The pneumatic ash conveying pipeline is needed in the flue gas treatment stage of the desulfurization device and the circulating ash conveying to the desulfurization bin for recycling. The existing ash conveying pipeline of the desulfurization device does not have a self-cleaning function. During the conveying process of the pneumatic ash conveying pipeline, the pipeline system is sometimes blocked due to the foreign matter in the pipeline, which causes the pneumatic ash conveying pipeline to fail to operate normally, and the blocked position cannot be determined. A large amount of pipeline needs to be removed when cleaning the foreign matter, which is time-consuming and laborious.

[0031] To solve the above problems, please refer to Figure 1 and Figure 2 The utility model provides a kind of ash conveying pipeline 1000, including first pipeline 1, second pipeline 2 and connecting pipeline 3, the both ends of the extension direction of connecting pipeline 3 are respectively with first pipeline 1 and second pipeline 2 detachably connected, and the inner wall of connecting pipeline 3 is detachably connected with anti-blocking piece 4, and anti-blocking piece 4 is arranged to face the flow direction of material in connecting pipeline 3, and anti-blocking piece 4 and connecting pipeline 3 form passage for material to pass through, and anti-blocking piece 4 has blocking surface for blocking foreign matter in ash conveying pipeline 1000.

[0032] The technical scheme of the utility model sets detachable connecting pipeline 3 in ash conveying pipeline 1000, and sets anti-blocking piece 4 in connecting pipeline 3, blocks foreign matter in ash conveying pipeline 1000 by anti-blocking piece 4 to make it stay in connecting pipeline 3, to prevent foreign matter from continuing to move in ash conveying pipeline 1000, in addition, detachable connecting pipeline 3 and anti-blocking piece 4 can facilitate the removal of foreign matter, so that the irregular movement of foreign matter in ash conveying pipeline 1000 can be avoided, the time spent in checking the position of foreign matter is reduced, and the foreign matter in ash conveying pipeline 1000 can be conveniently removed, to ensure the normal operation of ash conveying pipeline 1000.

[0033] In an optional embodiment, referring to Figure 1 and Figure 2 To balance the flow of material and block impurities in the connecting pipe 3, the cross-sectional shape of the anti-blocking piece 4 is designed as a cross structure or a mesh structure. In actual installation, the size of the hole enclosed by the anti-blocking piece 4 and the connecting pipe 3 needs to ensure that the ash in the ash conveying pipe 1000 can pass smoothly, while impurities larger in volume than the ash can be blocked and retained by the anti-blocking piece 4. The specific design can be made according to the actual size of the ash and impurities. The cross structure or mesh structure of the anti-blocking piece 4 increases the surface area in contact with the material, improves the blocking effect, and at the same time allows the material to flow around the anti-blocking piece 4, reducing the retention of the material in the pipe. This design also helps to disperse the impact force of the material on the anti-blocking piece 4, reducing wear and tear and prolonging the service life of the anti-blocking piece 4. In addition, the mesh structure design can provide more uniform material flow, reducing friction and wear of the material in the pipe and prolonging the service life of the pipe. The cross structure can provide structural stability while maintaining the smoothness of the inside of the pipe. This diversified design improves the adaptability and reliability of the ash conveying pipe 1000, making it suitable for different material properties and flow conditions.

The cooperation of the fixing part 31 and the connecting part improves the stability of the anti-blocking piece 4, and also facilitates the installation and replacement of the anti-blocking piece 4. By reasonably distributing the fixing parts 31 and the connecting parts, the impact force of the material on the anti-blocking piece 4 can be reduced, the pressure change inside the pipe can be reduced, and the stability and safety of the entire ash conveying system can be improved. While maintaining its blocking function, it reduces interference with the flow of material, ensuring the continuity and uniformity of the flow of material.

In the actual installation process, the anti-blocking piece 4 can be arranged on the fixed part 31 facing the direction of the material flow, so that the anti-blocking piece 4 and the fixed part 31 are arranged in abutment, and the anti-blocking piece 4 is further abutted against the fixed part 31 by the impact of the material in the connecting pipeline 3, so that the installation of the anti-blocking piece 4 can be realized. In this embodiment, in order to further prevent the anti-blocking piece 4 from shaking in the connecting pipeline 3 and improve the stability of the anti-blocking piece 4, the clamping groove 311 is arranged on the fixed part 31, so that the anti-blocking piece 4 can be quickly and accurately installed at the predetermined position of the inner wall of the connecting pipeline 3. The use of the clamping groove 311 simplifies the installation process, reduces the installation time, and improves the stability of the anti-blocking piece 4 in the pipeline. During the material flow, the clamping groove 311 can prevent the connecting part from falling off or shifting, and ensure that the anti-blocking piece 4 always maintains the correct blocking position. In addition, the design of the clamping groove 311 also helps to improve the sealing of the pipeline system, prevent material leakage, reduce environmental pollution and material loss.

In the actual design process, the elastic member 43 can be a spring, or a structure with an elastic deformation amount such as a rubber pad, which is fixed by compressing the elastic member 43 against the telescopic rod 42. In this embodiment, in order to facilitate the maintenance and replacement of the elastic member 43, a spring is used as the elastic member 43. The spring provides a simple and effective elastic support, so that the anti-blocking member 4 can adapt to the slight changes of the inner wall of the pipeline, and maintain close contact with the inner wall of the connecting pipeline 3. The use of the spring also helps to absorb the impact force generated during the flow of the material, reducing the wear and tear on the anti-blocking member 4 and the inner wall of the connecting pipeline 3. In addition, the elasticity of the spring can cause the anti-blocking member 4 to deform when it is pressed by the material, so that it can recover to its original state after the material flows, reducing the possibility of blockage by impurities. This configuration improves the anti-blocking ability of the ash conveying pipeline 1000, ensuring the normal operation of the desulfurization device. The addition of the spring also simplifies the installation and adjustment process of the anti-blocking member 4, improving the maintenance efficiency of the entire system.
