Description

A fly ash inlet pipe with a support structure Technical Field

[0001] This utility model relates to the field of fly ash inlet pipeline technology, specifically a fly ash inlet pipeline with a support structure. Background Technology

[0002] Fly ash feed piping refers to the piping system that transports fly ash from the collector to the furnace. Fly ash mainly consists of tiny ash particles produced during fuel (primarily coal) combustion, with particle sizes generally between 1 and 100 μm. The transportation and treatment of fly ash is a significant environmental issue, as improper handling can lead to secondary environmental pollution.

[0003] A furnace inlet pipe with a support structure, as disclosed in publication number CN 218599744 U, includes a branch pipe and a furnace inlet pipe connected to each other by flanges at one end. A positioning seat is welded to one side of the outer wall of the branch pipe, and a clamping seat is welded to one side of the outer wall of the furnace inlet pipe. A traction rod is provided between the clamping seat and the positioning seat. A fixing hole is opened in the inner wall of the positioning seat, and a limit port is opened in the inner wall of the clamping seat. Both ends of the traction rod are fixed to the inner walls of the fixing hole and the limit port, respectively. In use, the traction rod is fixed by bolts and the fixing hole opened in the outer wall of the positioning seat. After the traction rod is fixed, the hook is hung on the inner wall of the limit port of the clamping seat. After the hook is fixed, the adjusting frame is threadedly connected to the hook. After the adjusting frame is threadedly connected, the traction rod is tightened by rotating it. When the traction rod is tightened, it provides support. This solves the problem that when the pipeline is transporting exhaust gas, the vibration and shaking will cause the connection to loosen over time, affecting the connection strength between the pipelines.

[0004] However, the above-mentioned furnace inlet pipes still have some shortcomings in use. The support effect on the pipes is poor, and they cannot be stably supported. Furthermore, the support components cannot be adjusted, making them unsuitable for pipe installation in various environments. In addition, it is not convenient to sample and test the concentration and composition of fly ash inside the pipes, and it is impossible to carry out further processing based on the concentration and composition of fly ash, making them inconvenient to use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a fly ash inlet pipe with a support structure, which solves the problems of poor pipe support, inability to provide stable support, non-adjustable support components, inapplicability to pipe installation in various environments, inconvenience in sampling and testing the concentration and composition of fly ash inside the pipe, and inability to perform further processing based on the concentration and composition of fly ash, making it inconvenient to use.

[0006] This utility model provides the following technical solution: a fly ash inlet pipe with a support structure, including a fly ash pipe, a sampling component is provided on the surface of the fly ash pipe, three support rods are movably connected to the surface of the fly ash pipe, the three support rods are arrayed on the outer surface of the fly ash pipe, a support tube is slidably sleeved on the surface of each support rod, a movable groove is opened on the surface of each support tube, a locking rod is slidably sleeved inside the movable groove, a row of locking grooves matching the locking rod is opened on the surface of each support rod, and a first spring is sleeved on one end of the outer side of each locking rod.

[0007] Preferred technical solution 1: The sampling component includes a sampling tube connected to the fly ash tube. The sampling component includes two through holes opened on the surface of the fly ash tube. A connecting rod is slidably sleeved inside each of the two through holes. A connecting plate is fixedly connected between the two connecting rods at their ends inside the fly ash tube. A sealing plug is fixedly connected to the surface of the connecting plate. A second spring is sleeved on the outer end of each of the two connecting rods.

[0008] Preferred technical solution 2: The sealing plug is in the shape of a cone-shaped frustum, and the sealing plug and the sampling tube are interference-fitted.

[0009] Preferred technical solution 3: Each of the support tubes is movably connected to a mounting plate at its bottom end, and each mounting plate has multiple mounting holes on its surface.

[0010] Preferred technical solution four: Both ends of the fly ash pipe are fixedly installed with connecting flanges.

[0011] Preferred technical solution five: Both of the two through holes are surrounded by sealing rings on one side inside the fly ash pipe, and the two sealing rings are respectively matched with the two connecting rods, and the two connecting rods can slide inside the two sealing rings.

