Description

Technical Field

[0001] The present disclosure relates to the technical field of liquid storage and transportation, and in particular to a liquefied gas container. Background Art

[0002] When a liquefied gas container is filled, overflow is required after the liquid level reaches the effective volume. The overflow situation is used to determine whether filling needs to be stopped. In the prior art, a fullness measuring tube is generally preset at the effective volume liquid level height, and the position of the tube mouth is flush with the effective volume liquid level. When the liquid is filled to the effective volume liquid level height, the liquid will overflow the container from the fullness measuring pipe. This structure has liquid level fluctuations during filling, and liquid will flow out of the overflow pipe before the liquid level reaches the effective volume liquid level height, so it is impossible to accurately determine whether the container is filled to the effective volume, resulting in the container not being filled to the effective volume or excessive liquefied gas overflowing from the container, causing waste. Summary of the invention

[0003] One purpose of the present disclosure is to solve the technical problem in the prior art that it is impossible to accurately determine whether a container is filled to an effective volume through an overflow pipe.

[0004] In order to solve the above technical problems, the present disclosure adopts the following technical solutions:

[0005] According to one aspect of the present disclosure, the present disclosure provides a liquefied gas container, comprising: a tank body, a fullness measuring tube and a liquid collecting piece; the fullness measuring tube is penetrated through the tank body, and has a fullness measuring liquid inlet section extending vertically inside the tank body; the liquid collecting piece is sleeved on the fullness measuring liquid inlet section; a liquid collecting cavity is formed inside the liquid collecting piece, and the bottom of the liquid collecting cavity is lower than the fullness measuring liquid inlet section; the liquid collecting piece is provided with a fullness measuring liquid inlet port communicating with the interior of the tank body, the bottom of the fullness measuring liquid inlet port is flush with the effective volume liquid level of the liquefied gas container and higher than the pipe mouth of the fullness measuring liquid inlet section; the liquid collecting cavity is connected with the interior of the tank body through the fullness measuring liquid inlet port, and the minimum flow area of ​​the connecting channel is greater than the flow area of ​​the fullness measuring liquid inlet section.

[0006] It can be seen from the above technical solutions that the present disclosure has at least the following advantages and positive effects:

[0007] In the present disclosure, a liquid collecting piece is sleeved on the full liquid inlet section of the full measuring tube, and a liquid collecting cavity is formed inside the liquid collecting piece, and the bottom of the liquid collecting cavity is lower than the full liquid inlet section of the full measuring tube. At the same time, a full liquid inlet is also provided on the liquid collecting piece, and the full liquid inlet connects the liquid collecting cavity with the interior of the tank body, and the bottom of the liquid collecting cavity is flush with the effective volume liquid level of the liquefied gas container and is higher than the liquid inlet end of the full measuring tube. During the filling process, the liquid collecting piece will block most of the waves. When the liquid is filled to a height close to the effective volume liquid level, part of the liquid will pass over the full liquid inlet and enter the liquid collecting cavity. Since the space of the liquid collecting cavity is relatively small compared to the tank body, no large waves can be formed, and the bottom of the liquid collecting cavity is lower than the full liquid inlet section of the full measuring tube, the liquid in the liquid collecting cavity cannot enter the full measuring tube at this time. When the liquid is filled to the effective volume level, the liquid flows into the liquid collecting chamber in large quantities over the full liquid inlet, so that the liquid in the liquid collecting chamber rises above the pipe opening of the full liquid inlet section, and the liquid flows out through the full pipe, indicating that the liquid has been filled to the effective volume level. This solves the technical problem in the prior art that it is impossible to accurately determine whether the container is filled to the effective volume through the overflow pipe.

[0028] Although the present disclosure can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the present disclosure and is not intended to limit the present disclosure to that described herein.

[0029] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present disclosure, rather than implying that each embodiment of the present disclosure must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0030] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the present disclosure are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indications of these directions also change accordingly.

