Technical Field

[0001] The invention belongs to the technical field of construction waste solid waste recycling and treatment, and in particular relates to a construction waste recycled aggregate manufacturing device and method. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals. At present, some aggregates in construction waste can be recycled and then used again, so they are called aggregates.

[0003] A complete construction waste treatment production line includes processes such as crushing, sorting and cleaning. There is a large amount of slag after the construction waste is crushed. After crushing, the slag enters the coarse screen with the aggregate, and most of the slag is screened out from the aggregate, but some of the slag is not screened out due to vibration and other effects. These slags enter the classification process with the aggregates. The slag adheres to the surface of the aggregates, affecting the accuracy of classification, such as screening aluminum and copper in the aggregates through color sorting.

[0004] Therefore, the existing construction waste recycled aggregate manufacturing device has the disadvantage of inaccurate aggregate classification due to the adhesion of slag to the aggregate. Summary of the invention

[0048] The plate feeder 1 is used to receive construction waste and evenly feed the construction waste into the primary crusher 2; the primary crusher 2 crushes the construction waste, and a jaw crusher, an impact crusher, a cone crusher, etc. can be used; the vibrating screening machine 3 screens the construction waste according to the size of the crushed construction waste, and divides it into slag, primary recycled aggregate and secondary recycled aggregate; the aggregate cleaning and classification mechanism 4 can screen out light materials, iron materials and part of slag in the recycled aggregate, and divide the recycled aggregate into medium materials and heavy materials, the medium materials include foam bricks and red bricks with lower density, and the heavy materials include stones, etc.

[0049] Compared with the prior art, the construction waste recycled aggregate manufacturing device provided in this embodiment can accurately screen the slag, light materials, medium materials, heavy materials and iron materials in the recycled aggregate through the arrangement of a plate feeder, a primary crusher, a vibrating screening machine and an aggregate cleaning and sorting mechanism. Moreover, since the heavy materials and medium materials are cleaned, the color sorting and screening of materials such as copper and aluminum can also improve the accuracy of color sorting and improve the quality of the recycled aggregate.

A method for producing recycled aggregate from construction waste, characterized in that: The preparation of recycled aggregate using the construction waste recycled aggregate manufacturing device as described in claim 6 comprises the following steps: Step 1: Construction waste is fed into the plate feeder (1); Step 2: transporting the construction waste to the primary crusher (2); Step 3: The primary crusher (2) crushes the construction waste; Step 4: The crushed construction waste is separated into slag, primary recycled aggregate and secondary recycled aggregate by a vibrating screening machine (3) and discharged; Step 5: Removal of light materials from recycled aggregates; Step 6: Removal of iron from recycled aggregates: Step 7: Using an air separation component (406) to separate the recycled aggregate into medium materials and heavy materials according to density by air separation; Step 8: Collect light materials; In step 8, the wind blown out by the wind separation component (406) is collected by the water-recycling component (405) through wind collection, and the water surface of the cleaning flotation component (401) is moved to make the light matter float to the light matter lifting and collecting component (402), thereby realizing the collection of the light matter; when the light matter is transferred from the water surface of the cleaning flotation component (401) to the light matter receiving frame by the light matter lifting and collecting component (402), the spray head flushes the debris on the surface of the light matter, and the debris enters the cleaning flotation component (401) along the water guide groove and the water guide frame with the water.
