Technical Field

[0001] This utility model relates to the field of dust concentration measurement technology, and in particular to a flue gas pipeline system for a dust concentration measurement device. Background Technology

[0002] Accurate measurement of dust concentration is crucial in various fields, including industrial production, environmental monitoring, and occupational health. Excessive dust concentration can not only cause safety accidents and threaten worker health, but also damage production equipment and affect the stability of the production process. Therefore, dust concentration measuring devices play a key role in these fields.

[0003] Currently, existing dust concentration measuring devices have certain limitations in terms of piping systems, especially in multi-condition applications. Existing dust concentration measuring devices often use standardized piping systems, which can only meet general measurement needs. In practical applications, due to the diversity and complexity of operating conditions, standardized piping systems are often difficult to adapt to various specific scenarios. One significant problem is the insufficient length of the measuring tube. In some operating conditions, due to the long distance between measurement points, the existing measuring tube length may not meet the actual needs, easily leading to inaccurate measurements or even the inability to perform effective measurements. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a flue gas pipeline system for a dust concentration measuring device, which solves the problem that the standardized pipeline system of the existing dust concentration measuring device cannot be adapted to multiple working conditions.

[0005] To achieve the above and other related objectives, this utility model provides a flue gas pipeline system for a dust concentration measuring device, including a measuring chamber and an optical path measuring module.

[0026] Before describing the embodiments of this utility model in detail, the application environment of this utility model will be described first. The technology of this utility model is mainly applied to the field of dust concentration measurement technology. This utility model is used to solve the problem that the standardized pipeline system of existing dust concentration measurement devices cannot be adapted to multi-condition applications.

[0027] Please combine Figures 1 to 4 As shown, this utility model provides a flue gas pipeline system for a dust concentration measuring device.

[0028] In an exemplary embodiment of this application, the flue gas duct system of the dust concentration measuring device includes a measuring chamber 1 and an optical path measuring module 2. The optical path measuring module 2 is used to measure the dust concentration in the flue gas within the measuring chamber 1. The flue gas duct system includes:

[0029] The intake pipe 3 includes a guide section 301, a detachable section 302, and a fixed section 303. The detachable section 302 is detachably connected between the guide section 301 and the fixed section 303. The fixed section 303 is fixedly connected to the device. The guide section 301 is used to guide the flue gas in the flue into the intake pipe 3. The fixed section 303 is connected to the measuring chamber 1 through the intake branch pipe 304. The exhaust pipe 4 is used to discharge the flue gas in the measuring chamber 1 out of the device.

[0030] In this embodiment, a detachable section 302 is provided between the guide section 301 of the air inlet pipe 3 and the fixed section 303 fixedly installed on the device. When dealing with working conditions where the distance between measurement points is far, the length of the air inlet pipe 3 can be extended by replacing the detachable section 302. The flue gas pipeline system of the dust concentration measuring device proposed in this application has higher flexibility and scalability, can meet the needs of multiple working conditions, and effectively improves the compatibility of the device; it also has the advantages of low replacement cost and convenience.

[0031] It is worth noting that the air inlet of the guide section 301 is oriented opposite to the flow direction of the fluid in the flue, which can more effectively guide the fluid into the guide section 301; the air inlet pipe 3 also includes an air inlet branch pipe 304, and the fixed section 303 is connected to the measuring chamber 1 through the air inlet branch pipe 304; the exhaust pipe 4 includes an exhaust branch pipe 401 and an exhaust bend pipe 402. The exhaust branch pipe 401 is located inside the device, and the exhaust bend pipe 402 is located outside the device. The exhaust bend pipe 402 is an "L" shaped bend pipe. The exhaust bend pipe 402 is connected to the measuring chamber 1 through the exhaust branch pipe 401, and the flue gas is discharged from the device through the "L" shaped exhaust bend pipe 402 to avoid the flue gas flow direction of the exhaust device being perpendicular to the flue gas flow direction in the flue, thereby avoiding the flue gas turbulence phenomenon in the flue.

[0032] In an exemplary embodiment of this application, the guide section 301 is a gooseneck tube.

[0033] In this embodiment, the gooseneck tube design uses a smoothly transitioned curved section, avoiding the increase in fluid resistance caused by right-angle turns. This helps the flue gas flow more smoothly in the guide section 301, reducing energy loss. Due to the reduced fluid resistance, the gooseneck tube can significantly improve the transmission efficiency of the flue gas, and more flue gas can be effectively guided into the dust measuring device, thereby improving the accuracy and reliability of the measurement.

