Description
Technical field
The utility model relates to a kind of Sewage treatment systems, particularly relates to a kind of for dredging the system of wastewater disposal pump.
Background technology
Sewage desulphurization system, is widely used in the industries such as chemical industry, mine, oil, metallurgy, and the protection of water resources has been played to vital role.Sewage desulphurization system is by recycle pump, industrial sewage to be got in thionizer at present, discharge after filtering through delaying.Find in actual use, the foreign material such as some mud, weeds easily get lodged in the lift pump place of sewage desulphurization system, cause sewage desulphurization system to be stopped up, and the lighter affects normal sweetening effectiveness, when serious, is forced to stop production.The usual way of at present sewage desulphurization system lift pump being dredged is artificial dredging, in artificial dredging process, must dismantle some main equipments, not only time-consuming but also require great effort.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, easy to operate, process and stop up the desulphurization system with backwashing function of successful.
A kind of desulphurization system with backwashing function of the utility model, comprising: high-pressure water tank, pipe connecting, lift pump, sewage lagoon; The water-in of described high-pressure water tank is connected with water outlet of water pump by pipe connecting, and the water-in of described lift pump immerses below the liquid level of sewage lagoon; The bottom of high-pressure water tank is provided with flowing water Valve, is provided with high-pressure water inlet hole near one end of water outlet of water pump, and described high-pressure water tank flowing water Valve is connected by pressure piping with lift pump high-pressure water inlet hole; In the middle of the pipe connecting that connects high-pressure water tank and lift pump, be provided with the valve that dams.
A kind of desulphurization system with backwashing function of the utility model, the water outlet of wherein said high-pressure water tank is connected with high-pressure hydraulic pump.
The desulphurization system that the utlity model has backwashing function is rationally used the foreign material such as power that high-pressure water tank the provides mud to lift pump precipitation to carry out back flush, can dredge stopping up lift pump very easily, dismantle any equipment without workman, quick, time saving and energy saving, successful.In the time using the utility model to dredge lift pump, retrograde current can be discharged from the water-in of lift pump in addition, and the current that drive in the wrong direction when discharge impact being positioned at the mud formation around of lift pump water-in in sewage lagoon, have removed the factor that causes lift pump to stop up.
Below in conjunction with accompanying drawing, the desulphurization system that the utlity model has backwashing function is described further.
Brief description of the drawings
Fig. 1 is the current schematic diagram of desulphurization system under normal operation condition that the utlity model has backwashing function;
Fig. 2 is the current schematic diagram of desulphurization system in the time of dredging lift pump that the utlity model has backwashing function.
Embodiment
As shown in Figure 1, a kind of desulphurization system with backwashing function, comprising: high-pressure hydraulic pump 1, high-pressure water tank 2, pipe connecting 3, lift pump 4, sewage lagoon 5, clean water basin 7.The water outlet of high-pressure hydraulic pump 1 is connected with clean pond 7 by pipeline, the water-in of high-pressure hydraulic pump 1 is connected with the water outlet of high-pressure water tank 2 by pipeline, the water-in of high-pressure water tank 2 is connected with lift pump 4 water outlets by pipe connecting 3, and is provided with the valve 6 that dams in the middle of pipe connecting 3.The water-in of lift pump 4 immerses below the liquid level of sewage lagoon 5; The bottom of high-pressure water tank 2 is provided with flowing water Valve 9, is provided with high-pressure water inlet hole near one end of lift pump 4 water outlets, and the flowing water Valve 9 of high-pressure water tank 2 is connected by pressure piping 8 with the high-pressure water inlet hole of lift pump 4.
The water (flow) direction of the desulphurization system that the utlity model has backwashing function under normal operation condition be as shown in Figure 1:
First close the flowing water Valve 9 of high-pressure water tank 2 bottoms, open the valve 6 that dams; Then the sewage in sewage lagoon 5 enters in high-pressure water tank 2 through lift pump 4, pipe connecting 3 under the effect of lift pump 4, and sewage is disposed to clean water basin 7 after the interior extension desulfurization of high-pressure water tank 2 is processed.
The water (flow) direction of the desulphurization system that the utlity model has backwashing function in the time of dredging lift pump as shown in Figure 2.
First close the valve 6 that dams, open the flowing water Valve 9 of high-pressure water tank 2 bottoms; And then the water in high-pressure water tank 2 flows into lift pump 4 and the mud in lift pump 4 pipelines is carried out to regressive erosion through flowing water Valve 9, the pressure piping 8 of high-pressure water tank 2 bottoms under High Voltage, until the pipeline of dredging lift pump 4.If the hydraulic pressure in high-pressure water tank 2 is still not enough to lift pump 4 to dredge, just open high-pressure pump 1, make high-pressure pump 1 further increase the pressure of high-pressure water tank 2 by pumps water, until dredge lift pump 4 pipelines.
The desulphurization system that the utlity model has backwashing function is rationally used the foreign material such as power that high-pressure water tank 2 the provides mud to lift pump precipitation to carry out back flush, can dredge the lift pump 4 stopping up very easily, dismantle any equipment without workman, quick, time saving and energy saving, successful.In addition in the time using the utility model to dredge lift pump 4, retrograde current can be discharged from the water-in of lift pump 4, retrograde current when discharge form impact to being positioned at lift pump 4 water-ins mud around in sewage lagoon, have removed the foreign material that easily cause lift pump to stop up.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
