Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a green construction water recycling system. Background Art

[0002] Green construction refers to construction activities that, under the premise of ensuring basic requirements such as quality and safety, maximize resource conservation and reduce negative impacts on the environment through scientific management and technological progress, thereby achieving energy conservation, land conservation, water conservation, material conservation and environmental protection.

[0003] The existing construction water recycling system usually transports rainwater and wastewater to the filter pool for filtration, and then directly transports it to various pipes for water replenishment through water pumps. Due to the limited purification capacity of rainwater and wastewater, it often needs to be mixed with tap water to ensure sufficient water supply. However, a large amount of mixed tap water does not save water resources. Therefore, we proposed a green construction water recycling system to solve the above problems. Utility Model Content

By connecting the second type of water source supplementary pipe to the first float valve, when the first type of water source and recycled water in the fire water tank or construction water tank are insufficient, the water level drops and the first float valve is opened to release the second type of water source. When the water level rises to a suitable position, the first float valve automatically closes. In this process, the second type of water source only serves as a backup water source, which saves water while ensuring sufficient water supply.

A water delivery pipe 13 and a connecting pipe 33 are provided between the fire water tank 2 and the construction water tank 3. Both ends of the water delivery pipe 13 and the connecting pipe 33 are respectively connected to the bottom of the fire water tank 2 and the construction water tank 3. The upper ends of the fire water tank 2 and the construction water tank 3 are provided with a first type of water source replenishment pipe 14 and a second type of water source replenishment pipe 15.

Each second type of water source replenishment pipe 15 is provided with a first float valve 16, and each first float valve 16 is respectively installed inside the fire water tank 2 and the construction water tank 3;

[0031] A connecting valve is installed in the connecting pipe 33, and a connecting valve is also installed in the water pipe 24 between the fire pipe 20 and the spray pipe 19. The first type of water source replenishment pipe 14, the second type of water source replenishment pipe 15, the water pipe 13 and the outer side of the bifurcated pipe 11 are all connected with a plurality of maintenance valves 34. The maintenance valves 34 are used to interrupt the water supply of each pipe to prevent the waste of water resources when the pipe is damaged, and at the same time facilitate workers to repair the pipe;

[0032] An observation port 32 is provided at the upper end of the fire water tank 2 and the construction water tank 3. The size of the observation port 32 is 500*500mm. Each observation port 32 is located at the upper end of the corresponding first float valve 16. A tank cover is hinged at the upper end of the observation port 32. A cleaning pipe 17, a construction pipe 18, a spray pipe 19 and a fire pipe 20 are fixedly installed side by side in the booster pump room 4.

The controllers on the cleaning pipe 17, the construction pipe 18 and the fire pipe 20 are all electrically connected to a remote control pressure gauge 22.

[0033] The remote-controlled pressure gauge 22 is used to monitor the water pressure in the cleaning pipe 17, the construction pipe 18, and the fire-fighting pipe 20. When the water pressure in each pipe decreases, the remote-controlled pressure gauge 22 opens the corresponding water pump 21 through the controller to replenish water. The spray pipe 19 is provided with a dust monitoring device 23 electrically connected to the controller. The dust monitoring device 23 is used to detect the degree of pollution in the air, so as to open the water pump 21 on the spray pipe 19 through the corresponding controller to work. The function of the cleaning pipe 17 is to transport recycled water to various cleaning points for washing roads, maintaining concrete and washing construction vehicles. The function of the construction pipe 18 is to transport recycled water to the construction water points on each floor of each building. The function of the fire-fighting pipe 20 is to transport recycled water to the fire hydrants on each floor of each building and the fire-fighting pipe 20. The spray pipe 19 is connected to the construction enclosure spray system.

[0034] The specific implementation process is as follows:

[0035] When rainwater and construction wastewater are recycled, the rainwater flows into the sedimentation tank 6 in the rainwater collection tank 1 through the water inlet 9. The solid particulate matter in the rainwater settles in the gaps formed by the coarse stones in the rectangular iron frame 30 due to its own gravity. The rainwater deposited in the sedimentation tank 6 enters the coarse filtration tank 7 through the water inlet 12 on the right partition 5, and then the pollutants are removed by the adsorption of the activated carbon placed inside the rectangular iron frame 30, thereby purifying the rainwater. The purified rainwater enters the fine filtration tank 8 through the water inlet 12 on the left partition 5, and is further filtered through the 8D filter screen in the rectangular iron frame 30 to form recycled water.

