Title
(EN) PUMP STRAINER WITH PNEUMATIC CLEANING
(FR) CRÉPINE DE POMPE À NETTOYAGE PNEUMATIQUE
Abstract
(EN) The present invention provides a strainer for use with a water pump in a mine that includes a grill for preventing the ingress of solid material over predetermined dimensions, and an air discharge structure positioned so as to produce a continuous flow of air to remove the material from at least part of the grill, so that flow is maintained through the strainer.
(FR) La présente invention concerne une crépine destinée à être utilisée avec une pompe à eau dans une mine qui comprend une grille pour empêcher l'entrée de matériau solide sur des dimensions prédéterminées, et une structure de décharge d'air positionnée de façon à produire un écoulement continu d'air pour éliminer le matériau d'au moins une partie de la grille, de telle sorte que l'écoulement est maintenu à travers la crépine.
