Description

[0002] Chemical storage tanks are containers used to store various chemicals, raw materials, products or by-products. They play an important role in the chemical production, processing and distribution processes. When storing some flammable substances, even a tiny spark may trigger an explosion or other situations. Therefore, removing static electricity is particularly important. Currently, the methods used to remove static electricity are to ensure that the storage tank and related equipment are well grounded so that static electricity can be safely discharged. A grounding device should be installed at the bottom of the storage tank to ensure that static electricity can be discharged through the grounding wire. An anti-static material is coated on the inner wall of the storage tank to reduce the generation and accumulation of static electricity.

[0036] Embodiment

[0037] As Figure 1 And Figure 2As shown in the figure, an anti-static structure for a flammable chemical storage tank proposed by the present utility model includes a storage tank 1, which is hollow and used for storage. An anti-static mechanism 2 installed on the storage tank 1, and the anti-static mechanism 2 is used to remove the static electricity contained in the air of the storage tank 1. The anti-static mechanism 2 includes a conductive rod 21 penetrating through the top of the storage tank 1. The conductive rod 21 is arranged in the shape of a regular quadrangular prism, so that the sliding sleeve 31 can drive the conductive rod 21 to rotate when rotating, and at the same time the conductive rod 21 can slide up and down in the sliding sleeve 31. The conductive rod 21 is grounded, and a conductive frame 22 is installed on the side of the conductive rod 21. Five groups of conductive sheets 23 are arranged in the conductive frame 22. The multiple groups of conductive sheets 23 are all fixedly connected to the conductive rod 21, and the conductive sheets 23 are grounded through the conductive rod 21, which is convenient for conducting the static electricity in the air and preventing static electricity from generating sparks.

[0038] Further, please refer to Figure 3 , the above anti-static structure includes a driving component 3 arranged on the top of the storage tank 1. The driving component 3 is used to drive the conductive rod 21 to rotate to improve the efficiency of removing static electricity in the air. The driving component 3 includes a sliding sleeve 31 sleeved on the conductive rod 21. Two groups of first bearings 32 are sleeved on the sliding sleeve 31. Fixed plates 33 are respectively arranged on the two groups of first bearings 32. Two connecting plates 34 are fixedly connected to both sides of the two fixed plates 33. The two connecting plates 34 are fixedly connected to the top of the storage tank 1. The positions of the fixed plates 33 and the connecting plates 34 are fixed, and the sliding sleeve 31 is kept rotating in place through the two groups of first bearings 32. One side of the conductive rod 21 is also provided with a motor bracket 35 installed on the top of the storage tank 1. A servo motor 36 is installed in the motor bracket 35. A first gear 37 is fixedly connected to the top of the servo motor 36. The servo motor 36 is used to drive the first gear 37 to rotate after starting. A second gear 38 meshing with the first gear 37 is arranged on the side of the first gear 37 close to the conductive rod 21. The second gear 38 is fixedly connected to the outer ring of the sliding sleeve 31. When the first gear 37 rotates, it drives the second gear 38 to rotate synchronously, thereby driving the sliding sleeve 31 to rotate, and further driving the conductive rod 21 to rotate, so that the conductive frame 22 and the conductive sheets 23 rotate synchronously and are in full contact with the air, so as to conduct the static electricity in the air.

[0039] Furthermore, as Figure 4 shown, the above anti-static structure further includes a sealing mechanism 4 installed on the top of the storage tank 1. The sealing mechanism 4 is used to ensure good sealing of the storage tank 1 when the conductive rod 21 moves. The sealing mechanism 4 includes a rubber sleeve 41 sleeved on the outside of the conductive rod 21. The rubber sleeve 41 is used to ensure the sealing performance when the conductive rod 21 slides. An installation sleeve 42 is arranged on the outside of the rubber sleeve 41, which is used to fix the position of the rubber sleeve 41. A second bearing 43 is installed on the outside of the installation sleeve 42. The second bearing 43 is installed on the top of the storage tank 1 to ensure the in-situ rotation of the installation sleeve 42.

