Processing method for manufacturing green building material by recycling waste tailings

Abstract

The invention provides a processing method for manufacturing green building materials by recycling waste tailings. The processing method is completed by the cooperating of a U-shaped frame, two extrusion units, a main air cylinder, a bottom plate, two baffle units, a lifting air cylinder and an upper pressing unit. According to the processing method, the following problems can be solved, due to the fact that a mud section contains more bubbles and the bubbles are not treated by a traditional pressing blank, and thus more cavity structures are often formed in the fired building material brick;and when a mold is used for pressing the mud section, due to the fact that the mud section has viscosity, the adhesion degree between the mud section and the inner wall of the mold is increased through extrusion forming, thus the separation difficulty between a pre-pressing blank and the mold is increased, and forced separation often causes large-area falling of the surface of the pre-pressed blank.

Description

technical field [0001] The invention relates to the field of green building materials production, in particular to a processing method for making green building materials by reusing waste tailings. Background technique [0002] China is a country with rich mineral resources, and the amount of mine waste rocks and tailings produced is also huge. The damage to the environment caused by the mining industry and the depletion of earth resources have caused people to pay more and more attention to the treatment and recycling of mine solid waste. Now, personnel will Abandoned tailings are made into green new building materials, among which building material bricks made from tailings are a kind of green new building materials. [0003] When making building material bricks, it is usually necessary to extrude the processed mud section for high-temperature firing treatment. However, some problems are often encountered in the process of extruding the mud section: [0004] There are man...

AI Technical Summary

Problems solved by technology

[0004] There are many air bubbles in the mud section, and these air bubbles are not treated in the traditional preform, which often leads to more hollow structures inside the fired building material bricks. When using a mold to press the mud section, due to the stickiness of the mud section, Extrusion molding increases the degree of stickiness between the mud section and the inner wall of the mold, thus increasing the difficulty of separation between the preform and the mold, and forced separation often leads to a large area of ​​the surface of the preform falling off
