Description

Technical Field

[0001] This utility model relates to the technical field of chemical method metal material cleaning and degreasing production line. Background Technology

[0002] Pickling and phosphating are key processes in metal surface treatment, primarily used to improve the durability and coating effect of metal materials. Pickling and phosphating production lines are industrial production lines used for surface treatment of metal materials, mainly for removing rust, oxide layers, and forming phosphating films on metal surfaces such as steel, aluminum, and zinc. This improves the corrosion resistance of metal materials and increases coating adhesion.

[0003] A pickling and phosphating production line mainly includes a pickling process area, a washing process area, a phosphating process area, and a washing and drying process area. To meet production capacity requirements, enterprises may need to have several of each process station. In traditional production methods, to facilitate the configuration of metal material hoisting equipment, the workstations are usually linearly distributed. This type of production line often has a large overall length, requiring not only a very long equipment storage space but also being detrimental to the operation and maintenance of the production line. Therefore, some production lines are designed as loop production lines. For example, Chinese utility model patent CN201214683Y discloses a loop track for a pickling and phosphating production line to achieve the goal of minimizing the occupancy rate of the production space. In actual production, it has been found that regardless of whether it is pickling, phosphate washing, or a water washing process between the two, the metal materials being hoisted are not dried after washing. After the metal materials are lifted from the pickling tank, there will inevitably be residual chemicals on the outer surface. This problem is more prominent when the production pace is fast. The residual chemicals will flow or drip due to gravity during the hoisting of the metal materials. When the metal materials are hoisted and reach the bends and loops, the hoisted metal materials will be thrown outward due to centrifugal force, which not only easily causes collisions, but also throws the acid solution onto the processing site. In addition, the distance and angle of the chemical solution being thrown outward are individually related to the shape and tonnage of the metal materials themselves, which is difficult to control and collect, and poses a serious safety hazard. Utility Model Content

[0004] In view of at least one of the above technical problems, this utility model provides a pickling and phosphating production line, which separates the pickling process tank and the phosphating process tank, and connects the two with a rotating area. The rotating area is set as a water washing process area, and the track stroke is designed with a multi-zigzag structure, thereby overcoming the technical problem of centrifugal force when lifting metal materials at the arc rotation point. The specific technical solution is as follows:

[0005] A pickling and phosphating production line, comprising:

[0006] The pickling process chamber includes several pickling tanks arranged in a straight line. A water-sealed feed tank is located at the outer end of the pickling process chamber, and the feed area is located outside the water-sealed feed tank. The inner end of the pickling process chamber connects to the washing process chamber, which in turn connects to the phosphating process chamber. The phosphating process chamber includes several phosphating tanks arranged in a straight line. The outer end of the phosphating process chamber connects to the washing chamber, which in turn connects to the saponification chamber. A drying and discharge area is located outside the saponification chamber.

[0007] The center connection lines of all pickling tank layouts and all phosphating tank layouts are not collinear.

[0008] Linear track I is installed above the water-sealed feed tank and pickling tank along the feeding area; linear track II is installed above the water washing process chamber; and linear track III is installed above the phosphating tank, water washing chamber, saponification chamber, and drying discharge area. Linear track I, linear track II, and linear track III are of the same specifications and height, are connected, and are equipped with at least one rail-mounted crane.

[0009] In some embodiments of this disclosure, the water-sealed feed tank includes a water tank, the inner end of which is located in the pickling process chamber, a gas isolation plate is provided on the upper part of the water tank, and a material translation device is provided on the lower part of the water tank.

[0010] In some embodiments of this disclosure, the cargo translation device includes an associated bidirectional traction assembly and a cargo-carrying trolley.

[0011] In some embodiments of this disclosure, the center connecting lines of all pickling tank layouts and all phosphating tank layouts are arranged parallel to each other and on the same side of the washing process chamber.

[0012] In some embodiments of this disclosure, the washing process chamber includes an immersion tank and a rinsing tank, the layout axis of the immersion tank and the layout axis of the nearest pickling tank are collinear, and the layout axis of the rinsing tank and the nearest phosphating tank are collinear.

[0013] In some embodiments of this disclosure, the center connecting line of the immersion tank and rinsing tank layout is perpendicular to the center connecting line of all pickling tank layouts.

[0014] In some embodiments of this disclosure, the linear track II is disposed above the layout axis of the immersion tank and the rinsing tank.

