Abstract
The invention discloses an antifreeze and icebreaking process for coal slime settling tanks in non-extremely-cold regions. The antifreeze and icebreaking process includes respectively laying two icebreaking pipes on two sides of each coal slime settling tank, and uniformly forming a plurality of holes on a side of each icebreaking pipe; arranging the holes in the icebreaking pipes in 45-degree positions away from the directions of tank walls when the icebreaking pipes are laid; arranging submersible pumps at junctions of the coal slime settling tanks and settled water tanks, connecting the icebreaking pipes with the submersible pumps, boosting pressures of settled water by the aid of the submersible pumps, spraying the water to the water surfaces near the inner walls of the coal slime settling tanks via the holes in the icebreaking pipes from bottom to top and keeping the water surfaces of the coal slime settling tanks in fluctuation states on the premise that settling effects are unaffected so as to realize antifreeze and icebreaking effects. The icebreaking pipes are arranged at positions below the water surfaces of the tank walls by the distances of 200-300 mm. The antifreeze and icebreaking process has the advantages that enclosing structures on the upper portions of the coal slime settling tanks are omitted, and accordingly one-time investment can be reduced; low-flow and low-lift water pumps are used as the submersible pumps, accordingly, energy consumption of the antifreeze and icebreaking process is far lower than energy consumption of heating and heat-insulation measures, and the running cost can be reduced; the antifreeze and icebreaking process has excellent economical and environmental protection benefits.

For achieving the above object, the present invention provides following technical scheme:
The antifreeze technique that opens ice of slurry pond of a kind of non-extremely cold area, comprises the following steps:
(1) being positioned at 200～300mm place below the pool wall water surface in slurry pond both sides and lay the pipe that opens ice respectively, the side of the pipe that opens ice uniformly has several holes；Lay this have hole open ice pipe time so that the hole opened ice on pipe is in 45 ° of positions away from pool wall direction；
(2) along the water (flow) direction of slurry pond, end at slurry pond is connected to a heavy rear pond, intersection at slurry pond with heavy rear pond is provided with immersible pump, by opening ice, pipe one end near heavy rear pond is connected with immersible pump, by immersible pump, the heavy rear water in slurry pond is boosted, again through the hole opened ice on pipe from bottom to top to water surface water spray near slurry pond inwall, the slurry pond water surface is made to remain fluctuation status under the premise not affecting sedimentation effect, thus reaching the freeze proof effect opened ice.
As the further scheme of the present invention: described in the pipe that opens ice be laid on 250mm place below the pool wall water surface.
As the further scheme of the present invention: described in open ice pipe for flexible pipe.
As the further scheme of the present invention: described in the hole opened ice on pipe be positioned on straight line.
As the further scheme of the present invention: described immersible pump is low discharge low-lift pump.
As the further scheme of the present invention: the number of described immersible pump is 1～2.
Compared with prior art, the invention has the beneficial effects as follows:
1, present invention eliminates slurry pond top building enclosure, greatly reduce one-time investment；
2, the present invention adopts low discharge low-lift pump as immersible pump, to heavy rear water boosting, the precipitation zone water surface is made to produce fluctuation by the pipe that opens ice, thus reaching the freeze proof effect opened ice, the energy consumption of water pump used, well below warm keeping measure, greatly reduces operating cost；
3, the present invention had both met the requirement of the waste water environmental protection treatment reuse of promotion now, decreases again cost, saves the energy, has good economic benefit and environmental benefit.
Accompanying drawing explanation
Fig. 1 is the slurry pond structural representation of the embodiment of the present invention；
Fig. 2 is the perforate schematic diagram of the pipe that opens ice that the embodiment of the present invention adopts.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1～2, in the embodiment of the present invention, the antifreeze technique that opens ice of slurry pond of a kind of non-extremely cold area, comprise the following steps:
(1) it is positioned at 200～300mm place below the pool wall water surface in slurry pond both sides and lays the pipe that opens ice respectively, the open ice side of pipe uniformly has several apertures, these apertures are positioned on straight line, and distance between adjacent aperture is equal, preferably, the pipe that opens ice is flexible pipe, and this pipe that opens ice is laid on 250mm place below the pool wall water surface；Lay this have hole open ice pipe time so that the hole opened ice on pipe is in the direction away from pool wall, and meanwhile, the hole being held on is in 45 ° of positions away from pool wall direction；
