Description

Technical Field

[0001] This invention belongs to the field of wastewater separation technology, specifically relating to a precise control system for wastewater separation. Background Technology

[0002] In environments such as mining and field laboratories, clean water resources are scarce. Indiscriminate discharge of wastewater can easily cause ecological pollution. Due to the preciousness of water resources, lightly polluted water can be recycled and reused, while heavily polluted wastewater can be temporarily stored or transferred. In field settings, diversion pipelines are affected by viscous impurities from mine tailings and residual chemicals from field laboratories. During long-term wastewater transport, impurities easily adhere to the inner walls of the pipelines, narrowing the flow cross-section and affecting the detection data of water quality sensors, thus impacting the ability to distinguish between clean and wastewater. Clean water may enter the wastewater collection unit, resulting in waste, or the flowing clean water may wash away impurities from the inner walls of the pipeline, contaminating the clean water and hindering its reuse. Therefore, how to achieve efficient clean and wastewater separation in field environments and reduce the waste of clean water resources is a problem that those skilled in the art need to solve. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a precise control system for separating clean and polluted water, which can realize automated control of water diversion, storage, and flushing without the need for additional clean water supply devices. This maximizes the utilization of clean water resources in the wild, avoids pipe blockage or clean water pollution caused by dirt, and ensures long-term stable operation of the system.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] A precise control system for separating clean and polluted water is provided for controlling the flow direction of water in a separation pipeline. The separation pipeline includes a main pipeline, a clean water pipeline, and a sewage pipeline. The inlets of the clean water pipeline and the sewage pipeline are respectively connected to the outlet side of the main pipeline. The outlet of the clean water pipeline is connected to a clean water collection unit, and the outlet of the sewage pipeline is connected to a sewage collection unit. The control system is electrically connected to a power supply device, which includes a battery and a solar panel. A pipeline flushing unit is also provided on the separation pipeline. The control system includes a controller, an inlet valve, a sewage valve, a clean water valve, and a branch valve of the pipeline flushing unit. The inlet valve is located on the inlet side of the main pipeline, the sewage valve is located on the sewage pipeline, and the clean water valve is located on the clean water pipeline. The control terminal of the controller is connected to the controlled terminals of the inlet valve, the sewage valve, the clean water valve, and the branch valve.

[0006] The pipeline flushing unit includes a water storage tank, which is connected to a clean water pipeline via a branch pipe. The clean water valve includes a first valve and a second valve. The branch pipe is located between the first valve and the second valve, and the branch pipe valve is located on the branch pipe.

[0007] The water storage tank includes a support frame and a pressure cylinder. The pressure cylinder is mounted on the support frame and supported by the support frame. The branch pipe is connected to the pressure cylinder.

[0008] The pressure cylinder is a rubber cylinder. The support frame includes an upper support, a lower support, and a telescopic sleeve. The upper and lower ends of the telescopic sleeve are connected to the upper support and the lower support, respectively. A telescopic cylinder is provided between the upper support and the lower support. The pressure cylinder is located inside the cavity of the telescopic sleeve. The upper end of the pressure cylinder is connected to the upper support, and the lower end is connected to the lower support.

[0009] The pressure cylinder is connected to the main pipeline via a flushing pipe, and a flushing valve is installed on the flushing pipe. The controlled end of the flushing valve is connected to the control end of the controller.

[0010] A sensor module is installed on the main pipeline. The sensor module is located between the inlet and outlet sides of the main pipeline. The sensor module is connected to the controller. The sensor module includes a flow meter, a conductivity meter, an ORP meter, a pH meter, and an ammonia nitrogen sensor.

[0011] A control method for a precise control system for separating clean and polluted water flows includes the following steps:

[0012] S1. Open the inlet valve, and clean water flows into the inlet side of the main pipeline. The controller opens the first valve and the branch valve, and closes the sewage valve, the second valve and the flushing valve. The clean water flows into the pressure cylinder for storage. After the pressure cylinder has finished storing, close the branch valve and open the second valve. The clean water flows from the clean water pipeline to the clean water collection unit for collection.

