Description

Technical Field

[0001] The utility model relates to the technical field of metal workpiece processing, and more particularly to a degreasing device for metal surface treatment and processing. Background Technique

[0002] When deforming or cutting metal, some oil stains often adhere to the surface of metal products. The process, technique, method, etc. of removing oil stains from the metal surface is called degreasing or oil removal, and the common degreasing methods include: surfactant degreasing, organic degreasing, pickling degreasing, electrolytic degreasing, etc.

[0003] After retrieval, the existing patent (publication number: CN214813002U) discloses an environment-friendly degreasing device for metal surface treatment and processing. During its use, when a metal part is placed on a conveyor belt for transportation, the degreasing agent in the liquid storage tank can flow down through the through pipe in the sleeve. When the degreasing agent flows to the bottom end of the through pipe, it will evenly enter the sponge through the liquid distribution pipe. When the metal part passes through the sponge, the degreasing agent inside the sponge can enter the metal part through the elasticity of the sponge, enabling the metal part to maximally contact the degreasing agent and improving the degreasing effect of the device. Finally, the water flow sprayed by the high-pressure nozzle is used to wash the irregular parts inside the metal to ensure the effect of removing oil stains from the metal. However, the inventor found the following problems in the process of implementing the present utility model: For the above-mentioned degreasing device, when placing the metal product on the surface of the conveyor belt for transportation, it can only apply the degreasing agent and perform cleaning operations on the upper surface and side surface of the metal, while for the lower surface of the metal in contact with the conveyor belt, there is a serious lack of the effect of degreasing treatment, resulting in a large defect in the degreasing treatment process and being difficult to meet the use requirements.
