A kind of preparation process of concrete

Abstract

The invention discloses a concrete preparation process, which includes the following steps: step 1, controlling the downward movement of the first stone material screening assembly to open the feeding port, and preparing the cementitious materials, water, admixtures and admixtures required for the preparation of concrete Add it into the shell; step 2, put the crushed stones into the first stone screening assembly, control the first stone screening assembly to perform preliminary screening of the crushed stones, and when it is detected that the weight of the stones in the first stone screening assembly remains unchanged, control The first stone screening assembly moves upward to close the feeding port, and at the same time, the large crushed stones in the first stone screening assembly fall into the second stone screening assembly; Step 3, control the stirring assembly to stir the materials in the shell; Step 4, After the concrete is mixed and formed, the discharge port of the shell is opened, and the concrete is sent out from the discharge port; the concrete preparation process is not only simple to operate, but also can quickly complete the preparation of concrete.

Description

technical field [0001] The invention belongs to the technical field of concrete, in particular to a concrete preparation process. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is an artificial stone made of cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary. It is uniformly stirred, densely formed, cured and hardened. Concrete has, It has the characteristics of high compressive strength, good durability and wide range of strength grades. At present, the existing concrete production and manufacturing usually have the following deficiencies: 1. The existing equipment cannot effectively screen the crushed stone materials when preparing and processing the concrete, resulting in easy inclusions in the finished materials after mixing Large crushed stones affect the subsequent processing and use of finished materials; 2. In the existing technology center, the screening ...

AI Technical Summary

Problems solved by technology

At present, the existing concrete production and manufacturing usually have the following deficiencies: 1. The existing equipment cannot effectively screen the crushed stone materials when preparing and processing the concrete, resulting in easy inclusions in the finished materials after mixing Large crushed stones affect the subsequent processing and use of finished materials; 2. In the existing technology center, the screening machine can only screen crushed stones of one size. If the screening size needs to be changed, it is time-consuming to replace the screen mesh 3. Concrete preparation equipment that can be screened usually has the problem of gravel clogging the screen holes, resulting in low filtration efficiency and affecting the concrete production schedule
