Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of carbon dioxide production equipment, and more specifically, to a carbon dioxide cylinder fixing device. Background Technology
[0002] Pressure swing adsorption (PSA) is a highly efficient gas separation technology used to extract high-purity carbon dioxide from mixed exhaust gases. In industrial production, a mixed gas containing carbon dioxide is compressed to a certain pressure; then, the compressed gas is fed into a PSA unit. This unit is filled with specific adsorbents, such as activated carbon and molecular sieves, which selectively adsorb carbon dioxide. Under high pressure, carbon dioxide is adsorbed onto the surface of the adsorbent, while other impurity gases are discharged through the adsorption bed. When the adsorbent reaches saturation, the pressure is reduced, causing the carbon dioxide to desorb from the adsorbent surface, thus purifying the carbon dioxide. The desorbed carbon dioxide undergoes further purification and drying to remove residual impurities and moisture, ultimately yielding a high-purity carbon dioxide product. PSA technology offers advantages such as simple operation, low energy consumption, high product purity, and environmental friendliness, and is widely used in chemical, food, pharmaceutical, and environmental protection fields.
[0003] In the production of carbon dioxide, to ensure its purity, it is usually necessary to sample and test the gaseous products generated in each process step. Seamless steel cylinders are typically used for gas storage during sampling, and existing seamless steel cylinders are usually dual-valve cylinders. Dual-valve cylinders are designed with two valves, one for inlet and one for outlet, allowing for more flexible control of gas flow in different application scenarios. However, due to the special structure of dual-valve cylinders, they are prone to rolling during gas testing, potentially leading to safety accidents. Therefore, it is necessary to propose a device for securing and holding dual-valve cylinders. Utility Model Content

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0031] Reference Figures 1 to 4 As shown, this utility model discloses a carbon dioxide cylinder fixing device, including a support structure 100 and an anti-slip structure 200. The support structure 100 is provided with a support plate 110, and the two sides of the support plate 110 are bent upwards to form two support portions 120. The upper ends of the two support portions 120 are respectively provided with U-shaped slots 121; the centers of the two U-shaped slots 121 are collinear. The anti-slip structure 200 and the support plate 110 are detachably connected, and the anti-slip structure 200 is used to fix the support structure 100 to a workbench. Specifically, in this embodiment, the two sides of the support plate 110 are bent upwards to form two support portions 120, and the upper ends of the support portions 120 are provided with U-shaped slots 121, with the centers of the two U-shaped slots 121 being collinear. When a dual-valve cylinder 300 is placed, the bottlenecks on both sides of the dual-valve cylinder 300 can be precisely placed on these two U-shaped slots 121. Because the U-shaped slot 121 provides a certain degree of enclosure around the neck of the cylinder, and the positional relationship between the two U-shaped slots 121 ensures that the cylinder remains horizontal, thus achieving horizontal fixation of the dual-valve cylinder 300. This design utilizes the cooperation between the U-shaped slot 121 and the neck of the dual-valve cylinder 300 to physically restrict the cylinder's horizontal movement and rotation, maintaining its stable horizontal posture. The anti-slip structure 200 is detachably connected to the support plate 110. The function of the anti-slip structure 200 is to fix the support structure 100 to the workbench. The anti-slip structure 200 prevents the support structure 100 from slipping on the workbench by generating sufficient friction with the workbench surface or by using specific connection methods such as clamping or adsorption. This securely fixes the entire support structure 100 to the workbench, preventing it from sliding due to external forces such as equipment vibration or personnel collisions, thereby ensuring that the dual-valve cylinder 300 fixed to the support structure 100 is not affected by the slippage of the support structure 100. A U-shaped slot 121 is used to hold the neck of the dual-valve gas cylinder 300. The U-shaped slot 121 provides good positioning and constraint for the cylinder neck. Compared with simple planar supports, the U-shaped slot 121 can better limit the horizontal swaying and rolling of the cylinder, keeping the cylinder in a stable horizontal position on the support structure 100. It is also convenient to place and remove, and offers good safety.
[0032] In some embodiments of this utility model, the support plate 110 is recessed downward to form a mounting portion 111, and the anti-slip structure 200 is disposed on the mounting portion 111. This structural design reduces the machining precision required for the support plate 110. Specifically, during machining, only the flatness of a local area of the mounting portion 111 on the support plate 110 needs to be ensured, without considering the overall flatness of the support plate 110. Furthermore, the mounting portion 111 also improves the structural strength of the support plate 110. Moreover, the anti-slip structure 200, disposed on the mounting portion 111, more effectively provides anti-slip protection. The mounting portion 111 provides a stable support base for the anti-slip structure 200, allowing the anti-slip structure 200 to better contact the workbench surface and generate friction.
[0033] In some embodiments of this utility model, the support structure 100 is integrally formed from an aluminum alloy plate. Aluminum alloy has the characteristics of low density and high strength. The low density makes the entire support structure 100 lighter, which is convenient for handling and installation. In actual use scenarios, it reduces the labor intensity of operators and is also beneficial for use in some work environments with weight requirements, such as places where frequent movement of equipment is required. At the same time, the high strength ensures that the support structure 100 can withstand the weight of the double-valve cylinder 300 and the external forces that may be subjected to during use, without easily deforming or being damaged, thus ensuring stable support for the double-valve cylinder 300. The integral forming process involves directly forming the required shape of the support structure 100 from a single piece of aluminum alloy plate through processes such as cutting, bending, and punching, including a support plate 110, support parts 120 bent upwards on both sides, and possibly downwardly recessed mounting parts 111, etc. Integral forming avoids connection problems caused by splicing multiple parts, such as weld defects at welding points and loosening at riveting points. The one-piece molding structure has better overall integrity and higher connection strength between parts, which can better distribute the stress and improve the overall stability and reliability of the support structure 100. For example, when bearing the weight of the dual-valve cylinder 300, the one-piece molding structure can evenly distribute the pressure across the entire support structure 100, reducing local stress concentration.
