Abstract
Description
Technical Field
[0001] This utility model relates to the field of organic solvent storage container technology, specifically to a storage tank for organic solvents. Background Technology
[0002] Organic solvents are a class of organic compounds that can dissolve substances insoluble in water, such as oils, waxes, and resins. They are mostly liquid at room temperature and are either volatile (e.g., ethanol, acetone) or non-volatile (e.g., mineral oil). As key basic materials in industrial production, scientific research and other fields, the storage safety and stability of organic solvents directly affect production efficiency, experimental accuracy and personnel safety. Storing organic solvents in storage containers can achieve safe, stable and long-term storage of solvents.
[0003] Existing storage containers use a single container that can only store a single solvent. They lack precise labeling and corresponding structures, making it easy for operators to make mistakes in taking out the solvent due to misidentification. This poses a significant risk, especially in laboratory settings where multiple solvents are stored and industrial settings involve multiple batches of solvents being handled.
[0004] For example, the organic solvent preservation and protection device disclosed in patent CN223356347U includes a storage tank with a protective outer cover threaded onto the top of the tank and a sealing inner cover slidably installed inside the protective outer cover. In this patent, the storage structure is a single integrated tank, which can only hold a single type or a single batch of organic solvent. It cannot achieve physical isolation storage of multiple solvents in the same device. Furthermore, the feeding structure of this device does not have a filter component, so impurities during solvent feeding cannot be intercepted at the inlet. After directly entering the storage cavity, they are prone to reacting with the solvent or precipitating, affecting the stability of the solvent.
[0005] Therefore, it is necessary to invent a storage container for organic solvents to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a storage tank for organic solvents, which solves the problems of the above-mentioned technologies that can only hold a single type or batch of organic solvents, cannot achieve physical isolation storage of multiple solvents in the same device, and do not have a filter component, so impurities during solvent feeding cannot be intercepted at the inlet and directly enter the storage chamber, which are prone to reacting or precipitating with the solvent, affecting the stability of the solvent.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a storage container for organic solvents, comprising a support frame and four storage containers. The support frame is vertically spaced with two support plates. The top openings of the four storage containers are sealed with sealing caps by multiple bolts. A feed pipe is fixedly inserted vertically through the center of the top surface of the sealing cap. A twist-lock sealing cap is fitted to the top of the feed pipe. A filter assembly is removably assembled inside the feed pipe. The filter assembly includes a first filter screen, a second filter screen, and a filter frame for supporting the first and second filter screens. A label frame is fixed to the front outer wall of the middle part of the support frame, and the position of the label frame corresponds one-to-one with the front of the four storage containers for placing labels indicating the type and concentration of organic solvents in the storage containers.
[0008] Preferably, the four storage tanks are arranged in an array and fixed between two support plates.
[0009] Preferably, the bottom end of the feed pipe extends into the internal cavity of the storage tank after passing through the sealed tank cover.
[0010] Preferably, the outer wall ring of the feed pipe is provided with external threads, and the inner wall ring of the twist lock sealing cover is provided with internal threads that match the external threads.
[0011] Preferably, each of the storage tanks has a conical material-gathering structure integrally formed at its bottom end, and a discharge pipe is fixedly connected to the discharge port at the bottom end of the conical material-gathering structure in the vertical direction. The discharge pipe is connected to the internal cavity of the storage tank, and a discharge valve is installed in series in the middle section of the discharge pipe.
[0012] Preferably, filter screen one and filter screen two are arranged at intervals in the vertical direction, with filter screen one located directly above filter screen two. Filter screen one and filter screen two have different mesh counts, forming a graded filtration structure, and the pore size of filter screen one is larger than that of filter screen two.
[0013] Preferably, the filter frame is fixedly connected to the edges of filter screen one and filter screen two respectively, and handles are symmetrically fixed on the left and right sides of the top of filter screen two.
[0014] Preferably, the outer walls of both filter screen one and filter screen two are evenly spaced with six sliders along the circumferential direction. The inner wall of the feed pipe is axially provided with a groove that matches the slider at the position of each slider. The slider can be slidably embedded in the groove to realize the sliding assembly and positioning of the filter assembly and the feed pipe.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model achieves safe and separate storage of different types of organic solvents through a separate array structure of four storage tanks, effectively avoiding the risks of mixed storage and confusion in retrieval. In addition, the label frame on the front of the storage tank allows operators to quickly identify the type and concentration of the solvent in the tank, avoiding errors in retrieval. It is especially suitable for scenarios where multiple solvents are stored in the laboratory or multiple batches of solvents are turned over in industrial production, significantly improving the safety and efficiency of storage management. 2. This utility model assembles a pull-out filter assembly inside the feed pipe. During feeding, larger impurities in the solvent (such as solid particles mixed in the raw material or foreign matter remaining in the storage container) can be intercepted first through filter screen one, and smaller impurities can be filtered through filter screen two. This prevents impurities from entering the storage tank with the solvent and affecting the purity. It achieves real-time graded filtration during liquid feeding and reduces the difficulty of cleaning and maintaining the filter assembly through the pull-out structure, thus balancing filtration effect and practicality.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0019] This utility model provides, for example Figures 1-5The diagram shows a storage container for organic solvents, comprising a support frame 1 and four storage tanks 3. The support frame 1 is vertically spaced with two support plates 2. The top openings of the four storage tanks 3 are sealed with sealing caps 4 by multiple bolts. A feed pipe 5 is fixedly inserted vertically through the center of the top surface of the sealing cap 4. A twist-lock sealing cap 6 is fitted to the top of the feed pipe 5. The outer wall of the feed pipe 5 is provided with external threads 501, and the inner wall of the twist-lock sealing cap 6 is provided with internal threads 601 that match the external threads 501. A label frame 10 is fixed to the front outer wall of the middle part of the support frame 1, and the position of the label frame 10 corresponds one-to-one with the front of the four storage tanks 3, for placing labels indicating the type and concentration of organic solvents in the storage tanks 3.
