Description
Technical field
The utility model relates to field, power station, particularly relates to shaft bottom, a kind of power station excretion machine.
Background technology
Power station is the integration engineering facility that water can be converted to electric energy, generally comprises the reservoir and Diversion system of hydropower station, power plant building, electromechanical equipment etc. that are formed by dash, outlet structure escape works.The high water level water of reservoir flows into factory building promotion turbine-generator units through diversion system and sends electric energy, then through step-up transformer, switching station and transmission line of electricity input electrical network.In power station, seepage collecting well is mainly collected from water-turbine top cover draining and factory building seepage drainage everywhere.In many rivers, due to the destruction of upstream, river basins vegetation.Unit flow passage components wearing and tearing aggravation, rotating wheel upper leak-proof ring gap expands rapidly, and top cover upper cavity pressure significantly rises, and causes water seal wearing and tearing and water leakage significantly to increase.Flood tide water brings the impurity such as a large amount of quartz sands and diamond dust, and these silts deposit rapidly in collecting well on the one hand, and blocking drainage pump intake, has a strong impact on the normal operation of water pump.On the other hand, silt is evacuated to downstream tail water by drainage pump, when water pump vane, bearing and sealing etc. lose, due to quartz sand and diamond dust extreme hardness, causes water pump operation to occur the problems such as seal failure, pump shaft is levigate in a short time.In order to desilting, all have to annual flood season organize regularly a large amount of manpower to carry out desilting to collecting well.In order to reduce water level in well during desilting, drainage pump adopts manual mode start and stop, careless slightly, just may cause drainage pump idle running damage and motor damage.Therefore need to provide a kind of excretion machine, can efficiently dirt be discharged.
Summary of the invention
The utility model, in order to overcome deficiency of the prior art, provides shaft bottom, a kind of power station excretion machine, by combinationally using of dredge pump, agitator and exhaust plant, improves its filth-discharging effect.
The utility model is achieved through the following technical solutions:
A kind of shaft bottom, power station excretion machine, comprise the dredge pump be placed in shaft bottom, one end of described dredge pump connects sand discharge pipe, the husky mouth of suction of the other end is positioned at center, shaft bottom, this excretion machine also comprises and is arranged on agitator in shaft bottom and exhaust plant, and described agitator comprises shaft and is arranged on the paddle on shaft; Described exhaust plant comprises exhaust pump and connects the stack of exhaust pump, stretches in the shaft bottom in power station in described stack.
As optimal technical scheme of the present utility model, one section that stretches in shaft bottom, power station in described stack offers steam vent.
As optimal technical scheme of the present utility model, described stack is provided with control valve I.
As optimal technical scheme of the present utility model, described sand discharge pipe is provided with control valve II.
Compared with prior art, the beneficial effects of the utility model are: the utility model is combinationally used by dredge pump, agitator and exhaust plant, wherein, gas is blown into shaft bottom by exhaust plant, dispel silt and make itself and water mixing, stirred by agitator, make silt and water mixing even, by dredge pump, impurity is discharged from sand discharge pipe, improve its contaminant removal effectiveness.

In figure: 1-dredge pump; 2-sand discharge pipe; 3-shaft; 4-paddle; 5-exhaust pump; 6-stack; 7-steam vent; 8-control valve I; 9-control valve II.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Shaft bottom, described a kind of power station excretion machine, comprise the dredge pump 1 be placed in shaft bottom, one end of described dredge pump 1 connects sand discharge pipe 2, the husky mouth of suction of the other end is positioned at center, shaft bottom, this excretion machine also comprises and is arranged on agitator in shaft bottom and exhaust plant, the paddle 4 that described agitator comprises shaft 3 and is arranged on shaft 3; Described exhaust plant comprises exhaust pump 5 and connects the stack 6 of exhaust pump 5, and stretch in the shaft bottom in power station in described stack 6, one section that stretches in shaft bottom, power station in described stack 6 offers steam vent 7.By combinationally using of dredge pump, agitator and exhaust plant, wherein, gas is blown into shaft bottom by exhaust plant, carry out purging to shaft bottom silt to stir, silt is mixed with water as far as possible, is stirred by agitator, make silt and water mixing even, by dredge pump, impurity is discharged from sand discharge pipe, improve its contaminant removal effectiveness.In the present embodiment, what sand discharge pipe 2 adopted is stainless steel tube, and what stack 6 adopted is flexible pipe.
Described stack 6 is provided with control valve I 8, and described sand discharge pipe 2 is provided with control valve II 9, and described control valve I 8 and control valve II 9 are manual modulation valve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
