Coal treatment system

Abstract

The invention relates to a coal treatment system. The system comprises a coal preparation system, a tailing water treatment system for treating tailing water generated by the coal preparation system,and a recovery coal bunker for recovering coal slime generated by the tailing water system, wherein the tailing water treatment system comprises a thickener, a water exchange device and a filter press; two output ends at the bottom of the thickener are respectively connected with the input end of the water exchange device and the input end of the filter press; and an output end connected with therecovery coal bunker and a first underflow pump connected with the input branch end of the thickener are arranged at the bottom of the filter press. The coal treatment system fully utilizes underground water, enables a circulating water system of the tailing slime water system to be changed into small circulation from large circulation, simplifies process, reduces production accident points, lowers energy consumption, and reduces equipment maintenance investment and personnel labor cost.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and more specifically relates to a coal processing system with improved structure. Background technique [0002] Coal treatment mainly includes coal preparation and tailings slime water treatment. During coal preparation, a large amount of water resources are required to configure production chemicals, but due to the influence of coal pits, groundwater cannot be fully utilized, and the use of tap water for dispensing increases production costs; For the general tailing coal water treatment system, including sedimentation tanks, sedimentation tank pump rooms, gantry cranes and other production links, there are many links in the circulating water system of water treatment, which greatly increases the investment cost of equipment maintenance and labor, and the frequency of accidents is also greatly increased. Increase; the complex circulation system makes it impossible to replenish water in time ...

During coal preparation, a large amount of water resources are required to configure production chemicals, but due to the influence of coal pits, groundwater cannot be fully utilized, and the use of tap water for dispensing increases production costs; For the general tailing coal water treatment system, including sedimentation tanks, sedimentation tank pump rooms, gantry cranes and other production links, there are many links in the circulating water system of water treatment, which greatly increases the investment cost of equipment maintenance and labor, and the frequency of accidents is also greatly increased. Increase; the complex circulation system makes it impossible to replenish water in time during production. Similarly, the amount of circulating water separated from the tailing coal slime water after being treated by the thickener is large, and sufficient water storage space is required
