Description

Technical Field

[0001] The utility model relates to the technical field of standard gas cylinder shaking, in particular to a standard gas cylinder shaking device. Background Art

[0002] The standard gas cylinder contains a mixed gas of hydrogen sulfide (H2S), sulfur dioxide (SO2), carbonyl sulfide (COS) with a concentration of CO2, CO, N2, CH4, H2 and other components, and contains methane, ethane, ethylene, propane, propylene, acetylene, isobutane, n-butane and components above C5. With the deepening of analysis and detection work, the number of gas analysis items increases, and it is necessary to take out a standard mixed gas of known concentration from the standard gas cylinder to calibrate the gas chromatograph.

[0003] Due to the different specific gravities of the above-mentioned components, after a long period of quiescence, the heavier gases will settle at the bottom of the standard gas cylinder, while the lighter gases (H2) will float at the top of the cylinder, resulting in uneven distribution of the components. As a result, inaccurate standard gas and poor measurement repeatability often occur during chromatographic calibration. To improve the accuracy of the standard gas, it is common practice to invert the standard gas cylinder upside down for 3 minutes before calibrating the instrument before adding the standard gas for analysis.

[0004] However, since the standard gas cylinder is heavy (5kg), under normal circumstances, one person needs to rotate and invert it continuously for 3 minutes to shake it evenly, which is time-consuming and labor-intensive. In addition, due to the different shaking methods and strengths used by different people, the mixing uniformity of the standard gas components is also different, which will lead to poor shaking effect and bring certain errors to the calibration results of the gas chromatograph.

[0006] In order to solve the above problems, the utility model provides a standard gas cylinder shaking device, which includes a main shell box and a shaking assembly arranged on the main shell box. The shaking assembly includes a base plate rotatably arranged on the main shell box and a driving member for driving the base plate to rotate. The standard gas cylinder is detachably arranged on the base plate and rotates with the rotation of the base plate, wherein at least one driving member is provided at the bottom of both sides of the base plate in the length direction of the standard gas cylinder.

[0010] Furthermore, the base plate has a mounting groove whose shape is adapted to the standard gas cylinder. The standard gas cylinder is arranged in the mounting groove and is limitedly matched with the inner wall of the mounting groove.

[0011] Furthermore, the standard gas cylinder shaking device also includes a limit assembly arranged on the base plate or the main shell box, the limit assembly has a stop end that can span the top opening of the installation groove, and the stop end is fitted with the top of the protruding installation groove of the standard gas cylinder to press the standard gas cylinder into the installation groove.

[0012] Furthermore, the limiting assembly includes an adjusting chain and mounting rods symmetrically distributed on both sides of the mounting groove along the rotation center line direction of the base plate, one end of the adjusting chain is fixedly set on one of the mounting rods, and one section on the other side of the adjusting chain is detachably set on the other mounting rod.

[0013] Furthermore, there are at least two limit assemblies, and the two limit assemblies are spaced apart and distributed on both sides of the rotation center line of the base plate along the extension direction of the installation groove; and / or, the outer periphery of the standard gas cylinder has a card-mounting groove, and the adjustment chain can be at least partially card-mounted in the card-mounting groove.

[0014] Furthermore, the main shell box has an installation cavity for installing the shaking assembly, and the standard gas cylinder shaking device also includes a control module, which is arranged in the installation cavity below the base plate, and the control module is used to control the driving component.

[0015] Furthermore, the control module includes a self-locking button with light, a power supply, a time relay and a solenoid valve electrically connected in sequence. Any driving component is electrically connected to a solenoid valve. Multiple solenoid valves located at the bottom of the same side of the base plate start and stop synchronously, and the self-locking button with light is electrically connected to the leakage protector.

[0016] By applying the technical solution of the utility model, a standard gas cylinder shaking device is provided, which includes a main shell box and a shaking assembly arranged on the main shell box.

The standard gas cylinder is detachably arranged on the base plate and rotates with the rotation of the base plate, wherein at least one driving member is provided at the bottom of both sides of the base plate in the length direction of the standard gas cylinder.

