Description

Technical Field

[0001] The utility model relates to the technical field of material separation, in particular to a conical surface rotary triboelectrostatic separator device. Background Technique

[0002] Gangue is a coal-bearing sedimentary rock formed during the coal formation process, composed of substances such as mudstone and sandstone. A large amount of gangue is generated during coal mining and separation. Gangue contains a certain amount of carbon, and according to different sources and treatment methods, its content is usually between 10% and 20%. Extracting residual carbon from gangue has the advantages of cheap and easily available raw materials, high product added value, and wide industrial chain coverage, and is attracting more and more attention from coal mines and their downstream enterprises. Efficiently extracting and utilizing the residual carbon in gangue is an important direction for the high-value utilization of coal-based solid waste, which will effectively alleviate the contradiction between the shortage of mineral resources and the huge demand in China, and is of great significance for achieving "carbon peak and carbon neutrality". In order to...

[0003] The triboelectrostatic separation method belongs to the electrostatic separation technology and is based on the difference in the electrical properties between particles, that is, the large difference in the dielectric constant and conductivity between the organic matter (coal) and most minerals in gangue for separation. Under the action of a high-speed air flow, fine-grained (particle size less than 74μm) gangue is carried into the friction electrifier, and after experiencing impacts between the friction substances and particles, it is sent into a strong electric field formed by two parallel plates. Since the dielectric constant and conductivity of coal particles are much lower than those of mineral particles, the ejected coal particles are positively charged and the mineral particles are negatively charged. Therefore, under the action of the strong electric field, the coal particles and mineral particles will be attracted to different plates (or collected by corresponding dust collectors) to achieve the purpose of separation. Therefore, a conical surface rotary triboelectrostatic separator device is designed to separate the coal in gangue by using the difference in the surface electrical properties of different components in gangue particles, so as to achieve the purpose of hierarchical utilization.

[0026] During use, by setting the rotation driving member 16, the first driving gear 17 is driven to rotate;

[0027] A base frame 21 is provided on the surface of the vertical plate 7. A second driving gear 19 is rotatably installed at the top end of the base frame 21. A first driven gear 18 is fixed at the central position of the top end of the second driving gear 19. A first driving gear 17 is rotatably installed at the top end of the base frame 21 on one side of the first driven gear 18. The first driving gear 17 meshes with the first driven gear 18.

When the coal gangue is injected between the moving cone 5 and the static cone 4 through the feed pipe 6, the friction effect of the moving cone 5 and the static cone 4 on the coal gangue can be improved. Finally, the coal gangue material after friction is fully triboelectrically charged and falls into the electrostatic separation body 2 below the static cone 4. Due to the arrangement of the negative high-voltage electrostatic separation plate 13 and the positive high-voltage electrostatic separation plate 14, and a conical seat 15 is arranged at the bottom of the electrostatic separation body 2, the clean coal can be attracted and electrostatically separated to the left side of the conical seat 15 and discharged through the opening at the bottom of the electrostatic separation body 2, and the tail coal can be attracted and electrostatically separated to the right side of the conical seat 15 and discharged through the opening at the bottom of the electrostatic separation body 2, thus completing the use of the friction electrostatic separation device.
