Description

Technical Field

[0001] This application relates to the field of compressed air storage tank technology, and in particular to a vertical air storage tank that is easy to integrate, expand, and transport in containers. Background Technology

[0002] In compressed air station systems, the air storage tank, as a critical pressure vessel, plays a vital role in stabilizing pressure, storing energy, and eliminating pulsations. With the acceleration of global industrialization, compressed air systems are developing towards modularization and integration, leading to a significant demand for compressed air storage tanks in international equipment procurement. However, the existing structural design of air storage tanks has significant shortcomings in meeting the demands of international transportation, resulting in high transportation costs and difficulty in improving loading and unloading efficiency. This contradiction is particularly prominent in ocean shipping scenarios.

[0003] Traditional compressed air storage tanks generally employ a three-legged support structure, with three independent legs evenly welded to the bottom of the tank at a 120° circumference. While this design meets the static stability requirements of the equipment and has a lower manufacturing cost, it exposes several problems under dynamic transportation conditions: Firstly, the lack of lateral connection between the independent legs prevents adjacent tanks from forming a mechanical interlock. According to containerized cargo securing standards, cylindrical pressure vessels must form an integral secured unit within a container. However, the discrete layout of traditional air storage tanks forces transporters to use custom-made wooden crates or steel frames for secondary securing, thereby increasing packing costs and reducing the container's capacity.

[0004] In terms of transport adaptability, the structural defects of traditional designs directly lead to low loading and unloading efficiency. The distribution of fulcrums in the three-legged support poses a dilemma for forklift operations: if the fork teeth are inserted through the gaps in the legs, the center of gravity of the tank may shift, easily causing a risk of tipping over; if a lifting method is used, additional lifting equipment is required and loading and unloading time is increased.

[0005] For example, the patent publication document with publication number CN215061246U discloses a vertical compressed air storage tank with liquid mist separation function, whose mounting support adopts the classic arrangement of three independent feet evenly distributed in a 120° circle.

[0006] Many existing technological improvements also have functional defects. For example, the patent publication document CN221943942U discloses a gas tank fixing base with good fixing effect. Although it provides effective external protection for a single vertical gas tank and solves the problem of the gas tank being easily damaged by external collisions during transportation, the gas tank fixing base with good fixing effect has a complex structure and its cost is higher than that of a custom wooden box. At the same time, although it takes into account the protection against collision damage, it does not take into account the issues of fixing in container transportation and the convenience of handling.

[0007] Therefore, there is an urgent need to propose new solutions for vertical gas storage tanks that facilitate container transportation and loading / unloading. Utility Model Content

[0008] The purpose of this application is to propose a vertical gas storage tank that is easy to integrate, expand, and transport in containers, thus solving the problem that traditional vertical gas storage tanks are inconvenient for container transportation and loading / unloading.

[0047] See Figure 1-10 This application discloses a vertical gas storage tank that is easy to integrate, expand, and transport in containers. Its advantages include convenient container transportation and loading / unloading, low packaging cost, high efficiency, and convenient operation.

[0048] In this embodiment, the vertical gas storage tank, which facilitates integration, expansion, and container transportation, includes a tank body 100 and a lower support body. The lower support body is disposed at the lower part of the tank body to support the tank body. The lower support body is provided with at least one set of first connecting holes 203, each set including two opposing first connecting holes 203, with the two first connecting holes 203 in each set located on opposite sides of the tank body. When multiple vertical gas storage tanks are connected sequentially, for example, when two vertical gas storage tanks that facilitate integration, expansion, and container transportation are placed close together, the two adjacent vertical gas storage tanks can be connected into one unit by aligning the first connecting holes 203 on the different vertical gas storage tanks and connecting them with connectors.

[0049] By installing a lower support on the tank body of this vertical gas storage tank, which is convenient for integration, expansion, and container transportation, when packaging for transport is required, the tank body can be simply wrapped with packing film to form independent protection. Then, the vertical gas storage tanks are grouped in pairs, with two of their first connecting holes facing each other. Connectors can then be installed to connect these two first connecting holes simultaneously, thus linking two adjacent vertical gas storage tanks into one unit. Furthermore, during loading, forklifts or spreaders can deliver two (or multiple tanks combined) into a container for loading or remove them from the container for unloading. Inside the container, because the vertical gas storage tanks are at least paired together and the spacing between adjacent tanks can be compact, they facilitate container transportation, offer good transport stability, and are easy to load and unload.