[0012] Compared with the prior art, this utility model provides a fly ash inlet pipe with a support structure, which has the following advantages: In use, the fly ash pipe is connected to other equipment through a connecting flange. Then, by pulling the locking rod outward, it is disengaged from the slot on the support rod, thereby releasing the locking of the support rod. Then, the overall length of the support rod and support pipe can be adjusted so that the mounting plate can be installed in a suitable position. Then, the locking rod is released so that it is inserted into the slot under the elastic force of the first spring to lock the support rod. Then, the mounting plate is fixedly installed in a suitable support position through the mounting hole, which facilitates the support of the fly ash pipe and makes it more stable. When it is necessary to clean the fly ash inside the fly ash pipe... When sampling and testing fly ash, pushing the two connecting rods inward causes the sealing plug to detach from the sampling tube, exposing the sampling tube. The fly ash inside can then flow out through the sampling tube for sampling. After sampling, releasing the connecting rods allows them to return to their original position under the force of the second spring, causing the sealing plug to seal the sampling tube. Pulling the connecting rods outward can also make the sealing plug and sampling tube have an interference fit, resulting in a better sealing effect. This pipe can be quickly installed and is stably supported by multiple components, making it more secure and preventing loosening or falling off due to vibration during use. It also allows for rapid sampling and testing of the fly ash inside. Attached Figure Description

[0017] Please refer to Figure 1-3.

[0018] Example 1: A fly ash inlet pipe with a support structure includes a fly ash pipe 1, a sampling component 2 is provided on the surface of the fly ash pipe 1, three support rods 3 are movably connected to the surface of the fly ash pipe 1, the three support rods 3 are arrayed on the outer surface of the fly ash pipe 1, a support tube 4 is slidably sleeved on the surface of each support rod 3, a movable groove 5 is opened on the surface of each support tube 4, a locking rod 6 is slidably sleeved inside the movable groove 5, a row of locking grooves 7 matching the locking rod 6 is opened on the surface of each support rod 3, and a first spring 8 is sleeved on one end of the outer side of each locking rod 6.

[0019] Example 2: The difference between this example and Example 1 is that the sampling component 2 includes a sampling tube 9 connected to the fly ash tube 1. The sampling component 2 includes two through holes 10 on the surface of the fly ash tube 1. A connecting rod 11 is slidably sleeved inside each of the two through holes 10. A connecting plate 12 is fixedly connected between the two connecting rods 11 at one end inside the fly ash tube 1. A sealing plug 13 is fixedly connected to the surface of the connecting plate 12. A second spring 14 is sleeved on the outer end of each of the two connecting rods 11 to facilitate sampling and testing of the fly ash inside the fly ash tube 1.

[0020] Example 3: The difference between this example and Example 1 is that the sealing plug 13 is in the shape of a cone-shaped frustum, and the sealing plug 13 and the sampling tube 9 are interference-fitted to facilitate sealing of the sampling tube 9.

[0021] Example 4: The difference between this example and Example 1 is that each support pipe 4 is movably connected to a mounting plate 15 at its bottom end. Each mounting plate 15 has multiple mounting holes 16 on its surface, which facilitates fixing the mounting plate 15 in a suitable support position and supports the fly ash pipe 1.

[0022] Example 5: The difference between this example and Example 1 is that both ends of the fly ash pipe 1 are fixedly installed with connecting flanges 17, which facilitates the connection of the fly ash pipe 1 with other equipment.

[0023] Example 6: The difference between this example and Example 1 is that, in this example, sealing rings 18 are provided around one side of the two through holes 10 inside the fly ash pipe 1. The two sealing rings 18 are respectively matched with the two connecting rods 11. The two connecting rods 11 can slide inside the two sealing rings 18, so that the sealing effect of the sampling component 2 is better and the fly ash leakage is prevented.

[0024] In summary, this fly ash inlet pipe with a support structure is used by connecting the fly ash pipe 1 to other equipment via the connecting flange 17. Then, by pulling the locking rod 6 outwards to disengage it from the slot 7 on the support rod 3, the locking of the support rod 3 is released. The overall length of the support rod 3 and support pipe 4 can then be adjusted so that the mounting plate 15 can be installed in a suitable position. Next, the locking rod 6 is released so that it inserts into the slot 7 under the elastic force of the first spring 8 to lock the support rod 3. Finally, the mounting plate 15 is fixedly installed in a suitable support position through the mounting hole 16, facilitating support for the fly ash pipe 1 and making it more stable. When it is necessary to sample and test the fly ash inside the fly ash pipe 1, the... Pushing the two connecting rods 11 inward causes the sealing plug 13 to disengage from the sampling tube 9, exposing the sampling tube 3. The fly ash inside can then flow out through the sampling tube 9 for sampling. After sampling, release the connecting rods 11, allowing them to return to their original position under the elastic force of the second spring 14. This causes the sealing plug 13 to seal the sampling tube 9. The connecting rods 11 can be pulled outward to ensure an interference fit between the sealing plug 13 and the sampling tube 9, resulting in a better sealing effect. This pipe can be installed quickly during use and is supported by multiple components to ensure stability and prevent loosening or falling off due to vibration during use. It also allows for rapid sampling and testing of the fly ash inside.
