A method for pretreatment of raw materials for the preparation of thermal insulation concrete

Abstract

The invention relates to a raw material pretreatment method for preparing thermal insulation concrete, which mainly includes the following steps: equipment inspection, raw material input, raw material screening, leftover material recovery, cleaning and maintenance, and the used concrete raw material screening device includes a mounting frame, a collection chamber, The sieving kit and the recovery kit, the installation frame is equipped with a collection chamber, the upper end of the collection chamber is provided with a sieve kit, the lower end of the sieve kit is provided with a recovery kit, and the recovery kit is located outside the collection chamber. The following problems exist in pre-preparation c: a: The existing concrete raw materials are often mixed with large particles of stone impurities during the mixing process before the preparation, which will affect the quality of the concrete in the subsequent preparation of concrete; b: The existing concrete is screened The sieved large particles are often directly placed outside, and are extremely easy to be mixed into concrete raw materials in subsequent processing, which requires secondary screening of concrete, which wastes costs and affects production capacity.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a method for pretreatment of raw materials for the preparation of thermal insulation concrete. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to the use of cement as cementitious material, sand, stone as aggregate and water in a certain proportion. The cement concrete obtained by mixing, also known as ordinary concrete, is widely used in civil engineering. Now the preparation of concrete requires multiple processes such as equipment inspection, raw material feeding, raw material screening, leftover material recycling, cleaning and maintenance of concrete raw materials. . [0003] The existing concrete raw materials often have the following problems before preparation: a: The existing concrete raw materials are o...

Problems solved by technology

[0003] The existing concrete raw materials often have the following problems before preparation: a: The existing concrete raw materials are often mixed with impurities such as larger particles of stones when mixing the materials before preparation, which will affect the quality of the concrete in the subsequent preparation of concrete. The quality of the concrete is reduced according to the phenomenon; b: The large particles sieved out of the existing concrete after sieving are often directly placed outside, and it is extremely easy to be mixed into the concrete raw materials in the subsequent processing, so that the concrete needs to be secondary Second screening, extremely wasteful cost, and affect production capacity
