Technical Field
[0001] This utility model relates to the technical field of gas storage and buffering equipment, specifically a multi-cavity gas buffer tank. Background Technology
[0002] In industrial production, gas delivery systems often experience fluctuations in gas source pressure and sudden changes in flow rate, leading to unstable operation of downstream equipment, affecting product quality, and even posing safety hazards. Traditional gas buffer tanks are mostly single-chamber structures with limited buffering capacity and low pressure regulation accuracy, making it difficult to cope with the needs of multiple gas sources or multiple users under complex operating conditions.
[0003] Existing buffer devices have simple buffer structure designs, often using a single chamber for direct gas storage. This easily leads to turbulence when gas enters, resulting in large pressure fluctuations and poor buffering performance. Furthermore, the lack of an effective independent control and monitoring mechanism prevents precise adjustment for different gases or pressure requirements, and the chamber is prone to liquid accumulation and corrosion, shortening the equipment's lifespan.
[0004] Therefore, developing a gas buffer device with independent control of multiple cavities, a high-efficiency buffer structure, and intelligent monitoring functions is the key to solving the above problems. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides a multi-cavity gas buffer tank. The equipment, through its independent multi-cavity design and multi-level buffer structure, can effectively reduce pressure fluctuations during gas transportation. At the same time, it is equipped with intelligent detection and control components to ensure the safety and reliability of the gas processing process and meet the gas buffering requirements under different working conditions.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-cavity gas buffer tank, comprising a tank body, wherein the interior of the tank body is divided into multiple independent buffer cavities by several horizontally arranged partitions, the partitions being sealed to the inner wall of the tank body, and each buffer cavity having an independent air inlet assembly and an air outlet assembly on its side wall, the air inlet assembly comprising an air inlet pipe and an air inlet solenoid valve disposed on the air inlet pipe, the air outlet assembly comprising an air outlet pipe and an air outlet solenoid valve disposed on the air outlet pipe, and each buffer cavity having a buffer structure inside, the air inlet end of the buffer structure being connected to the air inlet assembly.
[0007] Preferably, the buffer structure includes a first buffer tube installed at the air outlet end of the air inlet pipe. The first buffer tube is hexagonal in shape, and a second buffer tube with a hexagonal structure is provided inside the first buffer tube. The first buffer tube and the second buffer tube are connected by a connecting pipe, and multiple equidistant air vents are provided on the surface of both the first buffer tube and the second buffer tube. The air vents are provided on the side surfaces of the first buffer tube and the second buffer tube.
[0008] Preferably, each of the buffer cavities is provided with a pressure detection component, which is a pressure sensor, with the detection end of the pressure sensor extending into the buffer cavity and the signal output end of the pressure sensor extending to the outside of the tank.
[0009] Preferably, the upper and lower surfaces of the partition are both tapered, and each of the buffer cavities is fitted with a drain pipe, the surface of which is equipped with a control valve.
[0010] Preferably, a plurality of buffer components are installed inside the air inlet port of the first buffer pipe. The buffer component includes a fixed seat installed on the inner wall of the air inlet port of the first buffer pipe. A buffer rod is rotatably connected to the surface of the fixed seat via a rotating shaft. A retaining spring is provided at the hinge position between the buffer rod and the fixed seat. A plurality of wind deflectors are installed on both sides of the surface of the buffer rod.
[0011] Preferably, the plurality of buffer components are arranged symmetrically in pairs, and the two sets of buffer components are not on the same horizontal plane but are arranged in a cross shape.
[0012] Preferably, the inner wall of the buffer cavity is coated with an anti-corrosion layer, which is a polytetrafluoroethylene coating or an epoxy resin coating.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention utilizes a multi-stage buffer structure composed of double-layer hexagonal buffer tubes and cross-shaped buffer components to significantly reduce gas flow rate and pressure fluctuations, minimize turbulence, and improve gas stability. The multi-chamber independent design, coupled with dedicated inlet and outlet components, allows for simultaneous processing of different types and pressure requirements of gas, or individual gas supply to multiple downstream devices, adapting to diverse operating conditions and offering strong flexibility. Each chamber is equipped with a pressure sensor, which, combined with a solenoid valve, enables real-time pressure monitoring and automatic adjustment. It provides rapid response in case of overpressure, enhancing operational safety and ensuring intelligent, safe, and controllable operation. The anti-corrosion layer on the inner wall of the chamber effectively resists corrosion, while the conical baffle and drain pipe design facilitates the drainage of accumulated liquid, reducing chamber wear, lowering maintenance costs, and extending equipment life. Independent chambers can be started and stopped independently, reducing energy waste. Combined with precise pressure control, this ensures efficient and stable operation of downstream equipment, improving overall production efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a multi-cavity gas buffer tank, including a tank body 1. The tank body 1 is divided into multiple independent buffer cavities 3 by several horizontally arranged partitions 2. The partitions 2 are sealed to the inner wall of the tank body 1. Each buffer cavity 3 is provided with an independent air inlet assembly 4 and an air outlet assembly 5 on its side wall. The air inlet assembly 4 includes an air inlet pipe 41 and an air inlet solenoid valve 42 provided on the air inlet pipe 41. The air outlet assembly 5 includes an air outlet pipe 51 and an air outlet solenoid valve 52 provided on the air outlet pipe 51. Each buffer cavity 3 is provided with a buffer structure 7. The air inlet end of the buffer structure 7 is connected to the air inlet assembly 4. Each buffer cavity 3 is equipped with an independent air inlet assembly 4 on its side wall, including an air inlet pipe 41 and an air inlet solenoid valve 42. The intake pipe 41 is responsible for delivering external gas to the buffer chamber 3. The intake solenoid valve 42 can precisely control the opening and closing of the intake passage. Combined with subsequent pressure detection signals, it realizes intelligent adjustment of the intake volume. The exhaust component 5 corresponds one-to-one with the intake component and consists of the exhaust pipe 51 and the exhaust solenoid valve 52. The exhaust pipe 51 delivers the buffered gas to the downstream equipment. The exhaust solenoid valve 52 controls the opening and closing of the exhaust passage, and works with the intake component 4 to realize coordinated control of the gas pressure and output flow rate in the buffer chamber 3.
