Description

Technical Field

[0001] This utility model belongs to the field of flue gas heat tracing pipe technology, specifically relating to a flue gas heat tracing pipe cleaning device. Background Technology

[0002] In industrial production, many processes generate flue gas containing a large amount of water vapor and dust. The core function of flue gas heating pipelines is to maintain the flue gas temperature above the dew point through electric or steam heating, preventing acidic gases such as SO2 and NOx from combining with water vapor to form corrosive liquids that could affect monitoring accuracy or damage equipment. Since dust, coal ash, and solid particles carried in the flue gas are prone to deposit in the flue gas flow pipe, long-term accumulation can lead to narrowing of the pipe diameter or even blockage, affecting flue gas flow efficiency. Therefore, high-pressure airflow is often used to quickly blow away these loose impurities and restore the pipeline to its smooth flow. High-pressure air guns are commonly used air blowing cleaning tools, which generally consist of an air gun body, an air inlet connector, a pressure regulating valve, a gun barrel, and a nozzle.

[0003] CN211801699U discloses an air gun, comprising a gun body, a spring, a piston rod, a sealing gasket, a sealing ring, a pin, and a handle. The gun body has, from left to right, interconnected air outlet, mounting hole, connecting hole, and air inlet. A mounting groove is formed on the left side of the bottom end of the gun body. A handle is rotatably connected to the mounting groove via a pin. The upper end of the handle has a groove. A spring is fixedly connected to the top of the mounting hole. A piston rod is mounted at the bottom end of the spring through the mounting hole. An annular sealing gasket is fixedly connected to the upper end of the piston rod, corresponding to the connecting hole. A sealing ring is fixedly connected to the lower end of the piston rod, located within the mounting hole. The bottom end of the piston rod is arc-shaped and presses firmly against the groove at the upper end of the handle. This utility model has a simple and reasonable structure, is easy to use, has low manufacturing cost, and is highly practical.

[0004] Based on the above, some flue gas heating pipelines are curved, making it difficult for the air gun barrel to penetrate deeply. If it is forcibly inserted, it may cause collision damage to the inner wall of the flue gas flow pipe. Therefore, operators can usually only insert the nozzle into the pipe opening for purging. However, since it cannot penetrate into the pipeline, the nozzle diameter is generally small and cannot effectively seal the flue gas flow pipe port. After the high-speed airflow enters the pipe, it is easy to form a gas backflow, causing the dust, crystals and other impurities remaining in the pipe to be sprayed out with the backflow, which poses a risk of impacting the workers' hands or polluting the surrounding environment. Utility Model Content

[0005] To address the aforementioned technical issues, this utility model provides a flue gas heating pipeline cleaning device that can be easily adapted to different structures of heat tracing pipelines and form port seals, supports threaded replacement of various nozzles or switching to conventional shapes, significantly expanding the scope of application, monitors the pipe and pressure gauge to provide real-time feedback on pipeline air pressure, accurately judges the degree of blockage based on pressure changes, effectively improves cleaning efficiency, and combines practicality and flexibility.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A flue gas heating pipeline cleaning device includes an air blowing gun body, an air inlet, an air blowing switch, a first air blowing pipe, a first connecting pipe, a second air blowing pipe, and an alignment and shielding component; the air inlet is fixedly connected to the bottom of the air blowing gun body; the air blowing switch is located on the left side of the air blowing gun body; the first air blowing pipe is fixedly connected to the left side of the air blowing gun body; the first connecting pipe is fixedly connected to the left side of the first air blowing pipe; the second air blowing pipe is fixedly connected to the left side of the first connecting pipe; and the alignment and shielding component is located on the left side of the air blowing gun body.

[0007] Preferably, the alignment shielding assembly includes: a first threaded post and an air blowing hose; the first threaded post is fixedly connected to the left side of the second air blowing pipe; the right end of the air blowing hose is threadedly connected to the first threaded post.

[0008] Preferably, the alignment shielding assembly further includes: a second threaded post and an air nozzle; the second threaded post is fixedly connected to the left side of the air hose; the air nozzle is threadedly connected to the second threaded post.

[0009] Preferably, the alignment shielding component further includes: a first adsorption magnet and a second adsorption magnet; the first adsorption magnet is fixedly connected to the outside of the second air blowing pipe; the second adsorption magnet is magnetically connected to the left side of the first adsorption magnet.

[0010] Preferably, the alignment shielding component further includes: a seal and a connecting groove; the seal is fixedly connected to the left side of the second adsorption magnet; multiple connecting grooves are provided, and the multiple connecting grooves are distributed inside the seal.

[0011] Preferably, the flue gas heat tracing pipeline cleaning device further includes a monitoring component; the monitoring component is disposed above the first connecting pipe.

[0012] Preferably, the monitoring component includes: a monitoring tube and a gas pressure gauge; the monitoring tube is fixedly connected to the first connecting tube; and the gas pressure gauge is fixedly connected to the monitoring tube.

[0013] The beneficial effects of this novel flue gas heat tracing pipeline cleaning device are as follows:

[0014] Firstly, this utility model flue gas heat tracing pipeline cleaning device is equipped with a flexible air blowing hose. By sending the air blowing hose into the flue gas pipeline and connecting the end of the heat tracing pipe through a sealing member connecting groove, it can effectively block the port of the heat tracing pipeline even if the flue gas flow pipe is not in the center of the heat tracing pipeline. Different shaped nozzles can be replaced by threading or the air blowing hose can be removed, so that the air blowing gun body can be changed to a conventional shape, making it more applicable.

