摘要:
A vibratory screener including a screen with an upper surface, a lower surface, and a plurality of apertures, an attachment post extending above the upper surface of the screen, and a cleaning system positioned above the upper surface of the screen. The cleaning system includes a support plate, a plurality of arms extending radially from the support plate, and at least one brush extending downwardly from each of the arms. Each brush is positioned so that the distal end of at least one of its multiple bristles contacts the upper surface of the screen. The screener further includes a collection area positioned below the lower surface of the screen and a vibration generator that vibrates the screen and the cleaning system and causes the arms to rotate relative to the upper surface of the screen.

Die Erfindung betrifft ein Sieb, insbesondere eines Siebkastens von Sieben für Plansichter. Die zu lösende Aufgabe bestand darin, Siebe bzw. Siebkästen einfach und sicher horizontal im Plansichter zu verspannen. Die Lösung der Aufgabe erfolgt mittels Verspannen der Siebe über mindestens zwei Ecken, wobei der Siebkasten (4) des Siebes abgeschrägte Ecken mit Flächen (7) aufweist.
摘要:
An air density separator (20) has a vertical air separation chamber (24) that opens downwardly to allow rejected material (54) to fall out from the chamber (24) through the open bottom. The air density separator (20) is configured to recirculate the air and entrained fines, and so minimizes emissions and costly air treatment processes. The air separation chamber (24) is connected by a first duct (26) to a cyclone (28). A fan (30) is positioned adjacent the lower end (34) of the air separation chamber (24), and draws air through a second duct (27) out of the cyclone (28) for reintroduction into the air chamber (24). The fan (30) by way of the cyclone (28) draws air through the first duct (26) from the air separation chamber (24). The fan (30) exhausts into the vertical air separation chamber (24) below the material infeed (61) through the plenum (31). An oscillation screen (36) composed of bars (38) extends into the separation chamber (24) of the air density separator (20) and is used to disperse material into the separation chamber (24). The bars (38) are spaced apart to allow air to be drawn up through the bars (38) to separate the light component (56) in the feed material (44) from heavier materials (54). A tray (61) to which the bars (38) are mounted are caused to oscillate by an eccentric weight (50) which is mounted to the bars (38) and driven to oscillate in a horizontal plane. The tray (61) is suspended by four universal linkages (47) to a support frame (46), the linkages (47) allowing the tray (61) and attached bars (38) to oscillate.

Die Erfindung betrifft eine Vorrichtung zur Reinigung von Sieben, insbesondere die Siebe von Plansichtern in Mühlen, welche eine grössere Zahl Siebstapel (16) mit z.B. über 20 Siebkasten (1) aufweisen. Es wird vorgeschlagen, Siebrahmen 3, ohne Tragrost auszubilden, und diese in bespanntem Zustand auswechselbar und auf, bzw. in die Siebkasten (1) einlegbar auszugestalten. Dadurch wird zwischen dem Siebgeweben (10) sowie einer flachen Bodenplatte ein freier Produktdurchfall- bzw. -abführraum (11) gebildet. Die Siebreiniger (6, 6') werden auf der flachen Bodenplatte (4) auf- respektive eingelegt. Besonders bevorzugt werden die Siebrahmen (3) als Metallrahmen ausgebildet. Die Siebreiniger (6, 6') reinigen das Siebgewebe (10) und räumen das Produkt auf der Bodenplatte (4) aus, wozu 2-, 3- oder 4-armige Formen vorgeschlagen werden.
摘要:
The sieve device is used as a feeder and separator of materials which are difficult to separate such as household refuse, industrial waste, cumbersome or dry waste. In order to achieve an optimun distribution and cleaning effect, there are provided two superposed screen sieves (12, 13) comprised of overlapping bars having a conical cross-section and which are free at their ends. The cleaning effect of the device is improved by the step offset of the sieves (12, 13) and by the circulation effect resulting therefrom. The oscillation motion is obtained by means of oscillating elements made of rubber and by an uneccentric drive.

An orbital shaker device (1) for biotechnological and/or biomedical applications comprises a frame (10), a platform (15) for receiving biotechnological and/or biomedical containers (50), eccentric couplings (13, 14) for allowing an orbital movement of the platform (15) relative to the frame (10), counterweight units (17, 18) for balancing the orbital movement, and at least one motor (19) for driving the eccentric couplings (13, 14). The device comprises two eccentric couplings (13, 14) arranged near respective opposite edges (27, 28) of the platform (15), while each counterweight unit (17, 18) is arranged approximately in the plane of the combined center of gravity of the platform (15) and the containers (50). Furthermore, both eccentric couplings (13, 14) are driven by the motor (19) or motors, either directly or indirectly. In this way, an optimal vibration compensation is achieved while allowing an imaging unit (40) to be mounted underneath the platform (15).

Apparatus having a drivebox including a motor, a drive connected to the motor, a suitable number of adjustment brackets, and a set of adjustment gussets. A basket is connected to the drivebox through the adjustment brackets and adjustment gussets, and drivebox imparts a sifting motion onto the basket. The basket has a housing, an infeed end, an discharge end, at least one screening deck contained therein, and positioned at a screening deck angle. The apparatus is of a modular design which enables changing the screening deck angle while installed in a facility and without substantial disassembly.
