Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a corrosion-resistant chemical liquid storage tank. Background Technology

[0002] Chemical liquid storage tanks are indispensable basic equipment in chemical production and storage processes, used to safely contain various liquid raw materials, intermediates, and finished products with corrosive, volatile, or specific chemical properties. To ensure production safety and product quality, storage tanks must undergo regular inspection, cleaning, and maintenance after a certain period of use or after changing the stored materials.

[0003] When performing internal maintenance, the first step is to open the storage lid located on top of the tank. However, in current technology, many chemical storage tanks, especially large and medium-sized ones, typically have storage lids that are quite large and heavy to ensure sealing and corrosion resistance. Currently, opening these lids mostly relies on manual operation. Operators need to manually lift the heavy lid and flip it to one side, which is not only physically demanding and inefficient, but also poses a significant safety hazard when the tank is high, as operators must climb to the top.

[0004] While some existing storage lids are equipped with simple hinges or auxiliary lever structures, this only slightly reduces the difficulty of opening and does not fundamentally solve the drawbacks of manual operation. Especially when the storage lid needs to be fully flipped open to provide unobstructed operating space, the bulky lid is difficult to control precisely during the flipping process, easily leading to shaking, collisions, or even accidental falling back. This could not only damage the tank equipment but also seriously threaten the personal safety of on-site operators. Therefore, existing technologies generally lack an effective solution that can be integrated into the storage tank to achieve automatic, smooth, and safe opening of the storage lid.

[0005] Therefore, this utility model proposes a corrosion-resistant chemical liquid storage tank to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a corrosion-resistant chemical liquid storage tank, aiming to improve the problems of existing corrosion-resistant chemical liquid storage tanks, such as bulky storage cover structure, reliance on manual opening, laborious operation, and safety hazards.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion-resistant chemical liquid storage tank, comprising: a base, a tank body, a storage port, a storage cover; and a support plate disposed on the upper edge of the tank body and a flipping assembly disposed on the support plate.

[0008] The flipping assembly includes a first motor mounted on the outer wall of the support plate, the output shaft of the first motor driving a rotating plate; the edge of the rotating plate is rotatably connected to the first end of a guide plate, and the second end of the guide plate is rotatably connected to a rotating shaft; the rotating shaft is fixed to the front of the flipping block.

[0009] The back of the flip block is slidably connected to the support plate, and one side of the flip block is connected to the edge of the storage cover through a connecting plate; a sliding column is also fixed on the back of the flip block, and the support plate has a vertical groove for the sliding column to slide and a deflection groove communicating with the upper end of the vertical groove.

[0010] Preferably, the corrosion-resistant chemical liquid storage tank further includes a protective component disposed inside the base; the protective component includes a second motor installed inside the base, a first rotating block that can rotate in the rotating groove and is driven by the second motor, a connecting column fixedly connected to the outside of the first rotating block, a second rotating block rotatably connected to the other end of the connecting column in the middle, and a collection groove rotatably connected to one end of the second rotating block.

[0011] Preferably, the rotating groove is formed on the inner wall of the base, and the first rotating block is embedded in the rotating groove.

[0012] Preferably, the second rotating block, driven by the connecting column, causes the collecting groove to extend out of the base along a preset trajectory.

[0013] Preferably, the outer surface of the support plate is provided with a guide rail, and the flipping block is connected to the support plate through a sliding engagement with the guide rail.

[0014] Preferably, when the flipping block slides upward along the vertical groove to the end of its stroke, the sliding column enters the deflection groove to guide the flipping block to perform a flipping motion.

[0015] Preferably, the first end of the connecting plate is hinged to the flipping block, and the second end of the connecting plate is hinged to the storage cover.

[0016] Preferably, the guide plate serves as a connecting rod, with its first end rotatably connected to the edge of the rotating plate and its second end rotatably connected to the rotating shaft.

[0017] This utility model has the following beneficial effects: 1. In this utility model, a flipping component driven by a first motor is first set up. This component, through the cooperation of a connecting rod and a slider mechanism, realizes a compound opening action of first lifting and then flipping the storage cover. This solves the problem that the storage cover of chemical storage tanks in the prior art usually needs to be opened manually, which is not only time-consuming, labor-intensive, and inefficient, but also poses certain safety hazards. It achieves the effect of automatic and smooth opening of the storage cover, greatly improving the convenience and safety of operation and reducing the intensity of manual labor.

