A kind of intermittent semi-automatic flotation sorting system

Abstract

The invention belongs to the technical field of resource sorting, and provides an intermittent semi-automatic flotation separation system. The intermittent semi-automatic flotation separation system comprises a sorting container. Separation micro powder is contained in the sorting container. A hanging basket is further arranged in the sorting container. Small holes are formed in the surface of thehanging basket. A plurality of air nozzles are densely distributed at the bottom of the sorting container. The density of the separation micro powder is between the densities of two types of to-be-separated materials. The diameter of the small holes in the surface of the hanging basket is larger than the particle size of the separation micro powder and smaller than the particle sizes of the two types of to-be-separated materials. According to the semi-automatic flotation separation system, the air nozzles work to blow the separation micro powder and the two types of to-be-separated materialsupwards together and to mix the separation micro powder and the two types of to-be-separated materials, and the two types of to-be-separated materials and the separation micro powder are naturally separated to three layers under the effect of the gravity; after primary layering, the small-density to-be-separated materials on the upper layer are taken out; then to-be-separated materials continue tobe poured into the sorting container, the air nozzles blow air to achieve pneumatic layering; after materials are layered and taken out multiple times, the whole hanging basket is taken out; in the process of taking the hanging basket out, the separation micro powder flows out of the small holes densely distributed in the hanging basket, to-be-separated materials with large densities are mostly left in the hanging basket, and thus, to-be-separated materials with large densities are separated from to-be-separated materials with small densities; and the sorting method is simple, and the sortingeffect is good.

Description

technical field [0001] The invention belongs to the technical field of resource sorting, in particular to an intermittent semi-automatic flotation sorting system. Background technique [0002] In the field of resource recovery, metal sorting technology is often used, and metal sorting is to separate different metal scraps. The current metal sorting technology includes jigging flotation sorting, eddy current sorting, jet sorting and so on. Chinese patent "CN201280007107.8" discloses a scrap metal sorting system that can sort scrap metals that contain at least two metal categories. This is done by directing an x-ray beam at at least a portion of the scrap metal pellet. Backscattered x-rays, forwardscattered x-rays, and transmitted x-rays from the particle are measured and input into a classifier, such as a database with cutoff planes. The scrap metal is sorted by a controller into a first category and a second category of scrap metal. An x-ray source for a scanning system ...
