Description

Technical Field

[0001] This utility model relates to the field of buffer tanks, and in particular to a buffer tank with a pressure relief structure. Background Technology

[0002] In industrial production and various engineering applications, buffer tanks are a widely used piece of equipment. Their main function is to buffer and regulate parameters such as fluid pressure and flow rate, ensuring the stable operation of the entire system.

[0003] However, most existing buffer tanks often lack effective pressure relief structures. When the pressure inside the tank rises abnormally due to various reasons (such as a sudden increase in fluid input or system failure), the pressure cannot be released in time. This can easily lead to serious safety accidents such as tank rupture and explosion, causing not only equipment damage and production stoppage, but also threatening the lives of operators. Secondly, existing buffer tanks have poor buffering effect on the inflowing liquid. The liquid directly impacts the tank wall, generating a large impact force and a high flow velocity. Over time, this will cause serious wear and damage to the tank body, greatly shortening the service life of the buffer tank. To solve the above problems, we propose a buffer tank with a pressure relief structure. Utility Model Content

[0004] The main objective of this invention is to provide a buffer tank with a pressure relief structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A buffer tank with a pressure relief structure includes a buffer tank outer shell, a liquid inlet fixedly connected to the front end of the buffer tank outer shell, a drain pipe fixedly connected to the lower end of the buffer tank outer shell, a pressure relief outer shell fixedly connected to the upper end of the buffer tank outer shell, a venting assembly provided in the inner cavity of the pressure relief outer shell, an exhaust head fixedly connected to the upper end of the pressure relief outer shell, and two buffer plates fixedly connected to the inner cavity of the buffer tank outer shell, with multiple through holes opened on the outer sides of the two buffer plates.

[0007] Preferably, the venting assembly includes a limiting barrel, which is fixedly connected to the upper end of the buffer tank shell. A connecting pipe is fixedly connected to the inner side of the limiting barrel, and the connecting pipe is fixedly connected to the upper end of the buffer tank shell. The inner cavity of the connecting pipe is connected to the inner cavity of the buffer tank shell. A venting head is fixedly connected to the upper end of the connecting pipe, and multiple venting holes are provided on the outer side of the venting head.

[0008] Preferably, a sealing cover is fitted on the outer side of the vent head, and the sealing cover and the vent head are designed to be sealed. A breathable ring-shaped limiting plate is fixedly connected to the lower end of the sealing cover. An insertion groove is formed between the limiting barrel and the connecting pipe, and the breathable ring-shaped limiting plate is inserted into the inner side of the insertion groove.

[0009] Preferably, two connecting plates are fixedly connected to the outer side of the sealing cover, and telescopic tubes are fixedly connected to the lower ends of the two connecting plates. The lower ends of the two telescopic tubes are respectively fixedly connected to the outer shell of the buffer tank, and elastic pressing components are provided at the upper ends of the two connecting plates.

[0010] Preferably, the elastic pressing assembly includes a telescopic rod, the upper and lower ends of which are fixedly connected to the pressure relief housing and the connecting plate, respectively. A strong spring is sleeved on the outer side of the telescopic rod, and the upper and lower ends of the strong spring are also fixedly connected to the pressure relief housing and the connecting plate, respectively.

[0011] Preferably, sliders are fixedly connected to the outer sides of both connecting plates, and two sliding blocks corresponding to the sliders are fixedly connected to the inner wall of the pressure relief housing, with the sliders slidably connected to the inner side of the sliding blocks.

[0012] Preferably, the lower end of the buffer tank shell is fixedly connected to two support legs, which are respectively located at the front and rear ends of the sewage pipe. An alarm is installed at the upper end of the buffer tank shell, and the alarm is located at the rear end of the exhaust head.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This buffer tank with a pressure relief structure can release pressure when the internal pressure rises abnormally due to sudden changes in fluid input or system failure. Compressed gas will expand and contract through the telescopic pipe and impact the connecting plate, overcoming the spring force to drive the sealing cover and the vent ring limit plate to move upward, exposing the vent hole and releasing the gas through the exhaust head. This avoids serious safety accidents such as tank rupture and explosion caused by excessive pressure, effectively ensuring equipment safety, maintaining production continuity, and greatly reducing the threat to the life safety of operators.

[0015] 2. This type of buffer tank with a pressure relief structure allows liquid to first impact the buffer plate with through holes when it flows in, thus buffering and dispersing the flow velocity and impact force, preventing direct impact on the tank wall. This greatly reduces the wear and damage to the tank body caused by the liquid, effectively extends the service life of the buffer tank, reduces equipment replacement and maintenance costs, and ensures that the buffer tank can stably buffer and regulate parameters such as fluid pressure and flow rate for a long time, ensuring the stable operation of the entire system.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, a buffer tank with a pressure relief structure includes a buffer tank shell 1, an inlet 2 fixedly connected to the front end of the buffer tank shell 1, a drain pipe 3 fixedly connected to the lower end of the buffer tank shell 1, a pressure relief shell 6 fixedly connected to the upper end of the buffer tank shell 1, a venting assembly provided in the inner cavity of the pressure relief shell 6, an exhaust head 7 fixedly connected to the upper end of the pressure relief shell 6, and two buffer plates 8 fixedly connected to the inner cavity of the buffer tank shell 1, with multiple through holes 9 opened on the outer side of each of the two buffer plates 8.

