickling tank 6 is fully immersed in the acid to ensure uniform pickling treatment. After the pickling is completed, the pickling module is closed and the material in the flip plate 3 is guided to the coating component. During the guiding process, the height of the guide plate 16 is controlled by the second cylinder 15 to guide the material in the pretreatment component to the inside of the feed port 18. The coating box 17 in the coating component is started to apply the required coating on the surface of the material. The coated material flows out from the discharge plate 35. After the coating is completed, the treated material can be taken out. Through pickling and coating treatment, the corrosion resistance of the material is improved, the uniformity and consistency of the coating are ensured, and the production efficiency is improved and the cost is saved.

[0040] like Figure 1 , Figure 4 As shown, the flip plate 3 is arranged in a fishtail shape on one side away from the coating assembly, and two electric telescopic rods 7 are fixedly installed below the fishtail-shaped side of the flip plate 3. The output ends of the two electric telescopic rods 7 are fixedly connected to a limit plate 8, and the limit plate 8 is arranged through the flip plate 3. The top surface of the flip plate 3 is provided with a rotating roller 9, which is arranged in a hollow tube shape and is used to roll above the pickling tank 6;

[0041] The advantage of doing this is that, by setting a fishtail-shaped side, the stability of the flip plate 3 can be increased, making it more stable and reliable during operation, and the rolling of the rotating roller 9 can make the liquid and material in the pickling tank 6 fully mixed, thereby enhancing the contact and reaction between the pickling liquid and the material, improving the pickling effect, avoiding local insufficient or excessive pickling, and improving the uniformity and consistency of the treatment. Secondly, the rolling of the rotating roller 9 can help balance the center of gravity of the material during the flipping process, reduce the shaking or deviation of the flip plate 3 due to the unstable center of gravity, thereby increasing the stability of the flipping, and can absorb part of the vibration energy generated by the inertia of the material or the unstable movement of the flip plate 3, thereby reducing the vibration of the system and making the flipping process smoother. At the same time, an electric telescopic rod 7 is provided on the fishtail-shaped side of the flip plate 3 to control the movement of the limit plate 8, limit or remove the rotating roller 9, and increase operability.

[0042] like Figure 4 As shown, a plurality of flip blocks 10 are arranged equidistantly inside the pickling tank 6. The side of the flip block 10 away from the coating component is in an outward convex arc shape, and the side of the flip block 10 close to the coating component is in an inward concave arc shape;

[0043] When the flip plate 3 flips toward the direction close to the coating component, the cleaned material flips forward and is assisted by the convex arc surfaces of the flip blocks 10 to flip to one side and can move forward. When the flip plate 3 flips toward the direction away from the coating component, the cleaned material flips backward and is blocked by the concave arc surfaces of the flip blocks 10. It can only flip locally and will not move backward. In this way, the cleaned material will be close to the coating component. The advantage of this is that it can stir the pickling liquid and the material during the flipping process, increase the flushing and cleaning effect of the pickling liquid on the material surface, ensure the uniformity and thoroughness of the pickling process, and enable the pickling liquid to more fully contact the material surface, thereby improving the pickling efficiency, accelerating the pickling process, reducing the processing time, and improving production efficiency. At the same time, the convex and concave surfaces of the flip blocks 10 can cause the pickling liquid to form a vortex flow inside the pickling tank 6, so that the pickling liquid can evenly cover the material surface, ensuring that the material is evenly pickled during the pickling process.

[0044] like Figure 5 , Figure 6 , Figure 8 As shown, a partition 19 is vertically and obliquely installed inside the coating box 17, and a first fixed slide 20, a second fixed slide 22 and a third fixed slide 24 are arranged in sequence from top to bottom between the inside of the coating box 17 and the partition 19, and the first fixed slide 20, the second fixed slide 22 and the third fixed slide 24 are all arranged obliquely from one side of the inside of the coating box 17 to the other side, and the first fixed slide 20, the second fixed slide 22 and the third fixed slide 24 are arranged in a staggered oblique manner, and the widths of the first fixed slide 20, the second fixed slide 22 and the third fixed slide 24 decrease in sequence following the degree of inclination of the partition 19;

[0045] The advantage of doing this is that the vertically inclined installation of the partition 19 and the staggered inclined setting of three fixed slides of different specifications form a multi-layer inclined surface inside the coating box 17. When the material to be coated enters the coating box 17, it is driven downward by the three fixed slides of different specifications. The staggered slides can make the coated material move downward back and forth inside the coating box 17 for coating, and the staggered inclined setting and gradually decreasing width of the three fixed slides can prevent the coating liquid from accumulating in the box, avoid uneven coating thickness or accumulation, and ensure the uniform distribution of the coating on the surface of the coated material. Uniform coating and uniformity of the coating surface can improve the adhesion of the coating, make it more firmly adhere to the surface of the coated material, and reduce the possibility of coating peeling.

