Description

Technical Field

[0001] The utility model relates to the technical field of pickling and passivation, in particular to a pickling and passivation cleaning pool. Background Art

[0002] Pickling passivation is mainly used to remove all kinds of oil, rust, scale, welding spots and other dirt on the surface of stainless steel, making the treated surface uniform silver-white and greatly improving the corrosion resistance of stainless steel. This treatment is suitable for various types of stainless steel parts, plates and equipment.

[0003] After searching, Chinese patent announcement number CN220579402U discloses a stainless steel pickling passivation tank, which relates to the field of pickling passivation, including a base, the upper end of the base is fixedly connected to the purification tank body, the upper end of the base is fixedly connected to the cleaning component, the upper end of the base is fixedly connected to the moving component, the upper ends of the moving components are fixedly connected to support rods, the opposite sides of the support rods are provided with slide grooves, the upper ends of the support rods are fixedly connected to the adjustment components, and the opposite sides of the adjustment components are fixedly connected to the mounting plates. The utility model adopts the above structure, so that the purification effect can be achieved in all directions under the rotation of the stainless steel parts, further increasing the practicality of the device, and at the same time avoiding the stainless steel parts in the pickling passivation tank from stacking each other and being in a static state, which easily leads to the inability of some workpieces to fully contact with the pickling passivation liquid, so that there are residual dirt such as oil, rust, oxide scale and welding spot on the surface of the stainless steel parts.

[0004] However, in the above technical solution, the purification frame is only driven to rotate by a belt, so that the metal parts in the purification frame rotate with the purification frame, thereby avoiding incomplete pickling and passivation due to the delicacy of the metal parts. However, the metal parts collide with each other while rotating with the purification frame, generating noise. The collision of metal parts with each other in the pickling and passivation tank can easily cause liquid splashing and pollute the surrounding environment of the cleaning tank, and bring risks to the safety of surrounding personnel.
