Description

Technical Field

[0001] This utility model belongs to the field of dynamic dilution instrument technology, specifically a carbon dioxide split-type dynamic dilution instrument. Background Technology

[0002] The carbon dioxide split-type dynamic dilution apparatus is a modularly designed precision device that can dynamically dilute high-concentration carbon dioxide samples to the target concentration by precisely controlling the dilution ratio, meeting experimental or measurement needs. Its structure consists of a control unit, a dilution unit, and connecting pipelines. It achieves continuous dilution by dynamically adjusting the flow rate in real time, which is more efficient than static dilution, and the error can be controlled within 0.1%.

[0003] The split-type design offers advantages such as high flexibility, convenient maintenance, and wide adaptability, making it primarily used in environmental monitoring, chemical analysis, industrial manufacturing, biomedical research, and laboratory scientific research. A typical workflow includes the inflow of sample and diluent gases, precise mixing and dilution within the mixing chamber, and the output and detection of the diluted sample. Future development directions include high precision and low cost, intelligent and automated systems, green and low-energy design, and expanding applications in extreme environments. With its high efficiency, precision, and flexibility, the split-type dynamic dilution instrument holds significant value in scientific research and industrial production, and its application potential will continue to expand with technological advancements.

[0004] However, in practical use, some existing solutions suffer from non-split designs. The main drawbacks of non-split dynamic dilution systems are insufficient flexibility, complex maintenance, and poor adaptability. Due to fixed, integrated components, their modularity and scenario adaptability are low, limiting their application to different experimental needs. Equipment failure requires complete shutdown for repair, making maintenance and cleaning difficult and costly. Furthermore, non-split designs have weak upgrade capabilities, are difficult to expand functionality or customize, are inconvenient to transport and install, and are large and heavy, making them difficult to adapt to complex environments. Therefore, in contrast, split designs, with their modular flexibility, are more suitable for diverse needs and complex application scenarios.

[0005] Therefore, a carbon dioxide split-type dynamic dilution instrument is needed. Utility Model Content

[0006] In order to overcome the shortcomings of existing technologies and solve the problems of insufficient flexibility, complex maintenance and poor adaptability of non-split dynamic dilution instruments, this utility model proposes a split dynamic dilution instrument for carbon dioxide.

[0011] Furthermore, a first through hole is provided inside the rear side of the top end of the first connecting tube, and an insertion hole is provided on the rear right side of the top end of the first connecting tube.

[0012] Furthermore, a sealing sleeve is fixedly connected to the inner side of the top end of the second connecting pipe, a third sliding groove is provided at the bottom end of the sealing sleeve, a sealing plate is rotatably connected to the inner side of the sealing sleeve, and a transmission rod is fixedly connected to the rear side of the bottom end of the sealing plate, and the transmission rod is engaged with the insertion hole.

[0015] The advantages of this utility model's technical solution, which differs from existing technologies, are as follows:

[0016] 1. The present invention discloses a split-type dynamic dilution apparatus for carbon dioxide. By pressing the squeezing rod, the locking column is squeezed inward, thereby releasing the locking column from the second connecting tube.

The main unit 1, filter 11, and measuring device 12 are connected through the delivery pipe 13. The main unit 1 adopts a touch screen design, which is simple to operate and highly visual. Furthermore, all internal pipelines use inert materials, resulting in no loss of standard gas. The main unit 1 also has a temperature compensation function, which improves temperature adaptability. The device can be directly fixed and installed inside a cabinet.

[0039] The connecting assembly includes a first connecting pipe 2, a second connecting pipe 3 with the first connecting pipe 2 slidably connected to the inner side of the bottom end of the second connecting pipe 3, the first connecting pipe 2 being limited by the second connecting pipe 3, a second sliding groove 31 being provided at the bottom inner side of the second connecting pipe 3, a slider 29 being fixedly connected to the outer rear side of the first connecting pipe 2, the slider 29 being fixed by the first connecting pipe 2, the slider 29 being slidably connected to the second sliding groove 31, the slider 29 being limited by the second sliding groove 31.

[0040] A first groove 21 is provided on the inner side of the top end of the first connecting pipe 2. A first spring 22 is slidably connected to the inner side of the first groove 21. The first spring 22 is limited by the first groove 21. A left and right opposite locking post 23 is fixedly connected to the outer side of the first spring 22. The locking post 23 is pushed to both sides by the first spring 22 with the locking post 23 on both sides as stress points. The locking post 23 is slidably connected to the first groove 21. The locking post 23 is limited by the first groove 21.