[0015] Secondly, the flue gas heating pipeline cleaning device of this utility model is connected to the inside of the first air blowing pipe through the monitoring pipe, and the gas pressure gauge can monitor the gas pressure in the pipeline in real time. When the flue gas pipeline is relatively clean, the pressure data is small, and when the blockage is serious, the pressure data is large due to the poor airflow. The blockage of the flue gas flow pipe can be clearly judged by the pressure change, which effectively improves the cleaning efficiency.

[0016] In summary, this utility model of flue gas heat tracing pipeline cleaning device, through the design of flexible air blowing hose and sealing groove, can easily adapt to heat tracing pipelines of different structures and form port seals. It supports threaded replacement of various nozzles or switching to conventional shapes, significantly expanding the scope of application. The monitoring tube and pressure gauge provide real-time feedback on pipeline air pressure, accurately judging the degree of blockage based on pressure changes, effectively improving cleaning efficiency. Overall, it not only avoids the risk of impurity splashing caused by gas backflow in traditional operations, ensuring the safety of operators, but also achieves in-depth cleaning of curved and complex pipelines through flexible components and modular replacement function, combining practicality and flexibility.

Detailed Implementation

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example 1:

[0026] like Figures 1-5 As shown, this utility model provides a flue gas heating pipeline cleaning device, including an air gun body 1, an air inlet 101, an air switch 102, a first air pipe 2, a first connecting pipe 3, a second air pipe 4, and an alignment and shielding component; the air inlet 101 is fixedly connected to the bottom of the air gun body 1; the air switch 102 is located on the left side of the air gun body 1; the first air pipe 2 is fixedly connected to the left side of the air gun body 1; the first connecting pipe 3 is fixedly connected to the left side of the first air pipe 2; the second air pipe 4 is fixedly connected to the left side of the first connecting pipe 3; and the alignment and shielding component is located on the left side of the air gun body 1.

[0027] The positive shielding component includes: a first threaded post 401 and an air blowing hose 5; the first threaded post 401 is fixedly connected to the left side of the second air blowing pipe 4; the right end of the air blowing hose 5 is threadedly connected to the first threaded post 401.

[0028] The shielding assembly also includes a second threaded post 501 and an air nozzle 6; the second threaded post 501 is fixedly connected to the left side of the air hose 5; the air nozzle 6 is threadedly connected to the second threaded post 501.

[0029] The positive shielding component also includes: a first adsorption magnet 302 and a second adsorption magnet 7; the first adsorption magnet 302 is fixedly connected to the outside of the second air blowing pipe 4; the second adsorption magnet 7 is magnetically connected to the left side of the first adsorption magnet 302.

[0030] The positive shielding component also includes: a seal 701 and a connecting groove 8; the seal 701 is fixedly connected to the left side of the second adsorption magnet 7; multiple connecting grooves 8 are provided, and the multiple connecting grooves 8 are distributed inside the seal 701.

[0031] The working process and usage of this utility model's flue gas heat tracing pipeline cleaning device are as follows: In use, firstly, insert the air nozzle 6 and air hose 5 into the flue gas flow pipe inside the heat tracing pipeline. Then, fit the connecting groove 8 of the sealing member 701 onto the end of the heat tracing pipe. Select the appropriate matching connecting groove 8 according to the different diameters of the heat tracing pipeline. Since the air hose 5 is a flexible connecting pipe, even if the flue gas flow pipe is not located at the center of the heat tracing pipeline, the sealing member 701 can be easily fitted onto the end of the heat tracing pipe. Afterward, activate the air blowing switch 102. Air enters from the air inlet 101 connected to the air inlet pipe, passing through the air gun body 1, the first air blowing pipe 2, the first connecting pipe 3, and the... The second air-blowing pipe 4 and the air-blowing hose 5 are sprayed through the air-blowing nozzle 6 to unclog and clean the flue gas flow pipe. Through the threaded engagement of the second threaded post 501 and the air-blowing nozzle 6, different shapes of air-blowing nozzles 6 can be replaced, such as changing from a conventional straight nozzle to a right-angle nozzle or a fan-shaped nozzle. At the same time, the air-blowing nozzle 6 can be directly threaded to the first threaded post 401, so that the air gun body 1 can be changed to a conventional shape, making it more applicable. The engagement of the first adsorption magnet 302 and the second adsorption magnet 7 can easily remove the seal 701, so that the seal 701 will not obstruct the view when used for other purposes besides cleaning the heat tracing pipe.

[0035] The working process and usage of this utility model flue gas heat tracing pipeline cleaning device are as follows: The monitoring pipe 9 is internally connected to the first air blowing pipe 2, so that the gas pressure passing through the first connecting pipe 3 can be monitored at any time by the gas pressure gauge 901. When the inside of the pipeline is relatively clean, the pressure data displayed by the gas pressure gauge 901 is small. When the inside of the pipeline is severely blocked, the gas flow is not smooth, and the pressure data displayed by the gas pressure gauge 901 is large. Thus, the blockage of the flue gas flow pipe can be clearly judged, thereby improving the cleaning efficiency.
