DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1: In the prior art, after the bottle washing machine completes the washing process of the liquor bottles, a large amount of bottle washing water containing dirt and impurities will be generated. If this bottle washing water is directly discharged into the natural environment without being treated, it is very easy to cause environmental pollution. At the same time, as a precious resource, if the bottle washing water is frequently discharged without being utilized, it will not only waste water resources, but also increase the production cost of the enterprise.

[0025] Therefore, in order to solve the problem that the existing bottle washing machine directly discharges sewage when washing liquor bottles, causing environmental pollution and cost increase, and to achieve the function of reducing pollution, saving energy and reducing emissions, the utility model discloses a bottle washing water recovery and filtering device, referring to Figure 1 , including a return water tank 1 for receiving wastewater from a bottle washing machine, a primary filter membrane group 2 and a secondary filter membrane group 3 for filtering the wastewater in the return water tank 1, and a return water pipe 12 for re-introducing the filtered water into the bottle washing machine. Specifically, the water inlet of the return water tank 1 is connected to the water outlet of an external bottle washing machine through a pipeline, the return water pipe 12 is connected to the water inlet of the external bottle washing machine, and the return water tank 1, the primary filter membrane group 2, the secondary filter membrane group 3 and the return water pipe 12 are sequentially connected through a water pipe;

[0026] The reflux water tank 1 can receive the sewage discharged from the water outlet of the bottle washing machine, and then introduce the sewage into the primary filter membrane group 2 through a water pipe for the first filtration. After the sewage is filtered by the primary filter membrane group 2, it will be introduced into the secondary filter membrane group 3 for secondary filtration. Finally, the bottle washing water that has been filtered twice will be re-introduced into the water inlet of the bottle washing machine through the return pipe 12 for secondary utilization. Through the above structure, the recovery and filtration device can effectively avoid environmental pollution and cost increase compared with the bottle washing machine in the prior art.

[0027] In the above embodiment, the primary filter membrane group 2 and the secondary filter membrane group 3 both include a plurality of filter membrane columns arranged side by side, wherein the primary filter membrane group 2 is composed of a filter membrane column with a PVDF ultrafiltration membrane, adopting a cross-flow filtration method, and the secondary filter membrane group 3 is composed of a filter membrane column with an MBR membrane filtration, adopting a negative pressure osmosis filtration method.

[0028] In the above embodiment, both the primary filter membrane group 2 and the secondary filter membrane group 3 include a plurality of filter membrane columns arranged side by side, each of which uses a different type of filter membrane and a unique filtering technology to achieve an efficient and stable filtering effect.

[0029] The first-stage filter membrane group 2 uses PVDF ultrafiltration membrane, which has the characteristics of high flux and low protein adsorption, making it widely used in food, medicine and other fields. The high mechanical strength and toughness, as well as the antifungal and high wear resistance of the PVDF ultrafiltration membrane ensure that it has a long service life and stable filtration performance during use. As the core technology of the first-stage filter membrane group, the cross-flow filtration technology enables the raw water to form a thin water layer on the surface of the filter membrane, achieving efficient filtration while reducing the risk of clogging of the filter membrane, thereby extending the service life of the filter membrane.

[0030] The secondary filter membrane group 3 uses MBR membrane filtration technology, which combines the advantages of biological treatment and membrane separation, and can achieve deep treatment of pollutants in water. Negative pressure osmosis filtration technology is the key to the secondary filter membrane group. It uses pressure difference to make water molecules pass through the membrane pores more easily, thereby improving filtration efficiency. At the same time, negative pressure osmosis technology can also effectively remove pollutants such as organic matter and heavy metals in the water, ensuring that the effluent water quality reaches higher standards.

[0031] In this embodiment, see Figure 2 A raw water pump 8 is provided on the water pipe between the return water tank 1 and the primary filter membrane group 2, and the sewage in the return water tank 1 can be pumped into the primary filter membrane group 2 for filtering treatment through the raw water pump 8. At the same time, in order to ensure the filtering effect and the stable operation of the system, a flow meter and a pressure gauge are also provided on the water pipe between the return water tank 1 and the primary filter membrane group 2.

[0032] The flow meter is used to monitor the flow of sewage entering the primary filter membrane group 2 in real time to ensure that the flow is within the appropriate range to avoid excessive or insufficient flow causing excessive impact on the filter membrane or affecting the filtering effect. When the flow is abnormal, the flow meter will sound an alarm to remind the operator to check and handle it in time.

[0033] The pressure gauge is used to monitor the pressure changes in the water pipe to ensure that the water flow is stable and does not cause excessive pressure on the primary filter membrane group 2.

[0034] In addition, in order to ensure the safety and reliability of the system, the water pipe between the reflux water tank 1 and the primary filter membrane group 2 is also made of corrosion-resistant and high-pressure resistant materials to prevent accidents.

[0035] In this embodiment, see Figure 2 A water production valve 9 is provided on the water pipe between the primary filter membrane group 2 and the secondary filter membrane group 3. The water production valve 9 can control the opening and closing of the water pipe between the primary filter membrane group 2 and the secondary filter membrane group 3. The water in the primary filter membrane group 2 can be introduced into the secondary filter membrane group 3 for secondary filtration through the water production valve 9.

