Description

Technical Field

[0001] The utility model belongs to the field of ultrapure mixed gas detection, and in particular relates to an ultrapure mixed gas ratio detection device. Background Art

[0002] Ultrapure mixed gases refer to gases containing two or more ultrapure gases. These gases are a diverse product developed specifically for specific industry applications, with different gas mixtures used in different industries. In manufacturing, mixed gases are primarily used in welding and laser processing, such as welding shielding gases. Welding gases directly affect various gas shielded arc welding (GMA) processes, including welding performance (arc, spatter, penetration, smoke, etc.), speed, and efficiency. These effects are all due to the physical and chemical properties of the selected gases. During the production process, ultrapure gases are pre-filled into cylinders of varying sizes according to the type and ratio of gases used. After filling, the gas ratios are monitored using a gas analyzer to ensure accuracy. A gas analyzer is an instrument that uses gas sensors to detect gas types and concentrations. Sensors that detect gas composition and concentration using either physical or chemical methods are referred to as gas sensors.

[0003] In the prior art, there is a Chinese public patent with the patent number CN202122395427.4, which discloses a portable gas detector, which includes a detector body, a detection component and a shock-absorbing component; in this application, the detector body and the detection component cooperate with the shock-absorbing component to absorb shock and avoid damage to internal electrical components caused by touching the ground.

[0004] Although the above-mentioned cited documents can be used to detect ultra-pure gases in actual applications, they still have certain limitations when used for gas ratio detection in the ultra-pure gas production process. That is, the detection method in the document detects the gas in the cylinder after it is filled with gas, and the cylinder is always placed vertically. There is a problem of unstable connection between the gas inlet of the detector and the gas storage cylinder, which can easily cause gas leakage at the connection part, and the sealing performance is not high enough, and air can easily enter the interior, thereby affecting the detection effect. Therefore, an ultra-pure mixed gas ratio detection device is proposed to solve the above problem. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] Depend on Figure 1-4 Provided is an ultrapure mixed gas ratio detection device, comprising an ultrapure mixed gas ratio detection device body 1;

[0027] The side of the ultra-pure mixed gas ratio detection device body 1 is rectangular and is equipped with four horizontal shafts 2; the side ends of the four horizontal shafts 2 are commonly connected to a positioning plate 3, on which two cylinder push rods 5 are slidably provided, and the sides of the two cylinder push rods 5 are commonly installed with a mounting seat 6, and the side of the mounting seat 6 is connected to a cylinder limit assembly 7, and the cylinder limit assembly 7 is assembled with an ultra-pure mixed gas storage cylinder 8;

[0028] Two sets of guide rod cylinders 4 are installed on the side of the positioning plate 3. The output ends of the two sets of guide rod cylinders 4 pass through the positioning plate 3 and are connected to one end of the two cylinder push rods 5;

[0029] The cylinder limiting assembly 7 includes a positioning seat 71 provided on the side of the mounting seat 6. Two linear guide rails 72 are installed parallel to the side of the positioning seat 71. Two linear sliders 73 are slidably provided on the two linear guide rails 72. A sliding seat 74 is supported between the two adjacent linear sliders 73. Vertical plates 75 are vertically provided on the sides of the two sliding seats 74.

[0030] Clamping forks 76 are provided on opposite sides of the two vertical plates 75 .

[0031] In this embodiment, the mutual movement and coordination of multiple structures within the cylinder limiting assembly 7 are provided, so that the cylinder limiting assembly 7 can realize the clamping and limiting of the ultra-pure mixed gas storage cylinder 8; compared with the direct connection detection in the cited document, the gas ratio detection device of the present application is connected with the ultra-pure mixed gas storage cylinder 8 through the cylinder limiting assembly 7, so that when the ultra-pure mixed gas storage cylinder 8 is transporting gas, it can be ensured that the ultra-pure mixed gas storage cylinder 8 will not move during the detection process, thereby improving the stability and accuracy of gas detection and reducing the risk of gas leakage; and the linear push of the ultra-pure mixed gas storage cylinder 8 by the guide rod cylinder 4 makes the ultra-pure mixed gas storage cylinder 8 always docked with the gas inlet sealing nozzle 11, thereby further ensuring the airtightness between the ultra-pure mixed gas ratio detection equipment body 1 and the ultra-pure mixed gas storage cylinder 8, and reducing errors caused by poor connection.

