Description

Technical Field

[0001] This invention relates to the field of flue gas sampling technology, and in particular to a composite flue gas sampling device and sampling method. Background Technology

[0002] In the process of flue gas sampling, foaming agents are usually used to seal the sampling device and the sampling port. However, this sealing method makes the disassembly of the sampling device extremely cumbersome. Therefore, in order to facilitate the installation and disassembly of the sampling device and the flue sampling port, a composite flue gas sampling device is needed.

[0003] In existing technologies, most flue gas sampling devices are disassembled by manually breaking up the solidified foaming agent to separate the sampling device from the sampling port of the flue. This operation increases the labor intensity of sampling personnel and reduces the overall efficiency of sampling work. Summary of the Invention

[0004] The purpose of this invention is to provide a composite flue gas sampling device and sampling method to solve the technical problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A composite flue gas sampling device, comprising: The sampling tube has a sealing seat fixedly fitted on its outer side wall; Multiple transmission rods, each of which rotatably penetrates the outer wall of the sealing seat, and each transmission rod has multiple equally spaced blades fixed to its outer wall; An annular plate, wherein the annular plate and each transmission rod are rotatably connected, and a transmission assembly is provided on the side wall of the annular plate, the transmission assembly being used to drive the transmission rod to rotate; A telescopic assembly is disposed on the outer wall of the annular plate and is connected to a sealing seat. The telescopic assembly is used to drive the blade to move. A power assembly is disposed on the outer wall of the sampling tube and is used to drive the transmission assembly.

[0006] A further improvement of the present invention is that the transmission assembly includes: The first gear is rotatably mounted on the side wall of the annular plate, and the first gear and the transmission rod are fixed. A connecting ring, which is fixed to the inner wall of the annular plate; A first gear ring and a second gear ring are rotatably mounted on the outer wall of the connecting ring. The first gear ring and the second gear ring are fixed, and the first gear and the second gear ring mesh with each other.

[0007] A further improvement of the present invention is that the telescopic component includes: The second gear is rotatably mounted on the outer wall of the annular plate, and the second gear and the second gear ring mesh with each other; A lead screw is rotatably mounted on the outer wall of the sealing seat. The outer wall of the annular plate has a threaded hole that is compatible with the lead screw. The lead screw and the second gear are fixed.

[0008] A further improvement of the present invention is that the power assembly includes: A motor is mounted on the outer wall of the sampling tube. A rotating shaft is mounted on the output shaft of a motor, and a polygonal groove is provided at the end of the rotating shaft; A prism, which is slidably inserted into a polygonal slot.

[0009] A further improvement of the present invention is that it further includes: A connecting plate is disposed on the inner side wall of the connecting ring, and a third gear is rotatably disposed on the side wall of the connecting plate, and the third gear is fixed to the prism.

[0010] A further improvement of this invention is that the motor is a servo motor.

[0011] A further improvement of the present invention is that an input pipe is provided through the outer wall of the sealing seat.

[0012] A further improvement of the present invention is that the input pipe is used to inject foaming agent into the sealing seat.

[0013] A further improvement of the present invention is that the plurality of transmission rods are evenly distributed circumferentially.

[0014] A composite flue gas sampling method, the method being based on the aforementioned composite flue gas sampling device, comprising: Place the sealing seat at the sampling port of the flue, inject foaming agent into the sealing seat, and after the foaming agent solidifies, it can be used in conjunction with the sealing seat to seal the sampling tube and the sampling port for sampling. After the sampling work is completed, turn on the power component switch. During the operation of the power component, the telescopic component is driven to rotate. During the rotation of the transmission component, the transmission rod is driven to rotate, which in turn causes the blade on the transmission rod to rotate and cut off the solidified foaming agent. During the rotation of the telescopic assembly, the threaded holes on the annular plate enable the annular plate to move, which in turn causes the transmission rod and the blade to move. The rotating blade then crushes the foaming agent between the sealing seat and the sampling port, thereby enabling the disassembly of the sampling device.

[0015] Compared with the prior art, the present invention has at least the following beneficial technical effects: This invention provides a composite flue gas sampling device and method. After sampling, the invention incorporates a unique dismantling mechanism. A power component drives a transmission component, which in turn rotates a transmission rod, causing the blade to rotate and cut off the solidified foaming agent. Simultaneously, a telescopic component rotates in conjunction with threaded holes on an annular plate, enabling the annular plate to move, which in turn moves the transmission rod and the blade. This combination of rotation and movement allows for comprehensive and multi-angle crushing of the foaming agent between the sealing seat and the sampling port, greatly simplifying the dismantling process and improving efficiency. By using the rotation and movement of the blade, this invention crushes the foaming agent in a gentler and more precise manner, reducing the risk of damage to the sampling device and sampling port, extending the equipment's lifespan, and reducing maintenance and replacement costs due to equipment damage.

