[0034] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0035] A large buffer tank is usually configured for large compressor units. Due to the deviation in air flow pulsation control, there is a phase difference between the alternating pulsation forces of the cylinders, which leads to a large pulsation unbalanced force from the air intake to the buffer tank, excessive vibration of the buffer tank, and large bending deformation of the nozzle connected to the buffer tank, resulting in abnormal breakage of the bolts used for the nozzle external pipe and cracking of the nozzle. Therefore, how to suppress the vibration of the buffer tank to prevent abnormal breakage of the bolts used for the nozzle external pipe and cracking of the nozzle has become an urgent problem to be solved.

[0036] In order to solve the technical problem in the related art that vibration of the buffer tank leads to abnormal breakage of bolts used for the external pipe of the nozzle and cracking of the nozzle, the present application provides a buffer tank 10 and a buffer tank group 20.

[0037] See also Figure 1 to Figure 2 In a first aspect of the present application, a buffer tank 10 is provided. The buffer tank 10 comprises a tank body 11, a partition plate 12 and a filter tube 13. The tank cavity of the tank body 11 is used to receive and buffer the gas to be buffered, so that the gas to be buffered is buffered during the transportation process in the tank cavity of the tank body 11, the pressure fluctuation of the gas is reduced, and the gas is output to the downstream equipment at a stable pressure.

[0038] The center line of the tank body 11 is usually set to be horizontal. The tank body 11 is provided with a first gas inlet 111, a first gas outlet 112 and a second gas outlet 113. The first gas inlet 111 is used for inputting the gas to be buffered in the tank cavity of the tank body 11, and the first gas outlet 112 and the second gas outlet 113 are respectively used for outputting the buffered gas in the tank cavity of the tank body 11.

[0039] The partition plate 12 is installed in the tank body 11. The partition plate 12 is usually perpendicular to the center line of the tank body 11, and the tank cavity of the tank body 11 is divided into a first chamber 18 and a second chamber 19 along the center line direction. The first gas inlet 111 and the first gas outlet 112 are respectively connected to the first chamber 18. The first gas inlet 111 is used for the input of the gas to be buffered in the tank cavity of the tank body 11, and the first gas outlet 112 is used for the output of the gas that has been buffered in the tank cavity of the tank body 11. The second gas outlet 113 is connected to the second chamber 19, and is used to output the gas that has been buffered in the second chamber 19 of the tank body 11. In some embodiments, the partition plate 12 can also be set at an angle to the center line of the tank body 11, which can be set according to actual needs, and this application does not limit it.

[0040] It should be noted that the tank cavity of the tank body 11 can be connected to the compressor unit and the pipeline gas supply pipe 21 through the first gas supply port 111. The tank body 11 can be used to buffer the gas output by the compressor unit, so that the gas output by the compressor passes through the buffer tank 10, thereby reducing the pulsating unbalanced force of the air entering the tank cavity of the tank body 11, thereby reducing the vibration of the tank body 11, thereby preventing the nozzle connected to the tank body 11 from bending and deformation, and preventing the abnormal breakage of the bolts used for the external pipe of the nozzle and the cracking of the nozzle.

[0041] The filter tube 13 may be a hollow tube. The filter tube 13 passes through the partition plate 12 and communicates with the first chamber 18 and the second chamber 19 , so that the filter tube 13 can transport the gas in the first chamber 18 to the second chamber 19 . Since the first chamber 18 and the second chamber 19 are connected through the filter tube 13, part of the gas transported to the first chamber 18 through the first gas delivery port 111 is discharged through the first gas outlet 112, and the other part of the gas is transported to the second chamber 19 through the filter tube 13 and discharged through the second gas outlet 113. The filter tube 13 realizes the effective connection between the first chamber 18 and the second chamber 19, which can extend the gas transportation path in the tank cavity of the tank body 11, increase the buffering time of the tank body 11 on the gas, balance the pressure fluctuation of the gas in the first chamber 18 and the second chamber 19, reduce the pulsating unbalanced force of the gas in the tank cavity of the tank body 11, improve the buffering effect of the tank body 11 on the gas, reduce the pressure fluctuation of the gas, reduce the pulsating unbalanced force in the tank body 11, and thus reduce the vibration of the buffer tank 10, thereby preventing the nozzle connected to the buffer tank 10 from bending and deformation, and preventing the bolts used for the nozzle external pipe from abnormal breakage and the nozzle from cracking.

