The structure of the mine small pneumatic immersible pump is simple, the design is reasonable, and the mine small pneumatic immersible pump is suitable for pumping sewage containing coal slag, silt and other noncorrosive solids in medium in underground places with the danger of methane and coal dust explosion in coal mines, can be adapted to the complex environment under a mine, and is particularly safe and reliable when being used in a mine with gas and coal dust.
Description
Technical field:
The utility model relates to the pump technology field, relates in particular to a kind of mining little pneumatic sump pump.
Background technique:
Water under the mine is mainly from Atmospheric precipitation, surface water, aquifer water, tomography water and old empty ponding, and in the mine that uses hydraulic flushing method, hydraulic mining method exploitation, mine water also comprises some waste water that pour in mine.Swallet has been dissolved many mineral substance in the process of flowing of down-hole, also contain simultaneously the impurity such as ickings, quicksand of some.Therefore, the general clear water of mine water proportion is big, when 15 ℃ of water temperatures, is 1015～1025kg/m
3The impurity that swallet contains is a lot, and the particle of state of suspension is wherein arranged, easy abrasion water pump part.Also contain free acid in the swallet, its content shows the acid intensity of water, and acidity is big more, and is just big more to water pump and corrosion of pipe effect.Generally acid degree is described by pH value in the water.Existing nowadays general de-water is to adopt common submersible pump to carry out the drainage works under the mine.Yet along with the development of China's mining industry, increasingly high to the method requirement of draining, common submersible pump has satisfied not people's requirement.
The model utility content:
The utility model technical problem to be solved is to overcome the defective of existing technology; A kind of mining little pneumatic sump pump is provided; The mining pneumatic submersible pump be a kind of be medium with pressurized air, get into turbine rotation work done through jet pipe, pump shaft high speed rotary thereupon drives the pump impeller draining.The mining pneumatic submersible pump can adapt to the complex environment under the mine, uses at the mine that contains gas and coal dust, and is especially safe and reliable.
The utility model technical problem to be solved adopts following technological scheme to realize.
A kind of mining little pneumatic sump pump comprises pneumatic part and pump housing part, it is characterized in that: said pneumatic part is connected the upper end of pump housing part through transmission shaft; Said pneumatic part comprises outer cover, and the outer cover upper end is provided with carrying handle, and the outer cover right side is provided with the air intake mouth; The outer cover left side is provided with the mouth that leaks informaton, and is provided with rotor assembly in the outer cover, and rotor assembly is connected the transmission shaft upper end; The said pump housing partly comprises spiral case and base; Spiral case is connected the base upper end, is provided with impeller in the said spiral case and is connected the transmission shaft lower end, and the spiral case right side is provided with water outlet.
Said base is the filter cap that is shaped on the water inlet.
Said air intake mouth outer wall is provided with the outside thread that connects airduct.
Said water outlet outer wall is provided with the fixing tooth that connects water pipe.
The utility model is simple in structure; Reasonable in design; Being applicable to has methane and coal dust explosion hazard property occasion under the coal mine, contain the sewage liquid of non-corrosive solid matters such as cinder, silt in the fed sheet of a media, can adapt to the complex environment under the mine; Under the mine that contains gas and coal dust, use, especially safe and reliable.
