Description

Technical Field

[0001] The utility model relates to the technical field of domestic waste incineration treatment equipment, in particular to a high-efficiency ash cleaning device at a boiler economizer outlet. Background Art

[0002] Ash accumulation at the boiler economizer outlet not only affects boiler operating efficiency but can also increase pollutant emissions. Therefore, the development and application of efficient ash removal technologies are crucial. While conventional ash removal devices can reduce ash accumulation to a certain extent, they often suffer from incomplete removal, particularly on the inner wall of the outlet, near the ground. Due to the slope and irregular dimensions of the inner wall, in addition to the normal ash accumulation, a large amount of sediment adheres, making it difficult to clean. This urgently requires improvement. Utility Model Content

[0003] In order to solve the deficiencies of the above-mentioned technologies, the utility model provides a high-efficiency ash cleaning device for a boiler economizer outlet, comprising a driving mechanism and a cleaning mechanism, wherein the driving mechanism is arranged at the bottom of the economizer, and the cleaning mechanism is arranged on the inclined wall of the economizer close to the outlet, the cleaning mechanism is connected to the driving mechanism, the cleaning mechanism comprises a mounting block, a pair of mounting rods, a pair of compression springs and a plurality of cleaning scrapers, the mounting block is provided with a pair of mounting grooves matching the mounting rods, the pair of mounting rods are respectively arranged in the mounting grooves and connected to the mounting grooves by compression springs, the mounting block and the pair of mounting rods are provided with cleaning scrapers, and the mounting block is movably connected to the driving mechanism.

[0004] The above technical solution is adopted, by arranging a cleaning mechanism including a mounting block, a pair of mounting rods, a pair of compression springs and a number of cleaning scrapers on the irregular inclined wall of the economizer outlet. When the driving mechanism drives the mounting block from the bottom of the inclined wall along the inclined wall toward the outlet, the cleaning scrapers arranged on the pair of mounting rods and the mounting block clean the accumulated dust and sediment on the inclined wall. During the movement, the distance between the two side edges of the inclined wall will gradually narrow. At this time, the pair of mounting rods will press against the two side edges of the inclined wall, and slowly retract from the mounting groove under the action of the compression springs to adapt to the change in the distance between the inclined walls, thereby ensuring that the accumulated dust and sediment on the inclined wall are cleaned.

[0005] The utility model is further configured as follows: one end of the pair of mounting rods is provided with an inclined plate that matches the side wall at the economizer outlet, and the cleaning scrapers connected to the mounting rods are provided on the inclined plate.

[0006] By adopting the above technical solution, since one end of the pair of mounting rods is provided with an inclined plate that matches the side wall at the economizer outlet, the cleaning scrapers connected to the mounting rods are all arranged on the inclined plates. By fitting the inclined plates with the two side walls of the inclined wall, the movement and contraction of the pair of mounting rods can be made smoother, thereby ensuring that the cleaning scrapers can fit on the surface of the inclined wall throughout the entire process, thereby successfully completing the cleaning work.

[0007] Further configuration of the utility model: the driving mechanism includes a driving cylinder, a retracted mounting groove and a driving connecting rod, the retracted mounting groove is arranged at the bottom of the economizer, the driving cylinder is arranged in the retracted mounting groove, and the retracted mounting groove is provided with a through hole for the driving cylinder piston rod to pass through, one end of the driving connecting rod is connected to the mounting block and is rotatably matched, and the other end is connected to the piston rod of the driving cylinder.

[0008] The above technical solution is adopted. Since the driving mechanism includes a driving cylinder, a retracted mounting groove and a driving connecting rod, the retracted mounting groove is arranged at the bottom of the economizer, and the driving cylinder is arranged in the retracted mounting groove. The retracted mounting groove is provided with a through hole for the driving cylinder piston rod to pass through. One end of the driving connecting rod is connected to the mounting block and rotated together, and the other end is connected to the piston rod of the driving cylinder. By setting the retracted mounting groove and setting the driving cylinder in the retracted mounting groove, the driving cylinder is actually set outside the economizer, which can prevent the driving cylinder from being affected by the flue gas in the economizer and reducing its service life. Through the rotational cooperation of the driving connecting rod and the mounting block, the driving cylinder can smoothly drive the cleaning mechanism that is not on the same plane with it to operate.