[0041] A protective shell 27 is fixedly connected to the outside of the second connecting pipe 3, supporting and fixing the protective shell 27. A pressing rod 24 is slidably connected to the inside of the protective shell 27, limiting the pressing rod 24 so that it slides inside the protective shell 27. A retaining ring 25 is fixedly connected to the outside of the pressing rod 24, fixing the retaining ring 25. The retaining ring 25 is slidably connected to the inside of the protective shell 27, limiting its position. A second spring 26 is fixedly connected to one end of the inner side of the retaining ring 25, and one end of the inner side of the second spring 26 is fixedly connected to the second connecting pipe 3. The second spring 26 connects the second connecting pipe 3 and the retaining ring 25 simultaneously, and pushes the retaining ring 25 outward with the second connecting pipe 3 as the stress point.

[0042] A first through hole 28 is provided inside the rear side of the top end of the first connecting tube 2, and an insertion hole 210 is provided on the rear right side of the top end of the first connecting tube 2.

[0043] A sealing sleeve 32 is fixedly connected to the inner side of the top end of the second connecting pipe 3. The sealing sleeve 32 is supported and fixed by the second connecting pipe 3. A third sliding groove 37 is opened at the bottom end of the sealing sleeve 32. A sealing plate 34 is rotatably connected to the inner side of the sealing sleeve 32. The sealing plate 34 is limited by the sealing sleeve 32, so that the sealing plate 34 can rotate inside the sealing sleeve 32. A transmission rod 36 is fixedly connected to the rear side of the bottom end of the sealing plate 34. The transmission rod 36 is supported and fixed by the sealing plate 34. The transmission rod 36 is engaged with the insertion hole 210. The engagement of the insertion hole 210 and the transmission rod 36 forms an angle connection between the sealing plate 34 and the first connecting pipe 2, so that the sealing plate 34 and the first connecting pipe 2 can rotate simultaneously.

[0044] The sealing sleeve 32 has a second through hole 33 with the upper and lower sides facing each other on the rear side.

[0045] A third through hole 35 is provided on the rear side of the sealing plate 34. The third through hole 35 connects to the upper and lower opposite second through holes 33. When the sealing plate 34 rotates, the third through hole 35 rotates inside the sealing sleeve 32, thereby canceling the connection between the upper and lower opposite second through holes 33, thus sealing the top of the sealing sleeve 32.

[0046] Working principle: When the carbon dioxide split-type dynamic dilution instrument is disassembled, pressing the squeezing rods 24 on both sides simultaneously moves the squeezing rods 24 inward, driving the retaining ring 25 to move synchronously and compressing the second spring 26. Simultaneously, the squeezing rods 24 compress the locking column 23, causing it to move inward and releasing the engagement between the locking column 23 and the inner wall of the second connecting tube 3. This removes the angle restriction on the first connecting tube 2, allowing it to rotate. Then, rotating the first connecting tube 2 counterclockwise simultaneously drives the slider 29 to rotate synchronously within the second slide groove 31. After rotating the first connecting tube 2 counterclockwise by 90 degrees, the first connecting tube 2, along with the structure inside its top end, rotates simultaneously. During this process, the insertion hole 210 at the top of the first connecting tube 2 drives the transmission rod 36 to rotate, which in turn drives the sealing plate 34 and the third through hole. 35 rotates synchronously, thereby sealing the second through holes 33 on both sides through the sealing plate 34, canceling the connection between the upper and lower opposite second through holes 33, and sealing the top of the sealing sleeve 32. Then, the first connecting pipe 2 and the slider 29 can be pulled out from the second connecting pipe 3 and the second slide groove 31. During installation, the first connecting pipe 2 and the slider 29 are aligned with the second connecting pipe 3 and the second slide groove 31 respectively and inserted. Before insertion, the locking posts 23 on both sides are first pressed inward and moved to the inside of the first connecting pipe 2. The first connecting pipe 2 is inserted as a whole, and at the same time, the transmission rod 36 is also inserted into the insertion hole 210 to make the sealing plate 34 and the first connecting pipe 2 angularly connected. Then, the first connecting pipe 2 is rotated clockwise, which drives the sealing plate 34 and the third through hole 35 to rotate. After rotation, the locking posts 23 move outward and engage with the second connecting pipe 3, completing the fixation between the first connecting pipe 2 and the second connecting pipe 3.

[0047] The terms "front," "back," "left," "right," "top," and "bottom" all refer to the figures in the accompanying drawings. Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
