Classified mixing device for sand fine screening

Abstract

The invention discloses a classified mixing device for sand fine screening, and relates to the technical field of sand screening and mixing. The device comprises a box body, a shaking box is movably connected to the top of an inner cavity of the box body through a springback device, fixing plates are fixedly connected to the two sides of the shaking box correspondingly, and arc plates are fixedlyconnected to the bottoms of the fixing plates through supporting rods. According to the classified mixing device for sand fine screening, the right side wall of the box body is provided with an accessory feed inlet and an accessory discharge outlet in sequence from top to bottom, the top of the box body is provided with an opening matched with a feeding pipe, a bottom plate of the shaking box is provided with a leakage plate, the top of a rotating box is provided with a feeding through hole, and a through hole matched with a discharge pipe is formed in the position, corresponding to the discharge pipe, on the surface of a push plate, therefore, sand can be mixed according to different properties after being classified and screened, and the problem that sand screening devices on the marketcannot mix different kinds of sand in a classified mode is solved.

Description

technical field [0001] The invention relates to the technical field of sand screening and mixing, in particular to a sorting and mixing device for fine sand screening. Background technique [0002] Sand is one of the main components of concrete and mortar, and is a bulk material in civil engineering. Sand is generally divided into two types: natural sand and artificial sand. Rock particles formed by natural conditions (mainly rock weathering) with a particle size of less than 5 mm are called natural sand. Artificial sand is made by crushing rocks. Because of its high cost and many flakes and powders, it is generally not used. According to its different sources, natural sand can be divided into river sand, sea sand and mountain sand. The surface of mountain sand is rough, the particles are angular, the sand content is high, the content of organic impurities is also high, and the quality is poor. The surface of sea sand and river sand is smooth, and single sea sand has a lot...