[0017] By adopting this solution, the base plate and the standard gas cylinder arranged on the base plate are driven to shake by the shaking assembly, thereby achieving the shaking of the mixed gas inside the standard gas cylinder.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way serves as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a standard gas cylinder shaking device, which includes a main shell box 10 and a shaking component 20 arranged on the main shell box 10, the shaking component 20 includes a base plate 21 rotatably arranged on the main shell box 10 and a driving member 22 for driving the base plate 21 to rotate, the standard gas cylinder 50 is detachably arranged on the base plate 21 and rotates with the rotation of the base plate 21, wherein at least one driving member 22 is provided at the bottom of both sides of the base plate 21 in the length direction of the standard gas cylinder 50.

[0029] In this embodiment, the shaking drive of the bottom plate 21 and the calibration gas cylinder 50 arranged on the bottom plate 21 is achieved by the shaking component 20, thereby achieving the shaking of the mixed gas inside the calibration gas cylinder 50, and by arranging driving parts 22 at both ends of the calibration gas cylinder 50, it is possible to apply force to the calibration gas cylinder 50 more evenly, thereby avoiding the deviation or instability of the calibration gas cylinder 50 that may be caused by single-point driving, further improving the uniformity of gas shaking and mixing, reducing the risk of gas stratification during the mixing process, ensuring the stability and consistency of the gas composition in the calibration gas cylinder 50, and thus avoiding the frequent occurrence of inaccurate calibration gas and poor measurement repeatability during the chromatographic calibration process, which is beneficial to improving the accuracy of gas analysis and detection. On the other hand, since the standard gas cylinder 50 is a mobile pressure vessel, it is dangerous and may cause safety accidents if it is not operated properly. The shaking device of the standard gas cylinder 50 is helpful to improve the safety of shaking the standard gas cylinder 50, and avoid the situation where different manual shaking strengths and techniques lead to different mixing uniformities of the standard gas components and safety hazards. It is helpful to ensure the uniform shaking of the mixed gas while improving the safety of shaking.

[0030] In this embodiment, a driving member 22 is provided at the bottom of both sides of the bottom plate 21 in the length direction of the calibration gas cylinder 50 .

[0031] Preferably, the driving member 22 is a dual-axis cylinder, which is hingedly or detachably abutted against the bottom of the base plate 21. The use of the dual-axis cylinder not only provides a more stable shaking effect, but also facilitates adjustment of the shaking frequency, amplitude, and force according to specific requirements such as the size and weight of the standard gas cylinder 50, thereby ensuring a uniform shaking effect for standard gas cylinders 50 of different specifications, and is suitable for the uniform shaking pretreatment of standard gas cylinders 50 used in various gas analysis and detection equipment.

[0032] It is understandable that the selection of the driving member 22 can be adaptively adjusted according to actual conditions and is not limited to the dual-axis cylinder provided in this embodiment.

[0033] like Figure 1 As shown, the shaking assembly 20 further includes a bearing rod 23 disposed in the middle area below the bottom plate 21 . The bearing rod 23 is rotatably disposed on the main housing 10 and its axis is the rotation center line of the bottom plate 21 .

[0034] This arrangement is used to achieve the rotational installation of the base plate 21, while ensuring the reliability and stability of the installation of the base plate 21, and to avoid the base plate 21 from falling out or deflecting during the shaking process when the shaking is not restricted. At the same time, this arrangement is also beneficial to reduce noise and vibration during the shaking process.

[0035] Preferably, the bearing rod adopts a high-precision rolling bearing, which is beneficial to reducing friction and wear, thereby extending the service life of the device and reducing operating noise.

[0036] Specifically, the main housing 10 has an installation cavity 101 for installing the shaking assembly 20 , and the outer periphery of the bottom plate 21 is limitedly matched with at least two opposite inner walls of the installation cavity 101 in the direction of the rotation center line of the bottom plate 21 .

[0037] The installation cavity 101 can ensure the limited installation of the base plate 21 and realize the guided limitation of the shaking of the base plate 21, avoiding the situation where the base plate 21 is prone to rotational deviation, which affects the installation and shaking effect of the calibration gas cylinder 50, and ensures the stable installation and shaking drive of the base plate 21 and the calibration gas cylinder 50 set on the base plate 21.

