Definitions

• the invention relates to a lamellar construction for treating liquids, in particular for separating foreign matter from liquids, bringing in contact liquids with a gaseous substance, for biological treatment or cooling;
• the construction contains mutually parallel channels, the wall of the channels being formed by circular cross-section partitioning elements preferably with identical radii, in such a manner that the edges of the individual circles are disposed at the centres of the inside of the adjacent circular elements or are connected thereto, furtheron the centre-point of the arcs coincide with the every second intersection point of a square or rectangular matrix, the spacing of which is larger than the radius of the circular arcs.
• the aim of the invention is to develop the lamellar structure having been mentioned in our preamble in such a manner that partly the desired surfacial smoothness could be obtained, partly the lamellar structure could be produced by using modern methods of high productivity.
• the task set is solved in such a manner that a lamellar construction containing parallel channels, - in which the wall of the channels are formed by circular cross-section partitioning elements preferably with an identical radius, whereby the edges of the individual circles are disposed at the centres of the inside of the adjacent circular elements or are connected thereto, furtheron the centre-point of the arcs coincide with the every second intersection point of a square or rectangular matrix, the spacing of which is larger, than the radius of the circular arc, - is composed of longitudinal profile elements being essentially confined by the quarters of a circular arc and having a closed cross-section and in which said quarters of the circular arcs are confining one or more longitudinal channels, and on the profile elements, along the outer contours, in a mutual pitch of 90°, longitudinal connecting elements being parallel with the axes of the profile elements are formed.
• the profile element consists of four symmetrically arranged concave quarters of the circular arc which are practically meeting in a peak on two opposite sides, while on the other opposite sides they are interconnected by a bridge, forming in such a manner a closed channel, furtheron the connecting elements are arranged at the peaks and the bridges.
• the cross-section of the profile element is formed by four convex quarters of the circular arc and within the circle having been formed in such a manner four concave quarters of a circular arc are arranged, which are meeting in a peak on the two opposite sides, while on the other two opposite sides they are connected to the closed circle with a spacing; in such a manner within the closed circle four channels with identical cross-sections will be formed, while one channel has a different cross-section, I n this case, the connecting elements are arranged outside the closed circle, at the meeting points of the concave quarters of the circular arcs. With both embodiments the connecting elements can be shaped in a different manner.
• One advantageous method lies in that out of the four connecting elements of the profile element three are formed as an insertable plug-in type, while the fourth is a multi-parted receiving connecting element of the female type.
• connecting elements two are of the plug-in-type, while the other two of the famel type.
• All the embodiments can be characterized in that the profile elements and the connecting elements can be manufactured by extrusion.
• the profile element forming the structural unit of the lamellar construction can be manufactured by extrusion in an optimal manner, with a high producting speed and with an economical technology;
• the lamella-bodies can be manufactured in compliance with the different destinations, resulting in a high-grade flexibility of the system;
• the profile elements of the lamellar construction having been formed in accordance with the invention by extrusion may be prepared of different materials in dependence of the destination, whether the construction is for the purification of dring water, oil-contaminated sewage, or normal sewage, etc.; - by using the lamellar construction according to the invention comprising the profile elements, by means of the connecting elements disadvantageous and wearisome assembly operation, as e. g. gluing, can be eliminated. In such a manner a higher productivity, more economical concentration and pre-fabrication become possible;
• a continuous lamella-field of optional size and magnitude can be form ed;
• the connecting elements render the lamellar construction releasable, that means, that the single profile elements can be exchanged, e. g. when the technological ducts are crossing the lamellar structure in the object. In such a case one or two profile elements may be left out and the problem of crossing is immediately solved;
• the profile elements according to the invention so-called lamella-bodies of higher loadability, accordingly of larger dimensions can be prepared, as a result, the dimensions of the supporting steel structures may be smaller, also resulting in material savings;
• the single elements may be easily removed, - e. g. for the sake of control or re-arrangement -, it goes without saying that the whole system can be disassembled in the same easy manner.
• Fig. 1 is a schematic sectional view of the profile element consisting of the concave quarters of the circular arc
• Fig . 2 the cross-section of a part of the lamellar construction having been built up of the profile elements according to Fig. 1,
• Fig. 3 is a sectional view of the profile element with a cross-section consisting of the concave and convex quarters of the eircular arc
• Fig. 4 is a part of the lamellar structure having been built up of the profile elements shown in Fig. 3.
• the profile element 1 is having a cross-section composed of four concave quarters of a circular arc. On the two opposite sides the concave quarters of the circular arc 2 are meeting in the peak 3, while on the other two opposite sides they are inter connected by means of the bridge 4. In such a manner a closed channel 7 is formed in the profile 1.
• the longitudinal connecting elements running parallel with the longitudinal axis of the profile element 1 are arranged at the peaks 3 of the profile element 1 and on the bridges 4.
• the profile element 8 is formed of four convex quarters of a circular arch 9, which are forming collectively a closed circle.
• four concave quarters of a circular arc 2 are arranged so, that their two opposite sides are meeting in the peak 3, while the other two opposite sides are connected to the closed circle with the spacing 10.
• four channels 7 with identical cross-sections are formed, while there is a further channel 7 with a different cross-section.
• the connecting elements are to be found, i. e.
• the connecting element 5 of the plug-in-type is arranged, while at the other spacing 10 the receiving connecting elements 12 and 13, respectively, of the female type are to be found.
• the connecting elements 12 and 13 are of different formation, however they can be formed in the same manner.
• Fig. 4 the construction of the lamella-structure with the profile elements 8 is shown. It can be well seen in which manner the profile elements 8 are connected by means of the connecting elementd 5, 12 and 13.
• Both the profile element 1 and 8 are made by extrusion, the basic material to be used is in compliance with the field of application, i. e. whether drink water, oilcontaminated sewage, normal sewage are to be purified.
• the connecting elements are extruded together with the profile elements, that means that completely finished profiles are leaving the extruder.
• the profile 1 may be prepared with the connecting elements 12 and 13, similarly the profiles 8 may be provided with the connecting element 6.
• the connecting elements themselves may be prepared in several forms differing from those specified here.
• a connecting element may be developed which is universal, i. e. it can be equally used as an inserted and a receiving element, respectively.
