Abstract

The application relates to the field of dangerous chemical storage equipment, and discloses an acrylic diluent anti-volatilization storage device, which comprises a tank body assembly and a tank cover assembly. The tank body assembly comprises a metal inner shell, a plastic outer shell, a metal supporting grounding column, a tank body liquid inlet and outlet and a tank body connecting fastening block. The tank cover assembly comprises a fixing column, an L-shaped fixing block, a piston sliding ring spring, a piston sliding ring and a tank cover connecting fastening convex. A vacuum cavity formed between the outer side of the metal inner shell and the inner side of the plastic outer shell can keep the temperature of the acrylic diluent in the metal inner shell stable, thereby reducing the influence of the temperature on the acrylic diluent. The metal inner shell, the metal supporting grounding column and the plastic outer shell can conduct internal static electricity and prevent external static electricity. When the acrylic diluent in the metal inner shell volatilizes and causes the internal pressure to increase, the acrylic diluent can be discharged to the outside, thereby preventing the acrylic diluent from volatilizing and causing the air pressure to increase and the storage device to explode.

Description

Technical Field

[0001] This application belongs to the technical field of hazardous chemical storage equipment, specifically an acrylic acid diluent anti-volatilization storage device. Background Technology

[0002] Acrylic thinner is an organic solvent widely used in coatings, adhesives, and printing inks. Its main components are acrylates and reactive diluent monomers. Due to its unsaturated double bond structure, it exhibits high volatility and chemical reactivity, and has a low flash point (≤23℃), classifying it as a Class III flammable liquid hazardous chemical under national regulations (hazardous chemical code 32198). During storage and use, it readily releases flammable vapors, posing not only a fire and explosion risk but also potential respiratory irritation and health hazards to operators. Therefore, developing an effective anti-volatile storage device is of great significance.

[0003] However, common storage devices for acrylic diluents often use iron drums. Although these can conduct internal static electricity to the ground, they are also easily affected by external static electricity. Furthermore, when the ambient temperature changes significantly, the acrylic diluent inside the iron drums is prone to evaporation, and the internal vapor pressure increases in high-temperature environments, which can easily lead to container deformation or seal failure. Utility Model Content

[0004] The purpose of this application is to provide an acrylic diluent anti-volatile storage device in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: An acrylic diluent anti-volatile storage device, comprising an anti-volatile storage device, the anti-volatile storage device comprising a tank assembly and a tank cover assembly, the tank assembly comprising a metal inner shell, a plastic outer shell, a metal support grounding post, a tank liquid inlet and outlet and a tank connecting fastening block, the tank cover assembly comprising a fixing post, an L-shaped fixing block, a piston sliding ring spring, a piston sliding ring and a tank cover connecting fastening protrusion.

[0006] By adopting the above technical solution, during the operation of the equipment, the vacuum cavity formed by the outer side of the metal inner shell and the inner side of the plastic outer shell can maintain the temperature stability of the acrylic diluent inside the metal inner shell, reducing the impact of temperature on the acrylic diluent and minimizing volatilization. The metal inner shell and metal support grounding post can transmit static electricity generated inside to the ground, while the plastic outer shell prevents external static electricity from causing sparks that could lead to liquid ignition and explosion.

[0007] When the acrylic diluent inside the metal inner shell evaporates, causing an increase in internal pressure, the piston sliding ring can be pushed upwards, allowing the horizontal vent to leak out. The internal pressure can be discharged to the outside through the horizontal and vertical vents, preventing the storage device from exploding due to the increased gas pressure caused by the evaporation of the acrylic diluent inside the metal inner shell.

[0008] In a preferred embodiment, a metal support grounding post is fixedly connected to the bottom of the metal inner shell, and the lower part of the metal support grounding post extends through the bottom of the plastic outer shell and is flush with the outer side of the bottom of the plastic outer shell.

[0009] By adopting the above technical solution, the static electricity generated by the internal acrylic diluent can be connected to the ground through the metal inner shell and the metal support grounding post, preventing the internal static electricity from causing the liquid to explode.

[0010] In a preferred embodiment, a liquid inlet / outlet of the tank is fixedly connected to the upper part of the inner metal shell, a tank connecting fastener is fixedly connected to the outer side of the liquid inlet / outlet, a plastic outer shell is fixedly connected to the lower part of the tank connecting fastener, the inner side of the plastic outer shell is wrapped with the inner metal shell, and the inner side of the plastic outer shell and the outer side of the inner metal shell form a vacuum cavity.

