Description

Technical Field

[0001] The utility model relates to the technical field of solution dilution, in particular to an automatic dilution device for high-concentration sodium hypochlorite solution. Background Art

[0002] As a commonly used disinfectant, sodium hypochlorite solution is widely used in many fields such as medical care, water treatment, and food processing. However, the stability of sodium hypochlorite solution has always been an important issue in its application process, especially high-concentration sodium hypochlorite solution. Due to its high effective chlorine content and rapid degradation rate, it is not easy to store and use for a long time. This limits its application in certain scenarios that require long-term storage or slow release of disinfection effects. At present, in order to solve the problem of rapid degradation of high-concentration sodium hypochlorite solution, a common method is to configure it into a low-concentration solution by dilution. In different application scenarios, the dilution ratio of high-concentration sodium hypochlorite solution is different. In order to meet the needs of different occasions and achieve the purpose of dilution of different ratios, each time before dilution, it is necessary to manually prepare the corresponding proportion of high-concentration sodium hypochlorite solution and water, which is time-consuming and labor-intensive, and has low efficiency and cannot meet the needs of automated configuration. In addition, high-concentration sodium hypochlorite solution is prone to produce a small exothermic reaction during the dilution process, which causes the dilution environment temperature to rise, accelerating the decomposition of high-concentration sodium hypochlorite and releasing toxic gases, endangering the safety of operators. During the dilution process, due to the increase in ambient temperature, water mist is easily generated, resulting in an inaccurate ratio of water to sodium hypochlorite solution, so that the concentration of the diluted solution deviates from the preset concentration, affecting the subsequent use effect.

[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0037] As a disinfectant, sodium hypochlorite solution is widely used in many fields, but its stability problem, especially the degradation rate of high-concentration solution, limits its application in long-term storage and slow release of disinfection effect. The dilution method is often used to solve the degradation problem, but different dilution ratios are required for different occasions. Manual mixing is time-consuming and labor-intensive, and it is difficult to meet automation requirements. The tiny exothermic reaction generated during the dilution process can easily lead to accelerated decomposition of the solution, release toxic gases, and threaten safety. At the same time, the water mist phenomenon caused by the increase in temperature affects the ratio accuracy, resulting in concentration deviation and affecting the use effect.

[0038] To solve the above problems, please refer to Figure 1 The present utility model embodiment provides a high-concentration sodium hypochlorite solution automatic dilution device, comprising:

[0039] The raw water supply pipeline 10 is used to provide dilution water to ensure a stable supply of water during the dilution process and to ensure that the dilution process can proceed continuously.

[0040] The softening water device 20 is used to reduce the hardness of the dilution water, reduce the impurities and minerals in the dilution water, and improve the purity and stability of the diluted sodium hypochlorite solution. The raw water supply pipeline 10 is installed at the water inlet end of the softening water device 20. The water outlet end of the softening water device 20 is provided with a first water outlet branch pipe 21 and a second water outlet branch pipe 22. According to different conditions, the output of softened dilution water with different flow rates is controlled to meet the needs of different dilution ratios and application conditions. The first water outlet branch pipe 21 and the second water outlet branch pipe 22 are respectively installed with a first flow control component 23 and a second flow control component 24 to accurately adjust the flow of each branch pipe to ensure the accuracy of the dilution ratio. The water outlet end of the first water outlet branch pipe 21 is installed with a connecting device 25, which plays a role of connection and diversion. The connecting device 25 is provided with a first connection port and a second connection port. A mixing guide pipe 26 is installed on the first connection port, and the mixing guide pipe 26 has a diversion and heat dissipation function.

[0041] The liquid medicine feeding pipe 30 is used to provide a high-concentration sodium hypochlorite solution to ensure the continuous supply of the high-concentration sodium hypochlorite solution. The liquid medicine feeding pipe 30 is installed on the second connecting port so that the high-concentration sodium hypochlorite solution and the softened dilution water can enter the mixing guide pipeline 26 at the same time. The liquid medicine feeding pipe 30 is also installed with a third flow control component 31 to accurately control the flow of the high-concentration sodium hypochlorite solution to ensure the accuracy of the dilution ratio.