[0009] Further configuration of the present invention: a piston rod protection cover is provided on the side wall of the retracted mounting groove located inside the economizer, the piston rod of the driving cylinder is located in the piston rod protection cover, and an ash baffle is provided at the connection between the driving connecting rod and the piston rod of the driving cylinder.

[0010] By adopting the above technical solution, since a piston rod protection cover is provided on the side wall of the retracted mounting groove located inside the economizer, the piston rod of the driving cylinder is located in the piston rod protection cover, and an ash baffle is provided at the connection between the driving connecting rod and the piston rod of the driving cylinder, which can protect the piston rod of the driving cylinder. At the same time, the ash baffle can further ensure the relative sealing of the position where the piston rod of the driving cylinder enters the interior of the economizer, thereby ensuring the normal operation of the inside of the economizer.

The cleaning mechanism is connected to the driving mechanism. The cleaning mechanism includes a mounting block 3, a pair of mounting rods 4, a pair of compression springs 5 ​​and a number of cleaning scrapers 6. The mounting block is provided with a pair of mounting grooves 7 matching the mounting rods. The pair of mounting rods are respectively arranged in the mounting grooves and connected to the mounting grooves by compression springs. Cleaning scrapers are provided on the mounting block and the pair of mounting rods, and the mounting block is movably connected to the driving mechanism.

[0015] By arranging a cleaning mechanism including a mounting block, a pair of mounting rods, a pair of compression springs and a number of cleaning scrapers on the irregular inclined wall of the economizer outlet, when the driving mechanism drives the mounting block to push from the bottom of the inclined wall along the inclined wall toward the outlet, the cleaning scrapers arranged on the pair of mounting rods and the mounting block clean the accumulated dust and sediment on the inclined wall. During the movement, the distance between the two side edges of the inclined wall will gradually narrow. At this time, the pair of mounting rods will press against the two side edges of the inclined wall, and slowly retract from the mounting groove under the action of the compression springs to adapt to the change in the distance between the inclined walls, thereby ensuring that the accumulated dust and sediment on the inclined wall are cleaned.

[0016] One end of the pair of mounting rods is provided with an inclined plate 8 matching the side wall at the economizer outlet, and the cleaning scrapers connected to the mounting rods are arranged on the inclined plate.

[0017] Since one end of the pair of mounting rods is provided with an inclined plate that matches the side wall at the economizer outlet, the cleaning scrapers connected to the mounting rods are all arranged on the inclined plates. By fitting the inclined plates with the two side walls of the inclined wall, the movement and contraction of the pair of mounting rods can be made smoother, thereby ensuring that the cleaning scrapers can fit on the surface of the inclined wall throughout the entire process, thereby successfully completing the cleaning work.

[0018] The driving mechanism includes a driving cylinder 9, a retracted mounting groove 10 and a driving connecting rod 11. The retracted mounting groove is arranged at the bottom of the economizer. The driving cylinder is arranged in the retracted mounting groove. The retracted mounting groove is provided with a through hole for the driving cylinder piston rod to pass through. One end of the driving connecting rod is connected to the mounting block and is rotated together, and the other end is connected to the piston rod of the driving cylinder.

[0019] Since the driving mechanism includes a driving cylinder, a retracted mounting groove and a driving connecting rod, the retracted mounting groove is arranged at the bottom of the economizer, the driving cylinder is arranged in the retracted mounting groove, and a through hole is opened on the retracted mounting groove for the driving cylinder piston rod to pass through. One end of the driving connecting rod is connected to the mounting block and rotated together, and the other end is connected to the piston rod of the driving cylinder. By setting the retracted mounting groove and setting the driving cylinder in the retracted mounting groove, the driving cylinder is actually set outside the economizer, which can prevent the driving cylinder from being affected by the flue gas in the economizer and reducing its service life. Through the rotational cooperation of the driving connecting rod and the mounting block, the driving cylinder can smoothly drive the cleaning mechanism that is not on the same plane with it to operate.

[0020] A piston rod protection cover 12 is provided on the side wall of the retracted mounting groove located inside the economizer, the piston rod of the driving cylinder is located in the piston rod protection cover, and an ash baffle 13 is provided at the connection between the driving connecting rod and the piston rod of the driving cylinder.

At the same time, the ash baffle can further ensure the relative sealing of the position where the piston rod of the driving cylinder enters the interior of the economizer, thereby ensuring the normal operation of the inside of the economizer.