[0031] In conjunction with the drawings of this specification, some embodiments of the present disclosure are further described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] The present disclosure provides a liquefied gas container, see Figure 1 The liquefied gas container comprises a tank body 10, a fullness measuring tube 20 and a liquid collecting member 30. The fullness measuring tube 20 is arranged on the tank body 10 to connect the inside of the tank body 10 with the outside of the tank body, and comprises a fullness measuring liquid inlet section 21 located inside the tank body 10, and the fullness measuring liquid inlet section 21 is a section of pipe extending vertically. The liquid collecting member 30 is sleeved on the fullness measuring liquid inlet section 21.

[0033] It can be understood that the pipe opening of the above-mentioned full liquid inlet section 21 can be arranged upward or downward, and the present disclosure does not limit this.

[0034] See also Figure 2 and Figure 3 In this embodiment, the nozzle of the full liquid inlet section 21 is arranged downward. The liquid collecting part 30 includes a side wall 31, a bottom wall 32 and a connecting part 33. The side wall 31 is cylindrical and surrounds the periphery of the full liquid inlet section 21, and the bottom wall 32 is arranged at the bottom of the side wall 31. The bottom wall 32 and the side wall 31 are enclosed to form a liquid collecting cavity 39, and the bottom of the liquid collecting cavity 39, that is, the bottom wall 32, is lower than the nozzle of the full liquid inlet section 21. The connecting part 33 is connected between the side wall 31 and the full liquid inlet section 21 to connect and fix the side wall 31 to the full liquid inlet section 21. The liquid collecting part 30 is also provided with a full liquid inlet 38 that connects the liquid collecting cavity 39 with the interior of the tank body 10. At the same time, the connecting part 33 is also provided with a passage for liquid circulation. The liquid collecting chamber 39 is connected to the interior of the tank body 10 through the full liquid inlet 38 , and the minimum flow area of ​​the communication channel is greater than the flow area of ​​the full liquid inlet section 21 .

[0035] The full liquid inlet 38 can be arranged at any position on the liquid collecting member 30, as long as the bottom of the liquid collecting member 30 is at the effective volume liquid level of the liquefied gas container (i.e. Figures 2 to 17 as well as Figures 19 to 20 The dotted line in the figure) is flush with and higher than the nozzle of the liquid inlet section 21. In the present embodiment, it is arranged at the top of the side wall 31.

[0036] During the filling process, the side wall 31 and the bottom wall 32 of the liquid collecting part 30 can prevent most of the waves in the tank body from approaching and entering the nozzle of the full liquid inlet section 21. When the liquid is filled to a height close to the effective volume liquid level, part of the liquid will enter the liquid collecting chamber 39 after passing the full liquid inlet 38. Since the space of the liquid collecting chamber is relatively small compared to the tank body, no large waves can be formed. Moreover, the bottom of the liquid collecting chamber 39 is lower than the full liquid inlet section 21, and there is still a distance from the upper surface of the liquid in the liquid collecting chamber 39 to the nozzle of the full liquid inlet section 21. At this time, the liquid in the liquid collecting chamber 39 cannot enter the full measuring tube 20. When the liquid is filled to the effective volume liquid level, the liquid passes the full liquid inlet and enters the liquid collecting chamber 39 in large quantities, so that the liquid in the liquid collecting chamber 39 rises and submerges the nozzle of the full liquid inlet section 21. The liquid flows out through the full measuring tube 20, indicating that the liquid has been filled to the effective volume liquid level. The invention solves the technical problem in the prior art that it is impossible to accurately judge whether the container is filled to the effective volume through the overflow pipe.

[0037] The connecting member 33 may be a connecting plate, on which a plurality of overflow holes 331 are formed. The plurality of overflow holes 331 are evenly arranged on the connecting plate around the fullness measuring tube 20. It is understandable that the plurality of overflow holes 331 may also be concentrated on a side of the connecting plate away from the filling port of the liquefied gas container. The number of the overflow holes may be 2, 5, 11, etc., which is not limited in the present disclosure, but the total flow area of ​​the plurality of overflow holes 331 must be greater than the flow area of ​​the fullness measuring liquid inlet section 21.

