Abstract
Description
Technical Field
[0001] This utility model relates to the field of water recycling technology, and in particular to a bottle washing water recycling system. Background Technology
[0002] In the wine packaging process, bottle washing water is used to clean the inside and surface of glass bottles, removing dust and dirt. Because bottle washing water contains only a small amount of dust and impurities, its quality is relatively good, making it suitable for non-potable water use. However, in the current technology, many companies directly discharge bottle washing water into the sewer system during production, resulting in a significant waste of water resources.
[0003] For example, some companies use filtration devices for preliminary treatment and then recycle the water, but this requires additional investment in equipment and subsequent maintenance costs, resulting in low actual economic benefits. Furthermore, the lack of water quality monitoring measures can easily disrupt the normal operation of other processes during recycling, and may even mix wastewater from other processes into the bottle washing system, causing pollution.
[0004] Therefore, there is an urgent need for a simple and efficient bottle washing water recycling system to improve water resource utilization efficiency, reduce production costs, and meet environmental protection requirements. Utility Model Content
[0005] To address the aforementioned shortcomings, the purpose of this invention is to propose a bottle washing water recycling system that solves the problems of high cost of existing water treatment and reuse methods, and the lack of comprehensive water quality monitoring in simple filtration and reuse systems.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A bottle washing water recycling system includes a low-level water tank, a high-level water tank, a water pump, a monitoring and control unit, and an emergency pool. The low-level water tank collects bottle washing water discharged from an upstream bottle washing unit. The inlet of the water pump is connected to the bottom of the low-level water tank via a pipe, and the outlet of the water pump is connected to the top of the high-level water tank via a first pipe equipped with a first valve. The outlet of the water pump is also connected to the emergency pool via an emergency pipe equipped with an emergency valve. The bottom of the high-level water tank has an outlet, which is branched into at least three water paths via several pipes. One water path connects to the water storage tank of the packaging cooling tower, another water path connects to the water storage tank of the brewing cooling tower, and yet another water path connects to the water inlet unit for toilet flushing. Each water path is equipped with an independent valve. The first valve and the emergency valve are electrically connected to the monitoring and control unit. The monitoring and control unit is used to monitor whether the water entering the low-level water tank is normal bottle washing water. When the bottle washing water is detected to be contaminated, the monitoring and control unit controls the first valve to close and the emergency valve to open. The emergency pool is used to collect the contaminated bottle washing water in an emergency.
[0008] Preferably, the elevated water tank is connected to the brewing cooling tower via a second pipe, the packaging cooling tower is connected to the second pipe via a third pipe, and the toilet is connected to the second pipe via a fourth pipe. The connection point between the third pipe and the second pipe is point a, and the connection point between the fourth pipe and the second pipe is point b. Point a is located between point b and the elevated water tank.
[0009] The second pipeline is equipped with a second valve, which is located between point a and point b. The third pipeline is equipped with a third valve. The second valve is used to distribute the water flow in the second pipeline, and the third valve is used to distribute the water flow in the third pipeline.
[0010] Preferably, the nominal diameter of the second pipe is 80mm, the nominal diameter of the third pipe is 75mm, both the second valve and the third valve are gate valves, the opening degree of the second valve is set to 3 / 4, and the opening degree of the third valve is smaller than that of the second valve.
[0011] Preferably, the outlet of the water pump is also connected to the second pipe through a fifth pipe, and the connection point between the fifth pipe and the second pipe is point c, which is located between points a and b. The first pipe is equipped with a first valve, the fifth pipe is equipped with a fourth valve, and the second pipe is equipped with a first check valve between points a and c. The communication direction of the first check valve is from point a to the connection point c.
[0012] Preferably, the monitoring and control unit includes a pH meter.
[0013] Preferably, the monitoring and control unit includes a conductivity meter.
[0014] Preferably, the monitoring and control unit includes an online COD detection device.
[0015] Preferably, the low-level water tank is equipped with a liquid level sensor, and the monitoring and control unit is electrically connected to the liquid level sensor and the water pump.
[0016] Preferably, the first pipeline is equipped with a second one-way valve, and the connection direction of the second one-way valve is from the low-level water tank to the high-level water tank.
[0017] Preferably, the monitoring and control unit is also electrically connected to the packaging cooling tower, the third valve, and the fourth valve, respectively. The monitoring and control unit is also used to receive the opening and closing signals of the packaging cooling tower, and to control the opening and closing of the third valve and the fourth valve.
