Technical field
The utility model relates to a kind of drainage equipment, especially for the sewage drainage equipment that has high-concentration waste gas or toxic gas of heavy duty service environment, be applicable to the draining of the air-water separation of garbage loading embeading deep-well, abandoned mine well or organic solid waste anaerobic treatment Deep Underground.
Background technique
Traditional drainage equipment is all to use motor as driving power source, drive centrifugal or reciprocating machine to carry out work, when there is flammable explosive gas in operating environment, can easily cause burning or blast because line defct, Electric actuator produce the reasons such as electrical spark, make draining have potential safety hazard.
In garbage loading embeading deep-well, abandoned mine well, the deep-well that has high-concentration waste gas or toxic gas or organic solid waste anaerobic treatment Deep Underground operating environment, drainage equipment needs mounting point in the degree of depth of underground 10-30 rice, and the equipment such as common self-priming pump, membrane pump with pneumatic drive do not have so high water suction lift.
Adopt the drainage equipment of centrifugal principle work, because of outward appearance and build larger, cannot be placed in the narrow and small environment of working space, as small deep well, pipeline etc.
Common water-pumping/draining equipment is perishable in middle temperature organic acidity environment time, is not suitable for pump drainage deep under ground with the organic wastewater of high concentration or toxic gas.
Summary of the invention
The purpose of this utility model is to provide a kind of gas piston formula drainage equipment that can be used in the sewage that has high-concentration waste gas of heavy duty service environment.
The utility model is achieved in that
Gas piston formula drainage equipment comprise be arranged on down-hole column pump and and with the air-powered electromagnetic induction installation with compressed air, intake pipe and outlet pipe are arranged at described column pump pump housing top, as the sewage of high-concentration waste gas or the sewage of toxic gas, be rejected to the passage of well head outside, the pump body of described column pump is provided with center tube and passes top and connects intake pipe and outlet pipe; Described air-powered electromagnetic induction installation comprises solenoid valve, permanent magnets and unsteady level sensor, permanent magnets and unsteady level sensor are arranged on the center tube outer wall of the pump housing, it is outer and be connected with compressed air hose that solenoid valve is arranged on the center tube on pump housing top, column pump pump housing middle part is provided with into, gas supplementing opening, as the power source of moving up and down to air-powered electromagnetic induction installation, solenoid valve pressurized air gas outlet tube connects the entering of column pump, gas supplementing opening.
The above-described pump housing is cylindrical body or cuboid.
The utility model adopts pneumatic principle, utilizes float level sensor and control device induction height of water level, utilizes the switching of lever principle and permanent-magnet control valve door, thereby controls compressed-air actuated turnover, the object that reaches control apparatus operation and stop; The pressure producing by pressurized air is discharged liquid by drainage pipe, complete draining.Equipment pneumatic system and operating environment are isolated completely, can not bring the flammable explosive gas in operating environment into drainage system, thereby solve flammable explosive gas, leak and cause potential safety hazard.Equipment adopts resistant material making equipment, and equipment can be moved in 60 ℃ of following organic acidity environment.Equipment profile is exquisite, can insert in the narrow operating environment below diameter 200mm, is convenient to maintenance and changes.Equipment is adapted at existing operation in the environment of flammable explosive gas, can be used for the fields such as rubbish landfill gas collection, high concentrated organic wastewater, organic solid waste anaerobic treatment and comprehensive utilization.
The beneficial effects of the utility model are:
1, equipment pneumatic system and operating environment are isolated completely, can not bring the flammable explosive gas in operating environment into drainage system, guarantee security of operation.
2, utilize the level sensor sensed water level height that floats, utilize the switching of lever principle and permanent-magnet control valve door, thereby control compressed-air actuated turnover, the object that reaches control apparatus operation and stop.
3, adopt glass fibre reinforced plastics, stainless steel as equipment body material, can under the strong organic acid environment of 60% left and right, keep normal operation.
4, volume is small and exquisite, can be placed in pipeline or deep-well below diameter 200mm, and Operation and maintenance are convenient.
5, be adapted at existing operation in the environment that flammable explosive gas, liquid corrosion are strong, be mainly used in the utilization systems such as garbage loading embeading deep-well, abandoned mine well or organic solid waste anaerobic treatment Deep Underground, as the drainage equipment of air-water separation.

Embodiment
From Fig. 1 and Fig. 2, show:
Gas piston formula drainage equipment comprise be arranged on down-hole column pump and and with the air-powered electromagnetic induction installation with compressed air, intake pipe 1 and outlet pipe 8 are arranged at the pump housing 3 tops of described column pump, as the sewage of high-concentration waste gas or the sewage of toxic gas, be rejected to the passage of well head outside, the described pump housing 3 inside are provided with center tube 2 and pass top and connect intake pipe 1 and outlet pipe 8; Described air-powered electromagnetic induction installation comprises solenoid valve 6, permanent magnets 5 and unsteady level sensor 4, permanent magnets 5 and unsteady level sensor 4 are arranged on center tube 2 outer walls of the pump housing 3, it is outer and be connected with compressed air hose that solenoid valve 6 is arranged on the center tube 2 on the pump housing 3 tops, the pump housing 3 middle parts are provided with into, gas supplementing opening 7, as the power source of moving up and down to air-powered electromagnetic induction installation, solenoid valve 6 pressurized air gas outlet tubes connect the entering of column pump, gas supplementing opening 7.
The working principle of the utility model gas piston formula drainage equipment:
When liquid level is during higher than equipment intake pipe 1, waste liquid enters pump chamber 3 from intake pipe 1 through turnover water pipe 2, and the level sensor 4 that floats rises with liquid level, and promotion permanent magnet 5 is near solenoid valve 6.Solenoid valve 6 actions make pressurized air by air inlet and exhaust piper 7, enter the inner chamber of the pump housing 3, and the waste liquid of inner chamber is extruded well from outlet pipe 8 through turnover water pipe 2.
The interior liquid level of the pump housing 3 declines, and the level sensor 4 that floats drops to bottom thereupon, and permanent magnet 5 leaves solenoid valve 6, and solenoid valve 6 action closes compression air air inlet-outlet pipes 7, open outlet valve simultaneously and discharge by the pressurized air in pump chamber.
After pressurized air is discharged, the poor disappearance of equipment external and internal pressure, now liquid level as outer in equipment, still higher than equipment intake pipe 1, starts new round circulation by above-mentioned steps.