[0038] Understandable, such as Fig.16 and 17 As shown, the above-mentioned connecting member 33 can also be a plurality of connecting ribs arranged at intervals, and the plurality of connecting ribs are evenly arranged around the fullness measuring tube. The intervals between the plurality of connecting ribs form a passage for liquid circulation. It can be understood that the plurality of connecting ribs can also be concentrated on the side of the fullness measuring tube away from the filling port of the liquefied gas container. The number of the above-mentioned connecting ribs can be 2, 4, 8, etc., which is not limited in the present disclosure, but the total flow area of ​​the passage for liquid circulation between the plurality of connecting ribs must be greater than the flow area of ​​the fullness measuring liquid inlet section 21.

[0039] Please continue reading Figure 2 and Figure 3It is understandable that the above-mentioned liquefied gas container may further include a wave shield 40, which surrounds the liquid collecting part 30 and surrounds the full liquid inlet 38 therein, so as to shield most of the waves in the tank body 10 and prevent them from entering the liquid collecting part 30 through the full liquid inlet 38. The interior of the wave shield 40 is communicated with the full liquid inlet 38, and an opening 48 is provided thereon which is communicated with the interior of the tank body 10, so as to connect the interior of the tank body 10 with the liquid collecting chamber 39. In particular, the opening 48 needs to be lower than the full liquid inlet 38, so as to prevent the waves from directly entering the full liquid inlet 38 after passing over the opening 48, resulting in a large amount of liquid accumulating in the liquid collecting chamber 39.

[0040] In this embodiment, the wave shield 40 includes a shield wall 41 and a shield cover plate 42. The shield wall 41 is cylindrical and surrounds the liquid collecting member 30, and is spaced apart from the liquid collecting member 30. In particular, the above-mentioned opening 48 is formed between the bottom end of the shield wall 41 and the side wall 31.

[0041] The cover plate 42 is arranged at the top of the cover wall 41 to close the top of the wave shield 40. The cover plate 42 is also provided with a through hole 421, through which the full liquid inlet section 21 of the full-fill pipe 20 passes, and is welded and fixed to the wave shield 40 at the through hole 421.

[0042] At the same time, it can be understood that in order to ensure the fixing strength of the cover plate 42 and the full liquid inlet section 21, a circle of reinforcing ribs can also be set around the full liquid inlet section on the top of the cover plate 42 to increase the contact area between the cover plate 42 and the full liquid inlet section 21, and clamp the full liquid inlet section 21 to strengthen the fixing strength of the cover plate 42 and the full liquid inlet section 21.

[0043] When the wave-breaking shield 40 is present, during the filling process, the cover plate 42, the shield wall 41, and the side wall 31 and the bottom wall 32 of the liquid collecting part 30 of the wave-breaking shield 40 can block most of the waves in the tank from approaching and entering the nozzle of the full liquid inlet section 21. When the liquid is filled to a height close to the effective volume liquid level, part of the liquid passes through the opening 48 and the full liquid inlet 38 to enter the liquid collecting chamber 39. Since the gap between the shield wall 41 and the side wall 31 and the gap between the side wall 31 and the full liquid inlet section 21 are relatively small, no large waves can be formed. In addition, the bottom end of the liquid collecting chamber 39 is lower than the full liquid inlet section 21, and there is still a distance from the upper surface of the liquid in the liquid collecting chamber 39 to the nozzle of the full liquid inlet section 21. At this time, the liquid in the liquid collecting chamber 39 cannot enter the full liquid measuring tube 20. When the liquid is filled to the effective volume liquid level, the liquid as Figure 2 The route shown by the middle arrow passes through the opening 48 and approaches the full liquid inlet 38, then passes over the full liquid inlet and enters the liquid collecting chamber 39 in large quantities, causing the liquid in the liquid collecting chamber 39 to rise above the pipe opening of the full liquid inlet section 21, and the liquid flows out through the full liquid measuring pipe 20, indicating that the liquid has been filled to the effective volume liquid level height.