[0046] like Figure 6 , Fig. 9As shown, the interiors of the first fixed slide 20, the second fixed slide 22 and the third fixed slide 24 are all hollow, and the first movable slide 21, the second movable slide 23 and the third movable slide 25 are movably installed in the interiors of the first fixed slide 20, the second fixed slide 22 and the third fixed slide 24, respectively. A return spring 36 is arranged between the first fixed slide 20, the second fixed slide 22 and the third fixed slide 24 and the first movable slide 21, the second movable slide 23 and the third movable slide 25, respectively, and the top surfaces of the first fixed slide 20, the second fixed slide 22 and the third fixed slide 24 and the first movable slide 21, the second movable slide 23 and the third movable slide 25 are respectively arranged in an arc shape with high sides and low middle, and the other ends of the first movable slide 21, the second movable slide 23 and the third movable slide 25 are fixedly installed with a flip column 26, and a plurality of flip columns 26 are arranged to have the same arc as the first movable slide 21, the second movable slide 23 and the third movable slide 25;

[0047] The arc-shaped design of the slide plate with high sides and low middle helps the coating liquid to form a more uniform liquid flow inside the coating box 17, thereby optimizing the coating effect and ensuring uniform coverage of the coating liquid on the surface of the coated material. When the coated material passes the bottom of the first movable slide plate 21 and falls to the upper part of the second fixed slide plate 22, the rear slide plate is similar. Through the action of the flip column 26, the coated material is flipped and dropped, which will cause the coated material and the contact surface of the slide plate to be flipped and replaced, and no dead corners of coating will be generated. It can ensure that the coating liquid covers every corner of the coated material, avoiding the generation of coating dead corners, thereby improving the uniformity and integrity of the coating. In addition, during the flipping process, the three movable slides can be pushed to slide inside the corresponding three fixed slide plates according to the size of the coated material, and there will be no accumulation caused by different material sizes, which can adapt to materials of various specifications.

[0048] like Figure 6 , Figure 7 , Fig.10 As shown, a guide groove 27 is provided between the bottom of the partition 19 and the coating box 17, and a collecting water tank 32 is also provided on one side of the inner bottom of the coating box 17. A collecting water tank 33 adapted to the guide groove 27 is provided on the top of one side of the collecting water tank 32. Both the guide groove 27 and the collecting water tank 33 are arranged in a semicircular trumpet shape;

[0049] After the coated material inside the coating box 17 reaches the inside of the guide groove 27, the material and the coating liquid flow to one side. During the flow, the coating liquid is collected by the collecting trough 33 on the collecting water tank 32. The horn-shaped setting of the guide groove 27 and the collecting trough 33 and the gradually expanding collection area helps to avoid the coating liquid from remaining in the trough, ensuring that the coating material can flow smoothly into the collecting trough 33, thereby improving the efficiency and quality of the coating process.

[0050] like Fig.10 As shown, a liquid outlet net 28 is provided on one side of the guide groove 27, a material outlet trough 29 is provided on the other side of the guide groove 27, a guide block 30 is provided on one side of the material outlet trough 29, the guide block 30 is arranged in a triangular shape, and the long side of the guide block 30 is arranged in an arc shape, a material outlet 31 is also provided on one side of the material outlet trough 29, the material outlet 31 is adapted to a material outlet plate 35, the material outlet plate 35 is arranged in a slope shape, and the top surface of the material outlet plate 35 is arranged in an inwardly concave arc shape, a water inlet net with a mesh diameter twice that of the liquid outlet net 28 is provided above the collecting water trough 33, an auxiliary groove 34 adapted to the material outlet trough 29 is provided on one side of the collecting water trough 33, and reserved openings are provided on the top of the partition plate 19 and the top surface of the collecting water tank 32 for connecting an external water pump for reflux use;

[0051] The advantage of this is that the flowing coating liquid will enter the collecting water tank 32 at the position of the liquid outlet net 28, and the coated material will continue to move forward and continue to move to one side supported by the liquid outlet net 28, and the coated material will be guided into the discharge port 31 through the guidance of the guide block 30. The guide block 30 is located on one side of the discharge trough 29. Its triangular design and arc-shaped long side help guide the coated material to move toward the discharge port 31, which can ensure the smooth flow of the material, reduce resistance and friction, and improve the efficiency and fluency of the discharge, and then pass The material is discharged through the discharge plate 35. The sloped design and the concave arc-shaped setting of the top surface of the discharge plate 35 help the coated material to flow out smoothly from the discharge port 31, avoid material retention and blockage, ensure the smoothness and stability of the discharge, and thus improve production efficiency. The liquid outlet network 28 and the water inlet network can collect the coating liquid flowing out of the discharge trough 29, which is helpful for the subsequent recovery and reuse of the coating liquid. The reserved openings on the top of the partition 19 and the top surface of the collection water tank 32 can be connected to an external water pump to realize the reflux of the coating liquid, save resources and improve coating efficiency.