[0016] The entire device of this invention consists of a sampling tube, a sealing seat, a transmission rod, a blade, an annular plate, a telescopic assembly, and a power assembly. The components are rationally arranged, tightly connected, and have a compact structure. The operation process of this invention is relatively simple. For sealing, only the foaming agent needs to be injected and allowed to solidify; for disassembly, simply turn on the power assembly switch. The power assembly then drives the transmission and telescopic assemblies sequentially, achieving the crushing of the foaming agent and the disassembly of the device. Operators do not require complex operating skills or extensive professional training, reducing operational difficulty and manpower requirements, and improving work efficiency. Due to the sealing method of the sealing seat and foaming agent working together, as well as the unique disassembly mechanism, this composite flue gas sampling device is adaptable to different types and specifications of flue gas sampling ports.

[0017] Furthermore, the present invention drives the lead screw to rotate during the rotation of the second gear, which, in conjunction with the threaded hole on the annular plate, enables the annular plate to move, thereby causing the transmission rod and the blade to move. Through the rotating blade, the foaming agent between the sealing seat and the sampling port is crushed, thereby enabling the rapid disassembly of the device. Attached Figure Description

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] Example 1 like Figures 1 to 3 As shown, an embodiment of the present invention provides a composite flue gas sampling device, comprising: Sampling tube 1, with a sealing seat 2 fixedly sleeved on the outer wall of sampling tube 1; Multiple transmission rods 12, each of which rotates through the outer wall of the sealing seat 2, and each transmission rod 12 has multiple equally spaced blades 13 fixed to its outer wall. An annular plate 3 and each transmission rod 12 are rotatably connected. A transmission assembly is provided on the side wall of the annular plate 3, which is used to drive the transmission rod 12 to rotate. The telescopic assembly is disposed on the outer wall of the annular plate 3 and is connected to the sealing seat 2. The telescopic assembly is used to drive the blade 13 to move. The power assembly is located on the outer wall of the sampling tube 1 and is used to drive the transmission assembly.

The first toothed ring 7 and the second toothed ring 8 are fixed, and the first gear 9 and the second toothed ring 8 mesh with each other.

[0032] Furthermore, the telescopic component includes: The second gear 10 is rotatably mounted on the outer wall of the annular plate 3, and the second gear 10 and the second gear ring 8 mesh with each other; The lead screw 11 is rotatably mounted on the outer wall of the sealing seat 2. The outer wall of the annular plate 3 has a threaded hole that is compatible with the lead screw 11. The lead screw 11 and the second gear 10 are fixed.

[0033] Furthermore, the powertrain components include: Motor 4 is mounted on the outer wall of sampling tube 1; motor 4 is a servo motor. Rotary shaft 5 is mounted on the output shaft of motor 4, and a polygonal groove is provided at the end of the rotating shaft 5. Prism 6 is slidably inserted into the polygonal slot.

[0034] Furthermore, it also includes: A connecting plate 15 is disposed on the inner side wall of the connecting ring 14. A third gear 16 is rotatably disposed on the side wall of the connecting plate 15, and the third gear 16 is fixed to the prism 6.

[0035] Furthermore, an inlet pipe 17 is provided through the outer wall of the sealing seat 2.

[0036] Example 2 like Figures 1 to 3 As shown, this embodiment of the invention provides a composite flue gas sampling method, including: Place the sealing seat 2 at the sampling port of the flue, inject foaming agent into the sealing seat 2, and after the foaming agent solidifies, it can be used in conjunction with the sealing seat 2 to seal the sampling tube 1 and the sampling port for sampling. After the sampling work is completed, turn on the power component switch. During the operation of the power component, the telescopic component is driven to rotate. During the rotation of the transmission assembly, the transmission rod 12 is driven to rotate, which in turn causes the blade 13 on the transmission rod 12 to rotate and cut off the solidified foaming agent. During the rotation of the telescopic assembly, the annular plate 3 moves in conjunction with the threaded hole on the annular plate 3, thereby causing the transmission rod 12 and the blade 13 to move. The rotating blade 13 causes the foaming agent between the sealing seat 2 and the sampling port to be crushed, thereby enabling the dismantling of the sampling device.