[0042] The volume of the first chamber 18 is usually larger than that of the second chamber 19. The first gas outlet 111 is connected to the first chamber 18, which can quickly relieve pressure, reduce the pulsating unbalanced force in the tank body 11, and ensure stable output of gas in the tank cavity of the tank body 11, thereby reducing the vibration of the tank body 11.

[0043] In order to further extend the gas delivery path in the tank cavity of the tank body 11, please refer to Figure 1, both ends of the filter tube 13 are sealed, and the buffer tank 10 also includes a plurality of filter branch pipes 14, which are hollow tubular. The plurality of filter branch pipes 14 are respectively arranged on the circumferential sides of the two ends of the filter tube 13 and are respectively connected to the filter tube 13, so that a part of the gas in the first chamber 18 can be discharged through the first gas outlet 112, and the other part needs to enter the filter tube 13 through the plurality of filter branch pipes 14, and be transported to the second chamber 19 through the filter tube 13, and be discharged through the plurality of filter branch pipes 14, so that the gas transportation path in the tank cavity of the tank body 11 can be extended through the filter tube 13 and the filter branch pipe 14, the buffering effect time of the tank body 11 on the gas is increased, the buffering effect of the tank body 11 on the gas is improved, the pressure fluctuation of the gas is reduced, the pulsating unbalanced force in the tank body 11 is reduced, and the vibration of the buffer tank 10 is reduced.

[0044] The axis of the filter branch pipe 14 is perpendicular to the axis of the filter tube 13, and can also form any angle with the axis of the filter tube 13. By adjusting the angle between the axis of the filter branch pipe 14 and the axis of the filter tube 13, the inlet of the filter branch pipe 14 can be directed toward the first gas delivery port 111, so that as much gas as possible delivered to the first chamber 18 through the first gas delivery port 111 can be delivered to the filter tube 13 through multiple filter branch pipes 14, delivered to the second chamber 19 through the filter tube 13, and discharged through multiple filter branch pipes 14, which can extend the delivery path of the gas in the tank cavity of the tank body 11, increase the buffering effect time of the tank body 11 on the gas, improve the buffering effect of the tank body 11 on the gas, reduce the pressure fluctuation of the gas, reduce the pulsating unbalanced force in the tank body 11, and thus reduce the vibration of the buffer tank 10.

[0045] In some embodiments, both ends of the filter tube 13 may also be open respectively, so that the gas delivered to the first chamber 18 through the first gas delivery port 111 can be delivered to the filter tube 13 through the open port of the filter tube 13 located in the first chamber 18, and discharged through the open port of the filter tube 13 located in the second chamber 19, and the gas is delivered to the second chamber 19 through the filter tube 13, which can also extend the gas delivery path in the tank cavity of the tank body 11 to a certain extent.

[0046] In some embodiments, in order to increase the buffering time of the gas to be buffered in the tank cavity of the tank body 11, a plurality of filter tubes 13 can be provided, and the plurality of filter tubes 13 are parallel and respectively arranged in the partition plate 12, so that the gas in the first chamber 18 can be transported to the second chamber 19 through the plurality of filter tubes 13. The provision of the plurality of filter tubes 13 can increase the gas transport pipeline from the first chamber 18 to the second chamber 19, and increase the gas transport volume from the first chamber 18 to the second chamber 19, which can increase the buffering time of the gas to be buffered in the tank cavity of the tank body 11 to a certain extent, improve the buffering effect of the tank body 11 on the gas to be buffered, reduce the pressure fluctuation of the gas, reduce the pulsating unbalanced force in the tank body 11, and thereby reduce the vibration of the buffer tank 10.

