Description
Technical field
The present invention relates to a kind of coal mine waste water disposal device, be specifically related to a kind of waste-water from coal mine pretreatment unit.
Background technology
Along with the development of mine equipment equipment, coal winning machinery level of automation also improves constantly.Hydraulic support, as most important coal excavation apparatus, plays more and more important effect in shaft production.At a large amount of emulsified water that uses as in the hydraulic support of working medium, the quality of water, composition for hydraulic support normal operation and have very large impact work-ing life.
At present, coal mining produces a large amount of waste water, and after sinking to the bottom separation, still do not reach the standard of acceptable industrial water, water-quality ratio is poor.Under such conditions, because water quality reason causes the damage of the coal excavation apparatus particularly cooling system of electric motor, the hydraulic unit such as valve group, screw block, column of hydraulic support to roll up.Cause the maintenance cycle of equipment and working life to shorten, even cannot normally use.This not only adds maintenance of equipment machine maintenance workload, the consequent is the increase that maintenance of equipment accessory drops into, and finally causes the increase of mining costs.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved there is provided a kind of simple and reasonable for structure, easily operates, the waste-water from coal mine pretreatment unit that good filtration effect, running cost are low.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: waste-water from coal mine pretreatment unit, comprise the first tank body, the first water inlet pipe, the first rising pipe and porous plate, described tank body top is provided with water inlet pipe, and bottom is provided with rising pipe, and its inside is provided with filter material layer and porous plate, described filter material layer is arranged on the top of porous plate, described rising pipe extends to the inside of tank body, and striking plate is stamped at the top of rising pipe, and the top of described tank body is also provided with vapor pipe.
Described porous plate is provided with water cap.
Described rising pipe is provided with stopple coupon, and the bottom of described stopple coupon is provided with sampling groove.
The beneficial effect that the present invention is compared with prior art had is: the present invention is simple and reasonable for structure, and production cost is low, operate steadily, easily operate, good filtration effect, and compact construction, floor space are little.
