Description

Technical Field

[0001] The utility model relates to a distributor, in particular to a nine-roll distributor capable of adjusting the inclination angle, belonging to the technical field of nine-roll distributor equipment. Background Art

[0002] The nine-roll distributor is an important device for distributing materials on a sintering machine in the sintering process. The nine-roll distributor is used in conjunction with a round-roll distributor, and it is the best choice to distribute materials to the inner side of the sintering trolley. The nine-roll distributor is located between the round-roll feeder of the sintering machine and the sintering trolley. Its function is to distribute the sintered and mixed materials transported by the round-roll feeder on the sintering trolley. The nine-roll distributor has the advantages of smooth material distribution, high segregation degree, and convenient maintenance, which is beneficial to improving the output and quality of sintered ore and plays a greater role in reducing sintering energy consumption. Therefore, it is widely used in the sintered and mixed material distribution system of the sintering machine. However, its working condition directly affects the output, product quality, and operation rate of the sintering operation. When working, the whole nine-roll distributor is in an inclined state, and the inclination angle is between 36° and 42°. The center lines of the rollers are arranged in a diagonal line. When the sintering raw materials flow on the roller surface, due to the penetration of the materials, some small-particle materials fall through the gaps between the rollers and land on the upper surface of the trolley. In addition, most of the sintering raw materials fall from the last roller of the nine-roll distributor. The larger the particle material, the faster the movement speed, and the more forward the position it falls to; the smaller the particle material, the slower the movement speed, and the closer it is to the lower part of the nine-roll distributor, which promotes the larger sintering materials to be distributed at the bottom of the trolley and the smaller sintering materials to be distributed at the upper part of the trolley, thus realizing the segregation of the materials. However, due to the change of the output index in the production process, the cloth thickness needs to be adjusted accordingly. However, the angle of the nine-roll distributor is fixed after installation and cannot be changed with the change of the cloth thickness, resulting in the change of the dispersion and segregation degree of the large and small material particles when the materials fall from the last roller, thus affecting the air permeability of the material layer in sintering. It can be seen that the nine-roll distributor that cannot adjust the inclination angle cannot meet the actual production requirements. Therefore, an adjustable nine-roll distributor is needed, which is required to be able to adjust the adaptability angle according to the production requirements, thereby improving the product quality.

Then start the hydraulic cylinder 11 to drive the inclined plate 1 to tilt to the specified angle, and then tighten the clamping pieces 9 again for limiting. Thus, the inclination angle adjustment of the nine-roller cloth distributor is completed.
