Abstract
Description
Technical Field
[0001] The invention relates to a pelletizing disk edge scraping device and a scraping method thereof, and belongs to the technical field of pelletizing production in the metallurgical industry. Background Art
[0002] During the ball making process, the material inside the ball making disk rotates with the ball making disk to complete the steps of mother ball generation, ball growth, and ball formation. Due to the different properties of the materials and the different moisture content of the balls, the particle size of the balls after balling varies, and is concentrated in the particle size range of 8-16mm. Some large and small balls will be thrown out of the disk. Due to the uneven moisture content of the materials and the change in the viscosity of the refined powder of the materials, the materials stick to the edge of the disk, which affects the downward discharge of the finished balls, and then affects the quality and output of the balls, and also causes the wear of the ball making disk equipment.
[0003] The existing disk edge scraper uses a single baffle to clean the disk edge sticky material, and relies on its own gravity to clean in the reverse direction. When the disk edge sticky material causes the disk edge to be uneven, the scraper bounces up and fails to scrape the material, causing a large amount of material to be scattered under the ball disk. In addition, the left and right fixing method is easy to detach from the disk edge and get stuck on the disk edge, causing damage to the side lining of the ball disk. The scraper is made of nylon lining, which has a high hardness, and the edge of the ball-making disk is spliced with arc-shaped nylon linings. When the scraper scrapes the joint, it is easy to cause the disk edge to warp and be damaged. In the production process, the ball disk is used frequently, and the scraper is fixed with perforated screws. Due to the material, the service life is short and it is difficult to replace after wear. The width of the scraper baffle is the same as the width of the disk edge. The iron powder part that rises under the centrifugal force will be thrown out of the ball disk, causing an increase in the wet return rate. Summary of the invention
[0004] The purpose of the present invention is to provide a pelletizing disk edge scraping device and a scraping method thereof, which can clean the accumulated material on the edge of the pelletizing disk in real time, effectively block the material and raw balls moving up with the ball disk, and solve the problems existing in the background technology.
[0005] The technical solution of the present invention is: A pelletizing disk edge scraper device comprises a pelletizing disk, a hanging frame, a rotating shaft, a straight scraper plate pull rod, an inclined scraper plate pull rod, an inclined scraper plate and a straight scraper plate. The inclined scraper plate and the straight scraper plate are sequentially arranged on the edge of the pelletizing disk in the order of scraping. The inclined scraper plate forms a certain angle with the pelletizing disk, and the straight scraper plate is arranged vertically to the pelletizing disk. The inclined scraper plate is connected to the lower end of the inclined scraper plate pull rod through a rib plate, and the upper end of the inclined scraper plate pull rod is rotatably connected to the hanging frame through a rotating shaft. The straight scraper plate is connected to the lower end of the straight scraper plate pull rod through a rib plate, and the upper end of the straight scraper plate pull rod is connected to the hanging frame.
[0006] A vertically arranged straight scraper plate sleeve is fixed on the suspension frame, and the upper end of the straight scraper plate pull rod is inserted into the straight scraper plate sleeve.
[0007] The straight scraper plate sleeve is fixed on the suspension frame through a rib plate.
[0008] The inclined scraper plate is one piece, and the straight scraper plates are two pieces arranged in series.
[0009] The angle between the inclined scraper plate and the pelletizing disk is 15-45 degrees.
[0010] The suspension frame is a frame structure connected by two frame longitudinal beams and a plurality of frame cross beams.
[0011] A pelletizing disk edge scraping method adopts a pelletizing disk edge scraping device as defined above. During the pelletizing process, an inclined scraper plate first scrapes off most of the sticky material on the disk edge by gravity, and then a straight scraper plate cleans the remaining sticky material, thereby cleaning the accumulated material on the disk edge in real time, effectively blocking the material and raw balls that move up with the disk, thereby reducing the return rate of pelletizing.
[0012] The beneficial effects of the present invention are as follows: the present invention can clean up the accumulated materials on the edge of the ball making disk in real time, effectively block the materials and raw balls moving up with the ball making disk, and the wider scraper can also change the path of the rising materials and control the overflow of the materials in the disk, which greatly reduces the labor intensity of the post and effectively reduces the return rate of the ball making.