[0034] In an exemplary embodiment of this application, a first connector 5 is provided on the guide section 301, and a mounting groove 302a is provided on the detachable section 302 for installing the first connector 5.

[0035] In this embodiment, the first connector 5 is welded and fixed to the guide section 301. The first connector 5 is coaxially provided with a first through hole 503 on the guide section 301, so that the flue gas can enter the detachable section 302 through the first connector 5.

[0036] In an exemplary embodiment of this application, the first connector 5 is provided with an annular groove 501 and a pressing part 502. A first sealing groove 6 is formed between the pressing part 502, the end face of the mounting groove 302a, and the bottom of the annular groove 501. The first sealing groove 6 is used to install a first sealing component 7. The first sealing component 7 is used to seal the connection end between the first connector 5 and the detachable section 302.

[0037] In this embodiment, the annular groove 501 is used for quick positioning of the installation of the first sealing component 7, which is a sealing ring, and the outer diameter of the extrusion part 502 is the same as the outer diameter of the mounting groove 302a.

[0038] In an exemplary embodiment of this application, a locking connector 8 is further included. The locking connector 8 is threadedly connected to the detachable section 302 and abuts against the extrusion part 502. The locking connector 8 is used to apply a pre-tightening force to the extrusion part 502 to extrude the first sealing member 7.

[0039] In this embodiment, the locking connector 8 is provided with a second through hole 801, and the locking connector 8 passes through the second through hole 801 onto the guide section 301; the outer wall surface of the mounting groove 302a is machined with external threads, the locking connector 8 is sleeved on the outer wall surface of the mounting groove 302a and threadedly connected to the outer wall surface of the mounting groove 302a, and the inner bottom surface of the locking connector 8 abuts against the extrusion part 502. Through the threaded engagement between the locking connector 8 and the mounting groove 302a, the extrusion part 502 is extruded, causing the extrusion part 502 to extrude the first sealing component 7, thereby providing a sealing pre-tightening force for the first sealing component 7.

[0040] In an exemplary embodiment of this application, a second connector 9 is provided on the detachable section 302, and the detachable section 302 is threadedly connected to the second connector 9.

[0041] In this embodiment, the second connector 9 is threadedly connected to the fixed section 303. The second connector 9 is coaxially provided with a third through hole 903 on the detachable section 302, so that the flue gas can enter the fixed section 303 from the detachable section 302 through the third through hole 903.

[0042] In an exemplary embodiment of this application, a second sealing member 10 is provided between the detachable segment 302 and the second connector 9. The second sealing member 10 is used to seal the connection end between the detachable segment 302 and the second connector 9.

[0043] In this embodiment, the second sealing component 10 includes, but is not limited to, the use of an O-ring. The second sealing component 10 is used to seal the connection end between the detachable section 302 and the second connector 9 to prevent flue gas from leaking from the connection end between the detachable section 302 and the second connector 9.

[0044] In an exemplary embodiment of this application, the second connector 9 is provided with a limiting part 901, which abuts against and limits the end face of the fixed section 303.

[0045] In this embodiment, the outer diameter of the limiting part 901 is larger than the outer diameter of the fixed section 303. By designing the limiting part 901, the operator can easily perceive that the second connecting piece 9 and the fixed section 303 are installed in place.

[0046] In an exemplary embodiment of this application, the second connector 9 is provided with a second sealing groove 902, which is used to install a third sealing component 11, and the third sealing component 11 is pressed into the inner wall of the fixed section 303.

[0047] In this embodiment, the third sealing component 11 includes, but is not limited to, the use of an O-ring. The third sealing component 11 is deformed by the inner wall of the fixed section 303 and a compressive force is applied radially inward along the fixed section 303.

[0048] In an exemplary embodiment of this application, a third sealing groove 303a is provided on the fixed section 303. The third sealing groove 303a is used to install the fourth sealing component 12. The fourth sealing component 12 is pressed into the outer wall of the second connector 9.

[0049] In this embodiment, the fourth sealing component 12 includes, but is not limited to, the use of an O-ring. The fourth sealing component 12 is deformed by the outer wall of the second connector 9 and applies a compressive force outward along the radial direction of the fixed section 303. The fourth sealing component 12, together with the third sealing component 11, forms a double seal at the connection end between the second connector 9 and the fixed section 303, effectively ensuring the sealing effect.

[0050] In terms of working principle, this application provides a detachable section 302 between the guide section 301 of the air inlet pipe 3 and the fixed section 303 fixedly installed on the device. When dealing with situations where the measurement points are far apart, the length of the air inlet pipe 3 can be extended by replacing the detachable section 302.