[0044] It is understandable that in this disclosure Figure 4 and Figure 5 In another embodiment shown, the top of the wave shield 40 is not closed, that is, it does not include a cover plate 42. In this embodiment, the wave shield 40 includes not only a shield wall 41, but also a shield connector 43, which is connected between the shield wall 41 and the liquid collecting member 30 to connect the shield wall 41 and the liquid collecting member 30 as a whole. At the same time, a passage for liquid circulation is formed on the shield connector 43.

[0045] The cover connector 43 can be a connecting plate, on which a plurality of through holes are provided, namely, openings 48, which are evenly arranged on the connecting plate around the liquid collecting member 30. It is understandable that the plurality of through holes can also be concentrated on the side of the connecting plate away from the filling port of the liquefied gas container. The number of the above-mentioned through holes can be 2, 5, 11, etc., which is not limited in the present disclosure, but the total flow area of ​​the plurality of through holes must be greater than the flow area of ​​the full liquid inlet section 21. When the cover connector 43 is a connecting plate, it can further block more waves from entering the gap between the wave shield 40 and the liquid collecting member 30 through the opening 48 and entering the liquid collecting chamber 39 across the full liquid inlet 38, thereby avoiding the accumulation of a large amount of liquid in the liquid collecting chamber 39. If a large amount of liquid accumulates in the liquid collecting chamber 39, the liquid in the liquid collecting chamber 39 will not pass through the nozzle of the full liquid inlet section 21 before being filled to the effective volume liquid level height, thereby causing part of the liquid to flow out, resulting in inaccurate detection results.

[0046] Understandable, such as Fig.16 and 17 As shown, the cover connector 43 can also be a plurality of spaced connecting ribs, which are evenly arranged around the liquid collecting member 30. The intervals between the plurality of connecting ribs form a passage for liquid circulation. It can be understood that the plurality of connecting ribs can also be concentrated on the side of the full measuring tube away from the filling port of the liquefied gas container. The number of the above-mentioned connecting ribs can be 2, 4, 8, etc., which is not limited in the present disclosure, but the total flow area of ​​the passage for liquid circulation between the plurality of connecting ribs must be greater than the flow area of ​​the full measuring liquid inlet section 21.

[0047] It can be understood that the bottom end of the cover wall 41 is flush with the bottom end of the side wall 31, and the cover connector 43 is arranged at the bottom end of the side wall 31, flush with the bottom wall 32, and connects the bottom end of the cover wall 41 with the bottom end of the side wall 31. The connector 33 can also be arranged at the top end of the side wall 31. Figure 6 and Figure 7 In the illustrated embodiment, the wave-breaking shield 40 and the liquid collecting member 30 are an integrally formed structure.

[0048] It is understandable that in this disclosure Figure 8 and Fig. 9In another embodiment shown, the above-mentioned wave-breaking shield 40 may also include both a shield cover plate 42 and a shield connector 43. The full-fill liquid inlet section 21 of the full-fill tube 20 passes through the through hole 421 and is welded and fixed to the wave-breaking shield 40 at the through hole 421. The shield connector 43 is a connecting plate, which connects the shield wall 41 and the liquid collecting part 30 as a whole. At this time, the above-mentioned liquid collecting part 30 may be indirectly connected to the full-fill tube 20 through the wave-breaking shield 40, and it may not include the connector 33, forming a liquid collecting chamber 39 open upward. At the same time, the above-mentioned openings 48 may be set on the shield connector 43, or may be evenly distributed on the shield wall 41. Figure 8 In the illustrated embodiment, the opening 48 is provided on the cover connecting part 43 .