[0047] In order to allow as much of the gas to be buffered as possible that is delivered to the first chamber 18 through the first gas delivery port 111 to be delivered to the second chamber 19 through the filter tube 13 to increase the buffering time of the gas to be buffered in the tank cavity of the tank body 11, the tank body 11 extends along a preset direction (the preset direction can be understood as the centerline direction of the tank body 11), the filter tube 13 extends along a preset direction and the two ends of the filter tube 13 are respectively close to the first gas outlet 112 and the second gas outlet 113, so that as much of the gas delivered to the first chamber 18 through the first gas delivery port 111 as possible is delivered to the filter tube 13 through the filter branch pipe 14, delivered to the second chamber 19 through the filter tube 13, and discharged through multiple filter branch pipes 14, thereby increasing the buffering time of the gas to be buffered in the tank cavity of the tank body 11 and improving the buffering effect of the tank body 11 on the gas to be buffered.

[0048] In order to prevent the gas delivered to the first chamber 18 through the first gas delivery port 111 from being discharged directly through the first gas outlet 112, the first gas delivery port 111 is far away from the first gas outlet 112, so that the gas delivered to the first chamber 18 through the first gas delivery port 111 needs to be delivered from the first gas delivery port 111 to the second gas outlet 113 in the first chamber 18 for discharge. Since the first gas outlet 112 is far away from the first gas delivery port 111, the delivery path of the gas in the tank body 11 can be extended, the buffering time of the tank body 11 on the gas is increased, the buffering effect of the tank body 11 on the gas is improved, the pressure fluctuation of the gas is reduced, the pulsation unbalanced force in the tank body 11 is reduced, and the vibration of the buffer tank 10 is reduced.

[0049] To facilitate the connection of the buffer tank 10, please refer to Figure 1 to Figure 2The buffer tank 10 includes a first nozzle 15, a second nozzle 16 and a third nozzle 17. The first nozzle 15 is connected to the first gas delivery port 111, and the end of the first nozzle 15 away from the first gas delivery port 111 is connected to the first flange 151. The second nozzle 16 is connected to the first gas outlet 112, and the end of the second nozzle 16 away from the first gas outlet 112 is connected to the second flange 161. The third nozzle 17 is connected to the second gas outlet 113, and the end of the third nozzle 17 away from the first gas outlet 112 is connected to the third flange 171. In this way, the first gas delivery port 111 is connected to the pipeline gas delivery pipe 21 through the first nozzle 15 using the first flange 151, the first gas outlet 112 is connected to the gas outlet pipeline through the second nozzle 16 using the second flange 161, and the second gas outlet 113 is connected to the gas outlet pipeline through the third nozzle 17 using the third flange 171. The flange connection is simple and reliable, and the sealing performance is good.

[0050] The second aspect of the present application provides a buffer tank group 20, see Figure 1 to Figure 2 The buffer tank group 20 includes a pipeline gas pipe 21, the above-mentioned buffer tank 10 and a buffer single tank 22. The buffer tank 10 is connected to the pipeline gas pipe 21 through a first nozzle 15 connected to the first gas port 111 and using a first flange 151. The buffer single tank 22 includes a single tank body 25, and the single tank body 25 is provided with a second gas port 221 and a third gas outlet (not shown in the figure). The second gas port 221 and the third gas outlet are respectively connected to the tank cavity of the single tank body 25. The buffer single tank 22 is connected to the pipeline gas pipe 21 through the second gas port 221. In this way, the gas transported through the pipeline gas pipe 21 can buffer the pressure fluctuation of the gas to be buffered through the buffer single tank 22, reduce the pulsating unbalanced force in the single tank body 25, and then reduce the vibration of the buffer single tank 22, thereby preventing the nozzle connected to the buffer single tank 22 from bending and deformation, and preventing the bolts used for the nozzle external pipeline from abnormally breaking and the nozzle from cracking.