[0015] In some embodiments of this disclosure, a guide rail is provided between the feeding area and the drying discharge area.

[0016] In some embodiments of this disclosure, the guide rail has the same specifications and height as the linear track I and is connected to it.

[0017] In some embodiments of this disclosure, each of the linear track I, linear track II, linear track III, and guide rail is equipped with at least one rail hoisting vehicle.

[0018] Compared with existing technologies, the above-mentioned pickling and phosphating production line has the following advantages:

[0019] By separating the pickling process chamber and the phosphating process chamber from each other and connecting them with a rotating area, which is set as the water washing process area, and designing the track travel as a multi-fold line structure, we can avoid the long layout of the entire production line and avoid the technical problem of centrifugal force when hoisting metal materials on the production line at the arc turning point.

[0020] The multi-zigzag design involves straight sections of track where liquid residue may remain after washing, all of which pass above the liquid pool. This facilitates the recycling of chemicals or water after metal material treatment and helps maintain the cleanliness of the work site.

[0021] Separating the pickling process room and the phosphating process room facilitates the installation of corresponding feeding and discharging pipelines, chemical tanks, and liquid pumps. Attached Figure Description

Detailed Implementation

[0025] To better understand the purpose, structure, and function of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below. It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application. The terms "comprising" and "equivalent to," and any variations thereof, are open-ended and intended to cover non-exclusive inclusion.

[0026] As shown in the attached diagram. Figures 1 to 2 As shown, an acid pickling and phosphating production line is designed, comprising:

[0027] The pickling process chamber includes several pickling tanks 1 arranged in a straight line. A water-sealed feed tank 2 is located at the outer end of the pickling process chamber, and the feed area 3 is located outside the water-sealed feed tank 2. Figure 1 In the middle, it can be seen on the right side of the water-sealed feed tank 2. The word "outer" here is only for the convenience of description and is not a functional limitation.

[0028] The pickling process chamber is connected to the washing process chamber 4 at its inner end. The washing process chamber 4 is connected to the phosphating process chamber. The phosphating process chamber includes several phosphating tanks 5 arranged in a straight line. The washing process chamber 6 is connected to the washing process chamber 6 at its outer end. The saponification chamber 7 is connected to the saponification chamber 7 at its outer end. A drying and discharge area 8 is provided on the outside of the saponification chamber 7.

[0029] The center connection lines of all pickling tank layouts and all phosphating tank layouts are not collinear.

[0030] A straight track I91 is set above the feeding area 3, the water-sealed feeding pool 2 and the pickling pool 1; a straight track II92 is set above the water washing process chamber 4; and a straight track III93 is set above the phosphating pool 5, the water washing chamber 6, the saponification chamber 7 and the drying and discharging area 8.

[0031] Linear track I 91, linear track II 92 and linear track III 93 are identical in specifications and height, connected and equipped with at least one rail hoist 94.

[0032] By separating the pickling and phosphating process rooms, which are not arranged in a coaxial manner, it is easier to lay out the corresponding feeding and discharging pipelines, chemical tanks, and liquid pumps. The two are connected by a rotary area, which is set as the water washing process area 4. The track travel is designed with a multi-zigzag structure, which can avoid the long layout of the entire production line and avoid the technical problem of centrifugal force when hoisting metal materials at the curved turning point on the production line. The multi-zigzag design involves straight sections of track where liquid residue remains on the walls after the metal materials are washed with liquid. The transport trajectory passes above the liquid tank, which not only facilitates the recycling and treatment of the chemical solution or water after the metal materials are treated, but also helps to maintain the cleanliness of the work site.

[0033] The above embodiments illustrate three examples of implementing the aforementioned technical solutions. The term "embodiment" as used herein means that a specific feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of this application. The appearance of this phrase in various locations within the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.

