Description

Technical Field

[0001] The utility model belongs to the technical field of recycled concrete mixing, and in particular relates to a mixing and stirring device for recycled concrete construction. Background Art

[0002] Recycled concrete, also known as recycled concrete, is an environmentally friendly building material made by crushing, screening, washing and other processes of discarded concrete blocks, using them as part or all of the aggregate to replace natural aggregates, and mixing them with cement, water and admixtures when necessary to make new concrete. This practice aims to reduce the impact of construction waste on the environment while saving natural resources.

[0003] The mixing process of recycled concrete is one of the key steps in its preparation, which involves mixing raw materials such as recycled aggregate, cement, water, fly ash, admixtures, etc. in specific proportions to obtain a concrete mixture that meets engineering requirements.

[0004] During the recycled concrete mixing process, the recycled concrete mixing tank and mixing mechanism need to be cleaned after mixing. If they are not effectively cleaned, they will solidify inside the mixing tank after a long time and will be difficult to clean. In addition, when the next group of recycled concrete with a different ratio is mixed, the residual concrete of the previous group will contaminate the mixing of the next group of concrete.
