Description

Technical Field

[0001] The present application relates to the technical field of double-layer carbon source storage tanks, and in particular to an outlet waterproof structure of a double-layer carbon source storage tank made of stainless steel reinforced glass fiber. Background Art

[0002] As my country's safety and environmental awareness continues to strengthen, the safety of various chemical storage tanks has received increasing attention. If chemicals stored in chemical storage tanks leak, it will cause environmental pollution such as air, soil, and soil. In accordance with relevant regulations, most of the current double-layer carbon source storage tanks are relatively safer than single-layer storage tanks.

[0003] This type of double-layer storage tank is usually equipped with an outlet for inspection. However, the outlet structure of this type of storage tank is usually connected by two flanges abutting each other and sealed by a sealing ring between the two flanges. As the seal of the sealing ring ages or corrodes over a long period of use, the sealing effect is relatively poor, and there is a certain risk of water leakage during subsequent use, which affects the sealing and service life of the storage tank. Therefore, further improvement is needed. Utility Model Content

[0004] In order to improve the sealing effect at the outlet of the storage tank, the present application provides a stainless steel reinforced glass fiber double-layer carbon source storage tank outlet waterproof structure.

[0005] This application provides a stainless steel reinforced glass fiber double-layer carbon source storage tank outlet waterproof structure, which adopts the following technical solutions:

[0006] A stainless steel reinforced glass fiber double-layer carbon source storage tank outlet waterproof structure includes a tank body, a pipe fixedly penetrated through the outer peripheral wall of the tank body, and a sealing assembly arranged on the tank body to seal the opening of the pipe. The sealing assembly includes a cover plate covering the pipe opening and a mounting ring arranged on the lower surface of the cover plate, the lower surface of the cover plate abuts the upper surface of the pipe, the mounting ring is coaxially sleeved on the pipe, and the lower surface of the mounting ring is welded to the outer peripheral wall of the tank body.

[0007] By adopting the above technical solution, the cover plate is pressed against the upper surface of the pipe, and the mounting ring is welded to the outer wall of the tank body to reduce the possibility of foreign matter entering the pipe opening. Compared with the sealing ring in contact with the outside world, the sealing performance is improved, and it can also play a waterproof effect against external water.

[0008] Preferably, the tank body includes an inner tank and an outer tank from the inside to the outside, and a leakage detection line is wound between the inner tank and the outer tank. The leakage detection line is electrically connected to a liquid level sensor abutting the inner tank. The liquid level sensor is a non-contact liquid level sensor. The leakage detection line is fixedly passed through the mounting ring and extends outside the tank body.

[0009] By adopting the above technical solution, the pipeline can be used as a liquid leakage detection port to detect the leakage of the liquid stored in the inner tank.

[0010] Preferably, the cover plate is welded to the upper surface of the pipeline.

[0011] By adopting the above technical solution, the cover plate and the upper surface of the pipeline are welded to further improve the sealing effect of the pipeline and further reduce the possibility of foreign matter entering and passing through the pipeline.

[0012] Preferably, the outer tank protrudes and is fixed with a fixing ring welded to the inner peripheral wall or the outer peripheral wall of the mounting ring.

[0013] By adopting the above technical solution and providing a fixing ring, the welding area between the mounting ring and the outer tank is increased during the process of welding the mounting ring to the outer tank, thereby improving the sealing effect between the two, that is, improving the sealing effect at the pipeline opening.

[0014] Preferably, the cover plate is protrudingly provided with an abutment ring pressed against the inner circumferential wall of the pipe, and a sealing ring is provided between the abutment ring and the inner circumferential wall of the pipe.

[0015] By adopting the above technical solution, by providing an abutment ring and a sealing ring, the sealing ring is less likely to be exposed to the outside world and is less likely to age than a sealing ring provided between two flanges, thereby further improving the sealing effect of the pipeline; and for the cover plate that only abuts against the upper surface of the pipeline, since the two are rigidly connected, there may be some gaps, and when the leakage detection line is passed through the mounting ring, its sealing performance may be reduced, so the abutment ring and the sealing ring are used to improve the corresponding sealing effect.

