Abstract
The utility model relates to the technical field of water pumps, in particular to an explosion-proof mine submersible pump which comprises an electric motor. A junction box is disposed at the upper end of the electric motor. Handles are disposed on two sides of the electric motor. A pump block is connected to the lower end of the electric motor and is coaxial with the electric motor. A junction box cover is disposed at the upper end of the junction box, an outgoing bucket is disposed at the left end of the junction box, and a junction board is disposed inside the junction box. An impeller is disposed inside the pump block and is fixed to the tail end of a rotary shaft of the electric motor, the right side of the pump block is provided with a water outlet, the bottom end of the pump block is connected with a base, an external ground terminal is arranged outside the base, and the base is a filter hood provided with a water inlet. The explosion-proof mine submersible pump is simple in structure and reasonable in design. The electric motor of the explosion-proof mine submersible pump is explosion-proof and can be coaxially integrated with the pump block to submerge in water for operation, and the explosion-proof mine submersible pump is adaptable to mine underground complex environments, and is especially safe and reliable for underground mines containing gas and coal dust.
Description
Technical field:
The utility model relates to the pump technology field, relates in particular to a kind of explosion-proof type mining diving 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 explosion-proof type mining diving pump is provided; 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.
The utility model technical problem to be solved adopts following technological scheme to realize.
A kind of explosion-proof type mining diving pump comprises motor, it is characterized in that: said motor upper end is provided with terminal box, and the motor both sides are provided with carrying handle, and the motor lower end connects the pump housing, and the pump housing is coaxial with motor; Said terminal box upper end is provided with connector cover, and the terminal box left end is provided with the outlet bucket, is provided with wire board in the terminal box; In the said pump housing impeller is set, pump housing right side sets out the mouth of a river, and pump housing bottom connects base, and chassis outer side is provided with external ground.
The mating face of said connector cover and terminal box is a flameproof joint.
Said motor bottom is provided with lower end cap, and the mating face of lower end cap and motor field frame is a flameproof joint.
Said impeller is fixed on the end of motor rotary shaft.
Said base is the filter cap that is provided with water intake.
The utility model is simple in structure, and is reasonable in design, and the motor of water pump processes that flame-proof type (dry type) and the pump housing are coaxial can to adapt to the complex environment under the mine for the one operation that pulls the plug, and under the mine that contains gas and coal dust, uses, and is especially safe and reliable.
