Problems solved by technology

Due to the determination of the location of the ore stacking site and the installation status of the ore processing system, it is often difficult to ensure that the conveying direction of the installed conveyor belt is consistent with the running direction of the material on the screening machine. It is difficult for the material to be evenly distributed on the screen, resulting in a large area of ​​screen surface being wasted, reducing the screening efficiency and poor screening effect

Embodiment Construction

[0018] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The technical scheme that the present invention takes is, as figure 1 As shown, a kind of ore screening device includes a conveyor belt 20 for feeding to the screening machine and a screen 11 for ore screening. The screen 11 is fixed on the frame 10, and the screen 11 is arranged in an inclined shape. The upper end of the screen 11 is provided with a distributing trough 12, the distributing trough 12 is arranged in an inclined shape and is arranged in sequence with the screen 11, the distributing trough 12 is arranged correspondingly to the discharge end of the conveyor belt 20, and the conveying direction of the conveyor belt 20 is in li...

Abstract

The invention discloses an ore sand screening device which comprises a conveyer belt used for feeding material to a screening machine and a screen used for ore sand screening, wherein the screen is arranged in an inclined manner; a distribution groove is formed in the upper end of the screen and arranged in a manner of being inclined and next to the screen; the distribution groove is arranged corresponding to the discharging end of the conveyer belt; the conveying direction of the conveyer belt intersects with or is perpendicular to the flowing direction of material in the screen; a first flow equalization board component which enables ore sand conveyed by the conveyer belt to be uniformly distributed is arranged at the bottom of the distribution groove; first ore sand outlets are uniformly formed in the first flow equalization board component in the length direction. Through the first flow equalization board component, ore sand conveyed on the conveyer belt can be uniformly distributed on the screen, so that the screening effect and the screening rate can be improved.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to an ore sand screening device. Background technique [0002] The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. The screening machine for mining includes a frame, a screen set on the frame, and a driving mechanism that drives the screen for vibratory screening. The screen surface of the screen is arranged obliquely, and the materials to be screened are introduced from the higher end of the screen. The screened materials of various particle sizes are discharged from the lower end of the screening machine. Due to the determination of the location of the ore stacking site and the installation status of the ore processing sy...