[0049] exist Figure 8 and 9 In the illustrated embodiment, the cover connector 43 can not only make the liquid collecting part 30 and the wave shield 40 fixedly connected, but also further prevent more waves from entering the gap between the wave shield 40 and the liquid collecting part 30 through the opening 48 and entering the liquid collecting chamber 39 over the full liquid inlet 38, thereby preventing a large amount of liquid from accumulating in the liquid collecting chamber 39. This prevents the liquid in the liquid collecting chamber 39 from flooding the pipe opening of the full liquid inlet section 21 before being filled to the effective volume liquid level, thereby causing part of the liquid to flow out, resulting in inaccurate detection results. This not only simplifies the structure of the liquefied gas container, but also enhances the wave-proof effect of the liquid collecting part 30 and the wave shield 40.

[0050] It is understandable that in this disclosure Fig.10 and Fig.11 In another embodiment shown, the bottom end of the cover wall 41 is flush with the bottom end of the side wall 31, and the cover connector 43 is disposed at the bottom end of the side wall 31, flush with the bottom wall 32, and connects the bottom end of the cover wall 41 with the bottom end of the side wall 31. The openings 48 are evenly distributed on the cover wall 41, and are lower than the full liquid inlet 38, that is, lower than the top end of the side wall 31 of the liquid collecting member 30. At the same time, further, the wave shield 40 and the liquid collecting member 30 are an integrally formed structure.

[0051] During the filling process, the wave shield 40 and the liquid collecting part 30 can block most of the waves in the tank from approaching and entering the pipe opening of the full liquid inlet section 21. If some waves pass over the opening 48, if their horizontal speed is not fast enough, they can only enter the gap between the wave shield 40 and the liquid collecting part 30, and fall on the cover connector 43, and cannot approach the full liquid inlet section 21. If their horizontal speed is fast enough, they will enter the liquid collecting chamber 39 after passing the full liquid inlet 38. Since the gap between the cover wall 41 and the side wall 31 and the gap between the side wall 31 and the full liquid inlet section 21 are relatively small, large waves cannot be formed. In addition, the bottom end of the liquid collecting chamber 39 is lower than the full liquid inlet section 21, and there is still a distance from the upper surface of the liquid in the liquid collecting chamber 39 to the pipe opening of the full liquid inlet section 21. At this time, the liquid in the liquid collecting chamber 39 cannot enter the full liquid inlet tube 20. When the liquid is filled to the effective volume liquid level height, the liquid passes through the opening 48 and approaches the full liquid inlet 38, then passes over the full liquid inlet and enters the liquid collecting chamber 39 in large quantities, causing the liquid in the liquid collecting chamber 39 to rise above the pipe mouth of the full liquid inlet section 21, and the liquid flows out through the full liquid measuring tube 20, indicating that the liquid has been filled to the effective volume liquid level height.

[0052] It can be understood that a plurality of through holes may also be provided on the cover connecting member 43 to discharge the liquid thereon, so as to avoid a large amount of liquid accumulating between the wave-breaking cover 40 and the liquid collecting member 30 and further accumulating a large amount of liquid in the liquid collecting chamber 39 .

[0053] It is understandable that in this disclosure Fig.12 and Fig.13 In another embodiment shown, the above-mentioned wave shield 40 includes both a shield cover plate 42 and a shield connector 43, and the openings 48 are evenly distributed on the shield wall 41. At the same time, the above-mentioned liquid collecting member 30 may also include a connector 33, and the connector 33 may be arranged at the top of the side wall 31 to close the top of the liquid collecting member 30, that is, the overflow hole 331 may not be provided thereon. At this time, a through hole surrounding the liquid collecting member 31 may be provided on the side wall 31, serving as a full liquid inlet 38 connecting the liquid collecting cavity 39 with the inside of the tank body 10. The bottom end of the full liquid inlet 38 is higher than the top end of the opening 48, and under this structure, the flow area of ​​the full liquid inlet 38 and the opening 48 is generally the minimum flow area of ​​the connecting channel, which must be larger than the flow area of ​​the full liquid inlet section 21.

[0054] It is understandable that in this disclosure Fig.14 and Fig.15 In another embodiment shown, the openings 48 and the full liquid inlet 38 are arranged in a staggered manner to prevent some waves from passing through the openings 48 and directly passing through the full liquid inlet 38 into the liquid collecting chamber 39 if their horizontal speed is fast enough, thereby further reducing the possibility of a large amount of liquid accumulating in the liquid collecting chamber 39.

