Container combined modular dense medium coal preparation system

Abstract

The invention aims to provides a container combined modular heavy medium coal separation system which is in a modular design, is convenient to disassemble or assemble or replace and move, and can be recycled. The system comprises a material feeding device, desliming devices, a main washing device, a product medium-removing device and a medium recovering device which are successively connected. The system further comprises a first module frame, a second module frame, a third module frame, a fourth module frame, a fifth module frame and a sixth module frame; the material feeding device is fixedly mounted on the first module frame to form a material feeding module so as to transport raw coal blocks to the desliming device, and the desliming devices are mounted on the second module frame and the third module frame, respectively, to form a desliming module which screens and transports raw coal to the main washing device; the main washing device is fixed on the fourth module frame to form a main washing module which separates middling coal and a gangue material and transports the same to the product medium-removing device; the product medium-removing device is fixedly mounted on the fifth module frame to form a medium-removing module so as to separate clean coal and media; and the medium recovering device is fixedly mounted on the sixth module frame which collects the media through the medium recovering device.

Description

technical field [0001] The invention relates to the technical field of mining machinery coal washing, in particular to a container combined modular dense medium coal preparation system. Background technique [0002] With the development of coal preparation mechanization, in the production of coal washing in modern mines, environmental protection requirements are becoming stricter, and the rate of coal washing is getting higher and higher. However, in some areas with low coal production, there is a shortage of energy, limited mine reserves, and limited site space. Therefore, large coal preparation plants in this area are faced with high investment, complex process configuration, large operation and maintenance, and economic benefits. Poor, difficult to move equipment and other related issues. [0003] The washing system of the coal mine preparation plant includes the main washing system, the slime water recovery system and the flotation and tailing coal recovery system, and ...

AI Technical Summary

Problems solved by technology

The main washing system is an important part of it. The main washing system includes process equipment such as feeding chute, desliming screen, medium desieving screen, coal slime bucket, medium bucket, dense medium cyclone, magnetic separator, pump, belt, etc. These equipment cannot be recycled and reused, and they cannot be moved. They are basically disposable system equipment, and the waste of plant equipment is serious.
