Title (EN) DEBLINDING APPARATUSES AND METHODS FOR SCREENING
(FR) APPAREILS DE DÉBOUCHAGE ET PROCÉDÉS POUR LE TAMISAGE
Abstract:
(EN) Deblinding apparatuses and deblinding methods are provided. A deblinding apparatus may include a support frame (120) including a grid structure (130) and multiple compartments (124). Multiple scattering members (134a, 134b) may be disposed within a compartment. Scattering members be removably affixed to a portion of the grid structure that forms a part of a compartment. Multiple unsecured objects (138) may be placed within a compartment. When attached to a screen and in response to movement of support frame (120), at least one unsecured object of the multiple unsecured objects (138) may collide with a first scattering member (134a, 134b) and with a surface of the screen to thereby cause deblinding of the screen. Sizes, shapes, masses, and morphologies of unsecured objects (138) may be designed to optimize collision rates of unsecured objects with scattering members (134a, 134b) and with the screen assembly (120).
(FR) L'invention concerne des appareils et des procédés de débouchage. Un appareil de débouchage peut comprendre un cadre de support (120) comprenant une structure en grille (130) et de multiples compartiments (124). De multiples éléments de dispersion (134a, 134b) peuvent être disposés à l'intérieur d'un compartiment. Des éléments de dispersion peuvent être fixés de manière amovible à une partie de la structure en grille qui constitue une partie d'un compartiment. De multiples objets non fixés (138) peuvent être placés à l'intérieur d'un compartiment. Quand il est attaché à un tamis, et en réponse à un mouvement du cadre de support (120), au moins un objet non fixé parmi les multiples objets non fixés (138) peut venir en collision avec un premier élément de dispersion (134a, 134b) et avec une surface du tamis, de façon à provoquer ainsi un débouchage du tamis. Des tailles, des formes, des masses et des morphologies d'objets non fixés (138) peuvent être conçues de façon à optimiser des vitesses et fréquences de collision d'objets non fixés avec des éléments de dispersion (134a, 134b) et avec l'ensemble de tamis (120).
