Description

Technical Field

[0001] This utility model relates to the field of waste hydrochloric acid oil removal technology, specifically, to a waste hydrochloric acid oil removal device. Background Technology

[0002] In the steel and metal products industries, hydrochloric acid is used for pickling to remove iron oxide scale from the surface of steel during the production process. In the manufacturing process of hot-rolled steel plates, if the hot-rolled steel plates are not pickled, their surface is similar to that of many ordinary steel plates on the market. The rusted surface is red. In order to remove the oil stains from the hot-rolled steel plates, acidic degreasing agents are generally used. Although the degreasing ability is generally average, it can remove both oil stains and rust.

[0003] In existing technologies, waste hydrochloric acid is usually sprayed onto the surface of hot-rolled steel plates produced by manual labor at a specific processing location using a spraying device, in order to clean the oil stains on the hot-rolled steel plates.

[0004] The existing degreasing methods described above have the following shortcomings:

[0005] When the hot-rolled steel plate is sprayed manually through a spraying device, after one side is sprayed to remove oil, it needs to be flipped over to spray the other side to remove oil. Since the hot-rolled steel plate is heavy and not easy to flip, this reduces work efficiency and increases labor costs.

[0006] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content
