Description

Quick sieving mechanism of city construction sand

Technical Field

The utility model relates to a sieving mechanism specifically is a quick sieving mechanism of urban construction sand.

Background

Sands are generally classified into natural sands and artificial sands. Rock particles having a particle size of 5mm or less, which are formed by the action of natural conditions (mainly weathering of rocks), are called natural sand. Artificial sand is made by crushing rock, and is generally not used due to high cost and many flaky and powdery substances. Natural sand can be classified into river sand, sea sand and mountain sand according to its source. The sand has rough surface, multi-edge angle, high sand content, high organic impurity content and poor quality. The sea sand and river sand have smooth surfaces, but the sea sand has high salt content, has certain influence on concrete and mortar, and is relatively clean and widely applied. The thickness of the sand is an average thickness of sand grains of different sizes mixed together. Generally, the sand is divided into coarse sand, medium sand and fine sand. The grain composition of the sand refers to the matching proportion of sand size grains. As can be seen from the figure, if the sands with the same thickness are used, the gap is the largest, the sands with two grain sizes are matched, the gap is reduced, and the sands with three grain sizes are matched, the gap is smaller. Therefore, the porosity of the sand depends on the matching degree of the grain sizes of all the sand. The graded sand not only can save cement, but also improves the compactness and strength of concrete and mortar. The thickness of the sand is represented by the fineness modulus Mx. The larger the fineness modulus, the coarser the sand. According to the size range of the fineness modulus, the sand is divided into coarse sand, medium sand, fine sand and extra-fine sand.

In order to get rid of the impurity in the sand, need get rid of inside granule impurity such as dust with the sand washing usually, sand adhesion need be earlier sand drying together in order to prevent when screening, later get rid of the large granule impurity in the sand, and current device needs the manual work of going to connect and get the sand after getting rid of the large granule impurity in the sand, and work efficiency is low, has increaseed staff's work burden. Therefore, the utility model provides a quick sieving mechanism of city construction sand to solve the above-mentioned problem of proposing.
