Abstract
The present invention relates to a method and a machine for compacting waste material, in particular metallic scrap, and to a block of compacted material obtained with this method. The method according to the invention has the peculiarity of comprising: a first step of feeding a first amount of material to be compacted into a compression chamber (3), a first step of compression of the material fed into the compression chamber (3) along at least one preset direction to obtain a first compacted portion (20a). Subsequently at least one second step of feeding a second amount of material to be compacted is performed, followed by a second compression step with which the second amount of material is in turn compacted in the compression chamber (3) which still accommodates the first compacted portion (20a). In this manner a single block is obtained, formed by at least two compacted portions (20a, 20b) which, if required, can again be broken up into the compacted portions which compose it.
Description
- The present invention relates to a method and to a machine for compacting waste material, in particular metallic scrap, and to the block of compacted material obtained with this method.
- In the field of waste material to be recycled, presses are known which perform the compaction of the material obtaining a considerable reduction of its original volume so as to facilitate its transportation from the location where it is stacked, to the industry which provides the grinding and recycling of the recyclable material.
- On order to feed the machines which perform the grinding, it is necessary for the blocks of compacted material not to exceed preset dimensions, since beyond these dimensions there would be great difficulty, if not impossibility, on the part of the grinding elements to process the blocks.
- In the other hand, this requirement clashes with the needs of who performs the compaction of the scrap, since the reduced dimensions of the compacted block significantly increase the duration and therefore the cost of the loading and transportation of the compacted blocks.
- The aim proposed by the present invention is to eliminate the above described disadvantages by devising a method for compacting waste material which allows to obtain blocks of compacted material with dimensions such as to allow the possibility of quickly loading them, yet being processable "appetizing" for grinding machines.
- Within the scope of this aim, an object of the invention is to provide a machine for performing this method which is easy to manufacture and which is highly reliable in operation.
- This aim, as well as this and other objects which will become apparent hereinafter, are achieved by a method for compacting waste material, in particular metallic scrap, characterized in that it comprises: a first step of feeding a first amount of material to be compacted into a compression chamber, a first step of compression of the material fed into said compression chamber along at least one preset direction to obtain a first compacted portion, at least one second step of feeding a second amount of material to be compacted into said compression chamber containing said first compacted portion, at least a second compression step along said preset direction to obtain at least one second portion joined in a separable single block to said first compacted portion, and a step of unloading said block out of said compression chamber.
- The method according to the invention may be preferably, but not exclusively, provided by a machine comprising a framework internally defining a compression chamber slideably accommodating a first piston operable for reducing the useful volume of said chamber for compacting the material inserted therein, characterized in that, at the end of the chamber opposite with respect to the head of said first piston, is defined a containment region adapted for accommodating at least two portions, compacted and joined into a single separable block.
- The compacted block of waste material which is obtained by the method according to the invention is characterized in that it comprises at least two portions compacted in sequence and joined into a single block which can be split into said two portions.
- Further characteristics and advantages of the invention will become apparent from the description of a preferred, but not exclusive, embodiment of the method according to the invention and of the machine for the execution thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- Fig. 1 is a lateral elevation view of the machine for performing the method according to the invention;
- Fig. 2 is a perspective view of the machine;
- Fig. 3 is an enlarged top plan view of the machine;
- Fig. 4 is a partially cut-away enlarged lateral elevation view of the machine;
- Figs. 5 and 6 are schematic and partial cross-section lateral elevation views of the machine, illustrating some steps of the method according to the invention;
- Fig. 7 is a schematic partial cross section top plan view of the machine, illustrating another step of the method according to the invention;
- Fig. 8 is a cross section view of a portion of the machine, illustrating the step of unloading the block out of the compression chamber; and
- Fig. 9 is a perspective view of the compacted block of waste material obtained with the method according to the invention.
