Abstract
The invention relates to a press, especially for pressing straw material into briquets. The press has a number of press chambers open at either end and a number of pistons, the press chambers and pistons being connected to guiding means and driving means so that the pistons are moved inwards and outwards in relation to the press chambers at one end thereof for introducing press material in portions, pressing the press material and moving it to the other end of the press chambers where it is delivered. The pistons have a smaller outer extent than the inner extent of the press chambers in the engagement region of the pistons. Hereby some advantages are obtained.
Claims10
A press, especially for pressing straw material or the like into briquets while preventing such material from being cut, which comprises a plurality of press chambers of substantially uniform size and shape aligned in a straight line tandem with respect to each other, each of said press chambers comprising an entrance region, an exit, and an intermediate compaction zone for passage of said material therebetween, the widths of said entrance, exit, and intermediate compaction zone being substantially uniform, a number of elongate piston means associated with corresponding ones of said chambers;
- said piston means each being reciprocable into and from said compaction zone of its associated chamber and having a given compaction face area lesser than the area bound by the marginal edges of said chamber at the entrance region to said compaction zone to define a clearance between the piston means and said edges in that region, said piston means being further characterized in that its terminal portion is narrow enough to pass through said entrance region, exit and intermediate compaction zone of the chamber with which it is associated without contacting the marginal side portions of said chamber, and wide enough to compact said material within said chamber without cutting or severing said material within said chamber.
A press, especially for pressing straw material or the like into briquets while preventing such material from being cut, which comprises a plurality of press chambers of substantially uniform size and shape aligned in a straight line tandem with respect to each other, each of said press chambers comprising a relatively wide portal for receiving such material, an exit for discharging the material from the chamber, and a relatively narrow material-compacting zone communicating with said portal and constructed and arranged to provide a restricted passage for said material from the portal to said exit;
- a number of elongate piston means associated with corresponding ones of said chambers;
- said piston means each being reciprocable into and from said compacting zone of its associated chamber and having a given compacting face area less than the area bound by the marginal edges of said chamber at the portal region to said compacting zone to define a clearance between the piston means and said edges in that region, said piston means being further characterized in that its terminal portion is narrow enough to pass through said portal, exit and material-compacting zone of the chamber with which it is associated without contacting the marginal side portions of said chamber, and wide enough to compact said material within said chamber without cutting or severing said material within said chamber.
