Abstract
Description
Technical Field
[0001] This utility model relates to the field of modification treatment technology, and in particular to a surface modification treatment device for recycled aggregates. Background Technology
[0002] Recycled aggregate refers to granular materials obtained by processing waste building materials such as concrete and bricks through a series of processes including crushing, screening, and washing, which can be used to replace natural aggregates. The surface of recycled aggregate usually has impurities such as old cement mortar adhering to it, resulting in problems such as high porosity, high water absorption, low strength, and irregular particle shape. Therefore, to improve the performance of recycled aggregate, it is often necessary to use processing equipment to modify the surface of the recycled aggregate.
[0003] However, when existing processing equipment is used for heat treatment, the location of the aggregate and the heating structure can easily lead to uneven heat transfer and different temperatures inside and outside the aggregate. This results in a large difference in the degree of surface modification treatment between the inner and outer surfaces of the aggregate, which cannot fully improve the overall performance of the aggregate. Utility Model Content
[0004] Therefore, the purpose of this utility model is to propose a surface modification treatment device for recycled aggregates to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0005] To achieve the above objectives, one embodiment of this utility model provides a surface modification treatment device for recycled aggregate, including a conveyor frame for conveying recycled aggregate. One end of the conveyor frame is provided with a heat treatment chamber for heating the recycled aggregate. Inside the heat treatment chamber is an arc-shaped fan-blade heating wheel for heating the recycled aggregate. Inside the arc-shaped fan-blade heating wheel are cross-distributed cutting blades. One end of each cutting blade is fixedly installed with a locking buckle for fixing and adjusting it. Inside the cutting blade is a detection seat for support and fixation. Inside the detection seat is a temperature sensor for wireless signal communication. The temperature sensor is wirelessly connected to a main control unit. The main control unit is signal-connected to a temperature display screen for displaying data.