- With reference to the above described figures, the machine for performing the method according to the invention, generally indicated with the
reference numeral 1, comprises aframework 2 which defines acompression chamber 3 intended to accommodate the material to be compacted, composed, e.g. of thecar wreckage 4. In the compression chamber 3 afirst piston 5 is accommodated, controlled e.g. hydraulically, which can be controllably operated to reduce the useful volume of thechamber 3 giving rise to the compaction of the material contained therein. In order to facilitate the introduction of the material to be compacted, it is possible to provide aslide 6 at the inlet opening 7 of thechamber 3. - At the upper edge of its head, the
piston 5 is provided with ablade 8, which as the piston advances abuts acutting edge 9 matchingly provided on one side of the inlet opening. This cutting edge is suitably slanted with respect to the direction of advancement so as to obtain, as thepiston 5 advances, a gradual shearing of the scrap which is introduced into thechamber 3. - At the opposite end of the
chamber 3 with respect to the head of the piston, a containment region 3a is defined which is adapted for containing at least two compressed portions produced by two compressions in sequence of amounts of material introduced into thechamber 3. - At this containment region, a
second piston 10 is provided, arranged with an axis which is substantially perpendicular with respect to the axis of thefirst piston 5 which, like the latter, can be operated hydraulically to reduce the useful volume of the containment region 3a. - In the part opposite to the head of the
piston 10, aport 11 is arranged which is slideable withinvertical guides 12, and which can be controllably raised by means of a pair ofhydraulic pistons 13 to allow the expulsion from thechamber 3 of the compacted material. - For the sake of descriptive completeness, it should be added that the
framework 2 can be provided withwheels 14 and with acoupling bar 15 to obtain the easy shifting of the machine. Furthermore, the part of theframework 2 which supports thesecond piston 10 is hinged to the remaining part so that is is possible to rotate it substantially through 180° to obtain a reduction of the transverse dimensions of the machine during transport, as illustrated in Fig. 3. - In order to perform the method according to the invention, the
machine 1 is operated as follows. - Initially, there is a first feeding step, in which a first amount of scrap is fed into the
compression chamber 3. If the scrap has large dimensions, it will be inserted only partially into thechamber 3 inserting it into the inlet opening 7. The first feeding step is followed by a compression step in which thefirst piston 5 is advanced (Fig. 5). By virtue of the advancement of thepiston 5, the part of scrap inserted into thechamber 3 is sheared and subsequently compacted along at least one preset direction, in the case illustrated, in the direction of advancement of thepiston 5. - As a consequence of this first compression step, a first compacted
portion 20a is obtained which remains in the containment region 3a when thepiston 5 is moved back (fig. 6). - The backward motion of the
piston 5 once more frees the inlet opening, which was closed during the compression step by the skirt of thepiston 5, and then there is a second feeding step, in which a second amount of scrap is fed into the compression chamber. - Subsequently, a second compression step is carried out, in which the second amount of material is compacted against the first compacted
portion 20a and constitutes a second compacted portion 20b which, by virtue of the high pressures usual in these machines, forms a single block with thefirst portion 20a. - The second compression step may be followed by other feeding and compression steps until the compacted block reaches preset dimensions, compatible with the ones of the
port 11. - At the end of the last compression step, with the
first piston 5 in contact with the compactedblock 20, thesecond piston 10 intervenes, performing on the block an additional compression in a direction substantially perpendicular to the preceding compressions. This additional compression has the effect of increasing the cohesion between the compactedportions - At the end of this operation, the
port 11 is raised and theblock 20 is expelled from thechamber 3 by means of thesame piston 10. - The
block 20 which is obtained with the described method has a cohesion between the various compactedportions portions - In practice, it has been observed that the method according to the invention fully achieves the intended aim since it allows to compact the waste material into blocks with dimensions such as to be easily loadable, or unloadable, on means of transport; such blocks, once they have reached the recycling industries, may then quickly split into the compacted portions which composed them and which have dimensions suitable for feeding the grinding machines.
- A further advantage is that of having provided a machine for performing the method according to the invention which is easy to provide and which is highly reliable.
- The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept; moreover, all the details may be replaced with technically equivalent elements.
- For the sake of simplicity, the invention has been described with specific reference to metallic scrap, though it is understood that the same method can also be applied to other waste materials, which have problems similar to the ones described above.
- In practice, the materials employed for the construction of the machine which performs the method according to the invention, as well as its dimensions, may be any according to requirements and state of the art.
