Multi-level filtering vibrating screen

Abstract

The invention discloses a multi-level filtering vibrating screen. The multi-level filtering vibrating screen comprises a screen box. The screen box inclines for a certain degree and is arranged on a support. The upper end of the screen box is provided with a feed port, and the lower end of the screen box is provided with a discharge port. The back of the screen box is provided with a vibrating motor. A screen net in the screen box is of a multi-level step structure from the top end to the lower end in sequence. The lower portion of each step of the screen net is provided with a guiding pipe, and the lower end of each guiding pipe is located in a collecting box. The multi-level filtering vibrating screen is simple in structure and reasonable in design. In the vibrating and screening process, materials can move from the upper end to the lower end, the materials with different particles can be screened, and the screening function of an ordinary vibrating screen is greatly expanded.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a vibrating screen for multi-stage filtration. Background technique [0002] The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface. Most of the vi...

Problems solved by technology

Most of the vibrating screens sold in the market are linear motion vibrating screens. The screen surface has an inclination angle. Put the material to be screened, and with the vibration of the vibrating motor, the material moves from one end to the other while being screened. At present, this The screen size of this kind of vibrating screen is relatively simple, and the screening of different particle sizes cannot be completed at one time.
