The stage casing cylindrical sieve of described screen assemblies is not restricted to straight cylinder shape, can be taper barrel, straight polygonal cylinder or polygonal pyramid tubular yet, or any combination shape of these shapes.
The stage casing cylindrical sieve of described screen assemblies also can be Arbitrary 3 D plane or curved surface.
The bottom screen of described screen assemblies is not restricted to flat-surfaced screen, also can be on-plane surface screen cloth, as taper barrel or other three-dimensional planar or curved surface.
Described screen assemblies can cancel bottom screen, only retains stage casing cylindrical sieve, especially during stage casing cylindrical sieve employing cone barrel structure.
Described vibration input lever does not limit and is arranged on the screen frame of bottom screen, on the screen frame that yet can be arranged on stage casing cylindrical sieve or on vibration-sensing rod assembly.
Transmission is passed to screen assemblies by vibration input lever by vibrational energy device by described vibration-sensing rod assembly, and described vibrational energy device is not restricted to ultrasonic vibration apparatus, pneumatic vibrator unit or electric vibrating device, also can be other vibrative device.
The vibrational energy device that described vibration input lever is passed to screen assemblies is not restricted to a vibrating device, also can configure multiple, multiple vibrating device used in combination simultaneously.
The high pressure gas blast cleaning device of the configurable Automatic clearance screen cloth of described screen cloth casing assembly or other cleaning plant, be convenient to automation cleaning screen cloth and the surface that contacts of powder.
Described powder inlet passage and dust outlet passage can be arranged in the powder channel of negative pressure, normal pressure or malleation, for realizing the screening function of Dual-Phrase Distribution of Gas olid closed cycle.
The beneficial effects of the utility model are: adopt the utility model of said structure screen cloth to be decomposed into lower screen and stage casing cylindrical sieve two parts, when certain powder path sectional area, required total screen area can be reached by the height increasing stage casing cylindrical sieve, can screening efficiency be improved; After powder path sectional area reduces simultaneously, powder to be sieved can at screen assemblies building up inside, due to the gravity effect that powder superposition produces, under vibrating conditions, promotion lower floor powder is penetrated stage casing cylindrical sieve and bottom screen by upper strata powder, can improve sieved through sieve ability by a relatively large margin; Significantly reduce the sectional area in powder path, due to the miniaturization of size, this vibratory sieve can realize all surface in automation cleaning screen cloth and powder path, without the need to clearing up manually.
