Description

Technical Field

[0001] This utility model relates to the field of chemical storage tank technology, specifically a protective chemical substance storage tank. Background Technology

[0002] The safe storage of chemical substances is a core guarantee in industrial production, scientific research experiments, pharmaceutical and chemical industries. In particular, strong acids, strong alkalis, flammable, explosive and toxic chemicals place extremely high demands on the protective performance of storage equipment. It is necessary to ensure that the items are not contaminated by the outside world and do not leak during storage, and can maintain their original properties for a long time. Currently, chemical storage tanks are generally used in the market, with the most common being a single tank structure.

[0003] Traditional single-layer sealed tanks have relatively simple sealing structures, typically relying on only one sealing cap or plug to achieve a seal. However, changes in the external environment and long-term corrosion of the seal by chemical substances can lead to seal failure, leakage, or contamination. To overcome these shortcomings, existing technology (Chinese patent application number 202420605084.0, application date 2024-03-26) discloses a sealed storage tank. This tank involves loading chemical substances into a second sealed tank, then aligning and rotating the sealing column and plug with the internal and external threads of both the first and second sealed tanks respectively. This allows the sealing plug and sealing column to fit tightly against both sealed container one and sealed container two, thus providing double-layer storage and double protection for chemical substances and preventing leakage. The rotating drive disc drives the drive rod to rotate, which in turn drives the gear to rotate, which in turn drives the two rack plates to move, so that the rack plates correspond one-to-one with the holes in the inner wall of sealed container one, preventing the internal and external threads of sealed container one and sealed container two from loosening due to long-term storage. However, in actual use, the design of the two-layer container will significantly increase the overall weight of the sealed container, making it inconvenient to move and transport, thus reducing its practicality.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a protective chemical substance storage tank that can effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a protective chemical substance storage tank to solve the problem that, in actual use, the design of the above-mentioned device in the background art leads to a significant increase in the overall weight of the sealed tank due to the two-layer tank design, which makes it inconvenient to move and transport, thereby reducing its practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a protective chemical substance storage tank, comprising a tank body, a tank lid covering the top of the tank body, an inner locking edge formed on the inner wall of the top of the tank lid near the edge, and the gap between the tank lid and the inner locking edge being adapted to the wall thickness of the tank body, and a sealing ring assembly fixedly provided on the inner wall of the top of the tank body, the sealing ring assembly having an L-shaped cross-section, and the inner locking edge being engaged between the L-shape and the inner wall of the tank body.

[0007] The top of the outer wall of the tank is formed with axially distributed positioning protrusions, and the bottom of the outer wall of the tank lid is provided with positioning grooves that correspond to and fit the positioning protrusions. The outer wall of the tank is also provided with a limiting component to fix each positioning protrusion within the corresponding positioning groove.

[0008] Preferably, the sealing ring assembly consists of an inner skeleton and an outer rubber ring. The inner skeleton is integrally formed on the inner wall of the tank, and the outer rubber ring is wrapped and bonded to the outer wall of the inner skeleton.

[0009] Preferably, the top of the can lid is fixedly connected to a handle so that the user can grip it or use equipment such as a crane to remove the can lid from the can body, and the positioning protrusion and the positioning groove are adapted to each other in an upper semi-circular structure.

[0010] Preferably, the limiting component includes snap-fit ​​plates corresponding to the bottom sides of each positioning groove, and each snap-fit ​​plate is provided with an insertion hole. A snap-fit ​​block is snapped into the inner side of the insertion hole, and the bottom end of all snap-fit ​​blocks is connected to a linkage ring. The linkage ring is rotatably disposed on the outside of the tank body, wherein the linkage ring adopts a hollow structure.

[0011] Preferably, the outer wall of the tank is integrally formed with a mounting base for supporting the linkage ring, and the top of the mounting base is also integrally formed with a limiting protrusion, which passes through the ring groove opened at the bottom of the linkage ring to the interior of the linkage ring for limiting sliding.

[0012] Preferably, the side wall of the linkage ring is fixedly connected with a push rod that facilitates the rotation of the linkage ring, and the push rod is fixed relative to the tank body by a reinforcing component.

[0013] Preferably, the reinforcing component includes a movable plate formed on the top of the push rod, and a fixed plate is fixedly connected between the mounting base and the outer wall of the tank, and the movable plate and the fixed plate are fixed through bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This protective chemical storage tank, through the snap-fit ​​of the inner locking edge and the sealing ring group, the positioning of the positioning protrusion and the positioning groove and the limiting component, makes the overall weight of this sealed tank significantly reduced compared with the two-layer tank design, so as to facilitate the handling and transportation, thereby improving the practicality of the device. At the same time, the above-mentioned components make the tank body and the tank cover tightly sealed, which can effectively prevent the leakage and splashing of dangerous chemical substances in the tank, thereby improving the safety protection during the storage process.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-3 The present invention provides the following technical solution: a protective chemical substance storage tank, including a tank body 1, a tank cover 2 is provided on the top of the tank body 1, an inner locking edge 3 is formed on the inner wall of the top of the tank cover 2 near the edge, and the gap between the tank cover 2 and the inner locking edge 3 is adapted to the wall thickness of the tank body 1, a sealing ring group 4 is fixedly provided on the inner wall of the top of the tank body 1, and the cross section of the sealing ring group 4 is an L-shaped structure, and the inner locking edge 3 is engaged between the L-shaped interior and the inner wall of the tank body 1.

