Raw material screening treatment equipment used for concrete building production and processing

Abstract

The invention discloses a raw material screening treatment equipment used for concrete building production and processing. The raw material screening treatment equipment used for concrete building production and processing comprises a box body, wherein a first-stage screening mechanism is arranged at the upper end of a side wall of the box body, a feeding assembly is arranged at the upper end of the left side wall of the box body, the feeding assembly is movably connected with the first-stage screening mechanism, and second-stage screening mechanisms are arranged at both the upper end and the lower end of the inner wall of the box body. When gravel materials need to be subjected to screening treatment, the materials are put into the first-stage screening mechanism through the feeding assembly, large gravel materials are screened out through the first-stage screening mechanism, relatively-large materials, relatively-small materials and small materials fall into the box body, the relatively-large materials can be screened through the second-stage screening mechanism arranged at the upper end of the inner wall of the box body, the relatively-small materials can be screened through the second-stage screening mechanism arranged at the lower end of the inner wall of the box body, and the small materials naturally fall off, and are discharged out of the box body, so that the multi-stage screening effect is achieved, and the situation that the efficiency of screening the gravel raw materials is affected by multiple times of screening is avoided.

Description

technical field [0001] The invention relates to the field of concrete production, and more specifically relates to a raw material screening and processing equipment for production and processing of concrete buildings. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is composed of cementitious materials, granular aggregates, also known as aggregates, water, and admixtures and admixtures added when necessary. It is a kind of artificial stone material that is mixed, densely formed, cured and hardened. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has high compressive strength and good durability. , Wide range of strength grades and other characteristics, these characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development,...

AI Technical Summary

Problems solved by technology

[0003] In the process of concrete processing, it is necessary to select different specifications of sand and gravel according to different needs. The mixed use of different specifications of sand and gravel can improve the quality of concrete. Therefore, it is necessary to screen the sand and gravel before use. The sand and gravel are of different sizes, so the sand and gravel will be screened multiple times to meet the use requirements, and multiple screenings will seriously affect the screening efficiency of raw materials, thereby reducing the production efficiency of concrete
