Application filed September 18, 1911.
Serial No. 650,017.
To all whom it may concern:
.Be it known that we, HEINRICH BRUNE,
D., engineer, and HEINRICH HoRs'r, engineer, both subjects of the German Emperor, and residents of Frankfort on the Main, Germany, with post-oilice address Taunusstrasse No. 1, have invented .new and useful 1m which diflers from known devices of the kind for this purpose in that it renders possible a continuously and gradually increasing pressure. v
According to the invention the press consists of. two continuously running bands which act simultaneously as presses and as conveyers, the distance between them in the direction of travel gradually diminishing.
. In the accompan Ing drawings the invention is illustrated, igurel being a longitudinal section through the band press; Figs.
2 and 3 detail in views drawn to an enlar ed 1g. 1, drawn to an enlarged scale, these figures representing one form of the machine ac cording to the invention. Figs. 5-7 illustrate a modification, Fig. 5 being a sectional side elevation, Fig. 6 a section on line C--D of Fig. 5 and Fig. 7 one of the compressing chambers drawn to anenlarged scale.
The two endless bands traveling around the rollers 1 consist of perforated plates 2 made of two perforated pieces of sheet metal 'laid one upon the other so that the perforated ortrorisof one register only with a part .0 the, rforated portions of the other similar to e construction shown in Fi 7, in order that-only small openings wil be provided for the pa'ssa e of fluid, the solid material being prevente from passing therethrough. The plates are connected with each other by chain links 3 (Figs. 2 and 3). Between the lower and upper rollers 1 are arranged small pressure rollers 4, so that they lie in one plane and uide the band. On the. plates 2 are mounte at certain distances apart angle irons or the like constituting cross rails 5, while at the sides of the plates 2 are provided plates 6, which also may consist 0 angle irons or the like. The vertical distance between the rollers 1 or 4 issuch that the distance between the upper stretch of the lower band and the lower stretch of the upper band gradually diminishes. The height of the plates 6 is such that the compression chambers inclosed by them between the bands are completely closed laterally 'while the height of the cross rails 5 is such that they only gradually come to overlap, so that only gradually is there a complete closing of the rear wall of each compression chamber.
The material to be pressed is fed in a continuous length into the compression space between the bands and is thus subjected to a continuously and gradually increasing pressure. Lateral extrusion of the material is directly prevented" by the plates 6. At the beginning of the pressing operation a complete closure of the back wall is not necessary and at first there is only a partial rearward closure which increases with the increase of pressure. The cross rails enter into the material bein pressed like spades and convey it forwar until they cut t e length of the material into sections separated from each other, which ha pens when the material is subjected to the highest pressure. Notwithstanding this, the compressed material issues in the form of a continuous length. 7
This band press is particularly suitable for drying raw peat, coke, brown coal or the like, but it is also applicable for any other vegetable or mineral material containing water.
In the form shown in Figs. 5-7 the band 11, which travels over theupper hexagonal rollers 10, consists of single plates which are composed of two superim osed perforated sheet metal plates 12, 13 aid together so that the perforations of one register only Patented Mar. 11, 1913.
with a part of the perforated portions of each by a sheet metal plate 15, so that each of the combined lates constitutes a hollow carrier. The sti ening rails 14 also serve as links to connect the.several combined plates. The pressure rollers 16 of the upper band are carried by an endless chain 17, which simultaneously with the band 11, travels over rollers 18. The lower band consists of an endless chain 20 traveling over hexagonal rollers 19 and over pressure rollers 21 situated beneath the upper stretch. On the endless chain 20 are mounted the piston rods 22 ca rying the compressing pistons 23. ThelaTrer move in chambers 24 which move in a suitable guide 25 in such a manner that as the chain '20 travels the pistons 23 carry the chambers 24 with them. The side walls 26' of the chambers 24, which are parallel to the direction of movement of the band, are somewhat higher than the other sides. All the sides of the compression chambers, as well as the pistons, consist, lik the upper band 11, each of two perforated plates placed one over the other so that the erforations of one register with the not per orated parts of the other; This construction works as follows: Before the compression chambers come in'contact with the upper band 11, they are charged with the material to be compressed. As they move inthe direction of the arrow a under action of the movement of the upper v band 11' and the endless chain 20, there occurs, owing to the convergence of the chain and the band, a relative shifting of the compression chambers and the pistons as willbe clear from an inspection of Fig. 5. In this manner the material contained in the chambers is gradually and continuously more strongly compressed, whereby the water is expelled; through the perforated side walls of the chambers, the perforated pistons and the perforated upper band 11. The pressure can beraised to any degree that is desired by varying the convergence of the upper band and the endless chain 20. Theoretically indeed it is possible to compress the material originally chargedinto the compression chambers up to nil, practically the final pressure is selected so that it is that which is most advantageous for the material to be compressed. When the chambers leave the upper'band, there is a still further relative movement of the pistons and. the chambers until the pressingsurface of the pistons is level with the upper edge of the chamber, whereupon the compressed cake falls out.
In the construction shown the pistons are positively conveyed by the endless chain, while the compression chambers are moved along by the pistons and slide in the guide 25. Obviously the compression chambers may be positively moved and the pistons carried along by them. The'volumecan be diminished to any degree that is desired as is already stated. The length of material is in this case subdivided into'several sections by the compression chambers so that more surfaces for the escape of the water are provided. It is possible in this arrangement to obtain in the press any suitable shaped blocks by appropriate formation of the compression chambers. The formation of the pressure surfaces each of two perforated metal sheets, the perforations of one registering with the not perforated portions of the other, has the advantage of easy and cheap construction, and that the material under pressure is only so far pressed into the perforations as is necessary for the filtration of the water to be expressed, it
