[0002] Most of the domestic water in the family is disposable water, which is discharged into the sewer after use, so that the precious water resources are not fully utilized, which not only wastes resources and increases sewage discharge, but also increases the economic burden of society and families
The domestic waste water filter device invented by Liu Wei, application number 201610576941.9, includes a water storage tank, a water pipe, and a sewage inlet. When the filter screen needs to clean the filter box, turn on the switch of the water pipe, adjust the nozzle on the cleaning device, clean it, and then turn on the sewage It needs to be cleaned manually, which is troublesome

Embodiment Construction
[0011] Such as figure 1 As shown, the waste water inlet pipe 2 and the running water pipe 3 are installed on the water storage tank 1, and the drum 4 is installed in the water storage tank 1, the waste water inlet pipe 2 communicates with the bottom of the drum 4, and the filter screen 5 is set on the wall of the drum 4 . A normally closed electromagnetic valve 6 is installed in the water storage tank 1 , and the water inlet of the normally closed electromagnetic valve 6 communicates with the tap water pipe 3 . Install the connecting pipe 7 on the top of the drum 4 to pass through the top of the drum 4, the outlet of the normally closed solenoid valve 6 communicates with the outer end of the connecting pipe 7, and install the flushing head at the outlet of the connecting pipe 7 in the drum 4 8. It can rotate 360 degrees around the water outlet of the connecting pipe 7. The flushing head 8 corresponds to the position of the filter screen 5. The water outlet of the flushing h...

The invention discloses a household wastewater filtering device. The device comprises a water storage tank, a wastewater inlet pipe, a tap water pipe, a filter, an overflow pipe, a tap water inlet pipe and a normally-closed electromagnetic valve, wherein a water inlet of the normally-closed electromagnetic valve communicates with the tap water inlet pipe, a flushing head communicates with the normally-closed electromagnetic valve, a water level sensor is installed on the filter, a relay is installed in the water storage tank, the water level sensor is connected into an input loop of the relay, the normally-closed electromagnetic valve is connected into an output loop of the relay, an inverted U-shaped pipe is mounted in the water storage tank, one end of the inverted U-shaped pipe communicates with the overflow pipe, and the other end of the inverted U-shaped pipe communicates with the inner bottom of the filter. According to the household wastewater filtering device, when a filter screen is blocked and the water level in a filter barrel rises, due to the effect of the inverted siphon, waste water is discharged out of the water storage tank, the water level drops, the input loop of the relay is connected, the normally-closed electromagnetic valve is opened, and water in the tap water pipe flows to the flushing head through the normally-closed electromagnetic valve to flush the filter screen.
Description
technical field [0001] The invention relates to the field of household wastewater utilization, in particular to a household wastewater filter device. Background technique [0002] Most of the domestic water in the family is disposable water, which is discharged into the sewer after use, so that the precious water resources are not fully utilized, which not only wastes resources and increases sewage discharge, but also increases the economic burden on society and families. The domestic waste water filter device invented by Liu Wei, application number 201610576941.9, includes a water storage tank, a water pipe, and a sewage inlet. When the filter screen needs to clean the filter box, turn on the switch of the water pipe, adjust the nozzle on the cleaning device, clean it, and then turn on the sewage It needs to be cleaned manually, which is troublesome. Contents of the invention [0003] The purpose of the present invention is to provide a domestic waste water filtering dev...
