Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an automatic end-of-line recycling system for construction and production water within a building. Background Technology

[0002] In the construction industry, especially in the construction and operation phases of high-rise buildings, water conservation and recycling are crucial for achieving green construction and sustainable development.

[0003] During the construction phase, existing technologies primarily focus on macroscopic rainwater harvesting from the ground. However, these systems require large land areas, necessitate the construction of large underground or semi-underground water tanks, and rely on pumps for pressurization and distribution, resulting in high energy consumption. Alternatively, they rely on surface-mounted reservoirs and centralized filtration equipment rooms, using pumps and complex filtration systems to supply water for construction and dust suppression.

[0004] This system neglects end-point leakage, and water waste still exists: Existing construction-phase water recycling systems mainly focus on collecting rainwater runoff from the ground and centralized industrial wastewater discharge, but lack effective source collection methods for continuous dripping and seepage inside construction floors, especially at each floor's water distribution point valves due to improper closure, damage, or worker misuse. This "slow and steady" water flow accumulates to a considerable amount, representing a hidden waste in construction costs. Moreover, the system is complex and costly, unsuitable for temporary construction: Existing systems, whether in operation or construction phases, often include complex filtration equipment, multiple water tanks, and power pumps. The system construction cost is high and the cycle is long, which is incompatible with the temporary and short-term characteristics of building construction, resulting in poor economy and convenience. Utility Model Content

[0005] The purpose of this utility model is to propose an automatic end-of-line recycling system for construction and production water within a building, which automatically collects dripping wastewater to a ground floor water tank for reuse, thus eliminating the damage and safety hazards of water accumulation on the lower floor decoration.

[0006] To achieve the above objectives, the technical solution of this utility model is: an automatic end-of-line recycling system for construction and production water within a building, wherein a water storage tank is installed below the valve of the water distribution point on each floor of the building, an overflow port is installed on the upper side wall of the water storage tank, the overflow port is connected to a recycling branch pipe, the other end of the recycling branch pipe is connected to a recycling main pipe, the recycling main pipe runs vertically through multiple floors of the building, and a water storage tank is installed at the bottom of the building, which is connected to the bottom end of the recycling main pipe.

[0007] Furthermore, the height of the overflow outlet is lower than the opening of the water storage tank, and the height of the connection point between the recovery branch pipe and the overflow outlet is higher than the height of the connection point between the recovery branch pipe and the recovery main pipe.

[0008] Furthermore, the connection point between the recovery branch pipe and the overflow port is 10-20mm higher than the connection point between the recovery branch pipe and the recovery main pipe.

[0009] Furthermore, the water storage tank is equipped with baffles for settling impurities.

[0010] Furthermore, the bottom of the main recycling pipeline is equipped with a removable cleaning port.

[0011] Furthermore, the main recycling pipeline and the branch recycling pipeline are made of metal or plastic.

[0012] Furthermore, the water storage tank is a modified industrial container.

[0013] The beneficial effects of this utility model are: by installing water storage tanks and recycling pipes on each floor, this utility model realizes the automatic collection of water resources that are wasted in the "slow and steady" manner during construction to the ground floor water tank for reuse, directly reducing the cost of construction water. The main components of the system can be made from recycled materials or assembled from standard parts, resulting in low investment costs and reusable equipment.

[0014] This completely eliminated the problem of floor leakage caused by water accumulation, effectively protecting the completed decoration and renovation work on the lower floors (such as ceilings, walls, and electrical facilities), and eliminating the risk of quality defects and rework. At the same time, it kept the floor dry, reducing the safety hazards of workers slipping and falling, and creating a safer and cleaner working environment for the construction site.

[0015] With its outstanding green and environmentally friendly features, the collected wastewater can be directly used for non-drinking construction processes such as water spraying for dust suppression, vehicle washing, and concrete curing, which greatly improves the water resource recycling rate, meets the requirements of green construction, and has significant social benefits.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] An automated end-of-pipe recycling system for construction and production water within a building, such as Figure 1 As shown, a water storage tank 2 is installed below the water distribution valve 1 on each floor of the building. An overflow port 21 is installed on the upper side wall of the water storage tank 2. The overflow port 21 is connected to the recycling branch pipe 4. The other end of each recycling branch pipe 4 is connected to the recycling main pipe 3, so that when the water level in the water storage tank 2 reaches the overflow port 21, the wastewater can flow into the recycling main pipe 3 through the recycling branch pipe 4. A water storage tank 5 is installed at the bottom of the building and is connected to the bottom end of the recycling main pipe 3 to collect and store wastewater from each floor. The recycling main pipe 3 vertically runs through multiple floors of the building.

