Description

Technical Field

[0001] This utility model relates to the technical field of slag discharge pipe equipment, specifically to a boiler slag discharge pipe rapping device. Background Technology

[0002] The development and application of circulating fluidized bed boiler technology have been widely adopted. This technology is one of the advanced technologies for clean coal combustion and achieving sustainable development strategies. It integrates advantages such as energy saving, clean combustion, safety and reliability, and reduced pollution emissions. However, in actual boiler operation, some local structural problems can also affect boiler efficiency. For example, frequent blockage of the boiler ash removal pipe seriously affects the safe and economical operation of the boiler.

[0003] Currently, the most common method for unblocking ash discharge pipes in circulating fluidized bed boilers is to install a ash-poke pipe on top of the ash discharge pipe for manual unblocking when ash becomes blocked. Once the ash discharge pipe is blocked, the conventional method involves personnel manually removing the ash using a ash-poke bar inserted through an inclined ash-poke pipe. This method is physically demanding for on-site operators. Because the furnace of a circulating fluidized bed boiler is under slight positive pressure, there is a risk of high-temperature ash leakage during ash removal, which can easily cause burns and poses a significant safety hazard.

[0004] If a slag removal pipe is not installed on the slag discharge pipe, once the slag discharge pipe becomes blocked, the only option is to wait for the boiler to be shut down and then clear the blockage. On the other hand, frequent blockages may also cause the boiler furnace bed pressure to rise, posing a potential risk of damage to the boiler and downstream equipment of the slag discharge pipe, and increasing equipment maintenance costs and frequency.

[0013] A further technical solution is that the center of the dial has a rotating hole that runs through both sides, and a rotating shaft is horizontally installed inside the rotating hole. The two ends of the rotating shaft are rotatably connected to the cavity walls on opposite sides of the drive cavity, and the output shaft of the drive motor passes through the drive cavity and is connected to the rotating shaft for transmission.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the sliding hole of the fixing rod is aligned with the slag discharge pipe for installation, and the vibrating rod is driven by the driving component to reciprocate to strike the outer wall of the slag discharge pipe, thereby replacing the function of manually striking the slag discharge pipe to unclog the pipe, reducing labor consumption and risk.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Figures 1 to 2 The following is an embodiment of the present invention.

[0020] Example:

[0021] A boiler ash discharge pipe vibrating device includes a fixed rod 1, one end of which has a sliding hole 2. A vibrating rod 3 is slidably installed inside the sliding hole 2, with one end of the vibrating rod 3 outside the sliding hole 2. A drive assembly is installed on the side of the fixed rod 1 to drive the vibrating rod 3 to reciprocate within the sliding hole 2. The device aligns the sliding hole 2 of the fixed rod 1 with the ash discharge pipe, and the drive assembly drives the vibrating rod 3 to reciprocate, causing the vibrating rod 3 to strike the ash discharge pipe. This replaces manual tapping of the ash discharge pipe for unblocking, reducing labor costs and safety risks.

[0022] The drive assembly includes a dial 4 and a drive motor 5 for driving the dial 4 to rotate. One end of the vibrating rod 3, located within the sliding hole 2, is connected to the bottom of the sliding hole 2 via a spring 6. The lower side of the fixed rod 1 has a dialing strip hole 7 communicating with the sliding hole 2 along its length. The dial 4 is vertically positioned below the dialing strip hole 7. Several dial rods 8 are distributed near the edge on one side of the dial 4. A fork 9 is installed at one end of the vibrating rod 3 within the sliding hole 2, and the lower end of the fork 9 protrudes through the dialing strip hole 7 and is positioned between two adjacent dial rods 8. Figure 2As shown, after the drive motor 5 is started, it drives the actuating disk 4 to rotate clockwise. When the actuating disk 4 rotates, the actuating rod 8 on it pushes the fork 9 to move to the right, thereby moving the vibrating rod 3 to the right. Simultaneously, the actuating rod 8, which is in contact with the fork 9, gradually moves downwards, continuously compressing the spring 6 during this movement. When the actuating rod 8 moves away from the lower end of the fork 9, the spring 6 pushes the vibrating rod 3 to the left, striking the slag discharge pipe. After each strike, due to the continued rotation of the actuating disk 4, the next actuating rod 8 pushes the fork 9 to the right again, thus moving the vibrating rod 3 to the right for the next strike. This process is repeated, achieving continuous striking of the slag discharge pipe to clear it.

[0023] A first positioning rod 10 is provided at the bottom of the sliding hole 2, and a second positioning rod 11 is provided at one end of the vibrating rod 3 placed inside the sliding hole 2. The second positioning rod 11 and the vibrating rod 3 can be configured as an integral structure. The two ends of the spring 6 are respectively sleeved on the first positioning rod 10 and the second positioning rod 11. By setting the first positioning rod 10 and the second positioning rod 11, the two ends of the spring 6 can be limited and positioned, avoiding misalignment or twisting of the two ends of the spring 6, which would prevent the spring 6 from performing its reset function properly.

[0024] A drive ring 12 is fixedly installed on the outer wall of one end of the vibrating rod 3, which is placed inside the sliding hole 2. The end of the fork 9 is fixedly connected to the drive ring 12 inside the sliding hole 2, and the outer wall of the drive ring 12 is slidably connected to the hole wall of the sliding hole 2. By setting the drive ring 12, it can be used as a sliding connector between the vibrating rod 3 and the sliding hole 2 to achieve smooth sliding of the vibrating rod 3. At the same time, it can also be used as a connector between the fork 9 and the vibrating rod 3 to connect the vibrating rod 3 and the fork 9.

[0025] A guide ring 13 is installed on the fixed rod 1 at the opening of the sliding hole 2. The center hole of the guide ring 13 is aligned with the opening of the sliding hole 2. The vibrating rod 3 is slidably disposed within the center hole of the guide ring 13, and the diameter of the vibrating rod 3 matches the diameter of the center hole of the guide ring 13. By setting the guide ring 13, it can cooperate with the drive ring 12 to guide the sliding of the vibrating rod 3, thereby improving the smoothness of the sliding of the vibrating rod 3 by reducing the friction between the vibrating rod 3 and the wall of the sliding hole 2.

[0026] The actuating disc 4 is installed below the actuating bar hole 7 via the drive box 14. The drive box 14 is connected to the lower side of the fixed rod 1. The drive box 14 is provided with a drive cavity 15. The actuating disc 4 is installed vertically in the drive cavity 15. The upper side of the drive box 14 is provided with a connecting port 16 that is aligned and connected to the actuating bar hole 7. The lower end of the fork 9 is placed in the drive cavity 15 through the connecting port 16.

[0027] The actuation disk 4 has a centrally located rotating hole 17 extending through both sides. A rotating shaft 18 is horizontally positioned within the rotating hole 17, with its two ends rotatably connected to the opposite walls of the drive cavity 15. The output shaft of the drive motor 5 passes through the drive cavity 15 and is connected to the rotating shaft 18 for transmission. The drive housing 14 facilitates the installation of the actuation disk 4 and also conceals it to prevent accidental operation. The rotating shaft 18 allows the actuation disk 4 to rotate smoothly within the drive cavity 15. After the output shaft of the drive motor 5 passes through the drive cavity 15, it can directly drive the rotating shaft 18 to rotate via a coupling, or it can be driven by various types of gear transmission or gearbox transmission, thereby driving the actuation disk 4 to rotate.

[0028] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