[0018] The technical solution provided by this utility model can include the following beneficial effects:
[0019] 1. Bottle washing water can be directly recycled and used for makeup water for packaging cooling towers, makeup water for brewing cooling towers, and toilet flushing, saving a lot of water resources without the need for additional treatment equipment and costs.
[0020] 2. A monitoring and control system is added to the low-level water tank to monitor the water quality of the bottle washing water. Collection via an emergency tank allows for timely collection of contaminated bottle washing water in case of contamination, facilitating subsequent wastewater treatment. This provides sufficient time to handle unexpected problems before the emergency tank fills up. This addresses the issue of changes in bottle washing water quality affecting cooling tower operation, or the accidental inflow of wastewater from other processes into the domestic wastewater system via toilets.
[0021] 3. By setting up a low-level water tank, it is easy to collect bottle washing water. By transferring the bottle washing water collected in the low-level water tank to the high-level water tank, the bottle washing water is distributed and used through multiple water channels under the action of gravity, resulting in more stable water pressure and water volume distribution, and making it easier to control and distribute the water volume.
[0022] 4. The second pipe serves as the main outlet pipe connecting the elevated water tank to the brewing cooling tower, with its water flow controlled by the first valve. The third pipe, as a branch pipe connecting to the packaging cooling tower, has its water flow controlled by the second valve. The fourth pipe connects to the toilet, with the connection status controlled as needed by the toilet's flushing equipment. This structure allows for convenient adjustment of the water flow to the packaging cooling tower side and the brewing cooling tower and toilet side by adjusting the opening of the second and third valves.
[0023] 5. By manually controlling the opening of the gate valve, the water flow in the second and third pipes is simply distributed. The opening of the second valve is set to 3 / 4 to increase the pressure in the pipe and enhance the distribution effect. The opening of the third valve is smaller than that of the second valve to ensure that the water flow in the second pipe is greater than that in the third pipe, so that most of the water flows to the brewing cooling tower and toilet side where the water consumption is greater.
[0024] 6. When the packaging cooling tower is not running, by closing the first valve and opening the fourth valve, the first one-way valve will automatically close under water pressure. The water pump outlet will enter the second pipe through the fifth pipe. The water flow will no longer pass through the high-level water tank, reducing the conveying distance of the bottle washing water, reducing friction loss, increasing the pumping efficiency of the water pump, and reducing energy consumption.
[0025] 7. The monitoring and control unit automatically adjusts the opening and closing of the first and fourth valves according to the operation of the packaging cooling tower, and switches the water flow path in a timely manner to reduce the intensity of manual operation.

[0035] The embodiments of this utility model are described below with reference to the accompanying drawings.
[0036] A bottle washing water recycling system includes a low-level water tank 1, a high-level water tank 2, a water pump 3, a monitoring and control unit 4, and an emergency pool 41. The low-level water tank collects bottle washing water discharged from an upstream bottle washing device 9. The inlet of the water pump 3 is connected to the bottom of the low-level water tank 1 via a pipe, and the outlet of the water pump 3 is connected to the top of the high-level water tank 2 via a first pipe 11. The first pipe 11 is equipped with a first valve 81. The outlet of the water pump is also connected to the emergency pool 41 via an emergency pipe, which is equipped with an emergency valve 42. The bottom of the high-level water tank 2 has an outlet, which is connected to at least several pipes. Three water lines are connected, one of which is connected to the water storage tank of the packaging cooling tower 5, another to the water storage tank of the brewing cooling tower 6, and the third to the water inlet unit for flushing water in the toilet 7. Each water line is equipped with an independent valve. The first valve 81 and the emergency valve 42 are electrically connected to the monitoring and control unit. The monitoring and control unit is used to monitor whether the water entering the low-level water tank is normal bottle washing water. When the bottle washing water is detected to be contaminated, the monitoring and control unit 4 controls the first valve 81 to close and the emergency valve 42 to open. The emergency pool 42 is used to collect the contaminated bottle washing water in an emergency.
[0037] The bottle washing water is tap water filtered through a filter cloth and is used only to clean the inside and surface of glass bottles, removing dust and dirt. Under normal operating conditions, the bottle washing water contains only a small amount of dust and impurities. Packaging and brewing cooling towers require a large amount of water for production, and toilet flushing is a stable source of water use. Since these areas do not have high requirements for water cleanliness, the bottle washing water can be directly recycled and reused for packaging and brewing cooling tower water replenishment and toilet flushing, saving significant water resources without the need for additional treatment equipment and costs.
