Description

Technical Field

[0001] The utility model relates to the technical field of building material waste recycling, in particular to an impurity removal device for preparing concrete aggregates from building material waste. Background Art

[0002] Concrete refers to a mixture of organic, inorganic or organic-inorganic composite, granular aggregate, water, and chemical admixtures and mineral admixtures in appropriate proportions, or a composite material with a stacking structure formed after hardening. It is usually made of cementitious materials, water, fine aggregate, coarse aggregate, admixtures and mineral admixtures when necessary, in appropriate proportions. Recycled aggregate is mainly used to replace natural aggregate to prepare ordinary concrete or ordinary mortar, or as a raw material for the production of non-fired blocks or non-fired bricks, with different concrete or mortar.

[0003] The existing Chinese patent with announcement number CN219817009U discloses a device for removing impurities from recycled building aggregates, and the key points of its technical solution are: the impurity removal screen plate and the material guide plate are arranged in sequence from top to bottom inside the box body of the impurity removal box, and a magnetic adsorption mechanism is arranged between the impurity removal screen plate and the material guide plate inside the box body of the impurity removal box. When the utility model performs impurity removal and screening work on the recycled building aggregate, the conductive magnetic plate in the magnetic adsorption mechanism is used to contact the material guide of the recycled building aggregate after vibration screening. While the recycled building aggregate is being guided and unloaded, it can also maintain a comprehensive magnetic attraction release work with the iron filings impurities in the recycled building aggregate, and perform comprehensive magnetic attraction and impurity removal on the iron filings impurities in the recycled building aggregate. When the conductive magnetic plate magnetically attracts more iron filings impurities on one side, the conductive magnetic plate can be turned over to perform continuous and efficient magnetic attraction and impurity removal work on the iron filings impurities.

[0004] The above-mentioned prior art solution has the following defects: although the above-mentioned technical solution can continuously and efficiently magnetically remove iron filings and impurities by turning over the magnetically conductive plate, the above-mentioned technical solution cannot crush the construction waste during the screening and impurity removal. After the impurities are removed, it is necessary to use another crushing equipment to crush it before it can be recycled, which greatly reduces its practicality. Utility Model Content