[0050] Furthermore, such as Figure 1 and 2 As shown, this vertical gas storage tank, which is convenient for integration, expansion, and container transportation, includes a tank body 100, and a first support 200 and a second support 300 disposed on the tank body 100. The lower support includes the first support 200 and the second support 300. The tank body 100 is a standard gas storage tank, comprising a tank body 101, which is vertically erected. A drain outlet 102 is provided at the bottom, a safety valve mounting port 103 is provided at the top, an air inlet 104 is provided on one side of its lower end, and an air outlet 105 is provided on the upper end of the side opposite to the air inlet 104. A pressure gauge mounting port 106 for detecting the internal compressed air pressure is also provided. Both the first support body 200 and the second support body 300 have a vertical positioning surface 202 and at least one first connecting hole 203 disposed on the positioning surface 202. The connecting hole penetrates the first support body 200 or the second support body 300. A forklift hole 204 is also disposed on the positioning surface 202. The first support body 200 and the second support body 300 are respectively disposed on both sides of the tank body 100, and the positioning surfaces 202 are arranged opposite each other. The upper parts of the first support body 200 and the second support body 300 are rigidly connected to the tank body 100, and the lower parts extend downward to below the bottom of the tank body 100 to form an upright support for the tank body 100. The forklift hole 204 on the first support body 200 and the forklift hole 204 on the second support body 300 are arranged opposite each other.

[0051] In this context, two pairs of opposite first connecting holes 203 on the first support body 200 and the second support body 300 form a group. Multiple groups of these first connecting holes 203 can be provided on the same lower support body; that is, multiple first connecting holes can be provided on each first support body 200 and the second support body 300. Generally, two pairs of coaxially opposite first connecting holes on the first support body 200 and the second support body 300 are considered as a group.

[0052] The connector can be understood as a screw and nut assembly.

[0053] This vertical gas storage tank, designed for easy integration, expansion, and container transport, has a tank body 100 equipped with a first support 200 and a second support 300 for upright support. When packaging for transport is required, the tank body 100 can be simply wrapped with packing film to provide independent protection. Then, the vertical gas storage tanks are grouped in pairs, with two positioning surfaces 202 (not specified on the first or second support 300) of the two tanks facing each other, and the first connecting holes 203 on the two positioning surfaces 202 aligned. Screws are then inserted through the two aligned first connecting holes 203 and secured together with nuts to firmly connect the vertical gas storage tanks. Furthermore, during loading, a forklift can directly insert into the forklift hole 204 to simultaneously load both tanks into a container or remove them from the container for unloading. Vertical gas storage tanks, which are easy to integrate and expand within containers and are suitable for container transport, are connected in pairs, and the spacing between adjacent tanks can be compact. Therefore, they are easy to transport, have good transport stability, and are convenient to load and unload.

[0054] In order to facilitate pairwise connections, such as Figure 4 As shown, each positioning surface 202 is provided with two first connecting holes 203, such as... Figure 1 and Figure 2 As shown, the two first connecting holes 203 are symmetrically arranged about the central axis of the tank body 100.

[0055] It is worth noting that during loading, the vertical gas tanks, which are convenient for integration, expansion, and container transportation, are connected in pairs as a group because the forklift arm length is suitable for lifting two at a time. With special adjustments to the forklift arm, three or more can be lifted in each group.

[0056] In the embodiments of this disclosure, such as Figure 1 and Figure 3As shown, a first connecting ear 400 is provided on each side of the top of the tank body 100. A third connecting hole 401 is provided on the first connecting ear 400. The connecting line of the two first connecting ears 400 is perpendicular to the connecting line of the first support body 200 and the second support body 300. When loading into a container, two vertical gas storage tanks, which are designed for easy integration and container transport, are placed in the container with their orientation parallel to the length of the container. This avoids the risk of the gas storage tanks tilting and squeezing the container doors along the length of the container. Since the container is originally closed in the width direction, the adjacent vertical gas storage tanks can provide support and offset the risk of swaying. After the first connecting lug 400 is installed, the two adjacent first connecting lugs 400 can be fixed together in the width direction of the container by inserting screws into the third connecting holes 401 and using nuts. This further makes the placement of the vertical gas storage tanks more stable and eliminates the risk of them squeezing each other in the width direction of the container.

[0057] In this embodiment of the disclosure, the vertical gas storage tanks, which are arranged in pairs for easy integration, expansion, and container transportation, are originally connected only by screws on the first support body 200 or the second support body 300. Further, as... Figure 2-3 As shown, a second connecting lug 500 is provided on each side of the top of the tank body 100. Each second connecting lug 500 has a fourth connecting hole 501. The connecting line between the two second connecting lugs 500 is parallel to the connecting line between the first support body 200 and the second support body 300. Based on this, the two vertical gas storage tanks, which are designed for easy integration, expansion, and container transport, can be connected by screws and nuts in the fourth connecting holes 501, thus sharing the connection stress between the first support body 200 and the second support body 300 and making the connection more stable.

