Description

Roof rainwater recovery purification and classification reuse device

technical field

The utility model relates to a device for recovering, purifying, classifying and reusing rainwater on a roof, and belongs to the technical field of rainwater purification and recovery equipment.

Background technique

There are two major problems in my country's water resources: one is the shortage of water resources, and the other is serious water pollution. According to data, my country is a country with severe drought and water shortage. Per capita fresh water resources are only 1/4 of the world's average level, ranking 110th in the world. It is one of the countries with the poorest per capita water resources in the world. In order to alleviate the severe water situation, actively develop water-saving industrial and agricultural technologies, Vigorously promote the application of water-saving appliances, discover and eliminate water leakage, including leakage in water-using appliances and water delivery pipe networks. Countries around the world are now turning to the development of non-traditional water resources. Non-traditional water resources include: rainwater, recycled sewage, seawater, and aerial water. According to reports, at present, the reuse rate of industrial water in my country is only 60%, and there is almost no urban wastewater utilization. Moreover, the recovery and purification equipment in developed countries is expensive, which is not suitable for personal and family use, especially in a large number of rural areas in my country.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings, but not as any limitation to the utility model.

The utility model is constructed according to the following method. The principle is: when it rains, the rainwater is collected in the open-air layer, and the rainwater passes through the S-shaped pipe and the filter layer to filter out most of the impurities, and then flows into the sedimentation tank, passes through the sedimentation, and is filtered A small amount of impurities that have not been filtered out in the sedimentation tank will settle at the bottom of the tank. When the water level exceeds the drain pipe inlet of the sedimentation tank, the clean upper layer water will flow into the reservoir, and the sediment at the bottom of the sedimentation tank can pass through the bottom of the sedimentation tank. The water with poor water quality can also be reused, such as flushing toilets. In the reservoir, when the water level is higher than the third-level water outlet, the water can be used for daily use. The water quality of this part of the water is better, and can be used for washing hands, face, feet, mopping the floor, etc. If the family is short of water and the water is cut off, the water released from the secondary water outlet of the reservoir can be used, because the water quality of the reservoir is better than that of the sedimentation tank, and the water can be taken according to the actual situation. If the equipment is used for a long time, it is necessary to replace the filter layer, clean the open layer, and clean the sedimentation tank and reservoir on time (open the switch of the first and second water outlets, and the sediment will flow out with the water).

The device for recovering, purifying, classifying and reusing rainwater on the roof constructed according to the above method includes a roof 1, in which a reservoir 2, a sedimentation tank 3, a filter layer 4 and an open-air layer 5 are respectively arranged from bottom to top. The drain hole 5.1 on the open-air layer 5 is connected to the water inlet of the pipeline 4.2 in the filter layer 4, the water outlet of the pipeline 4.2 in the filter layer 4 is connected to the sedimentation tank 3, and the drainage pipe 3.1 of the sedimentation tank 3 is connected to the water storage tank 2 Pass. Wherein at the bottom of the sedimentation tank 3, a drainage pipe 3.1 is provided, and the drainage pipe 3.1 is 5cm smaller than the height b of the sedimentation tank 3 itself, and a first-level water intake 8 is provided at the bottom of the sedimentation tank 3 on one side; An S-shaped pipeline 4.2 is provided on the top, a filter device 9 is provided in the pipeline 4.2, and a sealing cover 4.1 is provided on the pipeline at the filter device 9; A drain hole 5.1 is provided at one corner of the drain hole, and the drain hole 5.1 can communicate with the beginning of the pipe 5.2 in the filter layer 4, and a filter layer seal/replacement cover 10 is provided in the middle of the open-air layer 5 and higher than the bottom of the open-air layer 5, and the filter layer is sealed The replacement cover 10 is arranged directly above the filtering device 9, and a drain tank 11 is provided on one side of the open-air layer 5 close to the bottom position.

Specific production steps

Step 1, making the water storage tank, because in rural bungalows, the top of the house can be used as the bottom of the water storage tank, and then build high along the walls of the house, and use the house as a water storage tank to store rainwater. Draw two tertiary water outlets on one of the pool walls 20 cm away from the bottom of the pool, and then draw a second-level water outlet with the same diameter on a pool wall with the same height as the bottom of the pool. However, in the long-term process of water storage, in order to prevent roof leakage and water seepage, fine sand and mineral pellets are the best choice for SBS coiled materials, and hot-melt construction is generally used; if cement mortar is to be added, self- Adhesive waterproof membrane is constructed by wet laying method. At the same time, the bearing capacity of the roof should also be considered, and the beams and reinforced concrete of the roof can be thickened to ensure the reliability of its bearing.

Step 2, making the sedimentation tank, continue to make a pond with the same size as the reservoir on the reservoir, the height of the sedimentation tank is 25cm, and it is built with reinforced concrete; and there are 2 drainage pipes in the sedimentation tank, and the drainage pipes adopt the existing Some pc pipes, and the height should be about 5cm lower than the height of the sedimentation tank, and there are two primary water outlets on one side of the sedimentation tank close to the bottom of the tank.

Step 3. Fabrication of the filter layer. There is a support frame at the bottom of the filter layer. The support frame is composed of a conventional steel frame or wood. An S-shaped square plastic pipe is installed on the support frame and a filter device is installed in the pipe. The water inlet of the pipe It has an inclination angle of about 5 degrees with the water outlet. The filter device is composed of quartz sand and small stones. It is installed in the middle of the horizontal pipe of the S-shaped pipe. A sealing cover is installed above the filter layer to facilitate the replacement of the filter layer.

Step 4. Make the open-air layer. The open-air layer is the part that collects rainwater. It is built above the filter device. The structure is the same as the roof. The difference is that a water outlet is left to connect with the water inlet of the S-shaped pipe. Two gutters are respectively drawn on the two pairs of pool walls of the open-air layer. When the reservoir is full, the excess rainwater is discharged through the outlet of the open-air layer to prevent rainwater from overflowing. A filter is installed in the middle of the open-air layer. Layer sealing/replacement cover, the filter layer sealing/replacement cover is located directly above the filter unit.
