Description

Cooling device for recycled concrete production

Technical Field

The utility model relates to a cooling device specifically is a cooling device is used in recycled concrete production.

Background

The regenerated concrete is prepared by crushing, cleaning and grading waste concrete blocks, mixing the crushed, cleaned and graded waste concrete blocks with a grading agent according to a certain proportion, partially or completely replacing natural aggregates (mainly coarse aggregates) such as sand stones and the like, and adding cement, water and the like. Aggregates prepared from waste concrete are called recycled concrete aggregates (referred to as recycled aggregates for short). The recycled aggregate prepared only by simple crushing and screening processes has more edges and corners, rough surface, and also contains hardened cement mortar in components, and in addition, a large amount of microcracks are caused in the interior due to damage accumulation in the crushing process of concrete blocks, so that the recycled aggregate has high porosity, high water absorption, small stacking density, high porosity and high crushing index. When the recycled aggregate is used in a reinforced concrete structure, the recycled aggregate needs to be reinforced. Wherein the heating and grinding method is one of the ideal processes for preparing high-quality recycled aggregate.

However, the heating and grinding method is to subject the primarily crushed concrete blocks to heating treatment at 300-400 ℃ to dehydrate and embrittle the set cement, and to carry out impact and grinding treatment on the set cement under the condition of ensuring that the aggregate is not crushed, so as to effectively take out the set cement residue in the recycled aggregate. The aggregates need to be cooled after grinding treatment, and the current cooling methods are divided into natural cooling and water spray cooling. The natural cooling speed is too slow, so that the production efficiency is low, but the strength of the aggregate is not influenced; the water spray cooling speed is fast, and is efficient, but the cooling mode that cooling water directly sprays on high temperature aggregate is too violent, can lead to the intensity and the performance of regeneration aggregate to receive the influence to still can waste water resource. Therefore, the utility model provides a cooling device is used in recycled concrete production to solve the problem that proposes in the above-mentioned background art.
