Description

Technical Field

[0001] This utility model belongs to the technical field of anhydrous dyeing auxiliary equipment, specifically, it relates to a gas cylinder support and a gas filling system. Background Technology

[0002] Supercritical carbon dioxide dyeing is a dyeing process that uses supercritical carbon dioxide as a medium. Under high temperature and high pressure (exceeding the critical pressure of carbon dioxide), carbon dioxide is converted into a supercritical state, dissolving the dye. Through the extremely strong penetrability of supercritical carbon dioxide, dye molecules are carried into the fabric for dyeing. After dyeing, the pressure is reduced, and the carbon dioxide turns into a gaseous state and separates from the dye. No water washing is required, making it an environmentally friendly dyeing process.

[0003] During the dyeing process, leaks in valves, joints, and pumps can reduce the amount of carbon dioxide stored in the tanks. Since some tanks are small, they cannot be replenished via tank trucks and must be filled using gas cylinders. However, manually turning the cylinders during filling is extremely inconvenient, increasing labor intensity and reducing overall filling efficiency. Furthermore, temperature and pressure variations during filling cause unstable carbon dioxide flow, affecting filling efficiency and increasing pump consumption.

[0004] Therefore, given the inconvenience of manually inverting gas cylinders and the instability of the carbon dioxide gas filling process, which affects the gas filling efficiency, a more reasonable technical solution is needed to address the problems existing in the current technology. Utility Model Content

[0005] The purpose of this invention is to provide a gas cylinder support and a gas filling system to solve the problems of inconvenience in manually turning gas cylinders and instability in the carbon dioxide gas filling process in the prior art, which affect the gas filling efficiency.

[0006] To achieve the above objectives, this utility model provides a gas cylinder support, including a base, a limiting frame, a baffle, a side support, and a bottom support. The limiting frame is rotatably connected to the base and has a cavity for accommodating the gas cylinder. The side support is disposed in the cavity, and its two ends are respectively fixedly connected to the limiting frame. An arc-shaped groove is formed on the side support to fit against the side wall of the gas cylinder.

[0007] The limiting frame has a bottom end and a top end; the bottom support is disposed at the bottom end of the limiting frame to constrain the bottom of the gas cylinder.

[0008] The baffle is located at the top of the limiting frame to constrain the bottleneck of the gas cylinder.

[0009] Alternatively, the limiting frame may be provided with a clamp for holding the gas cylinder.

[0010] Alternatively, the gas cylinder support may further include a limiting rod connected to the support, wherein the limiting rod can press against the base when the limiting frame rotates relative to the base.

[0011] Optionally, two limiting rods are provided, and they are respectively disposed on both sides of the bracket.

[0012] Optionally, both the limiting frame and the base are configured as hollow frames.

[0013] Alternatively, the limiting frame is provided with a positioning hole adapted to the fastener, and the baffle is provided with a through hole adapted to the fastener. The fastener passes through the through hole and the positioning hole in sequence to detachably connect the baffle to the limiting frame.

[0014] Optionally, multiple positioning holes are provided and evenly spaced along the length direction of the limiting frame, wherein the length direction is parallel to the axial direction of the gas cylinder.

[0015] A gas filling system includes a vacuum pump, a three-way valve, a storage tank, and a gas cylinder support. A gas cylinder containing gas is mounted on the gas cylinder support. The three-way valve has a first port, a second port, and a third port. The first port is connected to the gas cylinder via a gas inlet pipe; the second port is connected to the storage tank via a balance pipe; and the third port is connected to the storage tank via a vacuum pipe.

[0016] The air passage is equipped with a conversion connector, and a pressure detector is installed on the air passage between the conversion connector and the three-way valve.

[0017] The balance pipe is equipped with a first control valve, the air extraction pipe is equipped with a second control valve and the air extraction pump, and the second control valve is located between the three-way valve and the air extraction pump.

[0018] Alternatively, the gas injection system may further include a controller, which is communicatively connected to the pressure detector, the vacuum pump, the first control valve, and the second control valve. The control valve controls the vacuum pump, the first control valve, and the second control valve to perform corresponding actions based on the current pressure information of the gas passage detected by the pressure detector.

[0019] Optionally, the inlet pipe of the storage tank is equipped with a condensation device;

[0020] And / or, the air passage is further provided with a filter, which is located between the pressure detector and the three-way valve.