[0020] In this embodiment, the support frame 1 and the support plate 2 form a stable frame structure, providing reliable support and fixation for the four storage tanks 3. This ensures that the storage tanks 3 remain stable during storage and will not shift or tip over due to shaking or external forces, thus guaranteeing storage safety. The four storage tanks 3 enable the safe and separate storage of different types of organic solvents. Furthermore, the label frame 10 facilitates the placement of labels indicating the type and concentration of organic solvents in the storage tanks 3, allowing staff to quickly identify and distinguish the solvents in different tanks, improving work efficiency, and preventing safety accidents caused by misuse of solvents. Four storage tanks 3 are arranged in an array and fixed between two support plates 2. The bottom end of the feed pipe 5 passes through the sealed tank cover 4 and extends into the internal cavity of the storage tank 3. Each storage tank 3 has a conical material gathering structure integrally formed at its bottom end. The discharge port at the bottom end of the conical material gathering structure is fixedly connected to a discharge pipe 7 in the vertical direction. The discharge pipe 7 is connected to the internal cavity of the storage tank 3. A discharge valve 8 is installed in series in the middle section of the discharge pipe 7.
[0021] In this embodiment, the feed pipe 5 can accurately guide the organic solvent into the storage tank 3, and the conical material gathering structure at the bottom of the storage tank 3 can concentrate the solvent in the tank to the outlet, so that the solvent can be discharged smoothly through the discharge pipe 7. The discharge valve 8 can precisely control the discharge flow rate and speed of the solvent, and flexibly adjust the discharge amount according to actual needs to meet the requirements of different production or use scenarios.
[0022] The feed pipe 5 has a retractable filter assembly 9 inside. The filter assembly 9 includes a first filter screen 901, a second filter screen 902, and a filter frame for supporting the first filter screen 901 and the second filter screen 902. The first filter screen 901 and the second filter screen 902 are arranged vertically at intervals, with the first filter screen 901 located directly above the second filter screen 902. The first filter screen 901 and the second filter screen 902 have different mesh counts, forming a graded filtration structure. The pore size of the first filter screen 901 is larger than that of the second filter screen 902. The filter frame is connected to the filter screen 902. The edges of screen 1 (901) and screen 2 (902) are fixedly connected. Handles 903 are symmetrically fixed on the left and right sides of the top of screen 2 (902). Six sliders 904 are evenly spaced along the circumference on the outer walls of screen 1 (901) and screen 2 (902). The inner wall of the feed pipe 5 is axially provided with a groove 905 that matches the position of each slider 904. The slider 904 can slide into the groove 905 to realize the sliding assembly and positioning of the filter assembly 9 and the feed pipe 7.
[0023] In this embodiment, filter screen 901 and filter screen 902 form a graded filtration structure. Filter screen 901 has a larger pore size, which can first filter out larger impurity particles in the organic solvent; filter screen 902 has a smaller pore size, which can further filter out smaller impurities, ensuring the purity of the solvent entering the storage tank 3 and improving the solvent quality. Furthermore, the sliding assembly and positioning of the filter component 9 and the feed pipe 5 are realized through the sliding cooperation of the slider 904 and the slide groove 905. The installation and disassembly process is simple and quick. The handle 903 is designed to facilitate operation by the staff, and the filter component 9 can be easily pulled out for cleaning or replacement, ensuring that the filtration effect is always in good condition.
[0024] Working principle of this utility model: Refer to the instruction manual appendix Figures 1-5 When using this utility model, firstly, the four sealing caps 4 are tightly sealed to the top opening of the corresponding storage tank 3 with multiple bolts. Then, the sealing caps 4 are screwed open, and different types of organic solvents are slowly injected into the corresponding storage tank 3 through the feed pipe 5. When injecting organic solvents, the solvents can be filtered in stages through the filter screen 901 and filter screen 902 inside the feed pipe 5, making the solvents entering the storage tank 3 purer. After the injection is completed, the twist lock sealing cap 6 is tightened again. Select the label corresponding to the type and concentration of organic solvent in each storage tank 3 from the prepared labels, and place it in the label frame 10 at the corresponding position on the front outer wall of the middle of the support frame 1 to ensure that the label is clearly visible and easy for staff to identify. When cleaning the filter assembly 9 is required, rotate the twist-lock sealing cap 6 at the top of its feed pipe 5 to remove the twist-lock sealing cap 6 from the feed pipe 5. Hold the handle 903 with both hands and slowly and evenly pull the filter assembly 9 upward along the axial direction of the feed pipe 5. After the filter assembly 9 is completely pulled out of the feed pipe 5, it can be cleaned and maintained. Then, hold the handle 903 on the clean and dry filter assembly 9 with both hands, align the slider 904 of the filter assembly 9 with the groove 905 on the inner wall of the feed pipe 5, and slowly and evenly push it downward into the feed pipe 5 along the groove 905 until the filter assembly 9 is fully installed.
