Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel plate pickling, in particular to a steel plate pickling equipment with sewage recycling structure. BACKGROUND

[0002] After the steel plate is pickled, water washing is needed to wash away the acid liquid and impurities on the surface of the steel plate. A small amount of acid remains in the water after water washing. After the acid is neutralized, the water can be reused. Directly discharging the water after water washing into the environment will cause waste of water resources.

[0003] The existing steel plate pickling equipment has the following defects:

[0004] 1. The existing technology KR20180021627A discloses a steel plate cleaning equipment. This technology does not have a structure for recycling the acid liquid after cleaning the steel plate and recycling the water, which can easily cause water waste. Therefore, a steel plate pickling equipment with sewage recycling structure that can recycle the acid liquid and water after pickling the steel plate is needed to solve this problem.

[0005] 2. The existing technology US20090283110A1 discloses a method for cleaning hot galvanized steel plate and its cleaning equipment. This technology does not have a structure for pre-filtering the recycled water. If there are impurities in the water when the recycled water enters the recycling tank, the impurities will easily adhere to the inner wall of the recycling tank, making it difficult to clean the recycling tank. In addition, if there are too many impurities in the water, subsequent treatment of the water will also be difficult. Therefore, a steel plate pickling equipment that can pre-filter the water entering the recycling tank and facilitate cleaning and replacement of the filtering structure is needed to solve this problem.

[0006] 3. The existing technology JP2005060791A discloses a steel plate cleaning equipment. When the steel plate is immersed in water, the impurities in the steel plate enter the water. When the water is discharged, the impurities in the water will easily adhere to the inner wall of the steel plate cleaning container. When the water enters the cleaning container again, the impurities will easily enter the water, causing the water to not clean the steel plate properly. Therefore, a steel plate pickling equipment with sewage recycling structure that can remove the impurities on the inner wall of the container for cleaning the steel plate is needed to solve this problem.

[0007] 4. The existing technology CN116555778B discloses an acid pickling equipment based on steel plate surface cleaning. This technology does not have a structure for detecting the pressure of the scraping plate on the steel plate when scraping the acid liquid on the surface of the steel plate of different thicknesses. When the pressure of the scraping plate on the steel plate is too large, the steel plate will be easily scratched, and the movement of the steel plate will be inconvenient. Therefore, a steel plate pickling equipment with sewage recycling structure that can scrape the acid liquid on the surface of the steel plate while avoiding excessive pressure of the scraping plate on the steel plate is needed to solve this problem.
