Abstract
The invention discloses an automatic pretreatment device for recycled aggregates, which includes a feeding system, a coating system, a discharging system and a control system. The feeding system, the coating system and the discharging system are all connected to the control system. The side of the coating system is equipped with a feeding system, and the lower part is provided with a discharge system; the coating system includes a mixing tank, the two sides and the bottom of the mixing tank are connected with telescopic arms, and the mixing tank is equipped with a feeding system. The top of the slurry feeding chamber is provided with a piston plate, and the bottom is provided with a number of slurry outlet holes. A rotating shaft runs through between the slurry feeding chamber and the mixing barrel, and the rotating shaft is connected to the power device above the slurry feeding chamber. The invention can pre-wet the recycled aggregates in different degrees, reduce the negative impact of high water absorption and large porosity of the recycled aggregates; realize automatic processing of recycled coarse aggregates; can prepare high-strength recycled aggregates, improve Utilization value of recycled aggregate.
Description
technical field [0001] The invention relates to a pretreatment device, in particular to an automatic pretreatment device for recycled aggregate. Background technique [0002] With the acceleration of urbanization in our country, the demand for stone as an indispensable resource for making concrete is increasing day by day. At the same time, with the advancement of urban shanty town renovation projects, the demolition of old buildings will generate a large amount of construction waste. If not handled properly, it will not only generate high land acquisition fees, but also cause environmental pollution. Therefore, it has become a hot topic nowadays to recycle construction waste and obtain recycled aggregate through crushing and screening methods to re-prepare concrete blocks and apply them to projects. [0003] The high porosity and high water absorption of recycled aggregates will affect the performance of recycled concrete, so pretreatment of recycled aggregates is required...
