Description

Technical Field

[0001] This invention relates to the field of pressure vessel technology, and in particular to a discharge port structure for a mother-daughter type pressure vessel and the mother-daughter type pressure vessel. Background Technology

[0002] A mother-daughter pressure vessel (or mother-daughter tank) is a structure in which multiple daughter vessels are located inside a single mother vessel. Currently, to allow independent unloading of each daughter vessel (inner vessel), each daughter vessel (outer vessel) requires an opening in the mother vessel (outer vessel) as its unloading port. This leads to a reduction in the sealing performance and pressure rating of the mother vessel. Solving these problems would require adding openings and reinforcement to the mother vessel or increasing its wall thickness, increasing production workload and equipment safety, and ultimately raising costs. Summary of the Invention

[0003] The purpose of this invention is to provide a discharge port structure for a mother-daughter pressure vessel and a mother-daughter pressure vessel including the discharge port structure, thereby reducing the number of openings on the mother vessel.

[0004] To achieve the above objectives, in a first aspect, the present invention provides a discharge port structure for a mother-daughter type pressure vessel, comprising:

[0005] The first connecting pipe that connects to the mother container;

[0006] A sealing cap is used to seal the first connector.

[0007] The first partition has a first through hole, and the first partition is disposed inside the first pipe and its outer peripheral side is sealed to the first pipe.

[0008] The second partition is disposed inside the first through hole, and there is a gap between its outer peripheral side and the wall of the first through hole;

[0009] The third partition has a second through hole and is detachably installed over the gap between the first and second partitions to seal the gap.

[0010] The second connector has one end connected to the corresponding sub-container, and the other end extends into the first connector after passing through the second partition and the second through-hole; and

[0011] A seal used to seal the second connector.

[0012] Optionally, the third partition is placed in close contact with the first and second partitions.

[0013] Optionally, the outer periphery of the first partition is welded to the first connecting pipe.

[0014] Optionally, the second pipe passes through the second partition and is welded to the second partition.

[0015] Optionally, the third partition is divided into multiple adjustment blocks in the circumferential direction, and each adjustment block is detachably fixed to the first partition and / or the second partition by screws.

[0016] Optionally, adjacent adjusting blocks are connected by a stop structure.

[0017] Optionally, the third partition is divided into three to five adjustment blocks in the circumferential direction.

[0018] Optionally, the seal is a KF flange.

[0019] Optionally, the end of the first connecting pipe facing away from the mother container is provided with a flange, the sealing cover is connected to the flange by bolts, and a sealing ring is also provided between the sealing cover and the flange.

[0020] In a second aspect, the present invention also provides a mother-daughter type pressure vessel, wherein the mother vessel contains one or more daughter vessels, and the mother vessel and daughter vessels adopt the discharge port structure of any of the mother-daughter type pressure vessels described in the first aspect above.

[0021] The above-mentioned technical solution of the present invention has the following advantages: The discharge port structure of the mother-daughter type pressure vessel provided by the present invention includes a first connecting pipe, a sealing cover, a first partition, a second partition, a third partition, a second connecting pipe, and a sealing element. One end of the first connecting pipe is installed in and communicates with the mother container. The sealing cover is detachably installed in the other end of the first connecting pipe. The first partition has a first through hole. The first partition is disposed within the first connecting pipe and its outer periphery is sealed to the first connecting pipe. The second partition is disposed within the first through hole, and there is a gap between the outer periphery of the second partition and the wall of the first through hole. The third partition has a second through hole, and the third partition is detachably installed over the gap between the first and second partitions to seal the gap. One end of the second connecting pipe communicates with the corresponding daughter container, and the other end passes through the second partition and the second through hole and extends into the first connecting pipe, where it is sealed by the sealing element. The discharge port structure of this mother-daughter pressure vessel allows each vessel to discharge independently while avoiding excessive openings on the mother vessel (multiple vessels share one opening on the mother vessel). This avoids the need to increase the wall thickness and reinforcement of the mother vessel due to multiple openings, ensuring the sealing and pressure rating of the mother vessel, improving equipment safety, and reducing costs.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0048] Embodiments of the present invention will now be described with reference to the accompanying drawings. Elements and features described in one drawing or embodiment of the invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that, for clarity, representations and descriptions of components or processes unrelated to the invention and known to those skilled in the art have been omitted from the drawings and description.

[0049] See Figures 1-3 as well as Figure 5 As shown, the discharge port structure 1 of the mother-daughter pressure vessel provided in this embodiment of the invention includes a first connecting pipe 11, a sealing cap 12, a first partition 13, a second partition 14, a third partition 16, a second connecting pipe 17, and a sealing element 18. One end of the first connecting pipe 11 is installed in and communicates with the mother container 2. The sealing cap 12 is detachably installed at the other end of the first connecting pipe 11 to seal the first connecting pipe 11, and is opened when a discharge operation is required.

[0050] See Figure 2 and Figure 3As shown, the first partition 13 has a first through hole. The first partition 13 is disposed within the first connecting pipe 11 and its outer periphery is sealed to the first connecting pipe 11. The second partition 14 is disposed within the first through hole. The size of the second partition 14 is smaller than the size of the first through hole, so that when the second partition 14 mates with the first partition 13, a gap 15 exists between the outer periphery of the second partition 14 and the wall of the first through hole, allowing the medium in the mother container 2 to pass through during unloading. The third partition 16 has a second through hole and is detachably fitted over the gap 15 between the first partition 13 and the second partition 14 to seal the gap 15.

