Abstract
The invention relates to a method for dredging and treating coal slurry in various water sumps of coal mine, in particular to a method for dredging and treating coal slurry in a water sump of a coal mine. The method is not only applicable to the water sump of the coal mine, but also used for dredging and treatment of silt in various laneway water sumps. The method for dredging and treating the coal slurry in the water sump of the coal mine comprises the steps of diluting the coal slurry, stirring and slurry making, large-grain crushing, coal slurry conveying, cleaned coal extraction, coal slurry filter pressing (solid separation) and the like. The method can be used for automatically dredging and treating the coal slurry in various water sumps and extract the cleaned coal from the coal slurry so that the solid coal slurry is convenient to transport and store and the coal slurry is changed into valuable, and simultaneously the method improves the production efficiency.
Description
Technical field
What the present invention relates to the various water-house coal muds in a kind of colliery digs the method for handling with coal slime clearly, and particularly a kind of coal-mine water-house coal mud digs clearly and processing method, is not only applicable to coal-mine water-house, also can be used for digging clearly and sludge treatment of various laneway type sump mud.
Technical background
At coal industry, coal slime for coal-mine water-house and various laneway type sump, mud dig processing clearly, progressively emerge in large numbers some coal-mine water-house coal muds in recent years and dug method and apparatus clearly, some is applicable to that coarse slime digs clearly, only just solve coal slime entrucking problem (as publication: CN101338571 etc.), though some provides a whole set of technology and equipment (publication number: CN1676879A) to coal slime from digging processing clearly, but be confined to fine coal slurry, the coarse granule coal slime is not suitable for, therefore for digging and handle coal-mine water-house coal mud clearly and tunnel sump mud engineering is big, drop into lot of manpower and material resources, strengthened cost of production, and production efficiency is low, does not have good solution so far.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, provide dig a kind of comprising clearly, the dilution coal slime, stir pulping, the coal slime slurry is carried, extracting cleaned coal separates with coarse slime, the coal-mine water-house coal mud of steps such as coal slime Separation of Solid and Liquid digs clearly and processing method, can be used for various water-house coal muds (coal slime granular size no matter, the concentration height, the viscosity size, sump length) can automatically coal mud clearing totally and to coal slime be carried out cleaned coal extraction and Separation of Solid and Liquid processing, the solid coal slime is convenient to transportation and is stored, coal slime is turned waste into wealth, improved production efficiency simultaneously.
The present invention realizes with following technical scheme: a kind of coal-mine water-house coal mud digs clearly and processing method, it is characterized in that: the clear excavation method of coal slime is carried out as follows:
(1) encircles and hunts down the weir: play a cofferdam at the water-house coal mud rear portion;
(2) dilution coal slime: coal slime is broken up and dilute with water under high pressure;
(3) stir pulping: coal slime, the particularly big coal slime of coarse granule content with after step (2) dilution, adopt churned mechanically method fully to stir evenly, the bulky grain coal slime is suspended, form coal slurry;
(4) large granule coal slime fragmentation: the large granule coal slime that surpasses pumping and subsequent treatment requirement in the coal slime is carried out fragmentation, so that pumping is handled;
(5) the coal slime slurry is carried: adopt special-purpose coal slurrypump that the coal slime slurry is transported to Hatch Opening or designated treatment point, along with the extension of cleaning, spreading coal slime conveyance conduit;
The processing method of coal slime is carried out as follows:
(1) rough segmentation coal slime is extracted cleaned coal: the coal slime that is transported to Hatch Opening is separated earlier, therefrom extract the part cleaned coal, handle for next step coal slime press filtration and prepare;
(2) fine coal slurry continuous filter press, Separation of Solid and Liquid: the fine coal slurry that above-mentioned steps is separated is through the filter press filter-press dehydration, and coal slime is pressed into the solid pie, and separated flow returns the work sump;
(3) dry coal mud entrucking: the coal slime entrucking that will be pressed into solid.
Advantage of the present invention is: the characteristics that coal-mine water-house coal mud digs clearly with processing method are that compliance is strong, all handle for bulky grain, granule, thickness coal slime, need not manual intervention, sump is cleaned out thoroughly, coal slime is carried out cleaned coal extraction and Separation of Solid and Liquid processing, the solid coal slime is convenient to transportation and is stored, and coal slime is turned waste into wealth, and has improved production efficiency simultaneously.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Accompanying drawing is a process route chart of the present invention:
