Modification treatment device and modification treatment method for recycled aggregate

Abstract

The invention discloses a modification treatment device and a modification treatment method for recycled aggregate. The modification treatment device comprises a modification unit, which comprises a chain transmission device, a water tank, a limiting frame and two supporting columns, wherein the limiting frame comprises two vertical rods, the tops of the two vertical rods are connected with a horizontal rod, the motors of gears at the two ends of the chain transmission device are fixed to the tops of the two supporting columns, the supporting column is higher than the horizontal rod, the middle of a chain is located at the bottom of the horizontal rod, a plurality of hoisting containers are arranged below the chain of the chain transmission device at intervals, and are connected with the chain through mooring ropes, openings are formed in the tops of the hoisting containers, meshes are formed in the bottoms of the hoisting containers, the water tank is located below the middle of the chain and contains a modified material solution, and the distance between the hoisting container and the chain is equal to the distance between the middle of the chain and the water tank. With the device and the method, the efficiency of modification treatment adopting the mortar stabilizing and strengthening principle can be improved, and an assembly line operation mode is formed.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a modification treatment device and method for recycled aggregate. Background technique [0002] In the existing recycled aggregate modification technology, removing the mortar and taking the original natural aggregate is one of the mainstream directions. However, the stripping process is difficult, and the process of stripping will also cause the risk of the natural recycled aggregate in the mortar being broken again. Obviously, it is not feasible to strip the natural fine aggregate, that is, sand from the recycled aggregate; at the same time, it will cause The large particle size material after simple crushing cannot be used, and it is only suitable for recycled concrete. [0003] Another mainstream is stabilizing and strengthening mortar, which can maintain the particle size after simple crushing, make full use of recycled aggregates, and modify recycled aggregates in advance,...

AI Technical Summary

Problems solved by technology

On the premise of not destroying the graded recycled aggregate, permeable materials can modify recycled clay bricks and recycled concrete at the same time. It is certain that in the future modified recycled aggregates, permeable materials must Occupy a place, but at present, the modified treatment of the principle of stabilizing and strengthening mortar is used, which is inefficient and cannot form an assembly line operation mode
