UN APARATO DE FILTRO DE CARGA LATERAL PARA FILTRAR GASES.

摘要

A filter chamber provided with a side wall having a row of uniformly spaced openings therethrough also has an end wall provided with an access door from which a track extends along the side wall below the openings. Filter units are insertable through the door for placement on the track. A rod extending lengthwise of the track and having an outer end accessible through the door is supported for axial movement back and forth parallel to the track between inner and outer positions. At longitudinally spaced intervals greater than the width of a filter unit lugs project from the rod, all in the same direction. There are as many lugs as the wall openings. The rod is rotatable to turn the lugs from positions in which they will overlap one side of filter units on the track to positions that permit the lugs to be moved to the opposite side of the filter units. The lugs are located on the rod in positions for moving filter units step by step along the track from alignment of each with one of the wall openings to alignment with another opening when the rod is moved back and forth, whereby to load or unload the filter chamber.
