[0002] In steelmaking, fly ash is mainly used to regulate furnace temperature, promote slag formation in the furnace and regulate the balance of chemical reactions in the furnace. After the fly ash is produced into a block structure, the fly ash blocks are generally crushed before use to form fly ash powder. Compared with fly ash blocks, fly ash powder has the advantages of fast reaction speed, uniform mixing with materials and reduced loss. The fly ash blocks are mainly crushed by a crushing mechanism. At present, there is a crushing mechanism. When it is working, the fly ash blocks are first crushed by a crushing roller and then crushed by a rolling roller. In this way, the fly ash blocks can be powdered. However, when the rolling roller is rolling the crushed fly ash, the fly ash powder often sticks to the surface of the rolling roller, which not only affects the normal operation of the rolling roller, but also causes the loss of fly ash.

[0016] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, unless there is a conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1-4 As shown, the lime block crushing device described in this embodiment includes a crushing box body, and the crushing box body 1 is divided into a first crushing area 1a and a second crushing area 1b by a partition 2. A conveyor belt 3 is provided at the bottom of the crushing box body 1, and a feeding gap is provided between the partition 2 and the bottom of the crushing box body 1. The conveyor belt 3 crosses the two crushing areas along the feeding gap. A discharge port 1c is provided on the right side of the second crushing area 1b, and the conveying end of the conveyor belt 3 extends to the outside of the crushing box body 1 along the discharge port 1c. A feed port 1d is provided on the crushing box body 1 at a position corresponding to the top of the first crushing area 1a, and crushing rollers 4 are symmetrically provided at a position below the corresponding feed port 1d in the crushing box body 1. The surfaces of the crushing rollers 4 on both sides are evenly distributed with a number of crushing thorns 4a that work in conjunction with each other. A crushing roller 5 is provided at a position corresponding to the conveyor belt 3 in the second crushing area 1b. A support roller 6 is also provided at a position corresponding to the crushing roller 5 in the conveyor belt 3. The crushed white ash passes between the crushing roller 5 and the conveyor belt 3. The support roller 6 supports the conveyor belt 3 and cooperates with the crushing roller 5 to crush the white ash blocks. A roller cleaning mechanism is also provided at a position corresponding to one side of the crushing roller 5 in the second crushing area 1b. A dust removal cover 7 is also provided at a position corresponding to the crushing roller 5 in the second crushing area 1b. A dust removal pipe 8 extending to the outside of the crushing box 1 is provided on the dust removal cover 7.

[0019] Preferably, a feed hopper is provided at the feed inlet 1d.

[0020] A transmission gear 9 is provided on one side of the shredder roller 4, and the transmission gears 9 on the shredder rollers 4 on both sides are engaged with each other. A motor 10 is provided on the outside of the shredder box 1 at a position corresponding to the outside of any shredder roller 4. The drive shaft of the motor 10 is connected to the roller shaft of the shredder roller 4. The motor 10 rotates one of the shredder rollers 4. Since the transmission gears 9 on the shredder rollers 4 on both sides are engaged with each other, it will control the shredder rollers 4 on both sides to rotate together, and the two shredder rollers 4 rotate in opposite directions.

[0021] A guide edge 11 is provided at the feed port 1d of the first crushing zone 1a. The guide edge 11 is located above the crushing rollers 4 on both sides. The guide edges 11 on both sides extend downward toward the gap between the two crushing rollers 4. The guide edge 11 guides the lime blocks entering the first crushing zone 1a, so that the lime blocks can smoothly enter between the two crushing rollers 4 for crushing.

[0022] A paving plate 20 is provided at the lower end of the partition 2. A gap is provided between the lower end of the paving plate 20 and the conveyor belt 3. The paving plate 20 is also inclined. The white ash crushed by the crushing roller 4 can be flattened by the paving plate 20 when passing through the paving plate 20, thereby facilitating subsequent rolling work.

[0023] The roller cleaning mechanism includes a mounting horizontal plate 12 arranged on one side of the rolling roller 5, and an automatically retractable movable plate 13 is provided on the mounting horizontal plate 12. The movable plate 13 is provided with a scraper handle 14 on the side facing the rolling roller 5, and the scraper handle 14 is provided with a scraper 15 that is fitted with the surface of the rolling roller 5.

[0024] The mounting cross plate 12 is provided with mounting posts 16 on both sides thereof, and a telescopic spring 17 is sleeved on the mounting post 16. A limit head 18 is also provided at the end of the mounting post 16. Both ends of the movable plate 13 are plugged into the mounting posts 16, and one end of the telescopic spring 17 rests on the mounting cross plate 12, and the other end of the telescopic spring 17 rests on the movable plate 13.

[0025] When the scraper 15 is in contact with the surface of the rolling roller 5, the movable plate 13 will squeeze the telescopic spring 17. As the crushing work continues, the end of the scraper 15 will be worn. Once wear occurs, a gap will be generated between the scraper 15 and the rolling roller 5. Under the action of the squeezed telescopic spring 17, it will move toward the movable plate 13 along the mounting column 16 toward the side of the rolling roller 5, so that the scraper 15 can continue to be in contact with the surface of the rolling roller 5. In this way, automatic compensation of the scraper 15 is achieved, which not only extends the service life of the scraper 15, but also eliminates the tedious operation of adjusting the position of the scraper 15, bringing great convenience to production.

[0026] A dust removal fan 19 is provided on the dust removal pipe 8 .

[0027] The working principle of the present invention is as follows: first, the lime blocks are added into the first crushing area 1a in the crushing box 1 through the feed port 1d, and the lime blocks are guided by the guide 11 to fall to the position between the two crushing rollers 4, and the motor 10 drives the crushing rollers 4 to rotate, thereby squeezing the fallen lime blocks, so that the lime blocks are squeezed into small pieces, and the crushed lime blocks fall onto the conveyor belt 3, and the fallen lime blocks are transported to the second crushing area 1b through the conveyor belt 3. When the squeezed and crushed lime blocks pass through the paving plate 20, the paving plate 20 will flatten the lime blocks so that they are spread flat on the surface of the conveyor belt. Then the flattened lime blocks pass through the rolling roller 5. As the rolling roller 5 rotates, it will roll the crushed lime blocks, thereby rolling the lime blocks into lime powder. The rolled lime powder is discharged outward along the discharge port 1c. During the operation of the rolling roller 5, the scraper 15 scrapes the surface of the rolling roller 5 to scrape off the lime stuck on its surface.

[0028] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
