Description

Technical Field

[0001] This utility model relates to the field of ADI casting technology, and in particular to an ADI casting pickling treatment device. Background Technology

[0002] ADI (Austenitizing Dioxide) is a ductile iron material formed through austenitization and isothermal quenching. Its matrix consists of bainite, retained austenite, and acicular ferrite, exhibiting high strength, wear resistance, and shock absorption properties. Its specific gravity is approximately 10% lower than steel, resulting in significant cost-effectiveness, and it is widely used to replace steel and aluminum components. However, when oil or other impurities accumulate on the surface of ADI castings, pickling is typically required for removal. Traditional processes necessitate manual handling of the castings for immersion and retrieval, followed by rinsing, which is time-consuming and labor-intensive. Furthermore, when the oil contamination on the surface of ADI castings is thick, direct pickling can easily lead to localized treatment failure, necessitating extended pickling time or increased acid concentration. This indirectly increases acid consumption and subsequent rinsing load, implicitly raising production costs. Therefore, this paper proposes a pickling device for ADI castings to address these issues. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide an ADI casting pickling device, addressing the aforementioned technical deficiencies. This device automates the pickling of castings, pre-treating thick oil stains on the casting surface, reducing costs and facilitating operation.

[0004] The technical solution adopted by this utility model is as follows: An ADI casting pickling treatment device is provided, including a suspended conveyor. The device is characterized by: multiple connecting frames installed on the suspended conveyor; a mesh shell installed at the other end of each connecting frame; a soaking tank, a drying channel, a pickling tank, and a rinsing channel sequentially arranged on one side of the suspended conveyor; a casting pickling and placement area on the other side of the suspended conveyor; a descent area corresponding to the soaking tank and the pickling tank on the suspended conveyor; and filter plates installed in both the drying channel and the rinsing channel.

[0005] To further optimize this technical solution, both the immersion tank and the pickling tank of an ADI casting pickling treatment device are trapezoidal.

[0006] To further optimize this technical solution, a drying channel of an ADI casting pickling treatment device includes two drying plates corresponding to the mesh shell; a water filter plate is located at the drying plate.

[0007] To further optimize this technical solution, a rinsing channel of an ADI casting pickling treatment device includes two rows of water spray heads, the orientation of which corresponds to the mesh shell; a filter plate is located between the two rows of water spray heads.

[0008] Compared with traditional pickling equipment, the advantages of this invention are as follows:

[0009] 1. The setup of the mesh shell, suspended conveyor, connecting frame, pickling tank, water spray head, and filter screen facilitates automatic pickling, making it more convenient to use and to pick and place castings that need to be pickled.

[0010] 2. When the oil stains on the surface of ADI castings are thick, the castings are first soaked in the bath and then dried. Some solvent will also flow out through the filter plate. Then the mesh shell drives the castings to pickle and rinse, which is convenient for pickling ADI castings with thick oil stains. The degree of automation is high and it is more convenient to use.

[0011] 3. Both the soaking tank and the pickling tank are trapezoidal, so when the casting is moved, most of the adhering liquid will flow into the tank through the inclined surface. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-4 As shown, an ADI casting pickling treatment device includes a suspended conveyor 1, characterized in that: multiple connecting frames 2 are installed on the suspended conveyor 1; a mesh shell 3 is installed at the other end of the connecting frame 2; a corresponding soaking tank 4, drying channel, pickling tank 5, and rinsing channel are sequentially arranged on one side of the suspended conveyor 1; a casting pickling and placing area 6 is located on the other side of the suspended conveyor 1; a descending area 7 corresponding to the soaking tank 4 and the pickling tank 5 is provided on the suspended conveyor 1; filter plates 8 are provided at both the drying channel and the rinsing channel; both the soaking tank 4 and the pickling tank 5 are trapezoidal; the drying channel includes two drying plates 9 corresponding to the mesh shell 3; the filter plates 8 are located at the drying plates 9; the rinsing channel includes two rows of water spray heads 10, the orientation of which corresponds to the mesh shell 3; the filter plates 8 are located between the two rows of water spray heads 10.

[0019] The castings requiring pickling are placed on the mesh shell 3 and moved by the overhead conveyor 1. The overhead conveyor 1 moves the mesh shell 3 via the connecting frame 2. The mesh shell 3 first passes through the soaking tank 4, then through the drying channel, and finally reaches the pickling tank 5. The pickling tank 5 soaks and pickles the castings. After pickling, the mesh shell 3 and the castings reach the rinsing channel, where water spray heads 10 rinse the castings. The rinsing wastewater is collected through a filter screen, and the pickled castings then reach the casting pick-and-place area 6 on the other side of the overhead conveyor 1. Figure 4 As shown, it facilitates automatic pickling, making it more convenient to use and easier to pick and place castings that need pickling;

[0020] When the oil stains on the surface of ADI castings are thick, direct pickling can lead to localized "failures," requiring extended pickling time or increased acid concentration, indirectly increasing acid consumption and subsequent rinsing burden, thus implicitly increasing costs. For such castings, organic solvents can be added to the immersion tank 4. The castings will first pass through the organic solvents in the immersion tank 4 for rapid degreasing. After degreasing, the castings will reach the drying channel, where the drying plate 9 will be turned on to dry the castings, drying off the solvent adhering to the castings. Some of the solvent will also flow out through the filter plate 8, preventing water accumulation. Then, the mesh shell 3 will carry the castings for pickling and rinsing, facilitating the pickling treatment of ADI castings with thick oil stains. This method has a high degree of automation and is more convenient to use.

[0021] Both the soaking tank 4 and the pickling tank 5 are trapezoidal, so when the casting is moved, most of the adhering liquid will flow into the tank through the inclined surface.

[0022] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
