Abstract:
A vibratory plate screen having a first end for quickly mounting in a vibrator housing, an intermediate region with openings therein and a securement end that allows one to quickly secure a vibratory plate screen in a vibratory housing. In addition, the screen is sufficiently flexible to enable one to mount the vibrator screen in a curved condition or stressed condition so that the inherent tensile strength of the material assists in holding the vibratory plate screen in position. A further feature of the invention is the quick removal and securement of the vibratory plate screen.

The elongated body defines an upper recess configured to engage with one or more screen panels, the elongated body further defines a lower recess configured to engage a support member of a screening apparatus. Each of the first end and second end includes a two-platform structure, the two-platform structure configured to engage with another two-platform structure, wherein the first platform is offset from the second platform. Further, the first platform is adjacent to the second platform, and the second platform is laterally and vertically offset from the first platform, and the first platform is in a first plane and the second platform is in a second plane. The elongated body may further define first and second opposed, upper sidewalls extending upwardly along the length of the elongate body, the first and second opposed, upper sidewalls defining the upper recess, and first and second opposed, lower sidewalls extending downwardly along the length of the body, the opposed lower sidewalls defining the lower recess.
Abstract:
A screening assembly 10 includes at least one rail 14 to be secured to a support member of a screening machine to lie parallel to, and intermediate, side members of the screening machine. At least one retaining formation 18 stands proud of an operatively upper surface of each rail 14. The assembly includes a plurality of screening modules 12. Each screening module 12 comprises a supporting structure 64 and a removable screening element 66. The supporting structure 64 has an end supported on the rail 14 so that a pair of supporting structures 64 lie in end-to-end abutting relationship with the abutting ends, in use, overlying the rail 12 and defining a receiving formation through which the retaining formation 18 protrudes to project beyond the receiving formation into a recessed region defined by the abutting ends of the pair of supporting structures 64. A locking member 46 is associated with the receiving formation and is receivable in the recessed region for engaging its associated retaining formation to lock the pair of supporting structures with respect to each other and with respect to the rail 14. An upper surface of the locking member 46, when the locking member is received in the recessed region, lies substantially at or below the level of an operatively upper edge of the supporting structure.
Abstract:
A screening panel 10 comprises a peripheral frame 12 consisting of a pair of mutually laterally spaced side members 14, 16, which are integral with a pair of mutually axially spaced end members 18, 20. The side members 14, 16 and end members 18, 20 define corners of the panel 22.1, 22.2, 22.3 and 22.4 and the peripheral frame 12 where they meet. A plurality of mutually spaced ribs 15 extend across the periphery of the panel 10 to define a screening surface. The side members and end members are rectangular in cross-section, thereby defining substantially flat upper peripheral surfaces 12.1, outer peripheral surface 12.2 and lower peripheral surface 12.3 of the peripheral frame 12 and thus also the panel 10. The panel 10 includes locating recesses 24 provided at or near to the corners 22.1, 22.2, 22.3 and 22.4 of the panel 10. The panel 10 also has separate securing recesses in the form of semi-circular grooves 30 formed in the lower surface 12.3 of the panel 10, around the locating recess 24 and concentrically therewith.
Abstract:
A screening machine of the type used to separate or classify mixtures of solid particles of different sizes includes a fixed base and a perforate screen mounted for movement relative to the base during a screening operation. The screens are pre-tensioned and mounted in a perimeter frame for separating various granular and particulate material. The frame is slid into the side of the machine in a direction parallel with two opposing bevel lips at the ends of the frame which mate in the screening machine with a complementary channel such that when the screen is raised into sealing contact in the screening machine, the bevel ends of the screen panel frame align the screen panel in the machine. The bevels on the screen panel frame provide a positive sealing surface for contact with the adjacent portions of the channel to prevent product from escaping off of the screen during use. The sealing contact of the screen panel is enhanced by a seal member on the screen panel.
Abstract:
A screening machine includes wall members, a screen assembly, and a compression assembly. The screen assembly includes a frame with a plurality of side members and a screen supported by the frame. The compression assembly is attached to at least one wall member and forms the screen assembly into a concave shape.
Abstract:
In a cylindrical sieve, a first frame 7 is provided with a first ring plate 7a arranged in a radial direction and a ring plate 7b extended inward in an axial direction X of the sieve from an inner end of the first ring plate 7a. The ring plate 7b has an inwardly warped end. A ring projection 2a is fit in a ring-shaped cavity K1 defined by a ring recess 10a and the first frame 7. The ring plate 7b presses the ring projection 2a outward in the radial direction to prevent the ring projection 2a from being slipped off the matching recess. Through holes 7c (counter bores) are formed in the first frame 7 along the axial direction X. Four of the through holes 7c are used to fasten the rods 6 and receive the Phillips head screws 6f seated therein, and the remaining through holes 7c receives Phillips head screws 20 (see FIG. 1) seated therein for reinforced linkage of the first frame 7 with the holder frame 11.
