Abstract

The utility model relates to a water storage tank capable of recycling waste water, which belongs to the category of sanitary ware. It is used in the bathroom, used in combination with a washbasin, and connected with a toilet water storage tank. It flows into this water tank and is used as the water supply source of the water storage tank of the toilet after being pressurized. The top cover of the water storage tank is a sealed float that can move up and down. Like a piston, the float is equipped with a spring to pressurize the water in the water tank. The water port is connected with a one-way valve that can only flow out but not in. A sewage outlet is provided at the lower end of the water tank to be connected with a ball valve, and an overflow outlet is provided at the upper end to be connected with the sewer. It can meet the needs of secondary utilization of domestic wastewater and achieve the purpose of saving water.

Description

A water storage tank that can recycle waste water

technical field

The utility model relates to a water storage tank which can collect waste water used for laundry and face washing, and use the waste water for secondary use such as flushing toilets, which belongs to the family sanitary ware category. It is used in conjunction with the washbasin and connected with the toilet water storage tank, and is a waste water storage device used in the toilet. It can meet the need for secondary utilization of domestically available wastewater and achieve the purpose of saving water.

Background technique

At present, my country's groundwater resources are in short supply, especially in big cities, where water supply is becoming more and more tense, and now more than 90% of units and households use clean tap water to flush toilets, while used waste water such as laundry and face washing is wasted. Even if there are toilets available for flushing with waste water on the market today, due to the high position of the water storage tank, the drainage of the washbasin is difficult and the water storage capacity is small, it is inconvenient to use and difficult to transform, and it is difficult to promote.

Contents of the invention

The purpose of this utility model is to overcome the above disadvantages, to provide a device that can collect the waste water used for laundry and face washing, and its position can be lower than that of the water storage tank of the toilet, the capacity is large, and it can be pressurized to ensure the flushing water. And it is easy to transform the existing toilet into flushing with waste water.

The utility model achieves the above purpose through structural design. The top cover of the water storage tank is a sealed float that can move up and down. Like a piston, the float is equipped with a spring, which can pressurize the water in the water tank. The water inlet of the water tank is connected to There is a one-way valve that can only flow in but not flow out and is connected with the washbasin drain, and the water outlet is connected with a one-way valve that can only flow out but not in. A sewage outlet is provided at the lower end of one side of the water tank to be connected with a ball valve, and an overflow port is reserved at the upper end of the same side to be connected with the sewer.

The beneficial effect of the utility model is that not only the waste water used for laundry and face washing can be collected, but also the collected waste water can be pressurized as toilet flushing water, which is energy-saving, environment-friendly and convenient to use.

Detailed ways

As shown in Figure 1, the water inlet valve 1 is connected to the water inlet of the water tank. The waste water used for laundry and face washing flows into the water tank through the water inlet valve 1. The water inlet valve 1 is a one-way valve, which can prevent the water in the water tank from flowing backwards. The box body 2 is the core for storing waste water. The top cover 3 is placed above the box body. The top cover is in sealing contact with the box body and can move freely up and down. The top cover is made of waterproof and lightweight material. Clamp 4 is fixed on the wall near this water storage tank, so that it can block spring clamp 5, spring clamp 5 and spring 6 are all enclosed within spring shaft 10, and spring shaft 10 is contained in the center of top cover 3. When the water closet needs to be filled with water, the spring pressing plate 5 is blocked by the clamping plate 4, the spring 6 is compressed, and the water is pressurized to realize water filling. Need to move away spring pressing plate 5 when having waste water to flow into this water tank, make its spring stretch, the water recovery normal pressure of water tank, waste water flows into this water tank by the washbasin of high position. The overflow port 7 is located at the upper end of the side of the casing, the position is lower than the washbasin and is connected with the sewer. The water outlet valve 8 is a one-way valve that can only flow out and not flow in. It is connected to the water outlet of the water tank, and the other end is connected to the water closet. The water inlet of the storage tank. The blowdown outlet valve 9 is a ball valve that links to each other with the blowdown outlet, and is located at the lowermost end of the casing.

Claims (2)

1, a kind of storage tank that can recycle waste water, comprise casing, top cover, wherein said casing comprises water inlet, delivery port, sewage draining exit, overfall, it is characterized in that described water inlet is connected to the individual event valve that advances only to go out, and links to each other with the outfall of wash basin; Described delivery port is connected to the individual event valve that goes out only to advance; Described sewage draining exit is provided with its lower end, casing side, and is connected to ball valve, and described overfall is provided with its upper end, casing side, links to each other with sewer.
