Description
Technical Field
The invention relates to the technical field of coarse coal slime recovery, in particular to an automatic system and method for coarse coal slime recovery energy conservation.
Background
The coal slime is a byproduct with the granularity of less than 0.5mm in a coal preparation plant, and the coarse coal slime is particles with the granularity close to that of the coal slime, generally more than 0.3-0.5 mm, and is not suitable for flotation treatment. The primary coal slurry is formed by coal dust contained in selected raw coal. The secondary coal slime refers to the coal slime generated by crushing and argillization of coal in the coal dressing process.
Currently, the current practice is. In the coal slime flotation process, coarse coal slime recovery is an important component of a coal preparation plant, and the tasks of the coarse coal slime recovery are as follows: dehydrating the sorted product; recovering clean coal with qualified quality, so that the clean coal does not enter coal slime water; and removing the fine-grained materials which are not sorted, and enabling the fine-grained materials to enter subsequent operation for reprocessing. The commonly used coarse slime recovery processes include the following steps:
the method comprises a first step of a dewatering screen-bucket pit-dragging coarse coal slime recovery process, wherein the screen hole of the dewatering screen is usually 13mm, and the coarse coal slime recovered from the pit is subjected to twice dehydration through a desliming screen and a centrifugal dehydrator to form a subsequent product. And (4) a system for recovering fine coal slime from overflow of the bailing pit. The process has the characteristics that: the management is convenient, the use is reliable, the experience is rich, and the application is wide; the upper limit of the feeding material for flotation can be well ensured, but the circulation amount exists locally. The application range is as follows: the method is suitable for the condition that the separation lower limit of main separation equipment is low, and if the separation lower limit is high, the quality of clean coal is polluted;
and secondly, a double-layer dewatering screen-pyramid pool coarse slime recovery process, wherein the aperture of the upper layer of the double-layer screen is 13mm or 25mm, and the aperture of the lower layer of the double-layer screen is 3mm, 1mm or 0.5 mm. The pyramid pool is used as coarse slime recovery equipment. The process has the characteristics that: the material amount entering the pyramid is less, and the grading is facilitated; the high-ash fine mud has less pollution to clean coal, and mainly because the water entering the lower-layer sieve is large, the fine mud on the surface of the material on the sieve is easy to wash away, so that the desliming efficiency is improved; the upper limit of flotation feeding can be well ensured, but the part still has circulation quantity. The application range is as follows: the process is suitable for the conditions of high content of fine mud and high ash content.
And thirdly, the aperture of the double-layer dewatering screen in the bucket pit dragging-double-layer dewatering screen coarse slime recovery process is the same as that in the previous step. The process has the characteristics that: the light products of the main selection equipment all enter the fishing pit, the flow is simple, and the number of equipment is small; the feed amount of the fishing pit is large, the grading precision is low, clean coal is polluted to a certain extent, and when the lower limit of the sorting of main sorting equipment is high, the pollution is more serious; the dredging hole is used for dredging the materials into the double-layer dewatering screen, so that the double-layer screen has low desliming efficiency and pollutes clean coal.
And fourthly, a coarse coal slime recovery flow of the dewatering screen and the electromagnetic vibration cyclone screen is similar to the coarse coal slime recovery flow of the dewatering screen and the bucket digging pit, and the bucket digging pit is only replaced by the electromagnetic vibration cyclone screen. The process has the characteristics that: the cyclone sieve has small occupied area, large treatment capacity and accurate classification; the cyclone sieve also has dewatering and ash-reducing functions while classifying. The application range is as follows: it is suitable for medium and small sized coal preparation plant with small treatment capacity.
And fifthly, a centrifugal screening device-high frequency screening coarse coal slime recovery process, wherein the coal slime centrifugal screening device is used as hydraulic classification equipment in the process, and the high frequency screening device is used as dehydration equipment in the process. The process has the characteristics that: the flow is simple, and the equipment is few; the volume is small, the treatment capacity is large, and the grading is accurate; the pollution of high-ash fine mud to clean coal can be reduced; can effectively prevent coarse particle materials from entering the next procedure. The application range is as follows: it is suitable for medium and small sized coal preparation plant with small treatment capacity.
And sixthly, a coarse coal slime recovery flow of the dewatering screen, the dredging pit and the swirler is similar to the coarse coal slime recovery flow of the dewatering screen and the bucket dredging pit, and the coarse coal slime recovery swirler is added. The process has the characteristics that: the quantity of circulating coal slime in the system is very small, and fine mud can be prevented from accumulating; can effectively prevent coarse particle materials from entering the next procedure. The application range is as follows: the method can be used for coal preparation plants with wider screen gaps of centrifuges and stricter requirements on upper limit of flotation feeding. The specific coarse coal slime recovery process depends on the conditions of coal slime property, clean coal quality requirement, clean coal quantity and the like. The concrete problems should be specifically analyzed in the actual work of the coal preparation plant.
All need the electric energy monitoring to the machinery that every flow was used, the tradition does not all carry out the power consumption monitoring to the motor of each device, when electric leakage or power consumption were revealed, not only can cause personnel's life safety to receive the threat to still a large amount of extravagant electric energy, all just need an economizer system that can monitor.