[0021] Using the above technical solution, the operator can rotate the limiting frame relative to the base according to the gas volume in the cylinder. When the gas volume is sufficient, keeping the limiting frame vertical ensures the cylinder is placed upright, guaranteeing stable gas output. As the gas volume decreases, the limiting frame can be gradually rotated to adjust the cylinder's angle, allowing for smooth gas delivery. The rotating design of the limiting frame allows for easy adjustment of the cylinder's angle to adapt to different operational needs. Adjusting the cylinder's angle optimizes gas delivery efficiency, especially when the gas volume decreases, ensuring smooth and continuous gas delivery.

[0022] By tilting the gas cylinder and balancing the pressure, liquid carbon dioxide can smoothly enter the storage tank, greatly improving filling efficiency. During the liquid carbon dioxide transfer phase, gravity and pressure difference are primarily relied upon, reducing the energy consumption of the pump. Based on the pressure detector, the pressure difference between the gas cylinder and the storage tank can be monitored in real time, ensuring operational safety. Thus, a highly efficient, energy-saving, safe, and convenient carbon dioxide filling operation is achieved.

Detailed Implementation

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] According to a specific embodiment of this disclosure, a gas cylinder support is provided, wherein... Figures 1 to 4 One specific implementation is shown.

[0033] Specifically, see Figures 1 to 4 As shown, the gas cylinder support includes a base 11, a limiting frame 12, a baffle 13, a side support 14, and a bottom support 15. The limiting frame 12 is rotatably connected to the base 11 and has a cavity for accommodating the gas cylinder 2. The side support 14 is disposed in the cavity, and its two ends are fixedly connected to the limiting frame 12. An arc-shaped groove is formed on the side support 14 to fit the side wall of the gas cylinder 2. The limiting frame 12 has a bottom end and a top end. The bottom support 15 is disposed at the bottom end of the limiting frame 12 to constrain the bottom of the gas cylinder 2. The baffle 13 is disposed at the top end of the limiting frame 12 to constrain the neck of the gas cylinder 2.

[0034] During the operation of the gas cylinder support 1: First, the gas cylinder 2 is placed on the limiting frame 12. Then, the limiting frame 12 is pushed according to the gas volume of the gas cylinder 2, causing it to flip relative to the base 11, thereby adjusting the position of the gas cylinder 2. This saves effort and makes it easy for operators to adjust the position of the gas cylinder 2. Specifically, when the gas volume in the gas cylinder 2 is sufficient, the limiting frame 12 can be set vertically relative to the base 11, keeping the gas cylinder 2 in a vertical position for stable carbon dioxide output. As the carbon dioxide volume decreases, the limiting frame 12 can be flipped, allowing the carbon dioxide to be smoothly discharged, ultimately completing the flow of carbon dioxide from the gas cylinder 2 to the storage tank 5.

[0035] The base 11 serves as the supporting part of the entire bracket and is the fixed foundation for all other components. The limiting frame 12 is rotatably connected to the base 11 and is designed with a cavity to accommodate the gas cylinder 2. This allows the limiting frame 12 to be rotated as needed, thereby adjusting the angle of the gas cylinder 2. An arc-shaped groove within the cavity of the limiting frame 12 conforms to the side wall of the gas cylinder 2, providing support and stability. The bottom support 15 is located at the bottom of the limiting frame 12 and is used to restrain the bottom of the gas cylinder 2, preventing it from sliding or tipping over during movement or operation. The baffle 13 is located at the top of the limiting frame 12 and is used to restrain the neck of the gas cylinder 2, further limiting its position. When the gas cylinder 2 is placed in the cavity of the limiting frame 12, the bottom support 15, side supports 14, and baffle 13 respectively support the bottom, side wall, and neck of the gas cylinder 2. Therefore, the combination design of the base support 15, the side support 14 and the baffle 13 ensures the stability of the gas cylinder 2 during movement and operation, and prevents the gas cylinder 2 from tipping over or sliding.

[0036] Using the above technical solution, the operator can rotate the limiting frame 12 relative to the base 11 according to the gas volume in the gas cylinder 2. When the gas volume is sufficient, the limiting frame 12 is kept vertical, ensuring the gas cylinder 2 is placed vertically and a stable gas output is guaranteed. As the gas volume decreases, the limiting frame 12 can be gradually rotated to adjust the angle of the gas cylinder 2, allowing the gas to be discharged smoothly. The rotating design of the limiting frame 12 allows for easy adjustment of the angle of the gas cylinder 2 to adapt to different operational needs. By adjusting the angle of the gas cylinder 2, the gas discharge efficiency can be optimized, especially when the gas volume decreases, ensuring a smooth and continuous gas discharge.