[0032] Furthermore, by arranging two clamping forks 76 that are arranged to slide in opposite directions in the cylinder limit assembly 7, the cylinder limit assembly 7 can adapt to ultra-pure mixed gas storage cylinders 8 of various sizes, so that the ultra-pure mixed gas ratio detection equipment body 1 can process ultra-pure mixed gases of different volumes and detect them, further improving the versatility and flexibility of the ultra-pure mixed gas ratio detection equipment body 1. At the same time, the cylinder limit assembly 7 can adapt to ultra-pure mixed gas storage cylinders 8 of different sizes, and cooperate with the guide rod cylinder 4 to linearly push the ultra-pure mixed gas storage cylinder 8, so that the operator does not need to frequently replace the clamping structure or adjust the position of the ultra-pure mixed gas ratio detection equipment body 1, so that the ultra-pure mixed gas ratio detection equipment body 1 can quickly adapt to the use of different gas cylinders, improve overall operating efficiency, and reduce downtime.

[0033] Specifically, refer to Figure 2-4 The sides of the two clamping forks 76 are integrally provided with a semi-circular fork portion, and the two clamping forks 76 are both rubber products and are integrally formed.

[0034] In this embodiment, in actual use, the clamping fork 76 is made of one-piece molding, so that the clamping fork 76 can be pre-manufactured to adapt to ultra-pure mixed gas storage cylinders 8 of different sizes. In a preferred embodiment, when the size of the ultra-pure mixed gas storage cylinder 8 changes significantly and exceeds the clamping range of the current clamping fork 76, the user can replace the clamping fork 76 in advance and use another set of prefabricated clamping forks 76 to clamp the ultra-pure mixed gas storage cylinder 8 that exceeds the specification.

[0035] Furthermore, the surface of the clamping fork 76 has good friction, which can effectively enhance the grip of the ultra-pure mixed gas storage cylinder 8 and prevent the ultra-pure mixed gas storage cylinder 8 from sliding or falling during operation. The rubber material is relatively soft, which can effectively prevent the surface of the ultra-pure mixed gas storage cylinder 8 from being scratched or damaged during the clamping process, thereby maintaining the integrity and appearance of the ultra-pure mixed gas storage cylinder 8.

[0036] Specifically, refer to Figure 2-4 Two bearing seats 77 are also installed on the side of the positioning seat 71. A positive and negative screw rod 78 is rotatably provided between the two bearing seats 77. Two screw rod sliders 79 are engaged with the outside of the positive and negative screw rod 78. The two screw rod sliders 79 are respectively engaged with one of the threads of the positive and negative screw rod 78.

[0037] In this embodiment, when the forward and reverse screw rods 78 are rotating, they are limited by the sliding seat 74 and the linear slider 73, so that the two screw sliders 79 engaged on the outside of the forward and reverse screw rods 78 can drive the sliding seat 74 to move linearly along the forward and reverse spiral stroke of the forward and reverse screw rods 78, so that the two clamping forks 76 can perform opposite clamping movements or reverse separation movements within the stroke range of the forward and reverse screw rods 78.

[0038] Specifically, refer to Figure 3-4 , two screw sliders 79 are respectively connected to one of the sliding seats 74; a reciprocating motor 711 is also installed on the side of one of the bearing seats 77, and the output end of the reciprocating motor 711 passes through the bearing seat 77 and is connected to one end of the positive and negative screw rod 78.

[0039] In this embodiment, the reciprocating motor 711 is used to control the rotation of the forward and reverse screw rods 78. In a preferred embodiment, the reciprocating motor 711 is an existing device, and its power connection method is the existing technology. The control circuit can be realized through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0040] Specifically, refer to Figure 3-4 A bearing seat 710 is installed on the side of the positioning seat 71. The bearing seat 710 is located in the middle section of the positive and negative screw rod 78 and is arranged through it; a circular hole is opened on the side of the bearing seat 710 and can be used for the installation of the ultra-pure mixed gas storage cylinder 8.