[0038] However, due to the complexity of the production process, to prevent accidental spills or leaks of other materials into the bottle washing water due to contamination of glass bottles or pipe ruptures / blockages, thus contaminating the washing water, and without increasing treatment costs, to ensure the stability of the transferred washing water quality and prevent impact on the operation of packaging cooling tower 5 and brewing cooling tower 6, and to ensure that industrial wastewater does not mix with the washing water and accidentally flow into domestic wastewater via toilet 7, a monitoring and control system is added to the low-level water tank 1 to monitor the water quality of the washing water. Collection via an emergency pool allows for timely collection of contaminated washing water in the event of contamination, facilitating subsequent wastewater treatment. Sufficient time is provided to handle unexpected problems before the emergency pool fills. This addresses the issue of changes in washing water quality affecting cooling tower operation, or the accidental inflow of wastewater from other processes into domestic wastewater via toilet 7.
[0039] like Figure 1 As shown, by setting up a low-level water tank 1, it is convenient to collect bottle washing water. By transferring the bottle washing water collected in the low-level water tank 1 to the high-level water tank, the bottle washing water is distributed and used through multiple water pipes under the action of gravity, resulting in more stable water pressure and water volume distribution, which facilitates the regulation and distribution of water volume.
[0040] Toilet 7 is equipped with a water tank for storing water for flushing. The water inlet unit of the toilet is equipped with an automatic overflow preventer. The water inlet unit is connected to both the tap water pipe and the fourth pipe 14. The tap water pipe is equipped with a tap water inlet valve. When bottle water is used for flushing toilet 7, the opening of the tap water inlet valve is reduced. When the water tank needs to be replenished, the automatic overflow preventer opens, and both bottle water and tap water are replenished simultaneously. When bottle water is available, the amount of tap water used can be reduced, saving water costs. At the same time, it prevents toilet 7 from running out of water when the bottle water supply stops.
[0041] Preferably, the elevated water tank 2 is connected to the brewing cooling tower 6 through the second pipe 12, the packaging cooling tower 5 is connected to the second pipe 12 through the third pipe 13, and the toilet 7 is connected to the second pipe 12 through the fourth pipe 14. The connection point between the third pipe 13 and the second pipe 12 is point a, and the connection point between the fourth pipe 14 and the second pipe 12 is point b. Point a is located between point b and the elevated water tank.
[0042] The second pipe 12 is equipped with a second valve 82, which is located between point a and point b. The third pipe 13 is equipped with a third valve 83. The second valve 82 is used to distribute the water flow in the second pipe 12, and the third valve 83 is used to distribute the water flow in the third pipe 13.
[0043] like Figure 2 As shown, the second pipe serves as the main outlet pipe connecting the elevated water tank 1 to the brewing cooling tower, with its water flow controlled by the first valve. The third pipe serves as a branch pipe connecting to the packaging cooling tower, with its water flow controlled by the second valve. The fourth pipe 14 connects to the toilet, with the connection status controlled as needed by the toilet's flushing equipment. With this structure, the water flow to the packaging cooling tower 5 side and the brewing cooling tower 6 and toilet 7 side can be easily adjusted by regulating the opening of the second valve 82 and the third valve 83.
[0044] Preferably, the nominal diameter of the second pipe 12 is 80mm, the nominal diameter of the third pipe 13 is 75mm, the second valve 82 and the third valve 83 are both gate valves, the opening degree of the second valve 82 is set to 3 / 4, and the opening degree of the third valve 83 is smaller than that of the second valve 82.
[0045] In one embodiment, the water flow in the second pipe 12 and the third pipe 13 is simply distributed by manually controlling the opening of the gate valve. The opening of the second valve 82 is set to 3 / 4 to increase the pressure inside the pipe and enhance the distribution effect. The opening of the third valve 83 is less than that of the second valve 82, ensuring that the water flow in the second pipe 12 is greater than that in the third pipe 13, so that most of the water flows to the brewing cooling tower 6 and the toilet 7, which have a larger water consumption.
[0046] Preferably, the outlet of the water pump 3 is also connected to the second pipe 12 through a fifth pipe 15, and the connection point between the fifth pipe 15 and the second pipe 12 is point c, which is located between point a and point b. The first pipe 11 is provided with a first valve 81, the fifth pipe 15 is provided with a fourth valve 84, and the second pipe 12 is provided with a first one-way valve 85 between point a and point c. The communication direction of the first one-way valve 85 is from point a to the connection point c.