[0037] Furthermore, the limiting frame 12 is equipped with a clamp 16 for holding the gas cylinder 2. The clamp 16 is designed to wrap around and secure the gas cylinder 2, providing a tighter fixation and preventing unnecessary movement or shaking of the gas cylinder 2 during operation. This improves the safety of the gas cylinder support 1 and reduces the risk of the gas cylinder 2 falling off or tipping over.

[0038] In addition, clamp 16 should be made of a strong and corrosion-resistant material to ensure that it can withstand the weight of gas cylinder 2 and the harsh environments it may encounter. The materials used include, but are not limited to, stainless steel, alloy steel, or high-strength plastics.

[0039] It should be noted that the clamp 16 is typically designed to be adjustable or replaceable to accommodate gas cylinders 2 of different sizes and shapes. Specifically, the clamp 16 includes a retaining ring, which is connected by bolts, nuts, or clips to securely fix the gas cylinder 2 to the limiting frame 12.

[0040] In one embodiment provided in this disclosure, the gas cylinder support 1 further includes a limiting rod 17 connected to the support. When the limiting frame 12 rotates relative to the base 11, the limiting rod 17 presses against the base 11. This creates a physical stop structure through the pressure between the limiting rod 17 and the base 11. When the limiting frame 12 rotates relative to the base 11 to a certain angle, the limiting rod 17 touches the base 11 and prevents the limiting frame 12 from rotating further. Thus, even if the operator uses excessive force or operates improperly when adjusting the position of the gas cylinder 2, it can be ensured that the gas cylinder 2 will not detach from the support or collide with the base 11 or the ground due to excessive rotation of the limiting frame 12.

[0041] The presence of the limit rod 17 not only restricts the rotation range of the limit frame 12, but also enhances the stability of the entire gas cylinder support 1 to a certain extent, making the support more stable when bearing the weight of the gas cylinder 2 and the operating force, and reducing the risk of accidents caused by shaking or tilting.

[0042] The limit rod 17 is made of stainless steel to ensure that it can withstand the force generated when the limit frame 12 rotates and maintain a stable shape.

[0043] Furthermore, two limit rods 17 are provided, each located on one side of the bracket. The two limit rods 17, situated on opposite sides of the bracket, form a double-sided support for the limit frame 12, making the limit frame 12 more stable during rotation and less prone to swaying or tilting. In this configuration, even if one limit rod 17 fails for some reason (such as damage or loosening), the other limit rod 17 can still function, preventing the limit frame 12 from rotating beyond its limit and protecting the gas cylinder 2 from impacts.

[0044] In this disclosure, the limiting rod 17 is detachably connected to the limiting frame 12 via a threaded structure, thereby facilitating replacement and maintenance.

[0045] In this disclosure, both the limiting frame 12 and the base 11 are configured as hollow frames. The hollow structure means that while maintaining structural strength, unnecessary material usage is reduced, which helps to lighten the overall weight of the gas cylinder support, facilitating installation, movement, and transportation. In applications requiring frequent movement or adjustment of the gas cylinder 2's position, the lighter weight can significantly improve operational efficiency and reduce labor costs.

[0046] For certain types of gas cylinders (such as high-pressure gas cylinders), excessively high temperatures may affect their performance and safety. The perforated design helps to reduce the temperature inside the support, preventing damage to the gas cylinder due to overheating.

[0047] Meanwhile, the openwork structure allows operators to easily observe the status of gas cylinder 2 and the fixation of the support. Furthermore, the openwork design provides easier access and a wider operating space when cleaning or maintenance is required.

[0048] In this disclosure, anti-rust paint can be sprayed onto the outer surfaces of the base 11 and the limiting frame 12 to extend their service life. In other embodiments, stainless steel can also be used to make the base 11 and the limiting frame 12.