[0040] Specifically, the above anti-static structure includes a lifting mechanism 5 for adjusting the height of the conductive frame 22. The lifting mechanism 5 includes a top plate 51 rotatably connected to the top of the conductive rod 21. The top plate 51 is fixed to the top of the storage tank 1 through a fixing frame, and the position of the top plate 51 is fixed. A threaded rod 52 is provided between the top plate 51 and the storage tank 1. Both ends of the threaded rod 52 are rotatably connected to a sliding plate 53. Two groups of limiting blocks 54 are slidably connected to both sides of the sliding plate 53. The sliding plate 53 moves smoothly under the limiting action of the limiting blocks 54, so that the movement of the threaded rod 52 is stable. The two upper limiting blocks 54 are fixedly connected to the bottom of the top plate 51, and the positions of the two upper limiting blocks 54 are fixed. The two lower limiting blocks 54 are fixedly connected to a mounting frame 55. The mounting frame 55 is mounted on the top of the storage tank 1, and the positions of the two lower limiting blocks 54 are fixed. A third gear 56 is fixedly connected to the threaded rod 52. The third gear 56 meshes with the second gear 38. When the second gear 38 rotates, it drives the third gear 56 to rotate synchronously, so that the threaded rod 52 rotates synchronously. A moving block 57 is threadedly connected to the threaded rod 52. When the threaded rod 52 rotates, it drives the sliding plate 53 to move up and down. A synchronous block 58 is slidably clamped on one side of the moving block 57 close to the conductive rod 21. When the moving block 57 and the synchronous block 58 move relative to each other, they move smoothly. At the same time, when the moving block 57 moves up and down, it drives the synchronous block 58 to move synchronously. One end of the synchronous block 58 away from the moving block 57 is fixedly connected to a rotating sleeve 59. The rotating sleeve 59 is rotatably connected to the outer circle of the conductive rod 21 and is used to drive the rotating sleeve 59 when the moving block 57 moves up and down, thereby driving the conductive rod 21 to move up and down, and the rotation of the conductive rod 21 does not affect the position of the rotating sleeve 59.

[0041] Finally, as Figure 5As shown in the figure, the above-mentioned anti-static structure further includes a cooperation adjustment component 6 installed on the lifting mechanism 5. The cooperation adjustment component 6 includes a push rod motor 61 installed on one side of the moving block 57. The output end of the push rod motor 61 is fixedly connected with a push plate 62. A sleeve 63 is arranged outside the push plate 62. The push plate 62 is slidably connected in the sleeve 63. The side of the sleeve 63 away from the push rod motor 61 is fixedly connected with a synchronous plate 64. The synchronous plate 64 is fixedly connected to the side of the synchronous block 58. After the push rod motor 61 extends, the moving block 57 and the synchronous block 58 are slightly separated, so that the third gear 56 and the second gear 38 are no longer in meshing rotation. Furthermore, the conductive rod 21 only rotates and its up and down positions are fixed. Similarly, when the push rod motor 61 contracts, the third gear 56 and the second gear 38 are meshed, and the conductive rod 21 moves up or down while rotating to adjust the height of the conductive frame 22 and the conductive sheet 23. The output end of the push rod motor 61 is slidably connected with the sleeve 63. A spring 65 is arranged in the sleeve 63. The spring 65 is sleeved on the outer ring of the output end of the push rod motor 61. As the second gear 38 rotates, the third gear 56 may not be in the meshing state when approaching the second gear 38, so that the spring 65 is compressed until the second gear 38 rotates to the position meshed with the third gear 56, and the spring 65 releases elastic force to make the third gear 56 and the second gear 38 meshed.

[0042] In this embodiment, first, the servo motor 36 is started. The servo motor 36 drives the first gear 37 to rotate and mesh with the second gear 38. At this time, the second gear 38 drives the sliding sleeve 31 to rotate. At the same time, the sliding sleeve 31 rotates smoothly under the limiting action of the two groups of first bearings 32. At this time, the conductive rod 21 rotates synchronously and drives the first bearing 32 and the fixing plate 33 to rotate. The fixing plate 33 is in contact with the air and conducts the static electricity in the air. At the same time, when the second gear 38 rotates, it drives the third gear 56 to rotate synchronously. Thus, the threaded rod 52 mainly drives the moving block 57 to move downward, so that the moving block 57 drives the rotating sleeve 59 to move downward synchronously, and the conductive rod 21 also moves downward. Moreover, the conductive rod 21 slides downward in the sliding sleeve 31 and drives the conductive frame 22 and the conductive sheet 23 to descend. At the same time, the servo motor 36 can also be started to rotate in the reverse direction and drive the static elimination mechanism 2 to move upward, so as to adjust the position and make full contact with the air to eliminate static electricity. After reaching the appropriate position, the push rod motor 61 is started to make the moving block 57 away from the synchronous block 58. At the same time, the third gear 56 is away from the second gear 38. Thus, when the conductive rod 21 rotates, it can not drive the threaded rod 52 to rotate, so that the conductive frame 22 and the conductive sheet 23 can rotate at a fixed height.

[0043] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