[0016] Preferably, the cover plate is detachably connected to the mounting ring, and the sealing assembly further includes a flange coaxially sleeved on the outer peripheral wall of the mounting ring, a sealing member arranged on the upper surface of the flange, a pushing ring arranged on the lower surface of the cover plate to push the sealing member to move toward the mounting ring, and a connecting member connecting the cover plate and the flange, the sealing member is elastic and coaxially sleeved on the mounting ring; the outer peripheral wall of the sealing member is provided with a first inclined surface inclined toward the mounting ring, and the inner peripheral wall of the push ring is provided with a second inclined surface slidably connected to the first inclined surface.

[0017] By adopting the above technical solution, with the sliding connection between the first inclined surface and the second inclined surface, since the seal has elasticity, the seal is pushed against the outer peripheral wall of the mounting ring, and then the cover plate and the flange are connected through the connecting member, so as to seal the mounting ring and the cover plate. Compared with the sealing ring, the sealing effect is relatively good, and it is also relatively simple and convenient, thereby improving the sealing effect and the sealing efficiency.

[0018] Preferably, the seal abuts against the upper surface of the flange, the upper end surface of the flange has an abutment portion protruding along its radial direction, a number of the abutment portions are arranged at intervals along the axis of the mounting ring, and the lower surface of the seal is provided with a slot for the abutment portion to slide and insert.

[0019] By adopting the above technical solution, during the installation process, the seal is directly abutted between the flange and the cover plate. When the second inclined surface on the push ring slides and connects to the first inclined surface, relative rotation may occur between the seal, the cover plate, and the flange, which may affect the sealing effect of the seal on the installation ring. Therefore, a plurality of abutment portions are provided, which are inserted into slots provided in the seal to limit the rotation between the seal, the cover plate, and the flange, reduce the possibility of a gap between the seal and the installation ring, and also reduce the difficulty of operation, thereby indirectly improving the sealing effect of the installation ring.

[0020] Preferably, a sealing ring is provided on the inner peripheral wall of the sealing member in the middle, a mounting groove for mounting the sealing member is provided on the inner peripheral wall of the sealing member, and the sealing ring abuts against the outer peripheral wall of the mounting ring.

[0021] By adopting the above technical solution, a sealing ring is provided on the sealing member to further improve the sealing effect.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The cover plate is pressed against the upper surface of the pipe, and the mounting ring is welded to the outer wall of the tank body to reduce the possibility of foreign matter entering the pipe opening. Compared with the sealing ring in contact with the outside world, the sealing performance is improved, and it can also play a waterproof effect against external water.

[0024] 2. Weld the cover plate and the upper surface of the pipeline to further improve the sealing effect of the pipeline and further reduce the possibility of foreign matter entering the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-5 , further details of this application are given.

[0032] The embodiment of the present application discloses a stainless steel reinforced glass fiber double-layer carbon source storage tank outlet waterproof structure.

[0033] Example 1:

[0034] A stainless steel reinforced glass fiber double-layer carbon source storage tank outlet waterproof structure, refer to Figure 1 , comprising a tank body 1, a pipe 2 fixedly penetrated through the outer surface of the tank body 1, and a sealing assembly 3 arranged on the tank body 1 to seal the opening of the pipe 2.

[0035] In this embodiment, the tank body 1 includes, from the inside out, an inner tank 11 and an outer tank 12. Several pipes 2 are spaced apart along the length of the inner tank 11, specifically arranged as needed. The pipes 2 are fixedly inserted into the outer tank 12, and the pipes 2 serve as leakage detection pipes 2. In this embodiment, the sealing assembly 3 specifically includes a cover plate 31 that covers the opening of the pipe 2, and a mounting ring 32 disposed on the lower surface of the cover plate 31. The lower surface of the cover plate 31 abuts the upper surface of the pipe 2. In this embodiment, the cover plate 31 and the mounting ring 32 can be integrally formed, and the lower surface of the mounting ring 32 is welded to the outer peripheral wall of the outer tank 12 to seal the opening of the pipe 2.

[0036] Since the pipeline 2 serves as a pipeline 2 detection pipeline 2, specifically, a leakage detection line 4 is wound between the inner tank 11 and the outer tank 12, and the leakage detection line 4 is electrically connected to a liquid level sensor 41 abutting the inner tank 11. The liquid level sensor 41 is a non-contact liquid level sensor 41. The leakage detection line 4 is fixedly passed through the mounting ring 32 and extends to the outside of the tank body 1, and is electrically connected to a central control platform for performing data processing on the signal transmitted by the liquid level sensor 41.