[0049] In one embodiment, the limiting frame 12 has a positioning hole adapted to a fastener, and the baffle 13 has a through hole adapted to a fastener. The fastener passes through the through hole and the positioning hole in sequence to detachably connect the baffle 13 to the limiting frame 12. The fastener (such as a screw or bolt) can easily fix the baffle 13 to the limiting frame 12 by passing through the through hole of the baffle 13 and the positioning hole of the limiting frame 12 in sequence. Similarly, when it is necessary to remove the baffle 13, simply loosen the fastener; no complicated tools or cumbersome operations are required.

[0050] The detachable design allows the baffle 13 to be replaced, adjusted, or cleaned as needed. In different application scenarios, the appropriate baffle 13 material and specifications can be selected according to actual needs to meet specific usage requirements.

[0051] Compared to other connection methods (such as welding, bonding, etc.), fastener connections offer better resistance to loosening. Even when subjected to vibration or impact during use, the fasteners maintain a stable connection, ensuring the firmness between the baffle 13 and the limit bracket 12.

[0052] In practical applications, the appropriate type and specification of fasteners can be selected according to actual needs. For example, in situations where the fasteners need to withstand large external forces, a combination of high-strength bolts and nuts can be selected; in situations where frequent disassembly is required, quick-release screws that are easy to operate can be selected.

[0053] Furthermore, multiple positioning holes are provided and evenly spaced along the length of the limiting frame 12, which is parallel to the axis of the gas cylinder 2. The arrangement of multiple positioning holes allows the baffle 13 to be fixed at multiple points on the limiting frame 12. This multi-point fixing method can more evenly distribute the fixing force and improve the stability and reliability of the connection.

[0054] In addition, when it is necessary to adjust the position of the baffle 13, simply loosen the fasteners and reconnect to the appropriate positioning hole. This quick adjustment method improves work efficiency and flexibility, and by adjusting the installation position of the baffle 13, the gas cylinder 2 can be effectively limited.

[0055] According to embodiments of this disclosure, a gas injection system is provided. Figures 1 to 4 One embodiment is shown.

[0056] The gas filling system includes a vacuum pump 3, a three-way valve 4, a storage tank 5, and the aforementioned gas cylinder support 1. The gas cylinder support 1 holds a gas cylinder 2 containing gas. The three-way valve 4 has a first port, a second port, and a third port. The first port is connected to the gas cylinder 2 via a gas inlet pipe 61; the second port is connected to the storage tank 5 via a balance pipe 62; and the third port is connected to the storage tank 5 via a vacuum pipe 63. The gas inlet pipe 61 is equipped with a conversion connector 71, and a pressure detector 72 is installed on the gas inlet pipe 61 between the conversion connector 71 and the three-way valve 4. The balance pipe 62 is equipped with a first control valve 81, and the vacuum pipe 63 is equipped with a second control valve 82 and the vacuum pump 3. The second control valve 82 is positioned...

[0057] The vacuum pump 3 generates negative pressure to extract gaseous carbon dioxide from cylinder 2 and transfer it to storage tank 5. The three-way valve 4 has three ports (first port, second port, and third port) to control the gas flow between cylinder 2, storage tank 5, and vacuum pump 3. Storage tank 5 stores the carbon dioxide transferred from cylinder 2. Cylinder support 1 secures and tilts cylinder 2, allowing liquid carbon dioxide to drain smoothly.

[0058] The gas transfer pipe 61 connects the gas cylinder 2 and the first port of the three-way valve 4, and is used to transfer liquid and gaseous carbon dioxide. The balancing pipe 62 connects the second port of the three-way valve 4 and the storage tank 5, and is used to balance the pressure between the gas cylinder 2 and the storage tank 5. The suction pipe 63 connects the third port of the three-way valve 4 and the suction pump 3, and is used to extract the remaining gaseous carbon dioxide from the gas cylinder 2 and send it into the storage tank 5.

[0059] The adapter 71 is installed on the gas pipe 61 to connect the gas cylinder 2 and the three-way valve 4, ensuring smooth gas flow.

[0060] Pressure detector 72 is installed on gas pipe 61 to detect the pressure difference between gas cylinder 2 and storage tank 5, ensuring operational safety.

[0061] The first control valve 81 and the second control valve 82 are respectively installed on the balance pipe 62 and the extraction pipe 63, and are used to control the gas flow.