[0013] S2. Sewage flows into the inlet side of the main pipeline. Close the first valve and open the sewage valve. The sewage flows from the sewage pipeline to the sewage collection unit for collection.

[0014] S3. After the sewage has flowed in the main pipe and sewage pipe for a set time, close the inlet valve and keep the sewage valve open. Then, alternately open and close the flush valve and the branch valve.

[0015] S4. When clean water flows into the main pipeline again, keep the sewage valve open. After the clean water flows in the main pipeline for a set time, repeat step S1.

[0016] In step S3, when the flushing valve and branch valve are opened and closed, the telescopic cylinder reciprocates to drive the pressure cylinder to lengthen and shorten.

[0017] The beneficial effects of this invention are:

[0018] This invention employs a pipe flushing unit installed in the diversion pipe. When clean water flows into the inlet side of the diversion pipe, the controller closes the sewage valve, controls the clean water to replenish the pipe flushing unit, and controls the clean water to flow to the clean water collection unit. When sewage flows into the inlet side of the diversion pipe, the controller closes the clean water valve and opens the sewage valve, allowing the sewage to flow through the sewage pipe to the sewage collection unit, thus achieving separation of clean and sewage.

[0019] Clean water is stored in the pipe flushing unit, which can be used to flush back the water to the clean water pipe and the main pipe, reducing impurities attached to the inner walls of each pipe. The flushed wastewater flows into the wastewater collection unit through the wastewater pipe, realizing automated control of diversion, water storage and flushing. No additional clean water supply device is required, maximizing the use of outdoor clean water resources, avoiding pipe blockage or clean water pollution caused by dirt, and ensuring long-term stable operation of the system.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] Specific implementation examples Figure 1As shown, this invention relates to a precise control system for separating clean water and sewage, used for controlling the flow direction of water in a separation pipe 1. The control system is electrically connected to a power supply device, which includes a battery and a solar panel. The battery is a lithium battery, which stores electrical energy. The solar panel replenishes the lithium battery with electrical energy. The lithium battery powers the control system. It is suitable for outdoor scenarios without a stable power grid. The separation pipe 1 includes a main pipe 2, a clean water pipe 3, and a sewage pipe 4. The inlets of the clean water pipe 3 and the sewage pipe 4 are connected to the outlet of the main pipe 2, respectively. The outlet of the clean water pipe 3 is connected to a clean water collection unit, and the outlet of the sewage pipe 4 is connected to a sewage collection unit.

[0027] A pipe flushing unit is also installed on the diversion pipe 1. The control system includes a controller 5, an inlet valve 6, a sewage valve 7, a clean water valve 8, and a branch valve 9 for the pipe flushing unit. The inlet valve 6 is located on the inlet side of the main pipe 2, the sewage valve 7 is located on the sewage pipe 4, and the clean water valve 8 is located on the clean water pipe 3. The control terminal of the controller 5 is connected to the controlled terminals of the inlet valve 6, sewage valve 7, clean water valve 8, and branch valve 9, respectively. When clean water flows into the inlet side of the diversion pipe 1, the controller 5 closes the sewage valve 7, controls the clean water to replenish the pipe flushing unit, and controls the clean water to flow to the clean water collection unit. When sewage flows into the inlet side of the diversion pipe 1, the controller 5 closes the clean water valve 8 and opens the sewage valve 7, allowing the sewage to flow through the sewage pipe 4 to the sewage collection unit, thus achieving separation of clean and sewage.

[0028] Clean water is stored in the pipe flushing unit. The clean water in the pipe flushing unit can be used to drain water into the clean water pipe 3 and the main pipe 2 to achieve reverse flushing, reducing the impurities attached to the inner walls of each pipe. The flushed wastewater flows into the wastewater collection unit through the wastewater pipe 4, realizing the automatic control of diversion, water storage and flushing. There is no need to set up an additional clean water supply device, maximizing the use of outdoor clean water resources, avoiding pipe blockage or clean water pollution caused by dirt, and ensuring the long-term stable operation of the system.

