Description

A device for fully utilizing domestic wastewater

technical field

The utility model relates to a water-saving device, in particular to a device for fully utilizing domestic waste water.

Background technique

Without water, there is no life. Water is no longer an "inexhaustible" natural resource, and water has become less and less. According to estimates, the total amount of fresh water resources in my country is 2.7 trillion cubic meters, ranking sixth in the world, but the per capita water volume is only 1/4 of the world's per capita share, ranking 110th in the world. At present, there are more than 200 cities in my country that lack water. Beijing suffers from a water shortage of more than 1 billion cubic meters every year, and the groundwater level has dropped to more than 30 meters in some places. Shenzhen is short of at least 100,000 cubic meters of water every day, and there has been a "water shortage".

Contents of the invention

The technical problem to be solved by the utility model is to provide a device for fully utilizing domestic wastewater.

In order to solve the problems of the technologies described above, the technical solution of the utility model is:

A device for fully utilizing domestic wastewater, including a toilet tank, a water tank for containing domestic wastewater, and a water pipe, and a high-level water storage tank with a liquid level sensor. The domestic wastewater in the tank is filtered and sucked in by a self-priming pump The high-level water storage tank, the downpipe of the high-level water storage tank is connected to the water tank of the toilet, and the tap water pipe is connected with the downwater pipe through the solenoid valve,

It also includes a controller: when the liquid level sensor detects that the high water storage tank is lower than the preset water level lower limit, start the self-priming pump, if the water level does not change for 3 seconds, turn off the self-priming pump, if the detected water level is still At the lower limit of the water level, open the solenoid valve for 60 seconds and then close it to supply tap water.

The domestic waste water contained in the tank is pumped into the high-level water storage tank through the self-priming pump for storage. The water in the toilet water tank comes from the downpipe of the high-level water tank. The utility model can make full use of domestic waste water and save water resources.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a schematic diagram of the utility model.

In the figure: 1 liquid level sensor, 2 high-level water storage tank, 3 water pipe, 4 toilet water tank, 5 solenoid valve, 6 water pipe, 7 water tank, 8 water suction pipe, 9 self-priming pump, 10 water outlet pipe.

Detailed ways

As shown in Figure 1, a kind of domestic waste water fully utilizes the device, comprises the water tank 4 of toilet, the tank 7 that holds domestic waste water and running water pipe 6, also comprises the high level water storage tank 2 that is provided with liquid level sensor 1, in the said tank After being filtered, the domestic waste water is pumped into the high-level water storage tank through the water suction pipe 8, the self-priming pump 9 and the water outlet pipe 10. The sewer pipe 3 of the high-level water storage tank is connected to the water tank of the toilet, and the tap water pipe is communicated with the sewer pipe through the solenoid valve 5. .

It also includes a controller: when the liquid level sensor detects that the high water storage tank is lower than the preset water level lower limit, start the self-priming pump, if the water level does not change for 3 seconds, turn off the self-priming pump, if the detected water level is still At the lower limit of the water level, open the solenoid valve for 60 seconds and then close it to supply tap water.
