Fine sand cleaning and recycling mechanism of mudstone regenerating system

Abstract

The invention discloses a fine sand cleaning and recycling mechanism of a mudstone regenerating system. The fine sand cleaning and recycling mechanism comprises a fine sand feeding device, a fine sand cleaning device and a fine sand sorting device; the fine sand feeding device comprises at least one feeding conveyor belt; the fine sand cleaning device comprises rotary cleaning balls; water spray pipes are arranged inside the cleaning balls; a plurality of small holes are formed in the outer walls of the cleaning balls; the fine sand sorting device comprises vibrating screens, diameters of which are gradually reduced; the vibrating screens are sequentially arranged from top to bottom; each screen can be inclined towards one end; and during inclining, the low end of each screen is connected to a corresponding material receiving hole through an elastic device. According to the fine sand cleaning and recycling mechanism disclosed by the invention, the cleaning balls with small holes in outer walls are arranged, so that mudstones are rotated by the cleaning balls and water spraying pipes inside the cleaning balls are used for spraying water, and therefore, mud flies out from the small holes under action of centrifugal force. Openings in the lower parts of the cleaning balls are opened, so that fine sand without the mud is sequentially screened through screens from openings in the lower parts of the cleaning balls. The mud is firstly removed, and fine sand is sorted, so that the probability that blockage is caused by the mud is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of crushing, cleaning and recycling equipment for mud-rock mixture, and in particular relates to a fine-sand cleaning and recycling mechanism of mud-rock regeneration system. Background technique [0002] In the prior art crushed stone sand production, whether it is a dry process or a wet process, there are certain restrictions on the soil content of the raw materials. Especially in the dry process, the raw materials need to be standard materials, and the restrictions on soil content are more stringent, and in the dry process, only 75% to 80% of the rubble can be made into finished products, and 20% to 25% of the rubble. Will be discarded as stone chips. All in all, the dry process is not only expensive but also easy to raise a large amount of dust, which causes great pollution to the environment. Therefore, the wet process is generally used in the crushed stone sand making industry. The wet process of cru...

Problems solved by technology

[0006] In the above-mentioned prior art, while classifying the fine sand, the fine sand containing soil in the cylindrical screen is sprayed with water, and the soil is easy to cause the blockage of the screen, especially the screen with a small diameter.
