Description

Filtering and screening device for fine sand aggregate

Technical Field

The utility model relates to a construction machinery equipment technical field specifically is a filtration sieving mechanism of fine sand aggregate.

Background

Aggregate is also known as "aggregate". The concrete and mortar are granular materials with the functions of framework and filling. The sand comprises fine aggregate and coarse aggregate, the particle diameter of the fine aggregate is 0.16-5 mm, natural sand such as river sand, sea sand, valley sand and the like is generally adopted, and when the natural sand is lacked, artificial sand ground by hard rocks can be used; the particle diameter of the coarse aggregate is more than 5mm, the common crushed stone and pebbles are used, the strength of the crushed stone concrete is higher than that of the pebble concrete under the same condition, but the crushed stone is formed by crushing rocks and has higher cost than that of the pebbles, the common coarse aggregate in the light aggregate concrete comprises natural porous rocks such as pumice and the like, artificial porous aggregates such as ceramsite, expanded slag and the like, and the aggregate is used as a main raw material in the concrete and plays a role in framework and support in buildings. When the aggregate is mixed, the cement is stirred by water to be thin paste, if no aggregate is added, the cement cannot be molded, and cannot be used, so that the aggregate is a very important raw material in construction, and the aggregate with the particle size of more than 4.75mm is called coarse aggregate, commonly called stone. Two types of gravel and pebbles are commonly used. The crushed stone is made of natural rock or rock through mechanical crushing and sieving, and has a particle size larger than 4.75 mm. Pebbles are rock particles with a particle size of more than 4.75mm, which are formed by natural weathering, water flow transportation, sorting and stacking. The needle-shaped particles are the cobble and broken stone particles with the length 2.4 times larger than the average particle diameter of the corresponding grade of the particles; the particles having a thickness of less than 0.4 times the average particle diameter are flaky particles (the average particle diameter means the average of the upper and lower limit particle diameters of the fraction). The construction pebbles and gravels meet the technical requirements of the national standard GB/T14685 plus 2001 construction pebbles and gravels; in the building engineering, before the aggregate is used, screening equipment is required to screen the aggregate, so that impurities and the aggregate which does not meet the specification are removed; the existing equipment can not fully filter out impurity dust in aggregate, is easy to block meshes of a screen, and is usually inconvenient to use due to large volume.
