Description

A hydrogen purity detection and analysis device Technical Field

[0001] This utility model relates to the field of gas purity detection and analysis technology, and in particular to a hydrogen purity detection and analysis device. Background Technology

[0002] Hydrogen is a colorless gas with a density less than air (among all gases, hydrogen has the lowest density; under standard conditions, 1 liter of hydrogen weighs 0.0899 grams, much lighter than an equal volume of air). Because hydrogen is poorly soluble in water, it can be collected using the water displacement method. Hydrogen is widely used in educational, petroleum, chemical, metallurgical, power, coal mine, and water treatment environments, making the effective detection of hydrogen purity and the prevention of explosions particularly important.

[0003] Chinese Patent No. CN205384200U discloses a hydrogen purity detection and analysis device. The hydrogen collecting bottle is connected to an oxygen collecting bottle via a hose. The oxygen collecting bottle is connected to a vacuum pump via a hose. The filter cartridge is connected to a drying tower and the vacuum pump via a hose. The upper and lower parts of the measuring bottle are connected to a check valve and a primary leveling bottle, and a vibrator is installed at the bottom. The combustion bottle is connected to the check valve via a hose, and a platinum wire is installed inside the combustion bottle. A DC regulated power supply is electrically connected to the vibrator and the platinum wire via a wire. The secondary leveling bottle is connected to the outlet of the combustion bottle via a hose. This hydrogen purity detection and analysis device allows for adjustment of the oxygen feed rate. The filter cartridge and drying tower can respectively remove dust particles from the hydrogen-oxygen mixture and dry and remove carbon dioxide gas. The vibrator ensures uniform mixing of the gas mixture. The platinum wire and combustion bottle work together, and the measuring bottle measures the volume difference of the gas mixture before and after mixing, facilitating the analysis and calculation of hydrogen purity.

Two clamping components are threadedly connected to the outer periphery of the screw 403. Clamping component a includes a moving block 405, a clamping block 406, and an extension block 407. The moving block 405 has a through hole that is slidably connected to the outer periphery of the screw 403. Nuts 404 are connected to both sides of the moving block 405. The moving block 405 is connected to the clamping block 406. The two ends of the clamping block 406 are respectively connected to the extension block 407. The extension block 407 has a reserved mounting hole a. Clamping component a and clamping component b 408 have the same structure and are connected to the outer periphery of the gas supply interface 3. Connecting component 5 is connected inside the connecting box 101. Connecting component 5 includes an mounting component, a fixing component, and a connecting component. The mounting component is connected inside the connecting box 101 and connects the fixing component and the connecting component. The movable block 405 is connected to the screw 403 and fixed on both sides with nuts 404. Then, the clamping parts a and b 408 are aligned through the extended extension block 407 and installed with bolts, which facilitates installation on the gas inlet 3 and the outer surface of the gas pipe. This facilitates clamping and fixing of the connection node, avoids misalignment or unstable connection between the gas inlet 3 and the gas pipe, and improves the accuracy of hydrogen purity detection by the thermal conductivity hydrogen purity analyzer 2.

[0031] Further explanation: The support rod 401 is connected to the mounting plate a409, which has a pre-drilled mounting hole b. The mounting plate a409 is connected to the inner wall of the storage box 1 and is detachably connected. A flange screw is used to thread through the pre-drilled mounting hole b and the pre-drilled connection hole c on the inner wall of the storage box 1. This facilitates the connection between the mounting plate b409 and the storage box 1, and allows the auxiliary component 4 to be connected within the storage box 1. It also ensures the stability of the connection between the clamping parts a and b408 to the gas inlet 3 and the gas pipe, preventing gas leakage and improving the detection accuracy of the thermal conductivity hydrogen purity analyzer 2.

[0032] Example 2

[0033] As shown in Figures 3 and 4, the hydrogen purity detection and analysis device proposed in this utility model, based on the above embodiments, further details the specific components of the connecting component 5 and its cooperation method.

[0034] To further explain, the mounting components include a mounting cover 501, a base plate 502, and a fixing block 503; the mounting cover 501 is connected to mounting plate b at both ends, and mounting plate b and mounting plate a409 have the same structure; the mounting cover 501 is connected to the base plate 502, and the base plate 502 is connected to the fixing block 503 at both ends; the fixing block 503 is provided with a reserved mounting hole c, and the fixing block 503 is connected inside the connecting box 101. By providing pre-reserved connection holes b on the connecting box 101 for the corresponding fixing block 503 and mounting plate b, when the connecting assembly 5 is not in use, and the mounting cover 501 drives the base plate 502 to connect with the inside of the connecting box 101, the mounting plate b uses flange screws threaded through the pre-reserved mounting holes b and threaded to the corresponding pre-reserved connection holes, thus connecting the mounting cover 501 and the connecting box 101. At the same time, flange screws are threaded through the pre-reserved mounting holes c and threaded to the corresponding pre-reserved connection holes b, thus installing the fixing block 503 inside the connecting box 101, which facilitates a more stable connection between the connecting assembly 5 and the connecting box 101. When the base plate 502 drives the assembly to be removed from the connecting box 101 for use, the flange screws are operated to disassemble the fixing block 503 and the connecting box 101, and the connecting plate b and the connecting box 101. The operation is simple and convenient for clamping and positioning the removed thermal conductivity hydrogen purity analyzer 2.