[0018] 2. In this utility model, by setting a protective component driven by a second motor inside the base, the component drives the collection tank to automatically extend to directly below the storage port through a linkage mechanism, which solves the problem in the prior art that when adding chemical liquids into the storage tank, leakage or splashing is likely to occur, thereby polluting the equipment and the surrounding environment. It achieves the technical effect of effectively catching leaking liquids and preventing environmental pollution, and ensures the cleanliness and safety of the work site. Attached Figure Description

[0021] 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.

[0022] Reference Figures 1-6 The present invention provides an embodiment of a corrosion-resistant chemical liquid storage tank, which aims to solve the problems of easy leakage and environmental pollution during the filling of chemical liquids and the laborious and low degree of automation of opening the storage cover in the prior art.

[0023] The corrosion-resistant chemical liquid storage tank includes a base 3 and a tank body mounted on the base 3. The base 3 provides a stable mounting base for the entire device. A storage port 1 is provided at the center of the top of the tank body. A storage cover 2 for sealing the tank body is hinged to one side of the storage port 1.

[0024] To enable the automatic opening of the storage cover 2, a support plate 406 is fixedly connected to the upper edge of the tank body, and a flipping assembly 4 is provided on the support plate 406. The core driving component of the flipping assembly 4 is a first motor 401 installed on the outer wall of the support plate 406. The output shaft of the first motor 401 drives a rotating plate 402. The first end of a guide plate 403 is rotatably connected to the edge of the rotating plate 402, and the second end of the guide plate 403 is rotatably connected to a rotating shaft 404. The rotating shaft 404 is fixedly connected to the front of the flipping block 405, and the back of the flipping block 405 is slidably connected to the support plate 406. One side of the flipping block 405 is connected to the edge of the storage cover 2 through a connecting plate 408. In order to guide the flipping block 405 to achieve a compound motion of rising first and then flipping, a sliding column 407 is also fixedly connected to the back of the flipping block 405. Correspondingly, a vertical groove for the sliding column 407 to slide vertically and a deflection groove 409 communicating with the upper end of the vertical groove are provided inside the support plate 406.

[0025] To prevent leakage during liquid filling, a protective component 5 is installed inside the base 3. The power source of the protective component 5 is a second motor 506 installed inside the base 3. The output end of the second motor 506 drives and connects to a first rotating block 501. The first rotating block 501 is embedded in a rotating groove 503 opened on the inner wall of the base 3 and can rotate within the rotating groove 503. A connecting post 505 is fixedly connected to the outer side of the first rotating block 501. The other end of the connecting post 505 is rotatably connected to the middle of the second rotating block 502. One end of the second rotating block 502 is rotatably connected to a collection groove 504, and the other end of the second rotating block 502 is pivotally connected to the inner wall of the base 3.

[0026] After the first motor 401 starts, the power output of the first motor 401 drives the rotating plate 402 to rotate clockwise. The rotating plate 402 converts the rotational motion into an upward thrust through the guide plate 403 connected to it. This thrust acts on the rotating shaft 404. Since the rotating shaft 404 is fixed to the flipping block 405, the flipping block 405 slides upward on the support plate 406. The outer surface of the support plate 406 is provided with a guide rail. The flipping block 405 is stably connected to the support plate 406 through sliding cooperation with the guide rail. During the upward sliding of the flipping block 405, the sliding column 407 fixed to the back of the flipping block 405 slides upward synchronously in the vertical groove inside the support plate 406. The cooperation structure between the vertical groove and the sliding column 407 provides precise guidance for the initial vertical upward stage of the flipping block 405.

[0027] When the sliding column 407 slides upward in the vertical groove to the end of its stroke, the flipping block 405 cannot continue to rise vertically due to physical limitations. At this time, the torque continuously output by the first motor 401 will be converted into a force that pushes the flipping block 405 to flip outward through the rotating plate 402 and the guide plate 403. At the start of the flipping action, the sliding column 407 will smoothly enter the deflection groove 409 connected to the upper end of the vertical slide groove. The deflection groove 409 has a specific arc-shaped profile, and the movement trajectory of the sliding column 407 in the deflection groove 409 is strictly limited, thereby guiding the flipping block 405 to complete a smooth and precise flipping action. During the entire flipping process of the flipping block 405, the connecting plate 408 acts as a connecting rod. The first end of the connecting plate 408 is hinged to the flipping block 405, and the second end is hinged to the storage cover 2, thereby transmitting the flipping motion of the flipping block 405 to the storage cover 2, causing the storage cover 2 to flip outward synchronously and open.

