Detailed Description

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

As shown in figure 1-2, a double-layer desilting vibrating screen comprises a vibrating box body 1, a supporting seat 2 and a vibrating drive source 3, wherein the vibrating box body 1 is obliquely arranged on the supporting seat 2, the upward inclined part receives materials to be screened, the materials are screened and then discharged from one end which is inclined downwards, the vibrating drive source 3 is arranged on the box body, a plurality of screens 4 are arranged in the vibrating box body 1 in parallel, the meshes of the screens 4 are sequentially reduced from top to bottom, the purpose is to screen the materials in a multilayer manner, the materials can be screened more finely, the number of the screens 4 can be set to be 2-5 according to actual needs, the wavy shape of the screens 4 is used for effectively prolonging the screening path of the materials, the materials are screened for a longer time, and the materials are screened more fully, and are prevented from being blocked, the wavy shape of the screens 4 is gentle and wavy, namely the materials are not blocked, the expected screening effect can be achieved, wherein in the plurality of screen meshes 4, the wave-shaped gradient of the upper screen mesh 4 is larger than that of the lower screen mesh 4, and because the material particle diameter of the lower screen mesh is smaller than that of the upper screen mesh, the material blanking is difficult due to the fact that the gradient of the lower screen mesh 4 is too large.