[0051] The tank cavity volume of the tank body 11 is larger than the tank cavity volume of the single tank body 25. The gas transported by the pipeline gas pipe 21 can be transported to the tank cavity of the tank body 11 as much as possible. The filter tube 13 in the tank body 11 can realize effective connection between the first chamber 18 and the second chamber 19, which can extend the gas transportation path in the tank cavity of the tank body 11, increase the buffering time of the tank body 11 on the gas, balance the air pressure in the first chamber 18 and the second chamber 19, reduce the pulsating unbalanced force of the tank body 11 of the buffer tank 10, improve the buffering effect of the tank body 11 on the gas, reduce the pressure fluctuation of the gas, reduce the pulsating unbalanced force in the tank body 11, and then reduce the vibration of the buffer tank 10, thereby preventing the nozzle connected to the buffer tank 10 from having large bending deformation, and preventing abnormal breakage of the bolts used for the external pipe of the nozzle and cracking of the nozzle.

[0052] It should be noted that the tank body 11 is connected to the pipeline gas pipe 21 of the compressor unit through the first flange 151 connected to the first gas delivery port 111, and the single tank body 25 can be connected to the exhaust port of the compressor unit through the second gas delivery port 221. The tank body 11 and the single tank body 25 can be used to buffer the gas output by the compressor unit, so that the gas output by the compressor passes through the buffer of the buffer tank 10, reduces the pressure fluctuation of the gas, reduces the pulsating unbalanced force of the gas in the tank body 11 and the buffer single tank 22, and then reduces the vibration of the buffer tank 10 and the buffer single tank 22, thereby preventing the nozzles connected to the tank body 11 and the buffer single tank 22 from bending and deformation, and preventing the abnormal breakage of the bolts used for the external pipe of the nozzle and the cracking of the nozzle.

[0053] In some embodiments, a plurality of buffer tanks 10 and a plurality of buffer single tanks 22 may be respectively provided, and the plurality of buffer tanks 10 and the plurality of buffer single tanks 22 may be respectively connected to the pipeline gas pipe 21. Compared with the provision of a single buffer tank 10, the plurality of buffer tanks 10 and the plurality of buffer single tanks 22 are simultaneously connected to the pipeline gas pipe 21, which can greatly reduce the pulsating unbalanced force in each tank body 11 and each buffer single tank 22, thereby reducing the vibration in each tank body 11 and each buffer single tank 22.

[0054] In order to facilitate the connection of the buffer tank 22, the buffer tank 22 also includes a fourth nozzle 23 and a fifth nozzle 24. The fourth nozzle 23 is connected to the second gas delivery port 221, and the end of the fourth nozzle 23 away from the second gas delivery port 221 is connected to a fourth flange 231. The fifth nozzle 24 is connected to the third gas outlet, and the end of the fifth nozzle 24 away from the third gas outlet is connected to a fifth flange 241, so that the second gas delivery port 221 can be connected to the pipeline gas delivery pipe 21 through the fourth nozzle 23 using the fourth flange 231, and the third gas outlet can be connected to the gas outlet pipeline through the fifth nozzle 24 using the fifth flange 241. The flange connection is simple and reliable, and the sealing is good.

[0055] The third aspect of the present application provides a buffer tank group 20, which may also include a pipeline gas pipe 21 and the above-mentioned buffer tank 10, and the buffer tank 10 may be connected to the pipeline gas pipe 21 through a first nozzle 15 and a first flange 151 connected to the first gas port 111. At the same time, the buffer tank 10 may be provided with multiple buffer tanks 10 and respectively connected to the pipeline gas pipe 21, so that the gas can be transported to different buffer tanks 10 to buffer the pressure fluctuation of the gas, reduce the pulsating unbalanced force in the tank body 11, and make the gas output stable, thereby reducing the vibration of the buffer tank 10, thereby preventing the nozzle connected to the buffer tank 10 from bending and deformation, and preventing the bolts used for the nozzle external pipeline from abnormally breaking and the nozzle from cracking.

[0056] It should be noted that the tank body 11 can be connected to the pipeline gas pipeline 21 of the compressor unit through the pipeline gas pipeline 21, and the tank body 11 can be used to buffer the gas output by the compressor unit.

[0057] Compared with the arrangement of a single buffer tank 10 , multiple buffer tanks 10 are simultaneously connected to the pipeline gas pipe 21 , which can significantly reduce the pulsating unbalanced force in each tank body 11 , thereby reducing the vibration of each buffer tank 10 .
