Description

Technical Field

[0001] The present application relates to the technical field of gas processing, and more specifically, to a pre-processing device of a magnetic oxygen analyzer with a booster pump. Background Art

[0002] At present, in chemical production equipment, we often encounter sample systems that need to analyze micro-pressure, normal pressure or even negative pressure. In this case, the analyzer pretreatment system needs to be equipped with a booster pump; some are equipped at the front end of the instrument to boost the sample before entering the instrument for analysis; some are equipped at the back end of the instrument to suck the sample over. However, since the output pressure of the booster pump is difficult to stabilize, most of them are similar to pulse output, which will cause the flow and pressure entering the instrument to fluctuate, thereby causing unstable measurement values; especially the dumbbell ball magnetic oxygen analyzer, which is more sensitive to flow changes. In severe cases, it will cause the measurement value to fluctuate by 3%, especially some interlocking instruments, which require the instrument measurement value fluctuation range to be within 0.2%, so it is difficult to meet the process production requirements.

[0030] Example:

[0031] The present application embodiment discloses a magnetic oxygen analyzer pretreatment device with a booster pump, please refer to Figure 1 and Figure 2 , comprising a device body 1, a base 2 is provided at the bottom of the device body 1, a groove 3 is provided inside the device body 1, connecting grooves 4 are provided on both sides of the inside of the groove 3, an activated carbon filter plate 5 is connected inside the groove 3, connecting plates 6 are installed on both sides of the outside of the activated carbon filter plate 5, a handle 7 is installed on the front side of the activated carbon filter plate 5, a sealing gasket 8 of the same shape is provided at one end of the activated carbon filter plate 5, and two symmetrical limit components 9 are provided between the activated carbon filter plate 5 and the device body 1;

[0032] When the activated carbon filter plate 5 is located inside the groove 3, the connecting plate 6 is located inside the connecting groove 4 and slides. The setting of the sealing gasket 8 increases the tightness of the connection between the activated carbon filter plate 5 and the device body 1 to prevent the gas in the device body 1 from flowing out. The setting of the handle 7 facilitates pulling the activated carbon filter plate 5.

[0033] See also Figure 3 , Figure 4 and Figure 5 The limiting assembly 9 includes a rotating shaft 91 rotatably connected to the inside of the device body 1, a mounting frame 92 is installed at one end of the rotating shaft 91, a through slot 93 is provided inside the mounting frame 92, a rotating plate 94 is installed on the outer side of the mounting frame 92, a fixing frame 95 is installed on the outer side of the activated carbon filter plate 5, a notch 96 and a rotating slot 97 are respectively provided inside the fixing frame 95, a connecting rod 98 is connected inside the fixing frame 95 and located at the position of the notch 96, a card plate 99 is installed at one end of the connecting rod 98, a pull plate 910 is installed at the other end of the connecting rod 98, a spring 911 is installed on the outer side of the fixing frame 95 and located outside the connecting rod 98, the spring 911 is connected to the pull plate 910, and a plurality of groups of rubber pads 912 with equal distances are arranged on the outside of the pull plate 910;

[0034] The rotating shaft 91 is rotatably connected to the inside of the device body 1, and the mounting frame 92 is located inside the rotating groove 97 for rotation. When the clamping plate 99 is located inside the through groove 93, the mounting frame 92 can be fixed inside the rotating groove 97. The rubber pad 912 protects the user's hands and facilitates the user to pull the pull plate 910. The size of the clamping plate 99 is the same as the size of the slot 96.

[0035] The implementation principle of this embodiment is as follows: the device body 1 is the existing structure in the publication number CN218995239U, which includes: a frame, an air inlet pipe, an exhaust pipe, a mounting shaft, a stirring blade, a first inclined plate, a second inclined plate, a plate body, a support rod, a hemispherical member, a water outlet pipe, a one-way valve, a support plate, a motor, a gas flow channel, a through hole, a mounting rod, a fan blade, and a hollow protective plate;

[0036] An activated carbon filter plate 5 is arranged in the device body 1, which can filter a small amount of impurities contained in the gas. The activated carbon filter plate 5 is fixed inside the groove 3 by the setting of the limit assembly 9. The activated carbon filter plate 5 increases the tightness of the connection with the device body 1 through the set sealing gasket 8 to avoid airflow leakage; after long-term use, the activated carbon filter plate 5 is subsequently pulled out from the inside of the groove 3 by the limit assembly 9, which is convenient for the staff to replace or clean;

[0037] When the activated carbon filter plate 5 needs to be taken out from the groove 3, the user first holds the pull plate 910 and pulls it outwards. The pull plate 910 drives the clamping plate 99 to move through the connecting rod 98. At this time, the spring 911 is in an elongated state. When the clamping plate 99 is located inside the notch 96, the clamping plate 99 is separated from the inside of the through groove 93. At this time, the user holds the position of the rotating plate 94 and rotates the mounting frame 92 through the rotating shaft 91, so that the mounting frame 92 is located at the position of the rotating groove 97 and rotates and separates from the inside of the rotating groove 97. Both the two limiting components 9 perform this operation. Then, the user holds the handle 7 and pulls the activated carbon filter plate 5 out of the groove 3, so that the activated carbon filter plate 5 can be replaced or cleaned.

[0038] When the activated carbon filter plate 5 is subsequently connected to the groove 3, the rotating shaft 91 is first rotated to prevent the rotating shaft 91 from being blocked in the position of the groove 3, and then the connecting plates 6 installed on both sides of the activated carbon filter plate 5 are located inside the connecting groove 4. When the activated carbon filter plate 5 is located inside the groove 3, the user holds the pull plate 910 and pulls it outward. At this time, the spring 911 is in an elongated state. When the card plate 99 is located inside the notch 96, the user holds the rotating plate 94 and rotates the mounting frame 92 through the rotating shaft 91 to locate the mounting frame 92 inside the rotating groove 97. When the position of the card plate 99 corresponds to the position of the through groove 93, the user releases the pull plate 910. The spring 911 is set to enable the pull plate 910 to drive the connecting rod 98 and the card plate 99 installed at one end to reset. At this time, the card plate 99 is located inside the through groove 93, and the mounting frame 92 is fixed to the inside of the rotating groove 97. At this time, the activated carbon filter plate 5 can be fixed inside the groove 3. The activated carbon filter plate 5 is connected to the device body 1 tightly by the setting of the sealing gasket 8.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