[0042] The liquid storage dilution device 40 is a core component of the dilution process. It is provided with a first rapid mixing pipe 41 and a second rapid mixing pipe 42 to achieve rapid and uniform mixing and ensure the dilution effect. The outflow end of the mixing guide pipeline 26 extends into the liquid storage dilution device 40 and is connected to the first rapid mixing pipe 41. The water outlet end of the second water outlet branch pipe 22 extends into the liquid storage dilution device 40 and is connected to the second rapid mixing pipe 42. The liquid storage dilution device 40 has a first dilution state, a second dilution state and a third dilution state. The dilution ratio and strategy are adjusted according to different needs and conditions to meet the disinfection needs of different occasions and cope with different dilution conditions.

[0043] The control device serves as the core control unit of the entire dilution device to realize automatic control and precise adjustment. The first flow control component 23, the second flow control component 24 and the third flow control component 31 are all electrically connected to the control device to ensure that each component can be precisely adjusted according to the preset dilution ratio and parameters to realize an automated dilution process. Through the precise control of the control device, not only the accuracy and efficiency of the dilution can be improved, but also the labor intensity of the operator can be reduced to meet the needs of large-scale and high-efficiency disinfection. At the same time, the control device can also monitor and adjust the dilution process in real time to ensure the stability and reliability of the dilution effect.

[0044] In this embodiment, when the liquid storage dilution device 40 is in the first dilution state, the second flow control component 24 is turned on, and the second water outlet branch pipe 22 transports a preset amount of dilution water to the liquid storage dilution device 40 through the second rapid mixing pipe 42, and the dilution water immerses the first rapid mixing pipe 41, creating and providing a liquid dilution environment to avoid splashing and misting during the dilution process. The first flow control component 23 and the third flow control component 31 are turned on, and the first water outlet branch pipe 21 and the liquid medicine feed pipe 30 supply dilution water and high-concentration sodium hypochlorite solution respectively at the same time, and transport them to the first rapid mixing pipe 41 through the mixing guide pipe 26. The dilution water and the high-concentration sodium hypochlorite solution are initially diluted and merged in the mixing guide pipe 26. After the initially diluted solution enters the first rapid mixing pipe 41, it is further diluted to obtain a rapid and uniform mixing effect.

[0045] When the liquid storage dilution device 40 is in the second dilution state, the second water outlet branch 22 does not work, the first flow control component 23 is opened, and the second flow control component 24 is closed. The first water outlet branch 21 transports a preset amount of dilution water to the liquid storage dilution device 40 through the first rapid mixing channel, and the dilution water soaks the first rapid mixing channel to create and provide a liquid dilution environment to avoid splashing and misting during the dilution process. Then, the first flow control component 23 is closed, the third flow control component 31 is opened, and the liquid feeding pipe 30 supplies a preset amount of high-concentration sodium hypochlorite solution, and transports it to the first rapid mixing pipeline 41 through the mixing guide pipeline 26.

[0046] When the liquid storage dilution device 40 is in the third dilution state, the first flow control component 23 is closed, the second flow control component 24 is opened, the second water outlet branch pipe 22 supplies a preset amount of dilution water to the liquid storage dilution device 40 through the second rapid mixing channel, and the dilution water soaks the first rapid mixing channel, the second flow control component 24 is closed, the third flow control component 31 is opened, the liquid feeding pipe 30 supplies a preset amount of high-concentration sodium hypochlorite solution, and is transported to the first rapid mixing pipeline 41 through the mixing guide pipeline 26.

[0047] The dual-pipe design provides backup and redundancy functions. When one of the outlet branches fails or requires maintenance, the other outlet branch can continue to work and use the dilution water to soak the first rapid mixing channel to create a liquid dilution environment, ensuring the continuity and stability of the overall dilution system.

[0048] It should be noted that when the liquid storage dilution device 40 is in the first dilution state, both pipes are in working state, the mixing and conveying speed is accelerated, and a secondary dilution strategy is adopted to improve the stability and accuracy of the dilution process. In addition, different pipes have different mixing characteristics to meet the mixing requirements of sodium hypochlorite liquid with different concentrations and softened dilution water, which helps to achieve a more accurate and efficient mixing process.

[0049] The liquid storage and dilution device 40 is used to perform liquid dilution operations and store diluted liquid medicine. Such a design can ensure the safety and stability of the dilution process, and is convenient for storage and subsequent use. The first rapid mixing pipe 41 and the second rapid mixing pipe 42 are both provided with a turbulent structure. The turbulent structure is used to enhance the mixing effect of the dilution water and the high-concentration sodium hypochlorite solution, ensure the quality and uniformity of the diluted liquid medicine, improve the dilution efficiency, and ensure that the concentration of the diluted sodium hypochlorite solution is stable to meet the use requirements. The first rapid mixing pipe 41 is located above the second rapid mixing pipe 42. Such a layout is conducive to the flow of liquid in a certain order, further ensuring the uniformity and effect of mixing.

