A device and preparation method for producing mortar using steel slag sand

Abstract

A device and method for producing mortar using steel slag sand are provided, the device includes a steel slag sand grinder, a sealed box and a mixing bucket, and the sealed box includes: a temperature and humidity controller and a pressure controller, which are fixedly connected to the sealed One side of the box is respectively used to control the temperature and pressure in the sealed box; the screening box is fixedly connected to the bottom of the sealed box, and the screening box includes a row fixedly connected to one side of the screening box A chip pipe, wherein, a dust removal system is fixedly installed at one end of the chip discharge pipe close to the screening box; A carbon dioxide storage tank, the carbon dioxide storage tank is in fixed communication with the sealed box through a connecting pipe. The invention enables the sealed box to quickly screen the steel slag sand after the steel slag sand is stabilized, discharges and collects waste chips and impurities in the steel slag sand, greatly saves the time for steel slag sand screening, and improves production. efficiency.

Description

technical field [0001] The invention relates to the technical field of steel waste recycling building construction, in particular to a device and a preparation method for producing mortar by using steel slag sand. Background technique [0002] The standards for cement-based radiation-proof materials in my country currently include GB / T50557-2010 "Technical Specifications for the Application of Barite Radiation-proof Concrete" and GB / T34008-2017 "Radiation-proof Concrete", among which the GB / T50557-2010 standard uses barite For the production of anti-radiation concrete, the GB / T34008-2017 standard is to use iron ore to produce anti-radiation concrete. There are no relevant standards and specifications for anti-radiation mortar in my country, and the standard specification for the production of anti-radiation mortar using steel slag sand is even blank. [0003] The existing anti-radiation mortar produced by using steel slag sand is difficult to grind and has poor stability, res...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a device and preparation method for producing mortar using steel slag sand. In view of the deficiencies of the prior art, this design scheme has the advantages of effectively solving the poor stability of steel slag sand and being able to produce radiation-proof mortar. It solves the problem that steel slag sand is difficult to grind and has poor stability, which leads to the ineffective utilization of large quantities of waste residue left after production in the building materials industry
