Description

Technical Field

[0001] This utility model relates to the field of pickling and phosphating tank technology, and in particular to a pickling and phosphating tank. Background Technology

[0002] Pickling and phosphating is a metal surface pretreatment process that mainly includes two key stages: First, an acidic medium is used to chemically react with the iron oxide and rust layer on the steel surface to achieve the cleaning and activation of the base metal; then, on the deoxidized and activated metal surface, the metal substrate is immersed in phosphating solution and temperature is controlled to promote a displacement reaction between the metal substrate and the solution, generating a micron-sized phosphate crystal film.

[0003] Chinese patent CN213357751U discloses a steel pickling and phosphating tank, including a tank body and a heating coil located at the bottom of the tank body. The key technical feature is the inclusion of a stirrer within the tank body. The stirrer shaft extends into the tank from the outside of the bottom, and a mechanical seal is used at the connection between the stirrer shaft and the tank body. A trough is located within the tank body, above the stirrer. This pickling and phosphating tank enables convection of the phosphating solution within the tank under stirring, ensuring uniform heating and a homogeneous composition of the phosphating solution at each location, thus promoting the formation of a uniform and high-quality phosphating film on the steel surface.

[0004] However, the above technical solution has the following shortcomings: Although the trough in the pickling and phosphating tank allows each side of the steel to come into contact with the phosphating solution through the set steel reinforcement frame, the steel reinforcement frame is placed directly by inserting it through the through hole during use. When the trough is raised or lowered, it is easy to cause the steel reinforcement frame to shift, which may result in the steel reinforcement frame detaching from the through hole. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an acid pickling and phosphating tank that ensures the stability of the support structure when placing workpieces separately, while also being easy to operate and convenient to use.

[0006] The present invention provides a pickling and phosphating tank, comprising a tank body and a partitioning mechanism. The tank body contains an immersion frame with multiple drainage holes. The partitioning mechanism includes two vertically distributed frames that are engaged within the immersion frame, a steel reinforcement frame on the frame, multiple symmetrically distributed fixing blocks with grooves on the immersion frame, a limiting plate on the frame, a bottom plate on the immersion frame, two insert rods penetrating the limiting plate and inserted into the bottom plate, and two symmetrically distributed guide support blocks on the frame. Two corners of the frame abut against the interior of the grooves. The immersion frame has a sliding groove for the guide support blocks to slide horizontally, and the limiting plate and the immersion frame are in close contact.

[0007] Preferably, the interior of the tank is equipped with heat exchange tubes.

[0008] Preferably, the tank is equipped with a stirring mechanism, which includes two horizontally rotating rods inside the tank, multiple stirring blades arranged in a linear array along the axial direction of the rods, a support on the tank, and a motor on the support; the motor and the support are connected in a drive connection.

[0009] Preferably, the tank has two horizontally distributed crossbars inside, and the soaking frame is located on the crossbars.

[0010] Preferably, the soaking frame is provided with two symmetrically distributed mounting plates, and the mounting plates are provided with driving components.

[0011] Preferably, the drive assembly includes a vertically telescopic hydraulic rod and a connecting assembly for connecting the hydraulic rod and the mounting plate. The connecting assembly includes a connecting disc disposed on the hydraulic rod and six fixing bolts arranged in a ring array and passing through the connecting disc. The mounting plate is provided with threaded grooves for threaded connection of the fixing bolts.

[0012] Preferably, the soaking frame is provided with two symmetrically distributed guide sliders, and the inside of the tank is provided with two guide grooves for the guide sliders to slide vertically.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This invention, through the combination of a partitioning mechanism and a stirring mechanism, ensures that the steel can fully contact the phosphating solution at a suitable temperature during immersion, while also guaranteeing the stability of the rebar frame and preventing the frame from shifting or detaching during lifting and lowering. Furthermore, the operation of fixing the rebar frame is simple and convenient, demonstrating its excellent practicality. Attached Figure Description

[0020] Example 1

[0021] like Figures 1-4 As shown, the pickling and phosphating tank proposed in this embodiment includes a tank body 1 and a partitioning mechanism; an immersion frame 2 is provided inside the tank body 1, and multiple leakage holes 5 are provided on the immersion frame 2.

[0022] The separating mechanism includes two frames 3 that are distributed vertically and interlocked inside the soaking frame 2, a steel frame 4 on the frame 3, multiple fixing blocks 6 symmetrically distributed on the soaking frame 2 and having grooves, a limiting plate 7 on the frame 3, a base plate 9 on the soaking frame 2, two insert rods 8 that penetrate the limiting plate 7 and are inserted into the base plate 9, and two guide support blocks 10 symmetrically distributed on the frame 3; the two corners of the frame 3 abut against the inside of the groove, the soaking frame 2 is provided with a sliding groove for the guide support blocks 10 to slide horizontally, and the limiting plate 7 and the soaking frame 2 are in close contact with each other.