[0050] Furthermore, the first flow control component 23 includes a first regulating valve 231, a first electric valve 232 and a first check valve 233, which are installed in sequence on the first water outlet branch 21 along the dilution water supply direction, and the second flow control component 24 includes a second regulating valve 241, a second electric valve 242 and a second check valve 243, which are installed in sequence on the second water outlet branch 22 along the dilution water supply direction.

[0051] Specifically, the first regulating valve 231 and the second regulating valve 241 are used to finely adjust the flow rate, the first electric valve 232 and the second electric valve 242 are responsible for quickly responding to the control signal of the control device to open and close the valves, and the first check valve 233 and the second check valve 243 effectively prevent the occurrence of fluid backflow. By accurately controlling the flow rate of the first water outlet branch pipe 21 and the second water outlet branch pipe 22, efficient and safe dilution of high-concentration sodium hypochlorite solution is achieved, making the entire dilution device more flexible and reliable.

[0052] The third flow control component 31, as a key control component, plays a vital role in accurately adjusting the flow of the high-concentration sodium hypochlorite solution. The third flow control component 31 includes a control valve 311 and a third check valve 312, which work together to ensure the stability and accuracy of the flow of the high-concentration sodium hypochlorite solution. Among them, the control valve 311 is responsible for fast and accurate flow adjustment according to preset parameters and real-time feedback signals to meet the needs of different dilution ratios, and the third check valve 312 can effectively prevent the backflow of the liquid, ensuring the safety of the supply of the high-concentration sodium hypochlorite solution.

[0053] In addition, the control valve 311 and the third check valve 312 are sequentially installed on the liquid medicine feeding pipe 30 along the supply direction of the high-concentration sodium hypochlorite solution to ensure that the liquid medicine is effectively controlled and protected during the flow process.

[0054] The water supply pressure of dilution water is 0.2~0.4MPa, which ensures the stable supply and efficient mixing of dilution water and avoids the adverse effects of excessive or low water pressure on the equipment.

[0055] Here, too low water pressure will cause the water flow rate to be too slow, affecting the efficiency of the dilution process, while too high water pressure will easily cause safety hazards such as pipeline rupture and leakage. By setting it within the range of 0.2 to 0.4 MPa, it can ensure that the dilution water flows at an appropriate flow rate in the pipeline and is fully mixed with the high-concentration sodium hypochlorite solution, ensuring that the concentration of the diluted sodium hypochlorite solution is stable and reliable.

[0056] In addition, by properly controlling the water supply pressure, the energy consumption and operating costs of the equipment can be reduced, thereby improving the overall economic benefits.

[0057] Furthermore, the mixing guide pipeline 26 is a corrosion-resistant heat dissipation pipeline, which ensures that the pipeline can operate stably for a long time, avoids heat accumulation during the dilution process, maintains the temperature stability of the solution, and improves the dilution effect.

[0058] A magnetic flap level gauge 50 is also installed on the liquid storage and dilution device 40. The magnetic flap level gauge 50 provides accurate data support for the operator by real-time monitoring of the liquid level changes in the liquid storage and dilution device 40, which helps to accurately control the dilution process.

[0059] At the same time, the magnetic flap level gauge 50 is also provided with an alarm device, which promptly issues an alarm when the liquid level is too high or too low, thereby ensuring the normal operation of the overall dilution device and the quality of solution dilution.

[0060] A pipeline diverter 60 is provided at the water outlet end of the softening water device 20, and a first water outlet and a second water outlet are provided on the pipeline diverter 60. The first water outlet branch pipe 21 and the second water outlet branch pipe 22 are respectively installed on the first water outlet and the second water outlet, so as to realize the branch supply of the softened dilution water and ensure the water outlet stability and reliability of the first water outlet branch pipe 21 and the second water outlet branch pipe 22.

[0061] The connecting device 25 is a three-way joint, which connects different pipelines together to achieve the mixing and transportation of high-concentration sodium hypochlorite and dilution water. The three-way joint has the characteristics of compact structure and reliable connection, which not only simplifies the device structure and improves work efficiency, but also provides a strong guarantee for the stable operation of the device.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
