Operators can observe the leaked liquid and liquid level through the strip-shaped observation window, providing a leak prevention warning function.

Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and more specifically, to a sodium hydroxide solution storage tank. Background Technology

[0002] Sodium hydroxide solution storage tanks (also known as alkali storage tanks) are industrial containers specifically designed for storing sodium hydroxide (NaOH) solutions. Because sodium hydroxide is highly corrosive, the design of the storage tanks must meet corrosion resistance requirements; otherwise, long-term corrosion of the storage tanks will lead to leakage of the sodium hydroxide solution.

[0003] Common sodium hydroxide solution storage tanks can only store sodium hydroxide solution, but they lack leak-proof warning functions. During daily storage, the tank may crack and leak due to the strong corrosiveness of sodium hydroxide solution. Leaks not only cause the loss of valuable chemical raw materials, but also cause serious chemical burns when in contact with skin or eyes. Inhalation of alkaline mist can burn the respiratory mucosa, ultimately leading to increased production costs and safety issues.

[0004] In summary, to address both production costs and safety, it is necessary to resolve the issue of sodium hydroxide solution leakage, ensuring that any leaks can be collected and the leakage can be visually observed. Utility Model Content

[0005] The sodium hydroxide solution storage tank provided by this utility model aims to solve the problem that the tank body will crack and leak due to the strong corrosiveness of sodium hydroxide solution, and the leaked sodium hydroxide solution cannot be collected.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sodium hydroxide solution storage tank, comprising a lower tank body, four support legs installed at the lower end of the lower tank body, an upper tank body provided at the upper end of the lower tank body, an inner storage tank provided inside the lower and upper tank bodies, a triangular guide plate installed on the inner side of the lower tank body, two collection boxes installed at the lower end of the lower tank body, a strip-shaped observation window provided on the surface of the collection boxes, a drain port provided on the surface of the collection boxes, a functional mechanism provided on the inner storage tank body, and a liquid storage mechanism provided on the inner storage tank body and the lower tank body.

[0007] In a preferred embodiment, the functional mechanism is used to adjust the liquid storage state. The functional mechanism includes a liquid filling and draining assembly and a pressure relief assembly. The liquid filling and draining assembly is used to add liquid to or drain sodium hydroxide solution from the inner storage tank. The pressure relief assembly is used to monitor and relieve pressure in the inner storage tank.

[0008] In a preferred embodiment, the liquid filling and draining assembly includes two liquid filling ports installed at the upper end of the inner tank and two liquid draining valve pipes installed at the lower end of the inner tank.

[0009] In a preferred embodiment, the pressure relief assembly includes two pressure relief valve connecting pipes installed at the upper end of the inner tank and two pressure gauge mounting pipes installed at the upper end of the inner tank.

[0010] In a preferred embodiment, the liquid storage mechanism is used to store sodium hydroxide solution in separate sections. The liquid storage mechanism includes a partitioning component and a barrier component. The partitioning component is used to store sodium hydroxide solutions of different concentrations in separate sections, and the barrier component is used to prevent the inner storage tank from contacting the lower half of the tank.

[0011] In a preferred embodiment, the partitioning component includes a liquid storage chamber formed inside the inner tank and a partition plate installed inside the liquid storage chamber.

[0012] In a preferred embodiment, the barrier assembly includes four hollow sockets installed inside the lower half of the tank and four interlocking rods installed at the lower end of the inner tank, the interlocking rods being inserted into the hollow sockets.

[0013] In a preferred embodiment, a fixing assembly is provided on the lower half tank and the upper half tank. The fixing assembly is used to fix the lower half tank and the upper half tank together. The fixing assembly includes two lower slot plates installed at the upper end of the lower half tank and two upper slot plates installed at the lower end of the upper half tank. The lower slot plates and the upper slot plates are fixedly connected.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model uses the lower half of the tank and the upper half of the tank to form an outer protective shell that surrounds the inner storage tank. The solution leaking from the inner storage tank flows into the interlayer space formed by the inner storage tank, the lower half of the tank, and the upper half of the tank, and finally flows into the collection box. The leakage can be detected in time through the strip observation window, avoiding raw material loss, environmental pollution and safety accidents. The overall double-layer design combined with the fixing components ensures structural stability, improves safety, and reduces maintenance costs and production risks. Attached Figure Description

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Refer to the instruction manual appendix Figures 1 to 7 A sodium hydroxide solution storage tank includes a lower tank 1, with four support legs 11 installed at the lower end of the lower tank 1. An upper tank 12 is provided at the upper end of the lower tank 1. An inner storage tank 13 is provided inside the lower tank 1 and the upper tank 12. A triangular guide plate 14 is installed on the inner side of the lower tank 1. Two collection boxes 15 are installed at the lower end of the lower tank 1. A strip-shaped observation window 16 is provided on the surface of the collection box 15. A drain port 17 is provided on the surface of the collection box 15. A functional mechanism is provided on the inner storage tank 13. A liquid storage mechanism is provided on the inner storage tank 13 and the lower tank 1.