[0047] The packaging cooling tower 5 is mainly used for air conditioning cooling in the packaging workshop. It can be used to operate a single production line, or in autumn and winter when the temperature inside the workshop is not high and the air conditioning is not in use.
[0048] When the packaging cooling tower 5 is running, the first valve 81 remains open and the fourth valve 84 remains closed. The water from the pump 3 enters the high-level water tank 2 and then enters the second pipe 12.
[0049] like Figure 3 As shown, when the packaging cooling tower 5 is not running, by closing the first valve 81 and opening the fourth valve 84, the first one-way valve 85 automatically closes under water pressure, and the water from the water pump 3 enters the second pipe 12 through the fifth pipe 15. The water flow no longer passes through the high-level water tank 2, which shortens the conveying distance of the bottle washing water, reduces friction loss, increases the pumping efficiency of the water pump 3, and reduces energy consumption.
[0050] Preferably, the monitoring and control unit 4 includes a pH meter.
[0051] pH value is a basic monitoring indicator. The pH value of bottle washing water and tap water is the same, stable between 6.5 and 8.5. The pH meter sends the measured value to the monitoring control unit. When the current pH value exceeds 6.5 to 8.5, the monitoring control unit determines that the bottle washing water is contaminated. The monitoring control unit controls the first valve (81) to close and opens the emergency valve (42). The introduction of the pH meter can monitor the changes in acidity and alkalinity of the water in real time, promptly detect changes in water quality that are too acidic or too alkaline, and avoid adverse effects on equipment and production processes.
[0052] Preferably, the monitoring and control unit 4 includes a conductivity meter.
[0053] The conductivity meter effectively monitors the concentration of ions in water. As the amount of inorganic matter in the water increases, the conductivity increases. The conductivity of bottle washing water and tap water is the same, not exceeding 2000 μS / cm. The conductivity meter sends the measured conductivity to the monitoring and control unit. When the conductivity exceeds 2000 μS / cm, the monitoring and control unit determines that the bottle washing water is contaminated. The monitoring and control unit then closes the first valve 81 and opens the emergency valve 42.
[0054] Preferably, the monitoring and control unit 4 includes an online COD detection device.
[0055] The online COD monitoring device can accurately monitor the concentration of organic matter in water, promptly detect changes in organic matter in the water quality, and ensure that the use of bottle washing water meets environmental protection requirements, with the COD content of the bottle washing water not exceeding 20 mg / L. The online COD monitoring device sends the measured COD value to the monitoring and control unit. When the COD value exceeds 20 mg / L, the monitoring and control unit determines that the bottle washing water is contaminated, controls the first valve 81 to close, and opens the emergency valve 42.
[0056] Preferably, the low-level water tank 1 is equipped with a liquid level sensor 100, and the monitoring and control unit 4 is electrically connected to the liquid level sensor 100 and the water pump 3.
[0057] The bottle washing water is first collected and temporarily stored in the low-level water tank 1. When the water level reaches the high level of the liquid level sensor 100, the monitoring and control unit controls the water pump 3 to start and transport it to the high-level water tank 2 through the first pipeline 11 for storage. When the liquid level in the low-level water tank 1 reaches the low level of the liquid level sensor 100, the monitoring and control unit controls the water pump 3 to stop.
[0058] Preferably, the first pipeline 11 is provided with a second one-way valve 86, and the communication direction of the second one-way valve 86 is from the low-level water tank 1 to the high-level water tank 2.
[0059] Adding a second check valve 86 prevents water in the first pipeline 11 from flowing back to the low-level water tank 1, thereby improving the conveying efficiency.
[0060] Preferably, the monitoring and control unit is also electrically connected to the packaging cooling tower, the third valve, and the fourth valve, respectively. The monitoring and control unit is also used to receive the opening and closing signals of the packaging cooling tower, and to control the opening and closing of the third valve and the fourth valve.
[0061] Based on the operating status of the packaging cooling tower, the monitoring and control unit automatically adjusts the opening and closing of the first and fourth valves, switches the water flow path in a timely manner, and reduces the intensity of manual operation.
[0062] It should be noted that the monitoring and control unit includes a controller, which is communicatively connected to the aforementioned pH meter, conductivity meter, online COD detection device, first valve 81, second valve 82, third valve, fourth valve, emergency valve 42, first check valve 85, second check valve 86, and level sensor 100. All control commands mentioned above can be issued by the controller.