[0035] Further explanation: The fixing components include a fixed clamping plate 504, a movable clamping plate 505, a rack 506, a gear 507, a rotating shaft 508, and a motor 509; the fixed clamping plate 504 and the movable clamping plate 505 are connected to the base plate 502, and one end of the movable clamping plate 505 is connected to the rack 506. The motor 509 is connected to the base plate 502, and the driving end of the motor 509 is connected to the rotating shaft 508. The rotating shaft 508 is connected to the gear 507, and the gear 507 drives the rack 506; the base plate 502 is provided with a moving groove, which is connected to a moving guide block, and the moving guide block is connected below the movable clamping plate 505; the movable clamping plate 505 and the fixed clamping plate 504 are connected to the thermal conductivity hydrogen purity analyzer 2. During the movement of the movable clamping plate 505, the movable guide block moves synchronously and along the movable groove, which helps to increase the movement stability of the movable clamping plate 505 and improve the fixed clamping of the movable clamping plate 505 and the fixed clamping plate 504 on the base plate 502, thereby improving the working effect of the thermal conductivity hydrogen purity analyzer 2.

[0036] Further explanation: The connector includes a fixed housing 510 and a connecting plate 511. The fixed housing 510 is connected to the base plate 502. The fixed housing 510 is hollow inside, with an opening at the top that connects to the connecting plate 511. The fixed housing 510 and the connecting plate 511 are connected on one side by tightening bolts. The connecting plate 511 is connected to the mounting plate a409 on one side and is detachably connected. The fixed housing 510 and the connecting plate 511 are telescopic structures. The fixed housing 510 and the connecting plate 511 are respectively provided with reserved threaded holes. The threads of the reserved threaded holes are engaged with the tightening bolts. The connecting plate 511 extends and retracts into the fixed housing 510 through the opening. The tightening bolts are threaded through the fixed housing 510 and the connecting plate 511 on one side for easy fixing of the connecting plate 511. The connecting plate 511 is also connected to the mounting plate a409 of the auxiliary component 4 for easy clamping and fixing of the removed gas transmission interface 3 connection node.

[0037] The working principle of this utility model is as follows: The gas is connected to the gas inlet 3 of the thermal conductivity hydrogen purity analyzer 2 and the gas pipe. Gas flows into the analyzer 2 for hydrogen concentration detection. During the connection process between the gas pipe and the inlet 3, clamping parts a and b 408 are connected to the outer surface of the inlet 3 and the gas pipe, securing the connection point and preventing gas leakage. This improves the accuracy of hydrogen purity detection and analysis by the thermal conductivity hydrogen purity analyzer 2. When the analyzer 2 needs to be removed from the storage box 1, firstly, the mounting plate b and the connecting box 101 are disassembled. The mounting plate b is connected to the mounting cover 501, allowing the cover 501 to be removed from the box 101. The cover 501 then moves the base plate 502, placing the analyzer 2 on the base plate 502 and connecting it to the fixing clamp 504. The motor 509 is then started, and the motor 509 drives the... Rotating the shaft 508 drives the gear 507, which in turn drives the rack 506. This causes the movable clamping plate 505 to move towards the thermal conductivity hydrogen purity analyzer 2, allowing the fixed clamping plate 504 to clamp the thermal conductivity hydrogen purity analyzer 2 onto the base plate 502. Adjusting and tightening the bolts allows the connecting plate 511 to be installed on the fixed housing 510. A pre-drilled connection hole a is provided on one side of the connecting plate 511. The pre-drilled mounting hole b on the mounting plate a aligns with the pre-drilled connection hole a. A screw is threaded through and connected to achieve the connection between the connecting plate 511 and the mounting plate a 409. This allows the auxiliary components 4, clamping parts a and b 408, to be disassembled from the inside of the storage box 1 and connected to the connecting plate 511 for use with the base plate 502. This facilitates the clamping of the gas inlet 3 of the thermal conductivity hydrogen purity analyzer 2, improving its usability and enhancing its performance in hydrogen purity detection and analysis.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