[0055] Understandable, such as Figures 18 to 20As shown, the mouth of the fullness measuring tube 20 can also be set upward. In this case, a mounting hole 321 is provided on the bottom of the liquid collecting part 30, that is, the bottom wall 32 thereof. The fullness measuring liquid inlet section 21 of the fullness measuring tube 20 passes through the mounting hole 321 and is sealed and fixed on the bottom wall 32. For example, full-circle welding is used in this embodiment.

[0056] It can be understood that when the nozzle of the full measuring tube 20 can also be arranged upward, the liquefied gas container can also include a wave shield 40, which surrounds the liquid collecting part 30 and surrounds the full measuring liquid inlet 38 therein, so as to shield part of the waves in the tank body 10 and prevent them from entering the liquid collecting part 30 through the full measuring liquid inlet 38. The interior of the wave shield 40 is communicated with the full measuring liquid inlet 38, and an opening 48 is provided on the wave shield 40, which is communicated with the interior of the tank body 10, so as to connect the interior of the tank body 10 with the liquid collecting chamber 39, and in particular, the opening 48 needs to be lower than the full measuring liquid inlet 38.

[0057] In this embodiment, the wave-breaking shield 40 includes a shield wall 41, a shield cover plate 42 and a shield connector 43. The shield wall 41 is cylindrical and surrounds the liquid collecting part 30, and is spaced apart from the liquid collecting part 30. In particular, the above-mentioned opening 48 is formed between the bottom end of the shield wall 41 and the side wall 31. The shield cover plate 42 is disposed at the top end of the shield wall 41 to close the top of the wave-breaking shield 40. The shield connector 43 is connected between the shield wall 41 and the liquid collecting part 30 to connect the shield wall 41 and the liquid collecting part 30 as a whole. At the same time, a passage for liquid circulation, i.e., an opening 48, is formed on the shield connector 43.

[0058] The cover connector 43 can be a connecting plate, on which a plurality of through holes are formed, namely, openings 48, which are evenly arranged on the connecting plate around the liquid collecting member 30. It can be understood that the plurality of through holes can also be concentrated on the side of the connecting plate away from the filling port of the liquefied gas container. The number of the above-mentioned through holes can be 2, 5, 11, etc., which is not limited in the present disclosure, but the total flow area of ​​the plurality of through holes must be greater than the flow area of ​​the full liquid inlet section 21.

[0059] It is understandable that the cover connector 43 can also be a plurality of spaced connecting ribs, which are evenly arranged around the liquid collecting member 30. The intervals between the plurality of connecting ribs form a passage for liquid circulation. It is understandable that the plurality of connecting ribs can also be concentrated on the side of the full measuring tube away from the filling port of the liquefied gas container. The number of the above-mentioned connecting ribs can be 2, 4, 8, etc., which is not limited in the present disclosure, but the total flow area of ​​the passage for liquid circulation between the plurality of connecting ribs must be greater than the flow area of ​​the full measuring liquid inlet section 21.

[0060] It can be understood that the bottom end of the cover wall 41 can be flush with the bottom end of the side wall 31, and the cover connector 43 can be arranged at the bottom end of the side wall 31, flush with the bottom wall 32, and connect the bottom end of the cover wall 41 with the bottom end of the side wall 31. At the same time, further, the wave shield 40 and the liquid collecting member 30 can be an integrally formed structure.

[0061] At the same time, it can be understood that in order to ensure the fixing strength of the bottom wall 32 and the full liquid inlet section 21, a circle of reinforcing ribs can also be set around the full liquid inlet section at the bottom of the bottom wall 32 to increase the contact area between the bottom wall 32 and the full liquid inlet section 21, and clamp the full liquid inlet section 21 to strengthen the fixing strength of the bottom wall 32 and the full liquid inlet section 21.

[0062] Although the present disclosure has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present disclosure can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
