Description

TECHNICAL FIELD

[0001] The utility model relates to a vent structure technical field, concretely is a tank wall vent structure. BACKGROUND

[0002] The existing vent structure applied in the inner floating roof tank, the internal pressure of the floating roof tank changes when liquid is added or unloaded. The vent hole allows the gas in the tank to exchange with the outside, thereby maintaining the air pressure balance in the tank, preventing the tank body from deformation or distortion due to excessive pressure or too small pressure, but the existing vent structure has the problem that the protective net is easy to damage and inconvenient to replace.

[0003] Because the protective net is fixed by the clamping plate, when the internal pressure changes, external air enters or internal gas is pushed out, causing the protective net to deform. After multiple deformations, the clamping end of the protective net and the clamping plate will deform multiple times, and over time, the local deformation will reduce the strength of the protective net. If water is encountered, the problem of water corrosion may occur. When replacing, the bolts need to be removed first, and then replaced. The protective net in the existing vent structure is a single layer protective net. If the mesh density of the protective net is high, it cannot adapt to the rapid gas ejection caused by gas exchange due to pressure. If the mesh is large, it cannot effectively prevent the entry of external impurities.

[0004] Therefore, in order to effectively prevent external impurities from entering the tank and facilitate the replacement of the protective net, and secondly to improve the service life of the protective net, a tank wall vent structure is proposed to solve the above technical problems. SUMMARY

[0005] In view of the shortcomings of the prior art, the utility model provides a tank wall vent structure, which solves the problem that the existing vent structure in the inner floating roof tank cannot effectively prevent external impurities from entering, the protective net is difficult to replace, and the service life of the protective net cannot be improved.

[0006] To achieve the above object, the utility model provides the following technical scheme: a tank wall ventilation structure, including ventilation structure shell, install ventilation end mounting plate on ventilation structure shell outside end, be provided with ventilation structure of double -layer protection and convenient installation and dismounting on ventilation end mounting plate, its ventilation structure includes through -hole, square groove, first protective net, first clamping plate, first convex cylinder, second convex cylinder, second protective net, second clamping plate, its through -hole sets up on the surface of ventilation end mounting plate, still set up recess on the surface of ventilation end mounting plate, set up square groove in this recess, its recess covers first protective net, the first clamping plate is clamped on the surface of ventilation end mounting plate, the surface of first clamping plate sets up recess, is equipped with the first convex cylinder of first clamping plate surface through -hole, is equipped with the second convex cylinder of recess surface through -hole, its first convex cylinder inserts into through -hole, and second convex cylinder inserts into square groove, and first protective net is clamped between ventilation end mounting plate and first clamping plate, is equipped with second protective net on the recess of first clamping plate surface place, and is equipped with second clamping plate on the surface of first clamping plate, and second protective net is clamped between first clamping plate and second clamping plate.

[0007] Through the above technical scheme, further, the second convex cylinder is inserted into square groove through the mesh of first protective net.

[0008] Further, the mesh of the second protective net passes through the second convex cylinder.

[0009] As a preferred technical scheme, the thickness of the second protective net is less than the depth of the recess on the surface of the first clamping plate.

[0010] Further, the first clamping plate and the second clamping plate are spaced apart by a distance, which is greater than the thickness of the second protective net.

[0011] Compared with the prior art, the utility model provides a tank wall ventilation structure, which has the following beneficial effects:

[0012] 1. Through the improvement of the tank wall ventilation structure, specifically: through the superposition of the first protective net and the second protective net, and the first protective net and the second protective net are spaced apart by a certain distance, double protection is realized, and external impurities are effectively prevented from entering the tank; secondly, through the clamping relationship between the first clamping plate and the second clamping plate, and through the action of the first protruding cylinder and the second protruding cylinder, the protective net is clamped by the cylinder passing through the mesh hole of the protective net, and a certain movement space of the protective net can be realized, so that the protective net can adapt to the deformation of the protective net caused by the action of the tank pressure, so that the protective net and the clamping end are in a relatively tight clamping state, which can avoid the bending of the protective net at the clamping end, thereby improving the service life of the protective net; secondly, only through the plug-in clamping mode between the first clamping plate and the second clamping plate, the installation and disassembly of the protective net are convenient, therefore, through the arrangement of the above structures, the problems that the existing ventilation structure in the internal floating roof tank cannot effectively prevent external impurities from entering, the protective net is more troublesome to replace, and the service life of the protective net cannot be improved are solved.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] EMBODIMENT

