Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ore washing and screening, in particular to a compressed air ore washing vibrating screen. BACKGROUND

[0002] Vibrating screens are widely used in the classification process of solid particles in various industrial productions. Vibrating screens can be generally divided into circular vibrating screens and rectangular vibrating screens in terms of shape. Circular vibrating screens are simple in mechanism and are suitable for the classification of small-flow materials. Rectangular vibrating screens can be made into large-area devices and can process large-flow materials. Ore washing vibrating screens are screening devices widely used in the field of mining and mainly consist of a screen box, a vibrating motor and a spring. The screen box is usually made of high-strength steel to ensure firmness and durability. The screen mesh has different mesh counts and materials according to requirements. The vibrating motor generates exciting force to make the materials vibrate on the screen surface. The materials smaller than the screen holes pass through the screen mesh to become undersize materials, and the materials larger than the screen holes are discharged from the screen surface.

[0003] The patent application with the publication number CN112090732A discloses a compressed air ore washing vibrating screen, which comprises a fixed frame, a conveying device arranged in the fixed frame, a sticky material outlet arranged at the end of the conveying device, a receiving hopper supported upward by the fixed frame, the conveying device being communicated upward with the receiving hopper, a box body connected upward with the fixed frame, the box body being communicated downward with the receiving hopper, a screen plate arranged at the bottom of the box body, a feed inlet connected with one end of the box body and a target material discharge outlet connected with the other end of the box body, a vibration exciter fixedly connected with the outer wall of the box body, a wind nozzle fixing plate arranged in the box body above the screen plate, a main air pipe arranged in the box body above the wind nozzle fixing plate, the main air pipe being connected with an air inlet pipe, a plurality of wind nozzles connected downward with the wind nozzle fixing plate, the wind nozzles being uniformly distributed on the wind nozzle fixing plate, and the air outlet directions of the wind nozzles being perpendicular to the screen plate and facing the screen plate.

[0004] The above patent can efficiently separate target materials and sticky materials. However, the ore carries sticky materials, the passing capacity of the sticky materials is poor, and even the screen mesh is quickly blocked to completely lose the separation function of the vibrating screen. The separation of fine particles of materials containing clay is difficult to achieve under the condition of high moisture. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a compressed air ore washing vibrating screen to solve the problems in the background art.
