Preparation process and preparation device for recycled concrete aggregate

Abstract

The invention relates to the technical field of aggregate preparation, in particular to a preparation device for the recycled concrete aggregate. A conveying plate is fixedly connected to the upper end of a conveying support frame; a feeding plate is fixedly connected to the right side of the conveying plate; a preparation box is fixedly connected to the upper surface of a support frame; a feedinghole is formed in the upper surface of the preparation box; a discharging hole is formed in the side surface of the preparation box; a fixed shaft is fixedly connected to the inner wall of the preparation box; a first sliding seat is connected to the interior of the fixed shaft in a sliding manner and comprises a rotating shaft, a rotating seat and a pushing seat; the rotating shaft is rotatablyconnected to the outer surface of the first sliding seat; the rotating seat is rotatably connected to the outer surface of the rotating shaft; and the pushing seat is fixedly arranged on the upper surface of the first sliding seat. When the preparation device for the recycled concrete aggregate is used, too many raw materials are prevented from being adhered to the preparation box, and the preparation box is cleaned by itself without the staff, is convenient to clean, avoids the wasting of the raw materials, and enables the raw materials to be fully used.

Description

technical field [0001] The invention relates to the technical field of aggregate preparation, in particular to a preparation process of recycled concrete aggregate and a preparation device thereof. Background technique [0002] In recent years, with the acceleration of industrialization and urbanization, and the rapid development of the construction industry, people have over-exploited natural aggregate resources, resulting in a decrease in natural aggregates, which has continuously increased people's attention to the protection of related natural resources To this extent, it is an effective way to solve the problem of resource shortage by using waste garbage and other raw materials brought by the construction industry to produce recycled aggregates for the preparation of new concrete. A certain amount of old mortar adheres to the surface of recycled concrete coarse aggregates. Since the apparent density of mortar is lower than that of natural aggregate, the apparent density...

Problems solved by technology

[0003] In the aggregate production process, it needs to be screened in order to obtain high-quality aggregates. Currently, the screening process is generally troublesome, and the screening effect is poor. Sometimes the screening process may cause The screening tank is clogged, which affects the use of the screening plate. At the same time, under long-term screening, the inner wall of the screening box is often bonded with some aggregates, which is difficult to clean and wastes a certain amount of waste to a certain extent. Aggregate, in order to solve the above problems, a preparation process of recycled concrete aggregate and its preparation device are now provided
