Abstract
Description
Technical Field
[0001] This utility model relates to the field of water chestnut processing technology, specifically to a leak-proof organic chemical raw material storage device. Background Technology
[0002] Chemical engineering is an abbreviation for "chemical process," "chemical industry," and "chemical engineering." Any technology that uses chemical methods to change the composition or structure of substances or synthesize new substances falls under chemical production technology, also known as chemical process. The resulting products are called chemicals or chemical products. Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. Storage tanks are commonly used for storing them.
[0003] Utility model patent CN212952222U discloses a leak-proof chemical raw material storage tank, including an outer cylinder and support legs welded to its bottom. A first annular protrusion is welded to the upper end of the outer wall of the outer cylinder, and a second annular protrusion is welded to the lower end of the outer wall. Circular grooves are formed on the opposite surfaces of the first and second annular protrusions. Two slide rails are fixedly installed inside the circular grooves, and several movable plates are slidably connected between the two slide rails. Through the coordinated use of the first annular protrusion, protective sleeve, rotating shaft, second annular protrusion, circular grooves, slide rails, sliders, movable plates, wire mesh, and inner cylinder, when an object impacts the outer cylinder, it will contact the rotating shaft. Since the rotating shaft is rotatably installed, it can change the impact direction of the object, moving it to the side of the outer cylinder, preventing the object from hitting the outer cylinder directly and greatly reducing the impact force received by the outer cylinder.
[0004] However, existing chemical raw material storage tanks, while protected by a double structure of outer and inner cylinders, are only separated from the outer cylinder by wire mesh, lacking effective sealing components. When external impacts cause deformation of the outer cylinder, the inner cylinder may experience displacement, creating gaps and leading to leakage of chemical raw materials from the connection between the inner and outer cylinders. Furthermore, the interfaces between the inlet and outlet pipes and the inner cylinder are merely fixed connections, lacking flexible sealing design. Over time, these interfaces are prone to loosening due to vibration, increasing the risk of leakage. Utility Model Content

[0015] Beneficial effects
[0016] This invention provides a leak-proof storage device for organic chemical raw materials. Compared with the prior art, it has the following advantages:
[0017] 1. This leak-proof organic chemical raw material storage device forms an initial mechanical seal through the sealing plate on the lower surface of the cover and the sealing ring of the tank body convex plate. At the same time, the negative pressure suction mechanism drives the screw to pull the piston through the crank handle, reducing the air pressure inside the tank and making the cover and tank body fit tightly. The double sealing structure greatly reduces the leakage rate, avoids misalignment of the sealing surface, and ensures that the raw materials are leak-free.
[0018] 2. The leak-proof organic chemical raw material storage device has a top cover that is magnetically connected to the edge of the cover plate via a magnetic plate. The negative pressure suction mechanism is integrated into the upper surface of the cover plate. After the top cover is covered, it forms a protective barrier to prevent dust and liquid from entering. During maintenance, it is only necessary to open the top cover and rotate the limit knob to unlock the screw. After the piston is reset, the suction tank can be quickly disassembled for cleaning.

Detailed Implementation
[0025] 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.
[0026] Please see Figure 1-5 This utility model provides two technical solutions:
[0027] First embodiment: A leak-proof organic chemical raw material storage device includes a tank body 1, a cover plate 2 and a top cover 3. A first mating groove 11 is provided on the outer side of the opening of the tank body 1 for mating the connection of the cover plate 2. A protruding plate 12 is fixed on the inner side of the opening of the tank body 1. A sealing ring 13 made of fluororubber is bonded to the upper surface of the protruding plate 12.
[0028] Specifically, cover plate 2 is located on the top of tank body 1. Cover plate 2, together with protruding plate 12 inside tank body 1, is used to seal tank body 1. The upper surface of cover plate 2 is provided with a negative pressure suction mechanism to extract air from tank body 1 and connect cover plate 2 and tank body 1 under negative pressure. A sealing plate 21 is fixed on the lower surface of cover plate 2. The sealing plate 21, together with the sealing ring 13 on protruding plate 12, is used to seal cover plate 2 and tank body 1, forming an initial mechanical seal. Multiple equally spaced air extraction holes are opened at one end of the lower surface of cover plate 2. 22. A second mating groove 23 is provided on the upper surface edge of the cover plate 2 for fitting the top cover 3. The top cover 3 is set on the top of the cover plate 2 to hide and protect the negative pressure adsorption mechanism on the cover plate 2. A magnetic plate 31 is fixed on the lower inner wall of the top cover 3. The magnetic plate 31 is magnetically connected to the upper surface edge of the cover plate 2 to limit the position of the top cover 3 and the cover plate 2. The top cover 3 covers and protects components such as the suction tank 24 and the screw 29 to prevent external collisions or foreign objects from entering and to avoid the negative pressure suction mechanism from being exposed to the external environment.
[0029] The second embodiment differs from the first embodiment in that: a plurality of equally spaced suction canisters 24 are fixed to one end of the upper surface of the cover plate 2. The suction canisters 24 are connected to the suction holes 22 through pipes. A piston 25 is inserted inside the suction canister 24. A connecting plate 26 is fixed to one end of the piston 25. The connecting plate 26 is designed with an L-shaped structure. A plurality of equally spaced dovetail sliders 27 are fixed to the lower surface of the connecting plate 26. A plurality of dovetail grooves 28 adapted to the dovetail sliders 27 are opened in the middle of the upper surface of the cover plate 2. The slider 27 is located in the dovetail groove 28. A screw 29 is movably connected to the middle of one side of the connecting plate 26 via a bearing. A crank 210 is fixed to one end of the screw 29. A protrusion 211 is fixed to the other end of the upper surface of the cover plate 2. A screw groove 212 is provided on the protrusion 211. The screw 29 and the screw groove 212 are connected through internal and external threads. A screw hole 213 is provided at the top of the screw groove 212. A limit knob 214 is connected to the screw hole 213 through internal and external threads. The limit knob 214 corresponds to the screw 29 and is used to limit the screw 29.
[0030] When the device is in operation, the cover plate 2 is placed on the tank 1. The first mating groove 11 guides the cover plate 2 to be precisely aligned, avoiding sealing failure caused by installation misalignment. The sealing plate 21 and the sealing ring 13 on the protruding plate 12 cooperate to form an initial mechanical seal. Then, the crank handle 210 is turned to drive the screw 29 to rotate. The screw 29 engages with the threaded groove 212 of the protruding block 211 through internal and external threads, pulling the L-shaped connecting plate 26 to move along the dovetail slide 28, thereby driving the piston 25 to move from the bottom to the top of the suction tank 24, extracting air from the tank 1. When the piston 25 moves to the top of the suction tank 24, the air pressure inside the tank 1 drops, creating a negative pressure environment, causing the cover plate 2 to be attracted to the opening of the tank 1, further enhancing the sealing performance. After it is in place, the limit knob 214 is rotated to engage with the screw hole 213, locking the screw 29 to prevent loosening.
[0031] During pressure relief maintenance, rotate the limit knob 214 counterclockwise to loosen the screw 29, and slowly crank the handle 210 counterclockwise to reset the piston 25. After balancing the internal and external air pressure of the tank, remove the cover plate 2.
