TCS intelligent coarse slime sorting machine

Abstract

The invention provides a TCS intelligent coarse slime sorting machine. The TCS intelligent coarse slime sorting machine depends on upward flow and an intelligent interference device to function together. The intelligent coarse slime sorting machine with dynamic interference comprises a sorting cylinder, a center feeding cylinder, an upward flow stabilizing system, a backwater nozzle, a concentrate overflow box, a tailing discharging mechanism, the intelligent interference device, a densitometer and an intelligent control system. According to the TCS intelligent coarse slime sorting machine, the intelligent control system controls the intelligent tailing discharging mechanism composed of a tailing discharging pump and a constant-pressure water tank and the like to discharge high-ash coal gangue continuously and stably. The automatic adjustment of sorting density between 1.40-1.80 kg / L can be achieved, the tailing ash content can reach more than 60%-75%, the tailing ash can be directly discharged with gangue or comprehensively utilized, and the concentrate product recovery rate and the economic benefit of enterprises are improved.

Description

technical field [0001] The invention belongs to the technical field of separation of coal, water treatment, and other useful minerals and gangues with density differences, and in particular relates to an intelligent separation equipment for coarse coal slime (other minerals or water treatment). Background technique [0002] The 2015 government work report pointed out: "To strengthen the clean and efficient utilization of coal". The clean and efficient utilization of coal requires a technology system that starts with coal washing and is guided by efficient and clean coal combustion. According to data from the China Coal Processing and Utilization Association, for every 100 million tons of raw coal selected, about 18 million tons of coal gangue can be excluded. It can eliminate about 13 million tons of ash, nearly 350,000 tons of sulfur, and reduce sulfur dioxide emissions by 490,000 tons. At the same time, using washed and processed clean coal as fuel can increase coal combu...

AI Technical Summary

Problems solved by technology

[0006] (1) Spiral separator: The spiral separator belongs to the principle of flow film separation, and the concentrated coarse coal slime is fed into the spiral from the top of the spiral separator. In the groove, the spiral descends. In the spiral groove, the coarse-grained coal slime is mainly affected by gravity, centrifugal force, water flow driving force, and friction force, so that the low-density material is in the upper layer of the water flow and moves to the thickest water layer on the outer edge of the spiral; while The high-density material is in the lower layer of the water flow, and moves to the thickest part of the water layer at the inner edge of the spiral to finally achieve separation; the advantage of the spiral separator is its simple structure, and its sorting size is generally 1.5-0.15mm. It is used in the Shendong area of ​​China. , Jincheng, Datong, and Shuozhou in Shanxi have a large number of applications. The disadvantages are: the separation density is generally required to be greater than 1.7kg / L, which is suitable for the desulfurization process; it is not suitable for coking coal preparation plants with a separation density of less than 1.7kg / L. ; The tailings ash content is generally 40~60%

Its sorting particle size is generally 1.0~0.25mm. It has a large number of applications in coking coal preparation plants such as Shanghai Temple in Inner Mongolia, Lu'an in Shanxi, Hejin in Shanxi, and Xingtai in Hebei. The disadvantage is that the sorting density used is generally less than 1.7kg / L, mostly used in coking coal preparation plants; the ash content of tailings is generally 40~60%, and the loss of clean coal is serious
