FILTER MANUFACTURING DEVICE

摘要

The invention concerns a machine that fabricates - by winding up a profiled wire after a cylindrical spiral on a few bars and by welding the resulting bar spirals - a continuous slot filter that can be mounted, for example, into a drilled and cased hole that communicates with a porous environment containing pressure fluids that, in their turn, during the inflow, drive mechanical particles into the drilled hole through which the fluids are drawn out the surface.According to the invention, the machine includes a short shaft mounted into a roller bearing connected through a coupling to a long shaft screwed on the exterior and outfitted sideways with a key slot. The other end of the long shaft leans against an angular plain bearing, with one case fixed on a frame and a rolling disk and an apron roll that, together with a spacer, are fixed with a slotted nut on a block that the long shaft rotates through a blade. The long shaft is also supported by an intermediate bearing that can move alongside some guides, consisting of some radial-axial bearings mounted into a case on which are fixed, by means of a some plates and blades, a nut screwed on the shaft and block that supports an attachment disk connected to the long shaft through a blade. A profiled wire is connected to a sensitive switcher linked to the power supply circuit of an engine. The welding subassembly is located next to the angular plain bearing and controlled by a sensitive switcher mounted on the case of the angular plain bearing.