[0038] Preferably, the bottom plate 21 in this embodiment is in a horizontal state and is in position-limiting cooperation with multiple inner walls of the installation cavity 101 .

[0039] Furthermore, the base plate 21 has a mounting groove shaped to match the calibration gas cylinder 50. The calibration gas cylinder 50 is positioned within the mounting groove and engages with the inner wall of the mounting groove. This arrangement allows the calibration gas cylinder 50 to be more securely mounted on the base plate 21, ensuring that the calibration gas cylinder 50 does not shift or tilt relative to the base plate 21 during shaking, thereby ensuring the reliability and stability of the uniform shaking of the calibration gas cylinder 50.

[0040] It is understandable that the shape design of the mounting groove can adapt to the specifications of various standard gas cylinders, so as to improve the applicability of the standard gas cylinder shaking device.

[0041] In this embodiment, the standard gas cylinder shaking device also includes a limit assembly 30 arranged on the base plate 21 or the main shell box 10. The limit assembly 30 has a stop end that can span the top opening of the installation groove. The stop end is fitted with the top of the protruding installation groove of the standard gas cylinder 50 to press the standard gas cylinder 50 into the installation groove.

[0042] With this arrangement, the stop end design of the limit assembly 30 can withstand the lateral force of the calibration gas cylinder 50 during the shaking process, preventing the calibration gas cylinder 50 from separating from the base plate 21 due to inertia. Even when the calibration gas cylinder shaking device moves as a whole or is subjected to slight vibration, and when the base plate 21 and the calibration gas cylinder 50 are shaken and shaken, the calibration gas cylinder 50 can remain stable, further avoiding the calibration gas cylinder 50 from being displaced relative to the base plate 21 during the shaking process and affecting the uniformity of gas mixing, enhancing the fixing effect of the calibration gas cylinder 50, and being conducive to ensuring the reliability and stability of the shaking of the calibration gas cylinder 50 and the continuity and consistency of gas analysis.

[0043] Specifically, the limiting assembly 30 includes an adjusting chain 31 and mounting rods 32 symmetrically distributed on both sides of the mounting groove along the rotation center line direction of the base plate 21. One end of the adjusting chain 31 is fixedly set on one of the mounting rods 32, and one section on the other side of the adjusting chain 31 is detachably set on the other mounting rod 32.

[0044] In this embodiment, before installing the calibration gas cylinder 50, one end of the adjustment chain 31 is fixed on one of the mounting rods 32 and the other end is not installed. After the operator installs the calibration gas cylinder 50 in the mounting groove, the operator tightens the other end of the adjustment chain 31 and presses the calibration gas cylinder 50 into the mounting groove. Then, one section of the other side of the adjustment chain 31 is installed on the other mounting rod 32 to maintain the downward pressure effect of the adjustment chain 31 on the calibration gas cylinder 50.

[0045] With this arrangement, the limit assembly 30 can not only further improve the installation effect of the calibration gas cylinder 50, but also adapt to calibration gas cylinders 50 of different sizes, thereby improving the versatility and flexibility of the calibration gas cylinder shaking device, and is suitable for the shaking needs of calibration gas cylinders 50 of various specifications. The overall length and actual installation length of the adjustment chain 31 (i.e., the length of the adjustment chain 31 between the connection positions with the two mounting rods 32) can be flexibly adjusted, further improving the applicability to calibration gas cylinders 50 of different sizes and the compatibility of the calibration gas cylinder shaking device, and reducing the cost and time required for replacement when facing calibration gas cylinders 50 of different specifications.

[0046] Preferably, there are at least two limit assemblies 30, which are spaced apart on both sides of the rotation centerline of the base plate 21 along the extension direction of the installation groove; and / or, the outer periphery of the calibration gas cylinder 50 has a snap-in groove, and the adjustment chain 31 can be at least partially snap-fitted into the snap-in groove. In this embodiment, the outer periphery of the calibration gas cylinder 50 has a snap-in groove adapted to the adjustment chain 31, and there is at least one limit assemblies 30. Through the cooperation of the limit assemblies 30 and the adjustment chain 31 with the snap-in groove, the calibration gas cylinder 50 is fully fixed during the shaking process, further reducing or eliminating the possibility of the calibration gas cylinder 50 moving along its axial direction, which can significantly enhance the stability of the installation of the calibration gas cylinder 50. Even during high-intensity shaking, the position of the calibration gas cylinder 50 can be maintained, avoiding the calibration gas cylinder 50 from moving or falling out, which can easily lead to reduced shaking effect or safety risks.

