A sieve has a fine wire mesh retained by a ring and two ring-shaped casing detachably linked to each other by clamping elements for clamping the wire mesh. The technical problem consists in designing a sieve into and out of which the wire mesh may be gently mounted, so that the wire mesh is not damaged. The edge of the flat wire mesh (7) is firmly secured to a wire ring (8), the first ring-shaped casing (1) ends in a rounded front flange (3) and the second ring-shaped casing (2) surrounds the front flange (3) with a radial ring-shaped shoulder (4), thus clamping the wire ring.

A particle size separator includes an upper separator frame, a lower separator frame, a screen disposed between the upper separator frame and the lower separator frame, a large size particle outlet having an inlet disposed below the screen, a small size particle outlet disposed in the lower separator frame and a combined baffle and seal unit disposed in an opening in the screen. The unit has a seal face configured to sealingly engage the inlet of the large size particle outlet. The unit has a baffle configured to constrain movement of particles on an upper surface of the screen into the inlet. The baffle is configured to sealingly engage an interior wall of the upper separator frame.

A cleaning machine for cleaning the ferrophosphorus ring of the anode includes a left end axle (2) and a right end axle (6), each of which respectively installs on one side of a roller (14). The left end axle (2) connects with an air conduit (1); the right end axle (6) connects with a shaft coupling (9); the shaft coupling (9) connects with a reducer (10); the input end of the reducer (10) connects with a motor (12) via a brake (11); the roller (14) is provided with air exhausts (4) and a roller door (15); and the right end axle (6) is provided with a fresh air inlet (7). The cleaning machine can purge the carbon block impurities, electrolyte impurities and other impurities from the broken phosphorous pig iron to recycle the phosphorous pig iron. It can decrease the resistance between the ferrum and the charcoal, operate stably and safely, and it is of simple structure.
摘要:
A system for screening fluid-borne material from a fluid that carries particulate matter along with the material, e.g. for screening usable fibers in papermaking or tissue making white water that also contains waste material such as fines and ash. The system employs a flexible and pliable screen to which the fluid is applied. The screen is supported in a suspended manner from a frame. The fluid is directed onto an inside surface defined by the screen, and the location at which the fluid strikes the screen is varied so as to result in bending and flexing of the screen due to the flexibility and pliability of the screen material. In this manner, the configuration of the screen drainage passages is continuously altered, to provide a self-cleaning action that prevents the screen passages from plugging or blinding over. In one form, the screen is generally frustoconical, and the fluid is applied to the inside surface of the screen in a manner which results in rotation of the screen. The material retained on the screen is directed toward a discharge opening defined by the lower end of the frustoconical screen, and the waste water including the particulate matter passes through the screen and is collected in a waste water collection tank. In another form, the screen is suspended from a frame to form a trough configuration having an open discharge end. The frame is movable in either an axial direction or a transverse direction, to cause movement of the screen and to obtain the desired flexing and bending of the screen to self-clean the screen drainage passages.
摘要:
A screening system having a resiliently mounted housing (100) with a screen (106) extending thereacross. The housing is vibrated by a low frequency vibratory drive using eccentric weights. About the peripheral frame of the screen, a high frequency drive or drives (146) is employed to vibrate the screen in the range of 20,000 Hz. The high frequency vibration is generated at the peripheral frame about the screen. The screen may be constructed to be responsive to the high frequency vibrations in a platelike manner rather than as a membrane. With the high frequency drives (146) mounted within the housing, a structure made of a plate extends from a mounting flange inwardly to a thin-walled plate (120) supporting the screen (106) and the high frequency drives (146) and inwardly to a collecting system including a trough (152) and a central dome (150). The center of the dome may be fixed to the screen and include a high frequency drive (146).