[0026] It should be noted that the storage tank adopts a double-layer structure design. The inner tank 13 is made of highly corrosion-resistant material and directly stores sodium hydroxide solution. The lower tank 1 and the upper tank 12 form an outer protective shell, forming a leakage collection chamber. Through the inclined design of the triangular guide plate 14, the leaked liquid can be quickly guided to the collection box 15 to avoid accumulation at the bottom of the tank and ensure that the leakage is centrally treated. The strip observation window 16 is made of transparent corrosion-resistant material, which makes it easy for operators to visually check the leakage amount. The drain port 17 can be connected to the discharge pipeline to clean the collected liquid regularly.

[0027] It is worth noting that this design not only enables proactive collection and visual monitoring of leaks, but also reduces the risk of sodium hydroxide coming into contact with the external environment, effectively preventing chemical burns and material waste, reducing maintenance costs, and ensuring that leaked liquid is safely captured instead of leaking directly when the tank cracks due to corrosion, thus improving overall safety.

[0028] Refer to the instruction manual appendix Figures 1 to 7 The functional mechanism is used to adjust the state of the stored liquid. The functional mechanism includes a liquid filling and draining assembly and a pressure relief assembly. The liquid filling and draining assembly is used to add liquid to or drain sodium hydroxide solution from the inner storage tank 13. The pressure relief assembly is used to monitor and relieve the pressure inside the inner storage tank 13.

[0029] It should be noted that the functional mechanism is the core control system of the inner storage tank 13. The liquid filling and draining components manage the loading and unloading process of the solution, while the pressure relief components monitor and regulate the internal pressure to ensure that the storage tank operates under safe parameters. The coordinated work of the liquid filling and draining components and the pressure relief components prevents pressure fluctuations or solution overflows caused by improper operation, thereby enhancing the stability and reliability of the storage tank.

[0030] Refer to the instruction manual appendix Figures 6 to 7 The liquid filling and draining assembly includes two liquid filling ports 211 installed at the upper end of the inner storage tank 13 and two liquid draining valve pipes 212 installed at the lower end of the inner storage tank 13.

[0031] It should be noted that the liquid filling port 211 is located at the upper end of the inner storage tank 13, which facilitates the injection of sodium hydroxide solution through the pipeline. The drain valve pipe 212 is located at the lower end and adopts a corrosion-resistant valve to allow the solution to be completely drained and reduce residual corrosion.

[0032] Refer to the instruction manual appendix Figure 6 The pressure relief assembly includes two pressure relief valve connecting pipes 221 installed at the upper end of the inner storage tank 13 and two pressure gauge mounting pipes 222 installed at the upper end of the inner storage tank 13.

[0033] It should be noted that the pressure relief valve connecting pipe 221 is used to install a spring-loaded or rupture disc type pressure relief valve, which automatically opens when the pressure inside the inner storage tank 13 exceeds the set threshold to release gas and prevent the tank from rupturing due to overpressure. The pressure gauge mounting pipe 222 is adapted to a standard pressure gauge to provide real-time pressure monitoring and help operators detect abnormalities in a timely manner. These components are located at the upper end of the tank, away from the solution area, to reduce the impact of corrosion.

[0034] Refer to the instruction manual appendix Figures 1 to 7 The liquid storage mechanism is used to store sodium hydroxide solution in separate sections. The liquid storage mechanism includes a partitioning component and a barrier component. The partitioning component is used to store sodium hydroxide solutions of different concentrations in separate sections, and the barrier component is used to prevent the inner storage tank 13 from contacting the lower half tank 1.

[0035] It should be noted that the liquid storage mechanism achieves the separation and storage of the solution through the partition component, while the barrier component forms a physical gap between the inner tank 13 and the lower half tank 1, preventing direct contact. The partition component allows for customized storage solutions, while the interlocking structure of the barrier component ensures the stable suspension of the inner tank, facilitating the flow of leaked liquid to the collection box 15 through the gap.

