technical field

The invention relates to the field of rainwater utilization devices, in particular to a fully automatic rainwater comprehensive utilization combined system.

Background technique

my country's rainwater resources are very rich, with an annual rainfall of 6.19 trillion m3, which is one of the important freshwater resources available to our country. For a long time, most cities in my country have mainly used surface water such as rivers and lakes, groundwater, and transferred water as resources, while natural rainwater has been rarely used or even ignored.

As a precious resource, rainwater plays a very important role in the urban circulation system and watershed water environment system. Due to the increase of urban and rural hardening areas, the increase of rainwater loss and the destruction of the balance of the water circulation system have caused a series of environmental and ecological problems. The comprehensive utilization of rainwater can alleviate the shortage of water resources, reduce the runoff of rainwater on urban and rural streets and roads, and reduce drainage pressure.

Therefore, a rainwater comprehensive utilization system is needed to deal with the rainwater. However, some traditional and recent devices are electronically controlled, which consumes a lot of energy and is picky about the installation site. Therefore, there is a more precise need for a processing device that consumes less energy and can be installed flexibly.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

Embodiments of the present invention are shown in Fig. 1, and the present invention comprises box body 14, is provided with water storage tank 13, clean water tank 12 and is arranged on the filtering device 7 between water storage tank 13 and clean water tank 12 in the box body 14, and water storage tank 13 tops A water storage tank inspection hole 2 is provided, and a rainwater pipe 1 is arranged on one side of the water storage tank inspection hole 2, and a rainwater overflow pipe 4 is arranged on the other side. Going out, the bottom mounting groove is provided with a rainwater filter 3, the bottom of the rainwater filter 3 is connected with a water inlet pipe 15, a side of the bottom of the water storage tank 13 is also provided with a mud pump 16, and the bottom of the water storage tank 13 is provided with a slope. The filter device 7 is gradually lowered to the sludge discharge pump 16, so that the sludge is concentrated near the sludge discharge pump under the action of gravity for smooth sludge discharge; the top of the clean water tank 12 is provided with a clean water tank inspection hole 8, and the bottom is provided with a water supply pump 10 One side of the clean water tank 12 is also provided with a clear water overflow pipe 9; the top of the filtering device 7 is provided with a brick inspection hole 6; When the device composed of clean water tank 12 and filtering device 7 is used in parallel, the clean water tank 12 in each device can be connected by the clean water tank connecting pipe 11, and the clean water tank connecting pipe 11 is provided with a valve, so that it can be used in the case of emergencies. Efficient maintenance without excessive loss of usable water.

The present invention is a device that integrates a water storage tank, a filtering device and a fresh water tank. The material of the device can be made of three different materials: PE, stainless steel and tempered glass, so as to meet the needs of different projects. When buried, a 20cm-thick coarse sand layer is buried around the device to prevent damage to the device during landfilling.

As shown in Figure 2, the rainwater enters the inspection hole 2 of the water storage tank from the rainwater pipe 1 and is initially filtered by the rainwater filter 3 to filter out large impurities. In the water tank 13, the rainwater in the water storage tank enters into the clean water tank 12 after being filtered by the filter device 7 to reach the standard. The bottom of the water storage tank is provided with a slope, so that the sludge is automatically deposited to the lowest part of the water storage tank under the action of gravity, so that the sludge discharge pump 16 can discharge the sludge smoothly. The water in the fresh water tank is extracted and utilized by the water supply pump 10 . After the water in the clear water tank is full, it overflows by the clear water overflow pipe 9, and the rainwater filtered and collected when the rainfall is too large overflows by the rainwater overflow pipe 4. The coarse sand layer 5 is buried around the device in the ground, and a brick inspection hole 6 is arranged on the top of the filter device.

As shown in Figure 2 and 3, the filter device is made of filter plates composed of four different filter media, and different filter media are selected according to different water quality requirements. When installing, put the four kinds of filter plates in an open filter box to ensure the sealing between the filter box and the filter plate, and also set a sealing device on the filter box. A card slot for the filter box is arranged on the box body where the filter device is placed, so that the filter box can be installed in the whole device in a sealed manner.

The pipe connections in this device are welded with the device to ensure the sealing and stability between them. Due to its small size, this device can be used in parallel in different projects. When used in parallel, use the connecting pipe of the clean water tank to connect all The fresh water tank is connected together, and a pump is used for water supply, which can greatly reduce energy consumption. The device of the present invention can be used and installed flexibly under different conditions because it can be used in parallel, without limitation. The device can also be installed in pieces or in sections in the project, which can achieve the effect of being ready-to-down and ready-to-use. Because the device of the present invention is buried in the ground, the depth of the ground is different, and the height of the device is insufficient. In some cases, brick inspection holes can be supplemented in the inspection vacancy.

The device of the present invention is a fully automatic operation device, so the device needs to be cleaned and discharged regularly. For the filter device with complicated cleaning, the filter box is set as one for use and one for standby, which can be replaced directly during cleaning without affecting the operation of the device.

To sum up, the device of the present invention provides a fully automatic rainwater comprehensive utilization combined device, which can realize fully automatic collection, storage and treatment of rainwater. Due to its small size, high flexibility, and compact device, different installation requirements can be made according to different building and residential water utilization plans, and there is no deliberate requirement in terms of land use. In addition, compared with the existing water treatment devices, the device of the present invention has low cost, low energy consumption, low land requirements, flexible installation, and does not require other electric energy to control the operation of the device. Therefore, the device of the present invention is a fully automatic rainwater treatment device. Comprehensive utilization of combined devices is more economical and simple.

The above disclosure is only a preferred embodiment of the present invention, which certainly cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