[0023] It should be noted that: Tank 1, as the main supporting structure of the equipment, is made of high-strength metal material, which has good pressure resistance and impact resistance, providing a stable installation and operating environment for internal components.
[0024] It should be noted that several baffles 2 are installed horizontally along the inside of the tank 1, and are sealed to the inner wall of the tank 1 to ensure that each space is independently sealed after separation. The upper and lower surfaces of the baffles 2 are designed with a conical structure. This structure can guide the condensate that may be generated in the buffer chamber 3 to the bottom of the chamber, which is convenient for subsequent discharge and avoids liquid retention that may cause corrosion to the equipment or affect the gas buffering effect.
[0025] It should be noted that the buffer chamber 3 is divided into multiple independent units by the partition 2. Each chamber is an independent gas buffer space and can operate individually or in conjunction with other units according to actual needs. The inner wall of the chamber is coated with an anti-corrosion layer, which can be made of polytetrafluoroethylene or epoxy resin, effectively resisting the erosion of corrosive components in the gas and extending the service life of the equipment.
[0026] It should be noted that each buffer chamber 3 is equipped with a pressure detection component 6, which uses a high-precision pressure sensor. The detection end of the pressure sensor extends directly into the interior of the buffer chamber 3, allowing for real-time acquisition of gas pressure data within the chamber 3; the signal output end extends to the outside of the tank 1, connecting to an external control system, enabling real-time transmission of pressure signals to the control terminal. This facilitates monitoring of the pressure status of each chamber by operators. When the pressure exceeds the preset range, an alarm can be triggered or the inlet and outlet solenoid valves 52 can be automatically adjusted to ensure safe operation of the equipment.
[0027] like Figures 1 to 5As shown, the buffer structure 7 is installed inside each buffer cavity 3. Its air inlet end is connected to the air outlet end of the air inlet pipe 41 of the air inlet assembly 4. It is used to perform multi-stage buffering on the gas entering the cavity, reducing gas flow rate and pressure fluctuations. The buffer structure 7 includes a first buffer tube 71 and a second buffer tube 72, both of which are hexagonal in design. The first buffer tube 71 is sleeved on the outer ring of the second buffer tube 72, and the two are connected by a connecting pipe to form a double-layer buffer space. The side surfaces of the first buffer tube 71 and the second buffer tube 72 are provided with multiple equidistant vent holes 73. After the gas enters the first buffer tube 71, part of it enters the buffer cavity 3 directly through the vent holes 73 on its surface, and the other part enters the second buffer tube 72 through the connecting pipe, and then exits through the vent holes 73 of the second buffer tube 72. The double-layer dispersion achieves initial buffering and works in conjunction with the buffer component 74. The buffer component 74 is installed inside the air inlet port of the first buffer tube 71 and consists of a fixed base 741, a buffer rod 742, and a baffle plate 743. The fixed base 741 is fixed to the inner wall of the air inlet port of the first buffer tube 71. The buffer rod 742 is rotatably connected to the fixed base 741 via a rotating shaft, and a retaining spring is provided at the hinge position. The retaining spring can adjust the rotation angle of the buffer rod 742 according to the gas pressure change. Multiple baffles 743 are installed on both sides of the surface of the buffer rod 742. When gas enters, the baffles 743 can block and divert the gas, further reducing the gas flow rate. The multiple buffer components 74 are arranged symmetrically in pairs, and the two sets of buffer components 74 are not on the same horizontal plane, but in a cross-shaped layout to ensure that the gas can be uniformly buffered when it enters from different directions.
[0028] Working principle and process: Intake stage: External gas enters the buffer chamber 3 through the intake pipe 41. First, it passes through the buffer component 74 at the intake port of the first buffer pipe 71 and the baffle plate 743 to initially block and divert the gas, reducing the initial flow rate of the gas. Then, the gas enters the first buffer pipe 71. Part of it enters the buffer chamber 3 through the vent hole 73 of the first buffer pipe 71, and the other part enters the second buffer pipe 72 through the connecting pipe. Then, it is dispersed into the chamber through the vent hole 73 of the second buffer pipe 72, realizing multi-stage buffering and reducing gas pressure fluctuations.
[0029] Pressure monitoring and control: The pressure sensor detects the gas pressure in the buffer chamber 3 in real time and transmits the signal to the external control system. When the pressure in the chamber is lower than the preset value, the control system controls the intake solenoid valve 42 to open, increasing the intake volume; when the pressure is higher than the preset value, it can control the intake solenoid valve 42 to close or the exhaust solenoid valve 52 to open, adjusting the pressure in the chamber to the normal range.
[0030] Gas discharge and liquid drainage: The buffered gas is delivered to downstream equipment through the gas discharge pipe 51 and the gas discharge solenoid valve 52 to meet production needs; the condensate generated during equipment operation is guided by the conical structure of the partition 2 to the bottom of the cavity, and the operator can periodically open the control valve of the drain pipe 11 to discharge the condensate.