[0011] By adopting the above technical solution, the effect of temperature on acrylic diluent can be reduced through a vacuum chamber, thereby reducing the evaporation of the liquid.

[0012] In a preferred embodiment, a fixing post is fixedly connected to the lower part of the can lid assembly. A vertical air guide hole is vertically opened in the middle of the fixing post, and a horizontal air guide hole is horizontally opened below the fixing post. The horizontal air guide hole communicates with the fixing post.

[0013] By adopting the above technical solution, the internal pressure can be discharged to the outside through the horizontal and vertical air vents, which can prevent the acrylic diluent from evaporating inside the metal shell, causing the pressure to increase and potentially leading to an explosion of the storage device.

[0014] In a preferred embodiment, an L-shaped fixing block is fixedly connected to the outer side of the fixing post, a piston sliding ring spring is fixedly connected to the lower part of the inner top of the L-shaped fixing block, a piston sliding ring is fixedly connected to the lower part of the piston sliding ring spring, and a fixing post is slidably connected to the inner side of the piston sliding ring, covering the outer side of the horizontal air guide hole.

[0015] By adopting the above technical solution, when the internal air pressure is normal, the horizontal air guide hole can be covered by the piston sliding ring to prevent gas leakage.

[0016] In a preferred embodiment, a can lid connecting fastening protrusion is fixedly connected to the lower part of the can lid assembly, and a groove on the inner side of the can body connecting fastening block is slidably connected to the lower part of the can lid connecting fastening protrusion.

[0017] By adopting the above technical solution, the connection between the tank body assembly and the tank cover assembly can be kept firm, preventing the gas pressure from pushing the tank cover assembly out and causing liquid leakage.

[0018] In a preferred embodiment, a rubber sealing sliding ring is fixedly connected to the outer side of the L-shaped fixing block, and the rubber sealing sliding ring is slidably connected to the inner side of the liquid inlet and outlet of the tank. A rubber sealing compression ring is fixedly connected to the lower part of the tank cover assembly, and the rubber sealing compression ring is slidably connected to the top of the liquid inlet and outlet of the tank.

[0019] By adopting the above technical solution, the airtightness of the connection between the tank cover assembly and the tank body assembly can be guaranteed.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] During operation, the vacuum chamber formed by the outer side of the metal inner shell and the inner side of the plastic outer shell maintains a stable temperature for the acrylic diluent inside the metal inner shell, reducing the impact of temperature on the diluent and minimizing volatilization. The metal inner shell and metal support grounding post transmit static electricity generated inside to the ground, while the plastic outer shell prevents external static electricity from causing sparks that could ignite or explode the liquid.

[0022] When the acrylic diluent inside the metal inner shell evaporates, causing an increase in internal pressure, the piston sliding ring can be pushed upwards, allowing the horizontal vent to leak out. The internal pressure can be discharged to the outside through the horizontal and vertical vents, preventing the storage device from exploding due to the increased gas pressure caused by the evaporation of the acrylic diluent inside the metal inner shell.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example:

[0031] Reference Figure 1-5 An acrylic diluent anti-evaporation storage device includes an anti-evaporation storage device, which includes a tank assembly 1 and a tank cover assembly 2. The tank assembly 1 includes a metal inner shell 3, a plastic outer shell 4, a metal support grounding post 5, a tank liquid inlet and outlet 6, and a tank connection fastening block 7. The tank cover assembly 2 includes a fixing post 8, an L-shaped fixing block 12, a piston sliding ring spring 15, a piston sliding ring 13, and a tank cover connection fastening protrusion 9.

[0032] During operation, the vacuum cavity formed by the outer side of the metal inner shell 3 and the inner side of the plastic outer shell 4 maintains a stable temperature for the acrylic diluent inside the metal inner shell 3, reducing the impact of temperature on the acrylic diluent and minimizing volatilization. The metal inner shell 3 and the metal support grounding post 5 transmit static electricity generated inside to the ground, while the plastic outer shell 4 prevents external static electricity from causing sparks that could lead to liquid ignition and explosion.

