Pit water precipitation grease removal treatment device
Technical field
The utility model relates to a kind of equipment for treating water from mine, is specifically related to a kind of pit water precipitation grease removal treatment device.
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, in coal mining process, there is a large amount of underground water, but owing to containing a large amount of silt, mud and mineral oil in water, normally cannot use, bring a lot of trouble to daily coal work.
Utility model content
The utility model 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, precipitate and separate deoiling effect is good, pit water precipitation pretreatment unit that running cost is low.
For solving the problems of the technologies described above; the technical scheme that the utility model adopts is: pit water precipitation grease removal treatment device; comprise precipitation separation device and oil removal plant; described precipitation separation device comprises precipitate and separate case, inclined tube group, water inlet pipe and rising pipe; the top of described precipitate and separate case is provided with toroidal membrane; the bottom of described toroidal membrane is provided with inclined tube group; the top of toroidal membrane is provided with water leg; the top of described precipitate and separate case is provided with water inlet pipe and rising pipe, and described rising pipe is connected with water leg;
Described oil removal plant comprises oil removing casing, water inlet water distributing pipe, water outlet, oil outlet and cursory, the middle part of described oil removing casing is provided with into water water distributing pipe, described water inlet water distributing pipe is connected with rising pipe, oil removing casing top be provided with oil outlet and can fluctuate cursory, described cursory bottom is provided with flexible oil header, described flexible oil header is connected with oil outlet, and oil removing lower box is provided with water outlet, and oil removing casing top is provided with venting port.
Preferably, the bottom of described precipitate and separate case is pyramidal structure, and the top of precipitate and separate case is provided with shore pipe, and described shore pipe extends to the bottom of precipitate and separate case.
The beneficial effect that the utility model is compared with prior art had is: the utility model is simple and reasonable for structure, production cost is low, operate steadily, easily operate, can fast the mud in water be separated, be precipitated, simultaneously except the mineral oil in anhydrating, compact construction, floor space are little.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1; pit water precipitation grease removal treatment device; comprise precipitation separation device and oil removal plant; described precipitation separation device comprises precipitate and separate case 1, inclined tube group 2, water inlet pipe 3 and rising pipe 4; the top of described precipitate and separate case 1 is provided with toroidal membrane 5, and the bottom of described toroidal membrane 5 is provided with inclined tube group 2, and the top of toroidal membrane 5 is provided with water leg 7; the top of described precipitate and separate case 1 is provided with water inlet pipe 3 and rising pipe 4, and described rising pipe 4 is connected with water leg 7;
Described oil removal plant comprises oil removing casing 8, water inlet water distributing pipe 9, water outlet 10, oil outlet 11 and cursory 12, the middle part of described oil removing casing 8 is provided with into water water distributing pipe 9, described water inlet water distributing pipe 9 is connected with rising pipe 4, oil removing casing 8 top is provided with oil outlet 11 and can fluctuate cursory 12, the described bottom of cursory 12 is provided with flexible oil header 13, described flexible oil header 13 is connected with oil outlet 11, oil removing casing 8 bottom is provided with water outlet 10, and oil removing casing 8 top is provided with venting port 14.
In actual use, pit water directly enters in precipitate and separate case 1 by water inlet pipe 3, the water outlet of water inlet pipe 3 is between precipitate and separate case 1 and toroidal membrane 5, toroidal membrane 5 effectively can cushion the surging force of water inlet, make the water in precipitate and separate case 1 more steady, conveniently carry out precipitate and separate; After water enters precipitate and separate case 1, water enters separation by inclined tube group 2, sludge settling is deposited in the bottom of precipitate and separate case 1 gradually, water through precipitate and separate enters in water leg 7, flowed out by rising pipe 4, enter in oil removing casing 8, water inlet water distributing pipe 9 adopts and arrange multiple through hole on body, carry out water distribution, according to profit relative density difference, oil-in-water particle travels up to oil removing casing 8 top with certain speed to be assembled, namely bubble through the water column above, water then moves downward, and enters oil removing casing 8 bottom, thus achieves oily water separation; Wherein, by the sedimentation of certain hour, crude oil is gathered in the different heights in the certain limit above the water surface, cursory 12 swim in oil removing casing 8 internal liquid level on the surface, and fluctuate with the height change of liquid level, cursory 12 fluctuate while the crude oil of sedimentation oil removing casing 8 top different aspects is fully drawn, and to be collected by the flexible oil header 13 be connected with cursory 12, and discharged by oil outlet 11.
In addition, the bottom of precipitate and separate case 1 adopts taper structure design, conveniently carries out rapid precipitation, the top of precipitate and separate case 1 is provided with shore pipe 6 simultaneously, shore pipe 6 extends to the bottom of precipitate and separate case 1, and mud can carry out spoil disposal by shore pipe 6, clears up also convenient.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; but the utility model is not limited to above-described embodiment; in the ken that those of ordinary skill in the art possess; various change can also be made obtaining under the prerequisite not departing from the utility model aim, also should be considered as protection domain of the present utility model.