[0058] It is worth noting that if there is a gap between two adjacent first connecting ears 400 or second connecting ears 500 during operation, a shim can be placed to fill the gap. However, the gap can also be ignored because the force is not large, and a screw and nut can be used to establish the connection.

[0059] In some implementations, such as Figure 2 As shown, lifting eye holes 600 can also be provided on the first connecting ear 400 and the second connecting ear 500. If a lifting operation is required, a hook can be used to hook onto the lifting eye hole 600 for lifting.

[0060] In this embodiment, the distance D between the positioning surface 202 and the central axis of the tank 100 is greater than the outer circumferential radius R of the tank 100. Thus, when two vertical gas storage tanks that are easy to integrate, expand and transport in containers are connected and combined, there will be a slight gap between their tank bodies 101. With the wrapping of the packing film, the appearance of the tank body 101 will not be scratched during transportation.

[0061] In some embodiments, the air inlet 104 is located on the side of the tank body 101 where the first support 200 is located, and the air outlet 105 is located on the side of the tank body 101 where the second support 300 is located. Neither the air inlet 104 nor the air outlet 105 protrudes from the vertical plane where the positioning surface 202 is located, and the outer end face of the pressure gauge mounting port 106 does not protrude from the outer surface of the tank body 101. Thus, after this vertical gas storage tank product, which is convenient for integration, expansion, and container transportation, is loaded into a container, there is no risk of damage to the appearance of adjacent tank bodies 100 due to the protrusion of the air inlet 104, air outlet 105, and pressure gauge mounting port 106.

[0062] In the embodiments of this disclosure, such as Figure 4 As shown, both the first support 200 and the second support 300 include a first plate 201, one side of which is a positioning surface 202. Second plates 206 protruding away from the positioning surface 202 are provided on both sides of the first plate 201 in the vertical direction. The first support 200 and the second support 300 are manufactured by bending the plates, achieving a lightweight design. The bending design of the second plates 206 enhances the structural stability of the first plate 201 and ensures the structural strength of both the first support 200 and the second support 300. Both the first support 200 and the second support 300 can be connected to the tank 100 by welding. During connection, the central axis of the first plate 201 is tangent to the outer side of the tank body 101 and a weld is applied. Then, the side of the second plate 206 away from the first plate 201 contacts the outer side of the tank body 101 and a weld is applied.

[0063] Furthermore, the bottom surfaces of the first support body 200 and the second support body 300 are both horizontally provided with support plates 207 for support. The length direction of the support plates 207 is perpendicular to the connection line between the first support body 200 and the second support body 300. That is, the support plates 207 are connected to the bottom of the first plate body 201 and the second plate body 206 and are welded to the first plate body 201 and the second plate body 206 as a whole. This not only enhances the structural stability of the first support body 200 and the second support body 300, but also reduces the pressure of the first support body 200 and the second support body 300 on the support surface (ground), thus protecting the support surface.

[0064] Furthermore, a reinforcing rib 210 can be provided in the middle of the first plate 201 to connect with the support plate 207 to further enhance the stability of the structure. To reduce weight, weight-reducing holes 205 can be provided on the first plate 201.

[0065] Furthermore, the support plate 207 is provided with a second connecting hole 209, which can be fixed by passing an expansion screw through the first connecting block during installation, or by connecting and fixing it with other installation devices by bolts.

[0066] Furthermore, to facilitate operation and enhance connection stability, the support plate 207 extends directly outwards to both ends, forming a third connecting ear 208 on the outer side of the second plate 206. The second connecting hole 209 is provided on the third connecting ear 208, which reduces operational interference when applying bolts or nuts for fixing, making operation more flexible.

[0067] In this embodiment of the present disclosure, each positioning surface 202 is provided with two forklift holes 204. The forklift holes 204 are rectangular. When the forklift picks up the vertical gas storage tank which is convenient for integration, expansion and container transportation, the forklift arm can be directly inserted into the forklift hole 204. Furthermore, the two forklift holes 204 are symmetrically arranged with respect to the central axis of the tank body 100 so that the tank body 100 is more stable during the handling process after picking up the forklift. Moreover, the forklift holes 204 are set at a position lower than the bottom of the tank body 100 so that the forklift arm will not interfere with the tank body 100 during operation.

