Abstract
The utility model discloses a drawing device for groundwater. The drawing device comprises a pipe drawn from underground and a support fixed on the ground, wherein a water tank is fixedly installed on the support, a hole is arranged at the bottom of the water tank, the upper end of the pipe penetrates through the hole at the bottom of the water tank and extends to the upper portion in the water tank, the upper end of the water tank is provided with an air inlet and an air outlet respectively, a water outlet is arranged at the bottom of the water tank and connected with a water discharging pipe, and a valve is installed in the water discharging pipe. According to the drawing device, the structure is reasonable, groundwater is drawn to the water tank by using the air pressure principle, the fact that the water contains sediment caused by pumping through a water pump is avoided, the follow-up sedimentation and purification treatment are omitted, the cost is saved, and the normal production schedule is guaranteed.
Description
Technical field
The utility model relates to a kind of equipment for pumping ground water.
Background technique
In the sugar industry field, water is common solvent, and the water in each production process is from underground water.In the prior art, the draw-out device of underground water comprises the water pipe that passes into below the earth's surface, and water pump is installed in the water pipe.By water pump underground water is drawn up, can carry a large amount of silt but draw up in the next water, need further to do to use after precipitation and the purified treatment, increased cost, also affected the progress of production.
The model utility content
The purpose of this utility model provides a kind of equipment for pumping ground water, by the draught head principle with groundwater mining in water tank, and do not contain silt in the water.
The technical solution of the utility model is as follows:
A kind of equipment for pumping ground water, include from the pipeline of drawing below the earth's surface and the support that is fixed on the earth's surface, it is characterized in that: be installed with water tank on the described support, the bottom of described water tank is provided with perforate, the upper end of described pipeline is passed the perforate of water tank bottom and is extended to the interior top of water tank, the upper end of described water tank is respectively equipped with inlet, outlet, described inlet, outlet is respectively by tracheae external gas source and vacuum pumping pump, the bottom of described water tank is provided with water outlet and is connected with outlet pipe, in the described outlet pipe valve is installed.
Described equipment for pumping ground water is characterized in that: the connecting part of described pipeline and water tank bottom perforate is provided with seal ring.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, by the draught head principle with groundwater mining in water tank, avoided water pump to extract the phenomenon that causes containing in the water silt, saved post precipitation and purified treatment operation, saved cost, ensured normal manufacturing schedule.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of equipment for pumping ground water, include from the pipeline 1 of drawing below the earth's surface and the support 2 that is fixed on the earth's surface, be installed with water tank 3 on the support 2, the bottom of water tank 3 is provided with perforate, the upper end of pipeline 1 is passed the perforate of water tank 3 bottoms and is extended to top in the water tank 3, the upper end of water tank 3 is respectively equipped with inlet, outlet 4,5, inlet, outlet 4,5 is respectively by tracheae 9 external gas sources and vacuum pumping pump, the bottom of water tank 3 is provided with water outlet 6 and is connected with outlet pipe 7, and valve 8 is installed in the outlet pipe 7.
In the utility model, pipeline 1 is provided with seal ring with the connecting part of water tank 2 bottom opening.
At first vacuum pumping pump work, gas in the water tank 3 is 5 discharges through the air outlet, under the effect of pressure difference, air pressure in the water tank 3 reduces, when the air pressure in the water tank 3 is lower than underground water hydraulic pressure, underground water is entered in the water tank 3 by pipeline 1, after the water level in the water tank 3 rises to certain altitude, source of the gas passes into air by tracheae 9 in water tank 3, air pressure in the water tank 3 rises gradually, and when when the air pressure in the water tank 3 is higher than underground water hydraulic pressure, underground water is no longer entered in the water tank 3 by pipeline 1, this moment Open valve 8, the water in the water tank 3 are discharged through outlet pipe 7 under the condition of high hydraulic pressure.
After the discharge in the water tank 3, constantly circulate according to said process again, can finish the extraction work of underground water.
Claims (2)
1. equipment for pumping ground water, include from the pipeline of drawing below the earth's surface and the support that is fixed on the earth's surface, it is characterized in that: be installed with water tank on the described support, the bottom of described water tank is provided with perforate, the upper end of described pipeline is passed the perforate of water tank bottom and is extended to the interior top of water tank, the upper end of described water tank is respectively equipped with inlet, outlet, described inlet, outlet is respectively by tracheae external gas source and vacuum pumping pump, the bottom of described water tank is provided with water outlet and is connected with outlet pipe, in the described outlet pipe valve is installed.
