Usually, the staff drives the tanker to a special concrete separation tank for cleaning. The concrete contained in the washing liquid after cleaning can be recycled. Generally, the solid and liquid are separated step by step in the separation tank, and the sediment (recyclable sand and cement) is collected. However, when collecting the solid, the staff shovels the cement to one side of the separation tank and then shovels it out of the separation tank. The work efficiency is low. For the cement at the bottom of the separation tank or the cement stuck to the inner wall of the separation tank, the staff needs to enter the separation tank to shovel and collect the cement. The operation is inconvenient and labor-intensive.

Moreover, the above scheme still requires manual cleaning of sand and gravel impurities, which wastes manpower, is time-consuming and labor-intensive. Therefore, we need a sedimentation tank for concrete cleaning water to increase work efficiency. Utility Model Content