[0029] The pipeline flushing unit includes a water storage tank 10, which is connected to the clean water pipeline 3 via a branch pipe 11. The clean water valve 8 includes a first valve 801 and a second valve 802. The branch pipe 11 is located between the first valve 801 and the second valve 802, and the branch valve 9 is located on the branch pipe 11. Closing the second valve 802 and the sewage valve 7, and opening the first valve 801 and the branch valve 9, allows clean water to be replenished into the water storage tank. Opening the first valve 801 and the second valve 802, and closing the branch valve 9 and the sewage valve 7, allows clean water to flow to the clean water collection unit, enabling the collection of clean water and precise control of the flow of clean water into the storage channel. The first valve 801 can also block sewage in advance, maintaining a clean passage on the outlet side of the clean water pipe 3, preventing sewage from flowing through the second valve 802 and the branch valve 9 and causing impurities to adhere to the inner wall of the pipe between the first valve 801 and the second valve 802, or on the second valve 802 and the branch valve 9, thus preventing impurities from flowing to the water storage tank or clean water collection unit under the flushing action of clean water.

[0030] like Figure 3 , Figure 4 As shown, the water storage tank 10 includes a support frame 1001 and a pressure cylinder 1002. The pressure cylinder 1002 is mounted on the support frame 1001 and supported by the support frame 1001. The branch pipe 11 is connected to the pressure cylinder 1002. Specifically, the pressure cylinder 1002 is a rubber cylinder, and the support frame 1001 includes an upper support 1003, a lower support 1004, and a telescopic sleeve 1005. The lower support 1004 is fixed to the ground, and the diameter of the telescopic sleeve 1005 increases from top to bottom. The upper and lower ends of the telescopic sleeve 1005 are connected to the upper support 1003 and the lower support 1004, respectively. A telescopic cylinder 1006 is provided between the upper support 1003 and the lower support 1004. The upper and lower ends of the telescopic cylinder 1006 are connected to the upper support 1003 and the lower support 1004, respectively. The pressure cylinder 1002 is located inside the cylinder cavity of the telescopic sleeve 1005. The upper end of the pressure cylinder 1002 is connected to the upper support 1003, and the lower end is connected to the lower support 1004. The telescopic sleeve 1005 provides lateral constraint for the pressure cylinder 1002 to prevent the pressure cylinder 1002 from expanding excessively laterally.

[0031] The pressure cylinder 1002 is connected to the main pipe 2 via the flushing pipe 18. A flushing valve 12 is installed on the flushing pipe 18, and the controlled end of the flushing valve 12 is connected to the control end of the controller 5.

[0032] The rubber pressure cylinder 1002 is elastic. After the pressure cylinder 1002 is filled with clean water, more clean water is added to the pressure cylinder 1002. The pressure cylinder 1002 expands and undergoes elastic deformation, while at the same time exerting a squeezing force on the clean water inside. When it is necessary to flush the pipe, the branch valve 9 or the flushing valve 12 is opened. The pressure cylinder 1002 squeezes the clean water inside, and pressurized water flows out of the pressure cylinder 1002 into the clean water pipe 3 or the main pipe 2.

[0033] By setting up a pressure cylinder 1002, the present invention enables the water storage tank 10 to both store water and have drainage pressure, eliminating the cost of configuring a slurry pump and reducing the difficulty of system maintenance.

[0034] On the other hand, the telescopic cylinder 1006 extends and retracts, causing the telescopic sleeve 1005 to extend or shorten, and at the same time causing the pressure cylinder 1002 to extend or shorten. When the pressure cylinder 1002 extends, it generates a rebound force to squeeze the clean water and form a high-pressure water flow. When the pressure cylinder 1002 shortens from the extended state, the pressure decreases. The repeated extension and shortening forms a pulsed water flow, which improves the flushing effect on the dirt on the pipe wall. In addition, after the pressure cylinder 1002 shortens, it can also squeeze and empty the residual clean water inside the pressure cylinder 1002, assisting the discharge of the clean water stored inside to participate in the flushing and reducing water waste.