[0034] Example 1 discloses an acid pickling and phosphating production line, comprising:

[0035] The pickling process chamber has an airtight structure and includes several pickling tanks 1 arranged in a straight line (seven in this embodiment). The concentration of the chemical solution in each pickling tank 1 can be adjusted as needed to ensure the pickling effect. A water-sealed feed tank 2 is provided at the outer end of the pickling process chamber. The water-sealed feed tank 2 includes a water pool, with its inner end located inside the pickling process chamber. A gas isolation plate is provided above the water pool, and a material transfer device is provided below the water pool. In this embodiment, the material transfer device includes a bidirectional traction component and a trolley. During use, water is injected into the water pool to ensure that the water level fully contacts the surface of the tank. The lower end of the gas isolation plate separates the water tank into two spaces. Keeping the bottom of the water tank unobstructed allows the metal material to move between the left and right sides of the water tank under the gas isolation plate. The water in the water tank achieves a water seal effect, preventing the acidic vapors of pickling tank 1 from evaporating into the working space. The loading trolley is moved outward to the outside of the gas isolation plate, and the metal material to be processed is placed on the loading trolley in the water-sealed feeding tank 2, ensuring that the metal material is submerged in the water. The loading trolley is then moved to the side where pickling tank 1 is located to achieve sealed feeding. Moving the material to the outside of the water-sealed feeding tank 2 is the feeding area 3.

[0036] The pickling process chamber is airtightly connected to the washing process chamber 4, and the washing process chamber 4 is airtightly connected to the phosphating process chamber. The phosphating process chamber includes several phosphating tanks 5 arranged in a straight line. The concentration of the chemical solution in each phosphating tank 5 can be set as needed. The outer end of the phosphating process chamber is connected to the washing chamber 6, and the outer end of the washing chamber 6 is connected to the saponification chamber 7. A drying and discharge area 8 is provided on the outside of the saponification chamber 7. The drying and discharge area 8 can include a drying area and a discharge area. The drying area can be equipped with drying equipment as needed.

[0037] The center connecting lines of all pickling tank layouts and the center connecting lines of all phosphating tank layouts are not collinear. In this embodiment, the center connecting lines of the pickling tank layouts and the center connecting lines of all phosphating tank layouts are arranged perpendicularly.

[0038] A straight track I91 is set above the feeding area 3, the water-sealed feeding pool 2 and the pickling pool 1; a straight track II92 is set above the water washing process chamber 4; and a straight track III93 is set above the phosphating pool 5, the water washing chamber 6, the saponification chamber 7 and the drying and discharging area 8.

[0039] The straight tracks I 91, II 92 and III 93 are identical in specifications and height. The entire production line is equipped with one rail hoist 94, which enables the operation of the entire production line. In this embodiment, the rail hoist 94 is a turning rail hoist.

[0040] Example 2 discloses an acid pickling and phosphating production line. The difference between this example and Example 1 is that in this example, the center connecting line of the acid pickling tank layout and the center connecting line of all phosphating tank layouts form an acute angle; the water washing process chamber 4 includes an immersion tank 41 and a rinsing tank 42. The layout axis of the immersion tank 41 is collinear with the layout axis of the nearest acid pickling tank 1, and the layout axis of the rinsing tank 42 is collinear with the layout axis of the nearest phosphating tank 5.

[0041] like Figures 1 to 2 As shown, Embodiment 3 discloses an acid pickling and phosphating production line. The difference between this embodiment and Embodiment 2 is that the center connecting lines of all the acid pickling tanks 1 and all the phosphating tanks 5 are arranged parallel to each other and on the same side of the water washing process chamber 4. The center connecting lines of the immersion tanks 41 and rinsing tanks 42 are perpendicular to the center connecting lines of all the acid pickling tanks 1, so that the acid pickling process chamber and the phosphating process chamber are arranged in parallel. In this embodiment, an immersion tank is also provided between the acid pickling process chamber and the water washing process chamber 4 to avoid acid pickling solution residue as much as possible. The linear track II 92 is set above the axis of the immersion tanks 41 and rinsing tanks 42. The drying and discharge area 8 may include a drying area and a discharge area, wherein the drying area can be equipped with drying equipment as needed. In this embodiment, a guide rail 95 is provided between the feeding area 3 and the discharge area to facilitate the rework of some products with poor phosphating and enhance the on-demand flow capability of the entire production line.

[0042] Further optimization is possible, as the guide rail 95 has the same specifications and height as the linear track I 91 and is connected to it. In this embodiment, each of the linear track I 91, linear track II 92, linear track III 93, and guide rail 95 is equipped with at least one rail hoist 94. Each section of the track may have one hoist 94. When the production line is busy, multiple rail hoists 94 can be arranged along the entire track line. The number of rail hoists 94 on linear track I 91 is one less than the number of pickling tanks, and the number of rail hoists 94 on linear track III 93 is the same as the number of phosphating tanks 5.

[0043] It is understood that the above description is only for illustrating specific embodiments of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of disclosure of this application.