[0028] After the second motor 506 is started, it drives the first rotating block 501 to rotate counterclockwise in the rotating groove 503 opened on the inner wall of the base 3. Since the connecting column 505 is fixedly connected to the first rotating block 501, the rotation of the first rotating block 501 will push the second rotating block 502 through the connecting column 505. The middle part of the second rotating block 502 is rotatably connected to the connecting column 505, one end is rotatably connected to the collection groove 504, and the other end is pivotally connected to the inner wall of the base 3. This connection method constitutes a set of ingenious linkage mechanisms. Under the push of the connecting column 505, the second rotating block 502 will drive the collection groove 504 to extend outward from the inside of the base 3 along a preset trajectory until it moves to the bottom of the storage port 1. This ensures that the collection groove 504 can achieve a large range of extension and positioning with a small driving stroke, and the structure is compact and the transmission is reliable.

[0029] The first end of the guide plate 403 is rotatably connected to the edge of the rotating plate 402, and the second end of the guide plate 403 is rotatably connected to the rotating shaft 404. Through this double rotational connection configuration, the single rotational motion of the rotating plate 402 can be effectively decomposed into the force that pushes the flipping block 405 to slide upward and the force that subsequently flips it.

[0030] The connecting plate 408 serves as the actuator for transmitting the flipping action. The first end of the connecting plate 408 is connected to the flipping block 405 by a hinge, and the second end of the connecting plate 408 is also connected to the storage cover 2 by a hinge. The double hinge structure ensures that when the flipping block 405 performs complex flipping movements, the storage cover 2 can be smoothly and synchronously lifted and flipped open without interference.

[0031] Working principle: Before storing the chemical liquid, the collection tank 504 is moved to the designated position by the protective component 5 fixed in the base 3 to prevent the chemical liquid from leaking and polluting the surrounding environment during the transfer of the chemical liquid. Then, the chemical liquid is stored in the device through the storage port 1. When the storage tank is full, the chemical liquid in the storage tank is cleaned. After the chemical liquid in the storage tank is cleaned, the storage cover 2 on the storage tank is opened by the flipping component 4 to clean the storage tank.

[0032] Before storing the chemical liquid, the second motor 506 fixed in the base 3 is started. After the second motor 506 is started, it acts on the first rotating block 501 rotatably connected in the rotating groove 503, causing the first rotating block 501 to rotate counterclockwise in the rotating groove 503. Since the connecting column 505 is fixedly connected to the first rotating block 501, when the first rotating block 501 rotates, it will push the second rotating block 502 rotatably connected to the connecting column 505 outward, causing the second rotating block 502 to rotate on the connecting column 505. When the second rotating block 502 is pushed, the collection tank 504 rotatably connected to the second rotating block 502 will be pushed outward together with the second rotating block 502, and the second rotating block 502 will rotate on the collection tank 504. When the collection tank 504 is pushed outward to the designated position, the second motor 506 in the base 3 is turned off, and then the chemical liquid is stored.

[0033] After the chemical liquid in the storage tank is cleaned out, the first motor 401 on the support plate 406 is started. The first motor 401 acts on the rotating plate 402, which is rotatably connected to the outer wall of the support plate 406, causing the rotating plate 402 to rotate clockwise on the outer wall of the support plate 406. When the rotating plate 402 rotates, it drives the guide plate 403, which is rotatably connected to the rotating plate 402, to move upwards. When the guide plate 403 moves upwards, it drives the rotating shaft 404, which is rotatably connected to the guide plate 403, to move upwards together with the guide plate 403. Since the rotating shaft 404 is fixed to the tilting block 405, when the rotating shaft 404 moves upwards, it drives the tilting block 405, which is slidably connected to the support plate 406, to slide upwards. The sliding column 407 is inside the support plate 406. When the flipping block 405 slides upward, the sliding column 407 slides upward inside the support plate 406. When the sliding column 407 slides upward to the designated position inside the support plate 406, the rotation of the rotating plate 402 will drive the guide plate 403 to rotate on the rotating plate 402 and the rotating shaft 404. After the guide plate 403 rotates, it will drive the rotating shaft 404 and the flipping block 405 to flip outside the support plate 406. The sliding column 407 on the flipping block 405 will enter the deflection groove 409 on the support plate 406 and move upward. When the flipping block 405 flips, it will drive the storage cover 2 to flip outward through the connecting plate 408. When the storage cover 2 flips to the designated position, the storage tank is cleaned.