[0036] It is worth noting that the combination of partitioning and isolation not only extends the life of the tank, but also simplifies the leak detection path, making maintenance more convenient, and the overall design meets chemical storage standards.

[0037] Refer to the instruction manual appendix Figure 3 The partitioning component includes a liquid storage chamber 311 opened inside the inner storage tank 13 and a partition plate 312 installed inside the liquid storage chamber 311.

[0038] It should be noted that the liquid storage chamber 311 is divided into two independent areas by the partition plate 312. The partition plate 312 is made of the same corrosion-resistant material as the inner storage tank 13 and is welded and sealed to prevent cross-contamination of solutions. Each area can store sodium hydroxide solution of different concentrations to meet diverse production needs.

[0039] Refer to the instruction manual appendix Figures 5 to 7 The barrier assembly includes four hollow sockets 321 installed inside the lower half tank 1 and four interlocking rods 322 installed at the lower end of the inner storage tank 13, with the interlocking rods 322 inserted into the interior of the hollow sockets 321.

[0040] It should be noted that the hollow socket 321 is fixed to the inside of the lower half of the tank 1, while the plug rod 322 is welded to the lower end of the inner tank 13. This design not only provides mechanical support, but also ensures complete isolation between the inner tank and the outer shell, avoiding electrochemical corrosion. At the same time, the gap allows the leaked liquid to flow smoothly into the collection box 15 through the triangular guide plate 14.

[0041] Refer to the instruction manual appendix Figure 2 The lower tank 1 and the upper tank 12 are provided with fixing components. The fixing components are used to fix the lower tank 1 and the upper tank 12 together. The fixing components include two lower slot plates 411 installed at the upper end of the lower tank 1 and two upper slot plates 412 installed at the lower end of the upper tank 12. The lower slot plates 411 and the upper slot plates 412 are fixedly connected.

[0042] It should be noted that the lower perforated plate 411 and the upper perforated plate 412 are fixedly connected by bolts or pins to ensure that the upper half of the tank 12 and the lower half of the tank 1 are tightly closed to form a complete shell. The perforated design allows for quick assembly and disassembly, which facilitates regular inspection or replacement of the inner storage tank 13 without damaging the overall structure.

[0043] Working principle: Under normal storage conditions, sodium hydroxide solution is contained in the storage chamber 311 of the inner storage tank 13. The partition plate 312 inside the storage chamber 311 divides it into independent areas for storing solutions of different concentrations, preventing mixing. The solution is added through the inlet 211 at the upper end of the inner storage tank 13 and discharged through the drain valve pipe 212 at the lower end. A pressure gauge is installed on the pressure gauge mounting pipe 222 at the upper end of the inner storage tank 13 to monitor the internal pressure in real time. When the pressure exceeds the safety threshold, the pressure relief valve connected to the pressure relief valve connecting pipe 221 automatically opens to relieve pressure, ensuring operational safety. The inner storage tank 13 is inserted and fixed into four hollow sockets 321 on the inner side of the lower half tank 1 by four interlocking rods 322 at its lower end. This barrier component maintains a gap between the inner storage tank 13 and the lower half tank 1, avoiding direct contact, reducing possible electrochemical corrosion and leakage channels. The lower half tank 1 and... The upper tank 12 is connected and fixed by the lower perforated plate 411 and the upper perforated plate 412 of the fixing assembly, which together form the outer protective shell that encloses the inner tank 13. If the inner tank 13 ruptures due to corrosion or other reasons, causing sodium hydroxide solution to leak, the leaked solution will flow into the interlayer space formed by the inner tank 13, the lower tank 1, and the upper tank 12. The leaked liquid flows downward under the action of gravity and is guided by the triangular guide plate 14 installed on the inner side of the lower tank 1, and flows to the collection box 15 installed at the lower end of the lower tank 1. The operator can directly observe the presence of the leaked liquid and its liquid level through the strip observation window 16 on the surface of the collection box 15, so as to detect the leak in time. The collected leaked liquid can be safely discharged through the drain port 17 on the surface of the collection box 15 for treatment, preventing it from accumulating at the bottom of the tank and causing further corrosion or safety risks. This realizes the active collection, visual monitoring and safe disposal of the leaked liquid.

[0044] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