[0037] The specific working method is as follows: When in use, place the sealing seat 2 at the sampling port of the flue, inject foaming agent into the sealing seat 2 through the input pipe 17, and after the foaming agent solidifies, it can work with the sealing seat 2 to seal the sampling tube 1 and the sampling port, and then the sampling work can be carried out. After the sampling work is completed, the switch of motor 4 is turned on. During the operation of motor 4, the rotating shaft 5 and prism 6 are driven to rotate, which in turn drives the third gear 16 to rotate. During the rotation of the third gear 16, the first gear ring 7 and the second gear ring 8 are driven to rotate, which in turn causes the first gear 9 and the second gear 10 to rotate. During the rotation of the first gear 9, the transmission rod 12 is driven to rotate, which in turn causes the blade 13 on the transmission rod 12 to rotate and cut off the solidified foaming agent. During the rotation of the second gear 10, the lead screw 11 is driven to rotate, which, in conjunction with the threaded hole on the annular plate 3, enables the annular plate 3 to move, thereby causing the transmission rod 12 and the blade 13 to move. Through the rotating blade 13, the foaming agent between the sealing seat 2 and the sampling port is crushed, thereby enabling the rapid disassembly of the sampling device.

[0038] This invention achieves a seal between the sampling tube and the sampling port by fixing a sealing seat to the outer wall of the sampling tube and injecting a foaming agent into the sealing seat through an input pipe. After solidification, the foaming agent has excellent flowability and expansion properties, automatically filling irregular gaps between the sampling port and the sealing seat to form a tight and fitting sealing layer. This adaptive sealing method eliminates the need for precise matching of the sampling port size and shape, greatly improving the reliability and stability of the seal, effectively preventing flue gas leakage during sampling, and ensuring the accuracy and authenticity of the sampling data. After solidification, the foaming agent possesses a certain strength and durability, maintaining a good sealing state for a considerable period and is not easily affected by external environmental factors.

[0039] This invention uses an electric motor as a power source, achieving precise power transmission and conversion through transmission components such as a rotating shaft, prism, and gear set. The motor drives the rotating shaft and prism to rotate, which in turn drives the third gear to rotate. The third gear then drives the first and second gear rings to rotate, causing the first and second gears to rotate synchronously. This multi-stage gear transmission design allows for adjustment of the transmission ratio according to actual needs, achieving precise control over the rotational speed of the transmission rod and the moving speed of the annular plate, improving the flexibility and efficiency of the dismantling operation. The first gear drives the transmission rod to rotate, causing the blades on the transmission rod to rotate, initially removing the solidified foaming agent; simultaneously, the second gear drives the lead screw to rotate, cooperating with the threaded holes on the annular plate to move the annular plate, thereby driving the transmission rod and blades to move as a whole. The combination of blade rotation and movement enables all-round, multi-angle crushing of the foaming agent between the sealing seat and the sampling port, greatly shortening the dismantling time and improving dismantling efficiency.

[0040] The various components of this invention adopt a modular design, such as the sampling tube, sealing seat, transmission rod, blade, annular plate, telescopic assembly, and power assembly. Each module is relatively independent yet collaborative, facilitating assembly, disassembly, and maintenance. This modular design not only improves the device's production efficiency and reduces production costs but also allows users to easily upgrade and modify the device according to their actual needs. The overall structure of this invention is compact, with a rational layout of components, making full use of limited space. The transmission rod rotates through the outer wall of the sealing seat, the annular plate is rotatably connected to the transmission rod and positioned appropriately, the telescopic assembly is located on the outer wall of the annular plate and connected to the sealing seat, and the power assembly is located on the outer wall of the sampling tube. This compact structural design allows the device to maintain full functionality while being small in size, easy to carry and install, and suitable for sampling scenarios of different scales and types of flues.

[0041] The operation of this invention is highly automated. Users only need to turn on the motor switch to start the entire dismantling process, eliminating the need for complex manual operations. The power unit automatically drives the transmission component, which in turn rotates and moves the blades, achieving the crushing and dismantling of the foaming agent. This automated operation reduces the skill requirements of operators, minimizes the impact of human factors on the dismantling effect, and improves the accuracy and reliability of the operation. From sealing and sampling preparation to the dismantling operation after sampling, the entire process is clear, straightforward, and easy to understand and master. Users only need to follow simple steps to complete the entire flue gas sampling process, improving work efficiency and user experience.

[0042] Furthermore, this invention can adapt to different types and specifications of flue sampling ports, and can achieve good sealing and dismantling effects for both large flues in industrial production and flues in small equipment.