[0041] In this embodiment, the supporting seat 710 can be used to cooperate with the circular hole opened at its end face for the installation of the ultra-pure mixed gas storage cylinder 8. The bottom end of the ultra-pure mixed gas storage cylinder 8 can be supported through the circular hole, thereby ensuring that the two clamping forks 76 can better clamp the ultra-pure mixed gas storage cylinder 8 and provide the ultra-pure mixed gas storage cylinder 8 with a more stable limit.

[0042] Specifically, refer to Figure 1-2 The side of the ultra-pure mixed gas ratio detection device body 1 is connected to a gas inlet sealing nozzle 11, and the gas inlet sealing nozzle 11 is arranged opposite to the gas outlet end of the ultra-pure mixed gas storage cylinder 8.

[0043] In this embodiment, in actual use, the ultra-pure mixed gas ratio detection device body 1 is equipped with an existing mature detection device, which can use a high-precision gas sensor to perform ratio detection on the ultra-pure mixed gas stored in the ultra-pure mixed gas storage cylinder 8. At the same time, the provided gas inlet sealing nozzle 11 can be connected to the ultra-pure mixed gas storage cylinder 8, thereby ensuring that the gas in the ultra-pure mixed gas storage cylinder 8 stably enters the ultra-pure mixed gas ratio detection device body 1.

[0044] Ultrapure mixed gas ratio detection device of this utility model:

[0045] The first step: in actual use, when the user needs to detect the ultra-pure mixed gas in the ultra-pure mixed gas storage cylinder 8, the ultra-pure mixed gas storage cylinder 8 is assembled on the cylinder limiting assembly 7, and then the cylinder limiting assembly 7 is used to clamp the ultra-pure mixed gas storage cylinder 8; at this time, the cylinder push rod 5 is driven by the output end of the guide rod cylinder 4, and the cylinder push rod 5 is connected and installed with the mounting seat 6, so that the mounting seat 6 can drive the cylinder limiting assembly 7 and the ultra-pure mixed gas storage cylinder 8 on the cylinder limiting assembly 7 to move linearly as a whole, so that the ultra-pure mixed gas storage cylinder 8 gradually moves and docks with the gas inlet sealing nozzle 11. At this time, the output of ultra-pure mixed gas by the ultra-pure mixed gas storage cylinder 8 is coordinated with the connection between the gas inlet sealing nozzle 11 and the ultra-pure mixed gas ratio detection device body 1, so that the ultra-pure mixed gas ratio detection device body 1 can detect the proportion of ultra-pure mixed gas. At the same time, the ultra-pure mixed gas storage cylinder 8 is limited by the cylinder limiting assembly 7 and the guide rod cylinder 4 pushes the ultra-pure mixed gas storage cylinder 8, so that the ultra-pure mixed gas storage cylinder 8 can always be docked with the gas inlet sealing nozzle 11, thereby ensuring air tightness. In addition, the set cylinder limiting assembly 7 can also adapt to ultra-pure mixed gas storage cylinders 8 of different sizes during use and clamp and install them.

[0046] Step 2: When the user adjusts the cylinder limit assembly 7, the user places the bottom end of the ultra-pure mixed gas storage cylinder 8 on the side of the support seat 710, and then connects the reciprocating motor 711 to a power source so that the reciprocating motor 711 can drive the forward and reverse screw rods 78 to rotate. When the forward and reverse screw rods 78 rotate, they are limited by the sliding seat 74 and the linear slider 73, so that the two screw sliders 79 engaged with the outside of the forward and reverse screw rods 78 can drive the sliding seat 74 to move linearly along the forward and reverse spiral stroke of the forward and reverse screw rods 78, so that the two clamping forks 76 can perform opposite clamping movements or reverse separation movements within the stroke range of the forward and reverse screw rods 78; the user can use the clamping forks 76 to complete the clamping and limiting of the ultra-pure mixed gas storage cylinder 8 by controlling the distance between the two clamping forks 76.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
