Description

Technical Field

[0001] The present invention belongs to the technical field of silica analyzers, and particularly relates to a leak-proof device for a silica analyzer. Background Art

[0002] The silica analyzer uses a specially designed light source with patented technology, pre-programs curves in accordance with international standard water quality detection methods and relevant standards, and is strictly calibrated and verified at the factory in an international standard laboratory. The microcomputer ion measuring instrument can measure one or more ions. When the supporting reagent is added, the sample will undergo a color reaction, and the change of the color reaction is proportional to the ion concentration of the sample to be measured. The microcomputer ion measuring instrument measures the color change; When in use, the silica analyzer will use a corresponding leak-proof device. The traditional leak-proof device includes structures such as an instrument air source, a pressure regulator, a solenoid valve, and a microswitch. The advantage of this leak-proof device is that it can limit the working pressure of the instrument air source; However, due to the relatively simple structure of the traditional leak-proof device, there is still a risk of reagent leakage in the silica analyzer. When the user opens the sealed door of the instrument, the leaked reagent inside the instrument will float into the air and pollute the environment, which urgently needs to be improved.

[0021] The working principle and usage process of the present invention: During use, structures such as cuvettes and reaction cells are installed inside the leak-proof hollow storage tube 20, and the partition lifting plate 355 provides support for the above-installed structures. In the initial state, the movable adjusting plate 32 is located on the top of the gas storage metal box 31. At this time, the rotatable lifting disc 352 cooperates with the metal locking plate 36 to provide support for the movable adjusting plate 32. During the detection process, the cuvette and the reaction cell are inside the closed leak-proof hollow storage tube 20, thus avoiding reagent leakage during the detection process. After the detection is completed, when the sealing door on the instrument is opened, the adjustable-speed power driving member 356 drives the rotatable lifting disc 352 to rotate a target angle so that the unlocking hole 351 rotates to a position corresponding to the metal locking plate 36 (this angle can be preset, such as 15°, 20°, 30°, etc., as long as it is reasonable). At this time, the second deformable position-changing member 345 in the stretched state drives the movable adjusting plate 32 to move downward instantaneously. After the movable adjusting plate 32 moves downward, the rotatable lifting disc 352 resets. When the movable adjusting plate 32 moves downward, a negative pressure is formed at the bottom of the leak-proof hollow storage tube 20. At this time, the air above the partition lifting plate 355 in the leak-proof hollow storage tube 20 is transported to the lower part of the partition lifting plate 355 through the fourth single-pass gas transmission protection pipe 354, and the air outside the leak-proof hollow storage tube 20 enters the top of the leak-proof hollow storage tube 20 through the first single-pass gas transmission protection pipe 21, thereby realizing an instantaneous replacement of the air above the partition lifting plate 355 in the leak-proof hollow storage tube 20. At this time, the user can operate the instrument with confidence without worrying about reagent leakage problems. Secondly, when the movable pressure regulating plate 32 moves downward, the air at the bottom of the air storage metal box 31 is discharged through the second one-way air transmission protection pipe 30. At this time, the second one-way air transmission protection pipe 30 is connected to a special air purifier through a pipeline to purify the discharged gas. After the movable pressure regulating plate 32 moves downward to replace the air at the top of the leak-proof hollow storage pipe 20, the first deformable position changing member 344 is controlled to extend so that the third limit metal lifting plate 343 lifts. When the movable pressure regulating plate 32 moves upward, the mutual cooperation of the rotatable lifting disc 352 and the metal locking plate 36 is used to provide locking support for the movable pressure regulating plate 32. After the movable pressure regulating plate 32 is locked, the first deformable position changing member 344 contracts to lower the third limit metal lifting plate 343 to its original position, so as to provide space for the subsequent instantaneous downward movement of the movable pressure regulating plate 32. Moreover, during the upward movement of the movable pressure regulating plate 32, the air between the movable pressure regulating plate 32 and the partition lifting plate 355 passes through the third one-way air transmission protection pipe 37 and enters the lower part of the movable pressure regulating plate 32, and can be discharged when the movable pressure regulating plate 32 moves downward next time; Thus, through the mutual cooperation of multiple structures, a closed detection environment is built. And when the user opens the sealed door of the instrument, the air in the detection environment can be instantaneously extracted and replaced, thus avoiding the situation of reagent leakage and preventing the leaked reagent from floating into the air and polluting the environment. Secondly, the present invention can be applied to different models of silica analyzers, making the applicable range of the leak-proof device wider. In addition, the structure of the present invention is simple and easy to use, and is worthy of popularization and use.
