Embodiment Construction

[0018] In the following, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0019] A flexible air chamber jig system with particle swirling and layering, as attached figure 1 and figure 2 shown. In this device, the water inlet 2 and the water inlet valve 3 are installed on the jig machine body 1 first; the air bag 16 is fixed at the corresponding position by the bolt 5 and the connecting flange 4, and then the support seat 15 and the support seat 15 are installed on the inner wall of the body 1. The spring 14 is compressed, and the sieve plate 6 is fixed on the spring 14 . In order to ensure the stable pulsation of the sieve plate 6, the limiter 7 is installed on the inner wall of the machine body 1 above the sieve plate. The inclined bucket 10 is installed on the body 1, and pipeline accessories are installed at the tangential position of the outer wall, which are the horizontal incidence pipeline 8 and the ...

Abstract

The invention relates to a flexible air chamber jigging machine system of particle rotational flow layering and a layering method. By additionally arranging a fixed support base and springs, a traditional fixed sieve plate structure is changed, so that a sieve plate moves under the effect of pulse water flows, then, liquid-phase and solid-phase flows on a drive plate generate pulses, the particlepulse amplitude is improved, density layering is reinforced, and the sorting efficiency can be improved; in a liquid-solid mixture layering area above the sieve plate, by adding the effect of tangentially incident water flows, rotational flows are generated in the liquid-solid mixture layering area, and the layering efficiency is improved; traditional straight borders are changed into a inclined hopper, so that flow resistance in the up-and-down pulse process of a liquid-solid mixture is reduced, energy loss is reduced, and the system running efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of liquid-solid two-phase separation of particles. In particular, it relates to a flexible air chamber jigging machine system and a layering method with particle swirl layering, which are used in the fields of separation engineering and mineral processing engineering, especially related to underground coal gangue discharge, coal separation, and ultra-pure coal preparation. technical field. Background technique [0002] Mineral resources are a gift from nature to human beings, which can guarantee the material basis needed. The development of science and technology and industry has higher and higher requirements on the quality of mineral raw materials. The direct mining of raw ore often fails to meet the standard. It is necessary to process the raw ore through mineral processing, and gradually formed a discipline of mineral processing engineering with rich connotations. Jigging is a mineral processing method...