[0024] In this embodiment, the venting assembly includes a limiting barrel 10, which is fixedly connected to the upper end of the buffer tank outer shell 1. A connecting pipe 11 is fixedly connected to the inner side of the limiting barrel 10. The connecting pipe 11 is fixedly connected to the upper end of the buffer tank outer shell 1, and the inner cavity of the connecting pipe 11 is connected to the inner cavity of the buffer tank outer shell 1. A venting head 13 is fixedly connected to the upper end of the connecting pipe 11. Multiple venting holes 14 are opened on the outer side of the venting head 13. A sealing cover 16 is sleeved on the outer side of the venting head 13. The sealing cover 16 and the venting head 13 are designed to be sealed. A breathable ring-shaped limiting plate 15 is fixedly connected to the lower end of the sealing cover 16. An insertion groove 12 is formed between the limiting barrel 10 and the connecting pipe 11. The breathable ring-shaped limiting plate 15 is inserted into the inner side of the insertion groove 12.

[0025] Specifically, the liquid first enters the interior of the buffer tank shell 1 through the inlet 2. When the liquid enters, it will impact the buffer plate 8 with the through hole 9, so that the flow rate and impact force are buffered and dispersed, thus protecting the tank. During normal operation, the sealing cover 16 is tightly fitted on the vent head 13 and inserted into the inner side of the insertion groove 12 through the vent ring type limiting plate 15, thereby ensuring the sealing and causing the gas inside the tank to be compressed to buffer and maintain the pressure.

[0026] Preferably, two connecting plates 17 are fixedly connected to the outer side of the sealing cover 16. The lower ends of the two connecting plates 17 are fixedly connected to telescopic tubes 22. The lower ends of the two telescopic tubes 22 are fixedly connected to the outer shell 1 of the buffer tank. The upper ends of the two connecting plates 17 are provided with elastic pressing components. The elastic pressing components include telescopic rods 18. The upper and lower ends of the telescopic rods 18 are fixedly connected to the pressure relief outer shell 6 and the connecting plates 17, respectively. A strong spring 19 is sleeved on the outer side of the telescopic rods 18. The upper and lower ends of the strong springs 19 are also fixedly connected to the pressure relief outer shell 6 and the connecting plates 17, respectively. A slider 20 is fixedly connected to the outer side of the two connecting plates 17. Two sliding blocks 21 corresponding to the sliders 20 are fixedly connected to the inner wall of the pressure relief outer shell 6. The sliders 20 are slidably connected to the inner side of the sliding blocks 21.

[0027] Specifically, when the pressure inside the tank rises abnormally, the compressed gas will stretch and impact the corresponding connecting plate 17 through the two telescopic tubes 22, overcoming the spring force and causing it to move upward. At this time, the slider 20 slides in the sliding block 21, which can improve the stability of the connecting plate 17 when it is on top. The rise of the connecting plate 17 will drive the sealing cover 16 and the vent ring-shaped limiting plate 15 to move upward, thereby exposing the vent hole 14 for venting. Then, the gas is discharged through the exhaust head 7 to achieve pressure relief. After the pressure returns to normal, the spring force causes the sealing cover 16 to reset, thus sealing the outer shell 1 of the buffer tank.

[0028] In this embodiment, two support legs 4 are fixedly connected to the lower end of the buffer tank outer shell 1. The two support legs 4 are respectively located at the front and rear ends of the drain pipe 3. An alarm 5 is installed at the upper end of the buffer tank outer shell 1. The alarm 5 is located at the rear end of the exhaust head 7.

[0029] Specifically, if the pressure exceeds the limit, alarm 5 will sound an alarm to remind the operator to take appropriate measures in time to ensure the safe operation of the buffer tank. More specifically, after a period of use, some impurities and sediments may accumulate inside the tank. At this time, these impurities and sediments can be discharged from the tank by opening the drain pipe 3 to ensure the normal operation of the buffer tank and the quality of the internal liquid. The design of two support legs 4 can realize the stability of the buffer tank during operation and can also keep the buffer tank a certain distance off the ground to prevent moisture from causing corrosion of the buffer tank.

[0030] It should be noted that this utility model is a buffer tank with a pressure relief structure. The liquid first enters the interior of the buffer tank shell 1 through the inlet 2. When the liquid enters, it will impact the buffer plate 8 with through holes 9, which will buffer and disperse the flow rate and impact force, thus protecting the tank. During normal operation, the strong spring 19 of the elastic pressing component will make the sealing cover 16 tightly fit on the vent head 13, and the vent ring-shaped limiting plate 15 is inserted into the inner side of the insertion groove 12, thereby ensuring the sealing performance and promoting the compression of the gas inside the tank. When the pressure inside the tank rises abnormally, the compressed gas will stretch the two telescopic tubes 22 and impact the corresponding connecting plate 17, overcoming the spring force and moving it upward. At this time, it cooperates with the slider 20 in the sliding groove block 21. The internal sliding mechanism improves the stability of the connecting plate 17 when it is on top. The rise of the connecting plate 17 will cause the sealing cover 16 and the vent ring-shaped limiting plate 15 to move upward, thereby exposing the vent hole 14 for venting. The vent is then discharged through the exhaust head 7 to relieve pressure. After the pressure returns to normal, the spring force causes the sealing cover 16 to reset, thus sealing the outer shell 1 of the buffer tank. If the pressure exceeds the limit, the alarm 5 will sound an alarm to remind the operator to take appropriate measures in time to ensure the safe operation of the buffer tank. After a period of use, some impurities and sediments may accumulate inside the tank. At this time, these impurities and sediments can be discharged from the tank by opening the drain pipe 3 to ensure the normal operation of the buffer tank and the quality of the internal liquid.