[0036] In this embodiment, see Figure 2A booster pump 11 is provided on the water pipe between the secondary filter membrane group 3 and the return pipe 12. The booster pump 11 can pump water in the secondary filter membrane group 3 to the return pipe 12, so that the filtered bottle washing water can smoothly return to the bottle washing machine.

[0037] In the above embodiment, the booster pump 11 can perform forward or reverse boosting. When the booster pump 11 performs forward boosting, water is pumped from the secondary filter membrane group 3 into the bottle washing machine. When the booster pump 11 performs reverse boosting, clean water at the return pipe 12 can be pumped back into the secondary filter membrane group 3 and the primary filter membrane group 2, thereby backwashing and cleaning the filter device.

[0038] Example 2: Based on Example 1, with daily wine bottle cleaning or after a long period of downtime, the filter membrane will retain the fine particles and microorganisms left behind, causing the bacteria in the membrane to grow and multiply, causing the filter membrane to be blocked to varying degrees. Therefore, in order to avoid the above problems, refer to Figure 2 The filtering device also includes an electric heating tube 7 and an aeration plate 6 for assisting in cleaning the filter membrane. Specifically, the interior of the reflux water tank 1 is provided with an electric heating tube 7 for heating water, the bottom surface of the reflux water tank 1 is provided with an aeration plate 6, and the bottom of the reflux water tank 1 is provided with an air pump 5 for starting the aeration plate 6.

[0039] When the filter membrane group needs to be cleaned, the user can first fill the reflux water tank 1 with clean water, and then pour the sodium hydroxide particles into the reflux water tank 1 to dissolve them. At this time, the electric heating tube 7 can heat the cold water in the reflux water tank 1, and the aeration plate 6 can be driven by the air pump 5 to aerate the reflux water tank 1, so that the water body can be stirred, so that the water body can be quickly mixed with the sodium hydroxide particles and dissolved, and then the sodium hydroxide solution is pumped into the primary filter membrane group 2 through the raw water pump 8 to clean the blocked attachments on the filter membrane. At the same time, since hot water is used for cleaning, the hot water can expand the filter pores on the surface of the filter membrane, further improving the cleaning efficiency of the filter membrane.

[0040] When cleaning the filter membrane group, the user must also pay attention to controlling the concentration and temperature of the sodium hydroxide solution to avoid damaging the filter membrane. After the primary filter membrane group 2 is cleaned with the sodium hydroxide solution, most of the clogging attachments will be effectively removed, and the permeability of the filter membrane will be significantly improved.

[0041] In addition, as a further stage of filtration, the secondary filter membrane group 3 may have accumulated finer particles and impurities on its filter membrane surface. In order to clean the filter membrane group more comprehensively, the user can open the water production valve 10 to allow the sodium hydroxide solution in the primary filter membrane group 2 to flow into the secondary filter membrane group 3, so that the user can regularly perform the same cleaning operation on the secondary filter membrane group 3. Therefore, by introducing the sodium hydroxide solution for cleaning, these stubborn blockages can be effectively removed to ensure the long-term stable operation of the filter membrane group.

[0042] During the cleaning process, users also need to pay close attention to the working status of the filter group. If the filter group is found to be abnormal, such as the filter membrane is damaged or the cleaning effect is poor, the cleaning operation should be stopped in time, and the filter group should be inspected and repaired. At the same time, in order to extend the service life of the filter group, users should regularly maintain and maintain the filter group to ensure that it is in the best working condition.

[0043] Therefore, by using sodium hydroxide solution to clean the filter membrane group with hot water, the clogging attachments on the filter membrane can be effectively removed, the permeability of the filter membrane can be improved, and the normal operation of the filtration system can be ensured. At the same time, users should also pay attention to controlling the parameters and details during the cleaning process to ensure the cleaning effect and the safety and stability of the filter membrane group.

[0044] In this embodiment, see Figure 2 A tap water inlet 4 is provided at the opening of the return water tank 1, through which the user can introduce external tap water into the return water tank 1 as cleaning water.

[0045] In this embodiment, see Figure 2 A drain valve 10 and a drain pipe are provided at the bottom of the primary filter membrane group 2. By opening the drain valve 10, the backwash sewage of the filtration device and the sewage used to clean the filter membrane can be discharged from the drain pipe.

[0046] Embodiment 3, based on Embodiment 1 and Embodiment 2, in order to further improve the mixing efficiency of the clean water and the sodium hydroxide particles in the reflux water tank 1, refer to Figure 3 The utility model also includes a guide plate 14 for accelerating the flow rate of clean water. Specifically, a water inlet 13 is provided at the opening of the return water tank 1, and the water inlet 13 is arranged parallel to the lower part of the tap water inlet 4. Two guide plates 14 are arranged opposite to each other inside the water inlet 13, wherein the guide plates 14 are arranged at a downwardly inclined angle;

[0047] When the tap 4 pours clean water into the return water tank 1, the water inlet 13 will receive the clean water, and then the clean water will flow along the guide plate 14 in the water inlet 13. Since the guide plate 14 is set at a downward tilted angle, the clean water will form a vortex-shaped water flow in the water inlet 13 under the guidance of gravity and the tilted angle, thereby accelerating the flow rate of the clean water in the return water tank 1. In addition, with the use of the aeration plate 6, the clean water can be quickly mixed with the sodium hydroxide particles, thereby improving the dissolution efficiency of the sodium hydroxide particles.

[0048] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0049] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