[0023] In this embodiment, when the workpiece needs to be soaked, a certain number of workpieces are first placed at the bottom of the soaking frame 2. Then, the frame 3 and the steel bar frame 4 are inserted into the soaking frame 2 through the limiting plate 7. The frame 3 is guided and supported by the guide support block 10 and the sliding groove. The frame 3 slides until the corner of the frame 3 abuts against the groove of the fixing block 6 and then stops pushing. Then, a certain number of workpieces are placed on the steel bar frame 4. The subsequent operation is the same to place the workpieces until the frame is full. The size and number of layers of each layer can be controlled according to the needs. When the frame is full, the two insert rods 8 are passed through the holes on the limiting plate 7 from top to bottom until the bottom of the insert rods 8 is inserted into the bottom plate 9, thus completing the placement of the workpieces. This not only ensures that the steel can fully contact the phosphating solution during soaking, but also fully guarantees the stability of the steel bar frame 4, avoiding the frame 3 from shifting or detaching when the soaking frame 2 is raised and lowered. The operation is simple and convenient and has good practicality.

[0024] Example 2

[0025] like Figure 1 and Figure 4As shown in the figure, the pickling and phosphating tank proposed in this embodiment, compared with the first embodiment, has a heat exchange tube 11 installed inside the tank body 1. The opening of the tank body 1 is equipped with an end cap (not shown) with a temperature detector to keep the liquid warm and measure the temperature. The tank body 1 is equipped with a stirring mechanism, which includes two horizontally rotating rods 12 installed inside the tank body 1, multiple stirring blades 13 linearly arrayed along the axial direction of the rotating rods 12, a support 14 installed on the tank body 1, and a motor 15 installed on the support 14. The motor 15 and the support 14 are drivenly connected. The rotating rods 12 extend from the bottom of the tank body 1 into the tank. The rotating rods 12 and the bottom of the tank body 1 are mechanically sealed.

[0026] In this embodiment, heat exchange tube 11 is used to exchange heat with phosphating solution to heat the liquid. Temperature detector is used to control the liquid temperature to quickly and effectively remove oxides and rust from the metal surface and form a high-quality phosphating film. During immersion, motor 15 is started, which drives rotating rod 12 to rotate. Rotating rod 12 drives multiple sets of stirring blades 13 to rotate, which accelerates the flow of liquid inside tank 1 and ensures that the liquid flows fully in the tank, thus ensuring the uniformity of the treatment effect.

[0027] Example 3

[0028] like Figure 1 , Figure 2 and Figure 4 As shown in the figure, the pickling and phosphating tank proposed in this embodiment has two horizontally distributed crossbars 16 inside the tank body 1 compared with the first embodiment. The soaking frame 2 is located on the crossbars 16. When the soaking frame 2 is inside the tank body 1, it is placed on the crossbars 16 to support the soaking frame 2. At the same time, the height of the crossbars 16 is higher than that of the stirring blades 13 to avoid the collision between the stirring blades 13 and the soaking frame 2.

[0029] The soaking frame 2 is provided with two symmetrically distributed mounting plates 17. The mounting plates 17 are provided with a drive assembly. The drive assembly includes a vertically telescopic hydraulic rod 18 and a connecting assembly for connecting the hydraulic rod 18 and the mounting plate 17. The connecting assembly includes a connecting plate 19 provided on the hydraulic rod 18 and six fixing bolts 20 arranged in a ring array and passing through the connecting plate 19. The mounting plate 17 is provided with a threaded groove for threaded connection of the fixing bolts 20.

[0030] The soaking frame 2 is provided with two symmetrically distributed guide sliders 21, and the inside of the tank 1 is provided with two guide grooves for the guide sliders 21 to slide vertically.

[0031] In this embodiment, after the workpiece is processed, the hydraulic cylinder drives the hydraulic rod 18 to rise. The hydraulic rod 18 drives the mounting plate 17 and the soaking frame 2 to rise through the connecting plate 19. The guide slider 21 plays a stabilizing role when the soaking frame 2 is raised and lowered. After standing for a period of time, some of the liquid that was carried up falls back into the tank 1. Then the processed workpiece can be taken out from top to bottom. The fixing bolts 20 and the connecting plate 19 make it easy to install and disassemble the soaking frame 2, improving the convenience of using the equipment.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