[0047] like Figure 1 and Figure 2 As shown, the main shell box 10 has an installation cavity 101 for installing the shaking assembly 20. The standard gas cylinder shaking device also includes a control module 40. The control module 40 is arranged in the installation cavity 101 below the base plate 21. The control module 40 is used to control the driving member 22.

[0048] This arrangement facilitates semi-automatic control of the calibration gas cylinder shaking device, reduces manual intervention, and improves production efficiency and process safety. Furthermore, the control module 40 is disposed within the mounting cavity 101, which facilitates the integration of the calibration gas cylinder shaking device. This not only simplifies the structure of the device but also facilitates operation and maintenance. Specifically, the operator can control the two sets of dual-axis cylinders located at the bottom of both sides of the base plate 21 to alternately extend and retract according to the control module 40, thereby achieving regular shaking of the calibration gas cylinder 50 and ensuring a good shaking effect.

[0049] Specifically, the control module 40 includes a self-locking button 41 with light, a power supply 42, a time relay 43 and a solenoid valve 44 electrically connected in sequence. Any driving component 22 is electrically connected to a solenoid valve 44. Multiple solenoid valves 44 located at the bottom of the same side of the base plate 21 are started and stopped synchronously. The self-locking button 41 with light is electrically connected to the leakage protector 45.

[0050] This arrangement, through precise electrical control design, ensures the safety and reliability of the standard gas cylinder shaking device during the shaking process. Specifically, through the setting of the self-locking button 41 with light, the operator can intuitively understand the working status of the device and whether the standard gas cylinder 50 is correctly locked, which can effectively prevent accidents caused by improper operation. At the same time, the use of the leakage protector 45 further improves electrical safety, ensures the personal safety of the operator and the stable operation of the equipment. On the other hand, by setting the parameters of the time relay 43, it is convenient to control the expansion and contraction and pushing speed of the two groups of double-axis cylinders at the bottom of both sides of the base plate 21, ensure the consistency of the expansion and contraction and pushing speed of the two groups of double-axis cylinders at the bottom of both sides of the base plate 21, and ensure the shaking effect. Among them, a pressure regulating throttle valve is provided on the double-axis cylinder to adjust the expansion and contraction and pushing speed.

[0051] Preferably, in a specific embodiment, the main shell box 10 and the base plate 21 are both made of stainless steel plates, the power supply 42 adopts a 24V DC power supply, the time relay 43 adopts a DC24V time relay, the dual-axis cylinder adopts a TN20*100 dual-axis cylinder, the air pipe adopts an air pipe with a radial dimension of Φ8 and a length of 5 meters, and the solenoid valve 44 adopts a 24V two-position five-way solenoid valve.

[0052] In summary, the present invention provides a standard gas cylinder shaking device, which utilizes the circulation function of the time relay 43 in combination with the solenoid valve 44 and the dual-axis cylinder air line to achieve continuous alternating operation of the dual-axis cylinder at the bottom of the front side of the bottom plate 21 when the dual-axis cylinder at the bottom of the rear side is pushed and extended, and the dual-axis cylinder at the bottom of the front side is extended and extended, thereby pushing the bottom plate 21 up and down and shaking the standard gas cylinder 50 set thereon. Compared with the manual shaking in the prior art, the standard gas cylinder shaking device provided by the present invention can effectively improve the shaking efficiency while reducing labor costs and intensity, and has better effect than manual shaking, improves the accuracy of instrument calibration, and because it is no longer necessary to hold the standard gas cylinder 50 by hand and continuously invert it for mixing, it can improve the safety factor, reduce safety hazards such as breaking the standard gas cylinder pressure reducing valve and possible gas cylinder explosion accidents, and improve the safety of shaking.
