Abstract

The invention relates to an oscillating spiral dry separator applied to the dry separation of fine coal and other fine minerals. The separator mainly comprises a spiral cylinder, an oscillating platform, an oscillating device, a spiral groove bed surface, a chute and a material inlet-outlet nozzle; a double motor is adopted to drive the spiral groove surface to generate the combine movement of oscillation and twisting, and the defects of the current fine coal dry separation are overcome; the generated shearing force separates conglutinated gangue and coal particles between particles and creates the preconditions for density separation; because the spiral groove surface has a radius inclination angle with high outside and low inside, the particles are under the action of inertia force, torsional force, gravitation, friction force and wind force, materials move towards the inner side of the spiral groove while moving upwards along the spiral groove, so that layering and zoning are achieved according to different densities, and therefore, the separation is realized. The equipment has simple structure, novel design conception, stable and reliable separation, significant effect of energy saving and consumption reduction, good separation effect and wide practicality.

Description

technical field

[0001] The invention relates to a vibrating screw dry sorting machine, which is especially suitable for dry sorting of fine-grained coal and also suitable for dry-method sorting of other fine-grained minerals. Background technique

[0002] At present, there are two main types of coal dry separation technology in China: one is the air-dense medium fluidized bed separator developed by China University of Mining and Technology; The FGX type compound dry sorting machine developed on the Internet, and the FX type dry sorting machine developed on the basis of the Russian wind shaker, as well as the CFX type differential wind sorting machine which uses synchronous belt transmission to change the transmission device from this machine. Sorting machine. The first type is to use the gas-solid two-phase to realize the layering and separation of different density granular materials in the fluidized state; the second type is to use the combined effect of wind force and vi...

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the embodiment in the accompanying drawings:

[0014] figure 1 As shown, the vibrating spiral dry separator of the present invention is mainly composed of a spiral cylinder body 2, a vibrating platform 3, a spiral groove bed surface 4, a chute 5 and a feeding nozzle 6. The spiral groove bed surface 4 is arranged on the inner wall of the spiral cylinder body 2, and has a certain longitudinal inclination angle and a transverse inclination angle, and is high on the outside and low on the inside. In the dust collection cover 1, the top of the dust collection cover 1 is provided with an air inlet corresponding to the middle hole surrounded by the spiral groove bed surface 4; The discharge nozzle 6 is provided with an air inlet pipe for supplying air to the bottom of the spiral groove bed surface 4. The bottom end of the spiral cylinder 2 is provided with a ring-shaped vibration platform 3 with an inne...
