Description

Technical Field

[0001] The invention relates to the technical field of ash hopper cleaning, in particular to an ash hopper cleaning device for grid-refined ash blocks. Background Art

[0002] The ash hopper is a critical component in dust removal equipment. Ash buildup on the hopper wall can be caused by factors such as the moisture content, particle size, temperature, storage age, and the friction coefficient of the hopper's inner wall. Highly viscous ash can adhere to the hopper's inner wall, forming a buildup that is difficult to remove over time. Excessive buildup and poor ash removal require shutdown for maintenance. This requires removing the ash discharge valve and then using tools to clear the ash, a labor-intensive process.

[0003] In the prior art, a Chinese patent with publication number "CN222326117U" discloses a multifunctional ash hopper cleaning device. By rotating the connecting rod connected to both sides of the drive shaft, as well as the guide rod and the sliding sleeve, the two positioning plates and the two cleaning plates can be pressed against the inner walls of ash hoppers of different sizes, thereby making the ash hopper cleaning device more suitable for use. By providing a clamping plate at one end of the two cleaning plates and cooperating with the clamping groove provided on one side of the two positioning plates, the cleaning plates can be conveniently installed or disassembled, thereby allowing the cleaning plates to be replaced, so that the cleaning plates can better clean the accumulated dust on the inner wall of the ash hopper, solving the problem that the cleaning plates in the existing cleaning device cannot be used for ash hoppers of different sizes.

[0004] As described above, the cleaning plate is suitable for ash hoppers of different sizes through the cooperation of the connecting rod, the guide rod and the sliding sleeve. However, in this solution, only the cleaning plate is used to clean the inner wall of the ash hopper. Due to the single friction force and cleaning method of the cleaning plate, it is impossible to effectively break the adhesion between the ash blocks and the inner wall of the ash hopper, resulting in some accumulated dust being difficult to fall off completely, affecting the cleaning effect. In addition, the cleaning plate rubs against the inner wall of the ash hopper for a long time, which easily leads to wear of the cleaning plate, reduces its service life, and may cause a certain degree of damage to the inner wall of the ash hopper.

[0039] Working principle: When in use, the output shaft 8 is driven to rotate by the driving motor 7, and the cross bar 9 on the output shaft 8 is used to drive the cleaning rod 4 to slide on the inner wall of the ash hopper body 1. The cleaning rod 4 is used to clean the ash blocks on the inner wall of the ash hopper body 1. At the same time, when the output shaft 8 rotates, it will drive the driving gear 10 to rotate. The driving gear 10 is engaged with the driven gear 14, and the driven gear 14 will cooperate with the driving shaft 13 through the bearing 12, thereby driving the driving rod 16 on the T-shaped shaft 15 to rotate around the driving shaft 13.

When the pulling rod 17 drives the pushing rod 18 During the horizontal reciprocating movement, the pushing rod 18 is used to cooperate with the pushed groove 28 on the pushed plate 27, so that the pushed plate 27 reciprocates around the rotating shaft 26, and then the tooth plate 33 cooperates with the tooth block group 30 on the driven rod 29, so that the knocking head 6 on the driven rod 29 reciprocates to knock on the surface of the ash hopper body 1. The knocking force generated by the knocking head 6 makes it easy to make the ash blocks on the inner wall of the ash hopper body 1 fall off. When it is necessary to knock on different positions of the ash hopper body 1, the first electric push rod 32 drives the gear The plate 33 moves inward, and the driven rod 29 rotates around the rotating shaft 26. The angle between the driven rod 29 and the pushed plate 27 becomes larger. At the same time, the second electric push rod 35 drives the extension rod 36 to adjust the position of the knocking head 6, so that the knocking head 6 always fits the outer wall of the ash hopper body 1 when adjusting the position. After the knocking head 6 is adjusted, the pushing rod 18 cooperates with the pushed groove 28 on the pushed plate 27, so that the knocking head 6 can knock on the ash hopper body 1, effectively improving the use effect of the ash hopper cleaning device.
