Abstract

The invention discloses an under-shaft drilling water treatment device which can be used for purifying slime water produced in under-shaft working, solid-liquid separation of slime water is realized, the clean water is recycled and reused in a drilling machine, and the slime is dehydrated and transported out. By utilizing the device, the on-site treatment and recycling of drilling slime water is realized, the water conveying quantity to the shaft from the ground is greatly reduced, the problem that environment pollution is caused by the slime water produced by the under-shaft drilling machine is thoroughly solved, and the full-automatic operation of the system is realized, so that the working intensity of works is greatly reduced.

Description

A kind of down-hole drilling water treatment device

Technical field

The present invention's design relates to a kind of down-hole drilling water treatment device.

Background technology

Down-hole rig water consumption is very large, and separate unit rig water consumption is 10 ~ 20m generally speaking ³/ h, and strict to water quality requirement, otherwise can damage rig, therefore the rig water is provided to the down-hole by ground fully, consumed a large amount of pure water, these water namely become black water after using through rig, and its amount is very large, common way is to discharge on the spot or directly enter sump, the discharging meeting causes serious pollution to working environment at coal mines on the spot, and causes the waste of coal resources, enters sump and then can cause slime content increase in the sump, alluvial is serious, needs often cleaning.If these boring black waters can be realized solid-liquid separation after suitably processing, the clear water direct reuse is in rig, not only solved problem of environmental pollution, and improved coal recovery rate, also can bring significant economic benefit for enterprise, what is more important ground can significantly be reduced to the down-hole pushing quantity, and the frequency of sump desilting can reduce greatly.And at present, domestic complete drill hole of drilling machine circulating water treatment device do not appear also.

Summary of the invention

A kind of down-hole drilling water treatment device, described a kind of down-hole drilling water treatment device comprises black water collecting tank, black water preprocessor, chemicals dosing plant, coagulation thickner, water quality on-line detector, accurate filter, coal slime pressure filter, mine car, pump, spill box, filtered water tank, valve; It is characterized in that, after the black water that rig produces enters the black water collecting tank, by being pumped in the black water preprocessor, remove diameter greater than the particle of 0.5mm, pack into the mine car transportation of this part particle, enter the coagulation thickner through pretreated black water, black water after concentrated enters the coal slime pressure filter, pack into the mine car transportation of slime filter cake after the press filtration, produce filtrate water after the press filtration and return the coagulation thickner, the overflow clear water that the coagulation thickner produces enters accurate filter and carries out purifying treatment, water after the purification enters filtered water tank, for rig, water quality line detector is installed in coagulation thickner water outlet and accurate filter water outlet, and dosing mouth is on the pipeline between black water preprocessor and the coagulation thickner.

Down-hole drilling water treatment device of the present invention can be realized drill hole of drilling machine black water cycling and reutilization, water quality after the processing satisfies the requirement of rig water, can be to the equipment injury, system device can be realized steady and continuous product water during processing rig recirculated water, greatly reduced the pushing quantity of ground to the down-hole, and reclaimed as much as possible coal slime, reduce coal slime warehouse entry amount, reduced the frequency of sump desilting, system realizes fully automatic operation, greatly alleviates workman's labour intensity.

Embodiment

The drill hole of drilling machine black water comes pipe material 1 to enter black water collecting tank 2 by the boring black water, enter black water preprocessor 3 by black water collecting pump 12, the macrobead interception is removed, the macrobead of interception enters mine car 11, black water through preprocessor 3 enters coagulation thickner 5, black water through coagulation thickner 5 concentration enters coal slime pressure filter 13, slime filter cake after the press filtration enters mine car 11, the overflow supernatant water of coagulation thickner 5 enters water quality on-line detector 6, detection through water quality testing meter 6, if water quality reaching standard, then start valve 14-1, and valve-off 14, supernatant water enters spill box 10, if water quality is not up to standard, valve-off 14-1 then, start valve 14, supernatant water returns coagulation thickner 5, clear water in the spill box 10 enters accurate filter 7 by fresh water pump 9, purifying waste water of institute's output enters water quality on-line detector 6-1, through the detection of water quality on-line detector 6-1, if water quality reaching standard, then Open valve 14-3, valve-off 14-2, clear water enters filtered water tank 8, if water quality is not up to standard, and valve-off 14-3 then, Open valve 14-2, clear water returns spill box 10, and the water in the filtered water tank 8 can be directly as the rig water, and the medicament outlet conduit of chemicals dosing plant 4 is connected on the pipeline between black water preprocessor 3 and the coagulation thickner 5.

Claims

1. down-hole drilling water treatment device, described a kind of down-hole drilling water treatment device comprises black water collecting tank, black water preprocessor, chemicals dosing plant, coagulation thickner, water quality on-line detector, accurate filter, coal slime pressure filter, mine car, pump, spill box, filtered water tank, valve; It is characterized in that, after the black water that rig produces enters the black water collecting tank, by being pumped in the black water preprocessor, remove diameter greater than the particle of 0.5mm, pack into the mine car transportation of this part particle, enter the coagulation thickner through pretreated black water, black water after concentrated enters the coal slime pressure filter, pack into the mine car transportation of slime filter cake after the press filtration, produce filtrate water after the press filtration and return the coagulation thickner, the overflow clear water that the coagulation thickner produces enters accurate filter and carries out purifying treatment, water after the purification enters filtered water tank, for rig, water quality line detector is installed in coagulation thickner water outlet and accurate filter water outlet, and dosing mouth is on the pipeline between black water preprocessor and the coagulation thickner.