[0034] In some embodiments of this utility model, a plurality of first process grooves 122 are provided on the support portion 120, and the plurality of first process grooves 122 are linearly arranged along the width direction of the support portion 120. The design of the first process grooves 122 can improve the structural strength of the support portion 120. In this embodiment, since the support portion 120 is made of 2mm aluminum alloy plate, the structural strength of the support portion 120 can be improved by stamping the first process grooves 122 on the support portion 120.
[0035] In some embodiments of this utility model, a plurality of second process grooves 112 are provided on the support plate 110; the plurality of second process grooves 112 are linearly arranged along the width direction of the support plate 110. The design of the first process groove 122 can improve the structural strength of the support plate 110. In this embodiment, since the support part 120 is made of 2mm aluminum alloy plate, the structural strength of the support plate 110 can be improved by stamping the second process grooves 112 on the support plate 110.
[0036] In some embodiments of this utility model, an anti-slip sleeve 113 is provided on the U-shaped slot 121, and the anti-slip sleeve is made of an elastic structure. In this embodiment, the anti-slip sleeve 113 on the U-shaped slot 121 increases the contact area of the neck of the double-valve cylinder 300, thereby improving the stability of the placement of the double-valve cylinder 300. In addition, it can also prevent the neck of the double-valve cylinder 300 from directly contacting the U-shaped slot 121 made of aluminum alloy, thus preventing wear on the neck of the double-valve cylinder 300. In this embodiment, the anti-slip sleeve can be made of rubber or silicone.
[0037] In some embodiments of this utility model, the support structure 100 further includes a reinforcing rod 130, the two ends of which abut against two support portions 120 respectively; and are fixed to the support plate 110 by a first bolt 131. The two ends of the reinforcing rod 130 abut against two support portions 120 respectively, and are fixed to the support plate 110 by the first bolt 131, thus connecting the two support portions 120 and the support plate 110 into a more compact whole. Mechanically, this connection method enables the entire support structure 100 to work collaboratively under stress. For example, when the dual-valve cylinder 300 is placed on the support portion 120 and the support portion 120 is under pressure, the reinforcing rod 130 can transfer the force of one support portion 120 to the other support portion 120, and at the same time, it can also distribute some of the force to the support plate 110, so that the entire support structure 100 shares the load, avoiding excessive local stress on a single support portion 120 or support plate 110, thereby improving the overall load-bearing capacity of the structure.
[0038] In some embodiments of this utility model, the anti-slip structure 200 includes a second bolt 210, a mounting base 220, an anti-slip pad 230, an elastic washer 240, and a nut 250. The anti-slip pad 230 abuts against the mounting base 220. The mounting base 220 and the elastic washer 240 abut against the support plate 110 on both sides of the support plate 110, respectively. The second bolt 210 passes sequentially through the anti-slip pad 230, the mounting base 220, the support plate 110, and the elastic washer 240, and is threadedly connected to the nut 250. The core of the anti-slip structure 200 is the anti-slip pad 230, which abuts against the mounting base 220 and ultimately contacts the workbench surface. The anti-slip pad 230 is typically made of a material with a high coefficient of friction, such as rubber. When the second bolt 210 passes through the anti-slip pad 230, mounting base 220, support plate 110, and elastic washer 240 in sequence and is threadedly connected to the nut 250, the tightening process of the nut 250 generates axial tension, causing the anti-slip pad 230 to press tightly against the worktable surface. This pressure causes a large frictional force between the anti-slip pad 230 and the worktable surface, effectively preventing the support structure 100 from sliding on the worktable. The mounting base 220 and elastic washer 240 are located on both sides of the support plate 110, abutting against the support plate 110, which provides a stable connection. The mounting base 220 provides a foundation for the installation and support of the anti-slip pad 230, ensuring that the anti-slip pad 230 can accurately contact the worktable surface and function. The elastic washer 240 acts as a buffer and compensation when the nut 250 is tightened; it can absorb some of the stress generated by the tightening force, preventing the support plate 110 from deforming or being damaged due to over-tightening. At the same time, the elasticity of the elastic pad 240 can also adapt to the unevenness of the work surface to a certain extent, ensuring that the entire anti-slip structure 200 fits tightly with the work surface, further enhancing the anti-slip effect.
[0039] In some embodiments of this invention, the anti-slip mat 230 is a rubber mat. Rubber materials naturally have a high coefficient of friction. This is because rubber molecular chains have great flexibility and viscosity. When the rubber mat comes into contact with the work surface, the rubber molecular chains can interlock with the microscopic unevenness of the work surface, forming numerous tiny contact points. These contact points generate significant friction under pressure, thereby effectively preventing the support structure 100 from sliding.
[0040] In some embodiments of this invention, the anti-slip mat 230 is a suction cup. The suction cup, acting as the anti-slip mat 230, utilizes the principle of vacuum adsorption. When the suction cup is in close contact with the work surface, air inside the suction cup is expelled by compression, creating a relatively low-pressure environment inside the suction cup, while the external atmospheric pressure is higher. Under this pressure difference, the suction cup is pressed tightly against the work surface, generating a strong adsorption force, thereby effectively preventing the support structure 100 from sliding.
[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