[0037] Reference Figure 2 It should be noted that the cover plate 31 may be welded to the upper surface of the pipe 2 first, and then the mounting ring 32 may be welded to the lower surface of the cover plate 31, and finally welded to the outer wall of the outer tank 12. Compared with the integrally formed cover plate 31 and mounting ring 32, and the leakage detection line 4 is fixedly passed through the mounting ring 32, the sealing strength of the pipe 2 can be improved. However, the corresponding welding process required is more difficult and time-consuming, and can be selected according to needs.

[0038] The implementation principle of the waterproof structure of the outlet of a double-layer carbon source storage tank made of stainless steel reinforced glass fiber in the embodiment of the present application is: the cover plate 31 is pressed against the upper surface of the pipe 2, and the mounting ring 32 is welded to the outer wall of the tank body 1 to reduce the possibility of foreign matter entering the opening of the pipe 2. Compared with the sealing ring 61 in contact with the outside world, the sealing performance is increased, and it can also play a waterproof effect against external water.

[0039] Example 2:

[0040] Reference Figure 3 , which differs from Example 1 in that, because the cover plate 31 and mounting ring 32 are integrally formed, when the cover is closed over the opening of the pipe 2, a gap may remain between the mounting ring 32 and the outer can 12, affecting the corresponding welding effect. Alternatively, the mounting ring 32 may be too high, causing the cover plate 31 to not abut the opening of the pipe 2, affecting the corresponding sealing effect. Therefore, in this embodiment, a fixing ring 5 protrudes from the outer can 12 and is welded to the inner or outer circumferential wall of the mounting ring 32. This allows a gap between the height of the mounting ring 32 and the outer can 12. The provision of the fixing ring 5 further improves the welding effect between the mounting ring 32 and the outer can 12, thereby improving the corresponding sealing effect.

[0041] Example 3:

[0042] Reference Figure 4The difference from Example 1 is that, for the cover plate 31 that only abuts against the upper surface of the pipe 2, there may be some gaps between the two due to the rigid connection. When the leakage detection line 4 is passed through the mounting ring 32, its sealing performance may be reduced. Therefore, in this embodiment, the cover plate 31 is protruding and fixed with an abutment ring 6 that abuts against the inner circumferential wall of the pipe 2, and a sealing ring 61 is provided between the abutment ring 6 and the inner circumferential wall of the pipe 2 to improve the sealing effect between the cover plate 31 and the pipe 2.

[0043] Example 4:

[0044] Reference Figure 5 The difference from Example 1 is that the cover plate 31 is detachably connected to the mounting ring 32. In this embodiment, the sealing assembly 3 further includes a flange 33 coaxially sleeved on the outer peripheral wall of the mounting ring 32, a sealing member 34 provided on the upper surface of the flange 33, a pushing ring 35 provided on the lower surface of the cover plate 31 to push the sealing member 34 toward the mounting ring 32, and a connecting member 36 connecting the cover plate 31 and the flange 33.

[0045] In this embodiment, the seal 34 is elastic and is coaxially sleeved on the mounting ring 32. The outer peripheral wall of the seal 34 is provided with a first inclined surface 341 inclined toward the mounting ring 32, and the inner peripheral wall of the push ring 35 is provided with a second inclined surface 351 that is slidably connected to the first inclined surface 341.

[0046] In this embodiment, the seal 34 also abuts the upper surface of the flange 33. The upper end surface of the flange 33 has a radially protruding abutment portion 331. Several abutment portions 331 are spaced apart along the axis of the mounting ring 32. The lower surface of the seal 34 defines a slot 342 for the sliding insertion of the abutment portions 331. A sealing ring 61 is provided on the inner circumferential wall of the seal 34 at the center. The inner circumferential wall of the seal 34 defines a mounting groove for the seal 34. The sealing ring 61 abuts the outer circumferential wall of the mounting ring 32.

[0047] Among them, the push ring 35 and the cover plate 31 are integrally formed, and the connecting member 36 specifically includes a bolt 361 and a nut 362 threadedly connected to the bolt 361. The bolt 361 passes through the cover plate 31, the push ring 35, the flange 33 and is threadedly connected to the nut 362.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