[0035] A sensor module is installed on the main pipeline 2, located between the inlet and outlet sides of the main pipeline 2. The sensor module is connected to the controller 5. The sensor module includes a flow meter 13, a conductivity meter 14, an ORP meter 15, a pH meter 16, and an ammonia nitrogen sensor 17. The flow meter 13 monitors the inlet flow rate, the conductivity meter 14 detects the ion concentration in the water, the ORP meter 15 measures the oxidation-reduction potential, the pH meter 16 detects the acidity or alkalinity of the water, and the ammonia nitrogen sensor 17 detects the ammonia nitrogen content in the water. Figure 2 As shown, the sensor module sends the detection information to the controller 5. The controller 5 integrates the information to determine whether the water flow in the main pipe 2 is clean water or sewage, thereby realizing the switching and diversion of clean and sewage and improving the accuracy of diversion.

[0036] A control method for a precise control system for separating clean and polluted water flows includes the following steps:

[0037] S1. Controller 5 opens the inlet valve 6. When controller 5 detects that clean water is flowing into the inlet side of the main pipe 2 according to the signal transmitted by the sensor module, controller 5 opens the first valve 801 and the branch valve 9, and closes the sewage valve 7, the second valve 802 and the flushing valve 12. Clean water flows into the pressure cylinder 1002 for storage. After the pressure cylinder 1002 has finished storing, the branch valve 9 is closed and the second valve 802 is opened. The clean water flows from the clean water pipe 3 to the clean water collection unit for collection. The clean water in the pressure cylinder 1002 is used to flush the pipe, and the clean water in the clean water collection unit is recycled for mining and field laboratory reuse, realizing the dual use of clean water and avoiding waste. Controller 5 obtains the amount of clean water flowing into the pressure cylinder 1002 through the flow meter 13.

[0038] When the inlet valve 6 is opened, the sewage valve 7 is also opened. Only after the sensor module detects that the water is clean can the sewage valve 7 be closed and the first valve 801 be opened for clean water storage or recycling.

[0039] S2. Sewage flows into the inlet side of the main pipe 2, the first valve 801 is closed, the sewage valve 7 is opened, and the sewage flows from the sewage pipe 4 to the sewage collection unit for collection.

[0040] S3. After the sewage flows in the main pipe 2 and sewage pipe 4 for a set time, the inlet valve 6 is closed, while the sewage valve 7 remains open. Before the flushing mode is started, the pressure cylinder 1002 is stretched by the telescopic cylinder 1006 to form high-pressure clean water. Then, the flushing mode is started, and the flushing valve 12 and the branch valve 9 are opened and closed alternately. At the same time, the telescopic cylinder 1006 reciprocates to drive the pressure cylinder 1002 to stretch and shorten, using the clean water in the pressure cylinder 1002 to flush the main pipe 2 and clean water pipe 3. The system flushes and cleans the dirt adhering to the inner wall of the pipe, the first valve 801, and the sensor module, preventing dirt from being carried into the pressure cylinder 1002 or the clean water collection unit when clean water flows in from the inlet side of the main pipe 2. The wastewater after flushing the dirt flows to the wastewater collection unit through the wastewater pipe 4. When the flushing valve 12 is opened, the water flows from the main pipe 2 to the wastewater pipe 4, flushing the main pipe 2 in a forward direction. When the branch valve 9 is opened, the water flows from the clean water pipe 3 to the wastewater pipe 4, flushing the clean water pipe 3 in a reverse direction.

[0041] S4. When clean water flows into the inlet side of the main pipe 2 again, keep the sewage valve 7 open. After the clean water flows in the main pipe 2 for a set time, repeat step S1 to ensure that the sewage in the pipe is drained and to prevent the sewage valve 7 from closing too early and causing the sewage to flow back into the main pipe 2 and contaminate the clean water.