[0025] Please refer to Figures 1-9 The present application provides the following technical solutions: a tank wall ventilation structure, comprising a ventilation structure shell 1, a ventilation end mounting plate 2 is mounted on the outside end of the ventilation structure shell 1, the ventilation end mounting plate 2 is provided with a double-layer protective ventilation structure which is convenient to install and disassemble, the ventilation structure comprises a through hole 3, a square groove 4, a first protective net 5, a first clamping plate 6, a first convex cylinder 7, a second convex cylinder 8, a second protective net 9, and a second clamping plate 10; the through hole 3 is formed on the surface of the ventilation end mounting plate 2, a groove is also formed on the surface of the ventilation end mounting plate 2, the square groove 4 is formed in the groove, the first protective net 5 is covered in the groove, the first clamping plate 6 is clamped on the surface of the ventilation end mounting plate 2, the groove is formed on the surface of the first clamping plate 6, the first convex cylinder 7 penetrating the first clamping plate 6 is arranged on the surface of the first clamping plate 6, the second convex cylinder 8 penetrating the groove is arranged on the surface of the groove, the first convex cylinder 7 is inserted into the through hole 3, and the second convex cylinder 8 is inserted into the square groove 4, the first protective net 5 is clamped between the ventilation end mounting plate 2 and the first clamping plate 6, the second protective net 9 is arranged on the groove on the surface of the first clamping plate 6, and the second clamping plate 10 is clamped on the surface of the first clamping plate 6, the second protective net 9 is clamped between the first clamping plate 6 and the second clamping plate 10.

[0026] In this implementation scheme, the specific working principle is as follows: As described above, when installing the first protective net 5 and the second protective net 9, simply place the first protective net 5 on the groove on the surface of the ventilation end mounting plate 2, then align the first protruding cylinder 7 on the first clamping plate 6 with the through hole 3, and then align the second protruding cylinder 8 with the square groove 4, and then press to clamp the first protective net 5. At this time, the second protruding cylinder 8 passes through the mesh of the first protective net 5, thus providing a certain amount of movement space for the first protective net 5. Then, place the second protective net 9 on the groove on the surface of the first clamping plate 6, and then clamp it through the second clamping plate 10. At this time, the second clamping plate 10 has symmetrical openings. Aligning the openings with the first protruding cylinder 7 and the second protruding cylinder 8 respectively will complete the clamping of the second protective net 9. At this time, the second protruding cylinder 8 also passes through the mesh of the first protective net 5. The mesh openings on the second protective net 9 allow for clamping, while also providing some room for movement. This completes the clamping of the first protective net 5 and the second protective net 9. The insert-type clamping facilitates the installation and removal of the protective nets. Furthermore, the increased space for movement extends the service life of the protective nets and prevents excessive clamping. When pressure changes within the tank cause rapid airflow, the clamping ends of the protective net and clamping plate can deform due to airflow, thus reducing the net's lifespan. Additionally, the double-layered protective net design improves the net's ability to intercept external impurities. Therefore, this solution addresses the problems of existing ventilation structures in internal floating roof tanks, which fail to effectively prevent the entry of external impurities, are cumbersome to replace, and cannot extend the lifespan of the protective nets.

[0027] In order to allow the first protective net 5 to have a certain amount of room to move and to prevent the service life of the first protective net 5 from being reduced due to excessive clamping, the second protruding cylinder 8 passes through the mesh of the first protective net 5 and is inserted into the square groove 4. It should be noted that the diameter of the second protruding cylinder 8 is smaller than the diameter of the mesh of the first protective net 5.

[0028] For details on the installation of the second protective net 9, please refer to [link / reference needed]. Figure 8 As can be seen, the mesh of the second protective net 9 passes through the second protruding cylinder 8, thus the second protective net 9 can be effectively supported by the action of the second protruding cylinder 8.

[0029] Secondly, it should be noted that the thickness of the second protective net 9 is less than the depth of the groove on the surface of the first clamping plate 6, which allows the second protective net 9 to have a certain amount of room to move.

[0030] Based on the above, it should also be noted that there is a distance between the first clamping plate 6 and the second clamping plate 10, which is greater than the thickness of the second protective net 9.

[0031] It should be pointed out finally that: the above only for the preferred embodiments of the utility model have, and do not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
