Description

Technical Field

[0001] The utility model relates to the technical field of CO2 online analysis equipment, in particular to a small CO2 online analyzer. Background Art

[0002] The carbon dioxide analyzer is an instrument for measuring the concentration of carbon dioxide. It mainly uses an optical interference gas analyzer, which consists of three parts: an optical system, a gas path system, and a circuit system.

[0003] Common carbon dioxide analyzers can be fixed indoors to monitor the indoor air environment. Since the principle of the analyzer is to let air enter the device and detect it through the internal optical part, this method requires air to enter passively;

[0004] Since the weight of carbon dioxide is greater than the weight of air (equal volume), carbon dioxide will generally accumulate at a lower position indoors. The analyzer that relies on passive air entry will cause different measurement results when placed at different heights. The analyzer is not easy to adjust the height after installation, which makes it impossible to detect and analyze carbon dioxide at different heights according to actual conditions. The scope of application is narrow. Therefore, a small CO2 online analyzer is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, the utility model provides a small CO2 online analyzer to solve the problem that the existing carbon dioxide analyzer can only detect and analyze carbon dioxide at a single location.

[0013] Furthermore, the threaded sleeve comprises a barrel, and a threaded hole and an extrusion hole are sequentially arranged inside the barrel from top to bottom, and the threaded hole is adapted to the external threaded barrel.

[0014] Furthermore, the extrusion hole is a truncated cone hole, the inner diameter of the top of the extrusion hole is larger than the inner diameter of the bottom thereof, and the extrusion hole is in contact with the outer surface of the clamping strip.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] See also Figure 1 and Figure 2 , a small CO2 online analyzer, characterized in that it includes:

[0033] Analyzer body 1.

[0034] The connection cover 2 includes a cover plate 21 , a top end of which is provided with a hollow threaded barrel 22 , and the hollow threaded barrel 22 is communicated with the analyzer body 1 .

[0035] Based on the above, the connection cover 2 is threadedly connected to the analyzer body 1 , and is connected to the connection member 3 by means of screws, so that the connection member 3 and the analyzer body 1 are connected to each other.

[0036] like Figure 1-Figure 3 As shown, the connecting member 3 includes a fan mounting block 31, and the fan mounting block 31 is connected to the connecting cover 2 by screws.

[0037] The fan mounting block 31 is provided with a mounting hole 32 inside. A vertical pipe 33 is provided at the bottom end of the fan mounting block 31, the vertical pipe 33 is communicated with the mounting hole 32, and a clamping strip 35 is provided at the bottom end of the vertical pipe 33. The clamping strips 35 are distributed in an annular shape and are equidistant. The side of the clamping strip 35 away from the center line of the vertical pipe 33 is an inclined surface. An external threaded barrel 34 is provided outside the vertical pipe 33.

[0038] Based on the above, the setting of the mounting hole 32 provides a working space for the fan block 4, so that the fan block 4 can drive the air to flow upward inside the mounting hole 32. The external threaded barrel 34 enables the threaded sleeve 5 to move vertically, thereby achieving the effect of squeezing the clamping strip 35. After squeezing, the clamping strip 35 undergoes elastic deformation and fits tightly against the outer wall of the air intake pipe 7, so that the position of the air intake pipe 7 can be fixed.

[0039] like Figure 1 and Figure 2 As shown, the fan block 4 includes a housing 41 , and the housing 41 is arranged inside the mounting hole 32 by screws. A cooling fan 42 is arranged inside the housing 41 .

[0040] Based on the above, the heat dissipation fan 42 plays a role in generating airflow, so that the air below the connecting member 3 can be sucked into it and flow into the interior of the analyzer body 1.

[0041] like Figure 2 , Figure 5-Figure 8 As shown, the air intake pipe 7 is arranged inside the connecting member 3 through a threaded sleeve 5 , and the air intake pipe 7 includes a first tube body 71 , a second tube body 72 , a third tube body 73 and a fourth tube body 74 .

[0042] The outer surfaces of the first tube body 71, the second tube body 72, the third tube body 73 and the fourth tube body 74 at both upper and lower ends are provided with annular grooves 76 and openings 77, and a sealing ring 6 is provided inside the annular groove 76. The outer surfaces of the first tube body 71 and the second tube body 72 are provided with side holes 75.

[0043] The sealing ring 6 is arranged outside the air intake pipe 7 and contacts the inner wall of the connecting member 3 .

[0044] Based on the above, the air intake pipe 7 cooperates with the cooling fan 42 so that the air outside the air intake pipe 7 can be sucked into it and flows along the direction of the air intake pipe 7. The setting with the side hole 75 plays the role of sucking air from spaces at different heights. The sucked air mixes with each other during the flow and enters the interior of the analyzer body 1. The air at this time can better represent the state of the air in the space. The air intake pipe 7 without the side hole 75 plays the role of fixed-point air suction, and passes the air into the interior of the analyzer body 1, achieving the effect of detecting and analyzing the air at a specific height. The setting of the sealing ring 6 makes the air intake pipe 7 and the vertical pipe 33 in a sealed state.

[0045] In actual use of this embodiment, the air intake pipe 7 can be removed and replaced by loosening the threaded sleeve 5. Different air intake pipes 7 can be replaced according to actual needs, and the length of the air intake pipe 7 can be adjusted to meet different needs.

[0046] After the air intake pipe 7 is installed and adjusted, the heat dissipation fan 42 is powered on to suck the air below the air intake pipe 7 into the analyzer body 1 for analysis.

[0047] The air intake pipe 7 is divided into two types, one with a side hole 75 and the other without a side hole 75. The air intake pipe 7 with a side hole can inhale air at different heights in the same space, and mix the air during the inhalation process, so that the air entering the analyzer body 1 is in the overall carbon dioxide state in the space.

[0048] The air intake tube without the side hole 75 can only inhale the air at a specific position, so that the analyzer body 1 can only detect and analyze the carbon dioxide state at the specific position;

[0049] Compared with the traditional analyzer, the analyzer is provided with the connecting piece 3, the fan block 4, the threaded sleeve 5 and the suction pipe 7 and other components. After the position of the analyzer is fixed, the carbon dioxide status at different heights in the space can be detected and analyzed, and different suction pipes 7 can be used to meet different environmental requirements, and the application range is wide.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