[0068] In some implementations, such as Figure 5 and Figure 6As shown, the air inlet 104 is located on the side of the tank body 101 and extends into the tank body 101 in a manner that is tangential to the inner wall of the tank body 101 in the direction of air intake. A guide ring 107 is coaxially arranged inside the tank body 101. The lower side of the guide ring 107 extends below the horizontal position of the air inlet 104, and the upper side extends above the horizontal position of the air inlet 104. An annular sealing plate 108 is provided on the guide ring 107. The inner side of the sealing plate 108 is connected to the upper edge of the guide ring 107, and the outer side of the sealing plate 108 is connected to the inner wall of the tank body 101. The guide ring 107 and the sealing plate 108 together form a downward-opening guide channel 109 on the inner wall of the tank body 101. Compressed air enters the guide channel 109 from the intake direction. Under the constraint of the guide channel 109, the compressed air forms a high-speed airflow that rapidly surrounds the guide channel 109, resulting in centrifugal flow. This causes oil mist and moisture in the compressed air to be separated. During the centrifugal process, the guide channel 109 can guide and constrain the newly entered compressed air, preventing it from rapidly diffusing inside the tank body 101 and losing its rotational flow speed, thus reducing the effectiveness of removing oil mist and moisture. At the same time, the contact between the inner wall of the tank body 101 and the sealing plate 108, guide ring 107, etc., and the high-speed compressed air flow will have a viscous effect on oil mist and moisture, and has a large contact area, ensuring the ability to dehydrate and remove oil. The separated oil mist and moisture converge downwards to the bottom of the tank body 101, and can then be discharged from the drain port 102 at the bottom.

[0069] Furthermore, such as Figure 5 and Figure 6 As shown, the guide ring 107 is also provided with an inwardly extending annular baffle plate 110, and the air outlet 105 is located above the sealing plate 108, so that the compressed air entering the tank 100 must pass through the inner hole of the baffle plate 110 before entering the air outlet 105. First, the baffle plate 110 can prevent the moisture or oil mist that has separated from the tank from being carried to the air outlet 105 by the upward compressed air; second, the baffle plate 110 can prevent the moisture or oil mist that has separated from the tank from flowing upward and forming a convergence on the baffle plate 110, which plays a role in accelerating the condensation and fall of the moisture and oil in the compressed air to the bottom of the tank 100 (tank body 101).

[0070] In the embodiments of this disclosure, such as Figure 7 and Figure 8As shown, the tank 100 includes a tank body 101, on which an air outlet 105 and an air inlet 104 are provided. The air outlet 105 is positioned higher than the air inlet 104. A guide ring 107 is coaxially arranged inside the tank body 101, and there is a gap between the tank body 101 and the guide ring, which serves as a guide channel. The air inlet 104 connects to the guide channel. An annular sealing plate 108 is provided on the upper side of the guide channel. The inner side of the sealing plate 108 is connected to the upper edge of the guide ring 107, and the outer side is connected to the inner wall of the tank body 101. The difference from the previous embodiment is that the air inlet 104 can extend radially along the tank body 101 and connect to the guide channel.

[0071] Similarly, compressed air enters the guide channel from the air inlet 104 and impacts the guide ring 107 at high speed. Under the guidance of the guide ring 107, the compressed air undergoes high-speed centrifugal flow in the guide channel. In addition, the guide ring 107 and the inner wall of the tank body 101 have a viscous effect on the oil mist and moisture in the compressed air, causing the oil mist and moisture in the compressed air to be separated. During the centrifugal process, the guide channel 109 simultaneously plays a guiding and constraining role on the newly entered compressed air, preventing the compressed air from rapidly diffusing inside the tank body 101 and losing the speed of rotational flow, thus reducing the effect of removing oil mist and moisture.

[0072] Furthermore, such as Figure 7 and Figure 8 As shown, in the above configuration, compressed air enters through the inlet 104 and impacts the guide ring 107 head-on. While this impact accelerates the separation of water and oil, it also causes the air to flow rapidly downwards towards the bottom of the tank body 101 under the guidance of the guide ring 107. Therefore, a C-shaped baffle 111 is provided on the lower side of the guide channel. The C-shaped baffle 111 is located below the inlet 104. The inner side of the C-shaped baffle 111 is connected to the lower edge of the guide ring 107, and the outer side is connected to the inner wall of the tank body 101. The ends of the C-shaped baffle 111 form the flow opening 114 of the guide channel. By blocking the lower side of the guide channel 109 with the C-shaped baffle 111, the compressed air is prevented from flowing directly downwards and is forced to undergo centrifugal motion along the guide channel 109 before entering the tank body 101 through the flow opening 114.