[0036] The recycled water enters the bifurcated pipe 11 through the outlet 10 on the outer wall of the rainwater and wastewater collection pool 1, and flows into the connected fire water tank 2 and construction water tank 3 through the bifurcated pipe 11 for storage. At this time, each connecting valve is in a closed state, and each maintenance valve 34 is in an open state. The first type of water source replenishment pipe 14 connected to the upper end of the fire water tank 2 and the construction water tank 3 can replenish mountain water and groundwater for them, and the second type of water source replenishment pipe 15 connected to the upper end of the fire water tank 2 and the construction water tank 3 can replenish tap water for them. When the recycled water and the first type of water source are insufficient, the first float valve 16 connected to the second type of water source replenishment pipe 15 is connected with the water level. The water level in the water tank 3 is lowered, thereby opening the first float valve 16, and delivering tap water through the second water source supplementary pipe 15, so as to keep the water level in each water tank sufficient at all times and avoid sudden interruption of the water source. The water delivery pipe 13 is connected with the cleaning pipe 17, the construction pipe 18, the spray pipe 19 and the fire fighting pipe 20 in the booster pump room 4. Since the connecting valves are in the closed state at this time, the cleaning pipe 17, the construction pipe 18 and the spray pipe 19 can only use the water source in the construction water tank 3, and the fire fighting pipe 20 can only use the water source in the fire fighting water tank 2, so that the fire fighting pipe 20 and other pipes can be operated independently;

[0037] When the water consumption in the fire water tank 2 increases and the water supply is insufficient, the construction water tank 3 can be connected to the fire water tank 2 by opening each connecting valve, so as to increase the water supply to the fire pipe 20 and ensure that the water supply to the fire pipe 20 is sufficient. When the remote control pressure gauge 22 connected to the cleaning pipe 17, the construction pipe 18 and the fire pipe 20 detects that the water pressure of each pipe decreases, the controller starts the corresponding water pump 21 of each pipe to work, and the water stored in the construction water tank 3 is transported to the corresponding pipe through the water pipe 13 for replenishment. When the dust monitoring device 23 detects that the air pollution level is high, the controller starts the water pump 21 connected to the spray pipe 19 to transport the water to the construction fence spray system for dust reduction treatment. The recycled water after use flows back into the rainwater and wastewater collection pool 1 through the ditch on the ground for filtration and circulation. In this process, the second type of water source is only used as a backup water source, which saves water while ensuring sufficient water supply.

[0038] Example 2

[0039] Example 2 is basically the same as Example 1, further: Figure 2 As shown, the construction fence spray system includes a water pipeline 24 and a booster main unit 25. The rated power of the booster main unit 25 at a rated voltage of 380V is 3kW, and a booster main unit 25 is added for every 200 meters of the water pipeline 24. The water pipeline 24 is arranged in a rectangular shape to surround the construction site. The spray pipeline 19 between the booster pump room 4 and the booster main unit 25 is connected to a stop valve 26 and a water filter 27. The water filter 27 further filters and recovers fine impurities in the water to prevent impurities from clogging the nozzle 29. The booster main unit 25 is provided with a second float valve 28, which is connected to the spray pipeline 19. The second float valve 28 is connected to the spray pipeline 19. The valve 28 automatically cuts off the water through the liquid level in the booster main unit 25, thereby protecting the booster main unit 25. A number of nozzles 29 are evenly connected to the outside of the water supply pipe 24. The nozzle 29 close to the front end of the booster main unit 25 adopts a stainless steel high-pressure direct spray type internal nozzle 29, and the rear end adopts a stainless steel low-pressure direct spray type internal nozzle 29. The spray distance is 1.5m and the installation spacing is 1m. The construction fence spray system can also be used on construction tower cranes. The principle is roughly the same. The difference is that the booster main unit 25 and the water filter 27 are installed at the rear end of the driver's cab, and the water supply pipe 24 is installed on the outside of the crane arm, so as to cool down or reduce dust on the tower crane boom.