[0020] It should be noted that the manufacturing and installation steps of the water storage tank 2 involve using a discarded industrial iron drum with a volume of approximately 100 liters. This drum is horizontally cut in half from the middle to create two water storage tanks 2, thus achieving waste recycling. One of these water storage tanks 2 is placed directly below the pre-installed construction water distribution valve 1 on each floor to directly collect any leaks from the valve and any small amounts of residual wastewater after worker use. A DN50 circular hole is made on the side wall of the water storage tank 2, 400mm from the bottom, as an overflow outlet 21.

[0021] This embodiment is further configured such as... Figure 2 As shown, the height of the overflow outlet 21 is lower than the opening of the water storage tank 2, and the height of the overflow outlet 21 is slightly higher than the height of the connection point between the recycling branch pipe 4 and the recycling main pipe 3, so that the recycling branch pipe 4 forms a slope that facilitates the gravity flow of wastewater.

[0022] This embodiment is further configured such that a baffle 51 for settling impurities is provided inside the water storage tank 5. For example... Figure 4 As shown, a removable cleaning port 31 is provided at the bottom of the main recycling pipe 3. The main recycling pipe 3 and the recycling branch pipe 4 can be made of metal pipe or plastic pipe, and welded steel pipe is preferred in this embodiment.

[0023] It should be noted that the pipeline system installation steps are as follows: The main recovery pipeline 3 uses a DN50 welded steel pipe, running vertically from the ground floor to the top floor of the building, and is fixed in the building's core tube or pipe shaft, or other areas that do not affect construction. Before installation, a hole for penetrating the floor slab must be reserved according to the drawings. The diameter of the hole is two sizes larger than the pipe diameter, and after installation, it must be tightly sealed with fine aggregate concrete. The recovery branch pipe 4 also uses a DN50 welded steel pipe. One end is welded to the overflow port 21 of the water storage tank 2, and the other end is connected to the main recovery pipeline 3. During installation, it must be ensured that the branch pipe has a significant slope, that is, the connection point between the branch pipe and the overflow port 21 is about 10-20mm higher than its connection point with the main pipeline 3, so that the wastewater can flow into the main pipeline automatically and smoothly by gravity. A DN50 removable cleanout port 31 is installed at the bottom of the main recovery pipeline 3 on the first floor to facilitate future pipeline maintenance and dredging.

[0024] It should be noted that a 3m³ water storage tank should be installed on the outer side of the first floor of the building, in a location convenient for water access and management. Figure 3 As shown, the water storage tank is welded from 3mm thick steel plates, with internal dimensions of 2m long × 1.5m wide × 1m high. To enhance the sedimentation effect, baffles 51 are welded inside the tank.

[0025] The end of the main recovery pipe 3 extends from the top of the water storage tank 5, injecting the collected wastewater into the tank.

[0026] It should be noted that a water storage tank 2 is arranged below the construction water distribution point 1 on each floor of the building to collect dripping and residual construction wastewater. When the water level in a single water storage tank 2 reaches the height of its overflow port 21, the wastewater automatically overflows into the main recycling pipe 3 through the recycling branch pipe 4. The wastewater flows by gravity through the main recycling pipe 3 and finally flows into the water storage tank 5 at the bottom floor for storage. The wastewater collected in the water storage tank 5 is used for non-potable construction purposes, realizing the recycling of water resources.

[0027] The system operates fully automatically without external force: It collects dripping water from the floor water distribution valve 1 and wastewater from workers' washing tools, which is then dripped or poured directly into the water storage tank 2 below it.

[0028] Sedimentation and Overflow: Storage tank 2 initially acts as a primary sedimentation tank, where heavy objects such as silt in the wastewater settle at the bottom. When the water level in the tank reaches the overflow port 21, which is 400mm high, the relatively clear upper layer of wastewater automatically overflows into the main recycling pipe 3 through the recycling branch pipe 4. Transportation and Storage: Wastewater from each floor flows into the main pipe through the branch pipes and then flows downwards to the ground floor of the building by gravity, eventually all flowing into the storage tank 5. Baffles 51 in the tank settle the water flow. Water from the main recycling pipe first enters the first zone. Because the inlet is above the water surface, the water flow has initial kinetic energy. However, when the water enters the larger first zone, the flow velocity drops sharply, which is the first key condition for sedimentation. Next, the water flow needs to overturn the baffle to enter the next zone. This "overturning" action further consumes and disperses the energy of the water flow, making it very slow and calm in the next zone, preventing the flow of impurities and causing them to settle in the first zone. Reuse: A dedicated person is assigned to manage the construction site. When it is necessary to carry out operations such as watering to reduce dust, washing vehicles, or curing concrete, a submersible pump or directly draws recycled water from the water storage tank 5.