[0022] Specifically, the sealing ring assembly 4 is composed of an inner skeleton 401 and an outer rubber ring 402. The inner skeleton 401 is integrally formed on the inner wall of the tank body 1, and the outer rubber ring 402 is wrapped and bonded to the outer wall of the inner skeleton 401. The inner skeleton 401 and the outer rubber ring 402 cooperate to form the sealing ring assembly 4, which can not only ensure the installation stability of the sealing ring assembly 4, but also ensure the deformation sealing effect of the inner locking edge 3 pressing the outer rubber ring 402.

[0023] Furthermore, the top of the outer wall of the tank body 1 is formed with axially distributed positioning protrusions 5, and the bottom of the outer wall of the tank cover 2 is provided with positioning grooves 6 that correspond to and are adapted to the positioning protrusions 5. The outer wall of the tank body 1 is also provided with a limiting component for fixing each positioning protrusion 5 within the corresponding positioning groove 6.

[0024] By engaging the inner locking edge 3 with the sealing ring group 4, and positioning the positioning protrusion 5 with the positioning groove 6, as well as limiting the positioning components, this sealed container significantly reduces its overall weight compared to a double-layer design, making it easier to move and transport, thereby improving the practicality of the device. At the same time, the above-mentioned components ensure a tight seal between the container body 1 and the container lid 2, effectively preventing the leakage and splashing of hazardous chemicals inside the container body 1, thereby improving safety during storage.

[0025] In addition, a handle is fixedly connected to the top of the lid 2 so that the user can grip it (for small sealed containers) or use equipment such as a crane (for large sealed containers) to remove the lid 2 from the container body 1. The positioning protrusion 5 and the positioning groove 6 are adapted to each other in the upper semi-circular structure so that when the lid 2 is closed, the positioning groove 6 and the positioning protrusion 5 can be smoothly positioned and engaged along the circular arc surface.

[0026] Example 2: Based on Example 1, please refer to... Figures 2-5 The limiting component includes snap-fit ​​plates 7 corresponding to the bottom sides of each positioning groove 6, and each snap-fit ​​plate 7 has an insertion hole 8. A snap-fit ​​block 9 is snapped into the inner side of the insertion hole 8, and the bottom ends of all snap-fit ​​blocks 9 are connected to a linkage ring 10. The linkage ring 10 is rotatably set on the outside of the tank body 1. The linkage ring 10 adopts a hollow structure to reduce the overall weight of the device, facilitate movement, and make it easy for the user to push the linkage ring 10 to rotate.

[0027] In use, the snap-fit ​​block 9 passes through the insertion hole 8 on the snap-fit ​​plate 7 to limit the positioning protrusion 5 to the inside of the positioning groove 6, so that the can lid 2 and the can body 1 can be snapped together. Then, the inner locking edge 3 is stably snapped into the inner side of the outer rubber ring 402 to achieve a tight sealing effect. Moreover, by simply rotating the linkage ring 10, all snap-fit ​​blocks 9 can be driven to rotate synchronously until they are dislodged from the insertion hole 8, so that the can lid 2 can be opened quickly.

[0028] In addition, the outer wall of the tank body 1 is integrally formed with a mounting seat 11 for supporting the linkage ring 10. The top of the mounting seat 11 is also integrally formed with a limiting protrusion 12. The limiting protrusion 12 passes through the ring groove opened at the bottom of the linkage ring 10 and slides into the interior of the linkage ring 10 to limit the translational direction of the linkage ring 10, thereby ensuring the stability of the relative sliding of the mounting seat 11 and the linkage ring 10.

[0029] Example 3: Based on Example 2, please refer to... Figure 1 , Figures 5-6 The side wall of the linkage ring 10 is fixedly connected with a push rod 13, which facilitates the rotation of the linkage ring 10, and the push rod 13 is fixed relative to the tank body 1 by a reinforcing component.

[0030] Furthermore, the reinforcing component includes a movable plate 14 formed on the top of the push rod 13, a fixed plate 15 fixedly connected between the mounting base 11 and the outer wall of the tank body 1, and the movable plate 14 and the fixed plate 15 are fixed through bolts 16.

[0031] In use, the moving plate 14 and the fixed plate 15 are relatively fixed by the fastening bolts 16, so that the push rod 13 is relatively fixed to the tank body 1, that is, the linkage ring 10 is axially fixed, thereby ensuring the stability of the insertion of the snap-fit ​​block 9 and the snap-fit ​​plate 7, and realizing the tight sealing of the tank body 1 and the tank cover 2. At the same time, simply unscrew the fastening bolts 16 to release the relative fixation of the moving plate 14 and the fixed plate 15, and you can grasp the tank body 1 to push the linkage ring 10 to rotate, thereby driving each set of snap-fit ​​blocks 9 to disengage from the snap-fit ​​plate 7, so as to open the tank cover 2.
