US 8,800,779 B2 · Screen surface forming system

Abstract

A screen system having a plurality of screen elements that can be readily removed and replaced to vary one or more characteristics of the screen surface formed by the screen system. The screen system includes a support system for supporting at least one screen element to prevent deformation of the screen element that typically would occur due to the insufficient structural stability of the at least one screen element relative to the weight of the product being screened. Preferably, the support system includes one or more support elements that can be readily and easily installed and removed from the screen system. The support system is preferably configured to permit the one or more support elements to be positioned at different locations in the screen system. Preferably, the support system is configured to permit a variety of different support elements to be used to allow a greater variety of screen elements to be used.

A screening support system for use with a vibrating screen for screening material, the vibrating screen having a screening deck including a plurality of carriers for carrying said screening support system, said screening support system including:

(a) a plurality of screening element edge support members for supporting a plurality of screening elements having a plurality of openings formed therein through which a material to be screened passes, said plurality of screening element edge support members including a first screening element edge support member having a first connecting member for removably connecting said first screening element edge support member to one of said plurality of carriers, said first screening element edge support member having a first outwardly extending segment for supporting thereon a first edge of a first screening element, a plurality of recesses are formed in said first outwardly extending segment, each of said plurality of recesses being configured to receive a portion of one of a plurality of screening element section support members such that said first screening element edge support member extends at an angle to each of said plurality of screening element section support members, said first connecting member and said first outwardly extending segment being formed as one piece.

(a) a plurality of longitudinally extending screening element support members for supporting a plurality of screening elements having a plurality of openings formed therein through which a material to be screened passes, said plurality of longitudinally extending screening element support members including a first longitudinally extending screening element support member having a first connecting member for removably connecting said first longitudinally extending screening element support member to one of said plurality of carriers;
and,
(b) a plurality of transversely extending screening element support members extending from said first longitudinally extending screening element support member for supporting at least one of said plurality of screening elements, each of said plurality of transversely extending screening element support members having a first vertical surface, said first vertical surface of each of said plurality of transversely extending screening element support members extends along a first vertically extending side surface of said first longitudinally extending screening element edge support member and a first vertically extending side surface of said one of said plurality of carriers.

(a) a plurality of screening element edge support members for supporting a plurality of screening elements having a plurality of openings formed therein through which a material to be screened passes, said plurality of screening element edge support members including a first screening element edge support member having a first connecting member for removably connecting said first screening element edge support member to one of said plurality of carriers, said first screening element edge support member having a first outwardly extending segment for supporting thereon a first edge of a first screening element, a plurality of recesses are formed in said first outwardly extending segment, each of said plurality of recesses being configured to receive a portion of one of a plurality of screening element section support members such that said first screening element edge support member extends at an angle to each of said plurality of screening element section support members;
and,
(b) a plurality of transversely extending screening element support members for supporting at least one of said plurality of screening elements, each of said plurality of transversely extending screening element support members having a first portion seated in a corresponding one of said plurality of recesses, each of said transversely extending screening element support members being separate pieces from said plurality of screening elements so that:
(i) a configuration of the screening support system can be readily modified to vary the number of transversely extending screening element support members in the screening support system without varying the number of screening elements;
and,
(ii) each of the plurality of transversely extending screen element support members can be installed prior to installation of the corresponding screening elements.
