Motivation.
Fig. 2 shows the side wall 12 of vibrating screener 10 shown in FIG. 1, screen assemblies 20, compression assembly 22 and supports
Component 14.The frame 24 of screen assemblies 20 includes side member 28.Side member 28 forms flange.
As described above, compression assembly 22 is installed to wall member 12.The telescopic member 32 shown keeps screen assemblies 20
For concave shape.There is material to be separated to be directly placed on the top surface of screen assemblies 20.Still as described above, screen assemblies
Bottom surface may include matching surface.The bottom surface of screen assemblies 20 directly with 30 phase of matching surface of concave support surface 14
Interaction, so that screen assemblies 20 are for example via concave support surface 14 and by the vibration from accelerator 18.
It the top surface of screen assemblies 20 is arranged to concave shape provides be used for the capture and concentration of material.In sieve group
The concentration of material stream prevents material to be detached from screening surface and the previously separated material of potential pollution and/or cause to tie up on part 20
Repair problem.For biggish Flow of Goods and Materials volume, screen assemblies 20 can be placed as under larger compression, thus in top table
Increase the amount of arc on face and bottom surface.The amount of arc is bigger in screen assemblies 20, and the material of screen assemblies 20 is allowed to retain energy
Power is bigger, and prevents material from overflowing from the edge of screen assemblies 20.
Fig. 3 shows the screen assemblies 20 in undeformed state.Telescopic member 32 is in retracted position.When scalable
When component 32 is in retracted position, screen assemblies 20 can be replaced easily.Screen assemblies 20 are placed on vibrating screener 10
In, so that side member 28 contacts the inclined surface 36 of central member 16.When replaceable screen assemblies 20 are in undeformed state,
Telescopic member 32 is contacted with screen assemblies 20.Inclined surface 36 prevents side member 28 from deflecting towards upward direction.When compression fills
When setting 22 and being activated, telescopic member 32 is stretched out from compression assembly 22, so as to cause between telescopic member and inclined surface 36
Aggregate level distance reduce.With the reduction of total level distance, each screen assemblies 20 towards in downward direction 29 deflection to
It contacts support surface 30 (as shown in Figure 2).Inclined surface 36 is further positioned so that screen assemblies 20 with arc structure appropriate peace
In vibrating screener 10.Extendible Extent based on telescopic member 32 can provide different arc structures.Alternatively,
Screen assemblies 20 may include rigid frame, so that it is indeformable under compression force.The extension of telescopic member 32 is logical
It crosses the constant spring pressure for the main body for resisting compression set 22 and realizes.The contraction of telescopic member 32 is wrapped by compression
The actuating of mechanically actuated, electromechanical, atmospheric pressure or the hydraulic pressure of the spring contained and realize, thus by telescopic member 32
It is retracted in compression set 22.Other can be used and extends and retracts device, the device including being configured to manual operation etc..
(for example, seeing Fig. 6 to 8).Compression assembly 22 can also include the mechanism for adjusting the amount of deflection for being applied to screen assemblies 20.This
Outside, the amount of deflection for being applied to screen assemblies 20 can be conditioned by the optional power calibration of user.
