Abstract

The invention relates to a recycled concrete aggregate screening system, and relates to the field of concrete aggregate screening. The recycled concrete aggregate screening system comprises a screening device and a collecting device, the screening device comprises a rack, a rotary drum and a filtering sleeve, a feeding channel is formed in the rotary drum, first filtering holes are formed in the outer side wall of the rotary drum, the filtering sleeve and the rotary drum are spliced to form a first filtering cavity, and second filtering holes are formed in the filtering sleeve; a feeding opening is formed in the rack, and a driving piece is arranged on the rack. The driving piece is controlled to drive the rotary drum to rotate, then recycled concrete aggregate is fed, the recycled concrete aggregate enters the feeding channel, fine aggregate falls into the first filtering cavity, coarse aggregate is left in the rotary drum and rolls to the collecting device, the aggregate with the small diameter in the fine aggregate falls to the collecting device through the second filtering holes, and the aggregate with the large diameter is left in the first filtering cavity and then falls to the collecting device, so that multi-stage screening of the recycled concrete aggregate is achieved, the screening precision is higher, aggregate screening is more convenient, and the screening efficiency of the aggregate can be improved.

Description

technical field [0001] The present application relates to the field of concrete aggregate screening, in particular to a recycled concrete aggregate screening system. Background technique [0002] With the continuous acceleration of the country's urbanization process, the demand for building materials in the development of urbanization continues to rise, resulting in a rapid increase in the amount of construction waste in the city. While enjoying urban civilization, people are also suffering from urban waste. trouble. [0003] Recycled concrete means that waste concrete blocks are crushed, cleaned and graded, mixed with gradation in a certain proportion, partially or completely replaced by natural aggregates (mainly coarse aggregates) such as sand and gravel, and then added with cement, water, etc. new concrete. [0004] The coarse and fine aggregates in recycled concrete aggregates are unevenly distributed, and aggregates with too large diameters are not suitable for opera...
