Description

Gas-to-powder material transport pipeline conveying device Technical Field

[0001] This utility model belongs to the technical field of desulfurization flue gas conveying system for lime kilns, specifically, it relates to a gas conveying pipeline device for transporting powdery materials. Background Technology

[0002] Currently, in the desulfurization agent transportation system of lime kiln flue gas pipeline, the desulfurization agent (powder) is generally transported through a pipe with a bending angle of 90° and a pipe diameter of 80mm.

[0003] However, 90° conveying pipelines have sharp turns, which can easily cause sedimentation, aggregation, and sticking of viscous solid particles. In addition, desulfurization agents (calcium hydroxide) tend to adhere to the pipe walls. Once blocked, it is difficult to clear the blockage in time, which can cause pipeline blockage and thus have a significant impact on normal production and flue gas emissions. Therefore, we propose a gas-to-powder material conveying pipeline device. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0005] A gas-powder material conveying pipeline device includes a conveying pipeline with flanges installed at both ends. An inner tube is installed inside the conveying pipeline. A spring is fixedly connected between the outer wall of the inner tube and the inner wall of the conveying pipeline. A fixing frame is installed on the outer wall of the conveying pipeline. An impact cylinder is installed at the bottom of the fixing frame. The piston rod of the impact cylinder moves through the fixing frame. A top frame is installed at one end of the piston rod of the impact cylinder. A top opening is opened on the outer wall of the conveying pipeline, and the top frame moves through the top opening. A guide ring is provided at the input end of the inner tube. The guide ring is installed on the inner wall of the conveying pipeline, and a sealing ring is installed inside the guide ring. The input end of the inner tube is in close contact with the sealing ring.

[0006] In a preferred embodiment of this utility model, a limiting post is installed on the outer wall of the inner tube, and a groove is opened on the inner wall of the conveying pipe. The limiting post is inserted into the groove, and the spring surrounds the outer wall of the limiting post. By setting the limiting post, the inner tube and the spring can be limited, ensuring the stability of the inner tube and the spring during the compression process.

[0007] In a preferred embodiment of this utility model, the bending angle of the conveying pipe is °.

[0008] In a preferred embodiment of this utility model, top pads are installed at both ends of the top frame. The top pads are made of wear-resistant rubber. By setting the top pads, hard collisions between the top frame and the inner tube can be avoided, thus providing a certain degree of protection for the inner tube.

[0009] In a preferred embodiment of this utility model, a sealing sleeve is movably and tightly fitted on the outer wall of the inner tube near the output end. The sealing sleeve is installed on the inner wall of the conveying pipe. By setting the sealing sleeve, the sealing performance between the inner tube and the conveying pipe can be increased.

[0010] In a preferred embodiment of this utility model, the inner wall of the inner tube is coated with a wear-resistant layer, which is an Al2O3-TiO2 ceramic coating. By setting the wear-resistant layer, the wear resistance of the inner tube can be improved, thereby increasing the service life of the inner tube.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This invention, by setting the bending angle of the conveying pipeline to 135°, allows for smoother fluid flow. Compared to a 90° elbow, it effectively reduces frictional and local resistance, improves fluid conveying efficiency, and reduces energy consumption for conveying gas. This lowers energy costs and the risk of blockage, ensuring the stability of fluid conveying. The 135° bend also effectively reduces the risk of pipeline damage and leakage caused by material impact, guaranteeing the long-term stable operation of the conveying system. It also reduces maintenance and replacement costs due to corrosion. Furthermore, by incorporating an impact cylinder and a top frame, the impact cylinder drives the top frame to impact the inner pipe, causing vibration and effectively dislodging material adhering to the inner wall of the inner pipe. This prevents long-term material adhesion and accumulation inside the inner pipe, ensuring normal material flow within the inner pipe. This design is highly practical.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] As shown in Figures 1 to 5, the gas conveying pipeline device for transporting powdered materials includes a conveying pipeline 1, with flanges 2 installed at both ends of the conveying pipeline 1. An inner pipe 3 is installed inside the conveying pipeline 1, and a spring 6 is fixedly connected between the outer wall of the inner pipe 3 and the inner wall of the conveying pipeline 1. A fixing frame 10 is installed on the outer wall of the conveying pipeline 1, and an impact cylinder 11 is installed at the bottom of the fixing frame 10. The piston rod of the impact cylinder 11 moves through the fixing frame 10, and a top frame 7 is installed at one end of the piston rod of the impact cylinder 11. A top opening 8 is opened on the outer wall of the conveying pipeline 1, and the top frame 7 moves through the top opening 8. A guide ring 13 is provided at the input end of the inner pipe 3, and the guide ring 13 is installed on the inner wall of the conveying pipeline 1. A sealing ring 14 is installed on the inner side of the guide ring 13, and the input end of the inner pipe 3 is in close contact with the sealing ring 14.

[0023] Furthermore, a limiting post 4 is installed on the outer wall of the inner tube 3, and a column groove 5 is opened on the inner wall of the conveying pipe 1. The limiting post 4 is inserted into the column groove 5, and the spring 6 surrounds the outer wall of the limiting post 4.

[0024] The limiting post 4 can limit the movement of the inner tube 3 and the spring 6, ensuring the stability of the inner tube 3 and the spring 6 during compression.

[0025] Furthermore, the bending angle of the conveying pipe 1 is 135°.

[0026] Furthermore, top pads 9 are installed at both ends of the top frame 7, and the material of the top pads 9 is wear-resistant rubber.

[0027] By setting the top pad 9, a hard collision between the top frame 7 and the inner tube 3 can be avoided, thus providing a certain degree of protection for the inner tube 3.

[0028] Furthermore, a sealing sleeve 15 is fitted tightly onto the outer wall of the inner tube 3 near the output end, and the sealing sleeve 15 is installed on the inner wall of the conveying pipe 1.

[0029] By setting a sealing sleeve 15, the sealing performance between the inner pipe 3 and the conveying pipe 1 can be increased.

[0030] Furthermore, the inner wall of the inner tube 3 is coated with a wear-resistant layer 12, which is an Al2O3-TiO2 ceramic coating.

[0031] By setting the wear-resistant layer 12, the wear resistance of the inner tube can be improved, thereby increasing the service life of the inner tube 3.

[0032] The operating principle of the gas-powder material conveying pipeline device is as follows: During operation, setting the bending angle of the conveying pipeline 1 to 135° allows for smoother fluid flow. Compared to a 90° bend, this effectively reduces frictional and local resistance, improves fluid conveying efficiency, and reduces gas energy consumption. This lowers energy costs and reduces the risk of blockages, ensuring stable fluid transport. The 135° bend also effectively reduces the risk of pipeline damage and leakage caused by material impact, ensuring long-term stable operation of the conveying system and reducing maintenance and replacement costs due to corrosion. During use, the impact cylinder 11 is periodically activated, causing the top frame 7 to impact the inner tube 3, resulting in vibration. This effectively dislodges material adhering to the inner wall of the inner tube 3, preventing long-term material buildup and ensuring normal material flow within the inner tube 3. This practical design is highly effective.
