Among the innovations developed and marketed by S.C. Costruzioni Meccaniche, headquartered in Empoli (Florence) and specialized in the production of tannery machines and purification plants, stands out Belt Filter, the self-cleaning belt grid for duct installation.
The structure of this machine is completely made of stainless steel AISI 304, consisting of two sides and spacer columns. The through-feed belt filter, is made up of teeth featuring an exclusive patented self-cleaning profile, made of a plastic material which is resistant to wear and acids, assembled on shafts made of stainless steel AISI 304, counting a pitch of 100 mm or 225 mm.
The belt is laterally provided with stainless steel AISI 304 plates that intersect so to form a continuous barrier against the lateral leakage of the screened material. At the base, a nylon brush prevents the passage of solid bodies through the space of tooth rotation. The belt is able to separate, from the slurry, the solids suspended and funnel them to the top of the machine where, thanks to the particular shape of the tooth, at the time of the inversion of the motion of the belt, the self-cleaning starts, made more effective from the use of a counter-rotating brush in the point of discharge. This way, the solids fall by gravity to the pre-set spot.
The counter-rotating nylon brush is driven by a motor and is mounted on a stainless steel AISI 304 shaft, propped up by supports and grease-lubricated bearings. Both the traction shaft of the belt, propped up at its ends by supports and sealed bearings, lubricated by grease and the slide, developed for conveying the screened material at the discharge point, are also made of stainless steel AISI 304, as well as the cleaning pipelines of the belt filter.
Belt Filter is equipped with the gear motor, coming from one of the best Italian producers, lubricated with long-life oil, keyed directly onto the traction shaft of the belt itself. On the gear unit there is an electromechanical torque limiter able to avoid any damage to the belt, in case of abrupt stop caused from large solid particles dispersed in the slurry. The sump is fixed with screws to the structure which supports and protects all the moving parts of the portion of the grid that comes out of the channel and is made of stainless steel AISI 304 in line with the current safety regulations.