[0033] When the acrylic diluent inside the metal inner shell 3 evaporates, causing the internal pressure to increase, the piston sliding ring 13 can be pushed upwards, allowing the horizontal vent hole 16 to leak out. The internal pressure can be discharged to the outside through the horizontal vent hole 16 and the vertical vent hole 14, which can prevent the acrylic diluent from evaporating inside the metal inner shell 3, causing the gas pressure to increase and the storage device to explode.

[0034] A metal support grounding post 5 is fixedly connected to the bottom of the inner metal shell 3. The lower part of the metal support grounding post 5 extends through the bottom of the plastic outer shell 4 and is flush with the outer bottom of the plastic outer shell 4. This allows static electricity generated by the internal acrylic thinner to be connected to the ground through the inner metal shell 3 and the metal support grounding post 5, preventing internal static electricity from causing the liquid to explode.

[0035] A liquid inlet / outlet 6 is fixedly connected to the upper part of the metal inner shell 3. A tank connecting fastener 7 is fixedly connected to the outer side of the liquid inlet / outlet 6. A plastic outer shell 4 is fixedly connected to the lower part of the tank connecting fastener 7. The metal inner shell 3 is wrapped inside the plastic outer shell 4. The inner side of the plastic outer shell 4 and the outer side of the metal inner shell 3 form a vacuum cavity. The vacuum cavity can reduce the influence of temperature on the acrylic diluent and reduce the evaporation of the liquid.

[0036] A fixing post 8 is fixedly connected to the lower part of the can lid assembly 2. A vertical vent hole 14 is vertically opened in the middle of the fixing post 8, and a horizontal vent hole 16 is horizontally opened below the fixing post 8. The horizontal vent hole 16 is connected to the fixing post 8. The internal pressure can be discharged to the outside through the horizontal vent hole 16 and the vertical vent hole 14, which can prevent the acrylic diluent from evaporating inside the metal inner shell 3, causing the pressure to increase and potentially leading to an explosion of the storage device.

[0037] An L-shaped fixing block 12 is fixedly connected to the outer side of the fixing post 8. A piston sliding ring spring 15 is fixedly connected to the lower part of the top inner side of the L-shaped fixing block 12. A piston sliding ring 13 is fixedly connected to the lower part of the piston sliding ring spring 15. The fixing post 8 is slidably connected to the inner side of the piston sliding ring 13 and covers the outer side of the horizontal air guide hole 16. When the internal air pressure is normal, the horizontal air guide hole 16 can be covered by the piston sliding ring 13 to prevent gas leakage.

[0038] A can lid connecting fastening protrusion 9 is fixedly connected to the lower part of the can lid assembly 2, and a groove on the inner side of the can body connecting fastening block 7 is slidably connected to the lower part of the can lid connecting fastening protrusion 9. This can keep the can body assembly 1 and the can lid assembly 2 firmly connected and prevent the gas pressure from pushing the can lid assembly 2 out, causing liquid leakage.

[0039] A rubber sealing sliding ring 11 is fixedly connected to the outer side of the L-shaped fixing block 12. The rubber sealing sliding ring 11 is slidably connected to the inner side of the liquid inlet / outlet 6 of the tank body. A rubber sealing compression ring 10 is fixedly connected to the bottom of the tank cover assembly 2. The rubber sealing compression ring 10 is slidably connected to the top of the liquid inlet / outlet 6 of the tank body. This ensures the airtightness of the connection between the tank cover assembly 2 and the tank body assembly 1.

[0040] The implementation principle of this embodiment of an acrylic diluent anti-evaporation storage device is as follows: During operation, the vacuum cavity formed by the outer side of the metal inner shell 3 and the inner side of the plastic outer shell 4 maintains a stable temperature for the acrylic diluent inside the metal inner shell 3, reducing the impact of temperature on the acrylic diluent and minimizing evaporation. The metal inner shell 3 and the metal support grounding post 5 transmit static electricity generated inside to the ground, while the plastic outer shell 4 prevents external static electricity from causing sparks that could lead to liquid ignition and explosion.

[0041] When the acrylic diluent inside the metal inner shell 3 evaporates, causing the internal pressure to increase, the piston sliding ring 13 can be pushed upwards, allowing the horizontal vent hole 16 to leak out. The internal pressure can be discharged to the outside through the horizontal vent hole 16 and the vertical vent hole 14, which can prevent the acrylic diluent from evaporating inside the metal inner shell 3, causing the gas pressure to increase and the storage device to explode.