[0062] During operation, first fix cylinder 2 to the support and flip it upside down so that the liquid carbon dioxide is at the bottom of cylinder 2. Connect cylinder 2 to the adapter 71 of three-way valve 4 through gas pipe 61. Open the first control valve 81 on the balance pipe 62. Since the pressure inside cylinder 2 is greater than the pressure in storage tank 5, the liquid carbon dioxide flows into storage tank 5 through balance pipe 62 under the action of gravity and pressure difference. When the pressure on both sides reaches equilibrium, close the first control valve 81. Open the second control valve 82 (i.e., the valve between cylinder 2 and vacuum pump 3). At this time, the negative pressure generated by vacuum pump 3 can draw out the remaining gaseous carbon dioxide in cylinder 2 through vacuum pipe 63 and send it into storage tank 5.

[0063] Through the above technical solution, by flipping gas cylinder 2 and balancing the pressure, liquid carbon dioxide can smoothly enter storage tank 5, greatly improving filling efficiency. During the liquid carbon dioxide transfer stage, gravity and pressure difference are mainly relied upon, reducing the energy consumption of the vacuum pump 3. Based on the setting of pressure detector 72, the pressure difference between gas cylinder 2 and storage tank 5 can be monitored in real time, ensuring operational safety. Thus, a highly efficient, energy-saving, safe, and convenient carbon dioxide filling operation is achieved.

[0064] In one embodiment provided in this disclosure, the gas injection system further includes a controller, which is communicatively connected to the pressure detector 72, the air pump 3, the first control valve 81, and the second control valve 82. The control valves control the air pump 3, the first control valve 81, and the second control valve 82 to perform corresponding actions based on the current pressure information of the gas pipe 61 detected by the pressure detector 72.

[0065] The controller receives current pressure information from pressure detector 72 via a communication interface. This information forms the basis for the controller's decisions. Based on the received pressure information, the controller internally runs a preset control algorithm or logic to determine the current system state and formulate an appropriate control strategy.

[0066] The controller sends control commands to the air pump 3, the first control valve 81 and the second control valve 82 through the communication interface, so that these components perform corresponding operations according to a predetermined sequence of actions.

[0067] With the controller in place, the operation of the gas injection system can reduce manual intervention, greatly improving work efficiency and operational accuracy. The pressure information fed back in real time by the pressure detector 72 allows the controller to continuously monitor the system status. Once an anomaly is detected (such as excessively high or low pressure), immediate measures can be taken to adjust and ensure the safe and stable operation of the system. The controller's decisions based on pressure information are more precise and intelligent, automatically adjusting control strategies according to different system states and needs to achieve a more efficient carbon dioxide injection process.

[0068] It should be noted that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously.

[0069] Furthermore, a condensing device 91 is installed on the inlet pipe of the storage tank 5. By turning on the condensing device 91 (e.g., a chiller) to cool the storage tank 5, the condensing device 91 can effectively absorb the heat inside the storage tank 5, thereby reducing the temperature inside the storage tank 5. This is based on the principle of heat exchange in physics, that is, when two objects at different temperatures come into contact, heat will be transferred from the object with the higher temperature to the object with the lower temperature.

[0070] According to the ideal gas law (PV=nRT), with the amount of gas (n) and the gas constant (R) remaining constant, the pressure (P) of a gas is directly proportional to its absolute temperature (T). Therefore, when the temperature inside storage tank 5 decreases, its internal pressure will also decrease accordingly. This is crucial for the rapid replenishment of carbon dioxide gas, as a lower pressure in storage tank 5 reduces resistance during gas injection and improves replenishment efficiency.

[0071] The reduced pressure inside storage tank 5 reduces resistance during gas injection, allowing more carbon dioxide gas to enter storage tank 5 more quickly under the same injection conditions, thus shortening the replenishment time.

[0072] Before rapidly replenishing carbon dioxide gas, the chiller is first activated to cool storage tank 5. Temperature changes within tank 5 are monitored in real-time using a temperature sensor to ensure the temperature drops below a preset value. Once the temperature in tank 5 reaches the preset value, the gas cylinder connected to tank 5 (i.e., the carbon dioxide source) is opened to begin replenishing the gas. During the replenishment process, pressure and temperature changes within tank 5 are continuously monitored to ensure a smooth process.

[0073] In this disclosure, a filter 92 is also provided on the air passage 61, which is located between the pressure detector 72 and the three-way valve 4. The main function of the filter 92 is to remove impurities such as dust and particulate matter that may be present in the air passage 61, protecting downstream equipment such as the three-way valve 4 from contamination and damage, thereby extending the service life of these components.

[0074] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
