Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and in particular to a fastening adapter for a chemical storage tank. Background Technology

[0002] Chemicals such as formic acid, hydrazine hydrate, and aminoguanidine bicarbonate are stored in dry, cool warehouses in storage tanks. Large quantities are typically stored in ton containers, but for distribution, 100-200 liter containers are generally used. To facilitate filling by manufacturers, the inlet and outlet sizes of the storage tanks are usually customized according to the manufacturer's equipment. These sizes differ from the sizes of some major pipe fittings on the market, which is not conducive to their use.

[0003] The existing technical solutions have the following drawbacks: Because existing chemical storage tanks need to maintain a certain degree of airtightness, their inlet and outlet ports are generally of fixed size, which cannot be adapted to pipe joints of different sizes. Therefore, it is particularly important to design an adapter that is suitable for chemical storage tanks. Utility Model Content

[0004] The purpose of this invention is to provide a fastening adapter for chemical storage tanks to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A fastening adapter for a chemical storage tank includes a storage tank and an adapter. The storage tank has a through-hole at its top and a first cylindrical protrusion integrally formed with the storage tank at its top. The axis of the through-hole is collinear with the axis of the first cylindrical protrusion, and the top of the through-hole extends upward through the first cylindrical protrusion. The inner wall of the first cylindrical protrusion has a first threaded surface. The adapter has a cylindrical structure. One end of the adapter has a second threaded surface that matches the first threaded surface. The middle section of the outer side of the adapter has an annular portion integrally formed with the adapter. The outer periphery of the annular portion has a flange facing the second threaded surface. The top of the adapter has a third threaded surface, and the center of the top of the adapter has a through-hole.

[0006] By adopting the above technical solution, the first cylindrical protrusion integrally formed on the top of the liquid storage tank and the first threaded surface on its inner wall form an integrated tank structure during use. When in use, it is only necessary to insert the adapter into the inside of the first cylindrical protrusion to achieve the purpose of connecting the pipe using the third threaded surface at the top of the adapter. This allows pipe joints of different sizes to be adapted to the liquid storage tank through the adapter, avoiding the problem in the prior art where the inlet and outlet of the liquid storage tank are not threaded, resulting in the inability to adapt to multiple sizes of pipe joints.

[0007] In a further embodiment, the inner bottom of the first cylindrical protrusion is provided with a conical surface, and the top diameter of the conical surface is the same as the diameter of the circular hole, and the bottom diameter of the conical surface is the same as the diameter of the shaft hole.

[0008] By adopting the above technical solution, the bottom of the adapter can be configured to fit the conical surface, increasing the contact area between the top of the adapter and the inner bottom of the first cylindrical protrusion (if the conical surface is not provided, there will be no contact at the bottom), thus avoiding leakage caused by the liquid inside the storage tank directly impacting the mating gap between the first threaded surface and the second threaded surface.

[0009] In a further embodiment, a first sealing ring is fitted at the bottom end of the adapter, the first sealing ring being used to seal the gap between the bottom of the adapter and the inner bottom of the first cylindrical protrusion.

[0010] By adopting the above technical solution, the gap between the bottom of the adapter and the inner bottom of the first cylindrical protrusion is completely sealed by the first sealing ring.

[0011] In a further embodiment, a second cylindrical protrusion is provided at the top center of the adapter, and the top of the shaft hole extends upward to completely penetrate the second cylindrical protrusion, and a fourth threaded surface is provided at the outer bottom end of the second cylindrical protrusion.

[0012] By adopting the above technical solution, the major diameter of the third threaded surface is larger than that of the fourth threaded surface, thus enabling the connection of two different sizes of pipe fittings. If the size of the pipe fitting is compatible with the third threaded surface, it can be directly fitted onto the third threaded surface.

[0013] In a further embodiment, a locking nut is screwed to the top of the adapter, and a second sealing ring is provided between the bottom of the locking nut and the top of the annular portion.

[0014] By adopting the above technical solution, the second sealing ring enables the large-sized pipe joint to be sealed when connected to the round hole of the liquid storage tank through the adapter. Similarly, a similar locking nut structure can be set on the second cylindrical protrusion.

[0015] In a further embodiment, the outer wall of the annular portion is provided with anti-slip texture.

[0016] By adopting the above technical solution, force can be applied more effectively to firmly fix the adapter to the top of the liquid storage tank.

[0017] In summary, this utility model has the following beneficial effects: 1. By forming an integral cylindrical protrusion on the top of the liquid storage tank and the first threaded surface on its inner wall, an integrated tank structure is formed during use. When in use, simply insert the adapter into the interior of the first cylindrical protrusion to connect the pipe using the third threaded surface at the top of the adapter. This allows pipe fittings of different sizes to be adapted to the liquid storage tank through the adapter, avoiding the problem in the prior art where the inlet and outlet of the liquid storage tank are not threaded, resulting in the inability to adapt to multiple sizes of pipe fittings.