[0073] In the embodiments of this disclosure, such as Figure 1 and Figure 7As shown, a drain outlet 102 is provided at the bottom of the tank 100, and a drain valve 113 can also be installed at the drain outlet 102. Further, a liquid level observation hole 115 is provided at the lower end of the tank, the observation hole being higher than the bottom of the tank, and a transparent observation window 116 is provided on the liquid level observation hole 115. Further, a liquid level sensor 117 is provided on the tank, used to detect the liquid level inside the tank. When a certain amount of liquid (separated water or oil, etc.) accumulates in the tank 100, it can be observed through the observation window 116. Simultaneously, when the liquid accumulates to a certain amount, it can be detected and identified by the liquid level sensor 117, providing a further reminder to promptly drain the liquid from the tank 100. Liquid drainage can be performed using the drain valve 113.

[0074] In addition, compressed air has a wide range of applications. In actual applications, the demand for compressed air is relatively large, or the demand fluctuates greatly. For example, the instantaneous air consumption of air-using equipment or processes is much greater than the average air supply of the compressor, or there are periodic, high peak air demand (e.g., multiple pneumatic tools start at the same time, large cylinders move, sandblasting, pulse backflushing, etc.).

[0075] Generally, a single gas storage tank has a diameter of about 300-500mm. For transportation considerations, such as accommodating the height of containers, the height is typically around 2000-2500mm, or even smaller. The capacity of a single gas storage tank is limited, and for safety reasons, a single tank should not be too large. Multiple tanks can be connected in parallel to provide a larger total volume to absorb peak demands, preventing sudden drops in system pressure and ensuring stable operation of downstream equipment. Firstly, it stabilizes system pressure. A larger total gas storage volume can more effectively smooth pressure fluctuations caused by compressor start-ups and shutdowns, valve openings and closings, etc., maintaining the system pressure within a narrower and more stable range. This is crucial for applications such as precision pneumatic equipment, spraying, and purging. Secondly, it reduces the frequency of compressor start-ups and shutdowns. When gas consumption varies significantly, a single small gas storage tank may cause the compressor to start and stop frequently to meet changing demands. Connecting a larger total volume in parallel can extend the compressor's operating time and reduce the number of start-ups and shutdowns, thereby significantly reducing energy consumption (due to higher starting current) and extending compressor life.

[0076] Based on this, such as Figure 9 and Figure 10As shown, the vertical gas storage tank of this application, which facilitates integration, expansion, and container transportation, has a lower support body on its tank body. During integrated expansion, multiple vertical gas storage tanks are arranged side-by-side in pairs according to the required capacity. Two first connection holes of two adjacent vertical gas storage tanks are brought close together in a facing manner. Connectors can then be installed to connect these two first connection holes simultaneously, thus connecting the two adjacent vertical gas storage tanks into one unit. Then, an integrated inlet connecting pipe connects the air inlets on each tank in parallel, and an integrated outlet connecting pipe connects the air outlets on each tank in parallel. Compressed air produced by the gas generating equipment is introduced into the tank through the integrated inlet connecting pipe and stored. Gas-using equipment can access the gas by connecting to the integrated outlet connecting pipe, thereby achieving expansion and capacity increase.

[0077] Furthermore, such as Figure 9 and Figure 10 As shown, to facilitate the connection of the exhaust and inlet integrated connecting pipes during expansion, the tank body 100 includes a tank body 101. The tank body 101 is provided with an exhaust port 105 and an inlet port 104, both of which are equipped with connecting flanges 112. Therefore, by correspondingly installing flanges on the exhaust or inlet integrated connecting pipes, the flanges can be quickly installed and connected to the connecting flanges 112 using screws. Generally, for ease of installation during expansion, the axis of the inlet port 104 is parallel to the exhaust port 105 and perpendicular to the connection line of the two first connecting holes 203 in a set.

[0078] Furthermore, the vertical gas storage tank of this application, which is easy to integrate, expand, and transport in containers, can also be used to optimize spatial layout or meet spatial constraints. For example, sometimes installing a single gas storage tank with an ultra-large volume is not feasible due to space constraints (such as height limitations or doorway size). In this case, connecting multiple smaller-volume gas storage tanks in parallel can more flexibly adapt to the existing spatial layout. As another example, in large factories or long-distance pipeline networks, it may be necessary to set up gas storage tank groups (local buffers) in different areas or near major gas consumption points. Connecting these regional gas storage tanks in parallel can optimize the pressure distribution and response speed of the entire pipeline network.

[0079] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
