Embodiment 1

[0028] An energy-saving vibrating screen for two-stage screening, comprising a frame 1, a first sieve plate 2 and a driver 3, the first sieve plate 2 is arranged horizontally and each side is provided with a first retaining protrusion 4, so The first sieve plate 2 is provided with a first discharge trough 5 below the first sieve plate 2, and the first sieve plate 5 is inclined along the length direction of the first sieve plate 2, and the first sieve plate 2 can be The center line of the first sieve plate 2 is rotated to drive the first sieve plate 2 to swing through the driver 3; the second sieve plate 6 extending along the length direction of the first sieve plate 2 is horizontally provided below the first discharge chute 5, and the first sieve plate 6 The mesh number of the plate 2 is greater than the mesh number of the second sieve plate 6, and the second sieve plate 6 is provided with a second retaining protrusion 7 on each side, and the second sieve plate 6 can be arrange...

Embodiment 2

[0038]Based on Example 1, both sides of the first sieve plate 2 in the length direction are provided with a downwardly inclined first inclined plate 9, one side of the first inclined plate 9 is hinged to the first material retaining protrusion 4, so The other side of the first inclined plate 9 extends to the outside of the side wall in the length direction of the first discharge chute 5, so as to further prevent the materials falling from the side of the first sieve plate 2 from falling into the first discharge chute 5 ,

Embodiment 3

[0040] Based on Embodiment 1 and / or 2, a third discharge trough 10 is provided on both sides of the first sieve plate 2, and the third discharge chute 10 is inclined along the length direction of the second sieve plate 6 to pass through the second sieve plate 6. The three discharge troughs 10 collect the materials falling from the side of the second sieve plate 6 so as to collect the materials falling from the sides of the second sieve plate 6 .

[0041] In order to further ensure that the material falling from the side of the second sieve plate 6 slides into the third discharge chute 10, both sides of the second sieve plate 6 in the length direction are provided with second inclined plates 11 inclined downwards, One side of the second sloping plate 11 is hinged to the second protrusion, and the other side of the second sloping plate 11 extends above the third discharge chute 10 .

Abstract

The invention relates to the technical field of material screening, in particular to an energy-saving type two-stage screening vibrating screen. According to the technical scheme, the energy-saving type two-stage screening vibrating screen comprises a rack, a first screen plate and a driver, wherein the first screen plate is horizontally arranged, a first discharging groove is formed below the first screen plate, the first discharging groove is inclined in the length direction of the first screen plate, and the first screen plate can rotate along the center line of the length direction of thefirst screen plate so as to be driven to swing through the driver; and a second screen plate extending in the length direction of the first screen plate is horizontally arranged below the first discharging groove, the mesh number of the first screen plate is larger than that of the second screen plate, second material blocking protrusions are arranged on all sides of the second screen plate, and the second screen plate can rotate along the center line of the length direction of the first screen plate, so as to be driven to swing through materials falling from the side edge of the first screenplate. According to the energy-saving type two-stage screening vibrating screen, two-stage screening of the materials can be realized only by driving one vibrating screen plate to vibrate through onedriver, and the energy-saving type two-stage screening vibrating screen has the characteristics of being high in screening efficiency and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of material screening, in particular to an energy-saving two-stage screening vibrating screen. Background technique [0002] The vibrating screen mainly includes a vibrating motor, a vibrator, a sieve plate and a frame. The motor drives the eccentric block of the vibrator to rotate at a high speed through a V-belt or a coupling, and the centrifugal force generated by the running eccentric block excites the sieve plate to produce a certain amplitude of movement. The material is subjected to the impulse transmitted by the sieve plate on the inclined screen surface to produce continuous throwing motion. When the material meets the sieve surface, the particles smaller than the sieve hole pass through the sieve while the large particle material stays on the sieve surface. Realize the screening of materials. [0003] However, the existing vibrating screens can usually only perform the first screening. For materia...