[0051] One end of the second connector 17 is connected to the corresponding sub-container 3, and the other end passes through the second partition 14 and the second through hole and extends into the first connector 11. The end of the second connector 17 extending into the first connector 11 is sealed with a sealing element 18.

[0052] See Figure 6 As shown, when the mother container 2 needs to be unloaded, the sealing cover 12 and the third partition 16 are opened, and the medium inside the mother container 2 can be discharged through the gap 15 (see the dashed arrow at the gap 15). See also Figure 7 As shown, when sub-container 3 needs to unload, unloading can be achieved by opening the sealing cover 12 and the sealing element 18. This sub-container type pressure vessel's unloading port structure allows each container to unload individually while avoiding excessive openings on the main container (multiple containers sharing a single opening on the main container). This avoids the need to increase the wall thickness and reinforcement of the main container due to multiple openings, ensuring the sealing and pressure rating of the main container, improving equipment safety, and reducing costs.

[0053] To reduce the sealing difficulty at the unloading point of the mother container 2, a third partition 16 is detachably installed over the gap 15 between the first partition 13 and the second partition 14 to seal the gap 15. This can be achieved through the following specific embodiments. For some embodiments, see [link to specific embodiments]. Figure 2 and Figure 3As shown, the third partition 16 is in close contact with the first partition 13 and the second partition 14. More preferably, the sides of the first partition 13 and the second partition 14 facing the third partition 16 are flush, thus making the contact surface of the third partition 16 (facing the first partition 13 and the second partition 14) flat, simplifying the structure. Of course, in some other embodiments, the sides of the first partition 13 and the second partition 14 facing the third partition 16 are not flush; correspondingly, the contact surface of the third partition 16 is stepped, resulting in a better sealing effect. In some other embodiments, a sealing ring can also be provided on the contact surface between the third partition 16 and the first partition 13 and the second partition 14 to further improve the sealing effect. The third partition 16 is preferably detachably connected to the first partition 13 and the second partition 14 by screws. It should be noted that in some embodiments, the third partition 16 can be connected to only one of the first partition 13 or the second partition 14 by screws, or it can be connected to both the first partition 13 and the second partition 14 by screws simultaneously.

[0054] In this embodiment, the outer periphery of the first partition 13 and the first pipe 11 can be sealed by means of a tight fit, a sealing ring or other sealing structure or by welding.

[0055] In this embodiment, the second partition 14 is provided with a through hole for the second pipe 17 to pass through. Preferably, the second pipe 17 passes through the through hole and is welded and fixed to the second partition 14.

[0056] To facilitate adjustment of the discharge flow rate of the mother container 2, and to minimize the diameter of the first connecting pipe 11, in some embodiments, see [reference needed]. Figures 3-5 As shown, the third partition 16 is divided into multiple adjusting plates 161 in the circumferential direction, for example, two, three, four, five, six, seven, eight, etc. Each adjusting plate 161 is detachably fixed to the first partition 13 and / or the second partition 14 by screws. During unloading, the unloading flow rate is adjusted by removing only one or more adjusting plates 161. This structure can avoid the seal 18 by installing in sections, without increasing the diameter of the first connecting pipe 11 due to the need to avoid the seal 18 during overall installation.

[0057] In some preferred embodiments, see Figure 3 and Figure 5 As shown, adjacent adjusting block plates 161 are connected by a stop structure, forming a structure in which they act as pressure plates for each other, which is beneficial for sealing and installation positioning.

[0058] More preferably, the third partition 16 is divided into three to five adjustment blocks 161 in the circumferential direction, for example, three, four, or five.

[0059] In this embodiment, the seal 18 can be a conventional sealing structure combining a flange and a cover plate, or other conventional sealing structures. Preferably, a KF flange is used as the seal. It should be noted that the KF flange is an existing component and will not be described in detail here.

[0060] To facilitate the installation of the sealing cap 12, in some embodiments, a flange 111 is provided at the end of the first connecting pipe 11 facing away from the mother container 2, and the sealing cap 12 is connected to the flange 111 by bolts. To further improve the overall sealing, preferably, a sealing ring is also provided between the sealing cap 12 and the flange 111.

[0061] This embodiment also provides a mother-daughter type pressure vessel, see [link]. Figure 1 and Figure 2 As shown, the mother container 2 is provided with two sub-containers 3. Each of the two sub-containers 3 has a connected second pipe 17 that passes through the second partition 14 and the second through hole and extends into the first pipe 11. The specific discharge port structure has been fully described in the above embodiments and will not be repeated here.

[0062] In some other implementations, the parent container 2 may also contain one or more sub-containers 3, such as three, four, or five.

[0063] In summary, the discharge port structure of the mother-daughter pressure vessel of the present invention enables individual discharge of each container of the mother-daughter pressure vessel while avoiding excessive openings on the mother container (multiple containers sharing one opening on the mother container). This avoids the need to increase the wall thickness and reinforcement of the mother container due to multiple openings, ensuring the sealing and pressure rating of the mother container, improving equipment safety, and reducing costs.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that not every embodiment contains only one independent technical solution, and in the absence of conflict between solutions, the various technical features mentioned in each embodiment can be combined in any way to form other implementation methods that can be understood by those skilled in the art.

[0065] Furthermore, without departing from the scope of the present invention, modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some of the technical features, shall not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
