Water treatment device for teachers invented in Kunming University can save 2 tons of water per month

Xu Wei invented the schematic diagram of the working principle of the water treatment device in the home.

“My invention is to save water without changing our living habits.” Sewage is poured into a water tank, and the switch is lightly pressed. Within a few minutes, the sewage is purified and flows into the tank. You can flush the toilet. According to the inventor Xu Wei, a teacher at the Kunming Metallurgy College, his family water treatment unit can save at least 2 tons of water every month.

Less than 10 minutes when filtering a pot of water

This set of equipment is divided into three parts: a collection tank, a control center and a high water tank. The vegetable washing, washing, washing, and bathing water are piped together in a low level water collecting tank with a filter net.

"My control device is divided into automatic and manual, usually only need to tune into automatic." Xu Wei said that when the water in the collection tank reaches a certain height, the pump will automatically start to pump the water to the ground There are two meters high in the water tank. There is a filter at the entrance of the high water tank, which can filter impurities. The water tank contains the water treatment flocculant. When the water pump starts to flow, it will automatically add the flocculant. The purified water can reach the national second class water standard. Connect the water inlet pipe of the toilet directly to the water outlet of the high water tank and flush the toilet with the water flowing out.

The reporter saw that pouring a pot of vegetable water into a collecting tank to available water was only less than 10 minutes, and the water flowing out of the high tank was clearly clear. Under the high water tank is also provided with a drain valve and outlet, which can regularly remove dirt and water mopping.

“The current average monthly water consumption per household in Kunming is about 7 tons, of which 40% of the water comes from toilets flushing toilets. Although the relevant manufacturers have already produced water-saving toilets, water-saving toilets need 6 per time. This is also a waste.” Xu Wei said that he felt that as long as the toilet water saving measures can save a lot of water. Although many residents have come up with a scoop rinse, flushing with a scoop rinse not only does not clean it, but it also changes the daily habits of people working on the locks. His own set of equipment has a low-power pump. The pump has a power of 13.5 watts. It operates for half an hour a day and consumes electricity for four months. It is worthwhile to save at least 8 tons of water for the cost of electricity once.

"My equipment is limited to home use. If it is used in a community, it will not only occupy a large area, it will also consume a lot of resources." Xu Wei said.

Invented device has been declared national patent

In fact, the water treatment device in the home is just one of Xu Wei’s many inventions. Since he started teaching at Kunming Metallurgical College, he was very keen on inventions and creations. “Intelligent fly traps” and “Earthquake simulation escape devices” are all examples. It's his hand. Xu Wei said that he is teaching the mechanical design profession and engaging in inventions and creations. He wants to do practical things for the citizens with what he has learned. In addition, students participate in each of these projects. Through their own words and deeds, students are taught to use what they have learned in practice. After graduation, they will find a satisfactory job.

According to Xu Wei, the entire invention took only one month. From a practical point of view, the monthly water consumption of their homes was 7 tons, and the current monthly water consumption was 5 tons.

“Actually, I invented the water treatment device in the family to see the severe drought conditions in Kunming. The water flow from the river channel is generally low, the soil moisture is getting worse, the water supply is seriously inadequate, and people and livestock are extremely difficult to drink. We must try our best to save water. Xu Wei said that he invented the water treatment device in the family to do his part to save water and promote people’s water-saving awareness, so that more people would care and participate in water conservation and come up with more festivals. Water ideas and invent more water-saving equipment.

At present, water treatment devices in the home have been declared national patents. In addition, in view of the serious waste of water in the car wash, Xu Weizheng is considering inventing a set of water treatment equipment that meets the needs of the car wash to reduce the amount of water used by the car wash.
